Description

[Detailed description of the invention] A. Industrial application field The present invention relates to the structure of a food container suitable for parties, picnics, etc.

B. Conventional technology In general, in food containers in which multiple inner cases are stacked and stored in an outer case, the outer case is used only for storage and transportation, so when the container is opened at a party or picnic, the outer case gets in the way. Not only does it become difficult to dispose of, but it also has the disadvantage that if the inner case is placed directly on a table or the ground, the bottom surface of the inner case gets dirty.

C. Problems that the invention aims to solve This invention was made in view of the above problems, and its purpose is to create a frame that holds the inner cases in a lined state after the container is opened. This type of food container can be used as an outer case.

D. Means for Solving the Problems The food container according to the present invention is formed of an outer case and an inner case, and the outer case is stacked with a plurality of flat rectangular parallelepiped inner cases and placed in a removable manner. Cover bodies that cover the left and right halves of the top surface, both end surfaces, and each side surface of the stacked inner cases are formed on both sides of the printed circuit board so that they can be opened and closed, and the width W and thickness T of the inner cases and the number of stages are 2NT=(N-1)×W...(1).

E Effect According to the above configuration, when the outer case is opened left and right, the sum of the width 2NT of both side plates of the outer case and the width W of the board (2NT + W) is the width NW of N cases arranged horizontally. Since they are equal, all the inner cases are held side by side in the outer case.

F Embodiment Figures 1 to 3 show an embodiment of the present invention in which N=2, that is, two stacked layers, in which flat rectangular parallelepiped inner cases 1a and 1b are stacked in two layers. An outer case is formed by opening and closing cover bodies 3a and 3b connected to both side edges of the board 2 and covering the left and right halves and side surfaces of the upper surface and both end surfaces of the two stacked inner cases 1a and 1b. 4 are formed in a series from cardboard, and the width W and thickness T of the inner cases 1a and 1b is obtained by substituting N=2 into equation (1): W=4T...(2) The relationship is established. Each of the inner cases 1a and 1b may be provided with a lid, or only the uppermost inner case 1a may be covered with a lid plate or a cover film.

Further, as shown in FIG. 2, in order to lock both cover bodies 3a and 3b of the outer case 4 to each other, a locking piece 5 cut and raised from the folded part of one cover body 3a is attached to the other cover body. It is designed to be inserted into an insertion hole 6 provided in the body 3b, and when the container is opened, the locking piece 5 gets in the way, so it is stored in the original cut-and-raised part 7.

Figure 3 shows the inner cases 1a and 1 with the outer case 4 opened.
b are held side by side.As shown in the figure, when the outer case 4 is unfolded, the total length is W + 2T + 2T = 2W, so just hold the two inner cases 1a and 1b horizontally. It can be kept lined up.

In the embodiment shown in FIG. 4, the relational expression W=3T (3) holds true when N=3 in equation (1), and the end surfaces of the inner cases 1a, 1b, and 1c stacked in three stages are square. 3 with the outer case 4 unfolded.
The structure is such that it can hold the inner cases 1a, 1b, and 1c. In this embodiment, a handle 8 is provided by the same means as the locking piece 5.

G Effect As mentioned above, the food container according to the present invention stores the inner cases stacked in N stages in the outer case consisting of the substrate and both cover bodies, and the width W and thickness T of the inner case are
Since the relationship of 2NT=(N-1)×W is given to When opened from side to side, all the inner cases can be placed side by side on top of the outer case.
There is an advantage that the outer case can be used as a frame for placing and holding the inner case at picnics, outdoor parties, etc., without placing the inner case directly on the ground or table.
