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.

Traditionally, 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 were packed with moisture. It is unhygienic and labor-intensive to collect, making inventory management difficult.

In addition, the stored long potatoes contain about 60% water and cause perspiration, so if they are stuffed inside sawdust or rice hulls, they will not be able to produce sufficient perspiration, and the packaging will not be suitable for long potatoes, resulting in discoloration. They tend to change or suffer other quality deterioration, and it is very time-consuming to insert and remove long potatoes from sawdust, rice hulls, etc.

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 sheet, with a plurality of long groove-shaped recesses for storing long potatoes on the top side. The recesses are arranged in parallel, and the bottom surface of the recesses is characterized by having a large number of inwardly bulging protrusions formed in a staggered manner.

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

1 shows the entire container for long potatoes, which is made of a thermoplastic resin sheet, and a plurality of long groove-shaped recesses 2 for storing long potatoes are arranged in parallel on the upper side with a flat part 3 in between. The recess 2 is formed by a downward bulge of the sheet.

Further, on the bottom surface of the four parts 2, a large number of protrusions 20 that bulge inward in small circles or other shapes are formed in a staggered manner, and the protrusions 2
A space 4 is formed between 0.degree.

Therefore, when long potatoes A are stored individually or in plural pieces in the recess 2, the long potatoes A will rest on a large number of protrusions 20,
The large number of protrusions 20 can support the long potato A with good cushioning properties.

In addition, the space 4 formed between the protrusions 20 and 20 of the long potato A enhances the buffering effect, makes it easy for moisture and dirt attached to the long potato A to fall off, and also helps improve air permeability. It is configured.

Furthermore, as the long groove-shaped recess 2 for storing long potatoes, in addition to the implementation in which a part of the long potatoes A comes out on the top surface of the container, a four part 2 is formed in which the entire long potato A is accommodated within the four part 2, and the top surface of the container is Covering the lid 5 made of flexible foam sheets 1 to 1 prevents dust from entering from the outside and provides excellent cushioning properties (see FIG. 3).

As the thermoplastic resin sheet forming the above-mentioned container 1,
Non-foamed sheets made of resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. or foamed sheets obtained by foaming these resins are used, and particularly preferred are foamed sheets with excellent cushioning effects, self-supporting properties, and rigidity. Polystyrene I. is used.

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 flat portion 3 formed between each concave portion of the lower container 1 and around the container is used for stacking the upper container 1. The upper and lower containers 1, 1 are stacked in a staggered manner so that they can support the bottom, but the widths of the flat parts 31 and 32 formed on the left and right sides of the containers are changed to form a constant shape. If the upper and lower containers 1, 1 are rotated 180 degrees and stacked alternately on the left and right, the left and right ends of the upper and lower containers 1, 1 will be aligned, which can be carried out suitably for storage in a cardboard box etc. and for display at the time of sale. (See Figure 4).

Furthermore, if a protrusion 33 is formed on the upper surface of the flat portion 3 to be able to fit into the recessed portion formed on the lower surface of the protrusions 20, 20, positioning during stacking can be easily performed and misalignment that may occur during transportation etc. can be prevented. be able to.

According to the container for long potatoes of this invention constructed as described above, individual or multiple long potatoes can be stably stored in the recess for storing long potatoes, and the bottom of the four parts has bulges in small circular or other shapes. Since the large number of protrusions 20 are formed in a staggered manner, the protrusions 20 supporting the long potatoes easily escape into the 4 spaces between the protrusions 20 as the long potatoes are stored, and the long potatoes are This allows for a reasonable support, which has a good buffering effect and can absorb the vibrations and shocks of the container, preventing breakage, damage, and quality deterioration of the long potatoes due to external forces.
Moisture in the long potatoes, attached dirt, etc. can easily fall into the space 4 between the protrusions 20 and 20 and be accommodated therein, and the space 4 also has the advantage of improving the ventilation of the lower part of the long potato storage.

Therefore, there is no need for conventional cushioning materials such as sawdust,
The perspiration effect of long potatoes is not inhibited, and during transportation, it is sufficient to simply stack the containers of the present invention and store them in a cardboard box, etc., and when selling, the containers of the present invention can be displayed for good appearance. In addition, when storing containers without storing long potatoes, by placing the recesses of many containers one on top of the other, it is possible to keep them all together in a compact container because they are made of sheet material. Since a thermoplastic resin sheet is used as the material, it is easy to mold, easy to manufacture, and has low production costs.In particular, if foam sheets 1 to 1 are used, the cushioning properties will be even better.It is also extremely lightweight. It becomes a container.

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. be.
