ABSTRACT:
The present invention provides unique improvements in an envelope having a front panel, a top flap, a bottom flap, and two side flaps. In one form, an improved bottom flap is provided with a substantially T-shaped portion having a leg glued to the side flaps, and having two wings extending laterally from the leg but not attached to the side flaps. The top flap is provided with cooperatively-spaced glued portions which may adhere to the wings but not to the leg. When the envelope is opened, the wings are torn from the leg. Another form of the improved envelope is top loading and bottom opening. In this form, marginal portions of the side flaps are provided with a plurality of inverted, substantially U-shaped slits. Glued portions of the bottom flap engage these side flap marginal portions. The central portion of the bottom flap is unglued and is not covered by the top flap. This unglued portion may be pulled downwardly to tear such slitted portions from the side flaps.
