Abstract:
1. A flat tire repair kit comprising a compressor device comprising a compressed air discharge port to discharge compressed air, and a bottle unit comprising a bottle container containing a puncture-sealing agent and a cap provided on an opening of the bottle container; wherein: said cap comprises an air intake port capable of connecting to said compressed air discharge port and capable of sending the compressed air from the compressed air discharge port into the bottle container through a first flow channel, a sealing agent/compressed air outlet port to bring out in succession the puncture-sealing agent and the compressed air from said bottle container through a second flow channel by the sending of this compressed air, and said first flow channel provided with a unidirectional valve to prevent from the puncture-sealing agent from flowing back toward the compressor device; said compressor device comprises a cylinder comprising a pump chamber to compress the air with a back-and-forth motion of a piston and a surge chamber to receive the compressed air from the pump chamber via a unidirectional valve; said surge chamber comprises an outlet to send the compressed air from the surge chamber to said compressed air discharge port, a manometer port to connect with a manometer to measure the pressure of the compressed air, and a relief valve connecting port to connect with relief valve to release overpressure; said compressed air discharge port is formed at an opening end of a connecting cylindrical portion integrally connected with the cylinder; said compressed air discharge port and said air intake port are directly connected, without an intervening hose; and said surge chamber volume (Q
