Description

[Detailed Description of the Invention] This invention relates to a shock-absorbing package, and aims to provide a packaged object consisting of a main article and an accessory article that has good cushioning properties and can be compactly and easily packaged.

Traditionally, the main products were electrical products such as small radios,
When packaging items that include parts such as batteries as accessories, wrap the main item and accessories separately in foam sheets or paper boxes, and then place them inside a tray-shaped cushioning material. This was then packaged in an outer case such as a cosmetic case.

However, the above-mentioned packaging method is very time-consuming, requires considerable cost for packaging materials, and tends to waste space, resulting in poor storage efficiency.Therefore, an improvement has been desired.

It is also possible to use a non-foamed resin sheet molded product in which storage recesses are formed in advance to match the external shape of each item, and to store the items in each recess. In addition to being cumbersome to manufacture, the cushioning protection for the top surface of the product is not sufficient, and since it is necessary to provide a certain distance between each recess, there are also problems in terms of storage efficiency.

Therefore, the purpose of this invention is to provide a buffer packaging body that can eliminate the above-mentioned drawbacks and inconveniences of the conventional technology.As for its structure, the entire body is integrally molded from a synthetic resin sheet, and the main body along the longitudinal direction A main article storage part component piece consisting of a side piece, a side piece, and a main piece, and an accessory article storage part component piece consisting of a side piece, a top piece, and a middle piece are successively connected to each other so as to be freely foldable,
The main article storage section component piece can be assembled by bending each piece so that both main pieces face each other, and the accessory article storage section component piece has side pieces and middle pieces facing each other. Each piece is bent so that the accessory storage part can be assembled, and each piece is formed with at least one protrusion that abuts along the outer shape of the storage item. The supporting protrusions provided at corresponding locations on both main body pieces of the component part and at corresponding locations on the side pieces and middle piece of the accessory storage part component piece are formed so as to abut each other. It is characterized by the presence of

Next, embodiments of this invention will be illustrated below with reference to the drawings.

FIG. 1 is a perspective view showing the cushioning package according to this invention, and 1 in the figure shows the whole, which is made of a synthetic resin sheet such as a foamed polystyrene sheet by sheet forming means such as vacuum forming. It is shaped like a rectangular plate.

The buffer package 1 includes, along the longitudinal direction, a relatively wide rectangular main body piece 10, a relatively narrow elongated side piece 20, and a main body piece 30 similar to the main body piece 10 described above. The main article storage section component a and the accessory article storage section component b, each consisting of a side piece 40, a top piece 50, and a middle piece 60, each of which is a relatively narrow elongated piece, are arranged in a V-shape at their mutual boundary. They are integrally connected via a shaped bending groove 70.

Then, each piece of the main article storage section component a is successively bent at right angles, and assembled into a large square frame shape so that the two main body pieces 10 and 30 face each other to form the main article storage section A, and the attached articles Each piece of the storage section component b is successively bent at right angles and assembled into a small square frame shape so that the side pieces 40 and the middle piece 60 face each other, and assembled so as to fit between the main body pieces 10 and 30. It can be used as an accessory storage section B (see FIGS. 2 and 3).

Next, in the main body pieces 10 and 30, the protrusions 11, 11, 31, 31 formed in the longitudinal direction expand two protrusions on each piece toward the side that will become the inside when the buffer package 1 is assembled. The protrusions 11, 11 of the main body piece 10 and the protrusions 31, 31 of the main body piece 30 are provided symmetrically to each other, so that both the main body pieces 10, 30 face each other. When the shock absorbing package 1 is assembled, the protrusions 11, 11 are arranged so that they face each other at the same position, and the tips of the protrusions 11, 11 and 31, 31 are exactly in contact with each other. ,31,3
It forms a height of 1. In the illustrated embodiment, the protrusions 11, 11 and 31, 31 are formed to have the same height to facilitate manufacturing and handling.
As long as the tips of the protrusions 31 can come into contact with each other, the heights of the protrusions do not necessarily have to be the same.

Of course, the shape of each protrusion 11, 11, 31, 31 differs depending on the article to be stored, but for example, in FIGS. This shows a case where a small radio C is stored, and the protrusion 1 has its tips abutting each other at a portion near one of the long end surfaces of the buffer package 1.
1 and 31, and protrusions 11 and 31 whose tips abut each other at a portion near the other of the long ends, so that the top and bottom surfaces of the small radio C are formed along the inner sides thereof.

Further, 12, 12, 32, 32 are the buffer packaging body 1
When the small radio C is assembled and stored, the main body piece 10 is placed along the front and back sides of the small radio C.
Two rib convex strips are formed on each of the ribs 30, and are designed to abut against the front and back surfaces of the small radio C, which requires cushioning protection against shocks, etc., to provide good protection.

Furthermore, rib protrusions 13 and 33 are provided on the main body pieces 10 and 30 in a direction perpendicular to the longitudinal direction at mutually symmetrical positions with the side piece 20 as the center, and the rib protrusion 13 of these is provided in the direction perpendicular to the longitudinal direction. In order to lock the top piece 50 to the top piece 50, the other rib convex line 33
is used to contact and protect one of the batteries D stored in the accessory storage section B.

Next, in the side member 20, 21, 21 are two rib protrusions formed in the longitudinal direction of the buffer package 1, and are effective for reinforcing the side member 20. Further, protrusions 22, 22 are formed in a direction perpendicular to the direction in which the rib protrusions 21, 21 are formed, and are slightly lower in height and shorter in length than the protrusions 11, 11, 31, 31. This abuts against one side of the small radio C to provide good protection.

Now, the main article storage section component a is constructed as described above, but the accessory article storage section component b is composed of the side piece 40, the top piece 50, and the middle piece 6, which are configured as follows.
Starting from 0.

First, the side piece 40 is entirely bulged toward the side that will become the inside when the buffer package 1 is assembled, and both ends thereof form protrusions 41, 41 having particularly high heights. The middle portion thereof is a bulge portion 42 having a slightly lower height.

Next, in the center of the top piece 50, a bulge part 51 is formed so as to be biased toward the middle piece 60 side, and this bulge part 51 comes into contact with one of the batteries D stored in the accessory storage part B. used for protection. Furthermore, the bulging portion 51 is a concave portion when viewed from the back side,
The concave portion is used to engage the rib protrusion 13 of the main body piece 10 and to lock the main body piece 1 to the top piece 50.

Next, the middle piece 60 has protrusions 61 whose height is slightly lower than the protrusions 41, 41 of the side pieces 40 at positions corresponding to the protrusions 41, 41 of the side pieces 40 when the buffer package 1 is assembled.
61 is bulge-molded, and the tips of the protrusions 41, 41 and 61, 61 are brought into close contact with each other when assembled. Moreover, between the protrusions 41, 61 and 41, 61 that come into contact with each other in this way, the space surrounded by the rib protrusion 33, the bulges 42, 51, and the inner wall of the middle piece 60 is used for storing the accessories mentioned above. Part B is designed to accommodate two batteries D and D.

The cushioning packaging material 1 described above is assembled into a frame shape, a small radio C is stored in the main item storage area A, and two batteries D and D are stored in the accessory item storage area B, and then, for example, with cardboard, etc. It is used by being inserted into an outer case (not shown) that is shaped like a flat rectangular tube. In addition to combining with the above-mentioned outer case, it can also be used in combination with conventional paper boxes, packaging bags, and other outer packaging materials, and it is also possible to combine multiple cushioning packages 1 containing articles into one outer box. It is also possible to store it. Furthermore, the entire buffer package 1 may be covered with a heat-shrinkable film and the film may be heat-shrinked to closely cover the entire buffer package 1, so-called shrink-coated packaging.

Next, as the synthetic resin sheet forming the buffer package 1, foamed or non-foamed sheets of various synthetic resins conventionally used as packaging materials can be used, but particularly preferred ones include, for example, butadiene-containing sheets. There are highly polymerized foamed polystyrene sheets, and relatively hard foamed sheets such as foamed polystyrene sheets, and relatively soft foamed sheets such as polyolefin foamed sheets such as foamed polyethylene sheets and foamed polypropylene sheets, which use EVA as a binder. A multilayer sheet laminated with a polyester resin is suitable as it has both rigidity and flexibility, and a non-foamed sheet made of a resin such as high-impact polystyrene, polypropylene, or polyvinyl chloride and a relatively soft foamed sheet mentioned above are suitable. A multi-layer sheet in which these are laminated together is also a preferred implementation.

In addition, when using a multilayer sheet as described above, the flexible sheet side shall be used as the surface that comes into contact with the stored articles. Furthermore, it is preferable to apply antistatic treatment to each of the synthetic resin sheets, since this is effective in preventing the adhesion of dirt and dust.

Items to be packaged that can be packaged with the buffer package 1 of this invention include the aforementioned small radio C and its two accessories, D and D, as well as various precision electrical products, toys, ceramics, and glass. Products, etc. can be considered.

According to the buffer package 1 of this invention configured as described above, the main article such as a small radio C is stored in the main article storage section A, and the battery D, etc. is stored in the accessory article storage section B.
It is possible to store accessories such as D and hold them with good cushioning properties.

In the main article storage section A, the main piece 10
The protrusions 11, 11 of and the protrusions 31 of the main body piece 30,
Since the tips of the main body pieces 10 and 31 are brought into contact with each other, the gap between the two main body pieces 10 and 30 can be maintained appropriately. Therefore, the main items such as the small radio C stored therein can be protected with good cushioning properties.

Also, in the accessory storage section B, the protrusions 41, 41 of the side pieces 40 and the protrusions 61, 61 of the middle piece 60
Since the tips of the two are in contact with each other, the gap between the side piece 40 and the middle piece 60 can be maintained appropriately. Therefore, accessories such as batteries D and D stored therein can be protected with good cushioning properties.

Furthermore, even if the individual protrusions 11, 31, 41, 61 have a relatively simple shape, by appropriately arranging them, they can come into contact with and protect the stored articles at appropriate locations. It is much easier to manufacture and less expensive than the conventional method in which a storage recess is formed along the entire shape of the article.

Moreover, the conventional method of forming storage recesses has the drawback that when storing multiple items as in this invention, the recesses cannot be formed unless an appropriate space is provided between each storage recess, and the cushioning performance deteriorates. However, according to the shock-absorbing package formed with protrusions as in this invention, if the protrusions are formed only in areas where there is sufficient space between each article, it is possible to protect the main articles with sufficient cushioning properties. It is possible to compactly store a plurality of items including the accessories and accessories in a minimum space, resulting in excellent storage efficiency.

In addition, the buffer package 1 itself is made up of a single sheet-like piece with each piece connected together, which is folded and assembled, so it can be easily manufactured using a normal sheet-forming method and is easy to transport. , and easy to store.

Therefore, according to this invention, it is possible to package the packaged items consisting of the main article and accessory articles in a compact manner with good cushioning properties using a single cushioning package, and the packaging operation is very simple.Moreover, it is easy and inexpensive to manufacture. A cushioning package is provided that can exhibit various excellent practical effects such as.
