Description:
IN-CAR HYDRATION SYSTEMS FIELD OF THE INVENTION [001] The present invention is directed to an in-car hydration system. In particular, the present invention is directed to systems for storing a beverage, such as an isotonic sports drink, in a vehicle, keeping it cool, and permitting easy and quick access to the drink by the driver of the vehicle. More specifically, the system is for use in a race car or truck for use by the driver during the race.

BACKGROUND OF THE INVENTION [002] Hydration of a race car driver is extremely important. During a race, a race car driver wears a protective suit and helmet. There is no air conditioning in a race car. Further, many races are run in summer and/or in the Southern U. S. A. As a result, the race car driver experiences a large amount of fluid loss during the race. In order for the driver to be able to compete successfully in the race, he or she will need to replenish the fluids lost or suffer a serious case of dehydration, cramps or both. Furthermore, to receive the maximum hydration benefit, the driver needs to replace the electrolytes (for example sodium and potassium) lost throughout the race.

[003] Additionally, a race car is traveling at speeds approaching and often exceeding 200 mph. Since the race track is shared by upwards of 30 cars, it is important that the driver keep his hands on the steering wheel and stick shift and his feet on the gas pedal, clutch and brake and that there be a minimal use of his hands or feet for other activities, such as drinking fluids.

[004] Present systems used in race cars, such as in NASCAR races, include water bottles, mounted thermos with flexible tubing used like a straw, or a fluid bag in a pouch with flexible tubing used like a straw, such as a system available from BSR Racing Products. These systems, however, suffer from a number of disadvantages. For example, using a water bottle forces the driver to remove a hand from the controls in order to grasp and drink from the water bottle. Further, such a movement distracts the driver's attention from driving, not only hurting his performance during the race but also threatening his safety and those around him. The other systems provide similar distractions. Because of the distracting nature of these systems, the driver may choose not to drink, resulting in dehydration and poor performance.

[005] In addition, it would be beneficial if the replacement fluid were maintained cold throughout the race. A driver is much more likely to drink more fluid, and stay better hydrated, if the fluid is cold. Additionally, the liquids should be available to the driver any time he or she desires a drink. Because of the inadequate systems in place, more often than not, drivers only drink during caution laps or pit stops.

[006] Furthermore, because the weight of the race car is so strictly regulated and controlled, it is important that the hydration system be as light as possible and not weigh much more than the fluid itself.

[007] There are numerous patents directed to systems, devices and methods for dispensing liquids to humans. Many of these include designs for hands-free operation. Most of these have designs which are specifically directed to a particular application, such as for example, on a bicycle or for running. Very few are directed to use in a car or more specifically are designed to withstand the rigors and demands of auto or truck racing.

[008] The present invention is directed to systems and methods for overcoming these drawbacks and meeting these objections in order to provide a driver of a race vehicle with cool liquids at any time, without compromising his or her driving.

SUMMARY OF THE INVENTION [009] The present invention is directed to systems and methods for delivering liquid to a driver of a race vehicle.

[0010] One embodiment of the present invention is directed to a hydration system having an insulated bag or pouch to be mounted within and preferably on the race vehicle. The insulated bag holds a collapsible bladder or reservoir for holding a liquid. Preferably, at least one cooling item, such as a gel pack, for keeping the liquid cool is located in the insulated pouch and preferably in contact with the collapsible bladder. Tubing is used to couple the collapsible bladder and transfer the liquid to a valve or mouthpiece for the driver to drink from. The fluid is then available to the driver through the valve anytime he desires. The valve can be a bite valve.

[0011] Preferably, a pump is coupled to the tubing for ease of circulation of the fluid in and out of the collapsible bladder and to move the liquid from the bladder, through the tubing and to the valve. When the pump is activated, the liquid within the bladder is able to flow from the bladder, through the tubing to the valve and back to the bladder. After activation, the driver can bite down on the bite valve or mouthpiece, and liquid will squirt into his mouth. As a result, the liquid is available to the driver as desired. In addition, the fluid is recirculated through the bladder which is kept cool by the gel pack or other cooling material or medium. As a result, the liquid is kept cool. When the liquid is kept cool, the driver is much more likely to drink the liquid and drink more of the liquid, resulting in less likelihood of dehydration, better performance, and more rapid recovery after a vigorous race.

[0012] In a further embodiment, the pump can be activated using a button coupled to the tubing. In a further embodiment, the button is located on a covering around the tubing.

[0013] In an alternate embodiment, the pump can be activated using a switch or button which can be mounted in the race vehicle. Preferably, the switch is a rocker switch which lights up when turned on.

[0014] In a further embodiment, the tubing has disconnectors located along the tubing for quick disconnect of the tubing [0015] In a preferred embodiment, the fluid used in the present invention is an isotonic sports drink.

[0016] In a further embodiment, the inside of the insulated bag is made of a tetrafluoroethylene polymer.

[0017] In an alternative embodiment, a gas bladder for holding pressurized gas to apply pressure against the bladder of the liquid is located within the insulated bag or pouch. In this embodiment, a pump is not necessary but could be used if so desired. At least one gel pack for keeping the liquid cool is located either in the insulated pouch, in the reservoir or in both.

Tubing is used to connect the collapsible bladder to a valve near the driver's mouth. The pressurized gas in the gas bladder puts pressure on the collapsible bladder and will force the liquid out of the collapsible bladder through the tubing to the valve when the driver wishes to drink. A bite valve can be used by the driver to activate the system.

[0018] Another embodiment of the present invention is directed to a hydration system to be located within the race vehicle and which includes a shell with inner and outer walls and freezer gel in between. In this embodiment, a bottle of liquid is placed within the shell. The shell has a lid to keep the bottle in the shell. Tubing is coupled to the bottle in the shell and is used to transfer the liquid from the bottle to a valve in close proximity to the driver, preferably near the driver's mouth. The fluid is then available to the driver through the valve anytime he desires. Preferably, the shell is held or mounted onto the race vehicle.

[0019] In one alternative of this embodiment, a modified cap with multiple ports with disconnectors in the cap is placed on the bottle. The bottle is then placed in the shell. The ports mate with ports in the shell allowing circulation of the fluid in and out of the bottle. A pump can be connected to the tubing to move the liquid from the bottle to the valve. When the bottle of liquid with the modified cap is placed in the shell and the pump activated, the liquid within the bottle is able to flow from the bottle, through the cap and tubing to the valve and back to the bottle. As a result, the liquid is available to the driver as desired.

[0020] Methods using these embodiments are also contemplated in this invention.

[0021] The present invention provides a hydration system which requires minimal use of the driver's hands or feet. The present invention also provides a hydration system which allows the driver to drink fluids without taking his or her eyes off the track or road.

[0022] The present invention also provides a system wherein the fluids within the system will be maintained cool for the duration of the race.

[0023] The present invention also provides a system in which little weight beyond the fluid is added to the race vehicle.

[0024] The present invention is not limited to race cars but can also be used, for example, in race trucks.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS [0041] A first embodiment of the present invention is illustrated in Fig. 1. In the system 10 of this embodiment, a flexible or collapsible bladder or reservoir 12 holds fluid, such as for example an isotonic fluid like GATORADES, fortified water, or plain water. The bladder 12 is placed in an insulated pouch or bag 14. In one alternative embodiment, the insulated bag can have an inside and outside shell made of a Kevlar fiber, such as for example one called Gentex, with an aluminized Mylar cover. A logo can be placed on the outside shell or cover. Preferably, about 1 inch of EVA foam insulation is located between the inside and outside Kevlar fiber shell. The aluminized Mylar cover reduces accumulation of radiant or conductive heat. In another alternative, while the outside of the shell is made of the Kevlar fiber with the aluminized Mylar cover, the inside of the shell is made of a glass fiber weave polytetrafluoroethylene (PTFE), such as for example Teflon@ coating. This coating helps keep the contents of the bag cool for a longer period, is waterproof and prevents fungus from forming. Preferably, between the Kevlar fiber coating and the Teflon coating is about 1 inch of EVA foam insulation. In another alternative, instead of having an insulated bag, just the reservoir may be used. For example, the reservoir itself may be insulated. Alternatively, the bag and reservoir may be combined as one item.

[0042] In a preferred embodiment, bladder 12 will hold 100 ounces of fluid.

Alternatively, the bladder can be made to hold 4.25 liters, 3 liters or 2.25 liters. The present invention, however, is not limited to such a size, as different sizings can be provided as desired and/or more or less fluid can be in bladder 12 as needed for the race.

[0043] Examples of bladders or reservoirs which can be used in the present invention include those made by TFO Inc. , MSR, Platypus and Bi-Polar. The bladders can be made of, for example, bi-laminate or tri-laminate material. Additionally, a logo can be placed on the bladder.

Preferably, bladder 12 has two openings 16,18. In a preferred embodiment, a Flexi Flask bladder from TFO Inc. holding 101 ounces of fluid and having two openings is used. The present invention, however, is not limited to the number of openings on the bladder. A dip tube 17 can also be located in one of the openings 18. A dip tube 17 allows the driver to drink almost all of the liquid from the bladder. Without such a tube, it is possible that when drinking, the sides of top portion once emptied could stick together preventing the flow of liquid out of the bladder. Tubing 20 is coupled to the bladder 12 and each opening 16,18 of the bladder. Tubing 20 can be for example FDA 3A Tygon tubing approved for food industry use, beverage grade.

A cap 22, with a connector 24 therein, can be placed on the openings, and the connector 24 connected to the tubing 20. Such caps and connectors typically are available from the manufacturer of the collapsible bladder. A quick disconnector can be used with one or both of the openings for quickly connecting and disconnecting the bladder. Such disconnectors also help reduce line kinking and reduce the total number of components. A standard connect appears to work best with a dip tube. Color coding such connectors or quick disconnectors helps prevent confusion when connecting the bladder.

[0044] At the other end of the tubing is a valve or mouthpiece 25 to deliver the fluid to the driver's mouth. Preferably, a bite valve is used. By biting on the valve, fluid will be delivered into the driver's mouth. Many bite valves are available. One example of a possible bite valve that can be used with the present invention is a Camelbak Big Bite Valve.

[0045] Preferably, a cooling item, medium or material is located within the insulated bag to keep the fluid cool. In one embodiment, one or more freezer gel packs 26 are located within bag 14 and around bladder 12 to keep the fluid cool. An example of a freezer pack that could be used with the present invention is a U-Tek Refrigerant gel pack + 30°F from Polyfoam Packers Corporation. Alternatively, a Midlands Polar Pack or other similar type cooling items, which are well known in the art, can be used. In another alternative, a freezer gel component can be part of bladder 12. Bi-Polar sells a bladder with such a design.

[0046] Preferably, a pump 28 is used with the present invention to move fluid from bladder 12 to the valve 25. One example of such a pump is a positive displacement gear pump, such as for example a Greylor model PQ-12 DC or a Delrin Miniature Gear pump. The pump is run off a power supply, such as a battery pack 29. One example of a battery pack is a 12 volt battery pack. Such a battery pack can be provided by Rendell sales and other similar manufacturers. Other size battery packs can also be used with the present invention. For example, a 7V, 7A battery pack could be used. Such a battery pack could provide a longer life and may eliminate the need for an on-off switch, which is discussed infra. Alternatively, the pump could be connected to the car, and particularly its electrical system, and powered by the car itself. Other pumps that can be used include a diaphragm pump, a vane pump, a piston pump, a centrifugal pump, and a peristaltic pump. Each type of pump can be of a generally know construction. Preferably, insulation is provided around the pump and battery pack so that heat from them will not heat the fluid. The pump and battery pack could also be placed in a separate pouch or compartment (not shown) within bag 14. Use of the pump is advantageous because it quickly and easily moves the fluid from the bladder to the valve to be available for the driver to drink. This eliminates the need for the driver to have to suck on the valve in order to get fluid which requires a lot of effort and energy from the driver. Also as explained infra, the use of the pump helps keep the fluid cool.

[0047] Preferably, at least one piece 30 of tubing is connected between bladder 12 and pump 28. Another piece of tubing 32 is connected between pump 28 and a Y-connector 34 (see Fig. 2). Another piece of tubing 36 is connected between Y-connector 34 and valve 25. For this part of the tubing, a Camelbak Tube Director can be used to provide a partially rigid tubing to ease the driver's use of the device. Alternatively, other partially rigid tubing could be used. Preferably, pump insulation 42 is provided around at least a portion of tubing 36. Yet another piece of tubing 38 is connected between Y-connector 34 and bladder 12. An example of a Y- connector is a 8 mm plastic piece from Cole Palmer. It may be helpful to heat the Y-connector before use so that the two top prongs of the Y can be pushed closer together. This can improve the streamlining of the tubing. Quick disconnectors 40 with shut-offs can also be located on the tubing to disconnect the bladder 12 from the tubing and valve. While optional, the disconnectors make it easier to replace components of the system, such as the bladder, without having to replace the whole system. Again color coding them can reduce confusion when connecting and reconnecting them. Preferably, the tubing 20 is enclosed within insulation 42 such as for example elastomer pipe insulation with thermosleeve. Because of the high temperatures that develop in the car, insulation 42 keeps the liquid cool as it travels through the tubing.

[0048] In order to activate the pump, a button or switch 44 can be connected to pump 28.

For example, wires 45 can be connected between button 44 and pump 28 and coupled along the tubing 20. In a preferred embodiment, wires 45 and tubing 38 are located within insulation 42, and button 44 is located on insulation 42. The driver can then grab the insulated covered tubing with the button thereon and push button 44 to activate the pump. Once the pump is activated, liquid flows out of bladder 12 through tubing 30 to pump 28. The liquid then flows through tubing 32 to Y-connector 34 and then to tubing 36 and tubing 38 and finally back into bladder 12. When the driver bites down on the bite valve, fluid will be delivered into the driver's mouth.

This flow pattern keeps the liquid from sitting in the tubing where it would quickly get warm by exposure for an extended period of time to the heat in the vehicle, without the insulated protection of the bag and gel packs therein. Instead, the (unused) liquid flows back into the bladder where it mixes with the cool liquid therein and stays cool.

[0049] In an alternate embodiment, as shown in Figs. 3 and 4, a switch or button 144 can be located near the driver on the car to operate the pump. Preferably, the switch or button 144 is located where the driver can easily access it, such as with his or her hand or foot. Once the driver hits the button or switch 144, the pump will begin operating and will begin pumping fluid making the fluid available to the driver as described above. This button could be a simple on- off button or switch or a toggle switch. For example, the toggle switch could have three positions, an off position, an on position, and a momentary on position where the driver would hold the switch in this momentary on position only when he wants the pump on.

[0050] In a preferred embodiment, the switch 144 can be connected to a rocker switch 145, as shown in Fig. 5. One potential problem with a traditional switch is that it can be accidentally bumped on. The pump will then begin to operate, and because the noise of the car and the race will drown out the sound of the pump operating, the pump will continue to run until the battery runs out. A rocker switch is advantageous as it is very difficult to accidentally switch or bump on. In this embodiment, the driver pushes the rocker switch 145 on when he wishes the pump to begin operating to make fluid available to the driver. The driver pushes the rocker switch off when he is done. A light can also be provided on the rocker switch. The light will go on whenever the switch is on so that the driver will know when the pump is on and running.

This will help to alleviate the problem of the pump being on and running, without the driver realizing it because of the noise of the car and race, and running until the battery runs out. An example of such a switch is an APEM K6 series switch.

[0051] Preferably, bag 14 has a flap 46 to keep bladder 12 in the bag during the race. In order to keep flap 46 closed, a fastening apparatus is used, such as hook and loop strips 48, such as for example VELCRO@, or a buckle 149 and strap 49, or both. Figs. 6 and 7 show another view of flap 46 and fastening apparatus 48 and 49. An example of such a buckle is a quick lock buckle. Alternatively, a zipper or other fastening apparatus could be used.

[0052] Bag 14 also preferably has straps 50 with hooks 52 which can be used to fasten bag 14 to, for example, a roll bar in the race vehicle. For example, load rated containment straps 51 can be used. In a preferred embodiment, bag 14, with bladder 12, can be mounted or hung from the roll bar of a race vehicle. For example, hooks can be attached to the roll bar, by welding or bolts. The hooks 52 on bag 14 can be attached to the hooks on the roll bar. So as to not obstruct the driver's vision, the bag can be hung securely on the right side of the driver's cockpit.

[0053] Instead of a bite valve, the present invention also contemplates that an arrangement can be provided to allow the driver to access the fluid by sucking or sipping. For example, a tip can be placed on the end of the flexible tubing on which the driver could suck or sip the fluid.

[0054] The liquid in the bladder can be an isotonic beverage, such as for example GATORADEO. However, other size beverage containers and other types of beverages, including water and fortified water, are also within the scope of the present invention.

[0055] In any of the embodiments of the present invention, the tubing and valve can be fed to the driver's mouth in a number of different ways. For example, a hole can be drilled through the driver's helmet. The flexible tubing is inserted through the hole and on the inside of the helmet, attached to the valve as shown in Fig. 3 at 60. Fig. 8 shows an enlarged view of a possible connection through the helmet. In one possible example of this embodiment, as illustrated in Fig. 8, tubing 36 is connected to a solid or partially rigid piece of tubing 62 that is bent at an angle, such as for example the approximate 90° angle shown in the figure. An example of such a tubing is a Camelbak 90° Hydrolock. Tubing 62 is preferably coupled to one or more pieces of dental tubing 64,66. Examples of such dental tubing include Pearson dental tubing no. X26-05-09, X26-05-11, or X26-05-06. A bite valve 25, such as that discussed supra, or Camelbak thermal control pak can be used at the end of the tubing 66. Preferably, the valve should be in close proximity to the driver's mouth but not continuously in the mouth.

Alternatively, the flexible tubing can be inserted through the visor area of the helmet or under the helmet and up by the chin. In any case, the valve would be placed in close proximity to the driver's mouth.

[0056] In order to keep the flexible tubing from getting in the driver's way, in another embodiment, the tubing or insulation covering it can be attached to the driver's suit or to the restraint structures within the vehicle. Preferably, the tubing would be attached with a hook and loop material, such as VELCRO@, and/or other quick disconnect devices, so that the driver can become quickly disconnected from the tubing if it is necessary for him to quickly leave the car.

Such attachment material also makes it easy for the driver to locate and re-attach the tubing when he wishes to take a drink and to replace the tubing after drinking.

[0057] Fig. 9 is a cross sectional view of an alternative embodiment of the system of this embodiment. In this system, reservoir 100 includes a flexible or collapsible bladder 104, such as described supra, which holds the fluid inside. Freezer gel packs 106 or other cooling items are located within reservoir 100 and around bladder 104 to keep the fluid cool. Preferably, a gas bladder 108 is also provided within the reservoir 100. Gas bladder 108 keeps bladder 104 under pressure so that when the driver bites down on the bite valve, fluid will be delivered into the driver's mouth. Preferably, gas bladder 108 is filled with C02 or other inert gas. Typically, it is coupled to a canister containing the gas (not shown). Preferably, gas bladder 108 is under 7 psi of pressure. The outside of the reservoir is a fabric bag 110.

[0058] As shown in Fig. 9, reservoir 100 is placed in insulated bag or pouch 102.

Insulated pouch 102 preferably includes about 1 inch of EVA foam insulation 112 and a shell 114. Shell 114 can be made of foil so as to reduce accumulation of radiant or conductive heat.

An example of such a foil is a reflective mylar coated glass strand weave material.

Alternatively, freezer gel packs can be included within insulated pouch 102, instead of within reservoir 100. In another alternative, a freezer gel component can be part of fluid bladder 104.

Bi-Polar sells a bladder with such a design.

[0059] Fig. 10 shows a top view of an example of pouch 102. Fig. 9 is taken along line A-A of Fig. 10. Reservoir 100 fits within pouch 102. Preferably, pouch 102 has a flap 116 to keep reservoir 100 in the pouch during the race. In order to keep flap 116 closed, a fastening apparatus is used, such as hook and loop strips 118, such as for example VELCRO@, or a buckle and strap (not shown in this figure), or both. Alternatively, a zipper or other fastening apparatus could be used.

[00 60] Figs. 11 and 12 illustrate straps 120 which can be used to fasten pouch 102 to, for example, a roll bar in the race vehicle. In a preferred embodiment, pouch 102, with reservoir 100, can be mounted or hung from the roll bar of a race vehicle. So as to not obstruct the driver's vision, the pouch can be hung securely on the right side of the driver's cockpit.

Preferably, flexible tubing, such as that described in the first embodiment, is connected to the reservoir through the pouch. At the other end of the tube is a bite valve, such as that described above. By biting on the valve, fluid will be delivered into the driver's mouth.

[0061] Another embodiment of the present invention is illustrated in Fig. 13. This embodiment is intended to hold a bottle 210 of a fluid within an enclosed shell 212. Preferably, the shell 212 has an inner wall 214 and an outer wall 216. These walls 214 and 216 can be made of carbon fiber, aluminum or similar type materials. Carbon fiber is presently preferred as it is lighter than aluminum. Preferably, walls 214 and 216 are approximately. 050 inches thick.

Walls 214,216 create an inner evacuated space 218 between the walls. In a preferred embodiment, the inner evacuated space is 1/4 inch wide. A freezer gel 220, such as for example Polyfoam UTEK + 30°F freezer gel, can be placed in this inner evacuated space 218. When frozen, gel 220 will keep the fluid within bottle 210 cold during the race. In a further embodiment, a layer of insulation 222 is placed around outer wall 216. Layer 222 can be made of for example Ethylene Vinyl Acetate (EVA) foam which is a close cell foam with high tear strength. Another possible insulation is a vacuum insulation produced by Nanogel. Other similar substances could also be used. Preferably, layer 222 is between */4 inch- inch thick.

Layer 222 will help keep the liquid cold during the race. Preferably, the liquid will be maintained at a refrigerator temperature throughout the race.

[0062] In order to keep bottle 210 within shell 212, shell 212 has a lid 224. In a preferred embodiment, lid 224 has a pivot point hinge 226. The lid 224 pivots open on hinge 226 to provide complete and easy access for putting a new bottle in shell 212 and for removing a used bottle. A latching or locking mechanism 228 can be located on shell 212 to lock the lid and bottle in place. In one embodiment, latching mechanism 228 can include a D-ring 230 which hooks on a hook 232 on lid 224. Latching mechanism 228 can also include a handle 234.

Handle 234 can be used to hook ring 230 on hook 232 and then clamp and lock lid 224 on shell 212 by pressing handle 234 against the shell. The lid, latch mechanism and hinge can be made of aluminum, carbon fiber or similar material. Fig. 14 shows a top view of lid 224 and latching mechanism 228.

[0063] Preferably, shell 212 is designed to hold a 64 ounce bottle of an isotonic beverage, such as for example GATORADE@. However, other size beverage containers and other types of beverages, including water, are also within the scope of this embodiment. In addition, while the preferred embodiment holds a plastic bottle, the present invention is not limited to use of plastic bottles.

[0064] In a further embodiment, a spring 223 is located at the bottom of shell 212.

Spring 223 allows bottle 210 to be spring loaded in shell 212. As a result, when lid 224 is opened, bottle 210 will spring out for easy removal of the bottle.

[0065] The system of this embodiment is contemplated both for use with a single bottle of fluid for the entire race or replacement of the bottle with another bottle during the race. For example, if it is desired to change the bottle at a pit stop, the driver or crew member merely has to open the lid, and the bottle will pop up. He or she can discard that bottle, pop another bottle into the shell, close the lid and quickly be out of the pit stop.

[0066] In Fig. 13, bottle 210 has a standard cap 236 such as that found on a bottle bought from a store. At the bottom of shell 210 is a sharp-tipped apparatus 238 to puncture cap 236.

Apparatus 227 can be made of plastic, metal or similar material and is connected to flexible tubing 240. Tubing 240 can be for example FDA 3A Tygon tubing as discussed supra. Tubing 240 should be long enough to reach from shell 210 to the driver's mouth. At the end of the tubing, opposite apparatus 236, is a valve. A swagelok fitting 237 preferably connects tip apparatus 238 and tubing 240.

[0067] Accordingly, when bottle 210 is placed in shell 212, apparatus 238 punctures cap 236. Fluid then flows into tubing 240. Tubing 240 is connected to a valve near the driver's mouth. The fluid is available to the driver by sucking or sipping on the valve. Alternatively, as described below, a pump may be used to circulate the fluid.

[0068] In an alternative embodiment, a modified cap 242 can be screwed on bottle 210 to replace the original cap on the bottle. Preferably, cap 242 is made out of polypropylene. It has dual ports 243 with single shut off quick disconnect connectors imbedded in the body of the cap. Cap 242 mates with two nipple-like ports inside shell 212 such that when the system is engaged, fluid is allowed to bypass the shut-offs and circulate in and out of the bottle. This is done so that the fluid will stay cool throughout the race and will not warm up sitting in the tubing. Fig. 15 shows an example of the top of such a cap. Cap 242 is coupled to tubing 240 and to a valve near the driver's mouth. As discussed supra, quick disconnectors can also be located on the tubing to disconnect the shell system from the tubing and valve, and a bite valve can be used.

[0069] Preferably, a pump, such as those discussed supra, is used to move fluid from shell 212 to the valve. As also discussed supra, a button or switch can be used to operate the pump. Once the driver hits the button or switch, the pump will begin operating and will begin pumping fluid making the fluid available to the driver. The pump also recirculates the fluid back through the bottle in the shell to keep it cool.

[0070] Preferably, shell 212 with lid 224 are intended to be placed in a bracket 250 within the race vehicle. For example, this bracket could be placed on the floor of the driver's cockpit, preferably on the right side of the driver's cockpit so as to be out of his way, and riveted or welded to the floor. Figs. 16a, 16b, 16c show an example of bracket 250 which could be used to hold shell 212 in a race vehicle. The radius of bracket 250 will be determined by the size of shell 212. The size of shell 212 is dependent upon the size of the bottle which is to be placed in the shell.

[0071] Shell 212 can be held in bracket 250 by various fastening apparatus. For example, zip ties, cable ties or similar devices can be placed on shell 212 and attached to each side of bracket 250 to hold shell 212 on the bracket. Alternatively, as shown in Fig. 16b, bracket 250 could have a top half 252 which is connected by a hinge 254 to one side of bracket 250.

The top half 252 of the bracket would fold over shell 212 within bracket 250 and be fastened to the side of bracket 250 opposite of the hinge.

[0072] It will be understood that the embodiments and examples of the present invention, which have been described, are illustrative of some of the applications of the principles of the present invention. Numerous modifications may be made by those skilled in the art without departing from the true spirit and scope of the invention.
