Description

  The present invention relates to a sealed letter. Specifically, the information is described on the inner surface side of the envelope body, and for example, it relates to a sealed letter that is extremely easy to enclose and seal printed matter such as advertisements and advertisements.

A conventional sealed letter folds a sheet of complicated development and encloses the printed matter in a glued envelope.
As a means for eliminating the troublesomeness associated with handling the envelope, there is a form-integrated envelope disclosed in, for example, Japanese Patent Application Laid-Open No. 11-147541. In this case, the sticking piece, the upper paper piece, the lower paper piece, and the middle paper piece are connected to each other through a crease, and the sticking piece, the upper paper piece, the lower paper piece, and the middle paper piece are inward of predetermined dimensions from the respective upper and lower edges An envelope form in which an opening perforation is formed parallel to the upper and lower edges at the position of the sheet is wound with the inner paper piece inside and between the upper and lower edges of the direction perpendicular to the fold and the opening perforation. A calibration in which a printed material is inserted between the upper paper piece and the middle paper piece formed by adhering with a pressure sensitive adhesive, and the sticking piece is folded on the lower paper piece and adhered and sealed with an adhesive. Is.

  JP 11-147541 A

  The seal of the cited document is formed by forming a crease between the sticking piece and the upper paper piece with the opening perforation, and after cutting off the upper and lower ends of the sealed letter, the upper paper piece is attached to the opening perforation. By separating the piece, it can be easily opened into a large piece of paper.

  In addition, by applying a pressure-sensitive adhesive and an adhesive (rewetting adhesive) in the process of creating an envelope form, an envelope can be obtained simply by being folded and pressed by a commonly used folder. In addition, it is said that a printed matter can be enclosed with a generally used sealing and sealing machine and sealed with an adhesive (rehumidified adhesive) to easily form a sealed letter.

  However, since the sealed document of the cited document has a perforation for opening, the upper and lower ends of the sealed document are cut and discarded. Moreover, since the upper and lower ends of the sealed letter are cut, the information description surface is limited. Furthermore, if the excision is not successful and not only the main body but also the printed matter enclosed is damaged, there is a disadvantage that various kinds of information cannot be confirmed.

  In addition, since it is necessary to apply an adhesive (rewetting adhesive) with a different property from the pressure-sensitive adhesive to a spot-determined spot, not only the number of work steps is increased, but also the work is difficult to use. The generation of non-defective products also increases. Furthermore, the manufacturing process of the envelope and the sealing and sealing process are separated, and in that respect, the number of processes is large and complicated.

  In view of the above problems, the present invention has no restrictions on the information description surface because no dust is produced at the time of opening, and the printed matter enclosed as well as the sealed letter body is not damaged at the time of excision at the time of opening. The sealed letter manufacturing process and the sealed sealing process provide a very simple sealed letter.

  In order to achieve the above object, the sealed letter of the present invention is a pseudo-adhesive medium in which a plurality of leaf pieces connected via a fold line are folded, and the opposing surfaces of any opposing leaf pieces are formed on substantially the entire opposing surface. A seal attached in a releasable manner, wherein an inclusion is sandwiched between the opposing surfaces, and the pseudo-adhesive medium on the outer periphery of the inclusion is attached in a peelable manner and sealed It is characterized in that it does not adhere at the part where the object and the pseudo-adhesive medium contact.

  As the material used for the base material of the sealed letter of the present invention, paper, synthetic paper, plastic resin, non-woven fabric and the like can be suitably used.

The pseudo-adhesive means includes the following.
(1) A pseudo-adhesive resin is applied to the surface to be pseudo-adhered on the surface of the paper after printing, and a pseudo-adhesive film is formed to realize peelable adhesion. Such a pseudo-adhesive means is called “post-glue method, varnishing method” in the industry.
(2) A pseudo-adhesive medium that is impregnated by applying a pseudo-adhesive medium containing, for example, synthetic rubber or natural rubber as a main ingredient to the paper before printing, and then printing out from the printed ink. To achieve peelable adhesion. Such a pseudo-adhesive means is referred to in the industry as a “tip glue system, pressure-bonded paper”.
(3) A pseudo-adhesive film sheet is coated on the printed paper surface to realize peelable adhesion. Such a pseudo-adhesive means is called “film system” in the industry.

  As the film method of (3), there is a pseudo-adhesive film sheet for print lamination. As shown in FIG. 12 (A), for example, one of the base materials 41 made of polyethylene terephthalate or biaxially oriented polypropylene is used. A three-layer structure corresponding to the thermal laminating method in which a known heat-sensitive adhesive layer 42 is formed on the other surface and a pseudo-adhesive layer 43 is formed on the other surface, as shown in FIG. A two-layer structure corresponding to a dry lamination method in which the heat-sensitive adhesive layer 42 in the three-layer structure pseudo-adhesive film sheet G is omitted and an adhesive is applied can be used.

  The aforementioned pseudo-adhesive film sheet can be peeled off when the pseudo-adhesive surface of the printed paper is coated and then folded so that the pseudo-adhesive layer 43 faces and subjected to pressure or heating / pressurizing treatment. If it peels after that, it can peel from between the said pseudo adhesion layers 43. The pseudo adhesive layer 43 is detachably bonded only by the treatment only when the pseudo adhesive layers 43 face each other, and does not adhere at all even when the treatment is performed opposite to the layers other than the pseudo adhesive layer 43.

  The leaf pieces forming the sealed letter of the present invention are connected by folding lines, but folding means such as folding sewing machines and folding lines may be formed on the folding lines. The folding sewing machine may be applied only to the base material that forms the sealed letter body in the state in which the above-described pseudo adhesive medium is formed, or may be applied to both the base material and the pseudo adhesive medium.

  As the opening means for the sealed letter of the present invention, for example, one of the opposing leaf pieces may be cut out and a step generated at the corner portion when folded may be used as an opening for peeling. Alternatively, a breaking perforation may be formed on an arbitrary edge, and the opening may be bent at the time of opening to break and open the perforation. Further, by making the widths of the opposing leaf pieces different, a step generated when the sheets are folded may be used as the beginning of peeling.

The sealed letter of the present invention has no portion to be cut off when opened. Therefore, no trash is produced.
In addition, since there is no work to cut off, there is no chance of accidentally damaging the information described inside or the enclosed material, and there is no cut-off portion, so that the entire surface can be used as an information description surface.
And when manufacturing sealed letters, the sealed letter is completed simply by sandwiching the printed material between the opposing leaf pieces and applying pressure or heating / pressurizing treatment, so there is no need for a large-scale device and the process is easy to manage. There is almost no outbreak.
Furthermore, if a pseudo-adhesive film sheet is selected as the pseudo-adhesive medium, the sealed letter is protected by a tough film sheet, so it is resistant to water wetting and breakage. Completely protected from.

Hereinafter, the present invention will be described in an easy-to-understand manner with reference to the drawings.
[Folded letter F1]
FIGS. 1A and 1B show a sealed letter sheet S1 of the basic two-fold sealed letter F1 of the present invention.
As shown in FIG. 1A, the sealed sheet S1 has a leaf piece 1 and a leaf piece 2 connected to each other via a fold line 3 (folded sewing machine is formed), and one corner of the leaf piece 1 is cut. Yes. And although illustration is abbreviate | omitted on the surface of the 1st leaf piece 1, general information, such as an advertisement, is described. Further, a postage mark, the address name of the recipient of the sealed letter, etc. are written on the surface of the second leaf piece 2.

  As shown in FIG. 1 (B), the back surfaces of the first leaf piece 1 and the second leaf piece 2 are covered with a pseudo-adhesive film sheet G (hereinafter, a cross-sectional view is expressed by one layer), and the illustration is omitted. However, the personal information and the general information described on the backs of the first leaf piece 1 and the second leaf piece 2 can be seen through the pseudo adhesive film sheet G.

  As shown in the cross-sectional view of FIG. 2, the folding machine formed at the fold line 3 penetrates the paper as the base material of the sealing sheet S1, and the pseudo adhesive film sheet G covering the paper penetrates. However, both of them may penetrate. A folding line may be used instead of the folding sewing machine.

  As shown in FIG. 3, the sealed sheet S <b> 1 configured as described above is opposed to the back surfaces of the first leaf piece 1 and the second leaf piece 2 (both are covered with the pseudo adhesive film sheet G) from the fold line 3. In this case, for example, the printed material X is arranged and sandwiched between the second leaf pieces 2 at a position indicated by a two-dot chain line. If pressure or heating / pressurization treatment is performed in this state, the pseudo adhesive film sheets G on the outer periphery of the printed matter X are adhered to each other at a portion facing each other so as to be peeled off and sealed.

  As shown in FIGS. 4 (A), 4 (B) and FIGS. 5 (A), (B), the two-fold sealed letter F1 manufactured by the above-described process is a single sheet-like sealed letter in which the printed material X is enclosed. Since the recipient of this sealed letter F1 can pick up the level difference caused by the corner cut at the lower right corner shown in FIG. is there.

  5A and 5B, the adhesive state of both leaf pieces is such that the portion of the outer periphery of the printed material X facing the pseudo adhesive film sheet G is detachably bonded, and the printed material X and the pseudo material are simulated. The portion in contact with the adhesive film sheet G is not bonded at all. Therefore, the printed matter X can be easily taken out from the two-fold sealed letter F1 developed on the plane after opening, even though it is sealed at the time of mailing.

[Tri-fold sealed letter F2]
6A and 6B show a sealed sheet S2 of the tri-fold sealed letter F2 of the present invention.
As shown in FIG. 6A, the sealed sheet S2 is formed by connecting the first leaf piece 11, the second leaf piece 12, and the third leaf piece 13 via folding lines 14 and 15 (folded sewing machines are formed). The cut sewing machines 16 and 17 are formed along the left edge of the first leaf piece 11 and the third leaf piece 13. And the postage mark, the address name of the recipient of the sealed letter, etc. are written on the surface of the first leaf piece 11, and the surface of the second leaf piece 12 and the third leaf piece 13 which are folded and concealed after the completion of the tri-fold sealed letter F2. The pseudo adhesive film sheet G is covered, and although not shown, personal information and general information described on the surfaces of both leaf pieces can be seen through the pseudo adhesive film sheet G.

  Further, as shown in FIG. 6B, the back surfaces of the first leaf piece 11 and the second leaf piece 12 that are folded and concealed after the completion of the three-fold sealed letter F2 are covered with the pseudo-adhesive film sheet G, and the illustration is omitted. However, personal information and general information written on the surfaces of both leaf pieces can be viewed through the pseudo-adhesive film sheet G. Moreover, since the back surface of the third leaf piece 13 is expressed as the back surface of the sealed letter after being folded, general information and the like are described although illustration is omitted.

  7A and 7B, the cut sewing machines 16 and 17 formed along the left edge of the first leaf piece 11 and the third leaf piece 13 are the base material of the sealed sheet S2. Pseudo-adhesive film sheet G that covers the sheet and also penetrates the sheet. Further, the folding sewing machine formed on the folding lines 14 and 15 penetrates the paper as the base material of the sealed sheet S2, and the pseudo adhesive film sheet G covering the paper does not penetrate, but both penetrate. It doesn't matter. A folding line may be used instead of the folding sewing machine.

  As shown in FIG. 8, the three-fold sealed letter sheet S <b> 2 configured as described above has a back surface of the first leaf piece 11 and the second leaf piece 12 from the fold line 14 (both are covered with the pseudo adhesive film sheet G). However, the fold line 15 is folded so that the surfaces of the second leaf piece 12 and the third leaf piece 13 (both are covered with the pseudo adhesive film sheet G) are opposed to each other. The printed materials Y and Z are sandwiched between the leaf pieces. If pressure or heating / pressurization treatment is performed in this state, the pseudo adhesive film sheets G on the outer periphery of the printed materials Y and Z are adhered and sealed so as to be peelable at the facing portions.

  As shown in FIGS. 9A, 9B, and 9C, the three-fold sealed letter F2 manufactured by the above-described process is a single sheet of sealed letter in which the printed materials Y and Z are enclosed. The recipient of the sealed letter F2 breaks the cut sewing machines 16 and 17 provided on the edge shown in FIGS. 9A and 9B by bending them along the edge. And the part which floated by the said fracture | rupture operation | movement can be picked and opened with a finger as the beginning of peeling. In addition, since it is connected with the leaf piece part of the small area parted by the said fracture | rupture and the 2nd leaf piece 12, and since it is pseudo-adhering with the 2nd leaf piece 12, it does not isolate | separate and become garbage.

  Moreover, the adhesion state of each leaf piece shown in the cross-sectional view of FIG. 9C is such that the portions where the pseudo adhesive film sheets G on the outer periphery of the printed materials Y and Z face each other are detachably adhered, and the printed materials Y and The part where Z and the pseudo-adhesive film sheet G are in contact is not bonded at all. Accordingly, the printed materials Y and Z can be easily taken out from the tri-fold sealed letter sheet S2 developed on the plane after opening, even though it is sealed at the time of mailing.

The present invention is not limited to the above embodiment.
In each of the above-described embodiments, as a means for opening a sealed letter, a step by a corner cut or a cut sewing machine is folded and broken, but it is not limited thereto. For example, in the case of the folded letter F1, as shown in FIGS. 10 (A) and 10 (B), the width of either the first leaf piece 21 or the second leaf piece 22 is widened, and the folded side is opened when folded. The step formed on the edge may be the beginning of peeling. Similarly, in the case of the tri-fold sealed letter F2, as shown in FIG. 11 (A), the width of the first leaf piece 31 and the third leaf piece 33 is set wider than the width of the central second leaf piece 32. The step formed in this way may be the beginning of peeling. Conversely, as shown in FIG. 11B, a step formed by making the width of the second leaf piece 32 wider than the other two leaf pieces may be used, and as shown in FIG. 11C. The both may be used in combination.

Further, in the case of a sealed letter composed of three leaf pieces, the third leaf piece may be wound in a folded form in addition to the three-fold Z-shaped cross-fold of the present embodiment.
Furthermore, there are no restrictions on the winding form of four or more leaf pieces (bellows folds, winding folds, double-fold folds, and mixed forms thereof), and any opposing leaf pieces are inseparably non-peelable or do not do anything and are free It does not matter.

  In particular, when the pseudo-adhesive medium is a pseudo-adhesive film sheet, by forming innumerable fine through-holes in the pseudo-adhesive film sheet, the originally tough film sheet can be easily broken and cannot be discarded. It is.
