  • Patent number: 7694837
    Abstract: A tamper evident container lid is provided that includes a lid body configured to cover the opening of a base container having a top rim. The lid body has a skirt extending therefrom. The skirt has an annular score line and an annular fold line extending therearound. An outer band of the skirt extends between the score line and the fold line, and an inner band is folded inwardly to be in opposing relation to the outer band and extends upwardly from the fold line to an upper free edge. When the container lid is sufficiently applied to the base container such that the free edge slides downwardly past a top rim of the container, achieving a proper closure, an attempt to remove the lid will cause a plurality of sections of the inner band to engage the top rim and impede removal of the lid from the base container.

  • Patent number: 7631776
    Abstract: A container clearly indicates that it has been opened after a store clerk loads food into the base of the container and closes a covering of the container onto the base. The covering (16) includes a peripheral cover portion (22) that becomes fixed to a peripheral base portion (32) when the clerk initially closes the container. To thereafter open the container, a person forcefully lifts a tab (30) on the covering to tear the covering along a long tear line (26) that separates the peripheral cover portion (22) from a lid (24) formed by a radially inner covering portion. The base (12) is fixed to the peripheral covering portion (22), and together they form a base device (40). After the lid has been torn free of the peripheral covering portion, the lid can be closed and latched to the base device and then can be easily opened again.

  • Patent number: 7628283
    Abstract: A tamper-indicating child-resistant package includes a container having a cylindrical finish with at least one external thread segment, a manually deflectable release element externally cantilevered from the finish, and a tear band frangibly connected to the finish and having an upstanding locking lug. A closure has a skirt with at least one internal thread segment for mating engagement with the external thread segment on the container finish, a first lock element on the skirt for engagement with the manually deflectable release element and second lock element on the skirt for engagement with the locking lug on the tear band. Engagement between the second lock element on the closure skirt and the locking lug on the tear band prevents unthreading of the closure from the container finish until the tear band is frangibly removed from the finish, whereupon deflection of the manually deflectable release element releases the closure for unthreading from the finish.
