Description

【0001】
【発明の属する技術分野】
本発明は、主として瓶や合成樹脂製容器の口部に装着される上部に天板を有する熱収縮性キャップシールに関する。
【0002】
【従来の技術】
従来、例えば瓶や合成樹脂製の容器の口部に安全性や密封性を高めるために密着して装着されるキャップシールAは、図4(イ)に示すように、熱収縮性を有する筒状フィルムからなるキャップシール本体20の上部を屈曲して上端部21を形成し、該上端部21には、シート22の外面に着色インキ層の印刷層23が設けられてなる天板24が熱シールにより接着されているものが公知である。
【0003】
そして、上記キャップシールAは、同図(ロ)に示すように、瓶や合成樹脂製容器の口部25に被嵌された後に、熱収縮により装着される。
【0004】
【発明が解決しようとする課題】
このようなキャップシールAの天板24は、シート22の外面全面に着色インキ層の印刷層23が設けられているため、着色インキ層の印刷層23がダンボール箱等との摩耗により、インキが剥がれる等の問題があった。このため、印刷層23を摩耗等から保護すべく、シート22の内面全面に該印刷層23を形成するようにしているが、天板24は印刷層23を介してキャップシール本体20に熱シールされる構成であるため、天板24の熱シール時に、印刷層23に含有されているインキの樹脂のシートに対するシール性が低下し、シートが不用意に剥離してしまうおそれがあった。
【0005】
本発明は、上記従来の問題点に鑑みてなされたもので、着色インキ層を裏面に有する天板とキャップシール本体との接着強度を増大でき、天板が不用意に剥離するのを防止することを課題とする。
【0006】
【課題を解決するための手段】
本発明は上記課題を解決するためになされたもので、熱収縮性を有する筒状フィルムからなるキャップシール本体1の上部を屈曲して上端部3を形成し、該上端部3には、シート5の内面に着色インキ層7が設けられてなる天板6が熱シールにより接着されている熱収縮性キャップシールにおいて、前記シート5の外周部5aには、前記着色インキ層7が設けられていない接着部分が設けられ、該接着部分が前記キャップシール本体1の上端部3に熱シールされてなり、前記キャップシール本体1の内面には、着色インキ層2が設けられ、前記天板6側の着色インキ層7の直径D1は、外周部においてシート面を露出するように、天板6の直径Dよりも小さく、且つ、前記上端部3の内径D2よりも大きく設定されており、天板6側の着色インキ層7とキャップシール本体1側の着色インキ層2とは、互いの縁部が重合していることにある。
【0007】
従って、本発明の熱収縮性キャップシールは、シート5の外周部5aの接着部分を直接キャップシール本体1に接触させて熱シールすることとなり、着色インキ層を介していないため、シート5とキャップシール本体1とのシール強度が向上する。
【0008】
また、前記天板6の直径Dと着色インキ層2の直径D1との寸法差は、2乃至10 mm であることにある。
【0009】
しかも、前記天板6の接着部分の内面には、前記キャップシール本体1側に対して熱シール性を有するコーティング層9,13が設けられていることにある。
【0010】
【発明の実施の形態】
第1実施の形態
以下、本発明の第1実施の形態を図面に従って説明する。
図1において、1は熱収縮性を有する筒状のキャップシール本体で、該キャップシール本体1は、厚さ30〜100 μm程度で且つ透明又は半透明の塩化ビニルよりなる横一軸延伸フィルムの横方向を周方向として筒状に形成されている。
【0011】
該キャップシール本体1は上端部3が内側に折曲され、且つ側周部4は下方に向かって径がやや広がったテーパー状に予備成形されたものである。しかも、キャップシール本体1の断面形状は円形を呈しているが、該キャップシール本体1が装着される容器の口部の形状に応じて、楕円又は矩形状を呈するものであっても良い。
【0012】
また、該キャップシール本体1の側周部4及び上端部3の内面には、商品名や任意のデザイン等を示す表示印刷層(図示せず)及び略全面を着色する着色インキ層2が全面に設けられている。
【0013】
6は前記キャップシール本体1の上端部3の上面に接着される円形の天板で、厚さ50〜200 μm程度で且つ透明又は半透明の軟質塩化ビニルシート(以下、シートという。)5と、該シート5の裏面に設けられた着色インキ層7とからなる。
【0014】
該着色インキ層7は、前記キャップシール本体1側の着色インキ層2と略同色で、その直径D1は、天板6の外周部5aにおいてシート面を露出するように、天板6の直径Dによりも小さく、且つ、上端部3の内径D2よりも大きく設定されている。従って、天板6はその外周部5aの全周が接着部分となり、外周部5aはキャップシール本体1の上端部3の表面に熱シールにより直接接着され、天板6側の着色インキ層7とキャップシール本体1側の着色インキ層2とは、互いの縁部が重合した状態となっている。
【0015】
尚、前記天板6の直径Dと着色インキ層2の直径D1との寸法差は、2〜10mm程度が好ましく、2mmより小さいは接着強度が弱くなる恐れがあると共に、天板6の製造時に広幅のシートから円形の天板6を打ち抜く作業性が悪くなる。また、10mmをこえる場合はキャップシール本体1の上端部を大きく収縮させることとなるため、製造が困難になる。
【0016】
8はキャップシール本体1の上部に形成された破断用の摘み部で、その両側にはミシン目8aが刻設され、しかも、両ミシン目8aの下端には、キャップシール本体1の周方向にミシン目8bが刻設されている。
【0017】
上記構成のキャップシールは、容器の口部に被嵌された後に熱収縮されて、容器の口部の表面形状に沿って密着状態で装着されるのであるが、上記の如く着色インキ層2,7の縁部同士が、互いに重合しているため、天板6とキャップシール本体1との接合部分で印刷が途切れたりすることはなく、キャップシール全面に印刷を施すことが可能となる。
【0018】
しかも、天板6とキャップシール本体1との接着に際しては、天板6の外周部5aを、直接にキャップシール本体1の上端部3に熱シールしているため、無印刷である外周部5aにおいて、着色インキ層7のインキの樹脂のシール性が加熱により低下するという欠点はなく、天板6をキャップシール本体1に強固に接着することができる。
【0019】
尚、キャップシール本体1は、前記以外にポリエステル、ポリプロピレン、ポリスチレン、ポリエチレン等の材質の熱収縮性フィルムまたはチューブが採用可能であり、また、天板6のシート5は、前記以外にポリエチレン、ポリプロピレン、ポリスチレン、ポリエステル、アクリル系樹脂等の材質の実質上非熱収縮性のシートが採用可能である。例えば、天板6とキャップシール本体1とが異質の材質からなるために熱シール性がない場合には、図2(ロ)に示す如くシート5の外周部5a及び着色インキ層7の内面に、キャップシール本体1との熱シール性を有するコーティング層9を設けることも可能である。
尚、コーティング層9としては、エチレン酢酸ビニル共重合体、エチレンアクリル酸共重合体、塩素化ポリプロピレン、酢酸ビニル樹脂等を主成分とした熱融着性接着剤やこれらの樹脂を含有した透明メジウムインキ等が使用できる。
【0020】
第2実施の形態
図3(イ)は本発明の第2実施の形態を示し、前記キャップシール本体1の側周部4及び上端部3の外面には、マット印刷(艶消し印刷)10が施され、しかも、天板6のシート5の表面にも同様にマット印刷11が施されている。
【0021】
また、天板6のシート5の外周部5a及び着色インキ層7の内面には、キャップシール本体1側のマット印刷10に対して熱シール性を有する熱接着性樹脂のコーティング層13(コーティング層9に例示したもの等より適宜選択できる)が全面に設けられており、天板6の外周部5aは、このコーティング層13を介してキャップシール本体1のマット印刷10面に熱シールされている。かかる場合にも、天板6の外周部5aはキャップシール本体1の上端部3に強固に接着されることとなる。
【0022】
尚、上記それぞれの実施の形態においては、シート5の外周部5aの全周を露出することにより、接着部分を形成したが、シート5とキャップシール本体1とのシール強度が得られる場合には、図3(ロ)に示す如く、必ずしもシート5の外周部5a全周を露出させる必要はない。
【0023】
【発明の効果】
本発明は、天板のシートの外周部には、前記着色インキ層が設けられていない接着部分が設けられ、該接着部分が前記キャップシール本体の上端部に熱シールされているので、着色インキ層がシートの内面に設けられているにもかかわらず、天板とキャップシール本体との接着強度を増大でき、天板が剥離するのを効果的に防止することができる。
【0024】
また、キャップシール本体1の内面に着色インキ層が設けられ、しかも、前記天板側の着色インキ層の直径は、外周部においてシート面を露出するように、天板の直径よりも小さく、且つ、前記上端部の内径よりも大きく設定されている場合には、両方の着色インキ層の縁部同士を、互いに重合させることが可能となり、天板とキャップシール本体との接合部分で印刷が途切れたりすることはなく、キャップシール全面に印刷を施すことが可能となる利点がある。

BACKGROUND OF THE INVENTION
The present invention mainly relates to a heat-shrinkable cap seal having a top plate on the upper part attached to the mouth of a bottle or a synthetic resin container.
[0002]
[Prior art]
Conventionally, for example, a cap seal A that is closely attached to a mouth portion of a bottle or a synthetic resin container in order to enhance safety and sealing performance is a tube having heat shrinkability as shown in FIG. An upper end 21 is formed by bending the upper part of the cap seal body 20 made of a film-like film, and a top plate 24 formed by providing a printed layer 23 of a colored ink layer on the outer surface of the sheet 22 is heated. Those bonded by a seal are known.
[0003]
The cap seal A is attached by thermal contraction after being fitted into the mouth 25 of a bottle or a synthetic resin container, as shown in FIG.
[0004]
[Problems to be solved by the invention]
Since the top plate 24 of the cap seal A is provided with a colored ink layer printing layer 23 on the entire outer surface of the sheet 22, the colored ink layer printing layer 23 is worn by a corrugated cardboard box or the like. There was a problem such as peeling off. Therefore, in order to protect the printing layer 23 from abrasion and the like, the printing layer 23 is formed on the entire inner surface of the sheet 22, but the top plate 24 is heat-sealed to the cap seal body 20 via the printing layer 23. Therefore, when the top plate 24 is heat-sealed, the sealing performance of the ink resin contained in the printing layer 23 with respect to the resin sheet is lowered, and the sheet may be inadvertently peeled off.
[0005]
The present invention has been made in view of the above-described conventional problems, and can increase the adhesive strength between the top plate having the colored ink layer on the back surface and the cap seal body, thereby preventing the top plate from being carelessly peeled off. This is the issue.
[0006]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-mentioned problems, and an upper end portion 3 is formed by bending an upper portion of a cap seal main body 1 made of a heat-shrinkable tubular film. In the heat-shrinkable cap seal in which the top plate 6 having the colored ink layer 7 provided on the inner surface of the sheet 5 is bonded by heat sealing, the colored ink layer 7 is provided on the outer peripheral portion 5a of the sheet 5. A non-adhesive portion is provided, and the adhesive portion is heat-sealed to the upper end portion 3 of the cap seal body 1, and a colored ink layer 2 is provided on the inner surface of the cap seal body 1, and the top plate 6 side The diameter D1 of the colored ink layer 7 is set to be smaller than the diameter D of the top plate 6 and larger than the inner diameter D2 of the upper end portion 3 so as to expose the sheet surface at the outer peripheral portion. 6 side coloring The key layer 7 and the colored ink layer 2 of the cap seal body 1 side is that the edges of each other are polymerized.
[0007]
Therefore, the heat-shrinkable cap seal of the present invention heat-seals the contact portion of the outer peripheral portion 5a of the sheet 5 directly in contact with the cap seal body 1 and does not involve a colored ink layer. The seal strength with the seal body 1 is improved.
[0008]
The dimensional difference between the diameter D and the diameter D1 of the colored ink layer 2 of the top plate 6 is that it is 2 to 10 mm.
[0009]
In addition, coating layers 9 and 13 having heat sealing properties with respect to the cap seal body 1 side are provided on the inner surface of the bonding portion of the top plate 6.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a cylindrical cap seal body having heat shrinkability. The cap seal body 1 has a thickness of about 30 to 100 μm and a horizontal uniaxially stretched film made of transparent or translucent vinyl chloride. It is formed in a cylindrical shape with the direction as the circumferential direction.
[0011]
The cap seal main body 1 is preliminarily formed into a tapered shape with the upper end portion 3 bent inward and the side peripheral portion 4 having a diameter slightly expanded downward. Moreover, although the cross-sectional shape of the cap seal body 1 is circular, it may be oval or rectangular depending on the shape of the mouth of the container to which the cap seal body 1 is attached.
[0012]
In addition, a display printing layer (not shown) indicating a trade name, an arbitrary design, and the like, and a colored ink layer 2 for coloring substantially the entire surface are provided on the inner surfaces of the side peripheral portion 4 and the upper end portion 3 of the cap seal body 1. Is provided.
[0013]
Reference numeral 6 denotes a circular top plate adhered to the upper surface of the upper end portion 3 of the cap seal body 1, and a transparent or translucent soft vinyl chloride sheet (hereinafter referred to as a sheet) 5 having a thickness of about 50 to 200 μm. , And a colored ink layer 7 provided on the back surface of the sheet 5.
[0014]
The colored ink layer 7 is substantially the same color as the colored ink layer 2 on the cap seal body 1 side, and the diameter D1 of the top plate 6 is such that the sheet surface is exposed at the outer peripheral portion 5a of the top plate 6. And larger than the inner diameter D2 of the upper end 3. Accordingly, the entire periphery of the outer peripheral portion 5a of the top plate 6 becomes an adhesive portion, and the outer peripheral portion 5a is directly bonded to the surface of the upper end portion 3 of the cap seal body 1 by heat sealing, and the colored ink layer 7 on the top plate 6 side. The colored ink layer 2 on the cap seal body 1 side is in a state in which the edges of each other are polymerized.
[0015]
In addition, the dimensional difference between the diameter D of the top plate 6 and the diameter D1 of the colored ink layer 2 is preferably about 2 to 10 mm, and if it is less than 2 mm, the adhesive strength may be weakened. The workability of punching the circular top plate 6 from a wide sheet deteriorates. Further, when the length exceeds 10 mm, the upper end portion of the cap seal main body 1 is greatly contracted, which makes it difficult to manufacture.
[0016]
Reference numeral 8 denotes a breaking knob formed on the upper part of the cap seal body 1, and perforations 8a are formed on both sides thereof, and at the lower ends of the two perforations 8a, the cap seal body 1 is provided in the circumferential direction. Perforation 8b is engraved.
[0017]
The cap seal having the above structure is heat-shrinked after being fitted to the mouth of the container, and is attached in close contact with the surface shape of the mouth of the container. Since the edges of 7 are superposed on each other, printing is not interrupted at the joint between the top plate 6 and the cap seal body 1, and printing can be performed on the entire surface of the cap seal.
[0018]
In addition, when the top plate 6 and the cap seal body 1 are bonded, the outer peripheral portion 5a of the top plate 6 is directly heat-sealed to the upper end portion 3 of the cap seal main body 1, so that the outer peripheral portion 5a that is not printed. In this case, there is no disadvantage that the sealing property of the resin of the ink of the colored ink layer 7 is lowered by heating, and the top plate 6 can be firmly bonded to the cap seal body 1.
[0019]
In addition, the cap seal body 1 can employ a heat-shrinkable film or tube made of polyester, polypropylene, polystyrene, polyethylene, or the like other than the above, and the sheet 5 of the top plate 6 can be made of polyethylene, polypropylene, or the like. A substantially non-heat-shrinkable sheet made of polystyrene, polyester, acrylic resin or the like can be used. For example, when the top plate 6 and the cap seal body 1 are made of different materials and thus have no heat sealability, the outer peripheral portion 5a of the sheet 5 and the inner surface of the colored ink layer 7 are formed as shown in FIG. It is also possible to provide a coating layer 9 having heat sealing properties with the cap seal body 1.
The coating layer 9 includes a heat-fusible adhesive mainly composed of an ethylene vinyl acetate copolymer, an ethylene acrylic acid copolymer, a chlorinated polypropylene, a vinyl acetate resin, or a transparent medium containing these resins. Ink can be used.
[0020]
Second Embodiment FIG. 3 (a) shows a second embodiment of the present invention, in which mat printing (matte) is applied to the outer surfaces of the side peripheral portion 4 and the upper end portion 3 of the cap seal body 1. (Printing) 10 is applied, and the mat printing 11 is similarly applied to the surface of the sheet 5 of the top plate 6.
[0021]
Further, on the outer peripheral portion 5a of the sheet 5 of the top plate 6 and the inner surface of the colored ink layer 7, a coating layer 13 (coating layer) of a heat-adhesive resin having a heat sealing property with respect to the mat print 10 on the cap seal body 1 side. The outer peripheral portion 5a of the top plate 6 is heat-sealed to the mat print 10 surface of the cap seal body 1 through the coating layer 13. . Even in such a case, the outer peripheral portion 5 a of the top plate 6 is firmly bonded to the upper end portion 3 of the cap seal body 1.
[0022]
In each of the above embodiments, the adhesive portion is formed by exposing the entire circumference of the outer peripheral portion 5a of the sheet 5. However, when the sealing strength between the sheet 5 and the cap seal body 1 can be obtained. As shown in FIG. 3B, it is not always necessary to expose the entire outer periphery 5a of the sheet 5.
[0023]
【The invention's effect】
In the present invention, the outer peripheral portion of the sheet of the top plate is provided with an adhesive portion not provided with the colored ink layer, and the adhesive portion is heat sealed to the upper end portion of the cap seal body. Although the layer is provided on the inner surface of the sheet, the adhesive strength between the top plate and the cap seal body can be increased, and the top plate can be effectively prevented from peeling off.
[0024]
Further, a colored ink layer is provided on the inner surface of the cap seal body 1, and the diameter of the colored ink layer on the top plate side is smaller than the diameter of the top plate so that the sheet surface is exposed at the outer peripheral portion, and If the inner diameter of the upper end is set larger than the inner diameter, the edges of both colored ink layers can be polymerized with each other, and printing is interrupted at the joint between the top plate and the cap seal body. There is an advantage that the entire surface of the cap seal can be printed.
