Abstract

A portable cooler container with active temperature control system is provided. The active temperature control system is operated to heat or cool a chamber of a vessel to approach a temperature set point suitable for a medication stored in the cooler container.

Claims

1. A portable cooler container with active temperature control, comprising:

a container body having a chamber configured to receive and hold one or more containers of medicine;

a lid removably coupleable to the container body to access the chamber; and

a temperature control system comprising

one or more thermoelectric elements configured to actively heat or cool at least a portion of the chamber,

one or more batteries,

circuitry configured to control an operation of the one or more thermoelectric elements to heat or cool at least a portion of the chamber to a predetermined temperature or temperature range; and

a display screen disposed on one or both of the container body and the lid, the display screen configured to selectively display shipping information for the portable cooler container.

2. The portable cooler container of claim 1, further comprising a button or touch screen actuatable by a user to automatically switch sender and recipient information on the display screen to facilitate return of the portable cooler container to a sender.

3. The portable cooler container of claim 1, wherein the body comprises an outer peripheral wall and a bottom portion attached to the outer peripheral wall, the inner peripheral wall being spaced relative to the outer peripheral wall to define a gap between the inner peripheral wall and the outer peripheral wall, the base spaced apart from the bottom portion to define a cavity between the base and the bottom portion, the one or more batteries and circuitry at least partially disposed in the cavity.

4. The portable cooler container of claim 3, wherein the one or more thermoelectric elements are housed in the lid, the temperature control system further comprising a first heat sink unit in thermal communication with one side of the one or more thermoelectric elements, a second heat sink unit in thermal communication with an opposite side of the one or more thermoelectric elements, and one or more fans, wherein the one or more fans, first heat sink unit and second heat sink unit are at least partially housed in the lid, the first heat sink configured to heat or cool at least a portion of the chamber.

5. The portable cooler container of claim 1, further comprising one or more sensors configured to sense the one or more parameters of the chamber or temperature control system and to communicate the sensed information to the circuitry.

6. The portable cooler container of claim 5, wherein at least one of the one or more sensors is a temperature sensor configured to sense a temperature in the chamber and to communicate the sensed temperature to the circuitry, the circuitry configured to communicate the sensed temperature data to the cloud-based data storage system or remote electronic device.

7. The portable cooler container of claim 4, further comprising one or more electrical contacts on a rim of the container body configured to contact one or more electrical contacts on the lid when the lid is coupled to the container body so that the circuitry controls the operation of the one or more thermoelectric elements and one or more fans when the lid is coupled to the container body.

8. The portable cooler container of claim 3, wherein the gap is under vacuum.

9. The portable cooler container of claim 1, further comprising a removable tray configured to removably receive the containers of medicine therein and to releasably lock the containers in the tray to inhibit dislodgement of the medicine containers from the tray during shipping of the portable cooler container.

10. The portable cooler container of claim 1, further comprising means for thermally disconnecting the one or more thermoelectric elements from the chamber to inhibit heat transfer between the one or more thermoelectric elements and the chamber.

11. The portable container of claim 1, wherein the display screen is an electrophoretic display screen.

12. A portable cooler container with active temperature control, comprising:

a container body having a chamber configured to receive and hold one or more containers of medicine;

a lid removably coupleable to the container body to access the chamber; and

a temperature control system comprising

one or more thermoelectric elements configured to actively heat or cool at least a portion of the chamber,

one or more batteries,

circuitry configured to control an operation of the one or more thermoelectric elements to heat or cool at least a portion of the chamber to a predetermined temperature or temperature range; and

a display screen disposed on one or both of the container body and the lid, the display screen actuatable to display shipping information for the portable cooler container.

13. The portable cooler container of claim 12, wherein the display screen is automatically actuatable to change the shipping information displayed upon receipt of a signal.

14. The portable cooler container of claim 13, further comprising a button or touch screen manually actuatable by a user to automatically switch sender and recipient information on the display screen to facilitate return of the portable cooler container to a sender.

15. The portable cooler container of claim 12, wherein the body comprises an outer peripheral wall and a bottom portion attached to the outer peripheral wall, the inner peripheral wall being spaced relative to the outer peripheral wall to define a gap between the inner peripheral wall and the outer peripheral wall, the base spaced apart from the bottom portion to define a cavity between the base and the bottom portion, the one or more batteries and circuitry at least partially disposed in the cavity.

16. The portable cooler container of claim 12, wherein the one or more thermoelectric elements are housed in the lid, the temperature control system further comprising a first heat sink unit in thermal communication with one side of the one or more thermoelectric elements, a second heat sink unit in thermal communication with an opposite side of the one or more thermoelectric elements, and one or more fans, wherein the one or more fans, first heat sink unit and second heat sink unit are at least partially housed in the lid, the first heat sink configured to heat or cool at least a portion of the chamber.

17. The portable cooler container of claim 12, further comprising one or more sensors configured to sense the one or more parameters of the chamber or temperature control system and to communicate the sensed information to the circuitry.

18. The portable cooler container of claim 17, wherein at least one of the one or more sensors is a temperature sensor configured to sense a temperature in the chamber and to communicate the sensed temperature to the circuitry, the circuitry configured to communicate the sensed temperature data to the cloud-based data storage system or remote electronic device.

19. The portable cooler container of claim 16, further comprising one or more electrical contacts on a rim of the container body configured to contact one or more electrical contacts on the lid when the lid is coupled to the container body so that the circuitry controls the operation of the one or more thermoelectric elements and one or more fans when the lid is coupled to the container body.

20. The portable cooler container of claim 12, further comprising means for thermally disconnecting the one or more thermoelectric elements from the chamber to inhibit heat transfer between the one or more thermoelectric elements and the chamber.

21. The portable container of claim 12, wherein the display screen is an electrophoretic display screen.
