Abstract
28,597. Lorenz, W. A. Dec. 28. Stoppers. -In hermetically closing jars, tumblers, &c., by a vacuum process, the sealing- caps and washers are so combined that the washers are secured against displacement during handling and sealing. The invention is shown applied to a tumbler. The lower edges b of the rim of the cap a, Fig. 1, is turned in to form a groove c, which receives the lower edge of the washer g, upon which, for further security, it may be pinched, as shown in Fig. 5. The washer is rhomboidal in cross-section, as shown, and is adapted to form a lining for a flared portion e of the rim of the cap. The cap a is also provided with an inner cover m, the cylindrical portion of which fits a groove n in the cap a, and extends downwards to form a shoulder l, which further retains the washer and prevents it from being crowded upwards when applied to a vessel. The cover m. may be waterproofed paper, glass, sheet metal, or other suitable material. In the modification shown in Fig. 6, the washer is made of uniform cross-section and is sprung into the cap, to the contour of which it may be moulded if desired. The washer may be held by friction alone ; or, an inner cover s may be used.
