Description

The present invention relates to storage.

Conventionally, there is a container described in Patent Document 1 below. The container described in Patent Literature 1 includes electrodes arranged therein and a power supply that applies a voltage to the electrodes. The container is formed in a rectangular box shape. The electrodes are fixed to the inner surface of the bottom wall or the inner surface of the upper wall of the container, and form an electrostatic field atmosphere inside the container based on the voltage applied from the power source.

JP-A-2001-204428

Since the electrodes have a relatively large weight, when a plurality of electrodes are to be fixed to the inner surface of the upper wall of the container, reinforcing members are often provided on the inner surface of the upper wall of the container. For example, at the time of manufacture of the container, special processing is applied to fix the reinforcing member to the inner surface of the upper wall portion, and then the plurality of electrodes are installed so as to be suspended from the reinforcing member. In this way, if an attempt is made to arrange the electrodes in the container, complicated processing is required for the container. Since this is a factor that hinders the popularization of storage boxes in which electrodes are installed, it is desired to improve it.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a container in which an electric field forming member can be arranged more easily.

A container for solving the above problem includes a container main body having a container therein, and an electric field forming member for forming an electric field inside the container. A mounting portion on which the electric field forming member is mounted is provided on the side wall portion of the container body.
According to this configuration, the placement of the electric field forming member in the storage chamber is completed simply by placing the electric field forming member on the mounting portion provided in the storage body. Therefore, since it is not necessary to apply complicated processing to the container main body in order to arrange the electric field forming member in the storage chamber, the electric field forming member can be arranged more easily.

In the container described above, it is preferable that a plurality of electric field forming members are placed on the placing portion.
According to this configuration, a wider electric field can be formed by combining a plurality of electric field forming members. In addition, since the size of each electric field forming member can be reduced, installation of the electric field forming member in the container is facilitated.

In the storage container described above, when the two side wall portions that are arranged to face each other in the storage main body are the first side wall portion and the second side wall portion, the first side wall portion is provided as the mounting portion to form an electric field. It is preferable to provide a first placement portion on which one end portion of the member is placed, and a second placement portion provided on the second side wall portion and on which the other end portion of the electric field forming member is placed.

According to this configuration, both ends of the electric field forming member can be supported by the first placing portion and the second placing portion, respectively, so that the electric field forming member can be installed in a more stable posture.
In the container described above, the electric field forming member includes an insulating member having electrical insulation, and an electrode member fixed to the outer surface of the insulating member and forming an electric field based on the application of voltage. Of the electrode member and the insulating member, only the insulating member is preferably placed on the placing portion and the second placing portion.

According to this configuration, the electrode member can be installed on the mounting portion.
In the container described above, when the direction in which the first side wall portion and the second side wall portion face each other is defined as the predetermined direction, the insulating member has a shape longer than the electrode member in the predetermined direction. Both ends of the insulating member in a predetermined direction are preferably placed on the placing portion and the second placing portion, respectively.

According to this configuration, it is possible to easily realize a structure in which only the insulating member, out of the electrode member and the insulating member, is placed on the first placing portion and the second placing portion.
In the container described above, the insulating member is preferably entirely made of an insulating material. Alternatively, the insulating member is preferably formed by applying an insulating material around a predetermined material.

In the container described above, the first mounting portion is a member having an L-shaped cross section and having a portion fixed to the first side wall portion and a portion on which one end portion of the electric field forming member is placed. The placing portion is preferably a member having an L-shaped cross section, which has a portion fixed to the second side wall portion and a portion on which the other end portion of the electric field forming member is placed.

According to this configuration, it is possible to easily realize a placement section on which the electric field forming member can be placed.
In the container described above, it is preferable that the placement section is made of an insulating material having electrical insulation.

According to this configuration, it becomes difficult to form an electric field from the electric field forming member toward the mounting portion. As a result, a more uniform electric field can be formed inside the container.
It is preferable that the storage container is a new or second-hand product.

According to the container of the present invention, it becomes possible to arrange the electric field forming member more easily.
