Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a packaging container for storing a bouquet or the like.

(Prior Art) Recently, the custom of giving a bouquet of flowers as a gift on occasions such as celebrations has become established in Japanese society, and the bouquet is sent to the recipient in a packaging container.

By the way, packaging containers generally have a square prism shape. This rectangular prism-shaped packaging container is assembled by folding cardboard and securing the folded portions with metal fittings or adhesive.

However, in the case of packaging containers as mentioned above,
This requires the use of fasteners or adhesives in addition to cardboard, which poses a problem in terms of ease of assembly.

In addition, in the case of square prism-shaped packaging containers, although they have good stability, the surface area is large in order to secure a certain internal volume, so the compressive strength is weak against external forces inward of the packaging container. In order to maintain a predetermined compressive strength, the thickness of the cardboard must be increased, which inevitably increases the manufacturing cost of the packaging container.

(Problems to be solved by the invention) The present invention was made to solve the above problems, and it can be easily assembled without using fasteners or adhesives, and has good stability. The purpose is to provide a packaging container that has a high compressive strength against external forces.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention provides a columnar triangular packaging container formed by sequentially folding a piece of cardboard, which consists of parallel lines on the cardboard. Three fold lines are provided, defined by the three fold lines to form three rectangular parts with the same width and one rectangular part with a narrower width approximately half that. Three rectangular parts of the same width form a side wall part when assembled as a packaging container, and the remaining narrow rectangular part forms an overlapping part that overlaps the outside of the side wall part. An insertion hole is formed in the plane of the side wall portion where the overlapping portions overlap, an insertion piece to be inserted into the insertion hole is formed in the overlapping portion, and the side wall portion is located in the center of the side wall portion. Connecting one side of a triangular wall part of a triangle whose length of one side is the same as the width of the side wall part to both ends of,
The other two sides of the triangular wall part are foldably connected with triangular support parts that fit inside the side wall parts located on both sides of the three side wall parts when assembled as a packaging container, and the overlapping part At the end of the part, there is a right triangular part formed by an extension of the edge line of the overlapping part and a part having the same width as the overlap part, and a long piece on the long piece of the right triangular part. A reinforcing portion is formed by connecting the tongue portions, and the sheet of cardboard is sequentially folded in a certain direction along the three fold lines, the overlapping portion is overlapped on the outside of the side wall portion, and A triangular cylindrical body is formed by inserting the insertion piece formed at the overlapping part into an insertion hole drilled in the side wall part, and the triangular wall part is bent at a right angle and the support part connected to the triangular wall part is attached to the side wall part. The ends of the cylindrical body are closed by bending inward, the right triangular portion of the reinforcing portion connected to the overlapping portion is overlapped with the upper surface of the triangular wall, and the tongue portion is folded into the cylindrical body. It is as follows.

(Function) The present invention has the above-mentioned configuration, so that a packaging container can be easily assembled using a single piece of cardboard without using fasteners or adhesives.

In addition, since the packaging container is triangular prism-shaped,
Not only is stability improved, but the surface area required to maintain a constant internal volume can be minimized.
