Abstract (en)
The invention relates to ''continuous window'' envelopes intended for commercial uses. This device makes it possible to avoid the problems linked with the precise positioning of the address. Envelope consisting of two parts, a rectangular base sheet (1) with two transverse folds (3) (Fig. 1) forming two lateral wings (2) adhering to a white glassine (translucent) sheet (4) (Fig. 4) or other transparent material making a window (5) which spans the entire length of the envelope (Fig. 5). The window (5) made from white glassine (translucent) paper extends at its two ends, forming the folding edge (6) adhering to the back of the base sheet, and the folding edge (7), led a self-adhesive strip, turns over on the back of the envelope, forming the closure.
