Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a packaging container for accommodating small articles.

[Conventional technology]

Since the conventional packaging container emphasizes the functional aspect of packaging goods, the shape of the container is inevitably determined in relation to the goods, and the shape of the container itself has a sense of fun and playfulness. Was few.

[Problems to be solved by the device]

An object of the present invention is to make a container into a peculiar three-dimensional shape so that small articles can be gracefully displayed and packaged in a state of containing them.

[Means for solving the problem]

In the packaging container according to the present invention, a thin plate member having a specific shape is bent to form a pair of symmetrical triangular pyramids having opposite inner side surfaces, and the pair of oblique triangular pyramids are formed. It is characterized in that the opening portion of the triangular pyramid is closely attached to form a hexahedron.

〔Example〕

Hereinafter, the packaging container according to the present invention will be described in more detail with reference to examples.

A cardboard P which is a thin plate for making the packaging container of the present invention.
As shown in FIG. 1, two pairs of the first and second equilateral triangular portions 1 and 2 are paired with each other to form a vertex 1 with respect to the base.
0 and the other one side are shared and arranged radially, and two first equilateral triangular portions 1 are arranged in the center and are adjacent to each other. Therefore, the length of each base for the common vertex 10 in each of the first and second equilateral triangular portions 1 and 2 is equal. Each of the second equilateral triangular portions 2 is provided with a superposed portion 3 having a substantially equilateral triangular shape and continuously arranged in the circumferential direction around a common vertex 10 between the superposed portions 3. Is provided with a break 4. The first and second equilateral triangular portions 1, 2,
The polygonal line 5 is provided on all the continuous portions (the shared side portions) of the overlapping portion 3. At the bottom of the second equilateral triangular portion 2, a square portion 6 having the bottom as one side is continuously provided, and a polygonal line 7 is provided at the joint portion of the square portion 6 and the second equilateral triangular portion 2. It is provided.

In addition, a triangular insertion portion 8 smaller than a right-angled isosceles triangular portion 6a obtained by folding the square portion 6 in two by diagonal lines is continuously provided on the bottom side of the adjacent first equilateral triangular portions 1. A polygonal line 9 is provided in a continuous portion of the insertion portion 8 and the first equilateral triangle portion 1. Also,
A polygonal line 11 is provided in a diagonal line portion connected to one side of the triangular overlapping portion 3 in the square portion 6.

Then, one part which is line-symmetric with respect to the side (the part of the polygonal line 5) shared by the respective first equilateral triangle parts 1 is assembled as follows.

First, as shown in FIG.
Bend at 11 to bend the square portion 6 inward, and in this state, bend the second equilateral triangle portion 2 connected to the square portion 6 inward at the portion of the polygonal line 5 and at the same time to bend the first equilateral triangle portion. 1 is bent inward at a broken line 9 and the square portion 6 is folded in half at a broken line 11 and is inserted between the right isosceles triangular portions 6a.
Is inserted (see FIGS. 3 and 4). Next, as shown in FIG. 4, the overlapping portion 3 is bent inward at the part of the polygonal line 5 and is overlapped with the inside of the second equilateral triangular portion 2, so that the first equilateral triangular portion 1 is placed on the bottom surface. Then, an oblique regular triangular pyramid A whose one side surface is open is formed. That is, two of the three side surfaces of the oblique regular triangular pyramid A are formed into a right-angled isosceles triangle in which the square portion 6 is folded in half along the polygonal line 11, and the remaining one side surface is the second regular triangle. It is composed of the triangular portion 2 to form an equilateral triangle.

When the other part is assembled in the same manner as described above, as shown in FIGS. 5 to 7, a pair of symmetrical regular triangular pyramids having symmetrical inner side surfaces open. A is formed and a large opening 12 is formed in the center. Then, as shown in FIG. 5, the small article B is inserted through the opening 12, and the small article B is displayed or viewed in this state.

In the state shown in FIGS. 5 to 7, bending is performed at the part of the fold line 5 provided in the continuous portion of the first equilateral triangle portion 1 (the bending process is shown in FIGS. 8 to 10). The opening portions of the pair of the equilateral triangular pyramids A are brought into close contact with each other, and the portion of the second regular triangle portion 2 in close contact with each other or the square portion 6 in close contact with each other into a planar shape is folded in two. When the oblique sides of the right-angled isosceles triangle portion 6a are connected by the seal pieces 13 so as not to separate from each other, a regular square pyramidal packaging container C as shown in FIG. 11 is obtained. That is, the four side faces of this right square pyramid are the two first equilateral triangle parts 1,
It is composed of two second equilateral triangular parts 2, and the bottom surface of the right square pyramid is formed into a planar shape by adhering the hypotenuse of the right-angled isosceles triangular part 6a obtained by folding each square part 6 in two. ing. This embodiment is a special case in which the oblique side of each right-angled isosceles triangle portion 6a obtained by folding the square portion 6 into two halves is brought into a planar shape.

In this way, the small paper B is wrapped by folding the thick paper P into a square pyramid shape.

Further, even if the above equilateral triangular parts 1 and 2 are made into an isosceles triangular shape, the same regular square pyramidal packaging container as described above can be obtained. However, the ratio of the height of the formed right square pyramid to one side of the bottom surface is larger than that of the above-described embodiment, and the shape becomes taller.

In this way, when the first triangular portion having the bottom portion connected to the insertion portion and the second triangular portion having the bottom portion connected to the square portion are formed into a congruent isosceles triangle, a quadrangular pyramid is formed. Has a square base, and each side has the same shape of an isosceles triangle, so that the axis is a right square pyramid (pentahedral) whose axis is perpendicular to the bottom.

In the thin plate member P'shown in FIG. 12, the first triangular portion 21 and the second triangular portion 22 have the same base length with respect to the apex 10 'that is shared, but the shapes of both are the same. While being completely different, a rhombus portion 23 having the bottom side as one side is continuously provided on the bottom side of the second triangle section 22.
The insertion portion 24 is continuously provided on the 21. When the openings of a pair of symmetrical triangular pyramids formed by assembling the insertion portion 24 are brought into close contact with each other, a hexahedron having a general shape is formed. The 12th
As shown in the figure, the overlapping portion 3 in the above embodiment
Is not always necessary.

Further, the material of the thin plate body is not limited to cardboard, and may be a foldable plastic plate or the like. Especially when a transparent plastic plate is used, there is an advantage that small articles inside can be seen in a packaged state. is there.

[Effect of device]

As described above, in the packaging container according to the present invention, a thin plate member having a specific shape is bent to form a pair of symmetrical triangular pyramids having symmetrical open sides, and the central portion is formed. A small article can be put into the hexagonal shape by putting the small articles into the hexagonal shape by adhering the openings of the pair of oblique triangular pyramids to each other for display and viewing, and by adhering the small articles through the formed large opening. Therefore, the packaging container has a unique shape when it is rarely packed and when it is packaged, and has a high taste.
