Description
本発明は、アルミシートやフィルムシートなどの包装材で加工されたパウチ容器の開口部に熱溶着された注出口を有するスパウトへ被せるヒンジキャップに関するものである。 The present invention relates to a hinge cap that is placed over a spout having a spout heat-welded to the opening of a pouch container made of a packaging material such as an aluminum sheet or a film sheet.
軽量で収縮性があり、容器としてかさ張らず、内容物が空気に触れにくく保存性が高いなどの利点から、近年アルミシートやフィルムシートなどの基材を加工した軟包装、いわゆるパウチ容器にレトルト食品や、飲料、ゼリー、調味料、詰め替えの洗剤やシャンプーなどの内容物を詰めた商品が多く店頭に陳列されている。パウチ容器には、内容物を注ぎやすくするために、特許文献１に記載のようなプラスチックで成形したスパウトが袋体を有するパウチ容器の開口部分に熱溶着されているものがある。 In recent years, flexible packaging made from base materials such as aluminum sheets and film sheets, so-called pouch containers, have been used for retort food, due to their advantages such as being lightweight and shrinkable, not bulky as containers, and preventing the contents from coming into contact with air and having a long shelf life. There are many products on display in stores that contain contents such as drinks, jellies, seasonings, and refillable detergents and shampoos. Some pouch containers have a spout made of plastic, such as that described in Patent Document 1, that is heat-welded to the opening of the pouch container to facilitate pouring of the contents.
このようなスパウトには、キャップと螺合するように、スパウトの外周側壁面にネジが形成されている。また、前記スパウトのネジには水抜きスリットが形成されているものがあり、前記水抜きスリットの役目としては、特許文献２に記載のように、パウチに内容物を充填しキャップで開口部を閉じた後、レトルト（加圧滅菌用釜）に入れ、湯煎などの加熱殺菌を行う場合があり、レトルトを行うことでスパウトとキャップの間に入りこんだ水を水抜きスリットから下方へ流し出すためである。 Such a spout has a thread formed on the outer peripheral wall surface of the spout so as to be screwed into the cap. In addition, some of the spout screws have a drain slit formed therein, and the role of the drain slit is to fill the pouch with contents and close the opening with a cap, as described in Patent Document 2. After closing, the product may be placed in a retort (autoclave) and sterilized by heat, such as in a hot water bath. Retorting allows water that has entered between the spout and the cap to flow downward through the drain slit. It is.
通常、スパウトはキャップと螺合しあうことで封鎖することができるが、特許文献３に記載のヒンジキャップ付き包装体は、ヒンジキャップの本体部に、抽出口部（スパウト）の外周面に形成した環状突部と係合するための突条を内側面に備えており、当該突条が前記環状突部を乗り越えることで、前記本体部が前記抽出口に打栓できるものとして考案されている。 Normally, a spout can be sealed by screwing together with a cap, but in the package with a hinge cap described in Patent Document 3, a spout is formed on the main body of the hinge cap and on the outer peripheral surface of the spout. The inner surface is provided with a protrusion for engaging with the annular protrusion, and the main body can be plugged into the extraction port by the protrusion passing over the annular protrusion. .
しかし、特許文献３に記載のヒンジキャップ付き包装袋では、レトルト（加圧滅菌用釜）に入れ、湯煎などの加熱殺菌を行った場合、ヒンジキャップと抽出口部（スパウト）の樹脂が加熱を加えたことにより収縮が発生し、ヒンジキャップの内側にはネジを有していないため、ヒンジキャップが前記抽出口部上で、クルクルと回ってしまう現象が発生しまう。すなわち、パウチ容器の印刷を施した正面側に、ヒンジキャップのツバが正面を向くように前記抽出口（スパウト）へ前記本体部を打栓してセットしても、加熱殺菌することでパウチ容器の正面側に前記ツバが向かず、横回転方向に位置ずれてしまう問題が発生していた。 However, in the packaging bag with a hinge cap described in Patent Document 3, when it is placed in a retort (autoclave) and heat sterilized using a hot water bath, the resin in the hinge cap and the extraction opening (spout) is heated. This causes contraction, and since there is no screw on the inside of the hinge cap, a phenomenon occurs in which the hinge cap turns around and around on the extraction port. That is, even if the main body is plugged and set in the spout with the brim of the hinge cap facing forward on the printed front side of the pouch container, the pouch container can be sealed by heat sterilization. A problem has occurred in which the brim does not face the front side of the machine and is misaligned in the lateral rotation direction.
本発明の目的は、上記課題を解決し、水抜きスリットを形成したスパウトに、打栓して取り付けたヒンジキャップがレトルト（加圧滅菌用釜）や、湯煎などの加熱殺菌を行った場合でも、ヒンジキャップの横回転方向の位置ずれが生じないスパウト用ヒンジキャップを提供することである。 The purpose of the present invention is to solve the above-mentioned problems, and the hinged cap attached to the spout with a drainage slit can be used even when heat sterilized in a retort (autoclave) or hot water bath. An object of the present invention is to provide a hinge cap for a spout that does not cause displacement in the lateral rotation direction of the hinge cap.
請求項１に記載の発明は、筒状の外周側壁面に螺合のネジと環状の突部が形成され、前記ネジには水抜きスリットが設けられたスパウトの開口部に被せるヒンジキャップであって、前記ヒンジキャップ本体の側壁の内面には、前記水抜きスリットに嵌り込むように、少なくとも１つ以上の突出した第１リブを形成し、前記第１リブは、側面視において上端から下方に向けて緩やかなハの字を形成するとともに、側面視において前記第１リブの下端の端部は略Ｖの字を形成しており、前記略Ｖの字の左右対称となる端面の傾斜は、前記ネジの水抜きスリット側に設けた傾斜面と接する傾斜面であるスパウト用ヒンジキャップである。 The invention according to claim 1 is a hinge cap that is fitted over an opening of a spout in which a threaded screw and an annular protrusion are formed on a cylindrical outer peripheral wall surface, and the screw is provided with a drainage slit. At least one protruding first rib is formed on the inner surface of the side wall of the hinge cap main body so as to fit into the drain slit, and the first rib extends downward from the upper end in side view. The lower end of the first rib forms an approximately V-shape when viewed from the side, and the slope of the end surface is symmetrical to the left and right of the approximately V-shape. This is a hinge cap for a spout, which is an inclined surface that is in contact with an inclined surface provided on the drain slit side of the screw .
請求項２に記載の発明は、前記ヒンジキャップ本体の内面に、前記突部と係合する第２リブを形成したスパウト用ヒンジキャップである。 The invention according to claim 2 is a hinge cap for a spout, in which a second rib that engages with the protrusion is formed on the inner surface of the hinge cap main body.
水抜きスリットを形成したスパウトに、打栓して取り付けたヒンジキャップがレトルト（加圧滅菌用釜）や、湯煎などの加熱殺菌を行った場合でも、ヒンジキャップの横回転方向の位置ずれが生じないスパウト用ヒンジキャップを提供することである。 Even if a hinge cap that is plugged and attached to a spout with a water drainage slit is sterilized by heat, such as in a retort (autoclave) or a hot water bath, the position of the hinge cap may shift in the lateral rotation direction. The present invention is to provide a hinged cap for a spout.
図１に示すスパウト２は、筒状本体２ａの外周側壁面には、螺合のネジ２ｂと、前記ネジ２ｂの下端側に環状の突部２ｄが形成されている。前記ネジ２ｂには入りこんだ水を下方へ誘導するための水抜きスリット２ｃが複数個所に設けられている。前記水抜きスリット２ｃは、入りこんだ水を下方へ流し出すためのものであるので、前記水抜きスリット２ｃが設けられているネジ２ｂの上または下に形成されたネジ２ｂにも同様に、一通となるよう水抜きスリット２ｃが設けられている。 The spout 2 shown in FIG. 1 has a threaded screw 2b formed on the outer peripheral wall surface of a cylindrical main body 2a, and an annular protrusion 2d formed on the lower end side of the screw 2b. The screw 2b is provided with a plurality of drainage slits 2c for guiding water that has entered downward. Since the water drain slit 2c is for draining water that has entered downward, a screw 2b formed above or below the screw 2b where the water drain slit 2c is provided also has one thread. Drainage slits 2c are provided so that
また、図１または図２、図８に示すように、本発明のスパウト用ヒンジキャップ１は、本体１ｂと蓋体１ａがヒンジ部１ｃを介して連接しているヒンジキャップ１である。前記ヒンジキャップ１の側壁の内面には、前記水抜きスリット２ｃの溝に嵌り込むように、少なくとも１つ以上の突出したレールの構造を有する第１リブ１ｄが形成されている。前記第１リブ１ｄは、水抜きスリット２ｃが一通として形成されている通路数と、同じ本数、形成することが望ましいが、前記第１リブ１ｄが１つだけ形成しても、機能は発揮できるものである。 Further, as shown in FIG. 1, FIG. 2, or FIG. 8, the spout hinge cap 1 of the present invention is a hinge cap 1 in which a main body 1b and a lid body 1a are connected via a hinge portion 1c. A first rib 1d having a structure of at least one protruding rail is formed on the inner surface of the side wall of the hinge cap 1 so as to fit into the groove of the drain slit 2c. It is desirable to form the same number of first ribs 1d as the number of passages in which the drain slits 2c are formed, but the function can be achieved even if only one first rib 1d is formed. It is something.
更に、本発明のスパウト用ヒンジキャップ１には、前記ヒンジキャップの本体１ｂの内面に、前記スパウト２に形成した突部２ｄと係合する第２リブ１ｅを形成している。前記第２リブ１ｅの断面は図６に示すように、外方向に突出した直角三角形を形成した凸部を環状につながっていてもよく、また、環状につながっている前記第２リブ１ｅの一部を、部分的に形成しない箇所を設けても良い。 Furthermore, the spout hinge cap 1 of the present invention has a second rib 1e that engages with a protrusion 2d formed on the spout 2 on the inner surface of the main body 1b of the hinge cap. As shown in FIG. 6, the cross section of the second rib 1e may be formed by connecting convex portions in the form of a right triangle projecting outward in an annular manner. It is also possible to provide a portion where the portion is not formed.
図１に示す本発明のスパウト用ヒンジキャップ１をスパウト２の開口部２ｅへセットした状態を示したものを図３に示している。また図４は、図３に示す前記本体１ｂをＡ－Ａ’にカットした状態を示した端面図である。また、図５は図３を上からみた状態へ示す平面図である。更に、図６は図５のＢ－Ｂ’をカットした状態を示す端面図である。 FIG. 3 shows a state in which the spout hinge cap 1 of the present invention shown in FIG. 1 is set in the opening 2e of the spout 2. As shown in FIG. Further, FIG. 4 is an end view showing a state in which the main body 1b shown in FIG. 3 is cut along the line A-A'. 5 is a plan view of FIG. 3 viewed from above. Further, FIG. 6 is an end view taken along the line B-B' in FIG. 5.
図４または図６に示すように、ヒンジキャップ１とスパウト２を打栓でセットした時に、前記ヒンジキャップ１の側壁の内側に形成した第１リブ１ｄが、前記スパウト２のネジ２ｂ上に形成した前記水抜きスリット２ｃへ嵌り込み嵌着できるようになる。そのため、レトルト（加圧滅菌用釜）に入れ加熱殺菌をした時に生じるヒンジキャップやスパウトの樹脂の収縮が生じた場合であっても、前記第１リブ１ｄと前記水抜きスリット２ｃは互いに嵌り込んだ状態であるので、横回転方向の位置ずれが生じないスパウト用ヒンジキャップを提供することができる。 As shown in FIG. 4 or 6, when the hinge cap 1 and spout 2 are set with plugs, the first rib 1d formed on the inside of the side wall of the hinge cap 1 is formed on the screw 2b of the spout 2. It becomes possible to fit and fit into the water drain slit 2c. Therefore, even if the resin of the hinge cap or spout shrinks when heated and sterilized in a retort (autoclave), the first rib 1d and the drain slit 2c will fit into each other. Therefore, it is possible to provide a hinge cap for a spout that does not cause positional displacement in the lateral rotation direction.
また、図７は図５のＣ－Ｃ’をカットした状態を示す端面図であるが、図１及び図７に示すとおり、前記ヒンジキャップ１を前記スパウト２へ打栓して嵌め込んだ時に、前記突部２ｄを乗り越えることで前記第２リブ１ｅと前記突部２ｄが嵌着することで嵌め殺し作用となり、容易にスパウト２からヒンジキャップ１を取り外すことができなくなる。そのため、図示はしていないが、本発明のスパウト用ヒンジキャップに、不正開封防止用のタンパーバンドなどを本体１ｂと蓋体１ａの間に付加することで、店頭に陳列された場合でも、安心して消費者に商品を提供することができる包装袋として利用することができる。 7 is an end view showing a state cut along CC' in FIG. 5, and as shown in FIGS. 1 and 7, when the hinge cap 1 is plugged and fitted into the spout 2, By climbing over the protrusion 2d, the second rib 1e and the protrusion 2d fit together, resulting in a fitting effect, making it impossible to easily remove the hinge cap 1 from the spout 2. Therefore, although not shown in the drawings, by adding a tamper band or the like to prevent tampering between the main body 1b and the lid 1a to the spout hinge cap of the present invention, it can be safely displayed at a store. It can be used as a packaging bag that can provide products to consumers with care.
更に、図８及び図９では、前記第１リブ１ｄの形状を具体的に説明する。まず、図９は図８のＤ－Ｄ’位置をカットした端面図であり、第１リブ１ｄを正面からみた図である。前記第１リブ１ｄは上端から下端にかけて緩やかなハの字を形成していても良い。また、前記第１リブ１ｄの下端の端部は、略Ｖの字を形成しており、略Ｖの字の左右対称となる端面の傾斜は、ネジ２ｂの上端側の傾斜と面し接する傾斜を形成することで、お互いの面が滑り合い、スパウト２に形成した水抜きスリット２ｃに前記第１リブ１ｄが挿入しやすくなる。更に、前記ハの字を形状した前記第１リブ１ｄの側壁面が前記水抜きスリット２ｃへ押し込むことで、嵌り込むと抜けにくい構造となっている。 Furthermore, in FIGS. 8 and 9, the shape of the first rib 1d will be specifically explained. First, FIG. 9 is an end view taken along the line DD' in FIG. 8, and is a view of the first rib 1d viewed from the front. The first rib 1d may form a gentle V-shape from the upper end to the lower end. Further, the lower end of the first rib 1d forms a substantially V-shape, and the symmetrical end surface of the substantially V-shape has an inclination that faces and contacts the inclination of the upper end of the screw 2b. By forming these, their surfaces slide against each other, making it easier for the first rib 1d to be inserted into the drain slit 2c formed in the spout 2. Furthermore, the side wall surface of the first rib 1d having a V-shape is pushed into the drain slit 2c, so that it is difficult to come out once it is fitted.
本発明のスパウチ用ヒンジキャップ１を取り付けたパウチ容器に充填する内容物は、ゼリーや飲料、調味料などの液体やペースト状の食品や、シャンプーやボディーソープ、接着剤、化粧水などの日用品に利用することができる。 The contents to be filled into the pouch container to which the spout hinge cap 1 of the present invention is attached include liquid and pasty foods such as jelly, beverages, and seasonings, as well as daily necessities such as shampoo, body soap, adhesive, and lotion. can be used.
