Description

本発明は、雄型ファスナー部および雌型ファスナー部を有するチャックテープが設けられたチャックテープ付き袋およびその製造方法に関する。   The present invention relates to a bag with a chuck tape provided with a chuck tape having a male fastener portion and a female fastener portion, and a manufacturing method thereof.

食料品、医薬品、電子部品、事務用品などの各種物品を密封包装するための包装材として、チャックテープを備えた袋（チャックテープ付き袋）が広く使用されている。このようなチャックテープ付き袋は、例えば、包材を重ね合わせ、その周縁部をヒートシールして形成した袋において、この袋体の開口縁に沿って、一方の包材の内面に雄型ファスナー部をヒートシールし、他方の包材の内面に雌型ファスナー部をヒートシールした構成のものが知られている。
このようなチャックテープ付き袋として、チャックテープの開閉を容易とするために把手を設けた構成が知られている（例えば、特許文献１参照）。 As a packaging material for hermetically wrapping various items such as foods, pharmaceuticals, electronic parts, and office supplies, bags equipped with a chuck tape (bags with a chuck tape) are widely used. Such a bag with a zipper tape is, for example, a bag formed by stacking packaging materials and heat-sealing the peripheral portion thereof, and a male fastener on the inner surface of one packaging material along the opening edge of the bag body. There is known a configuration in which a part is heat-sealed and a female fastener part is heat-sealed on the inner surface of the other packaging material.
As such a bag with a chuck tape, a configuration in which a handle is provided to facilitate opening and closing of the chuck tape is known (see, for example, Patent Document 1).

この特許文献１に記載のものは、袋上部に開口する注ぎ口の下方にチャックテープを設けるとともに、チャックテープの上方から注ぎ口の外方に延びるチャックテープの開放片を設けている。そして、開放片を摘んで左右に引っ張ることで、互いに噛み合っているチャックテープを開く構成が採られている。   In the device described in Patent Document 1, a chuck tape is provided below the spout opening at the top of the bag, and an open piece of the chuck tape extending from the top of the chuck tape to the outside of the spout is provided. And the structure which opens the chuck tape which has mutually engaged by picking an open piece and pulling it right and left is taken.

特開２００２−３３７８９１号公報JP 2002-337891 A

しかしながら、上記特許文献１に記載のような開放片を備えた従来のチャックテープ付き袋では、チャックテープを開くための構成が、先端部が自由端となる舌片状に突出する形状で利用者が摘んで左右に引っ張るので、例えば調理作業中などで利用者の手が濡れていたり油などが付着していたりする場合では、開放片を摘んで左右に引っ張る際に滑ってしまい、直ちに開封することが困難となる。そこで、調理作業中に手を拭いたり洗ったりして滑らないようにする動作が必要となり、開封作業が煩わしく、調理作業などの主の作業に影響を及ぼすおそれがある。
また、開封作業時に一部が開封する状態で片方の開放片から滑って手が離れ、その際の衝撃などにより収容物が一部こぼれ出たり、両方の開放片から手が離れて落としてしまい、内容物がこぼれ出たりするおそれもある。 However, in the conventional bag with a chuck tape provided with an open piece as described in Patent Document 1, the structure for opening the chuck tape has a shape in which the tip portion protrudes into a tongue piece shape having a free end. For example, if the user's hand is wet or oil is attached during cooking work, it will slip when picking the open piece and pulling it left and right, and open immediately. It becomes difficult. Therefore, an operation for wiping or washing hands during cooking to prevent slipping is necessary, and the opening operation is troublesome, which may affect main operations such as cooking.
In addition, when the opening operation is partially opened, the hand slips from one of the open pieces, and a part of the contents spills due to an impact at that time, or the hands are separated from both open pieces and dropped. The contents may spill out.

本発明の目的は、このような点に鑑みて、開封が容易で使い勝手のよいチャックテープ付き袋およびその製造方法を提供する。   In view of the above, an object of the present invention is to provide a bag with a zipper tape that is easy to open and easy to use, and a method for manufacturing the same.

〔チャックテープ付き袋の動作〕
次に、上記チャックテープ付き袋１００の動作について、チャックテープ付き袋１００を製造する製造工程と、チャックテープ付き袋１００の開封作業とを図面を参照して説明する。
図３は、チャックテープ付き袋１００を製造する動作を示す概念斜視図である。 [Operation of bag with chuck tape]
Next, regarding the operation of the bag 100 with a chuck tape, a manufacturing process for manufacturing the bag 100 with a chuck tape and an opening operation of the bag 100 with a chuck tape will be described with reference to the drawings.
FIG. 3 is a conceptual perspective view showing an operation of manufacturing the bag 100 with a chuck tape.

（チャックテープ付き袋の製造動作）
まず、チャックテープ付き袋１００を製造する動作を説明する。
チャックテープ付き袋１００の製造に利用される図示しない製袋装置は、図示しない前処理部と、図３に示すような折返片形成部５００と、図示しない溶断部と、袋搬送部と、などを備えている。
前処理部としては、包材送出部と、包材折返部と、テープ送出部と、テープ貼付部と、などを備えている。包材送出部は、例えばロール状の包材シート２２０の一端を巻き戻すように順次送り出して搬送する。包材折返部は、包材送出部にて送り出されて搬送される包材シート２２０を搬送方向の一縁側を他縁側に重ね合わせるように搬送方向の略中央で折り返す。テープ送出部は、あらかじめ雄型ファスナー部および雌型ファスナー部が嵌合されたロール状のチャックテープ３００の一端を巻き戻すように順次送り出し、包材折返部により折り返される包材シート２２０の重なり合う包材２１０間に位置させて搬送させる。テープ貼付部は、テープ送出部にて送り出されたチャックテープ３００を包材２１０にそれぞれ接着させる。
折返片形成部５００は、図３に示すように、軸方向が略平行で外周面が互いに接触する状態に、前処理部から搬送される包材シート２２０の搬送方向に対して軸方向が交差する状態に配設された一対の折返ローラ５１０を備えている。これら折返ローラ５１０は、前処理部で包材２１０が重ね合わされチャックテープ３００が取り付けられて搬送される包材シート２２０の互いに重なり合う縁を狭持し、搬送方向に対して反対方向に回転することで、包材２１０の一縁側を包材２１０の対向方向に対して反対側となる外側へ折り返して折返片４１０を形成する。また、折返片形成部５００は、図３に示すように、軸方向が略平行で外周面が互いに接触する状態に軸方向が包材シート２２０の搬送方向に対して略直行する状態に配設された一対の癖付ローラ５２０を備えている。これら癖付ローラ５２０は、搬送方向に対して順回転方向で回転させて搬送される包材シート２２０を挟み込み、折返ローラにて折り返される折返片４１０が折返し状態を維持するように転圧する。
溶断部は、折返片形成部５００で折返片４１０が形成されて搬送される包材シート２２０を、包材シート２２０の搬送方向に対して所定間隔、すなわちチャックテープ付き袋１００の幅方向の寸法に対応した間隔で熱溶着および溶断してチャックテープ付き袋１００を形成する。この溶断部は、搬送される包材シート２２０を、搬送方向に対して略直行する方向に沿った帯状に熱溶着してサイドシール部２０３を形成する図示しないヒート部と、このヒート部で熱溶着した帯状の部分の略中央で溶断する図示しないカット部と、を備えている。
袋搬送部は、溶断部で形成されたチャックテープ付き袋１００を、別途検品や梱包工程へ適宜搬送する。 (Manufacturing operation of bag with chuck tape)
First, an operation for manufacturing the bag 100 with the chuck tape will be described.
A bag making apparatus (not shown) used for manufacturing the bag 100 with the chuck tape includes a pre-processing unit (not shown), a folded piece forming unit 500 as shown in FIG. 3, a fusing unit (not shown), a bag conveying unit, and the like. It has.
As a pre-processing part, a packaging material sending part, a packaging material folding | turning part, a tape sending part, a tape sticking part, etc. are provided. The packaging material delivery unit sequentially feeds and conveys one end of the roll-shaped packaging material sheet 220, for example. The packaging material folding unit folds the packaging material sheet 220 fed and conveyed by the packaging material delivery unit at approximately the center in the conveyance direction so that one edge side of the conveyance direction overlaps the other edge side. The tape delivery unit sequentially feeds one end of the roll-shaped chuck tape 300 in which the male fastener portion and the female fastener portion are fitted in advance so as to rewind, and the packaging material sheet 220 folded by the packaging material folding portion overlaps. It is located between the materials 210 and conveyed. The tape applying unit adheres the chuck tape 300 sent out by the tape sending unit to the packaging material 210, respectively.
As shown in FIG. 3, the folded piece forming unit 500 has an axial direction that is substantially parallel to the conveyance direction of the packaging material sheet 220 conveyed from the pretreatment unit in a state where the axial directions are substantially parallel and the outer peripheral surfaces are in contact with each other. A pair of folding rollers 510 disposed in a state of being provided. These folding rollers 510 hold the overlapping edges of the packaging material sheet 220 that is transported with the packaging material 210 overlapped and the chuck tape 300 attached thereto in the pretreatment section, and rotate in the direction opposite to the transportation direction. Thus, the folded piece 410 is formed by folding one edge side of the packaging material 210 to the outside which is the opposite side to the facing direction of the packaging material 210. Further, as shown in FIG. 3, the folded piece forming unit 500 is disposed in a state in which the axial direction is substantially parallel and the outer peripheral surfaces are in contact with each other, and the axial direction is substantially perpendicular to the conveying direction of the packaging sheet 220. A pair of flanged rollers 520 is provided. These flanged rollers 520 sandwich the packaging material sheet 220 that is rotated and rotated in the forward rotation direction with respect to the conveying direction, and rolls the folded pieces 410 folded by the folding rollers so as to maintain the folded state.
The fusing part has a predetermined interval with respect to the conveying direction of the packaging material sheet 220, that is, the dimension in the width direction of the bag 100 with the chuck tape. The bag 100 with the chuck tape is formed by heat welding and cutting at intervals corresponding to the above. The fusing unit includes a heating part (not shown) that heat-welds the conveyed packaging sheet 220 in a band shape along a direction substantially perpendicular to the conveying direction, and forms a side seal part 203. And a cut portion (not shown) that melts at approximately the center of the welded belt-like portion.
A bag conveyance part conveys suitably the bag 100 with a chuck tape formed in the fusing part to an inspection or a packaging process separately.

そして、チャックテープ付き袋１００の製造に際しては、前処理部により、包材シート２２０を搬送しつつ搬送方向の一縁側を他縁側に折り返して包材２１０が重なり合う状態とするとともに、チャックテープ３００を包材２１０の対向する内側で縁近傍に接着する前処理工程を実施する。
この前処理工程で折り返されてチャックテープ３００が接着された包材シート２２０を、図３に示すように、折返片形成部５００により、各包材２１０の一縁側をそれぞれ対向方向に対して外側へ折り返して折返片４１０を形成する折返片形成工程を実施する。
この折返し片形成工程で折返片４１０が形成されて搬送される包材シート２２０を、溶断部により、搬送方向に対してチャックテープ付き袋１００の幅寸法に対応する間隔で、包材２１０同士および包材２１０と折返片４１０とをヒート部で熱溶着するとともに、熱溶着した部分をカット部で溶断し、チャックテープ付き袋１００を製造する。この製造されたチャックテープ付き袋１００は、袋搬送部により適宜後工程へ搬送され、検品されたり適宜まとめて包装されたりする。 Then, when manufacturing the bag 100 with the chuck tape, the pre-processing unit folds one edge side in the conveying direction to the other edge side while conveying the packaging material sheet 220 so that the packaging material 210 overlaps, and the chuck tape 300 is A pre-processing step of adhering to the vicinity of the edge on the inside facing the packaging material 210 is performed.
As shown in FIG. 3, the folded sheet forming unit 500 wraps one edge side of each packaging material 210 outward with respect to the opposing direction, as shown in FIG. 3. A folded piece forming step of folding back to form the folded piece 410 is performed.
In the folded piece forming step, the packaging material sheet 220 that is conveyed with the folded piece 410 formed is conveyed by the fusing part at intervals corresponding to the width dimension of the bag 100 with the chuck tape with respect to the conveying direction. The packaging material 210 and the folded piece 410 are thermally welded at the heat portion, and the thermally welded portion is melted at the cut portion to manufacture the bag 100 with the chuck tape. The manufactured bag 100 with a chuck tape is appropriately transported to a subsequent process by the bag transporting unit, and is inspected or appropriately packaged.

（チャックテープ付き袋の開封動作）
次に、チャックテープ付き袋１００の開封作業について説明する。
チャックテープ付き袋１００の開封に際しては、図２に示すように、利用者が指Ｆを把手部４００の操作口４０１から作業空間４０２内に挿入する。そして、投入孔２０１の開口縁側となる把手部４００の底部分を互いに反対方向に指先側から広げるようにして、投入孔２０１の開口縁部分を開くように一対の包材２１０を互いに離間する方向へ引っ張り力を作用させる。すなわち、指先に把手部４００の折返片４１０を引っ掛けるようにして広げる。この包材２１０を互いに離間する方向へ引っ張り力を作用させることで、互いに嵌合するチャックテープ３００の嵌合凹部３１２および嵌合凸部３２２の嵌合が解除され、収容空間２０２が投入孔２０１を介して外部に連通する開封状態となる。
この際、例えば人差し指および中指を作業空間４０２内に挿入し親指を把手部４００の折返片４１０の外面側に添えて折返片４１０を摘むようにすると、より引っ張り力を作用させ易い。また、把手部４００の略中央で摘むようにして広げると、引っ張り力がチャックテープ３００に効率よく作用し、開封しやすくなる。
また、封止の際には、従来のチャックテープ３００の封止作業と同様に、包材２１０の外面側をチャックテープ３００の位置で摘んで扱くようにすればよい。 (Opening of the bag with zipper tape)
Next, the opening operation | work of the bag 100 with a chuck tape is demonstrated.
When opening the bag 100 with the chuck tape, as shown in FIG. 2, the user inserts the finger F into the work space 402 from the operation port 401 of the handle 400. A direction in which the bottom portion of the grip portion 400 on the opening edge side of the charging hole 201 is widened in the opposite direction from the fingertip side and the pair of packaging materials 210 are separated from each other so as to open the opening edge portion of the charging hole 201. Apply a pulling force to That is, the folded piece 410 of the handle 400 is hooked on the fingertip and spreads. By applying a pulling force to the packaging material 210 in a direction away from each other, the fitting recess 312 and the fitting projection 322 of the chuck tape 300 fitted to each other are released, and the accommodation space 202 is inserted into the insertion hole 201. It will be in the open state which communicates with the exterior via.
At this time, for example, if the index finger and the middle finger are inserted into the work space 402 and the thumb is attached to the outer surface side of the folded piece 410 of the handle portion 400, the folded piece 410 is picked up more easily. Further, if the grip part 400 is spread out so as to be picked at the approximate center, the pulling force acts on the chuck tape 300 efficiently, and the opening becomes easy.
Further, at the time of sealing, the outer surface side of the packaging material 210 may be picked and handled at the position of the chuck tape 300 as in the conventional sealing operation of the chuck tape 300.

〔実施の形態の作用効果〕
上述したチャックテープ付き袋１００によれば、重ね合わされて一部に投入孔２０１を開口する状態に周縁を熱溶着して袋体２００を構成する包材２１０の投入孔２０１の開口縁に、包材２１０の外面との間に投入孔２０１が開口する方向に対して略反対方向に向けて操作口４０１を開口する作業空間４０２を区画する把手部４００を、それぞれ連設している。
このことにより、開封時には、各把手部４００の操作口４０１から作業空間４０２内に例えば指Ｆを挿入して把手部４００を互いに離間する方向に引っ張って投入孔２０１の開口縁を開く状態に引っ張り力を作用させることで、チャックテープ３００の互いの嵌合が解除される。このため、把手部４００に利用者が指Ｆを引っ掛けるようにして投入孔２０１の開口縁を開くように引っ張り力を作用させて開封するので、仮に指Ｆが濡れていたり油などが付着していたりしても、滑ることなく把手部４００に開口縁を開くように引っ張り力を作用させることが容易にでき、容易に開封でき、滑り落とすなどの不都合もなく、使い勝手を向上できる。 [Effects of Embodiment]
According to the above-described bag 100 with the chuck tape, the wrapping is performed on the opening edge of the charging hole 201 of the packaging material 210 constituting the bag body 200 by heat-welding the peripheral edge so that the charging hole 201 is partially opened. A grip portion 400 that divides a work space 402 that opens the operation port 401 in a direction substantially opposite to the direction in which the insertion hole 201 opens is connected to the outer surface of the material 210.
As a result, at the time of opening, for example, a finger F is inserted into the work space 402 from the operation port 401 of each handle part 400 and the handle part 400 is pulled away from each other to pull the opening edge of the insertion hole 201 open. By applying a force, the mutual engagement of the chuck tapes 300 is released. For this reason, since the opening is made by applying a pulling force so that the user hooks the finger F on the handle 400 and opens the opening edge of the insertion hole 201, the finger F is wet or oil is attached. In this case, it is possible to easily apply a pulling force so as to open the opening edge of the handle portion 400 without slipping, so that it can be easily opened, and there is no inconvenience such as sliding off, and the usability can be improved.

そして、作業空間４０２内に利用者の指Ｆが挿入可能に操作口４０１を開口する袋状に把手部４００を形成している。
このため、袋体２００の投入孔２０１の開口縁側が袋状の把手部４００の底部分となるので、把手部４００の底部分を互いに反対方向に押し広げるように投入孔２０１の開口縁を開くように引っ張り力を作用させることで、確実に滑ることなく把手部４００に引っ張り力を効率よく作用させることができる。さらに、投入孔２０１の開口縁側が把手部４００の底部分となるので、利用者の指Ｆを作業空間４０２内に挿入した状態では投入孔２０１の開口縁に対して指Ｆが覆われる状態となり、袋体２００内の収容空間２０２に収容する収容物が利用者の指Ｆに付着するなどの不都合も防止できる。
そして、指Ｆが挿入できる程度、例えば幅寸法が２ｃｍ程度の袋状に把手部４００を形成している。このため、指Ｆを引っ掛けるようにして引っ張り力を嵌合するチャックテープ３００の離間方向へ作用させることが、最小限の構成で得られる。
さらには、把手部４００が袋状で、通常時は包材２１０の外面に積層する状態となっていることから、嵩張ることなく一般的な袋と同様に収納・管理でき、より使い勝手がよい。 And the handle part 400 is formed in the bag shape which opens the operation port 401 so that a user's finger | toe F can be inserted in the work space 402. FIG.
For this reason, since the opening edge side of the charging hole 201 of the bag body 200 becomes the bottom part of the bag-like handle part 400, the opening edge of the charging hole 201 is opened so as to push the bottom part of the handle part 400 in the opposite directions. By applying the pulling force as described above, the pulling force can be efficiently applied to the grip portion 400 without slipping reliably. Furthermore, since the opening edge side of the insertion hole 201 is the bottom portion of the handle portion 400, the finger F is covered with the opening edge of the insertion hole 201 when the user's finger F is inserted into the work space 402. In addition, it is possible to prevent inconveniences such as an object to be accommodated in the accommodation space 202 in the bag body 200 adhering to the user's finger F.
And the handle part 400 is formed in the bag shape which can insert the finger F, for example, a width dimension is about 2 cm. For this reason, it is possible to apply the pulling force in the separating direction of the chuck tape 300 by hooking the finger F with the minimum configuration.
Furthermore, since the handle portion 400 is in a bag shape and is normally laminated on the outer surface of the packaging material 210, it can be stored and managed in the same manner as a general bag without being bulky, and is more convenient.

さらに、包材２１０の投入孔２０１の開口縁に対応する一縁側を外面側に折り返して把手部４００を包材２１０に一連に設けている。
このため、互いに重ね合わされる包材２１０を単にそれぞれの開口縁側を折り返す簡単な製造工程で、滑ることなく容易に開封できる把手部４００を形成でき、製造性を向上できる。さらに、折り返すことで把手部４００を開封作業時に開口縁に対して指Ｆが覆われる状態となる袋状に形成することが容易にできる。したがって、指先で把手部４００を広げるように引っ張り力を作用させることができるとともに指Ｆに収容物が付着する不都合の防止が容易にできる構成が容易に得られる。 Furthermore, a grip portion 400 is provided in series on the packaging material 210 by folding one edge side corresponding to the opening edge of the charging hole 201 of the packaging material 210 to the outer surface side.
For this reason, the grip part 400 which can be easily opened without slipping can be formed by a simple manufacturing process in which the packaging materials 210 overlapped with each other are simply folded back at the respective opening edge sides, and the productivity can be improved. Furthermore, the handle 400 can be easily formed into a bag shape in which the finger F is covered with respect to the opening edge during the opening operation by folding back. Therefore, it is possible to easily obtain a configuration in which a pulling force can be applied so as to spread the handle portion 400 with the fingertips, and the inconvenience of the attached matter to the finger F can be easily prevented.

また、包材２１０の熱溶着により形成されるサイドシール部２０３の形成時に、投入孔２０１が開口する方向に対して把手部４００の両側をサイドシール部２０３の形成時にサイドシール部２０３とともに熱溶着させて作業空間４０２を区画する状態に把手部４００を形成している。
このため、重なり合う包材２１０の周縁を熱溶着にて貼り合わせて袋体２００を形成する動作で把手部４００も合わせて形成でき、袋体２００を形成する一動作で把手部４００も形成できることから製造性を向上できる。
そして、図３に示すような折返片４１０を形成する対をなすローラを設ける簡単な構造の折返片形成部５００を従来の製袋装置に組み付ける程度で把手部４００を有したチャックテープ付き袋１００を、従来の袋体を製袋するのと同様に連続して効率よく製造できる。 Further, when forming the side seal portion 203 formed by thermal welding of the packaging material 210, both sides of the handle portion 400 are thermally welded together with the side seal portion 203 when forming the side seal portion 203 with respect to the direction in which the insertion hole 201 opens. Thus, the handle portion 400 is formed so as to partition the work space 402.
For this reason, it is possible to form the handle portion 400 by the operation of forming the bag body 200 by bonding the peripheral edges of the overlapping packaging material 210 by heat welding, and the handle portion 400 can also be formed by one operation of forming the bag body 200. Manufacturability can be improved.

このことにより、投入孔２０１の開口縁に連設した把手部４００を持って開口縁を開くように作用させる引っ張り力がチャックテープ３００の雌取付基材３１１および雄取付基材３２１に互いに離間する方向に効率よく作用させることができ、良好な開封作業が容易に得られる。特に、数ｍｍ〜２，３ｃｍ程度であれば、把手部４００の位置とチャックテープ３００との位置が比較的に近く、良好な開封作業が容易に得られる。 Further, the strip-shaped female attachment base material 311 of the female fastener portion 310 and the strip-shaped male attachment base material 321 of the male fastener portion 320 are opened along the opening edge of the insertion hole 201 at one edge located on the opening edge side. A predetermined distance range from the edge, for example, several mm to several cm, is attached to the packaging material 210 by surface bonding.
As a result, the pulling force that acts to open the opening edge with the grip portion 400 provided continuously with the opening edge of the insertion hole 201 is separated from the female mounting base material 311 and the male mounting base material 321 of the chuck tape 300. It can be made to act efficiently in the direction, and a good opening operation can be easily obtained. In particular, when the thickness is about several mm to a few cm, the position of the grip portion 400 and the position of the chuck tape 300 are relatively close, and a good opening operation can be easily obtained.
