Description

  The present invention relates to a storage container, and more particularly to a storage container that is suitable for storing various articles and can be folded.

Conventionally, cardboard boxes have been widely used as storage means for distributing various products to the market. However, since the cardboard box is made of paper, it is weak against water and is not suitable for packing a product containing a lot of moisture as it is.
On the other hand, foamed resin boxes made of foamed polystyrene are used for applications where water resistance and heat insulation are required, such as when fish shellfish are boxed with ice and refrigerated or frozen. However, such a foamed resin box cannot be folded like a corrugated cardboard box and is bulky, and therefore requires a lot of storage space when used.

  Therefore, for example, Patent Document 1 proposes a corrugated cardboard box assembled with such corrugated cardboard by imparting water resistance to the corrugated cardboard by bonding liners to both sides of the core core formed by corrugated core base paper. ing.

JP 2000-141518 A

  However, even when corrugated cardboard with water resistance is assembled into a cardboard box, there are gaps at the four corners of the bottom due to its structure. For this reason, there is a problem that water accumulated at the bottom leaks out and wets the surroundings. In Patent Document 1, in consideration of such a problem, an attempt is made to prevent water leakage by placing a moisture absorber at the bottom of the box.

In view of the above circumstances, the present inventors have water resistance, and even when water accumulates at the bottom, they do not leak out and can be folded so as not to be bulky. In order to obtain these alternatives that combine the advantages of conventional corrugated cardboard boxes and foamed resin boxes, such as requiring no space, we have made extensive studies.
The present invention is one of the results made in the process of such intensive studies by the present inventors. Water resistance is imparted as necessary so that water does not leak to the outside even if water accumulates at the bottom. It is an object of the present invention to provide a novel storage container that can be easily folded and is foldable and has excellent storability.

  The storage container according to the present invention includes a container body made of a flexible material and a reinforcing member that is detachably attached to the container body.

  According to the present invention, it is possible to provide a storage container that is foldable but has excellent shape retention by attaching and reinforcing a reinforcing member to a container body made of a flexible material. .

  Embodiments of the present invention will be described below with reference to the drawings.

[First embodiment]
First, the storage container which concerns on 1st embodiment of this invention is demonstrated with reference to FIGS.
1A and 1B are explanatory views showing an outline of a storage container according to the first embodiment of the present invention. FIG. 1A is a perspective view, and FIG. 1B is an A-A view of FIG. It is sectional drawing.

  As shown in FIG. 1 (a), the storage container 1 is a box-shaped container (in the illustrated example, a cubic shape) having an open top, a container main body 2 made of a flexible material, and the container main body. And four reinforcing members 3 for reinforcing 2.

The container body 2 has a side wall portion 21 and a bottom portion 22. In the present embodiment, the container body 2 is formed so as to stand up in a rectangular tube shape from the bottom portion 22 formed in a square shape and the periphery of the bottom portion 22. And the side wall portion 21.
The container body 2 is formed to have a double structure in which an outer layer member 23 and an inner layer member 24 each made of a flexible material are overlapped.

  As the flexible material forming the container body 2, various flexible materials can be used as long as the container body 2 is flexible enough to be foldable. For example, a film material or a sheet material made of a synthetic resin made of a polyolefin resin such as polypropylene or polyethylene, a polystyrene resin such as polystyrene, a polyester resin such as polyethylene terephthalate, or a polyamide resin such as nylon can be exemplified. . Such a flexible material made of a synthetic resin may be a single layer structure or a multilayer structure in which the above resin materials are combined, and further, a metal using aluminum or the like for providing light shielding properties and heat insulating properties. Although a vapor deposition film layer may be laminated, it is preferably a material that can be heat-sealed.

And if the container main body 2 is formed with a synthetic resin, the container main body 2 will have water resistance. Furthermore, even if water or the like has accumulated at the bottom of the storage container 1 by using the container body 2 formed into a box shape by heat-sealing a flexible material made of synthetic resin having water resistance, etc. It is also possible to prevent it from leaking outside.
In addition, when the use of the storage container 1 does not require water resistance and it is not necessary to consider water leakage, the flexible material forming the container body 2 includes a material other than a synthetic resin film material or sheet material, For example, woven fabric, non-woven fabric, knitted fabric, paper, etc. can be used. Furthermore, in such a case, even if the foam has a cellular structure communicating with the surface such as polyurethane foam, it can be used as long as it is a material that can be molded into a flexible sheet. The container body 2 can also be formed.

Moreover, as a flexible material which forms the container main body 2, the bubble sheet | seat made from a synthetic resin in which many independent bubble chambers as shown in FIG. 2 were formed can also be used, for example.
FIG. 2 is an explanatory view of a main part of an example of a synthetic resin air bubble sheet.
This bubble sheet is formed by laminating a back film 233 so as to seal the opening side of the protrusion 231 on the cap film 232 on which a large number of protrusions 231 bulging in a hollow shape are formed. A sealed bubble chamber is formed. At the same time, a liner film 234 is laminated on the top side of the protrusion 231 so that the uneven shape due to the protrusion 231 does not appear on the surface.
Forming the container body 2 using such a synthetic resin-made air bubble sheet is preferable because it is lightweight but provides cushioning (impact resistance) and heat insulation effects. This is remarkable when the container body 2 has a double structure in which the outer layer member 23 and the inner layer member 24 are overlapped as in the present embodiment.
Although not particularly illustrated, when such a bubble sheet is used as a flexible material for forming the container body 2, the liner film 234 laminated on the top side of the protrusion 231 of the bubble sheet shown in FIG. 2 is omitted. It is good also as a structure.

The container body 2 is provided with a loading portion 4 for detachably attaching the reinforcing member 3 (see FIG. 1). The insertion portion 4 is provided at corners located at the four corners of the side wall portion 21, and specifically, a space in which the reinforcing member 3 can be inserted and removed between the outer layer member 23 and the inner layer member 24 that are overlapped. Are formed along the vertical direction.
By providing such a loading portion 4, the reinforcing member 3 can be easily attached and detached. Further, by forming a gap between the outer layer member 23 and the inner layer member 24 to form the charging portion 4, the charging portion 4 can be provided integrally with the container body 2, and the structure can be simplified. It becomes possible.

  Here, when the container body 2 has a double structure in which the outer layer member 23 and the inner layer member 24 are overlapped, the outer layer member 23 and the inner layer member 24 are thermally fused so as not to be easily separated during use. It can be joined by appropriate means such as wearing, adhesive, adhesive tape, hook-and-loop fastener and hook. Moreover, when providing the insertion part 4 as mentioned above, it is sufficient that at least the insertion part 4 has a double structure. For other parts, the outer layer member 23 or the inner layer member is necessary. One of 24 may be omitted.

Next, the reinforcing member 3 that is detachably attached to the container body 2 will be described.
3A and 3B are explanatory views showing an example of the reinforcing member 3. FIG. 3A is a plan view, and FIG. 3B is a cross-sectional view taken along the line BB in FIG.
The reinforcing member 3 can be formed, for example, by making a bag of a film material in a rod shape so that the periphery is fused while leaving the opening 32. And the air valve 31 which is a cylindrical air flow path which connects the inside and outside of the reinforcement member 3 is attached to the opening part 32, and the site | part 311 located inside the reinforcement member 3 of the air valve 31 is reinforced. The inner surface of the member 3 is fixed.
In addition, as a film material which forms the reinforcement member 3, the film material which consists of the resin material similar to having illustrated as a flexible material can be used.

When such a reinforcing member 3 is inflated by press-fitting air into the reinforcing member 3 through the air valve 31, the internal air pressure acts in the direction of the arrow P as shown in FIG. The path is crushed to keep the air valve 31 closed.
Further, the opening 32 is fused in the direction of the arrow R shown in FIG. 3B to close the air flow path, so that the pressed-in air can be sealed so as not to leak to the outside of the reinforcing member 3. .
In fusing the opening 32, unnecessary portions on the edge side can be cut and removed at the same time.

In this embodiment, as the fluid to be press-fitted and sealed into the reinforcing member 3, the weight is reduced by using easily available air. For example, when a predetermined weight feeling is required, a liquid such as water is used. It is good also as a structure which press-fits.
The reinforcing member 3 is usually attached to the container main body 2 in a state where the fluid is press-fitted and sealed. For example, after the article is placed in the container main body 2, the fluid is press-fitted and sealed in a state of being attached to the container main body 2. You may do it.

  Further, as shown in FIG. 1, the reinforcing member 3 in the present embodiment is formed so as to have a substantially cylindrical rod shape. And such a reinforcement member 3 is attached to the insertion part 4 formed in each of the corner | angular part located in the four corners of the side wall part 21. As shown in FIG. Thereby, the shape retainability of the storage container 1 can be improved effectively.

Since the container body 2 is formed of a flexible material, the storage container 1 of the present embodiment can be folded or assembled as follows.
4 is a perspective view showing a state where the container main body 2 and the reinforcing member 3 are separated from each other, and FIG. 5 is a perspective view showing a state where the container main body 2 is folded.
When the storage container 1 is not used, each reinforcing member 3 inserted into each charging portion 4 of the container body 2 is taken out, and the container body 2 and the reinforcing member 3 are separated (see FIG. 4). For example, as shown in FIG. 5, the container 1 can be made compact by folding the container body 2. In folding the container body 2, the folding method is not limited to the example shown in FIG. 5, and the container body 2 may be easily folded according to the form of the container body 2. Moreover, in order to make the container main body 2 easy to fold, the container main body 2 can also be folded.
Thus, since the storage container 1 of this embodiment is foldable, when not in use, it can be prevented from being bulky by being folded, and can be easily carried.

  Further, when the storage container 1 is used, an operation reverse to the above, that is, the folded container body 2 is restored to a box shape, and each of the charging sections 4 provided at the four corners of the container body 2 is restored. It can assemble by inserting each reinforcement member 3 (refer FIG. 1). Accordingly, the storage container 1 is reinforced by the reinforcing member 3 and has excellent shape retention.

In the present embodiment, the storage container 1 may have a columnar shape in which the side wall 21 is cylindrical as shown in FIG. 6, for example, instead of the storage container 1 having a cubic shape. In this example, the container main body 2 has a circular bottom portion 22 and a side wall portion 21 that rises in a cylindrical shape from the periphery of the bottom portion 22, and a plurality of (in the example shown in FIG. 6) that are spaced apart from each other in the circumferential direction. Four) charging portions 4 are provided along the vertical direction. And each reinforcement member 3 is inserted in each of each insertion part 4, and the storage container 1 is formed.
In addition, the shape of the side wall part 21 is not limited to this, For example, it is good also as a side wall part of various shapes, such as an elliptic cylinder shape and a polygonal cylinder shape. Furthermore, although the bottom part 22 is normally made into the flat plate shape of the shape corresponding to the cross-sectional shape of the side wall part 21, it is not limited to this, For example, it is good also as a curved shape.

  Furthermore, the shape of the storage container 1 may be a shape corresponding to the shape of the article to be stored. Although not particularly illustrated, for example, the side wall portion 21 may be formed in a conical shape.

[Second Embodiment]
Next, the storage container according to the second embodiment of the present invention will be described.
In the first embodiment, the reinforcing member 3 that is detachably attached to the container body 2 is formed by press-fitting and sealing a fluid into a stick-formed film material. The storage container 1 is different from the first embodiment in that a reinforcing member 30 as shown in FIGS. 7 to 9 is used. For this reason, description is abbreviate | omitted about the part which is common in 1st embodiment, and the reinforcement member 30 used by this embodiment is demonstrated below.

  FIG. 7 is a perspective view of the reinforcing member 30 used in the present embodiment, and FIG. 8 is a development view of the reinforcing member 30 used in the present embodiment. The reinforcing member 30 is the same as that used for the container body 2. Using a flexible material, a cylindrical portion 303 formed in a square tube shape having a square cross section is provided. Such a reinforcing member 30 is formed by, for example, processing a predetermined portion of a flat plate-like flexible material so that it can be bent, and cutting out the predetermined portion by heat so as to have a shape as shown in FIG. It can be formed by bonding with a seal (heat fusion) or the like.

  The cylindrical part 303 is formed on the surface part of the cylindrical part 303 so as to be orthogonal to the corner folding line L1 and four corner folding lines L1 that can be bent at the four corners. Along the diagonal line of the square part 331, the foldable surface part folding line L2 that forms four square parts 331 arranged in the circumferential direction of the cylindrical part 303 between the seal line L2 or the edge line L4 of the cylindrical part 303. And a foldable diagonal fold line L3. The diagonal bending line L3 only needs to be formed along one of the two diagonal lines of the square portion 331, but the four lines formed in the four square portions 331 arranged in the circumferential direction of the cylindrical portion 303 are each. As shown in FIG. 2, the diagonal folding lines L3 of the books must face the same direction in the unfolded state and be parallel to each other.

When the seal lines L1 to L3 are formed as described above, the four square portions 331 arranged in the circumferential direction of the cylindrical portion 303 are, as shown in FIG. 9, the corner bending line L1 and the surface portion forming the square portion 331. The folding line L2 is a mountain fold, and the diagonal folding line L3 in the square part 31 is a valley fold, thereby forming a foldable part 332 that can be folded toward the hollow part of the cylindrical part 303. The foldable portion 332 can be easily folded by holding both ends of the cylindrical portion 3 with both hands and twisting it 90 degrees in a predetermined direction. When the foldable portion 332 is folded, each square portion 331 is folded in half with the diagonal fold line L3 as a valley fold, forming a right isosceles triangle. Then, the four right-angled isosceles triangles in which each square portion 331 is folded are sequentially overlapped with adjacent right-angled isosceles triangles, whereby the foldable portion 332 is folded in a planar shape.
According to such a reinforcing member 30, by folding the foldable portion 32, the length can be appropriately adjusted according to the size of the container body 2, which is common to the container bodies 2 having different sizes. Can be used.
In addition, in the example shown in FIGS. 7-9, although the foldable part 32 is continuously formed in the length direction of the cylinder part 3, it is not limited to this. It is also possible to increase the degree of freedom in adjusting the length of the reinforcing member 30 by appropriately changing the position where the foldable portions 32 are formed and the number thereof.

  While the present invention has been described with reference to the preferred embodiment, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. .

For example, in the above-described embodiment, the reinforcing member 3 is provided along the vertical direction, but is not limited thereto. Depending on the shape of the container and the shape of the article to be stored, for example, the reinforcing member 3 may be disposed in the horizontal direction, may be disposed obliquely, or may be disposed in a lattice shape. .
Further, in the above-described embodiment, the reinforcing member 3 is attached to the corner portion of the side wall portion 21 having a rectangular tube shape, but may be appropriately attached to other than the corner portion of the side wall portion 21.
Moreover, the form of the form of the reinforcing member 3 can also be appropriately changed as necessary, for example, in the form of a plate.

  Further, in the above-described embodiment, the reinforcing member is provided in the insertion portion 4 provided by forming, along the vertical direction, a space in which the reinforcing member 3 can be inserted and removed between the overlapped outer layer member 23 and inner layer member 24. However, the attachment means of the reinforcing member 3 is not limited to this. If the reinforcing member 3 can be attached so as to ensure the shape retaining property of the storage container 1, it may be detachably attached by, for example, a hook-and-loop fastener.

  In the above-described embodiment, an example in which the shape of the container main body 2 is a box shape having an upper surface opened is shown, but an upper lid may be provided on the upper surface of the container main body 2. Moreover, you may provide a handle in the side wall part 21 for the ease of handling at the time of conveyance of the storage container 1. FIG.

  The present invention can be widely used as a storage means for various articles.
