[0015] Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

[0016] Figure 1 FIG. 2 is a cross-sectional view showing the tire blowout repair kit 1 according to the present embodiment. Figure 1 As shown, the flat tire repair kit 1 is suitable for use in filling a flat tire repair fluid R and compressed air A into an object T such as a flat tire.

[0017] The flat tire repair kit 1 of the present embodiment includes: a bottle unit 2 for discharging a mixture of a flat tire repair liquid R and compressed air A toward an object T; and a compressor 3 for supplying compressed air A. The bottle unit 2 of the present embodiment includes: a mixing device 4 for mixing the flat tire repair liquid R and the compressed air A; and a container 5 for containing the flat tire repair liquid R. The mixing device 4 includes, for example, an adapter member 6 mounted on the container 5, and a cap member 7 mounted on the adapter member 6.

[0018] Such a bottle unit 2 facilitates the installation of the mixing device 4 and the container 5, which helps to shorten the time required for repairing a flat tire. In addition, the mixing device 4 can pre-mix the flat tire repair liquid R and the compressed air A before filling the object T, which can shorten the time required for repairing a flat tire. In addition, the mixing device 4 is not limited to such a form, and for example, it can also be an integrally molded product in which the adapter component 6 and the cover component 7 are integrated.

[0019] The container 5 has, for example, a mouth 5a for containing the flat tire repair liquid R in the container 5. The container 5 contains the flat tire repair liquid R in the container 5 through, for example, the mouth 5a. The mouth 5a has, for example, a film (not shown) for airtightly retaining the contained flat tire repair liquid R.

[0020] The mixing device 4 is preferably attached to the mouth 5a of the container 5. Such a container 5 does not need to form a separate outlet for taking out the flat tire repair liquid R, which contributes to a reduction in manufacturing cost.

[0021] The mixing device 4 of the present embodiment includes a mixing chamber 8 having a space for mixing the flat tire repair liquid R and the compressed air A. The mixing chamber 8 includes, for example, a top surface 8a located at the top when the mixing device 4 is mounted on the container 5 and used for flat tire repair, a bottom surface 8b located at the bottom, and a side surface 8c connecting the top surface 8a and the bottom surface 8b. The mixing chamber 8 has, for example, a cylindrical space in which the top surface 8a and the bottom surface 8b are circular.

[0022] The mixing device 4 of this embodiment includes a first inlet 9 for supplying compressed air A to the mixing chamber 8 and a second inlet 10 for supplying the flat tire repair liquid R to the mixing chamber 8. The first inlet 9 is communicated with, for example, a compressor 3 as a compressed air source. The second inlet 10 is communicated with, for example, a container 5 containing the flat tire repair liquid R.

[0023] Such a mixing device 4 can generate a mixture by causing the mixing chamber 8 to repeatedly be in a positive pressure state and a negative pressure state by pulsating the compressed air A supplied from the compressor 3 , thereby causing the flat tire repair fluid R in the container 5 to drip from the second inlet 10 into the mixing chamber 8 .

[0024] The mixing device 4 preferably includes an outlet 11 for discharging the mixture of the flat tire repair liquid R and the compressed air A from the mixing chamber 8. Such a mixing device 4 can supply the mixture of the flat tire repair liquid R and the compressed air A to the object T, and can shorten the time required for flat tire repair compared to the case where the flat tire repair liquid R and the compressed air A are supplied sequentially.

[0025] The first inlet 9 and the outlet 11 are provided, for example, in the cover member 7. The first inlet 9 and the outlet 11 of this embodiment are provided on the bottom surface 8b. The second inlet 10 is provided, for example, in the partition wall 6a of the adapter member 6. The second inlet 10 of this embodiment is provided on the top surface 8a.

[0026] Such a mixing device 4 discharges the mixture of the puncture repair fluid R dripping from the second inlet 10 located at the upper side and the compressed air A from the outlet 11 located at the lower side, thereby suppressing the accumulation of the dripping puncture repair fluid R and efficiently generating the mixture.

[0027] The mixing chamber 8 may also include, for example, a protrusion 12 protruding from the top surface 8a toward the inside of the mixing chamber 8. For example, a conical shape having the most protruding vertex is suitable as the protrusion 12. Such a protrusion 12 can make the flow inside the mixing chamber 8 directional, and can efficiently discharge the mixture of the flat tire repair fluid R and the compressed air A.

[0028] The mixing chamber 8 may also be formed with a plurality of hemispherical recesses 13, for example, on at least one of the top surface 8a, the bottom surface 8b, and the side surface 8c. Such a plurality of recesses 13 helps to make the flow smooth and shorten the residence time of the mixture in the mixing chamber 8.

[0029] The adapter member 6 is, for example, screwed to both the mouth 5a of the container 5 and the cover member 7. The adapter member 6 and the mouth 5a are preferably sealed by a sealing member 14. The adapter member 6 and the cover member 7 are sealed by, for example, a secondary sealing member 15. Such an adapter member 6 makes it easy to attach to the container 5 and to the cover member 7, and the airtightness after attachment is also excellent.

[0030] In addition, the adapter member 6 may include, for example, a breaking portion (not shown) for breaking a film (not shown) of the mouth portion 5a when being screwed to the mouth portion 5a.

[0031] Figure 2 4 is a top view of the mixing device 4. Figure 1 as well as Figure 2 As shown, the second inlet 10 includes at least one flow path 16 having a slit-like cross section in the longitudinal direction, and in this embodiment, includes one flow path 16. Such a second inlet 10 can suppress clogging of the flow path 16 and efficiently supply the puncture repair fluid R even if the puncture repair fluid R in the container 5 contains rubber lumps as solid matter.

[0032] Furthermore, even when the viscosity of the flat tire repair fluid R increases under low temperature conditions, the second inlet 10 of the present embodiment can supply the flat tire repair fluid R from the slit-shaped flow path 16 and supply it as a mixture to the object T. Therefore, the mixing device 4 of the present embodiment can efficiently repair a flat tire of the object T.

[0033] As a more preferred embodiment, the length L1 of the slit-shaped flow path 16 in the longitudinal direction is preferably 3.0 to 15.0 mm. The length L1 of the flow path 16 is 3.0 mm or more, so that the blockage of the flow path 16 caused by the rubber block can be reliably suppressed. The length L1 of the flow path 16 is 15.0 mm or less, so that the excessive supply of the flat tire repair fluid R that may cause the blockage at the outlet 11 can be suppressed. Here, the length L1 of the flow path 16 is the shortest length along the longitudinal direction.

[0034] The width W1 of the slit-shaped flow path 16 in a direction perpendicular to the longitudinal direction is preferably 0.3 to 1.0 mm. The width W1 of the flow path 16 is 0.3 mm or more, so it is easy to process and helps to reduce the manufacturing cost. The width W1 of the flow path 16 is 1.0 mm or less, so it is possible to suppress the excessive supply of the flat tire repair fluid R that may cause clogging at the outlet 11. Here, the width W1 of the flow path 16 is the shortest width in the direction perpendicular to the longitudinal direction.

[0035] The slit-shaped flow path 16 of this embodiment extends over the entire region with a constant flow path cross-sectional area. Such a flow path 16 is easy to process, can reduce manufacturing costs, and can also easily adjust the supply amount of the flat tire repair fluid R.

[0036] The flow path 16 of this embodiment is a slit extending linearly in the longitudinal direction. Such a flow path 16 is easy to process and can reduce the manufacturing cost.

[0037] Figure 3 FIG. 2 is a top view of a mixing device 20 according to a second embodiment. The same elements as those in the above-mentioned embodiment are denoted by the same reference numerals, and their descriptions are omitted. Figure 3 As shown, the mixing device 20 of the second embodiment is similar to the above-mentioned mixing device 4, and is provided with a mixing chamber 8 ( Figure 1 As shown in the figure, a second inlet 21 is provided to supply a flat tire repair fluid R.

[0038] The second inlet 21 of the second embodiment has a flow path 22 having a slit-like cross section in the longitudinal direction, similarly to the second inlet 10 described above. Figure 1 The tire puncture repair fluid R in the embodiment shown in the figure contains rubber pieces as solid matter, which can also suppress the clogging of the flow path 22 and efficiently supply the tire puncture repair fluid R.

[0039] Further, similarly to the second inlet 10 , the second inlet 21 of the second embodiment can supply the flat tire repair fluid R from the slit-shaped flow path 22 and supply the flat tire repair fluid R to the object T as a mixture even when the viscosity of the flat tire repair fluid R increases under low temperature conditions.

[0040] The flow path 22 may be, for example, a slit extending in a curved or bent shape in the longitudinal direction. The flow path 22 of the second embodiment is a slit extending in an arc shape in the longitudinal direction. Such a flow path 22 can be directed to the side 8c ( Figure 1 Since the puncture repair liquid R is supplied near the mixing chamber 8, the dispersibility of the puncture repair liquid R in the mixing chamber 8 is excellent, which helps to efficiently generate the mixture.

[0041] Figure 4 FIG. 2 is a partially cutaway perspective view of a mixing device 30 according to a third embodiment. The same elements as those in the above-mentioned embodiment are denoted by the same reference numerals, and their descriptions are omitted. Figure 4 As shown, the mixing device 30 of the third embodiment includes a second inlet 31 for supplying the flat tire repair fluid R to the mixing chamber 8 similarly to the above-mentioned mixing device 4 .

[0042] The second inlet 31 of the third embodiment has a flow path 32 having a slit-shaped cross section in the longitudinal direction, similarly to the second inlet 10 described above. Figure 1 The tire puncture repair fluid R in the embodiment shown in the figure contains rubber pieces as solid matter, which can also suppress the clogging of the flow path 32 and efficiently supply the tire puncture repair fluid R.

[0043] Further, similarly to the second inlet 10 described above, the second inlet 31 of the third embodiment can supply the flat tire repair fluid R from the slit-shaped flow path 32 and supply the flat tire repair fluid R to the object T as a mixture even when the viscosity of the flat tire repair fluid R increases under low temperature conditions.

[0044] The flow path 32 of the third embodiment includes: a first portion 32a opened to the mixing chamber 8 with a first flow path cross-sectional area S1, and a second portion 32b having a second flow path cross-sectional area S2 larger than the first flow path cross-sectional area S1 above the first portion 32a. The flow path 32 preferably includes a step portion 32c that discontinuously changes the flow path cross-sectional area between the first portion 32a and the second portion 32b.

[0045] Such a flow path 32 generates a pressure loss in the flow path 32, and thus the flow rate of the puncture repair liquid R can be suppressed, and the puncture repair liquid R can be supplied slowly. Thus, the second inlet 31 can optimize the supply amount of the puncture repair liquid R to the mixing chamber 8 per hour, suppress the excessive supply of the puncture repair liquid R to the mixing chamber 8, and suppress the retention of the dripping puncture repair liquid R.

[0046] The first portion 32a of the third embodiment extends with a constant first flow path cross-sectional area S1. Preferably, the second portion 32b extends with a constant second flow path cross-sectional area S2. Such a second inlet 31 is easy to process and can reduce manufacturing costs.

[0047] The second flow path cross-sectional area S2 is preferably 150% to 300% of the first flow path cross-sectional area S1. Since the second flow path cross-sectional area S2 is 150% or more of the first flow path cross-sectional area S1, pressure loss can be reliably generated in the flow path 32. Since the second flow path cross-sectional area S2 is 300% or less of the first flow path cross-sectional area S1, the accumulation of the flat tire repair fluid R at the step portion 32c can be suppressed, and the flat tire repair fluid R can be efficiently supplied. From this point of view, the second flow path cross-sectional area S2 is more preferably 180% to 200% of the first flow path cross-sectional area S1.

[0048] The angle θ formed between the outer peripheral surface of the second portion 32b and the step surface of the step portion 32c is preferably 30° to 140°. Since the angle θ between the second portion 32b and the step portion 32c is 30° or more, the stagnation of the flat tire repair fluid R at the step portion 32c can be suppressed, and the flow rate of the flat tire repair fluid R can be suppressed. Since the angle θ between the second portion 32b and the step portion 32c is 140° or less, pressure loss can be reliably generated in the flow path 32. From this point of view, the angle θ between the second portion 32b and the step portion 32c is more preferably 45° to 100°.

[0049] The flow path length L2 of the first portion 32a is preferably 10% to 70% of the total length La of the flow path 32. Since the flow path length L2 of the first portion 32a is 10% or more of the total length La of the flow path 32, pressure loss can be generated in the first portion 32a, and the flow rate of the flat tire repair fluid R in the first portion 32a can be suppressed. Since the flow path length L2 of the first portion 32a is 70% or less of the total length La of the flow path 32, pressure loss can be reliably generated in the step portion 32c. From this point of view, the flow path length L2 of the first portion 32a is more preferably 20% to 40% of the total length La of the flow path 32.

[0050] In addition, flow path 32 for example also can comprise the third part (omitted illustration) whose flow path cross-sectional area is larger than the second flow path cross-sectional area S2 on the upstream side of second part 32b, and flow path cross-sectional area also can change in multistage. In addition, mixing device 30 for example also can be provided with the second next door (omitted illustration) on the upstream side of next door 6a, constitutes the second inlet 31 in multistage.

[0051] The flow path 32 of the third embodiment is a slit extending linearly in the longitudinal direction. Such a flow path 32 is easy to process and can reduce the manufacturing cost.

[0052] Figure 5 FIG. 4 is a top view of a mixing device 40 according to a fourth embodiment. The same elements as those in the above-mentioned embodiments are denoted by the same reference numerals, and their descriptions are omitted. Figure 5 As shown, the mixing device 40 of the fourth embodiment is provided with a device for mixing the mixing chamber 8 ( Figure 4 As shown in the figure, a second inlet 41 is provided to supply the flat tire repair fluid R.

[0053] The second inlet 41 of the fourth embodiment is provided with a flow path 42 having a slit-shaped cross section in the longitudinal direction, similarly to the second inlet 31 described above. Figure 1 The tire puncture repair fluid R in the embodiment shown in the figure contains rubber pieces as solid matter, which can also suppress the clogging of the flow path 42 and efficiently supply the tire puncture repair fluid R.

[0054] Further, similarly to the second inlet 31 described above, the second inlet 41 of the fourth embodiment can supply the flat tire repair fluid R from the slit-shaped flow path 42 and supply the flat tire repair fluid R to the object T as a mixture even when the viscosity of the flat tire repair fluid R increases under low temperature conditions.

[0055] The flow path 42 of the fourth embodiment is similar to the above-mentioned flow path 32 and includes: a first flow path cross-sectional area S1 opening to the mixing chamber 8 ( Figure 4 The flow path 42 preferably includes a first portion 42a (shown in FIG. 1 ) and a second portion 42b having a second flow path cross-sectional area S2 larger than the first flow path cross-sectional area S1 above the first portion 42a. The flow path 42 preferably includes a step portion 42c that discontinuously changes the flow path cross-sectional area between the first portion 42a and the second portion 42b, similarly to the flow path 32 described above.

[0056] Such a flow path 42 can suppress the flow rate of the puncture repair liquid R because of the pressure loss generated in the flow path 42, and can slowly supply the puncture repair liquid R. Thus, the second inlet 41 can optimize the supply amount of the puncture repair liquid R to the mixing chamber 8 per hour, thereby suppressing the excessive supply of the puncture repair liquid R to the mixing chamber 8, and suppressing the retention of the dripping puncture repair liquid R.

[0057] The flow path 42 is similar to the above-mentioned flow path 22, for example, a slit extending in a curved or bent shape in the longitudinal direction. The flow path 42 of the fourth embodiment is a slit extending in an arc shape in the longitudinal direction. Such a flow path 42 can be directed to the side 8c ( Figure 1 Since the puncture repair liquid R is supplied near the mixing chamber 8, the dispersibility of the puncture repair liquid R in the mixing chamber 8 is excellent, which helps to efficiently generate the mixture.

[0058] Figure 6 FIG. 5 is a top view of a mixing device 50 according to a fifth embodiment. The same elements as those in the above-mentioned embodiments are denoted by the same reference numerals, and their descriptions are omitted. Figure 6 As shown, the mixing device 50 of the fifth embodiment is provided with a device for mixing the mixing chamber 8 ( Figure 4 As shown in the figure, a second inlet 51 is provided to supply the flat tire repair fluid R.

[0059] The second inlet 51 includes at least one flow path 52 having a slit-like cross section in the longitudinal direction, and in the fifth embodiment, includes three flow paths 52. Such a second inlet 51 is provided even if the container 5 ( Figure 1 The tire puncture repair fluid R in the embodiment shown in the figure contains rubber pieces as solid matter, which can also suppress the clogging of the flow path 52 and efficiently supply the tire puncture repair fluid R.

[0060] Further, similarly to the second inlet 31 described above, the second inlet 51 of the fifth embodiment can supply the flat tire repair fluid R from the slit-shaped flow path 52 and supply the flat tire repair fluid R to the object T as a mixture even when the viscosity of the flat tire repair fluid R increases under low temperature conditions.

[0061] Each flow path 52 of the fifth embodiment is similar to the above-mentioned flow path 32 and includes: a first flow path cross-sectional area S1 opening to the mixing chamber 8 ( Figure 4 The flow paths 52 are preferably provided with a first portion 52a (shown in FIG. 1 ) and a second portion 52b having a second flow path cross-sectional area S2 larger than the first flow path cross-sectional area S1 above the first portion 52a. Each flow path 52 preferably includes a step portion 52c that discontinuously changes the flow path cross-sectional area between the first portion 52a and the second portion 52b, similarly to the flow path 32 described above.

[0062] Such a flow path 52 generates a pressure loss in the flow path 52, and thus the flow rate of the puncture repair liquid R can be suppressed, and the puncture repair liquid R can be supplied slowly. Thus, the second inlet 51 can optimize the supply amount of the puncture repair liquid R to the mixing chamber 8 per hour, suppress the excessive supply of the puncture repair liquid R to the mixing chamber 8, and suppress the retention of the dripping puncture repair liquid R.

[0063] Each flow path 52 is similar to the above-mentioned flow path 42, and is, for example, a slit extending in an arc shape in the longitudinal direction. Such a flow path 52 can be directed to the side 8c ( Figure 1 Since the puncture repair liquid R is supplied near the mixing chamber 8, the dispersibility of the puncture repair liquid R in the mixing chamber 8 is excellent, which helps to efficiently generate the mixture.

[0064] In addition, each flow path 52 may be, for example, a slit extending in a straight line in the longitudinal direction. In this case, the second inlet 51, for example, each flow path 52 is arranged at a constant distance from the side 8c of the mixing chamber 8 and is formed into an arc shape as a whole, or each flow path 52 may be arranged in a straight line and is formed into a straight line as a whole.

[0065] As mentioned above, although the particularly preferred embodiment of the present invention has been described in detail, the present invention is not limited to the above-mentioned embodiment, but can be modified and implemented in various forms.

[0066] [Example]

[0067] Based on the specifications in Table 1, we have produced Figure 1 to Figure 3 as well as Figure 5 A mixing device with the basic structure shown in FIG. 1 was trial-produced as a comparative example. A mixing device having a second inlet formed of three circular holes was trial-produced. Using the trial-produced mixing device, it was tested whether the flow path was blocked when a tire puncture repair was performed five times at a normal temperature of 20°C to 30°C, and whether the flow path was blocked when a tire puncture repair was performed five times at a low temperature of -10°C.

[0068] The results are as follows: "Yes" indicates that the flow path was blocked even once in the five tests and the puncture repair fluid could not be supplied, and "No" indicates that the flow path was not blocked in all five tests and the puncture repair fluid could be supplied until the end. In addition, "-" indicates the result when no test was performed.

[0069] The test results are shown in Table 1.

[0070]

[0071]

[0072] The test results confirmed that the mixing device of the embodiment did not cause flow path clogging at both normal and low temperatures compared to the comparative example, and that the flat tire repair fluid could be used to the end, thereby efficiently repairing the flat tire of the object.
