Flat tire repair liquid container
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;
a closing stopper formed from a non-elastomer material, the closing stopper being capable of sliding within the flow channel; and
a seal formed from an elastomer material, the seal 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;
wherein
during storage, the closing stopper and the seal engage with one another to close the flow channel, and during flat tire repair work, the closing stopper is pushed out from the seal by pressure inside the container and moved toward an outer side of the container in the flow channel to open the flow channel.
2. The flat tire repair liquid container according to claim 1 , wherein
the closing stopper includes a recessed portion that engages with the seal,
a diameter R A of the recessed portion is smaller than a diameter R B of an end of the closing stopper positioned toward the outer side of the container and a diameter R C of an end of the closing stopper positioned toward an inner side of the container, and
the diameter R A is greater than an inner diameter r of the seal.
3. The flat tire repair liquid container according to claim 2 , wherein the flow channel includes a vertical hole section extending in a sliding direction of the closing stopper and a horizontal hole section extending in a direction that intersects with the vertical hole section, and
during flat tire repair work, the end of the closing stopper positioned toward the inner side of the container is located on the outer side of the container with respect to a center of the horizontal hole section.
4. The flat tire repair liquid container according to claim 3 , wherein a housing portion that houses the closing stopper during flat tire repair work is provided on an end of the vertical hole section positioned toward the outer side of the container.
5. The flat tire repair liquid container according to claim 4 , further comprising a guide for moving the closing stopper parallel to the flow channel.
6. The flat tire repair liquid container according to claim 5 , wherein upon the pressure inside the container reaching 150 kPa or higher, the closing stopper is pushed out from the seal and moved toward the outer side of the container in the flow channel.
7. A method for injecting flat tire repair liquid using the flat tire repair liquid container described in claim 6 , the method comprising the steps of:
connecting the flat tire repair liquid container to a compressor; and
pressurizing an inside of the container to 150 kPa or higher such that
the closing stopper is pushed out from the seal and moved toward the outer side of the container in the flow channel to open the flow channel.
8. The flat tire repair liquid container according to claim 1 , wherein the flow channel includes a vertical hole section extending in a sliding direction of the closing stopper and a horizontal hole section extending in a direction that intersects with the vertical hole section, and
during flat tire repair work, an end of the closing stopper positioned toward an inner side of the container is located on the outer side of the container with respect to a center of the horizontal hole section.
9. The flat tire repair liquid container according to claim 8 , wherein a housing portion that houses the closing stopper during flat tire repair work is provided on an end of the vertical hole section positioned toward the outer side of the container.
10. The flat tire repair liquid container according to claim 1 , further comprising a guide for moving the closing stopper parallel to the flow channel.
11. The flat tire repair liquid container according to claim 1 , wherein upon the pressure inside the container reaching 150 kPa or higher, the closing stopper is pushed out from the seal and moved toward the outer side of the container in the flow channel.
12. A method for injecting flat tire repair liquid using the flat tire repair liquid container described in claim 1 , the method comprising the steps of:
connecting the flat tire repair liquid container to a compressor; and
pressurizing an inside of the container to 150 kPa or higher such that
the closing stopper is pushed out from the seal and moved toward the outer side of the container in the flow channel to open the flow channel.
