The gist is to apply a non-removable pressure-sensitive adhesive, adhere a release paper that matches the properties of the adhesive to each top surface, and then cut it perpendicular to its longitudinal direction. .

する個所に接着したものである。In the illustrated embodiment, a releasable pressure-sensitive adhesive 2 and a non-releasable pressure-sensitive adhesive 3 are applied to both sides of a strip-shaped tough paper 1, respectively, and the adhesives 2 and 3 are applied to the upper surfaces of each adhesive, respectively. After polymerizing and pasting release papers 4 and 4', the paper was cut perpendicularly to the longitudinal direction to obtain gripping pieces 5. An example of the use of the devised gripping piece is to make a discontinuous cut in an envelope with a discontinuous annular cut 7 in the envelope body 6 and two continuous broken line cuts 8 and 8' at both ends of the cut. The lower half of the gripping piece 5 is adhered to the outer surface of the tongue-shaped portion 9 surrounded by the letter-shaped notch 7 via the pressure-sensitive adhesive 3, and the upper half of the gripping piece 5 is also attached It is adhered to a portion of the envelope body 6 located above the above-mentioned notch 7 via a pressure-sensitive adhesive 2.
本考案摘持片はその一半部に剥離可能な特性を有する感

により封筒の破裁部の端辺が外圧を受けて押圧等された
際に不用意に破裁したりする虞れ無からしめ得るのみな

を容易に摘持し得る等の諸効果を有するものである。One half of the gripping piece of the present invention has a pressure-sensitive adhesive that can be peeled off, and the other half has a pressure-sensitive adhesive that cannot be peeled off. Glue the lower half, which can be coated with non-removable pressure-sensitive adhesive, to the edge of the envelope tear, and use the same gripper to attach the upper half, which can be coated with removable pressure-sensitive adhesive, to the tear edge of the envelope. By gluing it to the outer edge, it is possible not only to prevent the edge of the torn part of the envelope from being inadvertently torn when it is pressed by external pressure, but also to prevent it from being torn when the envelope is opened. has the advantage of ensuring this by gripping and pulling the upper half of the gripping piece;
In addition, we used a removable pressure-sensitive adhesive to apply to the upper half of the gripper, so even if this part is glued to the outer edge of the torn part of the envelope, it can be peeled off extremely easily with the tip of a finger or toe. This has various effects such as being able to easily hold the same part.
