Keg cap and keg including keg cap

A keg cap coupled to a coupler of a flow path module for preparing a fermented beverage through an undiluted solution and included in a keg accommodating the undiluted solution, the keg cap comprising:

• a cap body connected to the keg;
• and
• a cap moving member movable up and down inside the cap body, opening and closing a gas discharge flow path through which gas inside the keg moves, and providing an undiluted solution discharge flow path in which an undiluted solution moves,
• wherein, when the coupler is coupled to the keg cap, the gas discharge flow path communicates with a gas flow path of the flow path module, and the undiluted solution discharge flow path communicates with an undiluted solution flow path of the flow path module.

A keg cap coupled to a coupler of a flow path module for preparing a fermented beverage through an undiluted solution and included in a keg accommodating the undiluted solution, the keg cap comprising:

• a cap body connected to the keg;
• a cap moving member formed in a cylindrical shape having a hollow constituting an undiluted solution discharge flow path and moving downward by being pressurized when the cap body is coupled to the coupler;
• and
• a first sealing member provided on an upper part of the cap moving member and moving downward together with the cap moving member to open a gas discharge flow path formed between an inner side of the cap body and an outer side of the cap moving member,
• wherein, when coupled to the coupler, an upper end part of the cap moving member is pressurized by the sealing member of the coupler to block communication between the undiluted solution discharge flow path and the gas discharge flow path through the upper end part of the cap moving member.
