Document Type and Number:
WIPO Patent Application WO/2008/075719
Kind Code:
A1
Abstract:
A sealing device that is simply and reliably operated. When stored, a liquid agent
container (18), in which a sealing agent (32) is placed, is temporarily held above
a pouring unit (20). When the liquid agent container (18) is forcibly pressed
downward in use, the upper end of a pressing jig (82) penetrates through an aluminum
seal (30) into the container, and the sealing agent (32) flows out to a pressurized
liquid supply chamber (40). After that, a compressor unit is activated and compressed
air is supplied into the liquid agent container (18) to place the pressurized
sealing agent (32) into a pneumatic tire (100) via a joint hose (78).
