Description
本発明は、パウチ容器の周縁に溶着して用いられるスパウトに関するものであって、より詳しくは、パウチ容器の周縁に、先にスパウトの片面だけを溶着した状態で、未溶着側からパウチ内への内容物の充填を可能にし、その後でパウチ容器とスパウトを密封状態で溶着することにより、スパウトをパウチ容器の周縁の任意の部位に付設しても内容物の充填作業において邪魔にならないスパウトに関する。 The present invention relates to a spout for use by welding to the periphery of the pouch container, more specifically, the periphery of the pouch container, while welding only one side of the previously spout, the unwelded side into the pouch The pouch container and the spout are then sealed and welded in a sealed state so that the spout can be attached to any part of the periphery of the pouch container without disturbing the contents filling operation. .
従来技術の一例を示す図11において、パウチ50の周縁に溶着され、上端が閉塞部51で閉塞されてその閉塞部51を引き裂くことで開封する、所謂ワンピースタイプのスパウト52は、その口部から内容物を充填することが出来ないため、パウチ50の上部を斜めにカットし、その斜めカット部53に上記のスパウト52を溶着することで、パウチ50の上部に内容物を充填する開口部分54を確保して、その開口部分54からパウチ50に内容物を矢印A方向から充填した後、その開口部分54を溶着して閉じることになる(特許文献1参照)。 In FIG. 11 showing an example of the prior art, a so-called one-piece type spout 52 that is welded to the periphery of the pouch 50 and is opened by tearing the closed portion 51 with its upper end closed by the closed portion 51 is opened from its mouth. Since the contents cannot be filled, the upper portion of the pouch 50 is cut obliquely, and the spout 52 is welded to the oblique cut portion 53 so that the opening portion 54 is filled with the contents on the upper portion of the pouch 50. Is secured from the opening portion 54 to the pouch 50 from the direction of arrow A, and then the opening portion 54 is welded and closed (see Patent Document 1).
あるいは、図12に示すように、パウチ50の上部中央にワンピースタイプのスパウト52Aを溶着し、パウチ50の底部55は溶着しない状態にしておき、パウチ50に内容物を充填する際、スパウト52Aを下方に向けて、パウチ50の底部55から内容物を矢印B方向から充填した後、その底部55を溶着して閉じることになる。 Alternatively, as shown in FIG. 12, a one-piece type spout 52A is welded to the upper center of the pouch 50, and the bottom 55 of the pouch 50 is not welded, and when the pouch 50 is filled with the contents, the spout 52A is After filling the contents from the bottom 55 of the pouch 50 in the arrow B direction downward, the bottom 55 is welded and closed.
図11のものは、パウチ50の上部にある開口部分54から内容物を充填することが出来るが、スパウト52がパウチ50の斜めカット部53に溶着してあるため、スパウト52が出っ張り部分となって、輸送や保管に悪影響を及ぼしたり、パウチ50の有効充填量が減るなどの虞がある。また、スパウトをパウチの上方中央部に溶着することが出来ないという不都合がある。 Although the thing of FIG. 11 can be filled with the content from the opening part 54 in the upper part of the pouch 50, since the spout 52 is welded to the diagonal cut part 53 of the pouch 50, the spout 52 becomes a protruding part. This may adversely affect transportation and storage, and may reduce the effective filling amount of the pouch 50. In addition, there is an inconvenience that the spout cannot be welded to the upper center portion of the pouch.
また、図12のものは、予めスパウト52Aが溶着されたパウチ50の底部55から内容物を充填した後、その底部55を溶着して閉じるため、スパウトをパウチの中央部に溶着することが出来るが、パウチに自立性を持たせたい場合、スタンディングタイプとなるように底部55を閉じるのが極めて困難であり、事実上適用することが出来ない。
かかる従来技術の問題点に鑑みて、パウチ50の上部をすべて溶着しないで開口部分を残しておき、パウチ50に内容物を充填した後に、その開口部分にパウチ50を溶着することも考えられる。すなわち、パウチ50の上部中央に予めワンピースタイプのスパウト52を溶着してあるのに、パウチ50の上部から内容物を充填することが出来る、スパウトが望まれていた。
Further, in FIG. 12, since the contents are filled from the bottom 55 of the pouch 50 to which the spout 52A is previously welded, and the bottom 55 is welded and closed, the spout can be welded to the center of the pouch. However, it is extremely difficult to close the bottom 55 so as to be a standing type when the pouch is desired to be self-supporting, and it cannot be applied practically.
In view of the problems of the prior art, it is conceivable to leave the opening portion without welding the entire upper portion of the pouch 50 and fill the pouch 50 with the contents, and then weld the pouch 50 to the opening portion. That is, although a one-piece type spout 52 is previously welded to the upper center of the pouch 50, a spout that can be filled with contents from the upper portion of the pouch 50 has been desired.
そこで、本発明の目的は、パウチ容器の周縁にスパウトの片面だけを先に溶着した状態で未溶着側から内容物の充填を可能にし、内容物充填後に、未溶着側を溶着することにより、その結果、スパウトをパウチ容器の周縁の任意の部位に付設しても内容物の充填作業において邪魔にならないスパウトを提供することにある。
また、本発明の他の目的は、上記スパウトを付設したスパウト付きパウチ容器及びスパウト付包装体を提供することにある。
さらに、本発明の他の目的は、上記スパウト付包装体の製造方法を提供することにある。
Therefore, the object of the present invention is to enable filling of the contents from the unwelded side in the state where only one side of the spout is welded to the peripheral edge of the pouch container first, and by welding the unwelded side after filling the contents, As a result, it is an object of the present invention to provide a spout that does not get in the way of filling the contents even if the spout is attached to any part of the periphery of the pouch container.

There is a unique effect that has become possible.
以下に、図面を参照して本発明を実施するための形態を説明する。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
図1および図4に示す通り、スパウト1は、2枚のプラスチックフィルム2及び3の周縁2a及び3aを溶着し、内部に内容物を収納するパウチ容器4のスパウト溶着側周縁2b及び3bに溶着して用いられる、上端が閉塞部5により閉塞されたものであって、このスパウト1の下部外周面には、横方向に延びる複数の溶着用リブ6が形成されており、溶着用リブ6は、パウチ容器4を構成する一のプラスチックフィルム2の側、すなわち、周縁2bに溶着される第一溶着用リブ7、パウチ容器4を構成する他のプラスチックフィルム3の側、すなわち、周縁3bに溶着される第二溶着用リブ8とで構成され、この第一溶着用リブ7と第二溶着用リブ8の縦方向断面形状の断面積が同一であり、且つ、外方へ突出する第一溶着用リブ7の頂部の高さ(H1)は、第二溶着用リブ8の頂部の高さ(H2)より高く(H1>H2)形成されているものである。よって言うまでもなく、第一溶着用リブ7の幅(W1)は、第二溶着用リブ8の幅(W2)より狭く形成されている。 As shown in FIGS. 1 and 4 , the spout 1 welds the peripheral edges 2a and 3a of the two plastic films 2 and 3, and welds the spout welding side peripheral edges 2b and 3b of the pouch container 4 containing the contents therein. The upper end of the spout 1 is closed, and a plurality of welding ribs 6 extending in the lateral direction are formed on the outer peripheral surface of the spout 1. The first welding rib 7 that is welded to the side of one plastic film 2 constituting the pouch container 4, that is, the peripheral edge 2b, and the side of the other plastic film 3 that constitutes the pouch container 4, ie, the peripheral edge 3b. The first welding rib 8 and the first welding rib 7 and the second welding rib 8 have the same cross-sectional area in the longitudinal cross-sectional shape and project outward. the top of the use rib 7 Height (H1) is one that is higher than (H1> H2) formed height of the top portion of the second weld ribs 8 (H2). Therefore, it goes without saying that the width (W1) of the first welding rib 7 is narrower than the width (W2) of the second welding rib 8.
前記パウチ容器4は、2枚のプラスチックフィルム2及び3の上縁を除く周縁2a及び3aを溶着して袋状にし、内容物を収納できるようにして、パウチ容器4の開口している部分の周縁2b及び3bに、スパウト1の下部を溶着してなるものである。そして、パウチ容器4は、その下部が少なくとも内部に内容物が収納された状態で、スタンディングポーズをとることが出来るように形成されている、いわゆるスタンディングパウチと呼ばれる形態で形成されている。すなわち、後に詳述するように、パウチ容器4の内部に内容物を収納する際、パウチ4の底部から充填する必要がないため、パウチ容器4の底部の形状をいかようにも加工できるからである。 The pouch container 4 is formed by welding the peripheral edges 2a and 3a excluding the upper edges of the two plastic films 2 and 3 into a bag shape so that the contents can be stored. The lower part of the spout 1 is welded to the peripheral edges 2b and 3b. And the pouch container 4 is formed in a so-called standing pouch form so that a lower portion of the pouch container 4 can take a standing pose in a state where contents are stored at least inside. That is, as will be described in detail later, when the contents are stored in the inside of the pouch container 4, it is not necessary to fill from the bottom of the pouch 4, so that the shape of the bottom of the pouch container 4 can be processed in any way. is there.
図2、3に示す通り、前記スパウト1は、上端が閉塞部5によって閉塞される中空の注出筒形状を有しており、その下部がパウチ溶着部となっている。また、スパウト1は、図2、3の縦断面形状からもわかるように扁平形であり、横断面形状で略楕円形状を有している。
前記スパウト1の閉塞部5は、破断可能な弱化部10を介してスパウト1の注出筒上端に接続した引き剥がし部11であり、その一部に開口用つまみ部12が設けられ、さらに、この開口用つまみ部12には、手指の入る孔12aが設けられている。したがって、開口用つまみ部12の孔12aに手指を差し込み、引き剥がし方向に力を加え弱化部10を破砕して、引き剥がし部11を除去することで、閉塞部5を開口することができる。その結果、パウチ容器4の密封性が保持され、且つパウチ容器4をワンタッチで容易に開口することができる。
As shown in FIGS. 2 and 3, the spout 1 has a hollow pouring cylinder shape whose upper end is closed by a closing portion 5, and a lower portion thereof is a pouch welded portion. The spout 1 has a flat shape as can be seen from the vertical cross-sectional shapes of FIGS. 2 and 3, and has a substantially elliptical shape in cross-sectional shape.
The closing part 5 of the spout 1 is a peeling part 11 connected to the upper end of the spout tube of the spout 1 via a breakable weakening part 10, and an opening knob part 12 is provided in a part thereof, The opening knob 12 is provided with a hole 12a for a finger to enter. Therefore, the closing part 5 can be opened by inserting a finger into the hole 12 a of the opening knob part 12, crushing the weakening part 10 by applying a force in the peeling direction and removing the peeling part 11. As a result, the sealing property of the pouch container 4 is maintained, and the pouch container 4 can be easily opened with one touch.
図2、3に示す通り、前記スパウト1の下部のパウチ溶着部外周面には、その側面に横方向に延在する溶着用リブ6が形成されており、実施例では縦方向に一定間隔をおいて4本並んでいる。この溶着用リブ6は、スパウト1の下部の一側面に一のプラスチックフィルム2の側における周縁2bに溶着される第一溶着用リブ7と、他側面に他のプラスチックフィルム3の側における周縁3bに溶着される第二溶着用リブ8とで構成されている。溶着部の拡大側面図である図4を参照して理解されるように、第一溶着用リブ7、第二溶着用リブ8は注出筒の約半周分に亘って各々形成されており、上方から見て楕円形状を有する注出筒の楕円長軸の両端側において、第一溶着用リブ7と第二溶着用リブ8との境界が存在している。 As shown in FIGS. 2 and 3, the outer peripheral surface of the pouch welded portion at the lower part of the spout 1 is formed with welding ribs 6 extending in the lateral direction on the side surfaces. 4 of them are lined up. The welding rib 6 includes a first welding rib 7 which is welded to the peripheral edge 2b on one plastic film 2 side on one side surface of the lower part of the spout 1, and a peripheral edge 3b on the other plastic film 3 side to the other side surface. The second welding rib 8 is welded to the second welding rib 8. As will be understood with reference to FIG. 4, which is an enlarged side view of the welded portion, the first welding rib 7 and the second welding rib 8 are each formed over about a half circumference of the dispensing cylinder, A boundary between the first welding rib 7 and the second welding rib 8 exists on both ends of the elliptical long axis of the extraction cylinder having an elliptical shape when viewed from above.
そして、この溶着用リブ6における第一溶着用リブ7と第二溶着用リブ8とは、既述のとおり、縦方向断面形状の断面積が同一で、且つ第一溶着用リブ7の頂部の高さ(H1)は、第二溶着用リブ8の頂部の高さ(H2)より高く(H1>H2)形成されている。
図面を参照して本発明のスパウトをパウチに溶着する工程を説明する。
これにより、頂部の高さ(H1)の高い第一溶着用リブ7は、(H1−H2)の高さの溶着用リブ部分が初めの溶着(仮溶着)に利用されて、先にプラスチックフィルム2の周縁2bにのみ溶着される(図6参照)。すると、未溶着の第二溶着用リブ8とプラスチックフィルム3の周縁3bとの間に出来た開口部20(図7参照)から、パウチ4内に内容物を充填することが出来る(図8参照)。そのあと、第二溶着用リブ8の高さ(H2)と同じ高さ(H2)となった第一溶着用リブ7は、第二溶着用リブ8と同時にプラスチックフィルム2の周縁2bに再溶着されるが、互いのリブの同じ高さとなっている為、第一溶着用リブ7と第二溶着用リブ8は、均一な加熱がかかることになり、プラスチックフィルム3の周縁2b、3bに安定して溶着されて、開口部20が閉じられることになる。
As described above, the first welding rib 7 and the second welding rib 8 in the welding rib 6 have the same cross-sectional area in the longitudinal cross-sectional shape, and the top of the first welding rib 7 . The height (H1) is higher than the height (H2) of the top of the second welding rib 8 (H1> H2).
A process of welding the spout of the present invention to a pouch will be described with reference to the drawings.
As a result, the first welding rib 7 having a high top height (H1) is used in the first welding (temporary welding) with the welding rib portion having a height of (H1-H2). 2 is welded only to the peripheral edge 2b (see FIG. 6). Then, the contents can be filled into the pouch 4 from the opening 20 (see FIG. 7) formed between the unwelded second welding rib 8 and the peripheral edge 3b of the plastic film 3 (see FIG. 8). ). Thereafter, the first welding rib 7 having the same height (H2) as the height (H2) of the second welding rib 8 is re-welded to the peripheral edge 2b of the plastic film 2 simultaneously with the second welding rib 8. However, since the ribs have the same height, the first welding rib 7 and the second welding rib 8 are uniformly heated, and are stable on the peripheral edges 2b and 3b of the plastic film 3. As a result, the opening 20 is closed.
したがって、スパウト1の第一及び第二溶着用リブ7及び8と、プラスチックフィルム2及び3との溶着、すなわち、パウチ4の開口している部分の周縁2b及び3bとの溶着に、時間差を設けても、一方側を再溶着しても、より容易且つ確実に溶着することが可能となる。加えて、パウチ4の周縁2bにスパウト1の第一溶着用リブ7を溶着していても、パウチ4の周縁3bとスパウト1の第二溶着用リブ8とは未溶着であるから開いていて、その開口部20からパウチ4内に内容物を充填出来るため、パウチ4にスパウト1を溶着する際の位置的な制約が無くなる。このため、パウチ4にスパウト1を溶着する位置は、輸送や保管時に邪魔にならない位置(例えば中央部)にすることが出来、パウチの有効充填量が減らない位置とすることなども可能となる。 Therefore, a time difference is provided in the welding of the first and second welding ribs 7 and 8 of the spout 1 and the plastic films 2 and 3, that is, the welding of the peripheral edges 2b and 3b of the opened portion of the pouch 4. Even if one side is welded again, it becomes possible to weld more easily and reliably. In addition, even if the first welding rib 7 of the spout 1 is welded to the peripheral edge 2b of the pouch 4, the peripheral edge 3b of the pouch 4 and the second welding rib 8 of the spout 1 are open because they are not welded. Since the contents can be filled into the pouch 4 from the opening 20, there is no positional restriction when the spout 1 is welded to the pouch 4. For this reason, the position where the spout 1 is welded to the pouch 4 can be a position that does not interfere with transportation or storage (for example, the central portion), and can be a position where the effective filling amount of the pouch is not reduced. .
次に、上記構成になるスパウト1をパウチ4に採用した場合の包装体の製造方法について説明する。
まず、例えば、2枚の矩形のプラスチックフィルム2及び3の周縁2a及び3aにおける3辺を溶着し、袋状のパウチ4にする。そのあと、袋状のパウチ4の未溶着のスパウト溶着側周縁2b及び3bの間に、スパウト1の下部を挿入する(図5参照)。そして、溶着機のヒートシールバー21、22にて、パウチ4の周縁2bに、スパウト1の複数の溶着用リブ6のうち、第一溶着用リブ7のみを加熱溶着する(図6参照)。その溶着の際、第一溶着用リブ7に対応するヒートシールバー21を加熱状態、第二溶着用リブ8に対応するヒートシールバー22を非加熱状態でスパウトを挟み押圧することで、フィルム3側のみを非溶着状態にすると共に、第一溶着用リブ7における(H1−H2)の頂部の高さに相当する溶着用リブ部分を溶着材として利用し、パウチ4のフィルム2側にスパウト1を仮付けした状態(仮溶着状態)にする。
Next, a method for manufacturing a package when the spout 1 having the above-described configuration is employed in the pouch 4 will be described.
First, for example, three sides of the peripheral edges 2 a and 3 a of two rectangular plastic films 2 and 3 are welded to form a bag-like pouch 4. Thereafter, the lower portion of the spout 1 is inserted between the unwelded spout welding side peripheral edges 2b and 3b of the bag-like pouch 4 (see FIG. 5). And only the 1st welding rib 7 is heat-welded among the several welding ribs 6 of the spout 1 to the peripheral edge 2b of the pouch 4 with the heat seal bars 21 and 22 of a welding machine (refer FIG. 6). At the time of the welding, the heat seal bar 21 corresponding to the first welding rib 7 is heated and the heat seal bar 22 corresponding to the second welding rib 8 is pressed and sandwiched with the spout in a non-heated state. Only the side is made into a non-welded state, and the welding rib portion corresponding to the height of the top of (H1-H2) in the first welding rib 7 is used as a welding material, and the spout 1 is placed on the film 2 side of the pouch 4. Is temporarily attached (temporary welding state).
この状態では、第二溶着用リブ8と袋状のパウチ4の周縁3bとは溶着されていないから、前記開口部20が形成されて(図7参照)、その開口部20から内容物をパウチ4内に充填でき(図8参照)、内容物の充填後に、今度はヒートシールバー21、22の両方を加熱状態でスパウトを挟み押圧することにより第一溶着用リブ7、第二溶着用リブ8と袋状のパウチ4の周縁2b、3bとを完全に溶着した状態(本溶着状態)にする。このようにして開口部20を閉じれば(図9参照)、内容物収納済みの本発明のスパウト1を装着したパウチ4の商品化が完成して(図10参照)、パウチ4の密封性が高く保持された、輸送や保管が容易な商品として、市場に流通させることが出来る。この商品を手にした消費者は、スパウト1の開口用つまみ部12の孔12aに手指を差し込み、引き剥がし方向に力を加え弱化部10を破砕して、引き剥がし部11を除去することで閉塞部6を開口でき、内容物を利用することも出来る。このように予め、第一溶着用リブ7の高さを第二溶着用リブ8の高さより高く、また両者の断面積を同一にすることで、片面側の仮溶着、両面側の本溶着という二回の溶着行程を経た場合でも安定した溶着が可能となるのである。 In this state, since the second welding rib 8 and the peripheral edge 3b of the bag-like pouch 4 are not welded, the opening 20 is formed (see FIG. 7), and the contents are pouched from the opening 20. 4 can be filled (see FIG. 8), and after filling the contents, the first welding rib 7 and the second welding rib are obtained by sandwiching and pressing both the heat seal bars 21 and 22 in a heated state. 8 and the peripheral edges 2b and 3b of the bag-like pouch 4 are completely welded (main welding state). If the opening 20 is closed in this way (see FIG. 9), the commercialization of the pouch 4 fitted with the spout 1 of the present invention containing the contents is completed (see FIG. 10), and the sealing performance of the pouch 4 is improved. It can be distributed in the market as a highly held product that is easy to transport and store. A consumer who has obtained this product inserts his / her finger into the hole 12a of the opening knob 12 of the spout 1, applies force in the peeling direction, crushes the weakened portion 10, and removes the peeling portion 11. The closing part 6 can be opened and the contents can be used. In this way, the height of the first welding rib 7 is higher than the height of the second welding rib 8 in advance, and the cross-sectional areas of both are the same, so that the temporary welding on one side and the main welding on both sides are called. Stable welding is possible even after two welding steps.
以上、本発明の実施例1を説明したが、具体的な構成はこれに限定されず、本発明の要旨を逸脱しない範囲での変更は、適宜可能であることが理解されるべきである。 While the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that modifications can be made as appropriate without departing from the scope of the present invention.
本発明のスパウトは、ワンピースタイプのスパウトにして、輸送や保管時にスパウトが邪魔にならず、パウチの有効充填量が減らず、しかも仮溶着工程と本溶着工程の間に内容物充填工程を介在させることが出来るため、スタンディングパウチにも適用できて内容物をスムーズに充填したい場合に、その利用可能性が極めて高くなる。 The spout of the present invention is a one-piece type spout, which does not interfere with the spout during transportation and storage, does not reduce the effective filling amount of the pouch, and intervenes the content filling process between the temporary welding process and the main welding process. Therefore, when it can be applied to a standing pouch and it is desired to fill the contents smoothly, its availability becomes extremely high.
