Abstract

(57) [Summary] [Purpose] It is intended to provide a double-opened envelope that can be easily opened with fingers on either the upper side or the lower side of the envelope, and can be reasonably resealed after being opened once. [Structure] A left and right adhesive rupture zone 8 for forming an outer surface adhesive layer 7 divided by rupture lines 6 such as perforations is provided on both left and right sides sandwiching a central upper end 3a of an upper end of a backing paper 3 which constitutes an envelope 1. 5 is provided corresponding to the left and right adhered parts, and a breaking line 9 for opening the lower part is provided at the lower end of the envelope 1. When the lid 5 is opened after the adhesive sealing, the left and right adhesive breaking zone 8 is bonded to the lid 5 side and broken. It will be separated. [Effect] The most effective and stable sealing can be achieved by the minimum contact adhesion of the lid. In addition, even after opening once, the lid can be easily and reasonably resealed by pressing the central portion of the lid with the central upper end of the backing paper. Further, this envelope can be opened on either the upper side or the lower side, and has a simple structure and is inexpensive.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double-opened envelope, and more particularly to a double-opened envelope that can be easily opened with fingers on either the upper or lower side of the envelope and that can be used again after being opened once.

[0002]

[Prior art]

 In recent years, various envelopes that can be easily sealed and opened have been considered, but for example, the structure is complicated due to being restricted only by the certainty of sealing and opening, which in turn causes inconvenience and high cost in use. There were merits and demerits, etc., and there was nothing suitable.

[0003]

[Problems to be solved by the device]

 Therefore, there is a demand for novel ideas such that the envelope can be reused and reused even after it has been opened once, but in the end it was sealed by a troublesome adhesive paste and opened with scissors and a knife such as a knife. You are forced to rely on the means.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and is configured as follows.

That is, the double-open envelope of the present invention is a left and right adhesive rupture zone for forming an outer surface adhesive layer that is divided by rupture lines such as perforations on both left and right sides sandwiching the center upper end of the upper end of the backing paper that constitutes the envelope. Is provided corresponding to the left and right adherends of the lid, and a breaking line for opening the lower part is provided at the lower end of the envelope.When the lid is opened after adhesive sealing, the left and right adhesive fracture zones are attached to the lid side and fractured and separated. It will be like this. Next, the present invention will be described in detail with reference to the following embodiments with reference to the drawings.

[0006]

【Example】

 First, 1 is an envelope composed of a cover 2, a back 3 and a bottom 4 having a lid 5 on the upper end. Therefore, in the present invention, the left and right adhesive fracture zones of the outer surface adhesive layer 7 formed by the perforation lines 6 such as perforations on both the left and right sides sandwiching the central upper end 3a of the upper end of the backing paper 3 which constitutes the envelope 1 are defined. 8 and 8 are provided corresponding to the left and right adherends of the lid 5, respectively. Then, after the lid 5 is sealed and sealed to the outer adhesive layer 7, the left and right adhesive break zones 8 and 8 are bonded to the lid 5 side and broken and separated by opening the lid 5. A break line 9 such as a perforation for opening the lower portion is provided at the lower end of the envelope 1.

Then, first, a letter is put in the envelope 1 of FIG. 1, the lid 5 is bent, and pressed against the left and right adhesive rupture zones 8 and 8 of the backing paper 3 to attach the lid 5 to the left and right outer surface adhesive layers 7 and 7. Seal them as shown in Fig. 2 by contact bonding. Next, in FIG. 2, when the lid 5 of the envelope 1 is flipped with a finger in the direction of the arrow, the perforation break lines 6 and 6 of the left and right adhesive break zones 8 and 8 are broken, respectively, and the envelope can be opened as shown in FIG. At this time, as shown in FIG. 3, the left and right adhesive rupture zones 8 and 8 which are ruptured are adhesively separated on the lid 5 side, and at the upper end of the backing paper 3, left and right rupture concave portions 8a and 8a are formed by rupture separation. Formed respectively. Therefore, after opening as shown in FIG. 3, another letter can be put in the envelope 1, and the lid 5 can be sealed by pressing the central portion of the lid 5 with the central upper end portion 3a of the backing paper 3 as shown in FIG. It is a thing.

[0008]

[Effect of device]

 As described above, the envelope of the present invention has the minimum outer adhesive layer at the two left and right sides by pressing both the left and right sides of the lid against the left and right adhesive break zones of the backing paper when initially sealing. The most stable and effective sealing can be achieved by the contact adhesion of. In particular, in the case of the envelope of the present invention, after sealing as described above, when the lid is flipped over, the perforation break lines are broken respectively, and the left and right adhesive break zones are each adhesively separated, and the lid can be easily opened and the backing paper Since the upper end of the center is formed with the center upper end and the left and right break recesses on both sides sandwiching it, for example, even after opening once as described above, for example, put the lid on the center part of the center top of the backing paper. It can be easily and reasonably resealed by holding it between the parts. Further, this envelope can be selectively opened on either side of the upper and lower edges thereof or opened on both sides as needed, and the structure is simple and can be provided at low cost.
