Definitions

  • This invention relates to a method and apparatus for inflating and sealing an inflatable objects. More particularly, the invention relates to a tire sealant container and a method and apparatus for using the sealant container.
  • Portable tire sealing and inflating devices have been used in emergency by a motorist to inflate and temporarily seal a pneumatic tire with a puncture wound when a service station or other repair facilities is not available to the motorist.
  • the use of such devices typically for an automobile, allows the motorist to drive the vehicle to a convenient location where the punctured or flat tire can be inspected and repaired.
  • the availability of such devices obviates the need for the motorist to remove the flat tire from an automobile and replace it with a spare tire in order to reach a service station to repair the damaged tire. More importantly, such portable devices are extremely desirable if the motorist is stranded in a dangerous situation or if the motorist either does not have a spare tire or is physically unable to replace the flat tire with a spare tire.
  • a portable tire sealing and inflating device includes a conventional aerosol can containing a particular sealant composition which is introduced to the cavity of a flat tire through a valve stem.
  • a length of flexible tubing connects a valve on the can with a threaded nozzle and connector on the remote end for attachment to and activation of the valve stem.
  • the can is supplied with a pedestal valve for activation and dispensing of the contents without flexible tubing.
  • a propellant within the can forces the sealant composition through the opened valve and into the tire. In this way, the tire is inflated and sealed.
  • aerosol which is formed by a sealant composition and a propellant.
  • the aerosol can include a liquefied propellant or a solubilized gas or gaseous mixture.
  • propellants various hydrocarbons and chlorofluorocarbons have been used. It is known that hydrocarbon propellants are extremely flammable, and that chlorofluorocarbon (CFC) propellants have been found to have a detrimental effect on the earth's ozone layer and use thereof has been severely limited. Although some modified chlorofluorocarbons may not have substantial ozone-depleting potential, they may pose other environmental problems.
  • 1,1,2,2-tetrafluroethane has been used as a non-flammable propellant. While not having stratospheric ozone-depletion potential, this extremely stable gas has a very significant global-warming potential (also referred to as the “green-house effect”). It is about 2,250 times as potent as carbon dioxide as a global-warming agent.
  • gas pressure generally is dependent upon the ambient temperature. As the ambient temperature increases, the gas pressure generally increases as well. This could have significant impact on the safety of an aerosol container.
  • a normal storage place for a tire sealing and the inflator device is the trunk of a motor vehicle. The temperature inside the trunk can go beyond 130° F. in a hot climate. Therefore, it is possible that the aerosol can could deform and might even rupture, causing a hazardous explosion. To avoid such situations, most tire sealing and inflating devices are pressurized to a pressure substantially less than 180 psig @ 130° F. Lower propellant pressure usually leads to a lesser amount of the propellant in the aerosol can. Therefore, an alternative design of a tire sealing and inflating device is needed to solve this dilemma.
  • compressed gases e.g., carbon dioxide, nitrous oxide, nitrogen, and air
  • these gases have not been successfully used in aerosol-based tire sealing and inflating devices. This is because relatively little of these gaseous propellants can be compressed into aerosol dispensers (regardless of the content) before the pressure exceeds 180 psig at 130° F.
  • the invention relates to a sealant container which includes: (1) a sealant composition inside the container; (2) an outlet port on the container for connection to an inflatable object; and (3) an inlet port on the container for connection to an external propellant.
  • the sealant container does not include an internal propellant and is under a pressure substantially approximate to the ambient pressure.
  • the outlet port is a dip tube.
  • the invention in another aspect, relates to an apparatus for inflating an inflatable object.
  • the apparatus includes: (1) a sealant container with a sealant composition which is substantially free of an internal propellant; (2) an external propellant; (3) a first means for connecting the sealant container to an external propellant; and (4) a second means for connecting the sealant container to the inflatable object.
  • the external propellant, the sealant container and the inflatable object are connected in such a way that at least a portion of the external propellant passes through the sealant container as it inflates the inflatable object.
  • the invention in still another aspect, relates to a method for inflating an inflatable object with a puncture.
  • the method includes: (1) providing a sealant container with a sealant composition which is substantially free of an internal propellant; (2) connecting the sealant container to the inflatable object; (3) connecting the sealant container to an external propellant; and (4) inflating the inflatable object by the external propellant. At least a portion of the external propellant passes through the sealant container so that the sealant composition is delivered to the puncture by the external propellant.
  • FIG. 1 is a schematic illustrating a tire sealing and inflating device utilizing an inflated tire to inflate a flat tire in accordance with one embodiment of the invention.
  • FIG. 2 is a schematic of a tire sealing and inflating device utilizing an air compressor to inflate a flat tire in accordance with another embodiment of the invention.
  • Embodiments of the invention are based, in part, on the discovery that a punctured tire can be repaired and inflated to a desired pressure by a sealant container which does not include an internal propellant. Instead, the sealant composition inside the sealant container is delivered to the flat tire by an external propellant, which also inflates the flat tire. Because an external propellant is provided to deliver the sealant composition to the tire puncture, it obviates the need for an internal propellant (although its use is not completely precluded). Consequently, aerosol-based formulations become unnecessary.
  • a sealant container for use in connection with an external propellant to inflate and seal a flat tire.
  • the sealant container includes (1) a sealant composition inside the container; (2) an outlet port on the container for connection to an inflatable object; and (3) an inlet port on the container for connection to an external propellant.
  • the outlet port is a dip tube, although other delivery mechanisms may be used.
  • the dip tube is used to allow the sealant composition to be delivered to an inflatable object after the sealant container is connected to an external propellant.
  • the sealant container should not include an internal propellant to any significant amount and be under a pressure substantially approximate the ambient pressure.
  • ambient pressure refers to one atmosphere at about 25° C.
  • an external propellant refers to those propellants used in an aerosol can to deliver a sealant composition and to inflate a tire.
  • an external propellant refers to an external pressure source used to deliver the sealant composition in a sealant container to a punctured tire and to inflate the tire.
  • any gas may be used as an external propellant; but certain preferences exist.
  • non-flammable gases preferably should be used as an external propellant.
  • gases with zero ozone depletion potential should be used.
  • they do not contribute to the green house effect.
  • non-flammable, non-toxic, and environmentally friendly propellants are preferred as an external propellant in embodiments of the invention. They include, but are not limited to, air, nitrogen, carbon dioxide, nitrous oxide, and noble gases. Because compressed air is relatively inexpensive, it is the most preferred external propellant.
  • Embodiments of the invention also provide an apparatus for inflating and sealing an inflatable object.
  • the apparatus includes: (1) a sealant container as described in the above; (2) an external propellant, (3) a first means for connecting the sealant container to an external propellant; and (4) a second means for connecting the sealant container to the inflatable object.
  • the external propellant, the sealant container, and the inflatable object are connected in such a manner that at least a portion of the external propellant passes through the sealant container as it inflates the inflatable object.
  • Any connection devices or means known or unknown in the art may be used to connect the sealant container to an external propellant and to any inflatable object.
  • a flexible hose or a metal tube with a valve with adapters may be used.
  • a method for inflating and sealing an inflatable object includes: (1) providing a sealant container as described in the above; (2) connecting the sealant container to the inflatable object; (3) connecting the sealant container to an external propellant; and (4) inflating the inflatable object by the external propellant.
