PACKING SET

The subject matter currently described relates to a packaging assembly, for example a packaging assembly for containing a packaged object during shipment

Background of the Invention

Protective packaging structures can be used to help protect a product during transport, for example, against physical impact, dust and other contaminants. For example, a product may be enclosed in a box with additional packaging materials (eg, crumpled paper, plastic cushions filled with air, molded foam) to retain movement of the product within the box and cushion the product.

One type of packaging structure is known as retention packaging. In typical retention packaging, a product is retained between a film and a rigid backing frame to which the film is attached. Examples of retention packages are described in more detail in US Patents 5,678,695; 5,893,462; 6,010,006; 6,148,590; 6,148,591; 6,289,655; and 6,311,844, each of which is incorporated herein by reference in its entirety.

Although these retention structures provide a level of protection for the packed object, there is room for improvement, for example, by increasing the system's ability to receive impacts such as falls, while minimizing the increased use of materials to provide the improvement. .

Summary of the invention

One or more modalities of the subject matter currently described may face one or more of the aforementioned problems.

A packaging structure for containing an object comprises a panel and a film. The panel comprises a platform portion, an end flap portion, and a hinge portion. The platform portion has a support surface to support the object. The end flap portion is foldably connected to the platform portion along the fold line of the end flap. The hinge portion comprises upper and lower hinge sections foldably connected to each other along a first hinge fold line between the upper and lower hinge sections. The hinge portion is delimited by (i) a second hinge fold line between the platform portion and the upper hinge section, (ii) at least one upper hinge cut line between the platform portion and the section top hinge and extending from the extreme flap fold line to the second hinge fold line, (iii) a third hinge fold line between the end flap portion and the bottom hinge section and (iv) at least one bottom hinge cut line between the end flap portion and the bottom hinge section and that It extends from the extreme flap fold line to the third hinge fold line.

The film extends through the end flap fold line and is attached to the end flap portion and is attached to the outside of the panel of the end flap portion. The packaging structure is foldable to a mated position having (a) the end flap portion bent along the end flap fold line away from the bearing surface of the platform portion to define an acute angle between the platform portion and the end flap portion and (b) the hinge portion folded along the first, second and third hinge fold line to separate the top hinge section and platform portion along at least one top hinge cut line, separate bottom hinge section and end flap portion along of at least one lower hinge cut line, and extending the upper and lower hinge sections within the acute angle between the platform portion and the end flap portion.

In the engaged position, the hinge is believed to function as a spring to provide increased resistance to, and / or damping from, compression or drop forces generated on the packaging assembly incorporating the packaging structure. In some embodiments, this attribute can be provided to the packaging structure without using additional materials beyond those normally provided for the retention structure.

These and other objects, advantages, and features of the various embodiments of the subject matter currently described will be more easily understood and appreciated by reference to the detailed description and drawings.

Detailed description of the invention

The subject matter currently described teaches various modalities of a packaging structure for containing an object, as well as a packaging assembly for containing the packaging structure within a box. The packaging structure comprises a panel and a film attached to the panel. The panel comprises at least one end flap and at least one hinge portion, as described in more detail below.

Packing structure

In one embodiment of the disclosed material, panel 14 comprises a platform portion 18 having a support surface 20 for supporting object 12 contained by the packaging structure (see, e.g., Figure 5). The panel comprises a lightweight, substantially rigid, collapsible material, for example, one or more of any of the following materials: cellulosic based materials (e.g., cardboard, corrugated cardboard, cardstock), plastic, and compressed foam . For example, panel 14 may comprise corrugated cardboard, for example, any of B-channel, C-channel and / or E-channel single-wall corrugated cardboard, B / C double-wall corrugated cardboard and / or corrugated cardboard double wall E / B. the panel, and any of the tray panels and racks of the various modalities described herein, may have an average thickness of, for example, at most and / or at least any of the following thicknesses: 0.076, 0.152, 0.304, 0.635, 0.762, 1.016 and 1.27 cm.

The bearing surface 20 of the platform portion 18 can be provided by a substantially continuous platform portion, as illustrated in the accompanying drawings. Alternatively, the supporting surface of the platform portion may be discontinuous, for example where the platform portion comprises a material of

USA 7,086,534 (eg, Figure 2); 6,302,274 (eg, Figure 1); and 5,388,701 (eg, Figure 1), and US Patent Application Publication No. 2011/0240515 Al, the disclosures of which are incorporated herein by reference in their entirety.

Panel 14 comprises an end flap portion 22 foldably connected to platform portion 18 along an end flap fold line 24. End flap fold line 24 is separated from, and may be parallel to, , an outer edge of panel 14. A fold line, as used here (and as illustrated in the drawings of the unfolded positions, laid flat as a broken line) represents a line along which the panel can be folded, curled, embossed, drilled , marked or with another line of weakness to increase the bending capacity of the panel, frame or other material along the line of bending. For example, the end flap bending line 24 may include one or more through grooves extending parallel along its length leaving a sufficient portion of the end flap bending line intact to securely bond the flap portion end 22 to platform portion 18 of panel 14 so that end flap portion 22 is foldably connected to platform portion 18. The grooves through the fold line can facilitate bending at the first flap along the end flap fold line 24 by reducing the amount of panel material that has to be bent. As used herein, terms such as parallel or perpendicular are not intended to indicate that parallel or perpendicular orientation requires mathematical precision, but rather indicates general orientation that accepts moderate ranges of absolute parallel or perpendicular deviation that are commonly acceptable within the meaning of these terms within the container fold field.

Referring, for example, to Figure 2, panel 14 comprises a hinge portion 26 comprising an upper hinge section 28 and a lower hinge section 30 which are foldably connected to each other along the first line of hinge bend 32 between the upper and lower hinge sections. The hinge portion 26 is delimited by: (i) a second fold line 34 between platform portion 18 and top hinge section 28, (ii) at least one top hinge cut line between platform portion 18 and top hinge section 28 that it extends from the end flap fold line 24 to the second hinge fold line 34, for example the first upper hinge cut line 36 and second upper hinge cut line 38 (FIG. 2), (iii) third hinge fold line 40 between the end flap portion 22 and the bottom hinge section 30 and (iv) at least one bottom hinge cut line between the end flap portion 22 and the hinge section Bottom 30 extending from end flap fold line 24 to third hinge fold line 40, eg, first bottom hinge cut line 42 and second bottom hinge cut line 44 (FIG. 2). The second hinge bend line 34 can be oriented parallel to the first hinge bend line 32. The third hinge bend line 40 can be oriented parallel to the first hinge bend line 32.

A cut line as used here (and as illustrated in the drawings from the unfolded, flat lay position, as a solid line within the panel) represents a line along which the panel is either cut, or it is otherwise punctured, marked, or weakened to such an extent that the panel is adapted to be easily detached (ie, by hand) along the line of cut. A cut line can be curved or straight.

Panel 14 may further comprise a complementary end flap portion 46 foldably connected to platform portion 18 along complementary end flap fold line 48. Complementary end flap fold line 48 is oriented on a end of platform portion 18 that is opposite end flap fold line 24, and is separated from, and may be parallel to, an outer edge of panel 14.

The panel 14 may further comprise a complementary hinge portion 50 comprising a complementary top hinge section 52 and complementary bottom hinge section 54 that are foldably connected to each other along the first complementary hinge fold line 56 between the complementary top and complementary bottom hinge sections. The complementary hinge portion 50 is delimited by: (i) the second complementary hinge fold line 58 between the platform portion 18 and the complementary top hinge section 52 (ii) at least one complementary top hinge cut line between the platform portion 18 and the complementary top hinge 52 extending from the complementary end flap fold line 48 to the second complementary hinge fold line 58, for example, the first complementary top hinge cut line 60 and second complementary top hinge cut line 62 (Figure 2), (iii) third complementary hinge fold line 64 between complementary end flap portion 46 and complementary bottom hinge section 54 and (iv) at least one complementary bottom hinge cut line between complementary end flap portion 46 and the complementary bottom hinge section 54 extending from the complementary end flap fold line 48 to the third complementary hinge fold line 64, for example, first complementary lower hinge cut line 66 and second complementary lower hinge cut line 68 (figure 2).

The second complementary hinge bending line 58 may be oriented parallel to the first complementary hinge bending line 56. The third complementary hinge bending line 64 may be oriented parallel to the first complementary hinge bending line 56.

Panel 14 may further comprise a side flap portion 74 and / or a complementary side flap portion 78. Side flap portion 74 is foldably connected to platform portion 18 by a side flap fold line 76. The side flap fold line 76 is separated from, and can be parallel to, an outer edge of the panel 14. In addition, the flap fold line 76 can be oriented transverse to the end flap fold line 24. Side flap portion 74 is foldably connected to platform portion 18 by side flap fold line 76. Complementary side flap fold line 80 is separated from, and may be parallel to, an outer edge of the panel 14. Furthermore, the complementary side flap fold line 80 can be oriented on one side of the platform portion 18 which is opposite to the side flap fold line 76, can be separated from, and parallel to, an outer edge of the panel 14, and can be oriented transverse to the end flap fold line 24.
