Patent number: 8201586Abstract: To prevent a burr, produced from the joint portion by welding between a liquid agent container and an injection unit, from interfering with a boring member inserted into a jig communication passage when the boring member is inserted into the jig communication passage to prevent the obstruction of the piercing action through a sealing member by the edge of the boring member.Type: GrantFiled: June 13, 2007Date of Patent: June 19, 2012Assignee: Bridgestone CorporationInventors: Masaki Yoshida, Ryuji Izumoto, Shinichi Iwasaki, Rieko Iwasaki, legal representative

Patent number: 8016002Abstract: A sealing/pump-up device for tire that not only ensures the storability of sealing agent but also realizes rapid supply of sealing agent into a pneumatic tire. By insertion of insert part (60A) of jig (60) in jig insertion aperture (42) of sealing device (10), aluminum seal (30) is burst through by means of boring member (50) to thereby drive the same in the container. As the distal end of the insert part (60A) locates in the vicinity of upper wall surface within liquid agent container (18), a compressor unit is operated to thereby supply compressed air into the liquid agent container (18). As the end portion of first passage (62) provided in the jig (60) lies in a position superior to the liquid surface of sealing agent (32), the compressed air realizes rapid supply of the sealing agent (32) into a pneumatic tire without surfacing in the form of bubbles through the sealing agent (32).Type: GrantFiled: November 28, 2006Date of Patent: September 13, 2011Assignee: Bridgestone CorporationInventors: Masaki Yoshida, Yuji Takeda, Shinichi Iwasaki, Rieko Iwasaki, legal representative

Patent number: 7981940Abstract: Provided is a method of treating a sealing compound, in order to recover from the inside of a pneumatic tire the sealing compound that was used for repairing a puncture, the sealing compound including an aqueous solution having at least rubber latex dispersed therein, the method comprising: solid-liquid separating, by injecting a treating agent into the inside of a pneumatic tire into which the sealing compound was injected, the treating agent comprising at least one of a salt that is a reaction compound of an acid and a base and/or a water-soluble organic solvent, mixing the treating agent with the sealing compound inside the pneumatic tire, and aggregating and solidifying the rubber latex in the sealing compound.Type: GrantFiled: May 26, 2005Date of Patent: July 19, 2011Assignee: Bridgestone CorporationInventors: Shinichi Iwasaki, Rieko Iwasaki, legal representative, Ryuji Izumoto, Daisuke Sugio

Patent number: 7891385Abstract: To reliably supply a predetermined amount of sealing agent into a pneumatic tire even if the device is inclined and after the predetermined amount of sealing agent is supplied, to automatically start feeding compressed air into the pneumatic tire. In pumping device 30, when compressed air is supplied to air chamber 54, internal pressure of air chamber 54 increases, and as the internal pressure of air chamber 54 rises, a contained volume of air chamber 54 increases while a contained volume of liquid container 52 decreases. Thus, sealing agent 100 in an amount corresponding to the amount corresponding to the reduction in the contained volume of liquid container 52, is forcibly discharged from discharge outlet 64 and the discharged sealing agent 100 is injected into tire 90.Type: GrantFiled: May 26, 2005Date of Patent: February 22, 2011Assignee: Bridgestone CorporationInventors: Hideshi Yanagi, Daisuke Sugio, Kazuma Nakazawa, Shinichi Iwasaki, Rieko Iwasaki, legal representative, Yuji Takeda, Masaki Yoshida
