Description

[Detailed description of the invention]

0010

[Industrial Field of Application] The present invention relates to a folded envelope, which comprises an outer envelope formed by folding a plurality of connected partial paper sheets, and an enclosed paper leaf inserted into the envelope formed by the outer envelope. The present invention relates to a method for creating an envelope and materials for the envelope.

[0020]

[Prior Art] An automatic envelope creation device that automatically folds and forms a paper sheet with common or different information printed on it to be sent from a specific sender to a number of recipients. Post-processing devices (also called "post-processing devices") are already widely used and play a major role in saving labor in sending direct mail in banks, mail-order industries, and the like. Continuous foam paper, in which a large number of unit envelope sections are connected in the longitudinal direction, is used as a material for folding envelopes used in such automatic envelope creation devices. Each unit envelope consists of two or more partial sheets connected in the width direction via a fold line, and an automatic envelope creation device continuously folds these partial sheets along the fold line and applies hot adhesive. Alternatively, the partial sheets are glued together at the opening using a pressure adhesive to form a sealed envelope. The continuous foam paper that has been folded and sealed in this way is separated into individual envelope sections to create individual envelopes.

[0030]

[Problems to be Solved by the Invention] There are cases where it is desired to enclose another sheet of paper inside the sealed letter that is automatically created in this way. For example, there may be a case where it is desired to enclose paper of a different quality from that of the outer envelope of a sealed letter, or a case where it is necessary to enclose a sheet of paper that must go through a printing process different from that of the outer envelope. In such a case,
Conventionally, an automatic paper sheet inserting device was used in addition to the automatic envelope producing device. This automatic sheet enclosing device inserts separately prepared insert sheets between partial sheets of paper after the continuous form paper is folded by the automatic envelope creating device and before it is sealed. However, such an automatic sheet inserting device takes up a large amount of space and is expensive, so it has been difficult to use it except when producing a large number of sealed letters. The present invention was made to solve this problem, and its purpose is to provide an envelope that is prepared separately from the outer envelope without the need for expensive and large incidental equipment (automatic paper inserter). To provide a material for an envelope and a method for making an envelope, which can fold paper sheets and insert them into an envelope at low cost.

[0040]

[Means and operations for solving the problems] In order to solve the above problems, the envelope material according to the present invention is characterized by comprising the following elements. i) First and second sprocket hole rows are provided at both ends, a plurality of unit letter parts are connected in the longitudinal direction via a planned cutting line, and further, each unit letter part is connected to each other via a fold line. a first continuous foam paper that is divided into a plurality of partial sheets of approximately the same size in the width direction; and ii) at least the above-mentioned paper on the side edge corresponding to the opening side formed when the first continuous foam paper is folded. It has a third sprocket hole row corresponding to the second sprocket hole row of the first continuous form paper, and the unit enclosed paper sheet, which is narrower than the partial sheet of the unit envelope section, is cut in the longitudinal direction through the planned cutting line. a second continuous foam paper iii to be inserted into said opening of the first continuous foam paper, configured in conjunction;
) Openings formed at the side edges perpendicular and parallel to the fold line when the unit envelope consisting of the unit envelope part of the first continuous foam paper and the unit enclosed paper sheet of the second continuous foam paper is separated. a heat-sensitive or pressure-sensitive adhesive layer applied to at least one side of the partial sheet or the enclosed sheet for sealing the portion;

[0050] Note that the unit enclosed paper sheet of the second continuous form paper may be divided into a plurality of partial sheet sheets narrower in width than the partial sheet sheets of the unit envelope part in the width direction via the fold line. . In this case, the second continuous foam paper is folded at the fold line before being inserted into the first continuous foam paper.

The sealed letter production method according to the present invention is characterized by comprising the following steps. i) At the same time, two sprocket rollers fit the first and second sprocket hole rows of the first continuous foam paper, and at the same time, one of the sprocket rollers feeds the second row of sprocket holes.
The first continuous foam paper and the second continuous foam paper are overlapped with the third sprocket hole row of the continuous foam paper aligned with the second sprocket hole row of the first continuous foam paper. ii) Continuously folding the first continuous foam paper of the first continuous foam paper and the second continuous foam paper fed in an overlapping state so as to enclose the second continuous foam paper. iii) Bonding the first continuous foam paper and the second continuous foam paper through the adhesive layer by heating or applying pressure. iv) Cut into unit envelopes along the cutting line.

[0070] In order to carry out the above-mentioned envelope letter creation method, a conventional automatic envelope creation device (post-processing machine) is used as is, and when the first continuous form paper is continuously folded in the first part, Alternatively, the second continuous foam paper may be inserted between the already folded partial sheets of the first continuous foam paper immediately before the heating (or pressurization) step. You may also insert it. In addition, before sealing is performed using such an envelope creation device (post-processing machine), a device that processes continuous form paper called an automatic collating machine or the like is used to insert a second continuous form paper in the form described above. A continuous envelope material may be prepared by folding the first continuous form paper.

Embodiment FIGS. 1(a) to 1(d) are a plan (front) view and a bottom (back) view of a material for an envelope which is an embodiment of the present invention. The envelope material of this embodiment consists of a first continuous foam paper 10 having a wide width and a second continuous foam paper 11 having a narrow width. Sprocket hole rows 14 and 15 are provided at both ends of the first continuous foam paper 10, respectively. Although it is desirable that the hole sizes and arrangement pitches of both sprocket hole rows 14 and 15 be the same, they may be different. The first continuous form paper 10 is divided into a large number of unit letter parts 18 by cutting lines 17 arranged at regular intervals in the longitudinal direction (vertical direction in FIG. 1).
is divided into left and right partial sheets 12 and 13 by a fold line 16 running in the longitudinal direction at the center of the width direction (therefore, both partial sheets 12 and 13 have the same size). Each unit envelope 18
A stamp pasting field 19 and an address printing field 20 are provided on one side (front surface (a)) of one partial sheet 13, and a sender display field (not shown) is provided on the same side of the other partial sheet 12. is provided. A message is printed or written on the other side (back side (c)) of both the paper sheets 12 and 13. Sprocket hole row 14
, a cutout line 2 is placed slightly inward from 15.
1 and 22 are provided, but the planned cutting lines 17 between the unit envelope sections 18 may be omitted if the continuous form paper is used. A small interval (
Perforations 23, 23 are perforated in the width direction by taking about 10 mm). This is for the recipient to open the sealed letter after performing the sealing process described below.

The second continuous foam paper 11 is provided with a row of sprocket holes 26 only on one side. The size and arrangement pitch of the sprocket holes in this sprocket hole row 26 are the sprocket holes of one of the first continuous foam paper 10 (if the sizes or pitches of both sprocket holes 14 and 15 of the first continuous foam paper 10 are different). Assume that it is the same as 1st
Similar to the continuous foam paper 10, the second continuous foam paper 11 also has scheduled cutting lines 27 arranged at regular intervals in the longitudinal direction.
It is divided into a large number of unit enclosed paper sheets 28. The longitudinal size (length) of this unit enclosed sheet 28 is the same as the length of the unit envelope section 18 of the first continuous form paper (that is, the interval between the scheduled cutting lines 27 is the same as the interval between the scheduled cutting lines 17) However, the width of the unit enclosed sheet 28 is slightly smaller than the width of each partial sheet 12, 13 of the first continuous foam paper 10. A planned cut line 29 is provided slightly inside the sprocket hole row 26, and perforations 30, 30 are provided in the width direction on both sides of each planned cut line 27 between the unit enclosed paper sheets 28. There is.

[0100] In the narrow areas between the perforations 23, 23 on both sides of the planned cutting line 17 between the unit envelope sections 18 on the back side (c) of the first continuous form paper 10 and the planned cutting line 17, The adhesive 32 is applied over almost the entire width except for the vicinity of the fold line 16 and the sprocket hole rows 14 and 15.
(Depending on the circumstances of the adhesive applicator, it may be applied near the fold line 16 or in the sprocket hole rows 14 and 15.)
(You may apply some parts). Correspondingly, the perforations 30, 30 on both sides of the planned cutting line 27 between the unit enclosed paper sheets 28 of the second continuous form paper 11 and the planned cutting line 2
Adhesive 33 is also applied to the narrow area between 7 and 7. On the other hand, the upper and lower planned cutting lines 1 are also located just inside the planned cutting lines 21 and 22 on both sides of the first continuous form paper 10.
Adhesives 34 and 35 are applied in a band shape over almost the entire length of the unit envelope section 18 except for the vicinity of 7. (You may also apply it continuously.) However, in the corresponding part of the second continuous foam paper 11,
Do not apply adhesive. All of these adhesives are heat adhesive type (also called "heat seal") or pressure adhesive type (also called "dry seal"; for example, those using microcapsules), and the first continuous When handled as foam paper 10 and second continuous foam paper 11, they do not have any adhesive ability at room temperature (therefore, no release paper is required).

[0110] Next, a method for creating an envelope containing an enclosed paper sheet from the envelope materials (first and second continuous foam papers 10, 11) prepared in this way will be explained. One method is to use a first continuous foam paper 10 as shown in FIG. 2(a).
In this method, the second continuous foam paper 11 is stacked on top of each other in the opened state, and the other method is as shown in FIG.
When the continuous foam paper 10 is folded, the second continuous foam paper 11 is sandwiched therebetween. In the method (a), the sprocket hole rows 14 at both ends of the first continuous foam paper 10
, 15 with sprocket rollers 38, 39 that match their respective sizes and pitches (the distance between these two sprocket rollers 38, 39 is equal to the distance between the sprocket hole rows 14, 15 of the first continuous foam paper 10). Multiply by Next, the sprocket hole row 2 of the second continuous foam paper 11
6, one of them (the first one having the same size and pitch as the sprocket hole row 26 of the second continuous foam paper 11)
Hang it on the sprocket roller 39 of the continuous foam paper 10 (the one on which the sprocket hole row 15 is hooked). After setting the bicontinuous foam paper 10 and 11 one on top of the other by one of the sprocket rollers 39 in this way, both sprocket rollers 38 and 39 are rotated, and the bicontinuous foam paper 1
0 and 11 are sent at the same time. Thereafter, the first continuous foam paper 10 is successively and gradually folded along the central fold line 16 while the second continuous foam paper 11 is sandwiched therein, until the paper is finally folded as shown in FIG. 3(a). The first continuous foam paper 10 is completely folded in half. In the method shown in FIG. 2(b), the first continuous foam paper 10 is folded in half and hung on one sprocket roller 37 with the second continuous foam paper 11 sandwiched therebetween.

[0120] The first continuous foam paper 10 folded in half in this way is heated or pressurized from both sides to form the adhesive 3.
2, 33, 34, 35 are activated and the first and second continuous foam papers 10, 11 are glued together. The cross section taken along the line B-B and line C-C in FIG. 3(a) in this state is shown in the same figure (
Shown in b) and (c). At this time, since adhesives 32 and 33 are applied to both sides of the first continuous foam paper 10 and the second continuous foam paper 11 at the upper and lower ends of the unit envelope section 18, both continuous foam paper 10 and 11 The bond between them becomes very strong and becomes a permanent bond. However, at the opening at the side end of the unit envelope section 18, the first continuous foam paper 1
Since the adhesives 34 and 35 are applied only to the second continuous foam paper 11 and not to the second continuous foam paper 11, the adhesion between the two continuous foam papers 10 and 11 is weak, and it is easy to tear the envelope paper with your fingers later. The package is ready to be opened (without any damage).
This is called a "pseudo-adhesion" state). The glued continuous foam paper 10, 11 is first cut along the planned cutting lines 21, 22, 2.
At 9, parts of the sprocket hole rows 14, 15, and 26 are cut out, and then cut along cutting lines 17 and 27 in the width direction to separate the letters into individual envelopes. Since each sealed letter is adhesively sealed at the top, bottom and side edges with an adhesive layer, it can be mailed as a sealed letter according to the postal method. The recipient tears the envelope at the upper and lower perforations 23 and 30, opens the upper and lower ends, and inserts his/her finger into the seal to easily open the pseudo-adhesive part of the seal opening at the side edge without damaging the envelope. be able to.

Next, as a second embodiment of the present invention, an example in which the outer envelope of a sealed letter is composed of three partial sheets will be described. In this case, as shown in FIG. 4(a), the first continuous foam paper 40 is divided into three rows in the width direction by two fold lines 41 and 42, and the first continuous foam paper 40 is divided into three rows in the width direction by two fold lines 41 and 42. folded into. The folding method is shown in the same figure (b
There are two types of paper that can be considered: a Z-shape as shown in Figure 1 (c) and a C-shape as shown in Figure 1 (c). By using the sprocket roller in common with the first continuous foam paper 40, it is inserted into the inside of the first continuous foam paper 40 from the opening. 5 and 6 (enlarged view of the sprocket rollers 43 and 44 in FIG. 5) show the state in which the bicontinuous form papers 40 and 11 are continuously overlapped in the automatic envelope producing device containing insert sheets using the present invention. Shown below. The adhesion between the first continuous foam paper 40 and the second continuous foam paper 11 is the same as in the first embodiment, with permanent adhesion at the upper and lower ends of the unit envelope and pseudo-adhesion at the side edges. , an adhesive is applied to appropriate locations on the upper and lower ends and side edges of the planned cutting line of the first and second continuous foam papers 40 and 11.

[0140] As a third embodiment of the present invention, a case will be described in which the enclosed paper sheet consists of a plurality of partial paper sheets. In this case, the second continuous form paper 50 is wide and divided into two partial sheets 52 and 53 by a central fold line 51, as shown in FIG. Foam paper (
10) Before being inserted into the inside of the paper sheet 10, it is folded in two at the fold line 51 as shown in FIG. It takes the form of A cross section of the second continuous foam paper 50 inserted into the first continuous foam paper 10 is shown in FIG. 7(c).

[0150] As explained above, the first continuous form paper to be the outer envelope of the sealing material according to the present invention can be made up of two or more partial paper sheets, and the second continuous form paper can be made up of a single sheet or two partial sheets. It can be composed of more than one sheet of partial paper. In addition, if the second continuous form paper inserted inside is a single sheet (consisting of only one partial sheet), sprocket hole rows may be present on both sides for convenience during printing. I do not care. In any case, in the present invention, in the step of creating an envelope containing an envelope (the step of inserting an envelope), only one row of sprocket holes is used for the second continuous foam paper to be inserted.

[0160] In the above description of the embodiment, pseudo-adhesion to facilitate the recipient's opening of the sealed letter is performed by applying adhesive only to one side of the stacked paper sheets. However, various methods can be used to more subtly change the adhesive strength and make opening easier. As shown in FIGS. 8(a) and 8(b), one method is to apply an adhesive nullifying layer 71 overlapping the adhesive layer 70 and forming a part thereof (in the form of diagonal stripes in the figure) to nullify the adhesive. It is called printing (or coating). As the adhesion nullifying layer 71, a resin film (or metal foil, etc.) that is not adhered to it can be used as appropriate depending on the adhesive used, but printing with ordinary ink can also serve its purpose. In the case of FIG. 8, the strength of the pseudo adhesion can be arbitrarily changed by appropriately adjusting the thickness or interval of the adhesion nullifying layer 71 which has a diagonal stripe shape. This, on the contrary, allows the use of adhesives of arbitrary strength, and also allows the use of low-cost adhesives. Note that, as shown in FIGS. 7(c) and 7(d), the adhesive nullifying layer 73 may be printed on the opposite side of the adhesive layer 74 instead of being printed on the adhesive layer 74. Further, as for the shape of the adhesion nullifying layer, various patterns such as a mesh shape, a polka dot shape, etc. can be used in addition to the stripe shape shown in FIG.

Another method for facilitating unsealing at the pseudo-adhesive area is to vary the area of the adhesive layer. One embodiment is shown in FIG. 9, in which the adhesive layer 80 at the location where pseudo-adhesion is to be performed (in this example, the side edge portion) is formed in two rows of strips. Optimal adhesive strength can be obtained by appropriately adjusting the width and number of rows of this band-shaped adhesive layer depending on the type of adhesive (adhesive strength) used. Furthermore, if coated paper (also called coated paper or art paper) is used, pseudo-adhesion will occur even if adhesive is applied to both sides. In Figures 8 and 9, the adhesive strength is adjusted only at the side edges of the sealed letter, but even at the upper and lower sealing areas, the above adhesive is used instead of applying strong permanent adhesive and opening the seal at the perforations. It is possible to create pseudo-adhesion with adjusted strength.

[0180] If the adhesive strength of the pseudo-adhesive portion of the envelope is insufficient, the pseudo-adhesive portion may peel off naturally during mailing. One way to prevent such accidents is to adjust the adhesive strength of the pseudo-adhesive part to an appropriate value as described above. A part of the side end portion, which is the adhesive portion, may be permanently bonded. In FIG. 10, only one place 90 in the center is permanently bonded, and in FIG. 11, three small places 91, 92, and 93 in the center and both ends are permanently bonded. By doing so, it is possible to prevent the envelope from being opened spontaneously during mailing, but it also does not make it difficult for the recipient to open the envelope.

[0190] In the three-fold envelope shown in Fig. 4, the outer envelope is completely spread, but the enclosed paper sheet of the present invention can also be enclosed in a so-called book-bound type envelope. In this case, a developed view of the front surface of the outer package (first continuous foam paper) and the enclosed sheet (second continuous foam paper) is shown in FIG. 12, a developed view of the back surface is shown in FIG. 13, and the state of folding is shown in FIG. In this example, the outer envelope (first continuous foam paper) 100 is folded into a Z-shape, and the enclosed paper leaf (second continuous foam paper) 10
1 is one opening (the right side 10 on the front side in Fig. 12).
3, 104). At this time, the second continuous foam paper 101 is inserted using only one sprocket hole row 105. After the envelope is sealed, when it is opened at the perforations 120, 121, and 122 at the top, bottom, and left and right edges,
The enclosed paper leaf 101 is separated from the outer envelope 100 of the sealed letter, and the outer envelope 1 is separated.
00 is opened into a bookbinding mold with the adhesive layer 110 at its back.

[0200]

[Effects of the Invention] As explained above, by using the material for folded envelopes with paper inserts and the method for producing envelopes according to the present invention, it is possible to use ordinary paper leaf inserters without using an expensive and large special paper leaf inserter. Paper sheets can be inserted into envelopes using a folding envelope producing device. Furthermore, since the enclosing is performed continuously, the processing speed can be increased, and separate sheets can be enclosed at low cost.
