Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a concealed information carrying body such as a simple concealed envelope that can conceal and send out a notice.

[0002]

[Problems to be solved by the invention]

 Usage statements, invoices, notices of deposit expiration, payment notices for various taxes, etc. must be transmitted only to the confidential person, but the information must be printed on each envelope. Since the work efficiency is not good if the seal is used, and the postage cost increases with the envelope, the address of the shipping address etc. is printed on one side of the postcard size paper for the purpose of automating the sending of documents etc. In addition, a concealed postcard has been used in which predetermined information is printed on the other side, and a separate laminated paper having a seal layer formed on the entire surface is adhered on the other side in order to conceal this information.

However, the conventional concealed postcard has a problem that the cost is still high because a separate bonded paper is attached. Therefore, as a solution to such a problem, as shown in FIG. 4, a single sheet 11 consisting of a left sheet 12 and a right sheet 13 in which two postcards are continuously arranged in the horizontal direction is folded, and the left sheet is folded. The information 14 is printed on the bonding surface 12A of 12 and the destination address 15 and the like are printed on the outer surface 12B, and the adhesive 16 is applied to the entire bonding surface 13A of the right side paper 13 as necessary. A material in which a release layer (not shown) made of a synthetic resin or the like is formed on the bonding surface 12A of the left paper surface 12 and both are bonded to each other has been used.

However, in such a foldable concealed postcard, the paper 11 is thinner than a normal postcard so that the paper surface 11 does not become excessively thick. Since the adhesive 16 is applied to the entire surface 13A of the right paper 13, the right paper 13, which is the side to be peeled off, is likely to curl. Because of the strong pull, the curled form will remain. If the curl remains on the paper surface 11, for example, when the concealed postcard is directly transferred to a reader such as an OCR as a transfer paper, there is a problem that paper feeding becomes difficult. Further, the adhesive 16 is applied to the entire surface of the bonding surface 13A of the right side paper 13 and a release layer is formed on the entire surface of the bonding surface 12A of the left side paper 12 as necessary. 13A had a problem in that the ink was not easily adaptable and was not always suitable for providing a column for the recipient to write with a pen or the like.

[0005] In view of this, it is necessary to fold a sheet of paper such as postcards, which is continuous in the horizontal direction, into two folds to form an adhesive layer only on the peripheral edge, bond them in a bag binding shape, and cut off the peripheral edge. Simple concealed envelopes with perforations to print information on the inner side of the envelope paper itself are also used, but such simple concealed envelopes are not only time-consuming due to too many manufacturing steps, There is a problem that it is difficult to use a reader such as an OCR if the adhesive portion is not removed cleanly at the perforation.

The present invention has been made in view of the above problems, and provides a concealed information holding body such as a simple concealed envelope which does not require sewing, which prevents curling of a paper surface on which an adhesive is applied. The purpose is to do.

[0007]

[Means for Solving the Problems]

 The concealed information-carrying body according to claim 1 of the present invention is provided with at least a pair of peelable bonding surfaces on a continuous paper surface, and forming an adhesive layer on at least one of the bonding surfaces. The information and the like are normally carried out by holding the information and the like, and the information is usually concealed and the information is visible when the bonding surface is peeled off. The adhesive layer is intermittently provided at the periphery of the bonding surface. It is provided in a special way. For this reason, since the adhesive layer is partially formed on the periphery of the bonding surface, the adhesive layer does not curl on the paper surface due to the adhesive layer, and the adhesive layer is easily peeled off. It does not damage the paper when peeling off on the bonding surface. In addition, since no adhesive is applied to the center of the bonding surface, it is easy to write with a pen or the like without impairing the familiarity of the ink, and it is easy to provide a description column.

[0008] A concealed information carrying body according to a second aspect of the present invention uses the natural or synthetic rubber-based paste having a temporary adhesive property as the adhesive in the first aspect. For this reason, it is possible to bond the bonding surfaces with an appropriate bonding strength.

A concealed information possessing body according to a third aspect is the concealed information carrying body according to the first or second aspect, wherein the adhesive layer is provided with a width of 2.5 to 3.5 mm and a length of 40 to 80 mm. is there. Therefore, even if the bonding surfaces are firmly adhered, the paper surface is not damaged, the paper surface is easily peeled, and the paper surface is not curled.

According to a fourth aspect of the present invention, there is provided the concealed information holding body according to the third aspect, wherein an adhesive layer is formed on both surfaces of the bonding surface, and the adhesive layers on both bonding surfaces do not overlap each other. Thus, it is formed asymmetrically in the peripheral portion in the left-right direction and the up-down direction, and is staggered so that air can easily escape. As a result, the adhesive layers do not overlap with each other to cause blocking, and since the adhesive layers are staggered, an escape route for the air from the inner portion is secured at the time of bonding. The layers are not peeled off.

Further, the concealed information holding body according to claim 5 is the one according to claim 3 or 4, wherein the adhesive layer has an adhesive strength of 8 to 22 N / m at 180 ° peel force. is there. Therefore, the surface of the bonded paper is not particularly damaged and is easily peeled off, and the paper is not curled.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIGS. 1 to 3 show a simple concealed envelope as a concealed information holding body according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a continuous paper surface having a width of two envelopes in the horizontal direction. The paper surface 1 is divided into a left side paper surface 2 as a front side and a right side paper surface 3 as a back side, and one side surface of both the paper surfaces 2 and 3 is a bonding surface 2A, 3A, respectively. The mating surfaces 2A and 3A, that is, the inner surface side of the envelope are directly printed surfaces of the concealment information 4, respectively. Adhesive layers 5 and 5A made of a heat-sensitive or pressure-sensitive adhesive are intermittently formed on the periphery of the left paper surface 2 and the right paper surface 3. The adhesive layers 5 and 5A are formed asymmetrically on the peripheral portion so as to be slightly shifted in the left-right direction and the vertical direction so as not to overlap with each other, specifically, to be shifted by almost the width of the adhesive layers 5 and 5A. It is staggered so that air can escape easily. The adhesive layers 5, 5A are hatched in the plan views of FIGS. 1 and 2 for convenience of description, but are actually transparent or monochromatic. If the adhesive layers 5 and 5A are formed continuously or in a solid line around the periphery, the paper 1 is easily damaged when the right paper 3 is peeled off, and depending on the size (width) of the adhesive layers 5 and 5A, curl may also occur. It is easy to occur. The outer surface 2B of the left paper surface 2 is a printing surface such as a destination address 6, and the outer surfaces (front surfaces) of the left paper surface 2 and the right paper surface 3 are transparent inks 8 having high water repellency. Is applied. Then, the paper surface 1 is folded so that the bonding surfaces 2A and 3A are on the inner side, and the paper surface 1 is folded from the center line M so that the bonding surfaces 2A and 3A are in contact with each other. By bonding, a simple concealed envelope as shown in FIG. 2 is obtained. At this time, in this embodiment, the adhesive layers 5, 5A are formed on both sides of the bonding surfaces 2A, 3A, and the adhesive layers 5, 5A on both bonding surfaces are formed so as not to overlap with each other. The adhesive layers 5 and 5A do not overlap and cause blocking, and are staggered so that air can escape easily. Even if pressure is applied to the sheet of paper 1 sometimes, an escape path for the air from the inner part is secured and the air can be released quickly, so that the adhesive layers 5 and 5A once adhered to each other by the pressure of the air flow do not peel off. It has become. Reference numeral 7 denotes a knob allowance for separating the left paper surface 2 and the right paper surface 3 formed at the corners of the paper surface 1.

In the simple concealment envelope of this embodiment as described above, the heat-sensitive or pressure-sensitive adhesive forming the adhesive layers 5 and 5A has temporary adhesive properties in terms of adhesive strength and release properties. It is preferable to use a natural or synthetic rubber type paste. Here, the temporary adhesive property is a property that exhibits a certain adhesive strength but can be easily peeled off when a peeling force is applied. Specifically, the temporary adhesive property exhibits a predetermined peeling strength in a width and a length as described later. It does. The adhesive layers 5 and 5A are preferably formed to have a width (W) of 2.5 to 3.5 mm and a length (L) of 40 to 80 mm. When the width (W) of the adhesive layers 5 and 5A is less than 2.5 mm, the bonding between the left paper surface 2 and the right paper surface 3 is not sufficient, and it is easy to peel off. 3, the paper surface 1, especially the right-hand paper surface 3, is easily damaged or bent when peeled, and a light feeling of peeling is not obtained. If the length (L) of the adhesive layers 5 and 5A is less than 40 mm, the bonding between the left paper surface 2 and the right paper surface 3 is not sufficient, and it is easy to peel off. The paper surface 1, especially the right-hand paper surface 3, is not only easily damaged or bent when peeled off, but also does not provide a light peeling feeling. The distance (D) between the adhesive layers 5 and 5A may be about 8 to 12 mm.

By bonding the left paper surface 2 and the right paper surface 3 with the adhesive layer 5 as described above, the bonding strength (peeling strength) becomes 8 to 22 N / m with a 180 ° peel force, Easy peelability can be exhibited without impairing the bondability between the paper surface 2 and the right paper surface 3. Here, the 180-degree peel force is the 180-degree peel force of the adhesive layers 5 and 5A shown in FIG. 1 at six places when peeled in the lateral direction at a peel speed of 0.3 m / min. Yes, it is sufficient to judge by the average value of ten or more measurement results. This 180 ° peeling force slightly varies depending on the bonding location, length and width, etc., but within the range of 8 to 22 N / m, good bonding properties can be exhibited. The above-mentioned adhesive strength can be adjusted to a desired value by changing the width (W) and length (L) of the adhesive layers 5 and 5A, and the concentration and application amount of the adhesive.

The operation of the above configuration will be described. When opening the simple concealment envelope of the present embodiment, first, as shown in FIG. Then, it is sequentially peeled from the outer adhesive layer in FIG. At this time, the adhesive layers 5 and 5A are provided intermittently, and the adhesive strength of the adhesive layers 1 to 8 is set to 8 to 22 N / m by 180 ° peel force. And the right paper 3 can be easily peeled off, so that the paper 1 is not damaged even though the left paper 2 and the right paper 3 are securely bonded. Subsequently, when the right side paper 3 is completely peeled off from the left side paper 2, the concealment information 6 printed on the left side paper 2 and the right side paper 3 can be visually recognized. Since the adhesive layers 5 and 5A are intermittently formed only on the peripheral portion of the right paper surface 3, the left paper surface 2 and the right paper surface 3 do not curl. It is suitable for direct machine processing as paper.

As described in detail above, the simple concealment envelope, which is the concealed information holding body of the present embodiment, corresponds to claim 1, and a pair of releasable stickers is attached to the paper 1 where the left paper 2 and the right paper 3 are continuous. By providing the bonding surfaces 2A and 3A, forming the adhesive layer 5 on at least one of the bonding surfaces 3A, holding the concealment information 4 on the bonding surfaces 2A and 3A, and bonding them together, the concealment information 4 is always concealed. When the bonding surfaces 2A and 3A are peeled off, the information becomes visible. Since the adhesive layer 5 is provided intermittently on the periphery of the bonding surface 3A, the adhesive layer 5 Since the adhesive layer 5 is not formed on the entire surface of the bonding surface 3A, the adhesive layer 5 does not cause curl on the paper surface 1. Further, when the right paper surface 3 is peeled off at the bonding surface 3A, the paper surface 1 is firmly attached to the paper surface 1. Damage It is not going to be. In addition, since no adhesive is applied to the center of the bonding surface 3A, it is possible to use a pen or the like as a description field.

In addition, according to claim 2, since natural or synthetic rubber having temporary adhesive properties is used as the adhesive, the bonding surfaces 2A, 3A are bonded with an appropriate bonding strength. Is possible.

According to the third aspect, since the adhesive layer is provided intermittently with a width of 2.5 to 3.5 mm and a length of 40 to 80 mm, the bonding surface 2A Even if the 3A is firmly adhered, the paper 1 is not damaged and is easily peeled off, so that the paper 1 is not curled.

The adhesive layers 5 and 5A are formed on both surfaces of the bonding surfaces 2A and 3A, and the adhesive layers 5 and 5A on both the bonding surfaces do not overlap each other. The adhesive layers 5 and 5A are not overlapped with each other to cause blocking, because they are formed on the peripheral portion asymmetrically in the vertical direction and are staggered so that air can easily escape. , 5A are staggered, so that an escape path for air from the inner part is secured during bonding, so that the adhesive layers 5, 5A bonded to each other are not separated by the pressure of the air flow. .

Further, according to claim 5, since the adhesive strength of each of the adhesive layers 5 and 5A is 8 to 22 N / m at a peeling force of 180 °, the paper surface 1, especially the right side The paper surface 3 is not damaged and is easily peeled off, and the paper surface 1 is not curled.

As described above, the concealed information possessor of the present invention has been described with reference to the accompanying drawings. However, the present invention is not limited to the above embodiment, and various modifications may be made within the spirit of the present invention. Is possible. For example, in the above-described embodiment, the case has been described in which the envelope 1 is arranged horizontally in the horizontal direction as the paper surface 1 and the continuous left and right paper surfaces 2 and 3 are used. The left side paper surface 2 and the right side paper surface 3 that are arranged side by side may be used, and the continuation direction of the paper surface 1 is not particularly limited. In addition, the size of the paper 1 may be various sizes such as a postcard size made by a government, and it is needless to say that the concealed information holding body is not limited to envelopes but can be widely applied to other information transmitting bodies. . Further, in the above-described embodiment, the configuration is such that the sheet is folded in two and bonded, but the sheet may be folded in three. Furthermore, a function as a concealed information holder is provided, for example, by forming a resin coating layer for improving the releasability on the bonding surface 2A of the left side paper surface 2 in correspondence with the adhesive layers 5 and 5A.
