Waste ink-trapping cartridge

Abstract

Abstract PURPOSE:To prevent the leak of waste ink when drawing a cartridge by a method in which a plastic thin film enclosed bag into which waste ink is to be housed is provided, an air-permeable filter is provided to a part of the bag, and the bag is housed in the cartridge. CONSTITUTION:When waste ink is discarded through a tube 6' into a bag 8 from the tip of a needle 7 by action of a pump, the bag 8 is filled with the waste ink according to the amount of the waste ink, and as the bag 8 expands, air in the container 1' is discharged from an opening 12 to outside. A great amount of air coming in, together with the waste ink, goes out to the outside through an air-permeable filter 15, but not liquid. The filter 15, although not the same according to its air permeability and also to amount of air coming into the waste ink trap, can exhibit its sufficient air deflating function when used in slight part of the waste ink trap in general.
