Abstract
An inhaler comprising a reservoir of an inhalable composition with an outlet at one end through which the inhalable composition is discharged. A non-metered breath-activated valve is provided between the one end and the reservoir, the breath-activated valve comprising a flow path extending from the reservoir to the outlet end. At least a portion of the flow path is a deformable tube. A clamping member pinches the deformable tube closed when no suction force is applied to the device and releases the tube to open the flow path when suction is applied at the outlet, to provide uninterrupted flow from the reservoir to the outlet.
Claims20
An inhaler comprising:
- a reservoir of an inhalable composition;
- an outlet at one end through which the inhalable composition is discharged;
- a fill valve at the opposite end to the one end and via which the reservoir can be filled;
- and
- a non-metered breath-activated valve between the one end and the reservoir, the breath-activated valve comprising a flow path extending from the reservoir to the outlet end, at least a portion of the flow path being a deformable tube, and a clamping member which pinches the deformable tube closed when no suction force is applied to the inhaler and releases the tube to open the flow path when suction is applied at the outlet, to provide uninterrupted flow from the reservoir to the outlet;
- wherein from the one end to the opposite end, the following components are arranged in order:
- the outlet, the clamping member, the reservoir, and the fill valve.
An inhaler comprising:
- a reservoir of an inhalable composition;
- an outlet at one end through which the inhalable composition is discharged;
- and
- a non-metered breath-activated valve between the one end and the reservoir, the breath-activated valve comprising a flow path extending from the reservoir to the outlet end, at least a portion of the flow path being a deformable tube, and a clamping member which pinches the deformable tube closed when no suction force is applied to the inhaler and releases the tube to open the flow path when suction is applied at the outlet, to provide uninterrupted flow from the reservoir to the outlet;
- wherein the tube is pinched at a single location.
An inhaler comprising:
- a reservoir of an inhalable composition;
- an outlet at one end through which the inhalable composition is discharged;
- and
- a non-metered breath-activated valve between the one end and the reservoir, the breath-activated valve comprising a flow path extending from the reservoir to the outlet end, at least a portion of the flow path being a deformable tube, and a clamping member which pinches the deformable tube closed when no suction force is applied to the inhaler and releases the tube to open the flow path when suction is applied at the outlet, to provide uninterrupted flow from the reservoir to the outlet;
- wherein the deformable tube is a nozzle which is also provided integrally with an outlet orifice, which is the narrowest part of the flow path.
