Description

[Detailed Description of the Invention] The present invention relates to synthetic resin containers that can be stacked on top of each other, and more particularly, to synthetic resin containers that can be stacked on top of each other by mixing containers with different outer diameters.

In general, synthetic resin containers are slippery, so in order to prevent them from collapsing even when stacked on top of each other, a stack section is formed at the bottom of the containers that projects downward and is slightly shifted inward from the side walls.
A container having a structure in which this stack portion is fitted into an upper opening of a lower container is known.

Containers with this structure can be stacked with containers of the same shape and dimensions, but if the outer diameter dimensions differ, the dimensions of the bottom stack will naturally differ, and it is not possible to mix and stack large and small containers with different dimensions. will no longer be possible.

On the other hand, in recent years, as the variety of products such as drinking water and beer increases, the number of containers used to transport them also naturally increases.

However, in the case of containers having a stacking portion protruding from the bottom so that they can be stacked as described above, if the outer diameters of the containers are different, it is impossible to stack the containers on top of each other for transportation and storage.

Therefore, a large storage space is required, which causes problems such as poor transportation efficiency and uneconomical conditions, as well as poor work efficiency.

The present invention was developed in view of the current situation, and aims to solve the above-mentioned problems and provide synthetic resin containers that can be freely mixed and stacked even if the containers have different outer diameters. .

In order to achieve the above object, the present invention forms the inner surface of the upper edge of the side wall inward from the inner surface of the pillars at the four corners so that containers of smaller dimensions can be mixed and stacked at the upper opening of the container. It has a configuration in which the outside of the edge is a recess.

The following description will be made based on the illustrated embodiments.

FIG. 1 is a plan view, and FIG. 2 is a partial vertical cross-sectional view. The four circumferential side walls 25 are connected by pillars 24 at the four corners. A window 20 is provided at the top of the side wall 25, and the upper edge is a cross-sectional view. Letter-shaped handle part 26
It is said that

The lower edge of the container is provided with a lower horizontal flange portion 21 that is placed on the upper edge of the container, and the bottom portion 22 is formed with a stack portion 23 that protrudes downward. It protrudes slightly inwardly from the lower inner surface 25a of the side wall so as to fit into the opening.

Further, in detail, a stepped portion 27 is provided on the inner surface of the handle portion 26 at the upper edge of the side wall and is formed inward from the inner surface of the column portion 24, and a recess portion 28 is formed on the outer surface of the handle portion 26.

In the illustrated embodiment, the recess 28 is formed at the height of the handle 26 .

Since the lower inner surface 25a of the side wall 25 is formed on the same plane as the inner surface 24a of the support column, only the central portion of the handle portion 26 protrudes inward.

Since the inner surfaces of the side walls have the above structure, the distance X between the inner surfaces of the support columns 24 is larger than the distance Y between the inner surfaces of the handle sections 26.

That is, the handle portion 26 is formed inward from the support portion 24 by the shaded portion 29, and the lower horizontal flange portion of the container having the smaller outer diameter is placed in this shaded portion. Become.

Note that the stepped portion 27 may be formed perpendicularly to the inner surface of the side wall instead of forming an outwardly expanding slope as shown in the embodiment.

Further, the size of the window 20 can be formed arbitrarily, and the size and length of the handle are limited by the size of the window.

In FIG. 3, the handle portion 26 is formed inward from the support portion 24, as in the embodiment described above (see FIG. 2).
Whereas in the first embodiment, only the handle portion 26 is formed inwardly, a stepped portion 27 is also provided on the side wall 25, so that the side wall 25 also has a handle portion 26.
The width of the recess 28 is the same as that of the handle 26 and the side wall 2.
5 are arranged vertically.

Therefore, the recess 28 is also formed in the side wall 25 and reaches the horizontal flange 21.

Since this device has the above-mentioned structure, containers with smaller outer diameters can also be placed on the upper edge of the side wall, mixed with each other, and stacked, which is advantageous because it does not require a large space for transportation and storage. Efficiency and work efficiency can be improved.

In addition, since the outer surface of the handle is recessed, the width of the grip does not become unnecessarily wide, making it easy to hold when carrying.

When the containers are arranged side by side, the outer surface of the handle portion is made into a recess, so that a gap can be formed into which a hand can be inserted.

Furthermore, since there is no need to provide ribs on the inner surface of the container with this invention, the upper container can be loaded and unloaded by sliding it while holding one end up, which is convenient for work.
