Puncture repair liquid injection method and injection device

1. A puncture repair liquid injection method comprising the steps of:

using a puncture repair liquid injection device comprising a container having a liquid containing portion containing a puncture repair liquid, an outlet for discharging the puncture repair liquid, and an inlet for introducing compressed air; an injection hose connected between a tire valve of a wheel mounted on a tire and the outlet of the container; and a compressor having a pressure adjuster for selecting an air pressure reduced relative to an air pressure at a time of normal driving which is for filling the tire air pressure; the method further comprising the steps of connecting the injection hose between the tire valve and the outlet of the container, connecting the compressor to the inlet of the container, selecting a reduced air pressure as a pressurizing force by the compressor by an operation of the pressure adjuster, injecting the puncture repair liquid into the tire by pressurizing an interior of the container based on the reduced air pressure, selecting the liquid containing portion of the container to be configured from a plastic material, and selecting a thickness of the liquid containing portion to be 2.0 mm or less;

the pressure adjuster including a pressure adjusting valve, a pressure adjusting button driving the pressure adjusting valve, and a lock mechanism; the lock mechanism locking the pressure adjusting button in a push-in position;

wherein the pressure adjusting button comprises a plate-shaped pinch portion on a top surface side to enable twisting of the pressure adjusting button.

2. The puncture repair liquid injection method according to claim 1 , further comprising:

selecting the reduced air pressure to be 100 kPa or less; and

reducing the air pressure at a time of normal driving from between 200 kPa and 400 kPa to the reduced pressure.

3. The puncture repair liquid injection method according to claim 2 , further comprising selecting the reduced air pressure to be between 30 kPa and 60 kPa.

4. A puncture repair liquid injection device comprising: a container having a liquid containing portion containing a puncture repair liquid, and having an outlet for discharging the puncture repair liquid and an inlet for introducing compressed air; an injection hose connected between a tire valve of a wheel mounted on a tire and the outlet of the container; and a compressor having a pressure adjuster for selecting an air pressure reduced relative to an air pressure at a time of normal driving for filling tire air pressure;

the pressure adjuster including a pressure adjusting valve, a pressure adjusting button driving the pressure adjusting valve, and a lock mechanism; the lock mechanism locking the pressure adjusting button in a push-in position; wherein the liquid containing portion of the container is configured from a plastic material, and a thickness of the liquid containing portion is 2.0 mm or less; and

the pressure adjusting button comprises a plate-shaped pinch portion on a top surface side to enable twisting of the pressure adjusting button.

5. The puncture repair liquid injection device according to claim 4 , wherein the pressure adjuster includes settings for setting the pressure adjusting valve to a normal driving air pressure between 200 kPa and 400 kPa and to a reduced air pressure of 100 kPa or less.

6. The puncture repair liquid injection device according to claim 5 , wherein the pressure adjuster includes the settings for setting the pressure adjusting valve to a reduced air pressure between 30 kPa and 60 kPa.
