Abstract

An indicating device includes an indicating portion and an actuator portion. At least a part of the indicating portion is moveable with a container between engaged and disengaged positions relative to a dispenser housing. The indicating portion includes at least one indicator member. The container is moveable relative to the at least one indicator member along the longitudinal axis when the container is in the engaged position.

Claims

1. A dispenser assembly:

a dispenser housing;

a container comprising an end portion and a valve moveable between a closed position and an open position, said container dispensing metered dosages of substance when said valve is moved to said open position, wherein said container is moveable relative to said dispenser housing between an engaged position and a disengaged position, wherein said container is removeably connected to said dispenser housing and is moveable relative to said dispenser housing along a longitudinal axis when in said engaged position, and wherein said container is disconnected from said dispenser housing when in said disengaged position;

an indicating device comprising an indicating portion and an actuator portion, wherein at least said indicating portion is moveable with said container between said engaged and disengaged positions, and wherein said indicating portion comprises at least one indicator member, wherein said container is moveable relative to said at least one indicator member along said longitudinal axis when said container is in said engaged position.

2. The dispenser assembly of claim 1 wherein said container comprises a valve stem connected to said dispenser housing and moveable between a closed position and open position corresponding to said closed and open positions of said valve.

3. The dispenser assembly of claim 1 wherein said at least one indicator member is moveably secured to said container adjacent said end portion.

4. The dispenser assembly of claim 1 wherein said at least one indicator member is rotatably moveable about said longitudinal axis.

5. The dispenser assembly of claim 4 wherein said at least one indicator member comprises a plurality of indicator members.

6. The dispenser assembly of claim 5 wherein said plurality of indicator members comprises at least first, second and third indicator members, wherein said actuator portion is selectively engaged with said first indicator member upon a first predetermined number of reciprocal movements of said container relative to said dispenser housing along said longitudinal axis, wherein said first indicator member is selectively engaged with said second indicator member upon a predetermined number of incremental rotational movements of said first indicator member and wherein said second indicator member is selectively engaged with said third indicator member upon a predetermined number of incremental rotational movements of said second indicator member.

7. The dispenser assembly of claim 6 wherein said first predetermined number is one and wherein said predetermined number of incremental rotations movements of each of said first and second indicator members is ten.

8. The dispenser assembly of claim 1 wherein said indicator member comprises a liquid crystal display.

9. The dispenser assembly of claim 1 wherein said indicating portion comprises a collar secured to said end portion of said container.

10. The dispenser assembly of claim 9 wherein said at least one indicator member is retained by said collar and further comprising a housing, said housing comprising an indexing portion releasably engaging said at least one indicator member, wherein said container and said collar are moveable relative to said at least one indicator member and said housing along said longitudinal axis.

11. The dispenser assembly of claim 10 wherein said at least one indicator member comprises at least one first indicator member having an advancement member and at least one second indicator member having an drive portion, wherein said at least one first and second indicator members are each rotatably mounted about said longitudinal axis, and wherein said housing comprises an engagement portion selectively biasing said advancement member into engagement with said drive portion as said at least one indicator member is rotated about said longitudinal axis.

12. The dispenser housing of claim 1 wherein said actuator portion is connected to said dispenser housing and remains connected thereto as said container and said indicating portion are moved from said engaged position to said disengaged position.

13. The dispenser assembly of claim 12 wherein said actuator portion comprises a drive gear and wherein said at least one indicator member comprises a driven gear selectively engaged by said drive gear.

14. An indicating device kit suitable for indicating the number of metered dosages that have been dispensed from or remain in a container, said kit comprising:

an indicating portion comprising a collar adapted to be mounted to the container and at least one indicator member connected to said collar and moveable relative thereto along a longitudinal axis; and

an actuator portion separate from said indicating portion and adapted to advance said at least one indicator member.

15. The indicating kit of claim 14 wherein said indicating portion further comprises a housing comprising an indexing portion releasably engaging said at least one indicator member.

16. The indicating kit of claim 15 wherein said at least one indicator member comprises at least one first indicator member having an advancement member and at least one second indicator member having an drive portion, wherein said at least one first and second indicator members are each rotatably mounted about said longitudinal axis, and wherein said housing comprises an engagement portion selectively biasing said advancement member into engagement with said drive portion as said at least one indicator member is rotated about said longitudinal axis.

17. The indicating kit of claim 16 wherein said actuator portion comprises a drive gear and wherein said at least one first indicator member comprises a driven gear selectively engaged by said drive gear.

18. The indicating kit of claim 14 wherein said at least one indicator member is rotatable about said longitudinal axis.

19. The indicating kit of claim 14 wherein said at least one indicator member comprises a plurality of indicator members.

20. The indicating kit of claim 19 wherein said plurality of indicator members comprises at least first, second and third indicator members, wherein said actuator portion is selectively engageable with said first indicator member, wherein said first indicator member is selectively engageable with said second indicator member and wherein said second indicator member is selectively engageable with said third indicator member.

21. The indicating kit of claim 14 wherein said at least one indicator member comprises a liquid crystal display.

22. An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container, said indicating device comprising:

means for mounting at least a portion of said indicating device to the container; and

means for indicating the number of metered dosages that have been dispensed from or remain in the container, wherein said means for indicating is connected to said means for mounting and is moveable relative thereto along a longitudinal axis.
