ABSTRACT:
A liner installation device includes a liner (16) for being disposed in a container (10). A manifold (24) is operable to be disposed at the peripheral opening of the container (10) and be connected to a vacuum source (22) through a hose (26). A retaining member (34) comprised of a retaining bracket (36) and a securing bar (38) operable to be disposed in the container (10). The retaining bracket (36) is disposed along the upper corners of the container (10). The liner (16) is then laid into the bottom of the container (10). After the liner (16) is disposed in the container (10), the peripheral edges thereof are held against the peripheral edges of the container (10). A vacuum is pulled on the spacer between the interior surfaces of the container (10) and the exterior surfaces of the liner (16). After the exterior surfaces of the liner (16) are proximate to the interior surfaces of the container (10 ), the securing bar (38) is disposed in the recess between grooves (44) (46) such that the parallel edges (40) (42) of the securing bar (38) are disposed therein and hold the liner (16) therebetween.
