The corner sleeve members are installed after the insert members are engaged with the article and are sized to overlap each other when installed on articles within the given dimensional range. The corner sleeve members can thus telescopically expand or contract to different package sizes determined by the enclosed article.

Abstract: A pneumatic insert for a pneumatic tire comprises a generally toroidal shaped hollow member having a pair of annular insert beads with sidewalls extending therefrom joined to an insert crown portion. An annular flap portion is joined to the outer surface of each insert sidewall at the bead area and extends beyond each bead a predetermined amount.The pneumatic insert is disposed in a standard tire and mounted on standard rim. The insert flaps are tucked between the respective insert beads and the bead support surface of the rim to provide a leak-tight seal. When the insert is inflated the insert beads push the respective tire beads against the rim flange. In one embodiment the tire is inflated through an air passage member disposed between the tire and insert beads. In another embodiment the tire is inflated directly through the tire sidewall with a hypodermic needle. The insert inflation chamber and the tire inflation chamber do not communicate and can be inflated to different pressure levels.

Abstract: A pneumatic tire, after manufacture, is provided with a propellant material and a foam forming sealant material in its interior pressurizable space. The propellant and sealant are isolated from each other during normal running conditions of the tire and have no significant effect on the normal running characteristics of the tire. When a tire fails due to a puncture or the like, a loss of tire pressure and/or collapse of the tire structure and/or heat build up in the bead area due to friction permit the propellant and the foam forming materials to interreact.In one embodiment of the invention the propellant and sealant are enclosed in separate chambers of a plurality of dual-chamber containers secured to the bead portion of the tire and/or a rim base. In other embodiments a plurality of mono-chamber containers house one of the materials, the other material being uncontained in the pressurizable space.
