Description

流体吐出容器Fluid discharge container
　本発明は、流体を収容する収容袋を格納し、該収容袋内の流体を外部に吐出するための流体吐出容器に関するものである。 The present invention relates to a fluid discharge container for storing a storage bag containing fluid and for discharging the fluid in the storage bag to the outside.
　従来より、パーマ液、シャンプー、リンス、ボディーソープ、消毒液、調味料等の種々の流体を容器内部に収容し、容器外部に流体を吐出する流体吐出容器が広く用いられている。一般に、この流体吐出容器は、流体を容器内部に直接収容し、容器上部に設けられた手押し式ポンプやトリガー式ポンプ等の吐出機構により容器の内部の流体を吸入して、容器外部に流体を吐出するものである。 　Conventionally, fluid discharge containers have been widely used that contain various fluids such as perm liquids, shampoos, rinses, body soaps, disinfectants, and seasonings inside containers and discharge the fluids to the outside of the containers. In general, the fluid discharge container stores the fluid directly inside the container, sucks the fluid inside the container by means of a discharge mechanism such as a hand-pump or trigger pump provided on the upper part of the container, and discharges the fluid to the outside of the container. It is to be discharged.
　このような流体吐出容器は、使用によって容器内部の流体がなくなると容器ごと廃棄されていたが、エコロジー（自然環境保護）の観点から、容器内部の流体がなくなった場合、詰め替え用の袋に収容された同じ流体を流体吐出容器の内部に移し替えることが行われている。ところが、このように流体を袋から容器に移し替えるものだと、流体が袋や容器の外部の空気に触れるため、流体の品質を劣化させる虞があった。 In the past, when the fluid inside the container ran out due to use, the fluid discharge container was discarded together with the container. It has been practiced to transfer the same fluid that has been dispensed into the interior of a fluid ejection container. However, when the fluid is transferred from the bag to the container in this manner, the quality of the fluid may be degraded because the fluid comes into contact with the air outside the bag or container.
　そこで、最近では、容器内部に流体を直接収容するのではなく、流体が収容された収容袋を容器内部に格納し、該収容袋内の流体を外部に吐出する流体吐出容器が注目されている。例えば、本出願人は、貫通孔が設けられたコネクタを上部に有する収容袋と、開口部が形成され、該開口部から収容袋が格納される下側容器と、下側容器に脱着可能に設けられる上側容器と、上側容器に設けられ、収容袋の前記コネクタの貫通孔に挿入される雄部材を有する吐出機構とを備える流体吐出容器を提案している（特許文献１参照）。 Therefore, in recent years, attention has been paid to a fluid discharge container in which a storage bag containing a fluid is stored inside the container and the fluid in the storage bag is discharged to the outside, instead of directly containing the fluid inside the container. . For example, the present applicant has proposed a storage bag having a connector provided with a through hole in the upper part, a lower container having an opening formed therein and storing the storage bag from the opening, and a lower container detachably attachable to the lower container. and a discharge mechanism provided in the upper container and having a male member inserted into the through hole of the connector of the storage bag (see Patent Document 1).
　そして、この流体吐出容器のコネクタは、軸線方向の上側に設けられた上側コネクタ板と、軸線方向の下側に設けられた下側コネクタ板とを備え、上側コネクタ板の最大外径が前記下側容器の開口部の内径よりも小さくなるように形成されるとともに、下側コネクタ板の最大外径が前記下側容器の開口部の内径よりも大きくなるように形成され、下側コネクタ板の周縁部の上面が前記上側容器の段部に当接し、かつ下側コネクタ板の周縁部の下面が下側容器の周壁部に当接することによって、上側容器と下側容器に挟着される態様で固定される。 The connector of this fluid discharge container includes an upper connector plate provided on the upper side in the axial direction and a lower connector plate provided on the lower side in the axial direction. The lower connector plate is formed so as to be smaller than the inner diameter of the opening of the side container, and the maximum outer diameter of the lower connector plate is formed to be larger than the inner diameter of the opening of the lower container. The upper surface of the peripheral portion contacts the stepped portion of the upper container, and the lower surface of the peripheral portion of the lower connector plate contacts the peripheral wall portion of the lower container, thereby sandwiching between the upper container and the lower container. is fixed with .

　前記収容袋１は、図４に示すように、一般にスタンディングパウチと呼ばれる合成樹脂素材からなる可撓性の袋体１１と、合成樹脂素材からなる剛性のコネクタ１２とから構成される。 As shown in FIG. 4, the housing bag 1 is composed of a flexible bag body 11 made of synthetic resin material, generally called a standing pouch, and a rigid connector 12 made of synthetic resin material.
　前記袋体１１は、一方側に配置される正面視矩形状の第１のシート材１１１と、他方側に配置される第１のシート材１１１と同大同形の第２のシート材１１２と、下側に配置される第３のシート材１１３とを備え、第１のシート材１１１と第２のシート材１１２の上端部同士（コネクタ１２が配置される部分を除く）と側端部同士がヒートシールにより溶着されるともに、第１のシート材１１１および第２のシート材１１２の下端部と第３のシート部材１１３の周縁部がヒートシールにより溶着されることにより、全体として内部に流体が収容可能な空間が形成される。なお、袋体１１は、このようなスタンディングパウチに限定されるものではなく、２枚のシート材からなる平パウチや、４枚のシート材からなるガゼット袋など、その他の構成の袋体であってもよい。 The bag body 11 includes a first sheet member 111 having a rectangular shape in a front view and arranged on one side, and a second sheet member 112 having the same size and shape as the first sheet member 111 arranged on the other side, and a third sheet member 113 arranged on the lower side, and the upper ends of the first sheet member 111 and the second sheet member 112 (excluding the portion where the connector 12 is arranged) and the side ends are separated from each other. In addition to heat sealing, the lower end portions of the first sheet member 111 and the second sheet member 112 and the peripheral edge portion of the third sheet member 113 are welded by heat sealing, so that the fluid is kept inside as a whole. An accommodating space is formed. The bag body 11 is not limited to such a standing pouch, and may be a flat pouch made of two sheet materials, a gusset bag made of four sheet materials, or other bag body. may
　なお、袋体１１の高さＨ１は、下側容器２の内部の深さＨ２と同一あるいは深さＨ２より小さくなるように形成されている。また、袋体１１の幅は、袋体１１に流体を収納したときに袋体１１が下側容器２に格納可能な大きさに形成されている。 The height H1 of the bag body 11 is formed so as to be equal to or smaller than the depth H2 inside the lower container 2 . Moreover, the width of the bag body 11 is formed so that the bag body 11 can be stored in the lower container 2 when the bag body 11 contains the fluid.
　前記コネクタ１２は、図２～図４に示すように、本体部１２１と、本体部１２１の軸線方向の上側に設けられた上側コネクタ板１２２と、本体部１２１の軸線方向の下側に設けられた下側コネクタ板１２３と、本体部１２１を軸線方向に貫通する態様で設けられた貫通孔１２４と、貫通孔１２４の下端部に設けられた蓋部材１２５とを備え、本体部１２１の下部側面が第１のシート材１１１と第２のシート材１１２の間でヒートシールにより挟着されることにより、貫通孔１２４と袋体１１の軸線方向が一致する態様で袋体１１の上端部中央に設けられている。 2 to 4, the connector 12 includes a main body portion 121, an upper connector plate 122 provided on the upper side of the main body portion 121 in the axial direction, and a lower connector plate 122 provided on the lower side of the main body portion 121 in the axial direction. a lower connector plate 123, a through hole 124 provided so as to pass through the main body 121 in the axial direction, and a cover member 125 provided at the lower end of the through hole 124; is sandwiched between the first sheet material 111 and the second sheet material 112 by heat sealing, and the through hole 124 and the axial direction of the bag body 11 are aligned with each other in the upper end center of the bag body 11. is provided.
　前記上側コネクタ板１２２は、最大外径Ｒ２が上側容器３の上部（後述の段部３６）の内径Ｒ５とほぼ同一に形成されている。また、前記下側コネクタ板１２３は、最大外径Ｒ１が上側容器３の下部の内径Ｒ４（上側容器３の上部の内径Ｒ５より大きい）と同一またはＲ４よりやや小さくなるように形成されている。これにより、図３に示すように、収容袋１を下側容器２に格納した状態で上側容器３を下側容器２に完全に装着した際、コネクタ１２の全体が上側容器３の内部空間３３に収まる。 The upper connector plate 122 is formed such that the maximum outer diameter R2 is substantially the same as the inner diameter R5 of the upper portion of the upper container 3 (a step portion 36 described later). The lower connector plate 123 is formed such that the maximum outer diameter R1 is equal to or slightly smaller than the inner diameter R4 of the lower portion of the upper container 3 (larger than the inner diameter R5 of the upper portion of the upper container 3). As a result, as shown in FIG. 3 , when the upper container 3 is completely attached to the lower container 2 with the storage bag 1 stored in the lower container 2 , the entire connector 12 is in the inner space 33 of the upper container 3 . fits in.
　また、前記上側コネクタ板１２２は、最大外径Ｒ２が下側コネクタ板１２３の最大外径Ｒ１よりも小さく形成されている。これにより、上側コネクタ板１２２の周縁部１２２ａと下側コネクタ板１２３の周縁部１２３ａの間にクリアランス（空間）が生じるため、収容袋１を下側容器２に格納した状態で上側容器３を下側容器２に完全に装着した際、当該クリアランス（空間）に後述の上側容器３の段部３６が配置される。 Further, the upper connector plate 122 is formed such that the maximum outer diameter R2 is smaller than the maximum outer diameter R1 of the lower connector plate 123. As a result, a clearance (space) is generated between the peripheral edge portion 122a of the upper connector plate 122 and the peripheral edge portion 123a of the lower connector plate 123, so that the upper container 3 can be lowered while the storage bag 1 is stored in the lower container 2. When completely attached to the side container 2, a stepped portion 36 of the upper container 3, which will be described later, is arranged in the clearance (space).
　また、前記下側コネクタ板１２３は、最大外径Ｒ１が下側容器２の開口部２３の内径Ｒ３よりも大きくなるように形成されている。これにより、図３に示すように、収容袋１を下側容器２に格納した際、下側コネクタ板１２３の周縁部１２３ａの下面と下側容器２の上端部２２ａの端面とが当接するため、収容袋１のコネクタ１２が下側容器２の開口部２３において下側容器３に係止されて、収容袋１の袋体１１が下側容器２の内部で吊り下げられた状態となる。 Also, the lower connector plate 123 is formed so that the maximum outer diameter R1 is larger than the inner diameter R3 of the opening 23 of the lower container 2 . As a result, as shown in FIG. 3, when the storage bag 1 is stored in the lower container 2, the lower surface of the peripheral edge portion 123a of the lower connector plate 123 and the end surface of the upper end portion 22a of the lower container 2 come into contact with each other. , the connector 12 of the containing bag 1 is locked to the lower container 3 at the opening 23 of the lower container 2 , and the bag body 11 of the containing bag 1 is suspended inside the lower container 2 .
　また、前記上側コネクタ板１２２は、図７（ａ）に示すように、径方向内側に窪んだ２個の凹部１２２ｂが互いに対向する態様で形成されている。また、前記コネクタ１２の下側コネクタ板１２３も、前記コネクタ１２の上側コネクタ板１２２と同様、平面方向に延びる態様の平板状に形成されており、径方向内側に窪んだ２個の凹部１２３ｂが互いに対向する態様で形成されている。これら上側コネクタ板１２２の凹部１２２ｂと下側コネクタ板１２３の凹部１２３ｂは、軸線方向に沿って面一となるように形成されており、作業者の手の指（例えば、人差し指と親指）を凹部１２２ｂ，１２３ｂを沿わせることによりコネクタ１２を摘み易くなっている。 In addition, as shown in FIG. 7(a), the upper connector plate 122 is formed so that two recesses 122b that are recessed inward in the radial direction face each other. Similarly to the upper connector plate 122 of the connector 12, the lower connector plate 123 of the connector 12 is also formed in the shape of a flat plate extending in the plane direction, and has two concave portions 123b that are recessed inward in the radial direction. They are formed in a manner facing each other. The recessed portion 122b of the upper connector plate 122 and the recessed portion 123b of the lower connector plate 123 are formed so as to be flush with each other along the axial direction, and the fingers of the operator's hand (for example, the index finger and thumb) are recessed. 122b and 123b are aligned so that the connector 12 can be easily picked up.
　また、前記上側コネクタ板１２２と前記下側コネクタ板１２３は、コネクタ１２の軸線方向に所定距離を隔てながら対向する態様で設けられている。これにより、製造時において収容袋１に流体を充填する際、収容袋１のコネクタ１２の上側コネクタ板１２２と下側コネクタ板１２３の間に別に設けられた係止部材を係止させることにより、流体を安定して充填することができる。 In addition, the upper connector plate 122 and the lower connector plate 123 are provided facing each other with a predetermined distance in the axial direction of the connector 12 . As a result, when the storage bag 1 is filled with fluid during manufacture, by locking the locking member separately provided between the upper connector plate 122 and the lower connector plate 123 of the connector 12 of the storage bag 1, Fluid can be stably filled.
　前記下側容器２は、図５に示すように、円形状の底壁部２１と、底壁部２１の周縁から立設された円筒状の周壁部２２とからなる合成樹脂製の剛性の容器であって、周壁部２２の上部に開口部２３が形成されるとともに、周壁部２２の上部の外周面に雄螺子部２４が形成されている。この雄螺子部２４は、後述するように上側容器３の雌螺子部３４と螺合する。 As shown in FIG. 5, the lower container 2 is a rigid synthetic resin container comprising a circular bottom wall portion 21 and a cylindrical peripheral wall portion 22 erected from the peripheral edge of the bottom wall portion 21. An opening 23 is formed in the upper portion of the peripheral wall portion 22 , and a male screw portion 24 is formed on the outer peripheral surface of the upper portion of the peripheral wall portion 22 . The male threaded portion 24 is screwed with the female threaded portion 34 of the upper container 3 as will be described later.
　前記上側容器３は、図６に示すように、円形状の天壁部３１と、天壁部３１の周縁から垂下した円筒状の周壁部３２とからなる合成樹脂製の剛性の容器であって、収容袋１のコネクタ１２を被覆する内部空間３３が形成されている。 As shown in FIG. 6, the upper container 3 is a rigid synthetic resin container comprising a circular top wall portion 31 and a cylindrical peripheral wall portion 32 hanging down from the peripheral edge of the top wall portion 31. , an internal space 33 covering the connector 12 of the housing bag 1 is formed.
　また、前記上側容器３は、周壁部３２の下部の内周面に雌螺子部３４が形成されており、下側容器２に形成された雄螺子部２４と螺合することにより下側容器２に装着される。 In addition, the upper container 3 has a female screw portion 34 formed on the inner peripheral surface of the lower portion of the peripheral wall portion 32 . is attached to the
　また、前記上側容器３は、天壁部３１の中央部に貫通孔３５が形成されており、吐出機構４が上側容器３に取り付けられた際、吐出機構４の雄部材４１が貫通孔３５を貫通する。 Further, the upper container 3 has a through hole 35 formed in the central portion of the ceiling wall portion 31 , and when the discharge mechanism 4 is attached to the upper container 3 , the male member 41 of the discharge mechanism 4 passes through the through hole 35 . Penetrate.
　また、前記上側容器３は、周壁部３２の上部において、軸方向の断面がＬ字状の段部３６が周方向に沿って形成されている。 In addition, in the upper portion of the peripheral wall portion 32 of the upper container 3, a stepped portion 36 having an L-shaped cross section in the axial direction is formed along the peripheral direction.
　前記段部３６は、収容袋１が下側容器２に格納された状態で上側容器３が下側容器２に完全に装着された際、収容袋１のコネクタ１２の下側コネクタ板１２３の周縁部１２３ａの径方向内側であって、かつ上側コネクタ板１２２の周縁部１２２ａの径方向外側の位置するような幅に形成されている。 When the upper container 3 is completely attached to the lower container 2 with the container bag 1 stored in the lower container 2 , the stepped portion 36 is formed along the periphery of the lower connector plate 123 of the connector 12 of the container bag 1 . It is formed to have a width that is located radially inside the portion 123 a and radially outside the peripheral edge portion 122 a of the upper connector plate 122 .
　また、前記段部３６は、収容袋１が下側容器２に格納された状態で上側容器３が下側容器２に完全に装着された際、下側コネクタ板１２３の周縁部１２３ａの上面に当接するとともに、上側コネクタ板１２２の上面と上側容器３の天壁部３１の下面との間において僅かな隙間が出来るような軸方向の高さに形成されている。 Further, when the upper container 3 is completely attached to the lower container 2 with the storage bag 1 stored in the lower container 2, the stepped portion 36 is formed on the upper surface of the peripheral edge portion 123a of the lower connector plate 123. The upper connector plate 122 and the lower surface of the top wall portion 31 of the upper container 3 are formed at an axial height so that a slight gap is formed between the upper surface of the upper connector plate 122 and the lower surface of the ceiling wall portion 31 of the upper container 3 .
　このため、図３に示すように、収容袋１を下側容器２に格納した状態で上側容器３を下側容器２に完全に装着した際、下側コネクタ板１２３の周縁部１２３ａの上面が上側容器３の段部３６の下面に当接し、かつ下側コネクタ板１２３の周縁部１２３ａの下面が下側容器２の周壁部２２の上端部２２ａに当接することにより、コネクタ１２が上側容器３と下側容器２に挟着されるため、収容袋１を流体吐出容器に安定して格納することができる。また、上側コネクタ板１２２の上面と上側容器３の天壁部３１の下面との間において僅かな隙間が出来るため、上側容器３を下側容器２に装着する際、上側容器３の雌螺子部３４と下側容器２の雄螺子部２４を最後まで確実に螺着することができる。 Therefore, as shown in FIG. 3, when the upper container 3 is completely attached to the lower container 2 with the storage bag 1 stored in the lower container 2, the upper surface of the peripheral edge portion 123a of the lower connector plate 123 is The connector 12 contacts the lower surface of the stepped portion 36 of the upper container 3 and the lower surface of the peripheral edge portion 123a of the lower connector plate 123 contacts the upper end portion 22a of the peripheral wall portion 22 of the lower container 2. and the lower container 2, the storage bag 1 can be stably stored in the fluid discharge container. In addition, since a slight gap is formed between the upper surface of the upper connector plate 122 and the lower surface of the ceiling wall portion 31 of the upper container 3 , when the upper container 3 is attached to the lower container 2 , the female screw portion of the upper container 3 is 34 and the male screw portion 24 of the lower container 2 can be securely screwed to the end.
　また、前記段部３６は、内周面に第２の雌螺子部３６ａが形成されており、コネクタ１２の上側コネクタ板１２２の周縁部１２２ａと螺合するものとなされている。具体的には、収容袋１を下側容器２に格納した状態で上側容器３を下側容器２に装着する際、上側容器３の雌螺子部３４と下側容器２の雄螺子部２４を螺合させていくと、それに伴ってコネクタ１２の上側コネクタ板１２２の周縁部１２２ａが上側容器３の段部３６の第２の雌螺子部３６ａに螺合していき、上側コネクタ板１２２が上側容器３の内側に固定される。このため、使用途中で上側容器３を誤って開けた場合でも、収容袋１が上側容器３から外れることを防止し、収容袋１の内部のエアレスの状態を維持することが可能となる。 Further, the stepped portion 36 has a second female screw portion 36a formed on the inner peripheral surface thereof, and is screwed with the peripheral portion 122a of the upper connector plate 122 of the connector 12.

As the screws are screwed together, the peripheral edge portion 122a of the upper connector plate 122 of the connector 12 is screwed into the second female screw portion 36a of the stepped portion 36 of the upper container 3, and the upper connector plate 122 is screwed to the upper side. It is fixed inside the container 3 . Therefore, even if the upper container 3 is accidentally opened during use, the containing bag 1 is prevented from coming off from the upper container 3, and the airless state inside the containing bag 1 can be maintained.
　なお、本実施形態のように上側容器３の周壁部３２の外側を窪ませるように段部３６を形成した場合、吐出機構４を覆うためのキャップ部材５を上側容器３の段部３６の外側部分に嵌合させることができる。　 When the stepped portion 36 is formed so as to recess the outer side of the peripheral wall portion 32 of the upper container 3 as in the present embodiment, the cap member 5 for covering the discharge mechanism 4 is positioned outside the stepped portion 36 of the upper container 3 . part can be fitted.　
　前記吐出機構４は、図６に示すように、いわゆるプッシュ式ポンプが採用されており、上側容器３の天壁部３１の上面に設けられている。この吐出機構４は、下端部に流体を吸引する吸引口４４を有する管状の雄部材４１と、上端部に流体を吐出する吐出口４５を有するポンプ部４２と、内部を貫通する態様で吸引口４４と吐出口４５と連通する流体通路４３とを有する。 As shown in FIG. 6, the discharge mechanism 4 employs a so-called push-type pump, which is provided on the upper surface of the top wall portion 31 of the upper container 3. The discharge mechanism 4 includes a tubular male member 41 having a suction port 44 for sucking fluid at its lower end, a pump portion 42 having a discharge port 45 for discharging fluid at its upper end, and a suction port penetrating through the inside. 44 and a fluid passage 43 communicating with the outlet 45 .
　また、前記吐出機構４は、図３に示すように、上側容器３が下側容器２に装着した際、雄部材４１が収容袋１のコネクタ１２の貫通孔に密着状態に挿入され、収容袋１のコネクタ１２の貫通孔１２４の下端部に設けられた蓋部材１２５を押し出すことにより、収容袋１の内部に臨んだ状態となる。これにより、ポンプ部４２を作業者の手で一回ないし複数回押し下げると、ポンプの吸引作用により収容袋１に収容されている流体を雄部材４１の吸引口４４から吸引して、流体通路４３を通じて吐出口４５から容器外部に吐出することができる。 3, when the upper container 3 is attached to the lower container 2, the male member 41 is inserted into the through hole of the connector 12 of the container bag 1 in close contact with the container bag. By pushing out the lid member 125 provided at the lower end of the through hole 124 of the connector 12 of the connector 12, the inside of the housing bag 1 is exposed. As a result, when the pump portion 42 is pushed down once or several times by the operator's hand, the fluid contained in the housing bag 1 is sucked from the suction port 44 of the male member 41 by the suction action of the pump, and the fluid passage 43 is opened. It can be discharged to the outside of the container from the discharge port 45 through.
