TITLE: DISPENSING CLOSURE UTILIZING A SEALING ELEMENT SUPPORTED BY A WASHER SPRING ABSTRACT The term "dispensing closure" designates closures which are constructed so as to utilize a spout movably mounted on a cap or related structure so as to be capable of being moved between an open position in which a passage through the spout is aligned with an opening through a cap and a closed position in which a portion of the spout closes off this opening. Such a dispensing closure can be improved by constructing the cap so that the portion of the cap immediately around the opening is shaped as a washer spring and by constructing both the cap and the spout so that this spring resiliently biases a sealing surface against the spout.
