Abstract

An improved medication timer which encourages economic efficiency by providing an inexpensive restart switch that is useable and reliable with both child-resistant or non-child-resistant medication containers. This apparatus includes a timing-and-alarm unit, an automatic time-measurement restart switch compression switch external to the inner (medication-containing) compartment, and a two-element medication closure with an inner cap element providing the physical and chemical closure and the outer sleeve element providing a means for engaging the inner cap element, retaining the timing-and-alarm unit, and activating the automatic time-measurement restart switch compression switch.

Claims

1. A medication timer for use in conjunction with a medication container having a medication-containing cavity with an access opening provided with outwardly projecting securing means;

wherein, the medication timer comprises;

a removable closure cap including an interior portion having inwardly projecting securing means operatively engageable with the externally projecting securing means on the access opening of the medication container, and an exterior surface

an outer sleeve disposed in a surrounding relationship relative to the exterior surface of said closure cap;

wherein the outer sleeve includes an interior compartment disposed above said closure cap and having an enlarged opening formed therein;

wherein, said sleeve is moveable between a first depressed position wherein the compartment is moved toward the cap and a second retracted position wherein the compartment is moved away from the cap; and

,

a timing unit received within the enlarged opening in said compartment, the timing unit including time-measurement restart switch means activated by movement of the outer sleeve between the retracted position and the depressed position for resetting the timing unit at a predetermined time interval indicating an appropriate time interval for taking medication.

2. The timer of claim 1 wherein the timing unit includes audible alarm means for indicating the expiration of the predetermined time interval.

3. The timer of claim 1 wherein the timing unit includes visual display means for indicating the expiration of the predetermined time interval.

4. The timer of claim 2 wherein the timing unit includes visual display means for indicating the expiration of the predetermined time interval.

5. The timer of claim 4 wherein the compartment is formed of transparent material.

6. The timer of claim 4 wherein the compartment includes a viewing window disposed over the visual display means.

7. The timer of claim 1 wherein the closure cap and outer sleeve are selectively engageable and form a child-proof device.

8. The timer of claim 1 wherein the timing unit includes selection means for changing the predetermined time interval, and wherein the compartment includes access means for providing access to the selection means.

9. The timer of claim 1 wherein the timing unit includes a battery case, and wherein the compartment includes access means for providing access to the battery case.

10. The timer of claim 2 wherein the restart switch means is operably connected to deactivate the alarm.
