Description

明 細 書 開封テープ付密封袋 技術分野  Description Sealing bag with opening tape Technical field
本発明は、 開封テープ付密封袋に関する。 詳しくは、 食品、 医薬品等を包装す る包装袋の開口部側に設けられる開封テ一プ付密封袋に関する。  The present invention relates to a sealed bag with an opening tape. More specifically, the present invention relates to a sealed bag with an opening tape provided on the opening side of a packaging bag for packaging foods, pharmaceuticals, and the like.
背景技術 Background art
従来、 袋の開封部に雄型咬合具と雌型咬合具より成る咬合具 （嵌合具） を設け ることにより、 開閉自在とした袋 （チャック袋） が食品、 医薬品、 雑貨等の多く の分野で使用されている。 このような咬合具付袋でも、 販売時点までは完全密閉 されていることが望ましく、 咬合部分に沿って端部を完全に密封することが一般 的である。 密封シールされる咬合具付袋では、 使用時に咬合具と開口側シール部 分との間を切断し、その後は咬合具部分で開封、再密封することが一般的である。 密封シールされる袋の開封には、利用者が従来の鉄を使って切断する方法の他、 切断すべき部分の側端から手で引き裂く方法が採られる。 手で引き裂く操作を容 易にするために、 袋の側端にノツチを形成することもなされている。  Conventionally, a bag (chuck bag) that can be opened and closed freely is provided by providing a jaw tool (fitting tool) consisting of a male jaw tool and a female jaw tool at the opening of the bag. Used in the field. It is desirable that even such a bag with an articulation tool be completely sealed until the point of sale, and it is common to completely seal the end along the occlusion part. In a bag with a jaw that is hermetically sealed, it is common to cut the space between the jaw and the opening-side seal portion at the time of use, and then open and reseal at the jaw portion. In order to open the hermetically sealed bag, the user can use a conventional method of cutting with iron or a method of tearing by hand from the side edge of the part to be cut. Notches have also been formed on the side edges of the bags to facilitate the tearing operation by hand.
しかし、 鋏の使用は面倒であり、 且つ鋏がないと切れないという欠点がある。 また、 ノツチから引き裂く切断の仕方によれば直線状にきれいに切れないという 欠点がある。 そこで、 近年では、 鋏等の道具を使うことなく手で直線状に引き裂 くための手段として、 例えば次のような手段が提案されている。  However, the use of scissors is troublesome, and the scissors cannot be cut without scissors. In addition, there is a disadvantage that it cannot be cut straight in a straight line according to the cutting method of tearing from the notch. Therefore, in recent years, the following means have been proposed as means for tearing in a straight line by hand without using tools such as scissors.
手段 1 ；引き裂き線として開口部側にミシン目を形成する。  Means 1: A perforation is formed on the opening side as a tear line.
手段 2 ；袋体を構成するラミネートフィルムの内面側フィルムを肉厚に形成す ると共に、 この内面側フィルムに咬合具を形成し、 且つこの内面側フィルムの咬 合具よりも端縁側に切り込み線を形成する （実公昭 5 2— 1 8 2 5 4号公報参 照） 。  Means 2: The inner side film of the laminated film constituting the bag body is formed to be thick, and a jig is formed on the inner side film, and a cutting line is formed on the inner side of the inner side film on the edge side of the jaw. (See Japanese Utility Model Publication No. 52-182254).
手段 3；特殊な形状の切断線を形成する（実開昭 6 2 - 1 3 8 3 8号公報参照）。 し力 しながら、 前述した各手段には次のような問題がある。 Means 3; A cutting line having a special shape is formed (see Japanese Utility Model Application Laid-Open No. 62-13838). However, each of the above-mentioned means has the following problems.
手段 1では、 ミシン目のため密封性が低く、 輸送時等において何らかの原因で 開封してしまうという問題がある。  Means 1 has a problem that the sealing property is low due to perforations and the package is opened for some reason during transportation.
手段 2では、 切り込み線の形成された内面側フィルム単体のままではきれいに 裂けても、これを基材フィルムに熱溶着した場合、熱の影響で切り込み線が埋まつ て引き裂きにくくなるという問題がある。  Means 2 has a problem that even if the inner film alone with the score line is torn cleanly as it is, if it is thermally welded to the base film, the score line is buried due to the heat and it is difficult to tear. .
手段 3では、 密封性が不充分であり、 且つ特殊な切断線を形成するための工程 が複雑になるという問題がある。  Means 3 has a problem that the sealing performance is insufficient and the process for forming a special cutting line is complicated.
発明の開示 Disclosure of the invention
本発明の主な目的は、 使用前の密封性が確実であり、 且つ、 手による切断開封 を容易に行うことができる開封テープ付密封袋を提供することにある。  A main object of the present invention is to provide a sealed bag with an opening tape which can ensure the sealing property before use and can be easily cut and opened by hand.
本発明は、 包装袋の開口部側に開封テープが設けられる開封テープ付密封袋で あって、 前記包装袋の内側の一方の面に、 前記開口部に平行に貼着される帯状の 開封テープを備え、 前記包装袋の前記開封テープの端部側には、 前記開封テープ の貼着面の反対側の面に切欠部が形成されていることを特徴とする。  The present invention is a sealed bag with an opening tape provided with an opening tape on the opening side of the packaging bag, and a strip-shaped opening tape adhered to one inner surface of the packaging bag in parallel with the opening. A notch is formed on the side of the packaging bag opposite to the surface to which the opening tape is attached, on the end side of the opening tape.
ここで、 開封テープの貼着は、 接着剤を用いた接着やヒートシール等による熱 溶着により行われる。 本発明のテープとしては幅広いものに限らず、 幅の狭いも のであってもよく、引き裂きガイド効果が得られれば紐状のものであってもよい。 テープとしては、ある程度幅が狭いほうが引き裂きガイド効果が高くなる。但し、 幅が広ければ、 薄くても引っ張り強度が得られる。 幅を狭くする場合、 厚みを増 す等すれば強度が確保でき、 断面が楕円形ないし円形のいわゆる紐状にしてもよ レ、。  Here, the sticking of the opening tape is performed by adhesion using an adhesive or heat welding by heat sealing or the like. The tape of the present invention is not limited to a wide tape, but may be a narrow tape, and may be a cord-like tape as long as a tear guide effect is obtained. As a tape, the smaller the width is, the higher the tear guide effect becomes. However, if the width is wide, tensile strength can be obtained even if it is thin. When the width is reduced, the strength can be secured by increasing the thickness, etc., and the cross section may be an elliptical or circular so-called string shape.
このような本発明によれば、 包装袋の内側の一方の面に、 前記開口部に平行に 貼着される帯状の開封テープを備えて構成されることにより、 ミシン目等を設け る構造でないため、 外部との隙間が生じないので、 包装袋の開封前の密封性を確 実にすることができる。 また、 包装袋の前記開封テープの端部側には、 開封テープの貼着面の反対側の 面に切欠部が形成されていることにより、 切欠部がある部分は、 開封テープと包 装袋の一方の面だけになるから、 切込部で開封テープ端部が露出するので、 容易 に、 切込部を起こすことができる。 本発明の開封テープ付密封袋では、 前記包装袋および Zまたは前記開封テープ には、 前記開封テープの端部から切り込まれて終端部が前記開封テープの内側に 位置する一対の切込部が形成されていることが望ましい。 According to the present invention as described above, since one side of the inner side of the packaging bag is provided with the band-shaped opening tape attached in parallel with the opening, the perforation is not provided. Therefore, there is no gap with the outside, so that the sealing performance before opening the packaging bag can be ensured. In addition, a notch is formed on the surface of the packaging bag opposite to the surface to which the opening tape is attached, on the end side of the opening tape, so that the portion with the notch is provided by the opening tape and the packaging bag. Since only one surface of the tape is used, the end of the opening tape is exposed at the cut portion, so that the cut portion can be easily raised. In the sealed bag with an opening tape according to the present invention, the packaging bag and the Z or the opening tape each have a pair of cut portions cut from an end of the opening tape and having an end portion located inside the opening tape. Preferably, it is formed.
このような本発明によれば、 前記包装袋および Zまたは前記開封テープの前記 開封テープ端部側に一対の切込部が形成されていることにより、 この切込部に挟 まれた部分がタブ状となり、 包装袋の開封時にこのタブ状の部分をそのままつま み部分として把持することができるので、 手による切断開封を容易に行うことが できる。 本発明の開封テープ付密封袋では、 前記切込部は、 前記開封テープに対して傾 斜配置され、 各々の切込みの基端部側が前記開封テープの外側に配置されている ことが望ましい。  According to the present invention, since a pair of cut portions are formed on the packaging bag and the Z or the opening tape on the end side of the opening tape, the portion sandwiched by the cut portions is a tab. When the packaging bag is opened, the tab-shaped portion can be grasped as a knob as it is, so that the cutting and opening by hand can be easily performed. In the sealed bag with an opening tape according to the present invention, it is preferable that the cut portion is inclined with respect to the opening tape, and a base end side of each cut is arranged outside the opening tape.
このような本発明によれば、 切込部が傾斜していることにより、 開封テープの 貼着の位置が多少ずれていても、 包装袋の一方の面と開封テープに確実に切込部 を形成することができる。 特に、 一対の切込部は袋の奥側 （切断が進む方向） に 向かうにしたがって、互いに近接する状態となり、切断線を所定の位置（開封テー プの中心線など） に誘導することができ、 手による切断であっても所定の切断状 態を確実に確保することができる。 本発明の開封テープ付密封袋では、 前記開封テープは、 長尺方向に一軸延伸加 ェされていることが好ましい。  According to the present invention as described above, since the notch is inclined, even if the position of the sticking of the opening tape is slightly displaced, the notch is securely inserted into one surface of the packaging bag and the opening tape. Can be formed. In particular, the pair of cuts become closer to each other as they move toward the back of the bag (the direction in which cutting proceeds), and can guide the cutting line to a predetermined position (such as the centerline of the opening tape). However, even when cutting by hand, a predetermined cutting state can be reliably ensured. In the sealed bag with the opening tape of the present invention, the opening tape is preferably uniaxially stretched in the longitudinal direction.
ここで、 延伸とは、 繊維状あるいはフィルム状の高分子材料を物理的に引き伸 ばすことをいう。 これにより、 高分子材料の強度や弾性率の向上をはかることが でき、 結晶性高分子をガラス転移温度以上、 融点以下の温度で延伸すると、 非晶 部分の分子が延伸方向に引き伸ばされ、 結晶化度が増すとともに、 分子が延伸方 向に配向する。 その結果、 延伸方向の引張強度や引張弾性率が大きくなる。 一軸 延伸とは、 ある一定方向に引き伸ばすことをいい、 例えば、 フィルムを一軸延伸 すると、延伸方向の強度が垂直方向に比べて増加し， 異方性材料となり、 さらに、 引き裂いた場合には、 延伸方向に引き裂かれる指向性が強くなる。 Here, stretching means physically stretching a fibrous or film-like polymer material. As a result, the strength and elastic modulus of the polymer material can be improved. When the crystalline polymer is stretched at a temperature equal to or higher than the glass transition temperature and equal to or lower than the melting point, the molecules in the amorphous portion are stretched in the stretching direction, thereby increasing the crystallinity and orienting the molecules in the stretching direction. As a result, the tensile strength and tensile modulus in the stretching direction increase. Uniaxial stretching refers to stretching in a certain direction. For example, when a film is uniaxially stretched, the strength in the stretching direction increases as compared with the vertical direction, and the film becomes anisotropic material. The directivity torn in the direction becomes stronger.
これにより、 延伸倍率は、 5倍以上、 好ましくは 8〜1 2倍がよい。 開封テー プは、 長尺方向に一軸延伸加工されていることにより、 引き裂きの指向性が強く なるので、 開封テープの長尺方向に沿って直線的に開封することができる。 本発明の開封テープ付密封袋では、 前記開封テープは、 ポリオレフイン系樹脂 製であることが好ましく、 そのなかでも、 ポリオレフイン系樹脂は、 ポリエチレ ン系樹脂またはポリプロピレン系樹脂が好ましい。  As a result, the stretching ratio is 5 times or more, preferably 8 to 12 times. Since the opening tape is uniaxially stretched in the longitudinal direction, the directivity of tearing is enhanced, so that the opening tape can be opened linearly along the longitudinal direction of the opening tape. In the sealed bag with the opening tape of the present invention, the opening tape is preferably made of a polyolefin resin, and among them, the polyolefin resin is preferably a polyethylene resin or a polypropylene resin.
ここで、 ポリオレフイン系樹脂としては、 ポリエチレン、 ポリプロピレン、 ポ リブテン等がある。  Here, examples of the polyolefin resin include polyethylene, polypropylene, and polybutene.
ポリエチレン系樹脂としては、 直鎖状低密度ポリエチレン （L L D P E ) 、 高 密度ポリエチレン （H D P E ) 、 低密度ポリエチレン （L D P E ) 等が挙げられ る。  Examples of the polyethylene-based resin include linear low-density polyethylene (LLDP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), and the like.
ポリプロピレン系樹脂としては、 ポリプロピレンとしては、 ホモポリプロピレ ン、 ランダムポリプロピレン、 ブロックポリプロピレン等が挙げられる。  Examples of the polypropylene resin include homopolypropylene, random polypropylene, and block polypropylene.
これによれば、 開封テープは、 ポリオレフイン系樹脂製であることにより、 ポ リオレフイン系樹脂は熱可塑性を備えるので、成形、延伸等の加工が容易である。 また、 ポリエチレン系樹脂は、 防湿性， 耐水性， 耐寒性， 耐薬品性に優れ柔軟 であり、 液状の被包装体を包装する際に好適である。  According to this, since the opening tape is made of a polyolefin resin, and the polyolefin resin has thermoplasticity, processing such as molding and stretching is easy. In addition, polyethylene resins are excellent in moisture resistance, water resistance, cold resistance, and chemical resistance and are flexible, and are suitable for packaging liquid packaging objects.
さらに、 ポリプロピレン系樹脂は、 比重が小さくので、 包装袋自体の重さを軽 くすることができる。 本発明の開封テープ付密封袋では、 雌雄一対の部材の部材からなる咬合具が、 袋内面側にそれぞれ貼着されていることが好ましい。 Further, since the polypropylene resin has a small specific gravity, the weight of the packaging bag itself can be reduced. In the sealed bag with the opening tape of the present invention, a jaw comprising a pair of male and female members, It is preferable that they are respectively adhered to the bag inner surface side.
これによれば、 雌雄一対の部材の部材からなる咬合具が、 袋内面側にそれぞれ 貼着されていることにより、 咬合具は、 再開閉可能であるので、 袋の密封性を保 持することができる。 図面の簡単な説明  According to this, since the occlusal tool composed of a pair of male and female members is adhered to the inner surface side of the bag, the occlusal tool can be opened and closed again, so that the bag can be kept hermetically sealed. Can be. BRIEF DESCRIPTION OF THE FIGURES
