BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of using a cap of an ejection valve having a projection and a cap of an ejection valve having a projection and a method of preventing explosion by a cap of an ejection valve having a projection. By using the protrusion of the cap of the ejection valve having the discharge valve, the pressurized fluid such as residual gas remaining in the container is discharged to the outside in order to discharge the residual gas after use of the injection container having the ejection valve to the outside. For preventing explosion of an injection container by means of a cap of a jet valve having a projection capable of preventing the explosion of an already used injection container, and a jet valve cap having a projection for preventing the explosion of the injection container and a jet valve having the projection How to use the cap.

[0002]

2. Description of the Related Art Conventionally, an opening portion is formed at a suitable place on the surface of an injection container having a jet valve after use by a perforating tool for cooking or the like, and is communicated with the atmosphere through the opening portion.
It has been practiced to discharge a pressurized fluid such as residual gas remaining in an injection container having an injection valve to the outside to prevent the used injection container from exploding. However, even if the punching tool for cooking has a structure suitable for punching a can of beverage, etc., after using a spray container such as an aerosol spray container, the residual gas in the spray container is discharged to the outside. It has been attempted to prevent the explosion of the used injection container by releasing the pressurized fluid such as residual gas remaining in the injection container to the outside to release it, but it remains in the injection container. Because it is not a dedicated device for releasing pressurized fluid such as residual gas to the outside, even if it is possible to make a hole, due to the structural defect of the perforation tool for cooking itself, aerosol ejection It is a difficult technique to perforate the surface of an injection container such as a container, and in particular, for a general person who is not accustomed to perforating the surface of the injection container, the perforation of the surface of the injection container itself It was difficult.

[0003]

Therefore, conventionally, it is necessary to prevent the used injection container from exploding by means of a device suitable for discharging the residual gas in the used injection container to the outside. For the purpose of one. In addition, it is usually used as a closing cap for an injection container such as an aerosol injection container, and a projection provided at an appropriate position on the closing cap of the injection container pushes down the on-off valve part of the injection container to close it. To prevent the explosion of the used injection container by releasing the pressurized fluid such as residual gas remaining in the used injection container to the outside by making it possible to work from the open state to the open state very easily. And the second purpose of. In addition, the projection of the ejection valve cap having the projection is applied to the upper portion of the on-off valve of the injection container, the portion of the ejection valve cap is grasped with a finger, and the projection at the tip of the ejection valve is pushed down to remove the closed state. It is a third object of the present invention that it can be easily opened. Also, when using a spray container such as an aerosol spray container, the push button type spray head is operated to spray out from the spray port, but the spray liquid supply that supports the push button spray head with that spray port. Since the pipe is extremely thin, when the injection liquid supply pipe that supports the button type injection head is attached to the injection container main body when carrying out the injection container such as the aerosol injection container, which is the product, from the place of production to the place of consumption, until now, The injection liquid supply pipe supporting the push button type injection head was often broken or disengaged. Therefore, when carrying an injection container, such as an aerosol injection container, from the production site to the consumption site, the injection container body and the injection liquid supply pipe that supports the push-button injection head are carried separately and are pushed when using the injection container. The injection liquid supply pipe that supports the button-type injection head and the injection container body are integrated so that they can be used.However, when transporting from the production site to the consumption site, the injection valve is used to protect the injection valve. A cap is put on the top surface of the valve, and the cap surely protects the ejection valve portion.When the injection container is used, the cap is removed and the injection liquid supply pipe that supports the injection container body and the push button type injection head is used. When the injection container is used, and the injection container is completely used, the ejection valve can be opened by the protruding portion provided on the cap, which is simple but practical. The fourth object of the present invention to provide an explosion prevention method according to the cap of the ejection valve to have a method and projections used in the cap of the ejection valve having a cap and the projection of the ejection valve with that projection.

[0004]

According to the present invention, a jet valve is inserted into and fixed to a cylindrical inside of a central portion of a mountain cap,
A cap for an ejection valve having a projection, characterized in that a projection for lowering and opening an appropriate position of the ejection valve when the ejection valve is closed from outside the ejection valve is provided on the cap of the ejection valve.
