Abstract
A package for dispensing a liquid product that includes an outer shell having a flexible resilient sidewall, a base wall and a finish surrounding an outlet opening. An inner bag-shaped liner is disposed within the outer shell, and is unattached to the sidewall and the base wall of the outer shell so as to be collapsible with respect to the outer shell as product is dispensed from the liner. A dispensing structure is secured to the finish. An opening in the base wall of the outer shell vents the volume between the shell and the liner to atmosphere. The opening is orifice-sized to prevent rapid egress of air as the container sidewall is squeezed, so that pressure from squeezing the sidewall forces product within the liner out of the outlet opening and the dispensing structure.
