Abstract
A container is disclosed having a semi-rigid or rigid shell, a co-extensive flexible liner weakly or temporarily adhered to the shell and an access site defined in the container wall to which an access assembly may be attached. The access site is preferably defined by an annular fold in the container wall which tightly captures the liner to provide a mechanical peripheral seal between the shell and liner around the access site to prevent leakage of liquid, into the area between the shell and liner. The container is particularly useful as a nursing container, including a nipple access site with an attached nipple assembly.
