The present invention relates to a non-flammable, anti-corrosive, non-discoloring product which has both penetrating and lubricating characteristics and is prepared with a non-flammable propellant that does not emit volatile organic compounds, but does replace water, and to a process for producing the same.

Non-flammable liquid penetrating lubricant

A product for inflating a pneumatic tire including an enhanced delivery system is disclosed according to the present invention. The tire inflating product includes a container containing a condensed gas and a sealant, and a flexible conduit extending outwardly from a first end of the container in a direction parallel to the longitudinal axis of the container. The free end of the conduit is adapted to be connected to a valve stem of a tire and, typically, includes a threaded coupling with a valve depressor. The container includes a valve assembly on one end for releasing the contents of the container and an actuator is provided for actuating the valve assembly to release the container contents through the conduit.

Tire inflator and sealant product

A combined cap and nozzle for a container is provided, having a skirt, a transverse wall, and having a restricted orifice of small diameter through the wall. A coupling is provided, being preferably standard female threads as used in garden hoses, for attachment with a conduit such as with the male coupling of a garden hose. Water from a residential faucet may be passed through the garden hose and the restricted orifice to impact on and dislodge waste from a body.

Combined can top and nozzle

A new tire sealant and inflator composition is provided, which combines a sealant in an aqueous carrier with a non-flammable, non-ozone depleting propellant/inflator. A preferred composition combines a sealant composition with 1,1,1,2-tetrafluoroethane (134a). In a preferred embodiment, a vapor pressure depressant is combined with the sealant and 134a. A preferred sealant and inflator composition comprises from about 20% to about 80% of 134a, from about 2% to about 10% of a sealer, such as latex, or a polyvinyl acetate emulsion; from about 1% to about 8% of a freezing point depressant, such as an alkylene glycol; from about 0.1% to about 1% of a corrosion inhibitor, such as ammonia; from about 30% to about 70% of a carrier, such as water; and from about 4% to about 40% of a vapor pressure depressant, such as a glycol ether. A preferred vapor pressure depressant is 2-butoxyethanol, and a preferred freezing point depressant is ethylene glycol. Preferably the sealant composition combine with 134a or other non-flammable and non-ozone depleting propellant/inflator is biodegradable.
