  • Patent number: 7004630
    Abstract: A reclosable package has a flexible zipper and a flexible funnel that can be turned inside out to provide a spout for dispensing the package contents. The funnel has a terminal portion that is offset relative to a midplane of the package. Initially, the funnel is tucked inside the filled package in an unopened state. The funnel can be accessed by pulling apart the zipper halves. The consumer must reach inside the open package and pull the funnel inside out. Then the tip of the funnel is snipped, cut or torn to provide a spout for dispensing product. The offset of the opening allows the consumer to better direct the pour of the package contents, while making the bag easier to handle, especially large bags. The funnel itself directs the package contents, especially fine powders, away from the reclosable zipper profiles so that one or both profiles do not become clogged with matter that might interfere with interlocking.

  • Patent number: 6299353
    Abstract: The zipper for a reclosable bag includes a male profile and a female profile. The female profile includes first and second legs extending from a planar base, with a space formed therebetween for insertion of a male profile therein. Apertures are formed in the planar base providing communication between the space between the first and second legs and an opposite side of the planar base. This allows the insertion of the male profile into the female element to urge particles or powder lodged in the space to pass through the apertures to the opposite side of the planar base.
