SPOUT UNIT FOR CONTENT DISCHARGE PORT SHUT-OFF, CONTENT DISCHARGE PORT SHUT-OFF MECHANISM TO WHICH THE SPOUT UNIT IS ASSEMBLED, AND PUMP TYPE PRODUCT AND AEROSOL TYPE PRODUCT USING THE CONTENT DISCHARGE PORT SHUT-OFF MECHANISM

摘要

PROBLEM TO BE SOLVED: To achieve simplified and efficient assembly work in fabricating a shut-off mechanism of a pump type product or an aerosol type product, or secure management of each member in an assembly process.SOLUTION: Out of a shut-off mechanism, four constituent elements in total which are a stem holder 2, a spout 3, a shut-off drive section 6 and a coil spring 7 excluding an actuator cap 9, a projected nozzle 8 and a movable valve 5 are integrated into a unit structure without being separated from each other. For making them become the unit structure, a valve member 4 for shut-off actin of a content discharge port 8a is divided into the movable valve 5 which is not integrated into a unit and the shut-off drive section 6 which is integrated into a unit. To form the shut-off mechanism before attaching to a stem 1, the movable valve 5 and the projected nozzle 8 are assembled to the unit from a circular opening portion 9b after the unit is assembled from a lower opening portion 9g of the actuator cap 9.
