Description

  The present invention is a cushioning material for preventing a product from being damaged even when the product being delivered is dropped or bumped when the product is transported or delivered by a courier or the like. In particular, the present invention relates to a cushioning material that can further protect the parts of the material that are easily damaged even when a material that is easily damaged such as glass is used for a part of the delivery.

Traditionally, mail order companies use courier services to deliver large quantities of products to customers who are orderers.
Some of these products are made of materials that are easily damaged, such as glass, so if you accidentally drop or bump these products during delivery However, in order to prevent the product from being damaged, it is protected by putting a material called a cushioning material in the gap.
Regarding these buffer materials, buffer materials having various structures are already known. (For example, see Patent Documents 1 to 5)

JP-A-6-171671 JP-A-7-206047 JP-A-8-143065 JP 2002-255157 A JP 2005-75380 A

These cushioning materials must be made of materials and structures with strong and / or high buffering effect (such as irregular shapes), especially to protect easily damaged materials such as glass. It is a cost burden.
Furthermore, since the cushioning material becomes unnecessary after the product is delivered, and most of it is discarded, there is a problem in terms of wasteful use of resources.

  Therefore, the present invention makes it possible to more strongly protect a particularly fragile portion such as a glass surface even when a part to be delivered has a fragile material such as glass, and eliminates unnecessary cost burden. Further, the present invention provides a cushioning material that can be improved in terms of wasteful use of resources.

  In order to achieve the above object, the cushioning material of the present invention is repeatedly folded by a plurality of parallel folding portions to form two cushioning members each having a continuous uneven shape, and the top of the two cushioning members. The sheet-like base material includes a sheet-like base material that is overlapped and bonded to the sheet-like base material, and the sheet-like base material includes a folding target portion that folds the sheet-like base material in two when the article is wrapped with the buffer material The buffer member is superposed on each of the left and right sides of the planned folding portion, except for the planned folding portion, and each of the cushioning members is formed of a different material.

  Further, the cushioning material of the present invention is the cushioning member formed of the different material, the cushioning member on the side facing the fragile part of the delivery wrapped with the cushioning material, the material of the other cushioning member It is characterized by being formed using a material having a higher buffering effect and an uneven shape.

  Accordingly, the cushioning material of the present invention is formed of different materials for the cushioning member provided on one side and the cushioning member provided on the other side with respect to the planned bending portion of the sheet-like base material. Even if the article is wrapped in cushioning material, even if the article contains a fragile material, it can be protected using a stronger material at the position facing the fragile material part. By using a material of normal strength for this part, particularly fragile parts can be protected more strongly, and there is an effect that wasteful cost burden can be eliminated and waste can be saved economically.

  Furthermore, even if the cushioning material of the present invention has a fragile portion such as glass on the outer surface of the article to be delivered, the cushioning member on the side facing the fragile portion is more cushioning than the material of the other cushioning members. Can be protected with high-quality materials and uneven shapes, so it can be delivered with peace of mind even when articles with a glass surface are delivered, and materials other than fragile parts such as glass have normal strength materials By using, even if an article to be delivered is fragile, only the fragile part can be more strongly protected, and there is an effect that it can be improved in terms of wasteful use of resources.

Hereinafter, a buffer material according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a cushioning material according to an embodiment of the present invention, FIG. 2 is a diagram showing a cushioning member and a sheet-like base material constituting the cushioning material according to the embodiment of the present invention, and FIG. 1 is a cross-sectional view taken along line A-A, and FIG. 4 is a diagram illustrating a state in which a delivery item is wrapped using the cushioning material according to the embodiment of the present invention.

As shown in FIG. 1 to FIG. 3, the cushioning material 1 according to the embodiment of the present invention is repeatedly folded by a plurality of parallel folding portions and has two cushioning members 2 a and 2 b each having a continuous uneven shape. The sheet-like base material 3 is superposed on and bonded to the two cushioning members 2a and 2b.
Further, the single sheet-like base material 3 has a planned folding portion 5 for folding in half when the article is wrapped with the cushioning material 1, and the two cushioning members 2a and 2b are provided in the vicinity of the center. The sheet-like base material 3 is provided by being adhered to the left and right regions excluding the region of the planned bending portion 5 on the back surface side.
Thus, even when the article to be delivered is sandwiched between the two folded cushioning materials 1 and packaged, the sheet-like base material can be easily folded at the planned folding portion 5, and the cushioning members 2a and 2b It is configured not to be disturbed.

Further, the surface of the sheet-like substrate 3 has an information display unit 4 on which a person who delivers articles using the cushioning material 1 freely displays desired characters, images, and the like.
The information displayed on the information display unit 4 includes, for example, an address and name that are destination information of an article to be wrapped and delivered by the cushioning material 1, information transmitted to a recipient of the delivered article, Various displays such as company names, product names, and advertisements are displayed.
By displaying these patterns and images on the surface of the sheet-like substrate 3 by printing or the like, the same design effect as that of wrapping the article with wrapping paper can be expected.
As described above, the information display unit 4 may display various contents freely by a company using the cushioning material 1, for example, display advertisement information such as a company's sales products and services. Can also be expected to promote advertising.

As shown in FIG. 3, each buffer member 2a, 2b has a sheet-like base material that is repeatedly bent to form regular uneven portions, and a flat portion is provided in the vicinity of the vertex of the convex portion. Since it is shaped, it has strip-shaped flat portions at equal intervals on the upper side of the buffer members 2a and 2b, and linear corners at equal intervals on the lower side of the buffer members 2a and 2b. .
Thereby, the back surface of the sheet-like base material 3 is superimposed on the surface of the flat portion of the two buffering members 2a and 2b, and the sheet is bonded with the adhesive 6 applied to the surface of the flat portion of the buffering members 2a and 2b. It is bonded and integrated with the back surface of the substrate 3.

The size of the linear corner formed below the two buffer members 2a and 2b can be various dimensional sizes.
Further, the size of the corners may be arbitrarily set as long as it is selected according to the material of the article to be wrapped using the cushioning material 1.
For example, if the article to be wrapped with the cushioning material 1 is a material that is vulnerable to impacts such as glass objects, it is structured so that the zigzag depth is increased and delivered at the time of delivery. Even if the product is accidentally dropped or bumped, the impact will not be transmitted directly to the product.If the product is made of a material that is resistant to impact, the zigzag shape should be shallow. It can be adjusted by reducing the material cost.

The sheet-like base material 3 and the two buffering members 2a and 2b are made of synthetic resin having degradability in the natural environment, or paper made of natural pulp as a raw material. About the members 2a and 2b, the buffer member 2a provided on one side with respect to the planned bending portion 5 and the buffer member 2b provided on the other side are formed of different materials.
In this case, among the cushioning members formed of different materials, when the cushioning material 1 is folded in half and the article 7 is wrapped, the one side of the article has a fragile part like a glass surface, The buffer member on the side facing the glass surface is formed of a material having a stronger strength than the material of the other buffer members.
Therefore, in the case where a material that is easily broken against an impact such as a glass surface is used on one side of the article, it has a structure that can protect a portion of the material that is particularly easily broken than the other portion.
Therefore, the portions other than the material that is easily destroyed are made of another inexpensive material.

For example, FIG. 4 shows, as an example, a state in which an article 7 that is a frame having a glass surface on one side is sandwiched between two folded cushioning materials 1, but in this case, the article 7 The cushioning member 2a facing the glass surface 7a is formed of a strong material made of a synthetic resin, and the cushioning member 2b facing the edge portion on the back side not facing the glass surface 7a is used with paper, In addition to protecting particularly fragile parts such as the glass surface of No. 7, the parts that protect the edge of the frame, which is a part that is resistant to impact, are made of a material with low material costs, so there is no unnecessary cost burden. It is like that.
Then, in a state where the article 7 is sandwiched between the cushioning materials 1, the product 7 is sealed in a envelope or a bag for delivery.

It is a perspective view of the shock absorbing material which concerns on embodiment of this invention. It is a figure which shows the buffer member and sheet-like base material which comprise the buffer material which concerns on embodiment of this invention. It is the sectional view on the AA line of FIG. It is a figure explaining the state which wraps a delivery thing using the shock absorbing material which concerns on embodiment of this invention.
