Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention conceals the individual information by printing individual information on a predetermined area of a plurality of connected form pieces and folding the plurality of form pieces to temporarily adhere them. It is related to the form to be done.

[0002]

2. Description of the Related Art Heretofore, forms capable of temporarily hiding individual information have been widely used for mail forms and the like. This form is composed of a plurality of form pieces provided with an adhesive layer at a predetermined position. Individual information such as confidential information is printed on these form pieces, and the form pieces are folded and adhered to form a predetermined form,
Individual information is temporarily hidden.

The recipient of this form can peel off the adhered form piece and see the individual information. In this way, the form piece is in close contact with the adhesive layer until it is delivered to the recipient, so the confidentiality of the individual information can be enhanced.

[0004]

However, the surface adhered by the adhesive layer (hereinafter referred to as the "adhesion surface") is applied with a strong pressure after peeling, or is re-adhered by using a commercially available temporary adhesive or the like. By doing so, there was a thing that seemed to be closely attached in appearance. Therefore, if a third party maliciously opens the package, re-contacts it after viewing the individual information, the recipient cannot determine whether the contact surface was previously opened.

From the experimental results, a general length of 140 m
In postcards of m and 100 mm in width, if the adhesive force (peeling force) of the contact surface is 40 g / 25 mm or more, the contact surface will be naturally peeled off during mailing (hereinafter referred to as "natural peeling"). Can be prevented. However, if the adhesive force is set higher than necessary, peeling becomes difficult, and further, the adhered surface may not be peeled cleanly in some cases.

Therefore, in practice, depending on the quality of the paper, the adhesive strength is 15 g because it is easy to peel off the contact surface.
/ 25 mm is used. Even with such an adhesive strength, it is rare that the contact surface peels off during mailing. However, if there is something that causes the adhesive surface to peel off during the mailing process, the form with the adhesive surface peeled off will be given to the recipient. You will lose the reliability of the form.

From the above, a form is demanded which can prevent spontaneous peeling of the contact surface and can determine whether or not the contact surface has been previously peeled off. Proposed separately.

FIG. 13 is a plan view showing a configuration of an example in which a form capable of discriminating whether or not the contact surface has been peeled off is applied to a mail form. In FIG. 13, only the front surface is shown and the back surface is omitted. The form 1 is composed of three form pieces 2 to 4. Connection parts 5 and 6 are provided between the form pieces 2 and 3 and between the form pieces 3 and 4, and the form pieces 2 to 4 can be folded back from the connection parts 5 and 6. A large number of this form 1 are connected in the vertical direction in the figure (the form 1 connected in the vertical direction is indicated by a two-dot chain line in the figure), and are substantially bellows-shaped at the positions of the connecting parts 1a and 1b. It is folded.

On the left side of the form piece 2 and the right side of the form piece 4, sprocket holes 2a opened at predetermined intervals, respectively.
And marginal portions 2A and 4A having the portions 4a formed therein are provided. The sprocket holes 2a and 4a are engaged with a document transport unit of a printer (not shown) for sequentially transporting the document 1.

Information such as a company name is printed in advance on the front side of the form piece 2, and an information recording area 2c is provided in which individual information such as the name of the recipient is printed by the printer. Further, the form pieces 3 and 4 are preprinted with common information, and further provided with information recording areas 3c and 4c in which individual information such as confidential information is printed by the printer.

On the right outer edge of the form piece 4 in the drawing, four separating pieces 4B having perforations formed in a substantially square shape are formed.
When an external force of a predetermined force or more acts on the separation piece 4B, the perforation is cut and the separation piece 4B is separated from the form piece 4. Further, an adhesive layer 4e is provided in the area of each separation piece 4B. A pressure sensitive adhesive or the like is used for the adhesive layer 4e. For example, for pressure sensitive adhesives, NR
A material in which (natural rubber) is used as a main component and acrylic resin or silica is added is used.

Next, a process of forming a mail form from the form 1 will be described. In FIG. 13, first, the recipient name and individual information are printed by a printer (not shown) in the information recording areas 2c to 4c of the form pieces 2 to 4 of the form 1. Next, the connecting portions 5 and 6 of the form 1 are folded back.

In FIG. 13, the connecting portion 6 of the form 1 is folded back so that the information recording areas 3c and 4c overlap each other.
As a result, the adhesive layer 4e and the paper surface of the form piece 3 overlap.
Further, the connecting portion 5 is folded back so that the back surfaces of the form pieces 2 and 3 overlap each other.

When this is pressed, the form pieces 2 and 3 are strongly adhered (non-separable) by an adhesive layer (not shown) provided on the form pieces 2 and / or 3. Further, the form pieces 3 and 4 are strongly adhered by the adhesive layer 4e. As a result, the information recording areas 3c and 4c of the form pieces 3 and 4 are hidden.

Next, the connecting portions 1a and 1b of the form 1 in which the connecting portions 5 and 6 are folded are cut. Further, the marginal parts 2A and 4A provided at both ends of the form 1 are cut. As a result, a mail form separated from the form 1 for each recipient is formed. FIG. 14 is a perspective view showing the mail form 10 formed from the form 1.

FIG. 15 is a perspective view showing a state in which the form pieces 3 and 4 of the mail form 10 of FIG. 14 are opened. The separating force for separating the adhered adhesive layer 4e and the form piece 3 and the separating force for separating the adhesive layer 4e and the separating piece 4B of the form piece 4 are the cutting force with which the separating piece 4B is cut from the form piece 4. Is set stronger than. Therefore, when the adhered form pieces 3 and 4 are opened, the adhesive layer 4e and the form piece 3 and the adhesive layer 4e and the separating piece 4B are not separated, and the separating piece 4 is not separated.
B is cut from the form piece 4. As a result, the form pieces 3 and 4 are opened. That is, as shown in FIG. 15, the form pieces 3 and 4 are unsealed in a state where the separation piece 4B is adhered to the form piece 3. When opened, the form piece 4 is separated into 4 pieces.
The opening portion 4D is formed by separating B.

The recipient of the mail form 10 is the form piece 3.
The individual information printed in the information recording areas 3c and 4c of the form pieces 3 and 4 can be seen by opening the boxes 4 and 4. Further, the separation of the separation piece 4B from the form piece 4 indicates that the form pieces 3 and 4 are opened for the first time, and thus the recipient may determine that the individual information is not known to others. it can. Further, when the separation piece 4B has already been separated, it can be determined that it has been opened by another person with the intention of opening it. In this way, it is possible to know whether or not the mail form has been previously opened depending on whether or not the separation piece 4B is separated from the form piece 4. Also, the adhesive layer 4
Since the portion bonded by e is not peeled off, the adhesive layer 4e
The adhesive force of can be set to a large value, and spontaneous peeling can be prevented.

However, in the above-mentioned form 1, the separation piece 4B is used.
Depending on the formation position and form of the opening, or the opening method (opening speed, opening force, opening direction, etc. at the time of opening) of the person who opens the bag, there is a possibility that the unsealing will be defective.

FIG. 16 is a perspective view showing an example of the mail form 10 when the opening fails. As shown in FIG. 16, when the mail form 10 is opened, all the perforations of the separation piece 4B may not be cut and the peripheral part thereof may be damaged. As a result, a part of the information recording area 4c of the form piece 4 is damaged, and it becomes impossible to read a part of the information recorded in the information recording area 4c after opening.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to prevent spontaneous peeling, to know whether the contact surface has been previously opened, and how to open it. It is an object of the present invention to provide a form that can satisfactorily open the contact surface of the form piece without depending on.

[0021]

In order to achieve the above-mentioned object, a first solution of a form according to the present invention is a first form piece (24) and a second form piece (3) connected to each other. Individual information is recorded on at least one surface of the first form piece, and the connecting portion between the first form piece and the second form piece is folded back to bring the first form piece and the second form piece into close contact with each other. A form (20) for hiding the individual information according to
Is provided in a predetermined area near the outer peripheral portion of the form piece of
Adhesive layer (7) for adhering the second form piece to the second form piece.
a) and the peripheral area of the area where the adhesive layer of the first form piece is provided or the area of the second form piece that is scheduled to adhere to the adhesive layer, or a part of the range in the vicinity thereof. A notched first notch portion (7b or 7c),
The first cutout portion is formed in a region where the adhesive layer is provided in the form piece in which the first cutout portion is formed, or in a peripheral portion of the area to be adhered or a part of the vicinity thereof. In order to include at least a part of the range other than the above range, the first cutout part is opposite to the first cutout part with the adhesive layer interposed therebetween.
On the opposite side, the first cutout portion and the second cutout portion (7c or 7b) cut out at a predetermined interval are provided, and the first form piece and the second form piece are provided. The position where the first cutout portion is expected to be broken when the piece is opened (7b-1,
The extension line extending from 7b-2 or 7c-1, 7c-2) in the unsealing planned direction at the time of unsealing has the second notch portion or the first and second notch portions formed therein. It is characterized by intersecting the outer edge of the form piece.

A second solving means for the form is characterized in that at least one end of the first cutout portion is directed to at least one of the planned opening directions.

[0023]

In the first form solving means, the first form piece and the second form piece are strongly adhered by the adhesive layer. When the adhered first and second form pieces are opened,
The adhesive layer and the first form piece are not separated from each other, and the adhesive layer and the second form piece are not separated, and a tear is generated in the opening direction from the position where the first cut portion is expected to be damaged. This rift intersects the second notch. As a result, the region where the adhesive layer is provided is separated from the form piece by the first and second cutouts and the slit, and the first form piece and the second form piece are opened. Therefore, the area including the adhesive layer can be separated from the form piece to open the first form piece and the second form piece without damaging the first and second information recording areas.

In the second form solving means, when opening the first form piece and the second form piece, a tear is made from the end of the first cutout portion in a direction substantially the same as the directing direction. Occur. Therefore, the shape of the first cutout portion can be simplified.

FIG. 4 is a plan view showing the mail form 30 formed from the form 20 of FIG. FIG. 4 illustrates the back side of the form piece 24 so that it can be seen. The mail form 30 of FIG. 4 is opened by peeling off the closely attached form pieces 3 and 24. In this unsealing, as shown in FIG. 4, three unscheduled unsealing directions of A1 direction (rightward in the drawing), A2 direction (upper right direction in the drawing), and A3 direction (lower right direction in the drawing) are conceivable. Below, mail form 30
Description will be made on the situation when the is opened in the A1 to A3 directions.

First, in FIG. 4, when opened in the A1 direction,
This unsealing force acts on the adhesive layer 7a and the end portion 7b-2 of the cut portion 7b. At this time, the separating force for separating the adhesive layer 7a and the form piece 3 and the adhesive layer 7a and the form piece 24 is set to be stronger than the cutting force for cutting the form piece 24. Therefore, the adhesive layer 7a, the form piece 3, and the adhesive layer 7
A and the form piece 24 are not separated from each other, and a tear in the direction A1 is generated from the end portion 7b-2 of the cut portion 7b. This rift advances in the A1 direction and intersects with the cut portion 7c.

Further, when the rift generated from the end portion 7b-2 of the cut portion 7b progresses in the direction A1 in the figure and reaches a point above the other end portion 7b-1, at the same time, the other end portion 7b-1.
A crack is generated in the direction A1 in the figure. This rift is
Similar to the rift, it advances in the direction A1 in the figure and intersects with the cut portion 7c.

Due to the above action, the cutouts 7b and 7c,
The area including the area where the adhesive layer 7a is provided is separated from the form piece 24 by the rift from the end portions 7b-1 and 7b-2 of the cut portion 7b in the A1 direction. By this separation, the adhesive force between the form pieces 3 and 24 becomes only the adhesive force by the adhesive layer, and the form pieces 3 and 24 are opened.

FIG. 5 is a perspective view showing the mail form 30 thus opened. An area (hatched portion in the drawing) of the form piece 24 including the adhesive layer 7a is opened, and this portion is adhered to the form piece 3 side. Therefore, the tear that occurs when the mail form 30 is opened is notched 7
When it intersects with c, it does not proceed further inward, so that the information recording areas 3c and 4c are not damaged and the form piece 3 is not damaged.
And 24 can be opened.

Next, in FIG. 4, when it is opened in the direction A2 in the figure, in the lower separating portion 7, a tear is made in the direction A2 in the figure from the end portions 7b-1 and 7b-2 of the cut portion 7b at the same time. Occurs. The crevice intersects the notch 7c, and the notches 7b, 7c and the crevice separate the region including the adhesive layer 7a from the form piece 24. Further, in the upper separating portion 7, first, the cut portion 7b is formed.
A crack in the direction A2 is generated from the end portion 7b-2, and the crack intersects the cut portion 7c. Next, tears occur in the direction A2 in the drawing at the end 7b-1 of the cut portion 7b and the end 7c-1 of the cut portion 7c, and these tears intersect the upper side of the form piece 24. As a result, the area including the adhesive layer 7a is separated from the form piece 24.

FIG. 6 is a perspective view showing the mail form 30 thus opened. As shown in FIG.
The rift generated from the notches 7b and 7c does not proceed inside the information recording area 4c. Therefore, the form pieces 3 and 24 can be opened without damaging the information recording areas 3c and 4c.

Incidentally, in the unsealing in the direction A2 in FIG. 4, depending on the unsealing method, a tear may not occur at the end 7b-2 of the notch 7b of the upper separating part 7. At this time, one end portion 7 of the cut portion 7c (upper side) in FIG.
A cleft in the direction opposite to the A2 direction in the figure occurs from c-2,
This rift intersects the left side of the form piece 24 in the drawing. Further, when the unsealing force is applied, the other end 7c of the notch 7c
A rupture occurs in the direction A2 in the figure from -1, and the crevice intersects the upper side of the form piece 24 in the figure. That is, no tear is generated in the cut portion 7b. As a result, a substantially triangular area including the tears from both ends 7c-1 and 7c-2 of the cut portion 7c and the adhesive layer 7a formed by the upper and left sides of the form piece 24 is separated from the form piece 24. Even if separated in this way, the information recording areas 3c and 4c are not damaged.

Next, when opened in the A3 direction in FIG. 4, both ends 7b-1 and 7b- of the cut portion 7b of the upper separating portion 7 are acted by the action opposite to the action at the time of opening in the A2 direction.
A tear is generated from 2 to the A3 direction, and this tear intersects the cut portion 7c, and the region including the adhesive layer 7a is the form piece 2
Separated from 4.

Further, the lower separating portion 7 has a notch portion 7b.
A rift in the A3 direction is generated from the end portion 7b-2, and the rift intersects the cut portion 7c. Further, the end portion 7b-1 of the cut portion 7b and the end portion 7c- of the cut portion 7c.
A rift in the A3 direction is generated from 1 and the rift intersects with the lower side of the form piece 24. As a result, the area including the adhesive layer 7a is separated from the form piece 24.

FIG. 7 shows the mail form 3 in this way.
It is a perspective view which shows a mode when 0 is opened. As in the case of opening in the directions A1 and A2 in FIG. 4, the form pieces 3 and 24 are not damaged to the information recording areas 3c and 4c.
And can be opened.

Incidentally, in the opening in the A3 direction in FIG. 4, similar to the opening in the A2 direction in FIG. 4, there is a case where no tear is generated in the cut portion 7b of the lower separating portion 7. At this time, in FIG. 4, from one end portion 7c-2 of the cut portion 7c to A
A tear is generated in the direction opposite to the three directions and intersects the left side of the form piece 24 in FIG. Further, the other end portion 7c of the cut portion 7c
A tear in the A3 direction occurs from -1 and intersects with the lower side of the form piece 24 in FIG. That is, a substantially triangular area including the tears from both ends 7c-1 and 7c-2 of the cut portion 7c and the adhesive layer 7a by the left side and the lower side of the form piece 24 is separated from the form piece 24.

In opening the mail form 30 shown in FIG. 4, the information recording areas 3c and 4c can be opened without damage even if the mail is opened in any of the directions A1 to A3 in FIG. In FIG. 4, the mail form 30
If the lower side is opened in the A2 direction and the upper side is opened in the A3 direction, it can be opened most efficiently. Therefore,
Opening direction (A2 and A
It is preferable to clearly indicate (3 directions).

FIG. 8 is a perspective view showing the structure of another embodiment of the separating portion 7. FIG. 8 shows an example formed on the lower left end of the form piece. In (a) of the figure, the adhesive layer 7a is formed in a substantially quadrangular shape, and the cutouts 7b and 7c are formed in the vicinity of the two sides of the adhesive layer 7a so as to surround the two sides. In the figure (b), the adhesive layer 7a is formed in a substantially bow shape, and the cutouts 7b and 7c are formed near the arc-shaped outer peripheral portion and the linear portion of the adhesive layer 7a, respectively. In (c) of the figure, the adhesive layer 7a is formed in a substantially isosceles triangle shape, the cut portion 7b is formed so as to surround the vicinity of the equilateral side, and the cut portion 7c is formed in the vicinity of the bottom side. In (d) of the figure, the adhesive layer 7a is formed in a substantially triangular shape, and one side thereof is formed substantially parallel to the lower side of the form piece. The other configuration is similar to that of FIG. In addition,
In the example shown in FIG. 8, the cut portions 7b and 7c are all formed in the vicinity of the adhesive layer 7a, but the cut portions 7b and 7c may be formed so as to model the peripheral portion of the adhesive layer 7a.

FIG. 9 shows the mail form 30 shown in FIG.
It is a top view which shows the modification of. In FIG. 4, the upper and lower separating portions 7 are formed symmetrically, but FIG.
The mail form 30A includes the upper and lower separating parts 7
It shows an example in which is formed in the same direction. In this way, the separating portion 7 is formed, and the opening direction (arrow portion in the figure) is opened on the form piece 24.
By displaying, it becomes possible to efficiently separate and open the region including the adhesive layer 7a. Further, it is preferable that a grip portion 24a is formed by cutting off the lower left end portion of the form piece 24, and further, an opening start position such as "Please open from here" is displayed to facilitate opening.

FIG. 10 is a plan view showing still another modification of the mail form 30. The mail form 30B in FIG. 10 is an example in which only one separating unit 7 is formed near the center of the outer peripheral portion of the left side of the form piece 24. in this way,
The number of the separating portions 7 is not limited to two, and may be one, or three or more (for example, the separating portion 7 of FIG. 4 or 9 and the separating portion 7 of FIG. 10 may be formed simultaneously). . It should be noted that the cutout portions 7b and 7c are similar to the separation portion 7 in FIG.
With the above, when the adhesive layer 7a is formed so as to surround the vicinity thereof, and at the same time, the formation range of the cutout portions 7b and 7c is set to overlap, the cut portion 7 is surely opened at the time of opening.
It is possible to intersect the crevice generated from b with the notch 7c.

FIG. 11 is a plan view showing the configuration of a modified example of the form 20 shown in FIG. In the form 20 of FIG. 1, the separation part 7 is formed on the form piece 24, but as in the form 20A shown in FIG. 11A, the adhesive layer 7a is formed on the form piece 3A and the cut portions 7b, 7c are formed. Only the form piece 24 may be formed.

Further, as in the form 20B shown in FIG. 11 (b), the separating portion 7 is formed on the form piece 24, and when the connecting portion 6 is folded back, the form piece is adhered to the adhesive layer 7a. An adhesive layer 7a may be provided on the 3A side. This allows
It is possible to further improve the adhesive strength between the form pieces 3 and 24.

FIG. 12 shows the structure of still another embodiment of the separating portion 7, which is a modification of FIG. 8 (c). The separating portion 7 of FIG. 12 differs from the separating portion 7 of FIG. 8C only in the shape of the cut portion 7b. That is, both ends 7b-1 and 7b-2 of the cut portion 7b are oriented in the direction opposite to the direction in which the cut portion 7c is formed. The cut portion 7b described in the embodiment is
Although tears were generated from the ends at the time of opening, both ends 7b-1 and 7b- were formed in the cut portion 7b shown in FIG.
No tear is generated from No. 2, and a tear at the time of opening is generated from 7b-3 and 7b-4 in the figure. That is, the notch 7
If the vicinity of the end of b is not a straight line or a curved line, the position where a tear occurs when opening the notch 7b is the vicinity of the end of the notch 7b where the change in curvature is the largest. Is common. In FIG. 12, when it is opened in the direction A4 in the drawing,
A fissure is generated in the A4 direction from the b-3 and 7b-4 parts, and the fissure advances to intersect the cut portion 7c.

Although one embodiment of the form according to the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the gist of the present invention. . For example, the form 20 is composed of three form pieces, but it can also be applied to the case of simply adhering two form pieces, or to the case of adhering four or more form pieces. it can.

The material of the form 20, the adhesive layer, the adhesive strength of the adhesive layer 7a, the dimensions Z1 to Z5 of the form 20 of FIG. 1, and FIG.
The respective dimensions Z11 to Z20 of the separation part 7 are the preferable numerical values for carrying out the present invention, and the numerical values are not limited in the present invention.

Although the form 20 is applied to the mail form, the form 20 is not limited to this, and can be applied to various forms such as a bag-making form for forming a salary bag.

[0055]

As described above, according to the form described in claim 1, the first cutout portion and the second cutout portion are formed to separate the region including the adhesive layer from the form piece. Since the contact surface is opened by means of the opening, the contact surface of the form piece can be opened satisfactorily without depending on the opening method, and damage to the information recorded on the form piece can be prevented. Further, since a tear is generated in the form piece to open the contact surface, the adhesive strength of the adhesive layer can be set to be strong, and spontaneous peeling of the contact surface of the form piece can be prevented. Furthermore, since the contact surface cannot be opened unless at least the area bonded by this adhesive layer is separated, it is possible to leave an opening mark by peeling the contact surface,
It is possible to know for sure whether the package has been opened.

According to the form described in claim 2, since the tear is generated from the end of the first cutout portion in substantially the same direction as the directing direction, the shape of the first cutout portion is formed. Can be simplified. Further, the directions of the tears can be made uniform, and the information recording area of the form piece can be more reliably prevented from being damaged.
