図２と図３に示すように、一方の粘着剤層３３に離型紙４０が被着された両面粘着テープ本体３１は、台紙３５から剥離されて粘着剤層３４を露出した状態で、成形品本体２１の裏面２３の凸角縁２６で離型紙４０側を凸として折り曲げられると共に、他方の粘着剤層３４で成形品本体２１の裏面２３の第１及び第２貼着面２４、２５に連続して貼着される。
成形品本体２１の裏面２３の第１及び第２貼着面２４、２５の間の凸角縁２６に沿って折り曲げられた離型紙４０の曲げ部分には、凸角縁２６に沿って部分的に切断された分離部４２が予め形成されている。
離型紙４０の分離部４２は、この離型紙４０を超えて両面粘着テープ本体３１の基材３２に及んで形成されることが望ましく、さらに、両面粘着テープ本体３１を超えて台紙３５まで及んで形成されることがより一層望ましい。
また、離型紙４０の分離部４２は、凸角縁２６に対応する部分に沿い、所定の間隔を保って連続した線状に複数個形成され、複数個の分離部４２間には離型紙４０が連続する連結部４３が形成されている。
また、分離部４２の長さは、連結部４３の長さよりも長く形成されることが望ましい。 As shown in FIGS. 2 and 3, the double-sided pressure-sensitive adhesive tape main body 31 having the release paper 40 attached to one pressure-sensitive adhesive layer 33 is peeled off from the mount 35 and the pressure-sensitive adhesive layer 34 is exposed, and the molded product The convex edge 26 of the back surface 23 of the main body 21 is bent so that the release paper 40 side is convex, and the other adhesive layer 34 is continuous with the first and second sticking surfaces 24 and 25 of the back surface 23 of the molded product main body 21. And pasted.
The bent portion of the release paper 40 that is bent along the convex edge 26 between the first and second attachment surfaces 24, 25 of the back surface 23 of the molded article body 21 is partially along the convex edge 26. The separation part 42 cut into two is formed in advance.
The separation portion 42 of the release paper 40 is preferably formed so as to extend beyond the release paper 40 and to the base material 32 of the double-sided pressure-sensitive adhesive tape main body 31, and further to the mount 35 beyond the double-sided pressure-sensitive adhesive tape main body 31. It is even more desirable that it be formed.
In addition, a plurality of separation portions 42 of the release paper 40 are formed in a continuous line at a predetermined interval along a portion corresponding to the convex corner edge 26, and the release paper 40 is interposed between the plurality of separation portions 42. A connecting portion 43 is formed.
In addition, it is desirable that the length of the separation portion 42 is longer than the length of the connection portion 43.

図４と図５に示すように、離型紙４０の外形縁近傍の表面には、両面粘着テープ本体３１に対する離型紙４０の粘着力よりも大きい粘着力を有する粘着剤層５１を一側面の一部に設けた帯状のタブテープ５０がその粘着剤層５１で貼着されており、タブテープ５０に外力を加えて離型紙４０を剥離可能としている。
また、タブテープ５０の粘着剤層５１の一部が離型紙４０の外形縁を超えて延び、この超えて延びた部分の粘着剤層５１の部分が両面粘着テープ本体３１の外形縁近くに位置する成形品本体２１の一部（外周突縁２７）に貼着している。 As shown in FIGS. 4 and 5, an adhesive layer 51 having an adhesive force larger than the adhesive force of the release paper 40 with respect to the double-sided adhesive tape body 31 is provided on one surface of the side surface near the outer edge of the release paper 40. A strip-shaped tab tape 50 provided in the section is stuck with the adhesive layer 51, and an external force is applied to the tab tape 50 so that the release paper 40 can be peeled off.
Further, a part of the pressure-sensitive adhesive layer 51 of the tab tape 50 extends beyond the outer edge of the release paper 40, and the part of the pressure-sensitive adhesive layer 51 that extends beyond this is positioned near the outer edge of the double-sided pressure-sensitive adhesive tape main body 31. It is affixed to a part (outer peripheral protrusion 27) of the molded product main body 21.

上述したように構成されるこの実施例１において、成形品本体２１の裏面２３に両面粘着テープ本体３１を貼着して成形品２０を構成する場合、予め、台紙３５から両面粘着テープ３０の主体部をなす両面粘着テープ本体３１が剥離される。
次に、成形品本体２１の裏面２３の凸角縁２６で離型紙４０側を凸として折り曲げられると共に、離型紙４０が被着されていない側（台紙３５が剥離された側）の粘着剤層３４で成形品本体２１の裏面２３の第１及び第２貼着面２４、２５に連続して両面粘着テープ本体３１が貼着されることによって成形品２０が構成される。
離型紙４０には、凸角縁２６に沿って部分的に切断された分離部４２が予め形成されるため、離型紙４０は、その分離部４２において、成形品本体２１の凸角縁２６に沿って凸となるように円滑に曲げられる。このため、離型紙４０の分離部４２で、折り曲げ方向に引張応力が残存するのを防止することができる。これにより、離型紙４０の復元力を減少させ、両面粘着テープ本体３１の粘着剤層３３から離型紙４０が部分的に剥がれて浮き上がることを防止することができる。
この結果、離型紙４０が不測に剥がれず、両面粘着テープ本体３１の粘着剤層３３に塵や埃等が付着する不具合を解消することができ、被取付体１０に対し成形品２０を貼着不良なく良好に貼着して固定することができる。 In the first embodiment configured as described above, when the molded product 20 is configured by adhering the double-sided adhesive tape main body 31 to the back surface 23 of the molded product main body 21, the main body of the double-sided adhesive tape 30 is previously formed from the mount 35. The double-sided pressure-sensitive adhesive tape main body 31 forming the part is peeled off.
Next, an adhesive layer on the side where the release paper 40 is not attached (the side on which the mount 35 is peeled) is bent with the convex edge 26 of the back surface 23 of the molded product body 21 being convex. In 34, the double-sided pressure-sensitive adhesive tape body 31 is stuck continuously to the first and second sticking surfaces 24, 25 on the back surface 23 of the molded article body 21, whereby the molded article 20 is configured.
Since the release paper 40 is previously formed with a separation portion 42 that is partially cut along the convex corner edge 26, the release paper 40 is formed on the convex corner edge 26 of the molded product body 21 at the separation portion 42. It is bent smoothly so that it becomes convex along. For this reason, it is possible to prevent the tensile stress from remaining in the folding direction at the separation portion 42 of the release paper 40. Thereby, the restoring force of the release paper 40 can be reduced, and the release paper 40 can be prevented from partially peeling off from the pressure-sensitive adhesive layer 33 of the double-sided pressure-sensitive adhesive tape main body 31 and rising.
As a result, the release paper 40 is not unexpectedly peeled off, and it is possible to eliminate the problem of dust or dirt adhering to the adhesive layer 33 of the double-sided adhesive tape main body 31, and the molded product 20 is adhered to the mounted body 10. Can be stuck and fixed well without defects.

また、離型紙４０の分離部４２がこの離型紙４０を超えて両面粘着テープ本体３１の基材３２に及んで形成される場合には、成形品本体２１の凸角縁２６に沿って離型紙４０及び両面粘着テープ本体３１を曲げやすくすることができる。
さらに、離型紙４０の分離部４２が両面粘着テープ本体３１を超えて台紙３５まで及んで形成される場合には、成形品本体２１の凸角縁２６に沿って離型紙４０及び両面粘着テープ本体３１をより一層曲げやすくすることができる。 Further, when the separation part 42 of the release paper 40 extends beyond the release paper 40 and extends to the base material 32 of the double-sided pressure-sensitive adhesive tape main body 31, the release paper is formed along the convex corner edge 26 of the molded product main body 21. 40 and the double-sided pressure-sensitive adhesive tape main body 31 can be easily bent.
Further, when the separation portion 42 of the release paper 40 is formed to extend beyond the double-sided adhesive tape main body 31 to the mount 35, the release paper 40 and the double-sided adhesive tape main body along the convex edge 26 of the molded product main body 21. 31 can be made even easier to bend.

図７に示すように、離型紙４０の連結部４３の長さよりも長い分離部４２で離型紙４０の折り曲げ方向に引張応力が残存するのをさらに防止することができ、これにより、離型紙４０の復元力を一層減少させることができ、離型紙４０の部分的な剥がれ防止に効果が大きい。
また、図８に示すように、成形品本体２１の裏面２３の外周突縁２７の内周縁２７ａに両面粘着テープ本体３１の外形縁を位置させて両面粘着テープ本体３１を位置ずれすることなく良好に貼着することができる。 As shown in FIG. 7, it is possible to further prevent the tensile stress from remaining in the folding direction of the release paper 40 at the separation portion 42 longer than the length of the connecting portion 43 of the release paper 40. Can be further reduced, and the effect of preventing partial peeling of the release paper 40 is great.
Further, as shown in FIG. 8, the double-sided pressure-sensitive adhesive tape main body 31 is good without being displaced by positioning the outer edge of the double-sided pressure-sensitive adhesive tape body 31 on the inner peripheral edge 27 a of the outer peripheral protruding edge 27 of the back surface 23 of the molded product body 21. Can be attached to.

前記したように構成された成形品２０を被取付体１０の第１及び第２被取付面１２、１３に貼着する場合、先ず、両面粘着テープ本体３１の粘着剤層３３から離型紙４０を剥離した後、図３に示すように、被取付体１０の位置決め孔１５に成形品本体２１の裏面２３の位置決め凸部２８を嵌挿して位置決めする。引き続いて、成形品本体２１及び両面粘着テープ本体３１と共に、粘着剤層３３を被取付体１０の第１及び第２被取付面１２、１３に押圧することによって、被取付体１０の第１及び第２被取付面１２、１３に成形品２０を粘着剤層３３で貼着して固定する。   When sticking the molded article 20 configured as described above to the first and second attached surfaces 12 and 13 of the attached body 10, first, the release paper 40 is removed from the adhesive layer 33 of the double-sided adhesive tape main body 31. After the peeling, as shown in FIG. 3, the positioning convex portion 28 on the back surface 23 of the molded product body 21 is inserted into the positioning hole 15 of the mounted body 10 and positioned. Subsequently, the pressure-sensitive adhesive layer 33 is pressed against the first and second attached surfaces 12 and 13 of the attached body 10 together with the molded product body 21 and the double-sided adhesive tape body 31, thereby The molded product 20 is adhered and fixed to the second attached surfaces 12 and 13 with the adhesive layer 33.

両面粘着テープ本体３１の粘着剤層３３から離型紙４０を剥離する際、離型紙４０の複数個の隣り合う分離部４２間の連結部４３によって離型紙４０が分断されることなく連続しているため、両面粘着テープ本体３１の粘着剤層３３から一度の作業で離型紙４０を容易に剥離することができ、作業性に優れる。
また、この実施例１において、両面粘着テープ本体３１の粘着剤層３３から離型紙４０を剥離する場合には、タブテープ５０を把持した状態で、粘着剤層３３から離型紙４０が剥離する方向へタブテープ５０に外力を加えることによって離型紙４０を容易に手早く剥離することができる（図８参照）。 When the release paper 40 is peeled from the adhesive layer 33 of the double-sided adhesive tape main body 31, the release paper 40 is continuous without being divided by the connecting portions 43 between the plurality of adjacent separation portions 42 of the release paper 40. Therefore, the release paper 40 can be easily peeled from the pressure-sensitive adhesive layer 33 of the double-sided pressure-sensitive adhesive tape body 31 by a single operation, and the workability is excellent.
In Example 1, when the release paper 40 is peeled from the pressure-sensitive adhesive layer 33 of the double-sided pressure-sensitive adhesive tape body 31, the release paper 40 is peeled from the pressure-sensitive adhesive layer 33 while the tab tape 50 is held. By applying an external force to the tab tape 50, the release paper 40 can be easily and quickly peeled off (see FIG. 8).

また、離型紙４０を剥離する前において、タブテープ５０の粘着剤層５１の一部が離型紙４０の外形縁を超えて延びて両面粘着テープ本体３１の外形縁近くの成形品本体２１のの裏面２３、すなわち、外周突縁２７に貼着することによって、離型紙４０の不測の剥がれをより一層良好に防止することができる。また、離型紙４０及び両面粘着テープ本体３１及び台紙３５が同じ外形状で打ち抜かれることによって、両面粘着テープ３０が独立した単品で構成されるため、取り扱いが容易となる。   Before the release paper 40 is peeled off, a part of the adhesive layer 51 of the tab tape 50 extends beyond the outer edge of the release paper 40 and the back surface of the molded product body 21 near the outer edge of the double-sided adhesive tape main body 31. 23, that is, by adhering to the outer peripheral protruding edge 27, it is possible to further prevent unexpected release of the release paper 40. Moreover, since the release paper 40, the double-sided pressure-sensitive adhesive tape main body 31, and the mount 35 are punched out with the same outer shape, the double-sided pressure-sensitive adhesive tape 30 is configured as an independent single item, so that handling becomes easy.

〔実施例３〕
次に、この発明の実施例３を図１１〜図１３にしたがって説明する。
図１１はこの発明の実施例３に係る被取付体に貼着可能な成形品に用いられる両面粘着テープを示す正面図である。図１２は図１１のＸＩＩ−ＸＩＩ線に沿う両面粘着テープの断面図である。図１３は両面粘着テープの離型紙に薄肉状の延伸部が形成される工程を示す説明図である。
図１１と図１２に示すように、この実施例３においては、両面粘着テープ２３０が両面粘着テープ本体３１と、離型紙２４０と、台紙３５とからなり、成形品本体の裏面の凸角縁に沿って折り曲げられる両面粘着テープ本体３１の一方の面の粘着剤層３３に剥離可能に貼着された熱可塑性樹脂シート（例えばポリエチレンシート）よりなる離型紙２４０の所定部分（成形品本体の裏面の凸角縁に対応する部分）に、同離型紙２４０の他の部分と比較して厚さが薄くかつ折り曲げ方向に伸ばされた薄肉状の延伸部２４８が形成されている。 Example 3
Next, a third embodiment of the present invention will be described with reference to FIGS.
FIG. 11: is a front view which shows the double-sided adhesive tape used for the molded article which can be stuck to the to-be-attached body which concerns on Example 3 of this invention. 12 is a cross-sectional view of the double-sided pressure-sensitive adhesive tape taken along line XII-XII in FIG. FIG. 13 is an explanatory view showing a process in which a thin stretched portion is formed on the release paper of the double-sided pressure-sensitive adhesive tape.
As shown in FIGS. 11 and 12, in the third embodiment, the double-sided pressure-sensitive adhesive tape 230 is composed of a double-sided pressure-sensitive adhesive tape body 31, a release paper 240, and a mount 35, and is provided at the convex corner edge on the back surface of the molded product body. A predetermined portion of the release paper 240 made of a thermoplastic resin sheet (for example, a polyethylene sheet) releasably attached to the pressure-sensitive adhesive layer 33 on one side of the double-sided pressure-sensitive adhesive tape body 31 that is bent along (the back surface of the molded product body) In a portion corresponding to the convex corner edge), a thin extending portion 248 having a thickness smaller than that of the other portion of the release paper 240 and extending in the bending direction is formed.

例えば、図１３に示すように、両面粘着テープ２３０の台紙３５を下向きにし、離型紙２４０を上向きにした状態において、加熱された押圧刃６０の線状の刃先６１を離型紙２４０の所定位置に押し当てながら発砲ウレタン等よりなる両面粘着テープ本体３１の基材３２を弾性圧縮させて離型紙２４０の押し当て部分を押し伸ばすことによって薄肉状をなす延伸部２４８が形成される。
この薄肉状の延伸部２４８の肉厚Ｂは、他の部分の肉厚Ａと比較して数分の一程度に薄く形成される。
この実施例３のその他の構成は実施例１と同様にして構成されるため、その説明は省略する。 For example, as shown in FIG. 13, the linear cutting edge 61 of the heated pressing blade 60 is placed at a predetermined position on the release paper 240 in a state where the mount 35 of the double-sided adhesive tape 230 faces downward and the release paper 240 faces upward. A stretched portion 248 having a thin wall shape is formed by elastically compressing the base material 32 of the double-sided adhesive tape main body 31 made of foamed urethane or the like while pressing and stretching the pressed portion of the release paper 240.
The wall thickness B of the thin extending portion 248 is formed to be about a fraction of that of the wall thickness A of other portions.
Since other configurations of the third embodiment are configured in the same manner as the first embodiment, description thereof is omitted.

したがって、この実施例３に係る両面粘着テープ２３０によると、離型紙２４０は、薄肉状をなす延伸部２４８で成形品本体の裏面の凸角縁に沿って凸となるように曲げられている。このため、離型紙２４０の延伸部２４８で、折り曲げ方向に引張応力が残存するのを防止することができる。これにより、離型紙２４０の復元力を減少させ、両面粘着テープ本体３１の粘着剤層３３から離型紙２４０が部分的に剥がれて浮き上がることを防止することができる。   Therefore, according to the double-sided pressure-sensitive adhesive tape 230 according to the third embodiment, the release paper 240 is bent so as to be convex along the convex corner edge on the back surface of the molded product body at the extending portion 248 having a thin shape. For this reason, it is possible to prevent the tensile stress from remaining in the bending direction at the extending portion 248 of the release paper 240. Thereby, the restoring force of the release paper 240 can be reduced, and the release paper 240 can be prevented from partially peeling off from the pressure-sensitive adhesive layer 33 of the double-sided pressure-sensitive adhesive tape body 31 and rising.

なお、この発明は前記実施例１〜３に限定するものではなく、この発明の要旨を逸脱しない範囲内において、種々の形態で実施することもできる。
例えば、実施例１の離型紙４０の分離部４２、又は、実施例３の離型紙２４０の薄肉状の延伸部２４８は、成形品本体２１の凸角縁２６に沿って互いにほぼ平行に複数条をなして形成されることが望ましい。この場合、離型紙４０（２４０）の折り曲げ方向への引張応力の発生を複数条の分離部４２又は薄肉状の延伸部２４８で良好に防止することができるため、離型紙４０（２４０）の復元力を減少させ、離型紙４０（２４０）の部分的な剥がれをさらに効果的に防止することができる。 In addition, this invention is not limited to the said Examples 1-3, In the range which does not deviate from the summary of this invention, it can also be implemented with a various form.
For example, the separation portion 42 of the release paper 40 of the first embodiment or the thin-walled extending portion 248 of the release paper 240 of the third embodiment has a plurality of strips substantially parallel to each other along the convex edge 26 of the molded product body 21. It is desirable to form. In this case, since the generation of tensile stress in the folding direction of the release paper 40 (240) can be satisfactorily prevented by the plurality of separation portions 42 or the thin-walled extending portions 248, the restoration of the release paper 40 (240). The force can be reduced, and partial peeling of the release paper 40 (240) can be more effectively prevented.
