SOLUTION: In a container vessel 10 which is opened at the top and constituted of the bottom plate 12 and the side walls 11 erected from the periphery of the bottom plate 12, ribs made of unit shapes are connected to each other at the rear face of the bottom plate 12 and regularly arranged. The unit shape is a polygonal form having more than a pentagonal form.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container container used for storing and transporting articles and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a box-shaped container container 100 injection-molded using a synthetic resin such as polypropylene resin or polyethylene resin has an open upper surface and side walls 101 provided on all sides. It has a box shape having a bottom plate 102, and the bottom plate 10 of this container container 100
2 has a low strength with respect to a load in a flat plate shape, and particularly has a low rigidity with respect to bending and the like. Therefore, as shown in FIG. 6 and an enlarged view of a portion C in FIG. 6, the frame 2 is surrounded by rectangular vertical and horizontal edge frames 103 and 104. On the back surface of the bottom plate 102, ribs 105 and 106, which are regularly connected vertically and horizontally and have a unit shape of a quadrangle, are erected to form a lattice shape. The ribs 105 and 10
6 has a shape having a vertically long height H, as shown in a sectional view taken along the line D-D of FIG. 7 in FIG.

A rib 1 having a vertically long height H as described above
Even with the structure in which 05 and 106 are provided, there is a problem that the load applied to the bottom becomes larger and the occurrence of bending becomes larger when the contained article has a considerable weight. Rib 10 to eliminate the above
The height H of 5, 106 is further increased to increase the rigidity.

[0004]

However, as the height H of the ribs 105 and 106 is increased as described above,
The rigidity with respect to bending and the like increases, and the problem of rigidity as a container container tends to be improved, but on the other hand, another problem occurs. That is, when the height H of the ribs 105 and 106 increases, the total height of the container 100 increases and the container 100 becomes bulky.

On the other hand, if the total height of the container 100 is suppressed, the occupancy ratio of the height H of the ribs 105 and 106 to the total height of the container 100 becomes high, and the height of accommodation is
That is, there is a new problem that the storage capacity decreases,
There is a problem that extra space is required for transportation and storage, and particularly in recent years, the use of automated warehouses and the like has increased, leading to an increase in distribution costs.

Further, in order to alleviate the above problems, the ribs 105, 106 are made thicker or the ribs 105, 106 are made thicker.
A method of reducing the interval (vertical and horizontal pitch) has been devised, but there are problems that the weight of the container container itself increases and that the raw materials used increase and the cost of the product increases. .

The present invention has been made in view of the above problems, and an object thereof is to solve these problems and reduce the capacity as in the conventional case. In other words, the present invention provides a container container in which the required rigidity is sufficiently secured and the weight can be reduced.

[0008]

In the container container of the present invention, an upper surface is opened, and a container container having a bottom plate and a side wall raised from the periphery of the bottom plate is provided, and a unit is provided on the back surface of the bottom plate. The rib composed of the shape,
It is characterized in that they are connected to each other, are arranged regularly and stand upright, and that the unit shape is a polygon of pentagon or more.

[0009]

In the container container of the present invention, since ribs each having a pentagonal or more polygonal shape are connected to each other on the back surface of the bottom plate and are arranged in a regular arrangement, the ribs are erected.
The necessary rigidity can be sufficiently secured and the weight can be reduced without reducing the storage volume of the article, which can suppress the cost increase of the product and bring great advantages in logistics such as storage and transportation. It is possible.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of the container container of the present invention. As shown in FIG. 1, this container container 10 is integrally molded by injection molding using a synthetic resin such as polypropylene resin or polyethylene resin, the upper surface is open, and side walls 11 are provided on all sides. It has a box shape having a bottom plate 12.

Around the bottom of the container container 10,
An edge frame including a vertical frame 13 and a horizontal frame 14 is provided, and the bottom plate 11 is stretched inside the edge frame. This bottom plate 11
As shown in the front view of the bottom plate of FIG. 2 when viewed from the bottom, ribs 15 each having a hexagonal unit shape are connected to each other and regularly arranged in a standing manner.

As shown in FIG. 3, the rib 15 has a hexagonal shape (indicated by diagonal lines), and each side of the hexagonal rib 15 is connected to each other as shown in the drawing. As shown in FIG.
As shown in FIG. 5, all have a shape in which the bottom plate 12 is shared.

As described above, the ribs 15 provided upright on the back surface of the bottom plate 12 of the container container 10 of the present invention are different from the ribs provided in the conventional container container in which the lattice-shaped unit shape is a square. , Even at the same height and wall thickness, rib 1
Since the cross-sectional quadratic coefficient with respect to the load in the vertical direction (height direction) of 5 is increased, sufficient rigidity with respect to the load can be secured.

In the above embodiment, the unit shape of the rib is hexagonal, but it is also possible to form a polygonal shape of pentagonal shape or more, and rigidity equal to or higher than that of this embodiment can be obtained. It is also possible to use ribs that can be used. Further, the ribs may not be the same kind of polygon, but two or more kinds of pentagonal or more polygons may be connected and regularly arranged to form a rib.

[0015]

In the container container according to the present invention, since the ribs each having a polygonal unit shape of pentagon or more are connected to each other on the back surface of the bottom plate and vertically arranged in a regular manner, the articles are accommodated. Without reducing the volume,
The required rigidity can be sufficiently ensured and the weight can be reduced, which can suppress the cost increase of the product and bring about great advantages in physical distribution such as storage and transportation. Therefore, it is suitable as a container container.
