A heating and cooling apparatus includes a inner container for containing a food product and having a rim and a side wall and a base dome, and an outer container having an open rim and a side wall and a base dome, where the inner container is snugly fitted into the open rim of the outer container and a common lid on the container rims, and the inner container is shorter than the outer container defining a dry gas chamber between the container base domes containing a dry gas and a thermally reactive structure, and where the diameters of the inner container is less than that of the outer container leaving a radial space between the container cylindrical walls defining a humidification liquid chamber containing a humidification liquid, and a sealing member between the dry gas chamber and the humidification liquid chamber.

A portable nested cook-set includes a cook pot having a pot sidewall with a retention projection and defining an upwardly opening pot interior chamber, a press-pot piston having a piston sidewall and a lower end portion defining an upwardly opening piston interior chamber, and a storage container having an exterior portion and a selectively sealable interior storage chamber. The piston sidewall has a sidewall opening and a retention notch positioned to removably receive the retention projection therein. The press-pot piston sidewall is dimensioned to be selectively storable at least partially within the cook pot. The storage container having an exterior portion with a lower portion dimensioned to be selectively storable at least partially within the piston interior chamber. The storage container and the press-pot piston being releasably threaded together.

The present disclosure relates to a soup cup for maintaining a high sealing property. The soup cup includes a cup body; a compartment; an upper cover; a vertical wall; and an oil seal spring. When the upper cover is clamped to the cup body, primary sealing of the soup in the cup body can be completed, and then the sealing rubber film at the bottom of the upper cover can perform secondary sealing on the cup body; and moreover, the oil seal spring is embedded inside the sealing rubber film, and the oil seal spring expands to achieve tertiary sealing, thereby effectively preventing unfirm attachment between the upper cover and the cup body from caused by excessively long time, eliminating heat loss and liquid overflow caused by existence of various gaps, maintaining a high heat retention effect, and simultaneously creating a desirable use feeling for a holder.

A food preparation table includes a housing at least in part defining multiple food pan receiving locations and a cooling air flow path internal of the housing below the food pan receiving locations. A first food pan is positioned within a first one of the food pan receiving locations such that side walls and a bottom wall of the first food pan are within the cooling air flow path, a first one of the side walls of the first food pan includes a plurality of openings therein to permit some cooling air to enter the first food pan and flow in contact with food items therein.
