  • Sterile bag pad
    Patent number: 4006823
    Abstract: A pad of sterile bags wherein each bag is made of flexible thermoplastic sheets. The bags are heat-fused together along the open edge to provide a book-like pad. The weld forms a binding for the individual bags, which are without perforation, and it also forms a solid margin for gripping and handling and provides a line of weakness along which the bags may be separated for use. When a bag is thus separated from the pad it is also opened.

  • Flexible package with counter-pressure dispenser
    Patent number: 3991912
    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.
