Sealant delivery system
An apparatus including a pouch and a valve stem. The pouch can include a sealant. The valve stem can be fluidly coupled to the pouch.
1. A method, comprising:
securing a sealant delivery device to a rim, wherein the sealant delivery device includes a valve stem fluidly coupled to a pouch at least partially filled with a volume of a tire sealant and a breaching area, wherein the pouch is configured to breach at a predetermined pressure at the breaching area and cause at least a majority of the tire sealant to leave the pouch;
mounting a tire to the rim; and
inflating the pouch using the valve stem to at least the predetermined pressure;
wherein the pouch breaches and releases the tire sealant into the tire.
2. The method of claim 1 , wherein the volume is about 1 fluid ounce to about 4 fluid ounces.
3. The method of claim 1 , wherein the pouch has a diameter of about 0.5 inches to 3 inches, the pouch has a length of about 3 inches to 9 inches, and the tire is a bicycle tire.
4. The method of claim 1 , wherein the pouch comprises a sheet of material bonded to itself to form a chamber.
5. An apparatus, comprising:
a pouch configured to breach at a predetermined pressure at a breaching area of the pouch;
a valve stem fluidly coupled to the pouch; and
a volume of a tire sealant disposed in the pouch;
wherein,
when pressurized air is applied through the valve stem and into the pouch, the pouch is configured to breach at the predetermined pressure at the breaching area;
the valve stem is configured to be a tire valve stem; and
the pouch is configured to fit between a rim and a tire.
6. The apparatus of claim 5 , wherein the pouch comprises an opening comprising at least one of a slit, a bung, or a plastic zipper.
7. The apparatus of claim 5 , wherein the volume is about 1 fluid ounce to about 4 fluid ounces, and the pouch comprises a sheet of material bonded to itself to form a chamber.
8. An apparatus, comprising:
a pouch including a sealant and a breaching area; and
a valve stem fluidly coupled to the pouch;
wherein, when pressurized air is applied through the valve stem and into the pouch, the pouch is configured to breach at the breaching area and cause at least a majority of the sealant to leave the pouch.
9. The apparatus of claim 8 , wherein the pouch comprises a sheet of material bonded to itself to form a chamber.
10. The apparatus of claim 8 , wherein the material is at least one of polyethylene, polypropylene, polystyrene, polyvinyl chloride, polytetrafluoroethylene, or nylon.
11. The apparatus of claim 8 , wherein the pouch is configured to breach at a predetermined pressure of the pressurized air.
12. The apparatus of claim 8 , wherein the predetermined pressure is about 5 pounds per square inch to about 60 pounds per square inch.
13. The apparatus of claim 8 , wherein the valve stem further comprises a valve.
14. The apparatus of claim 13 , wherein the valve comprises at least one of a Schrader valve, a Presta valve, or a tire pressure monitoring system (TPMS) valve.
15. The apparatus of claim 8 , wherein the sealant comprises at least one of latex or glycol.
16. The apparatus of claim 8 , wherein the valve stem further comprises a valve stem support configured to seat the valve stem in a rim.
17. The apparatus of claim 8 , wherein the pouch comprises a plurality of chambers.
18. The apparatus of claim 8 , wherein the valve stem is a tire valve stem and the pouch is configured to fit between a rim and a tire.
19. The apparatus of claim 18 , wherein the pouch has a diameter of about 0.5 inches to about 3 inches, the pouch has a length of about 3 inches to about 9 inches, and the tire is a bicycle tire.
