Mouth guard with breathing and drinking aperture

1. A mouth guard comprising:

a pair of spaced-apart molar receiving members having opposite upper and lower biting surfaces;

forward end portions of the molar receiving members being positioned in a spaced-apart relationship with one another, defining a fluid gap;

an outer wall having opposing forward and rearward surfaces; the rearward surface of the outer wall being shaped to confront an exterior surface of a user's lips;

an inner wall, positioned between the molar receiving members and the outer wall; a rearward inner wall portion being shaped to extend along at least a portion of a length of an outer edge portion of the molar receiving members and a forward inner wall portion being shaped to extend along at least a portion of a width of the mouth guard, forward of the fluid gap between the molar receiving members; the inner wall having opposing forward and rearward surfaces; the forward surface of the inner wall being shaped to confront an inner surface of the user's mouth; the rearward surface of the inner wall being shaped to confront forward surfaces of the user's teeth; and

a conduit extending between the inner and outer walls such that the forward inner wall portion is longitudinally separated from the rearward surface of the outer wall by a gap defined by a length of the conduit; the conduit having at least one open passage that extends through opposite end portions of the conduit; the open passage penetrating the forward inner wall portion and outer wall;

the fluid gap having a width, along an entire length of the fluid gap, that is at least as wide as a width of the open passage such that fluid may flow along a linear pathway, from the open end portion of the conduit passage adjacent the inner wall, through the fluid gap.

2. The mouth guard of claim 1 further comprising:

a conduit passage opening, associated with one end portion of the conduit and the outer wall; the conduit passage opening being configured as an obround aperture.

3. The mouth guard of claim 1 wherein:

the rearward surface of the outer wall has a spherical shape that generally conforms to a user's lips; the outer wall being resiliently deformable and positioned to displace, absorb, or deflect energy from impacts against the user's lips.

4. The mouth guard of claim 1 further comprising:

a plurality of ribs extending from opposite upper and lower biting surfaces of the molar receiving members.

5. The mouth guard of claim 1 further comprising:

separate retaining walls that extend above and below the upper and lower biting surfaces of the molar receiving members, along opposite sides of the molar receiving members; the retaining walls terminating at, and not spanning, the fluid gap.

6. The mouth guard of claim 1 wherein:

the open passage that extends through opposite end portions of the conduit is unobstructed such that a continuous fluid pathway is defined from the outer wall of the mouth guard through the fluid gap.

7. The mouth guard of claim 1 wherein:

a forward surface of the outer wall has a convex shape that is positioned to absorb or deflect impacts against the user's lips.

8. A method for passing fluid through a mouth guard, the method comprising:

positioning a mouth guard within a user's mouth such that:

a pair of spaced-apart molar receiving members of the mouth guard are disposed between opposing molars in the user's mouth; opposite upper and lower biting surfaces of the molar receiving members confronting the opposing molars; forward end portions of the molar receiving members being positioned in a spaced-apart relationship with one another, defining a fluid gap;

an outer wall of the mouth guard is positioned so that a rearward surface of the outer wall confronts an exterior surface of the user's lips;

an inner wall of the mouth guard, positioned between the molar receiving members and the outer wall, a rearward portion of the inner wall being shaped to extend along at least a portion of a length of an outer edge portion of the molar receiving members and a forward portion of the inner wall being shaped to extend along at least a portion of a width of the mouth guard, forward of the fluid gap between the molar receiving members; the inner wall being positioned so that forward surfaces of the forward portion and rearward portion of the inner wall confront an inner surface of the user's mouth, a rearward surface of the rearward portion of the inner wall confronts forward surfaces of the user's molars, and the forward portion of the inner wall confronts forward surfaces of the user's incisors; and

a conduit of the mouth guard extends between the inner and outer walls of the mouth guard such that the forward inner wall portion is longitudinally spaced from the rearward surface of the outer wall by a gap defined by a length of the conduit extending between the forward inner wall portion and outer wall;

the fluid gap having a width, along an entire length of the fluid gap, that is as wide as or wider than a width of a rearward opening of at least one conduit passage that extends through opposite end portions of the mouth guard conduit;

directing fluid through the open conduit passage and into the user's mouth such that the fluid flows along a linear pathway from the rearward opening of the conduit passage, through the fluid gap.

9. The method of claim 8 further comprising:

positioning an end portion of a straw in open fluid communication with the open conduit passage such that the straw does not contact lips of the user; and

directing fluid through the straw, the open conduit passage, and into the user's mouth while the mouth guard is positioned within the user's mouth.

10. The method of claim 8 further comprising:

positioning an end portion of a drinking container closely adjacent to the open conduit passage; and

directing fluid from the drinking container, through the open conduit passage, and into the user's mouth while the mouth guard is positioned within the user's mouth.
