特開2009−297909JP-A-2009-297909

特許文献1などで、従来から、接着用粘着剤塗膜を転写する糊転写テープ用の塗膜転写具が開示されている。修正テープ用の塗膜転写具では、転写ヘッドには一般的にヘラ状の転写ヘッドが用いられている。ヘラ状の転写ヘッドを使用することで、修正テープを被転写面に転写後に、転写した修正テープ塗膜と塗膜転写具の転写テープ上に残った修正テープ塗膜とを切断しやすくすること、すなわち修正テープ塗膜の“切れ性”を良好なものとすることができる。修正テープ塗膜の“切れ性”を良好なものとすることにより、使用者が良好な使用感で塗膜転写具を使用することができるとともに、被転写面に転写された修正テープ塗膜の終端を見た目に美しいものとすることができる。 Patent Document 1 and the like have conventionally disclosed a coating film transfer tool for a glue transfer tape that transfers an adhesive coating film for adhesion. In the coating film transfer tool for correction tape, a spatula-shaped transfer head is generally used as the transfer head. By using a spatula-shaped transfer head, after transferring the correction tape to the surface to be transferred, it is easy to cut the transferred correction tape coating film and the correction tape coating film remaining on the transfer tape of the coating film transfer tool. That is, the "cutability" of the correction tape coating film can be improved. By improving the "cutting property" of the correction tape coating film, the user can use the coating film transfer tool with a good feeling of use, and the correction tape coating film transferred to the surface to be transferred can be used. The end can be visually beautiful.

これに対して、糊転写テープ用の塗膜転写具では、ヘラ状の転写ヘッドよりも、回転するローラで塗膜を被転写面に押し当てて転写するローラ状の転写ヘッドが多く使用されている。糊転写テープ用の塗膜転写具でも、転写ヘッドにヘラ状のヘッドを用いると、修正テープの場合と同様に、転写された塗膜である接着用粘着剤塗膜の切れ性は良い。しかしながら、接着用粘着剤塗膜がヘラで押しつぶされた状態で被転写面に転写されるため、転写された接着用粘着剤塗膜の接着力が低下するという問題がある。修正テープは、文字などを修正テープの塗膜で覆い隠すことだけで、その使用目的が達成されるのに対して、糊転写テープでは、転写した接着用粘着剤塗膜が、さらに他の紙等との接着に供されるため、転写された接着用粘着剤塗膜の接着力の維持は最も優先される機能である。このため、糊転写テープ用の塗膜転写具では、接着用粘着剤塗膜の接着力を考慮し、ローラ状の転写ヘッドを使用することが多くなっている。 On the other hand, in the coating film transfer tool for glue transfer tape, a roller-shaped transfer head that transfers the coating film by pressing it against the surface to be transferred by a rotating roller is more often used than a spatula-shaped transfer head. There is. Even in the coating film transfer tool for glue transfer tape, when a spatula-shaped head is used for the transfer head, the cutability of the adhesive coating film for adhesion, which is the transferred coating film, is good as in the case of correction tape. However, since the adhesive coating film for adhesion is transferred to the surface to be transferred in a state of being crushed by a spatula, there is a problem that the adhesive force of the transferred adhesive adhesive coating film for adhesion is lowered. In correction tape, the purpose of use is achieved simply by covering characters with a coating film of correction tape, whereas in glue transfer tape, the transferred adhesive coating film for adhesive is used on other papers. Maintaining the adhesive strength of the transferred adhesive coating film for adhesion is the highest priority function because it is used for adhesion to the like. For this reason, in the coating film transfer tool for glue transfer tape, a roller-shaped transfer head is often used in consideration of the adhesive force of the adhesive coating film for adhesion.

このように、従来の糊転写テープ用の塗膜転写具では、転写された塗膜である接着用粘着剤塗膜の切れ性と、転写された接着用粘着剤塗膜の接着力の維持が両立された塗膜転写具がなかった。 As described above, in the conventional coating film transfer tool for glue transfer tape, the breakability of the adhesive coating film for adhesion, which is the transferred coating film, and the adhesive strength of the transferred adhesive coating film for adhesion can be maintained. There was no compatible coating film transfer tool.

本発明は前記のような従来の塗膜転写具の問題点に鑑みてなされたものであって、本発明が解決しようとする課題は、従来のヘラ状ヘッドとローラ状ヘッドがそれぞれに有していた課題を解決して、転写後の接着用粘着剤塗膜の接着性と転写時の接着用粘着剤塗膜の切れ性を両立した糊転写テープ用の塗膜転写具を提供することである。 The present invention has been made in view of the above-mentioned problems of the conventional coating transfer tool, and the problems to be solved by the present invention are inherent in the conventional spatula-shaped head and the roller-shaped head. By solving the problems that have been occurring, by providing a coating transfer tool for glue transfer tape that has both the adhesiveness of the adhesive coating film after transfer and the cutting property of the adhesive coating film during transfer. is there.

第1発明は、基材テープに接着用粘着剤塗膜を設けた糊転写テープの前記接着用粘着剤塗膜を被転写面に転写するための塗膜転写具であって、前記糊転写テープを繰出す繰出し部、前記糊転写テープを前記被転写面に押圧して前記接着用粘着剤塗膜を前記被転写面に転写する転写押圧部、前記接着用粘着剤塗膜を転写後の前記基材テープを巻き取る巻取り部、及び前記繰出し部と前記巻取り部を連動回転させる連動回転部を有し、前記転写押圧部には、前記糊転写テープを押圧して前記接着用粘着剤塗膜を前記被転写面に転写する転写ローラが回転可能に設けられ、前記転写ローラの外周のうち、少なくとも前記糊転写テープを押圧する部分全面にわたって、複数の突起が設けられ、前記複数の突起が前記転写ローラの外周方向に等間隔に設けられ、前記複数の突起が前記転写ローラの回転軸方向に等間隔に設けられていることを特徴とする糊転写テープ用の塗膜転写具である。 The first invention is a coating transfer tool for transferring the adhesive coating film for adhesion of a glue transfer tape having an adhesive coating film for adhesion on a base material tape to the surface to be transferred, and the glue transfer tape. The transfer pressing portion that feeds out the adhesive, the adhesive transfer tape is pressed against the surface to be transferred, and the adhesive coating film for adhesion is transferred to the surface to be transferred, and the adhesive coating film for adhesion is transferred to the surface. It has a winding portion for winding the base material tape, and an interlocking rotating portion for interlocking rotation of the feeding portion and the winding portion, and the transfer pressing portion presses the glue transfer tape to provide the adhesive adhesive. transfer rollers for transferring a coating film on the transferred surface is rotatably provided, of the outer periphery of the transfer roller, over the portion entirely for pressing at least the glue transfer tape, a plurality of projections are provided, the plurality of projections there is provided at equal intervals in the outer circumferential direction of the transfer roller is the coating film transfer tool for glue transfer tape, wherein the plurality of protrusions are provided at equal intervals in the rotational axis direction of said transfer roller ..

第2発明は、前記複数の突起先端の面積が0.5mm以下であることを特徴とする第1発明に記載の糊転写テープ用の塗膜転写具である。 The second invention is the coating film transfer tool for glue transfer tape according to the first invention, wherein the area of the plurality of protrusion tips is 0.5 mm 2 or less.

第3発明は、前記複数の突起先端の間隔が0.2mm以上、かつ0.7mm以下であることを特徴とする第1又は第2発明に記載の糊転写テープ用の塗膜転写具である。 The third invention is the coating film transfer tool for glue transfer tape according to the first or second invention, wherein the distance between the tips of the plurality of protrusions is 0.2 mm or more and 0.7 mm or less. ..

本発明の塗膜転写具では、塗膜転写時に回転するローラ状の転写ヘッドを使用しているので、転写時に接着用粘着剤塗膜が押しつぶされることがほとんどなく、転写後の接着用粘着剤塗膜の接着力が低下しない。また、ローラ外周に設けた複数の突起が起点となって接着用粘着剤塗膜が切れるので、接着用粘着剤塗膜の切れ性が向上する。したがって、従来のヘラ状ヘッドとローラ状ヘッドがそれぞれに有していた課題を解決して、転写後の接着用粘着剤塗膜の接着性と転写時の接着用粘着剤塗膜の切れ性を両立した糊転写テープ用の塗膜転写具を提供することができる。 Since the coating film transfer tool of the present invention uses a roller-shaped transfer head that rotates during coating film transfer, the adhesive coating film is hardly crushed during transfer, and the adhesive adhesive after transfer is used. The adhesive strength of the coating film does not decrease. Further, since the adhesive coating film for adhesion is cut from the plurality of protrusions provided on the outer periphery of the roller, the cutting property of the adhesive coating film for adhesion is improved. Therefore, by solving the problems that the conventional spatula-shaped head and roller-shaped head have, respectively, the adhesiveness of the adhesive coating film for adhesion after transfer and the breakability of the adhesive coating film for adhesion during transfer can be improved. It is possible to provide a coating film transfer tool for a compatible glue transfer tape.

本発明の第1実施形態の塗膜転写具Aを図1に示す。図1(a)はカバーを除去した状態の塗膜転写具Aの正面図であり、図1(b)は塗膜転写具Aのカバーをセットした状態の底面図である。図2は、転写ローラ7単体を示す図である。 The coating film transfer tool A of the first embodiment of the present invention is shown in FIG. FIG. 1A is a front view of the coating film transfer tool A with the cover removed, and FIG. 1B is a bottom view of the coating film transfer tool A with the cover set. FIG. 2 is a diagram showing a single transfer roller 7.

塗膜転写具Aは、図1に示すようにケ−ス1とカバー2からなる筐体、基材テープT1に接着用粘着剤塗膜を塗布した糊転写テ−プTを繰出しコア3に巻きまわした繰出し側パンケーキ、接着用粘着剤塗膜を紙等の被転写面に転写する転写ローラ7を回転可能に保持する転写ヘッド4、接着用粘着剤塗膜を転写した後の基材テ−プT1を巻取る巻取りコア5、及び繰出しコア3の回転を巻取りコア5に伝えるOリング6から構成されるものである。 As shown in FIG. 1, the coating film transfer tool A is a housing composed of a case 1 and a cover 2, and a glue transfer tape T having an adhesive coating film applied to a base material tape T1 is fed to a feeding core 3. The roll-out side pancake, the transfer head 4 that rotatably holds the transfer roller 7 that transfers the adhesive coating film to the surface to be transferred such as paper, and the base material after the adhesive coating film is transferred. It is composed of a take-up core 5 for winding the tape T1 and an O-ring 6 for transmitting the rotation of the take-out core 3 to the take-up core 5.

しかしながら、本発明に係る塗膜転写具は、これに限定されるものではなく、糊転写テープが繰出し側のパンケーキ(繰出し部)から繰出され、転写ローラで糊転写テープから接着用粘着剤塗膜が被転写面に転写され、接着用粘着剤塗膜を転写した残りの基材テープが巻取り部で巻取られる形態であれば、任意の形態とすることができる。 However, the coating film transfer tool according to the present invention is not limited to this, and the glue transfer tape is fed from the pancake (feeding portion) on the feeding side, and the adhesive is applied from the glue transfer tape by the transfer roller. Any form can be used as long as the film is transferred to the surface to be transferred and the remaining base material tape on which the adhesive coating film for adhesion is transferred is wound by the winding portion.

塗膜転写具Aでは、ケース1とカバー2に保持された転写ヘッド4に、転写ローラ7が回転可能に保持されているが、転写ヘッド4を介さず、ケース1とカバー2が直接、転写ローラ7を回転可能に保持する形態としてもよい。 In the coating film transfer tool A, the transfer roller 7 is rotatably held by the transfer head 4 held by the case 1 and the cover 2, but the case 1 and the cover 2 are directly transferred without passing through the transfer head 4. The roller 7 may be held rotatably.

転写ローラ7は、概ね円柱状の部材であり、当該円柱状の側面に相当する面(外周面)で糊転写テープTを被転写面に押圧し、接着用粘着剤塗膜を被転写面に転写する。 The transfer roller 7 is a substantially columnar member, and the glue transfer tape T is pressed against the transfer surface on the surface (outer peripheral surface) corresponding to the side surface of the column, and the adhesive coating film for adhesion is applied to the transfer surface. Transfer.

塗膜転写具Aでは、転写ローラ7が回転しつつ、糊転写テープTを被転写面に押圧して、接着用粘着剤塗膜を紙等の被転写面に転写する。このため、塗膜転写具Aを使用して転写した接着用粘着剤塗膜は、ヘラ状の転写ヘッドで転写した接着用粘着剤塗膜のように転写時に押しつぶされることがほとんどなく、接着力が低下しない。 In the coating film transfer tool A, the transfer roller 7 rotates and presses the glue transfer tape T against the surface to be transferred to transfer the adhesive coating film for adhesion to the surface to be transferred such as paper. Therefore, the adhesive coating film for adhesion transferred using the coating film transfer tool A is hardly crushed at the time of transfer unlike the adhesive coating film for adhesion transferred by the spatula-shaped transfer head, and has adhesive strength. Does not decrease.

また、図2に示すように、転写ローラ7の外周には、少なくとも糊転写テープTを押圧する部分全面にわたって、複数の突起を設けている。塗膜転写具Aで、糊転写テープTを被転写面に押圧して、接着用粘着剤塗膜を紙等の被転写面に転写すると、これらの複数の突起で被転写面に押圧された部分から、接着用粘着剤塗膜が破断するので、従来の転写ローラを使用した塗膜転写具にくらべて、被転写面への転写時の接着用粘着剤塗膜の切れ性が良好となる。 Further, as shown in FIG. 2, a plurality of protrusions are provided on the outer periphery of the transfer roller 7 at least over the entire surface of the portion that presses the glue transfer tape T. When the adhesive transfer tape T was pressed against the surface to be transferred with the coating film transfer tool A to transfer the adhesive coating film for adhesion to the surface to be transferred such as paper, the adhesive coating film was pressed against the surface to be transferred by these plurality of protrusions. Since the adhesive coating film for adhesion is broken from the portion, the cutting property of the adhesive coating film for adhesion at the time of transfer to the surface to be transferred is improved as compared with the coating film transfer tool using the conventional transfer roller. ..

転写ローラ7の材料には、金属、プラスチック等を用いることができる。転写ローラ7の外周に設ける複数の突起の耐久性、並びに接着用粘着剤塗膜の切れ性を考慮すると、硬度が高い材料が好ましく、具体的には、鉄、アルミニウム、ポリアセタール、ポリカーボネート等が好ましい。生産性を考慮すると、射出成形等で生産できるプラスチック材料の使用が好ましい。 As the material of the transfer roller 7, metal, plastic or the like can be used. Considering the durability of the plurality of protrusions provided on the outer periphery of the transfer roller 7 and the breakability of the adhesive coating film for adhesion, a material having high hardness is preferable, and specifically, iron, aluminum, polyacetal, polycarbonate and the like are preferable. .. Considering productivity, it is preferable to use a plastic material that can be produced by injection molding or the like.

転写ローラ7の外周に設ける複数の突起の形状には特に制限はないが、突起が被転写面への押圧力に押しつぶされることがないなどの耐久性を考慮すると、少なくとも先端と根元が同形状であるか、或いは、根元に向かって広がる円錐や角錐等の形状が好ましい。 The shape of the plurality of protrusions provided on the outer circumference of the transfer roller 7 is not particularly limited, but at least the tip and the root have the same shape in consideration of durability such that the protrusions are not crushed by the pressing force on the transfer surface. Or, a shape such as a cone or a pyramid that spreads toward the root is preferable.

塗膜転写具Aでは、複数の突起の先端に押圧力が集中することによって、複数の突起の先端が起点となって接着用粘着剤塗膜が切れて、接着用粘着剤塗膜の切れ性が向上する。このため、複数の突起の先端の面積が大きすぎると、複数の突起の先端に押圧力が十分に集中せず、接着用粘着剤塗膜の切れ性が十分に向上しない。図2に示す複数の突起の先端の面積Jは0.5mm以下が好ましく、0.3mm以下がより好ましい。転写ローラ7の材質がポリアセタール等のプラスチックの場合には、複数の突起先端の面積が0.07mm未満になると、塗膜転写時に複数の突起先端が押しつぶされやすくなる。複数の突起先端が押しつぶされると、複数の突起の高さが低くなることによって、接着用粘着剤塗膜の切れ性が低下する。このため、転写ローラ7の材質がポリアセタール等のプラスチックの場合には、複数の突起先端の面積は、0.07mm以上が、好ましい。 In the coating film transfer tool A, when the pressing force is concentrated on the tips of the plurality of protrusions, the adhesive coating film for adhesion is cut off from the tips of the plurality of protrusions, and the adhesive coating film is cut off. Is improved. Therefore, if the area of the tips of the plurality of protrusions is too large, the pressing force is not sufficiently concentrated on the tips of the plurality of protrusions, and the breakability of the adhesive coating film for adhesion is not sufficiently improved. A plurality of area J of the tip of the projection is preferably 0.5 mm 2 or less as shown in FIG. 2, and more preferably 0.3 mm 2 or less. When the material of the transfer roller 7 is plastic such as polyacetal, if the area of the tips of the plurality of protrusions is less than 0.07 mm 2, the tips of the plurality of protrusions are likely to be crushed during the transfer of the coating film. When the tips of the plurality of protrusions are crushed, the height of the plurality of protrusions is lowered, so that the breakability of the adhesive coating film for adhesion is lowered. Therefore, when the material of the transfer roller 7 is plastic such as polyacetal, the area of the tips of the plurality of protrusions is preferably 0.07 mm 2 or more.

複数の突起先端は、0.2mm以上、かつ0.7mm以下の間隔で設けられていることが好ましく、0.2mm以上、かつ0.4mm以下の間隔で設けられていることがより好ましい。複数の突起先端の間隔Kが0.2mm未満になると、複数の突起先端の密度が大きくなり、転写ロール表面に突起がない平滑な状態に近づくため、複数の突起により接着用粘着剤塗膜を破断する効果が低下する。一方、複数の突起先端の間隔Kが0.7mmを超えると、接着用粘着剤塗膜切れ性が十分に向上しない。本発明の複数の突起先端の間隔Kは、図2に示すように、突起先端の外周と他の突起先端の外周との距離が最も近い位置における、突起先端の外周と他の突起先端の外周との距離を意味する。 The plurality of protrusion tips are preferably provided at intervals of 0.2 mm or more and 0.7 mm or less, and more preferably 0.2 mm or more and 0.4 mm or less. When the distance K between the tips of the plurality of protrusions is less than 0.2 mm, the density of the tips of the plurality of protrusions increases, and the surface of the transfer roll approaches a smooth state without protrusions. The effect of breaking is reduced. On the other hand, if the distance K between the tips of the plurality of protrusions exceeds 0.7 mm, the adhesive coating film breaking property for adhesion is not sufficiently improved. As shown in FIG. 2, the distance K between the plurality of protrusion tips of the present invention is the outer circumference of the protrusion tip and the outer circumference of the other protrusion tip at the position where the distance between the outer circumference of the protrusion tip and the outer circumference of the other protrusion tip is the closest. Means the distance to.

図2に示す複数の突起の根元からの高さLは、糊転写テープ全体の厚み、すなわち基材テープ厚みと接着用粘着剤塗膜厚みの合計よりも、0.1mm以上大きいことが好ましく、0.2mm以上大きいことがより好ましい。複数の突起の根元からの高さLが、糊転写テープ全体の厚みよりも0.1mm以上大きくないと、複数の突起による接着用粘着剤塗膜を破断する効果が十分に発揮されず、接着用粘着剤塗膜の切れ性が十分に向上しない。複数の突起の根元からの高さLが大きくなると、前記複数の突起先端の間隔Kも大きくなる。このため、複数の突起の根元からの高さLは、前記複数の突起先端の間隔Kが好ましい範囲の最大値よりも大きくならない値とすることが、好ましい。 The height L from the roots of the plurality of protrusions shown in FIG. 2 is preferably 0.1 mm or more larger than the total thickness of the glue transfer tape, that is, the total thickness of the base tape and the adhesive coating film for adhesion. It is more preferable that the size is 0.2 mm or more. Unless the height L from the roots of the plurality of protrusions is 0.1 mm or more larger than the thickness of the entire glue transfer tape, the effect of breaking the adhesive coating film for adhesion by the plurality of protrusions is not sufficiently exhibited and adhesion is performed. Adhesive for use The cuttability of the coating film is not sufficiently improved. As the height L from the roots of the plurality of protrusions increases, the distance K between the tips of the plurality of protrusions also increases. Therefore, it is preferable that the height L from the roots of the plurality of protrusions is a value such that the distance K between the tips of the plurality of protrusions does not become larger than the maximum value in the preferable range.

複数の突起は、転写ローラ7の外周方向に等間隔に設けられていることが好ましい。外周方向に等間隔に設けられることにより、転写ローラ7の外周上のどの位置でも、接着用粘着剤塗膜の切れ性がほぼ一定となり、使用者が良好な使用感で塗膜転写具を使用することができる。 It is preferable that the plurality of protrusions are provided at equal intervals in the outer peripheral direction of the transfer roller 7. By being provided at equal intervals in the outer peripheral direction, the cutting property of the adhesive coating film for adhesion becomes almost constant at any position on the outer circumference of the transfer roller 7, and the user can use the coating film transfer tool with a good feeling of use. can do.

また、複数の突起は、転写ローラ7の回転軸方向に等間隔に設けられていることが好ましい。回転軸方向に等間隔に設けられることにより、転写ローラ7の幅方向(回転軸方向)のどの位置でも、接着用粘着剤塗膜の切れ性がほぼ一定となり、接着用粘着剤塗膜の切れ性が安定する。 Further, it is preferable that the plurality of protrusions are provided at equal intervals in the rotation axis direction of the transfer roller 7. By being provided at equal intervals in the rotation axis direction, the breakability of the adhesive coating film for adhesion becomes almost constant at any position in the width direction (rotation axis direction) of the transfer roller 7, and the adhesive coating film for adhesion is cut. Sex is stable.

As the organic polymer film support, various film supports such as polyester film, polycarbonate film, polymethylmethacrylate film, polypropylene film, and polyimide film can be used, but polyester film is particularly preferable from the viewpoint of cost and performance. The film thickness of the film support is preferably in the range of 6 to 50 μm, more preferably 12 to 25 μm in terms of transferability and cost. Further, as the paper support, high-density paper such as glassine paper, clay-coated paper, laminated paper obtained by laminating a resin film such as polyethylene on kraft paper or high-quality paper can be used, but the cost and cost and From the viewpoint of performance, it is preferable to use glassine paper. The thickness of the paper support is preferably in the range of 20 to 50 μm.

なお、これらの支持体は、支持体両面の表面上にシリコーン化合物、フッ素樹脂、フルオロシリコーン樹脂などの離型剤を塗布することにより、両面が剥離性を有するシート(以下、剥離シートという場合がある)として使用するのが好ましい。 It should be noted that these supports are sheets having release properties on both sides by applying a release agent such as a silicone compound, fluororesin, or fluorosilicone resin on the surfaces of both sides of the support (hereinafter, may be referred to as a release sheet). It is preferable to use as (is).

塗膜転写具Aに使用する糊転写テープにおける接着用粘着剤塗膜の構成材料である粘着剤組成物は、特に限定されず、一般的な粘着剤組成物が使用可能であるが、アクリル系共重合体と架橋剤を必須成分とし、必要により、粘着付与樹脂を配合したものが好適に使用できる。 Adhesive Adhesive in Glue Transfer Tape Used for Coating Transfer Tool A The pressure-sensitive adhesive composition which is a constituent material of the coating film is not particularly limited, and a general pressure-sensitive adhesive composition can be used, but it is acrylic.
