Abstract

The present invention provides a folded ink bag and an ink box. The folded ink bag is used for supplying ink to a printing device, wherein, the folded ink bag comprises a film bag and a plug component. The film bag is used for storing ink. Two sides in the direction of the short edge are respectively provided with a folded side surface part which can bend from the crease to the inner side. The plug component is installed at the front end of the film bag for leading out the ink in the film bag. The film bag is provided with an ink flow path groove which extends to the direction of the long edge of the film bag at the upper surface and / or the lower surface. When the folded side surface parts are folded from the creases, the ink flow path groove is adjusted to the crease of the folded side surface part. Additionally, the folded ink bag with the structure is accommodated in the ink box.

Description

technical field [0001] The present invention relates to a gazette-type ink pack and an ink cartridge used for supplying ink to a printing device such as an inkjet printing device. Background technique [0002] Generally, an ink cartridge includes an ink bag and a rectangular box-shaped cartridge case for accommodating the ink bag. In recent years, as an ink pack of an ink cartridge, a folded ink pack having a relatively high volume ratio (capacity) of the internal space of the cartridge case has been increasingly used. Regarding the shape of the gazette-type ink pack , very common in bread bags and paper bags. [0003] Here, the folding ink bag includes a film bag and a plug member; the above-mentioned film bag is used for storing ink, and is composed of a plurality of flexible films bonded into a bag shape by heat welding; the above-mentioned plug member is arranged on the side of the film bag. The front end is used to lead out the ink in the film bag. In addition, the f...
