Abstract

5992. Lovell, A. March 16. Stoppers.-Relates to a method of hermetically closing the metal lids or covers of metallic, earthenware, glass, &c. boxes, cases, or canisters. The case 1 is provided with a U-shaped groove 2 around the top, to receive a rubber &c. ring, on which rests the downwardly-extending flange 5 of the lid or cover 4. In the lid or other part of the case are formed one or more orifices 6, adapted to be closed by a valve or diaphragm 9 located in a casing 7 provided with an opening 8. In closing the case, the nozzle of a pump &c. is placed over the orifices 6, and air is exhausted from the interior of the case. The pressure of the atmosphere forces the lid into contact with the ring 3 so as to form an airtight joint. The orifices 6 are closed by soldering &c.
