GRAVITY ASSISTED COLLECTION DEVICE There are described a device and method constructed to collect a liquid into a device so that the liquid is first drawn in to an intermediate point by capillary attraction only, and then from that intermediate point further by gravity. The device features two apertured portions connected at said intermediate point so as to be angled to each other. The means in the first portion that provide the capillary attraction through its aperture comprise preferably oppositely disposed surfaces spaced a distance no greater than that which will maintain capillary flow into that portion through the aperture; The means of the second portion that provide gravity flow further into the device from the intermediate point are a spacing of the opposed surfaces a distance effective to allow gravity to passively overcome any surface attraction caused by said opposed surfaces, and the inclination of that portion to drop below the horizontal plane extending from the intermediate point. |
