【発明の属する技術分野】
本発明は、液状、ゼリー状等内容物を注出する容器用の合成樹脂製注出口に関するものであり、さらに詳細には、樹脂量を極力少なくして環境に配慮した合成樹脂製注出口の形状に関する。
【０００２】
【従来の技術】
従来、液状の清涼飲料やゼリー状の飲料（栄養剤も含む）などの包装容器として、プラスチックフィルムを主体とした軟包装袋や紙を主体とした紙容器があり、これら容器に前記飲料等を注ぎ出す合成樹脂製の注出口が溶着されている注出口付容器が知られ、上記飲料に限らず、液体洗剤やシャンプー等トイレタリー用などにも広く普及している。
【０００３】
上記容器用の合成樹脂製注出口は、チューブ状の注出用筒体の下部に容器（軟包装袋等）の開口部がシールされるための容器用溶着部があり、この容器用溶着部は容器の安定したシール性と、さらに材料コストとともに廃棄物の減量や省資源（石油資源）に配慮して極力この樹脂量を少なくするようにしたもので、例えば図３（ａ）の正面図に示すように、チューブ状の注出用筒体（２０）の上部にはキャップ螺着用のネジ山（２２）を備え、下部にはそれぞれの間に空間（Ｓ）を設けた４枚の容器用溶着板（１０）が水平に一体化されて、この容器用溶着板（１０）は、図３（ｂ）の上面図に示すように、左右端（１０ａ、１０ｂ）に尖端を有する（左右端部が尖っている）舟形状でなり、この容器用溶着板（１０）が薄い（１ｍｍ程度）のでこれらを支えて容器とのシール性をよく（安定して）するためその左右端（１０ａ、１０ｂ）から注出用筒体（２０）まで延びて、この注出用筒体（２０）と一体化される板状リブ（１２）で上記４枚の容器用溶着板（１０）を連結一体化せしめている合成樹脂製注出口（２）があった。
【０００４】
しかし、上記板状リブ（１２）で４枚の容器用溶着板（１０）を連結一体化せしめている合成樹脂製注出口（２）では、この板状リブ（１２）が各容器用溶着板（１０）間の空間（Ｓ）いっぱいにあり、そのため多くの樹脂量を必要とし、材料コストが嵩むことと、樹脂が肉厚となり収縮による「ひけ」が生じること、および使用後の廃棄と樹脂資源に配慮されていないという環境に係わる問題があった。
上記「ひけ」とは、合成樹脂はそれぞれ固有の成形収縮率によって縮むに、中心部や肉圧部などの冷却が遅れた部分の収縮によって表面が引っ張られて凹む現象をいう。
【０００５】
また、上記容器用の合成樹脂製注出口の一事例として、例えば図４（ａ）の正面図に示すように、チューブ状の注出用筒体（２０）の上部にはキャップ螺着用のネジ山（２２）を備え、下部には容器のシール性をよく（安定して）するため４枚の厚手（２ｍｍ程度）の容器用溶着板（１１）が水平に一体化されていて、それぞれの間に狭い（１ｍｍ程度）空間（Ｓ）を設けたもので、この厚手の容器用溶着板（１１）は、図４（ｂ）の上面図に示すように、左右端（１１ａ、１１ｂ）に尖端を有する（左右端部が尖っている）舟形状でなり、その左右端（１１ａ、１１ｂ）で４枚の厚手の容器用溶着板（１１）が連結一体化されている合成樹脂製注出口（３）があった。
【０００６】
しかし、上記厚手の容器用溶着板（１１）で一体化されている合成樹脂製注出口（３）では、シール性は極安定しているが容器用溶着板（１１）自体が多くの樹脂量を必要とし、上記図３（ａ）に示す上記板状リブ（１２）で容器用溶着板（１０）を連結している合成樹脂製注出口（２）と同様に材料コストが嵩むことと、樹脂が肉厚となり収縮による「ひけ」を生じること、および使用後の廃棄と省資源に配慮されていないという環境に係わる問題があった。
【０００７】
【発明が解決しようとする課題】
本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、安定した容器とのシール性を保持しつつ、材料コストが嵩まず、ひけが発生せず、かつ使用後の廃棄物や省資源に係わる環境に配慮された合成樹脂製注出口およびそれを備えた合成樹脂製注出口付容器を提供することにある。
【０００８】
【課題を解決するための手段】
本発明に於いて上記課題を達成するために、まず請求項１の発明では、注出用筒体の下部に複数枚の左右端に尖端を有する舟形状の容器用溶着板が一体となって水平に取り付けられ、それら容器用溶着板の間を板状縦リブで連結一体化している合成樹脂製注出口であって、前記板状縦リブによる連結一体化が複数枚の容器用溶着板の左右端の尖端のみであることを特徴とする合成樹脂製注出口としたものである。
【０００９】
上記請求項１の発明によれば、注出用筒体の下部に複数枚の舟形状の容器用溶着板が水平に一体化され、その左右端の尖端のみで各容器用溶着板を連結一体化されているので、従来のように厚手の容器用溶着板でなくても安定した容器とのシール性を保持することができ、かつ従来のように各容器用溶着板間の空間いっぱいに連結用の板状リブを必要としないので、使用する樹脂量を少なくすることができ、よって材料コストの節減とともに、樹脂の冷却効率がよく「ひけ」が発生せず、かつ使用後の廃棄物の減量化や省資源に貢献する合成樹脂製注出口を提供できる。
【００１０】
また、請求項２の発明では、上記請求項１に記載の合成樹脂製注出口を装備している合成樹脂製注出口付容器としたものである。
【００１１】
上記請求項２の発明によれば、上記請求項１に記載の合成樹脂製注出口を装備している合成樹脂製注出口付容器とすることによって、この合成樹脂製注出口と容器とのシール性が保持され、「ひけ」が発生せず、かつ使用樹脂量を少なくして使用後の廃棄物の減量化や省資源に貢献し環境問題に配慮された容器用合成樹脂製注出口付容器を提供できる。
【００１２】
【発明の実施の形態】
以下本発明の実施の形態を図面を用いて詳細に説明する。
【００１３】
本発明は、図１の斜視図に示すように、例えば液状、ゼリー状等内容物を注出するための合成樹脂製注出口（１）と、それと一体化されている４枚の舟形状の容器用溶着板（１０）の端縁にプラスチックフィルムを主体としたパウチ（５）の上縁開口部（５ａ）がシールされている合成樹脂製注出口付容器（１００）に関するもので、特に、使用する樹脂量を極力少なくして廃棄物や省資源に係る環境に配慮された合成樹脂製注出口（１）の形状に関するものである。
【００１４】
そこで上記請求項１に係る発明は、例えば図２（ａ）の正面図に示すように、注出用筒体（２０）の下部に４枚の容器用溶着板（１０）が一体となって水平に取り付けられていて、この容器用溶着板（１０）は、図２（ｂ）の上面図に示すように、左右端（１０ａ、１０ｂ）に尖端を有する舟形状の容器用溶着板（１０）でなり、この４枚の容器用溶着板（１０）の連結一体化を、図２（ａ）および図２（ｂ）に示すように、左右端（１０ａ、１０ｂ）の尖端のみに設けた板状縦リブ（１４）で成されている合成樹脂製注出口（１）としたものである。
【００１５】
このように４枚の容器用溶着板（１０）の連結一体化が、左右端（１０ａ、１０ｂ）の尖端のみに設けた板状縦リブ（１４）で成されているので、図６（ａ）に示す従来の板状リブ（１２）のように、各容器用溶着板（１０）間の空間（Ｓ）いっぱいになく、そのため使用する樹脂量が少なくなり、よって材料コストが低減され、かつ環境に配慮された合成樹脂製注出口（１）とすることができ、さらに図７（ａ）に示す従来の厚手の容器用溶着板（１１）に比べ、図２（ａ）および図２（ｂ）に示すように、４枚の容器用溶着板（１０）の連結一体化が、左右端（１０ａ、１０ｂ）の尖端のみに設けた板状縦リブ（１４）で成されているので、樹脂量の少ない薄い容器用溶着板（１０）としても安全性の高いシール性が得られる合成樹脂製注出口（１）とするものである。
【００１６】
また、上記請求項２に係る発明では、図１に示すように、例えばチューブ状の注出用筒体（２０）の下部に４枚の舟形状の容器用溶着板（１０）が一体となって水平に取り付けられている合成樹脂製注出口（１）て、この各容器用溶着板（１０）の端縁に、フィルムを主体としたパウチ（５）の上端開口部がシールされている合成樹脂製注出口付容器（１００）とするものである。
【００１７】
上記フィルムを主体としたパウチ（５）に替え、図示しないが、例えば紙製容器（カートン）とすることもでき、内容物によってその容器を適宜選定することができる。
【００１８】
上記本発明の合成樹脂製注出口（１）としては、その材料としてポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ナイロンなどの汎用樹脂が挙げられ、内容物や用途等に応じて適宜選定され、これら樹脂の射出成形法等公知の成形法によって得られる。
【００１９】
また、上記合成樹脂製注出口（１）のサイズは、それにシールされる容器のサイズや内容物によって異なるが、例えば清涼飲料用の合成樹脂製注出口の場合、図２（ａ）および図２（ｂ）に示すように、この注出用筒体（２０）の外径（Ｋ）が２０ｍｍ程度、その長さ（Ｌ１）が３０ｍｍ程度、さらに容器用溶着板（１０）の左右端（１０ａ、１０ｂ）の長さ（Ｌ２）が４１ｍｍ程度のものが一般的であり、この時の容器用溶着板（１０）の厚さ（Ｄ）は１ｍｍ程度、それらの間隔（Ｈ）は２ｍｍ程度で、これらを連結一体化している板状縦リブ（１４）の幅（Ｗ）は、容器用溶着板（１０）の左右端（１０ａ、１０ｂ）を中心として左右に３ｍｍ延びた６ｍｍ程度とし、このように厚さ（Ｄ）のない容器用溶着板（１０）と幅（Ｗ）のない板状縦リブ（１４）とし、合成樹脂製注出口（１）に使用する樹脂量を極力少なくしても安定した容器とのシール性を保持する合成樹脂製注出口（１）とすることができる。
【００２０】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。
即ち、上記請求項１に係る発明においては、注出用筒体の下部に複数枚の左右端に尖端を有する舟形状の容器用溶着板が一体となって水平に取り付けられ、それら容器用溶着板の間を板状縦リブで連結一体化している合成樹脂製注出口において、その板状縦リブによる連結一体化が左右端の尖端のみとしているので、従来のように厚手の容器用溶着板でなくても安定した容器とのシール性を保持することができ、かつ従来のように各容器用溶着板間の空間には連結用の板状リブを必要としないので、使用する樹脂量を少なくすることができ、よって材料コストの節減とともに、「ひけ」が発生せず、かつ使用後の廃棄物の減量化や省資源に貢献する合成樹脂製注出口を提供できる効果がある。
【００２１】
また、上記請求項２に係る発明においては、上記請求項１に記載の合成樹脂製注出口を装備している合成樹脂製注出口付容器とすることによって、この合成樹脂製注出口と容器とのシール性が保持され、かつ使用樹脂量を少なくして使用後の廃棄物の減量化や省資源に貢献し環境問題に配慮された容器用合成樹脂製注出口付容器を提供できる効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a synthetic resin spout for containers for discharging contents such as liquid and jelly-like, and more particularly, to an environment-friendly synthetic resin spout for minimizing the amount of resin. Regarding the shape.
[0002]
[Prior art]
BACKGROUND ART Conventionally, as packaging containers for liquid soft drinks and jelly-like beverages (including nutrients), there are soft packaging bags mainly composed of plastic films and paper containers mainly composed of paper. A container with a spout to which a spout made of a synthetic resin to be poured out is welded is known, and is widely used not only for the above-mentioned drinks but also for toiletries such as liquid detergents and shampoos.
[0003]
The synthetic resin pouring port for the container has a container welding portion for sealing an opening of a container (a soft packaging bag or the like) at a lower portion of a tubular pouring cylinder, and the container welding portion. Fig. 3 (a) is a view in which the amount of resin is reduced as much as possible in consideration of the stable sealing properties of the container, the material cost, and the reduction of waste and resource saving (oil resources). As shown in the figure, four containers each having a thread (22) for attaching a cap screw at an upper part of a tubular pouring cylinder (20) and a space (S) between them at a lower part. The welding plate (10) for a container is horizontally integrated, and the welding plate (10) for a container has a point at the left and right ends (10a, 10b) as shown in the top view of FIG. It has a boat shape (pointed end), and the welding plate (10) for this container is thin (about 1 mm) In order to support them and improve (stable) the sealing property with the container, they extend from the left and right ends (10a, 10b) to the pouring cylinder (20), and are connected to the pouring cylinder (20). There was a synthetic resin spout (2) in which the above-mentioned four container welding plates (10) were connected and integrated by the integrated plate-like ribs (12).
[0004]
However, in the synthetic resin spout (2) in which the four plate welding plates (10) are connected and integrated by the plate-like ribs (12), the plate-like ribs (12) are connected to each of the container welding plates. The space (S) between (10) is full, so that a large amount of resin is required, the material cost increases, the resin becomes thick and "shrinkage" occurs due to shrinkage, and disposal and resin after use There was a problem with the environment that resources were not considered.
The above-mentioned “shrinkage” refers to a phenomenon in which the synthetic resin shrinks at a specific molding shrinkage rate, and the surface is pulled and dented due to shrinkage of a portion where cooling is delayed, such as a central portion or a pressure portion.
[0005]
Further, as an example of the synthetic resin spout for the container, as shown in the front view of FIG. 4 (a), a screw with a cap screw is attached to the upper part of the tube-shaped spout cylinder (20). A mountain (22) is provided, and four thick (about 2 mm) container welding plates (11) are horizontally integrated at the lower part to improve (stable) the sealing property of the container. A thin (about 1 mm) space (S) is provided between the thick container welding plates (11) at the left and right ends (11a, 11b) as shown in the top view of FIG. 4 (b). A synthetic resin spout having a pointed (both right and left ends) boat-like shape and four thick container welding plates (11) connected and integrated at the left and right ends (11a, 11b). There was (3).
[0006]
However, in the synthetic resin spout (3) integrated with the thick container welding plate (11), the sealing property is extremely stable, but the container welding plate (11) itself has a large amount of resin. And the material cost is increased in the same manner as the synthetic resin spout (2) connecting the welding plate (10) for the container with the plate-like rib (12) shown in FIG. There are problems related to the environment that the resin becomes thick and causes shrinkage due to shrinkage and that disposal and resource saving after use are not considered.
[0007]
[Problems to be solved by the invention]
The present invention has been made to solve the problems of the related art, and has as its object to maintain a stable sealing property with a container, not to increase the material cost, to prevent sink marks, and to be used.

And a spout made of a synthetic resin, characterized in that the spout is only the tip of the spout.
[0009]
According to the first aspect of the present invention, a plurality of boat-shaped container welding plates are horizontally integrated at the lower part of the pouring cylinder, and the respective container welding plates are connected and integrated only at the left and right ends. It is possible to maintain stable sealing with containers even if it is not a thick welding plate for containers as in the past, and to connect the entire space between the welding plates for each container as in the past. Since no plate-shaped ribs are required, the amount of resin used can be reduced, thereby reducing material costs, improving the cooling efficiency of the resin, preventing the occurrence of sink marks, and reducing the amount of waste after use. It can provide a synthetic resin spout that contributes to weight reduction and resource saving.
[0010]
According to a second aspect of the present invention, there is provided a container with a synthetic resin spout provided with the synthetic resin spout according to the first aspect.
[0011]
