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 said housing capable of drawing air from a vessel and passing it through said vacuum. A plurality of vessel sealing lids interact with the vacuum producing appliance, said 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 said main housing, said lids having a check valve that allows air to leave said 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 said 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 said vessel being of double walled construction and each said vessel being fitted with said convex conical interface and said check valve so that said vacuum producing appliance can interface with said food or beverage holding vessels and cause a vacuum to be created within said inner and outer walls.
