Abstract
441,423. Envelopes &c. ELLENS, W. E., Tresco Brow, Chesham Road, Berkhampsted, and DICKINSON & CO., Ltd., J., Apsley Mills, Hemel Hempstead, both in Hertfordshire. Oct. 26, 1934, No. 30742. [Class 146 (ii)] In an envelope or the like of the kind provided with self-adhesive sealing- material, the latter consists of a solution of rubber latex applied in the form of stripes to the exterior surface of the back of the envelope adjacent the mouth and the interior surface of the closing flap, there being an intervening flap which is adapted to extend beyond the mouth and the closing flap and to fold upon the stripe on the back to protect it from contact with the stripe on the closing flap. Such envelopes can be packed or printed without rendering them unfit for use. As shown, a bag-form envelope is provided with a flap c<1> consisting of a piece of envelope material which may be attached to either the inner face of the front or the back of the envelope so as to extend over the stripe d of adhesive on the closing flap e, whereby the stripe d cannot contact the stripe a on the back of the envelope. In a modification, the protective flap consists of an extension of the back of the envelope. The protective flap may be perforated for folding at the mouth of the envelope, and for subsequent removal ; if desired, the flap may be folded inside the envelope prior to sealing.
