A resin-based adhesive such as terpene-phenol resin, polyvinyl ester, polyvinyl alcohol, and polyvinylpyrrolidine is blended.

When the synthetic isoprene rubber is used as a base, other synthetic rubbers such as acrylic rubber, methacryl rubber, styrene butadiene rubber, acrylonitrile butadiene rubber, ethylene vinyl acetate rubber, chloroprene rubber, vinyl pyridine rubber, butyl rubber, etc. At this time, the synthetic isoprene rubber is preferably blended in the base at least 40% by weight or more. When a natural rubber is used as a base, the natural rubber is preferably blended in an amount of 10 to 80% by weight, more preferably 40 to 60% by weight.

The storage container 4 has, for example, a storage volume 700
In an unused state such as at the time of purchase, it is preferable that the entirety of the storage container 4 be filled with the sealant without air being mixed therein, thereby preventing deterioration of the sealant.

The sealant extracting unit 3 is a pressure-resistant integrally molded product made of a recyclable synthetic resin and lightweight metal, and has a pedestal 3A and the storage container 4 standing upright on the pedestal 3A. The pedestal portion 3A is connected to the inside of the housing 7 by closing the door plate 10 and the back surface 10A of the door plate 10 and the air supply source 2.
The joint 3B faces upward due to the horizontal rotation of the door plate 10.

As shown in detail in FIG. 3, the joint portion 3B includes an outer cylinder portion 35 having an inner thread portion for screwing the neck portion 4B of the storage container 4 and removably connecting the neck portion 4B thereto.
Gas inlet 1 for taking in compressed air from air supply 2
2, a sealant delivery flow path J is formed which communicates with the outlet 13 for taking out the puncture sealant of the storage container 4 through the inside of the storage container 4.

An air pipe 36 extending from the gas inlet 12 and extending through the bottom plate 35A of the outer cylindrical portion 35 at the center of the outer cylindrical portion 35 is formed.
And an L-shaped seal and air passage extending from the outlet 13 and surrounding the air pipe 36 and rising and opening around the air pipe 36 and communicating with the air pipe 39.

The gas inlet 12 and the outlet 1
In the present embodiment, the tube portions 12A and 13A forming the 3 are arranged in a straight line. However, they may be arranged at an angle such as a right angle, and may be arranged in parallel by bending the bottom plate 35A. it can.

The gas inlet 12 and the gas supply source 2
Is connected in advance by a pipe 5 and therefore the gas inlet 1
An outer thread for connecting a joint is threaded on the tube portion 12A forming the second portion. The pipe portion 13A forming the outlet 13 has
A connection section 13C having a sawtooth-shaped longitudinal section is provided via a three-way valve 13B for releasing the residual pressure of the tire. The three-way valve 13B can be omitted.

A tube 6 such as a hose for supplying the puncture sealant to the tire is connected to the connecting portion 13C in advance, and a union nut 40 for connecting to a tire nipple is provided at the tip of the tube 6. Provided. Further, one fitting (not shown) of a so-called one-touch connection joint is attached to the connecting portion 13C of the pipe portion 13A, and the other fitting (provided at the free end of the pipe body 6 that is not connected beforehand). (Not shown).

Accordingly, when the tire is punctured, the door plate 10 for taking out the integrated puncture emergency repair device 1 is opened, and the union nut 40 at the tip of the tube 6 is connected to the nipple of the tire. Further, the tire residual pressure is released by the three-way valve 13B, and the exhaust pressure that is burdened at the beginning of the operation of the gas supply source 2 is reduced or eliminated. Thereafter, the three-way valve 13B is operated to make the pipe portion 13A conductive. When the tube 6 is capable of one-touch connection, the remaining pressure is released from the other end by attaching the tip to the tire, and then the other end of the tube 6 is connected by one-touch connection.

Further, the pressure regulating valve 2C is set to 1 according to the type of the tire.
The pressure is adjusted to about 00 to 1000 MPa. The integrated puncture emergency repair device 1 itself can be classified according to the pressure. Further, the neck 4B of the storage container 4 is connected to the outer cylinder 35 of the joint 3B of the sealant extracting unit 3, and the plug of the power cable 2D is connected to, for example, an outlet of a cigarette lighter of the vehicle, and the switch 2B is connected. Turn on to operate the gas supply source 2.

Since the residual pressure is reduced, it is not necessary to operate the gas supply source 2 against the back pressure from the tire.
In particular, even when a small compressor is used as the gas supply source 2, it is possible to prevent the current at the time of starting from excessively increasing. Before the operation of the gas supply source 2 is started, a check valve can be interposed, for example, in the pipe portion 12A in order to prevent the puncture sealant from flowing backward from the sealant extraction unit 3.

By operating the gas supply source 2,
As shown by the arrow F in FIG. 3, the gas is guided from the gas inlet 12 into the storage container 10 via the air passage J1, passes through the puncture sealant, and is located above the boundary surface K of the puncture sealant. To gather. The gas in this space presses the puncture sealant on the opening side (lower side) due to the increase in pressure, and the sealant can be extruded into the tire via the seal / air path J2 and the tube 6.

At this time, the narrow portion 4C formed on the inner periphery of the neck portion 24 guides the puncture sealant and smoothes its flow. Therefore, the narrow portion 4C is connected to the seal / air pipe 39.
Is formed at a height near the upper end of the.

In order to prevent the puncture sealant remaining in the storage container 4 even after the required amount of the puncture sealant is filled in the tire, it is preferable to store the puncture sealant according to the type of the tire. It is better to set the amount.
The gas that subsequently flows from the gas inlet 12 after the puncture sealant flows out flows directly into the tire T. In this way, the tire is filled to the operating pressure or at least the pressure at which the vehicle can travel a certain distance after taking in the sealant. In this way, the integrated puncture repair device can automatically puncture and inflate.
