Description

  In particular, the present invention relates to a packaging container that is used to contain cooked rice, food, etc. and serve as a lunch box during Buddhist events, festivals, celebrations, vacations, and the like.

In general, the packaging container used to store rice and dishes and serve as lunch boxes for Buddhist events, festivals, celebrations, vacations, etc. is made of rectangular cardboard made up of a bottom wall and side walls. It is comprised from the container main body and the container lid body made from the rectangular cardboard which consists of an upper wall part and a side wall part.
In this packaging container, an inner container made of synthetic resin having a partition wall is placed in the container body, and cooked rice and dishes are placed at appropriate locations in the inner container, and then the container body is covered with a container lid. And offers.

On the other hand, when the packaging container is transported to a restaurant, a caterer, etc., the container body and the container lid are separated and transported in a stacked state. Further, in restaurants, caterers, etc., the container main body and the container lid are separated and stored in a stacked state.
In addition, consumers who purchase lunch boxes from restaurants, caterers, etc., separate the container body and the container lid, and put them in the form as it is, or crush them, and put them in garbage bags, trash cans, etc. for disposal It was like that.

However, separating the packaging container into a container body and a container lid, and transporting and storing them in a stacked state, they are very bulky, so they take up space, transportation costs, The storage cost was inevitably high.
In addition, it is separated into a container body and a container lid, and it is very bulky even when it is discarded as it is or crushed, put into a garbage bag, a trash box, etc. In addition to being difficult to handle, the amount that could be stored in the garbage truck was inevitably reduced.

Therefore, it consists of a main box body part in which opposing side walls are connected via a bottom wall, and a sub box body part in which a half bottom wall is connected to the side wall. The thing which comprises a container main body by fitting with the groove part of a side wall is proposed (refer patent document 1).
In addition, the bottom wall of the container body can be opened and closed, a fold curve is formed on the side wall, the bottom wall is opened, the side wall is then folded inside the container body via the fold curve, and the other side walls are subsequently folded in turn. There has been proposed one in which the container body is folded (see Patent Document 2).

According to these packaging containers, at the time of transportation and storage, the container body can be unfolded or folded into a flat state. , Storage costs can be reduced.
In addition, since the container body can be unfolded or folded into a flat state when discarded, it does not become so bulky even when thrown into a trash bag, trash box, etc. The amount that can be accommodated in the vehicle also increases.

A packaging container comprising: a container main body comprising a locking piece for engaging the reinforcing plate; and a container lid comprising a top wall portion and a side wall portion separately from the container main body. And
The side wall portion of the container body is a plate material having a rectangular shape made of thick paper,
The bottom wall portion of the container body is composed of two opposing bottom wall dividing plates made of thin paper having the same shape, and each of the bottom wall dividing plates is adjacent to the side wall portion of two adjacent container bodies. It is fixed, and a fold line is formed from its peripheral vertex to its hypotenuse,
The reinforcing plate of the container body is a board made of thick paper, and consists of a placement part and an end piece part, and the end piece part is fixed to the inner side surface of the side wall part of the container body , A fold line is formed at the boundary between the placing portion and the end piece,
The locking piece of the container body is a board made of thick paper, and is fixed to the inner surface of the side wall portion of the container body ,
By flattening the bottom wall dividing plate, lowering the reinforcing plate of the container body, and contacting the upper surface of the bottom wall dividing plate, the container body can be assembled and put into use,
The container body is flattened by raising the reinforcing plate of the container body, folding the bottom wall dividing plate, bringing the bottom surfaces of the bottom wall dividing plate into contact with each other, and bringing the inner surfaces of the side wall portions of the container body into close contact with each other. As a shape, the container body can be transported or stored.

The bottom wall dividing plate is formed with a contact piece from the midpoint of the hypotenuse to one end, and in the state where the bottom wall dividing plate is flattened, the other base is located in the region near the hypotenuse of one bottom wall dividing plate. It is preferable that the abutting piece of the wall dividing plate abuts.

The packaging container may be a packaging container having a square shape or a rectangular shape when viewed from above.

Further, the packaging container is a packaging container having a hexagonal shape when viewed from above , and further, as a bottom wall dividing plate constituting the bottom wall portion of the container body , and further, the side walls of two opposing container bodies The periphery may be fixed to the portion , and a bottom wall dividing plate having a folding line formed in the middle may be provided.

According to the packaging container of the present invention, it is possible to fold the container body into a flat state during transportation and storage. Cost can be reduced.
Furthermore, according to the packaging container of the present invention, the container main body can be folded and the container main body can be assembled by an extremely simple operation.
