ABSTRACT:
A package includes a sealed collapsible container of puncturable film material with liquid contents. One portion of the container is formed into a pocket. The container is also provided with structure for attachable receiving a dispenser which is adapted to be secured to the receiving structure. The dispenser may be a cannula with an insert or penetration conduit. When the insert conduit is placed in the pocket and forced to penetrate the innermost portion thereof, the body of the dispenser is secured to the receiving structure of the container. Pressure may be applied to the container and contents to dispense the contents through the attached cannula; and this pressure forces the inner folds of the gusset into progressive sealing engagement with the insert conduit of the cannula to prevent spillage or seepage of the liquid contents.
