The invention discloses a funnel type rice wine bottle cap capable of relieving leakage. The problem of leakage of a rice wine set is solved. The funnel type rice wine bottle cap comprises a bottle cap body with an inner face thread and a sealing ring, a bottle opening with an outer face thread, a bottleneck with a piece of funnel-shaped rubber, two pieces of cylindrical rubber provided with arc-shaped parts and embedded in the top end in the bottle cap body, and a glass ball. The bottle opening is covered with the bottle cap body. The inner face thread of the bottle cap body is connected with the outer face thread of the bottle opening. The sealing ring of the bottle cap body is tightly attached to the edge of the bottle opening to enhance the sealing effect. The two pieces of cylindrical rubber provided with the arc-shaped parts and embedded in the top end in the bottle cap body are directly inserted in the bottle opening. The piece of funnel-shaped rubber is arranged in the bottleneck. When the bottle opening is covered, a round notch of a funnel is covered with the inside glass ball, the lower ends of the two pieces of cylindrical rubber provided with the arc-shaped parts justly press the glass ball so that the glass ball can be fixed, liquid and gas in a wine bottle can be further prevented from leaking out of the wine set, and the sealing effect is enhanced. When the rice wine bottle is opened, the wine bottle cap body is taken away, the wine bottle is slightly inclined, the glass ball slides to one side, and the wine liquid flows out. The funnel type rice wine bottle cap has the beneficial effects that on the premise that the rice wine set can be normally used, liquid and gas in the wine bottle can be further prevented from leaking out of the wine set, and the sealing effect is enhanced.
