Abstract

PURPOSE:To eliminate unsprayed liquid retained in a nozzle, etc., by constituting the structure in such a way that a substitution air passing is closed when spraying is carried out, and the outer atmosphere is supplied to the vessel through the nozzle and a liquid passage. CONSTITUTION:The outer periphery of the spray button 1 and the inner wall of the body 2 are made in a hermetic structure, and the substitution air passage 16 is not connected to the outer atmosphere in this state even by pushing the spray button 1. When the spray button 1 is returned and a negative pressure corresponding to the sprayed amount, is generated in the vessel 10, the upper part of piston and the lower part of the spray button 1 brought in contact with it are individually relaxed so that the outer atmosphere enters the vessel 10 through the nozzle aperture 5, the liquid passage 11 and the substitution air passage 16. At this time, the unsprayed liquid remaining in the nozzle and the liquid passage 11 is sucked and returned into the vessel 10, and the clogging, etc., of the nozzle caused by oxidation, contamination due to mold, and drying is prevented.
