Numerous materials of the invention are available, provided they are resistant to softening, scorching, flammability, or deterioration to the heating temperatures of common microwave ovens, eg, 250 ° F to 425 ° F. Suitable for use in forming blanks and components. The particular materials used include microwave interacting materials, and microwave transmissive materials or inert materials.
For example, any blank or component of the present invention comprises one or more functions that alter the effect of microwave energy during the heating or cooking of foodstuffs. For example, blanks or components promote browning and / or crisp finish of specific parts of the food product, blocking specific parts of the food product from microwave energy and overheating the food product. At least from one or more microwave energy interacting components (hereinafter sometimes referred to as "microwave interacting components") that prevent them from being slaughtered or transfer microwave energy to specific parts of the food product. It may be partially formed. Each of the microwave energy interacting components absorbs microwave energy and transmits microwave energy as needed or as desired for the specific microwaves that heat the components and foodstuffs. It comprises one or more microwave energy interacting materials or fragments arranged in a particular configuration that reflect or direct microwave energy.
The microwave energy interacting component can also be supported on top of the microwave inert substrate or transmissive substrate for ease of handling and / or prevention of contact between the microwave interacting material and the food product. For convenience, but not limited to, the microwave energy interacting components supported on top of the microwave transmissive substrate are understood to include microwave interacting components or elements, and microwave inactive components or elements. The components are referred to herein as "microwave interacting webs".

Examples of metal oxides suitable for use in the present invention include, but are not limited to, oxides of aluminum, iron, and tin with conductive materials at the required sites. Another example of a metal oxide suitable for use in the present invention is indium tin oxide (ITO). ITO is applied as a microwave energy interacting material and provides overheating effect, protective effect, browning and / or crispy finishing effect, or a combination thereof. For example, ITO may be sputtered onto a clear polymer film to form a susceptor. The sputtering process is generally carried out at a lower temperature than the evaporation dissociation process used for metal attachment. Since ITO has a more uniform crystal structure, it is transparent even at the site where the coating thickness is maximum. In addition, ITO can be used for the purpose of heat curing or dispersion control effects. Since ITO has fewer drawbacks than metals, ITO thick coatings are more manageable than metal thick coatings such as aluminum.
Alternatively, the microwave energy interacting material may include suitable conductive, semi-conducting, or non-conductive artificial derivatives, or strong derivatives. Artificial derivatives include polymers or other suitable matrices, or conductive and fragmented materials in the binder, which may include debris of conductive metals such as aluminum.

There is also). When supported on a film or other substrate, these components are referred to as "susceptor film" or simply "susceptor". If the substrate is a blank, carton, or component containing multiple panels, the susceptor may be applied to all or part of one or more panels to form at least a portion of the substrate adjacent to the food product. .. As an example, but not limited to, susceptor M is applied to at least a portion of blank 100 (not shown in FIG. 1A, which illustrates aspects of the blank forming the outer surface of the component), FIGS. 1B, 1C, and As shown on the 1st floor, at least a part of the inner surface of the component 178 may be formed. However, other microwave energy interacting components disclosed herein are considered for use with the present invention.
For example, microwave energy interacting components include foils that are thick enough to protect one or more selected parts of food from microwave energy (sometimes referred to as "protective components"). .. These protective ingredients are used in areas where foodstuffs tend to burn or dry during heating. Protective ingredients are formed from a variety of materials and have a variety of configurations, depending on the particular application in which the protective ingredient is used. Generally, the protective component is formed from a conductive, reflective metal or metal alloy, such as aluminum, copper, or stainless steel. Protective ingredients generally have a thickness of about 0.000285 inches to about 0.05 inches. In one embodiment, the protective ingredient has a thickness of about 0.0003 inches to about 0.03 inches. In another embodiment, the protective component has a thickness of about 0.00035 inches to about 0.020 inches, such as 0.016 inches.
As yet another example, microwave energy interacting components include segment foils disclosed in US Pat. Nos. 6,204,492, 6,433,322, 6,552,315, and 6,677,563, which are incorporated herein by reference. However, it is not limited to this. Although the segment foils are not continuous, the properly spaced grouping of these segments acts as a transfer component, directing microwave energy towards specific points in the food product. Such foils may be used in combination with browning and / or crispy finishing ingredients, such as susceptors.
Any microwave energy interacting component disclosed and / or considered herein is substantially continuous, i.e. virtually free of crevices or blockages, or, for example, transfers microwave energy. It becomes discontinuous by including one or more crevices or openings. The crevices or openings may be measured and / or placed to selectively heat specific areas of the food product. As mentioned above, the number, form, size and arrangement of crevices or openings are the type of components formed, the foodstuffs heated inside or above, the degree of desired protection, browning or crispness, Whether direct exposure to microwave energy is necessary or desirable for uniform heating of food, the need to control temperature changes in food due to direct heating, and the need for ventilation. It may vary depending on the particular application, such as the presence or absence or degree thereof, and many other factors.
It will also be appreciated that the opening may be a physical opening, or a pore in the material used to form the component, or a non-physical "opening". The non-physical aperture may be part of a component that is microwave inactive due to deactivation or vice versa, or is unresponsive to microwave energy. Thus, for example, the openings are part of the components formed except for the microwave energy interacting material, even if they are part of the components formed with the inactivated microwave energy interacting material. Good. While physical and non-physical openings allow the food to be heated directly by microwave energy, the physical openings also provide ventilation to release steam or other steam from the food.
It is also beneficial to form one or more dissociated or inert regions to prevent excessive heating or charring of the components. As an example, but not limited to, the panels 104a and 104b in the component 178 illustrated in FIG. 1C overlap to form a second main panel 104, as described below. When exposed to microwave energy, the concentration of heat by the overlapping panels is sufficient to burn the underlay, which in this case is the paperboard. Thus, for example, by excluding microwave energy interacting materials and forming these regions, or by deactivating microwave energy interacting materials in these regions, panels 104a and 104b. The overlapping site of one or both of the above can be configured to inactivate the microwave.
Furthermore, microwave energy is always effective on food parts that are not intended to be browned and / or crispy, or in areas that are browned and / or crispy without being lost in a heated environment. Microwave energies can be configured to be inactive in one or more panels, parts of panels, or parts of components so that they are centrally focused.
As mentioned above, any of the above elements and many other elements considered herein can be supported on the substrate. The substrate typically comprises an electrical insulator, such as, for example, a polymeric film or other polymeric material. The terms "polymer," "polymer film," and "polymer material" used herein refer to, for example, block, transplanted, irregular and modified copolymers, homopolymers such as tarpolymers, copolymers, and.

In another aspect, the thickness of the film is from about 45 to about 50 gauge. In yet another aspect, the thickness of the film is about 48 gauge. Examples of polymer films that may be suitable include, but are not limited to, polyolefins, polyesters, polyamides, polyimides, polysulfones, polyetherketones, cellophane, or any mixture thereof. Other non-conductive substrate materials can be used, such as paper or paper laminates, metals oxide, silicates, cellulose derivatives, or any mixture thereof.

(Covington, Georgia), BARRIAL OXPET from Toray Films (Front Royal, VA) and QU50 High Barrier Coated PET from Toray Films (Front Royal, VA) Including, but not limited to.
Polymer films can be selected to impart a variety of properties to the microwave interacting web, such as printability, thermal resistance or any other property. As a particular example, the polymeric film can be selected to provide a moisture barrier, an oxygen barrier or a combination thereof. The layer of such a barrier film can be formed from a polymer having barrier properties, or from any other barrier layer or coating, if desired. Suitable polymer films are ethylene vinyl alcohol, barrier nylon, polyvinylidene chloride, barrier fluoropolymer, nylon 6, nylon 6,6, co-extruded nylon 6 / EVOH / nylon 6, silicon oxide coated film, barrier polyethylene terephthalate, or Including, but not limited to, any mixture of these.

Additional examples are the BARRIALOX PET sold by Toray Films (Front Royal, VA) and the QU50 High Barrier Coated PET sold by Toray Films (Front Royal, VA) above.
Other barrier films are silicon oxide coated films, such as those sold by Sheldahl Films (Northfield, Minnesota). Thus, in one example, the susceptor may include a film such as polyethylene terephthalate, the film being coated with a layer of silicon oxide, and the silicon oxide having a structure in which ITO or other material is deposited. .. If necessary or desired, additional layers or coatings can be provided to prevent damage to each layer during processing.

Microwave energy interacting materials can be applied to the substrate in any suitable manner, and in some cases microwave energy interacting materials can be printed, extruded, sputtered, deposited, or deposited on the substrate. It is laminated. The microwave energy interacting material can be applied to the substrate in any pattern and using any technique to achieve the desired heating effect of the food. For example, microwave energy interacting materials can be provided as continuous or discontinuous layers or coatings, including circulars, loops, polygons, islands, squares, rectangles, octagons, and the like. Examples of various patterns and methods that may be suitable for use in the present invention are U.S. Pat. Nos. 6,765,182; 6,717,121; 6,677,563; 6,552,315; 6,455,827; 6,433,322; 6,410,290; 6,251,451; 6,204,492; 6,150,646; 6,114,679; 5,800,724; 5,759,418; 5,672,407; 5,628,921; 5,519,195; 5,420,517; 5,410,135; 5,354,973; 5,340,436; 5,266,386; 5,260,537; 5221,419; 5,213,902; 5,117,078; 5,039,364; 4,963,420; 4,936,935; 4,890,439; 4,775,771; 4,865,921; Incorporated herein. Although specific examples of patterns of microwave energy interacting materials are described herein, it should be understood that other patterns of microwave energy interacting materials are considered by the present invention.
Microwave interaction elements or microwave interaction webs are dimensionally stable microwave energy transmission supports (hereinafter "microwave transmission support", "micro" so as to form at least a portion of the components. Can be connected to or overlaid with a "wave interaction support" or "support" (called a support).
In some embodiments, for example, when fixed or semi-fixed components are formed, all or part of the support is formed at least partially from the paperboard material, which can be cut into blanks before use in the components. can do. For example, the support can be formed from paperboard with a base weight of about 60 to about 330 lbs / ream, for example about 80 to about 140 lbs / ream. Paperboard can generally have a thickness of about 6 to 30 mils, for example about 12 to about 28 mils. In one particular example, the paperboard has a thickness of about 12 mils. SUS commercially available from Graphic Packaging International<sup>(R)</sup>Any suitable paperboard can be used, such as a rugged bleached or rugged unbleached sulfate board, such as a board.
In another aspect, when forming more flexible components, the support is generally a paper or paper-based material with a base weight of about 15 to about 60 lbs / ream, for example about 20 to about 40 lbs / ream. Can be provided. In one particular example, the paper has a base weight of about 25 lbs / ream.
Optionally, one or more parts or sides of the various blanks or other components described or considered herein may be coated with varnish, clay or other material alone or in combination. .. For example, at least the sides of the support that form the outer surface of the component to be assembled can be coated with clay coat or other paint. The coating can then be printed with product advertisements, images, price codes or any other information or markings, or any combination thereof. The blank or component can then be overcoated with varnish to protect any information printed on the surface.
In addition, the blank or other component can be coated on one or both sides, for example with a moisture and / or oxygen barrier layer, as described above. According to the present invention, any suitable moisture and / or oxygen barrier material can be used. Examples of potentially suitable materials include, but are not limited to, polyvinylidene chloride, ethylene vinyl alcohol, DuPont DARTEK® nylon 6,6, and other materials referred to above.
Alternatively, or in addition, all of the blanks or other components of the invention may affect other properties such as absorbency, water repellency, opacity, color, printability, stiffness or cushioning. Can be coated or laminated with the following materials. For example, Absorbent Microwave Interactive Packaging is described by US Provisional Application No. 60 / 604,637 filed on August 25, 2004 and US Patent No. 11 / 211,854 filed on August 25, 2005, by Middleton et al. Both are incorporated by reference in their entirety.
It is understood that some combinations of elements and materials allow microwave interacting elements to have a gray or silver color that is visually distinguishable from the substrate or support. However, in some cases it may be desirable to provide a web or component with a single color and / or appearance. Such a web or component enhances the appearance to the consumer, for example solid colors, special patterns, especially if the consumer is accustomed to a package or container with certain visual attributes. be able to. Thus, for example, the present invention uses silver or gray tones to bond the microwave interacting elements to the substrate, to hide the presence of silver or gray tones of the microwave interacting elements. Use silver or gray tones to hide the presence of silver or gray tones of microwave interacting elements, use dark tones such as black tones to make color changes less noticeable Print on the metal-deposited sides of the web with silver or gray tones, with a suitable pattern in silver or gray ink or other unobtrusive colors to hide or obscure the presence of microwave interacting elements. Alternatively, printing the non-metallic sides of the web as a layer of solid color, or using other suitable techniques or combinations thereof can be considered.
Returning to the drawings, a number of procedures and steps can be used to form component 178 in accordance with the present invention. In one example, folding a blank 100 along fold lines 110, 112, 114 and 116 causes the ends 150 and 160 to meet each other, leading to tips 180 and 182 (Fig. 1B) and a cavity or inner space 184 between them (Fig. 1C). And 1D) to form a sleeve 178.
The first main panel 104a and the second main panel 104b form the second main panel 104, and the second main panel 104 is formed by the glued portions 162 and 174 that are at least partially obscured by the corresponding parts of the main panel 104b. Overlap to the required part so as to form. Thus, except for the overlapping portion of the panel 104a, FIG. 1A represents the outer surface 186 of the component 178 being formed. Similarly, the partial end panels 118a and 118b overlap to the part required to form the end panel 118, but the panel is substantially lenticular, with overlapping partial cutouts 122a and 122b. There is a slightly semi-circular cutout 122 formed. Further, the fold line portions 120a and 120b overlap as necessary to form an arch-shaped fold line 120. It is understood that in this aspect and other aspects of the invention, other shapes of end panels and cutouts are considered. For example, the end panel can be elliptical, rectangular, square, rhombic, trapezoidal, polygonal, or any other regular or irregular shape. The cutout can be circular, square, or any other regular or irregular shape.
The overlapping portions can be glued or joined to form a sleeve 178 with a first removable portion 140 and a second removable portion 142. The first subpanel 106 and the second subpanel 108 form facing side walls of the components, which can be gusseted by folding inward along fold lines 132 and 134 (FIG. 1C). And 1D). In this embodiment, the tabs 148 and 166 are not glued or affixed to the first main panel 104a. However, the tabs 148 and 166 can be detachably attached to the first main panel 104a, if desired.
To use the components, for example, food F is placed from the tip 180 or 182 and component 178 containing food F is placed in a microwave oven (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. In this and other aspects of the invention, any panel, such as the first main panel 102, the first main panel 104a or the second main panel 104b, may be contoured to a particular food product to be heated in. One or more folds, dividing lines, cut lines, cut folds, or other breaks along all or part of its length or width to adapt and bring Sucepta M closer to the surface of the food. It is considered that lines can be included. All steam generated during heating can be released from the sleeve openings 180 and 182 or through the openings 136 and 138.
After sufficiently heating the food, the user can remove the food F from the components. Alternatively, the end panels 118 and 124 can be folded toward the inside 184 of the sleeve 178 to form a component having an opening tip 180 and a closing tip 182 as shown in FIG. 1D. In this and other aspects of the invention, the end panels can be folded inward in any order. Thus, for example, the end panel 118 can be folded inward before the end panel 124 is folded inward. Alternatively, the end panel 124 can be folded inward before the end panel 118 is folded inward. In either configuration, component 178 can be placed upright so that the food is supported by end panels 118 and 124 and serves as the base of the container. This provides a convenient means of handling heated food F without problems.
When eating food F, component 178 may begin to interfere with the food F being eaten. If desired, the user can grab tab 148 and pull outward from component 178. By doing so, the removable site 140 begins to separate from the rest of the component 178 along the cleavage lines 152a, 152b and 144, as shown in FIG. 1E. Further pulling, as shown in FIG. 1F, the first removable portion 140 is completely separated from the component 178.
As food F is eaten further, component 178 may again begin to interfere with food F being eaten. If desired, the user can grab tab 166 and pull outward from component 178. By doing so, the removable site 142 begins to separate from the rest of the component 178 along the cleavage lines 170a, 170b and 146, as shown in FIG. 1F. Further pulling causes the second removable portion 142 to be completely separated (hidden) from the component 178, making it easier to remove the food F inside.
Although the detachable sites 140 and 142 have been described herein to be removed in the above order, panels 140 and 142 by grabbing both tabs 148 and 166 and cutting the panel along the cleavage line 146. It is understood that both can be removed at the same time. This may be useful, for example, when the user has eaten most of the food and needs to eat more food without removing the first removable portion 140.
FIG. 2A represents another exemplary blank 200 according to various aspects of the invention. In this embodiment, the blank 200 includes a plurality of joined panels including a main panel 202, a first main panel 204a, a second main panel 204b, a first subpanel 206, and a second subpanel 208. .. The first sub-panel 206 is joined to the first main panel 204a along the vertical fold line 210. The main panel 202 is joined to the first sub-panel 206 along the vertical fold line 212. The second sub-panel 208 joins to the main panel 202 along the longitudinal fold line 214. The second main panel 204b is joined to the second sub-panel 208 along the vertical fold line 216. In this embodiment, the sub-panels 206 and 208 are substantially equal in length, as indicated by L2. In addition, the polygonal lines 210, 212, 214 and 216 are substantially parallel and substantially equal in length L2. However, other lengths and configurations are also considered.
Blank 200 includes partial end panels 218a and 218b and joins panels 204a and 204b along the respective fold lines 220a and 220b, respectively. The partial end panels 218a and 218b each contain a partial cutout of 222a and 222b, respectively. The blank 200 further includes an end panel 224 joined to the main panel 202 along the fold line 226. In this embodiment, the end panel 224 has a substantially lenticular shape. However, the panel 224 can have any suitable shape.
The first subpanel 206 and the second subpanel 208 include longitudinal fold lines 228 and 230 that are substantially centered and extend along their length L2, respectively. Optionally, one or both of the first subpanel 206 and the second subpanel 208 include openings 232 and 234, respectively. In the example shown in FIG. 2A, the opening 232 has a substantially circular shape and is substantially between the polygonal lines 210 and 212. Similarly, the opening 234 has a substantially circular shape and is substantially between the polygonal lines 214 and 216. However, as mentioned above, the number, shape and location of such openings can be varied depending on the particular application.
Subsequently referring to FIG. 2A, the blank 200 includes a removable portion 236 formed extending from at least each of the panels 202, 204a, 204b, 206 and 208. The removable site 236 is joined to the rest of the panels 202, 204a and 204b in this embodiment along the transverse line of the split or cleavage line 238 interrupted by openings 232 and 234. Although the exemplary blank 200 of FIG. 2B contains only one removable portion 236, it is understood that any number of such panels and any configuration of such panels can be used as desired.
Detachable part 236 includes an extension or tab 240 that partially defines the end 242. In this embodiment, the tab 240 has a slightly arched shape. However, it is understood that the extension can have any shape as needed or desired. The cleavage line 244a extends in the direction of the end 248 from the first tip 246a of the extension 240 and can be in contact with it. The cleavage line 244b can extend and contact the transverse cleavage line 238 from the second tip 246b of the tab 240. In this embodiment, the cleavage lines 244a and 244b are arranged relative to the extension 240 such that the cleavage lines 244a, tab 240 and cleavage line 244b are slightly arched in shape. However, it should be understood that such cleavage lines can have any suitable shape and may or may not correspond to the shape of the tab. Thus, for example, the tab 240 may have a slightly arched shape, but the cleavage line portions 244a and 244b may have parallel lines, zigzags or any other shape. Cleavage lines 244a and 244b, together with tab 240, facilitate the separation of the first removable site 236, as described below.
The removable portion 236 also includes a cutout 248 that partially defines the end 250. In this embodiment, the shape of the cutout 248 is also slightly arched. Like tabs, cutouts can have any suitable shape, as described above, but not limited to these, as needed or desired, and correspond to the shape or dimensions of the tab. Or can not. The removable portion 236 also includes a glued portion 252 adjacent to the cutout 248 and is defined by a periphery 254. In the blank 200 shown in FIG. 2A, the shape of the glued portion 252 is arch or bridge. However, it is understood that the glued portion can have any shape if desired or desired.
If desired, the susceptor M can cover at least a portion of the blank 200 (not shown in the figure of FIG. 2A, which illustrates the sides of the blank forming the outer surface of the component), as can be seen in FIGS. 2B and 2C. At least a portion of the inner surface of the component 256 formed from it can be formed. However, it is considered that other microwave energy interacting elements as described herein are used in the present invention.
A number of steps and procedures according to the invention can be used to form the sleeve or other component 256. In one example, when the blank 200 is folded along the fold lines 210, 212, 214 and 216, the ends 242 and 250 fit together and have tips 258 and 260 with a cavity or inner space 262 in between. Form 256 (Fig. 2B).
The first and second main panels 204a and 204b overlap to the part necessary to form the second main panel 204 with a glued portion 252 that is at least partially hidden by the second main panel 204b. Thus, except for the overlapping portion of the main panel 204a, FIG. 2A represents the outer surface 264 of the component 256 formed. Similarly, the partial end panels 218a and 218b overlap the parts needed to form the edge panel 218, but this panel is substantially lenticular and is formed by overlapping partial cutouts 222a and 222b. There is a slightly semi-circular cutout 222. Further, the fold line portions 220a and 220b overlap with each other as necessary to form the arch-shaped fold line 220. As mentioned above, other shapes of end panels and cutouts are considered.
Then, the overlapping portions are glued or joined so as to form a sleeve 256 having the removable portion 236 including the removable portion 236 of the blank 200. In this configuration, the first subpanel 206 and the second subpanel 208 form the facing sides of the component 256, which, as shown in FIG. 2B, along the fold lines 228 and 230. You can attach a gusset by folding it inward. In this embodiment, the extension or tab 240 is not glued or affixed to the panel 204a. However, it is understood that the tab 240 can be detachably attached to the panel 204a if desired.
To use this component, for example, food F is placed through the opening tip 258 or 260 and the component 256 containing food F is placed in a microwave oven (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. All steam generated during heating can be released from the sleeve openings 258 and 260, or from openings 232 and 234.
After sufficiently heating the food, the user can remove the food F from the components. Alternatively, the end panels 218 and 224 can be folded towards the inside 262 of the sleeve 256 to form a component or container with an opening tip 258 and a closing tip 260 (FIG. 2C). In this way, the component 256 can be placed upright so that the food is supported by the end panels 218 and 224 and serves as the base of the container.
When eating food (hidden), component 256 may begin to interfere with eating food. If desired, the user can grab the tab or extension 240 and pull it out of component 256, as shown in Figure 2C. The removable site 236 then begins to separate from the rest of the component 256 along the cleavage lines 244a, 244b and 238. When pulled further, the removable portion 236 is completely separated from the component 256. As a result, food becomes easier to eat.
FIG. 3A shows another exemplary blank 300. Blank 300 includes a plurality of joined panels, including a main panel 302, a first main panel 304a, a second main panel 304b, a first subpanel 306, and a second subpanel 308. The first sub-panel 306 joins the first main panel 304a along the longitudinal fold line 310. The main panel 302 is joined to the first sub-panel 306 along the vertical fold line 312. The second subpanel 308 joins the main panel 302 along the longitudinal fold line 314. The second main panel 304b is joined to the second sub-panel 308 along the vertical fold line 316. In this embodiment, the sub-panels 306 and 308 are substantially equal in length L3. In addition, the polygonal lines 310, 312, 314 and 316 are substantially parallel and substantially equal in length L3. However, other lengths and configurations are also considered.
The blank 300 includes partial end panels 318a and 318b, which are joined to panels 304a and 304b along the curved line portions 320a and 320b, respectively. Optionally, the partial end panels 318a and 318b each include a partial cutout of 322a and 322b, respectively. The blank 300 includes an end panel 324 joined to the main panel 302 along a slightly arched fold line 326. In this embodiment, the end panel 324 has a substantially lenticular shape. However, it is considered that the end panel can have any suitable shape.
The first subpanel 306 and the second subpanel 308 include longitudinal fold lines 328 and 330, which are substantially centered and extend along their length L3, respectively. Optionally, one or both of the first subpanel 306 and the second subpanel 308 include openings 332 and 334, respectively. In the example shown in FIG. 3A, the opening 332 has a substantially circular shape and is substantially between the polygonal lines 310 and 312. The opening 334 has a substantially circular shape and is substantially between the polygonal lines 314 and 316. However, as mentioned above, the number, shape and location of such openings can be varied depending on the particular application.
Subsequently referring to FIG. 3A, the blank 300 includes a removable portion 336 formed extending from at least each of the panels 302, 304a, 304b, 306 and 308. The removable site 336 joins the rest of the panels 302, 304a and 304b along the transverse cleavage line of the transverse cleavage line 338. The exemplary blank 300 of FIG. 3A contains only one removable part 236, but it is understood that any number of such parts or panels and any configuration of such panels can be used as desired. To.
Detachable part 336 includes a slightly triangular tab 340 extending from the main panel 302. In this embodiment, the tab 340 comprises at least a portion of the subpanel 308 and is defined by a slightly arched or V-shaped cut line 344. However, it is understood that the location and shape of the tab 340 can be changed according to the particular application. The cleavage line 342a extends in the direction of the end 346 from the first tip 344a of the cut line 344 and can be in contact with it. The cleavage line 342b can extend from the second tip 344b of the cut line 344 in the direction of the transverse cleavage line 338 and be in contact with it. In this embodiment, the cleavage lines 342a and 342b are arranged relative to the tab 340 such that the cleavage lines 342a, 344 and 342b are slightly V-shaped. However, it is understood that such cleavage lines can have any suitable shape and may or may not correspond to the shape of the tab. Thus, for example, the shape of the tab 340 is slightly triangular, but the cleavage line portions 342a and 342b can be parallel lines, zigzags or any other shape. The cleavage line portions 342a and 342b, together with the tab 340, facilitate the separation of the first detachable site 336, as described below.
If desired, the susceptor M can cover at least a portion of the blank 300 (not shown in the figure of FIG. 3A, which illustrates the sides of the blank forming the outer surface of the component), as can be seen in FIGS. 3B-3F. In addition, at least a portion of the inner surface of the component 352 formed from it can be formed. However, it is considered that other microwave energy interacting elements as described herein are used in the present invention.
A number of steps according to the invention can be used to form a sleeve or other component 352. In one example, when the blank 300 is folded along fold lines 310, 312, 314 and 316, as shown in Figure 3B, the ends 348 and 350 fit together and the two opening tips 354, respectively. And 356, and a sleeve 352 with a cavity or inner space 358 between them. The first and second main panels 304a and 304b overlap the parts required to form the second main panel 304, and the partial end panels 318a and 318b are the parts required to form the end panel 318. Overlap, the fold lines 320a and 320b overlap the parts necessary to form the fold line 320, and the partial cutouts 322a and 322b overlap the parts necessary to form the cutout 322. In this embodiment, the shape of the cutout 322 is slightly semicircular. However, it is understood that many other shapes are considered.
The overlapping portions are glued or joined to form a sleeve 352 that includes a removable portion 336 that includes a removable portion 336 of the blank 300. The first subpanel 306 and the second subpanel 308 form the facing sides of the components, which can be gusseted by folding inward along the fold lines 328 and 330 (Fig. 3D). ..
To use this component, food (hidden) is placed through the opening tip 354 or 356 and the component 352 containing the food is placed in a microwave oven (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. All steam generated during heating can be released from the opening tips 354 and 356 of the sleeve or from the openings 332 and 334.
After the food has been sufficiently heated, the user can remove the food from the components or fold the end panels 318 and 324 towards the inside 358 of the sleeve, as shown in Figure 3C. A container 352 with an open tip 354 and a closed tip 356 can be formed. The component 352 can then be placed upright with the food supported by the inwardly folded and stacked end panels 318 and 324, which serve as the base of the container. This provides a convenient means of handling food without the fear of touching the surface of the heated food.
Refer to Figure 3D-3F, when eating food, the components begin to get in the way of the food you are eating. If desired, the user can grab the tab 340 and pull it out of the component. The removable site 336 then begins to separate from the rest of the component along the cleavage lines 342a, 342b and 338. When pulled further, the removable portion 336 is completely separated from the components, making food easier to eat.
FIG. 4A illustrates yet another typical blank 400 according to the present invention.

However, as mentioned above, the number, shape and location of such openings can be varied depending on the particular application.
Subsequently referring to FIG. 4A, the blank 400 includes a removable portion 438 formed extending from at least each of the panels 402, 404a, 404b, 406 and 408. The removable site 438 joins the rest of the panels 402, 404a and 404b along the transverse cleavage line of the transverse cleavage line 440. The exemplary blank 400 of FIG. 4 contains only one removable portion 438, but it is understood that any number of such parts or panels and any configuration of such panels can be used as desired. To.
Detachable part 438 includes a slightly elongated cutout 442 that ends near fold line 432 in the first main panel 402 and the second subpanel 408. The portion of the cutout 442 of the first main panel 402 has a slightly semicircular shape and has an arched grasping end 444. The portion of the cutout 442 of the second subpanel 408 is generally rectangular or square in shape. The cleavage line 446a can extend from the first end 448a of the grasping end 444 to the end 450 and be in contact with it. The cleavage line 446b extends from the second end 448b of the grasping end 444 to the walk of the transverse cleavage line 440 and is substantially accessible. Cleavage lines 446a and 446b, together with the grasping end 444, facilitate the separation of the removable site 438 when a blank is formed on the sleeve or container (hidden).
If desired, the susceptor M can cover at least a portion of the blank 400 (not shown in the figure of FIG. 4A, which illustrates the sides of the blank forming the outer surface of the component), as can be seen in FIGS. 4B and 4C. At least a portion of the inner surface of the component 452 formed from it can be formed.
A number of steps according to the invention can be used to form a sleeve or other component 452. In one example, when the blank 400 is folded along fold lines 410, 412, 414 and 416, as shown in Figure 4B, the ends 454 and 456 fit together and the two opening tips 458, respectively. And 460, and a sleeve 452 with a cavity or inner space 462 between them. The first and second main panels 404a and 404b overlap the parts needed to form the second main panel 404, and the partial end panels 418a and 418b have the parts needed to form the end panel 418. Overlapping, the fold lines 420a and 420b overlap with each other as necessary to form the fold line 420. The overlapping portions can be glued or joined to form a sleeve 452 that includes a removable portion 438 that includes a removable portion 438 of the blank 400. The first subpanel 406 and the second subpanel 408 form facing side walls of the components, which can be gusseted by folding inward along fold lines 430 and 432.
To use this component 452, for example, food (hidden) is placed through the opening tip 458 or 460 and the component containing the food is placed in a microwave oven (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. All steam generated during heating can be released from the sleeve openings 458 and 460 or from openings 434 and 436.
After sufficiently heating the food, the user can remove the food from the sleeve 452. Alternatively, the end panels 418 and 424 can be folded towards the inside 462 of the sleeve 452 to form a component with an opening tip 458 and a closing tip 460, as shown in FIG. 4C. If desired, the panel can be fixed in place by inserting the fixing function 422 into the receiving slit 428 (not shown in Figure 4C). When placed face up, the end panels 418 and 424 serve as the base for container 452 to support the food (hidden) within it.
When eating food, the components may begin to interfere with eating the food. If desired, the user can insert a finger or other tool into the cutout 442 along the grip end 444 to begin separating the removable portion 438 from the rest of the component. The removable site 438 then begins to separate from the rest of the component along the cleavage lines 446a, 446b and 440. Further pulling makes the removable part 438 completely separate from the components, making food easier to eat, as shown for Figure 3D-3F.
FIG. 5A illustrates yet another typical blank 500 according to the present invention. The blank in FIG. 5A is similar to the blank in FIG. 4A, except that the cutout 542 is in the second subpanel 508 and is substantially between the fold lines 514 and 532. The shape of the cutout 542 is approximately square or rectangular, with a substantially straight grasping end 544 that is substantially straight with the polygonal line 514.
If desired, the susceptor M can cover at least a portion of the blank 500 (not shown in the figure of FIG. 5A, which illustrates the sides of the blank forming the outer surface of the component), as can be seen in FIG. 5B. At least a portion of the inner surface of the component 552 formed from it can be formed.
From the blank 500, it is possible to form sleeves (hidden) for heating, browning, and / or crispy food in the microwave. The sleeve can then be transformed into a container to support the food when it is eaten, as shown in Figure 5B. The user can insert a finger or other tool into the cutout 542 along the grip end 544 to begin separating the removable portion 538 from the rest of the component 552. The removable site 538 then initiates separation from the rest of the component along the cleavage lines 546a, 546b and 540. Further pulling causes the removable portion 538 to be completely separated from the components, making the food inside easier to eat, as shown in connection with Figure 3D-3F.

To use this component, food (hidden) is placed through the opening tip 848 or 850 and the sleeve 842 containing the food is placed in the microwave (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. All steam generated during heating can be released from the sleeve openings 848 and 850, or from openings 832 and 834.
After the food has been sufficiently heated, the user can remove the food from the components. Alternatively, the end panels 818 and 824 can be folded towards the inside 852 of the sleeve 842 to form a container 842 with an open tip 842 and a closed tip 850, as shown in FIG. 8D. The component 842 can then be placed facing up so that the end panels 818 and 824 serve as the basis for supporting the food. This provides a convenient means of handling and carrying the heated food without touching the surface of the heated food.
Referring to FIG. 8E-8G, when eating food (hidden), the user can grab the tab 840 and initiate the separation of the cleavage strip 836 from the rest of the component 842. With further pull, the cleavage strip 836 continues to separate from component 842 until the cleavage strip 836 reaches the end point, allowing the user to eat food as needed or as desired.

The first and second main panels 904a and 904b include aligned cross-fold sections 928a and 928b, respectively. The fold line 928a passes between the end 930 and the cleavage line 910 and is substantially vertical. The fold line 928b passes between the end 932 and the cleavage line 916 and is substantially vertical. Similarly, the first main panel includes a substantially vertical transverse fold line 934 passing between the rift lines 912 and the rift line 914. In the example of Figure 9A, the polygonal lines 928a, 934 and 928b are substantially in line. However, it is understood that the polygonal line 934 may not be in line with the parts 928a and 928b if necessary or desired. In addition, any of 928a, 928b and 934 can be a cleavage line or other breaking line if necessary or desired.
The first subpanel 906 and the second subpanel 908 include polygonal lines 936 and 938, which are substantially centered and extend along their length L12, respectively. The first subpanel 906 and the second subpanel 908 are such that the overall length L12 of the subpanels 906 and 908, including the extensions 940 and 942, respectively, is longer than the panels 902, 904a and 904b ( Also includes extensions or tabs 940 and 942 extending beyond the panels 902, 904a and 904b) (measured at the longest point). In this embodiment, the tabs 940 and 942 have a slightly semicircular or circular shape. However, many other shapes are considered here. For example, each tab or extension can independently have a triangular, square, rectangular or any other regular or irregular shape, if desired.
Optionally, one or both of the first subpanel 906 and the second subpanel 908 include openings 944 and 946, respectively. In the example shown in FIG. 9A, the opening 944 has a substantially circular shape and passes substantially between the cleavage lines 910 and 912. Similarly, the opening 946 has a substantially circular shape and passes substantially between the cleavage lines 914 and 916.

With reference to FIG. 9B-9E, the sequence of steps according to the invention can be used to form a sleeve or other component 948. In one example, when the blank 900 is folded along the fold lines 910, 912, 914 and 916, the ends 930 and 932 fit together into two tips 950 and 952 and a cavity or inner space 954 between them. Form a sleeve 948 with. The first and second main panels 904a and 904b overlap with each other as necessary to form the second main panel 904. The fold line portions 928a and 928b overlap with each other as necessary to form the fold line 928. The partial end panels 918a and 918b overlap with each other as necessary to form the end panel 918. The fold line portions 920a and 920b overlap with each other as necessary to form an arch-shaped fold line (hidden). Partial cutouts 922a and 922b overlap the parts needed to form a cutout (hidden).
The overlapping portions are joined by gluing or other methods. The first subpanel 906 and the second subpanel 908 form the facing side walls of the component 948, which can be gusseted by folding inward along the fold lines 936 and 938, respectively. ..
To use the components, for example, food F is placed from the tip 950 or 952 and the component 948 containing the food is placed in a microwave oven (hidden) and heated. When the food is heated, Sucepta M enhances the browning and / or crispy finishing effect on the surface of the food. The steam generated during heating can be released from the opening tips 950 and 952 of the sleeve, or the openings 944 and 946.
After the food has been sufficiently heated, the user can remove the food from the components. Alternatively, as described above, the end panels 918 and 924 are folded towards the inner 954 of the component 948 to form a component with an open tip 950 and a closed tip 952, as shown in FIG. 9C. Can be done. The component 948 can then be placed facing up so that the inwardly folded end panels 918 and 924 serve as a base to support the food.
Referring to Figures 9D and 9E, when eating food F, the user grabs one or both of tabs 940 and 942 and follows the cleavage lines 910 and 912 and / or 914 and 916, respectively. From the rest of the component 948, the separation of the corresponding subpanels 906 and 908 can be started. In this embodiment, the separation of subpanels 906 and 908 from the components is interrupted when the openings 944 and 946 are reached. Cleavage can be initiated again if further separation is desired. As shown in Figure 9E, one or both of the main panels 902 and 904 should be at their respective polygonal lines 928 and / or 934 to make the food contained within component 948 easier to eat. Can be folded along. If one or both of the fold lines 928 and 934 are cleavage lines, such folds can be removed if desired. As is clear from Figure 9E, the components facilitate the retrieval of the food being eaten.
In this embodiment, it can be said that one or both of the first subpanel 906 and the second subpanel 906 comprises removable parts of the components. However, since the various panels are separated along the cleavage line adjacent to such panels, one or both of the first main panel 902 and the second main panel 904 may have components attached or detached. Understand that it can be considered a possible site. Thus, in certain embodiments of the invention, the removable sites can be characterized by a number of different techniques without limitation.

In the example shown here, the components have a slightly rectangular shape and are ideal for heating sandwiches and pastries for breakfast, for example. However, it is understood that in this aspect and other aspects of the invention described or considered herein, a number of suitable shapes and configurations can be used to form the various panels and thus the components. To do. Examples of other shapes included herein include, but are not limited to, polygons, circles, oval (oval), cylinders, triangular prisms, spheres, polyhedra, and ellipsoids. The shape of each panel can be largely determined by the shape of the food, so different packages vary, for example sandwiches, pizzas, french fries, soft pretzels, bite pizzas, cheese sticks, pastries, breads, etc. Please understand that it is considered in food. The components can be flexible, semi-fixed, and fixed. Alternatively, it can include different components with different flexibility.

Although certain embodiments of the invention have been described with certain details, one of ordinary skill in the art can make numerous modifications to the disclosed embodiments without departing from the spirit or scope of the invention. All directional references (eg, up, down, up, down, left, right, left, right, top, bottom, up, down, vertical, horizontal, clockwise and counterclockwise, etc.) It is used solely for identification purposes to aid the reader's understanding of the various embodiments of the invention and is not particularly limited with respect to the location, orientation or use of the invention unless otherwise stated in the claims. Absent. Join references (eg, join, attach, connect, connect, etc.) are broadly interpreted and can include intermediate members between the connections of the elements and relative movements between the elements. As such, connection references do not necessarily imply that the two elements are directly connected and in a fixed relationship with each other.
In each of the various blanks and trays described and considered herein, the "folding line" is any substantially non-straight line, but a softened linearity that facilitates folding along it. I want to be understood. Although not intended to narrow the scope of the present invention, more specifically, the fold line is a recess in the material along the desired softening line, a notch extending partially in the material along the desired softening line. And / or with a series of cuts that extend partially and / or completely to the material along the desired softening line, or with a blunt crease knife that creates any combination of these functions. It can be a dividing line such as a formed line.
For example, some conventional cleavage lines are in the form of a series of cuts that penetrate the material completely, typically with a V-shaped cut (eg, for example) to temporarily connect the material along the tear line. , A piece of material, such as a small bridge), slightly separated from the adjacent cut so that it is defined between the adjacent cuts. The V-shaped cut is cut during cleavage along the cleavage line. A cleavage line including such a V-shaped cut can also be called a cut line because the V-shaped cut is typically a relatively small proportion of the target line. Alternatively, the cut line can be omitted from such a cut line.
In addition, various exemplary blanks and components include polygonal lines, cleavage lines, dividing lines, cut lines, kiss cut lines, and, for example, from one particular panel to another, from one end to another. , Or any combination thereof, indicated and described herein as having other lines that extend from one particular function to another. However, it should be understood that such lines do not necessarily extend between such functions in an accurate manner. Alternatively, such lines may generally extend between various functions as needed to achieve the purpose of such lines. For example, if a particular cleavage line is shown to extend from one end of the blank to another end of the blank, the cleavage line is completely on one or both of these ends. There is no need to extend it. Rather, the tear wire is at the end so that the removable strip, panel, or portion can be manually separated from the blank or component without causing unwanted damage to the blank or component. It is necessary to extend it to a place close enough.
That is, one of ordinary skill in the art will readily appreciate in the above detailed description of the present invention that the present invention can be tolerated for a wide range of practicalities and uses.
