Description
本発明は、薬液収容容器、薬液供給部材、薬液供給装置およびその製造方法に関する。 The present invention relates to a chemical liquid storage container, a chemical liquid supply member, a chemical liquid supply device, and a manufacturing method thereof.
特許文献１には、薬品が充填される容器のスパウト部に逆流防止弁構造を持つ雌部材を設け、雌部材を開閉するプラグと組み合わせる連結システムが開示されている。この連結システムは、使用時にはプラグを雌部材に挿入して雌部材の逆流防止弁を開き、使用を中断する際にはプラグを雌部材から抜いて逆流防止弁を閉じることができる。 Patent Document 1 discloses a connection system in which a female member having a check valve structure is provided in a spout portion of a container filled with a medicine, and the female member is combined with a plug that opens and closes the female member. This coupling system allows the plug to be inserted into the female member to open the female member's check valve when in use, and the plug to be removed from the female member to close the check valve when discontinued use.
逆流防止弁構造を有する機構の場合、逆流防止弁の分だけスパウト部の開口が小さくなるため、薬品の充填が容易ではない。また、特殊な逆流防止弁が必要となるため、コスト高となる。さらに、ユーザがプラグを抜き差しする際に、容器内の薬品に触れてしまうおそれがある。 In the case of a mechanism having a non-return valve structure, the opening of the spout portion becomes smaller by the amount of the non-return valve, making it difficult to fill with chemicals. Additionally, a special check valve is required, resulting in high costs. Furthermore, when the user inserts or removes the plug, there is a risk that the user may come into contact with the chemical inside the container.

以下、本発明に係る実施形態について、図面を参照しながら具体的に説明する。 Embodiments according to the present invention will be specifically described below with reference to the drawings.
図１は、一実施形態に係る薬液供給装置の概略正面図である。薬液供給装置は、薬液を収容した薬液収容容器１００と、これに取り付けられた薬液供給部材２００とを備える。 FIG. 1 is a schematic front view of a chemical liquid supply device according to an embodiment. The drug solution supply device includes a drug solution storage container 100 containing a drug solution, and a drug solution supply member 200 attached to the container.
一例として、薬液は洗浄液であり、薬液供給装置のユーザは店舗スタッフである。また、薬液供給部材２００はユーザ店舗の設備に常設されている。そして、薬液が収容された状態で流通する薬液収容容器１００を薬液供給部材２００に取り付けることで、図１に示す薬液供給装置が製造される。薬液収容容器１００はユーザによるリクローズや再充填を想定しておらず、薬液を使い切ると使用済の薬液収容容器１００を取り外して廃棄し、新たな薬液収容容器１００に薬液供給部材２００を取り付ける。 As an example, the chemical liquid is a cleaning liquid, and the user of the chemical liquid supply device is a store staff member. Further, the chemical solution supply member 200 is permanently installed in the equipment of the user's store. Then, by attaching the chemical solution storage container 100, which circulates the drug solution therein, to the drug solution supply member 200, the drug solution supply device shown in FIG. 1 is manufactured. The chemical liquid storage container 100 is not intended to be reclosed or refilled by the user, and when the chemical liquid is used up, the used chemical liquid storage container 100 is removed and discarded, and the chemical liquid supply member 200 is attached to a new chemical liquid storage container 100.
まずは、薬液収容容器１００について説明する。
図２Ａは、出荷状態（すなわち、薬液供給部材２００が取り付けられる前）の薬液収容容器１００の概略正面図である。薬液収容容器１００は、パウチ本体１と、スパウト部２と、内栓３（図２Ａには見えない）と、キャップ４とを備えている。なお、図２Ｂは、図２Ａのキャップ４を外した状態を示す図である。また、図２Ｃは、パウチ本体１およびスパウト部２から内栓３およびキャップ４を取り外した状態を示す分解図である。
First, the chemical liquid storage container 100 will be explained.
FIG. 2A is a schematic front view of the chemical liquid storage container 100 in a shipping state (that is, before the chemical liquid supply member 200 is attached). The drug solution storage container 100 includes a pouch body 1, a spout portion 2, an inner stopper 3 (not visible in FIG. 2A), and a cap 4. Note that FIG. 2B is a diagram showing a state in which the cap 4 of FIG. 2A is removed. Moreover, FIG. 2C is an exploded view showing a state in which the inner plug 3 and cap 4 are removed from the pouch body 1 and the spout part 2.
パウチ本体１は液体状の薬液（不図示）を収容する。パウチ本体１の形状に特に制限はなく、側面に折り込みが設けられたガゼットタイプ、底面に折り込みが設けられたスタンディングタイプ、折り込みが設けられない平袋タイプなどであってよい。パウチ本体１は、例えば薬液耐性を有し、かつ、柔軟に変形可能なポリオレフィン系のＰＥ（ポリエチレン）、ＰＰ（ポリプロピレン）などの単層フィルム、また、プラスチックフィルムやアルミ箔など複数素材を貼合したラミネートフィルム製であり、薬液を収容していない状態では折り畳んで体積を小さくすることができ、薬液が入ることで体積が大きくなるのが望ましい。もちろん、パウチ本体１は硬い部材で形成されて、薬液の有無にかかわらず一定の形状であってもよい。 The pouch body 1 contains a liquid drug solution (not shown). The shape of the pouch body 1 is not particularly limited, and may be a gusset type with a fold on the side, a standing type with a fold on the bottom, a flat bag type without a fold, or the like. The pouch body 1 is made of, for example, a single-layer film made of polyolefin-based PE (polyethylene) or PP (polypropylene) that is resistant to chemical solutions and can be flexibly deformed, or laminated with multiple materials such as plastic film and aluminum foil. It is made of a laminated film that can be folded to reduce its volume when it does not contain a chemical solution, and it is desirable that the volume increases when it contains a drug solution. Of course, the pouch main body 1 may be formed of a hard member and may have a constant shape regardless of the presence or absence of the drug solution.
そして、パウチ本体１の上方には開口部１ａが設けられる。この開口部１ａにスパウト部２が設けられる。パウチ本体１およびスパウト部２は、両者が予め一体となった汎用品であってよく、これによりコストを抑えることができる。なお、本明細書では、便宜上、特に断らない限り、パウチ本体１における開口部１ａが設けられる側を「上」と定義している。 An opening 1a is provided above the pouch main body 1. A spout portion 2 is provided in this opening portion 1a. The pouch main body 1 and the spout portion 2 may be a general-purpose product that is integrated in advance, thereby reducing costs. In this specification, for convenience, unless otherwise specified, the side of the pouch body 1 where the opening 1a is provided is defined as "upper".
図３は、スパウト部２近傍の拡大断面図である。図３を参照しつつ、スパウト部２、内栓３およびキャップ４について説明する。 FIG. 3 is an enlarged cross-sectional view of the spout portion 2 and its vicinity. The spout portion 2, inner plug 3, and cap 4 will be explained with reference to FIG.
スパウト部２は、環状部材２１と、円筒部材２２とを有する。スパウト部２はパウチ本体１の開口部１ａを貫通しており、少なくとも環状部材２１の底面２１ａはパウチ本体１内にある。そして、円筒部材２２は環状部材２１の上面から上方に向かって延びている。円筒部材２２の外周面には雄ネジ２２ａが設けられている。さらに、キャップ４をスパウト部２に嵌め殺しするための円環部２３が円筒部材２２に設けられてもよい。スパウト部２は、例えばＰＥ（ポリエチレン）あるいはＰＰ（ポリプロピレン）製であり、硬くて変形しにくい部材である。 The spout portion 2 includes an annular member 21 and a cylindrical member 22. The spout portion 2 passes through the opening 1a of the pouch body 1, and at least the bottom surface 21a of the annular member 21 is inside the pouch body 1. The cylindrical member 22 extends upward from the upper surface of the annular member 21. A male screw 22a is provided on the outer peripheral surface of the cylindrical member 22. Further, the cylindrical member 22 may be provided with an annular portion 23 for fitting the cap 4 into the spout portion 2. The spout portion 2 is made of, for example, PE (polyethylene) or PP (polypropylene), and is a hard member that does not easily deform.
内栓３はスパウト部２の内側に嵌められる。内栓３は、円筒部材３１と、肩部３２と、ツメ３３と、開口機構３４とを有する。ここで、内栓３の概略側面図、概略上面図、概略下面図を図４Ａ～図４Ｃにそれぞれ示す。 The inner plug 3 is fitted inside the spout portion 2. The inner plug 3 has a cylindrical member 31, a shoulder portion 32, a claw 33, and an opening mechanism 34. Here, a schematic side view, a schematic top view, and a schematic bottom view of the inner plug 3 are shown in FIGS. 4A to 4C, respectively.
図３に示すように、円筒部材３１の外径は、スパウト部２における円筒部材２２の内径よりわずかに小さく、円筒部材３１の外周面が円筒部材２２の内周面に密着する。これにより、薬液が意図せず外部に漏れるのを抑えることができる。また、図４Ａおよび図４Ｃに示すように、円筒部材３１の下方には切り込み３１ａが設けられてよい。これにより、内栓３を円筒部材２２に挿入しやすくなる。 As shown in FIG. 3, the outer diameter of the cylindrical member 31 is slightly smaller than the inner diameter of the cylindrical member 22 in the spout portion 2, and the outer peripheral surface of the cylindrical member 31 is in close contact with the inner peripheral surface of the cylindrical member 22. This can prevent the chemical from unintentionally leaking to the outside. Further, as shown in FIGS. 4A and 4C, a cut 31a may be provided below the cylindrical member 31. This makes it easier to insert the inner plug 3 into the cylindrical member 22.
肩部３２は円環状であり、例えば円筒部材３１の上端から外側に向かって水平方向に延びている（図３参照）。したがって、肩部３２の外径は円筒部材３１の外径より大きい。そして、肩部３２はスパウト部２における円筒部材２２の上部（スパウト部２の長手方向の上端部）に乗っている。言い換えると、円筒部材２２の上端面上に肩部３２の下面が位置している。これにより、内栓３がスパウト部２から抜けてパウチ本体１内に落ちることなくスパウト部２内の内側に留まるとともに、薬液が意図せず外部に漏れるのを抑えることができる。 The shoulder portion 32 has an annular shape, and extends horizontally outward from the upper end of the cylindrical member 31, for example (see FIG. 3). Therefore, the outer diameter of the shoulder portion 32 is larger than the outer diameter of the cylindrical member 31. The shoulder portion 32 rests on the upper portion of the cylindrical member 22 in the spout portion 2 (the upper end portion in the longitudinal direction of the spout portion 2). In other words, the lower surface of the shoulder portion 32 is located on the upper end surface of the cylindrical member 22. Thereby, the inner stopper 3 does not fall out of the spout part 2 and fall into the pouch body 1, but stays inside the spout part 2, and it is possible to prevent the chemical solution from unintentionally leaking to the outside.
ツメ３３は、例えば円筒部材３１の下端から外側に向かって延びている。ツメ３３の側面図および斜視図を図４Ｄおよび図４Ｅに示す。ツメ３３は、円筒部材３１から外側に向かって水平方向に延びる受け皿面３３ａと、下方に向かって尖ったテーパー面３３ｂとを有する。図３に示すように、受け皿面３３ａがスパウト部２の環状部材２１の底面２１ａ（スパウト部２の長手方向の下端部）に引っかかることで、内栓３がスパウト部２から上方に抜けるのを抑えることができる。また、テーパー面３３ｂを設けることで、内栓３を円筒部材２２に挿入しやすくなる。 The claw 33 extends outward from the lower end of the cylindrical member 31, for example. A side view and a perspective view of the claw 33 are shown in FIGS. 4D and 4E. The claw 33 has a saucer surface 33a extending horizontally outward from the cylindrical member 31, and a tapered surface 33b pointing downward. As shown in FIG. 3, the tray surface 33a is caught on the bottom surface 21a of the annular member 21 of the spout section 2 (lower end in the longitudinal direction of the spout section 2), thereby preventing the inner plug 3 from coming out upward from the spout section 2. It can be suppressed. Further, by providing the tapered surface 33b, it becomes easier to insert the inner plug 3 into the cylindrical member 22.
図３に示すように、開口機構３４は円筒部材３１の内部に設けられる。開口機構３４は、出荷状態（ユーザが薬液を使用する前）は蓋３４ｂがあって開口しておらず、パウチ本体１内の薬液がスパウト部２から漏れ出るのを抑える。そのため、スパウト部２に逆流防止弁を設けなくてもよい。ユーザが薬液を使用する時には、開口機構３４は、蓋３４ｂの少なくとも一部が外れることによって開口部３４ａが形成され、パウチ本体１内の薬液がスパウト部２から排出される。 As shown in FIG. 3, the opening mechanism 34 is provided inside the cylindrical member 31. In the shipping state (before the user uses the medicinal solution), the opening mechanism 34 has a lid 34b and is not opened, which prevents the medicinal solution in the pouch body 1 from leaking out from the spout portion 2. Therefore, it is not necessary to provide the spout portion 2 with a check valve. When a user uses the medicinal solution, the opening mechanism 34 forms an opening 34a by removing at least a portion of the lid 34b, and the medicinal solution in the pouch body 1 is discharged from the spout portion 2.
開口機構３４の一例として、開口機構３４は、開口部３４ａに設けられた円板状の蓋３４ｂと、蓋３４ｂを円筒部材３１に固定する固定部材３４ｃとを有する。そして、使用時には、ユーザがプラグ（後述）で蓋３４ｂを下方に向かって押圧することにより、蓋３４ｂが固定部材３４ｃから外れて開口機構３４に開口部３４ａが形成される。なお、蓋３４ｂが固定部材３４ｃから完全に外れると、蓋３４ｂが薬液中に落下する。この点が不都合であれば、蓋３４ｂの一部のみが固定部材３４ｃから外れるようにする（ハッチ式）ことで、蓋３４ｂが薬液中に落下することなく開口部３４ａを形成できる。 As an example of the opening mechanism 34, the opening mechanism 34 includes a disc-shaped lid 34b provided in the opening 34a, and a fixing member 34c that fixes the lid 34b to the cylindrical member 31. In use, when the user presses the lid 34b downward with a plug (described later), the lid 34b comes off from the fixing member 34c, and an opening 34a is formed in the opening mechanism 34. Note that when the lid 34b is completely removed from the fixing member 34c, the lid 34b falls into the chemical solution. If this point is inconvenient, by allowing only a portion of the lid 34b to come off the fixing member 34c (hatch type), the opening 34a can be formed without the lid 34b falling into the chemical solution.
キャップ４はスパウト部２の上部外側を覆っている。具体的には、キャップ４の内周面に設けられた雌ネジが、スパウト部２の外周面に設けられた雄ネジ２２ａと係合することで、キャップ４がスパウト部２に嵌まる。また、キャップ４の上面から下方に延びる円環部４１が設けられてもよい。円環部４１の外径は内栓３の円筒部材３１の内径よりわずかに小さく、これにより内栓３をより強固に固定できる。 The cap 4 covers the upper outer side of the spout portion 2. Specifically, the cap 4 is fitted into the spout portion 2 by the female thread provided on the inner peripheral surface of the cap 4 engaging with the male thread 22a provided on the outer peripheral surface of the spout portion 2 . Further, an annular portion 41 extending downward from the upper surface of the cap 4 may be provided. The outer diameter of the annular portion 41 is slightly smaller than the inner diameter of the cylindrical member 31 of the inner plug 3, so that the inner plug 3 can be fixed more firmly.
このような薬液収容容器１００は以下のようにして製造される。まず、内栓３およびキャップ４が外された状態（図２Ｃ参照）で、スパウト部２を介して所望の薬液をパウチ本体１内に充填する。スパウト部２内に逆流防止弁がないので、薬液の充填が容易である。 Such a chemical solution storage container 100 is manufactured as follows. First, with the inner stopper 3 and cap 4 removed (see FIG. 2C), a desired chemical solution is filled into the pouch body 1 through the spout portion 2. Since there is no check valve in the spout section 2, filling of the chemical solution is easy.
その後、スパウト部２の内側に内栓３を挿入し（図２Ｂ参照）、密栓する。次いで、キャップ４をスパウト部２に締め込み（図２Ａ参照）、必要に応じて嵌め殺しとする。この状態でユーザに出荷される。なお、内栓３によって密閉されて薬液がパウチ本体１から出ないのであれば、キャップ４を設けなくてもよい。 Thereafter, the inner plug 3 is inserted inside the spout portion 2 (see FIG. 2B) and sealed tightly. Next, the cap 4 is tightened onto the spout portion 2 (see FIG. 2A), and the cap 4 is tightened if necessary. It is shipped to users in this state. Note that if the inner stopper 3 seals the pouch body 1 and the medicinal solution does not come out of the pouch body 1, the cap 4 may not be provided.
続いて、薬液供給部材２００について説明する。
図５Ａは、薬液供給部材２００の概略平面図である。図５Ｂは、薬液供給部材２００を斜め下から見た図である。図５Ｃは、薬液供給部材２００を下方から見た図である。薬液供給部材２００は、プラグ５と、チューブ６と、プラグキャップ７とを有する。
Next, the chemical liquid supply member 200 will be explained.
FIG. 5A is a schematic plan view of the chemical liquid supply member 200. FIG. 5B is a diagram of the chemical liquid supply member 200 viewed diagonally from below. FIG. 5C is a diagram of the chemical solution supply member 200 viewed from below. The chemical supply member 200 includes a plug 5, a tube 6, and a plug cap 7.
プラグ５は、尖った先端部５１と、薬液流路５２とを有する。先端部５１（の先端および／または側面）には孔５１ａが設けられ、この孔５１ａを通って薬液が薬液流路５２内に流入できる。薬液流路５２はプラグキャップ７の上面を貫通し、上部においてチューブ６と接続されている。また、薬液流路５２には、シール部材としてのＯリング５３が嵌められている。プラグキャップ７の中心にプラグ５の薬液流路５２が位置しており、薬液流路５２はプラグキャップ７に固定されている。そして、プラグキャップ７の内周面には、雌ネジ７ａが設けられる。 The plug 5 has a sharp tip 51 and a chemical liquid channel 52. A hole 51a is provided in (the tip and/or the side surface of) the distal end portion 51, and a medical solution can flow into the medical solution channel 52 through this hole 51a. The chemical fluid channel 52 passes through the top surface of the plug cap 7 and is connected to the tube 6 at the top. Further, an O-ring 53 as a sealing member is fitted into the chemical fluid channel 52. A chemical liquid flow path 52 of the plug 5 is located at the center of the plug cap 7, and the chemical liquid flow path 52 is fixed to the plug cap 7. A female thread 7a is provided on the inner peripheral surface of the plug cap 7.
薬液の使用時、ユーザは薬液収容容器１００からキャップ４を外し（図２Ｂの状態）、薬液供給部材２００を取り付ける。具体的には、薬液供給部材２００のプラグキャップ７の雌ネジ７ａを、薬液収容容器１００におけるスパウト部２の外面の雄ネジ２２ａに締め込み、薬液収容容器１００と薬液供給部材２００とを固定する。 When using a drug solution, the user removes the cap 4 from the drug solution storage container 100 (the state shown in FIG. 2B) and attaches the drug solution supply member 200. Specifically, the female thread 7a of the plug cap 7 of the chemical liquid supply member 200 is tightened into the external thread 22a of the spout portion 2 of the chemical liquid storage container 100 to fix the chemical liquid storage container 100 and the chemical liquid supply member 200. .
図６Ａは、薬液収容容器１００に薬液供給部材２００を取り付けた状態におけるスパウト部２近傍の拡大断面図である。図示のように、薬液供給部材２００を薬液収容容器１００に取り付けることで、プラグ５の先端部５１が内栓３の蓋３４ｂを押圧し、開口部３４ａが形成される（すなわち、先端部５１は蓋３４ｂを押圧して開口部３４ａを形成できる程度に尖っていればよい）。図６Ｂに、プラグ５の先端部５１によって内栓３に開口部３４ａが形成された様子を示す。以下、より詳しく説明する。 FIG. 6A is an enlarged sectional view of the vicinity of the spout portion 2 in a state where the chemical liquid supply member 200 is attached to the chemical liquid storage container 100. As shown in the figure, by attaching the drug solution supply member 200 to the drug solution storage container 100, the tip 51 of the plug 5 presses the lid 34b of the inner stopper 3, and an opening 34a is formed (that is, the tip 51 It only needs to be sharp enough to press the lid 34b to form the opening 34a). FIG. 6B shows how the opening 34a is formed in the inner plug 3 by the tip 51 of the plug 5. This will be explained in more detail below.
図６Ａに示すように、プラグ５は開口機構３４に到達する長さを有する。そのため、薬液供給部材２００のプラグキャップ７の雌ネジ７ａをスパウト部２の雄ネジ２２ａに締め込むことで、それほど強い力を加えなくても、真っすぐにプラグ５の先端部５１が開口機構３４の蓋３４ｂを押圧し、さらには開口部３４ａを貫通する。その結果、先端部５１に形成された孔５１ａは開口部３４ａより下方に位置する。また、Ｏリング５３が内栓３（における円筒部材３１）の内面に密着する。 As shown in FIG. 6A, the plug 5 has a length that reaches the opening mechanism 34. Therefore, by tightening the female screw 7a of the plug cap 7 of the chemical solution supply member 200 into the male screw 22a of the spout portion 2, the tip 51 of the plug 5 can be straightly inserted into the opening mechanism 34 without applying much force. The lid 34b is pressed and further the opening 34a is penetrated. As a result, the hole 51a formed in the tip 51 is located below the opening 34a. Further, the O-ring 53 is in close contact with the inner surface of the inner plug 3 (the cylindrical member 31 therein).
図７Ａは、薬液供給装置の使用状態を示す図である。また、図７Ｂは、薬液供給装置の使用時におけるスパウト部２近傍の拡大断面図である。これらの図に示すように、使用時には、薬液供給装置が吊り下げられてパウチ本体１の開口部１ａが下向きとなる。そして、チューブ６の先に設けたポンプ（不図示）で負圧を生成することにより、パウチ本体１内の薬液が吸引され、プラグ５の孔５１ａおよび内栓３に形成された開口部３４ａを通り、薬液流路５２を通り、さらにチューブ６を通って薬液が供給される（図７Ｂ参照）。 FIG. 7A is a diagram showing the usage state of the chemical solution supply device. Further, FIG. 7B is an enlarged cross-sectional view of the vicinity of the spout portion 2 when the chemical liquid supply device is in use. As shown in these figures, when in use, the drug supply device is suspended so that the opening 1a of the pouch body 1 faces downward. Then, by generating negative pressure with a pump (not shown) provided at the tip of the tube 6, the medicinal liquid in the pouch body 1 is sucked, and the hole 51a of the plug 5 and the opening 34a formed in the inner stopper 3 are sucked. The chemical liquid is supplied through the chemical liquid channel 52, and further through the tube 6 (see FIG. 7B).
なお、Ｏリング５３が内栓３における円筒部材３１の内面に密着するため、薬液が薬液流路５２の外側を通ってチューブ６の外側から漏れるのを抑えられる。 In addition, since the O-ring 53 is in close contact with the inner surface of the cylindrical member 31 in the inner stopper 3, leakage of the medical solution from the outside of the tube 6 through the outside of the medical solution flow path 52 can be suppressed.
また、パウチ本体１内には、予め薬液のみならず空気が含まれているのが望ましい。薬液を使い切ったあとにもポンプによって吸引が行われるが、その際のポンプに対する負荷を低減するためである。また、チューブ６の近傍に屈折率を検知するセンサを設けることで、チューブ６に薬液が流れているか、薬液を使い切ってしまって空気が流れているかを検知できる。 Further, it is desirable that not only the drug solution but also air be contained in the pouch body 1 in advance. The pump performs suction even after the chemical solution is used up, and this is to reduce the load on the pump at that time. Furthermore, by providing a sensor that detects the refractive index near the tube 6, it is possible to detect whether the chemical liquid is flowing in the tube 6 or whether the chemical liquid has been used up and air is flowing.
本薬液供給装置は、リクローズや薬液のみの交換を想定しておらず、薬液を使い切った時点で薬液収容容器１００を交換する。薬液を使い切った状態で交換するため、ユーザは薬液に触れることなく、交換作業を安全に行うことができる。 This chemical solution supply device is not intended for re-closing or replacing only the chemical solution, but replaces the chemical solution storage container 100 when the chemical solution is used up. Since the chemical solution is replaced when it is used up, the user can safely perform the replacement work without touching the chemical solution.
なお、パウチ本体１内に残ってしまう薬液の量をできるだけ少なくすべく、図７Ｂに示すように、内栓３の開口機構３４に形成される開口部３４ａは、スパウト部２における環状部材２１の底面２１ａ（使用状態の図７では上面として示される）よりプラグキャップ７側（使用時における下方）にあるのが望ましい。ただし、多少（例えば数ｍｍ～１０ｍｍ程度）であれば、底面２１ａよりプラグキャップ７の反対側（使用時における上方）であってもよい。 In addition, in order to minimize the amount of drug remaining in the pouch body 1, as shown in FIG. It is desirable that it be located closer to the plug cap 7 (lower in use) than the bottom surface 21a (shown as the top surface in FIG. 7 in use). However, it may be on the opposite side of the plug cap 7 from the bottom surface 21a (above during use) as long as it is a little (for example, about several mm to 10 mm).
また、開口部３４ａは、スパウト部２の雄ネジ２２ａより環状部材２１側（パウチ本体１側、使用時における上方）にあるのが望ましい。プラグキャップ７と一体化しているプラグ５に配置されているＯリング５３が、スパウト部２の雄ネジ２２ａと、プラグキャップ７の雌ネジ７ａとを締め込み開始する段階で、液漏れしない位置となっているのが望ましく、そのＯリング５３よりも更にパウチ本体１の内側方向に位置する開口部３４ａは、必然的にスパウト部２の雄ネジ２２ａより環状部材２１側となるためである。 Further, it is desirable that the opening 34a be located closer to the annular member 21 (on the pouch body 1 side, above when in use) than the male thread 22a of the spout portion 2. When the O-ring 53 disposed on the plug 5 integrated with the plug cap 7 starts tightening the male thread 22a of the spout part 2 and the female thread 7a of the plug cap 7, the O-ring 53 is placed in a position where no liquid leaks. This is because the opening 34a located further inward of the pouch body 1 than the O-ring 53 is necessarily closer to the annular member 21 than the male thread 22a of the spout portion 2.
本実施形態によれば、スパウト部２に逆流防止弁を設ける必要がない。そのため、スパウト部２の開口が大きくなり、薬品の充填が容易となる。また、特殊な逆流防止弁が不要であるし、汎用品のパウチ本体１およびスパウト部２を利用できるため、コストを抑えられる。さらに、スパウト部２の雄ネジ２２ａと、プラグキャップ７の雌ネジ７ａとを締め込む構成であるため、強い力をかけなくてもプラグ５の先端部５１で内栓３に開口部３４ａを形成できる。 According to this embodiment, there is no need to provide the spout portion 2 with a check valve. Therefore, the opening of the spout portion 2 becomes larger, making it easier to fill with chemicals. Further, a special check valve is not required, and general-purpose pouch body 1 and spout portion 2 can be used, so costs can be reduced. Furthermore, since the male screw 22a of the spout part 2 and the female screw 7a of the plug cap 7 are tightened, the opening 34a is formed in the inner plug 3 with the tip 51 of the plug 5 without applying strong force. can.
