Inhalation apparatus
First Claim
1. An inhalation apparatus for dispensing a product comprising a housing, an end cap seated axially slidable relative to the housing and a collar in one or other of the end cap, or housing, said housing comprising a portion adapted to receive a pressurised dispensing container and being connected to a mouthpiece, and a duct communicating with the container receiving portion for conveyance of product towards the mouthpiece;
- said end cap comprising a portion for engaging a pressurised dispensing container;
said collar comprising an inwardly directed rim;
one of said end cap and said housing including an outwardly directed flange which fits within said rim;
said end cap being movable from a first position in which said rim and flange have an axial overlap and there is no or a minimal flow of air through said housing to a second position in which there is a maximum flow of air, the air flow being created by a user applying suction to the mouthpiece, wherein the collar is slidably moveable relative to its seat in the end cap or housing on a first actuation of the inhalation apparatus to axially position the collar relative to the end cap or housing to accommodate variations in the axial length of the valve stem of a pressurised dispensing container received, in use, in the housing.

Abstract
An inhalation apparatus for dispensing a product that includes a housing and an end cap axially slidable relative to the housing. The housing has a portion adapted to receive a pressurized dispensing container and connected to a mouthpiece, and duct means communicating with the container-receiving portion for conveyance of product toward the mouthpiece. The end cap has a socket for engaging the pressurized dispensing container. The end cap has a collar with an inwardly directed rim. The housing includes an outwardly directed flange which fits within the rim. The end cap is movable between a first position in which the rim and flange have an axial overlap and there is no or a minimal flow of air through the housing, and a second position in which there is a maximum flow of air, the air flow being created by a user applying suction to the mouthpiece.
