BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form used as a mail form or the like.

0002

2. Description of the Related Art Conventionally, a form that can be folded in half to form a postcard has been used for notifications of usage fees sent monthly by electric power companies and telephone companies. This form had the addressee and notification information printed on the same side, was folded back so that the printed side was on the outside, and the inside side was completely glued with re-wet glue.

[0003] This form is the minimum form necessary in view of the addressee and the amount of information to be notified, and since it can be printed on one side, it is possible to ensure matching of the addressee and the information to be notified, and it can also be printed using an NIP (non-impact printer). ) and other high-speed printers can be used for efficient processing.

[0004] On the other hand, forms that can be folded into three to form envelopes have been used for salary payment slips and the like. This form can be sealed with a band-shaped adhesive layer formed around the periphery, and opened by cutting it from the perforation. At this time, there were some that could be opened in the form of a booklet by removing the periphery in a U-shape.

[0005]

[Problem to be solved by the invention] However, in the former form, the folded inner surface is completely glued, so
could not be used.

[0006] Furthermore, in the latter type of form, the perforations and the like are cut out when the form is opened, which causes problems in that it is troublesome to handle and also generates dust after being cut out.

[0007] The purpose of the present invention is to solve the above-mentioned problems,
To provide a form that can effectively utilize the printed back side. Another object of the present invention is to provide a form that can be easily made into a booklet when peeled off.

[0008]

[Means for Solving the Problems] A form according to the present invention is composed of a main body sheet, and an adhesive sheet having an adhesive layer formed on substantially the entire surface of both sides thereof to be removable by applying pressure to the main body sheet, It is characterized in that the adhesive sheet is sandwiched between the body sheets folded back or laminated, and the sheets are brought into close contact with each other.

[0009] In this case, an adhesive layer or an adhesive layer is formed on a part of the main body sheet or the adhesive sheet, and when the main body sheet and the adhesive sheet are peeled off, , it is possible to have a configuration in which both are adhered.

0010

[Operation] According to the present invention, a main body sheet on which information is printed and an adhesive sheet coated with a pressure-sensitive adhesive are prepared separately, the adhesive sheet is sandwiched between the main sheets, and pressure is applied. Both can be brought into close contact with each other in a removable manner. Therefore, information can be written on the reverse side of the printed side by printing or the like.

[0011] Furthermore, since a part of the main body sheet and the adhesive sheet are irremovably adhered to each other when peeled off, the contents can be read or stored in the form of a booklet or the like.

0012

EXAMPLES The present invention will be described in detail below with reference to the drawings and the like. 1 to 5 are views showing embodiments of a form according to the present invention, in which FIG. 1 is a perspective view, FIG. 2 is a view showing a main body sheet, and FIG. 3 is a cross-sectional view showing an adhesive sheet. 4 is a perspective view explaining the adhesion method, and FIG. 5 is V in FIG.
FIG. 6 is an enlarged view showing the part, and FIG. 6 is a perspective view showing the peeled state.

The form 1 of this embodiment is used as a mail form for postcards, and is a combination of a main body sheet 2 and an adhesive sheet 3, as shown in FIG.

As shown in FIG. 2, the main body sheet 2 has an address printing surface 21 on the left side of the front side and a notification information printing surface 22 on the right side. This main body sheet 2 has a vertical perforation p for folding it in half approximately in the center, and horizontal perforations q for cutting it into unit forms at the top and bottom. Additionally, marginal parts r are provided on both sides of the main body sheet 2, and the marginal punch holes s allow for continuous feeding during printing, and after printing, the marginal parts r can be separated by vertical perforations t. .

[0015] The main body sheet 2 may be in the form of a sheet with good printability, and usually NIP paper or the like is used depending on the printer used, but other materials include PE, PP, etc. , PET, vinyl chloride, nonwoven fabric, etc. can be used. The size, thickness, shape, etc. of the main body sheet 2 are not particularly limited, and can be appropriately selected according to the mode of use. When used as a mail form for postcards as in this embodiment, it is preferable to use a weight and shape that allows it to be treated as a postcard under the current postal law.

Unlike conventional mail forms, etc., the main body sheet 2 is not coated with a pressure-sensitive adhesive or the like, so it will not be scratched by a roll or the like when printing with a high-speed printer such as NIP. There are no problems such as piling, which causes adhesive residue, heat resistance when a heat fixing roll is used, or blocking when stacking.

The adhesive sheet 3 is approximately half the size of the main sheet 2 when cut into unit forms (FIG. 1), and as shown in FIG.
is being formed. As the base material 31, substantially the same material as the main body sheet 21 can be used. The adhesive layer 32 is the main body sheet 2
A removable pressure-sensitive adhesive is applied to the surface. As this pressure-sensitive adhesive, natural rubber (N
R) and styrene-butadiene rubber (SBR) as the main components for adhesion,
Emulsions to which PMMA), vinyl acetate, microsilica, polymer resins, dispersions, ammonia, wax, etc. are added can be used.

In this adhesive sheet 3, the adhesive layer 32 is the base material 3.
It is coated on almost the entire surface of 1 and is used for envelopes currently in use.
Since there is no need to apply in a pattern as with folded mail forms, coating methods faster than the flexographic method such as spraying, gravure, dipping, etc. can be used. This greatly increases manufacturing speed, lowers costs, and shortens delivery times. It also eliminates the need to apply excess pressure-sensitive adhesive to forms that could otherwise be discarded due to printing errors. Reasonable.

It is preferable to store the adhesive sheet 3 in a rolled state. The reason for this is that even if some dry tack remains, it can withstand use, and since it will not be rubbed by rolls etc., it can be used even if the pile is slightly weak.

[0020] Note that the vertical perforation p on the back side of the main body sheet 2
Nearby, a line-shaped adhesive layer 23 can be formed using the adhesive used to form the adhesive layer 32. Since the adhesive layer 23 can be formed by coating using a nozzle or the like, the coating speed can be extremely high compared to the flexo method. Since the adhesive layers 23 and 32 completely adhere to each other irremovably by applying pressure, the main body sheet 2 and the adhesive sheet 3 are joined at this portion when peeled off, so that the main sheet 2 and the adhesive sheet 3 can be used in the form of a booklet.

Next, a specific manufacturing example of the form 1 will be described in more detail. First, as the main body sheet 2, a high-quality paper for NIP (FPLB-S, manufactured by Sanyo Kokusaku Pulp Co., Ltd., 70 kg base) is UV offset printed on both the front and back sides, and perforations p, q, t and In addition to forming marginal punch holes s, a line-shaped pressure-sensitive adhesive layer 23 was formed. This main body sheet 2 was made into a state in which about 2000 sheets were folded in a zigzag pattern for each unit form.

[0022] Also, as the adhesive sheet 3, the main body sheet 2
After printing necessary information on a base material 31 of similar paper by UV offset printing, horizontal perforations U are formed, and at the same time, a pressure-sensitive adhesive is applied to the front and back surfaces of the base material 31 using a gravure method. An adhesive layer 32 was formed and wound to a length of 300 m. The pressure sensitive adhesives used were mixed in the proportions shown below. NR 15-20
Part SBR 10-15
Part micro silica 5 to 10 parts Polymer resin 5 to 15 parts PMM
A Trace amount of vinyl acetate Trace amount of ammonia
trace water
65-45 copies

[0023]
Next, how to use the form 1 of this embodiment will be explained. First, the address printing surface 21 and the notification information printing surface 22 of the main body sheet 2
Then, use a printer such as NIP to print out the necessary information. Since it is printed on one side of the main body sheet 2, matching of the addressee and notification information can be ensured.

As shown in FIG. 4, the printed main body sheet 2
is folded in half from the vertical perforation p by a guide (not shown), and as shown in FIG. gap, about 80~100μ
m) to bring them into close contact under pressure. At this time, the horizontal perforations q of the main body sheet 2 and the horizontal perforations u of the adhesive sheet 2 are aligned in advance. By creating the form 1 in this manner, it can be mailed with the same postage charges as a postcard.

As shown in FIG. 6, by peeling off the main body sheet 2 and the adhesive sheet 3, the recipient can open the printed matter without damaging it and can read the printed matter. At this time, the pressure-sensitive adhesive layer 23 of the main body sheet 2 and the pressure-sensitive adhesive layer 32 of the adhesive sheet 3 are adhered to each other, so that the printed matter can be read or stored when bound into a booklet. can.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made within the scope of the present invention. I explained the example of folding the main body sheet in two, but if you fold it in three,
Two adhesive sheets may be used to bring them into close contact. Further, the paper is not limited to folding in two or three, but may be folding in four or more, and the number of printed surfaces and the printed information are not particularly limited. Furthermore, main body sheets of the same size as the adhesive sheets may be alternately stacked on top of each other.

[0027] Furthermore, the form in which information is printed may be continuous paper or cut paper, and the printer is not limited to NIP, but may also be a thermal transfer method, a dot impact printer, or the like.

Furthermore, instead of forming a pressure-sensitive adhesive layer on the main body sheet, a strong pressure-sensitive adhesive (such as NR base) may be applied in a line on the adhesive sheet side to form a booklet. To prevent unnecessary opening, a strong pressure-sensitive adhesive layer may be provided on all or part of the peripheral edge so as not to cover the area to be printed.

Furthermore, if confidential information is printed on the inside of the main body sheet or on the adhesive sheet, it can also be used as a mail form for confidential postcards. Furthermore, when printing on an adhesive sheet, printing may be performed on the adhesive layer.

[0030]

Effects of the Invention As explained in detail above, according to the present invention, it is possible to print on the back side of the printing surface of the main body sheet or on the adhesive sheet, so information can be printed on the surface that has not been used in the past. can be communicated.

[0031] Furthermore, when the main body sheet and the adhesive sheet are peeled off, since they are partially joined, it can be used in the form of a booklet without having to separate at perforations or the like.
