Problems solved by technology

Such a methodology has the deficiencies that the tire must be removed from the vehicle and the location of the puncture found.
Rotation of the tire causes the sealant to spread over the inner surface of the tread area, sealing the leak.
The quantity of sealant in the can is often limited, and there is a limited amount of compressed gas in the container to drive the fluid.
Often such containers do not have sufficient contents to re-inflate a punctured tire su

Embodiment Construction

[0014]With initial reference to FIG. 1, the present invention comprises a container assembly 10 for a quantity of sealant fluid 12 intended to be injected into tire 14 to either seal a pre-existing puncture hole or to serve as a prophylactic against loss of air from the tire through a subsequent puncture. The sealant may be of a type generally known in the trade, including vinyl or cellulose-based types, with binders and clotting agents of the general type known in the art. The fluid contents 12 of the container assembly are directed upward through dip tube 16 and delivered to the interior of the tire through outlet tube 18, which terminates in a connector 20 of known construction that attaches to the inflation valve stem of the tire. The air space 22 above the sealant fluid 12 in the container assembly is pressurized to drive the fluid through the dip tube and outlet tube into the tire. The internal container pressure is developed by a suitable source of compressed gas, such as air...

Abstract

A tire-sealing apparatus for injecting a sealing composition into a vehicle tire either as a prophylactic or for sealing an existing leak is in the form of a pressurizeable container for a flowable sealant compound. An inlet is provided for introducing compressed gas into the container to pressurize its contents. An outlet line is also provided to deliver the sealant into a tire, the pressurized gas acting on contents of the container and providing the motive force for the delivery. A dip tube extends into the compound and is coupled to a one-way valve to provide a controlled flow of the compound from the container into the tire while preventing back pressure of the tire from either delivering air or compound back into the container. A passageway between the outlet tube and an interior of the container is provided to allow a flow of compressed gas within the container into the outlet tube along with the sealant.

Description

[0001]The present invention relates to an apparatus and method for dispensing a measured amount of a fluid under pressure and in particular to an apparatus for dispensing tire sealant into a vehicle tire. Applicants claim the benefit of U.S. Provisional Application 60 / 983,423 filed Oct. 29, 2007, the contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]Vehicle tire repair technology is well developed. In one well known aspect, a tire, such as an automobile or truck tire, damaged and deflated by a puncture, such as by a nail, is demounted from the vehicle and the puncture point located. An elastomeric plug is inserted into the puncture hole creating an airtight seal. The tire can then be re-inflated and re-installed on the vehicle. Such a methodology has the deficiencies that the tire must be removed from the vehicle and the location of the puncture found. When the puncture-causing object no longer is in the tire some degree of skill and care is req...
