Claims
- 1. A signal coupling for a humidifier container having a gas inlet duct terminating in an externally threaded male inlet coupling which comprises
- an internally threaded elongated member adapted to threadingly engage said male inlet coupling and provided with an upstanding protuberance having a head portion and a stem portion, said stem portion defining a main gas passageway therethrough, an outwardly flared signal gas passageway communicating with the main gas passageway and a substantially planar land region on the peripheral surface of the stem portion adjacent to the signal gas passageway; and
- a flexible, elastic sleeve situated in tension about the peripheral surface of the stem portion and occluding said signal gas passageway as well as said planar land region.
- 2. The signal coupling of claim 1 wherein said planar land region is adjacent to and above said signal gas passageway.
- 3. The signal coupling of claim 1 wherein the peripheral surface of the stem portion surrounded by said flexible sleeve has a relatively greater circumference at one peripheral edge of the sleeve as compared to the other peripheral edge of the sleeve so that one peripheral edge of the sleeve is tensioned more than the other peripheral edge of the sleeve.
