Abstract:
1. Dispensing device for dispensing a formulation as a spray, comprising: a mouthpiece through which the formulation is delivered as a spray, a storage device with multiple separate and pre-metered doses of the formulation in annularly arranged receptacles, each receptacle comprising a cavity with a moveable insert containing a respective dose of the formulation, each cavity being sealed at an outlet side by a seal, wherein each insert comprises an opening means for facilitating opening of the seal by movement of the respective insert through the seal, the opening means being located at an outlet opening of one of the cavity and the receptacle and only at one side of the seal at the outlet opening so that the seal is pivoted mainly to an opposite side of the outlet opening by said movement for minimizing potential interference by the opened seal with flowing of the formulation from the receptacle toward the mouthpiece, and wherein each insert comprises a storage chamber containing said pre-metered doses of the formulation and a duct extending within each insert from an inlet end fixed at a wall of said storage chamber to an outlet end fixed at said opening means, said outlet end being positioned for directly discharging the formulation as a spray into said mouthpiece.
