ABSTRACT:
This invention solves the problem of disposal of used coffee membrane filters and wet coffee grounds neatly with decreased probabilities of spilling coffee grounds on the floor, table or dumping them loose in a trash container. Thus, several embodiments provide different ways to close and secure the open top of the filter membrane after insertion of coffee grounds into the filter for making coffee, thereby to provide a closed unit that can be disposed of without spilling the beans. Thus, drawstrings or adhesive tabs may be provided in the rim of the filters for closure, or additional flaps or cover sheets may be attached to the rim of the filter to close the open filter mouth.
