RECIPROCATING PUMP TYPE SPOUT UNIT

摘要

A container used in an aerosol type spout unit is made usable as a container used in a reciprocating pump type spout unit. A reciprocating pump (30) is mounted on the mouth of a container (20). And an injection button (38) is depressed to push in the piston (35) of the reciprocating pump to increase the pressure in a pressure chamber (b), and the piston is pushed down with respect to a stem (37) to let the contents of the pressure chamber into the injection button through a spout passageway (37a) and deliver them through a spout port (39a), while the operator removes his hand from the injection button, thus canceling the pushing-in of the piston, and releasing the pressure in the pressure chamber to lower the pressure in the pressure chamber, the piston being pushed up to open an inlet valve (36), sucking up the contents of the container into the pressure chamber. In such reciprocating pump type spout unit, the reciprocating pump is attached to an adapter (22) as by screws, and the peripheral edge of the adapter is attached to the curl portion (21) of the mouth of the container as by fitting.
