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, requires labor to collect, and inventory management is 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. Color change or other quality deterioration is likely to occur, and insertion and removal of long potatoes into sawdust, rice hulls, etc. is very time-consuming.

Packaging using air cap sheets has also been attempted, but it has drawbacks such as difficulty in producing sufficient perspiration and the fact that the cardboard is often damaged due to impact from outside.

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. They are arranged side by side, and the bottom surface of the recess is characterized by forming bellows-shaped unevenness along the long groove-shaped recess and in the width direction.

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 recess 2, a bellows-shaped unevenness 20 is formed along the long groove-shaped recess and in the width direction, so that when the long potatoes A are stored individually or in plural pieces in the recess 2, the long potatoes A are It will rest on the bellows-shaped unevenness 2, and even if the long potato A is large, it will be possible to exhibit dimensional flexibility by expanding the unevenness 20. Moreover, by forming the unevenness 20, the bottom back side The resulting protrusion 21 can be used as a kind of elastic supporting leg, which improves the cushioning properties. In addition, the space 4 formed between the long potato A and the concave part of the unevenness 20 has a cushioning effect. As well as increasing the moisture content and dirt attached to the potato A, it becomes easier to remove it.
It is also designed to help improve breathability.

In addition to the illustrated example in which the bellows-shaped unevenness 20 has three protrusions, it is also possible to have two protrusions or four or more protrusions. Accordingly, the number of protrusions 21 on the back surface of the container also changes.

Furthermore, as the long groove-shaped recess 2 for storing the long potatoes 5, in addition to the implementation in which a part of the long potatoes A comes out on the top surface of the container, the recess 2 is formed such that the entire long potatoes A are accommodated in the recess 2, and the container Covering the top surface with a lid 5 made of a flexible foam sheet or the like prevents dust from entering from the outside and provides excellent cushioning performance (see FIG. 4).

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 polystyrene sheets with excellent cushioning effects, self-supporting properties, and rigidity. 1. 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 protrusion 21 toward the outer surface of the bottom. The upper and lower containers 1, 1 are formed into a certain shape, and the upper and lower containers 1, 1 are
If they are rotated and stacked alternately on the left and right sides, the left and right ends of the upper and lower containers 1, 1 will be aligned, making it suitable for storage in a cardboard box or the like and for display at the time of sale (see FIG. 5).

Further, a groove (not shown) that can fit into the lower surface of the protruding part 21 is formed on the upper surface of the flat part 3, or a protrusion 33 that can fit into the gap 22 formed between the plurality of protruding parts 21 is formed. If formed, positioning during stacking becomes easy and misalignment that occurs during transportation can be prevented.

According to the container for long potatoes of this invention constructed as described above, individual or plural long potatoes can be stably stored in the long groove-shaped recess for storing long potatoes, and at this time, bellows-shaped unevenness is formed on the bottom of the recess. As a result, the vibrations and shocks of the container can be well absorbed by the unevenness, preventing breakage, damage, and quality deterioration of the long potatoes due to external forces.In addition, moisture in the long potatoes and attached dirt can be absorbed into the spaces between the unevenness. The space has the advantage of allowing good ventilation at the bottom of the long potato storage area.

Furthermore, by forming bellows-shaped unevenness on the bottom along the long groove-shaped recess and in the width direction, the bottom part can be expanded in the width direction, and a part of the recess 2 can be expanded according to the shape of the long potato A. Since it can be deformed, it can also store somewhat larger long potatoes, making it very suitable as a container for long potatoes 1, which originally have many variations in shape and size.

Therefore, there is no need for conventional cushioning materials such as sawdust,
It no longer inhibits the perspiration effect of long-term sweet potatoes, and during transportation, it is sufficient to stack them in the containers of the present invention and store them in a cardboard box, etc., and when selling them, they can be displayed in the containers of the present invention for a nice appearance. In addition, when storing containers without storing the long sweet potatoes 1, by placing the recesses of many containers one on top of the other, it is possible to store them very compactly because they are made of sheet material, and the containers can be stored very compactly. Because thermoplastic resin sheets are used as the material,
It is easy to mold, easy to manufacture, and has a low production cost. Especially, if a foam sheet is used, the container has excellent cushioning properties and is extremely lightweight.

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.
