Abstract: A mailing device (10) comprises a blank (12) of foldable material defining at least two panels (14, 16) separated by one or more fold lines (18). At least two of the panels (14, 16) have removable edge regions (24, 26, 30) and an inner surface of the removable edge regions of a first of the panels (14) is coated with adhesive to enable the edge regions to be bonded to corresponding removable edge regions of another panel when the blank is folded. A sheet of material (36) is affixed to an inner surface of one of the panels (14) so as to cover an inner region of the panel within the removable edge regions. The sheet (36) may be printed on with a security hatching. Releasable tape (34) may be applied over the adhesive and the sheet (36) may be made of the same material as the release tapes. Various other mailing devices are also disclosed.

Abstract: A mailing device (210) has a body (215) with a window aperture (216). The aperture is covered by a film of transparent material bonded to the body. At least one line of weakness (128) is formed in the body at least partially encircling the film to enable the film to be separated from the body for recycling. The line of weakness (128) may be configured to define a strip (236) that extends across a front wall of the device. The strip (236) can be opened by tearing along the line of weakness to gain access to the interior of the device and to allow easy removal of the film. Alternatively, the line of weakness (128, FIG. 3) may completely encircle the film and define a tab portion (124, FIG. 3). In further alternative embodiments, the film (18, FIG. 1) has a tab portion (24, FIG. I) that is pulled to separate the film from the body. The film may be bonded using a peelable adhesive and may be bonded to an outside surface of the body.
