Description

RELATED APPLICATIONS

This application claims priority to U.S. provisional application Ser. No. 60/620,780 filed Oct. 21, 2004.

BACKGROUND

1. Field of the Invention
The present invention relates to a hydration system. One embodiment of the present invention relates to a universal hydration system for drinking fluid from an independent container.
2. Background
The human body is composed of over 90% water and a human being is said to only be able to survive for three days without liquid. Therefore, the consumption of fluids is extremely important during all activities. The consumption of fluid is especially necessary during athletic activities.
Traditionally, people transport fluids in sealable containers for consumption during activities away from home. These sealable containers include thermoses, canteens, flasks, polycarbonate bottles, etc. However, recently companies such as Camelbak, Platypus, etc have introduced hands free bladder type hydration systems that allow individuals to consume fluids without opening a sealable container and interrupting their activities. All of these systems generally include a bladder, a tube and some form of bite valve. The bladder is a flexible container configured to hold the fluid. The tube is generally coupled to the outside of the bladder and is positioned at the bottom of the bladder to allow for access to all of the fluid. The tube does not extend into the bladder in any of these hydration systems. The other end of the tube is coupled to a bite valve that allows a user to open the valve using some form of hands free mouth movement. Once the bite valve is opened, a user is able to suck out fluid. These hands free bladder systems have significant advantages over existing sealable fluid transportation systems.
Unfortunately, existing hands free bladder systems also have significant problems. One problem is the inherent weakness present in almost all existing bladders. Bladders are generally flexible containers composed of some form of rubber or plastic. These containers are very vulnerable to punctures and leaks. For example, if an individual falls while mountain biking, the impact of the fall may cause the bladder to leak. In addition, the retail price of bladders is too expensive to make them disposable to low income individuals. Many users avoid putting sports drinks in bladders because of the inherent bacteria problems that occur from dormant sports drinks. Likewise, it is very difficult to clean a bladder because of their shape and dimensions.
Therefore, there is a need in the industry for a hydration system that maintains the hands free capability of existing systems but minimizes or avoids the many problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to a hydration system. One embodiment of the present invention relates to a universal hydration system for drinking fluid from an independent container. The universal hydration system includes a tube and a cap configured to couple with an independent container. The tube extends through the cap in a leak resistant manner and is disposed within the interior of the independent container. The other end of the tube may be coupled to a tube cap of some sort including a bite valve or a cover, or may be left exposed. The cap is coupled to the independent container using the independent container's coupling system. Additional caps configured for coupling to various containers may also be included with the system. In addition, the additional caps may be stored on the tube so as to create a one piece universal hydration system. Likewise, the full length of the tube can be extended into the container for storage purposes. Additional embodiments may also include the ability to pressurize the independent container via some form of pump and valve system. While embodiments of the present invention are directed towards a universal hydration system, the teachings of the present invention are also applicable to other areas. For example, the teachings of the present invention may be applied to a universal fluid dispensing system.
Reference is initially made to FIG. 1, which illustrates a component view of a universal hydration system in accordance with one embodiment of the present invention. The universal hydration system is designated generally at 100. The universal hydration system 100 generally includes a tube 110 and at least one bottle cap 120. The universal hydration system 100 can be configured for use with any one of a plurality of existing bottles 140. The bottles are independent of the hydration system in that they originated from an independent sale. For example, a Gatorade® bottle may have originally been sold containing Gatorade® fluid. The bottle may be reused/recycled as an independent container for use with the universal hydration system. The universal hydration system 100 may also optionally include one or more tube ends 130. The tube 110 further includes a body 104, a bottle end 106, and a user end 102. The tube 110 is flexible and may be composed of any material including but not limited to polyethylene, Tygon, PVC, urethane, elastomer, rubber, vinyl, etc. The diameter of the tube 110 should be sufficiently large to provide adequate fluid transportation.
The universal hydration system 100 may include one or more bottle caps 120 to provide flexibility upon which types of bottles it can operate with. Each bottle cap 120 is sized for a particular bottle 140. For example, two liter soda bottles require a very small cap similar to cap 122. Likewise, sports drink bottles generally have a medium sized opening and may conform to the cap 124. Any type of cap may be used and remain consistent with the present invention. Each of the bottle caps 120 include a hole or recess through which the tube 110 is configured to extend. The hole is generally sized smaller than the diameter of the tube to facilitate a substantially leak proof seal. This seal will be discussed in more detail with reference to FIG. 3. Alternatively, a multi-cap could be utilized which accommodates a variety bottle sizes. A multi-sided and single-sided multi-cap are illustrated and described in more detail with reference to FIGS. 4A and 4B respectively.
The universal hydration system optionally includes one or more tube ends 130. A tube end 130 is a device positioned on the user end 102 of the tube in order to provide a particular function. One common function of a tube end 130 is to prevent leakage of fluid when the hydration system is not in use. For example, a bite valve 134 seals the user end 102 of the tube 110 until a user applies a biting force causing it to open. Likewise, a cap end 130 allows the user end 102 of the tube 110 to be capped when not in use. Various other tube ends 130 may be used and remain consistent with the present invention. For example, a manual valve may be added to some portion of the tube 110 to allow a user to block the flow of liquid through the tube.
The universal hydration system also requires the use of an existing bottle 140. The existing bottle 140 is generally recycled from another use but may be sold as part of the universal hydration system. A two liter soda bottle 144 is generally composed of a smooth yet durable plastic material. Likewise, a sports drink bottle 142 is composed of a durable plastic material. The concept behind the universal hydration system is to allow it to be used with any fluid bottle. The use of an existing bottle rather than a bladder with traditional types of tube oriented hydration systems saves money and promotes recycling.
Reference is next made to FIG. 2, which illustrates an assembled view of one embodiment of the present invention configured for hydration use. The tube body 104 extends all the way to the bottom of the bottle 200 in order to allow a user to access all of the fluid 210 within the container 200. This embodiment includes two caps 122, 124. Cap 122 is disposed in a storage configuration while cap 124 is disposed in an operational configuration. Additional storage caps may also be stored on the tube wither in or out of the container. The tube body 104 extends through the cap 124 in a sealed manner to prevent leakage of fluid 210. The user end 102 of the tube 110 is covered with a bite valve type tube cap to prevent leakage of fluid 210. Various suspension systems and backpacks may be utilized in conjunction with this system to facilitate hands free hydration.
Reference is next made to FIG. 3, which illustrates a cross-sectional view of a tube extending through a cap in accordance with the present invention. The cap 124 includes a plurality of threads used for coupling to an existing bottle. The cap 124 also includes a hole sized slightly smaller than the diameter of the tube body 104 in order to facilitate a seal between the tube body 104 and the cap 124. Since the tube is flexible it can be pushed through the cap in a compressed configuration. The resiliency of the tube will cause it to expand into the hole in the cap 124 forming the seal therebetween. In addition, a one way valve may be included in the hole that would allow air into the container but prevent fluid from exiting the container. A pressure vacuum may result from sucking fluid out of the container and a one-way valve/air breather vent would prevent the vacuum from inhibiting the flow of liquid out the tube.
Reference is next made to FIGS. 4A and 4B which illustrate cutaway profile views of multi-sided and single-sided multi-caps respectively. Multi-caps allow a single cap to accommodate a variety of container opening shapes. FIG. 4A illustrates a cap in which multiple receiving recesses are disposed on both the top and bottom of the cap. In order to utilize both sides of the cap, the cap may need to be removed and reinserted such that the receiving recesses are facing towards to container. Alternatively, the tube could be reversed such that the fluid end becomes the user end and vice versa. Any additional end caps would need to be removed and coupled on the alternative tube end. FIG. 4B illustrates a cap in which multiple receiving recesses are disposed on a single side of the cap. Multi-caps may be especially useful for efficient manufacturing in that a single cap could be manufactured which accommodates a wide variety of containers.
Reference is next made to FIG. 5, which illustrates an alternative hydration system embodiment including a pressurization system, designated generally at 500. The illustrated hydration system 500 includes a bite valve 505, a tube 510, a pump 515, a cap 520, and a container 530. The illustrated pump 515 is a bulb pump which can be squeezed causing an evacuation of air. The pump 515 also includes a check valve 517 which allow air into the pump as it resumes its original shape. The check valve 517 also seals the air within the pump 515 such that the evacuated air can be directed into the tube 510. The container 530 further includes an air region 535 and a fluid region 540. As air is pumped into the container 530 via the pump 515, it will act to increase the pressure within the air region 535 causing a force to be applied on the fluid. This force will assist in fluid transportation up through the tube during operation of the hydration system.
A pressurization system includes an air intake mechanism and some form of valve to maintain pressure. The illustrated pressurization system is the bulb pump 515 attached to the tube 510. The valve is the check valve 517 disposed on the bulb pump 515, which allows air into the bulb but not out of the bulb. The bulb can then be repeatably compressed to insert air into the container 530 thereby pressurizing the container 530. The check valve 517 on the bulb pump 515, the seal between the cap 520 and the container 530, and the seal between the tube 510 and the cap 520 all operate to maintain the pressure within the container. Numerous alternative pressurization systems are contemplated and are consistent with the present invention. For example, the tube 510 may include multiple independent chambers in which one chamber is dedicated to pressurization while another is utilized for fluid transportation. Likewise, the caps may include one or more auxiliary recesses for use in attaching pressurization tools such as a pump and/or a check valve. A further embodiment of a pressurization system includes a check valve and relies on the compliance properties of the container to act as a pump in response to a compression force.
Reference is next made to FIG. 6, which illustrates a hydration system embodiment of the present invention in which the tube is disposed within the container for efficient storage, designated generally at 600. The illustrated hydration system 600 includes a bite valve 605, cap 620, tube 610, and container 630. The container further includes an air region 635 and a fluid region 640. As illustrated, the tube body 610 may be extended entirely within the container 630 for the purpose of storage and efficient transportation. During operation, the tube body 610 may be extended out from the container 630 to accommodate a desired length or function.
Thus, as discussed herein, the present invention relates to a hydration system. One embodiment of the present invention relates to a universal hydration system for drinking fluid from an independent container. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
