Description

[Detailed Description of the Invention] This invention relates to an assembly type storage case mainly for storing bagged tea leaves and sweets.

In conventional cylindrical tea cans, confectionery cans, etc., the body and the bottom body are connected and integrated, and the contents can be taken out only by opening and closing the lid. For this reason, the shape of the fuselage was always the same and could not be bent, resulting in the drawback that it required a large storage space when stored.

In the present invention, the body is made into a foldable polygon, and the means for fitting the lid body and the bottom body to the body body is extremely simple and can be fitted firmly.
This provides an assembly type storage case that can be manufactured at low cost.

A specific example of the present invention will be described with reference to the drawings. The storage case is composed of a body 1, a lid 2, and a bottom 3. Although this specific example uses a regular hexagonal storage case, other polygonal storage cases may be used.

The body 1 is formed by carving parallel fold lines a of the same width on a rectangular sheet made of, for example, slightly thick cardboard, which has some repetition force 6
It is divided into a surface and a gluing part b. The sheet c with the fold line can be stored as it is, or the glued part b is glued to the opposite side to form a cylindrical polygonal body, and then folded in half along the fold line a. Sometimes, it is combined with a lid body 2 and a bottom body 3, which will be described below. The body 1 usually has an appropriate pattern, letters, etc. applied to the exposed surface.

The lid body 2 and the bottom body 3 are formed by injection molding of synthetic resin, and have a symmetrical shape except for a part.

The lid body 2 has a regular hexagonal upper surface 4, and an outer wall 5 of the same length, for example, about 8 mm, is suspended from the entire periphery of the lid body 2. The inner periphery of the outer wall 5, particularly the inner surface of the periphery, is dimensioned so that the outer surface of the end edge of the body 1, which has a regular hexagonal cross section, can slide into it without being damaged.

Inside the outer wall 5, an inner wall 6 is suspended from the back surface of the upper surface 4 so as to form a regular hexagonal fitting groove 9 between the outer wall 5 and the inner wall 6. The hanging length of the inner wall 6 is, for example, about 13 mm, which is longer than the length of the outer wall 5, and the outer periphery of the inner wall 6, especially the outer surface of the periphery, is damaged. The dimensions shall be such that it can slide in without being given any.

Therefore, the fitting groove 9 formed over the entire length between the outer wall 5 and the inner wall 6 has a regular hexagonal shape that is slightly wider on the inside and outside than the thickness of the hexagonally expanded body 1.

In the present invention, a protrusion 8 and a protruding wall 7 are formed on the inner surface of the outer wall 5 and the outer surface of the inner wall 6 forming the fitting groove 9, respectively. The protrusion 8 is provided on a partition between the six faces, and is formed approximately in the center of the formed face. On the other hand, the protruding wall 7 is constructed as a wide inclined surface whose thickness gradually increases from the outer tip of the inner wall 6, and is arranged at the same position on each of the six surfaces, that is, deflected in one circulation direction.

Therefore, the remaining part other than the protruding wall 7 formed in the fitting groove 9 becomes a smooth surface, and the insertion opening 1 is formed as a smooth surface.
The gluing part shall be inserted into 0.

That is, the width of the insertion opening 10 is formed to be equal to or wider than the width of the gluing portion b, and the insertion opening 10 is wider than the other fitting grooves 9 other than the opening. Since it has a groove shape, the gluing portion b can be smoothly inserted into the insertion opening 10.

Therefore, when the end edge of the hexagonally expanded body portion 1 is slid into the fitting groove 9, the end edge other than the insertion opening 10 into which the gluing portion b is fitted will be connected to the protruding wall 7 and the protrusion 8.
It is held in such a way that it can be freely fitted into the gap. On the other hand, the gluing part b of the body 1 is a double wall, and by arranging the end edge of the double wall part so that it can be inserted into the insertion opening 10 in the fitting groove 9, the double wall part The end edge portion of the double wall portion runs along the outer surface of the inner wall of the insertion port 10, making it easy to insert the double wall portion.

The bottom body 3 is made of the same material and has an overall symmetrical shape compared to the lid body 2, but differs only in the arrangement of the protrusions 8 and the direction of the protruding wall 7.

That is, in the lid body 2, the protrusions 8 are formed on each partition surface of the inner surface of the outer wall 5, but in the bottom body 3, they are formed not on the partition surfaces but on each surface. Therefore, the bottom body 3 has more protrusions 8 than the lid body 2, and when assembling the case,
The bottom body 3 is more firmly fixed to the body 1 than the lid body 2.

Due to this difference in the degree of fixation, when you put your finger on the outer wall surface of the lid 2 and bottom 3 of the assembled case and pull them in the opening direction, the frictional force on the lid 2 is less than that on the bottom 3, so the lid 2 is opened, so there is no confusion between the lid body 2 and the bottom body 3. Also, the inner wall 6 is replaced by the outer wall 5.
Since it is suspended longer, the inner wall 6 plays a guiding role, and fitting of the body 1 with the lid body 2 and the bottom body 3 is extremely easy. Furthermore, since any of the insertion ports 10 of the lid body 2 and the bottom body 3 other than the protruding wall 7 comes into contact with the double wall of the body 1, the body 1 and the lid body 2,
This provides excellent effects such as no need for positioning with the bottom body 3.
