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.
