Abstract
Abstract A container is disclosed having a semirigid or rigid outer shell and a co-extensive flexible inner liner which is weakly or temporarily adhered to the shell to permit more convenient manufacturing of the container, and yet is collapsible to permit dispensing of the contents without displacement air. The liner may be weakly adhered to the shell by a low tensile strength adhesive although natural adherence or static electric attraction may also be used. Alternatively, a degradable adhesive may be used which holds the liner and shell together during assembly, but weakens to a point below the threshold of release between the shell and liner prior to the time of use. The container is particularly useful as a nursing container for feeding infants.
