Abstract

To enhance storage performance while reducing user's labor of work during puncture repair.SOLUTION: A cap 5 in a bottle unit 2 obtained by attaching the cap 5 to a mouth part 4A of a bottle container 4 comprises a convex part 6 inserted in the mouth part 4A, a first channel 11 for taking compressed air into the bottle container 4, and a second channel 12 for extracting puncture repair liquid and the compressed air from the bottle container 4. The first channel 11 and the second channel 12 each open toward a lower side of the cap 5.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a bottle unit and a puncture repair kit that can reduce the labor of a user at the time of puncture repair and can improve the storage performance.

  In the following Patent Document 1, a bottle unit for puncture repair is proposed. In the proposed bottle unit, a tire connecting hose is wound around and held in advance around the cap. The hose is connected to the connection portion of the second flow path in the cap.

  And at the time of puncture repair, a bottle unit and a compressor are connected by connecting the cap side connection part of the 1st flow path in a bottle unit to a compressor side connection part first (1st process). Thereafter, the hose is rewound from the cap and the tip of the hose is connected to the tire (second step). In this case, since the user needs only two work processes, there is an advantage that workability is excellent.

  However, the hose is wrapped around a relatively small diameter cap. For this reason, the hose tends to be bent and easily brazed, and the number of windings increases. Therefore, it takes time for the user to unwind the hose and connect to the tire. In addition, since the cap is thickened by winding the hose, there is a problem that the bottle unit is bulky and storage property is deteriorated.

  It is conceivable to store the hose in a state where it is removed from the bottle unit. However, in this case, since a step of connecting the hose to the bottle unit is added at the time of puncture repair, the workability is reduced.

JP 2017-222164 A

  The present invention makes it possible, for example, to connect the first flow path and the second flow path provided in the cap to the compressor in one operation, reducing the trouble of the user at the time of puncture repair, and improving the storage performance.
