Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container that can be separated and discarded, and more particularly, to a container that can easily separate and discard an aerosol container body and a valve case when the container is discarded.
[0002]
[Prior art]
As a conventional technique, there is an aerosol container as shown in FIG. 8, and a bead portion 51 whose tip is curled outward is formed in an opening portion of the aerosol container main body 50. A mounting cup 53 fitted with a valve device 52 is clinched on the part. Specifically, the side surface portion 55 continuous below the annular groove portion 54 of the mounting cup 53 is pushed outward by the clinch claws 56 of the clinch machine, thereby abutting against the inner surface wall 57 below the bead portion 51, The mounting cup 53 is firmly clinched in the opening of the aerosol container body.
[0003]
[Problems to be solved by the invention]
However, in such a conventional aerosol can, since the aerosol container body 50 and the mounting cup 53 are firmly fitted, the mounting cup 53 is resistant to the internal pressure received from the inside of the aerosol container body 50. However, there is a drawback that it is difficult to remove the mounting cup 53 from the aerosol container body 50 when the container is discarded after the contents are lost. In particular, removal work was impossible for women and children. For this reason, conventionally, the mounting cup 53 with the valve device 52 attached to the aerosol container body 50 is often discarded just by making a hole in the container body. Further, in the case of a small aerosol container, the valve case is often discarded in a state where the valve case is fitted to the aerosol container body.
[0004]
However, in recent years, as the recycling of aerosol containers has become active among the aerosol industry and consumers, it has been required to separate and dispose of the valve device and mounting cup or valve case from the aerosol container body. At the time of disposal, easy removal from the valve device and mounting cup or valve case and separate collection have been required.
[0005]
The present invention has been made paying attention to such a conventional problem, and can easily separate the mounting cup or valve case to which the valve device is attached from the container body when the container such as the aerosol container is discarded. An object is to provide an aerosol container which can be disposed of separately.
[0006]

[0007]
The second embodiment is a type of aerosol container in which a latching groove is formed in the opening of the aerosol container body and the outer periphery of the side surface of the valve case covering the valve is abutted from the outside and crimped. A curl portion for engaging a separating tool is formed at the tip of the outer periphery of the side surface of the case.
[0008]
In addition, the third embodiment is an aerosol container that can be separated and disposed, wherein a thick portion is formed instead of the curled portion.
[0009]
The fourth embodiment is an aerosol container capable of being disposed of separately, characterized in that a score is formed on the outer periphery of the side surface of the valve case.
[0010]
Furthermore, in the fifth embodiment, the curling portion or thick portion and the thick portion are engaged with the action point of the bottle opener so that the tip of the stem can be pressed by the fulcrum of the bottle opener. It is an aerosol container that can be disposed of separately, characterized by adjusting the positional relationship of the valves.
