Abstract

A food storage appliance is provided including a housing containing operative components of the food storage appliance. There is a first heat sealing element disposed on a lower portion of the housing configured to heat seal a first end of a section of food storage container material forming a food storage container unsealed at a second end. A vacuum chamber is disposed in an upper portion of the housing connected to a source of suction. A second heat sealing element is disposed in the upper portion of the housing adjacent to the vacuum chamber configured to heat seal the second end of the food storage container after being inserted into the vacuum chamber and being evacuated by suction from the suction source.

First claim

What is claimed is:

1. A food storage appliance, comprising:
a housing containing operative components of the food storage appliance;
a first heat sealing element on a lower portion of the housing configured to heat seal a first end of a section of food storage container material forming a food storage container unsealed at a second end;
a vacuum chamber disposed in an upper portion of the housing connected to a vacuum-motor-assembly;
a second heat sealing element in the upper portion of the housing disposed adjacent to the vacuum chamber configured to heat seal the second end of the food storage container after being inserted into the vacuum chamber and being evacuated by suction from the vacuum-motor assembly, the second heat sealing element being independently operable relative to the first heat sealing element such that it is operable at the same time as the first heat sealing element;
a transparent lid covering the vacuum chamber movable between an open position for inserting the second end of the food storage container into the vacuum chamber and a closed position for evacuating the food storage container and heat sealing the second end;
at least one latch member on an underside of the lid; and
at least one cylinder having an operative member configured to engage the latch member when the vacuum-motor assembly is energized, the latch member drawing the lid into the closed position and locking the lid against the housing during evacuation of the food storage container or heat sealing of the second end.

2. The food storage appliance of claim 1 , further including:
the at least one cylinder fluidly connected to exhaust tubing of the vacuum-motor assembly to provide pressurized air to the at least one cylinder causing the operative member to engage the latch member and draw the lid into the closed position prior to evacuating the food storage container.

3. The food storage appliance of claim 1 , further including:
a pair of latch members on the underside of the lid on opposing sides of the lid; and
a cylinder associated with each latch member each having an operative member configured to engage the latch member when the vacuum-motor assembly is energized, the latch member drawing the lid into the closed position and locking the lid against opposing ends of the housing prior to evacuation of the food storage container and heat sealing of the second end.

4. The food storage appliance of claim 1 , further including:
a removable drip tray fitted into the vacuum chamber for collecting liquid food dripping during evacuation of the food storage container.

5. The food storage appliance of claim 1 , further including:
an elongated cavity formed in the housing for receiving a roll of food storage container material for supplying a continuous sheet of food storage container material that can be unrolled from the roll in sections for forming multiple food storage containers that are heat sealed by the first heat sealing element on the first end prior to being cut from the roll and heat sealed by the second heat sealing element on the second end after being cut from the roll.

6. The food storage container of claim 1 , further including:
an elongated bumper bar disposed beneath the vacuum chamber on the upper housing which is depressed after the inserting the second end of the food storage container into the vacuum chamber to initiate evacuating the food storage container and heat sealing the second end.

7. The food storage container of claim 6 , further including:
a circuit to delay initiating evacuating the food storage container and heat sealing the second end until after the bumper bar has been depressed and released.

8. A food storage appliance, comprising:
a housing containing operative components of the food storage appliance;
a first heat sealing element on a lower portion of the housing configured to heat seal a first end of a section of food storage container material forming a food storage container unsealed at a second end;
a vacuum chamber disposed in an upper portion of the housing connected to a vacuum-motor-assembly;
a second heat sealing element in the upper portion of the housing disposed adjacent to the vacuum chamber configured to heat seal the second end of the food storage container after being inserted into the vacuum chamber and being evacuated by suction from the vacuum-motor assembly, the second heat sealing element being independently operable relative to the first heat sealing element such that it is operable at the same time as the first heat sealing element;
a cavity being open on at least one end for insertion of the roll of food storage container material, the cavity formed by:
a lower housing assembly having a substantially planar horizontal portion for placement on a surface; and
a substantially planar vertical portion attached perpendicular wise at a lower end to the horizontal portion, the upper housing attached cantilever fashion to an upper end of the vertical portion and extending over the cavity.

9. The food storage appliance of claim 8 , the lower housing assembly further including:
A cutter bar assembly pivotally attached to a front edge of the lower housing assembly, the cutter bar assembly movable from a first position to a second position facilitating positioning of the first end of the section of food storage container material over the first heat sealing element prior to heat sealing and then movable back to the first position for facilitating heat sealing of the first end.

10. The food storage container of claim 9 , further including:
a rotating lever on one end of the cutter bar assembly that is rotated a first time in a first direction after the cutter bar assembly is moved back to the first position configured to lock the cutter bar assembly into the first position to facilitate heat sealing the first end of the section of food storage material, and then rotated in a section direction opposite the first direction after heat sealing the first free end to release the cutter bar assembly from the first position so that the section of container material can be further extended from the lower housing, followed by moving the cutter bar assembly back to the first position and rotating the lever a second time in the first direction to lock the cutter bar assembly in the first position to facilitate cutting the section of food container material from the roll; and
a sliding cutter movable back and forth along an elongated track formed in the cutter bar assembly, the sliding cutter bar having a blade that engages the section of food storage container material as the sliding cutter is moved back and forth along the track after the cutter bar assembly is moved to the first position and locked by rotating the lever in the first direction the second time.

11. The food storage container of claim 10 , further including a switch that is normally open but is closed when the lever is rotated in the first direction automatically energizing the first heat sealing element to heat seal the first end of the section of container material.

12. A food storage appliance, comprising:
a housing;
a vacuum chamber;
a vacuum-motor assembly fluidly connected to the vacuum chamber for providing suction to the vacuum chamber when energized;
a lid movable between an open position and a closed position covering and sealing the vacuum chamber when the vacuum-motor assembly is energized; and
at least one pneumatically activated cylinder connected to exhaust tubing of the vacuum-motor assembly, the cylinder having a sliding rod that is extended when pressurized air from the exhaust tubing is applied to the cylinder, the sliding rod engaging a la
