SHUT-OFF MECHANISM, PUMP TYPE PRODUCT EQUIPPED WITH SHUT-OFF MECHANISM, AND AEROSOL TYPE PRODUCT EQUIPPED WITH SHUT-OFF MECHANISM

摘要

PROBLEM TO BE SOLVED: To simplify an operation by making rotational positioning between components unnecessary when a shut-off mechanism is assembled in a pump type product and an aerosol type product.;SOLUTION: A cam operational part of a bush (2) for retreating a check valve to shift to an operational mode by a cam action of the frame-like part (3b) of the check valve (3) to the discharging opening (4a) of an operational button, is formed into an annular inclined face (taper face 2e) consisting of an axial symmetry shape illustrated in a figure on a central axis (A) in the vertical direction. A spline engagement (1f and 2c) is adopted on preventing rotation between the operational button and the bush from occurring to dispense with positioning in the rotational direction during assembling.;COPYRIGHT: (C)2010,JPO&INPIT
