The present invention relates to a cap for a syringe that is joined to a tip of the syringe by a screw and thereby closes and seals a discharge outlet thereof, and comprises: an outer housing (10) which is joined to a lure lock disposed at a connecting member of the syringe by a thread portion (11) at a lower part thereof and includes a connecting member (13) including a shoulder member (13c) that protrudes inwardly between upper and lower joining holes (13a) (13b); and an inner packing (20) which is forcibly inserted into the connecting member (13) to be joined thereto and includes an upper head (21) and a lower body (22) which correspond to the upper and lower joining holes (13a) (13b), respectively, and a recess (23) which corresponds to the shoulder member (13c), wherein the inner packing (20) has a configuration in which to two pieces are joined together, which is simpler than conventional three-piece configurations, and thereby improves production productivity and assembly productivity, and further provides functions for closing and sealing the discharge outlet and for joining by means of a screw. |
