DISPOSABLE SPITTOON COVER

摘要

A disposable spittoon cover for a paper cup or the like includes a conical tunnel with an entry hole near or at an apex of the tunnel, and an integral, resilient flap covering the entry hole. The flap may be formed at a slight angle to the tunnel walls, in the range of about 5° to 20°. The disposable cover may further include two or more concentric grooves configured for fitting snugly to rims of disposable cups, with each of the grooves configured to fit to a cup of different diameter. The grooves may be separated and spaced apart from one another in a direct transverse to a plane defined by any one of the circular grooves (e.g., a “vertical” direction), by one or more interposed annular ring walls.

主权项

1. A cover for a container, consisting essentially of a contoured, resilient sheet material of one piece having contours defining:
a circular groove disposed around and adjacent to a circular periphery of the sheet material, the groove concave towards a first side of the sheet material; a conical tunnel disposed at a circular center of the sheet material, having an open conical base oriented towards a second side of the sheet material opposite to the first side; and a flap over a conical vertex of the conical tunnel, the flap defined by a perimeter cut through a lateral surface wall of the conical tunnel and joined to the lateral surface wall by a resilient hinge piece.
