Claims

[Scope of utility model registration request]

A diaphragm cap that can be attached to a bottle mouth and that forms a content delivery passage and a content return passage whose upper and lower ends in the direction of the central axis merge and branch in the middle, and which can be attached to the bottle mouth. A base plug board that can be attached, a middle plug board that is located above the base plug board in the axial direction, and a diaphragm board that is located above the middle plug board in the axial direction, and the base plug board has a central part that has an axially a valve seat surface consisting of a cylindrical surface formed in a cylindrical shape, and a first content flow port forming a part of a lower end merging portion of the content delivery passage and the content return passage on the outside of the valve seat face; The middle plug disc is displaceably engaged with the base plug disc in the axial direction and is protruded downward in the axial direction, and the displacement causes the first contents flow port to open. A first tube having a plug part that opens and closes and protrudes axially downward inside the plug part and has a cylindrical shape and engages with the valve seat surface of the base plug body to interrupt the content return passage. It has a valve cylinder constituting a check valve, and has a valve seat surface that protrudes upward in the axial direction inside the valve cylinder and has a tapered surface on its outer surface, and has a valve seat surface formed of a tapered surface on the outer surface, and has a valve seat surface formed in the center part that is connected to the base plug body by the displacement. It has a valve seat cylinder that opens and closes in abutment and separation to form a second content distribution port that forms a part of the content return passage, and also forms a part of the content delivery passage on the outside of the valve seat surface. A third content distribution port is formed, and the diaphragm disc has a second check valve whose inner surface abuts and separates from the valve seat surface of the inner stopper disc to disconnect the content delivery passage. an annular valve part that forms a valve surface and a nozzle port that forms the confluence of the upper ends of the content delivery passage and the content return passage; A diaphragm cap comprising a diaphragm provided and energized in a direction to close the second check valve.
