    • The present invention provides a cap assembly, comprising: an outer cap; and an internal structure supported in an internal space, with a gas passageway in communication with external air being defined between the internal structure and the outer cap, the internal structure comprising a two-way vent hole extending to the vicinity of an outer cap base part and a one-way vent hole disposed remotely from the outer cap base part, the two-way vent hole being constructed to allow air in a tube member to be discharged into external air via the two-way vent hole and the gas passageway, thereby defining a gas discharge path, when the tube member is mounted to the cap assembly in a gas-tight fashion, and being constructed to allow external air to enter the tube member via the gas passageway and the two-way vent hole, thereby defining a first gas intake path; and the one-way vent hole being constructed to allow external air to enter the tube member via the gas passageway and the one-way vent hole, thereby defining a second gas intake path, but to prohibit air in the tube member from being discharged into external air via the one-way vent hole. The present invention also provides a reservoir comprising the cap assembly.
