Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the puncture repair kit of Patent Document 1, since compressed air is injected after injecting the puncture repair liquid, a large amount of puncture repair liquid needs to be injected to block the punctured part with the puncture repair liquid, and the time required for the operation is also long.

[0005] The present disclosure has been devised in view of the above actual situation, and the main object is to provide a mixing device, a bottle unit, and a puncture repair kit for performing puncture repair in a short time.

Means for Solving the Problems

[0006] This disclosure relates to a mixing device for mixing tire repair fluid 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 tire repair fluid to the mixing chamber, and an outlet for discharging a mixture of the tire repair fluid and compressed air from the mixing chamber, wherein the mixing chamber includes a deposit section for depositing aggregates contained in the tire repair fluid, and the deposit section is formed between the second inlet and the outlet. [Effects of the Invention]

[0007] The mixing apparatus of this disclosure, having the above-described configuration, can perform tire puncture repair in a short amount of time. [Brief explanation of the drawing]

[0008] [Figure 1] This is a cross-sectional view conceptually illustrating one embodiment of the tire repair kit of the present disclosure. [Figure 2] This is a schematic diagram of the mixing apparatus of this embodiment. [Figure 3] This is a cross-sectional view of line AA in Figure 1. [Figure 4] This is a schematic diagram of the mixing apparatus according to the second embodiment. [Figure 5] This is a cross-sectional view conceptually illustrating a tire repair kit according to a third embodiment. [Modes for carrying out the invention]

[0009] One form of implementation of this disclosure will be described in detail below with reference to the drawings. Figure 1 is a conceptual cross-sectional view of the tire repair kit 1 of this embodiment. As shown in Figure 1, the tire repair kit 1 is suitably used to supply a tire repair fluid and compressed air to a punctured tire T. The tire repair kit 1 of this embodiment includes a bottle unit 2 and a compressor 3 for supplying compressed air.

[0010] The bottle unit 2 of this embodiment includes a mixing device 4 and a bottle container 5 containing tire repair fluid. The bottle container 5 has, for example, an opening 5a for containing the tire repair fluid inside the bottle container 5. The mixing device 4 is preferably attached to the opening 5a. Figure 1 shows the bottle container 5 in an upright position with the opening 5a facing downwards.

[0011] The mixing device 4 is suitably used for mixing tire repair fluid and compressed air. The mixing device 4 of this embodiment includes a mixing chamber 6, a first inlet 7 for supplying compressed air to the mixing chamber 6, a second inlet 8 for supplying tire repair fluid to the mixing chamber 6, and an outlet 9 for discharging the mixture of tire repair fluid and compressed air from the mixing chamber 6. With such a mixing device 4, the mixing chamber 6 is repeatedly subjected to positive and negative pressure states due to the pulsation of the compressed air supplied from the compressor 3, allowing the tire repair fluid to drip into the mixing chamber 6.

[0012] Figure 2 is a schematic diagram of the mixing device 4 of this embodiment in an upright state with the bottle container 5 facing downwards. As shown in Figures 1 and 2, the mixing chamber 6 of this embodiment includes a deposit section 6a for depositing aggregates contained in the tire repair fluid. The deposit section 6a of this embodiment is formed between the second inlet 8 and the outlet 9.

[0013] In this mixing device 4, the puncture repair fluid dripped from the second inlet 8 is agitated in the mixing chamber 6 and discharged from the outlet 9. Before the fluid comes into contact with the accumulation section 6a, the aggregates contained in the puncture repair fluid can be deposited. Therefore, the mixing device 4 of this embodiment can prevent the flow path from narrowing due to the accumulation of aggregates flowing into the outlet 9, and puncture repair can be performed in a short time.

[0014] In a more preferred embodiment, the mixture is an aerosol of tire repair fluid and compressed air. Such a tire repair kit 1 can efficiently repair the punctured area with a small amount of tire repair fluid, and can reduce the impact on sound-absorbing materials, sensors, etc., even if the tire T has sound-absorbing materials, sensors, etc., placed inside the tire T.

[0015] The puncture repair liquid preferably contains at least glycol. Examples of glycol include ethylene glycol, 1,3-propanediol, propylene glycol, and the like. Such a puncture repair liquid is suitable for efficiently repairing a punctured portion even when a small amount is injected as an aerosol into a punctured tire T.

[0016] The first inlet 7 supplies compressed air to the mixing chamber 6 in the first flow direction a1, for example. The outlet 9 discharges the mixture in the second flow direction a2, for example. The first flow direction a1 and the second flow direction a2 in the present embodiment are parallel to each other and opposite in direction. Such a mixing device 4 can diffuse the compressed air throughout the mixing chamber 6 and can uniformly mix the puncture repair liquid and the compressed air.

[0017] The deposition portion 6a is preferably formed around the outlet 9. Such a deposition portion 6a can surely deposit the aggregates contained in the puncture repair liquid and can further suppress the aggregates from flowing into the outlet 9.

[0018] The deposition portion 6a of the present embodiment protrudes from the surface 6b where the outlet 9 of the mixing chamber 6 communicates. The deposition portion 6a is formed in a thin plate shape, for example. Such a deposition portion 6a can efficiently deposit the aggregates flowing into the outlet 9.

[0019] As shown in FIG. 2, the protruding height h1 of the deposition portion 6a from the surface 6b is preferably 0.50 to 0.85 times the height h2 of the mixing chamber 6 in the protruding direction. Since the protruding height h1 of the deposition portion 6a is 0.50 times or more the height h2 of the mixing chamber 6, the aggregates contained in the puncture repair liquid can be surely deposited, and the aggregates can be more surely suppressed from flowing into the outlet 9. Since the protruding height h1 of the deposition portion 6a is 0.85 times or less the height h2 of the mixing chamber 6, the mixture of the compressed air and the puncture repair liquid can smoothly move in the mixing chamber 6, which helps to perform puncture repair in a short time.

[0020] Figure 3 is a cross-sectional view taken along line A-A of Figure 1. As shown in Figure 3, the longitudinal length w1 perpendicular to the protruding direction of the deposition portion 6a is preferably 1.6 to 3.0 times the maximum opening width w2 of the outlet 9. By having the length w1 of the deposition portion 6a be 1.6 times or more the maximum opening width w2 of the outlet 9, the aggregates contained in the puncture repair liquid can be reliably deposited, and it is possible to more reliably suppress the aggregates from flowing into the outlet 9. By having the length w1 of the deposition portion 6a be 3.0 times or less the maximum opening width w2 of the outlet 9, the mixture of compressed air and the puncture repair liquid can move smoothly within the mixing chamber 6, which helps to perform puncture repair in a short time.

[0021] The thickness t of the thin plate-shaped deposition portion 6a is preferably 1.0 to 2.0 mm. Such a deposition portion 6a can suppress the aggregates from flowing into the outlet 9 without hindering the smooth movement of the mixture of compressed air and the puncture repair liquid within the mixing chamber 6. In Figure 3, the deposition portion 6a is formed in an arc shape, but the deposition portion 6a is not limited to such a form and may be formed, for example, in a straight line shape.

[0022] As shown in Figure 1, the mixing device 4 includes, for example, a first member 10 attached to the mouth portion 5a of the bottle container 5 and a second member 11 attached to the first member 10. The first member 10 is preferably screwed to the mouth portion 5a. The space between the first member 10 and the mouth portion 5a is sealed, for example, by a first seal member 12.

[0023] Such a first member 10 is easy to attach to the bottle container 5 and also has excellent airtightness after attachment. The attachment of the first member 10 to the bottle container 5 is not limited to such a form, and for example, a retaining structure using an elastic body may be adopted.

[0024] The first component 10 preferably has a breaking portion 13 for breaking a film (not shown) that seals the mouth 5a of the bottle container 5 when not in use. Such a mixing device 4 can be attached to the bottle container 5 to release the seal on the bottle container 5. Furthermore, since the bottle container 5 is sealed with a film, the tire repair fluid can be stored for a long period of time without deterioration.

[0025] The first member 10 of this embodiment has a wall portion 14 provided with a second inlet 8. The wall portion 14 is formed, for example, in the shape of a thin plate. The second inlet 8 is, for example, at least one hole provided in the wall portion 14. The wall portion 14 is not limited to this configuration, and various configurations can be adopted as long as the second inlet 8 is provided. The position of the wall portion 14 may be changed, for example, depending on the usage conditions. With such a first member 10, the size of the mixing chamber 6 can be changed by changing the position of the wall portion 14, making design changes easy.

[0026] The second member 11 is preferably screwed to the first member 10. The space between the first member 10 and the second member 11 is sealed, for example, by a second sealing member 15. The mixing chamber 6 is formed by combining the first member 10 and the second member 11. For this reason, it is preferable that the first member 10 and the second member 11 are assembled in advance before the first member 10 is attached to the bottle container 5. However, the attachment of the first member 10 and the second member 11 is not limited to this manner, and for example, an elastic retaining structure may be used, or they may be integrated in a way that makes them impossible to disassemble by press-fitting, bonding, welding, etc.

[0027] The second member 11 of this embodiment has a surface 6b on which a first inlet 7, an outlet 9, and an accumulation section 6a are provided. Preferably, the accumulation section 6a is formed between the first inlet 7 and the outlet 9. Such a mixing device 4 can efficiently mix the tire repair fluid and compressed air, and can also suppress the flow of aggregates contained in the tire repair fluid into the outlet 9.

[0028] In the mixing device 4 of this embodiment, with the bottle container 5 in an upright position with its opening 5a facing downwards, the first inlet 7 and outlet 9 are located below, and the second inlet 8 is located above. The first inlet 7 is located, for example, in the center of the mixing chamber 6. The second inlet 8 and outlet 9 are preferably located on either side of the first inlet 7. Such a mixing device 4 is useful for efficiently mixing tire repair fluid and compressed air.

[0029] The first inlet 7 communicates with the mixing chamber 6, for example, with a first opening area S1. The second inlet 8 communicates with the mixing chamber 6, for example, with a second opening area S2. The first opening area S1 is preferably 1.5 to 15.5 times the second opening area S2. By having the first opening area S1 be 1.5 to 15.5 times the second opening area S2, the ratio of tire repair fluid to compressed air can be maintained within an appropriate range.

[0030] From this perspective, the first opening area S1 is more preferably 1.5 to 13.0 times the second opening area S2, and even more preferably 1.5 to 10.0 times the second opening area S2. Such a mixing device 4 can maintain the ratio of tire repair fluid to compressed air within a more appropriate range.

[0031] The second entrance 8 may be, for example, a plurality of holes provided in the wall portion 14. In this embodiment, when the second entrance 8 is a plurality of holes, the second opening area S2 is the sum of the opening areas of each of the plurality of holes.

[0032] The shape of the hole in the second inlet 8 is not particularly limited and can be appropriately selected from, for example, a circular shape, an elliptical shape, a polygonal shape, etc. If the second inlet 8 has multiple holes, all the holes may have the same shape, or each hole may have a different shape.

[0033] Figure 4 is a schematic diagram of the mixing device 24 of the second embodiment in an upright state with the bottle container 5 facing downwards. As shown in Figure 4, the mixing device 24 of the second embodiment includes a mixing chamber 26, a first inlet 27, a second inlet 28, and an outlet 29. The functions of the mixing chamber 26, the first inlet 27, the second inlet 28, and the outlet 29 are the same as those of the mixing chamber 6, the first inlet 7, the second inlet 8, and the outlet 9 described above, and their explanation is omitted.

[0034] The mixing chamber 26 of the second embodiment includes a deposit section 26a for depositing aggregates contained in the tire repair fluid. The deposit section 26a of the second embodiment is formed between the second inlet 28 and the outlet 29. In the mixing device 24, the first flow direction a1 and the second flow direction a2 are parallel to each other and have the same orientation. Such a mixing device 24 allows compressed air to diffuse into the mixing chamber 26 and be discharged smoothly, which is useful for quick tire repair.

[0035] In the upright position of the bottle container 5 with its mouth 5a facing downwards (as shown in Figure 1), it is desirable that the outlet 29 be located above the first inlet 27. In the second embodiment, the second inlet 28, outlet 29, and accumulation section 26a are provided on the upper surface of the mixing chamber 36. Such a mixing device 24 can cause aggregates contained in the tire repair fluid to accumulate on the lower side of the mixing chamber 26 or in the accumulation section 26a, thereby more reliably suppressing the flow of aggregates into the outlet 29.

[0036] Figure 5 is a conceptual cross-sectional view of a tire repair kit 31 according to a third embodiment. As shown in Figure 5, the tire repair kit 31 according to the third embodiment includes a bottle unit 32 and a compressor 3 for supplying compressed air.

[0037] The bottle unit 32 of the third embodiment includes a mixing device 34 and a bottle container 35 containing tire repair fluid, similar to the bottle unit 2 described above. The bottle container 35 has, for example, an opening 35a for containing the tire repair fluid inside the bottle container 35. The mixing device 34 is preferably attached to the opening 35a.

[0038] The mixing apparatus 34 of the third embodiment includes a mixing chamber 36, a first inlet 37, a second inlet 38, and an outlet 39. The functions of the mixing chamber 36, the first inlet 37, the second inlet 38, and the outlet 39 are the same as those of the mixing chamber 6, the first inlet 7, the second inlet 8, and the outlet 9 described above, and their description is omitted.

[0039] The mixing chamber 36 of the third embodiment, like the mixing chamber 6 described above, includes a deposit section 36a for depositing aggregates contained in the tire repair fluid. The deposit section 36a of the third embodiment, like the deposit section 36a described above, is formed between the second inlet 38 and the outlet 39.

[0040] The mouth portion 35a of the bottle container 35 in the third embodiment has a wall portion 40 on which a second inlet 38 is provided. The mixing device 34 in the third embodiment is formed inside the mouth portion 35a. That is, although the wall portion 40 is provided inside the mouth portion 35a, it is a component of the mixing device 34.

[0041] The mixing device 34 of the third embodiment includes, for example, a connecting member 41 that is attached to the mouth 35a of the bottle container 35. Preferably, the connecting member 41 is screwed to the mouth 35a. The space between the connecting member 41 and the mouth 35a is sealed by, for example, a sealing member 42.

[0042] The bottle container 35 has, for example, a film (not shown) for sealing the opening 5a when not in use. The accumulation section 36a of the third embodiment has a function to break the film when the connecting member 41 is screwed to the opening 35a. Such a mixing device 34 can be attached to the bottle container 35 to release the seal of the bottle container 35. Furthermore, since the bottle container 35 is sealed with a film, the tire repair fluid can be stored for a long period of time without deterioration.

[0043] In the third embodiment of the tire repair kit 31, the mixing chamber 36 may be filled with tire repair fluid during storage. However, the tire repair fluid in the mixing chamber 36 is first discharged by compressed air, and then a mixture of the dripped tire repair fluid and compressed air can be generated.
