[Technical field to which the invention belongs]

[Prior art]

 Although science and technology have progressed in modern times, the exchange of letters has not and has not been discontinued since ancient times. Letters are now the most widespread and most economical means of communication. However, the envelopes we have used over the years have basically remained largely unchanged. However, there were only slight changes in the design, such as adding a window or making the folded surface longer or semicircular. In addition, the structure of the sealing opening can be improved simply by attaching a metal button and wrapping a cotton string around it, or pasting glue in advance to open the sealed envelope or bag. There was no ingenuity. Recently, an envelope was designed in which the cotton thread was fixed by applying glue on the folding line of the folded surface of the envelope, the end of the thread was slightly exposed from the corner of the envelope, and the thread was pulled up and opened. This method has the following obvious disadvantages. First, it is not easy to apply glue and cotton thread on the folding line of the envelope at the same time. Second, gluing and cotton threading operations are costly because they cannot be performed simultaneously on a machine. Thirdly, when pulling up the cotton thread, the phenomenon that the cotton thread and the folded surface are likely to be separated easily occurs, and the opening is failed. Fourth, if a cotton thread is exposed at the corner of the envelope, there is a risk that it will be accidentally opened during the mailing process.

[Problems to be solved by the invention]

 The main purpose of the present invention is to propose an envelope that can be easily opened.The envelope can be securely opened in both vertical and horizontal rectangular envelopes, is convenient in use, is easy to manufacture, and can be mailed. It has the characteristic that it will not be opened accidentally during the process.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the simple opening eco-envelope of the present invention mainly includes an envelope and an adhesive tape. A cutting line is provided on the folding line of one of the upper folding surface, the lower folding surface, the left folding surface, and the right folding surface of the envelope, and a strong adhesive tape having a width of about 2 to 3 mm is stuck on the cutting line. Attach Further, a cut line is obliquely formed at a corner of either end of the cut line. In use, break the beveled cut line and gently pull it up toward the other end, and the adhesive tape will detach from the cut line and open the envelope.

[0005]

[Embodiment of the invention]

 As shown in FIGS. 1, 2, 3, 4, and 5, the present invention mainly includes an envelope 1 and an adhesive tape 3. The envelope 1 has an upper folding surface 11, a lower folding surface 12, a left folding surface 13, and a right folding surface 14. There is a folding line between each of the folding surfaces and the envelope body 1, and the upper folding line 111 and the lower folding line 112 respectively. , Left turn line 113 and right turn line 114. When the present invention is applied to a horizontally long square envelope 1, one of the upper fold lines 111, the lower fold line 112, the left fold line 113, and the right fold line 114 is selected, and a cut line 2 is provided at the fold line. A tough adhesive tape 3 having a width of about 2 to 3 mm is stuck on the cutting line 2, and cut lines 41 and 42 are obliquely formed at either corner of the cutting line 2. When the upper bent surface 11, the lower bent surface 12, the left bent surface 13 or the right bent surface 14 are pasted together, the cut lines 41 and 42 overlap to form a cut line 4 and a triangular portion 5 which can be easily broken. . The adhesive tape 3 is folded in half and located at the inner edge of the upper bent surface 11, the lower bent surface 12, the left bent surface 13, or the right bent surface 14. In use, the triangular portion 5 is cut off by breaking the diagonal cut line 4 and the triangular portion 5 is lightly pulled up to the other end together with the adhesive tape 3 so that the triangular portion 5 is attached to the inner edge of the cutting line 2. While the strong adhesive tape 3 is detached from the cutting line 2, the envelope is opened along the cutting line 2 on the folding line 111, 112, 113 or 114 of the envelope 1. At this time, as shown in FIG. 5, the adhesive tape 3 is only properly attached to the paper of the fold lines 111, 112, 113 and 114 of the envelope 1 and is not completely bonded to the paper. Therefore, when the adhesive tape 3 is pulled up, the adhesive tape 3 naturally comes off from the cutting line 2. Regarding the cutting line 2 and the adhesive tape 3 stuck thereon, in the case of the horizontally long square envelope 1, one of the upper folding surface 11, the lower folding surface 12, the left folding surface 13 or the right folding surface 14 is selected. However, in the case of a vertical envelope, it is appropriate to install the envelope 1 on the upper folding surface 11 or the lower folding surface 12 as shown in FIG. In both the vertical envelope and the square envelope 1, there are advantages and disadvantages when the cutting line 2 is provided on the upper folding surface 11 and when the cutting line 2 is provided on the lower folding surface 12, respectively. When provided on the upper folding surface 11, the upper part of the envelope 1 is opened, which is convenient for a person who has the habit of opening the upper part of the envelope on a regular basis. Is troublesome to open. When the cutting line 2 is provided on the lower folding surface 12, the lower part of the envelope is opened, and even if the envelope is sealed with a staple, it can be easily opened.

[0006]

[Effect of the invention]

 The present invention can be reliably opened even in the case of a vertical envelope or a horizontally long square envelope, there is no fear of being opened by mistake during the mailing process, and it is convenient to use and easy to manufacture. This is a very practical envelope that is completely different from the conventional envelope opening method.
