When administering the filled liquid food, the supply tube can be connected to the spout attached to the pouch for simple and hygienic administration to the patient, etc. Alternatively, even when drinking water is administered using the pouch after the liquid food is administered, the diluent or drinking water can be easily injected from the liquid inlet provided on the top of the pouch, and hygienically. The present invention relates to a pouch with a spout that can be administered.

従来、流動食を密封包装し、流動食を患者等に投与する際には、パウチに取り付けられた注出口に供給チューブを連結して、簡便且つ衛生的に投与することができ、また、投与前に流動食の濃度調整などが必要な場合、或いは、流動食の投与後、飲料水などをそのパウチを利用して投与する場合に、パウチの上部に設けられた液体注入口から希釈液や飲料水などを注入し衛生的に患者等に投与することのできる流動食用の注出口付きパウチとしては、例えば、（１）パウチ本体を左右両側にガセット部を設けたガセットパウチ形式で形成し、パウチの下部にプラスチックの成形体によるキャップ付きなどの注出口を取り付け、パウチの上部には、一方のコーナー部に液体注入口を形成するための開封手段を設けると共に、その下側に開封した液体注入口を閉じるための横方向の折り曲げ予定線を設け、また、パウチ上部の中央部には、前記折り曲げ予定線の上下に略対称形で広がるように広幅のヒートシール部を設け、前記折り曲げ予定線でパウチを折り曲げた時、前記広幅のヒートシール部の領域内で互いに重なり合う位置にパウチの吊り下げ用と再封手段を兼ねた切り目線による穴を設けて、その重なり合った穴をスタンドのフックなどに掛ける方法で、開封した液体注入口を再封するようにした流動食用の注出口付きパウチがある（例えば、特許文献１参照）。   Conventionally, liquid food is sealed and packaged, and when liquid food is administered to a patient or the like, a supply tube can be connected to a spout attached to a pouch, which can be administered simply and hygienically. When it is necessary to adjust the concentration of the liquid food before, or when the drinking water is administered using the pouch after administration of the liquid food, the diluted liquid or the like can be obtained from the liquid inlet provided at the top of the pouch. As a pouch with a spout for liquid food that can be infused with drinking water etc. and hygienically administered to patients, for example, (1) the pouch body is formed in a gusset pouch format with gusset portions on the left and right sides, A spout such as a plastic molded cap is attached to the lower part of the pouch, and the upper part of the pouch is provided with an opening means for forming a liquid inlet at one corner, and the lower part thereof is opened. A horizontal fold line for closing the body injection port is provided, and a wide heat seal portion is provided at the center of the upper part of the pouch so as to spread substantially symmetrically above and below the fold line. When the pouch is folded along the planned line, a hole is formed by a score line that serves as both a pouch suspension and a resealing means in the region where the wide heat seal portion overlaps, and the overlapping hole is formed on the stand. There is a pouch with a spout for liquid food in which the opened liquid injection port is resealed by a method of hanging on a hook or the like (see, for example, Patent Document 1).

また、（２）パウチ本体を、前後２面の壁面フィルムの上部と下部の間に、それぞれ状面フィルムまたは底面フィルムを内側に折り込んで挿入し、周囲の端縁部をヒートシールしてなる上下にガセット部を有する形式で形成し、下部のガセット部の前後のひだ状部のうち、一方のひだ状部にプラスチックの成形体よりなるキャップ付きなどの注出口を取り付けると共に、上部のガセット部の前後のひだ状部のうち、一方のひだ状部は上方に延長してその延長部にパウチの吊り下げ手段を設け、もう一方のひだ状部には、液体注入口を設けるため、その上部から下方に、上部の端縁部を封止する注入口上部シール部、切り取り線、ジッパー形式のファスナーを順に設けて液体注入口を開封した後、ジッパー形式のファスナーで再封できるようにした流動食用の注出口付きパウチがある（例えば、特許文献２参照）。

JP 2001-199457 A (2nd to 5th pages, FIGS. 1 to 4) JP-A-2001-213451 (2nd to 4th pages, FIGS. 1 to 4)

前記（１）に記載した流動食用の注出口付きパウチによれば、パウチに充填された流動食を患者等に投与する際、注出口を開封してその口部に供給チューブを連結し、パウチ上部に設けられた吊り下げ用の穴を、例えばスタンドのフックに掛けてパウチを吊り下げることにより、スムーズに且つ衛生的に流動食を患者等に投与することができる。
また、最初に流動食の希釈など濃度調整が必要な場合、或いは、流動食の投与後、そのパウチを利用して飲料水などを患者等に投与する場合は、パウチ上部のコーナー部に設けられた開封手段により液体注入口を開封し、ガセット部の側面フィルムを外側に引き出すことにより、液体注入口が開口するので、この部分から希釈液や飲料水等を注入することができる。希釈液や飲料水等を注入した後は、パウチをスタンドのフックから取り外して前記外側に引き出した側面フィルムを内側に折り戻して、折り曲げ予定線でパウチ上部を一方に折り返すことにより、開封された液体注入口が閉鎖されると共に、上下の吊り下げ用と再封手段を兼ねた切り目線による穴が重なり合うので、再度、重なり合った穴をスタンドのフックに掛けてパウチを吊り下げる方法で、流動食または飲料水等を衛生的に患者等に投与することができる。 According to the pouch with a spout for liquid food described in the above (1), when the liquid food filled in the pouch is administered to a patient or the like, the spout is opened and a supply tube is connected to the mouth of the pouch. For example, by hanging a pouch by hanging a suspension hole provided in the upper part on a hook of a stand, a liquid food can be smoothly and hygienically administered to a patient or the like.
In addition, when it is necessary to adjust the concentration first, such as dilution of liquid food, or when drinking water is administered to a patient etc. using the pouch after administration of the liquid food, it is provided at the corner portion at the top of the pouch. The liquid inlet is opened by the unsealing means and the side film of the gusset portion is pulled out to open the liquid inlet, so that a diluent, drinking water, etc. can be injected from this portion. After injecting dilution liquid, drinking water, etc., the pouch was removed from the hook of the stand, the side film pulled out to the outside was folded back inward, and the upper part of the pouch was folded back to one side along the planned folding line. As the liquid inlet is closed, the holes by the cut lines that serve as the top and bottom suspension and reseal means overlap. Or drinking water etc. can be administered to a patient etc. hygienically.

しかし、このような流動食用の注出口付きパウチでも、液体注入口を開口させた時、開口部が比較的狭い上、パウチのフィルムが柔軟性材料であるため、開口部が安定しにくく、液体の注入操作が厄介になる問題があり、また、開封した液体注入口を再封する際にも、吊り下げたパウチをスタンドのフックから一旦取り外して、折り曲げ予定線でパウチの上部を一方に折り返して重なり合った吊り下げ用と再封手段を兼ねた穴を、再度スタンドのフックに掛けて吊り下げる必要があり、特に病院等で多数の流動食用の注出口付きパウチを扱う場合には、再封の操作も煩わしいという問題があった。   However, even in such a pouch with a spout for liquid food, when the liquid inlet is opened, the opening is relatively narrow, and the film of the pouch is a flexible material. In addition, when resealing the opened liquid inlet, once remove the suspended pouch from the hook of the stand and fold the upper part of the pouch to the other side along the planned folding line. It is necessary to hang the overlapping holes and the re-sealing holes again on the stand hooks, especially when handling a large number of pouches with pouring spouts for liquid food in hospitals. There was a problem that the operation of was troublesome.

前記（２）に記載した吊り下げ式パウチでは、パウチの上下にガセット部を設け、下部のガセット部の一方のひだ状部に注出口を取り付けると共に、上部のガセット部には、一方のひだ状部にパウチの吊り下げ手段を設け、もう一方のひだ状部には液体注入口を設けるため、上部の端縁部をヒートシールする上部シール部の下に開封手段を設け、更にその下にジッパー形式のファスナーを設けた構成としている。
従って、この吊り下げ式パウチに流動食を密封包装し、その流動食を患者等に投与する際には、前記（１）に記載した流動食用の注出口付きパウチと同様に、注出口を開封してその口部に供給チューブを連結し、パウチ上部に設けられた吊り下げ手段（フック穴）を、例えばスタンドのフックに掛けてパウチを吊り下げることにより、スムーズに且つ衛生的に流動食を患者等に投与することができる。
また、最初に流動食の希釈など濃度調整が必要な場合、或いは、流動食の投与後、そのパウチを利用して飲料水などを患者等に投与する場合は、パウチ上部のガセット部の一方のひだ状部に設けられた液体注入口を、その上部シール部をその下に設けられた開封手段で切り取って開封した後、ジッパー形式のファスナーの嵌合を解離させることにより開口させることができるので、その開口部から比較的容易に希釈液や飲料水などを注入することができる。希釈液や飲料水などを注入した後は、ジッパー形式のファスナーを嵌合させることにより、開口させた液体注入口を再封することができる。この間の一連の操作は、パウチをスタンドのフックに吊り下げたままで行えるのでその操作性には優れている。 In the hanging type pouch described in the above (2), a gusset portion is provided at the top and bottom of the pouch, and a spout is attached to one pleat portion of the lower gusset portion, and one pleat shape is attached to the upper gusset portion. In order to provide a pouch suspending means in the part and a liquid inlet in the other pleated part, an opening means is provided under the upper seal part for heat-sealing the upper edge, and a zipper is provided below The structure is provided with a type fastener.
Therefore, when the liquid food is sealed and packaged in this hanging pouch and the liquid food is administered to a patient or the like, the spout is opened in the same manner as the pouch with a spout for liquid food described in (1) above. Then, the supply tube is connected to the mouth portion, and the suspension means (hook hole) provided at the upper part of the pouch is hung on the hook of the stand, for example, and the pouch is suspended, so that the liquid food can be smoothly and sanitized. It can be administered to patients and the like.
In addition, when concentration adjustment is necessary, such as dilution of liquid food, or when drinking water is administered to a patient using the pouch after administration of liquid food, one of the gussets above the pouch Since the liquid inlet provided in the pleated part can be opened by cutting off the upper seal part with the opening means provided thereunder and then opening the zipper-type fastener by disengaging it. A diluent, drinking water or the like can be injected relatively easily from the opening. After injecting a diluent or drinking water, the opened liquid injection port can be resealed by fitting a zipper-type fastener. Since a series of operations during this time can be performed with the pouch suspended from the stand hook, the operability is excellent.

しかし、このような吊り下げ式パウチでも、パウチの上下両方にガセット部を設け、下部のガセット部の一方のひだ状部には注出口を取り付け、上部のガセット部には、一方のひだ状部に吊り下げ手段を設け、もう一方のひだ状部には、液体注入口を設けるため上部の端縁部を上部シール部でヒートシールし、その下に開封手段を設け、更にその下に再封手段としてジッパー形式のファスナーを設けているので、機能性には優れるものの製造工程が煩雑になり生産性に劣り、特に液体注入口の再封手段としてのジッパー形式のファスナーは、コストアップの要因を増し、全体として生産性と経済性に劣る問題があった。   However, even in such a hanging type pouch, a gusset portion is provided on both the upper and lower sides of the pouch, a spout is attached to one pleated portion of the lower gusset portion, and one pleated portion is attached to the upper gusset portion. In order to provide a liquid inlet for the other pleated part, the upper edge is heat-sealed with the upper sealing part, and an opening means is provided below it, and further resealed below it. Since a zipper-type fastener is provided as a means, it is excellent in functionality, but the manufacturing process becomes complicated and inferior in productivity.In particular, a zipper-type fastener as a means for resealing a liquid inlet has a factor in increasing costs. As a result, there was a problem that productivity and economy were inferior as a whole.

本発明は、前記のような問題点を解決するためになされたものであり、その課題は、主に医療機関で入院患者等に流動食を投与するために使用される注出口付きパウチであって、流動食を投与する際、そのまま注出口に供給チューブを連結して衛生的且つ簡便に患者等に投与することができると共に、流動食の希釈など調整が必要な場合、或いは、流動食の投与後、そのパウチを利用して飲料水などを投与する場合にも、パウチに形成した液体注入口から希釈液や飲料水などを容易に注入することができ、注入後、開口した液体注入口の再封も容易で、特にコストアップもなく、衛生的且つ簡便に飲料水なども投与することができるという、医療現場での使い勝手がよく、且つ衛生性、生産性、経済性にも優れた流動食用の注出口付きパウチを提供することである。   The present invention has been made in order to solve the above-mentioned problems, and the subject thereof is a pouch with a spout mainly used for administering liquid food to hospitalized patients in medical institutions. When the liquid food is administered, the supply tube can be directly connected to the spout and can be administered to the patient in a sanitary and simple manner. If adjustment such as dilution of the liquid food is necessary, or After administration, even when drinking water is administered using the pouch, a diluent or drinking water can be easily injected from the liquid inlet formed in the pouch. It is easy to re-seal, has no particular cost increase, and can be administered in a sanitary and simple manner such as drinking water. It is easy to use in the medical field and has excellent hygiene, productivity and economy. Pouch with spout for liquid food It is to provide.

本発明の注出口付きパウチは、流動食等を密封した後、通常は加圧加熱殺菌処理が行われるため、パウチの積層フィルムおよびパウチの下部の端縁部に取り付ける注出口は、これに耐える耐熱性が必要である。従って、パウチの積層フィルムのシーラント層には、無延伸のポリプロピレン（ＣＰＰ）、高密度ポリエチレン（ＨＤＰＥ）、中密度ポリエチレン（ＭＤＰＥ）のほか、加圧加熱殺菌処理の条件によっては直鎖状低密度ポリエチレン（ＬＬＤＰＥ）などを使用することができる。
また、注出口は、通常、プラスチックの射出成形により作製されるが、パウチへの取り付けは、熱接着方式で行うことが安全性、生産性の点で好ましく、そのためには注出口の樹脂は、パウチの積層フィルムのシーラント層と熱接着可能な樹脂であることが必要であり、例えば、シーラント層にポリプロピレンを用いた場合は、注出口にもポリプロピレンを用い、シーラント層に高密度ポリエチレンを用いた場合は、注出口にも高密度ポリエチレンを用いるというようにシーラント層と注出口の樹脂には、同一または同系統の樹脂を組み合わせて用いることが好ましい。 Since the pouch with a spout of the present invention is usually subjected to heat and pressure sterilization after sealing the liquid food or the like, the spout attached to the laminated film of the pouch and the lower edge of the pouch withstands this. Heat resistance is necessary. Therefore, the sealant layer of the laminated film of pouches includes unstretched polypropylene (CPP), high density polyethylene (HDPE), medium density polyethylene (MDPE), and linear low density depending on the conditions of pressure heat sterilization treatment. Polyethylene (LLDPE) or the like can be used.
In addition, the spout is usually produced by injection molding of plastic, but the attachment to the pouch is preferably performed by a heat bonding method from the viewpoint of safety and productivity. It is necessary to be a resin that can be thermally bonded to the sealant layer of the laminated film of the pouch. For example, when polypropylene is used for the sealant layer, polypropylene is also used for the spout and high-density polyethylene is used for the sealant layer. In this case, it is preferable to use a resin of the same or the same system in combination for the sealant layer and the resin of the spout, such as using high-density polyethylene for the spout.

このような注出口５０が取り付けられた注出口付きパウチに充填された流動食を患者等に投与する際には、注出口本体５１に装着されたキャップ５３を外し、図１０の（ロ）の（ａ）、（ｂ）に示すように、患者等の体内に一端が挿入された供給チューブＴの他端に取り付けられた連結具Ｃを注出口本体５１の先端部に差し込むことにより、その突き刺し突起２６で注出口シール材５２が突き破られ、リング状突起２２で注出口本体５１に固定されると共に、突き刺し突起２６に設けられた切り欠き部２７から流動食が供給チューブＴ内に流出し、患者等に投与できるようになる。 Such a spout 50 can be attached by being thermally bonded by a method in which the adhesive base 23 is inserted between the wall films before and after the attachment position of the pouch and thermocompression bonded.
When a liquid food filled in a pouch with a spout attached with such a spout 50 is to be administered to a patient or the like, the cap 53 attached to the spout main body 51 is removed, and (b) in FIG. As shown in (a) and (b), the connector C attached to the other end of the supply tube T having one end inserted into the body of a patient or the like is inserted into the distal end portion of the spout main body 51 so that the piercing is performed. The spout 26 seals the spout sealing material 52 and is fixed to the spout main body 51 by the ring-shaped protrusion 22, and the liquid food flows into the supply tube T from the notch 27 provided in the piercing protrusion 26. Can be administered to patients.

このように供給チューブＴが連結された前記注出口付きパウチ１００、２００を、吊り下げ用の穴９を利用して、スタンドなどのフックに吊り下げることにより、注出口５０がパウチの最下部に位置するようになるので、患者等に流動食を最後までスムーズに注出投与することができる。   The pouches 100 and 200 with the spout connected to the supply tube T in this way are suspended from a hook such as a stand by using the suspension hole 9 so that the spout 50 is placed at the bottom of the pouch. Since it comes to be located, a liquid food can be smoothly poured and administered to a patient etc. to the last.

図１、図２に示したような構成を採ることにより、注出口付きパウチ１００、２００に充填された流動食を患者等に投与する際には、注出口５０の注出口本体５１に装着されたキャップ５３を外して、図１０で説明したように、注出口本体５１の先端部に、一端が患者等の体内（腸など）に挿入された供給チューブＴの他端に取り付けられた連結具Ｃを差し込むことにより、その突き刺し突起２６で注出口シール材５２が突き破られ、リング状突起２２で注出口本体５１に固定されると共に、突き刺し突起２６に設けられた切り欠き部２７から流動食が供給チューブＴ内に流出し、患者等に投与できる状態となる。
このように供給チューブＴを連結した注出口付きパウチ１００、２００を、パウチ上部の拡大シール部４に設けられた吊り下げ用の穴９を利用して、患者等の傍らに設置されたスタンドのフックなどに掛けて吊り下げることにより、流動食が供給チューブＴ内に流出し、患者等に流動食の投与を開始することができる。この時、注出口５０はパウチの最下部に位置するようになり、且つ、注出口５０の両側の底部シール部７は、注出口５０の両側からパウチの両側部に向かって傾斜をもって高くなるシールパターンでヒートシールされているので、確実に流動食が注出口５０に誘導され、最後までスムーズに流動食を患者等に注出投与することができる。 By adopting the configuration as shown in FIGS. 1 and 2, when the liquid food filled in the pouches 100, 200 with the spout is administered to a patient or the like, it is attached to the spout main body 51 of the spout 50. As shown in FIG. 10, the connector 53 is attached to the distal end of the spout main body 51 and attached to the other end of the supply tube T inserted into the body of the patient or the like (intestine or the like). When C is inserted, the spout projection sealing material 52 is pierced by the piercing projection 26 and is fixed to the spout main body 51 by the ring-shaped projection 22, and the liquid food is fed from the notch portion 27 provided in the piercing projection 26. Flows out into the supply tube T and can be administered to a patient or the like.
In this way, the pouches 100 and 200 with spouts connected to the supply tube T are connected to the patient or the like by using the suspension holes 9 provided in the enlarged seal part 4 at the top of the pouch. By hanging on a hook or the like, the liquid food flows out into the supply tube T, and administration of the liquid food to the patient or the like can be started. At this time, the spout 50 is positioned at the lowermost part of the pouch, and the bottom seal portions 7 on both sides of the spout 50 are sealed so as to increase from the both sides of the spout 50 toward both sides of the pouch. Since the pattern is heat-sealed, the liquid food is reliably guided to the spout 50, and the liquid food can be smoothly dispensed and administered to the patient or the like.

また、最初に流動食の希釈などの調整が必要な場合、或いは、流動食の投与後、その注出口付きパウチ１００、２００を利用して飲料水などを患者等に投与する場合には、パウチ上部のガセット部３の前面側のひだ状部８a に開封手段として設けられた切り取り線１３とその両端に設けられたノッチ１４a 、１４b を利用して、例えば右側のノッチ１４b から切り取り線１３に沿って、その上の拡大シール部４を切り取ることにより、前面側のひだ状部８a を液体注入口として大きく開口させることができ、その開口部から希釈液や飲料水などを容易に注入することができる。   In addition, when adjustment such as dilution of the liquid food is necessary first, or when drinking water or the like is administered to the patient or the like using the pouches 100 and 200 with the spout after administration of the liquid food, the pouch For example, along the cut line 13 from the right notch 14b using the cut lines 13 provided as opening means in the pleated portion 8a on the front side of the upper gusset 3 and notches 14a and 14b provided at both ends thereof. By cutting off the enlarged seal portion 4 thereabove, the front side pleated portion 8a can be opened widely as a liquid injection port, and a diluent, drinking water, etc. can be easily injected from the opening. it can.

希釈液や飲料水などを注入した後、液体注入口を再封する際は、その開口部を閉じ、図１に示した注出口付きパウチ１００の場合は、前面側のひだ状部８a を折り曲げ線１５で前側下方に折り返すことにより、折り曲げ線１５の左右の上下に設けられた係止部１０a 、１０b と係止部１０c 、１０d が、それぞれ上側の係止部１０a 、１０c の上下の向きが逆になって下側の係止部１０b 、１０d と前後に重なり合うので、重なり合った係止部の係止片１２a 、１２b 、および係止片１２c 、１２d の前後の位置関係を入れ換えることにより、図３に示したように、折り返した前面側のひだ状部が閉じた状態に係止され、開封された液体注入口を再封することができる。   When the liquid inlet is resealed after injecting a diluent or drinking water, the opening is closed, and in the case of the pouch 100 with a spout shown in FIG. 1, the pleated portion 8a on the front side is bent. By folding the line 15 downward and forward, the locking portions 10a and 10b and the locking portions 10c and 10d provided on the upper and lower sides of the bending line 15 are respectively in the vertical direction of the upper locking portions 10a and 10c. On the contrary, the lower locking portions 10b and 10d overlap with each other in the front-rear direction. Therefore, by replacing the front-rear positional relationship between the locking pieces 12a and 12b and the locking pieces 12c and 12d of the overlapping locking portions, FIG. As shown in FIG. 3, the folded front pleat is locked in a closed state, and the opened liquid inlet can be resealed.

また、図２に示した注出口付きパウチ２００の場合は、液体注入口の開口部を閉じた後、前面側のひだ状部８a の上部を先ず上側の折り曲げ線１５a で前側下方に折り返し、次いで、折り返された前面側のひだ状部８a を下側の折り曲げ線１５で再度前側下方に巻き込むように折り返すことにより、折り曲げ線１５の左右の上下に設けられた係止部１０a 、１０b と係止部１０c 、１０d が、それぞれ係止部の向きが逆になった状態で前後に重なり合うので、重なり合った係止部の係止片１２a 、１２b 、および係止片１２c 、１２d の前後の位置関係を入れ換えることにより、図４に示したように、折り返した前面側のひだ状部が閉じた状態に係止され、開封された液体注入口を再封することができる。この場合、開封された前面側のひだ状部８a を二段階に折り返して再封しているので、一層確実に開封された液体注入口を再封することができる。   In the case of the pouch 200 with a spout shown in FIG. 2, after closing the opening of the liquid inlet, the upper portion of the pleated portion 8a on the front side is first folded forward and downward at the upper fold line 15a. The folded fold-like portion 8a on the front side is folded back so as to be wound downward again at the lower fold line 15 so that the fold-like fold portion 8a is engaged with the locking portions 10a, 10b provided on the upper and lower sides of the fold line 15. Since the portions 10c and 10d overlap each other in the state in which the directions of the locking portions are reversed, the positional relationship between the locking pieces 12a and 12b and the locking pieces 12c and 12d of the overlapping locking portions is determined. As shown in FIG. 4, the folded fold-like portion on the front side is locked in a closed state, and the opened liquid inlet can be resealed. In this case, the opened front pleated portion 8a is folded back and resealed in two stages, so that the opened liquid inlet can be resealed more reliably.

以上のような液体注入口の開封、および開口させた液体注入口からの希釈液や飲料水などの注入、そして、注入後の液体注入口の再封の一連の操作は、注出口付きパウチ１００、２００をスタンドのフックなどに吊り下げた状態で行えるので、簡便に行うことができる。また、液体注入口の再封も確実に行われるので、落下菌や塵埃などの混入のおそれもなく、衛生的且つスムーズに流動食や飲料水などを患者等に投与することができる。
従って、本発明の注出口付きパウチは、従来の注出口付きパウチと比較して、医療現場での使い勝手が一層よく、且つ、衛生面のほか経済性にも優れている。 The series of operations of opening the liquid inlet as described above, injecting a diluent, drinking water, etc. from the opened liquid inlet, and resealing the liquid inlet after the injection, is performed with a pouch 100 with a spout. , 200 can be performed in a state where it is suspended from a hook or the like of a stand. In addition, since the liquid injection port is securely resealed, liquid food, drinking water, and the like can be administered to a patient and the like in a sanitary and smooth manner without fear of contamination with falling bacteria or dust.
Therefore, the pouch with a spout of the present invention is more convenient for use in the medical field than the conventional pouch with a spout and is superior in terms of hygiene and economy.

次に、図５〜図９は、それぞれ本発明の流動食用の注出口付きパウチの上部の左右両側の広幅シール部に設ける係止部の図１とは異なる第２〜第６の係止部の形状を示す要部の正面図である。
只、各図において、折り曲げ線１５の左右両側の上下に設ける係止部１０a 〜１０d は、上下の係止部が一対になって係合するものであり、上下の係止部が所定の向きに設けられていればよく、左右では図示したように上下の向きが逆であってもよい。
また、係止部の形状の説明は、左側の係止部と右側の係止部とでその向きが異なるが１８０°回転させると同一パターンであるため、折り曲げ線１５の右上側の係止部１０c を代表として説明する。
即ち、図１に示した係止部１０c が、パウチの外側端部から内側に向かう横方向の切り目線とそれに続いてＲをとって垂直上方に向かう切り目線とその上端で外側に曲がる戻り部が設けられた鉤状（Ｌ字状）の切り目線１１c で設けられた構成であるのに対して、図５に示した係止部１０c は、パウチの外側端部から内側に向かう横方向の短い切り目線とそれに続いて斜め内側上方に向かう切り目線とその上端で外側に曲がる戻り部が設けられた形状の切り目線１１c を設けて、係止片１２c が形成されるように構成したものである。 Next, FIG. 5 to FIG. 9 are second to sixth locking portions different from FIG. 1 of the locking portions provided on the wide seal portions on the left and right sides of the upper part of the pouch with a spout for liquid food according to the present invention. It is a front view of the principal part which shows the shape of this.
In each figure, the locking portions 10a to 10d provided on the upper and lower sides of the folding line 15 are engaged with a pair of upper and lower locking portions, and the upper and lower locking portions are in a predetermined direction. As shown in the figure, the vertical direction may be reversed on the left and right.
The description of the shape of the locking part is the same pattern when the left locking part and the right locking part have different directions but are rotated 180 °, so the locking part on the upper right side of the folding line 15 10c will be described as a representative.
That is, the locking portion 10c shown in FIG. 1 has a horizontal cut line extending inward from the outer end portion of the pouch, followed by a cut line extending vertically upward with R, and a return portion bent outward at the upper end thereof. 5 is provided with a hook-like (L-shaped) cut line 11c provided with a locking portion 10c shown in FIG. 5 in the lateral direction from the outer end of the pouch to the inside. A locking line 12c is formed by providing a short score line, followed by a score line 11c having a shape that is provided with a return line that bends outward at an upper end and a score line that extends obliquely inward and upward. is there.

図６に示した係止部１０c は、図示したように、パウチの外側端部から内側に向かう横方向の切り目線とそれに続いてＲをとって斜め外側上方に伸びる切り目線とその上端で外側下方に曲がる戻り部が設けられた形状の切り目線１１c を設けて、係止片１２c が形成されるように構成したものである。   As shown in FIG. 6, the locking portion 10c shown in FIG. 6 has a lateral cut line extending inward from the outer end of the pouch, followed by a cut line extending diagonally upward and taking an R, and an outer end at the upper end thereof. A cut line 11c having a shape provided with a return portion that bends downward is provided to form a locking piece 12c.

図７に示した係止部１０c は、図示したように、パウチの外側端部から内側にＶ字状に傾斜して下がった後、Ｒをもって斜め上方に折り返し、それに続いて垂直上方に伸びる切り目線とその上端で外側に曲がる戻り部が設けられた形状の切り目線１１c を設けて、係止片１２c が形成されるように構成したものである。   As shown in FIG. 7, the locking portion 10c shown in FIG. 7 is a cut which extends downward in an upward direction with an R after being inclined inwardly in a V shape from the outer end portion of the pouch. The locking line 12c is formed by providing a cut line 11c having a shape having a line of sight and a return portion bent outward at the upper end thereof.

図８に示した係止部１０c は、図示したように、パウチの外側端部から内側にＵ字状に一旦下がった後、曲線状に上方に折り返し、それに続いて垂直上方に伸びる切り目線とその上端で外側に曲がる戻り部が設けられた形状の切り目線１１c を設けて、係止片１２c が形成されるように構成したものである。   As shown in FIG. 8, the locking portion 10c shown in FIG. 8 has a cut line extending from the outer end of the pouch to the inside in a U-shape, then folded upward in a curved shape, and then extending vertically upward. The engaging line 12c is formed by providing a cut line 11c having a shape in which a return portion that is bent outward at the upper end is provided.

図９に示した係止部１０c は、図示したように、パウチの外側端部から内側に向かう横方向の短い切り目線とそれに続いて斜め内側下方に向かう切り目線とその下端からＲをもって垂直上方に伸びる切り目線とその上端で外側に曲がる戻り部が設けられた形状の切り目線１１c を設けて、係止片１２c が形成されるように構成したものである。   As shown in FIG. 9, the locking portion 10c shown in FIG. 9 has a short horizontal cut line extending inward from the outer end of the pouch, followed by a cut line extending obliquely inward and downward, and R extending vertically from the lower end thereof. A locking line 12c is formed by forming a cutting line 11c having a shape in which a cutting line extending in a straight line and a return portion bent outward at the upper end thereof are provided.

以上、図５〜図９に示した係止部１０a 〜１０d は、個々には例えば、図５に示した形状の係止部１０c では、下側から斜め内側上方に向かう切り目線部が設けられているので、図３に示したように、前後に重なり合う係止片１２a と１２b 、および係止片１２c と１２d の前後の位置関係を入れ換えて係止する際、容易に入れ換えて係止できる特徴があり、また、図６に示した形状の係止部１０c では、パウチの外側端部から内側に向かう横方向の切り目線とそれに続いてＲをもって斜め外側上方に伸びる切り目線が設けられているので、図３に示したように、前後に重なり合う係止片１２a と１２b 、および係止片１２c と１２d の前後の位置関係を入れ換えて係止した際、係止部が外れにくくなる特徴があるなど、その係止性に関して多少の差はあるが、全体的には、図１に示した形状の係止部１０a 〜１０d と同様に、図３に示したように、前後に重なり合う係止片１２a と１２b 、および係止片１２c と１２d の前後の位置関係を入れ換えて、安定した状態に係止することができるので、開封した液体注入口を確実に再封することができる。
また、図５〜図９に示した形状の係止部１０a 〜１０d は、図２に示した注出口付きパウチ２００のように、横方向の折り曲げ線を、折り曲げ線１５a と折り曲げ線１５のように、２本設けた構成に対しても、上下で一対となる係止部１０a 、１０b 、および係止部１０c 、１０d の上下の向きを適宜変更して設けることにより同様に適用できるものである。 As described above, the locking portions 10a to 10d shown in FIGS. 5 to 9 are individually provided with, for example, a cut line portion diagonally upward from the lower side in the locking portion 10c having the shape shown in FIG. Therefore, as shown in FIG. 3, when the front and rear locking pieces 12a and 12b and the front and rear positions of the locking pieces 12c and 12d are switched to be locked, they can be easily switched and locked. In addition, the locking portion 10c having the shape shown in FIG. 6 is provided with a horizontal score line extending inward from the outer end portion of the pouch, and subsequently a score line extending obliquely outwardly upward with R. Therefore, as shown in FIG. 3, when the front and rear locking pieces 12a and 12b and the front and rear positions of the locking pieces 12c and 12d are switched and locked, the locking portion is difficult to come off. Etc. However, as a whole, like the locking portions 10a to 10d having the shape shown in FIG. 1, as shown in FIG. 3, the locking pieces 12a and 12b and the locking pieces 12c and 12d overlapping each other as shown in FIG. Since the positional relationship before and after can be switched and locked in a stable state, the opened liquid inlet can be reliably resealed.
Further, the locking portions 10a to 10d having the shapes shown in FIG. 5 to FIG. 9 have the folding lines in the horizontal direction like the folding lines 15a and 15 like the pouch 200 with the spout shown in FIG. In addition, the present invention can be similarly applied to a configuration in which two are provided by appropriately changing the upper and lower directions of the locking portions 10a and 10b and the locking portions 10c and 10d that are paired up and down. .

また、以上のようなパウチの再封手段は、図１、図２に示したような流動食用の注出口付きパウチに限らず、注出口を設けていない一般のパウチにも簡便でコストのかからない再封手段として好適に適用できるものであり、その場合、図１、図２に示した注出口付きパウチ１００、２００の構成において、注出口５０を取り除き、底部シール部７を所定幅のフラットなシールパターンでヒートシールし、上部のガセット部３も吊り下げ用の穴９を必要としない場合は、拡大シール部４を通常の所定幅の上部シール部に変更してパウチを作製する方法で、再封性を備えたパウチを作製することができる。   The pouch resealing means as described above is not limited to a pouch with a pouring outlet for liquid food as shown in FIGS. 1 and 2, but is also simple and cost-effective for general pouches not provided with a pouring outlet. In this case, in the configuration of the pouches 100 and 200 with the spout shown in FIGS. 1 and 2, the spout 50 is removed and the bottom seal portion 7 is flattened with a predetermined width. When heat sealing with a seal pattern and the upper gusset portion 3 does not require the hole 9 for hanging, the enlarged seal portion 4 is changed to an upper seal portion having a normal predetermined width, and a pouch is produced. A pouch having resealability can be produced.

次に、本発明の注出口付きパウチに用いる積層フィルムについて説明する。
本発明の流動食用の注出口付きパウチは、流動食の密封後、通常は加圧加熱殺菌処理が施されるため、注出口と共に、パウチの積層フィルムは、これに耐える耐熱性が必要である。また、流動食の患者等への投与中、流動食の残量などを表示する目盛りなどがパウチに設けられるため、パウチの積層フィルムは透明性を有することも必要である。更に、密封された流動食の保存性を高めるためには、パウチの積層フィルムはガスバリヤー性に優れることが好ましい。 Next, the laminated film used for the pouch with a spout of the present invention will be described.
Since the pouch with a spout for liquid food of the present invention is usually subjected to pressure heat sterilization after sealing the liquid food, the laminated film of the pouch together with the spout needs heat resistance to withstand this. . Moreover, since the scale etc. which display the residual amount of a liquid food etc. are provided in a pouch during administration to a patient etc. of a liquid food, it is also necessary for the laminated film of a pouch to have transparency. Furthermore, in order to improve the storage stability of the sealed liquid food, it is preferable that the laminated film of the pouch is excellent in gas barrier properties.

このような性能を備えた積層フィルムとしては、特に限定はされないが、代表的な構成例として以下のような構成の積層フィルムが挙げられる。
(1) ＰＥＴフィルム／接着剤／無機酸化物の蒸着層・ＯＮフィルム／接着剤／ＣＰＰフィルム（シーラント層）
(2) ＰＥＴフィルム・無機酸化物の蒸着層／接着剤／ＯＮフィルム／接着剤／ＣＰＰフィルム（シーラント層）
(3) ＰＥＴフィルム／接着剤／無機酸化物の蒸着層・ＯＮフィルム／接着剤／一軸延伸又は二軸延伸フィルム／接着剤／ＣＰＰフィルム（シーラント層）
(4) ＰＥＴフィルム・無機酸化物の蒸着層／接着剤／ＯＮフィルム／接着剤／一軸延伸又は二軸延伸フィルム／接着剤／ＣＰＰフィルム（シーラント層）
(5) ＰＥＴフィルム／接着剤／ＥＶＯＨフィルム／接着剤／ＯＮフィルム／接着剤／ＣＰＰフィルム（シーラント層）
(6) ＰＥＴフィルム／接着剤／ＥＶＯＨフィルム／接着剤／ＯＮフィルム／接着剤／一軸延伸又は二軸延伸フィルム／接着剤／ＣＰＰフィルム（シーラント層）
(7) ＰＥＴフィルム・有機ガスバリヤー性コート層／接着剤／ＯＮフィルム／接着剤／ＣＰＰフィルム（シーラント層）
(8) ＰＥＴフィルム／接着剤／有機ガスバリヤー性コート層・ＯＮフィルム／接着剤／ＣＰＰフィルム（シーラント層）
などが挙げられるが、これらに限定されるものではなく様々な組み合わせの積層フィルムを使用することができる。 Although it does not specifically limit as a laminated film provided with such performance, The laminated film of the following structures is mentioned as a typical structural example.
(1) PET film / adhesive / deposited layer of inorganic oxide / ON film / adhesive / CPP film (sealant layer)
(2) PET film / deposited layer of inorganic oxide / adhesive / ON film / adhesive / CPP film (sealant layer)
(3) PET film / adhesive / deposited layer of inorganic oxide / ON film / adhesive / uniaxially stretched or biaxially stretched film / adhesive / CPP film (sealant layer)
(4) PET film / deposited layer of inorganic oxide / adhesive / ON film / adhesive / uniaxially stretched or biaxially stretched film / adhesive / CPP film (sealant layer)
(5) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / CPP film (sealant layer)
(6) PET film / adhesive / EVOH film / adhesive / ON film / adhesive / uniaxially stretched or biaxially stretched film / adhesive / CPP film (sealant layer)
(7) PET film / organic gas barrier coating layer / adhesive / ON film / adhesive / CPP film (sealant layer)
(8) PET film / adhesive / organic gas barrier coat layer / ON film / adhesive / CPP film (sealant layer)
However, the present invention is not limited to these, and various combinations of laminated films can be used.

上記構成において、ＰＥＴフィルムは２軸延伸ポリエチレンテレフタレートフィルム、ＯＮフィルムは２軸延伸ナイロンフィルム、ＣＰＰフィルムは無延伸ポリプロピレンフィルム、ＥＶＯＨフィルムはエチレン−酢酸ビニル共重合体ケン化物フィルムを指すものである。
また、無機酸化物の蒸着層は、具体的には、シリカ、アルミナ、酸化亜鉛、酸化マグネシウムなどの無機酸化物の蒸着層を、ＰＥＴフィルムやＯＮフィルムなどの耐熱性基材フィルムの上に２００〜１０００Åの厚みに蒸着して使用することができる。
有機ガスバリヤー性コート層は、具体的には、ポリ塩化ビニリデンのコート層（厚み２〜８μｍ程度）のほか、ポリアクリル酸架橋樹脂などのコート層（厚み１〜５μｍ程度）を好適に使用することができる。特にポリアクリル酸架橋樹脂のコート層は、ガスバリヤー性と共に耐熱性にも優れており、ＰＥＴフィルムなどの耐熱性基材フィルムにコートして用いることにより、加圧加熱殺菌処理が施される本発明の注出口付きパウチには好適に使用できる。 In the above configuration, the PET film is a biaxially stretched polyethylene terephthalate film, the ON film is a biaxially stretched nylon film, the CPP film is an unstretched polypropylene film, and the EVOH film is a saponified ethylene-vinyl acetate copolymer film.
In addition, the inorganic oxide vapor-deposited layer is specifically formed by depositing an inorganic oxide vapor-deposited layer such as silica, alumina, zinc oxide or magnesium oxide on a heat-resistant substrate film such as a PET film or an ON film. It can be vapor-deposited to a thickness of ˜1000 mm.
Specifically, the organic gas barrier coat layer preferably uses a coat layer (thickness of about 1 to 5 μm) such as a polyacrylic acid crosslinked resin in addition to a polyvinylidene chloride coat layer (thickness of about 2 to 8 μm). be able to. In particular, the polyacrylic acid crosslinked resin coating layer is excellent in both gas barrier properties and heat resistance, and is coated with a heat resistant substrate film such as a PET film to be subjected to pressure and heat sterilization treatment. It can be suitably used for the pouch with a spout of the invention.

前記ＰＥＴフィルムやＯＮフィルムは、基材フィルムとして作用し、パウチに機械的強度のほか耐熱性を付与し、最外層に用いたＰＥＴフィルムは印刷適性も付与するものである。ＯＮフィルムは、多少吸湿性を有するため本発明の注出口付きパウチでは中間層に用いることが好ましいが、突き刺し強度や屈曲強度に優れるため、液体用パウチの強度を向上できる点で特に有用である。   The PET film or ON film acts as a base film, imparts heat resistance to the pouch in addition to mechanical strength, and the PET film used for the outermost layer also imparts printability. Since the ON film has some hygroscopicity, it is preferably used for the intermediate layer in the pouch with a spout of the present invention. However, the ON film is particularly useful in that it can improve the strength of the liquid pouch because it has excellent puncture strength and bending strength. .

中間層の無機酸化物の蒸着層、ＥＶＯＨフィルム、有機ガスバリヤー性コート層は、いずれも透明性を有するガスバリヤー層として積層したものである。
中間層に一軸延伸フィルムを積層する場合は、一軸延伸ポリプロピレンフィルム、一軸延伸高密度ポリエチレンフィルム、一軸延伸ポリエチレンテレフタレートフィルムなどを使用することができ、その延伸方向がパウチの液体注入口を開封するための切り取り線の方向と一致するように積層することにより、開封手段の一つとして、液体注入口を開封する際、切り取り線に沿って容易に引き裂いて開封できるようになる。
また、中間層に二軸延伸フィルムを積層する場合は、二軸延伸ポリプロピレンフィルム、二軸延伸高密度ポリエチレンフィルムなどを使用することができ、それにより積層フィルムの厚みを増し、剛性、機械的強度を高めるほか、水蒸気バリヤー性も向上させることができる。 The intermediate oxide vapor deposition layer, EVOH film, and organic gas barrier coating layer are all laminated as a gas barrier layer having transparency.
When a uniaxially stretched film is laminated on the intermediate layer, a uniaxially stretched polypropylene film, a uniaxially stretched high-density polyethylene film, a uniaxially stretched polyethylene terephthalate film, or the like can be used, and the stretch direction opens the liquid inlet of the pouch. When the liquid injection port is opened as one of the opening means, it can be easily torn and opened along the cut line.
When a biaxially stretched film is laminated on the intermediate layer, a biaxially stretched polypropylene film, a biaxially stretched high-density polyethylene film, or the like can be used, thereby increasing the thickness of the laminated film and increasing the rigidity and mechanical strength. In addition, the water vapor barrier property can be improved.

最内層のＣＰＰフィルムは、ヒートシール用のシーラント層として作用すると共に、耐熱性、低臭性に優れるので、本発明のような内容物の密封後に、パウチごと加圧加熱殺菌処理される流動食用のパウチには特に好ましく用いられる。
