Abstract

An indicating device for a dispenser that dispenses metered dosages of a medicament from a container having a valve moveable between a closed position and an open position. The indicating device includes an indicator housing having a first cover with a first vertical wall and a second cover with a second vertical wall. One of the first or second covers includes a base defining a lower surface of the indicator housing, and the other of the first or second covers includes a top defining an upper surface of the indicator housing. The first and second covers are joined with the first and second vertical walls and the base and the top defining an interior space therebetween. An indicator is rotatably disposed in the interior space of the indicator housing, with the indicator including dosage indicia. A dispensing device includes a dispenser housing and an indicating device.

First claim

What is claimed is:

1. A dispensing device for dispensing metered dosages of a medicament from a container, the dispensing device comprising:
a dispenser housing having an interior surface defining a cavity, said dispenser housing comprising a support block having a well, said support block defining a longitudinal axis and having an outer surface;
an indicator housing comprising a first cover comprising a first vertical wall disposed adjacent said interior surface of said dispenser housing and a second cover comprising a second vertical wall disposed adjacent said outer surface of said support block, wherein one of the first or second covers comprises a base defining a lower surface of said indicator housing, and the other of the first or second covers comprises a top defining an upper surface of said indicator housing, wherein said first and second covers are joined with said first and second vertical walls and said base and said top defining an interior space therebetween; and
an indicator rotatably disposed in said interior space of said indicator housing, said indicator comprising dosage indicia.

2. The dispensing device of claim 1 further comprising said container having a valve stem disposed in said well, wherein said container holds a medicament.

3. The dispensing device of claim 1 wherein said first vertical wall comprises an outer convex surface.

4. The dispensing device of claim 3 wherein said second vertical wall comprises an outer concave surface.

5. The dispensing device of claim 4 wherein said outer concave surface mates with said outer surface of said support block.

6. The dispensing device of claim 1 wherein said first and second cover members are joined with a snap fit.

7. The dispensing device of claim 1 wherein said first vertical wall comprises a first viewing window, wherein said dosage indicia of said indicator are visible through said first viewing window.

8. The dispensing device of claim 7 wherein said dispenser housing comprises a second viewing window aligned with said first viewing window, wherein said dosage indicia of said indicator are visible through said second viewing window.

9. The dispensing device of claim 1 wherein said indicator is coupled to at least one of said first and second covers with a snap fit.

10. An indicating device for a dispenser that dispenses metered dosages of a medicament from a container having a valve moveable between a closed position and an open position, said indicating device comprising:
an indicator housing comprising a first cover comprising a first vertical wall and a second cover comprising a second vertical wall, wherein one of the first or second covers comprises a base defining a lower surface of said indicator housing, and the other of the first or second covers comprises a top defining an upper surface of said indicator housing, wherein said first and second covers are joined with said first and second vertical walls and said base and said top defining an interior space therebetween; and
an indicator rotatably disposed in said interior space of said indicator housing between said first and second vertical walls, said indicator comprising dosage indicia.

11. The indicating device of claim 10 wherein said first vertical wall comprises an outer convex surface.

12. The indicating device of claim 11 wherein said second vertical wall comprises an outer concave surface.

13. The indicating device of claim 10 wherein said first and second cover members are joined with a snap fit.

14. The indicating device of claim 10 wherein said first vertical wall comprises a first viewing window, wherein said dosage indicia of said indicator are visible through said first viewing window.

15. The indicating device of claim 10 wherein said indicator is coupled to at least one of said first and second covers with a snap fit.
