Description

The present invention relates to a food packaging container using a box-shaped wooden thin plate, and more particularly to a wooden folding planar food packaging container that can be folded and stored when not in use.

In a conventional foldable wood lunch container, a folding groove is formed on one surface of a plate material, and both ends of the plate material are bent by this folding groove to form a pair of side walls and a bottom surface of the lunch container. That is, symmetrical folding grooves are formed at positions close to both ends in the short direction of the plate material, and both ends of the plate material are bent by the folding grooves so that the cross section exhibits a U-shape in a state where both ends of the plate material are upright. . In addition, a method of closing both ends in the longitudinal direction with a paper material has been proposed.

To provide a packaging container that can be easily opened and has a low risk of breaking a stored bag member or the like. In order to provide a packaging container that can be opened without requiring a large pushing force, a pushing member that accommodates a bag member that is folded at the end and is bent by forming a part of the periphery by a boundary line that is easy to shear. A packaging container that is opened by tearing from the push-in part, and at least a first folding part and a second folding part following the first folding part are formed at the end of the bag member Thus, a packaging container is provided in which a space is formed inside the push-in portion in the packaging container, and the size of the push-in portion is such that the pushed-in push-in portion does not contact the end of the bag member. (See Patent Document 1).

For the purpose of providing a container for food wrapping using a warp that can be easily folded, from both ends of the outer surface of the tree with paper on the inner surface, it should be perpendicular to the fiber direction of the tree, where it is worth the depth of the container. Make a cut or V-cut into, and bend both ends inward to make the bottom and side plates of the container. To make it possible to raise both sides of the board vertically from the bottom and to bend it inward, paste the paper on the side of the end of the board while raising both sides of the board vertically from the bottom. Fix it. Thus, a container has been proposed in which both side plates connected to the bottom rise vertically from the bottom and do not fall outward, but can be folded only inside (see Patent Document 2).

By connecting the storage recess for storing rice and the storage recess for storing side dishes with a hinge as a food container that is easy to take home by changing the width of the container while maintaining the display effect of food packaging containers such as one-way lunch boxes. There has been proposed one that can be folded and stacked, and at least one of the storage recesses is covered with a lid so that the folding work can be easily performed (see Patent Document 3).

Four corners at the bottom to provide a unique folding food container that has been assembled and is easy to wash after use, with a single sheet material that is easy to wash and easy to store. Left and right walls and front and rear walls are provided via folds in the direction, and the folding part at the tip, which is an extension of the front and rear walls, is folded inward, and fastening parts are provided on the inner side of the folding part and inside the front and rear walls. A foldable food container of a sheet material has been proposed (see Patent Document 4).

A foldable lunch box that is folded when not in use and unfolded when in use, and without the need for a separate support plate in order to keep the lunch container unfolded as seen in the prior art. Provided is a wooden lunch container that can provide a stable unfolded state of the container. A wooden lunch box comprising a bottom surface, a pair of first side surfaces connected to both lateral sides of the bottom surface, and a pair of first side surfaces connected to both longitudinal sides of the bottom surface A plate material having two side surfaces, and a sticker between the bottom surface and the second side surface, and provided so as to keep the lunch container expanded together with the first side surface when deployed. It has been proposed to be configured by an end face sealing paper (see Patent Document 5).

In order to facilitate inventory control, there are various types of paper folding flat food packaging containers, but there is no thin wooden folding flat food packaging container. In particular, it has a problem in bending technology.
