Soy bottle cap

Abstract

The invention discloses a soy bottle cap. The soy bottle cap is characterized in that an upper cap is fixedly locked at the outside of a bottle cap main body; a flow guide ring is fixedly locked on the top of the bottle cap main body; a sealing ring is arranged at the inner side of the bottle cap main body; the sealing ring comprises a columnar outer cylinder and an annular sealing groove; the top of the outer cylinder is connected with the inner side face of the top of the bottle cap main body; the bottom of the outer cylinder is connected with the outer edge of the annular sealing groove; the inner edge of the annular sealing groove is connected with a pull ring; a retainer ring is arranged on the bottom surface of the flow guide ring; the lower end of the retainer ring stretches into the annular sealing groove; the lower end face of the retainer ring is lower than the inner edge of the annular sealing groove; a flow guide opening is formed at a position located at the outer side of the retainer ring on the flow guide ring; and a sealing ring cap matched with the flow guide opening is arranged on the inner top face of the upper cap. In the soy bottle cap disclosed by the invention, the sealing ring is arranged at the inner side of the bottle cap main body, so that the residual soy flows into the annular sealing groove to form liquid seal after the bottle is tilted, and the sealing ring and the retainer ring block the passage by which air enters into the bottle so as to prevent the air from flowing into the bottle to prevent the continuous oxidization of soy.

Description
