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 ### Claim 1 A portable cooler container with active temperature control, comprising: a container body having a vacuum insulated vessel with a chamber configured to receive and hold one or more medicine injector pens, the chamber defined at least in part by an inner peripheral wall of the vacuum insulated vessel; a lid operable to access the chamber; and a temperature control system comprising one or more thermoelectric elements in thermal communication with at least a portion of the chamber via a heat sink having a first portion in thermal communication with the one or more thermoelectric elements and disposed outside the vacuum insulated vessel, a second portion in thermal communication with the inner peripheral wall and at least partially disposed inside a gap between the inner peripheral wall and an outer peripheral wall of the vacuum insulated vessel, and a bridge portion that interconnects the first portion and the second portion of the heat sink, one or more power storage elements, and circuitry configured to control the one or more thermoelectric elements to heat or cool at least a portion of the chamber to a predetermined temperature or temperature range. ### Claim 2 (depends on 1) The container of claim 1, wherein the first portion of the heat sink unit is in thermal communication with one side of the one or more thermoelectric elements and a second heat sink unit is in thermal communication with an opposite side of the one or more thermoelectric elements, and wherein one or more fans, the heat sink unit and the second heat sink unit are at least partially housed in a channel laterally spaced from the chamber. ### Claim 3 (depends on 1) The container of claim 1, further comprising one or more sensors configured to sense one or more parameters of the chamber and to communicate the sensed parameters to the circuitry. ### Claim 4 (depends on 1) The container of claim 1, further comprising a user interface configured to display information indicative of a temperature in the chamber, an ambient temperature, or a charge level of the one or more power storage elements. ### Claim 5 (depends on 1) The container of claim 1, wherein the chamber comprises two spaced a part chambers, each chamber sized to receive one medicine injector pen. ### Claim 6 (depends on 2) The container of claim 2, wherein the one or more fans in the channel are operable to draw air through one or more air intake vents, to flow said air over the second heat sink to dissipate heat from the second heat sink, and to then flow said air through one or more exhaust vents. ### Claim 7 (depends on 1) The container of claim 1, wherein the first portion and the second portion of the heat sink extend substantially parallel to each other, and wherein the bridge portion extends substantially perpendicular to the first portion and the second portion of the heat sink. ### Claim 8 (depends on 1) The container of claim 1, wherein the second portion of the heat sink is longer than the first portion of the heat sink. ### Claim 9 A portable cooler container with active temperature control, comprising: a container body having a vacuum insulated vessel with a chamber configured to receive and hold one or more medicine injector pens, the chamber defined at least in part by an inner peripheral wall of the vacuum insulated vessel; a lid operable by a user to access the chamber; and a temperature control system comprising one or more thermoelectric elements in thermal communication with at least a portion of the chamber via a heat sink having a first portion in thermal communication with the one or more thermoelectric elements and disposed outside the vacuum insulated vessel, a second portion in thermal communication with the inner peripheral wall and disposed inside the vacuum insulated vessel, and a bridge portion that interconnects the first portion and the second portion of the heat sink, and circuitry configured to control the one or more thermoelectric elements to heat or cool at least a portion of the chamber to a predetermined temperature or temperature range. ### Claim 10 (depends on 9) The container of claim 9, wherein the first portion of the heat sink unit is in thermal communication with one side of the one or more thermoelectric elements and a second heat sink unit is in thermal communication with an opposite side of the one or more thermoelectric elements, and wherein one or more fans, the heat sink unit and the second heat sink unit are at least partially housed in a channel laterally spaced from the chamber. ### Claim 11 (depends on 10) The container of claim 10, wherein the one or more fans in the channel are operable to draw air through one or more air intake vents, to flow said air over the second heat sink to dissipate heat from the second heat sink, and to then flow said air through one or more exhaust vents. ### Claim 12 (depends on 9) The container of claim 9, wherein the first portion and the second portion of the heat sink extend substantially parallel to each other, and wherein the bridge portion extends substantially perpendicular to the first portion and the second portion of the heat sink. ### Claim 13 (depends on 9) The container of claim 9, further comprising one or more temperature sensors configured to sense a temperature in the chamber and to communicate the sensed temperature to the circuitry. ### Claim 14 (depends on 9) The container of claim 9, wherein the second portion of the heat sink is longer than the first portion of the heat sink. ### Claim 15 (depends on 9) The container of claim 9, further comprising a visual display on the lid that displays the sensed temperature in the chamber, a temperature of the first heat sink, an ambient temperature, a charge level or percentage for the one or more batteries, or an amount of time left before power from the one or more batteries runs out. ### Claim 16 (depends on 9) The container of claim 9, wherein the chamber comprises two spaced apart chambers, each chamber sized to receive one medicine injector pen.
