This invention discloses a sealant bottle for tire repair of gas pressure type which comprises a bottle body configured for containing sealant. The bottle body is provided with a sealant outlet and an air inlet, wherein a bottle cap is disposed at the sealant outlet and the air inlet is connected with a straight pipe assembly. An air-inlet end of the straight pipe assembly is connected with an air throat for transferring the air into the straight pipe assembly, and the air throat is further provided with an explosion proof element. A sealant guiding pipe disposed within the bottle cap is comprised of a first pipe section arranging along the axial direction of the bottle body and a second pipe section perpendicular to the first pipe section. A second step is disposed between inlets of the first pipe section and the second pipe section, and a rubber plug is further disposed between the inlet of the first pipe section and the second step. In this invention, when the pressure within the bottle body is too large, the explosion proof element on the air throat can be connected to the surrounding atmosphere which thus releases the air within the bottle body through the air releasing hole, lowers down the high pressure within the bottle body and ensures the safety usage for the sealant bottle. This invention is simple in structure and low in cost. Besides, it ensures the safety operation during the process of tire repair. |
