Abstract

A dispenser (1) comprises a can (2) and body (3). The can is an aluminum extrusion with a valve crimped into its mouth, the valve having an outlet spout (4). The crimped region (5) of the can surrounding the valve has a lesser diameter than the can has through the main part (6) of its length. The body has a mouthpiece (11) with a pivotal cover (12) drivingly connected to a cam (13). This bears on the underside of junction member (14), into a socket (15) of which the spout 4 fits. A breath actuated dose release mechanism (16) is provided. The body has a tubular section (7) for receiving the necked down region (5) of the can. A printed paper label (21) is wrapped around the joint between the body and the can to unite the can to the body in position such that when the cover is opened, a dose is dispensed by the cam (13) lifting the junction member and depressing the spout.

Dependent claims

A dispenser for a gaseous, gas borne or droplet substance contained in a source thereof, the dispenser comprising:

a substance source having:
an external surface devoid of any feature intended for longitudinal location of the source and
a spout displaceable inwards of the source to a dispense position for dispensing a substance dose from the source;
a body having:
a mouthpiece via which the substance dose can be inhaled and
a socket sized for lateral location of the source via its external surface, but devoid of any body feature intended for longitudinal location thereof;
a junction member for the spout, the junction member being arranged in the body to be slidable to a set position for displacing the spout to its dispense position;
an action for slidably moving the junction member to the set position;
and
a unification of the source or a source locator to the body for locating the source longitudinally with the spout in its dispense position when the junction member is in its set position, the locator where provided extending from the body, outside the source and at least partially across the end of the source to provide a longitudinal location for the source, locating it when the movable junction member acts to depress the spout inwards of the source.

7 more elements

A method in the production of a dispenser for a gaseous, gas borne or droplet substance contained in a source thereof, the dispenser comprising:

a substance source having:
an external surface devoid of any feature intended for longitudinal location of the source and
a spout displaceable inwards of the source to a dispense position for dispensing a substance dose from the source;
a body having:
a mouthpiece via which the substance dose can be inhaled and
a socket sized for lateral location of the source via its external surface, but devoid of any body feature intended for longitudinal location thereof;
a junction member for the spout, the junction member being arranged in the body to be slidable to a set position for displacing the spout to its dispense position;
an action for slidably moving the junction member to the set position;
and
a unification of the source or a source locator to the body for locating the source longitudinally with the spout in its dispense position when the junction member is in its set position, the locator where provided extending from the body, outside the source and at least partially across the end of the source to provide a longitudinal location for the source, locating it when the movable junction member acts to depress the spout inwards of the source,
the method comprising the steps of:
arranging the junction member in the body at its set;
longitudinally assembling the source to the body, with the spout engaged with the junction member;
temporarily holding the body and the source in a unification position with the spout in its dispense position and the junction member still in its set position;
and
unifying the body and the source together to fix them in their unified position.
