  • Patent number: 8596310
    Abstract: A sealing and pump-up device capable of suppressing sealing agent contained in a sealing agent container body from leaking and preventing damage to a casing body even if an operator mistakenly attempts to remove the sealing agent container body. A connection body 70 is retained to a seal opening device 60 by fitting force between first claws 94A and a leg portion 36 and between second claws 96A and the leg portion 36. An operator might conceivably mistakenly attempt to remove a liquid agent container 18 from the seal opening device 60. However, the fixing force of the screw 128 in the circular hole 122 is determined by such factors as the shape of each member so as to be weaker than the sum of the fitting force (retaining force) between the first claws 94A and the leg portion 36 and the fitting force (retaining force) between the second claws 96A and the leg portion 36.

  • Patent number: 8226377
    Abstract: When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96.

  • Patent number: 8016002
    Abstract: 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).
