Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container, for example, a packaging container used for packaging accessories such as a rod-shaped product or a tubular product, or a necklace.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 to 6, the packaging of a rod-shaped or tubular article, an accessory, etc., has a front wall (21) whose surface is curved forward and a surface. The rear wall (22) curved rearward and the folds (37) (38)
While forming a flat tubular body by being connected via the, the eye-shaped wall surface (23) (24) which is substantially orthogonal to the tubular body and curved inward is the upper and lower surfaces thereof. Packaging containers may be used.

This packaging container is made of a sheet material such as elastic cardboard or a synthetic resin sheet, and when it is expanded, a fold (37) is formed on one side edge of the front wall (21) as shown in FIG. ) Is connected to the rear wall (22),
A joining piece (31) is continuously provided at a side edge portion of the front wall (21) located on the opposite side to this side through a fold (38).
Also, arcuate folds (3
3) The eyelid-like lid pieces (23) and (24) are arranged in series via the (3) and (34). Similarly, eyelid-like lid pieces (25) and (26) are connected to the upper and lower edges of the rear wall (22) via arcuate folds (35) and (36), respectively.

The sheet on which each element is formed is
The front wall (21) and the rear wall (22) are folded back from the fold line (37), while the joining piece (3 is continuously provided on the side edge of the front wall (21).
1) is folded back from the folds (38) and attached to the side edges of the back surface of the rear wall (22), and eye-shaped lid pieces (25) continuously provided at both upper and lower edges of the rear wall (22). (26) is folded back from the arc-shaped folds (35) and (36), respectively, while the front wall (2
1) eye-shaped lid pieces (23) (2
4) is folded back from the arcuate folds (33) (34) and polymerized on the outer surfaces of the eyelid-like lid pieces (25) (26) of the rear wall (22), respectively. It is what is formed.

The eye-shaped lid pieces (23 to 26) are attached to the front and rear walls (2
1) Arc-shaped folds (33) on both upper and lower leg edges of (22)
~ 36), the front and rear walls (21)
When (22) is curved to form a flat tubular body, these eyelid lid pieces (23 to 26) are arcuate folds (23 to 26).
It can be folded inward from 26). Then, the folded back eyepiece lid pieces (25) (26) on the side of the rear wall (22) receive elastic restoring force from the front and rear walls (21) (22), so that the eyepieces of the front wall (21). The lid-like lid pieces (23) and (24) are locked to the lower edge portions on the back surface and are prevented from opening. In this way, the shape of this type of packaging container was secured by the engagement at the lower edge of the back surface of the eyelid-shaped lid pieces (23) and (24).

However, in this type of conventional packaging container, the elastic restoring force of the front and rear walls (21) and (22) is
Since the shape is always acting in the direction of flat folding, if the external force perpendicular to the front and rear walls (21) and (22) is applied, the above-mentioned locking is easily released and the shape is stabilized. It could not be held well. In addition, the polymerized eye-shaped lid pieces (2
3) (25), (24) and (26) are front and rear walls (21)
Since it is locked in a manner orthogonal to the tubular body formed by (22), the locking is weak, and the flat folded state may return to its original state unintentionally.

When a thick packaged object is placed in this type of packaging container, the vertical width of the eyelid lid pieces (23 to 26) must be wide according to the thickness of the packaged object. Therefore, a wider sheet is used for the production. In addition, widening the vertical width of the eyelid lid pieces (23 to 26) means that the arc-shaped folds (33 to 36) are formed at the upper and lower edges of the front and rear walls (21) and (22) having a constant height. It is nothing but the formation of a fold so as to make a deep cut from it, that is, the reduction of the curvature of the arc-shaped folds (33 to 36), and this change reduces the height of the wrapping target. It will end up. In other words, even if a wide sheet is used to wrap a thick object to be packaged, its height will be reduced. In addition, since the container in which the arcuate folds (33 to 36) are deeply formed in the front and rear walls (21) and (22) is formed with the four corners protruding sharply, it is inconvenient to handle. If stored in this state, useless space is formed in the vertical direction of the container.

Therefore, according to the present invention, the shape can be stably maintained, the sheet material can be saved, and the height of the wrapping object to be wrapped is not reduced. An object is to provide a packaging container that can be packaged.

[0009]

SUMMARY OF THE INVENTION The present invention provides an eye-shaped lid piece which is made of a sheet material such as a thick cardboard or a synthetic resin sheet having elasticity and which is continuously provided on both upper and lower edges through arcuate folds. In a packaging container comprising the front and rear walls, a projecting piece is provided on the outer edge of one of the front and rear walls, and the projecting piece is formed on the outer edge of the other ocular lid piece. The configuration is such that a notch portion into which is inserted is provided.

That is, according to the packaging container of the present invention, the projecting piece projecting from the outer edge of one of the front and rear walls of the eye-shaped lid piece is provided on the outer edge of the other eye-shaped lid piece. Since it is fitted in the notched portion, the projecting piece and the notched portion are strongly engaged with each other by the elastic restoring force of the front and rear walls, and the shape of the container is held very stably.
