Description

  The present invention relates to an aerosol container injection device that is attached to an aerosol container and injects the contents ejected from a valve stem of the aerosol container to the outside.

There are known aerosol products, such as deodorants and insecticides, that inject the contents of an aerosol container to the outside from an injection port.
Aerosol products are generally installed in an aerosol container filled with a liquid or powdered content of combustible gas compressed as a propellant, and the contents are ejected from the valve stem attached to the valve stem of this aerosol container. And an injection device for injecting it to the outside (see FIG. 1 of Patent Document 1).

  By the way, the aerosol container used for the aerosol product is a metal product, the injection device is a synthetic resin product, and the materials are different from each other. Therefore, when the used aerosol product is discarded, it is injected from the aerosol container. It is desirable to remove the device and dispose of it separately.

  Patent Document 2 discloses an injection device that can be removed from an aerosol container with a slight operating force when an aerosol product is discarded. When separating from the aerosol container for separation and disposal, the pressing portion is caused to move forward with the hinge portion as the center of rotation so that the pressing portion is detached from the valve stem. Next, when the pressing portion is pulled away from the cylindrical injection device main body, the thin portion breaks, and the portion sandwiched between the pair of thin portions of the injection device main body is torn with a slight operating force. The pressing portion is separated from the injection device main body.

  Due to the separation of the pressing part, the injection device main body part fitted to the mountain cup part of the aerosol container is in a form in which a part in the circumferential direction is cut off, and the cutting part is urged in the direction to push it left and right. By doing so, the injection device main body can be easily detached from the mountain cup.

  In general, aerosol containers often contain flammable gas for releasing contents even after the liquid or powdery contents are used up. Since the flammable gas is a gas that may ignite and explode if there is fire, an unexpected situation may occur if the aerosol container is discarded with the flammable gas remaining. For this reason, the injection apparatus provided with the residual gas discharge function is proposed so that the aerosol container can be discarded after all the residual gas is discharged.

  Patent Document 3 discloses a residual gas discharge mechanism of a type in which an aerosol button is attached after removing an aerosol button from a valve stem. In this type of residual gas discharge mechanism, the aerosol button must first be removed from the valve stem. Conventionally, the aerosol button has been removed by using a tool such as pliers or pinching with a finger.

  However, it is difficult to adopt the configuration of Patent Document 2 in order to easily remove the injection device as shown in Patent Document 1 from the aerosol container. The injection device described in Patent Document 1 is of a type in which the skirt portion of the injection device as shown in Patent Document 2, that is, the annular portion for container connection covers the outer periphery of the mountain cup, only by being fitted to the aerosol valve. It is not.

  Therefore, it is necessary to devise a spray device that is simply inserted into the aerosol valve as in Patent Document 1 so that it can be easily removed from the aerosol container. If the spray device is difficult to remove from the aerosol container, the user's willingness to sort will fluctuate, making it difficult for thorough sorting and disposal.

  Furthermore, in the type of Patent Document 3, it is difficult to remove a tool because it is necessary to prepare a tool, or when a person pulls up with a finger, the aerosol button and the finger slide.

  The present invention has been made in order to solve the above-described problems, and in an aerosol container injection device that is fitted into a valve stem of an aerosol container and is mounted inside a mountain cup, the valve stem of the aerosol container and the aerosol container An object of the present invention is to make it possible to easily release the insertion state with the injection device.
