Spray can, and spray can pressure releasing structure

Abstract

The present invention relates to a spray can and a pressure releasing structure thereof, in which the pressure in the spray can can be easily and quickly released. A spray can 200 comprises a sealed can body 14 for holding a compressed fluid such as cosmetics, paints, or propane gas, a spout path 16 for leading the fluid in the sealed can body 14 to the outside, an opening/closing means 18 for opening and closing the spout path 16 , and an open-state maintaining means 202 for maintaining the spout path 16 in its open state.

1 . A spray can comprising: 
 a sealed can body for holding a compressed fluid;    a spout path for leading the fluid in the sealed can body to the outside;    an opening/closing means for closing or opening the spout path; and    a pressure releasing structure for allowing pressure to be released from the sealed can body to the outside.    
     
     
         2 . The spray can according to  claim 1 , wherein said pressure releasing structure is an open-state maintaining means for maintaining the spout path in its open state.  
     
     
         3 . The spray can according to  claim 1 , wherein said pressure releasing structure is a breaking means for breaking the spray can.  
     
     
         4 . The spray can according to  claim 3 , wherein said breaking means is a means for breaking the spout path.  
     
     
         5 . The spray can according to  claim 4 , wherein said spout path comprises: 
 a pipe leading to the fluid in the sealed can body;    a spout leading to the outside of the sealed can body; and    a connecting path for connecting the pipe and the spout,    wherein said breaking means is a means for separating the connecting path.    
     
     
         6 . The spray can according to  claim 5 , wherein said breaking means is a means for breaking the spout path by spring force applied to the spout path by pushing down a pushing member and wherein the breaking means has a restricting means for restricting the distance that the pushing member is pushed down.  
     
     
         7 . The spray can according to  claim 6 , wherein said opening/closing means is a means for opening the spout path by pushing down the pushing member and the pushing member of the opening/closing means is the pushing member of the breaking means.  
     
     
         8 . The spray can according to  claim 3 , wherein said breaking means is a means for breaking the sealed can body.  
     
     
         9 . The spray can according to  claim 1 , wherein said pressure releasing structure is a release path forming means for releasing pressure from the sealed can body to the outside.  
     
     
         10 . The spray can according to  claim 9 , wherein said opening/closing means is a means for opening the spout path by pushing down a pushing member and is capable of forming a release path that releases the compressed fluid to the outside by pushing down the pushing member.  
     
     
         11 . A pressure releasing structure, comprising: 
 a sealed can body for holding a compressed fluid;    a spout path for leading the fluid in the sealed can body to the outside; and    an opening/closing means for closing or opening the spout path,    wherein said pressure releasing structure allows pressure to be released from the sealed can body to the outside.    
     
     
         12 . The pressure releasing structure according to  claim 11 , wherein said pressure releasing structure is an open-state maintaining means for maintaining the spout path in its open state.  
     
     
         13 . The pressure releasing structure according to  claim 11 , wherein said pressure releasing structure is a means for breaking the sealed can.  
     
     
         14 . The pressure releasing structure according to  claim 13 , wherein said pressure releasing structure is a means for breaking the spout path.  
     
     
         15 . The pressure releasing structure according to  claim 13 , wherein said pressure releasing structure is a means for breaking the sealed can body.  
     
     
         16 . The pressure releasing structure according to  claim 11 , wherein said pressure releasing structure is a release path forming means for releasing pressure from the sealed can body to the outside.  
     
     
         17 . The pressure releasing structure according to  claim 11 , wherein said opening/closing means has a locking means for locking the spout path so that the spout path is not opened.
