Abstract: The blank for making a folder is formed with a rhombic-shaped tab on each side flap. When each flap is folded over or under an extension folded onto the main section of the blank, the rhombic-shaped tab reinforces the corner of the pocket formed by folding over each flap onto a folded up extension.

Abstract: The blank for making a file folder or mailer has side flaps that have a tab at each end. One tab serves to reinforce a bottom corner of the file holder to avoid popping out when filled to capacity and the other tab is rounded for extending above the front panel.

Abstract: The mailer is made from a single blank. In one embodiment, the side flaps are folded over a front panel followed by folding over and securing of a back panel to the said flaps to form the mailer. The closure panel is folded over the front panel to close the mailer. In another embodiment, a back panel is folded over a front panel followed by folding over and securing of the side flaps to the back panel to form the mailer. The closure flap is folded over the back panel to close the mailer. In another embodiment, a blank forms a center seam mailer. Each embodiment has an improved corner construction.

Abstract: The pad holder is constructed with an expandable pocket to receive a pad of paper or the like and with a fold over front ply to retain the pad of paper in place. A pad of paper may be retained wholly within the pocket while the front ply is secured to the pocket to retain the pad in a secure condition. In another embodiment, the expandable holder is formed to receive photo prints.

Abstract: The pocket folder has a closed pocket on the back section with each side of the closed pocket being freely expandable. Flaps that form the ends of the closed pocket are separated by a fold line into two contiguous parts that are hinged to each other to allow expansion of the pocket. The pocket folder is fabricated from a one-piece blank of any suitable material such as paper, paperboard or plastic and has score lines on at least the back section to permit expansion when materials are inserted into the closed pocket.

Abstract: The flat oversize mail piece includes an envelope of expandable nature, a flexible insert within the pocket of the envelope and an item that may be rigid or non-rigid. In one embodiment, the insert is provided with a cutout that is asymmetrical to one side of the insert and envelope to matingly receive the item being shipped. In another embodiment, the insert is a thin plastic tray having a recess to receive the item being shipped and a plurality of cavities interconnected by thin webs that impart flexibility to the package.

Abstract: A single blank is used to make an expandable envelope construction having four side edges which can expand as the envelope construction is filled to capacity. The blank is provided with horizontal and vertical score lines and fold lines which permit the sides and bottom of the construction to collapse inwardly while the pocket enlarges in thickness and decreases in height and width. The blank has side flaps with corners at the ends which are overlaid by the back panel and closure panel in an unsecured manner to maintain the envelope in a sealed condition when expanded.
