Abstract

Multiple embodiments of mechanisms for sensing the opening and closing of pharmaceutical containers are disclosed. In particular, the example sensing mechanisms of the invention trigger an automatic, built-in, electronic dosage reminder and open/close event logging operation while requiring no additional actions or otherwise changed behavior by the patient, in order to increase patient compliance with dosing regimens. Furthermore, certain embodiments of the sensing mechanisms are reliable and sufficiently low cost to be practical for use in commercial product applications. In one embodiment, the sensing mechanism includes two electrical conductors that have no electrical connection therebetween when the closure is not present on the container and a bridge conductor in the closure that provides an electrical connection therebetween when the closure is tightened onto the container. In this example embodiment, the state of the two electrical conductors may be monitored in order to sense a container opening and closing event.

Claims

1. A system for sensing the opening and closing of a pharmaceutical container, the system comprising:

a pharmaceutical container, comprising;

a container body;

a container neck disposed at one end of the container body;

container threads disposed on the container neck;

a container closure removably attached to the container neck via the container threads;

control circuitry integrated within the container body;

indicators integrated within the container body; and

an automatic sensing mechanism integrated within the pharmaceutical container body.

2. The system of claim 1, wherein the automatic sensing mechanism, comprises:

a first conductor disposed along the outside of the container body;

a second conductor disposed along the outside of the container body; and

a bridge conductor disposed on the inside of the container closure,

wherein the bridge conductor provides an electrical connection between the first conductor and second conductor when the container closure is attached to the container neck, and wherein the first conductor, second conductor, and bridge conductor provide a switch function for sensing the presence or absence of the container closure by detecting when an electrical connection exists or not between the first conductor and second conductor via the bridge conductor.

3. The system of claim 1, wherein the control circuitry may be installed in a well formation that is provided in the outside of the container body, such that the control circuitry is not in direct contact with the contents inside of the container body.

4. The system of claim 1, wherein the control circuitry provides control for the automatic sensing mechanism.

5. The system of claim 1, wherein the control circuitry provides a control means and storage means for managing the automatic sensing mechanism.

6. The system of claim 1, wherein the indicators, comprises a plurality of light-emitting diode (LED) devices.

7. The system of claim 6, wherein the indicators, comprise a first indicator, a second indicator, a third indicator, and a fourth indicators, wherein the first indicator represents a “

close container”

LED for prompting a user to install the closure upon pharmaceutical container, the second indicator represents a “

status ok”

LED for indicating that current state of a dosing regimen is satisfactory, the third indicator represents a “

missed dose”

LED for indicating to the user that a dose has been missed, and the fourth indicator represents a “

take prescribed dose”

LED for indicating to the user that it is time to consume his/her prescribed dose of medication.

8. The mechanism of claim 1, wherein the first conductor and the second conductor extend parallel to one another and are spaced a defined distance apart along the perimeter of the container neck.

9. The mechanism of claim 1, wherein the bridge conductor is provided on a thread on the inside of the container closure.

10. The system of claim 1, wherein the automatic sensing mechanism, comprises:

a first conductor disposed along the outside of the container body;

a second conductor disposed along the outside of the container body; and

a micro-switch integrated into the container neck between the first conductor and the second conductor,

wherein the location of the micro-switch on the container neck is such that when the container closure is tightened upon the container neck a thread of the container closure makes physical contact with an actuator of the micro-switch to close the micro-switch thus providing an electrical connection between the first conductor and second conductor when the container closure is attached to the container neck, and wherein the first conductor, second conductor, and micro-switch provide a switch function for sensing the presence or absence of the container closure by detecting when an electrical connection exists or not between the first conductor and second conductor via the micro-switch.

11. The system of claim 1, wherein the automatic sensing mechanism, comprises:

a first conductor disposed along the outside of the container body;

a second conductor disposed along the outside of the container body; and

a compression region formed by flexible insulator materials that are abutted one to another and disposed between the first conductor and second conductor,

wherein the placement of the flexible insulator material is in alignment with one or more threads of the container closure when the container closure is tightened upon the container neck, and wherein when the container closure is tightened upon the container, its threads apply pressure to the compression region which displaces the flexible insulator material where they abut one another thus causing the first conductor to flex toward the second conductor and make electrical contact thereto, forming a switch function for sensing the presence or absence of the container closure by detecting when an electrical connection exists or not between the first conductor and second conductor.

12. The system of claim 1, wherein the automatic sensing mechanism, comprises:

a Hall effect sensor disposed on the outside of the container body; and

a magnet disposed on an edge of the container closure such that it is in close proximity to the Hall effect sensor when the container closure is tightened to the closed position,

wherein, an output voltage of the Hall effect sensor is at certain states based on the presence or absence of a magnetic field generated from the magnet and thus detects the presence or absence of container closure, thus providing a switch function for sensing the presence or absence of the container closure by detecting when a magnetic field is present or absent.

13. A method of sensing the opening and closing of a pharmaceutical container, the method comprising:

providing a pharmaceutical container having an automatic sensing mechanism;

sensing the opening and/or closing of the pharmaceutical container;

triggering the automatic sensing mechanism to automatically generate a dosage reminder signaling a user at dose time via the control circuitry and indicators which are actuated by opening and re-closing of the pharmaceutical container; and

tracking container usage and dosage compliance.
