Description

  The present invention relates to a pressure relief structure for a spray can that is compressed and filled with cosmetics, paint, propane gas, or the like.

  Conventionally, cosmetics and other fluids are filled in spray cans and sold. FIG. 36 shows a cosmetic spray can 101 as an example of the spray can. The spray can 101 includes a sealed can body 103 into which cosmetics (fluid) 102 is compressed, a jetting path 104 that guides the cosmetics 102 to the outside, and an opening / closing means 105 that closes or opens the jetting path 104. . As shown in FIG. 37, the ejection path 104 includes a pipe 106 that communicates with the cosmetic product 102 in the sealed can body 103, a spout 107 that communicates with the outside, and a connection path 108 that couples the pipe 106 and the spout 107. ing. The connection path 108 includes a hollow portion 110 of the pipe support member 109 that supports the pipe 106 and a hollow portion 112 of the moving member 111 inserted into the pipe support member 109. The opening / closing means 105 includes a packing 113 that closes the connecting portion between the hollow portion 110 and the hollow portion 112, and a pressing member 114 that pushes down the moving member 111 to open the closing by the packing 113. While the spray can 101 closes and seals the ejection path 104 with the packing 113, when in use, as shown in FIG. 38, the pressing member 114 is pushed down with a finger 115 to deform the packing 113, The cosmetic 102 can be ejected to the outside by opening.

  When such a spray can 101 is discarded, in order to prevent the remaining gas from exploding somewhat, the pressing member 114 is pushed down with a finger 115 to eject almost all of the cosmetic 102, thereby closing the sealed can 103. The internal pressure was released to make it almost the same as the external pressure. However, it took time to release the pressure in this way. Further, the pressure in the sealed can body 103 may be released by opening a hole in the sealed can body 103. However, in this case, it is necessary to perform a difficult operation using a tool, and a cost is required when using a dedicated device.

By the communication between the hollow portion 30 and the hollow portion 34, the cosmetic is ejected from the jet port 24 through the hollow portions 30 and 34 from the pipe 22 due to the pressure in the sealed can body 14.

  Next, when the spray can 200 becomes used and the spray can 200 is discarded, the pressing member 38 is rotated by 90 °, the pressing member is pressed, and the moving member 32 is moved downward in FIG. As shown to a), the convex part 204 is engaged under the nail | claw part 206. FIG. By engaging the convex portion 204 under the claw portion 206, the packing 36 is deformed and the state where the hollow portion 30 and the hollow portion 34 are communicated is maintained as shown in FIG. By maintaining the state in which the hollow portion 30 and the hollow portion 34 communicate with each other, the cosmetics can be passed from the pipe 22 through the hollow portions 30 and 34 from the spout 24 even when the pressing member 38 is left unattended. As the spray continues, the pressure in the sealed can 14 is automatically released.

  By removing the cosmetic from the sealed can body 14 in this way, the pressure in the sealed can body 14 is reduced to be approximately the same as the atmospheric pressure. The spray can 200 is disposed of in a state where 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 with another form.

  For example, the spray can 210 shown in FIG. 3 may be used as the spray can of the present invention. The spray can 210 includes a sealed can body 14, an ejection path 16, an opening / closing means 18, and a crushing means 212 that crushes a part of the ejection path 16. The crushing means 212 functions as a spray can pressure release structure.
