Claims

[Scope of Claim for Utility Model Registration] A bellows-incorporated bottle that inhales or discharges liquid into the bellows bottle by expanding and contracting a bellows bottle inside the bottle body using compressed air, the inner peripheral surface of the bottle body. and an outer peripheral surface of the bottom of the bellows bottle in a vertically slidable manner, communicating with a first airtight chamber formed above the bottom of the bellows bottle, and forming an air supply port at the top of the bottle body. , forming an air inlet/outlet in communication with a second airtight chamber formed below the bottom of the bellows bottle, and alternately supplying compressed air to the air supply inlet and the air inlet/outlet; Connecting an air supply means, communicating with the inside of the bellows bottle to form a liquid inlet/outlet at the mouth of the upper part of the bellows bottle, and forming a liquid inlet/outlet at the mouth of the bellows bottle below the mouth of the bellows bottle opposite to the inner peripheral surface of the bottle body. A recess is formed in the outer circumferential surface, an elastic sealing member is removably fitted into the recess, and a built-in bellows is provided in which the space formed by the sealing member and the recess communicates with the first airtight chamber through an air supply passage. shaped bottle.
