Vacuum producing appliance and associated food and beverage holding
vessels, the vacuum producing appliance with a hollow housing, the housing
enclosing a vacuum pump, a pressure switch, a vacuum holding tank, a
solenoid valve, a power switch, and associated tubing to attach the
components to each other. A conical shaped concavity built into the bottom
of the housing capable of drawing air from a vessel and passing it through
the vacuum. A plurality of vessel sealing lids interact with the vacuum
producing appliance, the lids having a convex conical shape at their top
surface that can interface in an air tight way with a mating concave
conical shape located in the main housing the lids having a check valve
that allows air to leave the lid but not reenter it. The lids are capable
of interfacing in an air tight way with the mouth of a jar, bottle, can or
the like so that a vacuum can be drawn in the jar, bottle or can. A
plurality of unique food or beverage holding vessels such as a serving
tray, a tumbler, a soup bowl, an ice cream bowl or the like, each vessel
being of double walled construction and each vessel being fitted with said
convex conical interface and the check valve so that the vacuum producing
appliance can interface with the food or beverage holding vessels and
cause a vacuum to be created within the inner and outer walls.
