  2. The bottle set (2) according to claim 1, wherein the first breaking portion (11) and the second breaking portion (12) have the same structure.
  3. The bottle set (2) according to claim 1 or 2, wherein the third flow passage (10) is at least one hole having a circular cross-section, and the third flow passage (10) has a diameter (d) of 3 mm or smaller.
  4. The bottle set (2) according to any one of claims 1 to 3, wherein the mixing chamber (9) aerosolizes at least a part of the mixture.
  5. The bottle set (2) according to any one of claims 1 to 4, wherein the puncture repair liquid (R) has a viscosity of 100 mPa·s or lower at 25°C and has a viscosity of 400 mPa·s or higher at -30°C.
  6. A puncture repair kit (1) comprising: the bottle set (2) according to any one of claims 1 to 5; and a compressor (3) for supplying the compressed air (A).

Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a bottle set used for filling a punctured object with a puncture repair liquid and compressed air, and a puncture repair kit including the bottle set. Background Art Hitherto, a puncture repair kit for repairing a punctured tire has been known. For example, Japanese Laid-Open Patent Publication No. 2017-056662 proposes a puncture repair kit for repairing a punctured tire by sequentially injecting a puncture repair liquid and compressed air into the punctured tire using compressed air from a compressor. However, the puncture repair kit of Japanese Laid-Open Patent Publication No. 2017-056662 tends to take a long time to close a punctured part with the puncture repair liquid, since the compressed air is injected after the puncture repair liquid is injected. A bottle set in accordance with the preamble of claim 1 is known from US 8,631,840 B2. Related bottle sets are described in EP 4 257 346 A1 (document according to Article 54(3) EPC) and EP 4 261 023 A1 (document according to Article 54(3) EPC). The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a bottle set and a puncture repair kit for performing puncture repair in a short time. SUMMARY OF THE INVENTION The present invention is directed to a bottle set used for filling a punctured object with a puncture repair liquid and compressed air, the bottle set including: a container for containing the puncture repair liquid; a cap member attached to the container; and an adapter member attachable between the container and the cap member, wherein the cap member has a first flow passage for supplying the compressed air, and a second flow passage for discharging the puncture repair liquid and the compressed air, the adapter member has a mixing chamber for producing a mixture of the puncture repair liquid and the compressed air when the adapter member is attached to the cap member, and a third flow passage for supplying the puncture repair liquid to the mixing chamber, and the first flow passage supplies the compressed air into the container when the cap member is directly attached to the container, and supplies the compressed air into the mixing chamber when the cap member is attached to the container via the adapter member. The container includes an opening portion to which the cap member or the adapter member is attached. The opening portion has a film for holding the puncture repair liquid in an airtight manner. The cap member has a first breaking portion which breaks the film when the cap member is attached to the opening portion. The adapter member has a second breaking portion which breaks the film when the adapter member is attached to the opening portion. An opening area of the film broken by the first breaking portion or the second breaking portion is larger than a cross-sectional area of the third flow passage. As a result of having the above-described configuration, the bottle set of the present invention allows puncture repair to be performed in a short time. According to an embodiment of the invention, the first breaking portion and the second breaking portion have the same structure. According to an embodiment of the invention, the third flow passage is at least one hole having a circular cross-section, and the third flow passage has a diameter of 3 mm or smaller. According to an embodiment of the invention, the mixing chamber aerosolizes at least a part of the mixture. According to an embodiment of the invention, the puncture repair liquid has a viscosity of 100 mPa·s or lower at 25°C and has a viscosity of 400 mPa·s or higher at -30°C. According to another aspect of the invention, a puncture repair kit includes the bottle set according to the invention or any of its embodiments and a compressor for supplying the compressed air.
