Description

  The present invention includes a compressor and a bottle unit in which an extraction cap is attached to a mouth portion of a bottle container containing puncture repair liquid. It relates to a tire flat repair kit.

  For example, in Patent Document 1 below, as shown in FIG. 9, puncture repair liquid and compressed air are sequentially injected into a punctured tire t by compressed air from a compressor d attached to the mouth part a1 of the bottle container a. A puncture repair cap unit b for repairing punctures is described.

  The cap unit b includes a first flow path e for sending compressed air from the compressor d into the bottle container a, and a second flow for sequentially taking out puncture repair liquid and compressed air from the bottle container a by feeding the compressed air. A cap body g having a flow path f and a single inner lid h that simultaneously closes the first and second flow paths e and f.

  Specifically, the cap body g includes a boss portion g2 that rises from the bottom surface of the mounting concave portion g1 into which the mouth portion a1 of the bottle container a is screwed. The upper surface of the boss portion g2 has the first and second boss portions g2. The upper openings e1 and f1 of the flow paths e and f are opened. The inner lid h integrally includes an inner lid main body ha fitted on the outer peripheral surface of the boss portion g2 and a plug shaft hb fitted on the upper opening f1.

  And before use, the bottle unit c is stored in the vehicle with the first and second flow paths e and f closed by the inner lid h. When repairing the puncture, piping is applied to the extraction cap b in this state, and the compressor d is operated. As a result, the compressed air flows into the inner lid body ha through the first flow passage e, and the inner lid h is automatically removed and the first and second flow passages e and f are released by the increase in internal pressure. To make it happen.

  Therefore, it is necessary that the inner lid h does not come off at the time of storage and is easily removed by compressed air at the time of puncture repair. For this purpose, it is required to improve the accuracy of the fitting size between the inner lid h and the cap body g and to manage the fitting force between the inner lid h and the cap body g with high accuracy.

  However, in the conventional structure, fitting variation occurs in both the inner lid main body ha and the plug shaft portion hb. For this reason, higher precision is required depending on the fitting size, resulting in a decrease in yield rate and an increase in process cost in the product inspection process.

  In addition, in the conventional structure, it is necessary that the fitting of the inner lid body ha and the fitting of the plug shaft portion hb be simultaneously released. For example, when the plug shaft portion hb is first removed and a gap is generated, Since the compressed air in the main body ha flows out from the gap into the second flow path f, the internal pressure of the inner lid main body ha does not increase. On the contrary, when the inner lid body ha comes off first and a gap is formed, compressed air leaks into the bottle container a from the gap and the pressure in the bottle container a rises. The pressure difference between inside and outside decreases. As a result, in any case, the inner lid h does not come off from the boss part g2. Thus, it is necessary for the inner lid body ha and the plug shaft portion hb to be detached at the same time, which is also a factor that requires high accuracy.

On the other hand, the compressor side connecting portion 7A includes a claw engaging hole 31 that engages with the hook portion 30B and is prevented from coming off, whereby the compressor 3 and the bottle unit 6 are firmly connected with one touch. . The claw engagement hole 31 of this example is formed in a frame frame 32 that is formed integrally with the nozzle receiver 26.

  However, the puncture repair kit 1 of the present embodiment has the connecting means 7 and the unstable bottle unit 6 can be integrally connected and fixed to the compressor 3 to prevent the bottle unit 6 from falling over during the puncture repair work. it can.

  Further, in the extraction cap 5, the air supply pipe 15 for forming the first flow path 8 is held so as to be slidable up and down with the connection by the connecting means 7. In addition, the opening at the upper end of the air supply pipe 15 is closed by the first closing means 12 including the sealing seal body 34, and the opening projection 35 that can break the sealing seal body 34 into the bottom surface 4 </ b> Bs of the bottle container 4. Is provided. That is, since the first flow path 8 can be reliably closed using the sealing seal body 34, the puncture repair liquid T can be prevented from leaking or flowing out during storage. Further, the sealing seal body 34 can reliably open the first flow path 8 because the unsealing projection 35 is broken through and broken. Moreover, since the breakthrough is automatically performed by lifting the air supply pipe 15 associated with the connection, it is possible to eliminate the occurrence of work mistakes. In this way, while ensuring the opening and closing of the first flow path 8, there is no need for the fitting between the inner lid and the cap body as in the prior art. Disappears. Therefore, the yield rate when forming the extraction cap 5 can be increased, and the process cost in the product inspection process can be reduced.

  In this example, since the second closing means 13 is also provided in the air supply pipe 15, the first flow path 8 and the second flow path 10 can be connected without using the force of compressed air. It can be opened simultaneously and reliably.

  In this example, since the compressed air discharge port 2 of the compressor 3 and the intake port 9 of the extraction cap 5 are directly connected, the hose on the air supply side can be eliminated, and piping work at the puncture repair site is facilitated. In addition, erroneous piping can be prevented.

  Here, as shown in FIG. 1, the upper end of the air supply pipe 15 is preferably positioned above the liquid level Ts of the puncture repair liquid T in the mounted state Y1. The reason for this is that if the compressor 3 is operated in a state where the second flow path 10 side is blocked, the pressure in the bottle container 4 increases abnormally, and the compressor 3 has pulsation, There is a risk that the puncture repair liquid T in the bottle container 4 will flow backward to the compressor 3 side. Therefore, the trouble can be prevented by positioning the upper end of the air supply pipe 15 above the liquid level Ts. The state in which the second flow path 10 side is blocked includes a case where the hose 40 connected to the take-out port 11 is broken and closed, or a case where the tip of the hose 40 is blocked with a cap. obtain.

The projecting portion 43 is divided into a plurality of projecting pieces 45 having spring elasticity, in this example, six projecting pieces 45 by vertically extending slits 44. Of these, at least two, in this example, three projecting pieces 45 are formed as first projecting pieces 45A having a substantially right triangular hook portion 46 projecting outward at the lower end thereof, and the remaining portion is the hook portion 46. It is formed as a second protruding piece 45 </ b> B having no gap.

  On the other hand, the compressor side connecting portion 7A is formed as an annular connecting groove 47 into which the cylindrical projecting portion 43 is fitted, and a groove bottom 47A of the connecting groove 47 is engaged with the hook portion 46. A claw engagement hole 48 that is prevented from coming off is formed. Here, the outer surfaces of the first and second projecting pieces 45A and 45B can be pressed against the inner surface of the connecting groove 47 by the spring elasticity, and the lower end of the second projecting piece 45B is connected to the connecting groove 47. The groove bottom 47A is held. Further, the hook portion 46 of the first projecting piece 45A is engaged with the claw engaging hole 48 of the connecting groove 47 and is prevented from coming off. Thereby, the compressor 3 and the bottle unit 6 are connected firmly and one-touch.
