Abstract: A liquid container/dispenser including a container body defining a flexible wall for storing a liquid and a tube member having a first end portion placed outside the container body and a second closed end portion placed inside the container body. The tube member has an opening device provided in the second closed end portion of the tube member inside the container body. The second closed end portion can be broken off from the rest of the tube member inside the container body by a force applied through the wall of the container body. The wall of the container body is preferably made from a flexible material so that the wall can be flexibly brought into contact with the tube member inside the container. The liquid container with the novel dispensing system assures the sealed storage of liquid in the container and yet facilitates clean, quick and safe dispensing of the liquid.

Abstract: An ink transfer roller for transferring ink from a re-inking roller to an endless ribbon in ink ribbon cartridges for, for instance, impact printers being contoured on the outer surface. The roller is a cylinder having a central ridge raised in the middle of the outer surface of the roller and a plurality of branch ridges extending from both edges of the central ridge so as to be equally spaced from each other in the circumferential direction for inking the ribbon in proportion to the ratio as the ink is used.

Abstract: An ink refill kit comprising an instruction sheet and an ink cartridge holding box. The ink cartridge holding box is placed in a working area which is located at the center of the instruction sheet, and an instruction area describing steps to be taken for refilling ink printed around the working area. The ink cartridge holding box includes an adhesive material for securely holding the ink cartridge upright and closing the bottom hole of the ink cartridge.

Abstract: A ribbon cartridge for use in impact type printers such as line printers, typewriters an, fie-dot printers. The ribbon cartridge includes a housing having a bottom wall portion, a re-inking assembly provided in a re-inking compartment within the housing for re-inking a ribbon, a ribbon storage compartment for storing the ribbon, and a ribbon drive assembly provided within the housing for advancing the ribbon. The ribbon drive assembly includes a toothed transfer-drive gear assembly and an idler gear assembly for engagement with the toothed transfer-drive gear assembly. In one embodiment of the present invention, the ribbon cartridge has a partition wall separating between the re-inking compartment and the ribbon storage compartment, and the toothed transfer-drive gear assembly has a vertical wall portion defining a part of the partition wall.

Abstract: An improved ribbon feed mechanism having idler and drive roller assemblies, each of which uses a single roller rotatably mounted on a retainer support featuring stripping portions which strip an inked ribbon off the rollers preventing the ribbon from wrapping around the rollers. The feed mechanism feeds the ribbon inside a cassette, cartridge or other container so that the ribbon may be stacked or folded in loops or folds inside the cartridge or container and used for computer printing, dot matrix printing, typewriter printing, or other printing operations. Each of the drive and idler assemblies uses a single roller attached to a shaft which may be removably and rotatably mounted to a retainer support. The single rollers are made out of foam material. The use of a single rather than multiple rollers for the roller assemblies facilities gripping of the ribbon passing between the rollers which results in increased pulling force needed for long ribbons.
