Description

[Detailed description of the invention] (Industrial application field) This invention is for packaging products wrapped in appropriate wrapping paper such as vinyl or Hatron paper, or unwrapped products in an outer box such as a cardboard box. This relates to a cushioning member that is inserted between a product and an outer box, etc., to prevent friction between the product and the outer box, and to protect the product by absorbing and mitigating external shock.

(Prior art) Conventionally, synthetic resin cushioning material is incorporated into the four corners of the cardboard box that serves as the outer box, and the target product is placed on top of the cushioning material. In order to avoid direct contact with the cushioning material, it is necessary to appropriately insert inner paper, inner mount paper, etc. between the cushioning material and the product.

Therefore, in the past, synthetic resin cushioning materials were placed in advance at the four corners of the outer box, and then the inner mount, etc., was carefully dropped from above, or synthetic resin cushioning materials were placed in advance on the outside of the four corners of the inner mount, etc. It was glued.

(Problem that the invention aims to solve) However, the method of installing cushioning material inside the outer box in advance is troublesome because the inner mount etc. must be carefully placed in line with the corner of the cushioning material on the bottom of the outer box. be. On the other hand, the method of adhering the cushioning material to the inner mount or the like is not always satisfactory, as it takes time for adhesion and drying.

Therefore, for example, a method of sandwiching the inner mount with cushioning material as devised in Utility Model Application Publication No. 58-102474 can be considered.
Mere clamping does not provide a fundamental solution because the cushioning material and the surface of the product still come into direct contact.

Therefore, the problem is how to integrate the cushioning material, the inner mount, etc.

(Means for solving the problem) This invention was created in response to such a request, and includes a horizontal piece, a side wall provided perpendicularly to an appropriate piece of the horizontal piece, and a side wall other than the above-mentioned appropriate pieces of the horizontal piece. A cushioning material consisting of a bendable bottom piece provided on one side, and provided with means on the back side of the horizontal piece and means for fitting each other when the bottom piece is bent and abuts on the back side of the horizontal piece; It consists of a bottom piece and a mount consisting of sides that stand up from the periphery of the bottom.
A notch is made in a part of the bottom of the mount to provide a bendable piece that can be bent downward, and a hole is bored in this bending piece through which a fitting means of the cushioning material, such as a protrusion between a protrusion and a hole, is inserted.
Bring the horizontal piece of the cushioning material into contact with the back of the bottom of the mount, then bend the folded piece of the mount and bring it into contact with the back of the horizontal piece, then bend the bottom of the cushioning material and place the bent piece of the mount horizontally on the cushioning material. It is held between a piece and a bottom piece.

(Function) The mount referred to in the configuration of this invention corresponds to the "middle mount", and by sandwiching the folded piece of the mount between the horizontal piece and the bottom piece of the cushioning material, the mount, that is, the middle mount, is integrated with the cushioning material. Ru. Note that the material for the mount may be those conventionally generally used as inner paper or inner mount, such as cardboard, cardboard, or other materials.

In addition, when integrated, the side wall surface of the cushioning material is covered by the side surface of the mount, and the horizontal side surface is covered by the bottom surface of the mount, so stored items such as products do not come into direct contact with the cushioning material, which is different from conventional methods. It will come into contact with paper and the mount made of the material used as the inner mount. Therefore, the surface of the product etc. will not be damaged.

In addition, since the folded piece that is part of the mount is sandwiched between the horizontal piece and the bottom piece of the cushioning material, in addition to the original cushioning function of the cushioning material, the mount becomes double and the vertical This will provide a buffering function. In other words, the cushioning function is increased by the amount of the mount, that is, the inner mount, compared to the normal cushioning function of "buffer material + inner mount", and a so-called longitudinal cushion is added.

(Example) Hereinafter, one example will be explained with reference to the drawings.
FIG. 1 and FIG. 2 show the buffer member according to the example.
This is a diagram showing a cushioning material 1. As is clear from the diagram, this is used exclusively for corners and is made of elastic synthetic resin. A bottom piece 3 of the same shape and size is provided on the horizontal piece 2 having a core-shaped partition wall on the back side of the rectangle so that it can be bent freely via a folded part 4. Holes 5 are drilled in several places. On the other hand, on the back side of the bottom piece 3, when the bottom piece 3 is bent through the folded part 4 and comes into contact with the back side of the horizontal piece 2, a fitting hole with a shape corresponding to the hole 5 is provided at a position corresponding to the hole 5. The same number of protrusions 6 are provided.

Side walls 7 and 8 having core-shaped partition walls are vertically provided on both sides of the horizontal piece 2 other than the one on which the bottom piece 3 is provided, forming a right angle to the horizontal piece 2. On the other hand, as the middle mount in this embodiment, a mount 9 formed in a so-called tray shape with four erect sides is used, and at a corner on the bottom surface 9a of this mount 9, as shown in FIG. A cut 10a is left along the side plate 9b, a cut 10b is perpendicular to the cut 10a, and a cut 10c is made parallel to the cut 10a and perpendicular to the cut 10b, and folding lines 10d and 10e are provided as shown in the figure. A bent part 11 having the same shape and the same size as the side surface 2a of the horizontal piece 2 and a folded piece 12 having the same shape and the same size as the horizontal piece 2 are provided which are connected to this through a folding line 10e.

This bent piece 12 has the same number of holes 12a as the protrusions 6 at positions corresponding to the holes 5, each having a shape through which the protrusions 6 are inserted. That is, as shown in FIG.
is brought into contact with the outside corner of the mount 9, and the bent piece 12 is bent toward the back surface of the mount 9 along the folding lines 10d and 10e, and when it comes into contact with the back surface of the horizontal piece 2 of the cushioning material 1, The same number of holes 12a are drilled in the same positions as the holes 5 drilled in the back surface of the piece 2. The same process is performed on the other three corners of the mount 9.

This embodiment has the structure and configuration as described above, and when used, for example, referring to one corner shown in FIG. Place the piece 2 on the outside of the corner of the mount 9 so that it comes into contact with the back surface of the bottom plate 9a of the mount 9, and then bend the bent piece 12 along the bending lines 10d and 10e as described above to place it on the back side of the horizontal piece 2. Bring it into contact. Thereafter, as shown in FIG. 4, the bottom piece 3 is bent in the direction of the arrow in the figure via the bending portion 4, and brought into contact with the bending piece 12. That is, the folded piece 12 is placed on top of the bent piece 12 from the side 90 degrees off from the top, so that the bent piece 12 is sandwiched between the horizontal piece 2 and the bottom piece 3, and the protrusion 6 of the bottom piece 3 passes through the hole 12a of the bent piece 12 to the back side of the horizontal piece 2. It fits into the hole 5 drilled in the hole 5. The completion status is shown in Part 5.
As shown in the figure. Then, the cushioning material 1 is attached to the other corners of the mount 9 in the same manner.

Although the above embodiment uses the cushioning material 1 only at the corners of the mount 9, for example, as shown in FIG. , a cushioning material that can be used in the middle part is obtained, and by appropriately providing the above-mentioned bent pieces 12 in the middle part, it is possible to easily obtain a buffering material suitable for packaging objects to be packaged such as products with long sides. .

(Effects of the invention) As is clear from the examples, the cushioning member according to the invention can easily and reliably integrate the mount serving as the middle mount and the cushioning material, and no fixing agent such as adhesive is required. Therefore, the cushioning material, inner paper, inner mount, etc. can be quickly and easily set in the cardboard box serving as the outer box, improving work efficiency. Of course, the product does not come into direct contact with the cushioning material, so the surface will not be damaged.

Furthermore, a major feature of this invention is that the folded piece, which is a part of the mount, is held between the horizontal piece of the cushioning material and the bottom piece, so in addition to the original cushioning function of the cushioning material, the mount can also be used as a double-layer. It becomes heavy and exerts a buffering function in the vertical direction.

In other words, the cushioning function is increased by the amount of the mount, that is, the inner mount, compared to the normal cushioning function of "buffer material + inner mount", and a so-called longitudinal cushion is added. Therefore, by appropriately selecting the material of the mount, the vertical buffering function can be increased more than usual.

Furthermore, once one type of cushioning material is prepared, all that is required is to provide folded pieces in the same direction at the four corners of the mount, and there is no need for multiple types of cushioning materials. In other words, there is no so-called directionality and it is easy to use.
