Abstract

An apparatus and method for creating a vacuum-sealed package comprising the placement of the item to be vacuum packed in a container; sealing the container, placing a portion of the container in contact with a sealable chamber; sealing the chamber, creating holes in the container, evacuating the desired amount of air from the container and creating a seal between the interior of the container and the holes.

Claims (12)

1. A method for forming a vacuum package comprising

sealing an item in a container to form a standalone sealed container in that the standalone sealed container will remain sealed in the absence of any external sealing mechanism, wherein the sealed container comprises at least one area with two opposing sides;

evacuating the sealed container by making a cut through each of the two sides of the sealed container and evacuating the desired volume of air from the sealed container; and

sealing the evacuated container by forming a seal between the two sides so that the cut in each side is sealed off from the rest of the interior of the container.

2. A method for forming a vacuum package comprising:

placing an item in a container wherein the container is a bag comprising a reclosing mechanism, and wherein the container comprises at least one area with two opposing sides;

closing the reclosing mechanism to form a sealed container containing the item;

evacuating the sealed container by making a cut through each of the two sides of the container and evacuating the desired volume of air from the container; and

sealing the evacuated container by forming a seal between the two sides so that the cut in each side is sealed off from the rest of the interior of the container.

3. The method of claim 2 wherein the seal formed by sealing the evacuated container is a seal that completely surrounds the cut.

4. The method of claim 2 wherein the sealing of the evacuated container is accomplished through a thermal seal.

5. A method for creating a vacuum-sealed package comprising placing an item to be vacuum packed in a container; sealing the container with the item to be vacuum packed inside the container, placing a portion of the container in contact with a sealable chamber after having sealed the container with the item to be vacuum packed inside the container; sealing the chamber after placing a portion of the container in contact with the sealable chamber, creating holes in the container after sealing the chamber, evacuating the desired amount of air from the container after creating holes in the container and creating a seal between the interior of the container and the holes after evacuating the desired amount of air from the container.
