Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous wide-mouth postal envelope in which postal envelopes each having a wide-mouth opening at the top are vertically connected via a sealing portion in an open state.

Conventional continuous envelopes such as sealed envelopes, horizontal envelopes, and hollow envelopes are all sealed on all sides or have openings oriented perpendicular to the flow direction. Vertical envelopes with an opening at the top are known, but it is necessary to separate the overlapping piece facing the sealing part in the same way as the upper paper piece and the lower paper piece during use, and in a continuous state, it is not possible to open the envelope. do not have. In addition, after the envelope is formed, the fold line of the sealing part coincides with the upper edge of the bottom paper piece, so the thickness of the bottom paper piece,
Movement of inclusions2. Due to external impact during mailing, the above fold line t
There were also incidents where confidentiality could not be maintained due to rifts.

On the other hand, there is a known method of separating and pasting an address label with the address stamped out using a line printer (=j) on the normal sealing part and the wart sealing part, but it involves many steps and is time-consuming.
Also, a dedicated processing machine was required.

An object of the present invention is to provide a continuous wide-mouth mail envelope that has a wide opening in the machine direction in a continuous state and can be turned into a regular envelope by simply tearing it apart, and can print directly on the surface of the envelope.

In the continuous wide-mouth mail envelope of the present invention, both side edges are used as feed holes, and a cut-off perforation line is provided along the inner side edge, and the cut-off perforation line is separated from the top paper part of the envelope and the sealing part connected to the top side. Both sides of the sealing part and the upper paper part of the envelope are configured as a vertically connected body of unit upper paper pieces connected to the feed hole part through the above-mentioned cutting perforation line, and the upper paper pieces are separated at the joints of the unit upper paper pieces. L: L line is provided, and the sealing part has a long sheet of paper with a fold line parallel to the upper side of the lower paper part of the envelope, and a long sheet of paper having the same width as the long sheet of paper, and a line on both sides. A cut-off perforation line is provided along the inner side edge of the feed hole, and during the cut-off perforation, the lower paper part of the envelope, which has the same dimensions as the upper paper part of the envelope, is punched out by the punching part to correspond to the sealing part of the upper paper piece. and a long sheet of paper connected to the feed hole section through the separation perforation at both side edges with an interval of This is a continuous envelope in which the envelope and the lower paper part of the envelope are attached to each other at the six edges of both sides and the bottom, and an adhesive layer is provided along the upper edge of the sealing part.

The continuous wide-mouth mail section M of the present invention will be explained below from the drawings.

The long paper 1 is provided with feed holes 6 along both side edges,
Each unit top paper piece consists of an envelope top paper part 5 and a sealing part 6 connected to its upper edge via a fold line 12, and each unit top paper piece is separated from each other and connected vertically via a perforation line 7. Both side lines of the unit paper piece are connected to the feed hole portion 6 via the separation perforation line 4.

The long paper 2 has the same width as the long paper 1, and both 1
1111 A feed hole portion 6 is provided along the sacrum edge, and the lower envelope paper 7SII 8 iJ-Envelope- has a width M smaller than the paper portion 5. The upper edge of the lower paper piece is connected to the sealing portion 6 and the envelope. Upper and lower paper parts 5.8/f: sum of the width difference (this is punched out at corresponding intervals to form the punched parts 9, and the sprouted side line parts are separated and passed through the center line 4 to the feed hole part 6 Connect it to .

The middle lower paper pieces are connected in the vertical direction through the feed holes 6 on both side edges.

The long papers 1 and 2 are collated by the feed hole part 3, and the upper paper part 5 and the lower paper part 8 of the envelope are superposed, and the adhesive layer 10 is formed.
? From this, the six side edges and the bottom edge are in contact with each other.

The adhesive layer can be provided on either or both of the upper paper part and the lower paper part of the envelope.
In the case where an adhesive layer is provided on the envelope, when forming the punched portion 9 described above, it can be punched out together with the excess adhesive on the lower side, and other envelopes to which the excess adhesive is connected can be punched out. This provides the advantage of preventing the accident of adhesion to the inner surface of the sealing part 6 of the upper paper piece 5.

A suitable adhesive 11 is applied to the upper edge of the sealing part 5, and the lower edge connected to the upper edge of the upper paper part 5 of the envelope is marked with a crease line or a rough line (by perforating the fold line 12 of the envelope). The fold line 12 is provided parallel to the frontage b.This fold line 12 is formed by folding back the sealing part 6 and forming the upper edge part ζ of the envelope lower sheet iSB 8.
This is provided at a predetermined position where it can be adhesively sealed. The sealing portion may be set to be larger than at least the difference in vertical width between the upper and lower paper portions 5 and 8 of the envelope.

The adhesive layer 11 of the sealing part can be formed using a rewettable, self-adhesive or pressure-sensitive adhesive, or a double-sided tape.
When a self-adhesive adhesive is used, an adhesive layer 13 is provided at a position corresponding to the upper edge of the lower paper portion of the envelope, as shown in FIG.

The sealing section 6 can also have its upper corner 14 cut off by punching out the long sheet 1 or before or after the unit envelope is separated, if desired.

The continuous wide-mouth mail envelope of the present invention can be used as a normal wide-mouth envelope by separating it and removing the perforation 6 along perforations 4 and RIQ into unit envelopes (FIG. 3).

In the continuous wide-mouth mail envelope of the present invention, the unit envelopes are connected through the sealing section, so although it has 10 openings that open in the sending and receiving direction, it does not jam in the printer in a continuous state, and it can be re-attached to the sealing section. It was also found that applying the wet adhesive did not cause any problems to the printer. Therefore, the address can be printed directly from the printer using the business form, and there is no need to affix a separate address label with the address printed on it, unlike conventional products, simplifying the process.

Adhesive is applied to the sealing part, and the upper edge of the unit paper piece facing it is punched out, so there is no need to worry about blocking even when continuous envelopes are folded in a zigzag pattern. This can be completely prevented, and it can be used as a normal Ijl< type wide-mouth envelope by simply separating the envelope in size.Furthermore, since it is a wide-mouth envelope with an opening on the long side, it is easy to insert inserts, and the sealing part can be easily inserted. By making the crease line a crimp line, it becomes possible to automatically enclose the enclosed material, and it is expected to be used as a sealing part for automatic enclosing and sealing.

Furthermore, since the upper edge of the unit lower paper piece is removed monthly so that the upper paper part of the envelope is larger than the lower paper part of the envelope, the fold line between the upper paper part and the sealing part is closer to the M opening, that is, the lower paper part of the envelope. Since it is located above the upper edge of the T-paper section, there will be no cracks in the fold line of the sealing part at the upper edge of the T-paper section, and the confidentiality of the enclosed contents can be maintained. Since there will be enough space at both corners of the upper edge of the upper paper section and the top paper section for opening, opening the envelope will be extremely easy, and other effects as a unit envelope can be expected.
