Abstract

A canister arrangement for refilling a pharmaceutical dispenser. The dispenser can hold a predetermined number of pills, tablets, or capsules at one time. Since the canister arrangement can hold considerably more than the dispenser can, the canister is able to fill the dispenser to capacity multiple times before the canister must be refilled. The canister has a housing and one or more chambers in the housing. When a plurality of chambers is present, at least one of the chambers has a sloping floor at the bottom of the housing. A swinging door is disposed between each pair of adjacent chambers. The swinging door(s) are automatically activated when the dispensing apparatus senses that the dispenser and the previous chamber are both empty. An opening is also provided at the bottom of the housing. A sliding door covers the opening to prevent pills, tablets and capsules from exiting the housing. The sliding door is automatically opened upon the occurrence of an external condition, such as when the dispensing apparatus senses that the dispenser is empty.

Claims

1. A canister for use with a pharmaceutical dispensing apparatus comprising:

a) a housing;

b) a plurality of chambers in said housing, at least one of said plurality of chambers having a sloping floor at a lower extremity thereof;

c) a controlled aperture disposed between each pair of adjacent ones of said chambers;

d) a controller operatively connected to said controlled aperture and to said plurality of chambers for determining whether objects disposed in at least one of said plurality of chambers are to be refilled in bulk for eventual dispensing therefrom; and

e) an opening at a lower extremity of said housing.

2. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 1, further comprising:

f) a sliding door covering said opening to prevent pills, tablets and capsules from exiting said housing.

3. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 2, further comprising:

g) means for actuating said sliding door automatically upon the occurrence of an external condition.

4. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 1, wherein said plurality of chambers comprises three chambers and said controlled aperture disposed between each pair of adjacent ones of said chambers comprises two swinging doors.

10. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 1, wherein each of said plurality of chambers has a total capacity greater than the volume of a dispenser and at least one of said plurality of chambers has a capacity no greater than the capacity of said dispenser.

11. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 2, wherein control of said sliding door is automatic.

12. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 10, further comprising:

e) means for communicating between said dispenser and said canister;

f) means for locking said canister to said dispenser;

g) external indicator means; and

h) a loading door.

13. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 12, further comprising:

i) internal tamper evident indicator means operatively connected to said loading door; and

j) external tamper evident indicator means operatively connected to said loading door.

14. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 10, further comprising:

e) means operatively connected to said electronic control for internal identification of pills, tablets and capsules.

15. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 10, further comprising:

e) means operatively connected to said electronic control for external identification.

5. A pharmaceutical dispensing subunit comprising:

a) a canister comprising;

i) a first housing;

ii) a plurality of chambers in said first housing, at least one of said plurality of chambers having a sloping floor at a lower extremity thereof;

iii) a controlled aperture disposed between each pair of adjacent ones of said chambers;

iv) a controller operatively connected to said controlled aperture and to said plurality of chambers for determining whether objects disposed in at least one of said plurality of chambers are to be refilled in bulk for eventual dispensing therefrom; and

v) a first opening at a lower extremity of said housing; and

b) a dispenser comprising;

i′

) a second housing; and

ii′

) a second opening disposed at an upper extremity of said second housing, said second opening being in operative relationship with said first opening of said canister, whereby pills, tablets and capsules disposed in said canister are automatically transferred to said dispenser upon the occurrence of an external condition.

6. The pharmaceutical dispensing subunit in accordance with claim 5, further comprising:

c) a first sliding door covering said first opening to prevent pills, tablets and capsules from exiting said first housing; and

d) a second sliding door covering said second opening to prevent pills, tablets and capsules from entering said second housing.

7. The pharmaceutical dispensing subunit in accordance with claim 6, further comprising means for actuating said first and second sliding doors automatically upon the occurrence of an external condition to effect transfer of pills, tablets and capsules from said canister to said dispenser.

8. The pharmaceutical dispensing subunit in accordance with claim 5, wherein said plurality of chambers comprises three chambers and said swinging door disposed between each pair of adjacent ones of said chambers comprises two controlled apertures.

9. The pharmaceutical dispensing subunit in accordance with claim 8, further comprising:

c) means for actuating each of said controlled apertures automatically upon sensing said external condition.

16. A canister for use with a pharmaceutical dispensing apparatus comprising:

a) a housing;

b) a chamber in said housing;

c) a loading door;

d) a dispenser having means for determining whether objects disposed in said chamber are to be refilled in bulk for eventual dispensing thereby; and

e) an electrical connector to establish communications between said canister and a dispenser.

17. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 16, further comprising:

f) an opening at the lower extremity of said housing; and

g) a sliding door covering said opening to prevent pills, tablets and capsules from exiting said housing.

18. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 16, wherein said canister has a capacity no greater than the volume of a dispenser.

19. The canister for use with a pharmaceutical dispensing apparatus in accordance with claim 16, further comprising:

f) means for communicating between said canister and said dispenser;

g) means for locking said canister to said dispenser;

h) external indicator means;

i) internal tamper evident indicator means operatively connected to said loading door; and

i) external tamper evident indicator means operatively connected to said loading door.
