Abstract
A dispenser cap for an "aerosol can" container comprises a fixed cap body and a push button within the cap body. The push button is articulated to guides of the cap body, these guides including notches to abut the crimped rim of the valve carrying cap of the aerosol container for which the cap is intended. The articulation is achieved by means of trunnion elements of the push button resiliently engaging in corresponding recesses of the guides of the cap body.
Claims16
A dispenser cap for a pressurised container of the "aerosol can" type having an annular crimped rim and a valve mounting cap carrying a discharge valve to be actuated by said dispenser cap and an outlet member to discharge fluid through said dispenser cap, when actuated, such cap comprising:
- (a) first and second cap parts, the first cap part comprising a generally cylindrical cap body and said second part of the cap comprising a push button movable within said generally cylindrical cap body;
- (b) catch engagement means for fixing said first cap part on the side wall of a said pressurised container;
- (c) a top panel to said first cap part;
- (d) means on said first cap part defining guides integral with the said cap body and connected to said top panel of the first cap part for guiding said push button for pivotal movement within said first cap part;
- (e) an ejection nozzle connected to said push button;
- (f) means on said push button defining a duct of bent shape having an axial branch for cooperating with the outlet member of a said associated container and a radial branch which communicates with said ejection nozzle;
- (g) operating tongue means connected to said push button extending at least in a zone thereof remote from said radial branch of the duct, and substantially perpendicular to said axial branch of the duct means, said push button having a length measured perpendicular to the axis of the cap body which is substantially equal to the inner diameter of the said cap body said operating tongue means of the push button being substantially disposed at the level of said top panel of the first cap part;
- (h) an extension of said push button adjacent to said ejection nozzle, said extension being parallel to said axial branch of the duct means and aligned in a direction which extends toward said catch engagement means of the first cap part, said extension having a proximal end near said ejection nozzle and a distal end remote therefrom;
- (i) two coaxial pin means adjacent said distal end of the extension for articulating the push button on the cap body;
- (j) means on said cap body defining a window in register with said ejection nozzle of the push button;
- (k) means defining recesses arranged at the bottom of said guides of the cap body, said recesses opening downwardly toward the container and arranged near said window thereof receiving said pin means and thereby defining an axis of articulation substantially at the level of the end of said discharge valve outlet member, said two coaxial pin means being integral with the said extension and being catch-engaged within said recesses;
- and
- (l) means on said guide means adapted to abut the annular crimped rim of a said pressurised container discharge valve mounting cup when the dispenser cap is catch-engaged on the said container.
