Patent Images
1. A nursing container comprising:
- a substantially rigid outer shell;
a co-extensive flexible inner liner selectively adhered to said outer shell and separable therefrom;
a nipple access site defined in said shell and liner;
a nipple assembly sealed to said container at said access site;
said access site being defined by a continuous circumferential fold in said shell and liner tightly capturing said liner to prevent inadvertent delamination of said liner outwardly of said fold upon rupture of said access site.

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.
