Abstract
284,888. Meyer, F. March 26, 1927. Drawings to Specification. Modified for opening.-A glass vessel such as a food container, vial, ampoule, &c. is provided with a cracking-line to enable it to be opened by breaking off the neck or other part. The glass, while hot during manufacture, is chilled by contact with a cold body. As a result, the finished vessel is strained along the line of chilling and a slight injury to the glass at this point causes it to crack-off cleanly along the line.
