Discharge apparatus

A discharge device comprising:

• a pressurized product including a container filled with a concentrate and a pressurizing agent and sealing the concentrate and the pressurizing agent;
• and
• a discharge member configured to discharge the concentrate, the discharge member breaking through the pressurized product when the discharge member is mounted on the pressurized product,
• wherein the discharge member comprises:
• a valve, and
• a cap which covers the valve and is detachably mounted to the pressurized product, and
• wherein the container comprises:
• a container body, and
• a lid sealing an opening of the container body, and
• wherein the lid comprises:
• a closing part which is broken and pushed through by the discharging member when the discharge member is mounted on the pressurized product, and
• a movable lid which is pushed to an open state by the closing part or the discharge member when the discharge member is mounted on the pressurized product, allowing the concentrate to discharge through the closing part, and which is pushed to closed state by the pressure of the pressurizing agent as the discharge member is removed from the pressurized product, preventing the concentrate from discharging through the closing part,
• wherein the valve has a housing that houses a stem,
• the housing has a seal opening part at the lower end to break through the closing part,
• the lid has a fitting cylinder part into which the housing is inserted,
• the closing part is located at the bottom of the fitting cylinder part,
• a sealing member is attached to the outer circumference of the housing to form a seal between the inner circumference of the fitting cylinder part and the outer circumference of the housing.
