Abstract: A tamper-evident label for a carton having one flap or two opposing flaps includes a pair of end portions each having adhesive or other means for fastening to span the edge of one flap or opposing flaps of the carton. A central area between the end portions defines one or more strips which overlie an edge of one or both flaps. The central area defining the strips is unadhereable to the flaps and are in a condition such that, upon cutting therethrough to form ends on said strips, the ends will be displaced from the strip ends on the opposite sides of the cut.

Abstract: A composite sheet having the capability of having embossed therein a holographic image or diffraction grating image has a structure of multiple layers including a plastic film carrier, lacquer, metal and, optionally, a lacquer overlay. It may be adhered to a substrate without the necessity of removing the plastic film carrier and may have a holographic image embossed therein during the step of adhering or in a separate operation at a different time and may have printing applied to the layer of metal or to the lacquer overlay.

Abstract: Sumps are mounted on manway fittings of underground tanks, and all piping runs are routed through a sump. Underground portions of pipes between a sump and a point above ground are provided with a double wall. Filling spills and leakage from pipes into the environment are thereby generally prevented.
