## Title
Hydration mouthpiece

## Abstract

The invention is a mouthpiece that is connected to a tube connected to a bladder or liquid reservoir. The mouthpiece is constructed to remain comfortably in a user's mouth during sporting events or other activities, allowing the user to easily and effectively hydrate without distraction, and allowing the user to have both hands available.

## Background
TECHNICAL FIELD OF THE INVENTION
The field of the invention concerns a mouth protection piece that has the means to attach to a source of hydration.
BACKGROUND OF THE INVENTION
There are a variety of physical activities that require some form of protection of the mouth and teeth. These activities usually run a risk of damaging the mouth when it comes to collisions or accidents that would happen during said activities.
These forms of protection, i.e. mouthpieces or “mouth guards”, are normally very bulky means of providing maximum protection; users struggle to drink while the mouthpiece is inside the user's mouth.
The current standard mouthpieces/bite valves attached to tubes used for water bladders are not designed to continuously stay in the user's mouth. They slip out easily from the user's mouth, cause distractions, and users tend to cease using them while exercising, so they are forgotten, resulting in no hydration.
The invention discloses a mouthpiece that allows the user to attach a hose from a liquid reservoir, water pouch, bladder or a CamelBak® type of apparatus to the mouthpiece for easy water access.
The CamelBak and similar devices use a mouthpiece that includes a “bite valve” which opens while a user is biting on the end of the tube. This element of the CamelBak product helps keep the liquid from lowering back into the bladder between the user's sips. However this construction means that a user tends to release the CamelBak mouthpiece between sips, because the valve is not designed to remain in the user's mouth at all times.
SUMMARY OF THE INVENTION
The invention described here allows the user to safely place the mouthguard into the mouth, and easily and effectively hydrate for the remainder of a physical activity, reducing the effort necessary to keep the water accessible, and allowing the user to have both hands available and allow the user to focus his attention on other tasks.
The invention comprises a barbed tube intake and mouthpiece. The barbed tube intake accepts a tube that is attached to a water bladder. The mouthpiece is shaped to fit comfortably in a user's mouth with minimal effort on the part of the user for long periods of time. This invention makes it simpler for someone wearing a mouthguard to hydrate. For example, if there is a cyclist in a race and is wearing a water reservoir pack, this cyclist can easily hook the tube of the reservoir pack bladder to the invention and drink without removing the mouthpiece between sips, reducing distractions and increasing his performance.

DETAILED DESCRIPTION OF THE INVENTION
This hydration mouthpiece allows users to drink fluids through a hose attached to a fluid source without removing the mouthpiece between sips, as it is designed to remain in a user's mouth for long periods of time.
As seen in the figures, the invention comprises an Intake 13 and a Mouthpiece 15.
The Intake 13 comprises a Tube Connector 31 and a Flat Tube 17 which extends through the Mouthpiece to convey fluid into a user's mouth. The current embodiment comprises a Barbed Tube Connector 31 which creates a friction attachment to the typical elastomeric or silicon tube which sports bladders employ.
As shown by FIG. 2, the Intake 13 fits in a Cavity 23 shaped for it inside the Mouthpiece 15. The Mouthpiece 15 is shaped to fit comfortably in a user's mouth with minimal effort on the part of the user for long periods of time.
As seen in the figures, the Intake 13 serves as a path to convey fluid from the bladder tube to the user, connecting to the bladder tube by the Barbed Tube Connector 31, through the Intake Tube 17, and then through the Internal Mouthpiece Opening 33, inside a user's mouth while it is mounted inside the Mouthpiece 15.
The Intake 13 can also be affixed to a bladder tube in other ways than the barbed construction shown in FIGS. 1-5, though this approach is the best embodiment for those already using a conventional liquid bladder in sporting applications. However, in more rigorous applications, the Intake could include a threaded connection to the bladder tube, as shown in FIG. 6.
Also shown in FIG. 6 is an alternate construction for the Intake 13 that includes a Latch 19 on the end of the Intake that fits into the Mouthpiece 15. FIG. 2 includes an outline of the (non-latch) Regular Cavity 21 that matches the Intake 13 of FIGS. 4 and 5, along with the optional second outlined Latching Cavity 25 which matches the Intake 13 shown in FIG. 6.
Though the construction of the Latch 19 is rectangular in the figures, the invention is not limited to that shape. The point of the Latch 19 is to keep the Intake 13 from slipping out of the front of the Mouthpiece 19 by providing an anchor in the Mouthpiece 15.
The Mouthpiece 15 can be constructed in several ways. In one embodiment, the use of the Latch 19 at the end of the Intake 13 requires that the material used to create the Mouthpiece 15 be flexible enough that the Mouthpiece 15 can stretch to allow the insertion of the Intake 13, which in the current embodiment is constructed of much harder plastic, into the cavity of the Mouthpiece 15.
In a second embodiment plastic injection process is used in which the Intake 13 is molded and then set in a second mold which uses softer plastic to create the Mouthpiece 15. The approach effectively creates a one-piece product that is very rugged and not easily disassembled.
In the current embodiment, the invention is assembled by inserting the Intake 13 into the Internal Mouthpiece Opening of the Mouthpiece 15. But as previously mentioned, the invention is not limited to this type of construction and assembly.
Though the Intake 13 and the Mouthpiece 15 are described here as two different elements, a manufacturer could make a single part that includes both elements as one single formed part. The inventors of this product believe that there are benefits to a two-part construction, as a user will be more comfortable if the Mouthpiece Body has a lower durometer (more elastic) and allows a user's teeth to clasp the mouthpiece naturally either with or without a custom, “boil and bite” fit.
The Intake 13, however, must be hard enough to hold the bladder tube in place without danger of it slipping off. Because the two parts are designed for different tasks, the current embodiment uses two different types of materials and constructed separately but can be molded together by overmolding through thermoplastic injection as discussed supra.
In spite of the above, a manufacturer could form the device as one piece to save construction steps and reduce costs.
Because the Mouthpiece 15 remains in the user's mouth, the need for a bite valve is reduced, because the connection between the user and the tube is maintained naturally. When the user's mouth is closed, liquid inside the bladder tube cannot easily be replaced by air, since the user's mouth will tend to remain closed. However, the Intake 13 can be constructed of softer durometer material, so the natural force of a user's mouth closes the fluid path unless the user is actively intending to suck fluid out of the bladder.
The invention as described and shown is constructed of two components, the Mouthpiece 15 and the Intake 13. However, the invention can be created and constructed with one piece. In such a construction, FIGS. 1, 2, and 3 remain correct, except that no cavity for the Intake 13 is required, because the Intake 13 is simply part of the Mouthpiece 15.
Though FIG. 1 shows the invention to have an engagement with the upper teeth, the invention could engage the upper and lower teeth, similar to a boxing mouth guard.
Additionally, the invention could be comprised of multiple components, with the Mouthpiece 15 constructed of a lower half and an upper half, with the Intake 13 an inherent part of one of the halves, or even a three-part construction with the Intake 13 separate, and the upper and lower halves of the Mouthpiece 15 snapping together to hold the Intake 13 in place, and all three components replaceable.
Though the figures reflect a straight connection between the Tube Connector 31 and Intake 13, the elements are not required to be in the same horizontal plane. These two elements can connect at any angle.
