Vacuum producing appliance

Abstract

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.
