Patent number: 11111061Abstract: A liquid storage bottle includes a nozzle which has an inlet through which a liquid is injected, a cylindrical cap which is mountable on the nozzle to open or close the inlet, a slit valve which is provided in the inlet and includes a plurality of slits intersecting each other, and a sealing unit which seals the inlet when the cap is mounted on the nozzle. The cap includes a protrusion which protrudes from a surface facing the inlet toward the slit valve when the cap is mounted on the nozzle, and a tip portion of the protrusion faces the slit valve at a position separated in a radial direction of the nozzle from an intersection of the plurality of slits in a state where the inlet is sealed by the sealing unit.Type: GrantFiled: March 23, 2020Date of Patent: September 7, 2021Assignee: Canon Kabushiki KaishaInventors: Noriyasu Nagai, Kenta Udagawa, Hiroshi Koshikawa, Hiroki Hayashi, Manabu Ohara, Shoki Takiguchi
