  • Patent number: 6102250
    Abstract: A device for storing and serially dispensing cards, typically those impregnated with a perfumed scent for sampling by a perspective customer. The device stores a number of cards arranged in a substantially vertical stack. The cards are moved to a dispensing point by a spring loaded carriage into a dispensing mechanism which serially removes a leading card from the stack, changes its position to horizontal and ejects it through an opening in the front of the device as a lever is manually depressed.

  • Patent number: 4815612
    Abstract: An improved display device suitable for supporting packaged expendable items, normally for use with a single article of manufacture, such as supplies for a typewriter and the like. The device may be used by supporting it on a horizontal surface, such as a counter, or separated into components for support upon a vertical surface such as a wall. The device includes a plurality of molded rectangular panels having openings for supporting peg board hooks. The panels are interconnected in opposed pairs to form a two-sided display supported in rotatable manner upon a base. An auxiliary upper panel which may carry advertising material is integrally molded therewith. The panels are maintained together by slideably engaged edge members at the sides thereof, and at the bottom thereof by semi-circular projections which are maintained in abutted relation by a retaining ring. A supporting pull penetrates the ring and projections to interconnect the panels with a horizontally oriented base.

  • Patent number: 4777749
    Abstract: An edge lighted display in which light is transmitted through a translucent planar panel to be refracted by the presence of indicia, such as a crayon marking to provide a luminescent appearance. In the disclosed embodiment, the translucent panel which is made of synthetic resinous materials is provided with a thin coating on an outer surface thereof of a harden silicate material, whereby light rays pass in the plane of the junction between the outer surface of the panel and the inner surface of the coating prior to refraction for improved brilliance.
