Abstract

PROBLEM TO BE SOLVED: To solve such a problem that in the case of a double container-like cooked food container constituted by allowing an inner container made of cardboard and formed into a container shape by raising a side face portion at each side of an outer circumference of a bottom face portion to be contained in an outer container, each side face portion of the inner container has heretofore fallen inward, so that the appearance of the cooked food container becomes poor. SOLUTION: The cooked food container is formed out of a double container consisting of an outer container 1 having shape-retaining characteristics and an inner container 2 made of cardboard. An inner container material 20 to be sued for the inner container 2 is made by integrally cutting the cardboard to form a bottom face portion 21, each side face portion 22 connected respectively to each side of an outer circumference of the bottom face portion 21, each fold piece 25 which allows base end parts of mutually adjacent side edges 23, 24 of the respective side face portions 22 to be connected to each other, and each extending portion 26 connected to either side edge of both the adjacent side edges 23, 24 of the respective side face portions 22. By folding the fold pieces 25 and the extending portions 26 on outer faces of the inner container 2 at its corner parts in mutually opposite directions on the right and left sides under the condition that the inner container 2 is formed with the inner container material 20, each side face portion 22 is prevented from falling inward.

The present invention has the following structure as means for solving the above-mentioned problems. still,
The present invention is directed to a food container comprising a double container of a shape-retaining outer container and a cardboard inner container accommodated in the outer container.

The outer container can be made of any suitable material as long as it has a shape-retaining property. Further, as the outer container, a suitable polygonal one can be adopted as long as the outer peripheral shape is a triangle or more.

As the inner container, a cardboard (laminated paper) having a waterproof surface on one side serving as an inner surface is used. The inner container has a bottom portion having the same shape as the bottom plate of the outer container, each side portion continuous with each outer peripheral side of the bottom portion, and a base end portion of each side edge adjacent to each side surface portion. The folded folds and the extending portions connected to either one of the adjacent side edges of each side surface are integrally cut and formed.

In this inner container, the inner container is formed by erecting each side surface portion with respect to the bottom portion, and at this time, each fold portion and each extension portion are mutually connected on the outer surface of the corner of the inner container. Bend to the opposite side. In this manner, when the folds and the extending portions are respectively bent to the left and right opposite sides on the outer surfaces of the respective corners of the inner container, the left and right edges of the respective side surfaces of the inner container are folded. Alternatively, the extension portions are engaged with the side edges of the side surfaces on the other side, and the side surfaces do not fall inward. Therefore, when the inner container is housed in the outer container, each side surface of the inner container fits neatly along the inner surface of each side plate of the outer container. In addition, each fold fold prevents liquid leakage from the corners of the inner container (abutting portions of the side edges of the side surfaces).
