  • Patent number: 5894962
    Abstract: This present invention relates to a soda bottle cap having a shell with a spout and a flexible top, and a seal that has an opening through which liquid can flow out when the flexible top is pressed down. With the structure of this soda bottle cap it is possible to release the carbonated liquid from the soda bottle using the high pressure of CO.sub.2 gas inside. When the flexible top is pressed down, the seal changes shape and does not block inner hole (6) so that the liquid in the bottle can be pushed out through the tube(12), and then through the center hole(9) of the seal, and then through channels (10) of the seal, and then through the inner hole (6) of the shell, and then through the spout (4) by the inner hole (6) of the shell, and then through the spout (40 by the high pressure of CO gas in the bottle. When the force on the flexible top (7) is released after use, the flexible top and the seal go back to its original shape.
