  • Patent number: 6902170
    Abstract: The present invention is a gasket that is capable of venting gas from a positive pressure gas generating system in a package, such as a bottle or a container. In so doing, the gasket prevents the liquid contained within the package from leaking out. The gasket has a core that is impermeable to liquids, with a first side and a second side opposite the first side. A first outer layer is connected to the first side and a second outer layer is connected to the second side. The first outer layer and the second outer layer are made of a gas permeable membrane. Furthermore, the present invention provides a method of venting gas from the package. The method includes securing a closure fitting shaped to form a seal to an opening of a package. The seal contains a gasket of the present invention capable of venting gases while preventing liquid from leaking therefrom.

  • Patent number: 6123222
    Abstract: There is provided a system for dispensing a plurality of nurser liners one at a time. The system includes a dispenser having a bottom wall with an edge that defines a flap, and a plurality of nurser liners stacked in a nesting arrangement. The flap is adapted to move from a first position to a second position in which the flap exposes an aperture in the bottom wall. Each one of the plurality of nurser liners has a single open end, and the open end has a flexible rim with a diameter greater than that of the aperture. The plurality of nurser liners are positioned so that the rims are adjacent the aperture with a lowermost one of the plurality of nurser liners abutting the edge. Accordingly, the edge acts as a dual-sided guide for deflecting the rim inward of the lowermost nurser liner as the rim passes through the aperture, and restricts the remainder of the plurality of nurser liners from moving with the lowermost nurser liner out of the dispenser to overcome friction forces caused by the nesting arrangement.
