That is, the container of the present invention is a box-shaped container in which a box body is formed by bending a cardboard, and the side wall of the box body is bent to form a space of 3 to 15 mm between the outer wall and the inner wall. The cardboard surface paper is made of impregnated paper impregnated with a water resistant resin, and a water resistant paper sheet with a water resistant surface is removably laid on the bottom of the box body. It is characterized by being

The corrugated cardboard that composes the box body of the present invention may have a normal corrugated cardboard shape in which corrugated paper is sandwiched between two sheets of paper, but at least the surface paper is impregnated with a waterproof resin, It is important to use what is said to be water resistant.

Since paper impregnated with a water-resistant resin has water resistance not only on the surface but also on the cross section, the box body formed by bending such a cardboard has a high water resistance as a whole. , Very easy to handle. That is, in the box body of the present invention, the water resistant surface (resin-impregnated surface paper side) can be exposed to the bottom and back surfaces (externally exposed surface), the outer wall and the inner wall by bending such a cardboard. is there .

The bottom surface of the box body is exposed with a back paper of cardboard, and a water resistant sheet is laid on the back paper. As the water-resistant sheet, of course, paper is used, but it may be made of one sheet of paper, or a laminated body of paper or a cardboard structure. It suffices that at least the surface is treated with a water resistant resin, but it is preferable to use one whose both surfaces are treated with a water resistant resin. Also, from the viewpoint of heat insulation, the intermediate cushioning material has a honeycomb structure. It is particularly preferred to use the formula cardboard. At least the surface of the surface paper of this honeycomb type cardboard needs to be treated with waterproof resin, but similar to the cardboard that composes the box body, impregnated paper impregnated with a waterproof resin is used for the front surface paper or front and back surface paper. Preferably. In the honeycomb type cardboard, laminated paper having a metal foil layer in the middle may be used for the front surface paper and / or the back surface paper in order to enhance water resistance.

[0008] Next, the container of the present invention is not only formed of cardboard having an air layer in its entirety, but also provided with a space of a certain thickness on the side wall of the box body, and thus has a very excellent heat insulating effect. Will be things. By inserting a honeycomb type cardboard into this space, shape stability and heat insulation can be further enhanced. Since this honeycomb-type cardboard is covered with water-resistant cardboard (the outer wall and the inner wall of the box body), it does not have to be particularly water-resistant, but similar to the honeycomb-type cardboard used as the water-resistant sheet. It is preferable to use those which have been treated to be water resistant.

The container of the present invention may have a lid body that is formed by bending a cardboard similar to the box body, and that fits the box body. In addition, in order to enhance the water resistance, it is preferable to insert the same honeycomb type cardboard as the honeycomb type cardboard used as the water resistant sheet.

Further, in the container of the present invention, a cardboard body that can be inserted into the opening of the box body with good compatibility may be attached to the central portion of the bottom back surface of the box body so that the container can be stacked and used. It is preferable that the cardboard body is made of water-resistant paper to form a box, and a honeycomb type cardboard is inserted into the box to have excellent water resistance and heat insulation. A cardboard body similar to the above may be provided at the center of the upper surface of the lid body, the lid body may be turned upside down, and the box body may be placed on the lid so that the containers can be stably stacked.

[0011] Incidentally, the inner box formed by folding a paper having water resistance on the surface may be inserted into the inside of the box body, and the bottom surface of the inner box may function as the water resistant sheet. By using this kind of inner box, it is possible to completely prevent the backside of the cardboard that composes the box body from being exposed, so not only can the water resistance of the container be ensured, but also the cleanliness inside the container can be ensured. Therefore, processed food products can be stored directly in the container. In order to improve the heat insulating property, a honeycomb type cardboard may be placed on the bottom of the box body, and a middle box may be placed on it, or a water resistant honeycomb type cardboard may be inserted into the inside box.

Here, the honeycomb-type cardboard may be any one in which the central cushioning material is formed so as to form a large number of independent spaces in the shape of a honeycomb, and the shape of this space is circular. Also, it may be polygonal.
