Description

Envelope

Technical field

The present invention relates to an envelope sealed by a flap piece.

Akira Background technology

Generally, this type of envelope sealed by a flap piece includes a bag-shaped envelope body having an opening and a flap piece for closing the opening of the envelope body.

Such envelopes are sealed by storing letters and other items in the envelope body, folding back the flap pieces, attaching the flap pieces to one side of the envelope body, and closing the opening. Done. .,

On the other hand, the opening of such an envelope is performed by cutting the vicinity of the opening where the flap pieces are stuck.

To facilitate opening in such a case, an envelope as shown in FIG. 9 is also known. In the envelope shown in FIG. 9, two perforations 23, 23 are formed on both side edges 22 a, 22 a of the flap piece 22 in the width direction, and the inner surface of the flap piece 22 is formed from the perforation position. Also, the adhesive 24 is provided on the end portion 22b of the flap piece 22. Such an envelope 21 can seal the opening 26 by sticking the flap piece 22 to the outer surface of the envelope body 25 via the adhesive 24, while, when opening the envelope, the two perforations are used. By removing the cut portion 27 surrounded by 23 and 23 through the perforation 23, the flap piece 22 is cut and the envelope 21 can be opened.

However, since such an envelope is formed so that the perforations 23 reach the side edges 22a of the flap pieces 22, when the sealed envelope is mailed, for example, the side edges of the cutting portion 27 are used. When a trap occurs on 22a, the perforation 23 is inadvertently broken and The dividing portion 27 may be inadvertently twisted from the edge 22a.

In particular, recently, postal items are displayed on the envelope 21 with identification means such as a bar code, and are sorted by a machine using the identification means. While passing through the postal code sorting device, the flap piece 22 was cut off from the perforation 23 and the dividing portion 27 was rolled up, so that there was a problem that it was difficult to process a large amount and quickly with a mechanical sorting device. Disclosure of the invention

In view of the above, an object of the present invention is to provide an envelope that is not likely to be damaged by a mechanical device and that can be easily sealed and opened when used. It is.

In order to achieve such an object, the present invention relates to an envelope provided with a sealing flap piece 3 attached to an outer surface of an envelope body 2, wherein the envelope body 2 has a flap attached thereto. A perforation 5 is formed at a position substantially covered by the piece 3, and the perforation 5 provides an envelope formed along the end portion 3 b of the attached flap piece 3. Is what you do.

The envelope body 2 can be formed with a score line 7 for opening the opening, which is continuous with the perforation 5.

Also, the flap piece 3 can be formed in a shape that becomes gradually narrower toward the tip 3a, in which case the cut line 7 is formed at a position corresponding to the tip 3a of the flap piece 3. be able to.

Furthermore, a predetermined indication 14 can be given to at least an inner surface of the envelope body 2 with respect to an outer surface to which the flap piece 3 is attached.

As described above, since the envelope of the present invention has perforations formed in the envelope main body, it can be easily opened using the perforations when opening.

Further, at the time of sealing, such perforations are substantially covered by flap pieces. Therefore, when sorting large quantities of mail quickly using, for example, a mechanical sorting device, there is no inadvertent breakage at the perforations.

In addition, since the score line for the opening start point is formed continuously with the perforation, the opening force is smoothly transferred to the perforation by using the perforation at the time of opening, and along the perforation. The flap piece can be easily opened, particularly when the cut line is formed at a position corresponding to the tip of the flap piece having a gradually narrowing shape.

In addition, if a predetermined sign is given on at least the inner surface of the envelope body with respect to the outer surface to which the flap piece is attached, after opening, the specified part is located on the most visible part of the inside of the flap piece. Since the display is made, the display can be shown to the user in an easily viewable state. BRIEF DESCRIPTION OF THE FIGURES

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

As shown in FIGS. 1 to 3, the envelope 1 is attached to an envelope body 2 and an outer surface of the envelope body 2. And a flap piece 3 to be worn.

The envelope body 2 is formed, for example, in a substantially rectangular bag shape in which two sheet materials are overlapped and an opening 4 is provided on one long side.

The flap piece 3 is a piece that extends from one sheet material of the envelope body 2 via the folded line 6, and has a front end portion 3 a, for example, a substantially isosceles triangular front shape as shown in FIG. 1. Is formed in a shape that becomes narrower in accordance with the above.

The sheet material is made of a material that can be cut, and for example, a known material such as paper, a synthetic resin film, or a nonwoven fabric can be used.

On the outer surface of the envelope body 2 on the side to which the flap pieces 3 are attached, as shown in FIG. 3, an opening sewing machine that draws a line parallel to the line of the end portion 3b of the flap pieces 3 at the time of sealing. Eye 5 is formed.

The perforation 5 is located at a position where the flap piece 3 is practically covered and covered by the flap piece 3 when the flap piece 3 is adhered. It is provided so as to be located immediately outside.

Further, the envelope body 2 is formed with a cut line 7 that is continuous with the perforation 5, and a tongue portion 8 surrounded by the cut line 7 and serving as an opening start point.

As shown in FIG. 3, when the flap piece 3 is stuck, the tongue-shaped portion 8 is not covered by the tip portion 3a of the flap piece 3, but is located outside the cut line 7 as shown in FIG. It is formed in.

When the flap piece 3 is folded back toward the envelope body 2 on the inner surface of the flap piece 3, an adhesive portion 10 is provided at a portion corresponding to the sticking scheduled portion 2 a of the envelope body 2. The adhesive portion 10 is made of a re-wet glue that produces an adhesive force when wet. Note that the adhesive portion 10 may be, for example, one formed by providing release paper or the like on the surface of the adhesive, or another member.

Further, on the inner surface of the envelope body 2, an arbitrary display 14 such as a product advertisement and various notices is provided by a known means such as printing or labeling. This arbitrary indication is given at least on the inner surface of the envelope body 2 with respect to the outer surface to which the flap pieces 3 are attached.

In addition, if necessary, the envelope body 2 may be provided with a window for visually confirming a stored object such as a stored letter from the outside. Further, in order to enable sorting by the sorting device, an identification means such as a bar code may be displayed on the outer surface of the envelope main body 2 or on a stored item. However, when this is displayed on the stored item, the identification means is displayed on the part visible from the window.

When using the envelope 1 configured as described above, the adhesive 10 of the flap piece 3 is wetted to generate an adhesive force, the flap piece 3 is bent at the folding line 6, and attached to the outer surface of the envelope body 2. By the attachment, the adhesive portion 10 is adhered to the sticking portion 2a of the envelope body 2 and sealed.

As shown in FIG. 3, the perforated line 5 of the envelope 1 thus sealed is substantially coincident with the end portion 3b of the flap piece 3, so that the perforated line 5 is substantially formed by the flap piece 3. Therefore, at the time of mailing, there is no possibility that the portion where the perforation 5 is formed is caught by something, and there is no possibility that the perforation 5 may be inadvertently broken. Therefore, when sorting mail, passing through a mechanical sorting device does not cause any trouble.

Next, when opening the tongue, the tongue 8 surrounded by the cut line 7 protruding outward from the tip 3a of the attached flap piece 3 is picked, and the tongue 8 is used as a starting point. By pulling up the flap piece 3, as shown in FIG. 4, the flap piece 3 and the sticking surface of the envelope body 2 stuck to the flap piece 3 are cut off along the perforations 5.

Thus, the envelope 1 can be easily opened via the perforations 5.

In particular, the flap piece 3 is formed in a narrower shape toward the tip 3a, and a score line 7 for opening the opening is formed at a position corresponding to the tip 3a. Since the perforation 5 is formed parallel to the line of the end 3b of the piece 3, when the flapper piece 3 is pulled up, the envelope body 2 is reliably cut off according to the perforation 5. Becomes

After opening, a predetermined indication 14 is provided on the inner surface of the envelope main body 2 cut out together with the flap piece 3. Can be seen, and the effect of advertising is enhanced.

In the above-described embodiment, the envelope body 2 is formed in a substantially rectangular shape on the front, but may be formed in a substantially square shape on the front, for example. Further, the size of the envelope body 2 is not limited to a fixed size, and may be a size other than the fixed size.

Further, in the above embodiment, the flap piece 3 is provided on one long side of the envelope body 2, but for example, as shown in FIG. 5, the flap piece 3 is provided on one short side of the envelope body 2. Although not particularly shown, the flap pieces 3 may be provided at two or more locations.

Further, in the above-described embodiment, the shape of the flap piece 3 that becomes gradually narrower toward the distal end portion 3a is formed in a substantially isosceles triangle shape on the front side, but it is formed in a triangle shape other than the substantially isosceles triangle shape. It may be formed, and is not limited to a triangular shape. For example, as shown in FIG.

In this way, by forming the flap piece 3 into a shape that gradually becomes narrower toward the tip 3a, there is an advantage that the flap piece 3 can be reliably cut off along the perforation 5 and can be easily opened. As shown in FIG. 7, the end portion 3b may be a flap piece 3 formed in a straight line.

In the above-described embodiment, the perforation 5 is formed along the flap piece 3 in such a manner that the perforation 5 is formed in parallel with the end portion 3b of the flap piece 3. The form formed along the piece 3 is not limited to this, and for example, as shown in FIG. 6, the shape of the line of the perforation 5 may be formed in a shape different from the shape of the end portion 3b of the flap piece 3 .

Further, in the above embodiment, the perforations 5 are formed immediately outside the intended attachment portion 2a, but the perforations 5 are necessarily formed immediately outside the intended adhesion portion 2a. Although not particularly shown, it may be formed, for example, between the end portion 3b of the flap piece 3 to which the perforation 5 is attached and the portion 2a to be attached to the flap piece 3. As shown in FIG. 8, the perforations 5 may be formed so as to straddle the portion to be stuck 2a. Also, not all perforations 5 need to be covered with the flap pieces 5, and some of the holes that make up the perforations 5 are located at positions where they are not covered by the attached flap pieces 3. That is, it may be provided so as to protrude outside the flap piece 3 that is stuck.

In short, the perforations 5 may be formed so as to be substantially covered by the attached flap pieces 3 so as not to be broken carelessly.

Further, the perforation 5 defined in the present invention means a means in which the part where the perforation is formed is more easily broken than other parts, that is, the perforation is more likely to be cut. Not only does it mean a continuous gathering of holes and non-holes as in the case of the seam, but also includes, for example, a configuration in which a part of the envelope body 2 is weakened. Furthermore, in the above embodiment, the opening score 7 is provided at a position corresponding to the leading end 3a of the flap piece 3, that is, at the center position of the trailing end 3b. Ί does not necessarily have to be provided at a position corresponding to the tip 3a of the flap piece 3, and may be provided at a position corresponding to the side edge 22a of the flap piece 3, for example. Can be changed to

Further, in the present invention, this type of cut line 7 does not necessarily have to be formed, and as shown in FIG. 5, the cut line 7 may not be formed. Further, in the above embodiment, the adhesive portion 10 is provided on the flap piece 3. However, for example, the adhesive portion 10 may be provided on the portion 2 a to be attached of the envelope body 2, and the flap piece 3 and the envelope body 2 may be provided. In any of the above, the adhesive portion 10 may not be provided.

In the present invention, the portion 2a to be attached refers to a conceptual area for attaching a bonding agent for attaching the flap piece 3 to the envelope body 2, that is, a so-called "paste margin". 2 may have some indication indicating the intended sticking part 2a, The indication need not be made.

In addition, the use of the envelope 1 according to the present invention is not limited to postal use, but can also be used for various kinds of portable envelopes and storage envelopes of stored items such as documents and articles.
