[0055] A temperature regulating apparatus according to a preferred embodiment of the invention is illustrated in Figures 1-8, and shown generally at reference numeral 10. The temperature regulating apparatus 10 comprises a housing 12 containing a plurality of canisters 21 , 22, 23, 24 containing pressurized gas that can alter the ambient temperature when dispensed. In a preferred embodiment, the gas has a temperature of -25 degrees Fahrenheit. Preferably, each canister 21 , 22, 23, 24 contains a cooling gas, such as carbon dioxide (CO2). Alternatively, the cooling gas can be freon, nitrogen, a fluorocarbon, such as difluoroethane, trifluoroethane or tetrafluoroethane, or other suitable gas.

[0056] In a preferred embodiment, the housing 12 has the shape of a rectangular cuboid and has dimensions of six inches by four inches by two inches. In another preferred embodiment, the housing 12 has dimension of 3.5 inches by 2.5 inches by 1.5 inches. [0057] The carbon dioxide canisters 21 , 22, 23, 24 are positioned within a canister compartment 20. One canister 21 communicates with a terminal end of a tube 30, and the other canisters 22, 23, 24 are connected to the tube 30 via tee valves 31 , 32, 33, as shown in Figures 5 and 6. Carbon dioxide gas from the canisters 21 , 22, 23, 24 travels into the tube 30.

[0058] The apparatus 10 includes a pair of fans 41 , 42, as shown in Figures 1 and 4. One fan 41 is adapted to draw air into the apparatus 10 from outside of the apparatus 10, and the other fan 42 is adapted to blow the air out of the apparatus 10. The intake fan 41 is positioned proximate an intake vent 61 formed in the housing 12. The outlet fan 42 is positioned proximate an outlet vent 62 formed in the housing 12. Air outside of the housing 12 is drawn in by the intake fan 41 through the intake vent 61, and air inside of the housing 12 is expelled through the outlet vent 62 by the outlet fan 42. The walls of the housing 12 can be made of aluminum, or other suitable material. One end 35 of the tube 30 has an opening that communicates with the first carbon dioxide canister 21 and the opposite end of the tube 30 has an opening 37 for the carbon dioxide gas to exit into an area proximate the fans 41 , 42.

[0059] As shown in Figure 1 , the tube 30 is operatively connected to a thermal reed switch 34 that can stop the flow of gas through the tube 30. A temperature sensing device such as a thermal probe 36 is positioned proximate the intake fan 41 , as shown in Figure 4.

[0063] In a preferred embodiment, the apparatus 10 includes a cooling sleeve member 70 positioned intermediate the tube exit 37 and the fans 41 , 42, as shown in Figures 2 and 7. The sleeve member 70 comprises a container filled with a refrigerant gel, such as a formulation of propylene glycol and water. Alternatively, other refrigerant compositions can be used, such as the refrigerant gel compositions described in U.S. Patent No. 4,357,809, which is incorporated herein. A planar support member 72 having vent openings 45 formed therein can be positioned intermediate the sleeve 70 and the fans 41 , 42, as shown in Figures 3, 4 and 6.

[0064] In a preferred embodiment, foam insulation 75 covers the canister compartment 20 and the battery bank 60, as shown in Figure 7. The foam insulation 75 partially covers the tube 30.

[0065] In a method of using the apparatus 10 according to an embodiment of the invention, the apparatus 10 can be positioned inside a container, such as a thermally insulated cooler. The apparatus 10 can be used to cool the interior of the cooler. The intake fan 41 of the apparatus 10 draws in warm air from the interior of the cooler, and the outlet fan 42 blows out cooler air thereby cooling the interior of the cooler. The apparatus 10 can keep food and beverage items stored in the cooler cool for long periods of time without the need for ice. The temperature regulating apparatus 10 is not operatively connected to the cooler and is removable from the cooler without removing any part of the cooler. The apparatus 10 does not alter the form, fit or function of the cooler in which it is positioned.

[0066] Another embodiment of the invention comprises a container apparatus, shown generally at reference numeral 100 in Figures 9 and 10. The container apparatus 100 comprises a container body 112 and the above described temperature regulating apparatus 10 removably positioned within the container body 112. The container body 112 comprises a substantially rectangular base 114, a substantially rectangular sidewall 116 extending upwardly from the base, and a substantially rectangular lid 170 pivotably attached to the upper edge of the sidewall 116 by hinges 171 , 172. As shown in Figures 9 and 10, an opening 174 is formed in the lid 170, and the temperature regulating apparatus 10 can be releasably retained within the opening 174. The apparatus 10 can regulate the ambient temperature within the interior of the container body 112, and keep items stored in the container body 112 cool. The apparatus 10 is not electrically connected to the container body 112, and can be removed from the container body 112 without removing any other components of the container apparatus 100.

[0067] According to a preferred embodiment, the container apparatus 100 can include a second temperature regulating apparatus 10’, which can be positioned within a concave recess 130 formed proximate the center of the base 114, as shown in Figures 11 and 12. The temperature regulating apparatus 10’ can have a circular shape, and the recess 130 can have a circular shape conforming to the temperature regulating apparatus 10’, as shown in Figures 11 and 12. A plurality of suction cups 134 can be attached to the underside of the apparatus 10’ and the base 114 of the container body 112, as shown in Figure 11. The suction cups 134 help to retain the apparatus 10’ in the recess 130 and prevent the apparatus 10’ from coming out of the recess 130. [0068] A container apparatus according to another embodiment of the invention is illustrated in Figures 13 and 14, and shown generally at reference numeral 300. The container apparatus 300 includes a plurality of temperature regulating apparatuses 350. Each temperature regulating apparatus 350 has the same functional components of the above described temperature regulating apparatus 10, but the apparatus 350 has an elongate shape, as shown in Figure 13.

[0069] The container apparatus 300 comprises a container body 312 having an interior surface that is adapted for receiving and releasably maintaining each temperature regulating apparatus 350 therein. The container body 312 can be made of plastic or other suitable material. The container 312 can be made by injection molding or other suitable manufacturing process. The container 312 can be a thermally insulated cooler. [0070] The container 312 can have a substantially rectangular base 314, and a substantially rectangular sidewall 316 extending upwardly from the base 314, as shown in Figures 13 and 14. The sidewall 316 has four sides defining four corners 321 , 322, 323, 324. The sidewall 316 can include an outer wall section 326 and an inner wall section 336, as shown in Figure 13. The surface of the base 314 and the surface of the inner wall section 336 define interior surfaces of the container 312. The top of the inner wall section can be lower than the top of the outer wall section 326, thereby creating a tiered rest platform 338.

[0071] Four substantially concave and elongate recesses 331 , 332, 333, 334 can be formed in the inner wall section 336 proximate the four corners of the sidewall 316, as shown in Figures 13 and 14. The recesses 331 , 332, 333, 334 begin at the top of the inner wall section 336 and extend downwardly to the base 314 of the container 312. [0072] The elongate recesses 331 , 332, 333, 334 in the container 312 are sized and shaped to conform to the size and shape of the temperature regulating apparatus 350, such that each recess 331 , 332, 333, 334 can receive and retain a temperature regulating apparatus 350 therein, as shown in Figures 13 and 14. Preferably, each apparatus 350 has a length approximately equal to the length of the recesses 331 , 332, 333, 334, and has a perimeter slightly less than the effective perimeter of the recesses 331 , 332, 333, 334, such that the apparatus 350 can be inserted into the recesses 331 , 332, 333, 334, as shown in Figures 13 and 14, and retained within the recesses 331 , 332, 333, 334 by frictional engagement. Each apparatus 350 can be positioned within one of the recesses 331 , 332, 333, 334, and when so positioned the apparatus 350 is substantially flush with a non-recessed portion of the interior surface 336 of the container body 312, as shown in Figure 14.

[0073] Each apparatus 350 dispenses cooling gas 360, such as carbon dioxide, into the interior of the container body 312, as shown in Figure 14. When the thermal probe of the apparatus 350 detects that the temperature within the container body 312 has risen above the desired temperature, the motherboard can send a signal causing the apparatus 350 to dispense another blast of cooling gas 360 into the interior area of the container 312.

[0074] Each temperature regulating apparatus 350 can include a touch screen display 390 by which a user can enter data into the motherboard of the apparatus 350. For example, the touch screen display 390 can be used by the user to enter a temperature that the user desires to be maintained within the cooler 300. Alternatively, each apparatus 350 can include keys, buttons or other means for a user to enter data into the motherboard. The user can enter a desired temperature on the touch screen display 390. The microcontroller of the motherboard can be programmed with a non-transitory computer readable storage medium comprising software having programming instructions that, when executed, causes the microcontroller to electronically transmit signals causing the apparatus 350 to dispense cooling gas 360 at timed intervals in order to achieve and maintain the desired temperature that has been entered by the user on the touch screen display 390. Air can be drawn into each apparatus 350 through an intake vent 361. Cooling gas 360 is emitted through vent openings 362 in each apparatus 350.

[0075] Each apparatus 350 includes a power source positioned within the housing of the apparatus 350 that can be operatively connected to the motherboard and the intake and outlet fans. The power source can be a 5000 mAh battery bank that can be recharged via a USB charge port 392. Each apparatus 350 can include an on/off button 394.

[0076] The temperature regulating apparatus 350 is not operatively connected to the container body 312. That is, the apparatus 350 is not electrically connected to the container body 312 and can function independently from the container body 312. As such, each apparatus 350 can be easily removed from the container body 312 when desired. For example, each apparatus 350 can be removed from the container body 312 for recharging, repair or replacement of the apparatus 350. Each apparatus 350 can be easily slid in and out of its respective recess 331 , 332, 333, 334. [0077] According to an embodiment of the invention, the container apparatus 300 can include a light assembly. For example, a light assembly such as the rectangular light assembly shown at reference numeral 355 in Figures 20 and 21 of U.S. Patent No. 10,088,147, which is incorporated herein, can be positioned on the rest platform 338 of the container apparatus 300.

The temperature regulating apparatus 450 is releasably retained within the container body 412.

[0080] The container body 412 can comprise a substantially rectangular base 414 for positioning substantially horizontally on a floor surface, and a substantially rectangular sidewall 416 extending substantially vertically from the base 414. The sidewall 416 has four sides 421 , 422, 423, 424. Two substantially concave and elongate recesses 431 , 432 are formed in the interior surface on opposing sides 401 , 402 of the sidewall 416, as shown in Figure 15. The recesses 431 , 432 define channels beginning at the upper edge 418 of the sidewall 416 and extending downwardly to the base 414 of the container 412, as shown in Figure 15. The channels 431 , 432 extend substantially vertically, and are substantially perpendicular to the container base 414.

[0081] As shown in Figures 15 and 16, the temperature regulating apparatus 450 can be slid into the opposed recessed channels 431 , 432.
