A tubular structure including an outer tube an inner tube arranged within the outer tube and at least one chamber formed between the outer tube and the inner tube. The tubular structure additionally includes at least one self-healing material arranged in the chamber, wherein the self-healing material is configured to solidify and/or expand upon contact with a reacting material.

Disclosed herein are kits for use in adding degradable foam to a tire, methods for preparing a degradable foam-containing tire, tires containing degradable foam, and methods for degrading the degradable foam in tires containing degradable foam. The degradable foam comprises a combination of (i) at least one di- or polyisocyanate, (ii) at least one polysiloxane diol, at least one polysiloxane diamine, or a combination thereof, and (iii) optionally at least one polyol.

A pneumatic tire is vulcanized using a bladder provided with a coating layer formed of a release agent, and includes a sealant layer disposed on an inner surface of a tread portion in a tire circumferential direction. The amount of silicon of the release agents detected in at least a placement region of the sealant layer by fluorescence X-ray analysis is from 0.1 wt. % to 10.0 wt. %.

A check joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element, at least one cutout, a head, a conical rib, and a neck.

A tire repair device with an inflation compressor and a sealant material canister, and method of operation. A pressure gauge determines a tire inflation pressure, and a controller identities a completion of a sealant injection upon a pressure drop measured at the pressure gauge. The controller is configured to automatically shut off the inflation compressor when a tire pressure meets a predetermined inflation value after the pressure drop.

This invention reveals an uncured pneumatic tire which is comprised of a generally toroidal-shaped supporting carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead, sidewalls extending radially from and connecting said tread to said beads, a sealant layer which is disposed inwardly from the supporting carcass, and an innerliner which is disposed inwardly from the sealant layer, wherein said circumferential tread is adapted to be ground-contacting, and wherein the sealant layer is comprised of polyisobutylene or a butyl rubber, wherein the polyisobutylene or the butyl rubber has a number average molecular weight which is within the range of 30,000 to 100,000.

A pneumatic tire is vulcanized using a bladder provided with a coating layer formed of a release agent, and includes a sealant layer disposed on an inner surface of a tread portion in a tire circumferential direction, the release agent having a thickness of from 0.1 μm to 100 μm in at least a placement region of the sealant layer, detected using an electron microscope.

A method of using a device of inflating and repairing a broken tire contains a step of: placing the device on a ground. The device contains: an accommodation box, a sealant can, a cap, and at least one delivery hose. The accommodation box accommodates an air compressor for compressing airs so as to produce compressed airs. The accommodation box includes a first coupling orifice and a second coupling orifice. The sealant can includes a body in which sealant is received, and the cap is connected on an open end of the body. The cap includes an air inflow tube and a sealant supply tube), and the cap is engaged on the first coupling orifice or the second coupling orifice. The at least one delivery hose includes a first connector and a second connector connected with two components, thus inflating and repairing the broken tire diversely.
