PROBLEM TO BE SOLVED: To provide a cap which allows a gaseous matter or a liquid to be easily infused as a supplement into a container from the outside by using a simple constitution, in a state that a mouth part is closed and in a sealed state, and a hydrogen-containing beverage production system including the cap.SOLUTION: A cap comprises: a cap body 21; and an introduction part 30 which is disposed integrally with the cap body 21, and through which hydrogen gas can be infused into a container 10 from the outside in a state that a mouth part 11 of the container 10 is closed with the cap body 21 and in a sealed state. The introduction part 30 is connected to an infusion nozzle 40 extending from a hydrogen gas supply source 50, and is, on one hand, in a communicating state for receiving the hydrogen gas accompanying the connection, and is, on the other hand, in a closed state for preventing leakage of contents in the container 10 to the outside upon release of the connection.SELECTED DRAWING: Figure 1 |
