Patent ID: 8016002

Claim:
A sealing/pump-up device for injecting liquid sealant into a punctured pneumatic tire and then supplying compressed air into the pneumatic tire to raise internal pressure of the pneumatic tire, the device comprising: a liquid agent container containing the sealant and having formed at a lower side thereof a discharge hole for discharging the sealant; a seal member for closing the discharge hole to seal the container; an injection unit coupled to the discharge hole and having inside of the injection unit a liquid supply chamber formed at a side of the seal member that is opposite from an inside of the container; a passage provided at the injection unit so as to face the seal member and connecting an outside of the injection unit and the liquid supply chamber; a compressed air supply passage having one end that opens at a middle portion of the passage; an air supply means coupled to the other end of the compressed air supply passage to supply the compressed air; a gas-liquid supply pipe, one end of which is coupled to the liquid supply chamber and the other end of which can be connected to a valve of the pneumatic tire; a perforating member, at least one part of which is inserted into a liquid supply chamber side of the passage to break through the seal member; and a jig capable of being inserted into the passage from outside of the injection unit and comprising a gas communicating path, one end of which opens at a tip end side and the other end of which opens at a side face at a side that is opposite from the tip end side, the one end of the gas communicating path reaching an upper side in the container and the other end of the gas communicating path communicating with the gas supply path of the injection unit when the jig is inserted into the passage; wherein the jig and perforating member are separated from each other.
