Abstract

(57) [Summary] [Purpose] To provide an envelope designed to make it easy to open. [Structure] Extend the back upper half plate and back lower half plate to the upper and lower edges of the front side plate through the upper and lower bent portions, and fold the back lower half plate to the back side of the front side plate at the lower bent portion. The upper and lower back half plates and the front and back plates are fastened to each other to form a bag part, and the top end of the back half plate is cut into an isosceles triangle shape. Apply pressure-sensitive adhesive to the inner surface of the parallel lines, and apply release paper to this application part so that it can be peeled off, and fold the upper back half plate at the upper bending part on the outer surface of the lower back half plate. In this case, a release agent is applied to a portion of the pressure-sensitive adhesive which is close to the apex of the isosceles triangular cut.

And the lower half half plate 5 and the left and right side edges of the front side plate 1 are fastened to each other to form a bag portion 6, and the tip of the back side upper half plate 4 is an isosceles triangle. Cut into a shape, and pressure-sensitive adhesive 18, 19 is applied to the inner surface of points 7 and 8 parallel to both side edges of the cut, except for the points 16 and 17 near the apex of the isosceles triangular cut. Is applied, and release papers 20 and 21 are releasably adhered to the application portion.

[0005]

[Action]

 At the apex of the isosceles triangular cut, the release agent 15 is applied to a portion corresponding to this portion, or the pressure sensitive adhesives 18 and 19 are not applied to the same portion. It is possible to use the apex of the isosceles triangular cut as a gripping piece.

[0006]

[Effect of device]

 Since the envelope according to the present invention is as described above, it has the remarkable effect of completely achieving the intended purpose of providing a new envelope that is sufficiently easy to open.

[0007]

【Example】

 In the first embodiment shown in FIGS. 1 to 3, a back side upper half plate 4 and a back side lower half plate 5 are provided on the upper and lower edges of the front side plate 1 via upper and lower bent portions 2 and 3 with paper. The constituent material is cut, and the lower back half plate 5 of this constituent material is folded over the lower side of the front side plate 1 at the lower bent portion 3 and the left and right side edges of the lower side half plate 5 and the front side plate 1 are mutually separated. It is fastened to form the bag portion 6 and the tip of the back upper half plate 4 is cut into an isosceles triangle shape, and the pressure-sensitive adhesive 9 is applied to the inner surface of the line points 7 and 8 parallel to both side edges of the cut. 10 is applied, release papers 11 and 12 are releasably adhered to the applied portion, and the back upper half plate 4 is folded over at the upper bending portion 2 on the outer surface of the back lower half plate 5. The release agent 15 is applied to the pressure-sensitive adhesives 9 and 10 where the parts 13 and 14 near the apex of the isosceles triangular cut adhere. It is obtained by application.

In the second embodiment shown in FIGS. 4 to 6, the back side lower half plate 5 made of the constituent material obtained in the same manner as the first embodiment is folded over the back side of the front side plate 1 at the lower bending portion 3. Also, the back side lower half plate 5 and the right and left side edges of the front side plate 1 are fixed to each other to form a bag portion 6, and the tip of the back side upper half plate 4 is cut into an isosceles triangle shape. Pressure-sensitive adhesives 18 and 19 are applied to the inner surfaces of the linear points 7 and 8 parallel to both side edges, except for the points 16 and 17 near the apex of the isosceles triangular cut, and are separated from this applied section. The paper patterns 20 and 21 are detachably attached.
