  • Patent number: 5427260
    Abstract: A tamper-evident dispensing closure is provided with a base suitable for attachment to a container. The base has a deck defining a dispensing orifice and an anchor-receiving opening with an adjacent anchor-retention structure. A lid is provided to close the orifice and defines an aperture spaced from the dispensing orifice when the lid is seated on the base. A tamper-indicating element is provided with an anchor retained in the opening below the deck in the base. The element has a first segment extending from the anchor through the base opening, between the base and lid, and through the lid aperture. A second segment extends from the first segment and is disposed adjacent a portion of the lid to inhibit movement of the lid from the closed position. A first frangible connection joins the first and second segments at the lid aperture. Preferably, a second frangible connection joins the first segment to the anchor at the anchor-receiving opening in the base.
