DETAILED DESCRIPTION OF THE INVENTION

[0033] A Mouthguard with Hydration System is disclosed herein in conjunction with the accompanying figures.

[0034] The Mouthguard with Hydration System is comprised of a mouthguard protective component having an integral valve operated by the tongue, a pressurized fluid reservoir, and a flexible tube portion for providing fluid communication between the protective component and the fluid reservoir. In the illustrated embodiments of the present invention described herein, the fluid reservoir takes the form of a fluid container (deformable or rigid) or a fluid bag. Fluids stored in the reservoir may include, but are not limited to, water and sports drinks containing electrolytes.

[0035] The mouthguard protective component is preferentially fabricated from medical grade silicone rubber with a hardness appropriate for the application. It is shaped to fit between the teeth and can be of several sizes to accommodate users of different ages. It includes a spring component that keeps the valve closed until it is pressed upon by the tongue.

[0036] Throughout this specification, like reference numbers signify the same elements throughout the description of the figures.

[0037] According to a first embodiment of the invention, as shown in FIGS. 1A, 1B, 2A and 2B, a mouthguard protective component 10 comprised of a rubber component 11 having a groove 12 to accept the top teeth, a flat portion 13 against which the bottom teeth rest, and a front plate 14 which protects the front teeth against injury. Mouthguard protective component includes an arc shaped spring 18 that keeps a valve 20 closed. A fluid handling component is comprised of a hollow tubular portion 15 that accepts a connector or fitting 16 that enables connection to a delivery tube 39 (See FIG. 6). Rubber component 11, groove 12, and front plate 14 collectively form a mouthpiece element.

[0038] The internal fluid handling passage are shown in FIGS. 3A and 3B. The tubular portion 15 shown in the front view of FIG. 3A has a central hole 17 that enables fluid to pass from the exterior of the mouthguard to the interior. This is shown from the back or inside view as shown in FIG. 3B.

[0039] Valve 20 is shown in FIG. 4B. Valve 20 has a generally hemispherical occluder component 21 (domed portion), an elongated shaft component 22, and a dome shaped retaining element 23 so that it remains affixed to the spring 18 (best shown in FIG. 1A).

[0040] Referring to FIGS. 1A and 1B, mouthguard protective component 10 of the illustrated embodiment has a shape that is able to fit comfortably in the user's mouth. The flexible walls 12, 13, and 14 hold or cradle the teeth in a position that then allows the user to push on the spring 18 with their tongue, releasing the flow of water which is then swallowed. Mouthguard protective component 10 is preferably molded from a soft, compliant substance such as medical grade silicone rubber. Connector 16 and valve 20 (see FIGS. 4A-4C) are created from a hard plastic, or other rigid materials, via injection molding or similar process.

[0041] The ribbed connector 16 is sized to fit into the tubular portion 15 which is at the front of mouthguard protective component 10. The opposite end of the connector 16 fits into the delivery tube 39 which delivers pressurized fluid from deformable storage container 36 (see FIG. 6) or a rigid storage container 30 (see FIG. 7). Watertight connections are assured by proper sizing of the two ends of the ribbed connector 16 within the tubular portion 15 of mouthguard protective component 10, and within the delivery tube 39.

[0042] Referring to FIGS. 4B and 4C, the domed portion 21 of the plunger valve 20 creates a large enough seal with hole 17 formed in the body of mouthguard protective component 10, so that it can hold back the pressure of the supplied fluid and prevents any undesired leaks of fluid into the mouth, until the spring 18 is depressed.

[0043] The valve 20 is kept closed by firm contact between the domed portion 21 and the rim of the hole 17 by the force of the pressurized fluid applied on the back face of the domed portion 21, as well as by the elastic preload bias of the arc-shaped spring 18. The resting state of the system is such that spring 18 is preloaded slightly to pull the domed portion 21 against the rim of hole 17, thus maintaining a fluid seal. Pressure applied by the user's tongue in a forward direction against the spring 18 is required to unseat the rounded portion 21 from the rim of the hole 17, and thus, enable pressurized fluid to pass around the valve 20 into the mouth of the user.

[0044] Mouthguard protective component 10 according to the present invention is both hands-free, as no action by the user's hands is required to enable the release of the fluid, as well as free-standing, in that no action by the user is required to prevent water from passing into the user's mouth. This is in stark contrast to the invention of Kennedy (U.S. Pat. No. 9,687,722) which requires the user to continually clench teeth against a valve in order to prevent water from passing into the user's mouth. In the present invention, water cannot enter the user's mouth unless the user's tongue is pressed against spring 18 with sufficient force to overcome the force on the closed valve and open it. This is inherently a safe system.

[0045] Pressurized fluid is passed through delivery tube 39 to valve 20 via the ribbed connector 16 that connects to tubular portion 15.

[0046] Additional measures can be used to secure the ribbed connector 16 within the tubular portion 15. For example, an additional clamping ring 19 (see FIGS. 1A and 2A) can be applied over the tubular portion 15 to create a stronger seal against the ribbed connector 16.

[0047] Delivery tube 39 connects to either a pressurized container 30 (FIG. 7) or pressurized bag 36 (FIG. 6) via an appropriate bag adaptor 35 (FIG. 7) or container adaptor 31 (FIG. 7).

[0048] The pressurized container 30 or the pressurized bag 36 are preferably under a pressure that is sufficient to deliver the flow of fluid into the mouth, but not so much as to make it unsafe. The preferred pressure is between 35 to 50 kPa or (5 to 7.25 psi), although greater pressures are also acceptable as long as the container and all components are sized to contain the elevated pressures. Lower pressure is also acceptable, although that may lead to lower flow volumes.

[0049] Bag 36 is preferably sized so that it fits on a human's body strapped around the waist and anchored by the sports players' pants (see FIG. 9). In this configuration, bag 36 fits around the players back and can add extra protection against impact from the rear.

[0050] Fluid can be delivered from bag 36 or any other suitable container by a motorized pump 40 (see FIG. 8). In this configuration, the valve 20 can be replaced by a tongue operated switch. The tongue operated switch may also be combined with suitable wiring and power source to activate motorized pump 40. The connection between the switch and motorized pump 40 may also include an electronic controller, wireless signal communication, and other suitable means for activating fluid delivery via control from the user's mouth.

[0051] Bag 36 can also be pressurized by the use of a mechanical pump 41 (see FIG. 8) that can be operated by the hand or any other suitable body part.

[0052] In an alternative embodiment, tubular portion 15 can be configured such that it is bent horizontally or vertically, or in any direction (see FIG. 5).

[0053] The foregoing description of the subject matter has been provided for illustration and description purposes only. The description is not intended to be exhaustive or to limit the subject matter to the only the form disclosed above. Other modifications and variations may be possible in view of the above teachings. The preferred embodiments were selected and described in order to best explain the principles of the invention and its application, and to enable others skilled in the art to make use of the invention in the various embodiments and modifications as may be suitable for their use. The appended claims are intended to include other alternative embodiments that may be suitable for the intended use, except as limited by the prior art.
