21,361. Pattersom, E. J. Oct. 5. Envelopes.-To enable envelopes to be more easily closed, and to prevent them from being fraudulently opened by the insertion of a knife beneath the flap, the gummed edge of the closing flap a is punched, or cut, as shown in Figs. 1 and 3. The gummed edge thus treated being more flexible than a continuous edge, tends to adhere better to the body of the envelope. The notches or holes may be of any convenient form.
