Gushing.

Next, when the spray can 200 has been used and the spray can 200 is to be discarded, the pressing member 38 is rotated 90 °, the pressing member is pressed, and the moving member 32 is moved downward. In this state, the protrusion 204 is engaged under the claw 206 as shown in FIG. As shown in FIG. 2 (b), by engaging the convex portion 204 with the claw portion 206 below the packing portion 36, the packing portion 36 is broken and the hollow portion 30 and the hollow portion 34 communicate with each other. The state is maintained. By maintaining the state in which the hollow portion 30 and the hollow portion 34 communicate with each other, even if the hand is released from the pressing member 38 and the cosmetic product is left alone, the cosmetic can remove the hollow portions 30 and 34 from the pipe 22. As a result, the pressure inside the sealed can 14 is automatically released.

By removing the cosmetics from the sealed can 14 in this manner, the pressure in the sealed can 14 is reduced to be substantially equal to the atmospheric pressure. The spray can 200 is discarded when the pressure is substantially equal to the atmospheric pressure.

As mentioned above, although one Embodiment of this invention was described, the spray can of this invention can be implemented also in another form.

For example, the spray can of the present invention may be a spray can 210 shown in FIG. The spray can 210 is provided with a sealed can body 14, an ejection path 16, opening / closing means 18, and crushing means 2 12 for crushing a part of the ejection path 16. The crushing means 2 1 2 functions as a pressure relief structure for the spray can. The crushing means 2 12 is constituted by the moving member 32, and is configured to separate and crush the pipe supporting member 28 by the moving member 32 by pressing down the moving member 32 deeply. A notch 42 having a V-shaped cross section is provided around the periphery of the vibe holding member 28 for easy separation. In addition, a ring 2 16 having an engagement recess 2 14 is provided at the top of the sealed can 14.
