Abstract From the Canadian patent

The improved tire repair device includes a disposable protective tip which protects a plug being inserted into a tubeless tire from damage caused by belts under the tire tread, especially by steel belts. The tip is coneshaped and is optionally constructed of flexible material in a manner which allows the tip to collapse to conform to the size and shape of small injuries to the tire.
