Description

  The present invention relates to improvements in aerosol devices.

  In general, an aerosol device ejects gas or liquid in an aerosol container by pressing an injection button. In addition, aerosol containers that contain paints, insecticides, cosmetics, etc. contain combustibles such as main agents (contents other than propellants consisting of liquids and solids) and propellants (liquefied petroleum gas, dimethyl ether, isopentane, etc.) Even when the main agent is exhausted and the spraying is finished, a small amount of propellant remains in the container.

  By the way, when disposing of such an aerosol device, in consideration of safety at the time of dust collection or compression processing, the user keeps pushing the injection button until no sound is generated or a hole is formed in the aerosol container. The propellant remaining in the used aerosol container must be discharged by the operation of opening the container. However, the operation of manually discharging the remaining propellant is very troublesome because the spray button of the aerosol container must be pressed for a long time. Further, in order to keep pressing the spray button for a long time, it is often necessary to change the aerosol container and continue to spray the contents remaining in the container, and the contents cannot be reliably discharged. Furthermore, since these operations are time-consuming, there is a problem that the contents remaining in the aerosol container are discarded without being completely discharged.

  In view of this, a residue discharge mechanism for easily and safely discharging the entire content (residue) remaining in such a used aerosol container has been proposed (see Patent Document 1). Specifically, the aerosol container residue discharging mechanism described in Patent Document 1 is roughly configured by a cylindrical injection button that is attached to the stem of the aerosol container and a shoulder cover that is fitted to the top of the aerosol container. ing. The injection button has a projection, and the shoulder cover has a cylindrical central hole into which the injection button is inserted. The projection of the injection button is slidable on the annular peripheral wall forming the central hole. A deep cut portion and a shallow cut portion to be inserted are provided. Furthermore, the deep cutouts and the shallow cutouts are alternately formed at equal intervals in the circumferential direction of the central hole.

  In the method of using the aerosol container residue discharging mechanism, in a normal use, the protrusion of the injection button is fitted into the deep cutout, and the movement distance of the injection button is set to be long. The stem can be opened and closed by pressing the injection button and releasing the pressure. On the other hand, when discharging the contents remaining in the aerosol container, the position of the injection button is changed to insert the protrusion into the shallow notch, thereby restricting the movement of the injection button. Thereby, since a stem is always pressed by the injection button, an open state is maintained. In this state, the residue in the aerosol container is released.

  In addition, in the one-touch cap type aerosol device in which the spray button and the cover cap of the aerosol container are integrated, as a method of discharging the contents remaining in the aerosol container after use, the spray button and the cover cap are integrated. After removing from the aerosol container and taking means for discharging the residual contents, a method of reattaching them to the aerosol container (see, for example, Patent Documents 1 to 4), only a cover cap or a spray button There is a method (for example, refer to Patent Documents 5 and 6, etc.) in which these are removed from the aerosol container and measures are taken to discharge residual contents, and then these are reattached to the aerosol container.

  Among these, in the method of removing the spray button and the cover cap integrally from the aerosol container, the operation of discharging the residual contents can be facilitated and the operation procedure can be reduced. However, when removing the injection button integrally with the cover cap, the stem may be damaged by applying an external force in a direction different from the direction in which the injection button is pressed to the stem. In this case, if the stem is damaged, it becomes impossible to appropriately perform the operation of discharging the residual contents.

On the other hand, in the method of removing only the cover cap or the spray button from the aerosol container, the possibility of breakage of the stem described above is reduced, but it is necessary to remove the spray button and the cover cap separately from the aerosol container. There are disadvantages such as complicated operations for discharging the wastewater and increased operation procedures. In addition, after discharging the residual contents, it is necessary to separate and discard the plastic cover cap and spray button from the aerosol container. In this case, it is necessary to remove the spray button and cover cap from the aerosol container separately. Therefore, there is a disadvantage that workability is deteriorated particularly when the injection button is small.
