Abstract
756,314. Envelopes; labels. WALSH, W. H. Dec. 9, 1954 [March 10, 1954], No. 35654/54. Classes 73 and 146(2) In an envelope comprising an opaque portion 5 and a transparent or translucent portion 10, the latter consists of a sleevelike container of thermoplastic material open at one end and hermetically sealed at the opposite end 12 by the application of heat and pressure, the sealed end having a marginal portion 13 extending beyond the seal 12 secured to one edge of an opaque letter envelope or label 5. The portions 5 and 10 may be joined by stitching 11, and heat and pressure may be applied across the stitching as indicated at 14. When the article has been inserted in portion 10 the latter is sealed as at 15, e.g. by heat and pressure or adhesive.
