Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mail form capable of concealing and transmitting a large amount of confidential information.

[0002]

2. Description of the Related Art Conventionally, a bank, a securities company, an insurance company, etc. have concealed confidential information such as balance notification, transaction notification, and contract details to a customer and mail it to an individual as a tri-fold mail form, A4. Envelopes made by folding cut paper and using an enclosing and sealing machine have been used. As shown in FIG. 7, an example of the tri-fold mail form 30 is composed of three form pieces 21 to 23 having a predetermined shape, and is folded back in a Z shape at fold lines 24 and 25. The form piece 21 is provided with an address area 21a, and the form pieces 22 and 23 are provided with print areas 22a and 23a for printing confidential information and the like to each customer. Furthermore, the adhesive layers 22b, which can be re-peeled, are formed on almost the entire surfaces of the form pieces 22 and 23 as indicated by the diagonal lines.
23b is provided, and adhesive layers 21b 'and 22b' that cannot be re-peeled are provided on the back surfaces of the form pieces 21 and 22 in the figure.
Is provided. FIG. 8 is a side view showing how the tri-fold mail form in FIG. 7 is folded back. The three-fold mail form is printed on one side in the print areas 21a to 23a, and then folded back so that the adhesive layers 21b 'and 22b' and 22b and 23b face each other at the crease lines 24 and 25, and then sealed by pressure bonding. It is stopped and it becomes a mail form. Customers who receive the tri-fold mail form,
As shown in FIG. 9, the form piece 23 can be peeled off from the corner again to open the confidential information print areas 22a and 23a.

Here, confidential information printing areas 22a and 23a
The personal information printed on is related to one subject. For example, in the case of a bank, information on various subjects such as notification of maturity of time deposit, notification of deposit and withdrawal details, notification of loan payment / balance, notification of payment details by credit, etc. However, only the information regarding one of the subjects is recorded in one triple fold 1, and the information regarding another subject is recorded in another mail form.

In addition, a letter-folded A4 cut paper,
Envelopes that use the enclosing machine are also used. Since the A4 cut paper is printed and folded, and the four sides are adhesively attached so as not to be removable again, the three sides must be torn when opening. Envelopes using the enclosing and sealing machine are those in which a form, etc. printed on an envelope prepared separately is enclosed through operations such as collating.

[0005]

However, in recent years, the amount of confidential information to be transmitted to an individual for one time has increased, and there is a problem that the space for the information printing area is insufficient in the conventional mail forms. In addition, there is a problem that a three-fold mail form with three sides sealed or an A4 cut sheet cannot be opened unless the three sides are torn, and dust is generated when opening. Further, the conventional one has a problem that even if it is opened, it is not possible to view the front and back in a single sheet. Envelopes using the enclosing and sealing machine can handle quite a lot of data, but there was a problem that the process until completion was long and complicated. The above-mentioned three-fold mail form has a problem that when opening the confidential information printing portions 22a and 23a, the form piece 23 curls outward as shown in FIG. 9 and the printed information becomes difficult to see. In general, when there are many adhesive areas on the printed surface, there is a problem that the adhesive is peeled off and adhered to the transportation surface of the printing printer, the transportation roller or the like, and the printed surface is soiled or transportation failure occurs. The present invention has been made in view of the above-mentioned problems, and can conceal and send any amount of confidential information from a small amount to a large amount, can be opened with an appropriate force, and curling does not occur at the time of opening. It is an object of the present invention to provide a mail form having a curl prevention function that can list print information in a state similar to a sheet.

[0006]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, has a continuous form in which a plurality of form pieces each having a pressure-sensitive adhesive layer that can be re-peeled on both sides are connected to each other through a crease line. Are alternately folded back in the opposite direction along the crease line and sealed by applying pressure,
Furthermore, two of the opposite form pieces are folded back along the crease line.
A mail form is characterized in that an adhesive reduction ink layer is provided at the center of at least one of the surfaces.

[0008]

According to the present invention, the length of the continuous form can be freely set according to the amount of information. In other words, for any amount of confidential information over multiple subjects, confidential information for each customer is printed in a continuous form with a length corresponding to that amount, folded back alternately at crease lines, and pressed to form a mail form easily. , Confidential information can be hidden and mailed. The mail form used in the present invention has a re-peelable adhesive layer on both sides in advance, and at least one of the two sides of the form piece that is folded back and adhered at the crease line.
An ink layer for reducing adhesive strength is provided in the center of the surface, and the two surfaces of the adhered form piece are adhered only around the form piece. Therefore, at the time of re-peeling, unlike the case of the full-face adhesion as in the case of the tri-fold mail form shown in FIG. 9, the peeling resistance is small, it can be opened with an appropriate force, and the occurrence of curling on the peeled form piece can be prevented. it can. Since the mail form according to the present invention has no curl and is very small, even if it exists, it is easy to open in the form of a long sheet, and confidential information as well as general information that has been printed in advance should be listed. You can Furthermore, since the adhesive area is reduced, the flow of continuous foam in the printer becomes smooth, and troubles such as paper jams are less likely to occur. Further, upon opening, it can be easily opened without breaking the three sides such as a tri-fold mail form with three sides sealed or A4 cut paper, and no dust is generated. The mail form does not require collation, the process is simplified, the envelope is not used, the enclosing work is omitted, and the manufacturing cost can be reduced.

Are connected via fold lines m1, m2, m3 to m (n + 1), and sprocket holes 11 and vertical perforations 12 are provided on the left and right. Information printing areas 1a to na and 1a 'to na' are formed in the central portions of the front and back of each form piece. As shown in FIG. 1, the mail form according to the present invention is cut at crease lines m1 and m (n + 1) to form a mail form 20 for an individual, folded back at crease lines m2 to mn, and crimped to each individual. Will be a sealed letter. The mail form according to the present invention prints the customer's address, sender's name, etc. in 1a and na, and confidential information in 2a to (n-1) a. General information such as contract description and advertisement may be printed in advance on the back side 1a 'to na' shown in FIG.

The continuous foam paper used in the present invention is a high-quality paper of 44 to 70 g / m ² , and its entire surface is coated with a removable adhesive. As the coating method, any known method may be used.
As shown in FIG. 1 and FIG. 2, the continuous foam form piece used in the present invention has an adhesive force-reducing ink layer at the center portions 2b to nb, 1b 'to (n-1) b every other front and back sides. 'Is provided. In this embodiment, the positions of the adhesive force reduction ink layers on the front surface and the back surface are displaced. That is, the ink layer for reducing the adhesive force is provided on one surface of one form piece. Further, unlike the present embodiment, the positions of the adhesive force reduction ink layers may be the same on the front and back sides. That is, a form having an adhesive strength-reducing ink layer on both sides and a form having no ink layer may be alternately connected. Further, although an ink amount is additionally required, an adhesive force reducing ink layer may be provided on all the form surfaces. FIG. 3 is a cross-sectional view for explaining the layer structure and the position of the adhesion-reducing ink layer in this example in more detail. The layer structure is such that the releasable pressure-sensitive adhesive layer 14 is provided on both surfaces of the high-quality paper 13 which is the base material.
And an ink layer 15 for reducing the adhesive force is provided thereon. The adhesion-reducing ink layer is provided at the same time as offset printing of the format and the general information in advance. That is, using an offset multi-color printing machine, the first unit solidly prints a transparent offset printing varnish so as to cover a predetermined area on each form surface, and then prints the format and the general information. The crease lines m1 to m (n + 1), the vertical perforation 12 and the marginal punch 11 are processed. Although the printing area of the adhesive strength-reducing ink layer depends on the size of the form piece and the adhesive strength of the adhesive, it is preferable that the adhesive area around the form piece remains in a width of 5 to 10 mm.

After outputting the information for each individual from the computer to the continuous form prepared by the above method and printing the information, both ears having the left and right marginal punches 11 are perforated 12
Disconnect from. Then, the continuous form has a crease line m1.
And m (n + 1), folded in zigzag as shown in FIG. 4, and then pressed, the pressure-sensitive adhesive layers of the opposing adhesive regions adhere to each other to form a plurality of forms as shown in FIG. Form a letter envelope. When the recipient peels the first and last form pieces of the envelope from the corners and holds both of them open to the left and right, the recipient can open the envelope as shown in FIG. it can.

The removable pressure-sensitive adhesive used in the present invention is characterized in that the pressure-sensitive adhesive layers adhere to each other and can be removed again.
Hereinafter, the pressure-sensitive adhesive used in the present invention will be described in detail. The removable pressure-sensitive adhesive used in the mail form of the present invention does not adhere even when the adhesive layer comes into contact with the high-quality paper of the base material, and does not adhere until pressure contact between the adhesive layers occurs, and it is removable again. The adhesive main agent, the adhesive strength adjusting agent, the additives and the like are mixed in the following proportions. Adhesive main agent 100 parts by weight Adhesion control agent In the case of needle-shaped substances 10-100 (preferably 10-50) parts by weight In the case of fine-grained substances 0-50 (preferably 5)
30) parts by weight When the above two substances are mixed 10 to 100 parts by weight Additive wax 0.01 to 20 parts by weight UV absorbers trace amount defoaming agent trace amount defoaming aid trace amount emulsifying component water 100 to 500 (preferably 200)
To 300) parts by weight emulsifier 0.5 to 2 parts by weight resin 1 to 50 parts by weight

[Adhesive Main Agent] The adhesive main agent is a natural rubber (N
R), esterified natural rubber, styrene butadiene rubber (SBR), chloroprene rubber, polyvinyl acetate, polymethylmethacrylate (PMMA) and the like, or a mixture thereof. In mixing these adhesive main agents, by appropriately adjusting the mixing ratio, the adhesiveness to the base material can be made higher than the adhesiveness while maintaining the self-adhesiveness between the pressure-sensitive adhesives. Preferably, a natural rubber having a high property of exhibiting self-adhesiveness between pressure-sensitive adhesives under pressure is added with polymethylmethacrylate or styrene-butadiene rubber for the purpose of enhancing the adhesiveness with a base material, that is, the anchor effect. Is mentioned. Polymethylmethacrylate is preferably used as a mixture with another adhesive main agent rather than used alone. As such an adhesive main agent, fine particles having a particle size of about 0.1 μm to 3 μm are usually used.

[Adhesive Strength Adjusting Agent] The adhesive strength adjusting agent is mixed in order to adjust the adhesive strength of the main adhesive agent, and a needle-like substance or a fine particulate substance or a mixture thereof is used. Needle-like substance As the needle-like substance, any of an inorganic substance and an organic substance may be used, as long as the shape thereof is substantially needle-like, flat, spiral,
Although it is arbitrarily selected from those having various forms such as scales, a needle-shaped substance is particularly preferable. The needle-shaped substance has an average length of 10 μm to 20 μm and an average diameter of 0.2.
It is preferably about μm to 0.5 μm. Needle-like substances
It is preferable that the pressure-sensitive adhesive be an emulsion and have an apparent specific gravity of 0.05 to 0.6 in order to reduce the sedimentation property when it is used as a coating agent. Further, in consideration of printing processing and NIP suitability, a needle-shaped substance Has an elastic modulus of 10000 kg / mm ²
It is preferably about 40,000 kg / mm ² . Examples of such needle-like substances include glass fiber, carbon fiber, P
AN-based fibers, metal crystals, metal compound crystals, and the like,
The adhesive main agent may be one that has no affinity (compatibility). A preferable acicular substance is a crystal of potassium 6-titanate (K ₂ O.6TiO ₂ ), which has no compatibility with water but an affinity and an apparent specific gravity of 0.2.
(True specific gravity = 3.3), elastic modulus 28,000 kg / mm ²
And is suitable as a pressure-sensitive adhesive component.

Finely divided substances Finely divided substances include microsilica, synthetic zeolite, activated alumina gel, calcium carbonate, zinc oxide, titanium oxide, talc, clay, kaolin, activated clay, acrylic beads, starch, cellulose, shirasu balloon and the like. The particles having a particle size of 10 mμm to 30 μm, preferably 0.5 μm to 10 μm are suitable.
Further, by adding together with the needle-shaped substance, it is possible to reduce the addition amount of the fine-grained substance and prevent the fine-grained substance from falling off.

[Additives] As additives, waxes such as polyethylene wax and carnauba wax for improving handleability, slipping property such as NIP transport performance, or blocking resistance, and ammonia for preventing deterioration are added. UV absorbers such as ethanolamine may be added. Further, as an antifoaming agent, a nonionic surfactant,
An anionic surfactant (mineral oil type) may be added, or silica or the like may be added as a defoaming aid.

[Emulsifying Component] The above-mentioned adhesive main agent, adhesive force adjusting agent, and additives are dispersed in a medium such as water and applied to a substrate in an emulsion state. When emulsifying, an emulsifier is added if necessary. As the emulsifier, oleic acid soap, potassium castor oil soap, casein, glue, gelatin and the like can be used. Further, in order to prevent secondary aggregation of the adhesive main agent when emulsified, a resin having no affinity with the adhesive main agent can be added. As this resin, a water-dispersible polymer polyester,
Thermoplastic elastomer, low molecular weight polyethylene such as low density polyethylene, ionomer, vinyl acetate-olefin copolymer and the like can be preferably used.

The coating amount of such a pressure-sensitive adhesive is 0.1 g / m ^{2 to} 10 g / m ² , preferably 1.0 g after drying.
/ M ^{2 to} 3.0 g / m ² is preferable. Within this range, it is possible to print or print on the pressure-sensitive adhesive. In this case, the ink can penetrate through the pressure-sensitive adhesive and reach the base material, and transfer of the printing layer when peeled off can be prevented.

[0018]

According to the continuous foam of the present invention, when a form piece having an adhesive region is peeled off, curling does not occur on the peeled form piece, and as shown in FIG. 6, the front and back sides are flat like a sheet. It can be listed in various states.
In addition, it is possible to conceal a large amount of confidential information that was previously impossible and send it to individuals. That is, it is possible to deal with any amount of information by controlling the number of form pieces, and personal information for several subjects can be mailed to the customer in one mail form. Examples of information transmitted by the mail form according to the present invention include a notice of withdrawal of money from a bank account, a repayment schedule for XX payments when purchasing goods by credit card, a long-term repayment plan for a loan, and a life health business. It is very versatile and has information about the contents, guidance on life health contents, taxation certificate, etc. The method for processing a continuous foam according to the present invention is required to fold and press a required number of form pieces into separate pieces, which eliminates the need for using an envelope and is low in cost. The recipient does not need to tear off the three sides of the A4 cut paper or some tri-fold postcards to open it, and various effects such as no generation of dust are exhibited.
