  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing the appearance of the concealment sheet.

  As shown in FIG. 1, the concealment sheet 10 of this embodiment is not a label base paper as in the prior art, but is a sheet in which high-quality paper (upper paper 11 and lower paper 12) of the same size are stacked and bonded together. It was produced using.

  A fold line 13 is formed at the center of the sheet. The fold line 13 is a perforation cut so as to penetrate both the upper paper 11 and the lower paper 12 so that the sheet can be easily folded and cut out. The concealment sheet 10 is divided into two regions on the left and right sides (hereinafter, the left region in the figure is referred to as “first region” and the right region is referred to as “second region”) via a folding line 13.

  Further, cut lines 14 are formed along the four peripheral edges of the sheet. The cut line 14 is a slit cut so as to penetrate only the upper paper 11 of the sheet. The outer portion of the cut line 14 can be separated, and an inverted “U” -shaped separation portion 23 is provided at the peripheral portion of the first region 21, and the peripheral portion of the second region 22 is provided at the peripheral portion. A “U” -shaped separation portion 24 is provided. An area inside the cut line 14 is an information entry field 25.

  In the present embodiment, the cut line 14 is a slit having an uncut portion, but may be a continuous slit having no uncut portion.

  FIG. 2 is a diagram illustrating the configuration of the upper paper and the lower paper constituting the concealment sheet.

  As shown in FIG. 2A, a release agent layer 31 to which a release agent is applied is provided on the back surface of the upper paper 11 only in a region outside the cut line 14. The release agent layer 31 is provided in the same manner in both regions of the separation part 23 and the separation part 24. However, a margin part 34 to which a release agent is not applied is provided in the peripheral part of the upper paper 11, the peripheral part of the folding line 13, and the peripheral part of the cut line 14, and the area corresponding to the information entry field 25 is provided. Nothing is applied.

  As the release agent, an ultraviolet curable ink containing silicone can be used. For example, “NVR OP Varnish UP-200” (T & K TOKA Corporation, product name) may be mentioned as a commercially available ink.

  As shown in FIG. 2B, the configuration of the lower paper 12 is different between the first area 21 and the second area 22. In the first area 21, an adhesive layer 32 obtained by applying an adhesive to the lower paper 12 is provided in an area corresponding to the separation portion 23, and in the second area 22, the adhesive is attached to the lower paper 12 in an area corresponding to the separation portion 24. An adhesive layer 33 to which an agent is applied is provided. In addition, an adhesive layer 32 is provided in an area corresponding to the information entry field 25 in common with the first area 21 and the second area 22. However, margins 34 to which the adhesive and the adhesive are not applied are provided at the peripheral edge of the lower paper 11, the peripheral part of the folding line 13, and the peripheral part of the cut line corresponding part.

  As the adhesive, an acrylic emulsion type adhesive generally used for paper labels is suitable, and commercially available ones include strong adhesive “SE-7001” (Showa Polymer Co., Ltd., product name). It is done. Moreover, what is necessary is just to have no stickiness after peeling, and a pressure sensitive adhesive can be used for it. Examples of commercially available pressure sensitive adhesives include natural rubber latex “A700K-09” (Regex Corporation, product name).

  FIG. 3 is a diagram illustrating a cross-sectional state of the concealment sheet.

  As shown in FIG. 3, when the concealment sheet 10 is viewed in the first region 21, the separation sheet 23 is in contact with the release agent layer 31 on the back surface of the upper paper and the adhesive layer 32 on the lower paper surface. And the lower paper 12 are detachably bonded. On the other hand, in the second region 22, pseudo-adhesion is made so that the upper paper 11 and the lower paper 12 can be peeled off by contacting the release agent layer 31 on the back side of the upper paper and the adhesive layer 33 on the lower paper surface in the separation portion 24. Has been. In the information entry field 25, the upper paper 11 and the lower paper 12 are completely bonded so that they cannot be peeled off by the adhesive layer 32. In addition, once the pseudo-adhesion surfaces of the release agent layer 31 and the adhesive layer 33 are peeled off, the adhesive force is lost, and it is difficult to re-apply.

  The concealment sheet of this embodiment is configured as described above, and the operation thereof will be described below.

  FIG. 4 is a diagram showing an example in which the concealment sheet is applied to the delivery note, and FIG. 5 is a diagram showing a cross-sectional state of the concealment sheet.

  As shown in FIG. 4A, the producer of the delivery note prints necessary items such as a destination, a product name, and a billing amount in the information entry field 25 of the upper sheet 11 with a printer. Here, since the upper paper 11 and the lower paper 12 are completely bonded by the adhesive layer 32 in both the first area 21 and the second area 22, the information entry field 25 indicates that the upper paper 11 and the lower paper 12 There is no room for air to enter between, and no flickering occurs. Moreover, since the margin part 34 which does not apply an adhesive and an adhesive agent is provided in the peripheral part of the concealment sheet | seat 10, paste does not protrude from the paper edge part of a sheet | seat. Therefore, it is excellent in transportability with a printer and good printing is possible.

  Next, the information printed in the information entry field 25 is concealed. In the method, first, the separation part 23 is peeled off according to the cut line 14 in the peripheral part of the first region 21. Since the adhesive force of the upper paper 11 is weakened by the release agent layer 31 on the back surface, only the separation part 23 can be easily peeled off. As a result, as shown in FIG. 5A, the adhesive layer 32 at the peripheral edge of the lower paper 12 is exposed.

  And as shown in FIG.4 (b), the concealment sheet | seat 10 is folded in half by the fold line 13, and the 1st area | region 21 is piled up on the 2nd area | region 22, and is bonded together. Thereby, in the peripheral part of the concealment sheet 10, as shown in FIG.5 (b), the separation parts 23 and 24 are adhere | attached by the adhesive layer 32 on the lower paper surface, and the information entry column 25 is concealed and notified. it can.

  On the other hand, the recipient of the delivery note opens as follows. That is, as shown in FIG. 4C, the upper sheet 11 and the lower sheet 12 of the bonded concealment sheet 10 are peeled off. Here, the separation portions 23 and 24 are bonded to each other at the peripheral portion of the concealment sheet 10, but the adhesive force between the upper paper 11 and the adhesive layer 32 is between the release agent layer 31 and the adhesive layer 33. It is stronger than the adhesive strength between them, and it is desirable to break the paper if it is forced to peel off. Further, a cut line 14 for separating the separation portion 24 is formed in the second region 22. Therefore, as shown in FIG. 5C, the separation part 24 in the second region 22 is separated from the upper paper 11 while being adhered to the separation part 21 in the first region 21, and the release agent layer 31 and the adhesive layer 33 are separated. It peels through the pseudo-adhesive surface between the two.

  Therefore, as shown in FIG. 4D, when the upper sheet 11 and the lower sheet 12 of the concealment sheet 10 are peeled to make a spread state, the concealed information entry column 25 appears, and the printed destination, Necessary items such as product name and billing amount can be confirmed. Thus, according to the concealment sheet 10 of the present embodiment, it is not necessary to cut perforations as in the prior art at the time of opening, and it is easy to use because it can be opened by a simple operation. In addition, since the separation unit 23 and the information entry column 25 and the separation unit 24 and the information entry column 25 are separated through the cut line 14, the information entry column 25 is not accidentally broken at the time of opening, and the reliable opening. Work can be done.

  Further, when the concealment sheet 10 is opened, it is peeled off through a pseudo-adhesive surface between the release agent layer 31 and the adhesive layer 33, and after peeling, the adhesive layer 33 does not have any stickiness and is bonded again. It has become difficult. As described above, by adopting a pseudo-adhesive structure for the separation portion 24 provided in the second region 22, it is possible to detect the fact that it has been opened by preventing it from being attached again after being peeled off.

  In this embodiment, in the information entry field 25, the upper paper 11 and the lower paper 12 are bonded together with the adhesive layer 32 so that they cannot be peeled off. However, as shown in FIG. It is also possible to adhere the upper paper 11 and the lower paper 12 so as not to be peeled off by the adhesive layer 33 thus obtained. Further, when the information entry field 25 is bonded, the pressure-sensitive adhesive layer 32 and the adhesive layer 33 may be applied not on the surface of the lower paper 12 but on the back surface of the upper paper 11.

  Next, another embodiment of the present invention will be described. In the above-described embodiment, the information entry field 25 has a specification that cannot be peeled, but instead, the information entry field 25 can also have a peelable specification.

  As shown in FIG. 7, in the concealment sheet 10 of this embodiment, a release agent layer 31 is applied to the back surface of the upper paper 11 in the information entry field 25, and the surface of the lower paper 12 opposite to this is applied to the surface of the lower paper 12. An adhesive layer 33 is applied. Thereby, in the information entry column 25, the upper paper 11 and the lower paper 12 have a structure in which they are pseudo-bonded so as to be peeled at the boundary surface between the release agent layer 31 and the adhesive layer 33. About another structure, it is the same as that of embodiment mentioned above, and what has already illustrated a peeling agent and an adhesive agent can be used.

  According to this concealment sheet 10, it is possible to perform concealment work and opening work basically in the same manner as the method described in FIG. 4, but in this embodiment, after opening as shown in FIG. Only the part of the information entry field 25 can be peeled off from the lower sheet 12. Further, the release agent layer 31 and the adhesive layer 33 are configured to be seen through by applying a colorless and transparent release agent and an adhesive, for example. Therefore, when the information entry field 25 is peeled off, the information A such as an advertisement printed in advance on the back surface of the information entry field 25 or the front surface of the lower paper 12 can be seen as shown in FIG. 10 can increase the amount of information posted. Further, by peeling off the information entry field 25 from the lower paper 12, the information entry field 25 becomes thinner and its size is reduced, so that there is an advantage that the information entry field 25 can be stored compactly without being bulky.

  Here, for example, a structure as shown in FIG. 9 can be adopted as a specification for pseudo-adhering the information entry field 25 in a peelable manner.

  In the structure shown in FIG. 9A, the release agent layer 31 is applied to the entire back surface of the upper paper 11 in the information entry field 25, and the adhesive layer 33 is applied to the surface of the lower paper 12 opposite thereto. A pattern is applied partially and adhered. On the other hand, in the structure shown in FIG. 9B, the pressure-sensitive adhesive layer 35 is applied to the entire back surface of the upper paper 11 and the front surface of the lower paper 12 for the separation portion 24 and the information entry field 25, respectively. Are pressed against each other. According to these pseudo-adhesive structures, since the adhesive force between the upper paper 11 and the lower paper 12 is weakened, the information entry column 25 can be peeled off with a lighter force, and the back side of the information entry column 25 can be peeled off. It is suitable for storage.

  Furthermore, as another pseudo-adhesion structure, for example, a structure as shown in FIG. 10 may be adopted.

  The structure shown in FIG. 10 (a) uses delamination of a release agent, and a pressure-sensitive adhesive layer 32 is applied to the surface of the lower paper 11 for the separation portion 24 and the information entry column 25, and a cation is formed thereon. A delamination agent layer 36 coated with polymerized silicone is provided, and a back surface of the upper paper 11 is provided with a curing inhibitor layer 37 containing an alkaline substance that prevents polymerization of the cationically polymerized silicone. According to this structure, since the alkaline substance constituting the curing inhibitor layer 37 permeates and the delamination agent layer 36 is kept in an uncured state, the uncured delamination agent layer 36 at the time of delamination is shown in FIG. It is possible to peel off the information entry field 25 from the lower paper 12 by delamination at the portion indicated by and remaining on the adhesive layer 32.

  Further, the structure shown in FIG. 10B utilizes cohesive failure of the adhesive, and the cohesive force is weak on the back surface of the upper paper 11 or the surface of the lower paper 12 for the portions of the separation portion 24 and the information entry column 25. A cohesive fracture adhesive layer 38 coated with an adhesive is provided and bonded. As such an adhesive, for example, “QY 550DWT” (Queu Kasei Co., Ltd., product name) can be cited. According to this structure, since the cohesive force of the adhesive is weak, the cohesive failure adhesive layer 38 itself causes cohesive failure at a portion indicated by C in the drawing, and the information entry column 25 is peeled off from the lower sheet 12. Can do.

  In addition, about each embodiment mentioned above, in order to make it easy to peel at the time of opening, you may employ | adopt a structure as shown in FIG. 11 and FIG. That is, the concealment sheet 10 shown in the figure is obtained by extending the right end portion of the second region 22 and connecting the knob allowances 26. Further, a cut line 14 is formed at the boundary between the second region 22 and the picking allowance 26, and the cut line 14 is a slit obtained by cutting only the upper paper 11. Other configurations are the same as those of the above-described embodiment.

  According to the concealment sheet 10, the tab allowance 26 is left when the sheet is folded in two, and if the tab allowance 26 is picked and peeled off, the upper paper 11 and the lower paper 12 can be more easily peeled off. Can be opened.
