ABSTRACT:
A very simple and economic method and closure for quickly repairing a puncture in a vehicle tire utilizes a screw having a concave slot beneath its head. A sealing material such as an adhesive rubber is placed in the slot and is used to seal the hole when the sealing screw is threaded into the hole. The design provides easy, quick, efficient and very low cost repair for a puncture in a tire, not only for temporary repair but for long term repairs. The design is simple and includes only two parts: a screw having a spiral convex, or thread which affixes the screw in the tire and which further includes a concave slot under the screw head, and a sealing material such as adhesive or sticky rubber which is secured in the slot. The screw body is fixed in the tire hole and the head presses the sealing material onto the hole.
