Description

Combined cushioning packaging material

The present invention relates to a combined cushioning packaging material; in particular, the present invention relates to a combined cushioning packaging material for packaging sheet-like articles.

The packaging of fragile items has always been an important issue in the delivery of products. When the packaging is not properly prepared, it often causes damage to the articles during transportation, thereby increasing production costs. In particular, fragile articles having a special size and shape, such as liquid crystal glass or display panels, are liable to cause stress concentration due to their special size and shape, and increase the possibility of damage.

Taking the transportation of the display panel as an example, when transporting the display panel, it is usually necessary to add a cushioning material such as a styrofoam to the transported cardboard box to reduce the direct impact of the external force on the display panel. However, in the current packaging structure, considering the manufacturing cost of the buffer material, and considering that the buffer material of too large a block is difficult to manufacture and store, a plurality of scattered small buffer materials are usually placed in the carton, and are placed on the display panel. Corner or middle position. However, in this design mode, since the buffer materials are independent of each other, when the assembly tolerance between the cushioning material and the outer carton is too large, the cushioning material is easily displaced or detached from the display panel, and the protective effect is lost.

It is an object of the present invention to provide a combined cushioning packaging material that enhances the protective effect on a protected product.

Another object of the present invention is to provide a combined cushioning packaging material that can increase the coverage of a protected product.

The combined cushioning packaging material comprises a first body and a second body. The first body and the second system are fitted to each other to provide cushioning protection for the packaged article. The first body includes a first side having a first side and a first guiding portion; wherein the first side is facing a side of the second body. The first guiding portion is disposed on the first side and has a first guiding surface. The first guiding surface is inclined toward the first side and is sandwiched into the first wedge-shaped space between the first side. The second body includes a second side having a second side and a second guiding portion; wherein the second side is facing the one side of the first body. The second guiding portion is disposed on the second side and has a second guiding surface. The second guiding surface is inclined toward the second side surface and sandwiched into the second wedge-shaped space between the second side surface.

At the beginning of the combination, the leading edges of the first guiding surface and the second guiding surface overlap each other, and the first side and the second side sandwich a gap. When the first body is pressed downward, the first guiding surface and the second guiding surface slide relative to the direction of increasing the contact area, so that the first guiding portion extends into the second wedge-shaped space, and the second guiding portion Extend into the first wedge space. By the relative contact and sliding of the first guiding surface and the second guiding surface, when the original first body approaches the second body in the vertical direction, horizontal movement is simultaneously generated, and the two are brought closer to each other. Produce a concentrated effect.
