Abstract: A dispenser has a body 201 with a mouthpiece 202 and a pivoted mouthpiece cover 203. The mouthpiece is formed as an aperture 2021 in a separate body part 2012 clipped to a main body part 2011. The mouthpiece part is cut away 2014 with respect to the medicament can 211 fitted to the body to define an air inlet exposed by the cover when this is open. The cover is pivoted about an axis 204 low in the body at the joint between the two body parts. Integrally moulded with the cover 203 is a half round shaft 2031, which carries a cam arrangement 205 comprising a pair of cam lobes 2051, 2052 and an intermediate shaft 2053. The can 211 is held in an opening 210 at the upper end of the main body part 2011 by a pair of location pins 2101 in openings 2102 in sidewalls of the body part. A junction member 217 is slidably accommodated in the body with the ribs engaging in grooves 218 in its periphery.

Abstract: A breath actuated dispenser there-shown has a generally L-shaped hollow body 1 with a mouthpiece 2. An aerosol drug can 3 is mounted in the body. The can has a dispensing spout 4, which engages a receptor moulding 5 incorporating a living hinge 11, a movable outlet member 8 and a kink valve 9. A flap member 31 is pivotally mounted between the can and the receptor moulding. Breathing in through the dispenser by the patient will cause the flap to be drawn down against its spring 34. The outlet member is then tipped down by the spring 37 to point out of the mouthpiece 2, whence the dose is dispensed by opening of the kink valve.

Abstract: A dispenser 1 has a source of medicament 2 with a can 3 and a metered dose valve 4. The outlet stem 5 of the valve is fitted to a junction block 6 in a body 7 of the dispenser to which a breath actuated dose release mechanism 8 is connected for release of the medicament through a nozzle 9. The can has an acoustic transducer 11 attached to its side wall 12, in intimate acoustic contact. An electronic package 14, comprising a detection circuit and a driver for a LCD display 15 are also mounted on the can wall, the transducer being connected to the circuit. The detection circuit is arranged to decrement a count shown on the LCD by one for every detection of noise of dispensing/metering of a dose from the can. The detection circuit is programmed to compare the spectrum of the noise with a known dose-dispensing spectrum and to decrement the counter according to the comparison.

Abstract: A breath actuated dispenser there-shown has a generally L-shaped hollow body (1) with a mouthpiece (2). An aerosol drug can (3) is mounted in the body The can has a dispensing spout (4), which engages a receptor moulding (5) incorporating a living hinge (11), a movable outlet member (8) and a kink valve (9). A flap member (31) is pivotally mounted between the can and the receptor moulding. Breathing in through the dispenser by the patient will cause the flap to be drawn down against its spring (34). The outlet member is then tipped down by the spring (37) to point out of the mouthpiece (2), whence the dose is dispensed by opening of the kink valve.

Abstract: A drug dispenser (1) has a hollow body (2) with a housing (6) for a pressurised can (7) containing a drug and its propellant arranged on top of the body. The can has an outlet stem (8) received in a socket (9) in an internal spigot (10). This has a junction with a flexible tube (11), leading to a kink valve pair (12, 14). The tube continues on to a second internal spigot (15), having a spray nozzle (16) just within a breathing opening (5). The kink valve pair (12, 14) is formed as a moulding of the tube, with side wings (17). Towards the ends of the wings, they have thinner portions (17.1) at which there are apertures (18) immediately adjacent the tube. The arrangement, which is similar to that in my International Application No. PCT/GB01/03313, defines positions at which the tube kinks to close its through bore (19). The thinner portions are provided in two positions, which provide the two kink valves. An intermediate section (20) of the tube, with a predetermined volume is provided between the kink valves.

Abstract: A dispenser for a gaseous, gas borne or droplet substance contained in a source thereof, the dispenser including: a body (1) with a mouthpiece; (2) a junction member in the body for the substance source: and a breath actuable valve, (8) for controlling the release of the gas or liquid containing or comprising the substance, the valve comprising: a flexible tube for receiving the said gas or liquid, the tube extending from a valve inlet connected to the junction member and having a portion (21) which is kinkable for closure of the valve and movable to an open position in which the tube is un-kinked for opening of the valve; and a member arranged for movement in the body by inhalation to un-kink the valve: the tube being kinked to an obturating extent when the movable member is in a ready position and un-kinked when the movable member is moved on inhalation for release of the gas or liquid; wherein: the movable member is or includes a flap (7) arranged in the body for action of breath on it on inhalation: the j

Abstract: The dispenser (1) is for a medicament in an aerosol container (2), which is mounted in a body (3), within a sleeve (4) in a manner allowing air flow to pass the container, with the aerosol outlet tube (5) received in a socket (6) in a block (7) upstanding from the floor (8) of the body. The container is of the type which dispenses a measured dose on depression of the tube towards the container's body (9). The tube (5) is a gas tight seal in the socket (6). The block has a polyethylene tube (11) adhered into a side opening (12) of the block, in communication with the socket (6). The tube has a pair (13, 14) of kinks in it. Its end opposite from the block is adhered into a piston (15) at a throughbore (16). The piston is housed in a cylinder (17) formed in the body (3). To the outside of the cylinder is clipped an extension (18) of the body, having a mouthpiece (19) with an inhalation orifice (20). The arrangement provides an enlargement (21) in the bore (22) of the cylinder (17).
