Abstract

A spray unit which installed airtight to the jaw opening part of a container (1) for spraying liquid substance contained in the container (1), comprising a cylinder (11) having a large diameter air cylinder (12) and a small diameter liquid cylinder (13), a large diameter piston (25), a stem (22) having a check valve (38), and a push-down head (24) having a spray nozzle hole (23), wherein a liquid flow path (34) and an air spraying path (31) are merged at the spray nozzle hole (23) through a small clearance (32), a small flow path (55) always providing communication between the container (1) and the liquid cylinder (13) is provided in at least one of a valve seat (53) and a valve disc (51) installed on the upper peripheral surface of a valve hole (42) of the liquid cylinder (13) which constitutes a flow control valve (41), and the crosssectional area of the small flow path (55) is set smaller than each of the opening areas of the valve hole (42) and the valve hole of the check valve (38) so as to eliminate the delay of injection of the liquid.
