摘要： The present invention provides a barrel with a cap, a pre-filled syringe, and a cap with a connector that are available for both connection-receiving bodies of the Luer lock type and connection-receiving bodies of the slip-in type. The present invention is characterized by including: a connector (3) that is 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 located closer to a proximal end in an axial direction of the barrel (1) than the initial position is, thereby allowing the connector (3) to remain attached to the barrel (1) by being detached from the cap (2) separated from a nozzle (11).

摘要： A multi-chamber syringe 10 which can be manufactured at a low-cost and high-productivity is provided. The syringe 10 includes a generally cylindrical barrel 12, a push member 14 and a plug 16, both of which are disposed to fit the inner side surface 12a of the barrel 12 and slidably on the inner side surface 12a. The plug 16 has a main surface 16a provided with a projection 34 having a top 34a which is eccentric to the main surface 16a. When the push member 14 slides in the direction indicated by Arrow A, the plug 16 comes under pressure from the side on the open end 18. When the projection 34 of the projection 16 makes contact with the choked end 20, the pressure from the side on the open end 18 acts to turn the plug 16 in the direction indicated by Arrow B. This causes a bending deformation in a main body 30 and flanges 32a, 32b of the plug 16, to form a first gap 38 and a second gap 40 between the inner side surface 12a of the barrel 12 and the plug 16.

摘要： Provided is a syringe for injecting a medicine, the syringe including: a barrel having a cylindrical shape with a distal end part and a proximal end part and having an outlet opening in the distal end part for discharging the medicine contained inside the barrel to an outside; and a partitioning device for partitioning a space inside the barrel into a proximal side space and a distal side space, the partitioning device including: a cylindrical housing disposed to come into liquid-tight contact with an inner surface of the barrel; and an inner plug disposed to allow a proximal side space inside the housing and a distal side space inside the housing to be opened and closed so that the proximal side space inside the barrel and the distal side space inside the barrel are brought into or out of communication with each other through an inside of the housing, the housing including an engaging part configured to engage with the inner plug when the proximal side space inside the housing and the distal side space inside the housing are not in communication with each other, the inner plug including an engaged part configured to engage with the engaging part from a proximal side when the proximal side space inside the housing and the distal side space inside the housing are not in communication with each other, and the partitioning device being configured so that, when a pressing force is applied from the proximal side by a piston inserted from the proximal side into the barrel, one of the engaging part and the engaged part is displaced relative to an other one of the engaging part and the engaged part to cross over or ride over the other one and release engagement between the engaging part and the engaged part, thereby allowing the inner plug to have the proximal side space inside the housing and the distal side space inside the housing communicating with each other to achieve communication between the proximal side space inside the barrel and the distal side space inside the barrel.

摘要： An object is to provide a syringe that is capable of preventing a cap from being mounted to a syringe body at an oblique angle. The cap includes an elastic cylindrical body for receiving an injection needle therein and sealing a holding part, and an external cylindrical body for covering the circumference of the elastic cylindrical body and holding the elastic cylindrical body in such a manner as to prevent movement of the elastic cylindrical body. The external cylindrical body includes an opening part having a dimension configured to be larger than the holding part of the syringe body, and a guide part that guides the injection needle toward a certain direction by coming into contact with a part of the syringe body when the injection needle is received inside the elastic cylindrical body.
