Description

本発明は食品分野や医療分野等で使用される包装袋に装着するスパウトに関するものである。   The present invention relates to a spout attached to a packaging bag used in the food field, the medical field, and the like.

近年、キャップとスパウトからなる口栓を備えた包装袋はゼリー飲料、清涼飲料、練り製品などの食品分野や、トイレタリー用品分野、栄養剤や流動食などの医療分野で広く使用されている。通常、包装袋に口栓を装着する時は、包装袋の内面と口栓のスパウトに設けられた取付部を熱シールして接着させているが、取付部の形状が舟形状の場合、中心より外側の先端部分でシール不良が発生することが多く、その場合シール不良部分から内容物が外に漏れ出すなどの問題が生じていた。シール不良を発生させない為の一方法として、シール温度及びシール圧力を高くし、シール時間を長くする方法があるが、この場合過度の熱量がかかって、接着部分に皺、変形が発生したり、冷却時間が長くなって効率が悪くなったり、さらに取付部の底面にシール時の取付部の溶融樹脂塊ができて、包装袋に溶融樹脂塊に起因するピンホール等を発生させていた。これらの問題点を改善したスパウトを装着した袋が提案されている（例えば、特許文献１参照。）。
特開平１０−１２９６８９号公報 In recent years, packaging bags having caps and spouts have been widely used in food fields such as jelly drinks, soft drinks, and paste products, toiletries, and medical fields such as nutrients and liquid foods. Normally, when a cap is attached to a packaging bag, the inner surface of the packaging bag and the mounting portion provided on the spout of the plug are heat sealed and bonded. In many cases, a seal failure often occurs at the tip portion on the outer side. In such a case, problems such as leakage of contents from the seal failure portion have occurred. One way to prevent defective seals is to increase the sealing temperature and pressure, and lengthen the sealing time. In this case, excessive heat is applied, and the adhesive part is wrinkled and deformed. The cooling time is prolonged and the efficiency is deteriorated. Further, a molten resin lump of the mounting portion at the time of sealing is formed on the bottom surface of the mounting portion, and a pinhole or the like due to the molten resin lump is generated in the packaging bag. A bag equipped with a spout that has improved these problems has been proposed (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-129689

以下に、取付部（２０、２０′）について図面に沿って詳細に説明すると図３（ａ）は図１（ａ）はのＡ−Ａ線断面図であり、取付部（２０）は、中空管部（１０）の下端と同内径の円形の空間（１６）を有し、さらに高さ方向に貫通した孔部（３０、３１、３２、３３、３４、３５、３６、３７）を有し、前後が鋭角になっている所定高さの舟形状のものからなる本体部（２１）の前後両端に、厚さ（ｄ1）が０．３〜１ｍｍの平板からなり、上端の幅が幅（ｄ3）で本体部の下端方向に向かって幅が狭くなっている薄肉部（２４、２５）を有しており、（ｂ）は図２（ａ）のＡ−Ａ線断面図であり、取付部（２０′）は中空管部（１０′）の下端と同内径の円形の空間（１６′）を有し、さらに高さ方向に貫通した孔部（３０′、３１′、３２′、３３′、３４′、３５′、３６′、３７′）を有し、前後が鋭角になっている所定高さの舟形状のものからなる本体部（２１′）の前後両端に、同一の幅（ｄ3）で、上端の厚さ（ｄ1）が０．５〜１ｍｍで下端の厚さ（ｄ2）が０．３〜０．４ｍｍになっている薄肉部（２４′、２５′）を有している。 Hereinafter, the mounting portion (20, 20 ') will be described in detail with reference to the drawings. FIG. 3 (a) is a cross-sectional view taken along line AA of FIG. 1 (a), and the mounting portion (20) It has a circular space (16) having the same inner diameter as the lower end of the hollow pipe (10), and further has holes (30, 31, 32, 33, 34, 35, 36, 37) penetrating in the height direction. The front and rear ends of the boat-shaped body portion 21 having a predetermined height with acute angles at the front and rear are made of flat plates with a thickness (d 1 ) of 0.3 to 1 mm, and the width of the upper end is It has a thin portion (24, 25) having a width (d 3 ) that is narrower toward the lower end of the main body, and (b) is a cross-sectional view taken along line AA in FIG. The mounting portion (20 ') has a circular space (16') having the same inner diameter as the lower end of the hollow tube portion (10 '), and further has holes (30', 31 'penetrating in the height direction). 32 ', 33', 34 ', 35', 36 ', 37') at the front and rear ends of the body portion (21 ') made of a boat-shaped body having a predetermined height with acute angles at the front and rear, A thin part (24 ′, 24 ′, having the same width (d 3 ), an upper end thickness (d 1 ) of 0.5 to 1 mm and a lower end thickness (d 2 ) of 0.3 to 0.4 mm. 25 ').

図４（ａ）は図１（ａ）のＢ−Ｂ線断面図であり、取付部（２０）は高さ方向に同一厚みで、その厚さ（ｄ1）は０．３〜１ｍｍの範囲であり、（ｂ）は図２（ａ）のＢ−Ｂ線断面図であり、上端の厚さ（ｄ1）が０．５〜１ｍｍで、下端の厚さ（ｄ2）が０．３〜０．４ｍｍである。前記厚さ（ｄ1）が１ｍｍを越えると溶融樹脂塊が出来やすくなり、厚さ（ｄ2）が０．３ｍｍ未満になると強度的に不足になり良くない。 4A is a cross-sectional view taken along the line BB of FIG. 1A, and the mounting portion 20 has the same thickness in the height direction, and the thickness (d 1 ) is in the range of 0.3 to 1 mm. FIG. 2B is a cross-sectional view taken along the line BB in FIG. 2A, where the upper end thickness (d 1 ) is 0.5 to 1 mm and the lower end thickness (d 2 ) is 0.3. ~ 0.4 mm. When the thickness (d 1 ) exceeds 1 mm, a molten resin lump is likely to be formed, and when the thickness (d 2 ) is less than 0.3 mm, the strength is insufficient.

本発明のスパウトは、取付部（２０、２０′）が前記記載のような構造になっているので、包装袋に熱シールして装着する時に、各種シール条件を高くしなくても、袋の内面と薄肉部（２４、２４′、２５、２５′）が強固に接着され、また先端部分にシール不良が発生しない。従って、スパウトを装着した包装袋は落下しても装着部分から破れることがなく、また薄肉部（２４、２４′、２５、２５′）の下端に溶融樹脂塊が発生せず、包装袋に溶融樹脂塊に起因するピンホールなどを発生させない。   In the spout of the present invention, the mounting portion (20, 20 ') has the structure as described above. The inner surface and the thin portion (24, 24 ', 25, 25') are firmly bonded, and no sealing failure occurs at the tip portion. Therefore, even if the packaging bag with the spout is dropped, it will not be broken from the mounting part, and no molten resin lump will be generated at the lower end of the thin part (24, 24 ', 25, 25'), so Does not generate pinholes due to resin mass.

本発明のスパウト（１、１′）はポリエチレン樹脂、ポリプロピレン樹脂等のポリオレフィン系樹脂からなっている。   The spout (1, 1 ') of the present invention is made of a polyolefin resin such as polyethylene resin or polypropylene resin.
