Description

[Detailed explanation of the invention] Purpose of the invention (industrial application field) This invention is used by storing vegetables inside with only the upper end exposed above the ground and most of the rest buried underground. This article concerns an underground vegetable storage box.

(Prior art) No prior art is found in this invention.

(Problem to be solved by this invention) The problem to be solved by this invention is to make it possible to preserve stored vegetables cleanly and freshly for a long period of time in a state close to their natural state.

Structure of the invention (means for solving the problems) In order to solve the above problems, this invention has an open top surface, a flange portion with a first vent hole formed through the upper edge, and a flange portion on the bottom wall. A box body with an opening formed therein, a breathable mat laid on the inner bottom surface of the box body so as to cover the opening, and a top opening of the box body that covers the opening in an openable/closable manner, and has the flange on the outer edge. a lid forming a hanging part facing the part;
The box body is sandwiched between the lid and the box body, and includes a heat insulating plate having a second vent hole corresponding to the first vent hole formed in the peripheral edge thereof.

(Function) With the solution described above, the stored vegetables can be stored for a long period of time at an optimal storage temperature without causing a decrease in freshness.

(Example) An example embodying this invention will be described below with reference to Figures 1 and 2. The underground vegetable storage box of this example has a square box shape with an open top. A box body 1 made of synthetic resin, a mat 7 that is molded separately from the box body 1 and laid on the inner bottom surface of the box body 1, and a synthetic resin that covers the top opening 1a of the box body 1 in an openable and closable manner. It is composed of a lid 2 made of resin and a heat insulating plate 4 made of, for example, foamed urethane mat stuck to the inner surface of the lid 2.

Legs 5 are formed at the bottom of the box body 1. An opening 6 is formed in the center of the bottom wall of the box body 1, and when the box body 1 is buried underground, the vegetable V
The moisture released from the box is allowed to escape into the ground, and an appropriate amount of moisture can be introduced into the box body 1 from the ground. A mat 7 made of breathable synthetic resin is laid on the inner bottom surface of the box body 1 to cover the opening 6 and prevent insects, moles, etc. from entering.

On the other hand, a flange portion 1 is attached to the upper edge of the box body 1.
b, and a hanging portion 1c extending downward from the flange portion 1b. Flange part 1 on each side
A cutout 8 serving as a first ventilation hole is transparently provided in the center of b.

Further, a pair of handles 9 are integrally formed on the upper surface of the lid 2, and a hanging part 2a facing the hanging part 1c is integrally formed on the outer edge over the entire circumference. A notch groove 3 having a planar U-shape as a second ventilation hole is formed in the peripheral edge of the heat insulating plate 4,
When the lid 2 is closed, the outer edge of the heat insulating plate 4 is held between the flange portion 1b of the box body 1 and the lid 2, and each notch groove 3 corresponds to the notch 8. The groove 3 constitutes a ventilation path T.

By the way, when using the underground vegetable storage box of this embodiment configured as described above, as shown in FIG. is buried in the ground, vegetables V are stored therein, and the top open part 1a is closed with a lid 2. In this way, the temperature inside the box body 1 will be almost equal to the underground temperature due to the heat insulation effect of the heat insulating plate 4 of the lid 2 and the heat conduction through the side walls inside the box body 1, so that it will be lower than the outside temperature in winter. The high temperature also prevents frost damage, and in the summer, the temperature is lower than the outside temperature.
It is possible to prevent spoilage and store vegetables V at an optimal storage temperature for a long period of time without causing a decrease in freshness in any season.

Further, even when the box body 1 is closed with the lid 2, the ventilation passage T is formed by the notch groove 3 formed in the heat insulating plate 4 and the flange portion 1b of the box body 1 matching with the notch 8. Therefore, air is prevented from stagnation within the box body 1, so there is no inconvenience that the vegetables V will ferment or rot. Furthermore, to prevent the outside air from drying out in the winter, it is possible to store the mat 7 by laying straw or the like on top of it, and by covering it with straw (not shown), it is possible to keep the room warm and at the same time keep the humidity constant. can.

Therefore, in much the same way as the preservation method of directly burying vegetables in the ground, which has been practiced for a long time in areas with snowfall, vegetables V can be stored fresh in a state close to nature. It can be stored cleanly without getting dirty. In addition, since the ventilation path T is covered by the lid 2 on which the hanging part 2a is formed, problems such as mud from the ground surface entering the inside of the box body 1 or snow entering during snowfall are avoided. do not have.

In addition, since the box body 1 is formed with a hanging portion 1c, when the lid 2 is sealed, the hanging portion 2a of the lid 2 and the hanging portion 1c of the box body 1 are joined, and the lid 2 becomes the box body. 1 to prevent it from falling off.

It should be noted that this invention is not limited to the above-mentioned embodiments, and the shapes and configurations of the various parts can be changed and embodied as desired without departing from the spirit of this invention.

Effects of the invention As detailed above, this invention is achieved by providing a first vent in the flange of the box body and forming a second vent corresponding to the first vent in the periphery of the heat insulating plate. The air inside the box body can be ventilated, and the temperature inside the box body can be made almost equal to the underground temperature due to the heat conduction through the side walls inside the box body as well as the insulation effect of the heat insulating board. By forming an opening in the bottom wall of the box body, it is possible to allow moisture released from vegetables to escape into the ground when buried underground, and also to introduce an appropriate amount of moisture from underground into the box body. Since it is covered with breathable pine, it can prevent the intrusion of insects, moles, etc. In addition, the ventilation path consisting of the first ventilation hole and the second ventilation hole extends through the hanging part. Since it is covered with a lid, there is no chance of dirt from the ground entering the inside of the box, or snow from entering when it snows, so the stored vegetables can be kept clean and in a state close to their natural state. It has the excellent effect of being able to be stored for a long time without losing its freshness.
