Abstract
The invention is directed to a liquid strainer and a blank for forming the strainer. The strainer has a conical shape with an apex portion completely surrounded by a filtering cloth and folded from the blank to exclude any unfiltered passageway. The blank has the general shape of a disk truncated about two angularly spaced radial sides, the angle between the sides allowing for formation of a conical shape when the sides overlap. A circular aperture is partly carved at the intersection of the two sides, the remaining portion of the aperture is surrounded by a ring extending from the sides. The aperture is covered by a filtering cloth peripherally adhering to the blank and the ring. When the blank is folded, the ring forms and continuously extends from the latter. The filtering cloth which is glued to the ring completely closes any passageway through the folded cloth.
