Abstract

This invention relates to a post card including a post card base sheet and a bonded material which is bonded to at least part of the post card base sheet. The bonded material includes a sheet base material having a shielding property, a first heat-bondable resin layer formed on one of the main planes of the sheet base material and having low bonding power and a second heat-bondable resin layer formed at part of the surface of the first heat-bondable resin layer and having high bonding power, and is bonded to the surface of the post card base sheet by the first and second heat-bondable resin layers. The first heat-bondable resin layer is weakly bonded to the post card base sheet and the second heat-bondable resin layer, strongly. Accordingly, the sheet substrate will not by any chance peel off from the post card base sheet due to the force acting on the portion where the second heat-bondable resin layer is formed. When the sheet base material or the like is cut and peeled at the portion where the second heat-bondable resin layer is not formed, the first heat-bondable resin layer is peeled off from the post card base sheet along with the sheet base material in the case of a post card including the sheet base material having the shielding property and on the other hand, the shielding layer and the first heat-bondable resin layer are peeled off from the post card base sheet along with the sheet base material in the case of a post card including the shielding layer having the shielding property. Accordingly, the surface of the base sheet of the post card becomes visible. Thus the present invention provides a post card capable of shielding suitably and temporarily the indicated items on the surface of the post card base sheet without applying any machining or treatment to the surface of the post card base sheet, and a method of its production.

The covering material 14 covers a base material 18 of the sheet, and the base material 18 is made of a relatively flexible material that can be cut with scissors, such as paper or a synthetic resin film. The substrate 18 is engraved, and a cover layer 20 is formed on one main surface of the substrate 18.

The concealed layer 20 is printed with a solid silver print using silver ink, for example. It is formed by laminating a film material having a hiding power such as aluminum foil with an adhesive or the like.

On the surface of the hidden layer 20, for example, a gravure or silk screen is coated by extruding a heat-adhesive resin having a weak adhesive force while heating, or dissolving in a solvent or dispersing in water. By printing a screen or the like, the first heat-adhesive resin layer 22 having a weak adhesive strength is formed.

On the other hand, the recirculated material transfer device 1 20 transfers the coating material remuneration 14 a from the reel i 22, and the coating material detection device i 24 accordingly causes the coating material connecting member i 4 a In this embodiment, the detection mark formed on the surface of the member, by detecting the arrow, also temporarily stops the transfer of the coating material 14a, At this time, the coating material cutting device 丄 26 is activated, and the cutters i 30 a and i 30 b are coated by the force groove of the disk 142. Cut the continuous member of material 丄 4 a into appropriate size, that is, one piece of covering material 被覆 4. The tip of the coating material 14 cut into an appropriate size by the coating material cutting device 12 26 is located at an optimal position on the surface of the continuous postcard 10a. In the width direction of the continuous postcard continuous paper i0a, the leading end is pressurized and heated in a straight line において in the width direction of the continuous postcard continuous paper i0a, and the surface of the continuous postcard continuous raw paper 10a is initially formed. The tip of the covering material is adhered to this.

At that time, at the same time as the pressurizing and heating, the continuous postcard 10a is moved a certain distance by the operation of the continuous paper transporting device 102, and in this embodiment, is downstream by a length corresponding to approximately one length of the covering material 14 in this embodiment. Is transferred to That is, in the previous cycle, the coating material 1 and the postcard mount i2 located at the lower part of the planar pressurizing and heating device i54 are pressurized and heated, and at the same time, the downstream of the postcard continuous base paper 10a. With the movement, the coating material 14 is transferred by a predetermined distance.

Then, after the bonding part transfer table i i 8 has moved a predetermined amount on the rail body 1 74, the linear press ripening device is again operated by the action of the cam groove of the disk i Ί 2.

15 2 and the planar pressure heating device 15 4 are separated from the bonding portion transfer table 1 18 and are located above. At the same time, the linear pressurizing and heating device 15 2 and the surface pressurizing and heating device 15 4 together with the bonding portion transfer table ii 8 are moved in the opposite direction to the flow of the postcard connecting element 10 a, That is, it moves to the original predetermined position on the upstream side. At this time, the pressing roller 1 6 2

The surface of 4 will be pressed while rolling HI.

Then, at the tip position of the coating material 14 that was sent later in the next cycle through the process of cutting the coating material continuum 14a again, the bonding part transfer table 118 was pressed. The wire forming the heating device ί 50 祆 the pressure ripening device i 52 and the planar pressure heating device ί 54 are joined. At this time i 9

The coating material 14 sent in the previous cycle is located at the lower part of the planar pressure heating device 15. Then, the continuous base paper 10a, to which the leading end of the covering material 14 of the next cycle is adhered, is transported by a certain distance by the operation of the continuous paper transport device 102, and is first transferred to the previous cycle. The coating material 14 that has been sent before is pressed and heated by the planar pressure heating device 15 54.

In other words, when the covering material 14 having the tip bonded thereto is located at the lower part of the planar pressurizing and heating device i54 (the initial upstream tilt position), the surface pressurizing and heating device i54 Is pressed against the surface of the bonded part transfer base i 18 by the action of the cam groove formed in the disk i Ί 2, and pressurizes and heats the coating material i 4.

The transfer distance of the postcard continuous base paper i 0 a is also regulated by the pulse generated by the encoder formed in the continuous paper transfer unit 102, and the coating material is covered by the central processing unit i 76. It is configured to control the transfer of the transfer device 120, the coating material cutting device i 26, and the pressure heating device i 50. However, the postcard continuous base paper 10a is formed so as not to move backwards, and the linear pressure heating device 15 2 and the sheet pressure heating device of the adhesive transfer table ii 8 and the pressure heating device i δ 0 It is formed so that it does not run in reverse, corresponding to the reverse of 1 5 4.

As described above, the pressurizing and heating device 150 turns the cycle of the forward, the thought point (downstream side), the reverse, and the thought point (upstream side), and as shown in FIG. A covering material 14 is appropriately bonded to the surface of the postcard platform 12 constituting i 0.

Then, the continuous paper i0 partially covered with the covering material i4 in this way is appropriately folded, and then appropriately cut off, and Will be submitted.

The coating material i4 thus bonded was strongly bonded at the portion where the second heat-adhesive resin layer 24 was formed, and the second heat-adhesive resin layer 24 was not formed. Weakly adhered in parts. Therefore, as shown in FIGS. 12A and 12B, in the portion where the second heat-adhesive resin layer 24 is not formed, the base material 18, the hidden layer 20 and The i-th heat-adhesive resin layer 22 can be cut off from the postcard backing sheet 12 relatively easily. In this case, the base material 18, the hidden layer 20 and the first mature adhesive resin layer 22 can be easily formed even in the spot where the second mature adhesive resin layer 24 is formed in a spot shape. Can be peeled off. Then, you can see the lottery part i 3 a and the secret matter 13 b on the surface of the postcard mount i 2.

In this embodiment, in particular, the base material 18, the cover layer 10, and the upper and lower ends of the first thermo-adhesive resin layer 22, along the edges of the second thermo-adhesive resin layer 24. For example, cuts 26a and 26b formed of perforations are formed. These cuts 26a and 26b are formed by, for example, a cut forming device including a roll with cut teeth, a so-called die roll, or a cut forming device including a die cutter having cut teeth.

Therefore, in this example, as shown in FIGS. I4A and i4B, the base material i 8, the concealed portion was not formed in the portion where the second heat-adhesive resin layer 24 was not formed. The pad layer 20 and the first heat-adhesive resin layer 22 can be cut off at cuts 26a and 26b, and can be relatively easily pulled off from the postcard mount i2. Then, the lottery 1 on the surface of the postcard mount 2 2 i

FIGS. 丄 7A and i7B are examples of the present invention. FIG. 17A is a perspective view thereof, and FIG. 17B is a sectional view thereof.

FIGS. 18A and 18B are views showing a state in which the covering material of the above embodiment is cut and pulled from the postcard base 、, and FIG. 18A is a perspective view thereof. FIG. 8B is a cross-sectional view thereof.

This postcard includes postcard material 2 10, and postcard material 2 i 0 is a government-made postcard-sized postcard mount 2 1 2 and a part of this postcard mount 2 1 2. Includes barrel coating 2i4. The covering material 2 14 extends from one end of the postcard mount 2 12 and is integrally formed, and is folded back and adhered to the postcard mount 2 12.

Also, on the surface of the postcard mount 2 12, for example, a lottery section 2 13 a such as a hit and a miss and a secret matter 2 i 3 b such as a guide for finance and insurance are formed.

The covering material 2 i 4 includes a base material 2 18 integrally formed by extending from one end of a postcard interleaving paper 2 i 2, and the base material 2 2 8 is, for example, paper, a synthetic resin film, or the like. It is formed of a material that is relatively flexible and can be cut with scissors or the like, and an opaque layer 220 is formed on one main surface of the substrate 2 i 8.

On the surface of the concealing layer 220, for example, a heat-adhesive resin having a weak adhesive strength is extruded and coated while heating, or is dissolved in a solvent or dispersed in water to form a gravure or silk screen. By performing the first printing, the i-th heat-adhesive resin layer 222 having a low adhesive strength is formed.

The first heat-adhesive resin layer 222 is melted at a temperature of, for example, 100 ′ c to 200 ° C., and is weakened, for example, to a postcard backing sheet 212 made of paper. It is formed so that it can be bonded with a low adhesive strength.

As an example of the above-mentioned mature adhesive resin having a low adhesive strength, an EVA-based adhesive or the like, which is the same as the embodiment shown in FIG. 1 can be selected.

Further, a second heat-adhesive resin layer 22 having a strong adhesive force is formed on the surface of the first heat-adhesive resin layer 222. In this embodiment, the second heat-adhesive resin layer 224 is formed with a certain width on both sides of the longitudinal direction i of the postcard mount 12, that is, on the upper and lower ends of the covering material 14. Further, the second heat-adhesive resin layer 224 is formed in a spot shape on both sides in the width direction of the postcard backing paper 12, that is, on both right and left ends of the covering material 14. The second heat-adhesive resin layer 222 is formed on the surface of the first heat-adhesive resin layer 222 by, for example, an EVA-based adhesive, a styrene-butadiene-styrene copolymer, or a styrene. It is formed by partially applying a heat-adhesive resin having a strong adhesive force, such as a ren-so-prene-styrene copolymer. In this case, the heat-adhesive resin material with strong adhesive strength contains, for example, a larger amount of tackifier or the release agent than the heat-adhesive resin material with weaker adhesive strength. Or not. Note that the second heat-adhesive resin layer 222 may be formed on the surface of the first heat-adhesive resin layer 222 only at the upper and lower ends or at both left and right ends of the covering material 14.

Next, a method of manufacturing this postcard will be described.

First, a continuous paper for forming a postcard 2I0 is prepared. A postcard interleaving paper 2i2 part and a base material 218 part are continuously formed in the width direction of the continuous part. Therefore, the length of the width 1 of the continuous paper is the total length of the length of the postcard mount 2 12 and the length of the base material 2 18. On the other hand, Oki layer 2 Form a 0.

Then, using an apparatus similar to the apparatus shown in FIG. 3, as shown in FIG. 19, an opaque layer 220 is formed on one main surface of the base material 218 portion, and the first heat adhesive property is obtained. A postcard material 210 on which a covering material 214 formed by sequentially laminating a resin layer 222 and a second heat-adhesive resin layer 222 is produced.

Subsequently, the postcard material 210 is guided to a coating material sticking device which sticks the coating material 214 portion to the postcard mount 211 portion. At this time, in order to cover the confidential matters such as the bank deposit balance formed on a part of the surface of the postcard with this covering material 2 i 4, it is necessary to previously place an appropriate place on the postcard material, for example, in the lower surface column. It is necessary to print appropriate characters in advance. When this covering material 214 is to be adhered to, for example, the lower column of the postcard, the postcard material 210 is sequentially sent in, and as shown in FIG. It is folded back at the boundary between the four portions, and the postcard mount 2 12 and the covering material 2 i 4 are joined. Then, the covering material 214 may be attached to the surface of the postcard backing paper 2i2 while the surface of the postcard material 2i0 is pressed by a pressing roller. Then, the postcard 210 is pressed to an appropriate size, and the postcard of the present invention is formed.

The coating material 214 bonded in this manner is strongly bonded at the portion where the second thermo-adhesive resin layer 224 is formed, and the second thermo-adhesive resin layer 224 is formed. Therefore, as shown in FIG. 18A and FIG. 8B, in the portion where the second mature adhesive resin layer 224 is not formed, the base material is hardly adhered. The 28, the concealing layer 220, and the ith heat-adhesive resin layer 222 can be cut off from the postcard mount ί2-2 relatively easily. This place In this case, even when the second heat-adhesive resin layer 224 is formed in a spot shape, the base layer 218, the hidden layer 220 and the i-th heat-adhesive resin layer 222 Can be easily removed. Then, it is possible to see the lottery 2 13 a and the secret 2 i 3 b on the surface of the postcard mount 2 12. FIGS. 21A and 21B show other embodiments of the present invention, respectively. FIG. 21A is a perspective view thereof, and FIG. 2iB is a sectional view thereof. In this embodiment, in particular, the second heat-adhesive resin layer 222 is formed on the upper and lower ends of the base material 218, the hidden layer 220 and the i-th heat-adhesive resin layer 222. For example, cuts 2 26 a and 2 26 b made of perforations are formed along 緣.

Therefore, in this embodiment, as shown in FIG. 22, in the portion where the second mature adhesive resin layer 224 is not formed, the base material 2 i 8, the concealment layer 220 and the second The first heat-adhesive resin layer 2 2 2 can be cut off at cuts 2 2 6 a and 2 2 6 b, and can be relatively easily pulled off from the postcard mount 2 i 2. Then, the user can see the lottery 2 i 3 a and the secret matter 2 ί 3 b on the surface of the postcard mount 2 12.

^ In each of the embodiments described above, the center part of the upper and lower ί of the coating material i 4 is configured to be peelable, but for example, the second heat-adhesive ¾i resin layer 24 is coated with the coating material 14. It is formed in the peripheral portion, and cuts are made in the base material i S, the hidden layer 20 and the second heat-adhesive resin layer 22 along the second heat-adhesive resin layer 2. It may be formed so that the central part of the covering material i 4 can be peeled off from the postcard mount 12 by being formed.

Further, in each of the embodiments described above, the lottery portion 13a is formed on the surface of the postcard mount i2, but the lottery portion i3a is hidden when the cover layer 20 is provided. The surface of the backing layer 20 and the surface of the postcard mount 1 2 It may be formed on the shifted surface, and when it does not have the hidden layer 20, it may be formed on any one of the main surface of the base material i 8 and the surface of the postcard mount 12.

Further, in each of the embodiments described above, the cut may be formed around the periphery of the base material on the surface. By forming the cuts in this way, only the central portion of the covering material can be peeled off. In this case, as shown in FIG. 23, one cut 3 2 4 is formed so that a part of the adjacent cut 3 2 overlaps when viewed in the direction in which the covering material 3 12 is peeled off. If it is composed of the part 3 2 4 a and the arc-shaped cut part 3 2 4 b, the center part of the covering material 3 12 can be easily peeled off. In order to easily peel off the central part of the adhesive in this way, for example, as shown in FIG. The linear cuts 424 may be formed diagonally around the base material 4i4 so that the adjacent cuts 424 overlap.

In the postcards shown in Figs. 23 and 24, when the covering material is pulled in the direction indicated by the arrow, the covering material between adjacent cuts is drawn as indicated by the dashed line arrow in the figure. The film is torn, and the covering material in the notch is pulled off.

In the embodiment shown in FIG. 1 in which the cover is folded, the covering material is attached to a part of the postcard mount, but as shown in FIG. 23 and FIG. It may be formed in the same size as that described above, and it may be attached to the entire surface of the postcard mount.

While this invention has been described and illustrated in detail, it is clear that it is used for purposes of illustration and example only and should not be construed as limiting, the spirit and scope of the invention being set forth in the appended claims. Done It is limited only by the language of a word. Industrial applicability

The ith thermal adhesive resin layer is weakly adhered to the postcard board, and the second mature adhesive resin layer is strongly adhered to the postcard board.
