Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an envelope provided with perforations that are easy and reliable to seal and open.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, an envelope of this type includes an envelope body 11 and a flap portion 12 integrated with the envelope body 11 via a folding line. An envelope provided with perforations 13 has been proposed. In such an envelope, two perforations 13 are formed in the flap portion 12 that closes the opening formed in the upper end of the envelope body 11. Then, it was folded back at a center line located in the middle of these perforations 13 and sealed so that the perforations 13 overlap each other. At the time of opening the envelope, one of the left and right corners 14 at the upper end of the envelope was picked to open the envelope along the perforations 13.

[0003]

[Problems to be solved by the device]

 However, in such a conventional envelope, it is not easy to cut it with a fingertip along the perforations 13 in the overlapping portion of the front side and the back side of the envelope. Therefore, in some cases, tools such as scissors and paper knives must be used, and it was difficult to open them with a single touch. In particular, it was very difficult to open the envelope when the paper sheets were thick or the perforations 13 did not exactly overlap each other. Then, if the bag is forcibly opened, the cut line may be misaligned from the perforation 13 and may fail, and in extreme cases, the contents such as notepaper may be damaged.

In view of the above, the present invention eliminates the above-mentioned disadvantages of the conventional envelopes, can be easily glued at the time of sealing, and can be easily opened with one touch without using tools such as scissors. Even if the contents are put all over the envelope, it is possible to open the contents without damaging the contents, and once opened, it is impossible to seal the contents again by gluing etc. The purpose is to provide a useful envelope from the viewpoint of holding.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, there is obtained an envelope in which a plurality of perforations are formed in parallel with a certain width for peeling on a flap portion that closes an opening formed at the upper end of the envelope body. To be Further, an envelope is obtained in which the plurality of perforations have a cut line at both ends thereof. Furthermore, an envelope is obtained in which peeling tabs tongues are formed to project from both ends of the plurality of perforations. Further, of the plurality of perforations, an adhesive is applied in advance to a region from the perforations located toward the bottom of the envelope in the folded back and sealed state to the edge of the flap portion. Is obtained. Furthermore, in a state where the upper edge of the back side of the envelope body is folded back and sealed, an envelope is formed which is lower than the upper edge of the front side and is positioned below the folding line.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(Embodiment 1) FIGS. 1 and 2 show a horizontal oblong so-called Western envelope according to an embodiment of the present invention. In the drawings, an opening for taking in and out a notepaper and the like (not shown) is formed at the upper end of an envelope body 1. Has been done. A fold line 2 is formed on the envelope body 1, and a flap portion 3 is integrally formed on the envelope body 1 via the fold line 2. When peeling, the strip-shaped peeled portion of the flap portion 3 has two perforations 4 and 5 arranged in parallel with each other with a sufficient spacing to obtain a strength that is not too thin and cannot be cut. Are formed respectively. And notches 4a and 5b for picking are formed at both ends of these perforations 4 and 5, respectively. In the figure, reference numeral 1a is a gap formed on the back side of the envelope so that contents such as notepaper can be easily taken out when opening.

[0008] The envelope thus configured is sealed and unsealed in the following manner. First, when the sender seals, the adhesive 6 such as glue is applied only to the tip of the flap 3 in the state shown in FIG. After that, the entire flap portion 3 is folded back inside out along the folding line, and the adhesive 6 is sealed so as to adhere to the back surface of the envelope body 1. The adhesive 6 may be applied by spreading the entire flap portion 3 as shown in FIG. 1, but by applying the adhesive margin portion to the front side along the perforations 4 or 5. Then, there is an advantage that it can be surely applied only to the margin portion.

When the recipient opens the bag, the end of the flap 3 between the cuts 4a and 5b at both ends of the perforations 4 and 5 is pinched with a fingertip and pulled laterally. When stretched, the flap portion 3 between these perforations 4 and 5 is easily peeled off in a striped pattern to open the envelope. That is, the flap portion 3 between the perforations 4 and 5 to be peeled off is not a double layer as in the conventional example of FIG. 5, but a single layer, so that it can be easily opened without a single-touch failure.

(Embodiment 2) FIGS. 3 and 4 show another embodiment of the present invention. In the drawings, the difference from the above embodiment is that the sewing machine replaces the cut lines 4a and 5b in FIGS. Tongue pieces 7a and 7b protruding laterally are formed at both ends of the eyes 4 and 5, respectively. Also in this embodiment, it is possible to close and open the envelope by the same operation as that of the above embodiment.

In all of the above-mentioned examples, the adhesive 6 such as glue was applied at the time of sealing. However, it is applied at the time of manufacturing the envelope and a seal is attached in advance, and the seal is peeled off at the time of sealing. It is also possible. In addition, although a horizontal oblong envelope has been described in the above embodiment, it is needless to say that the present invention can be similarly applied to a vertical Japanese envelope. Furthermore, in each of the above-mentioned embodiments, the cuts 4a and 5b or the tongues 7a and 7b for picking are formed at both ends of the perforation, but these may be formed on only one of the left and right sides.

[0012]

[Effect of device]

 It is easy to glue when sealing and can be opened easily without using scissors and other tools, and even if the entire contents of the envelope are filled, it can be opened again and once opened, it can be closed again. It is possible to provide an envelope that cannot.
