Abstract: A nestable container or a storable-and-nestable container generally of the open-top, rectangular type, comprises along one of its walls a set-back forming a recess which lies inwardly of the remainder of the wall at a lower portion of the container. The recess is provided with means for holding an identifying card or other indicia, e.g. for disclosing the contents of the container so that the card is undamaged upon interfitting of the containers during nesting.

Abstract: A tubular synthetic-resin body usable as a roadway marker comprises spaced upper and lower tubular parts interconnected by thin webs formed integrally with the upper and lower parts. A middle part of contrasting color lies between these upper and lower parts and has grooves receiving the connecting webs. Such a roadway marker is made by fitting the middle part over a core of a mold, and then injecting synthetic-resin material into the mold around this sleeve so as to form the upper and lower parts and the web.

Abstract: A shipping, storage, and/or display box has a plurality of side walls extending upwardly from the box floor. One of these side walls has an upper portion formed between the respective corners with a window within which may fit a panel. A pair of double-axis hinge elements each have first portion journaled in the one wall adjacent the lower edge of the window for pivoting about a first axis and a second portion journaled in the panel for pivoting about a second axis generally parallel to and offset from the first axis. These hinges let the panel lie flat against the lower portion of the respective side when in the open condition, yet ensure that the entire hinge arrangement will lie inside a plane defined by the outer surface of the respective side when the panel is closed.
