Improvements in or relating to envelope assemblies.

摘要

A stuffed sealed envelope assembly has a free insert immobilized therein against shifting by means of adhering material (26, 27) provided on confronting surfaces both the front and back of the envelope and so characterized that the material will stick only to itself and not to the insert. Such material is placed in contact with the insert while remaining unattached therefrom so as to snugly hold the insert in registry within the envelope. Removal of an envelope stub facilitates opening and extraction of the insert.
