Abstract

PROBLEM TO BE SOLVED: To effectively use a resource and minimize rubbish, which results from disposal after use, by reducing caps, which are resin caps fitted on the top of an aerosol container containing, for example, paint. SOLUTION: The cap made of a resin comprises an annular fitting portion 1, which fits on the top of the container, and a cap portion 2, which reaches the top of the fitting portion and is in the shape of an inverted glass. The entire cap is formed in a skeleton manner such that connecting portions 3 and spaces 4 alternate with each other in the periphery 2a and top 2b of the cap 2. By forming the entire cap in the skeleton manner, the amount of resin that is consumed in order to form the cap is reduced and, on the other hand, sufficient strength is ensured for the cap.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container cap adapted to be used, for example, over an aerosol container containing a paint, wherein the entire cap formed of resin is formed in a skeleton shape. It is.

[0002]

2. Description of the Related Art Conventionally, a cap attached to an aerosol container or the like is mainly made of resin, and is formed in an inverted cup shape to be fitted on an upper portion of the container. Generally, this kind of container is thrown away when the contents are used up, and at the same time, the cap is also discarded as waste. On the other hand, in recent years, resources have been used effectively, and there is a social demand for reducing the amount of waste.

[0003]

Based on the above-mentioned social demands, the present inventor has proposed the present invention in which the amount of waste is reduced as much as possible while the resources are effectively used. Is what you do.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an annular fitting portion made of resin and fitted on the upper portion of a container, and an inverted cup extending above the fitting portion. In the cap formed with the cap portion of the mold, the connecting portion and the space portion are alternately formed on the peripheral surface portion and the upper surface portion of the cap portion, and the entire cap is formed into a skeleton shape. A container cap is provided.

The cap of the present invention, in which the entire cap is formed in a skeleton shape as described above, has the necessary strength as a container cap by providing connecting portions alternately formed with the space portions, while forming the space portions. The amount of resin used is reduced accordingly. Therefore, even when the cap is discarded, the amount of dust can be reduced as compared with the conventional product. As described above, the present invention has solved the above-mentioned problem.

[0006] Further, the invention according to claim 2 in which a transparent or colored film, a film on which a predetermined printing is performed, or paper is applied to the entire surface of the skeleton-shaped cap, The strength of the cap can be increased, and the weight can be reduced as compared with the conventional cap.

[0007] When the film is transparent, the upper part of the container can be seen through the packaging state. When a colored film is used, for example, in a paint container, it can be visually recognized by using a film colored in the color of the contained paint. Further, in the case of a film on which predetermined printing has been performed, it is possible to make the display of the stored object be recognized.
In this case, by combining with the colored film, the recognition effect of the stored object can be further enhanced. Also,
According to the second aspect of the invention, substantially the same effects as those of the film can be obtained even when the paper is applied to the entire cap.

[0008]

FIG. 1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is a perspective view showing a second embodiment in which a transparent film is applied over the entire skeleton cap.

In the figures, reference numeral 1 denotes an annular fitting portion which is detachably fitted to the upper portion of a container (not shown), and 2 denotes an inverted cup-shaped cap portion extending above the fitting portion. 2, in both the peripheral surface portion 2a and the upper surface portion 2b, a connecting portion 3 of an appropriate width continuous with the fitting portion 1 and a space portion 4 of an appropriate size surrounded by the connecting portion 3 are alternately arranged in the circumferential direction. Provided.

The cap of the present invention, in which the cap portion 2 is formed in a skeleton shape by providing the connecting portion 3 and the space portion 4 as described above, is used for molding by the size of the space portion 4 as compared with the conventional product. The amount of resin used is reduced. The thickness of each part of the cap in the embodiment is the same as that of the conventional product, but the strength of the cap to cover the container is necessary and sufficient.

Next, a second embodiment in which a transparent film is applied to the entire cap will be described with reference to FIG. 2. The amount of resin used and the weight of the entire cap are increased by the amount of the film 5 covered. Nevertheless, the amount of resin used can be reduced as compared with conventional products. On the other hand, since the film 5 is adhered, the strength is increased and the handling is easy. Further, in the second embodiment, by selecting the type of the film 5 to be applied, as described above, for example, the paint container is colored so that the color of the paint can be recognized, or by using a film on which a predetermined print is applied. In addition, it is possible to provide an effect that a cap capable of recognizing the display of the stored object can be formed.

The film 5 covers the entire skeleton-shaped cap.
There are in-mold molding method and shrimp film attaching method as the means for applying the method. However, since these methods are well-known and commonly used, detailed description is omitted here.

Reference numeral 6 in the drawing denotes an undercut portion formed on the inner peripheral surface of the fitting portion 1. In implementing the present invention, the ratio of the connecting portion 3 and the space portion 4 and their shapes and arrangements,
Needless to say, the thickness of the cap is not limited to the illustrated form, and can be appropriately changed within a practical range according to the gist of the present invention.

[0014]

According to the present invention in which the entire cap is formed in a skeleton shape as described above, the strength required for the cap of the container is provided, but the amount of resin used for molding the cap can be reduced. . Therefore, the amount of waste when the cap is discarded is reduced. The present invention has excellent advantages as described above, and has an effect of being practically useful.
