Abstract

A blister pack for an inhaler, the blister pack comprising a blister support (10) with a plurality of blisters (11), each blister (11) being hermetically sealed by a closure layer (20), the blister support (10) being in the form of an elongate strip, the blisters (11) being disposed one after the other along said blister support strip, said blister support (10) including two lateral profiles (15), one on either longitudinal side of said blister support (10), said lateral profiles being formed by alternating depressions (18) and projections (16), each projection including an abutment surface (17) for displacing said blister pack in accurate manner each time said inhaler is actuated, each abutment surface (17) being connected to the adjacent abutment surface (17) via a slide surface (19) formed by each depression.

Claims

1. A blister pack for an inhaler, the blister pack comprising a blister support (10) with a plurality of blisters (11), each blister (11) being hermetically sealed by a closure layer (20), the blister support (10) being in the form of an elongate strip, the blisters (11) being disposed one after the other along said blister support strip, said blister support (10) including two lateral profiles (15), one on either longitudinal side of said blister support (10), said lateral profiles being formed by alternating depressions (18) and projections (16), each projection including an abutment surface (17) for displacing said blister pack in accurate manner each time said inhaler is actuated, the blister pack being characterized in that each abutment surface (17) is connected to the adjacent abutment surface (17) via a slide surface (19) formed by each depression.

2. A blister pack according to claim 1, in which said abutment surface (17) is formed by a wall (17) that is approximately transverse relative to the direction along which the blisters (11) extend over said blister support (10).

3. A blister pack according to claim 1, in which each abutment surface (17) is approximately perpendicular to the longitudinally-extending edges of said strip-shaped blister support (10).

4. A blister pack according to claim 1, in which said blister support (10) is an elongate flexible strip that is suitable for being rolled up so as to be mounted in an inhaler.

5. A blister pack according to claim 1, in which each blister (11) is formed by a cavity, in particular a rigid cavity, containing one dose of powder to be dispensed by said inhaler.

6. An inhaler, characterized in that it includes a blister pack according to claim 1.

7. An inhaler according to claim 6, further including drive means (30) adapted to co-operate, on each actuation, with a projection (16) of said at least one lateral profile (15), so as to displace said blister pack in accurate manner.
