1. A water trap for a respiratory airline comprising:

  • an upper component open at a bottom end thereof, a lower component in the form of a water collection vessel releasably connectable to the upper component, inlet and outlet connection means on the upper component for connection to the airline, fixed disc means having a fixed position centrally of said open bottom of the upper component, means defining an upward opening of the lower component, and resilient sealing means in the region of the outer periphery of the upper component which, in an unstressed condition, will seal against said fixed disc means to close the bottom end of the upper component, the lower component having an upper periphery shaped so that when the upper and lower components are connected said upper periphery of said lower component will contact said resilient sealing means first to seal fluidtightly between said upper periphery and said resilient sealing means entirely about said upper periphery and then to displace said resilient sealing means upwardly, thereby to open the bottom of the upper component whereby a pathway will be provided for water to fall from the upper into the lower component only after said upper and lower components are fluidtightly sealed together.
