Barrel with cap, pre-filled syringe, and cap with connector

摘要

A barrel with a cap, a pre-filled syringe, and a cap with a connector that accommodate connection-receiving bodies of the Luer lock type and of the slip-in type, are provided. Some versions include: a connector (3) detachably coupled to a cap (2) so as to be separated from the barrel (1) together with the cap (2) when the connector (3) is located at an initial position where the connector (3) is attached to a barrel (1) via the cap (2); and a connector-side engaging part (33) that engages a barrel-side engaging part (13) of the barrel (1) when the connector (3) is located at an attached position that is closer to a proximal end in an axial direction of the barrel (1) than the initial position, allowing the connector (3) to remain attached to the barrel (1) by being detached from the cap (2) separated from a nozzle (11).

主权项

1. A barrel with a cap, comprising:
a tubular barrel having a nozzle at its distal end; a cap to be attached to the nozzle so as to sealingly close the nozzle; and a tubular connector into which the nozzle is inserted, the connector having a threaded portion for threadedly engaging a connection-receiving body to be connected to the nozzle, wherein the connector is detachably coupled to the cap and is separated from the barrel together with the cap when the connector is located at an initial position in which the connector is attached to the barrel via the cap with the nozzle sealingly closed by the cap, and the connector comprises a connector-side engaging part that engages the barrel when the connector is located at an attached position that is located closer to a proximal end in an axial direction of the barrel than the initial position is, thereby allowing the connector to remain attached to the barrel by being detached from the cap separated from the nozzle.
