Description

本発明は口栓付きパウチに関するものであり、さらに詳しくは優れたガスバリア性を有する口栓付きパウチに関するものである。   The present invention relates to a pouch with a stopper, and more particularly to a pouch with a stopper having excellent gas barrier properties.

近年、口栓付きパウチはゼリー飲料、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が、ほとんどのものは口栓がポリエチレン樹脂、ポリプロピレン樹脂などを使用した射出成形品の単体のものからなり、パウチ本体にはアルミニウム箔やガスバリアフィルムを積層した積層材料を用いて内容物の保存性を付与させている。しかし、口栓はガスバリア性を有していない為に酸素等を嫌う内容物が充填された場合、口栓部分から酸素等が侵入し、内容物の変色や品質劣化を起こしていた。これらの問題を改善する為に口栓の外面若しくは内面又は両面にガスバリア性薄膜を積層した口栓付きパウチが提案されている（例えば、特許文献１参照。）。
特開２００３−１９１９７０号公報 In recent years, pouches with caps 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. It consists of a single injection-molded product using polypropylene resin or the like, and the pouch body is provided with the storage stability of the contents using a laminated material in which an aluminum foil or a gas barrier film is laminated. However, since the plug does not have gas barrier properties, when contents that dislike oxygen or the like are filled, oxygen or the like enters from the plug portion, causing discoloration or quality deterioration of the contents. In order to improve these problems, a plug-attached pouch has been proposed in which a gas barrier thin film is laminated on the outer surface, the inner surface, or both surfaces of the plug (see, for example, Patent Document 1).
JP 2003-19970 A

しかし、前記提案されている口栓付きパウチでも、口栓の注出口の部分から酸素などのガスが侵入して内容物の品質に悪影響を与える問題が生じていた。   However, even the proposed pouch with a plug has a problem that gas such as oxygen enters from the spout of the plug and adversely affects the quality of the contents.

本発明の課題は、内容物を注出する迄は優れた品質保存機能を有し、内容物を取り出す時は容易に注出できる口栓付きのパウチを提供することにある。   An object of the present invention is to provide a pouch with a stopper that has an excellent quality storage function until the contents are poured out and can be easily poured out when the contents are taken out.

本発明の請求項１に係る発明は、底シール部の反対辺に上辺シール部を有し、両サイドにサイドシール部を有するパウチ本体の上辺シール部にスパウトとキャップからなる口栓を設けたパウチの口栓側の所定位置に、パウチ本体の横幅と同一長さで、所定の幅のイージーピール性テープがパウチ本体内に上辺シール部と平行に挿入され、パウチ本体の両側内面のシーラント層と所定幅で加熱、圧着されてなる横シール部を設けた口栓付きパウチにおいて、該パウチ本体がガスバリア性積層材料からなり、該横シール部が両サイドのサイドシール部の位置にシール強度３０Ｎ／１５ｍｍ以上の強シール部を有し、中間位置にシール強度３０Ｎ／１５ｍｍ未満の弱シール部を有するものからなることを特徴とする口栓付きパウチである。   In the invention according to claim 1 of the present invention, a spout and a cap made of a cap are provided on the upper side seal portion of the pouch body having the upper side seal portion on the opposite side of the bottom seal portion and the side seal portions on both sides. An easy peel tape of the same width as the width of the pouch body and a predetermined width is inserted in a predetermined position on the plug side of the pouch in the pouch body in parallel with the upper side seal portion, and a sealant layer on both inner surfaces of the pouch body. In the pouch with a stopper provided with a horizontal seal portion heated and pressure-bonded at a predetermined width, the pouch body is made of a gas barrier laminate material, and the horizontal seal portion has a seal strength of 30 N at the positions of the side seal portions on both sides. It is a pouch with a cap, characterized in that it has a strong seal portion of 15 mm or more and a weak seal portion with a seal strength of less than 30 N / 15 mm at an intermediate position.

本発明の口栓付きパウチは、底シール部の反対辺に上辺シール部を有し、両サイドにサイドシール部を有するパウチ本体の上辺シール部にスパウトとキャップからなる口栓を設けたパウチの口栓側の所定位置に、パウチ本体の横幅と同一長さで、所定の幅のイージーピール性テープがパウチ本体内に上辺シール部と平行に挿入され、パウチ本体の両側内面のシーラント層と所定幅で加熱、圧着されてなる横シール部を設けた口栓付きパウチにおいて、該パウチ本体がガスバリア性積層材料からなり、該横シール部が両サイドのサイドシール部の位置にシール強度３０Ｎ／１５ｍｍ以上の強シール部を有し、中間位置にシール強度３０Ｎ／１５ｍｍ未満の弱シール部を有するものからなるので、内容物を充填、密封した時は四方が底シール部、サイドシール部、横シール部で囲まれ、密封された状態であるので、優れた品質保持性を有し、内容物を注出する時は、横シール部の弱シール部の
部分を層間剥離して注出用流路を設け、その注出用流路を経由してスパウトから容易に注出できる。 The pouch with a spout of the present invention is a pouch having a spout and a cap formed of a spout and a cap on the top seal portion of the pouch body having a top seal portion on the opposite side of the bottom seal portion and side seal portions on both sides. An easy-peel tape of the same width as the width of the pouch body and a predetermined width is inserted into the pouch body in a predetermined position in parallel to the upper seal part, and the sealant layers on both inner surfaces of the pouch body In a pouch with a stopper provided with a lateral seal portion heated and pressure-bonded in width, the pouch body is made of a gas barrier laminate material, and the lateral seal portion has a seal strength of 30 N / 15 mm at the positions of the side seal portions on both sides. Since it has the above strong seal part and has a weak seal part with a seal strength of less than 30 N / 15 mm in the middle position, when filling and sealing the contents, the four sides are the bottom seal part, Since it is surrounded and sealed by the id seal part and the horizontal seal part, it has excellent quality retention, and when the contents are poured out, the weak seal part of the horizontal seal part is delaminated. An extraction channel is provided, and can be easily extracted from the spout via the extraction channel.
