Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging structure technology, and in particular to a multi-layer composite pearl cotton shockproof packaging structure. Background Technology
[0002] Pearl cotton (also known as polyethylene foam or EPE) is a lightweight, soft packaging material with excellent cushioning properties. It is made from polyethylene resin through a foaming process, resulting in numerous small air bubbles that form a pearl-like structure. This provides excellent shock and pressure resistance, effectively protecting fragile items such as electronic products and glassware.
[0003] Existing EPE foam packaging structures come in various forms, with mold-type packaging structures being the most widely used. These structures primarily involve creating a mold cavity similar to the product on a sheet of EPE foam, allowing the product to be embedded within the cavity for packaging and protection. However, current mold-type EPE foam packaging structures cannot be sealed, and the EPE foam cover plate at the mold end needs to be secured with tape or string, affecting ease of use. Therefore, a multi-layer composite EPE foam shockproof packaging structure is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figure 1-4 The diagram shows a multi-layer composite pearl cotton shockproof packaging structure.
[0027] Example 1 includes a packaging board 100, which is provided with storage cavities 105 for product storage. When packaging oval or round fragile items such as eggs, the storage cavities 105 are square or round. The fragile items are stored by pressing them into the storage cavities 105. A top cover 102 is attached to the end face of the packaging board 100 to seal the end face of the packaging board 100. Adhesive members are provided on the opposite side of the packaging board 100 and the top cover 102, and the top cover 102 is attached to the packaging board 100 by the adhesive members. The top cover 102 is detachable and is attached to the end face of the packaging plate 100 by adhesive. The top cover 102 is fixedly attached to the end face of the packaging plate 100, covering the port of the storage cavity 105, which can achieve the function of blocking and protection, and enhance the protection of fragile items. At the same time, the adhesive allows the top cover 102 to be easily installed and removed from the end face of the packaging plate 100 without the need to use additional tape to bind and fix it, thereby improving the convenience of using the top cover 102 on the end face of the packaging plate 100.
[0028] The adhesive components include two hook-and-loop fasteners 104 and two hook-and-loop fasteners 103. Two hook-and-loop fasteners 104 are symmetrically fixed on both sides of the packaging board 100 facing the top cover 102. Two hook-and-loop fasteners 103 are symmetrically fixed on both sides of the top cover 102 facing the packaging board 100. The hook-and-loop fasteners 103 and the hook-and-loop fasteners 104 are bonded to each other on opposite sides. The detachable bond between the hook-and-loop fasteners 103 and the hook-and-loop fasteners 104 allows the top cover 102 to be fixed to the packaging board 100 by simply bonding the hook-and-loop fasteners 103 and the hook-and-loop fasteners 104 on their opposite sidewalls when it is installed on the end face of the packaging board 100. At the same time, disassembly can be achieved by simply tearing the hook-and-loop fasteners 103 and the hook-and-loop fasteners 104 apart manually. The operation is simple and convenient, and the product is easy to use.
[0029] It should be noted that a positioning protrusion 106 is fixedly connected to the inner wall of the storage cavity 105. There are three positioning protrusions 106 arranged in a ring-shaped array. The thickness of the positioning protrusions 106 gradually decreases from the center to both sides. Both the positioning protrusions 106 and the packaging plate 100 are made of pearl cotton, which has good flexibility. This allows fragile items to be pressed into the storage cavity 105, and the pressure exerted on the sidewalls of the positioning protrusions 106 provides a reverse compressive force to the fragile items, making the storage of fragile items in the storage cavity 105 more stable. A bottom plate 101 is integrally formed on the side of the packaging plate 100 opposite to the top cover 102. The bottom plate 101 can seal the other end of the packaging plate 100. In other embodiments, the bottom plate 101 can also be attached to the packaging plate 100 using adhesive. The end faces are detachably connected. The packaging plate 100 has a double-layer stacked structure. The double-layer structure of the packaging plate 100 allows for a higher height of the storage cavity 105, thus accommodating the placement of larger fragile items. Both the bottom plate 101 and the top cover 102 have protrusions distributed on the side facing the packaging plate 100. The protrusions extend to the inner end of the storage cavity 105. The end faces of the bottom plate 101 and the top cover 102 are provided with integrally formed protrusions. When the bottom plate 101 and the top cover 102 are connected to the end face of the packaging plate 100, the end of the protrusion can be inserted into the inner end of the storage cavity 105 to provide auxiliary support for the fragile items located in the storage cavity 105. This further ensures the stability of the fragile items placed in the storage cavity 105 and further improves the protective properties of the fragile item packaging.
[0030] Example 2, based on Example 1, further illustrates that the packaging board 100, bottom board 101, and top cover 102 all include a low-density layer 107 and a high-density layer 108. The low-density layer 107 has a double-layer structure, with the two low-density layers 107 stacked vertically. The high-density layer 108 is positioned between the two low-density layers 107. The packaging board 100, bottom board 101, and top cover 102 use the double low-density layer 107 to wrap the high-density layer 108. The low-density layer 107 is low-density pearl cotton, and the high-density layer 108 is high-density pearl cotton. Through the difference in density between the two, the packaging board 100, bottom board 101, and top cover 102 have both softness and high compressive strength, thereby providing good shock absorption and cushioning protection for fragile items and improving the protection of fragile item packaging.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
