Self-open envelope

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. This action will cause the tear thread to tear thru the fold line thereby easily opening the envelope or any paper maid container.

Description

[0001] The present invention relates to all sizes mailing envelopes, paper wrappers, utility and industrial boxes or any paper made containers. Design of Self Open Envelope calls for materials such as fabric and paper to be utilized as its major components. This first and original concept was born on traditional sewing principles, identically as we sew our clothing FIG. 1 (3). A sewer head needle FIG. 1 (4) injected a fabric tearing thread FIG. 1-2 (2) in to paper, same time inside and outside, along one of four folding lines of overlapping elements, of the envelope. Each end of injected in to fold-line tear-thread must be lightly glued in to body of the envelope FIG. 2 (3) to prevent thread from sliding out of your fingers or other end, at the time, when One will pull thread upward to open envelope. If necessarily the thread would be designed a little longer then actual size of an envelope, box . . . Extended ends of the thread could be attached to a small plastic tab FIG. 2 (4), which would be in placed inside or outside overlapping element of the envelope, box or any paper maid container. The tab could be felt through the paper of the envelope and would allow the recipient of the letter, card or box easily determine where the thread was positioned. Otherwise the thread would be chosen in variations of colors, or simply, closest area to saw thru fold-line must be colored along thereof area. To use Self Open Envelope, One must grasp and thereof sew thru, small area, the corner of the envelope FIG. 6 (3) and pull thread upwardly, in slow or mild motion. The pressure of the thread, against perforation, would cause fold line to break open fast, easy and with out extra paper waist.

[0002] Modification of concept two almost identical to modification of concept one. Chosen, one of four, folding lines overlapping elements of the envelope, box or any paper-maid container will be only perforated with in small holes size of utility sewing needle, tear thread is then attached along the surface perforated fold-line, from inside one of four closure flaps of the envelope, box . . . FIG. 2. If necessarily the thread could be designed a little longer then actual size of the envelope. Each end of the thread must be lightly glued in to perforated fold line FIG. 1 (3), from inside overlapping element. To make this concept work and open envelope, box . . . One must do the same as it explains in concept one.

BRIEF DESCRIPTION OF THE DRAWINGS

[0003] FIG. 1 is a perspective view showing a sewing head needle threading a sewing thread same time inside and outside a folding line, one of four, overlapping elements in an envelope.

[0004] FIG. 2 is a front view of an envelope; with an open flap (5) including the tear thread (2) glued ends of the thread (3) and small plastic tab;

[0005] FIG. 3 is front views of an unfolded and unsealed box (1) including the tear thread (2) the small plastic tab (3) and threaded fold lines;

[0006] FIG. 4 is a perspective view of a partially opened box (1) including tear thread (2) the small plastic tab (3) and threaded fold lines.

[0007] FIG. 5 is a perspective view of a partially open sealed envelope (1) tear thread (2) with a plastic tab (3)

[0008] FIG. 6 is a perspective view of a partially open envelope (1) tear thread (2) ripped of corner of the sealed envelope where the extremity of the tear thread is glued (3).

Claims

1. A tear thread opening device in combination with an body of the envelope or any paper-made container. A sewing head needle is used to sew a thread, along both the inside and out side surface of a chosen fold line one of four overlapping elements of the envelope, box, or any paper-made container. The envelope, box or any paper-maid container can then be sealed. When one end of the tear thread is pulled away and upwardly, the thread will pull against and tear the chosen fold line, thereby opening the sealed envelope.

2. A tear thread opening device in combination with an envelope or any paper-maid container. A chosen fold-line of the envelope, box, or any paper-maid container is perforated. The tear thread is then attached along the inside of perforated fold line. The envelope, box or any paper-maid container can then be sealed. When one end of the thread is pulled away and upwardly, the thread will pull against and tear the perforated fold line, thereby opening the sealed envelope.
