Abstract: A detachable two-part lid for a container wherein oppositely positioned wire members hold the two parts of the lid together when separated from the container and also provide a captured hinging of the lid parts when they are positioned on the container. In a preferred manner, a slot is provided in a guide and a gooseneck portion is provided in the wire members, so as to afford a wire rentention feature when the gooseneck portion is moved outwardly from the slot.

Abstract: An extension collar for a container tray or box which can be readily fitted onto the container and afford varying height extensions for the container. The collar has side members which are first positioned on the top rim of the container and subsequently the end members are attached to the previously positioned collar members by means of projections. The projections have barbed ends positioned either vertically or horizontally for fitting into the previously positioned collar members having a latch arrangement for receiving them. The collar members have flanges for a loose positioning of the collar members on the top rim of the container and are preferably in the form of a flange on one side of the member for engagement with the rim and an opposing hook portion for fitting underneath a projecting wall portion of the rim. The collars can range in height, preferably from one inch to four inches, depending upon the height desired in the extension.

Abstract: A security hinge joint includes a substantially planar, flexible first member, including first and second blind hinge eyes. A second member is pivotable relative to the first member and includes at least one second open hinge eye which lies between the blind hinge eyes. A hinge pin extends through the second open hinge eye and into the first blind hinge eye. The first blind hinge eye wraps around the end of the hinge pin, enclosing the bottom of the pin when the joint is in a closed position, and is interrupted to define a lead-in slot through which the hinge pin can pass. For insertion or removal of the hinge pin, one end of the first member must be flexed out of the plane of the first member.
