Abstract: A method for sealing an ink cartridge is disclosed. A cover film is bonded to the ink cartridge in such a manner as to cover an ink inlet hole formed in the ink cartridge. An opening is formed in the cover film in such a manner as to communicate with the hole of the ink cartridge. The method includes preparing a seal film and bonding the seal film to the cover film with a bonding strength smaller than the bonding strength of the cover film with respect to the ink cartridge in such a manner that the seal film becomes peelable from the cover film, thereby sealing the opening of the cover film.

Abstract: A piercing method for forming an opening in a cover film welded to an ink cartridge in such a manner as to cover first and second ink inlet holes is provided. The method includes: forming a cut in the cover film in such a manner as to provide a cut piece supported in a cantilever manner in a covering area of the cover film that covers the first and second ink inlet hole; and forming the opening in the cover film by causing the cut piece to hang down in the first and second ink inlet holes.

Abstract: A method for sealing an opening formed in a cover film welded to a fluid retainer at a position corresponding to a covered area of an ink inlet hole. A sealing member, which seals the opening, is a laminated film including a first film and a second film. The method includes preparing the laminated film, placing the laminated film on the fluid container with the first film facing the fluid container in such a manner that the laminated film covers the opening, and sealing the opening with the laminated film by heating the sealing member covering the opening from the side corresponding to the second film to melt the first film.

Abstract: A method for sealing a bore formed in a cover film is disclosed. An ink inlet hole formed in an ink cartridge is covered at a hole covering area of the cover film. The method includes formation of a recess outside the hole covering area by removing a portion of the cover film, mounting a seal film on the cover film in such a manner that the seal film covers the bore, and sealing the bore with the seal film by heating the seal film with the seal film mounted on the cover film and thereby melting a side of the seal film opposed to the cover film.

Abstract: The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduction port for introducing the pressurized fluid to the inside and a liquid delivery port for delivering the liquid to the outside. A detection unit is provided in the container body and outputs an output signal which is changed in accordance with a change in pressure of the liquid in the inside of the container body.

Abstract: Since a bypass flowing passage which communicates with the inside of a bag part not through a second valve mechanism is provided for an outlet part, ink can be filled from the outlet part into the bag part in spite of the existence of the second valve mechanism. Further, after an empty ink pack has been housed in an inner case, the ink is filled into the ink pack. Therefore, when a first seal film is welded to the inner case, since the bag part is not bulky, the ends of the bag part are caught in a cartridge case. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after the ink has filled into the ink pack, contamination of air bubbles into the bag part through the bypass flowing passage is prevented.

Abstract: The present invention is a gas absorption device arranged in a liquid container storing a liquid fed to a liquid consumption apparatus. The device includes a decompressed container having an opening and a flexible film sealing the opening in the state that the decompressed container is internally decompressed. At least a part of a portion having an inner surface which receives the decompressed pressure in the decompressed container and an outer surface which is in contact with the liquid in the liquid container is formed by a gas permeable material through which gas dissolved in the liquid in the liquid container can permeate. According to the present invention, gas dissolved in the liquid stored in the liquid container can be absorbed using a decompressed space and the existence of a decompressed status necessary to absorb gas can be easily examined.

Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after the ink has filled into the ink pack, contamination of air bubbles into the bag part through the bypass flowing passage is prevented.

Abstract: A bypass flowing passage communicating with the inside of a bag part not through a second valve mechanism is provided for an outlet part 12, and ink can be filled from the outlet part into the bag part 11 despite the second valve mechanism V2. After an ink pack is housed in an inner case ink is filled into the ink pack. When a first seal film is welded to the inner case, the ends of the bag part are caught in a cartridge case because the bag part is not bulky. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after ink has filled the ink pack, contaminating of air bubbles into the bag part through the bypass flowing passage is prevented.

Abstract: Since a bypass flowing passage 32 which communicates with the inside of a bag part 11 not through a second valve mechanism V2 is provided for an outlet part 12, ink can be filled from the outlet part 12 into the bag part 11 in spite of the existence of the second valve mechanism V2. Further, after an ink pack that has been yet filled with ink has been housed in an inner case 92, the ink is filled into the ink pack. Therefore, when a first seal film F1 is welded to the inner case 92, since the bag part 11 is not bulky, the ends of the bag part 11 are caught in a cartridge case. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage 32 is blocked after the ink has filled into the ink pack, contamination of air bubbles into the bag part 11 through the bypass flowing passage 32 is prevented.
