Description

本発明は、ジッパーテープ付袋体に関する。 The present invention relates to a bag with a zipper tape.

近年、被包装物を収納する袋体を開封した後、再封止可能としたジッパーテープ付袋体が広く利用されている。このようなジッパーテープ付袋体として、開封を補助する摘みを有した構成が知られている（例えば、特許文献１参照）。
特許文献１に記載のジッパーテープ付袋体は、被包装物を収納する収納空間を内部に有した袋本体を備え、この袋本体の開封された開口縁の内側に、係脱可能で開口を再封止するジッパーテープが設けられている。そして、袋本体の外面には、開口縁近傍に位置して舌片状に設けられた開封補助摘みが設けられている。そして、この開封補助摘みを持って開口縁を引っ張ることで、ジッパーテープの係合が解除され、袋本体が開封される構成が採られている。 In recent years, a bag with a zipper tape that can be resealed after opening a bag for storing an object to be packaged has been widely used. As such a bag body with a zipper tape, a configuration having a knob for assisting opening is known (see, for example, Patent Document 1).
The bag body with a zipper tape described in Patent Document 1 includes a bag body having a storage space for storing an object to be packaged inside, and has a removable opening inside the opened opening edge of the bag body. A zipper tape for resealing is provided. The outer surface of the bag body is provided with an opening auxiliary knob located near the opening edge and provided in the shape of a tongue piece. Then, by pulling the opening edge with the opening auxiliary knob, the zipper tape is disengaged and the bag body is opened.

特開２０１１－１４０３２６号公報JP 2011-140326A

ところで、被包装物の内容によっては、幼児や子供の手の届かない場所に保管することが好ましい。しかしながら、誤って幼児や子供の手が触れることがある。従来の開封を容易とする開封補助摘みを備えた構成では、幼児や子供でも容易に開封できてしまう不都合がある。
本発明は、不用意な開封を防止するジッパーテープ付袋体を提供することを目的とする。 By the way, depending on the contents of the packaged object, it is preferable to store it in a place out of reach of infants and children. However, it may be accidentally touched by infants or children. In the conventional configuration provided with an opening auxiliary knob that facilitates opening, there is an inconvenience that even infants and children can easily open the opening.
An object of the present invention is to provide a bag with a zipper tape to prevent inadvertent opening.

本発明のジッパーテープ付袋体は、被包装物を収納可能な収納空間を有する袋本体と、前記袋本体の内面に接合されたジッパーテープと、を具備し、前記ジッパーテープは、一対の雄側鉤部および雌側鉤部が互いに係合可能な係合部と、前記係合部にそれぞれ連設する一対の帯状基部とを備え、前記雄側鉤部または前記雌側鉤部を有する帯状基部の一方には、前記帯状基部の幅方向における前記収納空間とは反対側の前記係合部の基端に位置して、屈曲部が設けられ、前記一対の帯状基部は、それぞれ前記袋本体に接合されていることを特徴とする。 The bag body with a zipper tape of the present invention includes a bag body having a storage space capable of storing an object to be packaged, and a zipper tape bonded to the inner surface of the bag body, and the zipper tape is a pair of males. A band-shaped portion having an engaging portion in which the side hook portion and the female side hook can be engaged with each other and a pair of band-shaped bases connected to the engaging portion, respectively, and having the male-side hook portion or the female-side hook portion. One of the bases is provided with a bent portion located at the base end of the engaging portion on the side opposite to the storage space in the width direction of the strip-shaped base, and the pair of strip-shaped bases are each the bag main body. It is characterized by being joined to.

この発明では、袋本体の開口部の縁を摘んで開口部を広げるように開封する通常の開封方法では、屈曲部の位置で帯状基部が屈曲するので、一対の帯状基部に沿って一対の帯状基部を剪断させる方向に開封力が作用することとなり、雄側鉤部および雌側鉤部が強く係合して、開封が抑制される。
一方、例えば、屈曲部が設けられていない帯状基部が設けた袋本体の外面（帯状基部より収納空間側）と、屈曲部が設けられた帯状基部が設けた袋本体の開口部の縁とを摘んで袋本体を広げるように引っ張ると、あるいは、袋本体の外面における帯状基部より収納空間側と帯状基部より開口部側とを互いに離間する方向に、指でスライドさせると、一対の帯状基部が離間して雄側鉤部および雌側鉤部の係合を解除するように開封力が作用し、容易に開封できる。
したがって、開封するためには特別な開封作業が必要となり、誤開封を防止できる。 In the present invention, in the normal opening method of picking the edge of the opening of the bag body and opening the bag so as to widen the opening, the band-shaped base bends at the position of the bent portion. The opening force acts in the direction of shearing the base, and the male side hook portion and the female side hook portion are strongly engaged with each other, and the opening is suppressed.
On the other hand, for example, the outer surface of the bag body provided with the band-shaped base without the bent portion (on the storage space side from the band-shaped base) and the edge of the opening of the bag body provided with the band-shaped base provided with the bent portion. If you pick it up and pull it to spread the bag body, or slide it with your finger in the direction that separates the storage space side from the band-shaped base and the opening side from the band-shaped base on the outer surface of the bag body, a pair of band-shaped bases will be created. The opening force acts so as to disengage the male side and female side bags apart from each other, and the bag can be easily opened.
Therefore, special opening work is required to open the package, and erroneous opening can be prevented.

ここで、袋本体としては、例えば、一枚のフィルムを折り曲げて製造される構成、二枚のフィルムを重ね合わせて製造される構成、もしくは二枚以上のフィルムを用いて側面にマチを設けたガゼット袋やスタンディング袋など、種々形態のものが適用できる。
そして、帯状基部の袋本体との接合としては、ヒートシールの他、超音波による溶着、接着剤などを用いた接着など、帯状基部を袋本体に取り付ける各種方法を利用できる。
また、屈曲部としては、例えば他の部分に比べて薄肉、欠落、破線状に孔を連ねたいわゆるミシン目である目打ち、破線状に凹部を連ねたものなどの他、他の部分より柔らかい部材にて形成したり、蛇腹形状など、その部分で帯状基部が屈曲しやすい構成である。 Here, as the bag main body, for example, a structure manufactured by bending one film, a structure manufactured by superimposing two films, or a gusset is provided on a side surface using two or more films. Various forms such as a gusset bag and a standing bag can be applied.
As the joining of the band-shaped base to the bag body, various methods of attaching the band-shaped base to the bag body can be used, such as heat sealing, welding by ultrasonic waves, and adhesion using an adhesive or the like.
In addition, the bent portion includes, for example, a thin wall, a chip, a perforation which is a so-called perforation in which holes are connected in a broken line shape, a member in which concave portions are connected in a broken line shape, and a member softer than other parts. The band-shaped base is easily bent at that part, such as the shape of a bellows or a bellows shape.

そして、本発明では、前記屈曲部が設けられた帯状基部は、幅方向における前記係合部が設けられた位置よりも、前記収納空間側がさらに前記袋本体に接合されている構成とすることもできる。
この発明では、例えば、開口され縁を摘んで無理に開封しようと大きな開封力を作用させると、屈曲部に大きな開封力が作用することとなる。このため、大きな開封力により屈曲部が切断されることで、開封された形跡を容易に判明できる。 Further, in the present invention, the band-shaped base portion provided with the bent portion may be configured such that the storage space side is further joined to the bag body from the position where the engaging portion is provided in the width direction. can.
In the present invention, for example, when a large opening force is applied to forcibly open the package by pinching the edge of the opening, a large opening force is applied to the bent portion. Therefore, since the bent portion is cut by a large opening force, the evidence of opening can be easily found.

また、本発明では、前記屈曲部は、当該屈曲部が設けられた帯状基部の厚さより薄肉に形成されている構成とすることもできる。
この発明では、屈曲部を薄肉とする簡単な構造で、屈曲部の位置で屈曲する構成が得られる。 Further, in the present invention, the bent portion may be formed to be thinner than the thickness of the band-shaped base provided with the bent portion.
In the present invention, it is possible to obtain a structure in which the bent portion is bent at the position of the bent portion with a simple structure in which the bent portion is made thin.

さらに、本発明では、前記屈曲部は、前記袋本体の内面から離間されている構成とすることもできる。
この発明では、袋本体の内面から屈曲部を離間する構成とすることで、袋本体の内面に沿ってジッパーテープが融着されていない空隙部分が存在するため、この空隙部分に接する袋本体が屈曲しやすくなり、それに伴って、屈曲部も同時に屈曲する。したがって、屈曲部の位置でより小さい力で袋本体とともに屈曲することが可能となる。 Further, in the present invention, the bent portion may be configured to be separated from the inner surface of the bag body.
In the present invention, the bent portion is separated from the inner surface of the bag body, so that there is a gap portion in which the zipper tape is not fused along the inner surface of the bag body. It becomes easy to bend, and the bent portion also bends at the same time. Therefore, it is possible to bend together with the bag body with a smaller force at the position of the bent portion.

また、本発明では、前記屈曲部は、破線状に連なる複数の孔または凹部である構成とすることもできる。
この発明では、屈曲部を破線状に連なる複数の孔または凹部とする簡単な構造で、屈曲部の位置で屈曲する構成が得られる。 Further, in the present invention, the bent portion may be configured to be a plurality of holes or recesses connected in a broken line shape.
In the present invention, it is possible to obtain a configuration in which the bent portion is bent at the position of the bent portion with a simple structure in which the bent portion is formed into a plurality of holes or recesses connected in a broken line shape.

そして、本発明では、前記屈曲部は、前記雄側鉤部が設けられた帯状基部に設けられている構成とすることもできる。
ここで、雌側鉤部が設けられた帯状基部に屈曲部を設けた場合、雄側鉤部が設けられた帯状基部に設けた場合と逆側にせん断力が働く。このため、開封できるようにするためには、第一雄側爪の掛かりを少なくする必要がある。そうすると内圧に対して弱くなるため、屈曲部は雄側に設けることが好ましい。 Further, in the present invention, the bent portion may be configured to be provided on the band-shaped base portion provided with the male side hook portion.
Here, when the bent portion is provided in the band-shaped base provided with the female side hook portion, a shearing force acts on the opposite side to the case where the bent portion is provided in the strip-shaped base provided with the male side hook portion. Therefore, in order to be able to open the package, it is necessary to reduce the hooking of the first male side claw. Then, since it becomes weak against the internal pressure, it is preferable to provide the bent portion on the male side.

また、本発明では、前記雄側鉤部は、前記収納空間側に突出する第一雄側爪と、前記第一雄側爪とは反対側に突出する第二雄側爪と、を有し、前記雌側鉤部は、前記第一雄側爪が係合可能な第一雌側爪と、前記第二雄側爪が係合可能な第二雌側爪と、を有し、前記第一雄側爪は、前記雄側鉤部が設けられた帯状基部に対向する斜面を有し、前記斜面の接線と、前記雄側鉤部が設けられた帯状基部の垂線とのなす角αが９０°より小さい角度に形成され、前記第二雄側爪は、前記雄側鉤部が設けられた帯状基部に対向する斜面を有し、前記斜面の接線と、前記雄側鉤部が設けられた帯状基部の垂線とのなす角βが９０°より大きい角度に形成されている構成とすることもできる。
この発明では、収納空間側に突出する第一雄側爪は断面鉤形状に突出し、第一雄側爪とは反対側に突出する第二雄側爪は断面山形状に突出する形状とすることができる。このため、開封された袋本体の縁を開く通常の開封する方法には、一対の帯状基部を剪断させる方向に開封力が作用し、第一雄側爪と第一雌側爪とが強く係合し、誤開封を防止できる。一方、屈曲部が設けられていない帯状基部が設けた袋本体の外面（帯状基部より収納空間側）と、屈曲部が設けられた帯状基部が設けた袋本体の開口部の縁とを摘んで袋本体を広げるように引っ張ると、第二雄側爪および第二雌側爪は互いに離れて係合が外れる状態となり、容易に係合解除ができる。 Further, in the present invention, the male side hook portion has a first male side claw that protrudes toward the storage space side and a second male side claw that protrudes on the side opposite to the first male side claw. The female side hook portion has a first female side claw to which the first male side claw can engage and a second female side claw to which the second male side claw can engage. The male-side claw has a slope facing the band-shaped base provided with the male-side hook, and an angle α formed by the tangent line of the slope and the vertical line of the band-shaped base provided with the male hook is formed. Formed at an angle smaller than 90 °, the second male side claw has a slope facing the band-shaped base provided with the male side hook portion, and is provided with a tangent line of the slope and the male side hook portion. It is also possible to configure the angle β formed by the vertical line of the strip-shaped base to be larger than 90 °.
In the present invention, the first male side claw protruding toward the storage space has a shape protruding in the shape of a cross-sectional hook, and the second male side claw protruding on the side opposite to the first male side claw has a shape protruding in the shape of a mountain cross section. Can be done. For this reason, in the normal opening method of opening the edge of the opened bag body, the opening force acts in the direction of shearing the pair of band-shaped bases, and the first male side nail and the first female side nail are strongly engaged. In addition, it is possible to prevent erroneous opening. On the other hand, the outer surface of the bag body provided with the band-shaped base without the bent portion (the storage space side from the band-shaped base) and the edge of the opening of the bag body provided with the band-shaped base provided with the bent portion are picked. When the bag body is pulled so as to spread, the second male side claw and the second female side claw are separated from each other and disengaged, and the engagement can be easily disengaged.

さらに、本発明では、前記ジッパーテープは、前記係合部を複数対有している構成とすることもできる。
この発明では、係合部を複数対設けることもできる。このことにより、係合力が増大し、より誤開封を防止できるとともに、封止性を向上できる。
ここで、複数対の係合部は、同一形状に限られるものではない。 Further, in the present invention, the zipper tape may have a configuration having a plurality of pairs of the engaging portions.
In the present invention, a plurality of pairs of engaging portions may be provided. As a result, the engaging force can be increased, erroneous opening can be prevented, and the sealing property can be improved.
Here, the plurality of pairs of engaging portions are not limited to the same shape.

また、本発明では、前記袋本体の外面には、前記一対の帯状基部のうち前記屈曲部が設けられていない帯状基部が前記袋本体に取り付けられた位置に対して、前記収納空間側に位置して把持部が設けられている構成とすることもできる。
この発明では、屈曲部が設けられた帯状基部が接合された袋本体の開口された縁と、把持部とを持って袋本体を引っ張ることで、雄側鉤部および雌側鉤部の係合を解除するように開封力が作用する。このため、把持部を持って引っ張る簡単な作業で、容易に開封できる。 Further, in the present invention, on the outer surface of the bag body, the band-shaped base of the pair of band-shaped bases having no bent portion is located on the storage space side with respect to the position where the bag body is attached. It is also possible to have a configuration in which a grip portion is provided.
In the present invention, the male side hook portion and the female side hook portion are engaged by pulling the bag body by holding the open edge of the bag body to which the band-shaped base provided with the bent portion is joined and the grip portion. The opening force acts to release. Therefore, the package can be easily opened by a simple operation of holding and pulling the grip portion.

また、基材フィルム１１Ａ，１１Ｂ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、屈曲部が屈曲しないため、袋の開封がしにくくなる場合がある。 The base films 11A and 11B include, for example, a single-layer or multi-layer film formed of a thermoplastic resin such as (Linear Low Density Polyethylene: LLDPE) or polypropylene (PP). Can be used. As the multilayer film, biaxially stretched polypropylene (Oriented Polypropylene: OPP), biaxially stretched polyethylene terephthalate (OPET), biaxially stretched nylon (ONy), cast polypropylene (CPP), etc. are used as the surface substrate. Can be used. The multilayer film may be configured to include an inorganic layer such as aluminum vapor deposition or aluminum foil lamination for the purpose of so-called gas barrier or light shielding.
The base films 11A and 11B are not particularly limited as long as they are materials for packaging bags, 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 sealing strength and the bag strength may be weakened. On the other hand, if the thickness dimension exceeds 200 μm, the bent portion does not bend, which may make it difficult to open the bag.

（ジッパーテープ付袋体の製造方法）
次に、ジッパーテープ付袋体１の被包装物Ｐを収納する前のジッパーテープ付袋１Ａを、上記製造装置５を用いて製造する製造方法について、図面を参照して説明する。 (Manufacturing method of bag with zipper tape)
Next, a manufacturing method for manufacturing the bag 1A with the zipper tape before storing the packaged object P of the bag body 1 with the zipper tape by using the manufacturing apparatus 5 will be described with reference to the drawings.

ジッパーテープ付袋１Ａの製造方法は、例えば図４に示す三方製袋する製造装置５を用いて製造され、フィルム１１を供給するフィルム供給工程と、ジッパーテープ２０を供給するテープ供給工程と、雄部材２１と雌部材２２とを、基材フィルム１１Ａ，１１Ｂにそれぞれヒートシールする取付工程と、基材フィルム１１Ａ，１１Ｂからジッパーテープ付袋１Ａを形成させる製袋工程と、などを実施する。 The method for manufacturing the bag 1A with a zipper tape is, for example, a film supply step for supplying the film 11 and a tape supply step for supplying the zipper tape 20, which are manufactured by using the three-way bag manufacturing apparatus 5 shown in FIG. A mounting step of heat-sealing the member 21 and the female member 22 to the base films 11A and 11B, respectively, and a bag making step of forming a bag 1A with a zipper tape from the base films 11A and 11B are performed.

まず、フィルム１１を巻回したフィルム巻取ロール１１１をフィルム供給部５１に装着しておく。
また、雌部材２２と、雄部材２１とを、それぞれ押出成形などによって成形しておく。そして、雌部材２２の雌部２２Ｂと、雄部材２１の雄部２１Ｂとが係合され、一体のジッパーテープ２０としてテープ巻取ロール５２１に巻回し、テープ巻取ロール５２１をテープ供給部５２に装着しておく。 First, the film take-up roll 111 around which the film 11 is wound is attached to the film supply unit 51.
Further, the female member 22 and the male member 21 are respectively molded by extrusion molding or the like. Then, the female portion 22B of the female member 22 and the male portion 21B of the male member 21 are engaged with each other and wound around the tape winding roll 521 as an integral zipper tape 20, and the tape winding roll 521 is attached to the tape supply unit 52. Put it on.

そして、フィルム供給工程では、フィルム巻取ロール１１１から供給されるフィルム１１を、切断刃などにより、フィルム１１の送り出し方向に対して、交差する方向で二等分するようにフィルム１１を切断する。この切断により、基材フィルム１１Ａ，１１Ｂが切り出され、下流側に送り出される。 Then, in the film supply step, the film 11 supplied from the film take-up roll 111 is cut by a cutting blade or the like so as to bisect the film 11 in a direction intersecting the feeding direction of the film 11. By this cutting, the base films 11A and 11B are cut out and sent out to the downstream side.

また、テープ供給工程では、フィルム供給工程で二枚に重ね合わされて送り出された基材フィルム１１Ａ，１１Ｂ間に、テープ巻取ロール５２１から引き出されたジッパーテープ２０を送り出す。
取付工程では、雄部材２１および雌部材２２の幅方向の両端部分を、シールバー５４１により、一方の基材フィルム１１Ａ，１１Ｂにそれぞれ接合、すなわちヒートシールする。
製袋工程では、取付工程で雄部材２１および雌部材２２が取り付けられた基材フィルム１１Ａ，１１Ｂに、ボトムシールバー５４３によりボトムシール部１３を形成して底面部１０Ｂを設けた後、サイドシールバー５４４によりサイドシール部１２を形成して一対の側面部１０Ａをそれぞれ設け、ジッパーテープ２０が取り付けられたガゼット形状の袋本体１０を製袋し、ジッパーテープ付袋１Ａが製造される。
そして、得られたジッパーテープ付袋１Ａは、次工程の充填工程により、開口する図示しない投入口から被包装物Ｐが投入された後、投入口の縁に、トップシール部１４および持ち手１４Ａが設けられて投入口が封止される。この充填工程により、被包装物Ｐを収納したジッパーテープ付袋体１が得られる。 Further, in the tape supply step, the zipper tape 20 drawn from the tape take-up roll 521 is sent out between the base films 11A and 11B which are overlapped and sent out in the film supply step.
In the mounting step, both ends of the male member 21 and the female member 22 in the width direction are joined to one of the base films 11A and 11B by the seal bar 541, that is, heat-sealed, respectively.
In the bag making step, the bottom seal portion 13 is formed by the bottom seal bar 543 on the base films 11A and 11B to which the male member 21 and the female member 22 are attached in the attachment step, and then the bottom seal portion 10B is provided, and then the side seal is provided. A side seal portion 12 is formed by a bar 544, a pair of side surface portions 10A are provided, and a gusset-shaped bag body 10 to which a zipper tape 20 is attached is manufactured, and a bag 1A with a zipper tape is manufactured.
Then, in the obtained bag 1A with zipper tape, after the packaged object P is charged from the opening opening (not shown) in the filling step of the next step, the top seal portion 14 and the handle 14A are placed on the edge of the charging port. Is provided and the input port is sealed. By this filling step, a bag body 1 with a zipper tape containing the packaged object P is obtained.

｛ジッパーテープ付袋体の使用｝
次に、上記ジッパーテープ付袋体１の使用状況を説明する。
図５には、開口された縁を持って開封する際の誤開封防止の状況を示す要部断面が示されている。図６には、開口された縁と袋本体の外面とを持って開封する際の開封状況を示す要部断面が示され、（Ａ）は開封力を作用させた状態、（Ｂ）は係合部の係合が解除された状態である。 {Use of bag with zipper tape}
Next, the usage status of the bag body 1 with the zipper tape will be described.
FIG. 5 shows a cross section of a main part showing a situation of preventing erroneous opening when opening with an opened edge. FIG. 6 shows a cross section of a main part showing an opening state when opening by holding an opened edge and an outer surface of a bag body, (A) is a state in which an opening force is applied, and (B) is engaged. The engagement of the joint is disengaged.

まず、使用者がジッパーテープ付袋体１から被包装物を最初に取り出すにあっては、図５に示すように、ノッチ１７から基材フィルム１１Ａ，１１Ｂを引き裂いて、トップシール部１４側を切除することで開口部１８が形成されて開封される。
ここで、子供が興味本位で開封したり、改竄目的などで開封したりする場合など、通常の開口部１８の対向する縁を持って、開口部１８を広げて係合部２３の係合を解除しようとした場合、誤開封が防止される。具体的には、図５に示すように、雄側帯状基部２１Ａに設けられた屈曲部２１Ｃが折れ曲がるように開口部１８が広げられ、図５中の矢印で示す方向に引っ張り力が作用する。このため、開封のための引っ張り力は、雄側帯状基部２１Ａと雌側帯状基部２２Ａとの平面に沿って、雄側帯状基部２１Ａと雌側帯状基部２２Ａとを剪断させる方向に力が作用する。したがって、断面鉤形状の第一雄側爪２１Ｂ１と第一雌側爪２２Ｂ１とが互いに噛み合う状態となり、第一雄側爪２１Ｂ１と第一雌側爪２２Ｂ１とが強く係合し、誤開封や改竄のための開封が防止される。
このように、化粧品や薬品など、あるいは細かい部品など、幼児や子供から遠ざけておきたい物などが誤開封されて取り出されてしまったり、改竄を目的として開封されてしまったりすること防止できる。 First, when the user first takes out the packaged object from the bag body 1 with the zipper tape, as shown in FIG. 5, the base films 11A and 11B are torn from the notch 17 to remove the top seal portion 14 side. By excising, the opening 18 is formed and opened.
Here, when the child opens the package for the purpose of interest or falsification, the opening 18 is widened to engage the engaging portion 23 with the facing edges of the normal opening 18. If you try to release it, erroneous opening will be prevented. Specifically, as shown in FIG. 5, the opening 18 is widened so that the bent portion 21C provided in the male side strip-shaped base 21A bends, and a pulling force acts in the direction indicated by the arrow in FIG. Therefore, the pulling force for opening acts in the direction of shearing the male-side strip-shaped base 21A and the female-side strip-shaped base 22A along the plane of the male-side strip-shaped base 21A and the female-side strip-shaped base 22A. .. Therefore, the first male-side claw 21B1 and the first female-side claw 22B1 having a hook-shaped cross section are in a state of meshing with each other, and the first male-side claw 21B1 and the first female-side claw 22B1 are strongly engaged with each other, resulting in erroneous opening or falsification. Is prevented from opening.
In this way, it is possible to prevent cosmetics, chemicals, small parts, and other items that should be kept away from infants and children from being erroneously opened and taken out, or opened for the purpose of falsification.

一方、袋本体１０に予め収納された被包装物Ｐの利用者が被包装物Ｐを取り出すため、あるいは、袋本体１０に被包装物Ｐを新たに収納するため、係合部２３の係合を解除する場合には、特異な開封方法が実施される。すなわち、屈曲部２１Ｃを有しない雌側帯状基部２２Ａがヒートシールされた袋本体１０の外面、具体的には雌側帯状基部２２Ａより収納空間１０Ｃ側の外面と、屈曲部２１Ｃを有する雄側帯状基部２１Ａがヒートシールされた袋本体１０の開口部１８の縁とを摘んで、袋本体１０を広げるように引っ張る。なお、摘む位置としては、例えば袋本体１０に印刷などにより示されていると、利用者は開封作業が容易となる。
この袋本体１０を広げる引っ張り力は、図６（Ａ）中の矢印に示すように作用し、第二雄側爪２１Ｂ２と第二雌側爪２２Ｂ２とが引っ掛かり合う状態となる。この図６（Ａ）に示す状態では、第二雄側爪２１Ｂ２が断面山形状のため、引っ張り力は第二雄側爪２１Ｂ２が第二雌側爪２２Ｂ２を乗り越えるように作用し、比較的に小さい力で係合部２３の係合を解除できる。
なお、袋本体１０の外面、すなわち、雌側帯状基部２２Ａより収納空間１０Ｃ側の外面と、雄側帯状基部２１Ａより開口部１８側の外面とを、互いに離間する方向に、指でスライドさせても、同様に開封できる。
そして、被包装物Ｐを取り出しあるいは収納した後は、再び雄部２１Ｂおよび雌部２２Ｂを係合させることで、袋本体１０は再封止される。 On the other hand, in order for the user of the packaged object P previously stored in the bag body 10 to take out the packaged object P, or to newly store the packaged object P in the bag body 10, the engaging portion 23 is engaged. When releasing, a peculiar opening method is implemented. That is, the outer surface of the bag body 10 in which the female side strip-shaped base 22A having no bent portion 21C is heat-sealed, specifically, the outer surface on the storage space 10C side from the female-side strip-shaped base 22A, and the male side strip having the bent portion 21C. The base 21A picks up the edge of the opening 18 of the heat-sealed bag body 10 and pulls the bag body 10 so as to spread it. If the position to be picked is indicated by printing on the bag body 10, for example, the user can easily open the bag.
The pulling force that spreads the bag body 10 acts as shown by the arrow in FIG. 6A, and the second male side claw 21B2 and the second female side claw 22B2 are in a state of being caught. In the state shown in FIG. 6 (A), since the second male side claw 21B2 has a mountain shape in cross section, the pulling force acts so that the second male side claw 21B2 gets over the second female side claw 22B2, and is relatively relatively. The engaging portion 23 can be disengaged with a small force.
The outer surface of the bag body 10, that is, the outer surface on the storage space 10C side from the female side band-shaped base 22A and the outer surface on the opening 18 side from the male side band-shaped base 21A are slid with a finger in a direction away from each other. Can be opened in the same way.
Then, after the packaged object P is taken out or stored, the bag body 10 is resealed by engaging the male portion 21B and the female portion 22B again.

｛第一実施形態の効果｝
上述したように、上記第一実施形態では、雄側帯状基部２１Ａの幅方向における係合部２３の基端の開口部１８側に、屈曲部２１Ｃを設ける。そして、雄側帯状基部２１Ａおよび雌側帯状基部２２Ａの幅方向の開口部１８側を、袋本体１０の内面にヒートシールしている。
この構成により、袋本体１０の開口部１８の対向する縁を摘んで、開口部１８を広げるように開封する通常の開封方法では、屈曲部２１Ｃの位置で雄側帯状基部２１Ａが屈曲するので、雄側帯状基部２１Ａと雌側帯状基部２２Ａとを剪断させる方向に引っ張り力が作用する。このため、第一雄側爪２１Ｂ１および第一雌側爪２２Ｂ１が強く噛合して、係合部２３の係合が解除されることを防止できる。
したがって、開封するためには特別な開封作業が必要となり、誤開封を防止できる。 {Effect of the first embodiment}
As described above, in the first embodiment, the bent portion 21C is provided on the opening 18 side of the base end of the engaging portion 23 in the width direction of the male side strip-shaped base portion 21A. Then, the opening 18 side in the width direction of the male side band-shaped base 21A and the female side band-shaped base 22A is heat-sealed on the inner surface of the bag body 10.
With this configuration, in a normal opening method in which the facing edge of the opening 18 of the bag body 10 is picked and the opening 18 is opened so as to widen, the male side strip-shaped base 21A bends at the position of the bending portion 21C. A pulling force acts in the direction of shearing the male-side strip-shaped base 21A and the female-side strip-shaped base 22A. Therefore, it is possible to prevent the first male side claw 21B1 and the first female side claw 22B1 from being strongly engaged with each other and the engaging portion 23 from being disengaged.
Therefore, special opening work is required to open the package, and erroneous opening can be prevented.

そして、上記第一実施形態では、屈曲部２１Ｃを有する雄側帯状基部２１Ａは、幅方向における係合部２３の位置よりも収納空間１０Ｃ側が、さらに袋本体１０の内面にヒートシールされている。すなわち、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ヒートシールされた四点シールとされている。
このため、例えば、開口された開口部１８の縁を摘んで無理に開封しようとして、大きな開封力である引っ張り力を作用させた場合、薄肉の屈曲部２１Ｃに大きな引っ張り力が作用し、屈曲部２１Ｃが切断されてしまう。したがって、無理に開封しようとした形跡を容易に判明でき、改竄を防止できる。 In the first embodiment, the male side strip-shaped base portion 21A having the bent portion 21C is heat-sealed on the inner surface of the bag body 10 on the storage space 10C side of the position of the engaging portion 23 in the width direction. That is, the male-side strip-shaped base 21A and the female-side strip-shaped base 22A are four-point seals in which both ends in the width direction are heat-sealed.
For this reason, for example, when an attempt is made to forcibly open the opening by picking the edge of the opened opening 18 and a pulling force, which is a large opening force, is applied, a large pulling force acts on the thin-walled bent portion 21C, and the bent portion is bent. 21C will be disconnected. Therefore, it is possible to easily find evidence of an attempt to open the package and prevent falsification.

また、上記第一実施形態では、屈曲部２１Ｃを薄肉としている。
このため、薄肉とする簡単な構造で、屈曲部２１Ｃの位置で雄側帯状基部２１Ａが屈曲する構成が得られる。 Further, in the first embodiment, the bent portion 21C is made thin.
Therefore, it is possible to obtain a structure in which the male side strip-shaped base portion 21A is bent at the position of the bent portion 21C with a simple structure having a thin wall.

さらに、上記第一実施形態では、屈曲部２１Ｃを袋本体１０の内面から離間するように設けている。
このため、袋本体１０の内面に沿ってジッパーテープ２０が融着されていない空隙部分が存在するため、この空隙部分に接する袋本体１０が屈曲しやすくなり、それに伴って、屈曲部２１Ｃも同時に屈曲する。したがって、屈曲部２１Ｃの位置でより小さい力で袋本体１０とともに屈曲する状態が得られる。したがって、開口部１８の縁を持って係合部２３の係合を解除しようとした際、この時の引っ張り力が、雄側帯状基部２１Ａと雌側帯状基部２２Ａとを剪断させる方向に作用しやすくなる。よって、第一雄側爪２１Ｂ１および第一雌側爪２２Ｂ１が強く噛合する状態が得られ、より誤開封を防止できる。 Further, in the first embodiment, the bent portion 21C is provided so as to be separated from the inner surface of the bag main body 10.
Therefore, since there is a gap portion in which the zipper tape 20 is not fused along the inner surface of the bag body 10, the bag body 10 in contact with the gap portion is likely to bend, and the bent portion 21C also bends at the same time. Bend. Therefore, it is possible to obtain a state in which the bag body 10 is bent with a smaller force at the position of the bent portion 21C. Therefore, when an attempt is made to disengage the engaging portion 23 by holding the edge of the opening 18, the pulling force at this time acts in a direction of shearing the male-side strip-shaped base 21A and the female-side strip-shaped base 22A. It will be easier. Therefore, a state in which the first male side claw 21B1 and the first female side claw 22B1 are strongly meshed can be obtained, and erroneous opening can be further prevented.

また、上記第一実施形態では、収納空間１０Ｃ側に突出する第一雄側爪２１Ｂ１を断面鉤形状となるように形成し、第一雄側爪２１Ｂ１とは反対側に突出する第二雄側爪２１Ｂ２は断面鉤形状となるように形成している。
このため、開封された袋本体１０の開口部１８の縁を開くように開封する通常の開封方法では、屈曲部２１Ｃで雄側帯状基部２１Ａが屈曲し、雄側帯状基部２１Ａおよび雌側帯状基部２２Ａを剪断させる方向に引っ張り力が作用する。したがって、断面鉤形状の第一雄側爪２１Ｂ１と第一雌側爪２２Ｂ１とが強く噛合して、誤開封を防止できる。
一方、開封する場合には特異な開封方法で開封する。すなわち、雌側帯状基部２２Ａがヒートシールされた袋本体１０の雌側帯状基部２２Ａより収納空間１０Ｃ側と、屈曲部２１Ｃを有する雄側帯状基部２１Ａがヒートシールされた袋本体１０の開口部１８の縁とを摘んで、袋本体１０を広げるように引っ張る。すると、断面山形状の第二雄側爪２１Ｂ２および第二雌側爪２２Ｂ２は、互いに離れて係合が外れる状態となり、容易に係合を解除できる。このように、開封する場合には容易に開封できるとともに、誤開封をより防止できる。 Further, in the first embodiment, the first male side claw 21B1 projecting to the storage space 10C side is formed so as to have a hook shape in cross section, and the second male side projecting to the opposite side to the first male side claw 21B1. The claw 21B2 is formed so as to have a hook shape in cross section.
Therefore, in the normal opening method of opening the opened bag body 10 so as to open the edge, the male side band-shaped base 21A is bent at the bent portion 21C, and the male side band-shaped base 21A and the female side band-shaped base 21A are bent. A pulling force acts in the direction of shearing 22A. Therefore, the first male side claw 21B1 and the first female side claw 22B1 having a hook-shaped cross section are strongly engaged with each other to prevent erroneous opening.
On the other hand, when opening the package, it is opened by a peculiar opening method. That is, the storage space 10C side of the female side band-shaped base 22A of the bag body 10 in which the female side band-shaped base 22A is heat-sealed, and the opening 18 of the bag body 10 in which the male-side band-shaped base 21A having the bent portion 21C is heat-sealed. Pinch the edge of the bag and pull it to spread the bag body 10. Then, the second male-side claw 21B2 and the second female-side claw 22B2 having a mountain-shaped cross section are separated from each other and disengaged from each other, and the engagement can be easily disengaged. In this way, when the package is opened, it can be easily opened and erroneous opening can be further prevented.

そして、上記第一実施形態では、雄部材２１側に屈曲部２１Ｃを設けている。
ここで、雌部２２Ｂが設けられた雌側帯状基部２２Ａに屈曲部２１Ｃを設けた場合、雄部２１Ｂが設けられた雄側帯状基部２１Ａに設けた場合と逆側にせん断力が働く。このため、開封できるようにするためには、第一雄側爪２１Ｂ１の掛かりを少なくする必要がある。そうすると内圧に対して弱くなるため、屈曲部２１Ｃは雄部材２１側に設けることが好ましい。 In the first embodiment, the bent portion 21C is provided on the male member 21 side.
Here, when the bent portion 21C is provided on the female side strip-shaped base 22A provided with the female portion 22B, a shearing force acts on the opposite side to the case where the male portion 21B is provided on the male side strip-shaped base 21A. Therefore, in order to be able to open the package, it is necessary to reduce the hooking of the first male side claw 21B1. Then, since it becomes weak against the internal pressure, it is preferable to provide the bent portion 21C on the male member 21 side.

［第二実施形態］
次に、本発明の第二実施形態を図面に基づいて説明する。
図７には、第二実施形態におけるジッパーテープ付袋体の開封後の要部断面が示されている。
この第二実施形態では、第一実施形態における係合部の他に、さらに別の係合部としての係合鉤部を設けたものである。 [Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings.
FIG. 7 shows a cross section of a main part of the bag body with a zipper tape after opening in the second embodiment.
In this second embodiment, in addition to the engaging portion in the first embodiment, an engaging hook portion as another engaging portion is provided.

｛ジッパーテープの構成｝
具体的には、雄部材２１は、雄側帯状基部２１Ａと、雄部２１Ｂと、雄側鉤部２１Ｄとを有している。
雄側鉤部２１Ｄは、雄部２１Ｂより収納空間１０Ｃ側に位置して、雄部２１Ｂと平行に設けられている。なお、雄部２１Ｂと雄側鉤部２１Ｄとは、平行に限らない。例えば、互いに波形状に形成されたものなどでは並列状とされていればよい。
そして、雄側鉤部２１Ｄは、収納空間１０Ｃ側に突出する第三雄側爪２１Ｄ１を有している。第三雄側爪２１Ｄ１は、第一雄側爪２１Ｂ１と同様に、雄側帯状基部２１Ａに対向する収納側斜面２１Ｄ３を有し、この収納側斜面２１Ｄ３の接線２１Ｂ８と、雄側帯状基部２１Ａの垂線２１Ｂ５とのなす角γが、９０°より小さい角度の断面鉤形状に形成されている。 {Structure of zipper tape}
Specifically, the male member 21 has a male side band-shaped base portion 21A, a male portion 21B, and a male side hook portion 21D.
The male side hook portion 21D is located on the storage space 10C side of the male portion 21B and is provided in parallel with the male portion 21B. The male portion 21B and the male side hook portion 21D are not limited to parallel. For example, those formed in a wavy shape may be parallel to each other.
The male side hook portion 21D has a third male side claw 21D1 protruding toward the storage space 10C. Like the first male side claw 21B1, the third male side claw 21D1 has a storage side slope 21D3 facing the male side strip-shaped base 21A, and the tangent line 21B8 of the storage side slope 21D3 and the male side strip-shaped base 21A. The angle γ formed with the perpendicular line 21B5 is formed in the shape of a cross-sectional hook having an angle smaller than 90 °.

雌部材２２は、雌側帯状基部２２Ａと、雌部２２Ｂと、雄側鉤部２１Ｄと係合可能な雌側鉤部２２Ｄとを有している。
雌側鉤部２２Ｄは、第三雄側爪２１Ｄ１が係合可能に、開口部１８側に向けて突出する第三雌側爪２２Ｄ１を有している。
そして、ジッパーテープ２０は、雄側鉤部２１Ｄと雌側鉤部２２Ｄとにより、本発明の係合部としての係合鉤部２４が構成される。 The female member 22 has a female band-shaped base portion 22A, a female portion 22B, and a female side hook portion 22D that can engage with the male side hook portion 21D.
The female side hook portion 22D has a third female side claw 22D1 that projects toward the opening 18 side so that the third male side claw 21D1 can engage with the female side hook portion 22D.
The zipper tape 20 is composed of the male side hook portion 21D and the female side hook portion 22D to form the engaging hook portion 24 as the engaging portion of the present invention.

｛ジッパーテープ付袋体の使用｝
次に、上記ジッパーテープ付袋体１の使用状況を説明する。
図８には、開口された縁を持って開封する際の誤開封防止の状況を示す要部断面が示されている。図９には、開口された縁と袋本体の外面とを持って開封する際の開封状況を示す要部断面が示され、（Ａ）は開封力を作用させた状態、（Ｂ）は係合部の係合が解除された状態である。 {Use of bag with zipper tape}
Next, the usage status of the bag body 1 with the zipper tape will be described.
FIG. 8 shows a cross section of a main part showing a situation of preventing erroneous opening when opening with an opened edge. FIG. 9 shows a cross section of a main part showing the opening state when opening by holding the opened edge and the outer surface of the bag body, (A) is a state in which an opening force is applied, and (B) is engaged. The engagement of the joint is disengaged.

まず、使用者がジッパーテープ付袋体１から被包装物を最初に取り出すにあっては、図８に示すように、ノッチ１７から基材フィルム１１Ａ，１１Ｂを引き裂いて、トップシール部１４側を切除することで開口部１８が形成されて開封される。
ここで、子供が興味本位で開封したり、改竄目的などで開封したりする場合など、通常の開口部１８の縁を持って、開口部１８を広げて係合部２３の係合を解除しようとした場合、誤開封が防止される。具体的には、図８に示すように、雄側帯状基部２１Ａに設けられた屈曲部２１Ｃが折れ曲がるように広げられように、図８中の矢印で示す方向に引っ張り力が作用する。このため、開封のための引っ張り力は、雄側帯状基部２１Ａと雌側帯状基部２２Ａとの平面に沿って、雄側帯状基部２１Ａと雌側帯状基部２２Ａとを剪断させる方向に力が作用する。したがって、断面鉤形状の第一雄側爪２１Ｂ１および第一雌側爪２２Ｂ１と、第三雄側爪２１Ｄ１および第三雌側爪２２Ｄ１とが互いに噛み合う状態となる。このため、第一雄側爪２１Ｂ１および第一雌側爪２２Ｂ１と、第三雄側爪２１Ｄ１および第三雌側爪２２Ｄ１とが、それぞれ強く係合し合い、誤開封や改竄のための開封が防止される。
このように、化粧品や薬品など、あるいは細かい部品など、幼児や子供から遠ざけておきたい物などが誤開封されて取り出されてしまったり、改竄を目的として開封されてしまったりする誤開封を防止できる。 First, when the user first takes out the packaged object from the bag body 1 with the zipper tape, as shown in FIG. 8, the base films 11A and 11B are torn from the notch 17 to remove the top seal portion 14 side. By excising, the opening 18 is formed and opened.
Here, let's hold the edge of the normal opening 18 and widen the opening 18 to disengage the engaging portion 23 when the child opens the package for the purpose of interest or falsification. If so, erroneous opening is prevented. Specifically, as shown in FIG. 8, a pulling force acts in the direction indicated by the arrow in FIG. 8 so that the bent portion 21C provided on the male side band-shaped base portion 21A is expanded so as to bend. Therefore, the pulling force for opening acts in the direction of shearing the male-side strip-shaped base 21A and the female-side strip-shaped base 22A along the plane of the male-side strip-shaped base 21A and the female-side strip-shaped base 22A. .. Therefore, the first male-side claw 21B1 and the first female-side claw 22B1 having a hook-shaped cross section and the third male-side claw 21D1 and the third female-side claw 22D1 are in a state of meshing with each other. Therefore, the first male side claw 21B1 and the first female side claw 22B1 and the third male side claw 21D1 and the third female side claw 22D1 are strongly engaged with each other, and the opening for erroneous opening or falsification is performed. Be prevented.
In this way, it is possible to prevent accidental opening of cosmetics, chemicals, small parts, and other items that should be kept away from infants and children, such as being accidentally opened and taken out, or being opened for the purpose of falsification. ..

一方、袋本体１０に予め収納された被包装物Ｐの利用者が被包装物Ｐを取り出すため、あるいは、袋本体１０に被包装物Ｐを新たに収納するため、係合部２３の係合を解除する場合には、特異な開封方法が実施される。すなわち、屈曲部２１Ｃを有しない雌側帯状基部２２Ａがヒートシールされた袋本体１０の外面、具体的には雌側帯状基部２２Ａより収納空間１０Ｃ側の外面と、屈曲部２１Ｃを有する雄側帯状基部２１Ａがヒートシールされた袋本体１０の開口部１８の縁とを摘んで、袋本体１０を広げるように引っ張る。なお、摘む位置としては、例えば袋本体１０に印刷などにより示されていると、利用者は開封作業が容易となる。
この袋本体１０を広げる引っ張り力は、図９（Ａ）中の矢印に示すように作用し、第二雄側爪２１Ｂ２と第二雌側爪２２Ｂ２とが引っ掛かり合う状態となる。さらに、第三雄側爪２１Ｄ１および第三雌側爪２２Ｄ１は、引っ張り力が互いに離れる方向に作用する。この図９（Ａ）に示す状態では、第二雄側爪２１Ｂ２が断面山形状のため、引っ張り力は、第二雄側爪２１Ｂ２が第二雌側爪２２Ｂ２を乗り越えるように作用するとともに、第三雄側爪２１Ｄ１と第三雌側爪２２Ｄ１とが離れる状態となる。よって、比較的に小さい力で係合部２３の係合を解除できる。
そして、被包装物Ｐを取り出しあるいは収納した後は、再び雄部２１Ｂおよび雌部２２Ｂと、雄側鉤部２１Ｄおよび雌側鉤部２２Ｄとを、それぞれ係合させることで袋本体１０は再封止される。 On the other hand, in order for the user of the packaged object P previously stored in the bag body 10 to take out the packaged object P, or to newly store the packaged object P in the bag body 10, the engaging portion 23 is engaged. When releasing, a peculiar opening method is implemented. That is, the outer surface of the bag body 10 in which the female side strip-shaped base 22A having no bent portion 21C is heat-sealed, specifically, the outer surface on the storage space 10C side from the female-side strip-shaped base 22A, and the male side strip having the bent portion 21C. The base 21A picks up the edge of the opening 18 of the heat-sealed bag body 10 and pulls the bag body 10 so as to spread it. If the position to be picked is indicated by printing on the bag body 10, for example, the user can easily open the bag.
The pulling force that spreads the bag body 10 acts as shown by the arrow in FIG. 9A, and the second male side claw 21B2 and the second female side claw 22B2 are in a state of being caught. Further, the third male side claw 21D1 and the third female side claw 22D1 act in a direction in which the pulling forces are separated from each other. In the state shown in FIG. 9A, since the second male side claw 21B2 has a mountain shape in cross section, the pulling force acts so that the second male side claw 21B2 gets over the second female side claw 22B2, and the second male side claw 22B2. The third male side claw 21D1 and the third female side claw 22D1 are separated from each other. Therefore, the engagement of the engaging portion 23 can be disengaged with a relatively small force.
Then, after the packaged object P is taken out or stored, the bag body 10 is resealed by engaging the male portion 21B and the female portion 22B again with the male side hook portion 21D and the female side hook portion 22D, respectively. It will be stopped.

｛第二実施形態の効果｝
上述したように、上記第二実施形態では、ジッパーテープ２０を、係合部２３および係合鉤部２４にて複数条で係合する構成としている。
このため、第一実施形態の効果に加え、雄部材２１および雌部材２２の係合力がより高くなり、より誤開封を防止できる。 {Effect of the second embodiment}
As described above, in the second embodiment, the zipper tape 20 is configured to be engaged with a plurality of strips at the engaging portion 23 and the engaging hook portion 24.
Therefore, in addition to the effect of the first embodiment, the engaging force of the male member 21 and the female member 22 becomes higher, and erroneous opening can be further prevented.

また、上記第二実施形態では、係合鉤部２４として、雄側鉤部２１Ｄに収納空間側のみに突出する第三雄側爪２１Ｄ１を設けている。
このため、開封する際には、第三雄側爪２１Ｄ１と第三雌側爪２２Ｄ１とが離れる方向に開封のための引っ張り力が作用することとなる。したがって、誤開封防止のために係合力を増大させた構成でも、開封させる力が大きくなることを抑制しており、容易に開封できる。 Further, in the second embodiment, as the engaging hook portion 24, the male side hook portion 21D is provided with the third male side claw 21D1 protruding only on the storage space side.
Therefore, when opening the package, a pulling force for opening acts in the direction in which the third male side claw 21D1 and the third female side claw 22D1 are separated from each other. Therefore, even in a configuration in which the engaging force is increased to prevent erroneous opening, the force for opening is suppressed from being increased, and the opening can be easily performed.

［第三実施形態］
次に、本発明の第三実施形態を図面に基づいて説明する。
図１０には、第三実施形態におけるジッパーテープ付袋体の平面が示されている。図１１には、ジッパーテープ付袋体の断面が示されている。
この第三実施形態では、第一実施形態における袋本体１０の外面に把持部を設けたものである。 [Third Embodiment]

FIG. 10 shows the flat surface of the bag body with the zipper tape in the third embodiment. FIG. 11 shows a cross section of a bag with a zipper tape.
In this third embodiment, the grip portion is provided on the outer surface of the bag main body 10 in the first embodiment.

｛袋本体の構成｝
具体的には、袋本体１０の外面には、雌部材２２が配置される位置より収納空間１０Ｃ側、すなわちボトム側（図１０の下側）に位置して、基材フィルム１１Ｂがたぐり寄せられて舌片状に形成された把持部１６が設けられている。
把持部１６が設けられる位置は、基端にジッパーテープ２０が位置するような隣接する位置関係とするなど、ジッパーテープ２０の近傍が好ましい。
把持部１６の長手方向の両端部（図１の左右方向）は、サイドシール部１２でシールされ、把持部１６はボトムシール部１３側に向けて開放するポケット状に形成されている。 {Structure of bag body}
Specifically, on the outer surface of the bag body 10, the base film 11B is pulled toward the storage space 10C side, that is, the bottom side (lower side of FIG. 10) from the position where the female member 22 is arranged. A grip portion 16 formed in the shape of a tongue piece is provided.
The position where the grip portion 16 is provided is preferably in the vicinity of the zipper tape 20 such that the zipper tape 20 is located at the base end in an adjacent positional relationship.
Both ends of the grip portion 16 in the longitudinal direction (left-right direction in FIG. 1) are sealed by the side seal portion 12, and the grip portion 16 is formed in a pocket shape that opens toward the bottom seal portion 13 side.

｛ジッパーテープ付袋体の製造｝
次に、上記第三実施形態のジッパーテープ付袋体１を製造する動作として、被包装物Ｐを収納する前のジッパーテープ付袋を製造する動作について、図面を参照して説明する。なお、第一実施形態と同様の三方製袋の製造装置を用いて説明するが、ジッパーテープ付袋を製造するには、種々の方法を採用することができる。

Next, as an operation of manufacturing the bag body 1 with the zipper tape of the third embodiment, an operation of manufacturing the bag with the zipper tape before storing the packaged object P will be described with reference to the drawings. Although the description will be made using the same three-way bag manufacturing apparatus as in the first embodiment, various methods can be adopted for manufacturing the bag with the zipper tape.
FIG. 12 shows an explanatory diagram illustrating a state in which the grip portion is formed.
In FIG. 12, the left side of the drawing shows a plan view of the formation state of the grip portion, and the right side of the drawing shows a cross-sectional view at each stage in the plan view. Specifically, in FIG. 12, (A) is a situation where the film is sent out, (B) is a situation where the film is pulled together, (C) is a situation where the film is formed into a grip portion, and (D) a grip portion is formed. (E) is a situation in which the film is cut with a cutting blade, and (F) is a situation in which a pair of base films having a grip portion are cut out.

製造装置５は、いわゆる三方製袋機を基本構成とするもので、雄部材２１および雌部材２２を、基材フィルム１１Ａ、１１Ｂにそれぞれ接合し、ジッパーテープ付袋１Ａを製袋するものである。
製造装置５は、基材フィルム１１Ａ、１１Ｂを送り出すフィルム供給部５１と、雄部２１Ｂおよび雌部２２Ｂが係合されたジッパーテープ２０を送り出すテープ部材供給機構である一対のテープ供給部５２と、雄部材２１および雌部材２２を基材フィルム１１Ａ，１１Ｂにそれぞれヒートシールし、袋本体１０を製袋してジッパーテープ付袋１Ａを形成させる製袋部５４と、などを備えている。 The manufacturing apparatus 5 has a so-called three-way bag making machine as a basic configuration, and joins a male member 21 and a female member 22 to the base films 11A and 11B, respectively, to make a bag 1A with a zipper tape. ..
The manufacturing apparatus 5 includes a film supply unit 51 that feeds out the base films 11A and 11B, a pair of tape supply units 52 that are a tape member supply mechanism that feeds out the zipper tape 20 to which the male portion 21B and the female portion 22B are engaged. The male member 21 and the female member 22 are heat-sealed to the base films 11A and 11B, respectively, and a bag making portion 54 for making a bag main body 10 to form a bag 1A with a zipper tape is provided.

フィルム供給部５１には、図１２に示すような把持形成部５１Ｂが設けられている。把持形成部５１Ｂは、フィルム１１の長手方向の一側をたぐり寄せる対をなすローラ５１１と、たぐり寄せたフィルム１１を、所定の位置で所定の長さ寸法で折り返すように重ね合わせるガイドプレート５１２と、ガイドプレート５１２によりフィルム１１が部分的に折り返されて重ね合わされた部分を、例えばヒートシールして舌片状の把持部１６を形成するヒートシールバー５１３と、を備えている。なお、把持部１６の形成に際しては、ヒートシールに限らず、超音波による溶着、接着剤などを用いた接着など、各種方法を利用できる。
基材フィルム１１Ａ，１１Ｂの送り出しは、例えば連続的に一定速度で送り出す構成に限らず、間欠的に送り出す構成とするなど、いずれの送出方法を適用できる。 A film take-up roll 111 around which the film 11 is wound is detachably attached to the film supply unit 51, and the film 11 is cut into the base films 11A and 11B with a cutting blade 51A (see FIG. 12) to obtain a base. The material films 11A and 11B are sent out.
The film supply unit 51 is provided with a grip forming unit 51B as shown in FIG. 12. The grip forming portion 51B includes a pair of rollers 511 that pulls one side of the film 11 in the longitudinal direction, and a guide plate 512 that overlaps the pulled films 11 at a predetermined position so as to be folded back at a predetermined length. A heat seal bar 513 is provided, for example, by heat-sealing a portion of the film 11 partially folded back and overlapped by a guide plate 512 to form a tongue piece-shaped grip portion 16. In addition, in forming the grip portion 16, various methods such as welding by ultrasonic waves and adhesion using an adhesive can be used, not limited to heat sealing.
The base films 11A and 11B are not limited to a configuration in which they are continuously delivered at a constant speed, but any delivery method can be applied, such as a configuration in which they are intermittently delivered.

そして、ジッパーテープ付袋１Ａの製造に際しては、例えば三方製袋の製造装置５を用いて製造され、フィルム１１を供給するフィルム供給工程と、ジッパーテープ２０を供給するテープ供給工程と、雄部材２１と雌部材２２とを、基材フィルム１１Ａ，１１Ｂにそれぞれヒートシールする取付工程と、基材フィルム１１Ａ，１１Ｂからジッパーテープ付袋１Ａを形成させる製袋工程と、などを実施する。 Then, in manufacturing the bag 1A with the zipper tape, for example, a film supply step of supplying the film 11 and a tape supply step of supplying the zipper tape 20, which are manufactured by using the manufacturing apparatus 5 of the three-way bag making, and the male member 21 And the female member 22 are heat-sealed to the base films 11A and 11B, respectively, and a bag making step of forming a bag 1A with a zipper tape from the base films 11A and 11B is carried out.

まず、フィルム１１を巻回したフィルム巻取ロール１１１をフィルム供給部５１に装着しておく。
また、雌部材２２と、雄部材２１とを、それぞれ押出成形などによって成形しておく。そして、雌部材２２の雌部２２Ｂと、雄部材２１の雄部２１Ｂとが係合され、一体のジッパーテープ２０としてテープ巻取ロール５２１に巻回し、テープ巻取ロール５２１をテープ供給部５２に装着しておく。 First, the film take-up roll 111 around which the film 11 is wound is attached to the film supply unit 51.
Further, the female member 22 and the male member 21 are respectively molded by extrusion molding or the like. Then, the female portion 22B of the female member 22 and the male portion 21B of the male member 21 are engaged with each other and wound around the tape winding roll 521 as an integral zipper tape 20, and the tape winding roll 521 is attached to the tape supply unit 52. Put it on.

そして、フィルム供給工程では、フィルム巻取ロール１１１から供給されるフィルム１１に、把持形成部５１Ｂにより、把持部１６を形成させる把持形成工程を実施する。
具体的には、図１２（Ａ）の段階で供給されたフィルム１１は、図１２（Ｂ）の段階で把持形成部５１Ｂのローラ５１１により、所定位置でたぐり寄せて部分的に湾曲するように弛ませる。この後、図１２（Ｃ）の段階で、把持形成部５１Ｂのガイドプレート５１２により、弛ませた部分のフィルム１１を、所定の長さで部分的に折り返して重ね合わさるように成形する。そして、図１２（Ｄ）の段階で、フィルム１１の折り返して重ね合わさる部分を、把持形成部５１Ｂのヒートシールバー５１３でヒートシールし、舌片状の把持部１６を形成する。
この把持形成工程の後、図１２（Ｅ）の段階で示すように、切断刃５１Ａにより、フィルム１１の送り出し方向に対して、交差する方向で二等分するようにフィルム１１を切断する。この切断により、図１２（Ｆ）の段階で示すように、把持部１６をそれぞれ有した基材フィルム１１Ａ，１１Ｂが切り出され、下流側に送り出される。
この後、第一実施形態と同様に、テープ供給工程、取付工程および製袋工程が実施され、ジッパーテープ付袋１Ａが製造される。 Then, in the film supply step, a grip forming step is carried out in which the grip forming portion 16 is formed on the film 11 supplied from the film winding roll 111 by the grip forming portion 51B.
Specifically, the film 11 supplied at the stage of FIG. 12 (A) is pulled by the roller 511 of the grip forming portion 51B at the stage of FIG. 12 (B) so as to be pulled up at a predetermined position and partially curved. Loosen. After that, at the stage of FIG. 12C, the film 11 in the loosened portion is partially folded back to a predetermined length by the guide plate 512 of the grip forming portion 51B and formed so as to be overlapped with each other. Then, at the stage of FIG. 12D, the folded and overlapped portion of the film 11 is heat-sealed by the heat seal bar 513 of the grip forming portion 51B to form the tongue piece-shaped grip portion 16.
After this grip forming step, as shown in the stage of FIG. 12E, the film 11 is cut by the cutting blade 51A so as to bisect the film 11 in a direction intersecting the feeding direction of the film 11. By this cutting, as shown in the stage of FIG. 12F, the base films 11A and 11B having the grip portions 16 are cut out and sent out to the downstream side.
After that, the tape supply step, the attachment step, and the bag making step are carried out in the same manner as in the first embodiment, and the bag 1A with the zipper tape is manufactured.

｛ジッパーテープ付袋体の使用｝
次に、上記ジッパーテープ付袋体１の使用状況を説明する。
図１３には、開口された縁と袋本体の外面とを持って開封する際の開封状況を示す要部断面が示され、（Ａ）は開封力を作用させた状態、（Ｂ）は係合部の係合が解除された状態である。 {Use of bag with zipper tape}
Next, the usage status of the bag body 1 with the zipper tape will be described.
FIG. 13 shows a cross section of a main part showing an opening state when opening by holding an opened edge and an outer surface of a bag body, (A) is a state in which an opening force is applied, and (B) is engaged. The engagement of the joint is disengaged.

まず、使用者がジッパーテープ付袋体１から被包装物を最初に取り出すにあっては、図８に示すように、ノッチ１７から基材フィルム１１Ａ，１１Ｂを引き裂いて、トップシール部１４側を切除することで開口部１８が形成されて開封される。
ここで、子供が興味本位で開封したり、改竄目的などで開封したりする場合など、通常の開口部１８の縁を持って、開口部１８を広げて係合部２３の係合を解除しようとした場合、第一実施形態と同様に、誤開封が防止される。すなわち、開封のための引っ張り力は、雄側帯状基部２１Ａと雌側帯状基部２２Ａとの平面に沿って、雄側帯状基部２１Ａと雌側帯状基部２２Ａとを剪断させる方向に力が作用する。そして、断面鉤形状の第一雄側爪２１Ｂ１と第一雌側爪２２Ｂ１とが、互いに噛み合う状態となり、誤開封や改竄のための開封が防止される。 First, when the user first takes out the packaged object from the bag body 1 with the zipper tape, as shown in FIG. 8, the base films 11A and 11B are torn from the notch 17 to remove the top seal portion 14 side. By excising, the opening 18 is formed and opened.
Here, let's hold the edge of the normal opening 18 and widen the opening 18 to disengage the engaging portion 23 when the child opens the package for the purpose of interest or falsification. If so, erroneous opening is prevented as in the first embodiment. That is, the pulling force for opening acts in the direction of shearing the male-side strip-shaped base 21A and the female-side strip-shaped base 22A along the plane of the male-side strip-shaped base 21A and the female-side strip-shaped base 22A. Then, the first male-side claw 21B1 and the first female-side claw 22B1 having a hook-shaped cross section are in a state of meshing with each other, and opening for erroneous opening or falsification is prevented.

一方、袋本体１０に予め収納された被包装物Ｐの利用者が被包装物Ｐを取り出すため、あるいは、袋本体１０に被包装物Ｐを新たに収納するため、係合部２３の係合を解除する場合には、特異な開封方法が実施される。すなわち、袋本体１０の外面の把持部１６と、屈曲部２１Ｃを有する雄側帯状基部２１Ａがヒートシールされた袋本体１０の開口部１８の縁とを摘んで、袋本体１０を広げるように引っ張る。なお、摘む位置としては、例えば袋本体１０に印刷などにより示されていると、利用者は開封作業が容易となる。
この袋本体１０を広げる引っ張り力は、図１３（Ａ）中の矢印に示すように作用し、第二雄側爪２１Ｂ２と第二雌側爪２２Ｂ２とが引っ掛かり合う状態となる。この図１３（Ａ）に示す状態では、第二雄側爪２１Ｂ２が断面山形状のため、引っ張り力は第二雄側爪２１Ｂ２が第二雌側爪２２Ｂ２を乗り越えるように作用し、比較的に小さい力で係合部２３の係合を解除できる。
そして、被包装物Ｐを取り出しあるいは収納した後は、再び雄部２１Ｂおよび雌部２２Ｂを係合させることで、袋本体１０は再封止される。 On the other hand, in order for the user of the packaged object P previously stored in the bag body 10 to take out the packaged object P, or to newly store the packaged object P in the bag body 10, the engaging portion 23 is engaged. When releasing, a peculiar opening method is implemented. That is, the grip portion 16 on the outer surface of the bag body 10 and the edge of the opening 18 of the bag body 10 where the male side strip-shaped base portion 21A having the bent portion 21C is heat-sealed are picked and pulled so as to spread the bag body 10. .. If the position to be picked is indicated by printing on the bag body 10, for example, the user can easily open the bag.
The pulling force that spreads the bag body 10 acts as shown by the arrow in FIG. 13A, and the second male side claw 21B2 and the second female side claw 22B2 are in a state of being caught. In the state shown in FIG. 13 (A), since the second male side claw 21B2 has a mountain shape in cross section, the pulling force acts so that the second male side claw 21B2 gets over the second female side claw 22B2, and is relatively relatively. The engaging portion 23 can be disengaged with a small force.
Then, after the packaged object P is taken out or stored, the bag body 10 is resealed by engaging the male portion 21B and the female portion 22B again.

｛第三実施形態の効果｝
上述したように、上記第三実施形態では、屈曲部２１Ｃを有しない雌側帯状基部２２Ａが袋本体１０に取り付けられた位置に対して、収納空間１０Ｃ側に位置して把持部１６を設けている。
そして、開封に際しては、屈曲部２１Ｃを有した雄側帯状基部２１Ａがヒートシールされた袋本体１０の開口部１８の縁と、把持部１６とを持って袋本体１０を広げるように引っ張る。このことにより、係合部２３の係合を解除するように引っ張り力が作用することとなるので、係合部２３の係合が容易に解除できる。したがって、第一実施形態の効果に加え、把持部１６を持って引っ張る簡単な作業で、容易に開封できる。 {Effect of the third embodiment}
As described above, in the third embodiment, the grip portion 16 is provided located on the storage space 10C side with respect to the position where the female side band-shaped base portion 22A having no bent portion 21C is attached to the bag body 10. There is.
Then, at the time of opening, the male side strip-shaped base portion 21A having the bent portion 21C is pulled so as to spread the bag main body 10 by holding the edge of the opening 18 of the bag main body 10 heat-sealed and the grip portion 16. As a result, a pulling force acts so as to disengage the engaging portion 23, so that the engaging portion 23 can be easily disengaged. Therefore, in addition to the effect of the first embodiment, the package can be easily opened by a simple operation of holding and pulling the grip portion 16.
