Description

[Detailed description of the invention] This invention relates to a container for long potatoes, and aims to provide a container that can store long potatoes with good cushioning properties, is easy to handle, and is suitable for transportation and storage.

Conventionally, the packaging for transporting and storing long potatoes (Dioscorea japonica) was to store large quantities of long potatoes together with sawdust and rice hulls in water-resistant cardboard boxes, but sawdust and rice hulls did not contain moisture. It is unhygienic, requires labor to collect, and inventory management is difficult.

In addition, since the stored long potatoes contain about 60% water and produce a sweating effect, storing them in the bag described above and stuffing them inside sawdust or rice hulls does not allow for sufficient sweating, which is suitable for long potatoes. It is no longer in a packaged state,
It is easy to cause color change or other quality deterioration,
Inserting and removing sawdust and potatoes into and out of the rice husk tube was very time-consuming.

Packaging using air cap sheets has also been attempted, but it has drawbacks such as difficulty in generating sufficient perspiration and the long potatoes often breaking due to impact from outside the cardboard.

Therefore, in this invention, we provide a container that can eliminate the above-mentioned drawbacks, and its structure is entirely made of a thermoplastic resin foam sheet, and the top side has a plurality of long grooves for storing long potatoes. The recesses are arranged in parallel, and the recesses form an inwardly sloping part that is narrower than the opening, and a bottom part that protrudes further downward than the long potato storage part is formed at the lower end of the recess, and the upper surface side A feature is that the flat portions formed on the left and right peripheries in the longitudinal direction are formed with different widths.

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

1 shows the whole container for long potatoes, which is made of a thermoplastic resin foam sheet, and on the top side, a plurality of long groove-shaped recesses 2 for storing long potatoes are lined up with a flat part 3 in between. The recess 2 is formed by a downward bulge of the sheet to form an inwardly sloping portion that is narrower than the opening.

A bottom portion 21 is formed at the lower end of the long groove-shaped recess, and protrudes further downward than the storing portion of the long potato A. The shapes of the recess portion 2 and the protruding bottom portion 21 are, for example, as shown in FIG. The center of the V-shaped recess 2 shown in the figure is the bottom 21.
As shown in Fig. 3, only the lower end of the recess 2 is sloped in a V-shape so that the bottom part 21 protrudes downward. This is an embodiment in which a groove in the direction is provided to form a bottom portion 21 that projects downward.

In addition, the protruding bottom part can be implemented in various shapes, such as a case in which it is partially protruded (not shown) rather than the entire part in the elongated direction.

31 and 32 are flat portions 3 formed on the left and right peripheries of the upper surface of the container in the longitudinal direction, and are formed with different left and right widths.

As the thermoplastic resin foam sheet forming the container 1, a foam sheet obtained by foaming a resin such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. is used,
Particularly preferably, a polystyrene sheet is used, which has excellent cushioning effect, self-supporting properties, and rigidity.

The container 1 for long potatoes according to this invention stores long potatoes A individually or in plural pieces in the long groove-shaped recess 2 for storing long potatoes. The bottom part 21 can be used as a kind of supporting leg, and a space 4 is formed between the bottom part 21 and the long potato A having a substantially round cross section, which increases the buffering effect and removes moisture and dirt attached to the long potato. can easily fall off and can further improve breathability.

In addition, although the long potato container 1 may be used alone,
In most cases, it is preferable to stack a plurality of containers 1, and in this case, the upper container 1 can The upper and lower containers 1 are arranged so that the protruding bottoms 21 of the
, 1 are stacked by shifting them, but since the width of the flat parts 31 and 32 formed on the left and right peripheries of the containers is changed and formed into a constant shape, the upper and lower containers 1, 1 are stacked at 180 degrees.
If they are rotated and stacked alternately on the left and right, the left and right ends of the upper and lower containers 1, 1 will be aligned, and together with the concave shape, it will be possible to take up a lot of space for storing long potatoes, which can be stored in cardboard boxes etc. and displayed at the time of sale. It becomes more suitable.

Furthermore, by forming a groove 33 on the upper surface of the flat portion 3 that can fit into the lower surface of the protruding bottom portion 21, positioning during stacking can be easily performed and misalignment that may occur during transportation etc. can be prevented. (See Figure 6).

Furthermore, as a modification example, the implementation shown in FIG. The recesses 2 are arranged in an elongated triangular shape, and are suitable for individually storing the tapered long potatoes A, and the elongated triangles of adjacent recesses 2 are arranged in reverse directions. Therefore, space can be used more efficiently compared to a case where all the elongated triangles of the recesses 2 are in the same direction, and the container 1
can be placed horizontally without tilting, and container 1 can be placed horizontally without tilting.
When stacking containers 1 on top and bottom, if the corresponding elongated triangular recesses 2 of the upper and lower containers 1 are stacked so that they are reversed, the protruding portion 21 is moved downwards into the flat portion of the container 1 on the bottom. 3, and can be suitably implemented.

According to the container for long potatoes of this invention constructed as described above, since the concave part has an inwardly sloping part that is narrower than the opening, individual or multiple long potatoes can be stored in the concave part for storing long potatoes. It can be easily and stably stored without damaging the
Moreover, the protruding bottom part, which is located at the lower end of the recess and is formed further down than the storage area of the long potatoes, can buffer the impact and vibration of the container, and prevent the long potatoes from being broken, damaged, and quality deteriorated due to external force. The water content, adhering dirt, etc. of the long potatoes can easily fall off and be stored, and the protruding bottom space has the advantage of improving ventilation at the bottom of the long potato storage.

Furthermore, since the container is made of a foamed sheet, the above-mentioned cushioning properties are even more excellent.

Therefore, conventional cushioning materials such as sawdust are no longer necessary.
The perspiration effect of long potatoes is no longer inhibited, and during transportation, the containers of this invention can be stacked alternately on the left and right and stored in a cardboard case, etc., allowing for storage with sufficient storage space for long potatoes. It can be used neatly even when displayed in the original container, and if the container is to be stored without storing long potatoes, the recesses of many containers can be stacked one on top of the other, making it very compact since it is made of sheet material. In addition, since thermoplastic resin foam sheets are used as the container material, they are extremely lightweight, and are easy to manufacture and have low production costs, especially when using expanded polystyrene sheets. can further promote weight reduction.

As mentioned above, this invention has very high practical effects, such as being able to transport and store long potatoes without deteriorating their quality, and providing containers for long potatoes that are easy to handle and manufacture. .
