Patent number: 8998394Abstract: There is provided an ink cartridge which is formed from an ink-filled ink pack and a hermetic outer shell case for housing the ink pack and which supplies ink to a recording head by means of application of air pressure to a space between the outer shell case and the ink pack. The outer shell case is formed by coupling an upper case and a lower case together. The ink-filled ink pack is housed in the lower case, and the upper case is laid on the lower case from above. The upper and lower cases are hermetically sealed by vibratory welding or heat welding, thus constituting the ink cartridge.Type: GrantFiled: October 30, 2013Date of Patent: April 7, 2015Assignee: Seiko Epson CorporationInventors: Taku Ishizawa, Toshio Kumagai, Masanori Kamijyo

Patent number: 6220702Abstract: The ink bag is structured as follows: To the respective long side portions (1a, 1b, 2a, 2b) of a rectangular-shaped, thermally fusible first film forming the surface portions (1, 2) of the ink bag, there are attached, by thermal fusion, the long side portions of a rectangular-shaped, thermally fusible second film forming the side surface portions (3, 4) of the ink bag and having lower rigidity than the first film to thereby form a cylindrical body. The one-side short side portions (1c, 2c) of the surface portions of the ink bag are attached together by thermal fusion to form a bag body. An ink supply hole forming member (5) is attached by thermal fusion to the other-side short side portions of the surface portions of the ink bag. In the four corners of the ink bag, there are formed band-shaped connecting portions (6 to 9) each starting from one of the two mutually adjoining sides of the ink bag and reaching the other of the two sides.Type: GrantFiled: December 23, 1999Date of Patent: April 24, 2001Assignee: Seiko Epson CorporationInventors: Masahiro Nakamura, Takeshi Kobayashi, Masanori Kamijyo, Tadatoshi Honzawa, Michinari Tsukahara
