DETAILED DESCRIPTION

[0049] The following discussion provides example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

[0050] FIGS. 1-11 show various views of a hydrating mouthguard system 100 in an open state. Mouthguard 100 has a mouthpiece 103 and a housing 105. Mouthpiece 103 is sized and dimensioned to fit withing a user's mouth like a typical athletic mouthguard. For example, mouthpiece 103 has a curved shape that matches a person's dental arch. Mouthpiece 103 also has curved side walls on the upper surface that are sized and dimensioned to wrap around, and protect, a person's maxillary teeth. It is contemplated that mouthpiece 103 could also have curved side walls on the lower surface that are sized and dimensioned to wrap around, and protect, a person's mandibular teeth. Mouthpiece 103 also has a plurality of protrusions on the upper surface to provide a gripping texture for the teeth.

[0051] Housing 105 is coupled to the front of mouthpiece 103. Housing 105 is positioned outside the user's mouth when mouthpiece 103 is worn within the user's mouth. Housing 105 has a cover 111 that is hingeably coupled with a backing 113 via a flexible connector 112 (e.g., bridge). Cover 111 is transitionable between an open state and a closed state. FIGS. 30-33 show housing 105 in the closed state. Cover 111 has a pair of latches 115 that removably attach to a pair of tabs 114 on backing 113 to secure cover 111 in the closed position. It is contemplated that other removable attachments can be used to secure cover 111 in the closed position without departing from the inventive concepts disclosed herein.

[0052] Cover 111 and backing 113 define an interior space when in the closed state. The interior space is sized and dimensioned to hold a container 107 (e.g., reservoir) filled with a hydrating fluid.

[0053] FIGS. 12-20 show various views of container 107. The rear surface of container 107 has an opening 118 and a pair of ribs 119. Opening 118 is sized and dimensioned to fit inside inlet 123 on backing 113 of housing 105. Ribs 119 are sized and dimensioned to nest with a pair of grooves 120 on backing 113. The nesting of ribs 119 inside grooves 120 help to keep container 107 from shifting when placed inside housing 105. Ribs 119 also help to prevent the formation of air bubbles when container 107 is being refilled with a hydrating liquid. Container 107 is refilled with a hydrating liquid by placing a funnel in opening 118 and pouring the liquid into the funnel. After container 107 is filled with a liquid, the funnel is removed from opening 118 and a tube 110 is partially inserted into opening 118, as shown in FIG. 35.

[0054] FIGS. 21-29 show various views of tube 110. Tube 110 has an annular flange 133 disposed between a first end portion 132 and a second end portion 134. Annular flange 133 is sized and dimensioned to fluidly seal with opening 118 of container 107. More specifically, tube 110 has a reduced outer diameter section 136 that is disposed adjacent to annular flange 133, and a shoulder 137 (e.g., rib) adjacent to reduced outer diameter section 136. Opening 118 of container 107 has a reduced inner diameter 117 that is sized and dimensioned to fit on reduced outer diameter section 136 of tube 110. When second end portion 134 is inserted into opening 118 of container 107, reduced inner diameter 117 of opening 118 tightly grips onto reduced outer diameter section 136 of tube 110, and annular flange 133 and shoulder 137 help to keep reduced inner diameter 117 in place and create a fluid seal. Tube 110 is made of a flexible material and second end portion 134 has a plurality of ribs, corrugations, or pleats, that allow tube 110 to bend inside container 107. The tip of second end portion 134 has a large inlet 135 (e.g., opening) that allows the hydrating fluid to flow into tube 110. The tip of first end portion 132 has a pressure valve 131 (e.g., slit, duck valve) that remains closed until the hydrating fluid reaches a threshold pressure caused by pressing the front of housing 105. Housing 105 has sufficient flexibility to transfer pressure to container 107. Tube 110 acts as a closure for opening 118 and prevents the hydrating liquid from escaping until container 107 is pressed.

[0055] Once tube 110 is partially inserted into container 107, first end portion 132 of tube 110 remains outside of container 107. First end portion 132 is sized and dimensioned to fit inside channel 122 in mouthpiece 103, as shown in FIG. 33. Channel 122 has an inlet 123 (e.g., opening) on the front interior surface of backing 113 and an outlet 121 (e.g., opening) on the rear exterior surface of mouthpiece 103. First end portion 132 has a taper angle that matches the taper angle of the inner surface of channel 122 in mouthpiece 103. Annular flange 133 also has a taper angle that matches the taper angle of channel 122. Annular flange 133 is sized and dimensioned to tightly fit with an internal shoulder 124 of channel 122 to create a fluid seal. The length of first end portion 132 is long enough such that valve 131 extends outside of mouthpiece 103 and into the user's mouth.

[0056] Mouthpiece 103 also has channels 126 that fluidly couple with channels 127 on the rear surface of backing 113. Channels 126 and 127 allow a user to breath through the user's mouth even when the lips are closed around mouthpiece 103.

[0057] FIGS. 30-33 show various views of hydrating mouthguard system 100 in a closed state, with container 107 disposed inside housing 105, and with tube 110 inserted inside housing 105 and channel 122. The cross-sectional view shown in FIG. 33 illustrates the tight-fitting fluid seal between container 107, tube 110, and channel 122.

[0058] FIG. 34 shows an exploded cross-sectional view of hydrating mouthguard system 100. FIG. 35 shows a cross-sectional view of tube 110 inserted inside container 107.

[0059] Removable valve makes it easier to clean the inside of the housing because there are no small/tight spaces to for liquid and bacteria to hide. Duck valve holds in liquid until squeezed. Containers are refillable and reusable. Funnel is used to refill.

[0060] One should appreciate that the disclosed subject matter provides many advantageous technical effects including providing hydration to a person while engaged in physical activity without the need for a break. The hydrating mouthguard disclosed herein allows a user to dispense a hydrating fluid from a reservoir within a housing of the mouthguard by simply pressing against the housing. The hydrating mouthguard also has a removable container/reservoir that can be refilled using a funnel. In addition, the hydrating mouthguard includes a removable tube with a valve that is used to close the opening of the container to prevent liquid from pouring out while loading the container into the mouthpiece. The tube also has an annular flange and reduced outer diameter that fluidly seal with the opening of the container to prevent leaking once the container is loaded into the housing of the mouthguard. The mouthguard design also eliminates small spaces (e.g., crevices), making it easy to clean and safe to reuse.

[0061] It should be noted that the mouthguard systems discussed above can be effectively used by individuals in sports, medical, and/or military settings. It is contemplated that the substances within the container can vary depending on the setting. For example, the substance within the container can be nutritional and/or sports enhancement in a sports setting, and dietary, medicinal, nutritional, and/or herbal in a medical or military setting.
