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.

Abstract: A desk organizer or the like includes a plurality of vertically stackable trays having partitions formed therein for storing articles of various sizes and shapes. Each tray has a hollow upright center post which is received within the center post of the tray positioned immediately on top of it. The posts have apertures formed in their distal ends and are so dimensioned that as the organizer is fully assembled each aperture is in closely spaced relation to the respective apertures in the posts of adjacent trays. When it is desired to manually separate particular trays to gain access to certain contents of the organizer, the user may insert the index finger of a single hand into the apertures and grip the desired number of posts, which allows one or more trays to be lifted and separated from the tray to which access is sought. A cover is provided with a knob-like projection having an aperture formed therein so that the cover may be gripped in a manner similar to the manner in which the trays are gripped.
