Description




BACKGROUND OF INVENTION




The invention relates generally to a pressurized chemical dispensing apparatus, and more particularly to a hand-held apparatus particularly suitable for use in dispensing two-component systems, more particularly urethane foams, wherein the apparatus includes a push button dispensing assembly interconnected to the canister supplies. Optionally the apparatus is contained within a kit which permits one-handed operation.




The use of urethane and similar expandable foams has increased over the years for numerous applications. Urethane foams are well known as having desirable characteristics useful for many applications, such as insulation. Urethane foams are also well known for their compatibility with low cost blowing agents which allow such foams to be applied by way of pressurized containers as well as their natural adhesive qualities which allow such foams to bond excellently to any number of substrates. Typically, urethane foams are the reaction product of two individual components, one being an isocyanate and the other being a resin. These two individual components when reacted together under pressure, give the resultant foam various chemical compositions, each such composition having significant utility in a particular application. Thus, urethane foams may be specially formulated to provide a final foam which is rigid, semi-rigid or flexible.




Closed cell urethane foams have particular utility in building and structural insulation while open cell urethane foams have particular utility in packaging or non-insulating purposes. Regardless of cell structure, two-component urethane foams are typically formed by mixing the two or more individual foam components together when the foam components exit respective supply containers. Individual material supply tubes leading from each foam component container convey the foam components to a foam dispensing apparatus, such as a nozzle.




There are numerous applications in which polyurethane foam is used at a site for any number of applications in addition to its traditional use in the building trades as a source of insulation. Recently polyurethane foam has become used with increasing frequency as a sealant in the building trades for sealing spaces between window and door frames and the like and as an adhesive for glueing flooring and roof tiles and the like. The polyurethane foam for such in-situ applications is typically supplied as a one-component froth foam or a two-component froth foam. A one-component foam means that both the resin and isocyanate for the foam is supplied in a single pressurized container and dispensed from the container through a valve or gun attached to the container. A two-component “froth” foam means that one component is supplied in one pressurized container, typically the “A” container (i.e., polymeric isocyanate, fluorocarbons etc) while the resin is supplied in a second pressurized container, typically the “B” container (i.e., polyols, catalyst, flame retardants etc.). Typically two-component kits use pressurized cylinders which are connected by hoses to a dispensing gun. There are advantages and disadvantages to one-component and two-component foams. One of the advantages of the two-component system is its relatively long shelf life resulting from the fact that the chemicals are not mixed until they encounter one-another in the dispensing gun.




One application for a hand-held, portable two-component polyurethane froth foam kit exists in the mining industry. In the event of a fire in a shaft being tunneled, standard procedure is to extinguish the fire by sealing the shaft with a fire “door” and then pumping out from the shaft sealed by the door, the air in the shaft to extinguish the fire. It has been found that polyurethane foam is excellent for sealing the bulkhead or door to the tunnel. As already noted, the polyurethane foam has an adhesive characteristic and the foam can be formulated to provide a relatively quick tack free time with little permeability for gas escape. Surprisingly, the fire door is not adjacent an open flame, and whatever temperature the gases exhausted from the shaft are, they are not sufficiently high in temperature to disintegrate the foam. Because of its long shelf life, a two-component foam is ideal for this application. Standard procedure is to simply provide two-component kits at the shaft being tunneled to seal and secure the fire door or bulkhead to the shaft in the event of a fire.




Different packaging arrangements are used by different manufacturers. Many two-component kit packages use some form of tray with knock-out holes through which the hoses extend after the box is opened and the hoses attached to the cylinder's valved fitting. However, there is at least one two-component polyurethane froth foam box which utilizes cylinders equipped with “dip tubes” which extend through the outlet valve from the inside bottom of the cylinder. This allows the cylinders to be placed upright in the box instead of upside down. This carton does not use a tray and has the hoses extend out the side of the box through knock-out plugs. The carton is carried by a strap affixed to the top cover. The top cover is a flap which has to be opened and closed to gain access to the cylinder's valve after the hoses are connected to the cylinders.




What has been missing from the Prior Art however, is a foam dispensing device which couples both fail-safe operation by a two-stage activation procedure, coupled with a dispensing mechanism whereby the dispensing means is biased into a closed position.




SUMMARY OF INVENTION




The invention is directed to an easily assembled foam dispensing apparatus in which two foam component supply containers are held in place by an carrier assembly which includes a push-button dispensing assembly which is separate from the carrier assembly.




In one principal aspect of the present invention, the entire dispensing apparatus and carrier unit is contained in a carrying case. The carrying case contains two foam component supply canisters and an actuating assembly in the form of two foam component supply tubes, each having a predefined length which is sufficient to permit a dispensing assembly attached to the supply tubes to be operated remotely from the carrying case while interconnected thereto. The material supply tubes, dispensing assembly and one or more detachable dispensing nozzles are positioned within a designated area within the carrying case so that the apparatus may be sold as a single unit or kit. The case not only functions as a carrier assembly for the dispensing apparatus, but may also function as a shipping container therefor or as a display case.




In another principal aspect of the present invention, the dispensing apparatus includes a carrier which holds two foam component supply canisters in place and incorporates an actuating assembly to ensure simultaneous release of the two foam components from their respective supply canisters through foam component supply tubes. The tubes extend to a foam dispenser which includes a dispensing nozzle. The carrier is capable of holding the supply canisters in place in either an upright or inverted orientation depending on whether the canisters have a dip tube contained therein.




Accordingly, it is an object of the present invention to provide an improved foam dispensing apparatus having a foam dispensing member interconnected to two foam component supply canisters by a pair of supply tubes, the supply tubes conveying foam components to the foam dispensing member and permitting the dispensing nozzle member to operate detached from the apparatus and operated remotely from the foam supply canisters adjacent a work area.




It is another object of the present invention to provide a simple foam dispensing apparatus which can be easily operated by an ordinary consumer in which the apparatus includes a carrier member containing two upright foam component supply containers the carrier member including an actuating assembly having means for aligning a pair of material supply tubes with the foam component supply containers and actuating the same to convey foam components from the supply container to a push-button dispensing member biased in the closed position which upon activation through depression, dispenses the fluid contained within the canisters.




These and other objects of the present invention will become more readily apparent from a reading of the following detailed description taken in conjunction with the accompanying drawings wherein like reference numerals indicate the parts and appended claims.

DETAILED DESCRIPTION




Referring now to the drawings wherein the showings are for purposes of illustrating the preferred embodiment of the invention only and not for purposes of limiting the same, the Figures show a two-component portable polyurethane foam apparatus, optionally for inclusion in kit form. It is to be understood that the words “container” or “box” or case or kit are, for purposes of this description, identical and are used interchangeably throughout the specification in describing the combination of the two-component polyurethane foam dispensing system plus carrying case.




The portable two-component polyurethane foam kit includes two cylinders, typically an “A” cylinder, which contains a polymeric isocyanate and a “B” cylinder, which contains a polyol amine or resin. Formulations within each cylinder can vary significantly depending on the application. For example, adhesive applications produce a polyurethane foam which has very little, if any, “foam” while insulation applications use a formulation which produces a significant rise in the foam. Usually, portable, hand carried two-component polyurethane foam kits dispense the chemicals from the dispensing apparatus as a “froth” having a consistency or texture similar to that dispensed from an aerosol can of shaving cream. All such variations in the formulations of polyurethane and whether the chemicals are dispensed as a spray or froth are included within the scope of the present invention so long as the formulations are supplied in a portable, hand-carry form.

While the dispensing holder assembly


10


is preferably used to dispense polyurethane foams, any pressurized fluid (gas, liquid, semi-solid or combinations thereof) is capable of being dispensed. Additionally, the invention is not limited to any one foam or polymer and additionally, is not limited to two canister two-component A and B systems. When the foam to be dispensed is a one-component system, the dispensing apparatus will operate with two canisters, each containing the same or different one-component compositions, and each canister positioned in the locations identified for the A and B components previously. In an alternative embodiment, the assembly will function with only one canister, said canister positioned in either of the two locations indicated previously, or positioned more centrally between those locations.




This invention has been described in detail with reference to specific embodiments thereof, including the respective best modes for carrying out each embodiment. It shall be understood that these illustrations are by way of example and not by way of limitation.
