Abstract: A rectangular container and cover are disclosed. The container and cover have complimentary latching feature. An inner cover skirt is offset inward toward the cover interior at each corner. The offset is sufficient to permit use of a moveable mold tooling to form each of the corners of the cover. This allows full formation of latching hooks extending around the entire interior of the skirt, such that when the cover is placed on the container the cover latching hooks engage with container latching ribs to secure the cover on the container. A tear strip is also disclosed, the removal of which leaves residual flaps at each sidewall intersection and at about the lateral center of each sidewall. A portion of the cover skirt remains affixed to the container when the tear strip is removed.

Abstract: There is disclosed a tamper-evident device for a closure assembly adapted to be applied to a mouth of a container, for example, a neck of a bottle. There has been identified a need for an improved tamper-evident device which does not have any parts which are removed upon initial opening and which are liable to be reattached by counterfeits or the like. Accordingly the present invention provides a tamper-evident device comprising a sleeve member which comprises a first portion associated with a second portion by a frangible portion therebetween, and wherein said first portion is adapted to be applied to a mouth and neck portion of a container, and said second portion is associated with a container closure member, and wherein an initial container opening operation causes said frangible portion to fracture or break such that when the container is reclosed said first and second portions are located in a spaced apart relationship to one another.

Abstract: A container lid having a tamper evident and tamper resistant band formed of a plurality of equally spaced tabs having spurs that engage the rim of a container with latches formed on the spurs. In one embodiment the tamper evident band is unique because it hinges up instead of down and has a plurality of spurs with a stepped edge forming latches with the spurs engaging slots around the periphery of the lid. The reverse action makes the step edges on the spurs on the inside of tabs formed on the tamper resistant strip pull tighter when any attempt is made to pry or remove the lid from a container or cup. The lid also includes an annulus having interior surfaces that provide an excellent seal both inside and outside of the cup when the tamper resistant band is removed.
