Abstract

One embodiment of the present invention is a medicine dispenser with a built-in dispensing schedule. In this embodiment, a cylindrical container with a close-fitting disk-shaped cap having a cylindrical rim includes an inner schedule display, one day-and-time indication of which is displayed to a medicine consumer through an aperture in the cap rim. Features included in the cap, schedule display, and cylindrical container interoperates to ensure that the displayed day-and-time indication is advanced when the cap is removed and replaced. The displayed day-and-time indication is relatively large and clear, to facilitate viewing by vision-impaired users, and the schedule-advancement mechanism is robust and reliable. In addition, the cap and built-in schedule display include features that allow the displayed day-and-time indication to be set to an initial day-and-time indication.

1. A medicine dispenser comprising:

a disc-shaped cap having a cylindrical rim with a schedule-element display aperture, a ratchet wheel, and a number of lugs extending radially inward from a lower edge of the cap;

a disc-shaped schedule-display element, mounted within the cap to form a cap-and-schedule-display assembly, having a cylindrical rim with an outer display surface along which schedule elements are positioned, a ratchet wheel complementary to the ratchet wheel of the cap, one or more grips on an inner surface, and biasing features extending from an inner surface of the cylindrical rim; and

a cylindrical container, onto which the cap-and-schedule-display assembly is mounted, which includes boss features regularly spaced along an outer surface and positioned to interact with the lugs and biasing features to provide child-proof locking of the cap and to advance a displayed schedule element by one and only one element when the cap is removed and reaffixed to the cylindrical container.

2. A medicine dispenser consisting of:

a medicine container;

a schedule display that includes schedule indications, located at evenly spaced schedule-indication positions on the schedule display, that together comprise a dispensing schedule with dispensing-schedule positions; and

a cap, to which the schedule display is mounted, that is removably secured to the medicine container and that includes a schedule-indication-display aperture through which a schedule indication representing a next dispensing event is exposed,

wherein the cap is removed from the medicine container by rotation with respect to the medicine container in a first direction, the cap is re-secured to the medicine container by rotation with respect to the medicine container in a second direction opposite to the first direction, and the schedule-indication exposed through the schedule-indication-display aperture is advanced by one and only one dispensing-schedule position during each dispensing cycle, and

wherein the schedule indication exposed through the schedule-indication-display aperture is advanced only by either completion of a dispensing cycle or by deliberate manual advancement when the cap is removed from the medicine container.

3. The medicine dispenser of claim 2 wherein the schedule indication exposed through the schedule-indication-display aperture is advanced by one dispensing-schedule position, from any initial dispensing-schedule position within the dispensing schedule, during a single dispensing cycle, the dispensing-schedule position advanced to a first position of the dispensing schedule from a last position of the dispensing schedule when the schedule indication in the last position of the dispensing schedule is exposed through the schedule-indication-display aperture at the beginning of the dispensing cycle.

4. The medicine dispenser of claim 2 wherein the cap, schedule display, and medicine container are each single-piece components.

5. The medicine dispenser of claim 2

wherein the medicine container is a cylindrical container having a hollow cylindrical body, a first closed end, and a second open end to which the cap is removably secured;

wherein the cap comprises a disk-shaped portion with a cylindrical wall having a cylindrical axis perpendicular to the disk-shaped portion, the cylindrical wall including the schedule-indication-display aperture; and

wherein the schedule display comprises a disk-shaped portion with a cylindrical wall having a cylindrical axis perpendicular to the disk-shaped portion, the dispensing schedule provided on an outer surface of the cylindrical wall, the schedule display mounted within the cap so that relative rotation of the schedule display with respect to the cap by a fixed rotational angle advances the schedule-indication-display aperture by one position with respect to the dispensing schedule.

6. The medicine dispenser of claim 5

wherein the outer surface of the cylindrical body of the medicine container includes a first number of evenly spaced boss features;

wherein the inner surface of the disk-shaped portion of the cap includes a first ratchet wheel complementary to a second ratchet wheel on the outer surface of the disk-shaped portion of the schedule display;

wherein a second number of lugs protrude inward from the lower portion of the inner surface of the cylindrical wall of the cap;

wherein the inner surface of the disk-shaped portion of the schedule display includes one or more manual-manipulation features; and

wherein a third number of biasing features are evenly spaced along the inner surface of the cylindrical wall of the schedule display.

7. The medicine dispenser of claim 6 wherein, when the cap is pushed down onto the medicine container during securing of the cap to the medicine container, the lugs fit between spaces between the boss features, and when the cap is then rotated in a first direction, the lugs move along the boss features while a portion of the biasing features are hindered from rotation by interaction with leading edges of the boss features, resulting in a relative rotation of the schedule display with respect to the cap that, in turn, advances the schedule-indication-display aperture by one position with respect to the dispensing schedule.

8. The medicine dispenser of claim 6 wherein, when the cap, in an initially secured configuration, is rotated in a second direction, the lugs move along the boss features the portion of the biasing features are not hindered from rotation by the boss features, resulting in no relative rotation of the schedule display with respect to the cap.

9. The medicine dispenser of claim 6 wherein, when the cap is rotated in the first direction, the first and second ratchet wheels do not prevent rotation of the schedule display with respect to the cap whereas, when the cap is rotated in the second direction, the first and second ratchet wheels intermesh to transfer rotational force from the cap to the schedule display.

10. The medicine dispenser of claim 6 wherein the first number is equal to an integer multiple of the second number and the third number is an integer multiple of the first number.

11. The medicine dispenser of claim 6

wherein each of the first and second ratchet wheel includes a fourth number of teeth;

and wherein the fourth number is an integer multiple of the first number.

12. The medicine dispenser of claim 6 wherein, when the cap is in a secured configuration, the lugs are secured within notches of the boss features.

13. The medicine dispenser of claim 12 wherein a central angle of a lateral arc between a leading edge of each boss feature and a trailing edge within the notch of the boss feature is equal to 360 degrees divided by the number of dispensing-schedule positions.

14. A medicine dispenser comprising:

a medicine container;

a schedule display that includes schedule indications, located at evenly spaced schedule-indication positions on the schedule display, that together comprise a dispensing schedule with dispensing-schedule positions; and

a cap, to which the schedule display is mounted, that is removably secured to the medicine container and that includes a schedule-indication-display aperture through which a schedule indication representing a next dispensing event is exposed, the cap removed from the medicine container by rotation with respect to the medicine container in a first direction, re-secured to the medicine container by rotation with respect to the medicine container in a second direction, opposite to the first direction, and the schedule indication exposed through the schedule-indication-display aperture advanced by one and only one dispensing-schedule position during each dispensing cycle from any initial dispensing-schedule position prior to initiation of the dispensing cycle.

15. The medicine dispenser of claim 14 wherein the schedule indication exposed through the schedule-indication-display aperture is capable of advancement with respect to the dispensing schedule only by completion of a dispensing cycle or by deliberate manual advancement when the cap is removed from the medicine container.

16.
