Abstract:
1. A release for a container of the type comprising a cylindrical, open top pail with a sidewall having top rim and an integral circumferential rib extending around the outside of the sidewall below the rim and defining a flat rotation plane, and an internally unthreaded closure having an inverted U-shaped peripheral channel receivingly mateable with the top rim of the pail and having a plurality of circumferentially spaced, radially outwardly extending flat bayonets that slidingly rest on the rib, said pail having a circumferential beam extending around and integral with said rib, said beam defining a holder adjacent the rib for receiving a separately molded snap-in latch tab wherein the latch tab comprises: a separately molded open loop flexible plastic body having a floor element, a top element generally parallel to but spaced from the floor element and at least one side element resiliently joining the top element and floor element, the top element having a top surface that is sloped relative to the rib when installed in said holder such that when the latch tab is snapped in the holder, one end of the top element lies above the rotation plane so as to block an edge of a bayonet to interfere with sliding rotation of the closure in a first direction relative to the pail while the other end of the top element is at or below the rotation plane so as not to interfere with rotation of the closure in a direction opposite to the first direction of rotation; and wherein the said at least one side element forms a resilient hinge so that the top element may be depressed toward the floor element to eliminate interference between the edges of the extension tabs of the closure and the latch and allow the closure to rotate to an opening position.
