An apparatus for making an envelope is also disclosed.

Abstract: Disclosed is to an easy-open envelope having a tear-line located within a length of the envelope's seam fastened to frangible portions of the envelope created by strategically placed perforations creating an envelope mailer with an integral opener that eliminates the need for using a knife or letter opener potentially damaging the envelope contents or using a finger which leaves the envelope ragged.

Abstract: A tear thread opening device disposed on a sealed fold line of an envelope or any other paper maid container. The tear thread is threaded along a chosen fold line of the envelope using traditional sewing techniques. The ends of the tear thread are lightly glued into the body of the envelope. In a second embodiment, the chosen fold line of the envelope or other paper maid container is only perforated and the tear thread is attached along the inside edge of the chosen fold line. In both embodiments ends of the thread must be lightly glued in to perforated fold line. If necessarily each end of injected into fold line tear thread could be attached to a small plastic tab, which would be located inside or outside overlapping closure flap. Grasping the tab or the corner of the envelope where the extremity of tear thread is glued, and pulling upward could easily open the envelope or any other paper maid container.

Abstract: An envelope pull opener includes a pair of pull tabs and a tearing filament. A single pull tab is attached to each end of the tearing filament. A peel-off adhesive surface is applied to one side of the pull tab. Preferably, the other side of the pull tab is structured to have a logo, picture, or other graphical representation applied thereto. The pull tab is preferably round, but could be any other shape such as square or triangular. In a second embodiment, the pull tab opener has a single pull tab on each end and an anchor tab attached in substantially the middle of the tearing filament. A third embodiment includes, a rigid envelope pull opener includes a first arm, a second arm, a pivotal connector, and a pair of pull tabs. A single pull tab is attached to an end of each arm. The other end of each arm is pivotal constrained by the pivotal connector.

Abstract: An improved envelope construction comprises in general an envelope unit, a sealing unit, and a tear strip unit. The envelope unit comprises an envelope body member having a flap portion with a central segment provided with the sealing unit and two generally triangular end segments separated from the central segment by strips of perforations. The sealing unit and the tear strip unit are operatively disposed on the flap portion. The tear strip unit extends across and has a length that can project beyond the flap portions. The opposite ends of the tear strip member are provided with globular elements to facilitate the user's grasp of a selected end of the tear strip to open the envelope.

Abstract: A tear string envelope with the envelope made of an integral blank of sheet material and formed such that the front and rear portion of the envelope is interconnected by side flaps folded inwardly so that side edges and a lower and an upper folding edge are formed under leaving an upper insertion opening which can be closed by a gummed closing flap. The tear string extends at the inner side of an edge, with the tear string adhered at an edge different from that of the closing flap.

Abstract: An envelope formed from a single sheet of paper includes a front portion, a top flap, two lateral side flaps, a bottom flap, a top folding edge, two lateral side folding edges, and a bottom folding edge, the lateral side flaps overlapping and adhering to the bottom flap to form the back portion of the envelope. The top flap will adhere to the back portion after contents of interest are inserted into the envelope. The envelope further includes an opening device in the form of a piece of thin line disposed inside the envelope. The thin line loosely extends along one of the folding edges with its first end attached to one spot near one end of that folding edge and its opposite second end attached to an anchor portion on the outermost flap near the other end of that folding edge. The anchor portion does not adhere to any other flap.

Abstract: A blank for a container and the container afford a structure wherein the adhesive closure for the container also forms a tear strip to allow easy opening of the envelope once it is sealed.

Abstract: The present invention relates to a paperboard envelope which utilizes a single strip of tear tape having adhesive applied to both sides for sealing and opening. The envelope structure includes starter elements in both the sealing flap and the panel to which the sealing flap is adhered for assisting in the opening function. The improvement lies in extending the starter elements beyond the side edges of the envelope body to provide starter tabs that can be readily grasped to open the envelope.

Abstract: An envelope with openable structure includes a front panel, a back panel and a closure flap. The front panel has a front inner and a front outer opposed surface, a front top edge, a front bottom edge, and a front first and a front second opposed side edge. The back panel has a back inner and a back outer opposed surface, a back top edge, a back bottom edge connected to said front bottom edge of said front panel to form a bottom folding line, and a back first and a back second opposed side edge connected to said front first and second side edges respectively to form a first and a second side folding line respectively. The closure flap is extended from said front top edge of said front panel and forms a front folding line therebetween for overlapping and adhering onto said back outer surface of said back panel.

Abstract: A mailing envelope (10) has a stick down closure flap (11) extending from a fold line (12) along the top edge of a front panel (20). The closure flap (11) includes a graspable tear-out tab (19) to which is adhered a flexible line member (18) which extends across and is adhered to the envelope internally thereof. The envelope (10) may be opened by grasping the tab (19), with the line member adhered thereto, and pulling the tab (19) and the line member (18) away from the envelope to cause the line member (18) to tear through the envelope along the length of the line member. Preferably the line member (18) is secured to the flap (11) along it fold line (12).
