Abstract
Abstract A paper extractor including a support member in the form of a collar of a small wall-thickness having at its lower end two support legs facing each other, a filter attached to an inner surface of the support member, and coffee packs each including coffee powder sealed in a bag of filter cloth or filter paper. The support legs of the support member are each formed with folds in the form of a letter V to allow the support legs to be deformed and project outwardly when they are bent at the folds. By replacing the coffee pack by a new one, the paper extractor can be used several times before it is discarded, and the deformable support legs enable the paper extractor to be stably supported on the upper edge of a coffee cup.
