         18 . 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;    an opening/closing means for closing or opening the spout path; and    an open-state maintaining means for maintaining the spout path in its open state,    wherein said spout path has a pipe that leads into the sealed can body; a spout that leads to the outside; and a connecting path for connecting the pipe and the spout,    wherein said connecting path is composed of a hollow part of a pipe supporting member for supporting the pipe and a hollow part of a movable member that is inserted into the pipe supporting member,    wherein said opening/closing means is composed of a packing that is a blockage between the hollow part of said pipe supporting member and the hollow part of said movable member, and a pushing member that releases the blockage by pushing down said movable member,    wherein a guard is provided to a caulked projection of said sealed can body in such a manner that said pushing member is enclosed by the guard, one end of said pushing member is connected to the guard, and a lever is provided to the other end of the pushing member,    wherein said open-state maintaining means comprises a bendable plate provided to said guard, and    wherein pressure is released from said sealed can body to outside while maintaining said spout path in its open state by bending said bendable plate to engage the pushing member with the lower part of the bendable plate in a state that said pushing member is pushed down by operating said lever.
