キヤツプ。[Scope of Claim for Utility Model Registration] 1. A cap body with a gap formed around the outer periphery of a valve seat body having an air intake port located approximately in the center of the mouth opening of the squeeze bottle, and an air intake port that is in close contact with the upper part of the valve seat body. A discharge valve that has a valve body supported by a flexible thin plate that covers the mouth opening, and has a valve body that is supported by a flexible thin plate that covers the mouth opening, and as the internal pressure increases, the valve body separates from the valve seat body and opens to pour out the contents. and a vent valve having a valve body that is in close contact with the lower part of the valve seat body to close the intake port and introduce outside air away from the valve seat body as the internal pressure becomes negative. An automatic opening/closing cap characterized in that the portion where the valve body portion comes into close contact with the valve seat body is formed into a thin and flexible portion. 2. A cap body with a gap formed around the outer periphery of the valve seat body, which is equipped with an intake port located approximately in the center of the mouth opening of the squeeze bottle, and a cap body with a gap formed around the outer periphery of the valve seat body, and a cap body with a discharge port that is in close contact with the upper part of the valve seat body and communicates with the intake port. A discharge valve has a valve body supported by a flexible thin plate that covers the opening of the valve body, and when the internal pressure increases, the valve body separates from the valve seat body and opens to discharge the contents. In an automatic opening/closing cap equipped with a vent valve having a valve body that closes the intake port and introduces outside air by separating from the valve seat body as the internal pressure becomes negative, the valve body of the vent valve is attached to the valve seat body. An automatic opening/closing cap characterized by having thin annular protrusions formed in the areas that are in close contact with each other.
