Abstract

(57) [Summary] (Corrected) [Purpose] It should be possible to easily open the envelope without damaging the contents. [Structure] Insert perforations 1 and 2 and punch holes 3 and 4 in an elliptical shape. The hole 3 has such a size that when the hole 3 is folded along the fold line 5 and folded, the hole 3 fits into the triangle 9 formed by the vertices 6 to 8. The hole 4 has a size that does not protrude from the triangle 13 connecting the vertices 10 to 11. An envelope can be made by folding the folding line 14 into a mountain fold and folding the folding lines 15 to 17 into a valley fold.
When pasted with the glue margins 18 and 19, the triangles 9 and 13 are also glued through the holes 3 and 4. The envelope will be broken line 14
By pulling the knob portion 20 which can be folded into a mountain, the perforations 1 and 2 can be cut from the glued triangles 9 and 13 and opened. A notch 21 is provided to make it easy to grip the knob portion 20.

Description

[Detailed description of the device]

 The envelope of this invention is an envelope that can be opened with one touch without using scissors or the like and damaging the contents.

[Industrial applications]

 You can put a guide for each event

[And 0001] Envelopes that are widely used across genres in terms of novelty, convenience, and safety when used as a package in each shop.

[0002] The novelty of opening and its interestingness are used for greeting cards and the like.

[Prior Art]

 With conventional envelopes, the only option was to cut them with scissors, or to insert perforations around the envelope and open it manually.

[Problems to be solved by the device]

 If you open the envelope with scissors or by hand, the contents inside may be damaged. The envelope of the present invention can be taken out without damaging the contents inside by simply pulling.

[And 0003] It is a simple way to open the envelope so that even one person can use a guide that is often thrown away because of the difficulty of opening it.

[Means for Solving the Problems]

 On the right side of the envelope, a notch is made on the right side of the envelope, and there is a knob underneath. The knob is made from the back of the envelope by changing it in the middle of the envelope. There are perforations in the hidden portion of the envelope linked to the knobs, and there are margins on both outer sides of the perforations. Pulling the knobs cuts the perforations and the envelope can be opened easily.

[And 0004] The margins on both outer sides are made on the back side of the envelope so that the margins on the top and bottom of the envelope are attached at the same time as the glue is applied, making it easy to make envelope bags.

Claim 3. By making perforations in detail, the perforations can be cut cleanly to the end without tearing in the middle.

[Action]

FIG. 2 of 22. If you pull the part

[Fig.1] The perforation of 1.2 is cut and the envelope can be opened easily.

【Example】

 The following is a description based on examples.

FIG. 2 of 22. The knob part is connected to the margin with a piece of paper

FIG. 1. Is folded at the part

FIG. 1 1.2. With perforations

FIG. 1: 9.13. Depending on the margin of the part

FIG. 2 If you pull the part

[Fig.1] The perforation of 1.2 is cut and the envelope is opened.

[Figure 3] is the unsealed shape.

[Effect of the device]

 The envelope of the present invention can be easily opened by simply pulling it without damaging the contents. Since the act of opening the bag is simple, novel, and interesting, the number of guides that are thrown away without being unexpectedly troublesome will be reduced.

[0006] Due to the novelty of opening, it is used for greeting cards and the like.

Claims (3)

[Scope of utility model registration request] [Claim 1] Add perforations to 1.2 in the development view of [Fig. 1]. 3.
4 is an oval type and has a hole. 3. The hole of is a triangle formed at the apex of 6.7.8 when it is folded and folded along the polygonal line 5. It has a size that fits inside, and there is a hole in the position where it will never protrude. 4. The hole of 10.11.12. 13. A triangle connecting the vertices of It is the size of the hole that does not stick out, and it is pulled out in the position. Line with the above conditions promised 14. You can make an envelope by folding the folds into a mountain fold and the fold lines 15.16.17 into a valley fold. At this time, when pasting with margin 18.19 3.4. The 9.13 triangle is also glued through the hole. The envelope thus formed has a polygonal line 14.
You can make a mountain fold 20. By pulling on the knob part of 1.2. Perforated triangle 9.1 with glue
3. It is cut into pieces and can be opened easily. 20. 21. To make it easier to pinch the knob part of I made a notch in. The envelope constructed as above is the envelope of the present invention. 2. The method of 3.4. Of FIG. 9.1 by making a hole in the
3. 18.1 The work of applying the glue to the margin area
9. You can do this at the same time you paste. 3. FIG. 1 1.2. Insert the perforations as shown in [Fig. 1] so that they overlap each other. In that case 1. Perforations are 7.8. On the line connecting Up, 8. When you look down at 8. Starting from, insert from the second perforation so that it overlaps from the bottom of the first perforation. The third is from the lower part of the second, and the perforations are 7. 20. The force generated when pulling on the knob of the escape escapes to the bottom. The perforations that have been put in duplicate pick up and go to the next perforation, and the perforations continue in sequence. Prevents the paper from tearing in the middle of the perforation. Same principle 2. I will also add perforations.
This is 12. Up, 11. Insert the second perforation so that it overlaps from the upper part of the first perforation in order to bring the force to escape upward when looking down. In that sequence 11. Add perforations up to.
