ИСПОЛНИТЕЛЬНЫЙ МЕХАНИЗМ АЭРОЗОЛЬНОГО КЛАПАНА

摘要

A camless aerosol valve actuator with a top portion mounted on and rotatable with respect to a bottom portion from an inoperative to an operative position. A first collar of the top portion has a side opening and a first central opening with a depressible finger pad mounted therein. A second collar of the bottom portion has a depressible product channel member with a nozzle positioned adjacent the second collar. A finger pad first protuberance overlies and aligns with the product channel member only in the operative actuator position. The nozzle aligns with the first collar side opening only in the operative actuator position, and the nozzle is blocked by the first collar in the inoperative position. A finger pad second protuberance braces the product channel member in the operative actuator position. The finger pad can be depressed downwardly in both the operative and inoperative positions, with the first protuberance moving below and bypassing the product channel member in the actuator inoperative rotated position. A support on the second collar connects to the product channel member by a frangible tag, and said support also provides a lower limit stop for the finger pad in both the operative and inoperative actuator positions. The finger pad first protuberance has a knife-edge which cooperates with an off-center groove in the product channel member in the operative position.
