Abstract

A one-at-a-time pill container and dispenser having a mechanism which allows for use of the device with existing containers. A child-proof lock is provided. The device has a mechanism for ensuring that only a single pill is brought into the dispensing chamber as a consequence of a partial rotation of the cap with respect to the bottle body. A reverse partial rotation of the cap then allows the pill to fall by gravity into the user'"'"'s hand. The two-directional rotation to cause pill dispensing is easy for an adult but highly unlikely to be accidentally duplicated by a child. The mechanism is a series of wedge shaped chambers, sized for the capsule to be dispensed, with a covering flange over the dispensing chamber, to ensure that only a single capsule enters the dispensing aperture. The chambers are caused to be rotated by the mating engagement of the cap, via a pawl, with a segment shaped slot in the top of the dispensing mechanism.

Claims

1. A one at a time capsule storage and dispenser device comprising:

a) a bottle portion for holding capsules having a neck portion;

b) a cap secured to said neck portion and capable of relative rotational motion with respect to said bottle portion, said cap having an opening, said cap being provided with a downwardly extending pawl means;

c) a holding plate secured to said bottle having an opening only slightly larger than the size of the capsules to be dispensed by said device and an arcuate window, said pawl means extending through said window and capable of rotational movement within said window when said cap is rotated with respect to said bottle; and

d) a wheel-like component comprised of a plurality of capsule holding chambers and capable of rotation along with rotation of said cap by the mechanical interengagement of said pawl means with one of said capsule holding chambers such that rotation of said cap causes one of said capsule holding chambers to become aligned with said hole of said holding plate to allow a capsule to be dispensed.

2. A device as claimed in claim 1 wherein said cap comprises a door hinged to the top surface of said cap.

3. A device as claimed in claim 2 wherein said cap is further provided with child proof means to prevent said door from being opened unless said child proof means is first disabled.

4. A device as claimed in claim 3 wherein said child proof means comprises a ring segment which is rotatable to overlay said door to block access to the contents of the device and rotatable so as not to overlay said door to allow said door to be opened to provide access to the contents of said device.

5. A device as claimed in claim 2 further comprising a door holding means for holding said door in the open position, said door holding means comprising an arcuate section on said door which frictional engages a pair of opposed notches of said cap.

6. A device as claimed in claim 5 further comprising a child proof mechanism comprising a ring segment which is rotatable to overlay said door to block access to the contents of said device and rotatable so as not to overlay said door to allow said door to be opened to provide access to the contents of said device, said arcuate section also serving to prevent said ring segment from being removed from said cap.

7. A device as claimed in claim 1 wherein said cap is provided with child proof means.

8. A device as claimed in claim 1 wherein said holding plate is provided with a ceiling matching the dimensions of one of said capsule holding chambers.

9. A device as claimed in claim 1 wherein said holding plate is provided with a ceiling which directs a capsule from said capsule holding chamber, through said hole in said holding plate, when said cap is rotated with respect to said bottle.

10. A device as claimed in claim 1 wherein said holding plate is provided with a locking tooth and said wheel-like component is provided with two or more ratchet teeth for ensuring one-way rotation of said wheel-like component with respect to said bottle, even if said bottle is rotated in two directions of rotation.

11. A device as claimed in claim 1 wherein said pawl means rotates said capsule holding chambers in a first direction of rotation when said cap is rotated with respect to said bottle in said first direction of rotation and said pawl means cams over said capsule holding chambers when said cap is rotated in a second, opposite direction of rotation with respect to said bottle.

12. A device as claimed in claim 1 wherein said wheel-like component is provided with at least one sweeping arm for agitating the capsules contained within the bottle during rotation of said cap with respect to said bottle.

13. A device as claimed in claim 1 further comprising a moisture absorbent canister.

14. A device as claimed in claim 13 wherein said moisture absorbent canister is secured to said wheel-like component.

15. A device as claimed in claim 1 wherein the movement of said pawl with respect to said holding plate and wheel-like component causes a vibration to capsules contained in said bottle.
