PROBLEM TO BE SOLVED: To provide a spray pressurization structure and a spray that enable the prevention of swelling the sealing member of a piston-cylinder assembly due to an organic solvent liquid and steam even when sprayed with this liquid, long-term spray function maintenance, easy recovery of the residual liquid, and repetitive use and easy cleaning of the spray.SOLUTION: A spray pressurization structure having a trigger structure with a nozzle structure attached to the opening of a spray liquid container and a pressurization structure comprises a piston-cylinder assembly that compresses outer air under the reciprocating slide of a piston involving a sealing member in the inner hole of a cylinder inserted into the opening with one end at the top to extrude the outer air from the one end, a plurality of check valves provided independently of one another in series at the one end, and a sheath member that includes an attachment part where the cylinder outer peripheral surface is integrally formed with the sheath part covering the valve to be detachable in sealing contact with the opening and the other end of the cylinder and regulates a passage for guiding the compressed gas from the valve at the most distal end to an inner space part of the container adjacent to the attachment part between the sheath part and the outer peripheral surface.SELECTED DRAWING: Figure 1 |
