2. Description of the Related Art Conventionally, in order to release gas from an aerosol container, a piercing hole is pierced in a container body of the aerosol container by using a piercing machine or by a person using a piercing tool such as a nail or a drill. In general, a method of ejecting gas from the ejection holes to release gas has been used. Further, another member for pressing the nozzle of the aerosol container to eject gas has been provided as an accessory.

[0003] However, the method of piercing the jet holes using a piercing machine has problems in terms of equipment cost and installation location of the piercing machine. In addition, the method in which a person uses a piercing device to form a discharge hole in the container body does not have the above-mentioned cost and other problems, but requires work labor and time, and involves the risk of explosion and the like. There was a problem. In addition, when using an accessory of another member, it must be stored so as not to lose the accessory, and there is an inconvenience that the gas cannot be released when the separate member is lost when degassing is required. In addition, when degassing, there is an inconvenience in that the nozzle must be continuously pressed with a finger until gas is exhausted.

Therefore, there has been disclosed an aerosol container degassing device which can be easily mounted on an aerosol container and can be maintained in a state in which the injection nozzle of the aerosol container is pressed down simply by mounting (Japanese Utility Model Laid-Open No. 6-69600, Japanese Unexamined Patent Application Publication No. Hei 6-69600). 8
-324661).

For example, in JP-A-8-324661,
As shown in FIG. 9, a concave portion is formed in the upper surface for receiving the nozzle forming opening formed in the upper portion of the aerosol container, and a fitting portion that engages with the peripheral portion of the nozzle forming opening at the peripheral portion of the concave portion. A gas venting tool for an aerosol container is disclosed in which a through hole is formed in which a nozzle tip is inserted into a concave portion and pressed.

[0006]

However, the above-mentioned degassing device has a so-called male valve type aerosol in which an injection nozzle 55 is erected on the upper surface of a container as shown by a two-dot chain line in FIG. Even if the container 50 can be easily degassed, the so-called female valve type 100 in which the injection nozzle is immersed in the nozzle hole 102 as shown in FIG. 1 cannot be degassed. .

Accordingly, the present invention is directed to a female valve type aerosol container in which the injection nozzle is immersed in a nozzle hole, even if the injection nozzle is provided on the upper surface of the container. Even in this case, it is desirable to provide a degassing structure of an aerosol container and a container connector that can easily perform degassing.
