Tamper-Evident slider bag

[0001] (Technical field to which the invention belongs) The present invention relates generally to recloseable plastic bags, or more precisely to recloseable plastic bags having a tampa-evidence structure (a structure that leaves a trace of opening). In one embodiment, the plastic bag is fitted with a zipper with a slider so that the zipper can be opened and closed using the slider, and the tamper evidence structure initially puts the slider in the closed position on the zipper. It holds and allows the slider to move from the closed position to the open position on the zipper when the tamper evidence structure is removed or broken. In another embodiment, the tampa-evidence structure initially holds the mouth of the plastic bag in a folded state so that when the tampa-evidence structure is removed or broken, the mouth is widened. [0002] (Background of invention) The form of recloseable plastic bag disclosed in US Pat. No. 5,067,208 includes a zipper that opens and closes by moving a slider attached to the zipper. Bags with sliders have been popular over the last few years, thanks to the ease of operation of the sliders. So far, the main market for slidable bags has been consumers who buy packaging bags, which are empty slidable bags, and pack various products at home into the slidded bags. However, as slider bags have become more popular, product manufacturers have begun to take an interest in packaging food and non-food products in slider bags for sale to consumers. A bag with a slider is very convenient, especially for consumers who buy a bag full of products, even though it is a product that is used only a little at a time. There are almost endless products for which a bag with a slider is useful. The consumer first opens the slider bag, uses a portion of the product, and then easily recloses the slider bag. Sliding bags are especially preferred over general bags, which are easy to use and allow one-time opening and are more difficult to open and reclose. When opening a one-time openable bag, for example, the consumer tears the bag to open it, requires tools such as scissors to open it easily, and when reclosing it, it is usually in the bag. It requires a separate tightening mechanism, such as a clip, string, or tape, to wrap and close the top and keep the bag closed. [0003] The problem with plastic bags with sliders is that when such bags are packed with food or non-food and pre-wrapped, the contents of the plastic bags are easily tampered with before they are purchased by consumers (hereinafter referred to as "unfair interference"). It means that there is a risk. To prevent these undue interferences, the slided bag has been equipped with the tampa evidence structure of the form disclosed in US Pat. Nos. 5,669,715, 5,713,669, and 5,775,812. Such a tamper evidence structure can provide evidence of unfair interference when the bag is opened, but bag manufacturers such as the assignees of the above patents have introduced new bag structures to enhance the functionality of the bag. We are continuing our efforts to develop. [0004] (Outline of the invention) For this purpose, the present invention provides a plastic bag comprising a first body panel and a second body panel facing the first body panel, which are firmly joined to each other by a pair of side sides and a bottom connecting the pair of side sides to each other. provide. The bag is provided with a recloseable zipper that extends along the mouth formed on the opposite side of the sealed bottom of the plastic bag. It is desirable that the zipper does not have an upper pulling flange that can be grabbed to accommodate the slider and prevent operation of the zipper without the slider. The slider is slidably mounted on the zipper so that it can move between the closed and open positions. If the slider is in the closed position, the zipper is closed. The zipper opens as the slider moves towards the open position. The bag optionally has an end at the opposite end of the zipper to prevent the slider from passing over the end of the zipper. The bag is provided with a tamper evidence structure to provide evidence of unfair interference with the plastic bag. [0005] In one embodiment, the tampa-evidence structure initially holds the slider in the closed position, allowing the slider to move from the closed position to the open position when the tampa-evidence structure is removed or broken. .. Tampa evidence structures come in a variety of forms, for example, covering or adjacent to a slider in a closed position, glued to a bag to hold the member in place, or hooked. Adjacent to a removable cardboard, paper, or plastic member, a hole in the slider, or a slider in a closed position that is, is frictionally fitted, or is otherwise connected. A removable flexible member that extends through a hole in the zipper, and a slider so that the shoulder of the slider is initially engaged with the stepped member and disengaged when the stepped member is removed. A removable stepped holding member that is detachably attached to one of the bag body panels near the closed position, a latch that is connected to the end and is releasably engaged with the slider in the closed position. A removable U-shaped latch that is connected to the slider and is releasably engaged to the end when the slider is in the closed position, or extends through a slot in the slider in the closed position and cuts into the zipper. Members and the like. [0006] The tampa evidence structure initially holds the slider in the closed position. Therefore, without an upper flange that can be grabbed, it is difficult to grab and open the zipper by hand without using a slider, making it difficult to access the inside of the bag before removing or breaking the tampa evidence structure. Once the tampa evidence structure has been removed or broken, the slider can be used to open the zipper to access the contents of the bag. [0007] In another embodiment, the tampa-evidence structure initially holds the mouth of the plastic bag in a folded state so that the mouth can be opened when the tampa-evidence structure is removed or broken. The tamper evidence structure can be used for both slidable and non-slider bags and can take a variety of forms, such as spot seals that detachably seal both ends of the folded mouth to both ends of the bag. A spot seal that detachably seals the inner panel of the folded mouth to the adjacent bag panel, or a removable flexible member that passes through the folded mouth and the adjacent unfolded portion of the bag. Alternatively, one or more stickers (adhesive strips) that adhere the folded mouth to the adjacent unfolded portion of the bag, the above combinations, and the like can be mentioned. If a flexible member or sticker is employed and the plastic bag has a slider for manipulating the zipper, the flexible member or sticker has its mouth folded until the flexible member or sticker is removed from the bag. It is strategically placed to perform two functions: a function to hold the slider in position and a function to prevent the slider from moving from the closed position. [0008] The tampa-evidence structure of the present invention does not have to be a tamper-proof packaging, but is particularly useful for non-food products and certain food products where tamper-resistant packaging is desirable. To the extent, it effectively prevents the contents of the bag from being tampered with. [0009] (Detailed description of preferred embodiments) Other objects and advantages of the present invention will become apparent by reading the detailed description below and referring to the drawings. [0010] Various modifications and changes can be made to the present invention, but for the sake of explanation, specific examples will be illustrated and described in detail. However, it is not intended to limit the invention to the particular embodiments disclosed herein, but rather all alternatives, modifications and equivalents within the spirit and scope of the invention as defined in the claims. It should be understood as included in the present invention. [0011] FIG. 1 comprises a first body panel 12 and a second body panel 14 facing each other, which are firmly joined to each other by a pair of side sides 16 and 18 and a bottom 20 connecting the pair of side sides 16 and 18 to each other. A plastic bag 10 with a retractable slider is shown. The bag is provided with a recloseable zipper 22 that extends along the mouth formed on the opposite side of the closed bottom 20 of the plastic bag. [0012] As shown in FIG. 3, the zipper 22 has a male orbit and a female orbit. The male orbit includes a male shape portion 24 and a first hanging fin or flange 26 extending downward from the male shape portion 24. Similarly, the female orbit includes a female shape portion 28 and a second hanging fin or flange 30 extending downward from the female shape portion 28. The first and second fins 26 and 30 are heat welded to the inner surfaces of the first and second main body panels 12 and 14, respectively. Instead, the zipper 22 is extruded together with the body panels 12 and 14 so that the first fins 26 are integrally molded with the first body panel 12 and the second fins 30 are integrally molded with the second body panel 14. You can also do it. To keep the contents of the bag airtight, the first and second fins 26, 30 are joined together along the cut line at the bottom edge, effectively creating a single tampa evidence continuous fin. .. If the fins are joined to each other, the fins must be separated from each other along the cut line in order to access the contents of the bag. More information on the fins being joined can be found in US Patent Application No. 08 / 950,535, filed October 15, 1997, entitled "Recloseable Fastener Strips with Tampa Evidence Structure". The whole is incorporated here as a reference. [0013] To make it easier to open the plastic bag, a slider 32 is slidably attached to the zipper 22 so that it can move between the closed and open positions. As shown in FIG. 1, when the slider 32 is in the closed position, the male shape portion 24 and the female shape portion 28 are connected to each other. When the slider 32 is moved from the closed position to the open position (FIG. 2) in FIG. 1, the male shape portion 24 and the female shape portion 28 are separated from each other, and the user can access the inside of the plastic bag. .. It is desirable that the zipper 22 does not have a grippable upper pull flange that extends upward from the shaped portions 24 and 28 so that the slider 32 can be easily assembled and moved along the zipper 22. Without such an upper pull flange, the user can be prevented from opening and closing the zipper 22 without using the slider 32. [0014] Termination clamps 34 are provided on opposite ends of the zipper 22. Each termination clamp 34 includes a strap member that covers the top of the zipper 22. In order to attach the strap to the zipper 22, a rivet-shaped member that penetrates the bag material and reaches the common opening at the other end of the strap is provided at one end of the strap. The end clamp 34 is hung on the shape during normal use of the plastic bag and as a stopper for the end of the zipper 22 to prevent the slider 32 from passing through the end of the zipper 22. It fulfills two functions of holding the male shape portion 24 and the female shape portion 28 together in order to resist the force. Further details regarding the structure and operation of the slider 32 and the termination clamp 34 can be found in US Pat. No. 5,067,208, granted to Herrington Jr. et al., Which is hereby incorporated by reference in its entirety. Termination clamp 34 is illustrated for illustration purposes only and may be in other forms known in the art, such as US Pat. Nos. 5,482,375, 5,448,807, 5,442,837, 5,405,478, 5,161,286. Nos. 5,131,121, 5,088,971 and those disclosed in U.S. Patent Application No. 08 / 698,923, entitled "Terminal Posts for Plastic Zipper" filed August 16, 1996. The whole is incorporated here as a reference. [0015] The bag is fitted with a tampa evidence structure to leave evidence of tampering with the plastic bag. In the embodiments shown in FIGS. 4a-d to 16a-d, the tampa-evidence structure initially holds the slider 32 in the closed position (FIG. 1) and then from the closed position when the tampa-evidence structure is removed or broken. Allows movement towards the open position (Fig. 2). Without an upper flange that can be grabbed, it would be difficult to grab and open the zipper 22 by hand without using the slider 32, so it is difficult to access the inside of the bag before removing or breaking the tampa evidence structure. difficult. Tampa evidence structures can take various forms and are discussed below in relation to Figures 4a-d to 16a-d. [0016] In FIGS. 4a-d, the tamper evidence structure of the partially removable adhesive label 40 is adjacent to the narrow closed end 32a of the slider 32 when the slider 32 is in the closed position on the zipper 22. Shown in morphology. The opposite ends 40a and 40b of the label 40 are permanently glued to the outer surfaces of the opposite bag body panels 12 and 14, while the middle part 40c of the label 40 is removable to each end 40a and 40b along the perforations. Is connected to. One or both ends of each perforation line are provided with cuts along the perforation line to facilitate tearing. The intermediate portion 40c is either not glued to the bag or is stripped off. As shown in FIGS. 4a and 4c, the label 40 extends across the zipper 22 so as to block the movement of the slider 32 from the closed position before removal. To move the slider 32 and gain access to the inside of the bag, the user grabs a portion 40c of label 40 that extends across the zipper 22 and ends this portion 40c, as shown in FIGS. 4b and 4d. Separate from parts 40a and 40b. The ends 40a and 40b remaining on the bag provide evidence of unjustified interference. In another embodiment, the label 40 is not provided with perforations and is removed using a cutting tool such as scissors or a knife. [0017] In FIGS. 5a-d, the tamper evidence structure is a conventional plastic price tag pin 50 that extends through a hole 52 that penetrates the slider 32 and the zipper 22 when the slider 32 is in the closed position on the zipper 22. It is shown in the form of a flexible member such as. The price tag pin 50 is provided with a pair of stoppers 54 and 56 at opposite ends in order to keep the pin 50 in place. Since the price tag pin 50 is secured to the zipper 22, the slider 32 cannot be moved from the closed position until the price tag pin 50 is separated from the bag as shown in FIGS. 5b and 5d. Instead, as shown in FIGS. 6a-d, the price tag pin 50 is anchored to the zipper 22 adjacent to the closed end 32a of the slider 32 when the slider 32 is in the closed position on the zipper 22. Good. The zipper 22 includes shapes 24 and 28 and fins 26 and 30 extending downward from each of the shapes 24 and 28. The price tag pin 50 may extend through either the holes in the shaped portions 24 and 28 (not shown) or the holes in the fins 26 and 30 as shown in FIG. The pin 50 may extend through both the fins and the facing body panel (shown), or may extend only through the fins. Until the pin 50 is removed, the pin 50 prevents the slider 32 from trying to move from its closed position. [0018] In FIGS. 7a-d, the tamper evidence structure is shown in the form of a removable stepped holding member 70 that is removable and adhered to the bag body panel 12 in the closed position of the slider 32, just below the zipper 22. There is. The stepped member 70 is adhered to the bag body panel 12 by a peeling seal or other weak adhesive that allows the stepped member 70 to be peeled off or removed as shown in FIGS. 7b and 7d. The stepped member 70 forms one or more steps 72, each having a slope. The slope of each step 72 is inclined so that the thickness of the step 72 increases as it approaches the end stopper 34. To engage with one of the steps 72, the slider 32 is provided with at least one inwardly extending shoulder 73 contoured to form a protrusion or bump 74. The protrusion 74 may be arranged anywhere along the shoulder portion 73. Further details regarding the contoured shoulder 73 can be found in US Patent Application No. 08 / 938,047, filed April 26, 1997, entitled "High Strength Slider for Recloseable Bags". , The whole is incorporated here as a reference. When the slider 32 is in the closed position, the protrusion 74 of the slider shoulder 73 is engaged with one raised end 76 of the step 72 (FIG. 7a). [0019] In order to create the tamper evidence structure of FIGS. 7a-d, it is desirable to first bond the stepped member 70 to the bag body panel 12. The slider 32 is then engaged with the stepped member 70 using a coupling technique. In one technique, if the slider 32 is of the wing lock type disclosed in US Pat. No. 5,067,208, the slider 32 is mounted on the zipper 22 just above the stepped member 70. The wing lock slider 32 has a pair of hinged wings 78, 79 (not shown) that extend from each other in the open position prior to attaching the slider 32 to the zipper 22. Wings 78 form a shoulder 73 with protrusions 74. The slider 32 is first mounted on the zipper 22 above the stepped member with the wings 78 and 79 open or unfolded, then the wings 78 and 79 are rotated downwards, as shown in FIGS. 7a-d. It is tightened to the closed position. When the wings 78 and 79 are tightened in the closed position, the protrusion 74 engages one end 76 of the step 72. In another technique, the slider 32 is mounted on the zipper 22 at a position away from the stepped member 70. The slider 32 is then moved along the zipper 22 to the closed position. As it approaches the closed position, the slider shoulder 73 is urged to ride over the stepped member 70 until the protrusion 74 engages one end 76 of the step 72. [0020] To remove the stepped member 70 and allow the slider 32 to move from the closed position, the user grabs the tab 71 of the stepped member 70 and places the stepped member 70 on the bag body panel, as shown in FIGS. 7b and 7d. Peel or remove from 12. [0021] [0021] In another embodiment shown in FIG. 7e-h, the stepped member 70'to be separated is integrally molded with the end stopper 34 and along the weak connection region 75 (FIG. 7e) with the end stopper 34. It is detachably connected. To remove the stepped member 70', a force is applied to move the slider 32 away from the closed position, as shown in FIG. 7f, to break the weak connecting region 75. Next, the separated stepped member 70'is removed from under the slider 32. To facilitate the removal of the stepped member 70', a pull tab of the same type as the tab 71 of FIGS. 7a-d may be provided. Instead of separating the stepped member 70'from the end stopper 34 by forcibly moving the slider 32 away from the end stopper 34, the stepped member 70'is provided with a pull tab that the user grabs and pulls. The weak connecting region 75 may be torn and then the detached stepped member 70'removed from under the slider 32. [0022] In FIGS. 8a-d, the tamper evidence structure is shown in the form of a removable plastic shrinkable wrap 80 that wraps the slider 32 when it is in the closed position. The shrinkable wrap 80 is adhered to or heat welded to the bag body panels 12 and 14. The shrinkable wrap 80 may further wrap around the end stopper 34, in which case it does not need to be glued to the body panel to hold the shrinkable wrap 80 in place, but to the end stopper 34. All you have to do is. Alternatively, the shrinkable wrap may be shrink-bonded onto the zipper 22 just in front of the slider 32. In order for the slider 32 to be movable from the closed position, the shrinkable wrap 80 must be torn or pulled from the bag, as shown in FIGS. 8b and 8d. The shrinkable wrap 80 should be notched or perforated for easy removal. Such perforations may be placed on top or side of the shrinkable wrap 80, depending on how you want to break the shrinkable wrap 80. After most of the shrinkable wrap 80 has been torn off, a portion of the shrinkable wrap 80 is glued to the bag body panels 12 and 14 as evidence of tampering, unless the remaining portion interferes with the movement of the slider 32. It may remain as it is. [0023] In FIGS. 9a-d, the tamper evidence structure is shown in the form of a rigid or flexible plastic sleeve 90 that partially covers the slider 32 when it is in the closed position. Alternatively, the sleeve 90 may be lengthened to cover the entire slider 32. The sleeve 90 is either glued to or heat welded to one or both of the bag body panels 12 and 14 as shown in FIGS. 9a and 9c, or is attached to the end stopper 34 (shown). There is. To allow the slider 32 to move away from the closed position, the plastic sleeve 90 must be torn or pulled from the bag as shown in FIGS. 9b and 9d. [0024] In another embodiment of FIGS. 10a-d, the plastic sleeve 100 is mounted across the zipper 22 adjacent to the closed side end 32a of the slider 32 when the slider 32 is in the closed position. The sleeve 100 may be adhered or heat welded to the bag body panels 12 and 14, and / or instead, may be detachably connected to the zipper 22 by friction fitting. Further, the sleeve 100 may extend along only a small portion of the length of the zipper 22 as shown, or along the substantially overall length of the zipper 22 excluding the area of the zipper 22 occupied by the slider 32. It may be stretched. To create a strong frictional fit between the sleeve 100 and the zipper 22, the sleeve 100 is extruded to have an inner profile that matches the outer profile of the zipper 22, as shown in FIG. 10c. Is desirable. When the sleeve 100 is attached to the zipper 22, the sleeve 100 prevents the slider 32 from trying to move from the closed position. To allow the slider 32 to move from the closed position, the sleeve 100 should be pulled upwards across the sleeve 100 to disengage from the zipper 22, or if the sleeve 100 is sufficiently flexible, see FIGS. 10b and 10d. It is removed from the zipper 22 by removing and lifting one side of the sleeve 100 as shown. [0025] In FIGS. 11a-d, the tamper evidence structure is a piece of cardboard, paper, plastic or foil that wraps across the zipper 22 at a position adjacent to the closed end 32a of the slider 32 when the slider 32 is in the closed position. It is shown in the form of 110. The band piece 110 is stapled to the bag body panels 12 and 14. In order for the slider 32 to be movable from the closed position, the stapler must be removed from the strip 110 and then the strip 110 must be removed from the bag. [0026] In FIGS. 12a-d, the tamper evidence structure is shown in the form of a plastic tab 120 that is located adjacent to the closed end 32a of the slider 32 when the slider 32 is in the closed position. The plastic tab 120 is integrally formed with the bag body panels 12 and 14 and includes a pair of tab panels 120a and 120b (FIG. 12c) that are separable along the cut line 122 (FIG. 12a). The cut line may be a perforation, a notch, a thin area, or the like. The tab panels 120a and 120b extend upward and upward on the zipper 22 and are bonded or heat welded to each other above the zipper 22. To allow the slider 32 to move from the closed position, grab the tab panels 120a and 120b and pull them approximately upward along the cut line 122 until they are torn from the bag body panels 12 and 14 as shown in FIGS. 12b and 12d. There must be. [0027] In FIGS. 13a-d, the tamper evidence structure is shown in the form of a latch 130 that extends from the end stopper 34 and is detachably engaged to the slider 32 when the slider 32 is in the closed position. .. The illustrated latch 130 is connected to an end stopper 34 along an instantly breakable hinge that urges the latch 130 toward the position shown in FIG. 13a. The latch 130 may extend along the side surface of the slider 32 as shown, or may extend along the upper wall of the slider 32. As shown in FIG. 13a, the latch 130 is shaped to extend along the outside of the slider 32, forming a distal hook 132 that engages the closed end 32a of the slider 32. Alternatively, the slider 32 may be modified to have a protruding tab so that the latch 130 engages the protruding tab. In order for the slider 32 to be able to move from the closed position, the latch 130 must be rotated outward from the slider 32 until the hook 132 disengages from the slider 32 as shown in FIGS. 13b and 13d. The latch 130 is then detached from the end stopper 34 and removed. [0028] In FIGS. 14a-d, the tamper evidence structure is shown in the form of an arrow-shaped latch 140 that extends from the slider end stopper 34 and engages the slider 32 when the slider 32 is in the closed position. There is. The latch 140 is integrally formed with the end stopper 34, and the slider 32 is originally injection molded to have a long cavity 142 that roughly matches the shape of the latch 140. The lateral dimension of the cavity is slightly larger than the lateral dimension of the latch 140. To "activate" the tampa evidence structure, the latch 140 is inserted into the cavity 142 and the arrowhead jaw-like head 144 of the latch 140 engages the shoulder 146 and snap at a deep position in the cavity 142. As shown, move the slider 32 to the closed position. The latch head 144 is flexible enough that the latch 140 can be inserted into the cavity 142, and the jaw-like shape of the arrowhead substantially prevents the latch 140 from being pulled out of the cavity 142. The inserted latch 140 is shown in Figures 14a and 14c. To allow the slider 32 to move from the closed position, grab the slider 32 and move it away from the closed position with sufficient force to disconnect the latch 140 from the end stopper 34, as shown in FIGS. 14b and 14d. Just need it. The latch 140 remains trapped in the cavity 142 of the slider 32. [0029] As shown in FIGS. 15a-d, the arrow-shaped latch 150 may be extended from the slider 32 and engaged with the end stopper 34. The latch 150 is inserted into the cavity 152 in the end stopper 34 and snaps into the shoulder 154 in the cavity 152. When the slider 32 is pushed out of the closed position, the latch 150 is detached from the slider 32 and remains trapped in the cavity 152, as shown in FIGS. 14b and 14d. [0030] In FIGS. 16a-d, the tampa evidence structure retains a U-shaped rigid or semi-rigid body that extends through slot 162 in the slider 32 and bites into the zipper 22 when the slider 32 is in the closed position. It is shown in the form of member 160 (FIG. 16c). The U-shaped member 160 may be made of metal or plastic. The slider 32 has a cross member 163 and a pair of side walls 164, 165 extending downward from opposite sides of the cross member 163 in the longitudinal direction. The cross member 163 rests on the upper portion of the zipper 22. The side wall 164 has legs 166 and hinged wings 167. After the slider 32 is attached to the zipper 22, the wing 167 surrounds and engages the leg 166. The side wall 165 has legs and hinged wings similar to the legs 166 and wings 167 of the side wall 164. Slot 162 is formed by a small gap separating wing 167 from leg 166. A more detailed description of the structure of the slider 32 can be found in US Patent Application Nos. 08/938, 047, filed April 26, 1997, entitled "High Strength Sliders for Recloseable Bags". The whole is incorporated here as a reference. [0031] The advantage of the tamper evidence structure of FIGS. 16a-d is that the slidable bag with the slider 32 configured as described above is already suitable for accepting the U-shaped member 160. No special features need to be added to the slider 32. Therefore, such a bag with a slider can be refurbished with a U-shaped member 160 to provide the bag with a degree of undue interference. To allow the slider to move from the closed position, the U-shaped member 160 must be removed from the zipper 22 and removed from the slider 32. In order to make the U-shaped member easy to remove, a lever tool such as a screwdriver may be inserted between the slider leg 166 and the U-shaped member 160. In an alternative embodiment, the U-shaped member 160 is replaced with a rigid body member that penetrates through a single slot or hole in the slider 32 to the zipper 22. It is desirable that the rigid body member be provided with some sort of grip that can be manipulated with a hand or tool to make it easier to remove from the slider 32. [0032] In another set of embodiments shown in FIGS. 17a-c to 20a-b, the tampa-evidence structure initially keeps the mouth of the plastic bag folded and then the tampa-evidence structure. The mouth can be widened when the shrimp is removed or broken. This tampa evidence structure can be attached to both a bag with a slider and a bag without a slider. [0033] In FIGS. 17a-c, the tampa evidence created by folding the mouth 170 of the bag and detachably sealing the folded mouth 170 to both sides 16 and 18 of the bag with side spot seals 172 and 174. The structure is shown. As shown in FIGS. 17a and 17b, if the bag is folded, even if the slider 32 is moved from the closed position to the open position, it is difficult to pass through the folded portion 176 after entering the bag. Access to the inside is limited. The folded mouth 170 not only provides evidence of unfair interference, but also especially if seals for fixing the folded mouth 170 are placed along both sides 16 and 18. Provides a convenient grip to hold the bag. In order to access the contents of the bag, the side seals 172 and 174 must be broken so that the mouth 170 can be opened, as shown in FIG. 17c. [0034] As shown in FIGS. 18, 19a-b and 20a-b, the folded mouth portion 170 may be fixed in the folded position by another means. For example, in FIG. 18, the folded mouth 170 is like a spot seal 174 along the side 18 and a price tag pin 180 pointing at the zipper 22 and the unfolded bag near the side 16 adjacent to it. By combining with a flexible member, it is held in a folded state. The price tag pin 180 serves the dual function of keeping the mouth 170 folded and the slider 32 from the closed position until the pin 180 is removed from the bag. In the embodiment of FIG. 18, the spot seal 174 is eliminated and a single price tag pin is provided approximately in the middle of the sides 16 and 18, or a pair of price tag pins are provided near the sides 16 and 18 respectively. You may. All price tag pins near the side 16 are placed adjacent to or through the slider 32 along the zipper 22 to prevent the slider 32 from moving from the closed position until the pins are removed from the bag. It is desirable to have. [0035] In FIGS. 19a-b, the folded mouth 170 is secured in a folded state by one or more spot seals 190 and 192 that detachably seal the bag panel 12 to the bag panel itself. .. For example, the spot seal may be a strippable seal or a "dirty" seal. The portion of the bag panel 12 of the mouth 170 is adhered to the unfolded portion of the adjacent bag panel 12. If desired, the placement of the spot seals 190 and 19 can be devised to create a grip to hold the bag. [0036] In FIGS. 20a-b, the folded mouth 170 is one or more partially removable stickers (adhesive strips) that attach the mouth 170 to the unfolded portion of the adjacent bag panel 12. It is fixed in a folded state by a piece) or a pressure-sensitive label 200. One of the stickers 200 is placed adjacent to or on the slider 32 along the zipper 22 to prevent the slider 32 from moving from the closed position until the sticker is removed from the bag. Breaking the middle part of each sticker 200 can unfold the mouth 170, but the end part of each sticker 200 remains glued to the bag, providing evidence of unfair interference. [0037] Each tampa evidence structure described above makes it difficult to access the inside of the bag before removing or breaking the tampa evidence structure. Without an upper flange that can be grabbed, it is difficult to grab and open the zipper 22 by hand without using the slider 32. Therefore, when it comes to these tamper-evidence structures that prevent the slider 32 from moving from the closed position, such tamper-evidence structures need not be tamper-proof packaging, but they should be tamper-resistant packaging. It effectively prevents the contents of the bag from being tampered with, to the extent that it is particularly useful for non-food items and certain food items that should be kept. For example, the tamper evidence structures in FIGS. 4a-d, 8a-d, 9a-d, 10a-d, 11a-d, 12a-d cover or adjoin a slider in closed position. Using removable cardboard, paper, plastic, or foil material that is glued, affixed, friction-fitted, or something to the bag to hold the material in place. It is advantageous in that resistance to unjustified interference is realized by being connected to the bag by another method. When the member is composed of plastic, the plastic is a polyethylene-based polymer, polystyrene, nylon, polycarbonate or a polymer or copolymer made of another material of the same kind. Polyethylene-based polymers include low density polyethylene, linear low density polyethylene, metallocene, ethylene vinyl acetate or other materials of the same type. The shrinkable wrap 80 in Figures 8a-d is preferably made of ordinary low density polyethylene. The plastic tab 120 of FIGS. 12a-d is made of the same material as the bag body panels 12 and 14 because the removable tab panels 120a and 120b are formed integrally with the bag body panels 12 and 14. [0038] In addition, in the tamper evidence structures of FIGS. 5a-d, 6a-d, resistance to undue interference is at least on the zipper 22 to prevent the slider 32 from moving from the closed position (FIGS. 5a-d, 6a-d). And it is useful in that it is realized by using a normal price tag pin which is optionally attached to the slider 32 (Fig. 5a-d) as well. The tamper evidence structure of FIGS. 13a-d, 14a-d, 15a-d is removable (FIG. 13a-d) or has resistance to undue interference that detachably connects the slider 32 to the end stopper 34. It is useful in that it is realized using a fractureable latch (Figs. 14a-d, 15a-d). The stepped members of FIGS. 7a-h are equally effective in providing resistance to undue interference with the contents of the slider bag. [0039] Unlike the tamper-evidence structures of FIGS. 4a-d to 16a-d, the tamper-evidence structures of FIGS. 17a-c, 18, 19a-b and 20a-b prevent the slider 32 from moving from the closed position. Not dependent. Rather, the tampa evidence structure in Figures 17a-c, 18, 19a-b, 20a-b relies on keeping the bag mouth folded, even without the slider 32 and zipper 22. It is valid. Therefore, unlike other tampa-evidence structures, the tampa-evidence structures in Figures 17a-c, 18, 19a-b, 20a-b can be applied to virtually any type of bag. However, if a bag with a slider is adopted, the mouth of the bag will be held in a folded state until the appropriate tamper evidence structure is broken or removed, and the movement of the slider from the closed position will be hindered. It is also conceivable to use the tampa evidence structure from 16a-d in combination with the tampa evidence structure shown in FIGS. 17a-c, 18, 19a-b and 20a-b. Examples of bags combining multiple tampa evidence structures are shown in Figures 18 and 20a-b.
