Description

ジッパーテープ、ジッパーテープ付き容器および改ざん防止方法Zipper tape, container with zipper tape, and method for preventing tampering
　本発明は、ジッパーテープ、ジッパーテープ付き容器および改ざん防止方法に関する。 The present invention relates to a zipper tape, a container with a zipper tape, and a method for preventing tampering.
　例えば特許文献１に記載されているように、一度閉じられたジッパーの係合部が再び開くことを困難にすることによって、ジッパーテープ付き容器の内容物の改ざんを防止する技術が知られている。特許文献１の場合、内容物の封入前には、係合部が閉じてしまわないようにジッパーテープの間にフィルムが介挿される。 For example, as described in Patent Document 1, there is known a technique for preventing tampering with the contents of a container with a zipper tape by making it difficult to reopen the engaging portion of the zipper that has once been closed. . In the case of Patent Document 1, a film is interposed between the zipper tapes before enclosing the contents so that the engaging portion is not closed.
特開２０１５－２１７９８０号公報JP 2015-217980 A
　上記の特許文献１のような場合以外にも、ジッパーの係合部が閉じることを防止したい場合がある。例えば、係合部が開いた状態でジッパーテープ付き容器を搬送し、その後に内容物を封入して係合部を閉じるような場合、搬送中に係合部が閉じることを防止する必要がある。これらの場合において、係合部が閉じるのを防止するためにフィルムのような追加の部材を介挿するのは工程として煩雑であり、また一般的にフィルムはプラスチックで形成されるため、廃プラスチック削減の観点からも好ましくない。 In addition to the case described in Patent Document 1 above, there are cases where it is desired to prevent the engaging portion of the zipper from closing. For example, when a container with a zipper tape is transported with the engaging portion open, and then the contents are enclosed and the engaging portion is closed, it is necessary to prevent the engaging portion from closing during transportation. . In these cases, it is a complicated process to insert an additional member such as a film to prevent the engagement portion from closing, and since the film is generally made of plastic, waste plastic It is not preferable from the viewpoint of reduction.

It is a top view of the container with a zipper tape containing the zipper tape shown in FIG.
　図１は、本発明の一実施形態に係るジッパーテープの係合部を拡大した断面図である。図２は、比較のために、一般的なジッパーテープの係合部を拡大した断面図である。図１に示すジッパーテープ１０は、第１の基部１１と、第２の基部１２と、第１の基部１１から突出する雄型係合部１３Ａと、第２の基部１２から突出する雌型係合部１３Ｂとを含む。雄型係合部１３Ａは、外向きに突出する鉤部１５１，１５２を含む。より具体的には、鉤部１５１，１５２は、第１の基部１１から立ち上がる共通の立上部１５Ａと、立上部１５Ａから両側にそれぞれ突出する突出部１５１Ｂ，１５２Ｂとを含む。突出部１５２Ｂは、先端に形成される返し部１５２Ｂ２を含む。 FIG. 1 is an enlarged cross-sectional view of an engaging portion of a zipper tape according to one embodiment of the present invention. FIG. 2 is an enlarged cross-sectional view of an engaging portion of a general zipper tape for comparison. The zipper tape 10 shown in FIG. and joint portion 13B. The male engaging portion 13A includes hooks 151 and 152 projecting outward. More specifically, the hook portions 151 and 152 include a common rising portion 15A rising from the first base portion 11 and protruding portions 151B and 152B protruding from the rising portion 15A to both sides. The projecting portion 152B includes a return portion 152B2 formed at the tip.
　一方、雌型係合部１３Ｂは、内向きに突出する鉤部１５３，１５４を含む。より具体的には、鉤部１５３は、第２の基部１２から立ち上がる立上部１５３Ａと、立上部１５３Ａから突出する突出部１５３Ｂを含む。突出部１５３Ｂは、立上部１５３Ａに続いて形成される屈曲部１５３Ｂ１と、屈曲部１５３Ｂ１の先端に形成される返し部１５３Ｂ２とを含む。鉤部１５４は、第２の基部１２から立ち上がる立上部１５４Ａと、立上部１５４Ａから突出する突出部１５４Ｂとを含む。突出部１５４Ｂは、立上部１５４Ａに続いて形成される屈曲部１５４Ｂ１と、屈曲部１５４Ｂ１の先端に形成される返し部１５４Ｂ２とを含む。 On the other hand, the female engaging portion 13B includes hook portions 153 and 154 protruding inward.

The projecting portion 154B includes a bent portion 154B1 formed following the rising portion 154A, and a return portion 154B2 formed at the tip of the bent portion 154B1.
　なお、本明細書において「外向き」および「内向き」は、ジッパーテープ１０の幅方向について定義される。図示された例において、雄型係合部１３Ａについては、単一の立上部１５Ａから離れる向きが「外向き」になる。一方、雌型係合部１３Ｂについては、２つの立上部１５３Ａ，１５４Ａに挟まれた内側空間に向かう向き、つまり立上部１５３Ａ，１５４Ａの一方から他方に向かう向きが「内向き」になる。 In this specification, "outward" and "inward" are defined with respect to the width direction of the zipper tape 10. In the illustrated example, the male engaging portion 13A faces "outward" away from the single raised portion 15A. On the other hand, for the female engagement portion 13B, the direction toward the inner space sandwiched between the two raised portions 153A and 154A, that is, the direction from one of the raised portions 153A and 154A to the other is "inward".
　図示されているように、雄型係合部１３Ａおよび雌型係合部１３Ｂは、雄型係合部１３Ａが雌型係合部１３Ｂの内側に嵌合するように構成されている。雄型係合部１３Ａと雌型係合部１３Ｂとが係合したときには、雄型係合部１３Ａの鉤部１５１と雌型係合部１３Ｂの鉤部１５３とが互いに係合し、また雄型係合部１３Ａの鉤部１５２と雌型係合部１３Ｂの鉤部１５４とが互いに係合する。なお、ここまでの構成は、図２に示す一般的なジッパーテープ９０でも同様である。 As shown, the male engaging portion 13A and the female engaging portion 13B are configured such that the male engaging portion 13A fits inside the female engaging portion 13B. When the male engaging portion 13A and the female engaging portion 13B engage with each other, the hook portion 151 of the male engaging portion 13A and the hook portion 153 of the female engaging portion 13B engage with each other. The hook portion 152 of the mold engaging portion 13A and the hook portion 154 of the female mold engaging portion 13B are engaged with each other. The configuration up to this point is the same for the general zipper tape 90 shown in FIG.
　本実施形態に係るジッパーテープ１０では、以下で説明する構成のうち１つ、２つ以上、またはすべてを採用することによって、雄型係合部１３Ａと雌型係合部１３Ｂとを係合させるために必要とされる力が３０Ｎ／１５ｍｍ以上１００Ｎ／１５ｍｍ以下になっている。以下の説明では、雄型係合部１３Ａと雌型係合部１３Ｂとを係合させるために必要とされる力をジッパーテープ１０の閉止強度ともいう。閉止強度は、ジッパーテープを１５ｍｍ幅にカットし、雄型係合部１３Ａと雌型係合部１３Ｂとが係合していない状態で第１の基部１１と第２の基部１２とを対向させ、第２の基部１２の雌型係合部１３Ｂとは反対側の面を台などに載せて固定した上で、第１の基部１１の雄型係合部１３Ａとは反対側の面に圧縮力を加え、雄型係合部１３Ａと雌型係合部１３Ｂとが係合するまでに加えられた圧縮力の最大値を測定することによって算出することができる。圧縮力は、例えば、株式会社イマダ製のデジタルフォースゲージを用いて測定することができるが、この例には限定されない。 In the zipper tape 10 according to this embodiment, the male engaging portion 13A and the female engaging portion 13B are engaged by adopting one, two or more, or all of the configurations described below. The force required for this is 30 N/15 mm or more and 100 N/15 mm or less. In the following description, the force required to engage the male engaging portion 13A and the female engaging portion 13B is also referred to as closing strength of the zipper tape 10. FIG. Closing strength was determined by cutting a zipper tape into a width of 15 mm and placing the first base 11 and the second base 12 in a state where the male engaging portion 13A and the female engaging portion 13B are not engaged. , After fixing the surface of the second base 12 opposite to the female engagement portion 13B on a stand or the like, compress it to the surface of the first base 11 opposite to the male engagement portion 13A. It can be calculated by applying a force and measuring the maximum value of the compressive force applied until the male engaging portion 13A and the female engaging portion 13B are engaged. The compressive force can be measured using, for example, a digital force gauge manufactured by Imada Co., Ltd., but is not limited to this example.
　図２に示す一般的なジッパーテープ９０の場合、閉止強度は１０Ｎ／１５ｍｍから２０Ｎ／１５ｍｍ程度である。本実施形態に係るジッパーテープ１０の閉止強度は３０Ｎ／１５ｍｍ以上であるため、一般的なジッパーテープ９０に比べて係合部が閉じにくい。つまり、ジッパーテープ１０では、係合部の間に介挿するフィルムのような追加の部材がなくても、係合部が閉じることを防止できる。ジッパーテープ１０の閉止強度は、好ましくは３５Ｎ／１５ｍｍ以上であり、より好ましくは４０Ｎ／１５ｍｍ以上である。ジッパーテープ１０が後述するような改ざん防止用途で使用される場合は、閉止強度は５０Ｎ／１５ｍｍ以上であってもよく、好ましくは６０Ｎ／１５ｍｍ以上である。 In the case of the general zipper tape 90 shown in FIG. 2, the closing strength is about 10N/15mm to 20N/15mm. Since the closure strength of the zipper tape 10 according to the present embodiment is 30 N/15 mm or more, the engagement portion is more difficult to close than the general zipper tape 90 . In other words, the zipper tape 10 can prevent the engaging portions from closing without an additional member such as a film inserted between the engaging portions. The closing strength of the zipper tape 10 is preferably 35 N/15 mm or more, more preferably 40 N/15 mm or more. If the zipper tape 10 is used in a tamper-proof application as described below, the closure strength may be 50 N/15 mm or greater, preferably 60 N/15 mm or greater.
　一方、ジッパーテープ１０でも、閉止強度が１００Ｎ／１５ｍｍ以下であることによって、最終的には係合部を閉じることができる。例えば、ジッパーテープ１０は、後述するように容器本体に取り付けられた後に、第１の基部１１または第２の基部１２のいずれかの側を台などに載せて固定するなどの特定の状況でのみ閉じられるように設計されていてもよい。ジッパーテープ１０の閉止強度は、好ましくは８５Ｎ／１５ｍｍ以下であり、より好ましくは７０Ｎ／１５ｍｍ以下である。ジッパーテープ１０が後述するような改ざん防止用途で使用される場合であって、例えば一度開かれた係合部を閉じる必要がないような場合には、閉止強度に上記のような上限はないが、最初に係合部を閉じるために例えば閉止強度を２００Ｎ／１５ｍｍ以下としてもよい。 On the other hand, the zipper tape 10 also has a closing strength of 100 N/15 mm or less, so that the engagement portion can be finally closed. For example, the zipper tape 10 may be used only in certain situations, such as when either the first base 11 or the second base 12 is placed on a stand or the like and fixed after being attached to the container body as described below. It may be designed to be closed. The closing strength of the zipper tape 10 is preferably 85 N/15 mm or less, more preferably 70 N/15 mm or less. When the zipper tape 10 is used for anti-tampering purposes as described later, for example, when it is not necessary to close the engaging portion that has been opened once, the closing strength does not have the upper limit as described above. For example, the closing strength may be 200 N/15 mm or less in order to close the engaging portion first.
　本実施形態に係るジッパーテープ１０の閉止強度を３０Ｎ／１５ｍｍ以上１００Ｎ／１５ｍｍ以下にするために採用されうる構成について、以下で説明する。図示された例では以下の構成（１）～（５）がすべて採用されているが、本発明の実施形態はこのような例には限定されない。既に述べたように、構成（１）～（５）のうち１つだけが採用されてもよいし、複数が採用されてもよいし、すべてが採用されてもよい。 A configuration that can be employed to set the closing strength of the zipper tape 10 according to the present embodiment to 30 N/15 mm or more and 100 N/15 mm or less will be described below. Although the illustrated example employs all of the following configurations (1) to (5), the embodiments of the present invention are not limited to such examples.

　上述したようなジッパーテープ１０は、ポリオレフィン系樹脂、具体的には例えばポリプロピレンを主成分とする樹脂組成物で形成される。この樹脂組成物は、低密度ポリエチレン（ＬＤＰＥ）、または直鎖状低密度ポリエチレン（ＬＬＤＰＥ）を含んでもよい。ＬＤＰＥまたはＬＬＤＰＥの少なくとも一部は、バイオポリエチレンであってもよい。第１の樹脂組成物の主成分であるポリオレフィン系樹脂は、化石燃料由来の樹脂には限られず、環境に配慮したバイオプラスチック（バイオマス由来のバイオポリプロピレンやバイオポリエチレンなどのポリオレフィン系樹脂）であってもよいし、化石燃料由来の樹脂とバイオプラスチックの混合物であってもよい。第１の樹脂組成物には、必要に応じて、公知の添加剤、例えば安定剤、酸化防止剤、滑剤、帯電防止剤、または着色剤などが添加されてもよい。ジッパーテープ１０は、必ずしも全体が同じ樹脂組成物で形成されなくてもよく、例えば、第１の基部１１および第２の基部１２を形成する樹脂組成物と、雄型係合部１３Ａおよび雌型係合部１３Ｂを形成する樹脂組成物とが異なっていてもよい。 The zipper tape 10 as described above is made of a polyolefin resin, specifically, a resin composition containing, for example, polypropylene as a main component. The resin composition may comprise low density polyethylene (LDPE) or linear low density polyethylene (LLDPE). At least a portion of the LDPE or LLDPE may be bio-polyethylene. The polyolefin resin, which is the main component of the first resin composition, is not limited to a fossil fuel-derived resin, but is an environmentally friendly bioplastic (polyolefin resin such as biomass-derived bio-polypropylene or bio-polyethylene). or a mixture of fossil fuel-derived resins and bioplastics. Known additives such as stabilizers, antioxidants, lubricants, antistatic agents, or colorants may be added to the first resin composition, if necessary. The zipper tape 10 does not necessarily have to be entirely made of the same resin composition. The resin composition forming the engaging portion 13B may be different.
　雄型係合部１３Ａおよび雌型係合部１３Ｂを形成する樹脂組成物の成分によって、雄型係合部１３Ａおよび雌型係合部１３Ｂの剛性は変化し、それによってジッパーテープ１０の閉止強度も変化する。本実施形態では、上記の構成（１）～（５）を、例えば雄型係合部１３Ａおよび雌型係合部１３Ｂを形成する樹脂組成物の成分に応じて選択的に採用することによって、ジッパーテープ１０の閉止強度を３０Ｎ／１５ｍｍ以上１００Ｎ／１５ｍｍ以下にしている。 The rigidity of the male engaging portion 13A and the female engaging portion 13B varies depending on the components of the resin composition forming the male engaging portion 13A and the female engaging portion 13B, thereby increasing the closing strength of the zipper tape 10. also change. In this embodiment, by selectively adopting the above configurations (1) to (5) according to the components of the resin composition forming the male engaging portion 13A and the female engaging portion 13B, The closing strength of the zipper tape 10 is set to 30 N/15 mm or more and 100 N/15 mm or less.
　図３は、図１に示したジッパーテープを含むジッパーテープ付き容器の平面図である。図示された例において、ジッパーテープ付き容器１００は、収納空間ＳＰに面する第１面１１１Ａおよび第２面１１１Ｂを有するフィルム１１０によって形成される袋状の容器本体と、ジッパーテープ１０とを含む。ジッパーテープ１０は、第１の基部１１が第１面１１１Ａに、第２の基部１２が第２面１１１Ｂに、それぞれ接合されることによって容器本体に取り付けられる。 FIG. 3 is a plan view of a container with a zipper tape including the zipper tape shown in FIG. In the illustrated example, the zipper tape-equipped container 100 includes a bag-like container body formed of a film 110 having a first surface 111A and a second surface 111B facing the storage space SP, and the zipper tape 10 . The zipper tape 10 is attached to the container body by bonding the first base portion 11 to the first surface 111A and the second base portion 12 to the second surface 111B, respectively.
　なお、図示された例では、２枚のフィルム１１０がボトムシール部１１２およびサイドシール部１１３で互いに接合されることによって袋状の容器本体を形成しているが、他の例では１枚のフィルム１１０がサイドシール部１１３に対応する部分で折り返されることによって袋状の容器本体を形成してもよい。また、ボトムシール部１１２またはサイドシール部１１３に対応する部分でフィルム１１０が内側に折り込まれた部分、いわゆるガセットが形成されてもよい。この場合、ガセットは、フィルム１１０によって形成されてもよいし、フィルム１１０に接合された別のフィルムによって形成されてもよい。ジッパーテープ付き容器１００は、底部にガセットが形成されることによって立てて置くことが可能なスタンディングパウチであってもよい。また、図示された例ではジッパーテープ１０に対して収納空間ＳＰとは反対側にではフィルム１１０の第１面１１１Ａと第２面１１１Ｂとの間が接合されずに開口１０１が形成されているが、この部分でも第１面１１１Ａと第２面１１１Ｂとの間が接合されてトップシール部が形成され、トップシール部とジッパーテープ１０との間を切断することによって事後的に開口が形成されてもよい。 In the illustrated example, two sheets of film 110 are joined together at the bottom seal portion 112 and the side seal portion 113 to form the bag-like container body, but in other examples, one sheet of film is used. A bag-shaped container body may be formed by folding back the portion 110 corresponding to the side seal portion 113 . Also, a portion corresponding to the bottom seal portion 112 or the side seal portion 113 may be formed with the film 110 folded inward, that is, a so-called gusset. In this case, the gusset may be formed by film 110 or by another film joined to film 110 . The zipper tape-equipped container 100 may be a standing pouch that can be placed upright by forming a gusset on the bottom. In the illustrated example, an opening 101 is formed on the opposite side of the zipper tape 10 from the storage space SP without connecting the first surface 111A and the second surface 111B of the film 110. Also in this portion, the first surface 111A and the second surface 111B are joined to form a top seal portion, and an opening is formed afterward by cutting between the top seal portion and the zipper tape 10. good too.
　上記の例において、フィルム１１０は、例えば単層または多層の熱可塑性樹脂で形成される。より具体的には、フィルム１１０は、例えばポリプロピレンまたは高密度ポリエチレン（ＨＤＰＥ）、直鎖状低密度ポリエチレン（ＬＬＤＰＥ）、で形成される。ポリプロピレンは、例えばホモポリプロピレン（ＨＰＰ）、ランダムポリプロピレン（ＲＰＰ）、またはブロックポリプロピレン（ＢＰＰ）である。フィルム１１０が多層である場合、表基材に二軸延伸ポリプロピレン（ＯＰＰ）、二軸延伸ポリエチレンテレフタレート（ＯＰＥＴ）、または二軸延伸ナイロン（ＯＮｙ）を用いてもよい。これらは、化石燃料由来の樹脂には限られず、環境に配慮したバイオプラスチック（バイオマス由来のバイオポリプロピレンやバイオポリエチレンなどのポリオレフィン系樹脂）であってもよいし、化石燃料由来の樹脂とバイオプラスチックの混合物であってもよい。フィルム１１０は、アルミニウム蒸着やアルミニウム箔の積層などによって形成された無機材料層を含んでもよい。 In the above example, the film 110 is formed of, for example, a single layer or multiple layers of thermoplastic resin. More specifically, film 110 is formed of, for example, polypropylene or high density polyethylene (HDPE), linear low density polyethylene (LLDPE). Polypropylene is for example homopolypropylene (HPP), random polypropylene (RPP) or block polypropylene (BPP). When the film 110 is multi-layered, biaxially oriented polypropylene (OPP), biaxially oriented polyethylene terephthalate (OPET), or biaxially oriented nylon (ONy) may be used for the face substrate. These are not limited to fossil fuel-derived resins, but may be environmentally friendly bioplastics (polyolefin resins such as biomass-derived bio-polypropylene or bio-polyethylene). It may be a mixture. The film 110 may include an inorganic material layer formed by vapor deposition of aluminum, lamination of aluminum foil, or the like.
　上記のようなジッパーテープ付き容器１００では、ジッパーテープ１０の閉止強度が３０Ｎ／１５ｍｍ以上１００Ｎ／１５ｍｍ以下であり、一般的なジッパーテープに比べて係合部が閉じにくい。従って、例えばジッパーテープ１０の係合部が開いた状態でジッパーテープ付き容器１００を搬送する場合に、係合部の間に介挿するフィルムのような追加の部材がなくても係合部が閉じるのを防止し、その後に開放されたジッパーテープ１０の間から収納空間ＳＰに内容物を封入して、係合部を閉じることができる。 In the container 100 with a zipper tape as described above, the closure strength of the zipper tape 10 is 30 N/15 mm or more and 100 N/15 mm or less, and the engaging portion is more difficult to close than a general zipper tape. Therefore, for example, when the container 100 with the zipper tape 10 is conveyed with the engaging portions of the zipper tape 10 open, the engaging portions can be maintained even without an additional member such as a film inserted between the engaging portions. After preventing the closure, the contents can be enclosed in the storage space SP from between the opened zipper tapes 10, and the engagement part can be closed.
　あるいは、上記のようなジッパーテープ付き容器１００を用いた改ざん防止方法が実施されてもよい。ジッパーテープ１０では閉止強度が３０Ｎ／１５ｍｍ以上に設定されるため、通常想定される力、例えば人間が第１面１１１Ａおよび第２面１１１Ｂの外側からジッパーテープ１０を挟み込んで閉じようとした場合に加えられる力よりも大きい閉止強度を設定することができる。この場合、ジッパーテープ１０の係合部は、一度開かれると、簡単には閉じることができない。従って、例えば何者かによって内容物が改ざんされた場合にはジッパーテープ１０の係合部が開いたままになるため、改ざんを検知することができる。 Alternatively, a tampering prevention method using the container 100 with a zipper tape as described above may be implemented. Since the closure strength of the zipper tape 10 is set to 30 N/15 mm or more, the normally assumed force, for example, when a person tries to close the zipper tape 10 by pinching the zipper tape 10 from the outside of the first surface 111A and the second surface 111B A closure strength greater than the applied force can be set. In this case, once the engaging portion of the zipper tape 10 is opened, it cannot be closed easily. Therefore, if the contents are tampered with by someone, the engaging portion of the zipper tape 10 remains open, so the tampering can be detected.
　本発明の実施例および比較例として、以下の表１に示すような形状の係合部が形成されたジッパーテープについて、閉止強度、すなわち雄型係合部と雌型係合部とを係合させるために必要とされる力を測定した。本実施例において、閉止強度は、ジッパーテープを１５ｍｍ幅にカットし、係合部が係合していない状態で基部を対向させ、雌側の基部の係合部とは反対側の面を台に載せて固定した上で、雄側の基部の係合部とは反対側の面に圧縮力を加え、係合部が係合するまでに加えられた圧縮力の最大値を、株式会社イマダ製のデジタルフォースゲージ（機種名：ＺＴＳ－２００Ｎ）を用いて測定することによって算出した。 As examples and comparative examples of the present invention, zipper tapes formed with engaging portions having shapes as shown in Table 1 below were tested for closing strength, that is, engagement between the male engaging portion and the female engaging portion. We measured the force required to In this embodiment, the closing strength was measured by cutting the zipper tape into a width of 15 mm, facing the base with the engaging portion not engaged, and placing the female base on the side opposite to the engaging portion. After placing it on and fixing it, a compressive force is applied to the surface opposite to the engaging part of the male base, and the maximum value of the compressive force applied until the engaging part is engaged is measured by Imada Co., Ltd. It was calculated by measuring using a digital force gauge (model name: ZTS-200N) manufactured by
