The upper end side of the cylindrical portion 42A constitutes the insertion convex portion 6 that is inserted into the mouth portion 2A. A circumferential groove 8 fitted with a seal ring 7 is recessed in the outer peripheral surface of the insertion convex portion 6. At the lower end position P of the insertion convex portion 6, a flange-like positioning portion 6E that comes into contact with the lower end of the mouth portion 2A protrudes. Although not shown, the height H1 from the lower end position P of the circumferential groove 8 is preferably 50% or more, more preferably 60% or more of the height H0 of the insertion convex portion 6 as in the first embodiment.

  The retaining means 10 of the present example is provided on a projecting portion 36 projecting radially outward from the outer peripheral surface of the insertion convex portion 6 and a peripheral wall portion of the mouth portion 2A, and engages the projecting portion 36 in the ejecting direction. A stop hole portion 37.

  As conceptually shown in FIG. 6, the protruding portion 36 is formed between the positioning portion 6 </ b> E and the seal ring 7. The protruding portion 36 includes a bottom surface 36a that protrudes substantially perpendicularly from the outer peripheral surface of the insertion convex portion 6, and an inclined surface 36b that inclines and extends in a direction in which the protruding height decreases upward from the distal end portion of the bottom surface 36a. It consists of a triangular prism shaped block.

  The locking hole portion 37 is a rectangular through-hole into which the protruding portion 36 can be inserted, and the lower surface 37a of the locking hole portion 37 abuts on the bottom surface 36a of the inserted protruding portion 36, whereby the protruding portion The portion 36 can be locked in the pulling direction.

  As shown in FIG. 5, the air supply pipe portion 43 of the cap body 40 rises concentrically with the cylindrical portion 42 </ b> A from the bottom portion 42 </ b> B, and the central hole forms the first flow path 20. In this example, the case where the one-way valve 44 for preventing the back flow of the puncture repair liquid L from the bottle container 2 is arranged in the first flow path 20 is shown. On the other hand, a known structure can be adopted as the valve 44.

  Similarly to the first embodiment, the bottom portion 42B is provided with a compressor connecting portion 22 and a first detachment preventing portion 31A that constitutes a preventing means 31.

  The sheath tube 41 is externally held by the air supply tube portion 43 so as to be slidable in the vertical direction. The sheath tube 41 is connected to the compressor 5 by the prevention means 31 and is connected to the sheath tube 41. A push-up lever 45 that pushes upward is formed. The push-up lever 45 includes, for example, two or three projecting pieces extending from the lower end of the sheath tube 41 through the bottom portion 42B and projecting downward. The push-up lever 45 pushes up the sheath tube 41 upward by coming into contact with, for example, the upper surface of the compressor 5.

  The sheath tube 41 is provided with second closing means 46 for closing the second flow path 21 so as to be movable together with the sheath tube 41. A first closing means 47 that closes the first flow path 20 is disposed at the upper end of the air supply pipe 43. These first and second closing means 47 and 46 are operated by pushing up the sheath tube 41 and open the first and second flow paths 20 and 21.

  The second flow channel 21 includes an annular vertical flow channel portion 21A formed by a gap between the outer peripheral surface of the sheath tube 41 and the inner peripheral surface of the cylindrical portion 42A, and the vertical flow channel portion 21A. A horizontal flow path portion 21B that bends and extends to the tip of the tire connection portion 24 is provided.

  The inner peripheral surface of the cylindrical portion 42A includes a large diameter surface portion, a small diameter surface portion, and a step portion therebetween.

  The second closing means 46 of this example is formed by seal rings 46U and 46L such as O-rings provided so as to be able to move integrally with the sheath tube 41. In the state before connection (shown in FIG. 5), the upper seal ring 46U comes into contact with the small diameter surface portion and closes the second flow path 21. In the connected state (not shown), the upper seal ring 46U moves upward beyond the stepped portion by pushing up the sheath tube 41. As a result, a gap is formed between the upper seal ring 46U and the large diameter surface portion, and the second flow path 21 is opened.

  The first closing means 47 is an inner lid that is fitted to the upper end portion of the air feeding pipe portion 43, and this inner lid is pushed up by the sheath tube 41 and is detached from the upper end portion of the air feeding pipe portion 43. The first flow path 20 is opened.

  Next, FIG. 8A shows an embodiment of the bottle unit 1 of the second invention.

  In this example, the cap 4 has an extrapolated cylinder portion 50 that is extrapolated from below to the mouth portion 2A. A circumferential groove 8 fitted with a seal ring 7 is recessed in the outer peripheral surface of the mouth portion 2A.

As shown in FIG. 8 (B), the protruding portion 51 is inclined in such a direction that the protruding height decreases downward from the upper surface 51a protruding substantially perpendicularly from the outer peripheral surface of the mouth portion 2A and from the tip of the upper surface 51a. It consists of a triangular prism block having an inclined surface 51b.

  The locking hole portion 52 is a rectangular through-hole into which the protruding portion 51 can be inserted. The upper surface 52a of the locking hole portion 52 abuts on the upper surface 51a of the inserted protruding portion 51, whereby the protrusion The part 51 can be locked in the pulling direction.

  The other structure of the cap body 40, the structure of the sheath tube 41, the structure of the prevention means 31, and the like are the same as those in the second embodiment, and the description thereof is omitted.

  In FIG. 5 and FIG. 8 (A), the code | symbol 39 is a hose clamp which fixes the hose 25 for tire connection, and is integrally molded by the bottle container 2. In FIG. The integral molding of the hose clamp 39 into the bottle container 2 can be achieved by eliminating the conventional screw portion (shown in FIG. 9) provided at the mouth of the bottle.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
