Description

[Detailed description of the invention] (Field of industrial application) This invention relates to cushioning materials for packaging, and more specifically, when storing multiple bottles together in an external case, it is possible to isolate individual bottles and provide good cushioning. It concerns the cushioning material for protection.

(Prior art) Conventionally, when transporting and storing 1-sho bottles of sake or soy sauce, etc., grid-like partitions are placed vertically and horizontally inside a framed wooden box, and the bottles are placed in each compartment. I inserted and used it. However, wooden boxes and partition plates are hard and have poor cushioning properties for bottles, and there is also a gap between the partition plate and the bottles, which can rattle or collide during transportation, causing noise and damage to the bottles. I was getting used to it.

In order to solve the above problem, it has been proposed to insert a cushioning partition material such as a foamed polystyrene sheet between the bottles in the wooden box instead of the wooden partition plate.

For example, in the prior art disclosed in Japanese Utility Model Publication No. 49-29988, a plate-shaped cushioning material that is folded in half with a certain gap is formed with an uneven shape that follows the outer shape of the bottle. The cushioning material is inserted between the rows of bottles to protect the bottles.

However, when the left and right cushioning materials are folded in half and have a gap in the middle, they are pushed by the bottle during use, bending or deforming toward the center gap, and can no longer provide sufficient cushioning performance. There was a problem in that it allowed people to move, and an improvement was desired.

Furthermore, with the above-mentioned cushioning material, only the central semicircular part of the side surface of the body of the bottle comes into contact with the cushioning material, and the bottom of the bottle and the outer semicircular part of the body remain completely exposed and directly contact the cushioning material. It is in contact with the wooden box. Therefore, even if the cushioning material provides some protection against damage caused by collisions between bottles, the protection performance against external forces and impacts applied during transportation is insufficient, and further improvements are needed.

(Purpose and Structure) Therefore, the purpose of this invention is to provide a cushioning material that improves the above-mentioned sheet partition cushioning material and further improves the cushioning and protection performance for stored items such as bottles. The structure is generally flat, with the left and right inner plates facing each other with a narrow top plate in between, and the outer ends of both inner plates having a Each bottom plate and outer plate are connected in sequence, and the inner plate, bottom plate, and outer plate are bent freely so that they form a U-shape on the outside of the inner plate, and the outer surface of the inner plate is used to store bottles, etc. The left and right inner plates have symmetrically formed protrusions that can abut against the outer shape of the object, and furthermore, the backs of both inner plates have supporting protrusions that come into contact with the backs of the other inner plates during assembly. , is characterized by being formed at different positions on the left and right inner plates.

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

FIGS. 1 to 4 show the cushioning material 1 in an expanded state, which has a substantially rectangular flat plate shape as a whole and is formed by sheet forming such as vacuum forming from a foamed polystyrene sheet or the like.

The cushioning material 1 has two rectangular inner plates 10 and 20 on the left and right, which are integrally connected to each other via a narrow strip-shaped top plate 30 in the center.
V-shaped bending grooves 40 are formed on the back surfaces of the parts where 0 and both inner plates 10 and 20 are connected, respectively.
The left and right inner plates 10 and 20 are bendable at right angles to the top plate 30 so that the inner plates 10 and 20 face each other in parallel.

Further, bottom plates 50, 60 and outer plates 70, 80 are sequentially provided at the outer ends of the left and right inner plates 10, 20, respectively, and each component piece 10, 20, 50, 6
V-shaped bending grooves 90 are formed on the upper surface side of the cushioning material 1 at the locations where the 0, 70, and 80 are connected to each other.

The inner plate 10, the bottom plate 50, and the outer plate 70, which form one set on one side, can be bent freely to form a U-shape, and the inner plate 2, which forms one set on the other side.
0, the same applies to the bottom plate 60 and the outer plate 80. Therefore, the entire cushioning material 1 can have two sets of U-shaped storage parts on the left and right sides with the top plate 30 at the center.

In addition, as the bending groove 40 and the bending groove 90,
As long as each plate on both sides can be bent at a substantially right angle, it may be a V-shaped groove, a linear or U-shaped groove, or a bending groove 40 or 9 formed at one continuous location.
The number of zeros may be one, or may be two or three or more.

Next, on the upper surfaces of the inner plates 10 and 20, convex portions 11 and 21 each having an arcuate curved side wall approximately follow the outer shape of only one semicircular portion of the outer shape of the body portion of the bottle B or the like to be stored. is formed in a bulge along the width direction of the inner plates 10, 20. This convex portion 11, 2
1 is formed in such a manner that it tapers upward from the short side ends of the inner plates 10 and 20, and
Further, the centers of the upper ends of the convex portions 11 and 21 are formed with triangular recesses 13 and 23.

The convex portions 11 and 21 are arranged on the inner plate 10,
A plurality of bottles (six in the figure) are lined up at regular intervals along the longitudinal direction of the bottle 20, and the bottle B is inserted between two adjacent convex portions 11 and 21 for use. Therefore, with respect to the convex portions 11 and 21 formed at both ends of the inner plates 10 and 20, only the inner arcuate side walls are formed, and the height is a little lower than the others, and the concave portion at the center of the upper end is formed. 13 and 23 are also not formed.

In addition, in the left and right inner plates 10, 20, the shapes and formation positions of the convex portions 11, 21 are completely symmetrical. Further, the shape and number of the convex portions 11 and 21 are changed as appropriate depending on the shape of the bottle B to be stored and the shape and size of the outer case C such as a wooden box to be used.

Furthermore, among the inner plates 10 and 20, the convex portion 1
Supporting convex portions 12 and 22 are formed in the middle of 1 and 21 in the shape of a rectangular trapezoid and protrude toward the back side. One or more of the protrusions 12, 22 are formed along the width direction of the inner plates 10, 20, and the protrusions 12, 22 are formed between the left and right inner plates 10 and 20.
The formation positions of the two are asymmetrically arranged at different positions. That is, in the illustrated example, one inner plate 10 has two convex portions 12, upper and lower, spaced apart from each other by a certain distance.
, and the other inner plate 20 has the convex portion 12
One protrusion 22 is formed at a position intermediate between the formation positions.

The height of each supporting convex portion 12, 22 is determined by bending the cushioning material 1 into a U-shape, and
The supporting projections 12 and 22 are formed at a height such that the projections 12 or 22 come into contact with the back surface of the inner plate 20 or 10 on the other side when the 0s are faced to each other.
The height varies depending on the width of the top plate 30 of the cushioning material 1. In addition to the shape shown in the drawings, the support protrusions 12 and 22 may have a circular trapezoidal shape or other shapes, and the positions and number of the protrusions 12 and 22 formed can also be changed freely.

Next, on the upper surfaces of the bottom plates 50, 60, relatively low convex portions 51, 61 having side walls having an arcuate planar shape and substantially following the shape of the bottom side surface of the bottle B etc. are formed. However, the convex portions 51 and 61 at both ends of the bottom plates 50 and 60 are formed in a half-shape having only one arcuate side wall. Further, in the center of the convex portions 51, 61 of the bottom plates 50, 60, disc-shaped flat convex portions 52, 62 are formed to follow the shape of the bottom concave portion of the bottle B or the like.

Next, on the upper surface of the outer plates 70 and 80, the inner plate 1
Convex portions 71, 81 and upper end recessed portions 73, 83 are formed symmetrically with respect to 0, 20, and supporting convex portions 72, 82 are formed on the back surface. However, the convex portions 72, 82 are one convex portion 72, which is continuous over the entire length of the outer plates 70, 80 in the transverse direction.
82 are formed respectively.

As the material for forming the above-mentioned cushioning material 1, a foamed sheet made of various thermoplastic resins such as polystyrene is suitable in terms of cushioning properties and light weight. A multilayer sheet made of laminated sheets can also be used. It is also possible to use molded products made of various sheet materials such as non-foamed thermoplastic resin sheets and pulp molded products.

Next, as a method of using the above-mentioned cushioning material 1, the fifth method is as follows.
6 and 6, the cushioning material 1 in the unfolded state is first placed between the inner plates 10 and 20 on the left and right sides of the top plate 30.
are bent so that they face parallel to each other, and further the bottom plate 5
0, 60 and the outer plates 70, 80 are sequentially bent into a U-shape. At this time, the inner plates 10, 20
On the back side, the supporting protrusions 12 and 22 are assembled in a state where they are offset from each other, and the tip of the protrusion 12 is in contact with the back side of the inner plate 20 on the other side, and the tip of the protrusion 22 is in contact with the inner plate 20. It comes into contact with the back side of 10.

Then, the convex portions 11 and 2 of the inner plates 10 and 20
1. Convex portions 51, 61, 5 of bottom plates 50, 60
2, 62 and the convex portions 71 of the outer plates 70, 80,
In the storage space surrounded by 81, each bottle B is 1 sho.
are inserted one by one. Therefore, the bottle B is stored and protected with its entire side wall and bottom surface in contact with the cushioning material 1.

In this way, the cushioning material 1 containing the bottle B is stored in an exterior case C such as a wooden box for transportation and storage. However, the wooden box serving as the outer case 6 may not be provided with vertical and horizontal lattice-like partitions inside as in the conventional case, but may be constructed simply of an outer peripheral frame.

In the outer case C such as a wooden box, the supporting convex portions 7 formed on the outer plates 70 and 80 of the cushioning material 1
2 and 82 come into contact with the inner wall of the outer case C, and the bottle B
A certain gap is left between the bottle B and the outer case C, making it difficult for the influence of external forces to be directly transmitted to the bottle B, thereby increasing the cushioning properties.

In addition to a wooden box, the outer case C used is a wooden box.
Hard synthetic resin or cardboard can also be used. Furthermore, as the bottle B, in addition to relatively large bottles such as 1-sho bottles of sake and soy sauce, beer bottles, soft drink bottles, and other various glass bottles can also be used. Moreover, the cushioning material 1 of this invention can also be used for storing cylindrical articles made of ceramics, synthetic resin, metal, or the like.

When transporting and storing the cushioning materials 1 alone, the cushioning materials 1 can be handled in a flat unfolded state and stacked on top of each other.

Among the cushioning materials 1 described above, the bottom plates 50 and 6
Regarding the convex portions 51, 61, 52, 62 of 0 or the convex portions 71, 81 of the outer plates 70, 80 and the supporting convex portions 72, 82, even if some or all of them are omitted, the inner plate 10, The convex portions 11 and 21 of 20 can fix the position of the bottle B and have a buffer protection effect, so it can be used (see Fig. 7), but a more complete position fixation and buffer protection performance can be achieved. For this reason, the embodiments shown in FIGS. 1 to 6 are preferable.

Regarding the outer plates 70 and 80, the inner plate 1
If the inner plates 10 and 20 are formed to the same height, the buffer protection performance will be the best, but even if the height is halfway between the inner plates 10 and 20, the positioning of bottle B and buffer protection can be achieved. . In this case, the outer plates 70, 8
The convex portions 71, 81 and the supporting convex portions 72, 82 formed at 0 have a half shape with the upper half cut off (see FIG. 8).

(Effects) According to the cushioning material 1 of this invention described above,
Inner plate 10 with stored items such as bottle B bent into a U-shape,
20, bottom plate 50, 60 and outer plate 70, 80
Because it comes into contact with three sides to protect storage, the buffer protection performance is much improved compared to the conventional case where only the inner plate contacts only one side of Bottle B to protect storage. do. That is, the outer case C
External forces such as shocks and vibrations applied to the bottle B do not directly act on the bottle B, and the bottom plates 50, 60 and the outer plates 70, 70 of the cushioning material 1.
80, the protection against external forces is extremely excellent. Therefore, it is particularly suitable for storing various types of bottles, from large bottles such as 1-sho bottles that are relatively heavy and subject to rough handling, to small bottles that are thin and break easily, and other items that are fragile or easily damaged. becomes.

In addition, the problem of bottle B moving or shaking can also be caused by bottle B
By having three sides of the bottle B in contact with the cushioning material 1 to restrict its movement, the bottle B can be reliably fixed in position, which is also highly effective in preventing vibration and noise.

Further, support protrusions 12 and 22 are formed on the back surfaces of the inner plates 10 and 20, and when used assemble, the support protrusions 12 and 22 are placed in the opposite positions of the inner plates 20 and 20 of the other side, respectively. 10, so that the left and right inner plates 10 and 20 can be maintained at a constant distance from each other. And the inner plate 10,
20 can be maintained sufficiently, the rows of bottles B, etc. on both sides are connected to the convex parts 11, 21 and the outer plate 7.
0.0, 80, and the inner plates 10, 20 can be securely held in position between 0.0 and 80 degrees. Therefore, problems such as the narrowing of the distance between the inner plates 10 and 20 can be solved, and the positioning and buffering protection performance of the bottle B etc. can be further improved.

The presence of the top plate 30 also greatly helps in maintaining the distance between the inner plates 10 and 20. That is, the top plate 30 acts as a kind of support above the left and right inner plates 10 and 20, and the distance between the inner plates 10 and 20 can be reliably maintained at a constant distance that is approximately the same as the width of the top plate 30.

Furthermore, the cushioning material 1 includes inner plates 10 and 20, a top plate 30, bottom plates 50 and 60, and outer plates 70 and 80.
are all connected in one piece and are used by folding and assembling at the bending grooves 40, 90, etc., so it is easy to mold and manufacture in the unfolded state, and when transporting and storing only the cushioning material 1, it is possible to A large number of materials 1 can be piled up for compact storage and transportation. Furthermore, it has various excellent practical values, such as being easy to use by simply folding and assembling, and being easy to handle.
