Description

Envelopes {ENVELOPE}

Conventionally, since the standard or non-standard envelopes are made by folding a single sheet appropriately, the basic structure is inevitably common, and the overlap that the bonding is at the center, and the horizontal lattice for joining both sides up and down ( I), a variety of things are known, such as a bale nip, the side of which is the inner and outer sides of the bottom face, and a daiap, the tip of the flap being driven around the center and the joining portion being oblique.

For example, what is shown in FIG. 1 belongs to the type called said bale nip, the sheet | seat which folded one sheet of paper and pasted together, the surface sheet (1) which has a name and address surface, and the back sheet (2) which has a folding surface And flaps 3 are formed. If the envelope is a general standard type, it is completed by bonding the front sheet 1 and the back sheet 2 through the pasting blades A extending from the side edges of the front sheet 1.

However, in recent years, the spread of computers has been remarkable not only for office use but also in homes, and in response to this, the spread of printers has become widespread. In addition, with the spread of printers, address printing and writing of names are also frequently performed. In addition to the above-mentioned address and name, there is a request to print the sender's logo or decoration on any part of the envelope.

However, for example, in the conventional envelope as shown in FIG. 1, the part corresponding to the blade | wing wing A becomes a triple layer of paper, and a difference arises in thickness because a center part becomes a double layer. As a result, in the case where the envelope is passed through the roller, a gap is formed between the rollers in the center portion, which is the printing portion, and clean printing may not be possible.

In addition, when passing between the conveying rollers, wrinkles may occur due to the difference in the strength of the paper caused by the difference in thickness, or the fixing degree of the ink may change due to the difference in thickness, It may be dispersed.

In addition, since the front sheet and the back sheet overlap each other through the left and right paste blades, the adhesion between the two sheets is poor, and the sheet conveyed by the driving roller and the sheet conveyed by the driven roller slide, resulting in a difference in conveying amount. Another problem is that smooth transfer and accurate printing are not performed. In addition, the above-mentioned various known envelopes always have pasting blades, so that the same problem arises due to a part having a different thickness, and this problem is particularly remarkable in a laser printer.

Disclosure of Invention The present invention aims to solve the above-described conventional problems, and discloses a structure of an envelope capable of printing a reliable address and name even when applied to a widely-used printer.

In the present invention, in order to achieve the above object, the sheet is folded in two to form a back sheet having a folding surface and a surface sheet having a name and address surface, and an opening is formed between the surface sheet and the back sheet. The encapsulation region having the encapsulation region is formed, and the facing surfaces of the surface sheet and the back sheet are directly bonded at edge portions except for the opening and the folding line, and the surface sheet and the back sheet are substantially overlapped with each other. In this case, approximately the entire area of the encapsulation area is composed of the same number of sheets.

In such a configuration, since the front sheet and the back sheet are directly bonded together without interposing the blades to be pasted, the thickness can be equalized. Problems at the time, i.e., wrinkles, change in fixation of ink, and dispersion of printing in portions of the step can be effectively prevented. In addition, since the adhesion between the front sheet and the back sheet is much better than the conventional one, it is not easy to shift even when passing between the printer rollers, and smooth conveyance can be performed.

In addition, since there are no blades to be pasted, the development sheet becomes rectangular or close to a rectangle, and the yield when cutting the development sheet from the base paper is improved. Furthermore, since the process of folding the pasting blade can be omitted, the manufacturing process can be simplified.

In addition, it is also possible to open the side by the capacity to grab the surface and the back. Of course, even when writing a name and address by hand, there is no difference in thickness, it goes without saying that it can be used in a very good condition.

On the other hand, with the above structure, since the surface sheet and the back sheet overlap each other, it is difficult to expand the opening, and when it is expanded, there is a possibility that a load directly acts on the paste joint and the part is peeled off or damaged. have. In order to prevent such a problem, it is preferable to form a notch in the edge portion facing the opening of the back sheet.

Moreover, even in the state which closed the opening by a flap, in order to make thickness uniform, it is conceivable to make the flap for closing the opening of a sealing area into the shape which substantially overlaps a back sheet.

On the other hand, if the front sheet and the back sheet have exactly the same shape, depending on the folding accuracy, an error occurs in the joint at the time of making the bag, and the back sheet sticks out to one side. If this envelope is applied to a printer, this protruding portion may be disturbed and paper clogging or roller wrinkles may occur in the printer, thereby preventing reliable printing.

In order to prevent this problem, the back sheet and the flap are formed by folding lines on both sides of the surface sheet, and the front sheet and the back sheet are directly attached to each other and the back sheet is folded or folded. It is preferable to form an undercut of the width gradually narrowing away from the regular interval at.

In this way, if the back sheet is gradually narrowed at the fold line, the back sheet may not protrude outward from the surface sheet even when there is a slight error when the bag is folded in half when the bag is manufactured. will be

Here, "slowly narrowing" is a concept that includes narrowing in a step shape.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment suitable for this invention is described according to attached drawing. In addition, the same code | symbol is used for the corresponding part in each following embodiment.

First Embodiment

As shown in the developed view (Fig. 2) and completeness (Fig. 3), the envelope F in the present embodiment folds the development sheet ST in two, and has a surface sheet 10 and a back sheet having an address and a statement surface. (11) is formed and it is a rectangle formed by forming the sealing area | region S between these front sheet | seat 10 and the back sheet | seat 11.

The fold line 13 for folding in two is configured to correspond to the long side portion f1 of the envelope F, and has a surface at the side edge portion f2 that is a short side portion adjacent to the fold line 13. By bonding the sheet 10 and the back sheet 11, the encapsulation region S is opened to the opposite side of the fold line 13.

On the other hand, from the long side part f4 which opposes the said folding line 13 of the surface sheet 10, the flap 12 extends integrally through the 2nd folding line 14, and this flap 12 The opening 17 of the encapsulation region S can be sealed by covering the cover with the second fold line 14.

However, in this embodiment, the adhesion part 20 is set in the surface 10b, 11b which mutually opposes in the short side part f2 of the said front sheet 10 and the back sheet 11, and this adhesion part ( The surface sheet 10 and the back sheet 11 are directly bonded by applying an adhesive to 20).

In addition, the adhesive portion 20 is placed over the entire short side portion f2 so that the sealing region S can be completely enclosed. Therefore, a portion which is not adhered to a part of the short side portion f2 may be disposed depending on the purpose. You may form.

In the present embodiment, the front sheet 10 and the back sheet 11 are of the same shape, and in the state where the envelope F is completed, the front sheet 10 and the back sheet 11 overlap each other. It consists.

In general, in the conventional envelope, since the folding portion is not strongly folded in consideration of the texture, etc., the thickness of the folding portion is a little larger, and when a large number is stacked, the folded portion is swollen compared to the opposite side. In the form, by folding the fold line 13 more strongly than before, the thickness is made uniform, and even when a large number is stacked, the stacked envelopes F have the same thickness as a whole.

According to this embodiment comprised in this way, since the substantially whole area | region of the said sealing area S is comprised by the same number of sheets, the thickness becomes equal, and the problem at the time of printing which arises because there exists a part which differs in thickness conventionally, That is, it is possible to effectively prevent wrinkles, partial fixation of the ink, or dispersion of printing in the stepped portion.

In addition, since the adhesion between the front sheet 10 and the back sheet 11 is significantly improved as compared with the conventional one, an error hardly occurs even when passing between the rollers of the printer, and smooth transfer is possible.

In addition, even if several sheets are overlapped, the overlapped envelopes F become equal in thickness, so that they can be stacked on a feeder (feeder) for continuous printing without problems, and furthermore, suitable for storage and packaging. .

Of course, there is no difference in thickness even when writing the address of the envelope by hand, not to mention that it is very convenient and appropriate.

Since there is no blade to paste from the viewpoint of manufacture, the development sheet ST becomes a rectangle or a shape close to the rectangle, and the yield at the time of removing the development sheet ST from the base paper can be improved significantly. . In addition, since the folding process of the paste can also be omitted, the manufacturing process can be simplified.

Second Embodiment

4 shows one form when the envelope F of the present embodiment is developed, 10 is a surface sheet having a base surface of an address and a name, 11 is a back sheet having a folding surface, and 12 is a sealing flap. 13 and 14 are folding lines which are formed at the same time when the envelope F is formed by disassembling one by one. Here, the surface sheet 10 is an exact rectangular shape, but the back sheet 11 is formed of a tapered undercut 15 which is gradually narrowed from the folding line 13 side toward the opening 17 side.

FIG. 5 shows a state in which the sheet is folded in half in the fold line 13 in the structure of FIG. 4, and both sides are bonded together with an adhesive in the bonding portion 20 to be completed as an envelope F. As shown in FIG.

The technical point of particular importance in the structure of this invention is not to make the back sheet 11 into the rectangle which matched the surface sheet 10, but to make it taper shape gradually narrowed.

As shown in FIG. 12, when the sheet is completely matched with the first embodiment, the back sheet 11 is deviated from the surface sheet 10 depending on an error, and thus the shape as the entire envelope F is inadequate. Error occurs, the appearance is also worsened, there may be a problem in printing and the like.

However, by configuring as described above, even if a slight error occurs in the case of mechanical folding on the fold line 13, the back sheet 11 does not protrude from the surface sheet 10. Therefore, if only the shape of the surface sheet 10 is correct, no difference occurs in the shape of the entire envelope F, and even when applied to a printer, it is inclinedly supplied to the roller or overlapped with a plurality of sheets in the feeder. Even if there is no protruding part, it can solve the problem of twisting and folding.

Third Embodiment

FIG. 6 shows the third embodiment and starts the middle of the folding line 13 and the opening 17 without starting the start of the undercut 15 on the folding line 13. The envelopes are formed by disassembling one by one, and since the mechanical folding is performed at the part of the fold line 13, no excessive error occurs when folding. Therefore, in this case, it is considered that the undercut 15 can be prevented from popping out even if the undercut 15 is not started.

Moreover, in order to be able to exhibit the same effect as the above-mentioned embodiment, as shown in FIG. 13, the side edge part f2 of the back sheet 11 is made into the step shape, and the width of the back sheet 11 is front-end | tip. As shown in FIG. 14, the width of the back sheet 11 may be set to be narrower than the width of the surface sheet 10 as shown in FIG. 14.

Fourth Embodiment

As shown in FIGS. 7-9, the envelope F of this embodiment forms incision K in the both sides of the long side part f3 which forms the said opening 17 in the back sheet 11, have. Specifically, this cutout K is formed by cutting the long side portion f3 into a V-shape, and is set to be positioned slightly inward of the bonding portion 20. In this way, not only the opening 17 is easy to be unfolded, but also when the opening 17 is expanded to insert or withdraw the inclusion object OB, a stress acts on the site of the incision K, Peeling force is not directly applied to the adhesive portion 20. Therefore, even if the opening 17 is opened too much, a crack occurs at the cutout K portion, and if the crack is somewhat present, the flap 12 can be covered by adhering to the back sheet 11. As a result, the problem of not being able to seal the sealing region S can be avoided.

In addition, the magnitude | size, shape, a position, etc. of the cutout k are not limited to this embodiment, You may make it cut in only one of them.

Other Embodiments

Even in the state where the opening 17 is sealed by the flap 12, the flap 12 for closing the opening 17 of the encapsulation area is provided with a surface sheet 10 so as to make the thickness even. ) Or a shape substantially overlapping the back sheet 11 can be considered.

In each of the above embodiments, the fold line 13 has been described on the premise of a bag having a horizontal length such that the fold line 13 corresponds to the long side portion f1. However, as shown in FIG. ) May be used. However, in the case where the envelope F is automatically produced by using a bending machine (folding machine), the expansion sheet ST is lengthened when the above configuration is used. Therefore, the envelope to be produced is limited due to the functional limitation of the bending machine. The magnitude | size of (F) may be restrict | limited small compared with the thing of the said Example.

In addition, you may perform adhesion | attachment with a front sheet and a back sheet by what kind of method. In addition, the present invention is not only intended for the completed envelope, but also for the facing two-sided state in which the end user processes the adhesive surfaces on both sides.

As described in detail above, according to the present invention, since the edges of the back surface of the front sheet and the back sheet are directly bonded to each other so that the thickness is uniform, the printing at the time of printing caused by the presence of different portions of the thickness as in the prior art Problems, i.e., wrinkles, change in fixability of ink, or dispersion of printing in portions of the step can be effectively prevented.

In addition, since the adhesion between the front sheet and the back sheet is much better than the conventional one, no deviation occurs when passing between the printer rollers, and smooth conveyance can be performed.

In addition, since there is no pasting blade, the yield at the time of cutting out a development sheet from a base paper improves, and since the process of folding a pasting blade can be skipped, a manufacturing process can also be simplified.

Moreover, the opening from the side is also possible by the capacity | capacitance which peels off a surface and a back surface. Of course, there is no difference in thickness even when writing the address and the name by hand, so it goes without saying that the state becomes very reasonable. If the back sheet has a width that gradually narrows from the folding line or away from the folding line at regular intervals, a folding error occurs when the surface sheet and the back sheet are folded at the folding line, or they fall out of the frame. However, even if a slight error occurs, the back sheet does not stick out to the side because it is undercut, and even if it is used in the printer for address writing, it is sure that paper clogging or distortion occurs. Can be prevented.
