Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container cover such as a shoulder cover, a one-touch cap or a spout for fixing a content to an aerosol container which sprays contents to the outside using a propellant.

[0002]

2. Description of the Related Art Conventionally, an aerosol container is fixed to the upper end thereof
One-touch cap that covers and protects the outer periphery of the push button,
A container cover such as a shoulder cover for protecting the outer periphery of the lid of the aerosol container and the outer periphery in the lower direction of the push button, a spout having a large-diameter tubular nozzle for injecting foamed aerosol contents and high-viscosity aerosol contents is used. ing. These container covers are firmly fixed to the lid at the upper end of the aerosol container, and are configured so that they cannot be easily removed. Further, the container cover is conventionally formed of a synthetic resin.

[0003]

However, the aerosol container is generally formed of a metal material, and the container cover is formed of a synthetic resin. Then, after the use of the contents of the aerosol container is completed, when the aerosol container is reused as a metal material, if the container cover is present,
A container cover formed of a synthetic resin and a metal aerosol container are mixed, which is not preferable for recycling.

Therefore, it is considered that the container cover is removed when the aerosol container is recycled. However, since this container cover is conventionally firmly fixed to the aerosol container,
It was not easy to remove it, and it was almost impossible by hand or the like. For this reason, there is a great hindrance to the recycling of the aerosol container.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention easily removes a synthetic resin container cover fixed to a metal aerosol container when the contents of the aerosol container are completely used. An aerosol container made of a metal material and a container cover made of a synthetic resin material can be easily separated. And, while the contents of the aerosol container are being used, the container cover can be securely fixed to the aerosol container without being easily separated from the aerosol container.

[0006]

According to the present invention, there is provided a synthetic resin container cover fixed to an upper end portion of an aerosol container and provided at a lower end of a container cover body in order to solve the above-mentioned problems. The lower edge of the skirt portion is arranged facing the tapered shoulder of the aerosol container, and a plurality of notches are formed in the lower edge, and a thin portion is formed vertically from the notch and the container is formed. The cover body is fixed to the aerosol container so as to be movable in the shoulder direction.

[0007] The skirt portion may be composed of an inner skirt fixed to the outer periphery of the lid of the aerosol container so as to be vertically movable, and an outer skirt arranged facing the outer periphery of the inner skirt.

Further, the container cover body may have a cover having a U-shaped cross section removably fixed to the upper end.

[0009] The container cover body may be a shoulder cover.

[0010] The container cover body may be a one-touch cap.

[0011] The container cover body may be a spout.

[0012]

Since the present invention is constructed as described above, when the container cover is to be fixed to the aerosol container, when the lower edge of the container cover is pushed from the upper end of the lid of the aerosol container, the skirt is formed. It is fixed in contact with the outer periphery of the lid. The fixing is performed by adjusting the lower edge of the skirt portion so as not to strongly contact the shoulder portion of the aerosol container. When the container cover is strongly pressed in the shoulder direction by a method such as hitting, the container cover is fixed so as to be movable in the shoulder direction. However, the container cover main body and the lid are fixed so as not to be moved by pressing during normal use without hitting or the like.

When the contents inside the aerosol container are used and the aerosol container needs to be discarded, the aerosol container is inverted and strongly hit the floor or the like, or the aerosol container is covered by an appropriate method. Press strongly in the direction of the tapered shoulder of the container.

Due to this strong pressing, the lower edge of the skirt portion is strongly pressed against the tapered shoulder portion of the aerosol container, and expands while sliding. Since the skirt portion breaks the thin portion from the cutout portion by this expansion, the container cover body can be easily removed from the aerosol container.

Then, after removing the push button and the like from the aerosol container, the aerosol container as a metal material is recycled,
It can be used as a metal material. Further, the container cover can be separated and reused as a resin material.
