Blister assembly for inhalation device
First Claim
1. A blister pack with 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, wherein each abutment surface (17) is connected to the directly adjacent abutment surface (17) via a slide surface (19) formed by each depression;
- andeach abutment surface and each slide surface is angled relative to each other and relative to a direction along which the blisters extend over the blister support;
wherein, upon each actuation, a drive mechanism that is positioned in one of the depressions and in contact with an associated abutment surface of the depression of at least one of the two lateral profiles advances the blister strip by pressing against the associated abutment surface, and moving from said one of the depressions into the next one of the depressions after the drive mechanism advances the blister strip so that the drive mechanism engages each of the depressions sequentially, said slide surface enabling the drive mechanism to be displaced in regular manner between two depressions.

9. A blister pack with an inhaler, comprising:
-
a blister support comprising a plurality of blisters, each blister sealed by a closure layer, the blister support having a form of an elongate strip with the blisters disposed one after the other along the blister support strip; the blister support comprising a first lateral profile on a longitudinal side of the blister support, the first lateral profile comprising alternating depressions and projections, each projection comprising an abutment surface configured to displace the blister pack each time the inhaler is actuated, each abutment surface is connected to a directly adjacent abutment surface via a slide surface formed by each depression;
each abutment surface and each slide surface extending at an angle relative to each other and relative to a direction along which the blisters extend over the blister support; andwherein upon each actuation, a drive mechanism that is positioned in one of the depressions and in contact with an associated abutment surface of the depression advances the blister strip by pressing against the associated abutment surface, and moving from said one of the depressions into a directly adjacent one of the depressions after the drive mechanism advances the blister strip so that the drive mechanism engages each of the depressions sequentially, said slide surface enabling the drive mechanism to be displaced between the directly adjacent abutment surfaces for sequential engagement of the depressions. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
