  • Patent number: 4860894
    Abstract: A package assembly is disclosed in which base, trays and top cover are formed of hydrophobic materials. The base has skids and guide projections on its upper surface for positioning and restraining each of a plurality of video glass funnels in a layer of funnels on the base. A tray has a like plurality of upwardly extending funnel support components located to coincide with and rest on the upper surface of the funnels in the base layer. Each support component has a bowl-shaped configuration with an upper surface for supporting the larger open end of a funnel in a layer of funnels on top of the tray. Multiple layers of funnels are separated and supported by the trays. The top cover protects the uppermost layer of funnels and permits tying of the assembly into an integral unit through the use of encircling strapping bands, shrink wrap techniques, or the like.
