Title:
MECHANISM FOR MIXING AND DISCHARGING MULTIPLE SEPARATE CONTENTS, AND AEROSOL PRODUCT PROVIDED WITH SAID MECHANISM FOR MIXING AND DISCHARGING
Document Type and Number:
WIPO Patent Application WO/2021/054166
Kind Code:
A1
Abstract:
The present invention is directed to the improvement of a moving valve member in a shared passageway in a mechanism, for mixing and discharging contents, where first and second contents separately housed within an aerosol container are, as a result of a discharge operation performed using a single discharge part, discharged in a mixed state via first and second stems constituting respective upstream valves and via the movable valve member in the downstream shared passageway. The present invention comprises a cam member 14 and a cam follower 13b that, in tandem with a discharge operation performed on an operating surface 15a, set a movable valve member 13 of a shared passageway 12c to an open state. The downward movement of the cam member 14 caused by the discharge operation first causes a first stem 3 and a second stem, which function as respective upstream valves for the first and second contents, to shift, against weak elastic force, from a previously closed state to an open state, followed by the cam action of the cam member 14 and the cam follower 13b causing the movable valve member 13 to slide rearward, against strong elastic force from a lateral coil spring 13d, and shift from a previously closed state to an open state.
