Provided is an exposure-preventing cap of a novel and simple structure that, by being mounted on a vial, can more reliably inhibit leaking of drug solution to an outside when pulling out and collecting drug solution in a syringe from the vial. An exposure-preventing cap, which is mounted on a mouth of a vial sealed with a rubber stopper, wherein a puncturing hole is formed in a center part of a cap-shaped housing that is attached to a mouth of the vial, and a rubber membrane is arranged at the puncturing hole so as to form an internal space between facing surfaces of the rubber membrane and the rubber stopper. The rubber membrane has a dome shape that is convex facing the rubber stopper.

Exposure-preventing cap

A plug for a container capable of improving air-tightness and liquid-tightness is provided. A plug includes a first split piece having a cylindrical first fitting portion to be mounted on an opening portion of a container body and fitted to an opening portion space of the opening portion, an end wall which blocks one end of the first fitting portion, and a first flange portion extending outwardly in a radial direction of the first fitting portion from the other end thereof; and a second split piece having a second fitting portion which is fitted to the first fitting portion of the first split piece and forms a closed space between the end wall and the second fitting portion and a second flange portion extending outwardly in a radial direction of the second fitting portion therefrom.
