The first wall 14 incorporates an aperture 30 therethrough. A flexible, tubular-shaped member 60 is provided, having first and second ends 61 and 62. The first end 61 is coupled to the second end wall 16 and the opposite end 62 is adapted to fit over the mouth and nose. An inlet valve 36 is provided which is adapted to allow humidified air from the interior of the container 12 to the interior of the member 60. A vent valve 33, biased to the closed position, is provided which is adapted to allow exhausted air in the member 60 to pass into the interior of the container 12. A passage assembly 40 coupling the vent valve 33 to the interior of the container 12 is also provided. An open-celled foam member 42 is mounted within the container 12 between the aperture 30 and the inlet valve 36 adapted to receive and hold water. The passage assembly 40 passes through the foam member 42 which completely separates the inlet valve 36 from the aperture 30. The side wall 20 is releasably engageable from the second end wall 16 with a detent assembly 22, 24 adapted to releasably secure the side wall 20 to said second end wall 16. Additionally, an alignment assembly 52 is provided so that the side wall 20 is secured to the second end wall 16 with the vent valve 33 aligned with the passage assembly 40.
