DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments when the present invention is applied to an overlaid letter will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of an overlap sealed letter which is an overlap adhesive sheet formed by three-folding by bonding the upper and lower sheets in a peelable manner, and FIG. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is a perspective view of an overlapped letter showing a state in which the upper and lower exposed surfaces are partially peeled, and FIG. 4 is an overlap adhesion of the upper and lower sheets before being folded in three, which is an overlapped letter sheet. FIG. 5 is a cross-sectional view taken along the line BB in FIG. 4, and FIG. 6 is a schematic diagram showing a reference example of the overlapping adhesive state between the upper and lower sheets, which are sheets for overlapping sealed letters. FIG. 7 is a schematic cross-sectional view showing an overlapped letter created by folding in three.
[0008]
First, the structure of the overlay letter will be described with reference to FIGS. The overlap sealed letter 1 is composed of two folded paper pieces 3 and 4 which are peeled and bonded with a pressure-sensitive adhesive 2 which can be peeled off after the overlapping surfaces folded at the folding perforations 8 and 9 are bonded. , 9 are overlapped so that they are located on the opposite side, and are adhered to each other with a pressure-sensitive adhesive 2 so that they can be peeled off with the pressure-sensitive adhesive 2. The various pieces of information 7 and 7a are printed and / or printed on the respective surfaces of the paper pieces 3, 4, 5 and 6. If the notification information 7 is variable information that varies depending on the addressee, it is printed. If the notification information 7 is fixed information common to all addressees, it is printed. The information displayed on the surface of the piece of paper 5 is the address information that is the variable information that is printed. 7a.
[0009]
The pressure-sensitive adhesive 2 described above can be printed and printed. For example, the pressure-sensitive adhesive 2 is non-releasable adhesive base that is pressure-sensitive and difficult to be peeled off once, and exhibits non-affinity for the adhesive base. What mix | blends a fine particle filler is suitable. The adhesive base may be a general pressure-sensitive adhesive. Specifically, natural rubber latex obtained by graft copolymerization of styrene and methyl methacrylate on natural rubber has anti-blocking property. It is suitable in terms of heat resistance and wear resistance.
[0010]
On the other hand, as the fine particle filler, for example, zinc oxide, titanium oxide, calcium carbonate, kaolin, activated clay, spherical alumina, wheat starch, silica and the like are suitable. The peel strength of the laminated adhesive surface is adjusted by the blending ratio of the fine particulate filler.
[0011]
Since the present embodiment is configured as described above, the overlap letter 1 can be used in the same manner as a normal letter in the state of FIGS. 1 and 2, and the addressee to whom this overlap letter 1 is mailed is If the overlapping surface is peeled off, the notification information 7 displayed on each overlapping surface can be visually recognized. At this time, as shown in FIG. 3, when the paper pieces 5 and 6 appearing on the upper and lower surfaces are peeled from the corresponding folding perforations 8 and 9, respectively, the lower paper pieces 3 and 4 are picked together. There is no fear, and the paper pieces 5 and 6 can be smoothly rolled up and peeled off.
[0012]
In this embodiment, when each overlapping surface of the overlapped envelope 1 is peeled off, the two folded paper sheets 3 and 4 and two paper sheets that are approximately half the size of the folded paper sheets 3 and 4 are separated. 5 and 6 are separated into four pieces of paper.
[0013]
Next, a method of creating the above-described overlapped letter 1 will be described with reference to FIGS. The sheet 11 for overlapping sealed letters for creating the superimposed sealed letter 1 can be peeled off by the pressure sensitive adhesive 2 applied to the front and back surfaces of the respective sheets 12 and 13 of the upper sheet 12 and the lower sheet 13. Bonded. Although not shown in the drawing, the overlapped sealing sheet 11 is a continuous sheet that is continuous in the vertical direction, and is provided with transfer marginal holes 16 at equal intervals on both sides in the width direction.
[0014]
The notification information 7 is printed on the front and back surfaces of the upper sheet 12 and the lower sheet 13 in advance in the case of fixed information and in the case of variable information before being superimposed and bonded. Note that the address information 7a and the notification information 7 that is variable information that are printed on the exposed surface of the superimposed sealed sheet 11 may be printed later.
[0015]
Next, in correspondence with the folding position of the overlapped envelope sheet 11, the boundary between the exposed surface and the concealed surface of the upper sheet 12 and the lower sheet 13 does not reach the other sheets 12, 13, respectively. Slits 14 and 15 are provided, and folding perforations 8 and 9 (see FIG. 2 for folding perforations 9) are provided at positions corresponding to the slits 14 and 15 of the other paper sheets 12 and 13. Thus, the upper paper 12 is divided into a paper piece 5 forming the exposed surface and the folded paper piece 4 by the slit 14, and the lower paper 13 is separated from the paper piece 6 forming the exposed surface by the slit 15. It is divided into two origami pieces 3.
[0016]
After providing the slits 14 and 15 and the folding perforations 8 and 9, as described above, the address information 7a and the notification information 7 as variable information are printed on the exposed surfaces of the upper paper 12 and the lower paper 13. Is also good.
[0017]
Then, the overlapping sealed sheet 11 is folded in a Z shape so that the slits 14 and 15 are on the outside, and a predetermined pressure which is the bonding condition of the pressure sensitive adhesive 2 is applied, and this overlapping sealed sheet 11 is applied. 2 are bonded to each other in a peelable manner, the marginal hole 16 portions at both ends in the width direction are cut and removed, and a continuous sheet is formed into a single piece to form a superimposed sealed letter 1 shown in FIGS. .
[0018]
In this folding operation, since the slits 14 and 15 correspond to the outside of the folding position, the slits 14 and 15 separate and divide the paper pieces 5 and 6 forming the exposed surface and the two folded paper pieces 4 and 3. The folding does not occur between the upper sheet 12 and the lower sheet 13.
[0019]
In the present embodiment, as described above, when each overlapping surface of the overlap letter 1 is peeled, the two folded paper pieces 3 and 4 and the two paper pieces 5 and 6 are separated. A reference example for preventing separation is shown in FIG. As shown in FIG. 6, strong adhesion is made to the peelable adhesive surface of the upper sheet 22 and the lower sheet 23 by the pressure sensitive adhesive 26 that is difficult to peel off after the strong adhesion. A part may be formed. This strongly bonded portion is located at the bottom when the upper sheet 22 and the lower sheet 23 are folded in three in the width direction, and the slits 24 and 25 that are the folded portions. In the example of FIG. 25 may be provided along the two-folded paper piece 27 side. In FIG. 6, 28 and 29 are folding perforations.
[0020]
In this way, when a strong adhesive portion is provided at a predetermined position by the pressure-sensitive adhesive 26 that is difficult to peel, as shown in FIG. Each piece of paper that forms each exposed surface, two origami pieces, and two origami pieces always have a strong adhesion part, so that even if the overlapping surfaces are peeled off, the pieces of paper are separated. Absent.
[0021]
The present invention is not limited to the implementation described above, for example, of the folding position letter sheet 1 1 superposition enough be provided only slits 14,1 5, perforations for folding 8 and 9 are not necessarily provided. Further, the superimposed sealed letter 1 may be created by folding the folded sealed letter sheet 11 in three, or by folding it in half. In this case, the created sealed letter is composed of a sheet of two origami sheets and two sheets of paper that form an exposed surface that is stacked above and below.
[0022]
