Abstract: A corrugated board tray has stacking lugs extending from double thickness side walls. The stacking lug is formed from an integral upward extension of only the outer one of the side wall panels. The lug is folded inwardly and secured to the inside of the side wall. Corresponding slots are formed at the junction of the side wall and the base to receive the stacking lugs of a lower tray. Half-size trays may include stacking lugs and slots formed in the end walls.

Abstract: A container made of double faced corrugated board incorporates a tear tape (10,27) for opening it which is secured to the inside surface of walls (1,2,3,4,22) of the container. The tear tape is arranged to be pulled through one or more lines of weakness (14,23) formed in the outside of the board in alignment with the tear tape, the one or more lines of weakness not extending through the board.

Abstract: A clip type fastener for attachment to a mounting or supporting element, as the handle of a toolbox or toolbox drawer, for wedgingly receiving an article, as a key for the toolbox lock, in accessible position to insert or remove the same relative to a mounting recess in the fastener body portion from which spaced legs extend in directions for selectively and resiliently gripping mounting or support elements, as handles, of different cross-sectional configurations; outer legs being adapted for snap engagement and mounting on the web portion of a formed angle or beam type, as a T-angle, mounting element or handle with an intermediate leg acting as a strut against the web portion for properly positioning the fastener thereon; and with an outer leg and an intermediate leg adapted for snap engagement and mounting on a handle or other supporting element of generally uniform cross-section, as an extruded aluminum element, for properly positioning the fastener thereon.
