  • Patent number: 5407094
    Abstract: A transparent display article dispenser, includes spaced front and rear walls and spaced side walls integral with the front and rear walls to define a vertical chute having open upper and lower ends. The front wall includes a first horizontal retainer flange projecting into the interior of the passageway at a lower end of the chute. The rear wall includes a second horizontal retainer flange projecting towards the first retainer flange and being spaced below the first retainer flange a distance in excess of the height of the article being dispensed. An opening is formed within the front wall below the first retainer flange for removal of an article resting on the second retainer flange. An elongated removable see-through tubular cartridge sized smaller in cross-section than the chute passageway and being configured to that passageway has a lower end inserted within the chute passageway and stores articles to be dispensed in a serial, abutting fashion.

  • Patent number: 4897030
    Abstract: A flat stock strip of thermoplastic material is passed through a heating station in contact with the edges of longitudinally oriented heated knife blades to heat soften the stock strip along narrow longitudinal lines to define localized fold lines for the stock strip. The strip is fed sequentially through a prebending device and a chilled forming die to set the reformed strip at the fold lines. Preferably the knife blades and any strip contact surfaces of the prebending device and the chilled forming die are PTFE covered to eliminate scratching of the thermoplastic stock strip material during heating, reforming and cooling.
