Abstract

A mixing device for mixing a puncture repair liquid and compressed air includes a mixing chamber, a first inlet for supplying the compressed air to the mixing chamber, a second inlet for supplying the puncture repair liquid to the mixing chamber, and an outlet for discharging a mixture of the puncture repair liquid and the compressed air from the mixing chamber. The mixing chamber includes a deposition section for depositing agglomerates contained in the puncture repair liquid. The deposition section is provided between the second inlet and the outlet.

First claim

The invention claimed is:

1. A mixing device for mixing a puncture repair liquid and compressed air comprising:
a mixing chamber;
a first inlet for supplying the compressed air to the mixing chamber;
a second inlet for supplying the puncture repair liquid to the mixing chamber; and
an outlet for discharging a mixture of the puncture repair liquid and the compressed air from the mixing chamber, wherein, the mixing chamber includes a deposition section for depositing agglomerates contained in the puncture repair liquid, and
the deposition section is provided between the second inlet and the outlet.

2. The mixing device according to claim 1 , wherein the deposition section is formed in the vicinity of the outlet.

3. The mixing device according to claim 1 , wherein
the mixing chamber has a surface with which the outlet communicates, and
the deposition section protrudes from the surface of the mixing chamber toward inside of the mixing chamber.

4. The mixing device according to claim 3 , wherein a height of the deposition section from the surface in a protruding direction of the deposition section is from 0.50 to 0.85 times a height of the mixing chamber in the protruding direction.

5. The mixing device according to claim 3 , wherein
the deposition section has a longitudinal cross-sectional shape in a cross section thereof taken perpendicular to a protruding direction of the deposition section, and
a length of the deposition section in a longitudinal direction of the cross-section thereof is from 1.6 to 3.0 times a maximum opening width of the outlet.

6. The mixing device according to claim 5 , wherein the deposition section is formed as a plate.

7. The mixing device according to claim 6 , wherein the deposition section has a thickness of 1.0 mm or more and 2.0 mm or less.

8. The mixing device according to claim 6 , wherein the deposition section has an arc-shaped cross section.

9. The mixing device according to claim 3 , wherein
the mixing chamber has a wall portion opposing the surface, wherein
the first inlet is provided in the surface,
the second inlet is provided in the wall portion, and

the second inlet and the outlet are positioned on both sides of the first inlet with the first inlet therebetween in a plan view.

10. The mixing device according to claim 9 , wherein
a first flow direction of the compressed air flowing through the first inlet into the mixing chamber and a second flow direction of the mixture discharged through the outlet are parallel and opposite to each other.

11. The mixing device according to claim 3 , wherein
the mixing chamber has a wall portion opposing the surface, wherein
the first inlet is provided in the surface,
the second inlet is provided in the wall portion, and
the first inlet and the outlet are positioned on both sides of the second inlet with the second inlet therebetween.

12. The mixing device according to claim 11 , wherein
a first flow direction of the compressed air flowing through the first inlet into the mixing chamber and a second flow direction of the mixture discharged through the outlet are parallel to each other and have the same orientation.

13. The mixing device according to claim 1 , wherein the mixture is an aerosol of the puncture repair liquid and the compressed air.

14. A bottle unit comprising the mixing device according to claim 1 and a bottle container, wherein
the bottle container contains the puncture repair liquid and has a mouth portion for receiving the puncture repair liquid, and
the mixing device is attached to the mouth portion.

15. The bottle unit according to claim 14 , wherein
the mouth portion has a film for keeping the puncture repair liquid airtight,
the mixing chamber has a surface with which the outlet communicates, and
the deposition section protrudes from the surface toward inside of the mixing chamber so as to break the film when the mixing device is attached to the mouth portion.

16. The bottle unit according to claim 15 , wherein the deposition section is formed by a plurality of plates.

17. A puncture repair kit comprising the bottle unit according to claim 14 and a compressor for supplying the compressed air.

18. The bottle unit according to claim 14 , wherein
the mixing device includes a wall portion provided with the second inlet, and
the wall portion is arranged in the mouth portion.

19. The mixing device according to claim 1 , wherein the first inlet has an opening area of from 1.5 to 15.5 times an opening area of the second inlet.

20. The mixing device according to claim 1 , wherein the second inlet is formed by a plurality of holes.
