Description

本発明は、液状経腸栄養剤や各種流動食品、あるいはそれらを固形化、ゲル化またはゾル化した流動体を収容するための流動体収容容器に関する。   The present invention relates to a liquid container for containing a liquid enteral nutrient, various liquid foods, or a fluid obtained by solidifying, gelling, or solling them.

医療用の液状経腸栄養剤又は各種流動食品、あるいはそれらを固形化、ゲル化またはゾル化した流動体は、可撓性と液密性のある流動体収容容器に収容して保管、運搬されることが多い。ここで、流動体は空気に触れると酸化して成分が変質し、薬剤としての効能が低下又は劣化したり、味が変化したり、腐敗を招いたりする恐れがある。そのため、従来、液密性を有する材料及び酸素非透過性を有する材料で形成した容器本体を有する流動体収容容器が知られている（例えば、特許文献１参照）。   Liquid enteral nutrients for medical use or various liquid foods, or fluids obtained by solidifying, gelling, or solling them are stored and transported in flexible and liquid-tight fluid containers. Often. Here, when the fluid is exposed to the air, it oxidizes and the components are altered, and the efficacy as a drug may be reduced or deteriorated, the taste may be changed, or it may be spoiled. Therefore, conventionally, a fluid container having a container body formed of a liquid-tight material and an oxygen-impermeable material is known (see, for example, Patent Document 1).

しかし、上記特許文献１に記載の発明においては、注出部が樹脂製であり、酸素透過性を有するため、容器本体内部に収容された流動体は注出部から侵入した酸素によって徐々に酸化する恐れがある。一方、樹脂の内部にアルミ箔等の酸素非透過性物質を挟み込んで成形して注出部を形成することで、注出部からの酸素の侵入を防止することも考えられる。しかし、この構成においては、注出部の製造設備が複雑になると共に工程等も増加する結果、流動体収容容器のコストが高騰してしまうという問題がある。   However, in the invention described in Patent Document 1, since the pouring part is made of resin and has oxygen permeability, the fluid contained inside the container body is gradually oxidized by oxygen that has entered from the pouring part. There is a fear. On the other hand, it is also conceivable to prevent the intrusion of oxygen from the pouring portion by forming the pouring portion by sandwiching and molding an oxygen impermeable material such as an aluminum foil inside the resin. However, in this configuration, there is a problem that the cost of the fluid container rises as a result of the complexity of the manufacturing equipment for the extraction section and the increase in processes and the like.

この実施の形態の流動体収容容器１Ａは、医療用又は飲食用の流動体１００を収容する容器である。具体的には、この医療用又は飲食用の流動体１００は、液状経腸栄養剤や各種流動食品、あるいはそれらを固形化、ゲル化またはゾル化したものが考えられる。ただし、流動体１００はそれ以外のどのようなものであってもよい。   1 A of fluid accommodation containers of this embodiment are containers which accommodate the fluid 100 for medical use or food / drink. Specifically, the fluid 100 for medical use or food and drink may be a liquid enteral nutrient, various liquid foods, or those obtained by solidifying, gelling, or solling them. However, the fluid 100 may be anything other than that.

図１に示す通り、流動体収容容器１Ａは、容器本体１と、注出部２とを備える。   As shown in FIG. 1, the fluid container 1 </ b> A includes a container body 1 and a dispensing unit 2.

容器本体１は、正面視略矩形の袋状に形成された流動体収容部３と、流動体収容部３の一端部を封止する封止部４とを備える。流動体収容部３と封止部４で囲まれた内部には、流動体１００が収容される収容室５が形成されている。   The container body 1 includes a fluid container 3 formed in a substantially rectangular bag shape when viewed from the front, and a sealing unit 4 that seals one end of the fluid container 3. A storage chamber 5 in which the fluid 100 is stored is formed inside the fluid storage unit 3 and the sealing unit 4.

図２に示す通り、容器本体１の流動体収容部３は一対の「フィルム状の部材」としての第一のシート６，６によって形成され、封止部４は「フィルム状の部材」としての第二のシート７によって形成されている。   As shown in FIG. 2, the fluid housing part 3 of the container body 1 is formed by a pair of first sheets 6 and 6 as “film-like members”, and the sealing part 4 is a “film-like member”. It is formed by the second sheet 7.

第一のシート６は、正面視略矩形の可撓性のフィルム状の部材により形成されている。図３の（ａ）に示す通り、第一のシート６は、「接着層」及び「液密層」としての融着性樹脂フィルム８、剛性強化フィルム９ａ、「酸化防止層」としての光及び酸化防止フィルム９ｂ、「液密層」としての液密性フィルム１０、を積層して成る。対向する各フィルム８，９ａ，９ｂ，１０は図示せぬ接着剤で接合されている。 The first sheet 6 is formed of a flexible film member having a substantially rectangular shape when viewed from the front. As shown in FIG. 3 (a), the first sheet 6 includes a fusible resin film 8 as an “adhesive layer” and a “liquid-tight layer”, a rigidity reinforcing film 9a, and a light as an “antioxidation layer”. The antioxidant film 9b and the liquid-tight film 10 as a “liquid-tight layer” are laminated. The opposing films 8, 9a, 9b, 10 are joined with an adhesive (not shown).

融着性樹脂フィルム８は、例えばポリプロピレン（ＰＰ）等の樹脂によって形成される。融着性樹脂フィルム８は、流動体収容部３の状態において、後述するヒートプレスによる加熱・加圧加工により流動体収容部３自体及び封止部４に熱融着される。なお、ヒートプレスによる加熱・加圧加工以外でも、上記熱融着を実現できるものならばどのような加工を用いてもよい。また、融着性樹脂フィルム８は、収容室５に収容された流動体１００に対する液密性を有する。   The fusible resin film 8 is formed of a resin such as polypropylene (PP), for example. The fusible resin film 8 is heat-sealed to the fluid housing part 3 itself and the sealing part 4 by heating and pressurizing by heat press described later in the state of the fluid housing part 3. Any processing other than heat-pressing processing by heat press may be used as long as it can realize the above-mentioned heat fusion. Further, the fusible resin film 8 has liquid tightness with respect to the fluid 100 accommodated in the accommodation chamber 5.

剛性強化フィルム９ａは、ナイロン等、剛性の高い材質によって形成する。剛性強化フィルム９ａを積層させることで、外部から流動体収容部３に加えられる力や引っ張りに対する耐性を高めることができる。   The rigidity reinforcing film 9a is formed of a highly rigid material such as nylon. By laminating the rigid reinforcing film 9a, it is possible to increase the resistance to the force applied to the fluid accommodating part 3 and the tension from the outside.

光及び酸化防止フィルム９ｂは、アルミニウム等、酸素非透過性の材料によって形成されている。光及び酸化防止フィルム９ｂの材料は、酸素非透過性を有するものであれば、金属でも金属以外（例えば樹脂等）でもよい。   The light and antioxidant film 9b is made of an oxygen-impermeable material such as aluminum. The material of the light and the antioxidant film 9b may be a metal or other than a metal (for example, a resin or the like) as long as it has oxygen impermeability.

液密性フィルム１０は、ポリエチレンテレフタラート（ＰＥＴ）等、収容室５に収容された流動体１００や水に対する液密性を有する材質で形成されている。   The liquid-tight film 10 is formed of a material having liquid-tightness with respect to the fluid 100 stored in the storage chamber 5 or water, such as polyethylene terephthalate (PET).

第二のシート７は、正面視略矩形の可撓性のフィルム状の部材により形成されている。図３の（ｂ）に示す通り、第二のシート７は、第一のシート６と同様の融着性樹脂フィルム８、光及び酸化防止フィルム９ｂ、液密性フィルム１０に加え、更に、融着性樹脂フィルム８を積層して成る。即ち、第二のシート７によって形成される封止部４は、融着性樹脂フィルム８が表裏面にそれぞれ積層されて成る。この融着性樹脂フィルム８は、封止部４の状態において、ヒートプレスによる加熱・加圧加工により、流動体収容部３及び封止部４自身に熱融着される。また、第二のシート７の形成する、対向する各フィルム８，９，１０，８は図示せぬ接着剤で接合されている。   The second sheet 7 is formed of a flexible film member having a substantially rectangular shape when viewed from the front. As shown in FIG. 3 (b), the second sheet 7 includes a fusible resin film 8, a light and antioxidant film 9b, and a liquid-tight film 10 similar to those of the first sheet 6. The adhesive resin film 8 is laminated. That is, the sealing portion 4 formed by the second sheet 7 is formed by laminating the fusible resin film 8 on the front and back surfaces. This fusible resin film 8 is heat-sealed to the fluid accommodation part 3 and the sealing part 4 itself by heating and pressurizing with a heat press in the state of the sealing part 4. Further, the opposing films 8, 9, 10, 8 formed by the second sheet 7 are bonded with an adhesive (not shown).

第二のシート７は、封止部４として形成した状態において、後述するコネクタの先端部によって外部から押圧することで加圧箇所を破断させることが可能な強度に形成されている。   The 2nd sheet | seat 7 is formed in the intensity | strength which can break a pressurization location by pressing from the exterior by the front-end | tip part of the connector mentioned later in the state formed as the sealing part 4. FIG.

図２に示す通り、封止部４の長手方向に沿って略中央部には谷折り部１１が形成されている。封止部４は谷折り部１１で谷折りにされた状態で流動体収容部３の一端部に配設される。これにより、封止部４を形成する第二のシート７の端面１２は全て外側を向いた状態となり、第二のシート７の端面１２が収容室５に対向しないように形成されている。   As shown in FIG. 2, a valley fold portion 11 is formed at a substantially central portion along the longitudinal direction of the sealing portion 4. The sealing part 4 is disposed at one end of the fluid accommodating part 3 in a state where the sealing part 4 is folded at the valley fold part 11. Thereby, all the end surfaces 12 of the second sheet 7 forming the sealing portion 4 are directed outward, and the end surfaces 12 of the second sheet 7 are formed so as not to face the storage chamber 5.

注出部２は、ポリプロピレン等の樹脂によって形成されている。注出部２は、先端側に設けられた略円筒形の筒状部１３と、基端部に設けられた固定部１４とを備えている。筒状部１３は周囲に雄ねじ溝が設けられている。固定部１４は断面略菱形に形成され、内部の筒状部１３の延長上には円筒形の貫通孔１５が形成されている。   The extraction | pouring part 2 is formed with resin, such as a polypropylene. The extraction portion 2 includes a substantially cylindrical tubular portion 13 provided on the distal end side and a fixing portion 14 provided on the proximal end portion. The cylindrical portion 13 is provided with a male screw groove around it. The fixing part 14 is formed in a substantially rhombic cross section, and a cylindrical through hole 15 is formed on the extension of the internal cylindrical part 13.

注出部２の固定部１４の側面部は、上述の、谷折りにされた封止部４の間に、封止部４に囲繞された状態で保持される。図１に示すように、固定部１４の側面１４ａと基端面１４ｂ（貫通孔１５の開口部１６を除く）とには、封止部４が密着した状態で接合している。   The side surface portion of the fixing portion 14 of the extraction portion 2 is held in a state surrounded by the sealing portion 4 between the above-described sealing portions 4 that are valley-folded. As shown in FIG. 1, the sealing portion 4 is bonded to the side surface 14 a and the base end surface 14 b (excluding the opening portion 16 of the through hole 15) of the fixing portion 14 in close contact with each other.

このような構成により、収容室５に流動体１００を収容した容器本体１が保管された状態において、注出部２と収容室５とが封止部４によって離隔された状態となる。   With such a configuration, in a state where the container body 1 in which the fluid 100 is stored in the storage chamber 5 is stored, the extraction portion 2 and the storage chamber 5 are separated from each other by the sealing portion 4.

注出部２の筒状部１３には、キャップ１７が螺合されている。キャップ１７の内側には雌ねじ部（図示せず）が刻設されている。   A cap 17 is screwed into the cylindrical portion 13 of the dispensing portion 2. An internal thread portion (not shown) is engraved inside the cap 17.

次に、この実施の形態の流動体収容容器１Ａの製造工程について説明する。   Next, the manufacturing process of the fluid container 1A of this embodiment will be described.

＜第一の工程＞
まず、図４に示す通り、一対の第一のシート６，６を、それぞれの融着性樹脂フィルム８が対向するように配置させる。 <First step>
First, as shown in FIG. 4, the pair of first sheets 6 and 6 are arranged so that the respective fusible resin films 8 face each other.

＜第二の工程＞
次に、図５に示す通り、第二のシート７によって形成された封止部４を長手方向略中央部で谷折りし、谷折りにされた封止部４の間に注出部２の固定部１４を保持させる。容器本体１の注出部２の筒状部１３には、キャップ１７が螺合されても良い。 <Second step>
Next, as shown in FIG. 5, the sealing portion 4 formed by the second sheet 7 is valley-folded at a substantially central portion in the longitudinal direction, and the pouring portion 2 is sandwiched between the sealing portions 4 that are valley-folded. The fixing part 14 is held. A cap 17 may be screwed onto the cylindrical portion 13 of the dispensing portion 2 of the container body 1.

＜第三の工程＞
次に、第一の工程で対向された一対の第一のシート６，６の一端部側に前記第二の工程で得られた封止部４及び注出部２を配設し、対向する第一のシート６，６同士、及び、第一のシート６と封止部４とが接触した状態とする。この状態で、図６の（ａ）に示す通り、対向する第一のシート同士６，６の両側の周縁部１８，１８と、封止部４と第一のシート６の一端部とをそれぞれヒートプレス（図示せず）等によって加熱・加圧する。これにより、融着性樹脂フィルム８が融解したのちに固化し、加熱・加圧した箇所は熱融着される。これにより、収容室５が形成されるが、この段階では第一のシート６，６の基端側は熱融着されていない。 <Third step>
Next, the sealing portion 4 and the extraction portion 2 obtained in the second step are disposed and opposed to one end side of the pair of first sheets 6 and 6 opposed in the first step. The first sheets 6 and 6 and the first sheet 6 and the sealing portion 4 are in contact with each other. In this state, as shown to (a) of FIG. 6, the peripheral parts 18 and 18 of the both sides of the opposing 1st sheets 6 and 6, and the sealing part 4 and the one end part of the 1st sheet | seat 6 are respectively shown. Heat and pressurize with a heat press (not shown). Thereby, the meltable resin film 8 is solidified after being melted, and the heated / pressurized portion is thermally fused. As a result, the storage chamber 5 is formed. At this stage, the base end sides of the first sheets 6 and 6 are not thermally fused.

第三の工程の熱融着時において、ヒートプレスの温度は、融着性樹脂フィルムの融点より若干高い温度、例えば１７０〜２００℃に設定するのが望ましい。また、熱融着の際、固定部１４の側面と基端面（貫通孔１５の開口部１６を除く）とは、封止部４が密着した状態となるように加工する。   At the time of heat sealing in the third step, the temperature of the heat press is desirably set to a temperature slightly higher than the melting point of the fusible resin film, for example, 170 to 200 ° C. Further, at the time of heat-sealing, the side surface and the base end surface (excluding the opening portion 16 of the through hole 15) of the fixing portion 14 are processed so that the sealing portion 4 is in close contact.

容器本体１の注出部２の筒状部１３には、キャップ１７が螺合されても良い。   A cap 17 may be screwed onto the cylindrical portion 13 of the dispensing portion 2 of the container body 1.

以上に示す第一乃至第三の工程により、流動体収容容器１Ａが完成する。   The fluid container 1A is completed by the first to third steps described above.

この流動体収容容器１Ａの容器本体１においては、保管時及び輸送時において、収容室５の内部と注出部２とが封止部４によって隔離されている。そのため、注出部２が酸素透過性の材質で形成されていても、注出部２を透過した酸素の収容室５内部への侵入を、封止部４によって遮断できる。   In the container main body 1 of the fluid container 1A, the inside of the storage chamber 5 and the extraction part 2 are separated from each other by the sealing part 4 during storage and transportation. Therefore, even if the extraction part 2 is formed of an oxygen permeable material, the penetration of oxygen that has permeated the extraction part 2 into the storage chamber 5 can be blocked by the sealing part 4.

次に、この実施の形態の流動体収容容器１Ａの使用手順について説明する。   Next, the procedure for using the fluid container 1A of this embodiment will be described.

流動体収容容器１Ａ内部の流動体１００の使用者は、流動体収容容器１Ａのキャップ１７を外し、図７に示す投与器具２０を注出部２の筒状部１３に接合させる。この投与器具２０には、円筒形のコネクタ２１が設けられている。コネクタ２１の先端部２２は尖った形状であり、コネクタ２１が筒状部１３の内部に押し込まれると、先端部２２が貫通孔１５の開口部１６に位置する封止部４に当接し、この当接箇所の封止部４が先端部２２による外部からの力によって破断する。投与器具２０はチューブ（図示せず）を介して図示せぬ他端部に胃瘻用コネクタが設けられており、この胃瘻用コネクタを患者の胃瘻に接続する。この状態で、収容室５に収容された流動体１００は注出部２の貫通孔１５及び筒状部１３を通過して外部に注出されて、人体内部に供給される。   The user of the fluid 100 inside the fluid container 1A removes the cap 17 of the fluid container 1A, and joins the administration device 20 shown in FIG. The administration device 20 is provided with a cylindrical connector 21. The distal end portion 22 of the connector 21 has a sharp shape, and when the connector 21 is pushed into the cylindrical portion 13, the distal end portion 22 abuts on the sealing portion 4 located at the opening portion 16 of the through hole 15. The sealing portion 4 at the contact portion is broken by an external force by the tip portion 22. The administration device 20 is provided with a gastrostomy connector at the other end (not shown) via a tube (not shown), and this gastrostomy connector is connected to the patient's gastrostomy. In this state, the fluid 100 accommodated in the accommodating chamber 5 passes through the through-hole 15 and the cylindrical portion 13 of the extraction portion 2 and is extracted to the outside and supplied into the human body.

即ち、収容室５に収容された流動体１００が酸素に触れる時間は、封止部４が破断されてから胃瘻用チューブ等で人体内部に供給されるまでのごくわずかな時間のみに限られる。このため、流動体１００の酸化による変質は確実に防止される。   That is, the time during which the fluid 100 accommodated in the accommodation chamber 5 is in contact with oxygen is limited to a very short time from when the sealing portion 4 is broken to when the fluid 100 is supplied into the human body with a gastrostomy tube or the like. . For this reason, the alteration of the fluid 100 due to oxidation is reliably prevented.

以上、この実施の形態においては、流動体収容部３及び封止部４自体に熱融着される封止部４は、光及び酸化防止フィルム９ｂを積層して成り、谷折りにされた封止部４の間に注出部２の固定部１４の側面部が保持されて、収容室５に流動体１００を収容した容器本体１が保管された状態において注出部２と収容室５とが封止部４によって離隔された状態とされることにより、流動体１００を収容した容器本体１が保管された状態で、注出部２を透過した酸素が収容室５内部に侵入することを防ぐことができる。そして、注出部２の材質の如何にかかわらず注出部２から収容室５への酸素の侵入を防止できるので、注出部２を樹脂等酸素透過性の材質によって低コストで簡易に形成できる。これにより、流動体収容容器１Ａを、低コストで簡易に製造できて、収容室５内部に収容された流動体１００の変質を確実に防止できる。   As described above, in this embodiment, the sealing portion 4 that is heat-sealed to the fluid accommodating portion 3 and the sealing portion 4 itself is formed by laminating the light and the antioxidant film 9b, and is a valley-folded seal. In the state where the side surface portion of the fixing portion 14 of the extraction portion 2 is held between the stopper portions 4 and the container body 1 storing the fluid 100 is stored in the storage chamber 5, the extraction portion 2 and the storage chamber 5 Are separated from each other by the sealing portion 4, so that the oxygen that has permeated the extraction portion 2 enters the inside of the accommodation chamber 5 in a state where the container body 1 containing the fluid 100 is stored. Can be prevented. In addition, since oxygen can be prevented from entering the storage chamber 5 from the extraction portion 2 regardless of the material of the extraction portion 2, the extraction portion 2 is easily formed at a low cost by an oxygen-permeable material such as resin. it can. Thereby, 1 A of fluid accommodation containers can be manufactured easily at low cost, and the quality change of the fluid 100 accommodated in the storage chamber 5 can be prevented reliably.

この実施の形態においては、封止部４は、注出部２の筒状部１３の延長上の開口部１６に面する部分が外部からの加圧で破断可能に形成されたことにより、流動体を使用する際、開口部１６に面する封止部４を破断させて、流動体１００を筒状部１３から注出させることができるため、流動体１００を使用する際の取り扱いを容易にできる。   In this embodiment, the sealing portion 4 is formed so that the portion facing the opening portion 16 on the extension of the tubular portion 13 of the extraction portion 2 is formed to be ruptured by external pressure. When the body is used, the sealing part 4 facing the opening 16 can be broken, and the fluid 100 can be poured out from the cylindrical part 13, so that the handling when using the fluid 100 is easy. it can.

この実施の形態においては、谷折りされた封止部４は、注出部２以外の部分全体にわたってそれぞれ密着させて接着されたことにより、注出部２と封止部４との接合部分周辺に気泡が形成されることや、この気泡中の空気が収容室５内部に漏れ出す事態を防止できる。これにより、収容室５内部に収容された流動体１００の変質を一層確実に防止できる。   In this embodiment, the valley-folded sealing portion 4 is adhered and adhered to the entire portion other than the pouring portion 2, so that the periphery of the joint portion between the pouring portion 2 and the sealing portion 4. It is possible to prevent the formation of bubbles and the situation where air in the bubbles leaks into the storage chamber 5. Thereby, the quality change of the fluid 100 accommodated in the accommodating chamber 5 can be prevented more reliably.

この実施の形態においては、封止部４を形成する融着性樹脂フィルム８は、封止部４を形成する第二のシート７の表裏面それぞれに積層されてなることにより、封止部４の表裏面それぞれを熱融着させることができるので、流動体収容容器１Ａを容易に加工形成できる。   In this embodiment, the fusible resin film 8 that forms the sealing portion 4 is laminated on each of the front and back surfaces of the second sheet 7 that forms the sealing portion 4. Since the front and back surfaces can be heat-sealed, the fluid container 1A can be easily processed and formed.

この実施の形態においては、封止部４の「接着層」を形成する融着性樹脂フィルム８は、「液密層」でもあることにより、封止部４を簡易に構成しつつ、流動体収容容器１Ａを容易に加工形成できる。   In this embodiment, the fusible resin film 8 forming the “adhesive layer” of the sealing portion 4 is also a “liquid-tight layer”, so that the fluid can be formed while the sealing portion 4 is simply configured. The container 1A can be easily processed and formed.

なお、この実施の形態においては、流動体収容部３を形成する第一のシート６を融着性樹脂フィルム８、光及び酸化防止フィルム９ｂ、液密性フィルム１０を積層して成るものとし、封止部４を形成する第二のシート７を融着性樹脂フィルム８、光及び酸化防止フィルム９ｂ、液密性フィルム１０、融着性樹脂フィルム８を積層して成るものとした。しかし、これに限らず、第一のシート６及び第二のシート７の少なくとも何れか一方に他のフィルムを積層させてもよい。例えば、第一のシート６及び第二のシート７の少なくとも何れか一方にナイロン樹脂製のフィルムを更に積層させ、耐久性を向上させることが考えられる。   In this embodiment, the first sheet 6 forming the fluid container 3 is formed by laminating a fusible resin film 8, a light and antioxidant film 9b, and a liquid-tight film 10. The second sheet 7 forming the sealing portion 4 was formed by laminating a fusible resin film 8, a light and antioxidant film 9b, a liquid-tight film 10, and a fusible resin film 8. However, the present invention is not limited to this, and another film may be laminated on at least one of the first sheet 6 and the second sheet 7. For example, it is conceivable that a nylon resin film is further laminated on at least one of the first sheet 6 and the second sheet 7 to improve durability.

また、この実施の形態においては、融着性樹脂フィルム８を「接着層」及び「液密層」として機能させる構成とした。しかし、これに限らず、接着層としてのみ機能する材質で融着性樹脂フィルムを形成してもよい。   In this embodiment, the fusible resin film 8 is configured to function as an “adhesive layer” and a “liquid-tight layer”. However, the present invention is not limited thereto, and the fusible resin film may be formed of a material that functions only as an adhesive layer.

上記実施の形態は本発明の例示であり、本発明が上記実施の形態のみに限定されることを意味するものではないことは、いうまでもない。   The above embodiment is an exemplification of the present invention, and it is needless to say that the present invention is not limited to the above embodiment.
