Articulated joint in aerosol medicament dispenser

摘要

A sliding and pivoting joint, and a retractable medicament spray dispenser having such a joint. A sleeve is telescopically mounted on the dispenser housing by engaging a pair of pin-like projections on a pair of ears on the sleeve into slots which are in opposite side walls of the housing. An elongated stud protrudes perpendicularly from the inward end of each pin. When the sleeve has been telescopically extended relative to the housing, abutments in the housing interact with the protruding studs to prevent the sleeve from being pivoted to any positions beyond those which correspond to the storage and the operating configurations of the dispenser.
