Description

  TECHNICAL FIELD The present invention relates to a seal with a mount in which a seal substrate in which a plurality of regions are partitioned is pasted to release paper with an adhesive and a method for producing the same, and in particular, a mount using a thermosetting adhesive as the adhesive. The present invention relates to a sticker seal and a manufacturing method thereof.

  Generally, a sticker attached to an article or the like is supplied in a form in which an adhesive is applied to one surface of a sealing base material such as paper and the adhesive is releasably attached to a release paper that becomes a mount. When being attached to an article or the like, the sealing substrate is peeled off from the release paper and attached to the article or the like with an adhesive.

  10A and 10B are diagrams showing a configuration example of a conventional sticker with a mount, in which FIG. 10A is a view seen from the surface, and FIG. 10B is a cross-sectional view taken along line A-A ′ shown in FIG.

  In this configuration example, as shown in FIG. 10, the adhesive 220 is applied to one surface of the seal substrate 210, and the seal substrate 210 is detachably attached to the release paper 230 serving as a mount by the adhesive 220. Configured. In addition, the seal substrate 210 is formed with slits 213, and the seal portions 211 a and 211 b and the cut portions 212 are partitioned by the slit 213. Further, the adhesive 220 is also broken in the region where the slit 213 is formed.

  The seal with the mount configured as described above is configured such that the seal portions 211a and 211b can be selectively separated from the cut portion 212 by the slit 213, and the adhesive 220 is formed in the region where the slit 213 is formed. Since the seal portions 211a and 211b are peeled off from the release paper 230, the seal portions 211a and 211b are separated from the excision portion 212 through the slit 213 together with the adhesive 220 applied to the back surface thereof. Then, it is affixed on articles | goods etc. by the adhesive 220 of the back surface of the seal | sticker parts 211a and 211b, respectively.

As described above, a seal with a mount in which a plurality of seal portions are partitioned is conventionally used (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-156043

  As described above, a plurality of areas such as the seal part and the cut part are configured to be selectively detachable by the slit, and in the seal with the mount in which the adhesive in the area in which the slit is formed is broken, the seal Although the adhesive has been ruptured in order to separate the part and the excised part from the other area together with the adhesive, it has been broken, for example, when the state of being sandwiched from the front and back continues for a long time or due to changes in the adhesive over time, etc. There is a possibility that the adhesive will stick again and the adhesive will not be separated cleanly when the seal part or the cut part is separated from other areas.

  FIG. 11 is a view showing a state where the sticker with mount shown in FIG. 10 is sandwiched from the front and back.

  As shown in FIG. 11, in the state where the sticker with the mount shown in FIG. 10 is sandwiched from the front and back, the adhesive 220 acts to extend in the lateral direction, whereby the broken portions of the adhesive 220 are separated from each other. Are brought into contact with each other and pressed against each other. If this state continues for a long time, the broken portions will be pasted again. In particular, in the case of using a pressure-sensitive adhesive having a strong cohesive force so as to be easily peeled off from an article after being affixed to the article or the like, such a phenomenon is likely to occur when the broken parts come into contact with each other.

  The present invention has been made in view of the problems of the conventional techniques as described above, and is divided into a plurality of regions, together with the thermosetting adhesive applied to the regions. In the case of a sticker with a backing that is selectively peeled off from the release paper, even when the state of being sandwiched from the front and back continues for a long time, etc. It is an object of the present invention to provide a seal with a mount and a method for manufacturing the same, which can cleanly separate the applied adhesive from the adhesive in other regions.

In order to achieve the above object, the present invention provides:
A seal substrate in which a plurality of regions are partitioned is pasted to a release paper with a thermosetting adhesive, and the seal substrate is selectively peeled from the release paper for each of the plurality of regions. A sticker with a mount,
In the pressure-sensitive adhesive, at least a part in the thickness direction of a portion that divides the plurality of regions is broken by heat.

  In the present invention configured as described above, the surface of the broken part of the adhesive is cured by the heat at the time of breaking even if the broken parts of the pressure sensitive adhesive are brought into contact with each other. In addition, since the adhesiveness is weakened, it becomes difficult for the broken portions to stick again. This makes it possible to cleanly separate the pressure-sensitive adhesive from the pressure-sensitive adhesives in other regions when selectively separating the sectioned area from the release paper.

In addition, the manufacturing method of the seal with the mount,
A step of applying the pressure-sensitive adhesive with the release paper attached to one surface of the sealing substrate;
By irradiating laser light from the sealing base material side, the sealing base material is cut and partitioned into the plurality of regions, and at least one portion of the pressure-sensitive adhesive in the thickness direction is partitioned. Breaking the part.

  As described above, in the present invention, in the seal with a mount, which is partitioned into a plurality of regions, and the plurality of regions are selectively peeled off from the release paper together with the thermosetting adhesive applied to the regions. Since at least a part in the thickness direction of the portion that divides the plurality of regions of the curable adhesive is broken by heat, it is applied to the region when the region formed with the separation is selectively peeled from the release paper. The adhesive can be cleanly separated from the adhesive in other areas.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
1A and 1B are diagrams showing a first embodiment of a sticker with a mount according to the present invention. FIG. 1A is a view seen from the surface, and FIG. 1B is a cross-sectional view taken along line AA ′ shown in FIG. is there.

  In this embodiment, as shown in FIG. 1, a release paper 30 formed by applying a silicone-based adhesive 20 on one surface of a seal substrate 10 is detachably attached as a mount of the seal substrate 10. Has been. In addition, a slit 13 is formed in the seal base material 10, and the seal portions 11 a and 11 b and the cut portions 12 that form a plurality of regions are defined by the slit 13. Further, in the region where the slit 13 is formed, the adhesive 20 is also broken, so that the slit 13 penetrates from the seal substrate 10 to the adhesive 20. In addition, a cured portion 21 formed by curing the pressure-sensitive adhesive 20 is formed on the surface of the broken portion of the pressure-sensitive adhesive 20 when the sealing base material 10 and the pressure-sensitive adhesive 20 are broken by heat.

  Below, the manufacturing method of the sticker with a mount configured as described above will be described.

  FIG. 2 is a view for explaining a method of manufacturing the sticker with mount shown in FIG.

  First, a release paper 30 formed by applying a silicone-based pressure-sensitive adhesive 20 is attached to the back surface of a sealing substrate 10 such as paper (FIG. 2A). As a result, the adhesive having the release paper 30 attached thereto is applied to one surface of the seal substrate 10. As the silicone-based pressure-sensitive adhesive 20, it is conceivable to use a silicone-based substrate-less double-sided tape. For example, the silicone-based pressure-sensitive adhesive 20 contains silicone rubber or silicone resin containing organopolysiloxane as a main component, and a crosslinking agent is added thereto. It may be formed by adding and curing. In addition, the release paper 30 may be configured, for example, by using paper or a film as a base material and applying a fluorine-based release agent such as silicone fluoride on one surface thereof.

Next, a laser beam 41 composed of a CO ₂ laser is irradiated from the laser light source 40 to the region where the slit 13 of the seal substrate 10 is formed (FIG. 2B). At this time, the laser light source 40 is adjusted so that the power and focal length of the laser light 41 are such that the slit 13 penetrates from the sealing substrate 10 to the adhesive 20 by the laser light 41. However, the release paper 30 is preferably not cut by the laser light 41.

  By irradiating the laser beam 41 from the laser light source 40 to the area where the slit 13 of the sealing base material 10 is formed, the slit 13 is formed in the sealing base material 10 and the area where the slit 13 is formed is adhered. The agent 20 is broken. At this time, since the pressure-sensitive adhesive 20 is a thermosetting silicone-based pressure-sensitive adhesive 20, the pressure-sensitive adhesive 20 is cured by the heat of the laser beam 41 on the surface of the pressure-sensitive adhesive 20 that is broken by the laser beam 41. Thus, the cured portion 21 is formed (FIG. 2C).

  Below, an effect | action of the seal | sticker with a mount manufactured as mentioned above is demonstrated.

  FIG. 3 is a diagram showing a state where the mount sticker shown in FIG. 1 is sandwiched from the front and back.

  As shown in FIG. 3, in the state where the sticker with the mount shown in FIG. 1 is sandwiched from the front and back, the adhesive 20 acts so as to extend in the lateral direction, whereby the broken portions of the adhesive 20 are separated from each other. Come into contact and press each other. However, since the hardened portion 21 cured by heat at the time of breakage is formed on the surface of the broken portion of the adhesive 20, the adhesiveness of the portion is weakened, and the broken portions are separated from each other. It is difficult to stick again. Moreover, since the wrinkles of the sealing base material 10 cut by the laser beam 41 are attached to the surface of the broken part of the adhesive 20, the broken parts of the adhesive 20 are more difficult to stick to each other. Yes.

  Below, the usage method of the sticker with a mount mentioned above is demonstrated.

  4 and 5 are diagrams for explaining how to use the sticker with the mount shown in FIG.

  For example, when the seal portions 11a and 11b are selectively peeled from the cut portion 12 and used, as shown in FIG. 4, when the seal portions 11a and 11b are peeled from the release paper 30, the region where the slit 13 is formed. In FIG. 2, since the adhesive 20 is also broken, only the areas of the adhesive 20 applied to the back surfaces of the seal portions 11a and 11b are peeled off from the release paper 30, respectively. At this time, the broken portion of the pressure-sensitive adhesive 20 has the hardened portion 21 formed as described above and is difficult to stick to each other, so that the portion is also cleanly separated from the pressure-sensitive adhesive in other regions. Become. Thereafter, the seal portions 11a and 11b peeled from the release paper 30 are attached to the article or the like by the adhesive 30 on the back surface.

  Further, when the seal with the mount is supplied in a state where only the seal portions 11a and 11b of the seal base material are detachably attached to the release paper 30, as shown in FIG. Since the adhesive 20 is also broken in the area where the slit 13 is formed, only the area applied to the back surface of the cut portion 12 is peeled off from the release paper 30. become. At this time, the broken portion of the pressure-sensitive adhesive 20 has the hardened portion 21 formed as described above and is difficult to stick to each other, so that the portion is also cleanly separated from the pressure-sensitive adhesive in other regions. Become. Thereafter, the seal with the mount is supplied in a state where only the seal portions 11 a and 11 b of the seal base material are detachably attached to the release paper 30.

(Second Embodiment)
6A and 6B are diagrams showing a second embodiment of the sticker with mount according to the present invention, wherein FIG. 6A is a view seen from the surface, and FIG. 6B is a cross-sectional view taken along line AA ′ shown in FIG. is there.

  In this embodiment, as shown in FIG. 6, a release paper 130 formed by applying a silicone-based adhesive 120 is attached to one surface of a seal base 110 so as to be peelable as a mount of the seal base 110. Has been. In addition, a slit 113 is formed in the seal substrate 110, and seal portions 111 a to 111 f serving as a plurality of regions are defined by the slit 113. Further, in the region where the slit 113 is formed, a part of the adhesive 120 in the thickness direction is broken, and the adhesive 120 is cut to a predetermined depth from the seal base 110 side. It has become. Further, a cured portion 121 formed by curing the adhesive 120 is formed on the surface of the fractured portion of the adhesive 120 when the seal substrate 110 and the adhesive 120 are fractured by heat.

  Below, the manufacturing method of the sticker with a mount configured as described above will be described.

  FIG. 7 is a view for explaining a method of manufacturing the sticker with mount shown in FIG.

  First, a release paper 130 to which a silicone-based adhesive 120 is applied is attached to the back surface of a sealing substrate 110 such as paper (FIG. 7A). As a result, the adhesive having the release paper 130 attached thereto is applied to one surface of the seal substrate 110.

Next, a laser beam 141 composed of a CO ₂ laser is irradiated from the laser light source 140 to a region where the slit 113 of the seal substrate 110 is formed (FIG. 7B). At this time, the power and focal length of the laser beam 141 are such that the seal substrate 110 in the region where the slit 113 is formed by the laser beam 141 is cut and a part of the adhesive 120 in the thickness direction of the region is cut. The laser light source 140 is adjusted so as to be broken.

  By irradiating the laser beam 141 from the laser light source 140 to the area where the slit 113 of the sealing base 110 is formed, the slit 113 is formed in the sealing base 110 and the adhesive of the area where the slit 113 is formed. Part of the agent 120 in the thickness direction is broken. At this time, since the adhesive 120 is a thermosetting silicone-based adhesive 120, the adhesive 120 is cured by the heat of the laser light 141 on the surface of the adhesive 120 that is broken by the laser light 141. Thus, the cured part 121 is formed (FIG. 7C). Here, the thickness at which the adhesive 120 is broken by the laser beam 141 is preferably such that the cured portion 121 formed on the broken surface reaches the release paper 130, but may be arbitrary. This eliminates the need to finely adjust the power and focal length of the laser beam 141.

  Below, an effect | action of the seal | sticker with a mount manufactured as mentioned above is demonstrated.

  FIG. 8 is a view showing a state where the sticker with mount shown in FIG. 6 is sandwiched from the front and back.

  As shown in FIG. 8, in the state where the seal with the mount shown in FIG. 6 is sandwiched from the front and back, the adhesive 120 acts so as to extend in the lateral direction, so that the broken portions of the adhesive 120 are separated from each other. Come into contact and press each other. However, since the hardened portion 121 cured by heat at the time of breaking is formed on the surface of the broken portion of the adhesive 120, the adhesiveness of the portion is weakened, and the broken portions are pasted again. It is hard to wear. Moreover, since the wrinkles of the sealing base material 110 cut by the laser beam 141 are attached to the surface of the broken portion of the adhesive 120, the broken portions of the adhesive 120 become more difficult to stick. Yes.

  Below, the usage method of the sticker with a mount mentioned above is demonstrated.

  FIG. 9 is a view for explaining a method of using the sticker with mount shown in FIG.

  When the seal portions 111a to 111f of the stickers with mount shown in FIG. 6 are selectively peeled and used, as shown in FIG. 9, when the seal portions 111a to 111f are peeled from the release paper 130, a slit 112 is formed. Since the adhesive 120 is partially broken in the thickness direction in the region thus formed, and further, the cured portion 121 formed on the fractured surface is formed to the extent that the release paper 130 is reached. As for the agent 120, only the areas applied to the back surfaces of the seal portions 111a to 111f are peeled off from the release paper 130, respectively. At this time, the broken portion of the adhesive 120 has the hardened portion 121 formed as described above and is difficult to stick to each other, so that the portion is also cleanly separated from the adhesive in other regions. Become. Thereafter, the seal portions 111a to 111b peeled from the release paper 130 are attached to the article or the like by the adhesive 130 on the back surface.

  It is also conceivable that the above-described two embodiments are combined. That is, as shown in FIG. 1, the thickness of the adhesive 20 in the region where the slit 13 is formed in the seal with a mount in which the seal portions 11 a and 11 b and the cut portion 12 are defined by the slit 13 on the seal base material 10. The slit 113 is formed in the seal with a mount in which the seal portion 111a to 111f is partitioned by the slit 113 on the seal base 110 as shown in FIG. It is also conceivable that the adhesive 120 in the formed region is broken.

  In the two embodiments described above, the sealing base materials 10 and 110 and the pressure-sensitive adhesives 20 and 120 are broken by the laser beams 41 and 141, but the heat is high enough to cure the pressure-sensitive adhesives 20 and 120. What is necessary is just to fracture | rupture the sealing base materials 10 and 110 and the adhesives 20 and 120 by a cutting means.

  Further, in the two embodiments described above, the silicone-based pressure-sensitive adhesive has been described as an example of the pressure-sensitive adhesive 20, 120 applied to the seal base material 10, 110, but the present invention is not limited thereto, Various thermosetting pressure-sensitive adhesives that cure when heated by laser light or the like can be used.
