A flat tire repair liquid container is provided with: a closing stopper, which is formed from a non-elastomer material and is capable of sliding inside a flow channel; and a sealing member, which is formed from an elastomer material, is disposed in a ring shape conforming to an inner wall surface of a flow channel, closes a gap between the closing stopper and the flow channel, and holds the closing stopper at a predetermined position. During storage, the closing stopper is engaged with the sealing member to close the flow channel. During flat tire repair work, the closing stopper is pushed out from the sealing member by pressure inside the container and moved toward the outer side of the container in the flow channel to open the flow channel. |

1. A flat tire repair liquid container comprising:
a container main body including a container body and an opening, the container body storing a flat tire repair liquid; a cap including a mounting portion, a dispensing portion, and a flow channel, the mounting portion being mounted to the opening during flat tire repair work, the dispensing portion being configured to dispense the flat tire repair liquid outside of the container, the flow channel connecting the mounting portion and the dispensing portion; and a stopping mechanism including: a closing stopper formed from a resin that is a non-elastomer material, the closing stopper being capable of sliding within the flow channel, a sealing member formed from an elastomer material, the sealing member being disposed in a ring shape conforming to an inner wall surface of the flow channel and configured to close a gap between the closing stopper and the flow channel and to hold the closing stopper at a predetermined position, and a shape-retaining member configured to combine with the closing stopper during storage so as to keep the closing stopper in a restrained state in which the closing stopper does not disengage from the sealing member and to disengage from the closing stopper during flat tire repair work so as to release the closing stopper from the restrained state; wherein the closing stopper includes a stopper portion that blocks the flow channel, a recessed portion that is adjacent to a side of the stopper portion positioned toward an inner side of the container and engages with the sealing member, and a plurality of holding portions that are adjacent to a side of the recessed portion positioned toward the inner side of the container, project toward the inner side of the container from a periphery of an end surface of the closing stopper positioned toward the inner side of the container, and hold the shape-retaining member; the shape-retaining member includes a body portion held by the holding portions when closed, a recessed portion surrounded by tip portions of the holding portions when open, an outer stopper having a diameter greater than the body portion in an end portion of the shape-retaining member positioned toward an outer side of the container, and an inner stopper having a diameter greater than an imaginary circle inscribed in the tip portions of the holding portions of the closing stopper in an end portion of the shape-retaining member positioned toward the inner side of the container; and during storage, the closing stopper that is in the restrained state engages with the sealing member and closes the flow channel, during tire repair work, the closing stopper that has been released from the restrained state by the shape-retaining member disengaging from the holding portions and the holding portions deforming toward a center of the closing stopper is pushed out from the sealing member by pressure inside the container and moved toward the outer side of the container in the flow channel to open the flow channel. |
