Description

TECHNICAL FIELD

The present invention relates generally to fluid reservoirs and, more particularly, to a personal hydration system including a fluid reservoir.

BACKGROUND

Personal hydration systems have been used to provide fluids to persons engaging physical activities such as hiking, cycling, running, and various other activities. Conventional personal hydration systems include a reservoir, typically a flexible bladder, for containing a fluid to be consumed by the user, and a drinking tube communicating with the reservoir whereby the user can receive fluids stored in the reservoir. Personal hydration systems may be carried in a pack that can be worn on the back or waist of a user. Because the reservoir is flexible, it is often difficult to carry and/or hold the reservoir while filling the reservoir with fluid. Another drawback of conventional personal hydration systems is that the drinking tube often interferes with the insertion or removal of the reservoir from its pack. The drinking tube may also become entangled or caught on other objects during use.

A need therefore exists for an improved personal hydration system that overcomes these and various other drawbacks of conventional personal hydration systems.

SUMMARY

The present invention overcomes the foregoing and other shortcomings and drawbacks of personal hydration systems heretofore known. While the invention will be described in connection with certain embodiments, it will be understood that the invention is not limited to these embodiments. On the contrary, the invention includes all alternatives, modifications and equivalents as may be included within the spirit and scope of the present invention.

According to one aspect of the present invention, a personal hydration system includes a fluid reservoir having first and second spaced apart apertures. A first port is coupled to the first aperture, and a second port is coupled to the second aperture. A flexible tube has a first end that is coupled to the second port for communication with an interior of the fluid reservoir. The personal hydration system further includes a handle having a first end coupled to the first port, and a second end coupled to the second port. A channel near the second end of the handle extends over at least a portion of the first end of the tube and thereby captures the first end of the tube between the channel and the fluid reservoir.

In another aspect of the present invention, the second end of the handle is selectively removably coupled to the second port. In yet another aspect of the present invention, a groove on the handle, generally between the channel and the first end of the handle, guides at least a portion of the tube as it extends from the channel.

The above and other objects and advantages of the present invention shall be made apparent from the accompanying drawings and the description thereof.

DETAILED DESCRIPTION

FIGS. 1, 1A, 3A, and 3B depict a personal hydration system 10 according to one embodiment of the present invention. The personal hydration system 10 includes a fluid reservoir 12 (shown empty) for receiving fluids for storage and consumption by a user of the personal hydration system 10. In the embodiments shown, the fluid reservoir 12 comprises a flexible bladder having first and second spaced apart apertures 14, 16 formed though a wall of the flexible bladder, with respective first and second ports 18, 20 coupled thereto. The first port 18 defines a relatively wide spout that fluidly communicates with an interior cavity defined by the flexible bladder and facilitates filling the fluid reservoir 12 with a liquid. The first port 18 includes screw threads 22 for securing a closure 24 over the first port 18 for sealing the filled fluid reservoir 12. In the embodiment shown, the closure 24 includes screw threads 26 that are complementary to the screw threads 22 on the first port 18, and the closure 24 may be coupled to the reservoir 12, adjacent the first port 18, by a tether 28. A first end 30 of the tether 28 is secured by a fastener 32 to the closure 24, and a second end 34 of the tether 28 includes a ring 36 that can be removably received around the first port 18 so that the closure 24 is retained by the tether 28 when the closure 24 is removed from the first port 18 for filling the fluid reservoir 12.

The second aperture 16 and second port 20 are spaced a distance apart from the first aperture 14 and first port 18. In the embodiment shown, the second port 20 includes a first end 40 that defines a tube fitting and a second end 42 that is coupled to the second aperture 16 of the fluid reservoir 12, as depicted in FIGS. 3B and 4A-4C. The first and second ports 18, 20 may be operatively coupled to the first and second apertures 14, 16 of the fluid reservoir 12 by heat sealing, radio frequency welding, adhesives, or various other methods suitable to provide a watertight seal between the first and second ports 18, 20 and the first and second apertures 14, 16, respectively. The first and second ports 18, 20 may be provided with wide flange portions 44, 46 to provide reinforcement and/or strain relief to the interface between the first and second ports 18, 20 and the fluid reservoir 12.

The personal hydration system 10 further includes a flexible tube 50 having a first end 52 operatively coupled to the tube fitting of the second port 20 for communication with an interior of the fluid reservoir 12 through the second aperture 16. A second end 54 of the tube 50 is provided with a mouthpiece 56 for use by the user to receive liquid from the fluid reservoir 12 through the tube 50. In the exemplary embodiment shown, the mouthpiece 56 is a bite-actuated mouthpiece that can be actuated from a closed configuration to an open configuration when a user bites upon the mouthpiece 56, or otherwise compresses the mouthpiece 56 with the user's lips or teeth. A magnetic coupling 58 may be provided to facilitate securing the mouthpiece 56 to a portion of a pack (not shown). While a bite-actuated mouthpiece is shown and described herein, it will be appreciated that the mouthpiece may alternatively be a manually-actuated mouthpiece, or may comprise various other configurations suitable to facilitate receiving liquid from the fluid reservoir 12 through the tube 50.

With continued reference to FIGS. 1, 1A, 3A, and 3B, and referring to FIG. 2, the personal hydration system 10 further includes a handle 60 to facilitate carrying and/or holding the reservoir 12, such as when the reservoir 12 is being filled with liquid through the first port 18, or when the reservoir 12 is being inserted into or removed from a pack. In the embodiment shown, the handle 60 extends generally between the first and second ports 18, 20 and has a first end 62 coupled to the first port 18 and a second end 64 coupled to the second port 20. A channel 66 is defined on the handle 60, proximate the second end 64 of the handle 60, and extends over at least a portion of the first end 52 of the tube 50 to define a passageway between the handle 60 and the fluid reservoir 12 through which the tube 50 may extend in a direction generally toward the second port 20. The channel 66 thereby captures the first end 52 of the tube 50 between the handle 60 and the fluid reservoir 12 and provides reinforcement and strain relief to the tube 50, generally proximate the first end 52 of the tube 50.

In the embodiment shown, the second end 64 of the handle 60 is configured to be removably coupled to the second port 20, as shown in FIGS. 4A-4C, to facilitate removing and/or replacing the tube 50 for cleaning or other purposes. The flexibility of the bladder that forms the reservoir 12 facilitates removal of the handle 60, which may be relatively more rigid, by permitting the second port 20 to be moved generally in the direction of the first port 18. In this embodiment, the second port 20 is sized and shaped to be received within a receptacle 70 on the second end 64 of the handle 60. A central alignment tab 72 projecting from the second port 20 aligns with and is received in a central slot 74 defined on the receptacle 70, and side tabs 76a, 76b projecting from the second port 20 are received in corresponding side slots 78a, 78b on the receptacle 70. As the second port 20 is moved within the receptacle 70, resilient fingers 80a, 80b positioned along the lateral sides of the receptacle 70 are pushed outwardly by the side tabs 76a, 76b on the second port 20 (FIG. 4B) and then spring back to secure the second port 20 within the receptacle 70 in a snap-fit manner (FIG. 4C). One or more generally arcuately-shaped rims 82 extending peripherally around the second port 20 engage complementarily shaped rims 84 on the receptacle 70 to facilitate alignment of the second port 20 within the receptacle 70 and to retain the second port 20 within the receptacle 70 of the second end 64 of the handle 60 with the fingers 80a, 80b snap-fit over the side tabs 76a, 76b of the second port 20. As shown in FIGS. 1 and 1A, a window 86 may be provided at the second end 64 of the handle 60. When the second end 64 of the handle 60 is coupled to the second port 20, the second port 20 may be viewed through window 86 to ensure that the handle 60 is properly coupled to the second port 20.

Referring again to FIGS. 1, 1A, and 3A, the first end 62 of the handle 60 may include a support ring 90 that generally circumscribes the first port 18. In the embodiment shown, the first port 18 is formed from a polymeric material that is molded over the support ring 90 at the first end 62 of the handle 60, as depicted in FIG. 3A. One or more apertures 92, 94 may be formed through the support ring 90. In the exemplary embodiment shown, the tether 28 connecting the closure 24 to the first port 18 extends through a first aperture 92 in the support ring 90. Apertures 94 may also be provided on opposite sides of the first port 18 to facilitate routing and securing the tube 50 along a particular side of the fluid reservoir 12, such as with a strap or tie, as may be desired by a user of the personal hydration system 10.

The handle 60 may further include a generally concave groove 98 that extends between the channel 66 and the first end 62 of the handle 60. The groove 98 may be shaped to help guide and align the tube 50 with the handle 60 as the tube 50 extends from the channel 66. If desired, a user may route the tube 50 along one side of the first port 18 and secure a portion of the tube 50 adjacent the first port 18 with a strap or tie extending through one of the apertures 94 provided on the sides of the first port 18. This type of arrangement may help to retain the second end 54 of the tube 50, with the mouthpiece 56, along a desired side of the fluid reservoir 12 for convenient access by a user.

In use, the first end 52 of the tube 50 is connected to the fitting at the first end 40 of the second port 20. The handle 60 is coupled to the second port 20, as described above, such that the channel 66 extends over at least a portion of the tube 50 and provides reinforcement to the first end 52 of the tube 50 where it is coupled to the second port 20. The handle 60 can then be used to facilitate filling the fluid reservoir 12 and placing the fluid reservoir 12 into a carrying pack.
