  When repairing a punctured tire with the sealing / pump-up device 10 configured as described above, an operator takes out the air hose 23 and connects the adapter 28 of the air hose 23 to the tire valve of the tire. Next, the operator rolls over the casing 14 to cause the sealing agent 12 in the liquid agent container 18 to flow into the liquid supply hose 30. When the operator moves a power switch (not shown) from the “off position” to the “on position”, the liquid supply pump 20 operates to suck the sealing agent 12 from the liquid container 18 and pressurize the sealing agent 12. Discharge. At this time, the connection destination of the three-way valve 26 is set on the air hose 23 side. The discharged sealing agent 12 passes through the three-way valve 26, is sent to the air hose 23, and is supplied into the tire through the tire valve.

  The sealing / pump-up device 10 automatically stops the feed pump 20 when the specified amount of the sealing agent has been injected into the tire, and simultaneously connects the air hose 23 to the compressor 16 via the three-way valve 26. After switching to the side, the air compressor 16 is operated. Thereby, the air compressor 16 discharges compressed air, and this compressed air is supplied into the tire through the air hose 23 and the tire valve to inflate the tire. Thereafter, when the operator confirms that the internal pressure of the tire has reached the specified pressure by the pressure gauge, the operator returns the power switch to the “off position” and stops the air compressor 16.

  Next, the operator pulls out the adapter 28 from the tire valve and removes the air hose 23 from the tire. In this state, the worker temporarily travels for a certain distance using the tire into which the sealing agent 12 has been injected. As a result, the sealing agent 12 is uniformly diffused inside the tire, and the sealing agent 12 is filled in the puncture hole to close the puncture hole. The operator checks the internal pressure of the tire with a portable pressure gauge or the like. At this time, when the internal pressure of the tire is lower than the specified pressure, the worker raises the tire to the specified pressure again by the sealing / pump-up device 10.

  When the sealing / pump-up device 10 is used next time, the empty liquid container 18 is replaced with a new liquid container 18 containing the sealing agent 12. In the exchange, the engagement between the lid-side first engagement portion 52 and the housing-side first engagement portion 60 is released, the lid member 50 is moved and removed from the housing 14, and the opening 34 is opened. Next, the perforated part 32 is removed from the empty liquid container 18 and taken out from the container storage part 40 in the housing 14. Then, a new liquid agent container 18 is placed in the container storage unit 40, the perforated part 32 is attached to the neck 18A of the liquid agent container 18, the sealing plug 19 is perforated, and the liquid agent container 18 is set in the sealing / pump-up device 10. .

  According to the present embodiment, the opening 34 is configured at a position corresponding to the container housing portion 40 in which the liquid medicine container 18 is accommodated, and the opening 34 can be opened by removing the lid member 50. The liquid container 18 can be exchanged.

  In the above embodiment, the lid member 50 has a shape cut out in an L shape at the end surface of the housing 14. However, as shown in FIG. 5, the lid member 50 has a shape cut out linearly at the end surface of the housing 14. The lid member 55 may be used. Moreover, as shown in FIG. 6, it is good also as the cover member 56 of the shape notched leaving a part of the height direction of the housing | casing 14. As shown in FIG.

  Furthermore, as shown in FIG. 7, one end side in the height direction of the lid member 57 may be attached to the housing 14 by two hinges 57A, and the lid member 57 may be rotatable around the hinge 57A. In this case, the lid-side first engagement portion 58 provided on the other end side in the height direction of the lid member 57 is engaged with the housing-side first engagement portion 64 provided on the housing 14. Thus, the opening 34 can be covered and the opening 34 can be closed.
