Description

本発明は、食品や飲料、洗剤などの収容物を収容する軟包装袋の端縁部に熱溶着などの手段で取り付けられる注出口に関するものであり、さらに述べると注出口と閉塞栓が一体に形成された閉塞栓一体型注出口に関するものである。 The present invention relates to a spout attached to an end edge of a flexible packaging bag that contains a container such as food, beverage, or detergent by means of heat welding or the like. The present invention relates to a formed closure plug-integrated spout.

従来から上記の軟包装袋は廉価であり、取扱いが容易であるため広く利用されている。さらに近年においては収容物の注出性を高めるために、合成樹脂製の注出口を軟包装袋の端縁部に熱溶着等の手段で装着することがおこなわれている。これらの注出口は軟包装袋の廉価である利点を損なわないように、本体部と閉塞栓とが薄肉部を介して一体に形成され、販売時には軟包装袋を密封状態に保ち、消費者が使用する際には前記薄肉部を破断して注出開口を形成するとともに、使用後には注出開口を閉塞栓で再封止できる機能を備えている。（例えば、特許文献１参照。） Conventionally, the above-mentioned flexible packaging bags are widely used because they are inexpensive and easy to handle. Furthermore, in recent years, in order to improve the pouring property of the contents, a synthetic resin pouring outlet is attached to the edge of the flexible packaging bag by means such as heat welding. These spouts are formed so that the main body and the closure plug are integrally formed through the thin wall portion so as not to impair the inexpensive advantage of the flexible packaging bag. When used, the thin-walled portion is broken to form a dispensing opening, and after use, the dispensing opening is re-sealed with a closing plug. (For example, refer to Patent Document 1.)

特開平１１−２２７８０８JP-A-11-227808

而して上記従来の閉塞栓一体型注出口は、開栓に際して把持片が小さいため薄肉部の破断が容易でなく、また再開栓に際して閉塞栓を離脱し難いという問題があり、特に高齢者や子供にとっては非常に困難な作業となる。また軟包装袋は柔軟な合成樹脂シートを袋状に形成したものであるため、収容物が少なくなるにつれて軟包装袋の自立安定性が悪くなり倒れる虞がある。この衝撃により閉塞栓が本体部から外れ、収容物が漏出するという問題点がある。 Thus, the above-mentioned conventional closure plug-integrated spout has a problem that it is difficult to break the thin-walled portion because the grip piece is small at the time of opening, and it is difficult to remove the closure plug at the time of reopening. This is a very difficult task for children. Further, since the flexible packaging bag is formed by forming a flexible synthetic resin sheet into a bag shape, there is a possibility that the self-supporting stability of the flexible packaging bag is deteriorated and falls as the amount of stored items decreases. Due to this impact, there is a problem that the closure plug is detached from the main body and the contents are leaked.

本発明は、上記のような問題点に鑑みなされたものであり、その主たる技術的課題は、低コストで再封止機能を有し、開栓にあたっては本体部と閉塞栓を接続する薄肉部を容易に破断して注出開口を形成することができ、再開栓にあたって容易に閉塞栓を離脱でき、しかも外部からの衝撃により閉塞栓が不意に外れて収容物が漏出するのを有効に防止した注出口を提供することにある。 The present invention has been made in view of the above-described problems, and the main technical problem thereof is a low-cost re-sealing function, and a thin-walled portion that connects the main body portion and the closing plug when opening the plug. Can be easily broken to form a dispensing opening, and the closure plug can be easily removed at the time of restarting the plug, and effectively prevents the closure plug from being accidentally removed due to an external impact. Is to provide a spout.

本発明は、上記目的を達成するために提案されたものであって、下記の構成からなることを特徴とする。
本発明の注出口は本体部と、指掛け部を有する閉塞栓とを具備するものとし、本体部は注出筒を有しており、その一端には注出筒と連通する注出路を有する菱形状の取付け部が連続して形成され、他端には薄肉部を介して注出筒の先端を塞ぐ閉塞栓が連続して形成されるとともに、注出筒の外周面には開栓補助突起が形成され、閉塞栓には当接部が配設されていることを特徴とする。本発明によれば、前記開栓補助突起は、注出筒の中心線に対し傾斜状に形成されていることを特徴とする。本発明によれば、前記開栓補助突起は、注出筒の中心線に対して傾斜する少なくとも１の傾斜部を有する環状突起であり、環状突起は最下点と最上点とを有することを特徴とする。本発明によれば、環状突起の最下点は菱形形状取付け部の長手方向中心線上に位置し、最上点は前記中心線に直交する直交線上に位置することを特徴とする。本発明によれば、前記閉塞栓は注出筒の内面に液密に嵌入する嵌入突部と、一対の指掛け部とを備えており、嵌入突部と指掛け部との間には注出筒の開口端部を挟持する間隙が形成されているとともに、該嵌入突部と対向する指掛け部内端に前記当接部が形成されていることを特徴とする。本発明によれば、前記本体部と閉塞栓は連結片で接続されていることを特徴とする。 The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
The spout according to the present invention includes a main body portion and an obturator plug having a finger hook portion. The main body portion has a pouring tube, and one end thereof has a pouring path communicating with the pouring tube. The shape-shaped mounting part is continuously formed, and the other end is continuously formed with a blocking plug that closes the tip of the dispensing tube via the thin wall part, and the plug opening auxiliary projection on the outer peripheral surface of the dispensing tube Is formed, and the closing plug is provided with a contact portion. According to the present invention, the opening assisting protrusion is formed to be inclined with respect to the center line of the dispensing cylinder. According to the present invention, the opening assistance protrusion is an annular protrusion having at least one inclined portion inclined with respect to the center line of the dispensing cylinder, and the annular protrusion has a lowest point and an uppermost point. Features. According to the present invention, the lowest point of the annular protrusion is located on the longitudinal center line of the rhombus-shaped mounting portion, and the highest point is located on an orthogonal line orthogonal to the center line. According to the present invention, the closing plug includes a fitting protrusion that is liquid-tightly fitted on the inner surface of the dispensing tube and a pair of finger hooks, and the dispensing tube is between the fitting protrusion and the finger hooking portion. A gap for sandwiching the opening end of the finger is formed, and the contact portion is formed at the inner end of the finger-hanging portion facing the fitting protrusion. According to the present invention, the main body and the closing plug are connected by a connecting piece.

本発明の注出口は、容易に注出開口を形成せしめることができ、さらに再開栓時においても注出筒の外面に形成した開栓補助突起に閉塞栓の当接部が摺動回転しながら閉塞栓が上方へ移動せしめられるため容易に開栓することができる。また上記の開栓補助突起の最下点を注出口本体の菱形形状取付け部の長手方向の中心線に配設し、閉栓時に当接部が該中心線の上方に位置する構成としたため、指掛け部が外方に突出することなく、外部からの衝撃により閉塞栓が外れることもない。 The spout of the present invention can easily form a spout opening, and even when reopening, the stopper plug abutment formed on the outer surface of the spout tube slides and rotates while the stopper plug abutment portion slides and rotates. Since the plug is moved upward, it can be easily opened. In addition, the lowest point of the above-mentioned opening assistance protrusion is arranged on the center line in the longitudinal direction of the rhombus-shaped mounting portion of the spout main body, and the contact portion is positioned above the center line when closing the plug. The part does not protrude outward, and the blocking plug does not come off due to an external impact.

以下本発明に従って構成された注出口の好適実施形態を添付図面に基づいて詳細に説明する。 A preferred embodiment of a spout constructed according to the present invention will be described below in detail with reference to the accompanying drawings.

図１乃至図４を参照して説明すると、本発明に従って構成された全体を１で示す注出口はポリプロピレン又はポリエチレンの如き適宜の合成樹脂から一体に形成されている。以下さらに詳細に説明すると、注出口１は本体部２と閉塞栓３とを主な構成要素とし、図４に示すように両者は破断可能な薄肉部４を介して一体に形成されている。薄肉部４は材料厚さを低減せしめた所謂スコアから形成されている。本体部２と閉塞栓３とは細紐状の連結片１６で接続されており、開栓後に閉塞栓３を紛失することがない構成となっている。連結片１６は輸送時等に注出口同士が絡まらないように破断可能なブリッジ１７で保持されている。 Referring to FIG. 1 to FIG. 4, the spout indicated as 1 as a whole constructed according to the present invention is integrally formed from a suitable synthetic resin such as polypropylene or polyethylene. In more detail, the spout 1 has a main body 2 and an obturator plug 3 as main components, and both are integrally formed through a thin portion 4 that can be broken as shown in FIG. The thin portion 4 is formed of a so-called score in which the material thickness is reduced. The main body 2 and the closing plug 3 are connected by a thin string-like connecting piece 16 so that the closing plug 3 is not lost after opening. The connecting piece 16 is held by a breakable bridge 17 so that the spouts do not get entangled during transportation or the like.

本体部２は円筒状の注出筒５を有する。この注出筒５の一端には注出筒と連通する注出路１８を内部に形成した取付け部１９が連続しており、図３に示すように平面図上菱形形状に形成されている。取付け部１９は図示しない軟包装袋の端縁部に取付け部の両側面を挟み込んだ状態で熱溶着等の手段で取付けられる。なお、図１で示すように取付け面には縦方向リブ７、横方向リブ６が複数本配設されているとともに、長手方向両端には薄肉の舌片８が形成されている。これは取付け時における軟包装袋と注出口の溶着力を強固なものとするために配設されるものである。 The main body 2 has a cylindrical dispensing cylinder 5. At one end of the pouring cylinder 5, a mounting portion 19 having a pouring path 18 communicating with the pouring cylinder is continuous, and is formed in a diamond shape on the plan view as shown in FIG. The attachment portion 19 is attached by means such as heat welding in a state where both side surfaces of the attachment portion are sandwiched between end edges of a soft packaging bag (not shown). As shown in FIG. 1, a plurality of longitudinal ribs 7 and transverse ribs 6 are disposed on the mounting surface, and thin tongue pieces 8 are formed at both ends in the longitudinal direction. This is provided in order to strengthen the welding force between the soft packaging bag and the spout at the time of attachment.

注出筒５の他端には破断可能な薄肉部４を介して閉塞栓３が連続形成されている。この閉塞栓３は、注出筒の開口端部内面に液密に嵌入する嵌入突部１１と、一対の平板状の指掛け部１０とを主な構成要素とする。嵌入突部１１と指掛け部１０との間には閉栓時に注出筒の開口端部を挟持する間隙１５が形成され、嵌合突部１１と対向する指掛け部１０の内端には切欠き状の当接部１４が形成されている。このような構成とすることで、当接部１４が突出しないため衝撃等により閉塞栓３が本体部２から分離して収容物が漏出するのを防止することができる。嵌入突部１１の外面には注出筒の内面に嵌合する嵌入突条１２が形成され、再閉栓時に密封状態を保持する。指掛け部１０は、平板状の指掛け面であり、その縁部は滑り止めのため肉厚１３になっている。 A blocking plug 3 is continuously formed at the other end of the dispensing cylinder 5 through a thin portion 4 that can be broken. The obturator plug 3 includes a fitting protrusion 11 that is liquid-tightly fitted on the inner surface of the opening end of the dispensing cylinder, and a pair of flat finger rests 10 as main components. A gap 15 is formed between the fitting protrusion 11 and the finger hooking portion 10 so as to sandwich the opening end of the extraction tube when the plug is closed, and the inner end of the finger hooking portion 10 facing the fitting protrusion 11 is notched. The contact portion 14 is formed. By adopting such a configuration, since the contact portion 14 does not protrude, it is possible to prevent the closure plug 3 from being separated from the main body portion 2 due to an impact or the like and the contents to be leaked. An insertion protrusion 12 is formed on the outer surface of the insertion protrusion 11 to be fitted to the inner surface of the dispensing cylinder, and keeps a sealed state at the time of reclosing. The finger-hanging portion 10 is a flat-shaped finger-hanging surface, and its edge portion has a thickness 13 for preventing slippage.

さらに説明を続けると、注出筒５の外面には開栓補助突起９が形成されている。該開栓補助突起９は再開栓時に容易に閉塞栓を取り外すための補助突起であり、本発明における最も重要な特徴である。図１に示すように開栓補助突起９は注出筒の中心線Ｌ（ここでいう中心線Ｌとは、注出筒５の中心を通る垂直方向の線のことをいう。）に対し傾斜状に形成され、最良の実施形態として、図１、図２に示すように中心線Ｌに対して傾斜する傾斜部を有する環状突起であることが好ましい。前記環状突起は最下点２１と最上点２２とを有しており、最下点２１は図３に示す菱形形状取付け部１９の長手方向の中心線Ｍ（ここでいう長手方向の中心線Ｍとは、注出筒の直径と菱形形状取付け部１９の長手方向の対角線とを通る線のことをいう。）上に位置し、最上点２２は前記中心線Ｍに直交する直交線Ｎ上に位置している。 If the description is further continued, an opening assisting protrusion 9 is formed on the outer surface of the dispensing tube 5. The plug opening auxiliary projection 9 is an auxiliary projection for easily removing the blocking plug at the time of restart plugging, and is the most important feature in the present invention. As shown in FIG. 1, the opening assisting projection 9 is inclined with respect to the center line L of the dispensing cylinder (here, the center line L is a vertical line passing through the center of the dispensing cylinder 5). It is preferable that the protrusion is an annular protrusion having an inclined portion that is inclined with respect to the center line L as shown in FIGS. The annular protrusion has a lowermost point 21 and an uppermost point 22, and the lowermost point 21 is a longitudinal center line M (the longitudinal center line M here) of the rhombus-shaped mounting portion 19 shown in FIG. 3. Means a line passing through the diameter of the dispensing cylinder and the diagonal line in the longitudinal direction of the rhombus-shaped mounting portion 19. The uppermost point 22 is on an orthogonal line N orthogonal to the center line M. positioned.

次に、本発明の注出口の使用方法について詳述する。収容物を軟包装袋から最初に取り出すに際しては、閉塞栓３を図３で示す開栓方向Ａ（例えば反時計周り）に力を加えると薄肉部４が破断して注出開口が形成される。指掛け部１０は平板状の指掛け面であり、指掛け面の周縁を肉厚１３に形成したので、指が滑ることなく、容易に薄肉部４を破断することができる。適宜収容物を注ぎ出した後、分離された閉塞栓３の嵌入突部１１を図５、図６に示すように逆さ方向（図上、下方向）に向けて注出筒の開口端部に嵌入させると嵌入突条１２が注出筒５の内面に液密に嵌合するので、内容物が漏出することはない。また、図３に示すように開栓補助突起９の最下点２１を菱形形状取付け部の長手方向の中心軸線Ｍ上に位置せしめ、最下点２１の上方に当接部１４を位置せしめたので、指掛け部１０は中心軸線Ｍと同一平面上の閉栓位置に保持される。前記閉栓位置とすることで外部からの衝撃が注出口に加わっても、閉塞栓３が不意に外れ難く、収容物の漏出の心配がない。 Next, the method for using the spout of the present invention will be described in detail. When the contents are first taken out from the flexible packaging bag, if the closing plug 3 is applied with force in the opening direction A shown in FIG. 3 (for example, counterclockwise), the thin-walled portion 4 is broken and a dispensing opening is formed. . The finger hooking portion 10 is a flat finger hooking surface, and since the periphery of the finger hooking surface is formed with a thickness of 13, the thin wall portion 4 can be easily broken without the finger slipping. After pouring out the contents as appropriate, the fitting protrusion 11 of the separated plug 3 is directed in the inverted direction (upward and downward in the drawing) as shown in FIGS. When fitted, the fitting ridge 12 is fitted in a liquid-tight manner to the inner surface of the dispensing cylinder 5, so that the contents do not leak out. Further, as shown in FIG. 3, the lowest point 21 of the opening assisting protrusion 9 is positioned on the central axis M in the longitudinal direction of the rhombus-shaped mounting part, and the contact part 14 is positioned above the lowest point 21. Therefore, the finger-hanging portion 10 is held at the closing position on the same plane as the central axis M. Even when an impact from the outside is applied to the spout by setting the closing position, the closing plug 3 is not easily removed unexpectedly, and there is no fear of leakage of the contents.

再開栓に際して、指掛け部１０に指を掛け、図３に示したのと同方向Ａに閉塞栓３を回転させると、図５に示す開栓補助突起９の上段面を閉塞栓の当接部１４が摺動していき、次第に斜め上方に移動する。さらに閉塞栓３を回転させると、嵌入突部１１が注出筒５から外れ、開栓が完了する。 When resuming the stopper, the finger hooking part 10 is put on a finger, and when the closing plug 3 is rotated in the same direction A as shown in FIG. 3, the upper surface of the opening assisting protrusion 9 shown in FIG. 14 slides and gradually moves obliquely upward. When the plug 3 is further rotated, the fitting protrusion 11 is detached from the dispensing tube 5 and the plug opening is completed.
