Abstract

An improved device for timely medication administration that attaches to any original container cap and that measures and displays elapsed time in response to opening or closing of said original container cap is disclosed. Physical, chemical and labeled characteristics of the original medication vessel are thus preserved as dispensed. This device includes a timing unit, a compression reset switch and a thermoplastic housing for the above with a resilient, flexible, circumferential wall that permits operation of the enclosed compression reset switch. The thermoplastic housing also features a rigid lower lip that allows adhesive attachment to the original lid.

Claims

1. An add-on medicine dispensing timer cap which can be affixed to an original medicine vial having a vial closure cap comprising:

a timer cap housing having an upper cap wall with an upper rigid portion;

a circumferential wall integral with said upper wall having a lower deformable portion;

a lower attachment surface integral with said lower deformable portion for attaching said cap housing to the vial cap of the medicine vial; and

a timing mechanism carried by said housing and being displaceable relative to said vial cap in a manner that downward force on said rigid portion of said upper wall causes said timing mechanism to be reset and actuated to indicate the instantaneous time elapsed since said timing mechanism was last reset.

2. The device of claim 1 wherein said lower deformable portion of said circumferential wall includes a circumferential wall that flexes when said downward force is exerted upon said upper wall of said housing to deflect said timing mechanism downward so that said compression switch is engaged by one of said vial cap and lower attachment surface of said housing whereby said timing mechanism is reset and actuated.

3. The device of claim 2 wherein said lower attachment surface includes a circumferential attachment surface which extends inwardly from said circumferential wall attachment to said vial cap.

4. The device of claim 3 wherein said attachment surface includes an adhesive layer.

5. The device of claim 2 wherein said flexible, circumferential wall includes a first wall portion and a second wall portion, said first and second wall portions flexing about a flex line so that said upper wall and timing mechanism are displaced downwardly in the direction of said vial cap when pressed upon manually to remove or replace the cap.

6. The device of claim 1 wherein said upper cap wall includes a display portion for viewing a digital readout of said timing mechanism.

7. An add-on medicine dispensing timer cap which can be affixed to an original medicine vial having a vial cap wherein opening and closing of said vial cap on said vial requires a downward vial cap pressure on said vial cap, said timer cap comprising:

a cap housing;

an upper cap wall having a display portion and an upper rigid portion;

a timer mechanism disposed below said upper wall having a time display viewable through said display portion of said upper wall;

a deformable element disposed below said upper wall;

a lower attachment surface for affixing said cap housing to said vial cap;

said timer mechanism having a reset switch actuated by timer reset pressure exerted on said switch through a downward force on said rigid portion of said upper cap wall and resulting deformation of said deformable element; and

said timer reset pressure being generally less than or equal to said vial cap closure pressure so that said timer mechanism is automatically reset upon closure of said vial cap.

8. The device of claim 7, wherein the deformable element is a cellular foam material.

9. The device of claim 7, wherein the lower attachment surface is the bottom of the deformable element and is adapted to attach the cap housing to an upper surface of the vial cap.

10. An add-on timer for a medicine vial having a closure cap, comprising:

(a) a timer housing, having (i) a rigid upper wall, and (ii) a flexible, circumferential wall, attached to the upper wall, wherein the circumferential wall has a lower attachment surface for attaching the housing to the closure cap, and the circumferential wall is sufficiently flexible to allow relative displacement of the upper wall of the housing toward the closure cap, when downward force is applied to the housing;

(b) a timing mechanism, attached to the upper wall of the housing, having (i) means for measuring elapsed time;

(ii) a digital readout to display elapsed time;

(iii) a battery; and

(iv) a compression switch, wherein the compression switch is positioned to be actuated by displacement of the upper wall of the housing relative to the closure cap; and

(c) a means to attach the lower attachment surface of the circumferential wall to the closure cap.

11. The add-on timer of claim 10, wherein the lower attachment surface of the circumferential wall is adapted to attach the housing to the upper surface of the closure cap.

12. The add-on timer of claim 11 wherein the compression switch is positioned on a bottom side of the timing mechanism, and the compression switch is actuated by engaging the upper surface of the closure cap, when the upper wall of the housing is displaced downward.

13. The add-on timer of claim 10, wherein the lower attachment surface of the circumferential wall is a lip, and the means to attach the lower attachment surface of the circumferential wall to the closure cap is an adhesive applied to the lip.

14. The add-on timer of claim 10, wherein the flexible circumferential wall is resilient, and the housing returns to a non-compressed state, when downward force is removed.

15. The add-on timer of claim 10, wherein the circumferential wall is a cellular foam material.

16. The add-on timer of claim 10, wherein the circumferential wall flexes when downward force is applied to the housing.

17. The add-on timer of claim 10, wherein the circumferential wall deforms when downward force is applied to the housing, and the circumferential wall returns to a non-compressed state when downward force is removed.

18. The add-on timer of claim 10, wherein the circumferential wall is comprised of individual spaced elements constructed of a deformable and resilient material.

19. An add-on timer for a medicine vial having a closure cap, comprising:

(a) a timer housing, having (i) an upper wall, and (ii) a flexible, circumferential wall, attached to the upper wall, wherein the circumferential wall has a lower attachment surface for attaching the housing to the closure cap, and the circumferential wall is sufficiently flexible to allow relative displacement of the upper wall of the housing toward the closure cap, when downward force is applied to the housing, and wherein the circumferential wall further comprises a first wall portion and a second wall portion, which are separated by a flex line, and the first and second wall portions incline and flex outward when downward force is applied to the housing;

(b) a timing mechanism, attached to the upper wall of the housing, having (i) means for measuring elapsed time;

(ii) a digital readout to display elapsed time;

(iii) a battery; and

(iv) a compression switch, wherein the compression switch is positioned to be actuated by displacement of the upper wall of the housing relative to the closure cap; and

(c) a means to attach the lower attachment surface of the circumferential wall to the closure cap.

20. The add-on timer of claim 19, wherein the upper wall of the housing is rigid.
