Example 1 (see FIGS. 1 to 5) In Example 1 shown in FIGS. 1 to 5, an end 3a of a thin plastic wire 3 using a fishing line on the upper surface of a triangular double-sided adhesive piece 4.
And press the upper pressing paper 4d of red surface color from above to fix the end 3a to the double-sided adhesive piece 4. The adhesive surface on the lower surface of the double-sided adhesive piece is attached to the corner of the upper side of the envelope body 1 where the opening is provided. The thin wire 3 is an example of a structure in which a corner portion from the inner fold line 2a of the sealing piece 2 is folded back to the front surface of the envelope body 1 and fixed by the double-sided adhesive piece 4b. Further, in the first embodiment, perforations 6 are provided along the inner fold line 2a. In the figure, F1 is the envelope of the first embodiment, 1 is the envelope body opened upward, 1a is the opening on the upper side of the envelope body, and 2 is integrally connected to the upper side of the envelope body 1 sealing the opening. Sealing piece, 2a is an inner bent line of the sealing piece, 3 is a thin plastic wire, 3a is an end of the thin wire, 4 is a right-angled triangular double-sided adhesive piece, 4a is an upper adhesive surface of the double-sided adhesive piece, 4b
Is a double-sided adhesive piece main body, 4c is a lower adhesive surface, 4d is a red upper pressing paper, 4e is a lower release paper, 5 is a perforation, and 6 is a perforation provided along the inner fold line 2a.

In the first embodiment, as shown in FIG. 5, an end 3a of a thin plastic wire 3 slightly longer than the length of the side of the opening 1a of the envelope F1 is attached to the upper adhesive surface 4a of the double-sided adhesive piece 4. An upper pressing paper 4d having a red upper surface is adhered from above to fix the end 3a. Then, the lower release paper 4e
Then, the double-sided pressure-sensitive adhesive sheet 4 is adhered to the upper side corner of the front side of the envelope body 1 using the lower pressure-sensitive adhesive surface 4c. One end 3
When a is fixed using the double-sided adhesive piece 4, the thin wire 3 is turned and stretched along the inner bending line 2a of the sealing piece 3,
The end is turned to the upper side corner of the front side of the envelope body 1 and pulled out, and is fixed with the double-sided adhesive piece 4 as described above.
A perforation 5 is formed symmetrically with the perforation 5 and the sealing piece 2 along the oblique side of the right-angled triangular double-sided adhesive piece 4 at the upper side corner of the envelope body 1. A perforation 6 is provided along the inner fold line 2 a of the sealing piece 3. Example 1
When the envelope F1 is opened in the above, the triangular area of the double-sided adhesive piece 4 at the upper side corner of the envelope body 1 is pinched with a finger,
When the triangular area which is broken along the perforation 5 and cut off as it is is lifted above the opening 1a, the thin line 3 hits the end of the inner bending line 2a of the sealing piece 2 from the horizontal, and the direction is changed. To bend the inner bent line 2
A concentrated load is applied to the turning point a, and the turning point is cut.
The inside bent line 2a is sequentially cut from the cut side by moving the cut triangular area toward another corner while pulling up. In this cutting, the perforation 6 is provided along the inner fold line 2a, so that the thin line 3 can be easily cut along the inner fold line 2a. Thus, the envelope F1 of the first embodiment can be easily and quickly opened with a finger. The triangular area to be pinched and cut has a red upper pressing paper 4d so that the position of the pinch can be accurately and correctly made.

Embodiment 2 (see FIGS. 6 and 7) In an envelope F2 of Embodiment 2 shown in FIGS. 6 and 7, the lower surface of a rhombus-shaped red pressing piece 20 is an adhesive surface 20a, and the envelope is formed by the adhesive surface. This is an example in which pressing pieces 20 are adhered to the left and right corners of the main body 1 and the sealing piece 2, and the fine wire 3 is fixed to the upper corner so as to be sandwiched between the envelope body 1 and the pressing piece 20. In this example, the end 3a of the thin wire 3 is pulled out from the inside bent line 2a of the sealing piece 2 and turned to be placed on the upper front side corner of the envelope body 1, and the pressing piece 20 is put thereon, The holding piece 20 and the end 3a of the fine wire are adhered and fixed on the surface 20a. Example 2
The envelope F2 is also folded in the same manner as in the first embodiment, and is folded back, and the pressing piece 20 that looks triangular is pinched by a finger, cut from the perforation 5, and moved to another corner while being pulled up. Then, the inner bent line 2a of the sealing piece 2 is cut by the thin wire 3 and opened. Also in this embodiment, since the perforations 6 are provided along the inner fold line 2a, it can be easily cut with a thin line. In the second embodiment, the structure is simple, and the pressing piece 20 straddles the envelope body 1 and the sealing piece 2, so that the pressing piece 20 is hard to be broken, and the separation from the perforation 5 can be reliably performed. Others are the same as the first embodiment.

Embodiment 3 (see FIGS. 8 to 10) The envelope F3 of Embodiment 3 shown in FIGS. 8 to 10 is a small folded triangular holding piece 30, and an upper surface 30a of the holding piece 30.
An adhesive 30c is applied to the inside of the lower surface 30b, and the end 3a of the thin wire 3 is sandwiched between the upper surface 30a and the lower surface 30b to join the upper surface 30a, the lower surface 30b, and the end 3a therebetween. This is an example in which the joined holding pieces 30 are attached to the upper edge of the envelope body 1 with the adhesive layer 30d on the front side of the lower surface 30b. Perforations 6 are provided intermittently along the inner bending line 2a. Other structures, functions, effects, and usage are the same as those of the above-described embodiment.

Embodiment 4 (see FIG. 11) In the envelope F4 of the embodiment shown in FIG. 11, the end of the thin wire 3 is folded back at the left and right ends, and the adhesive 41 is formed at the upper right and left corners of the envelope body 1 on the front side. This is an example of directly fastening with. The triangular area defined by the perforations 5 is printed in red. A cut 40 is provided along the inner fold line 2a. Since the thin wire 3 is fixed directly to the envelope body 1, the structure is the same as that of the above embodiment except that the structure is simple and the manufacturing cost is low.

[0012]

As described above, according to the present invention, the fine wire is stretched freely only along the fold line of the sealing piece, so that it can be attached accurately along the fold line, and Since the thin line largely changes the direction at the end, cutting along the fold line by the thin line can be performed reliably and easily, and beautiful and clean cutting is enabled. In the case where perforations or cuts are provided along the fold line, cutting with a thin line can be performed very easily and reliably.
