Abstract
Abstract A disposable infusion bag capable of containing tea or the like which is immersible in a cup of hot water and suspended from a crossbar resting on opposite sides of the rim of the cup. The crossbar is in the form of an inverted "V" comprised of a squeezable pair of plates so that the infusion bag can be drawn up into the apex of the crossbar to squeeze off excess water before disposal. The crossbar is also designed to fit various sizes of cups and contains a suitable hole for passage of a thread or filament of plastic or other supporting means.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
120 words
An infusion bag assembly for tea or other infusible material comprising a porous bag, resilient means for supporting said bag, said resilient supporting means comprising a filament slidably secured to a crossbar through a hole at the apex of said crossbar, said crossbar being adapted to fit over the rim of a cup, and comprising two elongated plates adapted to squeeze excess water from the infusion bag, said crossbar further being in the shape of an inverted "V" so as to provide visual observation of the interior of the cup without requiring its removal and further having serrated edges adapted to fit over the opposite portions of the rim of a cup and balance itself upon cups of various sizes.
