A refrigerating assembly temporarily stores an item at a first temperature lower than an ambient temperature. A container receives the item and a shell is adapted for removably receiving the container therein. The container has a sidewall having a cavity therein containing an amount of a refrigerant medium having a second temperature lower than the ambient temperature for temporarily maintaining the item received in the container at the first temperature. The shell has an outer surface which is at the ambient temperature and an inner surface which has a layer of thermally insulating material mounted thereon for thermally insulating the shell from the container, thereby maintaining the outer surface at the ambient temperature.

1. A refrigerating assembly comprising: a container comprising a container sidewall having a container inner surface for receiving an item thereon and a container outer surface, the container sidewall further having therein defined a cavity containing an amount of a refrigerant medium having a second temperature lower than an ambient temperature, the cavity being in thermal connection with the container inner surface for temporarily maintaining the item at a first temperature when the item is received on the container inner surface, the container sidewall further having a closed end and an open end defining an opening for selectively placing the item in the container and removing the item from the container, the open end having a peripheral edge defining a rim of the container; anda shell adapted for removably receiving the container therein, the shell comprising a shell sidewall having a shell inner surface and a shell outer surface, the shell outer surface being at the ambient temperature, the shell inner surface having a layer of thermally insulating material mounted thereon for thermally insulating the shell from the container when the container is removably received in the shell, thereby maintaining the shell outer surface at the ambient temperature when the container is received in the shell, the shell sidewall further having a closed end and an open end defining an opening for selectively placing the container in the shell and removing the container from the shell, the open end having a peripheral edge defining a rim of the shell, wherein the shell is adapted to cover at least part of the container outer surface when the container is received in the shell; andattachment means for removably attaching the container to the shell when the container is received in the shell, the attachment means comprising:a first peripheral flange extending inwardly from the rim of the container;an opposed second peripheral flange extending outwardly from the rim of the shell; anda fastening element for removably engaging the first and second peripheral flanges to thereby removably attach the container to the shell. 2. The refrigerant assembly as claimed in claim 1, wherein the fastening element comprises a fastening ring having an annular channel defined therein, the annular channel comprising a first channel portion sized and shaped to receive the first peripheral flange and a second channel portion sized and shaped to receive the second peripheral flange. 3. The refrigerant assembly as claimed in claim 2, wherein the fastening ring is manufactured from a resilient material for engaging the first and second peripheral flanges in snap engagement. 4. The refrigerant assembly as claimed in claim 2, wherein each of the first and second peripheral flanges has a square cross-section and each of the first and second channel portions has a corresponding square cross-section. 5. The refrigerant assembly as claimed in claim 2, wherein each of the first and second peripheral flanges has a semicircular cross-section and each of the first and second channel portions has a corresponding semicircular cross-section. 6. The refrigerant assembly as claimed in claim 3, wherein the resilient material is a thermoplastic selected from a group consisting of acrylonitrile butadiene styrene and polyvinyl chloride. 7. The refrigerating assembly as claimed in claim 1, wherein the container comprises a flat bottom portion for enabling the container to rest on a flat surface while keeping the opening of the container facing upwardly. 8. The refrigerating assembly as claimed in claim 1, wherein the container sidewall comprises a relief opening defined on one of the container inner surface and the container outer surface for allowing communication between the cavity and the environment such that pressure inside the cavity is maintained equal to an ambient pressure. 9. The refrigerating assembly as claimed in claim 1, wherein the container and the shell are complementary in shape for enabling the container outer surface to rest against the layer of thermally insulating material. 10. The refrigerating assembly as claimed in claim 1, wherein the refrigerant medium comprises a refrigerant gel.
