Vacuum assisted method for installing a waterproof liner

Claim 1

A method for installing a liner, comprising: providing a horizontal container having one open end and interior sides with defined interior dimensions to allow loading through the one opening; providing a deflated moisture proof film liner of dimensions slightly in excess of the interior dimensions of the container and having an opening that corresponds to the container opening; disposing the peripheral edges of the opening of the liner adjacent the peripheral edges of the opening of the container and adhering the peripheral edges of the opening of the liner to the peripheral edges of the opening in the container; disposing outlet tubes adjacent the peripheral edges of the opening of the container in communication with the space between the interior of the container and the exterior surfaces of the liner such that the peripheral edges of the opening of the liner provide a vacuum outlet; and providing a blower in communication with the vacuum for removing the air from the space between the liner and the container to create the vacuum; loading material into the interior of the liner; and closing the opening in the liner to seal the loaded material therein.

Claim 2

A method for installing a liner, comprising: providing a horizontal container having one open end and interior sides with defined interior dimensions to allow loading through the one opening; providing a deflated moisture proof film liner of dimensions slightly in excess of the interior dimensions of the container and having an opening that corresponds to the container opening; disposing the peripheral edges of the opening of the liner adjacent the peripheral edges of the opening of the container and adhering the peripheral edges of the opening of the liner to the peripheral edges of the opening in the container; disposing outlet tubes adjacent the peripheral edges of the opening of the container in communication with the space between the interior of the container and the exterior surfaces of the liner such that the peripheral edges of the opening of the liner provide a vacuum outlet; and providing a blower in communication with the vacuum for removing the air from the space between the liner and the container to create the vacuum; loading material into the interior of the liner; and closing the opening in the liner to seal the loaded material therein.

Claim 4

A method for installing a liner, comprising: providing a horizontal container with internal surfaces and an opening for loading from a horizontal surface; providing a waterproof liner having an inner surface and an outer surface with an opening at one end, the opening in the waterproof liner being at least equal to the opening in the container; disposing the waterproof liner in the interior of the container; attaching the peripheral edge of the opening in the waterproof liner to the peripheral edges of the opening in the container to form a seal therewith; disposing a vacuum manifold between the peripheral edge of the waterproof liner and the peripheral edges of the opening in the container; attaching a vacuum source to the vacuum manifold to continually remove air therethrough such that any leaks about the seal from between the peripheral edges of the opening of the waterproof liner and the peripheral edges of the opening of the container are accounted for, the vacuum source causing the exterior surfaces of the waterproof liner to move outward toward the interior surfaces of the container to form an opening in the interior of the waterproof liner; loading material into the interior of the liner; and closing the opening in the liner to seal the loaded material therein.

Claim 5

A method for installing a liner, comprising: providing a horizontal container with internal surfaces and an opening for loading from a horizontal surface; providing a waterproof liner having an inner surface and an outer surface with an opening at one end, the opening in the waterproof liner being at least equal to the opening in the container; disposing the waterproof liner in the interior of the container; attaching the peripheral edge of the opening in the waterproof liner to the peripheral edges of the opening in the container to form a seal therewith; disposing a vacuum manifold between the peripheral edge of the waterproof liner and the peripheral edges of the opening in the container; attaching a vacuum source to the vacuum manifold to continually remove air therethrough such that any leaks about the seal from between the peripheral edges of the opening of the waterproof liner and the peripheral edges of the opening of the container are accounted for, the vacuum source causing the exterior surfaces of the waterproof liner to move outward toward the interior surfaces of the container to form an opening in the interior of the waterproof liner; loading material into the interior of the liner; and closing the opening in the liner to seal the loaded material therein.

Claim 10

A method for installing a liner, comprising: providing a container with internal surfaces and an opening at one end for horizontal loading through the opening; providing a waterproof liner having an inner surface and outer surface with an opening at one end, the opening of the waterproof liner at least equal to the opening in the container and the waterproof liner having dimensions when expanded essentially equal to or exceeding the dimensions of the container such that when opened the waterproof liner will have the exterior surface thereof proximate to the interior surface of the container; disposing the waterproof liner in the interior of the container on the bottom surface thereof; attaching the peripheral edges of the opening in the waterproof liner to the peripheral edges of the opening in the container to form a seal therewith; attaching a vacuum manifold to a portion of the peripheral edges of the opening in the container and between the corresponding peripheral edges of the opening in the waterproof liner to create a vacuum outlet; creating a vacuum in the space between the interior of the container and the exterior of the waterproof liner by attaching a vacuum source to the vacuum outlet to cause a pressure differential across the exterior and interior surfaces of the liner such that the exterior surfaces of the liner move outward toward the interior surfaces of the container and adjacent therewith with the upper surface of the liner being lifted upward, toward the upper interior surface of the container to form an opening in the interior of the waterproof liner; loading material into the interior of the waterproof liner; breaking the seal between the peripheral edges of the opening on the waterproof liner and the opening of the container; and closing the opening in the waterproof liner to seal the loaded material therein.

Claim 11

A method for installing a liner, comprising: providing a container with internal surfaces and an opening at one end for horizontal loading through the opening; providing a waterproof liner having an inner surface and outer surface with an opening at one end, the opening of the waterproof liner at least equal to the opening in the container and the waterproof liner having dimensions when expanded essentially equal to or exceeding the dimensions of the container such that when opened the waterproof liner will have the exterior surface thereof proximate to the interior surface of the container; disposing the waterproof liner in the interior of the container on the bottom surface thereof; attaching the peripheral edges of the opening in the waterproof liner to the peripheral edges of the opening in the container to form a seal therewith; attaching a vacuum manifold to a portion of the peripheral edges of the opening in the container and between the corresponding peripheral edges of the opening in the waterproof liner to create a vacuum outlet; creating a vacuum in the space between the interior of the container and the exterior of the waterproof liner by attaching a vacuum source to the vacuum outlet to cause a pressure differential across the exterior and interior surfaces of the liner such that the exterior surfaces of the liner move outward toward the interior surfaces of the container and adjacent therewith with the upper surface of the liner being lifted upward, toward the upper interior surface of the container to form an opening in the interior of the waterproof liner; loading material into the interior of the waterproof liner; breaking the seal between the peripheral edges of the opening on the waterproof liner and the opening of the container; and closing the opening in the waterproof liner to seal the loaded material therein.
