Description

[Detailed description of the invention] This invention consists of unit envelope forms that are coated with adhesive at predetermined positions, and the adhesive is applied to the surfaces that overlap when folded in a zigzag pattern into one unit or multiple units. The present invention relates to a form for continuous envelopes configured so that adhesives do not come into contact with each other, and in particular, a form for continuous envelopes that has good non-impact feed suitability for printing addresses and notification information corresponding to the addresses.

Conventionally, continuous envelope forms that were constructed so that adhesives applied to their overlapping surfaces did not come into contact with each other when the connected unit envelope forms were folded in a zigzag pattern were devised in Japanese Utility Model Publication No. 55-27557. It became widely used as

However, the adhesive application pattern of conventional continuous envelope forms does not allow the adhesives to come into contact with each other, which is very effective during storage of the form, when feeding the form from a folded state to a flat state in a printer, and when manufacturing the form. However, in some non-impact printers, especially printers with a mechanism that uses heat, pressure, etc. to fix the print toner on the paper, when the continuous envelope form stops feeding for some reason, the thermal roll or The tension roll or the like is configured to be located on the connecting part of the unit form or on the tip side of the form after the connecting part, and when using a conventional continuous envelope form, the adhesive is attached to the roll when the feed is resumed. This caused the inconvenience that the feed could not be performed smoothly.

Therefore, in consideration of the above-mentioned drawbacks, in this invention, we researched the adhesion status of the roll and adhesive, and in particular,
We focused on the fact that the heat during toner fixation is applied from the surface side of the form, and that the roll is in contact with the leading edge of the subsequent form during re-feeding.The form for continuous envelopes is well preserved, and it is possible to continuously To provide a continuous envelope form which prevents adhesive from adhering to a roll even when the envelope form stops and has an adhesive band pattern suitable for mailing as an envelope.

Next, this invention will be explained based on drawings showing one embodiment of this invention.

FIG. 1 is a partially cutaway perspective view of a continuous envelope form 2 in which a unit envelope form 1, which is formed by horizontally consecutive three pieces of envelope top paper piece A, envelope inner paper piece B, and envelope bottom paper piece C, is connected. As shown in FIG. 2, the unit envelope form 1 is provided with a folding perforation 3 in a continuous portion of three paper pieces of each envelope piece A, B, and C, and along this folding perforation 3, as shown in FIG. When each envelope piece A, B, and C are folded in a Z-shape, the upper envelope piece A, the inner envelope piece B, and the lower envelope piece C are made into a book-like spread along the three peripheries of the envelope piece at the position where they overlap each other. Perforations 4 and 5 for opening are provided.

Of these opening perforations 4 and 5, the opening perforation 4, which is provided along the connecting part of the unit envelope form 1 at the upper and lower ends, is two-thirds inch (16.9 mm) from the connecting part. ) are set apart,
Opening perforation 5 is spaced one-half inch (12.7 mm) from the edge of the mailed envelope.

Further, on the outside of the opening perforations 4 and 5 and on the surface side of the inner envelope paper piece B and the lower envelope paper piece C of the unit envelope form 1, adhesive bands 61 and 6 with a width of approximately 4 mm are provided.
2, 63, and 64 are applied and provided, and adhesive bands 61', 62', 63', and 64' approximately 4 mm wide are also applied and provided on the back sides of the envelope top paper piece A and the envelope inner paper piece B, Moreover, the adhesive band 61 along the upper edge joint of the envelope inner paper piece B and the envelope lower paper piece C on the front side is applied so that the average edge of the upper end of the adhesive band is 10 mm away from the joint part, and the adhesive band 61 is applied to the upper edge of the envelope paper piece The adhesive band 62' along the lower end joint of the back side of envelope paper strip B and A is applied 10 mm away from the joint, and the adhesive band 62' is applied 10 mm away from the joint, and
The adhesive band 61' along the upper edge of the back side of the envelope is moved toward the connecting part by the width of the adhesive band so that it does not overlap with the adhesive band 61 provided on the back side of the inner paper piece B of the envelope in the transparent state of the form, and is placed 5 points closer to the connecting part than the adhesive band 61'. The adhesive band 62, which is applied at a distance of millimeters from the other side and along the lower edge of the front side of the inner envelope piece B, is arranged so that it does not overlap with the adhesive band 62' provided on the back side of the envelope inner piece B in the transparent state of the form. It is applied closer to the connecting part by the width and 5 mm away from the connecting part.

In addition, the adhesive bands 63 and 64 on the surface side of the inner envelope paper piece B and the envelope lower paper piece C applied along the direction perpendicular to the connecting part and on both ends are applied at the center of the upper and lower ends of the unit envelope form 1. , upper adhesive strip 63
The adhesive strips 63' and 64' on the back side of the envelope top paper strip A and the envelope inner paper strip B are placed in the middle of the upper and lower edges of the unit envelope form 1. In this case, the upper adhesive strip 63' is applied inside the lower adhesive strip 64', and the adhesive strips are applied at positions different from each other by at least the width of the adhesive strip.

In addition, transfer holes 9 are provided at both ends of the unit envelope form 1, transfer holes 10 are provided at every 1/2 inch interval, and the connecting portions of each unit envelope form 1 are provided with folding and/or Perforations 7 are provided for cutting.

In the above description, the adhesive strip is made of a pressure-sensitive adhesive, but a high-temperature adhesive may also be used.

Further, on the upper end side of the adhesive band 63, there is a protrusion 60 that protrudes about 3 mm from the side of the adhesive band 61 on the connecting part side, and this protrusion 60 improves the sealing on the end side. To improve adhesion, the adhesive strips 61 may be provided on top of the adhesive strips 61 at corresponding positions on the envelope pieces B and C.

Even when the continuous envelope form according to the invention as described above is folded in a zigzag manner along the perforations 7 for folding and/or cutting, the adhesive bands do not stick to each other, and therefore,
When used in a printer, it gradually changes from a folded state to a flat state and is fed smoothly. In addition, the printer's heat roll 11 and feed roll 1
1' is located on the connecting part of the unit form or on the tip side of the form subsequent to the connecting part, so that when the connecting part of the unit form stops in the middle of the feed, As shown in the figure, a heat roll 11 and a feed roll 1
1' stops at the tip side of the form subsequent to the connecting part (upper end of unit envelope form 1), the surface side of the unit envelope form to which heat is applied is exposed to adhesive from the connecting part. to the end of the band,
The distance is more than twice that of a normal adhesive strip (3 to 5 mm), and on the back side, the distance from the connecting part to the end of the adhesive strip is more than one time that of a normal adhesive strip. Therefore, even when using a pressure-sensitive adhesive, which does not come into contact with the roll and the adhesive strip and tends to adhere due to heat, the surface side to which heat is applied has the above-mentioned distance, so that it adheres to the roll. Never. In addition, when the envelope is made into an envelope, there is a non-adhesive area that is more than twice the width of the adhesive band from the edge of the envelope to the adhesive part, but the gap between the non-adhesive parts on the back side or front side is narrower, and the envelope is When this happens, the envelopes do not normally roll over and can be used without any problems during mailing.Also, the position and pattern of the adhesive strips are designed to allow heat to be applied from the front side of the envelope form. , the area of the notification information writing section can be reduced to a minimum, and opening is even easier.
