Abstract

A syringe assembly (22) of a prefilled syringe (12) comprises a syringe cap (10). A tapered portion (86) of a second tubular portion (102) that constitutes the cap (10) has, on the outer peripheral surface of the tapered portion (86), a plurality of step portions (88) continuously arranged along the central axis (Ax) of a cover member (36) so that the amount of protrusion of the tapered portion (86) increases in a stepwise manner from the outer peripheral surface of an annular peripheral wall portion (80) toward the vicinity of the outer edge of an aperture (58) in a first tubular portion (100).

Description

technical field [0001] The present invention relates to a syringe cap, a syringe assembly, and a prefilled syringe that can be attached to and detached from a syringe body that includes a body portion capable of accommodating medicines therein, and a body portion extending from the front end portion of the body portion toward the front end. A nozzle part that protrudes and has a drug discharge port at the front end. Background technique [0002] For example, International Publication No. 2018 / 061948 discloses a cap for a syringe including a cap main body and a cylindrical cover member covering the cap main body. The cap main body has an attachment portion that can be attached to the nozzle portion of the syringe main body, and a viewing portion located on the front end side of the attachment portion. The cover member includes a substantially opaque first cylindrical portion, and a substantially transparent second cylindrical portion extending toward the front end from the o...
