Regulator plug for the thermoformable dive mouthpiece

1. A plug for a dive mouthpiece, the mouthpiece having a passageway therethrough extending from a proximal, in-mouth port to a distal, out-of-mouth port, the passageway having a passageway shape, the plug comprising:

a plug portion having a plug-portion distal end, a plug-portion proximal end, and a plug-portion exterior surface configured to be complementary in shape to a distal portion of the passageway shape, whereby the plug portion seals off the distal portion of the passageway when inserted therein; and

a handle portion having a handle-portion proximal end integral with the plug-portion distal end, a handle-portion distal end, and a handle-portion exterior surface configured to be complementary in shape to a proximal portion of the passageway shape, whereby the handle portion seals off the proximal portion of the passageway when inserted therein.

2. The plug of claim 1 wherein the handle portion has an aperture extending therethrough.

3. The plug of claim 1 wherein the plug-portion proximal end has a raised discontinuity configured to interact with a furrow discontinuity of the distal portion of the passageway shape.

4. The plug of claim 1 wherein the mouthpiece is thermoformable at a first temperature and wherein the plug is not thermodeformable at the first temperature.

5. The plug of claim 1 wherein the plug portion has a plug-portion major axis extending from the plug-portion distal end to the plug-portion proximal end, and wherein the handle portion has a handle-portion longitudinal axis co-linear with the plug-portion major axis and has a handle-portion lateral axis radial to the plug-portion major axis.

6. The plug of claim 1 wherein the handle portion and plug portion are monolithic.

7. The plug of claim 1 wherein the handle-portion distal end has a beveled handle-portion distal edge.

8. The plug of claim 1 wherein the plug portion defines a lateral plug aperture extending laterally through the plug portion.

9. The plug of claim 1 wherein the plug portion defines a transverse plug aperture extending transversely through the plug portion.

10. A plug for a dive mouthpiece of the type having a passageway therethrough extending from a proximal, in-mouth port to a distal, out-of-mouth port, the passageway having a passageway shape, the plug comprising:

a plug portion having a plug-portion proximal end and a plug-portion distal end with a plug-portion-distal-end exterior surface configured to be complementary in shape to a distal portion of the passageway shape, a plug-portion major axis extending from the plug-portion distal end to the plug-portion proximal end; and

a handle portion having a handle-portion proximal end integral with the plug-portion distal end, a handle-portion longitudinal axis co-linear with the plug-portion major axis, and a handle-portion lateral axis radial to the plug-portion major axis.

11. The plug of claim 10 wherein the handle portion has an aperture extending therethrough.

12. The plug of claim 10 wherein the plug-portion proximal end has a raised discontinuity configured to interact with a furrow discontinuity of the distal portion of the passageway shape.

13. The plug of claim 10 wherein the mouthpiece is thermoformable at a first temperature and wherein the plug is not thermodeformable at the first temperature.

14. The plug of claim 13 wherein the handle portion and plug portion are monolithic.

15. The plug of claim 10 wherein the handle portion and plug portion are monolithic.

16. The plug of claim 10 wherein the handle-portion proximal end has a handle-portion-proximal-end exterior surface configured to be complementary in shape to a proximal portion of the passageway shape.

17. The plug of claim 16 wherein the handle portion includes a handle-portion distal end having a beveled handle-portion distal edge.

18. The plug of claim 16 wherein the plug portion defines a lateral plug aperture extending laterally through the plug portion.

19. The plug of claim 16 wherein the plug portion defines a transverse plug aperture extending transversely through the plug portion.

20. A plug for a dive mouthpiece, the mouthpiece having a passageway therethrough extending from a proximal, in-mouth port to a distal, out-of mouth port, the passageway having a passageway shape, the plug comprising:

a plug portion having a plug-portion proximal end, a plug-portion distal end, a plug-portion exterior surface configured to be complementary in shape to a proximal portion of the passageway shape, and a plug-portion major axis extending from the plug-portion distal end to the plug-portion proximal end; and

a handle portion having a handle-portion distal end integral with the plug-portion proximal end, a handle-portion longitudinal axis co-linear with the plug-portion major axis, and a handle-portion lateral axis radial to the plug-portion major axis.

21. The plug of claim 20 wherein the handle portion has an aperture extending therethrough.

22. The plug of claim 20 wherein the plug-portion distal end has a raised discontinuity configured to interact with a furrow discontinuity of the proximal portion of the passageway shape.

23. The plug of claim 20 wherein the mouthpiece is thermoformable at a first temperature and wherein the plug is not thermodeformable at the first temperature.

24. The plug of claim 23 wherein the handle portion and plug portion are monolithic.

25. The plug of claim 20 wherein the handle portion and plug portion are monolithic.

26. The plug of claim 20 wherein the handle portion includes a handle-portion proximal end having a beveled handle-portion proximal edge.

27. The plug of claim 20 wherein the handle portion has a handle-portion exterior surface configured to be complementary in shape to a distal portion of the passageway shape.

28. The plug of claim 27 wherein the plug portion defines a lateral plug aperture extending laterally through the plug portion.

29. The plug of claim 27 wherein the plug portion defines a transverse plug aperture extending transversely through the plug portion.
