Abstract: A liquid storage bottle includes a bottle body having a resin-made first cylindrical part at one end, the first cylindrical part having an opening at its front end, and a tubular nozzle for pouring out the liquid contained in the inside of the bottle body by way of the opening, the tubular nozzle having a resin-made second cylindrical part bonded to the bottle body. The inner peripheral surface of the second cylindrical part is welded to the outer peripheral surface of the first cylindrical part. The outer peripheral surface of the first cylindrical part is provided with an annular groove extending in the circumferential direction and the annular groove is made to contain a part of the resin that is molten during the bonding operation.

Abstract: 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.

Abstract: A liquid storage bottle includes a bottle main body, a nozzle having a discharge port through which a liquid stored in the bottle main body is discharged, a cap mountable on the nozzle and a sealing unit sealing the discharge port when the cap is mounted on the nozzle. The sealing unit includes an annular first rib, an annular second rib and an annular third rib. The outer peripheral surface of the first rib is inclined with respect to the axial direction of the nozzle so that a diameter decreases toward a tip portion of the first rib and the inner peripheral surface of the third rib is inclined with respect to the axial direction of the cap so that a diameter increases toward a tip portion of the third rib.

Abstract: A sealing member is applied to the surface of a liquid storage container having a liquid supply port provided so as to be open to a concave space formed on the surface with a gap between the applied sealing member and the liquid supply ports so as to seal the concave space. The liquid supply port has a profile adapted to be inserted into and connected to a connecting portion for supplying liquid to the liquid supply port. A cut score section is formed on the sealing member as including a center point located at the position on the extension from the front end of the liquid supply port in the direction of connecting the liquid supply port to the connecting portion and the cut score section is torn as it is pressed by the connecting portion moving toward the liquid supply port.

Abstract: The ink adhesion surface sides of the plug member removed from the ink jet recording apparatus and the cap removed from the ink replenishment container are faced each other, superposed and attached so that the ink adhesion surfaces are not exposed to the outside.
