Abstract: A container for frangible articles comprising a tray molded in a sheet of polymeric material having a hinge portion separating a bottom portion from a cover portion with the cover portion being pivotable into engagement with the bottom portion to conceal the frangible articles in the container. The bottom portion comprises rows of cavities with each cavity adapted to support a frangible article. The cavities have lugs projecting inwardly and from bottom to top from a main surface of the cavity to support the frangible article while maintaining air gaps between the frangible article and the main surface. Corner cavities are positioned at opposite leading corners of the bottom portion and each have a protective rib oriented toward its respective leading corner and projecting outwardly from the main surface and from bottom to top to provide structural integrity to the opposite leading corners of the container.

Abstract: A method of selectively recycling a specific material involves the use of a DNA taggant detectable in the used material to identify such material for recycling to the originating source of the material to yield focused, selective and cost effective recovery.

Abstract: A stackable tray obtained by vacuum molding of a sheet of plastic material, said tray comprising, in open position: a) a top and a bottom; b) at least one receiving cavity opened upwardly; c) spacing means to keep, in a stack of trays, the top portion and the bottom portion of neighboring trays at distance from each other to thereby prevent interlocking. A stack of said trays and a method using said trays.

Abstract: A stackable tray obtained by vacuum molding of a sheet of plastic material, the tray comprising, in open position: a) a top and a bottom; b) at least one receiving cavity opened upwardly; c) a hinge portion dividing the tray into a cover portion and a base portion; the receiving cavity being at least provided in the base portion; d) spacing members to keep, in a stack of trays, the top portion and the bottom portion of neighboring trays at distance from each other to thereby prevent interlocking therebetween; and e) at least one two-part locking members, each part being provided in the top of the sheet and positioned to engage one into the other when the cover portion is folded over the base portion along the hinge portion to bring the tray into a closed position defining a box. A stack of the trays and a method using the trays are also provided.
