Description

Buffer material for packaging {CUSHIONING MATERIAL FOR PACKAGING}

The present invention relates to a cushioning material for packaging, and more particularly, is disposed at the edge of the packaged object, spaced and fixed to the packaged object by a predetermined distance from the box wall, to prevent shaking of the packaged object in the box, and absorbs external shocks The present invention relates to a cushioning material for packaging to protect a packaged product.

When packing boxed products such as televisions, washing machines, refrigerators, sound playback players, video players, and DVD players in boxes, packaging cushioning materials are used to space the product away from the box and absorb external shocks. Commonly used. Packaging cushions are partly placed on the outside of the product to prevent direct contact between the box and the product, placed between the box and the product to obstruct, absorb and dissipate direct impact transmission from the outside, and form a support frame on the outside of the product. To distribute the load concentrated on the product.

In consideration of the functions of the packaging cushioning material, the packaging cushioning material may be applied in various forms and structures according to the characteristics of the packaged package's fragility, the shape of the packaged package, the weight of the packaged package, the product's loading method and the transportation method.

Conventionally, polystyrene foam (also referred to as "styrofoam") is generally used as a material for packaging cushioning, and mainly includes a structure accommodating each vertex portion of the product, a structure accommodating each corner of the product, and one side of the product. It is used as a receiving structure.

Expandable polystyrene is widely used as a packaging cushion because of its light weight and easy molding. However, the packaging cushioning material made of expandable polystyrene is not easily stored after opening the product, so it is mostly thrown away as garbage. It causes serious environmental pollution.

In order to overcome this problem, there is disclosed a packaging cushioning material using paper such as cardboard, which is an environmentally friendly material. Korean Unexamined Patent Application Publication No. 2001-0109035 discloses a "method for manufacturing a packaging buffer material", and Korean Unexamined Patent Publication No. 1996-0010232 discloses a "method for manufacturing a product packaging buffer material". The packaging buffer disclosed in the above two publications is characterized by forming a cushioning material for packaging by folding a sheet of cardboard, such as cardboard.

The two packaging buffers have the advantage of being recyclable, easy to dispose of, and no concern for environmental pollution since paper is used. However, since paper is formed by folding layers, it is heavy for packaging, and in the case where a large volume of cushioning material is required, the paper consumption is remarkably increased and the cost is excessively increased.

Accordingly, an object of the present invention is to provide a cushioning material for packaging that is lightweight, has sufficient durability, and is easy to assemble and disassemble the cushioning material by using a sheet material that can be folded, such as paper.

Form the jaw. The first and second fixing jaws 462 and 464 are restrained and fixed by the support pieces 420 that are bent like the fixing pieces 422a and 426b.

The first fixing jaw 462 and the second fixing jaw 464 are formed to correspond to the supporting piece 420, respectively, and are spaced apart by the thickness of the supporting piece 420 and are positioned between the fixing jaws 462 and 464. Secure 420. At this time, the protruding height of the first fixing jaw 462 is lower than the protruding height of the second fixing jaw 464, and the first fixing jaw 462 faces toward the outside, that is, the direction in which the support piece 420 approaches. The inclined surface is formed toward the. Therefore, when the support piece 420 is positioned between the fixed jaws 462 and 464, the end of the support piece 420 easily passes through the first fixed jaw 462 to allow the first and second fixed jaws 462 to pass. , 464).

Although the first fixing jaw 462 is lower than the second fixing jaw 464 in this embodiment and has an inclined surface, the present invention is not limited thereto, and the shape of the fixing jaw, the size between the corresponding fixing jaws and the formation of the inclined surface are those skilled in the art. If it can be variously modified and changed within the scope and spirit of the present invention.

A hole 430 is formed at the boundary of the third wall 413 and the indented third wall 413a or at the boundary of the fourth wall 414 and the indented fourth wall 414a. The hole 430 is for minimizing the contact area between the packing buffer 400 and the packaged object (not shown), and to improve the cushioning by the indented third and fourth walls 413a and 414a. .

A second side support plate 450 corresponding to the L-shaped space provided by the walls is disposed on one side of the body, so that the second side support plate 450 has an L-shaped shape corresponding to the shape of the adjacent body. Have The second side support plate 450 is inserted to a predetermined depth from the side of the adjacent body to support the surrounding walls 411, 412, 413, 413a, 414a, 414 therein. In addition, five auxiliary pieces 451, 452, 453, 454, 445 are connected to the sides of the second side support plate 450 via a fold line, and four auxiliary pieces 451, 452, 453 and 454 correspond to the first to fourth walls 411, 412, 413, and 414, respectively, and the other auxiliary piece 455 is formed on a surface corresponding to the indented fourth wall 414a.

The second side support plate 450 and the auxiliary pieces 451, 452, 453, 454, and 455 are inserted into the side of the body so that the first to fourth walls and the indented fourth walls 411, 412, 413, 414, 414a ), In particular the auxiliary pieces 451, 452, 453, 454, 455 maintain the position of the second side support plate 450 and respectively the inner surface of the corresponding walls 411, 412, 413, 414, 414a. Support it stably.

The first side support plate 440 is disposed on the other side of the body to face the second side support plate 450, and the auxiliary pieces 441, 442, 443, 444, and 445 are connected to the first side support plate 440. do. These first side support plates 440 and the auxiliary pieces 441, 442, 443, 444 and 445 are symmetrical with the second side support plates 450 and the auxiliary pieces 451, 452, 453, 454 and 455. In response. Accordingly, the description of the first side support plate 440 and its auxiliary pieces 451, 452, 453, 454, and 455 refer to the above description, and the descriptions thereof are omitted.

According to the present invention, compared with the conventional manufacturing method of manufacturing a buffer material by stacking a layer of paper, the packaging buffer material according to the present invention has the same size and sufficient strength required for packaging, as well as the consumption of the corrugated cardboard or other plate used Can be significantly reduced.

In addition, the cushioning material for packaging according to the present invention is light, can be stored folded and occupy a small space, even if stored as a box, easy to install and disassemble.

As described above, the present invention has been described with reference to the preferred embodiment of the present invention, but those skilled in the art can variously modify and devise the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
