DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a concave portion formed on a side surface so that the container can be folded, and which can be folded vertically.

[0002]

2. Description of the Related Art In a conventional container, since the entire container is kept in a fixed state, it is difficult to bring the entire container into a folded state when no contents are stored in the container. In addition, the container to be folded was also folded in one direction on the outside. For this reason, when transporting and storing the container, the container is handled in a bulky state in the same state as when there is a content, so that there is a problem that the working efficiency and the space efficiency are very poor.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a foldable container having high transportation efficiency and storage efficiency, in which a container in which no contents are stored can be folded and deformed into a compact shape. The purpose is to provide.

[0004]

According to the present invention, a plurality of Y-shaped recesses are formed on opposing first side surfaces from a middle portion of each side surface to an upper end portion and a lower end portion. Two concave portions connecting the Y-shaped end portions in an oblique direction are formed, and the second side surface is formed with a horizontal concave portion through the Y-shaped crossing portion and the end portion, and more preferably. The present invention relates to a container in which a concave portion is formed horizontally on an upper edge and / or a lower edge of the first side surface and the second side surface.

[0005]

The container according to the present invention applies a vertical force when no contents are stored in the container.
Utilizing a concave portion provided on the side surface of the container, the side surface is folded so that the upper surface and the lower surface can be brought close to each other, so that the side surface is folded.

The concave portion is for folding the upper surface and the lower surface close to each other, and may be provided so as to be foldable, but is preferably provided as shown in FIG. The concave portion may be formed so as to be easily folded, and is preferably formed inward, but may be formed outward in some cases.

[0007] The shape of the container is not particularly limited, but when the space is made as small as possible when folded,
The shape of the upper surface and the lower surface is preferably flat. Also,
When two or more containers are stacked, the shape may be such that the concave portion on the upper surface and the convex portion on the lower surface and the convex portion on the upper surface and the concave portion on the lower surface overlap.

The shape of the side surface of the container is not particularly limited. However, in consideration of the storage and strength of the container and to make it easier to fold, the opposing first side surface is bulged outward and the other opposing side surface is expanded. It is particularly preferred that the two sides are recessed inward. Also, the largest part of each bulge or dent is preferably in a horizontal concave part provided in the intermediate part, and it is particularly preferable that the bulge or dent is formed in the intermediate part. Further, the container may have a reinforced structure.

As the material of the container, a commonly used material is used, and as the hard material, a polyolefin or a laminate in consideration of gas barrier properties including polyolefin is preferable, and polyethylene, polyethylene and ethylene vinyl are preferred. Alcohol laminates and the like are particularly preferred.

The recess may be formed so that the container can be folded, but may be formed toward the inside of the container or may be formed toward the outside. In addition, when the container is made thick, the concave portion can be formed by making the wall of the container thin.

The container is usually preferably provided with a port to which a cap for filling the contents is attached, but may be a bucket having an opening at the entire upper part.
If a cap is attached, not only to prevent leakage of the contents, but also to prevent air from entering the container after folding when the contents are not stored, and to provide a tightly closed container to maintain the folded state Is preferred.

Since the container may return to its original shape after being folded, by closing the mouth with the cap after folding, it is possible to suppress air from flowing into the container.

In order to transport and store the container, it is preferable that the container be folded and the folded container be kept in that state. It is preferable to carry out. Further, the shape may be maintained by placing the shape in a bag or a container. The bag may be adapted to the folded shape. By doing so, the container can be more completely held in the folded state.

In order to fold the container, if the container is sealed with a cap so that air can be exhausted, the cap is removed and the upper surface is folded down by pressing the upper surface downward so that the side surface is folded by the concave portion. This is done by integrating them. It is also possible to stack a plurality of containers capable of discharging air and to bleed air at a time. In this case, a device capable of storing a plurality of containers in a stacked manner may be used, or the folded containers may be held as they are.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. EXAMPLE A container 1 of FIG. 1 has a handle 9 for holding the container 1 on an upper surface 5.
And a port 7 for filling the contents,
Forms a flat surface. The mouth 7 is formed so as to prevent the contents from leaking after the contents are filled or folded, and to attach a cap 8 for maintaining the shape. Also, a pair of first
The side surface 3 bulges outward, and the other pair of second side surfaces 4 have a concave shape inward. Two substantially Y-shaped recesses 2 are provided on a pair of opposing first side surfaces 3 with a diagonal line from upper right to lower left (a corresponding surface is a diagonal line from upper left to lower right). One substantially Y-shaped concave portion 2 provided above the diagonal line is provided from the upper right to the lower left of the first side surface 3 (the corresponding surface is from the upper left to the lower right), and passes through the substantially Y-shaped intersection 10. The parallel concave portion 2 is also provided on the side surface of the second side surface 4. The other substantially Y-shaped concave portion 2 provided below the diagonal is provided from the upper right to the lower left of the first side surface 3 (the corresponding surface is from the upper left to the lower right), and is an end connected to the substantially Y-shaped second side surface. The recesses are also parallel to the second side surface.
Is provided. Further, the second side surface 4 is provided with horizontal concave portions 11 and 12 at the upper edge or the lower edge. The container 1 is detached by removing the cap 8, holding the handle 9, and pushing down to discharge the air in the container 1 and simultaneously folding the container 1 to form the folded container shown in FIG. 4.

[0016]

According to the present invention, since the container is formed so as to be foldable, the space can be saved, and the container can be easily stored and transported. In addition, since costs for storage and transportation can be reduced, costs can be reduced. In the case of a container having a mouth with a cap, the folded state can be maintained without returning to the original state by fitting the cap into the mouth by improving the airtightness. Further, when the container is discarded, the container can be made compact, so that the amount of waste can be greatly reduced.
