  • Patent number: 5048715
    Abstract: A closure assembly for an open-top container including an adapter ring with a depending groove for engagement about the rim of the container. The adapter ring further includes a pair of integral hinge seats having opposed detents which receive and rotationally position a pair of pivot pins integral with an overlying cover. Each pivot pin includes a detent-received shaft portion for rotational manipulation of cover, and a cam selectively engageable with a second detent in the open position of the cover for retention of the cover. The pin cam, in the corresponding detent recess, provides a second pivot axis for complete disengagement of the cover.

  • Patent number: 4826120
    Abstract: A mounting bracket comprising a horizontal base with a pair of laterally spaced upwardly directed mounting arms terminating in spaced relation above the base in a pair of laterally outwardly formed downwardly directed elongate mounting channels. A pair of lugs are interposed in each channel along the length thereof and cooperate with the channel to define a snap-lock. A pair of oppositely directed support shoulders are integrally formed with the base and provide spaced coplanar support surfaces mounting opposed positioning ribs which cooperatively form a snap-lock retainer including converging forward portions and laterally enlarged rear seating portions. Retaining flanges are integrally formed with the base and depend therefrom into spaced overlying relation to the plane of the shoulder surfaces.
