Abstract: 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.

Abstract: Provided is a barrel with needle including: a barrel body; and an injection needle, wherein the barrel body has a cylindrical body wall, and an end wall through which the injection needle is inserted, and the inner wall surface of the end wall expands in a direction intersecting the axial direction of the body wall and inclined toward the other opening side of the body wall, with a specific position between an outer circumferential edge and an inner circumferential edge on a proximal end surface of the injection needle serving as a starting point.

Abstract: It is an object of the present invention to provide a syringe which is capable of preventing an accident such that a patient inadvertently sticks her/his hand with an injection needle when improperly performing a needle retracting operation. A sleeve (10) is fitted around a syringe barrel (2) so as to be axially movable from an administration position such that the injection needle (5) projects to a distill side to an accommodation position such that the injection needle (5) is accommodated. A coil spring (16) for biasing the sleeve (10) toward the accommodation position is provided between the sleeve (10) and the syringe barrel (2), and is held in a compressed state in a spring holder (17). The spring holder (17) is disposed in association with the syringe barrel (2) so as to release the coil spring by further pushing the syringe barrel (2) to the distal side after completion of the administration of a liquid drug.

Abstract: A plug member integrally includes a base portion (35a) attached to a plug holder (31) to be mounted on a mouth portion of a container, a plug (34) engaged with an engagement portion (31c) provided in an outlet passage of the plug holder (31), and a resilient connection portion (35b) resiliently connecting the plug (34) to the base portion (35a). Before the first use, the outlet passage is closed with the plug member. In the first use, the container is squeezed to increase the internal pressure of the container. Thus, the plug (34) is disengaged from the engagement portion (31c) by the internal pressure. The outlet passage is thereafter constantly kept open.

Abstract: Provided is a syringe cap including a projection extending in the circumferential direction of a cap body, wherein the projection includes an apex located radially outward of the cap body from the outer circumferential surface of the cap body, a first inclined surface having a starting end located at the apex and having a terminal end located at a position on the side closer to the proximal end of the cap body than the starting end is, and a second inclined surface having a starting end located at the apex and on the outer circumferential surface of the cap body having a terminal end located at a position on the side closer to the distal end of the cap body than the starting end is, on the outer circumferential surface of the cap body, and the shortest distance from the starting end to the terminal end of the first inclined surface is smaller than the shortest distance from the starting end to the terminal end of the second inclined surface.
