The present invention relates to a plug comprising a porous material. These plugs can be used for sealing a puncture in a tyre. These plugs can allow a consumer to quickly and effectively seal a puncture.

The present disclosure discloses a quick tire repairing nail. The quick tire repairing nail includes a tire repairing screw made of hard materials, at the front end of the tire repairing screw is provided with a sharp portion and at the rear end of the tire repairing screw is provided with a screw head, and a surface of the screw head which is far away from the tire repairing screw is provided with a concave-convex matching structure. The tire repairing nail further includes a sealing sleeve wrapping the outside of the screw head and/or the tire repairing screw, the sealing sleeve is made of soft materials and has a taper structure with a small front end and a bigger rear end.

A plug and tire repair device are for repairing a puncture in a vehicle tire. The device includes an applicator including a stem portion and a tip portion for insertion into a puncture and through a wall of the tire, at least a part of the stem portion and the tip portion having a passage therethough, and a plug. The plug has a plug shaft made of a resilient material, a stopper portion provided at a first end of the plug shaft and a patch portion provided at a second end of the plug shaft opposite the first end, the patch portion having a closed position in which the patch portion is folded around the plug shaft and an open position in which the patch portion is extends outwardly from the plug shaft in a direction substantially perpendicular to the plug shaft. The plug shaft and the patch portion are guidable through the passage in the applicator.

The present invention is directed to a plug for sealing a puncture in a tyre, whereby the plug comprises a head portion and a tail portion, the head portion comprising: a porous material that comprises open pores and capable of absorbing >0.02 grams of water per gram of porous material; and an accelerant selected from the group consisting of a salt, a polar solvent, an acid, and any combinations thereof, wherein the accelerant is retained in the pores of the porous material and is configured to react on contact with a curable sealant selected from the group consisting of anionic stabilized sealants, steric stabilized sealants and anionic colloidal dispersions thereby reducing curing time of the sealant, and wherein the porous material does not comprise the sealant.

The present invention provides a tire repairing plug, a kit comprising a plurality of such plugs with different dimensions and designs to fit different tires and different damages thereon, and a method of using the plug to repair a damaged tire in vehicles such as bicycles, motorcycles, cars, and trucks etc. The plug incudes a cap and an elongated body, and a middle portion of the body is bigger than any other portions of the body. The invention exhibits numerous technical merits such as simpler operation, higher effectiveness and improved reliability in repairing a damaged tire, among others.
