9892. Gunkle, K. E. April 20. Stoppers.-Relates to jars for containing fruit, preserved vegetable matter, &c. The jar a is formed with a shoulder c, and the neck e is tapered or curved to the mouth, where it is formed with a bead d adapted to hold the rubber, felt, or other washer f in position on the neck. The cover g is formed with a cylindrical flange g', which, when forced on the tapered neck, accommodates itself to the neck, as shown, and forms a tight joint with the washer f. The cover is applied when the contents of the jar are hot, so that, when cool, it is held in position by the external pressure. The cover may be removed by pulling up the projecting edge of the washer so as to admit air to the vessel, and it may be provided with a lug or finger-hold to facilitate its removal.
