Abstract

A medicament dispensing device for dispensing metered dosages of medicaments from a container. The device includes a container and an indicating device. The container has a first end and an opposite second end spaced from the first end along a longitudinal axis. The first end includes a valve stem extending longitudinally therefrom and moveable between a closed position and an open position. The container contains a plurality of metered dosages of medicaments, with the valve stem dispensing one of the plurality of metered dosages when the valve stem is moved to the open position. The second end has an end surface. The indicating device includes a housing and an indicator member disposed in the housing. The housing is mounted to the second end of the container with a bottom surface thereof disposed adjacent the end surface of the second end of the container. The housing and the second end of the container have substantially the same shape.

2. The medicament dispensing device of claim 1 wherein said end surface and said bottom surface are each curved.

3. The medicament dispensing device of claim 2 wherein said end surface is concave and said bottom surface is convex.

4. The medicament dispensing device of claim 1 wherein said container comprises a cylinder and wherein said first cross-sectional shape is a first circle having a first diameter, and wherein said second cross-sectional shape is a second circle having a second diameter, wherein said first and second diameters are substantially identical.

5. The medicament dispensing device of claim 1 wherein said housing comprises a base member defining said bottom surface and said outermost periphery of said housing and a cap member moveably connected to said base member, said cap member moveable relative to said base member along said longitudinal axis.

6. The medicament dispensing device of claim 5 wherein said indicator member is rotatably mounted in said cap member about an axis substantially parallel to said longitudinal axis.

7. The medicament dispensing device of claim 5 wherein said base member comprises a skirt defining a cavity and said outermost periphery of said housing, and wherein at least a portion of said cap member is received in said cavity as said cap member is moved relative to said base member along said longitudinal axis.

8. The medicament dispensing device of claim 1 further comprising an actuator housing having a longitudinally extending cavity and a well located at a bottom of said cavity, said actuator housing having a generally open end at a top of said cavity, and wherein said container is disposed in said cavity of said actuator housing with said valve stem inserted in said well, wherein said second end of said container with said indicating device mounted thereto extends from the generally open end of said actuator housing so as to be exposed to the user, said container and said indicating device reciprocally moveable within said housing along said longitudinal extent of the cavity such that said valve stem is moved between said open and closed position by engagement with said well.

9. The medicament dispensing device of claim 1 wherein said housing is bonded to said second end of said container.

10. A medicament dispensing device for dispensing metered dosages of medicaments from a container comprising:

said container having a first end and an opposite second end spaced from said first end along a longitudinal axis, said first end comprising a valve stem extending longitudinally therefrom and moveable between a closed position and an open position, said container containing a plurality of metered dosages of medicaments, said valve stem dispensing one of said plurality of said metered dosages when said valve stem is moved to the open position, said container comprising a first cylinder defining said second end, wherein said second end has an end surface and said first cylinder has a first diameter; and

an indicating device comprising a housing and an indicator member disposed in said housing, said housing comprising a second cylinder having a bottom surface, wherein said housing is mounted to said second end of said container with said bottom surface disposed adjacent to said end surface of said second end of said container, and wherein said second cylinder has a second diameter, wherein said second diameter is not greater than said first diameter and wherein no portion of said indicating device extends laterally outwardly beyond said second diameter.

11. The medicament dispensing device of claim 10 wherein said first diameter is substantially the same as said second diameter.

12. The medicament dispensing device of claim 10 wherein said end surface and said bottom surface are each curved.

13. The medicament dispensing device of claim 12 wherein said end surface is concave and said bottom surface is convex.

14. The medicament dispensing device of claim 10 wherein said housing comprises a base member defining said second cylinder and said bottom surface and a cap member moveably connected to said base member, said cap member moveable relative to said base member along said longitudinal axis.

15. The medicament dispensing device of claim 14 wherein said indicator member is rotatably mounted in said cap member about an axis substantially parallel to said longitudinal axis.

16. The medicament dispensing device of claim 14 wherein said base member comprises a skirt defining said second cylinder and a cavity formed therein, and wherein at least a portion of said cap member is received in said cavity as said cap member is moved relative to said base member along said longitudinal axis.

17. The medicament dispensing device of claim 10 further comprising an actuator housing having a longitudinally extending cavity and a well located at a bottom of said cavity, said actuator housing having a generally open end at a top of said cavity, and wherein said container is disposed in said cavity of said actuator housing with said valve stem inserted in said well, wherein said second end of said container with said indicating device mounted thereto extends from the generally open end of said actuator housing so as to be exposed to the user, said container and said indicating device reciprocally moveable within said housing along said longitudinal extent of the cavity such that said valve stem is moved between said open and closed position by engagement with said well.
