DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container, and more particularly, to a packaging container suitable for storing easily fragile items such as fruits such as figs.

[0002]

2. Description of the Related Art Conventionally, there has been known a packaging container having a substantially rectangular bottom shape such as a substantially rectangular shape and side walls rising from four sides of the substantially square bottom shape. Are known.

[0003] Such a packaging container is integrally formed of, for example, plastic or the like.

By the way, in the above-described packaging container, when fruits such as figs are stored in the packaging container, the side walls are prevented from bulging outward and being damaged. A large number of reinforcing ribs are formed extending from the bottom to the opening at predetermined intervals over the entire side wall.

For this reason, when an object is accommodated in the packaging container, the object comes into contact with the rib.

[0006] Here, when the object accommodated in the packaging container is a rigid body, the object is prevented from being damaged by contact with the rib, but the object accommodated in the packaging container is prevented from being damaged. In the case where is soft such as figs, there is a problem that the object is scratched and hurt by contact with the ribs.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a method in which an object to be housed inside is made of a kind such as a fig. It is an object of the present invention to provide a packaging container that does not have a risk of damaging an object accommodated therein even when the container is very soft.

[0008]

In order to achieve the above-mentioned object, according to the present invention, the invention according to claim 1 is characterized in that a substantially square bottom surface and four sides of the substantially square bottom surface are respectively provided. In a packaging container having four raised sidewalls, the packaging container is formed so as to rise from four corners of the substantially rectangular bottom portion, and is integrated with a joint portion between the four sidewalls. It has four pillars formed.

Therefore, according to the first aspect of the present invention, since the above-mentioned four pillars reinforce the whole packaging container, a predetermined interval is provided over the entire side wall portion so that the bottom portion is provided. Even if a large number of reinforcing ribs extending from the opening toward the opening are not formed, it is possible to prevent the side wall portion from expanding outward when an object is accommodated in the packaging container.

[0010] The invention according to claim 2 of the present invention has a substantially square bottom surface and four side wall portions rising from four sides of the substantially square bottom surface, respectively. In the packaging container, a groove is formed on an upper end surface formed by the four side walls.

Therefore, in the invention according to claim 2 of the present invention, since the groove is formed on the upper end surface formed by the four side walls, the groove serves to reinforce the four side walls. Even when a large number of reinforcing ribs extending from the bottom portion toward the opening are formed at predetermined intervals over the entire side wall portion, the side wall portion is formed when the object is accommodated in the packaging container. Swelling to the outside is suppressed.

The invention according to claim 3 of the present invention has a substantially square bottom surface and four side walls rising from four sides of the substantially square bottom surface, respectively. The packaging container has four pillars that are formed so as to rise from the four corners of the substantially square shape and are formed integrally with the joining portions of the four sidewalls. A groove is formed on the upper end surface formed by the side wall of the first embodiment.

Accordingly, in the invention according to claim 3 of the present invention, the four pillars and the groove formed on the upper end face are used to reinforce the entire packaging container including the four side walls. Therefore, even when a large number of reinforcing ribs extending from the bottom portion toward the opening are formed at predetermined intervals over the entire side wall portion, when an object is accommodated in the packaging container, Swelling of the side wall portion to the outside is suppressed.

That is, according to the first, second, or third aspect of the present invention, the side wall extends from the bottom to the opening at a predetermined interval over the entire surface of the side wall. Since there is no need to form a large number of reinforcing ribs, for example, even when a painful object such as a fig is stored, there is no danger of damaging the object stored therein.

In the case where the ribs are formed only on the bottom side of the substantially central portion of the side wall portion as in the invention of the fourth aspect of the present invention, the object housed inside is not much. Without damaging, the four side walls can be reinforced more strongly.
