Abstract: A liner has a thin pliant tubular portion and a stiff base generally conforming to the bottom of a container into which it is inserted and capable of disposing the tubular portion against the walls of the container. The liner is disposed in intimate contact with the container upon the filling of the liner with a liquid material and the free open end of the liner is sealed against the container to maintain the liner in intimate contact therewith and prevent collapse of the liner upon agitation and dispensing of the liquid.
