The box 1 is composed of a cardboard sleeve 2 having a rectangular cross section. The sleeve has two separate stop members 3 forming the base and lid of the box. A combination of

The sleeve 2 is manufactured, for example, from a piece of pole paper material, as shown in FIG.

This sleeve has four rectangular side walls 21, 22 separated from each other by fold lines. ．． 23 and 24, and locking tabs 25 are extended on both sides of each side wall. Place it.

The width a of each tab 25 is set smaller than the width of the side wall 21.22.23.24. Ru. The tabs are separated from their associated side walls by fold lines and each have a rectangular opening 26. The free side of the side wall 24 has a tertiary structure in the vicinity of the central region. Once the original shape is given, the side walls 24, 21 are tied together using adhesive or a stapler, for example. A mating tongue-shaped extension 27 is provided.

When this connection is completed, the side walls are folded back to each other and have a rectangular cross-sectional shape as shown in the illustration. After the sleeve is formed as a parallelogram, the tabs 25 are folded back inward and shown in FIG. Obtain the structure of the example. The width of this tab 25 folded inward is equal to the width of the side wall. This is possible because the diameter is also small.

Thus, each end of the sleeve 2 has a set of four tabs 25 on the walls 21,22. 23 and 24, and each tab controls the cardboard material in that area. The thickness will be doubled.

Since the tab 25 is connected to the side wall of the sleeve by the end fold line, the tab 25 has a certain elasticity and a slight tendency to free movement.

The opening 26, in particular its outer edge 28, locks the stopper member 3 to each end of the sleeve. function as a means of

1st. 3. Figures 4 and 5 show one possible embodiment of the stopper member 3.

The stopper member 3 has the same structure for the base and the lid. The stopper member is , the central body 31 is molded from a plastic material and has a substantially parallelepiped shape. It is desirable to configure the

The stopper member is formed to a size that fits inside the end of the sleeve 2.

This central body 31 is combined with a flat surface 32 forming a base or cap; The flat surface defines a peripheral shoulder 33 by having larger dimensions than the central body 31. The structure shall be such that the

That is, the dimensions of the cap 32 correspond at least to the dimensions of the sleeve 2, and , the shoulder 33 is positioned to abut against the edge 4 or 5 of the sleeve. .

In the embodiment shown in FIG. 1, the dimensions of the flat surface 32 are approximately the same as those of the sleeve 2. Ru.
