An aerosol container consists of a pressure-resistant container and an aerosol valve attached to the opening of the container, and a propellant such as a stock solution containing active ingredients as contents in the container and a combustible liquefied gas such as liquefied petroleum gas or dimethyl ether. In addition, an aerosol product is obtained by mounting an injection member.
The aerosol product has a pressure of about 0.2 to 0.6 MPa at room temperature, and when the valve is opened by an injection operation such as pushing down the injection member, the aerosol composition inside the container is injected outside.

  Currently, aerosol products that are no longer needed are collected as non-combustible garbage by consumers with no aerosol composition remaining in the container (empty state). There is an accident that causes a fire because the aerosol product is compressed in the collection vehicle and the container ruptures. Aerosol products are provided with a cautionary note or label to dispose of them after they have been used up, but they may still be disposed of with the aerosol composition remaining inside the container, which can easily cause a fire accident. ing.

  However, it is troublesome for the consumer to perform the injection operation until the inside of the container is emptied independently of the purpose of use. In particular, many aerosol products perform the injection operation by pushing down the push button of the injection member with a finger. However, it is necessary to continue to press the injection member until the injection is completed, which is troublesome.

Japanese Patent Application Laid-Open No. 2004-228688 discloses a technique in which a push button is removed, the push button is inverted and mounted inside a cap, and the cap is mounted on a cover member to open the valve.

  There is also known a discharge mechanism in which a discharge tool is attached while an injection member such as a push button is attached, and the valve is always open. In Patent Document 5, a protrusion for pressing the push button on the top surface of the cap and an engagement protrusion for mounting the cap on the cover member are provided, and the cap is inverted and the upper surface of the cap is attached to the cover member. Thus, it is disclosed that the push button is depressed and the valve is always opened. Further, Patent Documents 6 and 7 disclose that a part of the top surface of the cap is bent or attached to the container in a pressed down state, whereby the push button is pressed down to always open the valve.

  Furthermore, a discharge mechanism is known in which a push button and a cover member or a cap are used to keep the valve open at all times. Patent Document 8 discloses a structure in which a rotating protrusion attached to a push button is raised upward and a cap is attached to a container so that the rotating protrusion comes into contact with the top surface of the cap and the push button is pushed down. Yes. Patent Document 9 discloses a device that rotates a push button to engage a protrusion of the push button with a cover member, and holds the push button in a depressed position. Japanese Patent Application Laid-Open No. H10-228561 discloses a device in which the lever at the rear part of the push button is picked and turned in a state where the push button is depressed, and the lever is engaged with the groove of the cover member. Japanese Patent Application Laid-Open No. H11-228561 discloses a mechanism in which a rotary lever is engaged with a cover member by rotating a rotary lever at the rear of the push button after the push button is pressed down.

The bead part 11d is formed in the upper end opening of the metal eyepiece. In addition, as the pressure vessel 11, for example, a metal plate made of aluminum, tin or the like is formed into a bottomed cylindrical shape by impact processing or drawing processing, and further a shoulder portion and a bead portion are formed by necking processing or curling processing. May be. Further, other materials having pressure resistance such as synthetic resin and pressure glass may be used.

  The valve 12 is also a conventionally known one, and includes a mounting cup 19 that is fixed to the bead portion 11d of the pressure vessel 11, a cylindrical housing 20 that is held in the center of the mounting cup, and is movable up and down within the housing. A stem 21 that is housed and is constantly biased upward by a spring, and a stem rubber that covers the stem hole of the stem and seals the inside of the aerosol container in a state where the stem 21 is biased upward by the repulsive force of the spring (see FIG. And a dip tube 22 extending from the lower end of the housing to the bottom of the pressure vessel main body.

  The injection member 14 includes a cover member 24 attached to the head of the aerosol container (a curled portion of the mounting cup) and a push button 25 attached to the upper portion of the stem. As shown in FIGS. 2a to 2d, 3a, and 3b, the cover member 24 includes a mounting portion 27 for mounting on a curled portion of the mounting cup, and a pair of side wall portions 24a that cover both side surfaces of the push button 25. It has. The side wall portion 24a extends upward from the mounting portion 27 so as to cover both side surfaces of the push button 25, and the top surface of the side wall portion 24a is located higher than the top surface 25a of the push button. The side wall 24a can prevent malfunctions such as accidental injection of the aerosol composition by hitting the push button 25 when not in use, and it can be prevented by a finger during normal use and a coin during discharge operation. Can be used to easily push down the push button 25 vertically downward, and the valve can be opened reliably. As shown in FIG. 2b, a slit 30 extending in the horizontal direction is formed at the rear part of the side wall part 24a. The width of the slit 30 is 1 to 3 mm, preferably 1 to 2.5 mm, and the lower surface 30a of the slit 30 is located below the top surface 25a of the push button with the push button 25 not being pushed down. .

The injection hole side (front surface) of the cover member 24 is recessed so that the injection hole 36 is exposed even when the push button 25 is pushed down, and the rear side of the cover member 24 can be pushed down with the finger on the head of the push button. It is so depressed.
The push button 25 includes a stem mounting portion 35 for mounting on the stem 21, an injection hole 36 for injecting the aerosol composition to the outside (atmosphere), and a passage 37 connecting the stem mounting portion 35 and the injection hole 36. (See FIG. 3a).

  The coin 16 is a thin disk as shown by an imaginary line in FIG. 2d, and has a diameter of 20 to 30 mm and a thickness of 1 to 3 mm. Coins, medals and the like can be used. The coin is preferably made of a metal such as copper, zinc, tin, nickel, aluminum and a mixture (alloy) thereof, and has higher hardness than a cover member made of synthetic resin such as polyacetal, polyamide, polyolefin, polyester, Easy to insert coins and easy to pull out coins. Further, it is preferable that the thickness of the coin 16 is slightly larger than the width of the slit 30. Thus, when the coin 16 is inserted into the slit 30, the coin 16 is difficult to be removed due to friction between the coin and the slit. Further, since the coin 16 used in daily life can be used as the coin 16, even if the attached coin is lost, the coins can be discharged using these coins. In this embodiment, the coin 16 is provided in the aerosol product. However, since everyday items such as coins can be used, the coin 16 may not be provided as an accessory of the aerosol product.

When the top surface (upper surface) 25a of the push button is pushed down with a finger, the stem is pushed down together with the push button, and the stem hole of the valve. Is released. At this time, the inside of the aerosol container communicates with the atmosphere, and the aerosol composition inside the aerosol container is supplied to the inside of the housing through the dip tube, and further injected into the atmosphere from the injection hole via the stem hole and the push button passage. Is done.

  Further, when the aerosol product is no longer needed and is to be discarded, the top surface (upper surface) 25a of the push button is pushed down with a finger or the like, and the coin 16 is inserted into the slit 30 in this state. At this time, since the top surface (upper surface) 25a of the push button is in contact with the lower surface of the coin 16, the push button 25 does not rise even when the finger is released and is maintained at the position where the aerosol valve is opened (FIG. 3b). reference). While the coin 16 is inserted, the aerosol product is maintained in an open state communicating with the atmosphere, so that the entire amount of the aerosol composition remaining inside the aerosol container can be discharged. In addition, since the repulsive force of the spring is applied to the coin 16 inserted into the slit 30 upward in the axial direction of the container via the push button 25, the radial frictional force between the coin 16 and the slit 30 is further increased. The coin 16 is difficult to come off. When the discharge from the aerosol product stops, the coin 16 can be collected by pulling out the coin 16. Note that it is more preferable to discard the coins 16 with the coins 16 attached since the person collecting the aerosol products can recognize that the aerosol products have been discharged. In this case, it is preferable to use a coin made of the same material as that of the pressure vessel because it is easy to recycle.
