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 which can be stacked by inserting and fitting one synthetic resin container into the other synthetic resin container.

[0002]

2. Description of the Related Art Conventionally, for example, synthetic resin buckets, tarais, garbage containers, etc., or synthetic resin containers such as lids thereof are bulky, so that transportation cost can be reduced, or
In order to reduce the storage space and the like, as shown in FIG. 6, the synthetic resin container-like objects 1, 1, ... Are generally fitted and stacked in many cases.

However, the synthetic resin container 1,
When 1, ... Are fitted together and stacked, the mating surfaces of the synthetic resin container-shaped objects 1, 1, ... Are in close contact with each other, and one synthetic resin container-shaped object 1 is to be removed. Then, the gap S between the bottoms of the synthetic resin container-shaped objects 1, 1, ...
A great deal of force is required to remove one synthetic resin container 1.

When the synthetic resin container-like objects are fitted and stacked in this way, a separating tool as described in Japanese Utility Model Laid-Open No. 4-128160 is also used to remove the synthetic resin container-like products. Proposed.

[0005]

However, when the synthetic resin containers are stacked by being fitted to each other,
Do not always carry a separation tool with you to remove the synthetic resin container, and insert the separation tool if there is no flange that allows you to insert the separation tool as a synthetic resin container. If the thin synthetic resin container is removed with a separating tool, the synthetic resin container may be damaged.

The present invention has been made by paying attention to the problems in the conventional container made of synthetic resin.
The purpose is to solve the above problems and to stack synthetic resin containers when they are fitted together.
It is an object of the present invention to provide a synthetic resin container-like product which can be easily removed from the synthetic resin container-like product and does not require a separating tool or the like.

[0007]

In order to achieve the above object, the stackable synthetic resin container of the present invention has one synthetic resin container in which the other synthetic resin container is placed. In a container made of synthetic resin that can be stacked by inserting and fitting, a fine convex portion is provided on the fitting surface.

In the present invention, the synthetic resin container-like object includes a container-like lid such as a bucket, a tarai, a garbage container, and the like. In the present invention, the material of the synthetic resin container is not particularly limited, but for example, hard vinyl chloride resin, polyethylene, polypropylene, polystyrene, ABS resin, polycarbonate, etc. can be preferably used.

In the present invention, the height of the fine projections provided on the fitting surface of the synthetic resin container-like article is preferably kept within 1 mm, and when it is higher than 1 mm, A so-called sink mark in which the back surface is depressed is often generated, and conversely, if it is too low, the effect of the present invention may not be expected, so normally 0.3 to
About 0.6 mm is suitable.

[0010]

In the stackable synthetic resin container-like object of the present invention, since the fitting surface is provided with the fine convex portion,
Since the synthetic resin container-like objects do not adhere to each other on the fitting surface, they can be easily removed.

[0011]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the stackable synthetic resin container-like product of the present invention, and FIG. 2 is a bottom view of the stackable synthetic resin container-like product of the present invention. In FIGS. 1 and 2, reference numeral 1 is a lid of a polyethylene bucket which is a stackable synthetic resin container of the present invention. Side wall 11 of lid 1
Rib-shaped projections 12, 1 at equal intervals at three locations on the inner surface of the
2 and 12 are projected. In addition, 13 is a recessed portion on the back surface of the handle 14 provided at substantially the center of the lid 1.

As shown in an enlarged view in FIGS. 3 and 4, the rib-shaped convex portion 12 is provided on the inner surface of the side wall 11 of the lid 1 from its lower end to a middle portion, and its cross-sectional shape is substantially trapezoidal. Convex part 1
The protrusion height H of 2 is 0.6 mm, the width W of the top surface of the protrusion 12 is 2 mm, the outer diameter D of the lid 1 is 250 mm, and the height h of the side wall 11 is 2.
₁ is 14 mm, and the length h ₂ of the convex portion 12 is 8.1 mm.

[Operation of Embodiment] The operation of the lid 1 which is the container-like synthetic resin container that can be stacked according to the present invention shown in FIGS. 1 to 4 will be described with reference to FIG. As shown in FIG. 5, the side wall 1 of the lid 1
Since the convex portion 12 is provided on the inner surface of 1, the lower end of the convex portion 12 of the upper lid 1 contacts the upper surface of the lower lid 1 when the lids are stacked, and the upper lid 1 is placed on the lower lid 1. They will float and will not fit together. Therefore, the gap between the inner surface of the upper lid 1 and the upper surface of the lower lid 1 becomes normal atmospheric pressure, and the upper lid 1 can be easily removed from the lower lid 1.

The embodiments of the present invention have been described above with reference to the drawings. However, the specific configuration of the present invention is not limited to the illustrated embodiments, and design changes within the scope not departing from the gist of the present invention can be made. Included in the invention. For example, as in the illustrated embodiment, the convex portions may be provided at one place, two places, or four or more places instead of being provided at three places, and may be appropriately determined depending on the size of the container-shaped object or the like.

The shape of the convex portion is also the same as in the illustrated embodiment.
Instead of the rib shape, it may be a protrusion shape, and various shapes can be used.

[0016]

EFFECTS OF THE INVENTION In the stackable synthetic resin container-like object of the present invention, since the fitting surface is provided with the fine convex portion, the synthetic resin container-like objects do not adhere to each other on the fitting surface. And can be easily removed.
