Abstract

A female-side band-shaped base section (22A) with which a female-side hook section (22C) is interconnected is provided with a thin-walled section (22A1) located on the containing space (14) side, in the width direction, of the base end of the female-side hook section (22C). When inner pressure increases, the pressure acts on the base end of a second engagement section (24) and the thin-walled section (22A1) breaks off. The female-side band-shaped base section (22A) is attached only on the opening section (12) side thereof in the width direction and becomes the so-called one-side-detached state which provides excellent sealing characteristics and excellent easy-to-open characteristics.

　本実施形態では、ジッパーテープ付袋体として、食品、薬品、医療品、文具、雑貨などの各種物品を包装する袋体を例示するが、この限りではない。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the present embodiment, as a bag body with a zipper tape, a bag body that wraps various articles such as foods, medicines, medical products, stationery, and miscellaneous goods is exemplified, but the present invention is not limited thereto.
［ジッパーテープ付袋体の構造］
　図１に示すように、ジッパーテープ付袋体１は、袋本体１０と、袋本体１０の内面に接合、例えばヒートシールされたジッパーテープ２０と、を備えている。 [Structure of bag with zipper tape]
As shown in FIG. 1, the bag body 1 with a zipper tape includes a bag body 10 and a zipper tape 20 that is bonded, for example, heat-sealed, to the inner surface of the bag body 10.
　（袋本体の構成）
　袋本体１０は、フィルムである基材フィルム１１が折り返されて重ね合わされ、重なり合う両縁に図示しない一対のサイドシール部とトップシール部が形成される。
　そして、袋本体１０は、折り返されて重なり合う縁が、ジッパーテープ２０を取り付ける開口部１２の縁となり、内部に被包装物を収納する収納空間１４を区画形成している。なお、開口部１２の縁は、被包装物が収納された後、トップシール部が形成されて封止される。 (Bag body configuration)
The bag body 10 is folded and overlapped with a base film 11 that is a film, and a pair of side seal portions and a top seal portion (not shown) are formed on both overlapping edges.
And the bag body 10 is folded and overlapped, the edge becomes the edge of the opening 12 to which the zipper tape 20 is attached, and the storage space 14 for storing the packaged object is defined in the inside. The edge of the opening 12 is sealed by forming a top seal portion after the article to be packaged is stored.
　基材フィルム１１としては、例えば、（直鎖状）低密度ポリエチレン（Linear Low Density Polyethylene：ＬＬＤＰＥ）、ポリプロピレン（Polypropylene：ＰＰ）などの熱可塑性樹脂にて形成された単層または多層のフィルムを利用できる。多層のフィルムとしては、表基材に、二軸延伸したポリプロピレン（Oriented Polypropylene：ＯＰＰ）、二軸延伸ポリエチレンテレフタレート（ＯＰＥＴ）、二軸延伸ナイロン（ＯＮｙ）、キャストポリプロピレン（Cast Polypropylene：ＣＰＰ）などを用いることができる。なお、多層フィルムとして、いわゆるガスバリアーや遮光などの目的で、アルミニウム蒸着やアルミニウム箔の積層など、無機系の層を備えた構成としてもよい。
　また、基材フィルム１１は、包装袋用材料であれば特に限定されないが、例えば厚み寸法が１０μｍ以上２００μｍ以下であることが好ましい。厚み寸法が１０μｍ未満であると、シール強度、袋強度が弱くなる場合がある。一方、厚み寸法が２００μｍを超えると、袋の開封がしにくくなる場合がある。 As the base film 11, for example, a single-layer or multi-layer film formed of a thermoplastic resin such as (linear) low density polyethylene (LLDPE) or polypropylene (polypropylene: PP) is used. it can. Multi-layer films include biaxially oriented polypropylene (Oriented Polypropylene: OPP), biaxially oriented polyethylene terephthalate (OPET), biaxially oriented nylon (ONy), cast polypropylene (Cast Polypropylene: CPP), etc. Can be used. The multilayer film may have a configuration including an inorganic layer such as aluminum vapor deposition or lamination of aluminum foil for the purpose of so-called gas barrier or light shielding.
In addition, the base film 11 is not particularly limited as long as it is a packaging bag material, but for example, the thickness dimension is preferably 10 μm or more and 200 μm or less. If the thickness dimension is less than 10 μm, the seal strength and bag strength may be weakened. On the other hand, when the thickness dimension exceeds 200 μm, it may be difficult to open the bag.

　（ジッパーテープ付袋体の製造方法）
　次に、上記製造装置３を用いたジッパーテープ付袋体１の製造方法について図面を参照して説明する。 (Manufacturing method of bag with zipper tape)
Next, the manufacturing method of the bag body 1 with a zipper tape using the said manufacturing apparatus 3 is demonstrated with reference to drawings.
　ジッパーテープ付袋体１の製造方法は、例えば図３に示す三方製袋する製造装置３を用いて製造され、ジッパーテープ２０を繰り出すテープ操出工程と、ジッパーテープ２０を基材フィルム１１に接合させるテープ取付工程と、基材フィルム１１からジッパーテープ付袋体１を形成させる製袋工程と、などを実施する。 The manufacturing method of the bag body 1 with a zipper tape is manufactured using, for example, the manufacturing apparatus 3 for making a three-side bag shown in FIG. 3, and a tape feeding process for feeding out the zipper tape 20, and joining the zipper tape 20 to the base film 11. A tape attaching step to be performed, a bag making step for forming the bag body 1 with a zipper tape from the base film 11, and the like are performed.
　テープ操出工程で、テープ巻取ロール３１１からジッパーテープ２０を引き出し、ジッパーテープ接合装置３２へ繰り出し、テープ取付工程を実施させる。
　テープ取付工程では、ジッパーテープ接合装置３２により、位置決めガイド部でジッパーテープ２０と基材フィルム１１とを位置決めする。そして、ジッパーテープ接合装置３２は、シールバー３２１によりジッパーテープ２０の雄部材２１および雌部材２２を基材フィルム１１にそれぞれヒートシールする。
　このジッパーテープ２０のシールの際、雄側帯状基部２１Ａおよび雌側帯状基部２２Ａは、それぞれ幅方向の両端側がシールされる。 In the tape feeding process, the zipper tape 20 is pulled out from the tape take-up roll 311 and fed out to the zipper tape joining apparatus 32 to perform the tape attaching process.
In the tape attachment step, the zipper tape bonding device 32 positions the zipper tape 20 and the base film 11 at the positioning guide portion. Then, the zipper tape joining device 32 heat seals the male member 21 and the female member 22 of the zipper tape 20 to the base film 11 using the seal bar 321.
When the zipper tape 20 is sealed, the male side belt-like base portion 21A and the female side belt-like base portion 22A are sealed at both ends in the width direction.
　この後、製袋工程でジッパーテープ付袋体１を製袋する。製袋に際して、まずボトムシールバー３３１によりボトムシール部１３を形成する。この後、潰しバー３３２により、ジッパーテープ２０を所定間隔で潰す。続いて、潰しバー３３２でジッパーテープ２０を潰した位置でサイドシールバー３３３により、基材フィルム１１をシールしてサイドシール部を形成する。第一切断部３３４および第二切断部３３５によりそれぞれ切断し、ボトムシール部１３とサイドシール部との三方がシールされたジッパーテープ付袋体１を切り出す。

When making a bag, first, the bottom seal portion 13 is formed by the bottom seal bar 331. Thereafter, the zipper tape 20 is crushed at a predetermined interval by a crushing bar 332. Subsequently, the base film 11 is sealed by the side seal bar 333 at the position where the zipper tape 20 is crushed by the crushing bar 332 to form a side seal portion. The bag body 1 with a zipper tape which cut | disconnected by the 1st cutting part 334 and the 2nd cutting part 335, respectively, and was sealed by the three sides of the bottom seal part 13 and the side seal part is cut out.
And the to-be-packaged goods P are thrown into the obtained bag body 1 with a zipper tape from the opening part 12 side by the filling apparatus which is not shown in figure, and it seals by engagement of the zipper tape 20. FIG.
［内圧作用時および開封時の動作］
　次に、上記ジッパーテープ付袋体１の内圧作用時および開封時の動作を、図面を参照して説明する。
　図４は、ジッパーテープ付袋体１に内圧を加えた際の雄部および雌部の係合状態を説明する断面図である。図５は、内圧が加わった際のジッパーテープ付袋体１の雄部および雌部の係合状態を説明する断面図である。図６は、ジッパーテープ付袋体１を開封する際の雄部および雌部の係合解除を説明する断面図である。 [Operation during internal pressure action and opening]
Next, the operation | movement at the time of the internal pressure effect | action of the said bag body 1 with a zipper tape and opening is demonstrated with reference to drawings.
FIG. 4 is a cross-sectional view illustrating the engaged state of the male part and the female part when internal pressure is applied to the bag body 1 with a zipper tape. FIG. 5 is a cross-sectional view illustrating the engaged state of the male part and the female part of the bag body 1 with a zipper tape when an internal pressure is applied. FIG. 6 is a cross-sectional view illustrating the disengagement of the male part and the female part when opening the bag body 1 with a zipper tape.
　（内圧作用時）
　被包装物を封止した状態で、ジッパーテープ付袋体１に外力が作用したり加熱などにて内圧が高くなると、内圧は、第二係合部２４に作用する。このことにより、図４および図５に示すように、第二係合部２４の雌側鉤部２２Ｃの基端の弱い部分である薄肉部２２Ａ１が切断される。なお、切断された雌側帯状基部２２Ａの一端側となる部分が帯状部材２２Ａ３として袋本体１０に接合したままの状態となる。この薄肉部２２Ａ１が切断した状態では、雌部材２２は、雌側帯状基部２２Ａの幅方向における開口部１２側のみが袋本体１０に取り付けられた、いわゆる片側外し状態となる。
　この片側外し状態で、内圧が作用すると、図５中の矢印方向に雄側帯状基部２１Ａおよび雌側帯状基部２２Ａが移動する状態となる。この状態では、雄部２１Ｂの雄側鉤領域２１Ｂ３と雌部２２Ｂの雌側爪領域２２Ｂ３と、および、雄側鉤部２１Ｃの雄側鉤状領域２１Ｃ１と雌側鉤部２２Ｃの雌側鉤状領域２２Ｃ１とが、互いに引っ張り合うように噛合する。このことにより、第一係合部２３および第二係合部２４の係合がより強くなり、開口部１２は開封されない。
　なお、高まった内圧の一部は、袋本体１０と雌側帯状基部２２Ａとの間に作用し、雄部材２１および雌部材２２の係合部分には残りの内圧が作用することとなり、内圧の作用により直接係合が解除されにくく、漏れを防止できる。 (Internal pressure action)
When an external force is applied to the zipper tape-attached bag body 1 or the internal pressure is increased by heating or the like in a state where the article to be packaged is sealed, the internal pressure acts on the second engaging portion 24. As a result, as shown in FIGS. 4 and 5, the thin portion 22 </ b> A <b> 1 that is a weak portion of the proximal end of the female side flange 22 </ b> C of the second engagement portion 24 is cut. In addition, the part used as the one end side of the cut | disconnected female side strip | belt-shaped base 22A will be in the state still joined to the bag main body 10 as strip | belt-shaped member 22A3. In a state where the thin portion 22A1 is cut, the female member 22 is in a so-called one-side removed state in which only the opening 12 side in the width direction of the female-side belt-like base portion 22A is attached to the bag body 10.
When the internal pressure is applied in this one-side removed state, the male side belt-like base 21A and the female side belt-like base 22A move in the direction of the arrow in FIG. In this state, the male side collar region 21B3 of the male part 21B and the female side claw area 22B3 of the female part 22B, and the male side collar area 21C1 of the male side collar part 21C and the female side collar shape of the female side collar part 22C. The region 22C1 meshes with each other so as to pull each other. As a result, the engagement between the first engagement portion 23 and the second engagement portion 24 becomes stronger, and the opening 12 is not opened.
A part of the increased internal pressure acts between the bag body 10 and the female band base 22A, and the remaining internal pressure acts on the engaging portions of the male member 21 and the female member 22, and the internal pressure is reduced. Direct engagement is difficult to be released by the action, and leakage can be prevented.
　（開封時）
　一方、開封に際しては、トップシール部を除去して開口部１２を開口させる。そして、図６に示すように、開口部１２の縁を互いに離間する矢印方向に引っ張る。このことにより、雄側帯状基部２１Ａおよび雌側帯状基部２２Ａが湾曲するように屈曲される状態となる。
　このため、雄部２１Ｂの雄側爪領域２１Ｂ２および雌部２２Ｂの雌側爪領域２２Ｂ３が外れる方向に移動され、雄側爪領域２１Ｂ２の先端および雄部２１Ｂの先端が雌部２２Ｂの雌側爪領域２２Ｂ３の先端を滑動するように第一係合部２３の係合が外れる。同様に、第二係合部２４についても、雄側鉤部２１Ｃの雄側鉤状領域２１Ｃ１と雌側鉤部２２Ｃの雌側鉤状領域２２Ｃ１とが外れる方向に移動されて外れ、開口部１２が小さな力で容易に開封できる。 (When opened)
On the other hand, when opening, the top seal portion is removed and the opening 12 is opened. And as shown in FIG. 6, the edge of the opening part 12 is pulled in the arrow direction which mutually spaces apart. Thus, the male side belt-like base portion 21A and the female side belt-like base portion 22A are bent so as to be bent.
Therefore, the male claw region 21B2 of the male part 21B and the female claw region 22B3 of the female part 22B are moved away from each other, and the tip of the male claw region 21B2 and the tip of the male part 21B are the female claw of the female part 22B. The first engagement portion 23 is disengaged so as to slide on the tip of the region 22B3. Similarly, the second engagement portion 24 is also moved away from the male side flanged region 21C1 of the male side flange 21C and the female side flanged region 22C1 of the female side flange 22C, and the opening 12 Can be opened easily with a small force.
［実施形態の効果］
　上述したように、上記実施形態では、袋本体１０の内圧が増大した際、一対の帯状基部２１Ａ，２２Ａの幅方向の両端側を袋本体１０に取り付けた状態では、第二係合部２４の基端に圧力が作用し、薄肉部２２Ａ１が切断する。このことにより、雌側帯状基部２２Ａは、幅方向における他端側である開口部１２に対応する側のみが袋本体１０に取り付けられた状態となり、高い封止性と易開封性との相反する双方が得られるいわゆる片側外しの状態となる。
　このため、高い封止性と易開封性とが得られる構成が、薄肉部２２Ａ１を設けた簡単な構造のジッパーテープ２０を用い、一対の帯状基部２１Ａ，２２Ａの幅方向の両端側を袋本体１０に取り付ける通常の取付方法でも容易に得られ、製造性も向上できる。 [Effect of the embodiment]
As described above, in the above embodiment, when the internal pressure of the bag body 10 is increased, the second engaging portion 24 of the pair of band- like base portions 21A and 22A is attached to the bag body 10 at both ends in the width direction. Pressure acts on the proximal end, and the thin portion 22A1 is cut. Accordingly, only the side corresponding to the opening 12 which is the other end side in the width direction of the female side band-shaped base 22A is attached to the bag body 10, and there is a contradiction between high sealing performance and easy opening. It will be in the state of what is called one side removal from which both are obtained.
For this reason, the structure which can obtain high sealing performance and easy opening uses the zipper tape 20 of the simple structure which provided the thin part 22A1, and the both ends of the width direction of a pair of strip | belt-shaped base parts 21A and 22A are bag bodies. 10 can be easily obtained by a normal attachment method, and the productivity can be improved.
　そして、上記実施形態では、第一係合部２３および第二係合部２４をそれぞれ設けている。
　このため、雄側鉤部２１Ｃおよび雌側鉤部２２Ｃの係合と合わせて、雄部２１Ｂおよび雌部２２Ｂの係合により、開封性があまり損なわれることなく、係合力を大きく増大でき、より高い封止性が得られる。 And in the said embodiment, the 1st engaging part 23 and the 2nd engaging part 24 are each provided.
For this reason, together with the engagement of the male side collar part 21C and the female side collar part 22C, the engagement force can be greatly increased by the engagement of the male part 21B and the female part 22B, without much impairing the opening. High sealing performance is obtained.
　さらに、切断可能領域として薄肉部２２Ａ１としている。
　このため、内圧が作用した際に切断して片側外しの構成が、薄肉に形成する簡単な構成で容易に得られる。 Further, the thin portion 22A1 is used as a cuttable region.
For this reason, when the internal pressure is applied, it is possible to easily obtain a structure that is cut off on one side and is formed thinly.

Accordingly, the description of the materials, layer structures, and the like disclosed above is exemplary for easy understanding of the present invention, and does not limit the present invention. Descriptions with names excluding some or all of the limitations are included in the present invention.
　例えば、上記実施形態では、第一係合部２３および第二係合部２４を設けたジッパーテープ２０を例示したが、例えば、図７に示すように、第二係合部２４を設けず第一係合部２３のみとし、雌部２２Ｂの基端に、切断可能領域を設けてもよい。 For example, in the above embodiment, the zipper tape 20 provided with the first engaging portion 23 and the second engaging portion 24 is illustrated, but for example, as shown in FIG. Only one engaging portion 23 may be provided, and a cutable region may be provided at the proximal end of the female portion 22B.
　さらに、ジッパーテープ２０としては、第一係合部２３や第二係合部２４を複数対設けてもよい。
　このような構成とすることで、より係合力が向上し、高い封止性が得られる。
　なお、この場合には、切断可能領域より収納空間１４側には、他の第一係合部２３や第二係合部２４は設けられていない構成とする必要がある。具体的には、第一係合部２３を複数対設けた構成では、図８に示すように、最も収納空間１４側に位置する雌部２２Ｂの収納空間１４側の基端に、切断可能領域（例えば、薄肉部２２Ａ１）を設ける必要がある。第二係合部２４を複数対設けた構成も同様に、最も収納空間１４側に位置する雌側鉤部２２Ｃの収納空間１４側の基端に、切断可能領域を設ける必要がある。 Furthermore, as the zipper tape 20, a plurality of pairs of the first engaging portion 23 and the second engaging portion 24 may be provided.
By setting it as such a structure, engagement force improves more and high sealing performance is obtained.
In this case, it is necessary that the other first engagement portion 23 and the second engagement portion 24 are not provided on the storage space 14 side from the cuttable region. Specifically, in the configuration in which a plurality of pairs of the first engagement portions 23 are provided, as shown in FIG. It is necessary to provide (for example, the thin portion 22A1). Similarly, in the configuration in which a plurality of pairs of the second engaging portions 24 are provided, it is necessary to provide a severable region at the base end on the storage space 14 side of the female flange portion 22C located closest to the storage space 14 side.
　また、本発明では、切断可能領域が設けられる帯状基部２１Ａ，２２Ａには、例えば図９に示すように、ヒートシールの際に基材フィルム１１に取り付けられる接合領域としての接合突起２１Ａ２，２２Ａ２が、切断可能領域、例えば薄肉部２２Ａ１より幅方向の一端側に位置して設けられることが好ましい。この図９に示すような帯状基部２１Ａ，２２Ａの幅方向の両端側に、積極的にシールされる接合突起２１Ａ２，２２Ａ２を設けることで、内圧が作用して切断可能領域で切断された際に、確実に片側外しの構成が得られ、内圧に対して高い封止性が確実に得られる。 Moreover, in this invention, as shown to FIG. 9, for example, as shown in FIG. 9, joining protrusion 21A2, 22A2 as a joining area | region attached to the base film 11 is shown in strip | belt-shaped base part 21A, 22A provided with a cutting | disconnection area | region. In addition, it is preferable to be provided on one end side in the width direction from the cuttable region, for example, the thin portion 22A1. By providing the joining protrusions 21A2 and 22A2 that are positively sealed at both ends in the width direction of the band-shaped base portions 21A and 22A as shown in FIG. 9, when the internal pressure acts and the cut portions are cut in the cuttable region. Thus, a structure with one side removed can be obtained with certainty, and high sealing performance against the internal pressure can be obtained with certainty.
　さらに、本発明では、例えば図９に示すように、雄側鉤部２１Ｃや雌側鉤部２２Ｃが変形した際に当接可能に補強部２５を設けてもよい。さらに、雄部２１Ｂや雌部２２Ｂが変形した際に当接可能に補強部２５を設けてもよい。
　このような補強部２５を設けることで、例えば、ジッパーテープ付袋体１に大きな内圧が作用し、雄側鉤部２１Ｃや雌側鉤部２２Ｃが変形したり、雄部２１Ｂや雌部２２Ｂが変形したりすると、補強部２５に当接して変形が抑制される。このため、係合が解除されてしまうことを防止でき、より高い封止性を提供できる。 Furthermore, in the present invention, for example, as shown in FIG. 9, the reinforcing portion 25 may be provided so as to be able to come into contact when the male side collar 21 </ b> C and the female side collar 22 </ b> C are deformed. Furthermore, you may provide the reinforcement part 25 so that contact | abutment is possible when the male part 21B and the female part 22B deform | transform.
By providing such a reinforcing part 25, for example, a large internal pressure acts on the bag body 1 with a zipper tape, the male side collar part 21C and the female side collar part 22C are deformed, or the male part 21B and the female part 22B are deformed. When it is deformed, the deformation is suppressed by coming into contact with the reinforcing portion 25. For this reason, it can prevent that engagement is cancelled | released and can provide higher sealing performance.
　そして、切断可能領域としては、薄肉部２２Ａ１に限らない。例えば、小穴が連続する目打ち部、帯状基部２１Ａ，２２Ａの他の部位より軟質の部材にて形成された軟質部、これらの組み合わせのいずれの構成としてもよい。 Further, the cuttable region is not limited to the thin portion 22A1. For example, the structure may be any of a perforated portion where small holes are continuous, a soft portion formed of a member softer than other portions of the belt- like base portions 21A and 22A, and a combination thereof.
