ABSTRACT:
A multilayer plastic container for use with either a positive or negative pressure dispensing system, the container having an integral body with an inner layer which readily separates from an outer layer and collapses to dispense a product from the container. The container is formed by blow-molding a multilayer preform, and a bottom aperture is formed in the container for injecting air to separate the inner layer from the outer layer. Preferably, the inner layer is predelaminated during manufacture to facilitate its later separation during use. In the case of vacuum dispening, air inlet vent holes are preferably formed at the points of maximum deformation to prevent collapse of the outer layer.
