Abstract
A method for disposing a waterproof liner in a container includes disposing a bag within the container and attaching the peripheral edges at the opening of the bag to the peripheral edges of the container opening. A negative pressure is then formed in the space between the bag and the inner walls of the container to cause the sides of the liner to move toward the sides of the container and adhere thereto.
