Description

本発明は、包装袋セットに関し、特に、軟包材からなり、内部に液状またはゲル状の収納物を包装する包装袋と、収納物を外部に排出する接続具とを具備する包装袋セットに関するものである。 The present invention relates to a packaging bag set, and more particularly to a packaging bag set which is made of a flexible packaging material and includes a packaging bag for wrapping a liquid or gel-like stored matter inside and a connector for discharging the stored matter to the outside. It is a thing.

病院などで患者などに経口あるいは経腸により栄養剤や医薬品、流動食などを投与するとき、これらを胃や腸に挿入したチューブを通して投与することがある。また、輸液などを点滴するときにも、チューブを通して中空針から輸液などを患者の体内に送り込むことがある。 When administering nutritional supplements, medicines, liquid foods, etc. to patients orally or by intestines at hospitals, they may be administered through a tube inserted into the stomach or intestines. In addition, when an infusion solution or the like is infused, the infusion solution or the like may be sent into the patient's body from a hollow needle through a tube.

このような患者に投与する栄養剤や医薬品などは容器に充填されていて、容器を吊り下げて、容器の下端よりチューブを通して栄養剤や医薬品などを流出させて投与されている。このような容器とチューブとを接続するために、容器にはスパウト部材等の部材が設けられていた。 The nutritional supplements and medicines to be administered to such patients are filled in a container, and the container is hung and the nutritional supplements and medicines are discharged from the lower end of the container through a tube. In order to connect such a container and a tube, the container is provided with a member such as a spout member.

また、容器においても従来はガラス瓶やプラスチックボトルが用いられていたが、最近では軟包装袋が用いられる様になってきた。しかし、軟包装袋においても、スパウト部材等の部材が設けられていた。 In addition, glass bottles and plastic bottles have been used for containers in the past, but recently, flexible packaging bags have come to be used. However, even in the flexible packaging bag, members such as spout members are provided.

例えば、特許文献１の「経管投与剤用接続具」においては、フィルムにより製袋された経管投与剤容器に液密にスパウト部材が接合されていて、このスパウト部材に係脱可能に経管投与剤用接続具が接続され、経管投与剤をチューブに導入する様になっている。 For example, in the "connector for a tube-administered agent" of Patent Document 1, a spout member is liquid-tightly bonded to a tube-administered agent container made of a film, and the spout member can be engaged with and detached from the spout member. A tube-administered connector is connected to introduce the tube-administered agent into the tube.

このように投与剤を収納する軟包装袋にスパウト部材等の部材を設けるには、軟包装袋の製造に当たって加工工程が増え、また、スパウト部材等の部材を用意しなければならないなどコストアップや製造時間が長くなるなどの問題がある。さらに、製造後の保管や輸送のためのスペースが必要となるなどコストアップの要因になる。 In order to provide a member such as a spout member in the flexible packaging bag for storing the administration agent in this way, the number of processing steps increases in the manufacture of the flexible packaging bag, and the cost increases such as the need to prepare the member such as the spout member. There are problems such as long manufacturing time. In addition, it requires space for storage and transportation after manufacturing, which is a factor of cost increase.

（包装体の構成）
まず、包装袋１００について説明する。図２は、実施形態に係る包装袋の平面図である。図２に示すように、実施形態に係る包装袋１００は、収納物を収納する収納部１１９と、収納部１１９に接続され、収納部１１９の内部に収納された収納物を収納部１１９の外部へと導く注出部１２０と、包装袋１００の開封時に注出部１２０の一部を横断する切断位置で切断除去される切断除去部１２３とを備える。 (Composition of packaging)
First, the packaging bag 100 will be described. FIG. 2 is a plan view of the packaging bag according to the embodiment. As shown in FIG. 2, the packaging bag 100 according to the embodiment is connected to a storage unit 119 for storing stored items and a storage unit 119, and stores the stored items stored inside the storage unit 119 outside the storage unit 119. It is provided with a dispensing section 120 leading to the package bag 100, and a cutting / removing section 123 that is cut and removed at a cutting position that crosses a part of the dispensing section 120 when the packaging bag 100 is opened.

包装袋１００は、互いに重ね合わせた２枚のシートの周囲をヒートシールしたパウチにより構成される。より具体的には、図２に示すように、２枚のシートにおける、シール部１１１、１１２、１１３、１１４、１１５、１１６、１１７及び１１８がそれぞれヒートシールされている。尚、本実施形態では２枚のシートを用いてシートの周囲全体をヒートシールしているが、１枚のシートを折り曲げ、折り曲げた一辺以外の周縁部分をヒートシールしてもよい。 The packaging bag 100 is composed of a pouch that heat-seals the periphery of two sheets that are overlapped with each other. More specifically, as shown in FIG. 2, the sealing portions 111, 112, 113, 114, 115, 116, 117 and 118 of the two sheets are heat-sealed, respectively. In the present embodiment, two sheets are used to heat-seal the entire periphery of the sheets, but one sheet may be bent and the peripheral edge portion other than the bent side may be heat-sealed.

収納部１１９は、上端に向かって幅が狭まる形状である。注出部１２０は、収納部１１９の上端の最も幅が狭まった部分に接続され、幅が一定の未シール部よりなる。 The storage portion 119 has a shape in which the width narrows toward the upper end. The dispensing portion 120 is connected to the narrowest portion of the upper end of the storage portion 119, and is composed of an unsealed portion having a constant width.

注出部１２０の収納部１１９と反対側の先端部付近のシール部１１６、１１７には、切断除去部１２３を切断除去する際の切っ掛けとなる一対のノッチ部が形成されている。また、一対のノッチ部を結ぶ線に沿って注出部１２０を横断するように易切断線１２１が設けられている。これにより、切断除去部１２３をノッチ部を切っ掛けに易切断線１２１に沿って切断除去することができる。易切断線１２１は、シートの外側からハーフカット加工などの傷加工を施して設けることができるが、これに限定されない。また、シートの延伸方向と一対のノッチ部を結ぶ方向とを一致させてもよい。この場合、易切断線１２１は設けなくてもよい。また、切断除去部１２３を易切断線１２１に沿って切断除去し易いように、シール部１１８は摘み部として手指で摘まめる十分な大きさに形成されることが好ましい。切断除去部１２３を切断除去することで、注出部１２０に開口が形成される。 A pair of notch portions that serve as a trigger for cutting and removing the cutting and removing portion 123 are formed in the sealing portions 116 and 117 near the tip portion on the opposite side of the dispensing portion 120 from the storage portion 119. Further, an easy cutting line 121 is provided so as to cross the pouring portion 120 along a line connecting the pair of notch portions. As a result, the cutting / removing portion 123 can be cut and removed along the easy cutting line 121 with the notch portion as a trigger. The easy-cutting line 121 can be provided by performing scratch processing such as half-cut processing from the outside of the sheet, but the present invention is not limited to this. Further, the stretching direction of the sheet and the direction connecting the pair of notches may be matched. In this case, the easy cutting line 121 may not be provided. Further, it is preferable that the seal portion 118 is formed to have a size sufficient to be picked by fingers as a grip portion so that the cut removal portion 123 can be easily cut and removed along the easy cutting line 121. By cutting and removing the cutting and removing portion 123, an opening is formed in the dispensing portion 120.

また、シール部１１１には、吊下げ用孔１２２が設けられていて、フックなどの吊下げ具に掛けて包装袋１００を吊下げられるようになっている。 Further, the seal portion 111 is provided with a hanging hole 122 so that the packaging bag 100 can be hung by hanging it on a hanging tool such as a hook.

包装袋１００に用いられるシートには、軟包材であって、ヒートシールが可能な樹脂製の単層フィルムまたは積層フィルムを利用することができるが、基材フィルムとシーラント層とからなる積層フィルムであることが好ましい。単層フィルムとしては、低密度ポリエチレンの無延伸フィルムが好適に用いられる。 As the sheet used for the packaging bag 100, a single-layer film or a laminated film made of a resin which is a soft packaging material and can be heat-sealed can be used, but a laminated film composed of a base film and a sealant layer. Is preferable. As the single-layer film, a low-density polyethylene non-stretched film is preferably used.

積層フィルムの基材フィルムとしては、２軸延伸樹脂フィルムが好ましく用いられ、樹脂としては、ポリプロピレン、ナイロン、ポリエステルなどが好ましく用いられる。また、バリア性を考慮して、積層フィルムに無機酸化物蒸着層を設けても良い。これらは組み合わせて多層の基材フィルムとしても良い。 A biaxially stretched resin film is preferably used as the base film of the laminated film, and polypropylene, nylon, polyester and the like are preferably used as the resin. Further, in consideration of barrier properties, an inorganic oxide-deposited layer may be provided on the laminated film. These may be combined to form a multilayer base film.

シーラント層には酸化防止剤の添加されていない低密度ポリエチレンが好ましく用いられる。 Low-density polyethylene to which no antioxidant is added is preferably used for the sealant layer.

包装袋１００の製袋は、通常のパウチなどを製袋する製袋機で行うことができる。通常のパウチの製袋と同様にヒートシール及び裁断を行うが、このとき、包装袋１００に収納する収納物の充填口として、シール部１１１を未シール部として残しておく。尚、未シール部は、シール部１１１以外のシール部１１２、１１３などの内の一箇所であってもよい。また、吊下げ用孔１２２の形成は、シートの裁断と同時または別工程により行う。 The packaging bag 100 can be made by a bag making machine that makes a normal pouch or the like. Heat sealing and cutting are performed in the same manner as in normal pouch making, but at this time, the sealing portion 111 is left as an unsealed portion as a filling port for the stored items to be stored in the packaging bag 100. The unsealed portion may be one of the sealed portions 112, 113, etc. other than the sealed portion 111. Further, the hanging hole 122 is formed at the same time as the cutting of the sheet or by a separate process.

次に、製袋された包装袋１００に、未シール部にして残した充填口より収納物を充填し、未シール部をシールする。収納物の充填は無菌充填包装で行うのが好ましい。また、収納物の充填後、レトルト殺菌やオートクレーブ滅菌などにより、殺菌、滅菌してもよい。これにより、収納物が収納された包装袋１００を得ることができる。 Next, the packaged bag 100 is filled with the stored material from the filling port left as the unsealed portion, and the unsealed portion is sealed. It is preferable to fill the stored items with aseptic filling and packaging. Further, after filling the stored items, sterilization and sterilization may be performed by retort sterilization, autoclave sterilization, or the like. As a result, it is possible to obtain a packaging bag 100 in which the stored items are stored.

（包装袋セットの使用方法）
次に、本発明に係る包装袋セットの使用方法について、図８及び図９を用いて、図１、図２、図５、図６を併せて参照しながら説明する。図８は、実施形態に係る包装袋に接続具を取り付ける過程を示す図であり、図９は、図１に示す破線で囲まれたＡ部分の拡大図である。 (How to use the packaging bag set)
Next, a method of using the packaging bag set according to the present invention will be described with reference to FIGS. 1, 9, 5, and 6 with reference to FIGS. 8 and 9. FIG. 8 is a diagram showing a process of attaching the connector to the packaging bag according to the embodiment, and FIG. 9 is an enlarged view of a portion A surrounded by a broken line shown in FIG.

まず、図２に示す切断除去部１２３が切断除去されていない未開封状態の包装袋１００に対して、切断除去部１２３をノッチ部を切っ掛けに易切断線１２１に沿って切断除去することで包装袋１００の注出部１２０に開口を形成する。次に、図５、図６のように外巻部材２０１の一対の分割体２０２を開いた状態で、差込部材２０３の他方部２１１を、包装袋１００の注出部１２０に形成された開口部に図８のように差し込む。尚、本実施形態と異なり差込部材２０３と外巻部材２０１とが接合されていない場合には、差込部材２０３及び外巻部材２０１を図５及び図６に示すように配置した後に差込部材２０３の他方部２１１を注出部１２０に形成された開口部に差し込んでもよいし、差込部材２０３の他方部２１１を注出部１２０に形成された開口部に差し込んだ後に外巻部材２０１を図８に示すように配置してもよい。 First, the unopened packaging bag 100 in which the cutting / removing portion 123 shown in FIG. 2 has not been cut / removed is packaged by cutting / removing the cutting / removing portion 123 along the easy cutting line 121 with the notch portion as a sack. An opening is formed in the pouring portion 120 of the bag 100. Next, with the pair of divided bodies 202 of the outer winding member 201 opened as shown in FIGS. 5 and 6, the other portion 211 of the insertion member 203 is opened in the pouring portion 120 of the packaging bag 100. Insert it into the part as shown in FIG. When the insertion member 203 and the outer winding member 201 are not joined unlike the present embodiment, the insertion member 203 and the outer winding member 201 are arranged as shown in FIGS. 5 and 6 and then inserted. The other portion 211 of the member 203 may be inserted into the opening formed in the pouring portion 120, or the outer winding member 201 may be inserted after inserting the other portion 211 of the insertion member 203 into the opening formed in the pouring portion 120. May be arranged as shown in FIG.

次に、係合片２０６ａと係合片２０６ｂとを係合させてロックして、接続具２００に包装袋１００を固定する。このとき、上述した様に、係合片２０６ａ、２０６ｂの下方、および、ヒンジ２０５の下方にはスリット２０８が形成されるため、外巻部材２０１の一対の分割体２０２を閉じても、包装袋１００のシール部１１４、１１５、１１６、１１７が、このスリットに入り込み、外巻部材２０１の外部に出るため邪魔にならない。次に、図１に示すように、軟包装袋１００の吊下げ用孔１２２を上にして（図示しない）吊下げ具に引っ掛ける。 Next, the engaging piece 206a and the engaging piece 206b are engaged and locked to fix the packaging bag 100 to the connector 200. At this time, as described above, since the slits 208 are formed below the engaging pieces 206a and 206b and below the hinge 205, even if the pair of divided bodies 202 of the outer winding member 201 are closed, the packaging bag The sealing portions 114, 115, 116, 117 of 100 enter the slit and go out of the outer winding member 201, so that they do not get in the way. Next, as shown in FIG. 1, the flexible packaging bag 100 is hooked on a hanging tool with the hanging hole 122 facing up (not shown).

このようにしても、図９に示すように、外巻部材２０１の内周面の一部が略円錐形状の差込部材２０３の外周面に対応する形状に形成され、かつ、外巻部材２０１の内周面と差込部材２０３の外周面とのクリアランスが包装袋１００のシート１枚の厚さ以下であることにより、差込部材２０３の外周面と包装袋１００の注出部１２０の内面との間の摩擦力により差込部材２０３は包装袋１００から抜け難くなり、かつ、外巻部材２０１の内周面に設けられた滑り止め素材により包装袋１００の注出部部分は外巻部材２０１の内周面との間でズレ難くなる。そのため、差込部材２０３の外周面と外巻部材２０１の内周面との間に包装袋１００の注出部１２０が挟まれ固定され、その結果、差込部材２０３が包装袋１００の注出部１２０から抜けたり外れたりすることがほとんどない。 Even in this way, as shown in FIG. 9, a part of the inner peripheral surface of the outer winding member 201 is formed in a shape corresponding to the outer peripheral surface of the insertion member 203 having a substantially conical shape, and the outer winding member 201 is formed. Since the clearance between the inner peripheral surface of the insertion member 203 and the outer peripheral surface of the insertion member 203 is equal to or less than the thickness of one sheet of the packaging bag 100, the outer peripheral surface of the insertion member 203 and the inner surface of the dispensing portion 120 of the packaging bag 100 The insertion member 203 is difficult to be pulled out from the packaging bag 100 due to the frictional force between the insertion member 203, and the ejection portion of the packaging bag 100 is an outer winding member due to the non-slip material provided on the inner peripheral surface of the outer winding member 201. It becomes difficult to shift from the inner peripheral surface of 201. Therefore, the ejection portion 120 of the packaging bag 100 is sandwiched and fixed between the outer peripheral surface of the insertion member 203 and the inner peripheral surface of the outer winding member 201, and as a result, the insertion member 203 dispenses the packaging bag 100. It hardly comes off or comes off from the part 120.

吊下げ用孔１２２を上にして吊下げ具に引っ掛けることで、包装袋１００に収納されていた収納物が、自重によって、注出部１２０から接続具２００の連通孔２０７を通ってチューブ２０４の中空部に流れ込む。そして、チューブ２０４を通して内容物が排出される。 By hooking the hanging tool with the hanging hole 122 facing up, the stored items stored in the packaging bag 100 can be passed through the communication hole 207 of the connecting tool 200 from the dispensing portion 120 to the tube 204 by its own weight. It flows into the hollow part. Then, the contents are discharged through the tube 204.

以上のように、本発明の包装袋セットの構成によれば、収納物を収納した包装袋にスパウト部材等の特段の部材を設けることなく容易に接続可能で、包装袋の収納物をチューブに流出させすることが可能である。また、包装袋の注出部を接続具に固定する際に、包装袋の注出部への差込部材の差し込み及び外巻部材のロックを一連の動作で容易に行うことができるため、片手で接続具を取り扱うことができる。また、包装袋に直接接続具を取り付けることができるので誤接続の恐れもなく、接続具の接続後は接続具が包装袋から誤って外れる恐れもほとんどない。 As described above, according to the configuration of the packaging bag set of the present invention, the packaging bag containing the stored items can be easily connected without providing a special member such as a spout member, and the stored items of the packaging bag can be connected to the tube. It can be leaked. Further, when fixing the dispensing portion of the packaging bag to the connector, the insertion member can be easily inserted into the dispensing portion of the packaging bag and the outer winding member can be locked by a series of operations, so that one hand can be easily used. You can handle the fittings at. Further, since the connector can be directly attached to the packaging bag, there is no risk of erroneous connection, and there is almost no risk of the connector being accidentally detached from the packaging bag after the connector is connected.

尚、本実施の形態では、外巻部材２０１は、半円筒形の一対の分割体であって、閉状態では一対の分割体が円筒形を構成するものとして説明したが、一対の分割体の形状はこれに限定されず、例えば、半角筒状の一対の分割体であって、閉状態では一対の分割体が角筒形を構成してもよい。 In the present embodiment, the outer winding member 201 is described as a pair of semi-cylindrical divided bodies, and the pair of divided bodies constitutes a cylindrical shape in the closed state. The shape is not limited to this, and for example, it may be a pair of half-width cylindrical divided bodies, and the pair of divided bodies may form a square cylindrical shape in the closed state.

また、本実施の形態では、外巻部材２０３に設けられたロック部２０６は、凸状の部材と当該凸状の部材が嵌合可能な貫通孔を有する部材とから構成されるものとして説明したが、ロック部の構成はこれに限定されず、一対の分割体がロックされて固定されるものであればよい。 Further, in the present embodiment, the lock portion 206 provided on the outer winding member 203 has been described as being composed of a convex member and a member having a through hole into which the convex member can be fitted. However, the configuration of the lock portion is not limited to this, as long as the pair of divided bodies are locked and fixed.

また、本実施の形態では、差込部材２０３の連通孔２０７が２つに分岐する構成として説明したが、連通孔は、分岐せずに差込部材の外面に開口部を１つ形成するものでもよいし、３つ以上の任意の数に分岐するものでもよい。 Further, in the present embodiment, the communication hole 207 of the insertion member 203 has been described as having a structure in which the communication hole 207 is branched into two, but the communication hole is such that one opening is formed on the outer surface of the insertion member without branching. It may be a branch to any number of 3 or more.

また、本実施の形態では、差込部材２０３のフランジ部２０９が外巻部材２０１の溝部に嵌合することで外巻部材２０１が差込部材２０３に固定されるものとして説明したが、外巻部材が差込部材に固定される方法はこれに限定されず、外巻部材が差込部材の一方部に固定される構成であればよい。 Further, in the present embodiment, it has been described that the outer winding member 201 is fixed to the insertion member 203 by fitting the flange portion 209 of the insertion member 203 into the groove portion of the outer winding member 201. The method of fixing the member to the insertion member is not limited to this, and any configuration may be used as long as the outer winding member is fixed to one part of the insertion member.
