BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid having an aerosol container degassing structure and a degassing method capable of safely and easily degassing an aerosol container.

[0002]

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 a jet hole using a piercing machine has a problem in terms of equipment cost and installation location of the piercing machine. In addition, a method in which a person uses a piercing tool to provide a discharge hole in a container body does not have the above-described problem of cost and the like, but requires work labor and work time,
There were problems such as risk of explosion. Also,
When using the accessory of another member, it must be stored so as not to lose this accessory. In degassing, there is an inconvenience that the nozzle must be continuously pressed with a finger until gas is exhausted.

[0004] In order to solve these problems, the present inventor has obtained the idea that it is preferable to make available the lid of the aerosol container. For this purpose, it is possible to adopt a configuration in which a concave portion and a through-hole for inserting the tip of the nozzle are provided at the center of the upper surface of the lid that normally fits in the front direction. When used as a lid, it may be used by fitting it in the normal direction.When discarding a used aerosol container, by fitting this lid in the opposite direction, the above-mentioned concave portion forms the nozzle forming port. Since the through hole formed in the center of the container presses the nozzle tip, the gas remaining in the container can be discharged from the pressed nozzle through the through hole to the outside of the lid as it is. Become. By adopting such a method, gas can be quickly vented by simply fitting the lid in the opposite direction without requiring a separate member, which is extremely convenient. However, this method can still carry unexpected and unexpected risks. When the lid is inadvertently turned to a person or a device, or when a person stands unexpectedly on the opposite side, exhaust gas may be directly blown to a person or a device. The present invention has been made based on both the above-mentioned conventional technology and the above-mentioned improvement method, and has a lid and a degassing method provided with a degassing structure of an aerosol container which enables safe and quick degassing. It will not be provided.

[0005]

In order to solve the above-mentioned problems, a lid having a gas venting structure according to the present invention is fitted on an aerosol container formed by projecting a nozzle which performs a jetting action in a pressed state on an upper surface. a cylindrical lid, to form a fitted possible fitting portion to the container top by a lid in the opposite direction to the upper outer lid, the aerosol container body portion at the time of the reverse fit in the upper surface of the lid
A through hole that can not be inserted but the tip of the nozzle can be inserted is formed, and a bridge-shaped direction change portion is formed in the inside of the lid of this through hole so as to block the axial direction of the through hole and maintain the opening sideways It is characterized by the following.

[0006] In the above structure, for example,

Since the diameter of the small through-holes may slightly vary depending on the type of aerosol container and the manufacturer, the nozzle can be inserted and pressed at an appropriate position. Any configuration is possible. For example, the small through-hole has a diameter that allows the nozzle to be inserted, and the inserted nozzle stops at an appropriate position, so that the nozzle is maintained in a pressed state in a state where the lid is fitted in the opposite direction, so that the small through-hole is pressed. A plurality of inclined ridges that gradually project from the insertion start end toward the other end can be formed on the inner peripheral surface of the ridge. A direction changing portion can be formed in the inside portion of the small through-hole by, for example, constructing a bar-shaped abutting portion so as to block the axial direction thereof at a slight distance from the small through-hole.

According to the present invention, a cylindrical lid which is fitted to an aerosol container formed by projecting a nozzle which performs a jetting operation in a pressed state at the center of the upper surface is reversed and fitted to the upper surface of the container. With this, the tip of the nozzle is brought into a pressed state, the residual gas in the container is jetted from the pressed portion toward the inside of the lid, and a direction changing portion is provided in the jetting direction so that the jetted gas is not linearly discharged inside the lid. The method is also characterized by a method of degassing the aerosol container so that the gas is discharged into the aerosol container.

According to this, the nozzle of the aerosol container is pressed by fitting the lid fitted on the aerosol container in the opposite direction, and the residual gas is automatically and continuously discharged through the small through hole. be able to. Moreover,
The exhaust gas is directed by a direction change unit provided in the ejection direction.
