Sheet packaging

Abstract

A sheet packaging material has a corrugated sheet layer bonded to a backing sheet layer. The corrugated sheet layer forms parallel grooves. The packaging includes gaps that pass through the corrugated sheet layer and the backing sheet layer at intervals along the grooves, thereby forming a plurality of island-like portions interconnected by bending. Each island-like portion has a grooved portion and a backing portion between adjacent gaps and is bonded together at their respective edges, and each bend includes the portion of the corrugated sheet layer and the backing sheet layer bonded together. The bending gives the packaging ultra-flexibility, wherein each bend has an independent bending axis, and the bend can twist and bend along the bending axis.

Description

Technical Field

[0001] This invention generally relates to sheet packaging, and more specifically, to an ultra-flexible configuration of sheet packaging. Background Technology

[0002] Cushioning sheets are used for packaging, including various configurations, and feature plastic bubble wrap.

[0003] However, packaging based on recyclable cardboard is preferable as an alternative to plastic bubble wrap, and in this regard, US 2503874A (Ives), dated April 11, 1950, proposed a planar reinforcing layer bonded to corrugated board layers. Professor Ives cut rows of straight slits in the cardboard layer, imparting flexibility to the grooves in the cardboard layer.

[0004] The present invention seeks to provide sheet packaging that will overcome or substantially improve at least some of the deficiencies of the prior art, or at least provide an alternative.

[0005] It should be understood that if this invention references any prior art information, such reference does not imply that the information constitutes part of general knowledge in the field of Australia or any other country. Summary of the Invention

[0006] This invention provides a sheet packaging in which a corrugated board layer is bonded to a backing board layer. The corrugated board layer forms parallel grooves.

[0007] The packaging includes gaps that pass through the corrugated board layer and the backing board layer at intervals along the grooves.

[0008] The gaps formed by the present invention, which pass through the corrugated sheet layer and the backing sheet layer at certain intervals along the grooves, form a plurality of island-shaped portions interconnected by bending. Each island-shaped portion includes a groove portion and a backing portion between adjacent gaps, and are bonded together at their respective edges, and each bend includes a portion of the corrugated sheet layer and the backing sheet layer bonded together.

[0009] These bends give the packaging ultra-flexibility, with each bend having an independent bending axis along which the bend can twist and flex. Furthermore, the bends allow the packaging to deform without compromising the cushioning structural integrity of the island sections.

[0010] For example, unlike the arrangement of Ives, which can only bend along grooves, through rows of slots, or diagonally through diagonal slots, this package can be twisted and bent into any shape and form, including through non-orthogonal and non-diagonal axes, such as... Figure 7 and Figure 8 as well as Figure 9 and Figure 10 As shown.

[0011] The rigidity and flexibility of the packaging of this invention can be controlled by the degree of edge overlap of the island-shaped portions of adjacent grooves.

[0012] The present invention also provides embodiments in which the size and positioning of the gaps and island portions can be adjusted to control the rigidity and other performance characteristics of the packaging.

[0013] The corrugated board layer and the backing board layer preferably comprise cardboard and can be manufactured during the manufacturing process, wherein the corrugated board layer is bonded to the backing board layer and then simultaneously punched, cut or formed with gaps between the two.

[0014] Other aspects are also disclosed in this invention. Attached Figure Description

[0040] Figure 1 and Figure 2 The image shows a package 100, with a corrugated board layer 101 adhered to a backing board layer 102. Both the corrugated board layer 101 and the backing board layer 102 are preferably cardboard. Furthermore, the package 100 preferably comprises biodegradable and / or degradable materials.

[0041] The corrugated sheet layer 101 forms parallel grooves 103. The corrugated sheet layer 101 forms a generally wavy pattern, and may be generally sinusoidal, and is bonded to the backing sheet layer 102 along the apex of the lower surface of the corrugated sheet layer using an adhesive or the like. Other shapes of the corrugated sheet layer 101 are conceivable, including corrugated sheet layer 101 with a flat-topped trapezoidal cross-sectional shape.

[0042] Packaging 100 includes gaps 104 at intervals along grooves 103 passing through corrugated board layers 101 and backing board layers 102, thereby forming a plurality of island-like portions 105 interconnected by bends 106, such as Figure 1 As shown.

[0043] refer to Figure 2 Each island-shaped portion 105 includes a recessed portion 107 and a backing portion 108, which are bonded along the respective edge of the corresponding recess 103.

[0044] In addition, each bend 106 includes a portion where a corrugated board layer 101 and a backing board layer 102 are bonded together.

[0045] Figure 3 The curve 106, which bends between adjacent island-shaped portions 105, is shown. Figure 4 The bend 106, which twists between the island-shaped portions 105, is shown. Figure 5 The bend 106 is shown to bend and twist between the island-shaped portions 105.

[0046] Figure 6 This shows the four-part structure of island-shaped portions 105 interconnected by corresponding bends 106 around the gaps 104 when the package 100 is laid flat. Figure 7 Showing Figure 6 The packaging was twisted and bent, demonstrating the super flexibility imparted by each of the 106 bends with an independent bending axis.

[0047] Figure 8 The diagram further illustrates how the elongated bend 106A bends itself under compression, while the relative bend 106B bends under tension, thereby causing the package 100 to twist and bend.

[0048] Figure 9 The illustration shows a package 100 folded ultra-flexibly onto a corrugated sheet layer 101 according to one embodiment, while Figure 10 Another embodiment of the packaging 100 is shown, which is ultra-flexibly bent on the backing plate layer 102.

[0049] according to Figure 1 In some embodiments, the gaps 104 may typically be rectangular, wherein each gap 104 includes a straight edge 109 aligned along the groove axis 110 and a straight edge 111 orthogonal to the groove axis 110.

[0050] Figure 21 and Figure 22 The voids 104 are shown to be non-rectangular. According to the illustrated embodiment, each void 104 may also include a straight edge 109 along the groove axis 110, but wherein the voids 104 widen along the groove axis 110 at their opposite edges to increase the effective central cushioning width of the island portions 105 along the groove axis, while reducing the width of the bends 106 along the groove axis to increase flexibility. In this way, the horizontal cross-section of the shape of the voids 104 and / or the island portions 105 can be adjusted to control the flexibility and / or cushioning of the package 100.

[0051] according to Figure 1 In the embodiment shown, the gaps 104 of adjacent grooves 103 are alternately arranged along the groove axis 110, such that each island portion 105 is diagonally interconnected to the quarters 105 of the adjacent island portion.

[0052] according to Figure 1 In one embodiment, the island-shaped portions 105 of adjacent grooves 103 overlap along the groove axis 110, thereby increasing the stiffness along the groove axis. Furthermore, according to... Figure 1 In one embodiment, the gaps 104 between adjacent grooves 103 do not overlap on the groove axis 110, thereby reducing the stiffness of the groove axis 110.

[0053] according to Figure 11 and Figure 12 The embodiments, and Figure 1 and Figure 2 Compared to the previous embodiment, the edges of the island portions 105 of adjacent grooves 103 are aligned along the groove axis 110, thereby reducing the stiffness along the groove axis and forming discrete broken lines on the groove axis 110.

[0054] according to Figure 13 In one embodiment, the gap 104 is wider than the island portion 105 along the groove axis, thereby increasing flexibility.

[0055] Furthermore, the gaps 104 of adjacent grooves 103 overlap along the groove axis 110, thereby forming a bend 106 with a longitude along the groove axis 110, thus increasing its flexibility.

[0056] Figure 15 One embodiment is shown in which the gap 104 is narrower along the groove axis 110 than the island portion 105, thereby increasing stiffness along the groove axis. This is consistent with... Figure 13 The embodiments were compared, Figure 13 It is shown that the gap 104 along the groove axis 110 is wider than the island portion 105, thereby reducing the stiffness along the groove axis 110.

[0057] also, Figure 15 The edges of the gaps 104 along the groove axis 110 of the adjacent grooves 104 overlap, thereby increasing the flexibility of the longitude of the bend 106 on the groove axis 110.

[0058] Figure 17 One embodiment is shown in which the gaps 104 of the parallel grooves 103 are arranged to overlap and not overlap alternately along the groove axis 110, thereby forming a pattern of shorter bends 106C and longer bends 106D along the groove axis, thereby giving the package 100 a non-uniform bending characteristic along the groove axis 110.

[0059] according to Figure 19 In one embodiment, the gaps 104 are aligned on the groove axis 110, thereby forming a bend 106E between adjacent island portions 105 and a bend 106F between adjacent gaps 104.

[0060] Figure 23 and 24 A similar embodiment is shown, but the gap 104 therein is much narrower.

[0061] The manufacture of packaging 100 may include adhering corrugated board layer 101 to backing board layer 102, and subsequently stamping, forming or cutting gaps 104 in two layers.
