Abstract
The liquid ejection apparatus is capable of reducing the increase of the viscosity of a liquid due to evaporation of the liquid and also for reducing the quantity of the atmospheric air dissolving into the ink. A liquid seal used for a liquid ejection apparatus which performs recording by ejecting a liquid, at least a part of the liquid seal is formed from a layer compound mixture material including a high molecular compound and an inorganic layer compound. The liquid seal seals the liquid. For example, the liquid seal is an ink cartridge accommodating the liquid therein, or an ink guide member for supplying the ink in the ink cartridge to a recording head unit.
Claims11
A liquid seal for use in a liquid cartridge, comprising at least a part which is formed from a layer compound mixture material including a high molecular compound and an inorganic layer compound, the liquid seal sealing the liquid, a direction of said inorganic layer compound being approximately perpendicular to a direction that ink solvent and atmospheric air pass through the liquid seal.
A liquid sealing film at least a part of which is welded to a liquid cartridge, comprising:
- a welding film which is welded to the part of the liquid cartridge;
- a mixture film which is formed from a layer compound mixture material including a high molecular compound and an inorganic layer compound, and
- a heat-resistant film which has a soflening point higher than that of said welding film,
- wherein said welding film, said mixture film and said heat-resistant film are arranged in the above order from a side to be welded to the liquid cartridge.
