Abstract

A pill dispenser is provided with a floor, a rotor rotatably coupled adjacent the floor, a base coupled to the rotor, and an indexing mechanism coupled to the rotor to index the rotor in a rotational direction relative to the base to a plurality of index positions. The floor is adapted to be coupled to a shell to define an inner cavity for receiving pills. The floor has a funneled opening extending therethrough. The rotor has a plurality of pill receptacles extending from a top surface to a bottom surface and a plurality of corresponding separation ramps. Each separation ramp extends from the top surface downward to connect with one side of the corresponding pill receptacle. In each of the index positions, one of the pill receptacles aligns with an exit of the funneled opening and another of the pill receptacles aligns with a pill-dispense opening of the base.

Claims

1. A pill dispenser comprising:

a floor adapted to be coupled to a shell to define an inner cavity disposed above the floor for receiving a plurality of pills, the floor having a funneled opening extending therethrough, wherein the funneled opening has an entrance at a top of the floor and a smaller exit below the entrance at a bottom of the floor;

a rotor rotatably coupled adjacent the bottom of the floor and having a plurality of pill receptacles extending from a top surface to a bottom surface of the rotor and a plurality of corresponding separation ramps, wherein each separation ramp extends from the top surface downward to connect with one side of the corresponding pill receptacle; and

a base coupled to the rotor opposite the floor and having a pill-dispense opening; and

an indexing mechanism coupled to the rotor to index the rotor in a rotational direction relative to the base to a plurality of index positions, wherein in each of the index positions one of the pill receptacles aligns with the exit of the funneled opening and another of the pill receptacles aligns with the pill-dispense opening.

2. The pill dispenser of claim 1, wherein the funneled opening defines a longitudinal axis, and wherein the entrance and exit of the funneled opening is centered around the longitudinal axis.

3. The pill dispenser of claim 1, wherein the funneled opening gradually reduces in size between the entrance and exit.

4. The pill dispenser of claim 1, wherein the funneled opening includes a rounded region between the entrance and exit.

5. The pill dispenser of claim 1, wherein the floor has a plurality of funneled openings extending therethrough that are circumferentially spaced.

6. The pill dispenser of claim 5, wherein the top of the floor has a raised center section that extends radially outwardly from a rotor shaft disposed along a central longitudinal axis that extends through a center of the rotor, and wherein the top of the floor has a raised outer section that extends radially inwardly from an outer perimeter of the floor, the raised center and outer sections extending downward to connect with entrances of the funneled openings.

7. The pill dispenser of claim 1, further comprising an agitator coupled to a rotor shaft of the rotor and disposed within the inner cavity, wherein the agitator agitates the pills residing in the inner cavity.

8. The pill dispenser of claim 1, wherein each separation ramp extends from the top surface of the rotor downwards to an intermediate height of the corresponding pill receptacle, the intermediate height being measured from the bottom surface of the rotor and being less than a large dimension of the pills.

9. The pill dispenser of claim 1, further comprising an indicator window over an outer wall of the rotor such that in each of the index positions, dosage indicia included on the outer wall of the rotor is viewable through the indicator window.

10. A pill dispenser comprising:

a floor adapted to be coupled to a shell to define an inner cavity for storing a plurality of pills, the floor having a funneled opening extending therethrough;

a rotor rotatably coupled to the floor and having a plurality of pill receptacles extending from a top surface to a bottom surface of the rotor and a plurality of corresponding separation ramps, wherein each separation ramp extends from the top surface downward to an intermediate height of the corresponding pill receptacle, wherein each pill receptacle has a width for containing a small dimension of the pills and a total height greater than the intermediate height, the intermediate height being less than a large dimension of the pills;

a base coupled to the rotor opposite the floor and having a pill-dispense opening; and

an indexing mechanism coupled to the rotor to index the rotor in a rotational direction relative to the base to a plurality of index positions, wherein in each of the index positions one of the receptacles of the plurality aligns with the pill-dispense opening.

11. The pill dispenser of claim 10, wherein the funneled opening has an entrance at a top of the floor and a smaller exit below the entrance at a bottom of the floor.

12. The pill dispenser of claim 11, wherein the funneled opening defines a longitudinal axis, and wherein the entrance and exit of the funneled opening is centered around the longitudinal axis.

13. The pill dispenser of claim 10, wherein the intermediate height is in the range of 65% to 85% of the total height.

14. The pill dispenser of claim 10, wherein the intermediate height is 75% of the total height.

15. A pill dispenser comprising:

a shell having an inner cavity to receive a plurality of pills, the shell having a plurality of funneled openings defined along a floor of the shell, each funneled opening sized to receive at least one of the plurality of pills;

a rotor coupled to the shell adjacent the floor and having a plurality of pill receptacles extending through the rotor;

a base coupled to the rotor opposite the shell and having a pill-dispense opening; and

an indexing mechanism coupled to the rotor to index the rotor relative to the base to a plurality of index positions, wherein in each index position one of the funneled openings aligns with one of the pill receptacles and one of the pill receptacles aligns with the pill-dispense opening.

16. The pill dispenser of claim 15, further comprising an agitator coupled to a rotor shaft of the rotor and disposed within the inner cavity, wherein the agitator agitates the pills residing in the inner cavity.

17. The pill dispenser of claim 16, wherein the agitator includes at least one agitator finger extending downward from the rotor shaft at an angle relative to the rotor shaft, the at least one agitator finger having a length to agitate pills adjacent entrances of the funneled openings.

18. The pill dispenser of claim 15, wherein the base has a plate abutting a bottom of the rotor, the plate having a slot aligned with the pill-dispense opening.

19. The pill dispenser of claim 15, wherein the indexing mechanism includes an actuation lever rotatably coupled to a support shaft of the base, a biasing member coupled to the actuation lever for biasing the actuation lever opposite a rotational direction of the rotor, and an indexing leaf spring coupled to the actuation lever and biased upwards to engage with a plurality of indexing ramps disposed on a bottom of the rotor.

20. The pill dispenser of claim 15, wherein each of the funneled openings extends through the floor and includes an entrance at a top of the floor, an exit below the entrance at a bottom of the floor, and a rounded region between the entrance and exit.
