The main body can made of a low-density foam material having a density lower than 30 kg/m3. The reinforcement structure can be made of a paper material, a plastic material, a softwood material, etc., and can be placed in the main body, so that the structural strength of the low-density foam material is enhanced to allow a higher vertical compressive strength for the elastic composite structure and to provide better cushioning effects and supporting strength.

This non-provisional application claims priority to and the benefit of, under 35 U.S.C. § 119(a), Taiwan Patent Application No. 110107575, filed in Taiwan on Mar. 3, 2021. The entire content of the above identified application is incorporated herein by reference.
FIELDThe present disclosure relates to an elastic composite structure, and more particularly to an elastic composite structure that is collectively formed by arranging reinforcement structures in a low-density foam material, and can be a component of an anti-collision packing object.
BACKGROUNDGenerally, products are properly packed for transport or sale. A relatively sophisticated product (e.g., an electronic device such as a smartphone, tablet computer, or router) requires a relatively large amount of packing material in order to be protected to a relatively high level, wherein the packing material typically includes anti-collision packing objects for example. These anti-collision packing objects have an elastic structure so that when the box in which the product is packed is hit, shaken, compressed (e.g., by the weight of another boxed product stacked on the box), or subjected to a change in pressure (e.g., a variation in the atmospheric pressure when the product is shipped by air), the anti-collision packing objects can provide proper cushioning and protection to reduce the chance of product damage, thereby allowing the product to reach its buyer while staying intact.
An existing anti-collision packing object may include a foam material and a paper material and is usually made by coating the surface of the former with the latter. Or, a paper-lined partition or a paper-made accessory box can be used as a cushioning structure. The aforesaid structures are typically used in packing boxes (or cases) where there is no limitation on the cushioning space, i.e., where a relatively large cushioning space can be planned to accommodate a considerable amount of foam material for providing effective protection for the integrity of the packed product. The aforesaid packing arrangements, however, tend to result in huge packing boxes, which may in turn take up excessive storage space, transportation space, or shelf space. The enormous amount of foam material used in such packing boxes also constitutes a wasteful use of resources and causes an increase in packing cost. If fixed-size packing boxes (or cases) must be used to comply with the volume standards of transported goods, there will be limitation on the cushioning space in such a box, and if a low-density foam material (i.e., a foam material with a density lower than 30 kg/m3) is used to form the cushioning foam walls, the walls will be too soft (i.e., have too low supporting strength) to provide effective protection, thus increasing the chance of product damage. In light of this, and in order to provide better cushioning and protection, it is generally desired to use foam material of a higher density, typically higher than 30 kg/m3 and hence the name high-density foam material.
However, high-density foam material is more costly, and also more difficult to obtain, than its low-density counterpart. In Taiwan for example, high-density foam materials are mostly imported, which explains why product packing cost in Taiwan has stayed high and has undoubtedly raised the expenditures of businesses or consumers. One major niche point provided by the present disclosure lies in the provision of an effective solution to the foregoing issues so that packing cost and the volumes of packed products can be reduced while product protection is enhanced.
SUMMARYIn view of the fact that there is still room for improvement for the conventional anti-collision packing objects, as a result of repeated research and tests, the present disclosure provides an elastic composite structure having a low-density foam material and at least one reinforcement structure and an anti-collision packing object including the same, which contribute to a package structure design whose packing cost and volume are reduced while providing sufficient protection.
One aspect of the present disclosure is directed to an elastic composite structure including at least one main body and at least one reinforcement structure. The at least one main body is formed with at least one opening, and made of a low-density foam material having a density lower than 30 kg/m3. The at least one reinforcement structure is made of a material including at least one of a paper material, a plastic material, and a softwood material, can be in a columnar shape or formed as a plate, and can be inserted into the opening to be placed in the main body. Therefore, by the design of the reinforcement structure, the structure of the low-density foam material is reinforced to allow a higher vertical compressive strength for the elastic composite structure and to provide better cushioning effects and supporting strength.
In certain embodiments, the opening is adjacent to a corner of the main body. In certain embodiments, the reinforcement structure is made of corrugated paperboard.
In certain embodiments, the bursting strength of the corrugated paperboard is 4-12 kgf/cm2.
In certain embodiments, the thickness of the reinforcement structure is 2-4 mm.
In certain embodiments, the reinforcement structure is shaped as a triangular column.
Another aspect of the present disclosure is directed to an anti-collision packing object that can be placed in a case, and includes at least one base portion and at least one elastic composite structure including at least one main body and at least one reinforcement structure. The at least one main body is made of a low-density foam material having a density lower than 30 kg/m3 and arranged therein with the at least one reinforcement structure that is made of a paper material, a plastic material, and a softwood material, etc., so that the anti-collision packing object can provide proper protection to a product without needing excessive cushioning space.
In certain embodiments, the base portion is made of a paper material.
In certain embodiments, the base portion is made of a foam material.
In certain embodiments, the elastic composite structure can be placed between the case and the base portion.
These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

It can be known from the foregoing test results that the elastic composite structure 1 according to the present disclosure has evidently higher vertical compressive strength than the low-density foam materials used without the reinforcement structures 12 and does not require a large cushioning space. Therefore, when the packing box to be used is required to comply with the volume standards of transported goods, the elastic composite structure 1 can provide adequate protection in a limited space. The elastic composite structure 1 also allows the overall packing cost to be much lower than that when only a high-density foam material is used. It is expected that the elastic composite structure 1 will be favored by businesses and general consumers alike.
