Hot drink infuser with vacuum flask - prepared drink drains into flask lining case with parts screwing together to teapot shape

摘要

On infusion, the liquid drains into a vacuum flask, which lines a case whose parts screw together and take the general form of a teapot, with handle and spout. When the teaot is in position in the machine, a hollow in its base fits over a prominence in the base of the machine. The conical infusion vessel hangs in the machine directly above the teapot. When both are in place, they are in communication over a pair of valves. A spring valve in the centre of the teapot lid lifts a gravity valve at the bottom of the infusion vessel. When the teapot is removed, both valves close, the one holding back drips from above, the other sealing the teapot lid.
