Seal bottle assembly

A seal bottle assembly comprising:

• a bottle having a top opening;
• a first room defined in the bottle and communicating with the top opening;
• a cap removably mounted to the top opening of the bottle to seal the first room, the cap including a second room defined therein, a radial hole defined radially through the cap and communicating with the second room, the radial hole including a first opening located at an inner periphery of the cap, and a second opening located at an outer periphery of the cap, a restriction ring extending radially and inward from an inner periphery of the first opening of the radial hole, the restriction ring including multiple protrusion protruding from an inner periphery thereof, multiple recesses defined in the inner periphery of the restriction ring, multiple blocks extending from the inner periphery of the radial hole;
• a switch unit having a seal part and a control part, the control part having two stop plates and a tube extending from an inner side thereof, the stop plates located around the tube, a communication path defined between the tube and the stop plates;
• the stop plates and the tube of the control part inserted into the radial hole from the second opening of the outer periphery of the cap, the control part including at least one notch defined radially in an outer periphery thereof, the at least one notch communicating with the radial hole, the seal part including a tongue that is inserted into the radial hole from the first opening of the inner periphery of the cap, the tongue engaged with the tube;
• when the control part is pushed toward the seal part, the tube pushes the seal part toward the second room so that the first room, the second room, the recesses, the radial hole and the at least one notch are in communication with each other;
• a pressure in the first and second rooms is the same as that of outside of the bottle assembly so that the cap is removable relative to the bottle;
• when the control part is pulled away from the seal part, the seal part is moved to seal a communication between the first and second rooms, the pressure in the first and second rooms is different from that of outside of the bottle assembly so that the cap is not removable relative to the bottle;
• when the control part is rotated within the radial hole, the two stop plates contact the blocks to restrict the control part from being pushed toward the seal part.
