Title: Holding device for containers
Inventor: WITTIG GARY P
IPC: B65D90/12
Filed: 1987-05-13
Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE       The holding device for containers includes a receptacle member having a capacity which will accommodate a predetermined size range of containers.  A selected container is held in the receptacle member by biasing members that are detachably secured to the receptacle member.  The biasing members include a flap portion that resiliently bears against the container to detent the container in the receptacle.  If a different container is not compatible with the biasing members, a second set of compatible biasing members can be interchanged with the first set.  Since the biasing members are detachably secured to the receptacle member, the receptacle member can be formed of a plastic having one Durometer level and the biasing members can be formed of a plastic material having another Durometer level.  Each Durometer level is selected to fulfill the optimum desired characteristics of the receptacle and biasing members.  The holding device is thus capable of accommodating containers with relatively wide dimensional variations.

Abstract: UNIVERSAL  RIBBON CARTRIDGE FOR HIGH-SPEED PRINTERS     S P E C I F I C A T I O N     The present invention relates to print ribbon delivery systems for printers.  More particularly, the present invention relates to replaceable ribbon cartridges containing a supply of print ribbon (e.g., a reusable fabric or a one-time-use carbon ribbon bearing a print vehicle such as pigments, dyes, etc.) for delivery to the print head of a high-speed printer.     Early high-speed printers and typewriters used separate ribbon spools mounted on different spindles to store unused inked ribbon, deliver ribbon to the printing mechanism, and take up used ribbon.  Ribbon cartridges have now largely replaced the multiple-spool arrangements.     Because a ribbon cartridge contains most of the print ribbon (both used and unused) within the same enclosure, the possibility that the ribbon will contact undesirable objects (e.g., the clothing or skin of the person handling the cartridge, parts of the printing mechanism, or the print surface) is minimized.  Moreover, ribbon replacement is simple with a ribbon cartridge -- the old cartridge is simply disengaged from and lifted out of the printer and a new cartridge is installed in its place (a printer designed to use ribbon cartridges typically defines an
