  In order to achieve the above object, an envelope of the present invention includes a bag-shaped main body having an opening formed on at least one side, a lid piece extending from the bag-shaped main body to seal the opening, and the opening A crease formed at the boundary between the bag-shaped main body and the lid piece, a linear member attached along a valley of the crease, and substantially at the center of the crease The bag-shaped body is formed so as to be separable, and includes a cutting region configured to cover the lid piece.

  Here, it is formed so as to be separable in the approximate center of the crease part, and is formed so as to be separable in the approximate center of the crease part by a cutting region that is configured to cover the bag-like main body and the lid piece, so that it is well balanced. Finger force can be applied to the ablation area.

  In the envelope of the present invention, it is preferable that a perforation and a slit are formed at the boundary line between the bag-shaped main body and the excision region and the boundary line between the lid piece and the excision region.

  In the envelope of the present invention, the slit is preferably formed at a position farthest from the fold portion.

  Further, in the envelope of the present invention, when the excision region is substantially circular, it matches the roundness of the fingertip, and the fingertip force can be applied to the excision region evenly.

  In the envelope of the present invention, the linear member is preferably a thread.

  The envelope which concerns on this invention is easy to cut | disconnect a cutting | disconnection area | region.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention.
FIG. 1 is a schematic rear view illustrating an example of the envelope of the present invention, and FIG. 2 is a schematic front view illustrating an example of the envelope of the present invention. In the drawings, the same reference numerals indicate the same members.
An envelope 1 according to the present invention includes a bag-like main body 2 in which an opening 3 is formed on at least one side and a mail or the like is placed, a lid piece 4 that extends from the bag-like main body 2 and seals the opening 3, and an opening 3 and a fold portion 5 formed at the boundary between the bag-like main body 2 and the lid piece 4, and a cotton thread (an example of a linear member) attached along a valley of the fold portion 5 6), a substantially circular excision region 7 formed so as to be separable in the approximate center of the crease portion 5 and extending over the bag-like main body 2 and the lid piece 4, and the bag-like main body 2 and the lid. An adhesive tape 10 attached to the lid piece 4 for bonding the piece 4 and a release paper 11 attached on the adhesive tape 10 for protecting the adhesive tape 10 are provided.

A perforation 8 and a slit 9 are formed at the boundary line between the bag-shaped main body 2 and the excision region 7 and at the boundary line between the lid piece 4 and the excision region 7.
The slit 9 is formed at a position farthest from the crease portion 5.
Further, the area of the excision region 7 extending over the bag-like body 2 and the area of the excision region 7 extending over the lid piece 4 are substantially the same.

  Further, the fold portion 5 of the envelope 1 of the present invention shown in FIGS. 1 and 2 is not formed with perforations or the like, but the crease portion 5 has a perforation so that it can be smoothly cut by the thread 6. Etc. are preferably formed.

  Moreover, since the cotton thread is used as the linear member, it is easy to attach glue and is environmentally friendly.

  In addition, the envelope of the present invention has a bag-shaped main body having an opening formed on at least one side, a lid piece extending from the bag-shaped main body to seal the opening, and a configuration along the opening and the bag-shaped main body A crease formed at the boundary between the cover and the lid piece, a linear member attached along the valley of the crease, and formed to be separable substantially at the center of the crease. The envelope of the present invention does not necessarily include an adhesive tape, but an adhesive tape is preferable because it can be easily sealed.

  In addition, the envelope of the present invention has a bag-shaped main body having an opening formed on at least one side, a lid piece extending from the bag-shaped main body to seal the opening, and a configuration along the opening and the bag-shaped main body A crease formed at the boundary between the cover and the lid piece, a linear member attached along the valley of the crease, and formed to be separable substantially at the center of the crease. The ablation region is not necessarily substantially circular, for example, it may be a triangle or a quadrangle, but if it is substantially circular, it matches the roundness of the fingertip. In addition, it is preferable because the force of the fingertip can be uniformly applied to the ablation region.

  In addition, the envelope of the present invention has a bag-shaped main body having an opening formed on at least one side, a lid piece extending from the bag-shaped main body to seal the opening, and a configuration along the opening and the bag-shaped main body A crease formed at the boundary between the cover and the lid piece, a linear member attached along the valley of the crease, and formed to be separable substantially at the center of the crease. 2 types of perforations and slits are not necessarily formed on the boundary line between the bag-shaped main body and the excision region and the boundary line between the lid piece and the excision region. For example, only perforations or only slits may be formed.

FIG. 3 is a schematic view for explaining the opening procedure of the envelope of the present invention.
As shown in FIG. 3A, the excision region 7 is picked with a finger, and the excision region 7 is pushed to the front side or the back side of the envelope 1, whereby the excision region 7 is removed from the envelope 1 along the perforation 8 and the slit 9. Disconnected.
Next, as shown in FIG. 3 (b), the cut region 7 is pulled upward, whereby the thread 6 is also pulled, and the fold portion of the envelope 1 is cut by the thread 6 pulled upward.
Then, as shown in FIG. 3C, all the folds are cut, one side where the opening of the envelope 1 is formed is opened, and the postal matter 12 is taken out from the envelope 1.

  As described above, since the envelope of the present invention includes a resection area formed so as to be separable at the approximate center of the fold portion, it is possible to apply finger force to the resection area in a balanced manner, and thus the envelope is square. Even if it is a big thing like No. 2 or it is a western envelope, it is easy to cut | disconnect an excision area | region and can open it easily by hand.

  In addition, since the ablation area is substantially circular, it matches the roundness of the fingertip, and the force of the fingertip can be applied uniformly to the ablation area, making it easier to separate the ablation area.

It is a schematic rear view explaining an example of the envelope of this invention. It is a schematic front view explaining an example of the envelope of this invention. It is the schematic explaining the opening procedure of the envelope of this invention. It is the schematic explaining an example of the conventional envelope.
