Method for recovering puncture repair liquid

摘要

A valve core is removed from a tire valve 3 of a wheel 2 with a tire 1 where puncture repair liquid 4 has been injected. Pressurized air filled in the tire 1 is discharged via the tire valve 3. A tube 10 is inserted through the tire valve 3 to bring the tube 10 to a liquid surface of the puncture repair liquid 4 while the pressurized air in the tire 1 is being discharged. The puncture repair liquid 4 in the tire 1 is recovered via the tube 10 using a residual pressure in the tire 1. In this manner, the puncture repair liquid can efficiently be recovered without cutting off the tire valve.

1. A method for recovering puncture repair liquid, comprising:
preparing a tube to be inserted into a tire through a tire valve mounted to a wheel; removing a valve core from the tire valve of the wheel with the tire where puncture repair liquid has been injected; discharging, through the tire valve, pressurized air filled in the tire; inserting the tube through the tire valve so as to bring the tube to a liquid surface of the puncture repair liquid while discharging the pressurized air in the tire; and recovering the puncture repair liquid in the tire via the inserted tube using a residual pressure in the tire, wherein the method further comprises: grounding the tire of the wheel were the puncture repair liquid has been injected in the tire such that a central shaft of the tire becomes horizontal; and arranging the tire such that the tire valve of the wheel is located at a position shifted by 20 degrees or more, around the central shaft of the tire, from a position directly below the central shaft, wherein the discharging the pressurized air via the tire valve includes discharging the pressurized air in the arranged tire via the tire valve, and the inserting the tube includes: inserting the tube through the tire valve into the tire while the pressurized air in the tire is being discharged; and bringing the tube to the liquid surface of the puncture repair liquid by rolling the tire after the insertion such that the tire valve is at the position directly below the central shaft of the tire.
