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, 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 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 said vessel being fitted with the 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.

1. Vacuum producing appliance and associated food and beverage holding vessels, said vacuum producing appliance comprising: a hollow housing; said housing enclosing a vacuum pump, a pressure switch, a vacuum holding tank, a solenoid valve, a power switch, and associated tubing to attach said components to each other; said vacuum pump turned on by said power switch and turned off by said pressure switch when said vacuum holding tank has reached the proper vacuum level; said pressure switch activating said solenoid valve thereby sealing in said vacuum in said vacuum holding tank; an electrical line cord and plug that supplies power to said vacuum pump; 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; 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; said lids having a vacuum relief valve located on their top surface that can be operated by the user to relieve the vacuum within a vessel located below said lid; said lids having a rigid conical portion built into its lower surface; said lower conical portion having a soft rubber covering around its circumference; said rubber portion capable of interfacing in an air tight way with the mouth of a jar, bottle, or can so that a vacuum can be drawn in said jar, bottle or can; said lids having a variety of diameters of said lower conical portion to allow said conical portion to fit a variety of diameters of food or beverage holding vessels such as a small diameter for a wine bottle, or a large diameter for a larger Ball jar; and a plurality of unique food or beverage holding vessels such as a serving tray, a tumbler, a soup bowl, or an ice cream bowl, 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 containing vessels and cause a vacuum to be created within said inner and outer walls, said vacuum acting as an insulating means for said food containing vessel..
