ABSTRACT:
A gingival cord container cap is disclosed featuring a cord dispensing gate mechanism formed by cooperating parts of a pivoted dispensing spout and a cap base in which the spout is socketed. Cord threaded out of the container through a hole in the cap base and through the spout may be withdrawn freely when the spout is swung into alignment with the hole in the base (i.e., the gate-open position). As the spout is pivoted out of such alignment (closing the gate) the cord is pinched and held, so that it may be cut off flush with the aperture of the spout, protectively retaining the remainder in the container. Swinging the spout back into aligned position causes a short segment of the pinched cord to be automatically projected out of the tip of the spout where it can be manually grasped for withdrawing additional cord from the container as needed.
