It comprises a base member (7) mountable on an eyedropper (A) capable of storing liquid, an overcap (8) attachable to the base member (7), a push-in member (9) inserted and held in the base member (7) for slide movement relative to the base member (7), having a groove (91) laterally disposed for guiding the liquid to the outside, and capable of being pushed in toward the eyedropper (A) by the overcap (8) to cancel the sealed state of the eyedropper (A), a first close contact member (11) closely contacting the push-in member (9) from outside and installed at the front end portion (77) of the base member (7) to allow outflow of the liquid, and a second close contact member (12) disposed on the inner periphery of the base member (7), capable of closely contacting the pushed-in push-in member (9), preventing outflow of the liquid, and allowing inflow of the outside air. |
