DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol-type jetting container, and more particularly to a degassing cap for an aerosol container for extracting residual gas from a used aerosol container.

[0002]

A container in which an aerosol can is filled with a high-pressure gas and a liquid content and the liquid content is discharged by pushing down a stem has been used conventionally. The above containers are discarded after the contents have been used up, but even if the contents no longer come out, gas may remain in the aerosol can and accidental heating may cause the can to burst. was there.
For this reason, do not place the aerosol can in a place where there is a fire, push down the stem until the gas completely escapes when disposing, or make a hole in the aerosol can with a nail etc. I'm asking. However, even if the stem is pushed down to release gas, it takes time to completely remove the stem, and there is a problem that it is not easy to make a hole.

An object of the present invention is to solve the above-mentioned problems by providing a gas that completely degass the gas after exhausting the contents and pushing down the stem only by fitting the cap. An object of the present invention is to provide an aerosol-type ejection container to which a removal cap is attached.

[0004]

According to the present invention, there is provided an aerosol container provided with a valve member as a gas release cap of an aerosol container, an ejection member, and a cover member of the valve member. An aerosol-type ejection container having a cap fitted to a cover member, wherein the cap is provided with a reversing locking plate, and the reversing locking plate is turned over when the cap is fitted. Is adapted to engage with the ejection member and push down the stem.

[0005] As an ejection member of the aerosol type ejection container, a discharge member for foamed contents or a sprayer for contents is employed.

[0006]

Next, a first embodiment of the present invention will be described with reference to the drawings. The present embodiment relates to an aerosol-type ejection container that discharges foam-like contents. In FIGS. 1 and 2, A denotes an aerosol container, B denotes a cover member of a valve member, and C denotes a cap.

The aerosol container A includes an aerosol can body 1
And a valve member 2. The valve member 2 includes a stem 3 which is urged upward by a spring to open and close the valve. In the aerosol container A, cosmetics are enclosed as contents together with the foamed high-pressure gas.

The cover member B comprises a cover member 4 and a discharge member 6 of a foam-like content having a discharge pipe 5 erected on the upper surface. The cover body 4 includes a fitting tube 7 fitted on the outer periphery of the valve member 2 and a cap holding tube 8 outside the fitting tube 7.
And a jacket 9 for covering the aerosol container A, and a top wall 10 continuously provided between upper end edges of the fitting tube 7 and the cap holding tube 8.

[0009] A step is provided on the inner periphery of the fitting cylinder 7, and a bulging ring 11 is provided on the inner periphery of the lower end. A bulging ring 12 is provided at an intermediate portion on the outer periphery of the cap holding cylinder 8.

The discharge member 6 has a top wall 13 and a side wall 14, and a stem engaging cylinder 15 that engages with the stem 3 is vertically provided on a lower surface at the center of the top wall 13. The discharge pipe 5
It is provided at a position eccentric to the stem engaging cylinder 15, and the inner hole 16 of the stem engaging cylinder 15 communicates with the inner hole of the discharge pipe 5 to form a flow path for the contents. Discharge pipe 5 at lower end of side wall 14
Hinge portion 1 connected to the top wall 10
7 are formed.

As shown in FIG. 3, the cap C is
0 and a side wall 21, and cutting grooves 22, 23 of a predetermined width are vertically formed in parallel at an intermediate portion of the side wall 21 over a predetermined angle range. Recesses 24a, b are provided between both ends of the cutting grooves 22, 23, and the cutting grooves 22, 2 are provided.
3 and a portion surrounded by the concave stripes 24a and 24b form an inversion locking plate 25. A bulging ring 26 protrudes from the lower end periphery of the side wall 21 and engages with the bulging ring 12 of the cap holding cylinder 8 so that the cap C is fitted and held at a fixed position.

Next, the mode of use and the effects of the container will be described. In using the container, when the cap C is removed and the discharge member 6 is pressed, the stem engaging cylinder 15 pushes down the stem 3, and the contents are foamed and discharged from the discharge pipe 5.

When the contents are completely discharged, the cap C
When the reverse locking plate 25 is pushed inward, as shown in FIGS. 4 and 5, the reverse locking plate 25 is inverted around the concave ridges 24a and 24b, and the state is maintained. When the cap C is fitted on the cover member B, the inversion locking plate 25 presses the discharge member 6, the stem 3 is pressed down, the valve is opened, and the remaining gas is discharged.

Next, a second embodiment will be described with reference to FIGS.
This will be described with reference to FIG. This embodiment relates to an aerosol-type ejection container that ejects contents. In FIG. 6, Aa is an aerosol container, Ba is a cover member of a valve member, Ca is a cap, and D is a nebulizer. The aerosol container Aa includes an aerosol can body 1a and a valve member 2a, and the valve member 2a includes a stem 3a that is urged upward by a spring to open and close the valve.

The cover member Ba has a fitting tube 7a, a cap holding tube 8a, and a jacket 9a, and is mounted on the valve member 2a. A swelling ring 12a is provided on the outer periphery of the cap holding cylinder 8a.

The sprayer D has a spray nozzle 31 provided with a fine hole 30, a stem insertion hole 32, and an inner hole 33 connecting the two. In the sprayer D, the stem insertion hole 32 has the stem 3a.
Is directly attached to the aerosol container Aa.

As shown in FIG. 7, the cap Ca is composed of a top wall 40 and a side wall 41. Cutting grooves 42, 43 having a predetermined width are vertically arranged in parallel at an intermediate portion of the side wall 41 in a predetermined angle range. It is drilled over. Between the two ends of the cutting grooves 42, 43, concave ridges 44a, b are provided, and the cutting grooves 42, 43 are provided.
An inverted locking plate 45 is formed by the portion surrounded by 43 and the concave stripes 44a and 44b. It is preferable to provide the inversion locking plate 45 at two locations so as to be located symmetrically, but only one may be provided. A swelling ring 46 protrudes from the lower end periphery of the side wall 41, and the swelling ring 12 of the cap holding cylinder 8a.
a so that the cap Ca is fitted and held at a fixed position.

Next, the mode of use and operation and effect of the sprayer of this embodiment will be described. In using the container, when the cap Ca is removed and the sprayer D is pressed, the stem insertion hole 32 pushes down the stem 3a, and the contents are sprayed from the spray nozzle 31 through the inner hole 33 in the sprayer D.

When the contents are completely taken out, as shown in FIG. 8, when both of the reversing locking plates 45 of the cap Ca are pushed inward, the reversing locking plates 45 are reversed around the grooves 44a and 44b. That state is maintained. The cap Ca,
When fitted to the cover member Ba, the reverse locking plate 45 pushes down the sprayer D, the valve is opened, and the remaining gas is discharged.

[0020]

Since the present invention is configured as described above, it has the following effects. By providing the cap with a reversing locking plate, after using the contents, the reversing locking plate is pushed in and flipped, and the cap is simply fitted on the cover member,
The residual gas in the aerosol can can be completely removed, and the degassing after use of the container can be easily performed.
