The plug comprises a knob portion and a plug portion that fits into the spout main body portion. The plug portion includes a short-diameter portion formed below the cylindrical portion following the bottom surface of the knob portion, and a horizontal axis orthogonal to the short-diameter portion. A long-diameter portion projecting in the direction, and an upper surface of the long-diameter portion is formed at a predetermined interval from an annular protrusion formed on the lower surface of the knob portion. An engagement protrusion having a thickness corresponding to a predetermined interval formed on the plug portion is formed by extending inward in the horizontal direction, and connects the upper end inner peripheral surface of the spout main body portion and the tip outer peripheral surface of the plug portion to a thin wall portion. Is formed, and the engaging protrusion of the spout main body is sandwiched between the annular protrusion of the removed stopper and the upper surface of the long diameter portion at the time of resealing. Configuration the spout-equipped bag-like container closure is disclosed urchin.
特許文献１，２等に開示されるように、これまでの、栓体をスパウト部の端部に薄肉部を介して連結した袋状容器用スパウトにおいては、栓体の上面に、つまみ用突起を設けていた。そして、つまみ用突起を掴んで栓体を押し上げて薄肉部を破断し、栓体をスパウト部から取外して、袋状容器を開閉していた。 As disclosed in Patent Documents 1 and 2, etc., in a spout for a bag-like container in which a stopper is connected to an end of a spout part through a thin part, a protrusion for a knob is formed on the upper surface of the stopper. Was established. Then, the handle was pushed up and the stopper was pushed up to break the thin portion, the stopper was removed from the spout, and the bag-like container was opened and closed.
しかしながら、つまみ用突起は、ある程度の高さや幅を有していないと、しっかりとつまむことができず、栓体の取外し作業性が低下する。このため、栓体の上面につまみ用突起を形成すると、袋状容器全体の製品高さが大きくなり、外観が悪くなったり、製品を陳列する際に設置スペースが嵩む等の問題が生じることがあった。 However, if the knob protrusion does not have a certain height or width, it cannot be pinched firmly, and the removal workability of the plug body is lowered. For this reason, when the protrusions for knobs are formed on the upper surface of the stopper, the product height of the entire bag-like container increases, which may cause problems such as poor appearance and increased installation space when displaying the products. there were.

次に、スパウト１０について説明する。 Next, the spout 10 will be described.
図２，３に示されるように、このスパウト１０は、袋状容器本体５０の表裏のシート材５１に挟まれて溶着される溶着部１１と、溶着部１１から立設され、袋状容器本体５０内部に連通する筒状のスパウト部１２と、スパウト部１２の端部に破断可能な薄肉部１５を介して連結され、スパウト部１２の端部を閉塞する栓体２０とで主に構成されている。 As shown in FIGS. 2 and 3, the spout 10 has a welded portion 11 sandwiched and welded between sheet materials 51 on the front and back of the bag-like container body 50, and a bag-like container body standing from the welded portion 11. 50 is mainly composed of a cylindrical spout portion 12 communicating with the inside, and a plug body 20 connected to an end portion of the spout portion 12 through a thin portion 15 that can be broken and closing the end portion of the spout portion 12. ing.
スパウト部１２の下方には、溶着部１１から所定間隔Ｌをおいてフランジ部１３が設けられている。このフランジ部１３は、スパウト付き袋状容器６０を搬送する際のハンガーとして利用されるが、必ずしも必要なものではない。 A flange portion 13 is provided below the spout portion 12 with a predetermined distance L from the weld portion 11. Although this flange part 13 is utilized as a hanger at the time of conveying the bag-like container 60 with a spout, it is not necessarily required.
栓体２０は、スパウト部１２の端部に環状の薄肉部１５を介して連結された筒部２１と、筒部２１の端面を閉塞すると共に筒部２１の外方に延出されたつまみ用フランジ２２と、つまみ用フランジ２２の筒部２１と反対の外側面から突設された突起２３とを有している。 The plug body 20 is connected to the end portion of the spout portion 12 via an annular thin portion 15, and for the knob that closes the end surface of the tube portion 21 and extends outward from the tube portion 21. It has a flange 22 and a protrusion 23 protruding from the outer surface opposite to the cylindrical portion 21 of the knob flange 22.
図２に示されるように、栓体２０の筒部２１は、基部２１ａと、テーパ状に縮径した縮径部２１ｂとで構成され、縮径部２１ｂが、スパウト部１２内に挿入配置されている。基部２１ａの外周には、環状のリブ２１ｃが突設されている。 As shown in FIG. 2, the cylindrical portion 21 of the plug body 20 is composed of a base portion 21 a and a reduced diameter portion 21 b that has a tapered diameter, and the reduced diameter portion 21 b is inserted into the spout portion 12. ing. An annular rib 21c protrudes from the outer periphery of the base 21a.
基部２１ａ及びリブ２１ｃは、薄肉部１５を破断して栓体２０をスパウト部１２から分離された状態で、スパウト部１２の破断された開口部に差し込み可能な外径とされていることが好ましい。この部分の最大径となるリブ２１ｃの外径（以下、筒部２１の最大径ともいう）は、スパウト部１２の内径の１００〜１１０％が好ましく、１００〜１０２％がより好ましい。筒部２１の最大径が上記範囲であれば、スパウト部１２の開口部に栓体２０を容易かつ気密性よく差し込むことができる。 The base 21a and the rib 21c preferably have outer diameters that can be inserted into the broken opening of the spout 12 in a state where the thin wall 15 is broken and the plug 20 is separated from the spout 12. . The outer diameter of the rib 21c (hereinafter also referred to as the maximum diameter of the cylindrical portion 21), which is the maximum diameter of this portion, is preferably 100 to 110%, more preferably 100 to 102% of the inner diameter of the spout portion 12. If the maximum diameter of the cylinder part 21 is the said range, the plug body 20 can be inserted in the opening part of the spout part 12 easily and airtightly.
栓体２０のつまみ用フランジ２２は、溶着部１１に溶着される袋状容器本体５０の扁平方向に長く、その扁平方向において筒部２１の外径より突出している。栓体２０のつまみ用フランジ２２の、上記方向における筒部２１の外径からの突出長さＬ１は、３ｍｍ以上が好ましく、５〜１０ｍｍがより好ましい。つまみ用フランジ２２が、上記方向において筒部２１の外径より突出していることにより、つまみ用フランジ２２を押し上げて薄肉部１５を簡単に破断でき、栓体２０をスパウト部１２から容易に取外すことができる。そして、つまみ用フランジ２２の突出長さＬ１が３ｍｍ以上であれば、つまみ用フランジ２２をより押し上げ易くなり、栓体２０をスパウト部１２から作業性よく取外しできる。 The knob flange 22 of the plug body 20 is long in the flat direction of the bag-like container body 50 welded to the welded portion 11 and protrudes from the outer diameter of the cylindrical portion 21 in the flat direction. The protrusion length L1 of the knob flange 22 of the plug body 20 from the outer diameter of the cylindrical portion 21 in the above direction is preferably 3 mm or more, and more preferably 5 to 10 mm. Since the knob flange 22 protrudes from the outer diameter of the cylindrical portion 21 in the above direction, the thin flange portion 15 can be easily broken by pushing up the knob flange 22, and the plug body 20 can be easily removed from the spout portion 12. Can do. If the protruding length L1 of the knob flange 22 is 3 mm or more, the knob flange 22 can be more easily pushed up, and the plug body 20 can be removed from the spout portion 12 with good workability.
栓体２０の突起２３は、中央部が最も高くなるように突出し、周縁が次第に低くなる形状をなしている。このような形状の突起としては、図５（ａ）〜（ｄ）に示す形状の突起が好ましい一例として挙げられる。図５（ａ）の突起２３１は、半球状をなしている。図５（ｂ）の突起２３２は、平面方向から見た突起の長軸が、溶着部１１に溶着される袋状容器の扁平方向に沿って伸びた半楕円体状をなしている。図５（ｃ）の突起２３３は、円錐状をなしている。図５（ｄ）の突起２３４は、円錐の頂部２３４ａが曲面状をなしている。なお、この他に、三角錐、四角錐などの角錐体状をなす突起や、角錐体の頂部が曲面状をなす突起などを採用することもできる。 The projection 23 of the plug body 20 has a shape in which the central portion protrudes so as to be the highest and the peripheral edge gradually becomes lower. As a projection having such a shape, projections having the shapes shown in FIGS. 5A to 5D are preferable examples. The protrusion 231 in FIG. 5A has a hemispherical shape. The protrusion 232 in FIG. 5B has a semi-ellipsoidal shape in which the long axis of the protrusion viewed from the plane direction extends along the flat direction of the bag-like container welded to the welded portion 11. The protrusion 233 in FIG. 5C has a conical shape. In the protrusion 234 in FIG. 5D, the top 234a of the cone has a curved surface shape. In addition to this, a projection having a pyramid shape such as a triangular pyramid or a quadrangular pyramid, or a projection having a curved top shape of the pyramid may be employed.
突起２３の、つまみ用フランジ２２からの突出高さＨは、１〜８ｍｍが好ましく、３〜５ｍｍがより好ましい。突出高さＨが１ｍｍ未満であると、スパウト付き袋状容器６０が逆さに落下したときにスパウト１０を横に倒す効果が乏しくなり、衝撃吸収効果が低減する。突出高さＨが８ｍｍを超えると、袋状容器全体の製品高さが大きくなり、外観が悪くなったり、製品を陳列する際に設置スペースが嵩む等の問題が生じる。 The protrusion height H of the protrusion 23 from the knob flange 22 is preferably 1 to 8 mm, and more preferably 3 to 5 mm. When the protruding height H is less than 1 mm, the effect of tilting the spout 10 to the side when the spout-equipped bag-like container 60 drops upside down is reduced, and the impact absorbing effect is reduced. When the protrusion height H exceeds 8 mm, the product height of the entire bag-like container increases, and problems such as poor appearance and increased installation space occur when the product is displayed.
平面方向から見た突起２３の基部における最大外径Ｌ２は、１ｍｍ以上であることが好ましく、２〜１６ｍｍであることがより好ましい。上記外径Ｌ２が１ｍｍ未満あると、突起が先鋭となりやすく、指等に引っ掛かりやすくなる。 The maximum outer diameter L2 at the base of the protrusion 23 viewed from the plane direction is preferably 1 mm or more, and more preferably 2 to 16 mm. When the outer diameter L2 is less than 1 mm, the protrusion is likely to be sharp and easily caught on a finger or the like.
スパウト１０の各部材の材質は、特に限定は無く、従来の袋状容器用スパウトに用いられている材料を用いることができる。例えば、低密度ポリエチレン（ＬＤＰＥ）、直鎖低密度ポリエチレン（ＬＬＤＰＥ）、高密度ポリエチレン（ＨＤＰＥ）、ポリプロピレン（ＰＰ）等が挙げられる。 The material of each member of the spout 10 is not particularly limited, and materials used for conventional bag-shaped container spouts can be used. Examples thereof include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), and polypropylene (PP).
このスパウト付き袋状容器は、栓体２０のつまみ用フランジ２２の筒部２１と反対の外側面に、中央部が最も高くなるように突出し、周縁が次第に低くなる形状の突起２３が形成されているので、スパウト付き袋状容器６０が逆さに落下したとき、突起２３が落下面に衝突してスパウト１０を傾けさせて落下するので、落下衝撃がスパウト１０の薄肉部１５にかかるのを軽減することができ、薄肉部１５が破断したり、ひび割れしたりして、内容物が漏洩することを防止することができる。 This spout-equipped bag-like container is formed with a projection 23 having a shape that protrudes so that the center portion becomes the highest and the periphery gradually decreases on the outer surface opposite to the cylindrical portion 21 of the knob flange 22 of the plug body 20. Therefore, when the spout-equipped bag-like container 60 falls upside down, the protrusion 23 collides with the dropping surface and tilts the spout 10 to drop, so that the impact of the drop impact on the thin portion 15 of the spout 10 is reduced. It is possible to prevent the thin portion 15 from breaking or cracking and leaking the contents.
また、スパウト１０の栓体２０は、つまみ用フランジ２２を有するので、つまみ用フランジ２２と筒部２１との間に指をひっかけるなどしてつまみ用フランジ２２を押し上げて、薄肉部１５を簡単に破断でき、栓体２０をスパウト部１２から容易に取外すことができる。 Further, since the plug 20 of the spout 10 has the knob flange 22, the knob flange 22 is pushed up by, for example, hooking a finger between the knob flange 22 and the cylindrical portion 21, so that the thin portion 15 can be easily formed. The plug body 20 can be broken and can be easily removed from the spout portion 12.
また、スパウト部から取り外した栓体２０は、図４の仮想線に示すように、栓体２０の筒部２１を、スパウト部１２の開口に嵌挿することで、スパウト部１２を簡単にリキャップできる。 In addition, the plug body 20 removed from the spout portion can be easily recapped by inserting the cylindrical portion 21 of the plug body 20 into the opening of the spout portion 12 as shown by the phantom line in FIG. it can.
図６，７に示すスパウトの溶着部１１を、シート材（酸化アルミナ蒸着ポリエステル（透明蒸着−ＰＥＴ）１２μｍ／二軸延伸ナイロン（ＯＮＹ）１５μｍ／直鎖状低密度ポリエチレン（ＬＬＤＰＥ）１００μｍ）で挟持させて溶着し、内容物としてゼリーを約７０ｇ充填し、製造例１〜８のスパウト付き袋状容器（総重量約７５ｇ）を製造した。各製造例で使用したスパウト及び寸法を表１にまとめて記す。 The spout weld 11 shown in FIGS. 6 and 7 is sandwiched between sheet materials (alumina oxide-deposited polyester (transparent deposition-PET) 12 μm / biaxially stretched nylon (ONY) 15 μm / linear low density polyethylene (LLDPE) 100 μm)). Then, about 70 g of jelly was filled as the contents, and a spouted bag-like container (total weight: about 75 g) of Production Examples 1 to 8 was produced. The spout and dimensions used in each production example are summarized in Table 1.
なお、図６のスパウト１０ａは、栓体２０のつまみ用フランジ２２上に、半球状（直径３ｍｍ）の突起２３１が形成されている。 6 has a hemispherical (diameter 3 mm) protrusion 231 formed on the knob flange 22 of the plug 20.
また、図７のスパウト１０ｂは、栓体２０のつまみ用フランジ２２の上面が平坦となっており、突起が形成されていない。 In the spout 10b of FIG. 7, the upper surface of the knob flange 22 of the plug body 20 is flat, and no protrusion is formed.
製造例１、２のスパウト付き袋状容器（ｎ＝３）について落下試験を行い、１個でも内容物の漏れがあるものを×とし、全ての試験品で漏れが無いものを○とした。結果を表２にまとめて記す。なお、落下試験は、スパウト付き袋状容器を、１５０ｃｍの高さで、スパウト側からガイドによりまっすぐに落下させる操作を３回行った。 A drop test was performed on the spouted pouch-shaped containers (n = 3) of Production Examples 1 and 2, and even if there was a leak of the contents even one piece was rated as x, and all the test articles were marked as o. The results are summarized in Table 2. In addition, the drop test performed the operation which drops a bag-like container with a spout straight at 150 cm in height with a guide from the spout side three times.
表２の結果から明らかなように、栓体のつまみ用フランジ上に、中央部が最も高くなるように突出し、周縁が次第に低くなる突起を形成したことにより、スパウト付き袋状容器が逆さに落下したときに、落下衝撃がスパウトの薄肉部にかかるのを軽減することができ、内容物が漏洩することを防止することができた。 As is clear from the results of Table 2, the spout-equipped bag-like container falls upside down on the knob flange of the plug body by projecting so that the center part becomes the highest and the periphery gradually decreases. It was possible to reduce the impact of the drop impact on the thin part of the spout, and to prevent the contents from leaking.
