Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin container used for transportation and storage of so-called pure packs or PET bottles for drinks, which are packs of beverage paper such as milk and juice. And a container made of synthetic resin which is convenient for taking out.

[0002]

2. Description of the Related Art Conventionally, transportation of pure packs such as milk,
As the synthetic resin container used for storage, a container as shown in FIG. 8 is often used. That is, the container is a bottomed container having an open upper surface, and the handle hole 2 is provided in the upper portion of the side wall 1, and the outer surface of the side wall 1 is reinforced by the rib 3.
Twelve 1 liter pure packs in these containers,
Alternatively, 20 500 ml pure packs are stored and transported and stored. When used as a display, the containers are used in a two-tiered manner with the containers facing sideways as shown in the figure.

[0003] On the other hand, as a container in which the contents can be taken out from the side while the containers are stacked upward without being horizontally stacked, for example, there is a bottle transportation container described in Japanese Patent Publication No. 52-16035. As shown in FIG. 9, this container is formed with corresponding windows 4 on both side walls of the container body into and out of which bottles can be taken in and out. A partitioning frame 6 is provided integrally with the horizontal thread 5 so that the partition frame 6 is engaged and mounted so as to be able to move up and down, and divides the bottle between these two horizontal thread 5. When storing a bottle, insert it through the top opening like a normal container, and when removing a bottle, raise the crossing member 5 to raise the window 4.
It was designed so that the bottle could be taken out while tilting the bottle.

[0004]

However, the conventional container has the following problems. That is, the pure pack container shown in FIG. 8 has a structure in which the handle hole 2 is provided in the upper portion of the side wall and most of the side wall is closed, like other commonly used synthetic resin containers, and therefore the stored items are Is difficult to see. Therefore, the brand, type, etc. of the Pure Pack cannot be discriminated and cannot be confirmed unless it is taken out from the container. In addition, as described above, most of the side walls are closed and the stored items cannot be seen, which makes it unsuitable as a display container. Further, since the side wall has a rib structure, there is a problem that dust is likely to be attached and dirt is conspicuous. Furthermore, in the case of a small pack such as 500 ml, it has to be taken out of the container and exhibited.
There was a problem that it took time.

In the bottle transporting container shown in FIG. 9, although the size of the window can be changed, a handle 7 is formed on the upper part of the window, and moreover, between the crossing members 5. The partition frame 6 is integrally formed. Therefore, the lateral wall 5 and the handle 7 are provided at the upper part of the side wall with a constant height. For this reason, when taking out the bottles, the bottles must be tilted to be taken out one by one from below the cross member 5, and the more the bottles at the back, the more difficult it is to take out. Also, a container with a thin upper part such as a bottle has a gap in the upper part, so you can tilt it by holding the neck part, but in a pure pack such as milk, it is close to each other and there is no gap to put your hand in, so hold it in your hand. You cannot tilt it. Therefore, there is a problem that the bottle transport container cannot be applied to a pure pack storage container.
