## Abstract

An inventive vacuum storage container for long term storage of perishable and non-perishable items, incorporating a pump, power supply, controller, sensor, top cover, expandable seal, pressure sensor and base plate. The controller activates the pump based on signals from said sensor to maintain a vacuum state within an interior vacuum chamber formed by said top cover, expandable seal, and base plate. The container is configured to effectively maintain vacuum pressure by activating a pump when the lack of vacuum pressure is indicated.

## Claims

### Claim 1

A vacuum storage container for storing perishable items comprising:
a top cover with a top surface and one or more side walls extending from said top surface, a valve placed upon the top surface;
a base plate having a top surface, a bottom surface, and one or more side walls and comprising;
a vacuum pump for creating a vacuum within a vacuum chamber formed within a cavity formed by the top cover and base plate;
a groove placed along the top surface of the base plate;
an expandable seal placed within said groove for forming a seal against the bottom edge of said one or more side walls of said top cover;
a power supply for providing power to said pump;
a sensor mechanism for detecting pressure levels within said vacuum chamber;
a controller for automatically said pump to maintain a vacuum within said vacuum chamber;
a switch for activating said controller to maintain the vacuum within said vacuum chamber.

### Claim 2 (depends on 1)

The vacuum storage container of claim 1, wherein said power supply is provided by an electrical cord.

### Claim 3 (depends on 1)

The vacuum storage container of claim 1, wherein said power supply is provided by one or more batteries contained within a battery compartment within said base plate.

### Claim 4 (depends on 1)

The vacuum storage container of claim 1, wherein said top surface of said base plate is rectangular and said top surface of said top cover posses four side walls extending laterally from said to surface being rectangular.

### Claim 5 (depends on 1)

The vacuum storage container of claim 1, where said top surface of said base plate is circular and said top surface of said top cover is circular and possesses a side wall which extends laterally from said top surface of said top cover.

### Claim 6 (depends on 1)

The vacuum storage container of claim 1, wherein the sensor comprises:
a diaphragm placed between the vacuum chamber and the exterior of the vacuum chamber;
a second switch placed adjacent to the diagram, so that when the vacuum chamber has reached the desired vacuum level, the diaphragm makes contact with said second switch, deactivating said pump.

### Claim 7 (depends on 1)

The vacuum storage container of claim 1, wherein the sensor comprises one of the following: a potentiometric pressure sensor, indictive pressure sensor, capacitive pressure sensor, piezoelectric pressure sensor, strain gage, or variable reluctance pressure sensor.

### Claim 8 (depends on 1)

The vacuum storage container of claim 1, wherein said base plate further includes one or more clamps placed on the exterior of said one or more side walls that, when engaged, lock said top cover to said base plate.
