Description
本発明は、溶液中に液体若しくは固体の粒子が分散した分散液を作ることのできる攪拌用容器に関する。 The present invention relates to a stirring vessel capable of producing a dispersion in which liquid or solid particles are dispersed in a solution.
分離液状ドレッシングの内容物は少なくとも油成分を含む油相部と酢などの水溶成分を含む水相部とが混合されており、包装容器内で油相部と水相部とが分離している。容器を振らずにそのまま使用すると上層の油相部だけが取り出されるため、予め包装容器をよく振って油相部と水相部とを混合して分散液として野菜等に振りかけていた。 The content of the separated liquid dressing is a mixture of an oil phase part containing at least an oil component and an aqueous phase part containing a water-soluble component such as vinegar, and the oil phase part and the aqueous phase part are separated in the packaging container. . When the container is used as it is without being shaken, only the upper oil phase part is taken out. Therefore, the oil container part and the aqueous phase part are mixed well in advance and sprinkled on vegetables or the like as a dispersion.
しかしながら、水相部と油相部とは混合しにくいため、分散液を形成するためには力強く振る必要がある。このため、女性、子供、高齢者等の力の弱い使用者の場合は扱いにくい問題があった。即ち、振り方が不十分な場合には上層の油相部だけが流出し、野菜等に振りかけられた分離液状ドレッシングが油っぽくなる。その結果、酢によってもたらされる酸味や香辛料が与える味が生かされなくなってしまう場合が生ずる。 However, since the water phase part and the oil phase part are difficult to mix, it is necessary to vigorously shake to form a dispersion. For this reason, in the case of a weak user such as a woman, a child, or an elderly person, there is a problem that it is difficult to handle. That is, when the way of shaking is insufficient, only the upper oil phase part flows out, and the separated liquid dressing sprinkled on vegetables or the like becomes oily. As a result, there are cases where the sourness and spices provided by vinegar cannot be utilized.
また、分離液状ドレッシングの内容物を分散した後に包装容器の蓋を開放するのに手間取ると、油相部と水相部とが分離し始める。これにより、上記と同様に上層の油相部だけが流出する問題がある。 Moreover, if it takes time to open the lid of the packaging container after the contents of the separated liquid dressing are dispersed, the oil phase part and the water phase part start to separate. As a result, there is a problem that only the upper oil phase portion flows out as described above.
上記問題を解決するために、分離液状ドレッシングの内容物に乳化剤や安定剤等の添加剤を添加することが知られている。これにより、振る力や回数が少なくても分散液を生成して安定させることができる。しかし、分離液状ドレッシングの内容物に乳化剤を添加すると乳化してエマルション（乳濁液）が生成される。このため、乳化液状ドレッシングと区別される分離液状ドレッシング特有の風味が失われる。 In order to solve the above problems, it is known to add additives such as emulsifiers and stabilizers to the contents of the separated liquid dressing. Thereby, even if there is little shaking force and frequency | count, a dispersion liquid can be produced | generated and can be stabilized. However, when an emulsifier is added to the contents of the separated liquid dressing, it is emulsified to produce an emulsion (emulsion). For this reason, the flavor peculiar to the separation liquid dressing which is distinguished from the emulsified liquid dressing is lost.
また、乳化剤や安定剤等の添加剤は化学薬品をベースとして生成される。これにより、美味しさが損なわれる場合や、昨今の健康ブームの趨勢においては健康安全面で消費者に避けられる場合が多くなる。 Additives such as emulsifiers and stabilizers are produced based on chemicals. As a result, there are many cases where the taste is impaired, and consumers are avoided in terms of health and safety in the current trend of health boom.
一方、内部の液体に大きなせん断力を与えて分散液を生成する攪拌用容器を分離液状ドレッシングの包装容器として用いることが特許文献１に開示されている。この攪拌用容器は上端を開口した有底筒状の本体部を有し、本体部の上部の内周面に放射状の突起部が設けられる。本体部内は突起部の下方の第１チャンバと上方の第２チャンバとに仕切られる。 On the other hand, Patent Document 1 discloses that a stirring container that generates a dispersion by applying a large shearing force to an internal liquid is used as a packaging container for a separate liquid dressing. This stirring container has a bottomed cylindrical main body having an open upper end, and radial protrusions are provided on the inner peripheral surface of the upper portion of the main body. The inside of the main body is partitioned into a first chamber below the protrusion and a second chamber above.
分離液状ドレッシングの内容物は本体部内に入れられ、本体部を振ると第１チャンバ内の内容物が突起部に衝突する。分離液状ドレッシングの内容物は突起部との衝突によって大きなせん断力が与えられて第２チャンバに移動し、第２チャンバ内の空気が含まれる。これにより、エマルションに近い状態の分散液が生成され、第２チャンバ内の空気を含むことによって分散した状態を持続させることができる。 The contents of the separated liquid dressing are put in the main body, and when the main body is shaken, the contents in the first chamber collide with the protrusions. The contents of the separated liquid dressing are subjected to a large shearing force due to collision with the protrusions and move to the second chamber, and air in the second chamber is included. Thereby, the dispersion liquid of the state close | similar to an emulsion is produced | generated, and the dispersed state can be maintained by including the air in a 2nd chamber.
また、特許文献２には他の攪拌用容器が開示されている。この攪拌用容器は容器内に捩れ方向の異なる２つの捩れ翼が上下に連結され、連結側の端面が交差している。分離液状ドレッシング等の被処理物は捩れ翼によって旋回して攪拌作用が増加するとともに、上下段に跨って流動する際に捩れ翼の端縁に衝突してせん断作用を受ける。これにより、少ない振動回数で分散液を生成することができる。 Patent Document 2 discloses another stirring container. In this stirring container, two twisted wings having different twisting directions are connected vertically in the container, and end faces on the connection side intersect. An object to be treated such as a separated liquid dressing is swirled by a twisted blade to increase the stirring action, and when flowing across the upper and lower stages, it collides with the edge of the twisted blade and receives a shearing action. Thereby, a dispersion liquid can be generated with a small number of vibrations.
しかしながら、上記特許文献１に開示された攪拌用容器によると、空気を入れておく第２チャンバを必要とするため内容量が小さくなる問題があった。また、特許文献２に開示された攪拌用容器によると、攪拌用容器は主に軸方向（長手方向）に振られるため液体が捩り翼の表面に斜め方向に衝突する。このため、被処理物が捩り翼に衝突した際の衝撃力が弱く、いぜんとして振る力や回数を多く必要とする問題があった。 However, according to the stirring container disclosed in the above-mentioned Patent Document 1, there is a problem that the internal volume becomes small because the second chamber for storing air is required. Further, according to the stirring container disclosed in Patent Document 2, the stirring container is shaken mainly in the axial direction (longitudinal direction), so that the liquid collides with the surface of the twisted blade in an oblique direction. For this reason, there is a problem that the impact force when the object to be processed collides with the torsional blade is weak, and the force and the number of times of shaking are still necessary.
また、攪拌用容器を振ることにより、液体中に固体粒子を分散させた分散液（懸濁液）を生成することもでき、中に入れた液体から固体を分離させることもできる。これらの場合も上記と同様に、攪拌用容器を振る力や回数を多く必要とする問題があった。また、分離液状ドレッシングと同様に、攪拌して用いられる分離液状の化粧品や医薬品についても同様の問題がある。 Further, by shaking the stirring vessel, a dispersion liquid (suspension) in which solid particles are dispersed in the liquid can be generated, and the solid can be separated from the liquid put in the liquid. In these cases, as described above, there is a problem that a large force and number of times of shaking the stirring container are required. In addition, similar to the separated liquid dressing, the separated liquid cosmetics and pharmaceuticals used by stirring have the same problem.
本発明は、内容量を小さくせずに振る力や回数を少なくして液体に大きな攪拌力を与えて分散や分離を行うことのできる攪拌用容器を提供することを目的とする。また、この攪拌用容器に入れられた分離液状ドレッシング、分離液状化粧品及び医薬品を提供することを目的とする。 An object of the present invention is to provide a stirring container capable of dispersing and separating by giving a large stirring force to a liquid by reducing the shaking force and frequency without reducing the internal volume. It is another object of the present invention to provide a separate liquid dressing, a separate liquid cosmetic and a pharmaceutical product placed in the stirring container.
上記目的を達成するために本発明は、液体を入れて振ることにより、攪拌された液体の分散や分離を行う攪拌用容器において、上部に開口部を有する有底筒状の外筒と、前記開口部を塞ぐ着脱自在の蓋体と、前記外筒内に配される筒状の内筒とを備え、軸方向に所定周期で並設される溝部を前記内筒の内周面及び外周面の一方または両方に設け、前記溝部の軸方向の断面形状を矩形状にしたことを特徴としている。 In order to achieve the above object, the present invention provides a stirring vessel for dispersing and separating a stirred liquid by adding and shaking the liquid, and a bottomed cylindrical outer cylinder having an opening in the upper part, A detachable lid for closing the opening and a cylindrical inner cylinder arranged in the outer cylinder, and grooves arranged in a predetermined cycle in the axial direction are provided on the inner and outer peripheral surfaces of the inner cylinder. It is characterized in that it is provided in one or both of them, and the cross-sectional shape in the axial direction of the groove is rectangular.
この構成によると、例えば、油相部を形成する液体と水相部を形成する液体とが攪拌用容器の外筒内に入れられ、蓋体で開口部が塞がれる。攪拌用容器を振ると内部の液体は内筒及び外筒に沿って上下に揺動する。内筒の内周面または外周面には螺旋状や環状に形成された溝部が軸方向に並設される。内筒に沿って流通する液体の一部は溝部内に流入し、溝部内に渦が形成される。攪拌用容器を軸方向に振ることにより回転方向が逆方向の渦が溝部内に形成されるため、直前の渦が破壊されて液体に大きなせん断力が働く。これにより、水相部と油相部の液体が分散してエマルションに近い状態の分散液が作成される。液体と粉体とを外筒内に入れて分散液（懸濁液）を作成する場合も同様である。 According to this configuration, for example, the liquid forming the oil phase portion and the liquid forming the water phase portion are placed in the outer cylinder of the stirring vessel, and the opening is closed by the lid. When the stirring container is shaken, the liquid inside swings up and down along the inner cylinder and the outer cylinder. Grooves formed in a spiral shape or an annular shape are arranged in parallel in the axial direction on the inner peripheral surface or outer peripheral surface of the inner cylinder. Part of the liquid flowing along the inner cylinder flows into the groove, and a vortex is formed in the groove. As the stirring vessel is shaken in the axial direction, a vortex having a reverse rotation direction is formed in the groove, so that the immediately preceding vortex is destroyed and a large shear force acts on the liquid. Thereby, the liquid of the state which was disperse | distributing the liquid of a water phase part and an oil phase part, and was close to an emulsion is created. The same applies to a case where a liquid (powder) is placed in an outer cylinder to form a dispersion (suspension).
また本発明は、液体を入れて振ることにより、攪拌された液体の分散や分離を行う攪拌用容器において、一端を開口して外装を形成する筒状の外筒と、前記開口を塞ぐ蓋体とを備え、軸方向に所定周期で並設される溝部を前記外筒の内周面に設け、前記溝部の軸方向の断面形状を矩形状にするとともに、前記溝部の幅と深さとを略同じにしたことを特徴としている。 Further, the present invention provides a stirring container that disperses and separates a stirred liquid by adding and shaking the liquid, and a cylindrical outer cylinder that opens at one end to form an exterior, and a lid that closes the opening A groove portion arranged in parallel in the axial direction at a predetermined period is provided on the inner peripheral surface of the outer cylinder, the axial cross-sectional shape of the groove portion is rectangular, and the width and depth of the groove portion are approximately It is characterized by the same thing.
この構成によると、例えば、油相部を形成する液体と水相部を形成する液体とが攪拌用容器の外筒内に入れられ、蓋体で開口部が塞がれる。攪拌用容器を振ると内部の液体は外筒に沿って上下に揺動する。この時、外筒に沿って流通する液体の一部は溝部内に流入し、溝部内に渦が形成される。外筒を上下に振ることにより回転方向が逆方向の渦が溝部内に形成されるため、直前の渦が破壊されて液体に大きなせん断力が働く。これにより、水相部と油相部の液体が分散してエマルションに近い状態の分散液が作成される。 According to this configuration, for example, the liquid forming the oil phase portion and the liquid forming the water phase portion are placed in the outer cylinder of the stirring vessel, and the opening is closed by the lid. When the agitation container is shaken, the liquid in the inside swings up and down along the outer cylinder. At this time, a part of the liquid flowing along the outer cylinder flows into the groove, and a vortex is formed in the groove. By swinging the outer cylinder up and down, a vortex having a reverse rotation direction is formed in the groove, so that the immediately preceding vortex is destroyed and a large shear force acts on the liquid. Thereby, the liquid of the state which was disperse | distributing the liquid of a water phase part and an oil phase part, and was close to an emulsion is created.
また本発明は、上記構成の攪拌用容器において、前記溝部の側壁を軸方向に対して垂直に形成したことを特徴としている。 According to the present invention, in the stirring container having the above-described configuration, the side wall of the groove is formed perpendicular to the axial direction.
また本発明は、上記構成の攪拌用容器において、前記溝部の側壁は開放側の端部の曲率半径が１ｍｍ以下に形成されることを特徴としている。 According to the present invention, in the stirring container having the above-described configuration, the side wall of the groove is formed so that the radius of curvature of the open end is 1 mm or less.
本発明によると、内筒もしくは外筒に軸方向に所定周期で並設される溝部を設けたので、攪拌用容器を軸方向に振ることによって回転方向が逆方向の渦が溝部内に形成され、直前の渦が破壊されて液体に大きなせん断力が働く。従って、振る力や回数を少なくしても、分離液状ドレッシング等の液体を充分分散させることや牛乳等の液体を充分分離させることができる。 According to the present invention, the inner cylinder or the outer cylinder is provided with the groove portion arranged in parallel in the axial direction with a predetermined period, so that the vortex having the reverse rotation direction is formed in the groove portion by shaking the stirring vessel in the axial direction. The previous vortex is destroyed and a large shearing force is applied to the liquid. Therefore, even if the shaking force and the number of times are reduced, it is possible to sufficiently disperse a liquid such as a separation liquid dressing or to sufficiently separate a liquid such as milk.
以下に本発明の実施形態を図面を参照して説明する。図１は第１実施形態の攪拌用容器の正面断面図を示している。攪拌用容器１は分離液状ドレッシング１０（図３参照）の包装容器になっている。攪拌用容器１は上面に開口部２ａが形成される有底筒状の外筒２を有している。外筒２はガラスやポリエチレンテレフタラート（ＰＥＴ）等の透明材料により形成され、内部を視認可能になっている。開口部２ａは外筒２に螺合される着脱自在の蓋体６によって塞がれる。蓋体６はポリプロピレン等の樹脂成形品から成っている。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a front sectional view of the stirring container of the first embodiment. The stirring container 1 is a packaging container for the separated liquid dressing 10 (see FIG. 3). The stirring container 1 has a bottomed cylindrical outer cylinder 2 having an opening 2a formed on the upper surface. The outer cylinder 2 is made of a transparent material such as glass or polyethylene terephthalate (PET), so that the inside can be visually confirmed. The opening 2 a is closed by a detachable lid 6 that is screwed into the outer cylinder 2. The lid 6 is made of a resin molded product such as polypropylene.
外筒２内には筒状の内筒３が配されている。図２は内筒３の斜視図を示している。内筒３はポリエチレンテレフタラート（ＰＥＴ）等の透明樹脂により形成され、内部を視認可能になっている。内筒３の外周面３ａ及び内周面３ｂには複数の環状の溝部４ａ、４ｂが内筒３の軸方向に周期的に並設されている。 A cylindrical inner cylinder 3 is disposed in the outer cylinder 2. FIG. 2 shows a perspective view of the inner cylinder 3. The inner cylinder 3 is formed of a transparent resin such as polyethylene terephthalate (PET), so that the inside can be visually confirmed. A plurality of annular grooves 4 a and 4 b are periodically arranged in the axial direction of the inner cylinder 3 on the outer peripheral surface 3 a and the inner peripheral surface 3 b of the inner cylinder 3.
溝部４ａ、４ｂは薄肉に形成される内筒３の周壁を屈曲して形成され、共通の側壁を有している。即ち、外周面３ａの溝部４ａ間の陸部５ａの裏面に内周面３ｂの溝部４ｂが形成され、内周面３ｂの溝部４ｂ間の陸部５ｂの裏面に外周面３ａの溝部４ａが形成される。これにより、容易に溝部４ａ、４ｂを形成することができる。尚、溝部４ａ、４ｂは幅Ｗが５ｍｍ、深さＤが５ｍｍ、周期Ｔが１０ｍｍで形成されている。 The groove portions 4a and 4b are formed by bending the peripheral wall of the inner cylinder 3 formed thin, and have a common side wall. That is, the groove portion 4b of the inner peripheral surface 3b is formed on the back surface of the land portion 5a between the groove portions 4a of the outer peripheral surface 3a, and the groove portion 4a of the outer peripheral surface 3a is formed on the back surface of the land portion 5b between the groove portions 4b of the inner peripheral surface 3b. Is done. Thereby, the groove parts 4a and 4b can be easily formed. The grooves 4a and 4b are formed with a width W of 5 mm, a depth D of 5 mm, and a period T of 10 mm.
内筒３は外筒２の底面に接して配され、内筒３の下端には切欠き３ｃが設けられる。切欠き３ｃによって攪拌用容器１の下部で内筒３の外側と内側とを連通させる連通部が構成されている。これにより、外筒２の内部の液体が内筒３の内外を容易に行き来する。内筒３に設けた貫通孔によって連通部を形成してもよい。また、外筒２の底面に対して内筒３を離して配置し、内筒３の下方に連通部を形成してもよい。 The inner cylinder 3 is disposed in contact with the bottom surface of the outer cylinder 2, and a notch 3 c is provided at the lower end of the inner cylinder 3. The notch 3c constitutes a communicating portion that communicates the outside and the inside of the inner cylinder 3 at the lower part of the stirring vessel 1. Thereby, the liquid inside the outer cylinder 2 easily moves back and forth inside the inner cylinder 3. The communicating portion may be formed by a through hole provided in the inner cylinder 3. Further, the inner cylinder 3 may be arranged away from the bottom surface of the outer cylinder 2, and a communication portion may be formed below the inner cylinder 3.
外筒２内には所定の内容物８（図３参照）が入れられ、攪拌用容器１を包装容器とする分離液状ドレッシング１０（図３参照）が得られる。分離液状ドレッシング１０の内容物８は酢を主成分とした液体から成る酸性の水相部と、オイルを主成分とした液体から成る油相部とを有している。水相部の液体は酢の他に酸味料、清水、食塩、糖類、スパイス類、果汁、しょうゆ等が目的とする製品の用途に合わせて適宜加えられる。油相部の液体はサラダ油等のオイルに加え、必要に応じて油溶性のスパイス類を溶解して用いられる。水相部と油相部との体積比は通常、１：９〜９：１になっている。 A predetermined content 8 (see FIG. 3) is placed in the outer cylinder 2 to obtain a separated liquid dressing 10 (see FIG. 3) using the stirring container 1 as a packaging container. The contents 8 of the separation liquid dressing 10 have an acidic aqueous phase portion made of a liquid mainly composed of vinegar and an oil phase portion made of a liquid mainly composed of oil. In addition to vinegar, the liquid in the aqueous phase is appropriately added according to the intended use of the product such as acidulant, fresh water, salt, sugar, spices, fruit juice, soy sauce and the like. The liquid in the oil phase part is used by dissolving oil-soluble spices, if necessary, in addition to oil such as salad oil. The volume ratio of the water phase part to the oil phase part is usually 1: 9 to 9: 1.
分離液状ドレッシング１０の内容物８は一定期間連続して放置状態が続くと水相部と油相部とが分離する。このため、使用する際には使用者によって攪拌用容器１を振ることにより内容物８を混合撹拌する。これにより、内容物８の二相を分散させて分散液にしてから食品等に振り掛けられる。 When the contents 8 of the separated liquid dressing 10 are left standing for a certain period of time, the water phase portion and the oil phase portion are separated. For this reason, when using, the content 8 is mixed and stirred by shaking the stirring container 1 by the user. As a result, the two phases of the contents 8 are dispersed into a dispersion and then sprinkled on the food.
図３、図４は分離液状ドレッシング１０を振った時の状態を説明する図である。分離液状ドレッシング１０を長手方向に振ると、上方に移動させる期間と下方に移動させる期間とが交互に繰り返される。分離液状ドレッシング１０が矢印Ａ１に示すように上方に移動すると内容物８は慣性力を受けて矢印Ｂ１に示すように下方に移動する。また、分離液状ドレッシング１０が矢印Ａ２に示すように下方に移動すると内容物８は矢印Ｂ２に示すように上方に移動する。 3 and 4 are views for explaining the state when the separated liquid dressing 10 is shaken. When the separated liquid dressing 10 is shaken in the longitudinal direction, the period of moving upward and the period of moving downward are alternately repeated. When the separated liquid dressing 10 moves upward as indicated by an arrow A1, the content 8 receives an inertial force and moves downward as indicated by an arrow B1. Further, when the separated liquid dressing 10 moves downward as indicated by an arrow A2, the content 8 moves upward as indicated by an arrow B2.
図５、図６はそれぞれ図３のＤ部詳細図及び図４のＥ部詳細図になっている。内容物８が矢印Ｂ１の方向に移動すると、図５に示すように内筒３の外周面３ａ及び内周面３ｂに沿って流通する液体は溝部４ａ、４ｂ内に流入する。これにより、溝部４ａ内には図中、反時計回りに回転する渦２１ａが形成され、溝部４ｂ内には図中、時計回りに回転する渦２１ｂが形成される。 5 and 6 are a detailed view of a D portion in FIG. 3 and a detailed view of a E portion in FIG. 4, respectively. When the contents 8 move in the direction of the arrow B1, as shown in FIG. 5, the liquid flowing along the outer peripheral surface 3a and the inner peripheral surface 3b of the inner cylinder 3 flows into the grooves 4a and 4b. Thus, a vortex 21a that rotates counterclockwise in the drawing is formed in the groove 4a, and a vortex 21b that rotates clockwise in the drawing is formed in the groove 4b.
その直後に内容物８が矢印Ｂ２の方向に移動すると、図６に示すように、溝部４ａ内には図中、時計回りの渦２２ａが形成される。また、溝部４ｂ内には図中、反時計回りの渦２２ｂが形成される。即ち、溝部４ａに流入する液体は直前に形成された渦２１ａを打ち消すように作用してこれを破壊して消滅させ、溝部４ａ内に逆方向に回転する渦２２ａが発達する。同様に、溝部４ｂに流入する液体は直前に形成された渦２１ｂを打ち消すように作用してこれを破壊して消滅させ、溝部４ｂ内に逆方向に回転する渦２２ｂが発達する。 Immediately thereafter, when the contents 8 move in the direction of arrow B2, as shown in FIG. 6, a clockwise vortex 22a in the figure is formed in the groove 4a. Further, a counterclockwise vortex 22b in the figure is formed in the groove 4b. That is, the liquid flowing into the groove 4a acts so as to cancel the vortex 21a formed immediately before, destroys it and disappears, and the vortex 22a rotating in the reverse direction develops in the groove 4a. Similarly, the liquid flowing into the groove 4b acts so as to cancel the vortex 21b formed immediately before, destroys it and disappears, and a vortex 22b rotating in the reverse direction develops in the groove 4b.
その直後に内容物８が矢印Ｂ１の方向に移動すると、上記と同様に溝部４ａ、４ｂ内に渦２１ａ、２１ｂが形成される。即ち、溝部４ａに流入する液体は直前に形成された渦２２ａを打ち消すように作用してこれを破壊して消滅させ、溝部４ａ内に逆方向に回転する渦２１ａが発達する。同様に、溝部４ｂに流入する液体は直前に形成された渦２２ｂを打ち消すように作用してこれを破壊して消滅させ、溝部４ｂ内に逆方向に回転する渦２１ｂが発達する。以降、これらの動作が繰り返される。 Immediately thereafter, when the contents 8 move in the direction of the arrow B1, vortices 21a and 21b are formed in the groove portions 4a and 4b in the same manner as described above. That is, the liquid flowing into the groove 4a acts so as to cancel the vortex 22a formed immediately before, destroys it and disappears, and the vortex 21a rotating in the reverse direction develops in the groove 4a. Similarly, the liquid flowing into the groove 4b acts so as to cancel the vortex 22b formed immediately before, destroys it and disappears, and the vortex 21b rotating in the reverse direction develops in the groove 4b. Thereafter, these operations are repeated.
渦２１ａ、２１ｂ、２２ａ、２２ｂが破壊されて消滅する際には液体に大きなせん断力が発生する。溝部４ａ、４ｂは複数段にわたって設けられるため、液体は各溝部４ａ、４ｂで大きなせん断力が加わって攪拌される。このため、分離液状ドレッシング１０を振る力や回数が少ない場合であっても水相部と油相部とが極めて細かく分散してエマルション状態に近い状態の分散液を作成することができる。 When the vortices 21a, 21b, 22a, 22b are destroyed and disappear, a large shearing force is generated in the liquid. Since the groove portions 4a and 4b are provided in a plurality of stages, the liquid is stirred by applying a large shearing force to each of the groove portions 4a and 4b. For this reason, even if it is a case where the force and frequency | count of shaking the separated liquid dressing 10 are few, a water phase part and an oil phase part can disperse | distribute very finely, and the dispersion liquid of the state close | similar to an emulsion state can be created.
図７（ａ）〜（ｋ）は、攪拌用容器１の攪拌による分散の効果を可視化するための実験結果を示す図である。各図において右側は本実施形態の攪拌用容器１を示し、左側は比較のため内筒３を省いた状態を示している。攪拌用容器１内の液体は水相部として水道水を用いるとともに油相部として市販のオリーブオイルを用い、水相部と油相部との体積比を１：１にしている。 FIGS. 7A to 7K are diagrams showing experimental results for visualizing the effect of dispersion by stirring of the stirring container 1. In each figure, the right side shows the stirring container 1 of the present embodiment, and the left side shows a state in which the inner cylinder 3 is omitted for comparison. The liquid in the stirring vessel 1 uses tap water as the water phase part and commercial olive oil as the oil phase part, and the volume ratio of the water phase part to the oil phase part is 1: 1.
図７（ａ）は攪拌前の状態を示している。図７（ｂ）は軸方向の振幅を１０ｃｍとして攪拌用容器１を１０回振って攪拌した直後の状態を示している。図７（ｃ）〜（ｋ）は攪拌用容器１を攪拌してから１５秒後、３０秒後、６０秒後、９０秒後、１２０秒後、１５０秒後、１８０秒後、１０分後、２０分後の様子をぞれぞれ示している。 FIG. 7A shows a state before stirring. FIG. 7B shows a state immediately after stirring by shaking the stirring container 1 10 times with an axial amplitude of 10 cm. FIGS. 7 (c) to 7 (k) are 15 seconds, 30 seconds, 60 seconds, 90 seconds, 120 seconds, 150 seconds, 150 seconds, 180 seconds, 10 minutes after stirring the stirring vessel 1. , 20 minutes later.
攪拌用容器１の攪拌直後では本実施形態及び比較例共に液体が分散した状態になっている。比較例では攪拌後１５秒が経過すると水相部と油相部の分離が開始され、１８０秒後にはほぼ完全に二相に分離した。これに対し、本実施形態の攪拌用容器１では攪拌後２０分が経過しても水相部と油相部の分離が開始されていない。即ち、混濁復帰時間が本実施形態により著しく増加した。 Immediately after stirring the stirring container 1, the liquid is dispersed in both the present embodiment and the comparative example. In the comparative example, separation of the water phase portion and the oil phase portion started after 15 seconds from stirring, and after 180 seconds, separation into two phases almost completely. On the other hand, in the stirring container 1 of this embodiment, the separation of the water phase part and the oil phase part has not started even after 20 minutes have passed since stirring. That is, the turbidity recovery time is significantly increased by this embodiment.
また、内部の液体の粒径ついて調べると、本実施形態では非常に細かい粒径であったのに対して比較例では比較的大きな粒径になっていた。比較例の攪拌用容器１を更に３倍以上の時間をかけて攪拌を行ったが液体の粒径は細かくならず、混濁復帰時間もほとんど延長しなかった。 Further, when the particle size of the liquid inside was examined, it was a very small particle size in the present embodiment, whereas the comparative example had a relatively large particle size. The stirring vessel 1 of the comparative example was further stirred for 3 times or more, but the liquid particle size did not become fine and the turbidity recovery time was hardly prolonged.
以上の結果より、本実施形態の攪拌用容器１は内部の液体に与えるせん断力が大幅に増加して強い混合攪拌が得られていることが解る。これにより、エマルションに近いクリーミーな状態の分散液が容易に生成される。 From the above results, it can be seen that in the stirring container 1 of the present embodiment, the shearing force applied to the liquid inside is greatly increased and strong mixing and stirring is obtained. Thereby, the dispersion liquid of the creamy state close | similar to an emulsion is produced | generated easily.
本実施形態によると、内筒３の外周面３ａ及び内周面３ｂに軸方向に周期Ｔで並設される溝部４ａ、４ｂを設けたので、攪拌用容器１を軸方向に振ることによって溝部４ａ、４ｂ内に渦２１ａ、２１ｂ形成される。このため、直前に形成された回転方向が逆方向の渦２２ａ、２２ｂが破壊されて液体に大きなせん断力が働く。従って、振る力や回数を少なくしても、分離液状ドレッシング１０の内容物８を充分分散させることができる。その結果、女性、子供、高齢者等の力の弱い使用者の場合でも容易に攪拌することができる。 According to the present embodiment, since the grooves 4a and 4b are provided on the outer peripheral surface 3a and the inner peripheral surface 3b of the inner cylinder 3 so as to be arranged in parallel in the cycle T in the axial direction, the groove portions are obtained by shaking the stirring vessel 1 in the axial direction. Vortices 21a and 21b are formed in 4a and 4b. For this reason, the vortices 22a and 22b formed immediately before and having the opposite rotation directions are broken, and a large shearing force is applied to the liquid. Therefore, the content 8 of the separation liquid dressing 10 can be sufficiently dispersed even if the force and number of shaking are reduced. As a result, even a weak user such as a woman, a child, or an elderly person can be easily stirred.
尚、周期Ｔは一定でなくてもよい。また、内筒３の外周面３ａの溝部４ａ及び内周面３ｂの溝部４ｂの一方を省いても同様に、内容物８に大きなせん断力を与えて内容物８を充分分散させることができる。内筒３の外周面３ａの溝部４ａ及び内周面３ｂの溝部４ｂの両方を設けると、より多くの渦が形成されて内容物８を更に分散させることができる。 Note that the period T may not be constant. Further, even if one of the groove 4a on the outer peripheral surface 3a and the groove 4b on the inner peripheral surface 3b is omitted, the content 8 can be sufficiently dispersed by applying a large shearing force to the content 8. If both the groove 4a on the outer peripheral surface 3a of the inner cylinder 3 and the groove 4b on the inner peripheral surface 3b are provided, more vortices are formed and the contents 8 can be further dispersed.
また、内筒３の周壁を屈曲して溝部４ａ、４ｂを内筒３の内周面及び外周面に設け、内周側の溝部４ｂと外周側の溝部４ａとが共通の側壁を有するので、内筒３の両面の溝部４ａ、４ｂを薄肉の樹脂成型品によって容易に形成することができる。これにより、外筒３の内部の内容積を大きく確保できる。 Also, the peripheral wall of the inner cylinder 3 is bent to provide the grooves 4a and 4b on the inner peripheral surface and the outer peripheral surface of the inner cylinder 3, and the inner peripheral groove 4b and the outer peripheral groove 4a have a common side wall. The groove portions 4a and 4b on both surfaces of the inner cylinder 3 can be easily formed with thin resin molded products. Thereby, a large internal volume inside the outer cylinder 3 can be secured.
また、内筒３の内側と外側とを連通させる切欠き３ｃ（連通部）を下部に設けたので、内筒３の内側と外側とに存在する液体や液体に浮遊する固形物が連通部を介して互いに行き来する。連通部が設けられないと、内筒３の内側の液体に与えられるせん断力と外側の液体に与えられるせん断力とに差が生じて両者の分散度合いが異なる場合がある。連通部を設けることにより、内筒３の内外の物質が互いに行き来して分散度合いを平均化することができる。従って、よりクリーミーな分散液を生成することができる。 Moreover, since the notch 3c (communication part) which connects the inner side and the outer side of the inner cylinder 3 is provided in the lower part, the liquid which exists in the inner side and the outer side of the inner cylinder 3, and the solid substance which floats on a liquid connect a communication part. Go back and forth through each other. If the communication portion is not provided, there may be a difference between the shearing force applied to the liquid inside the inner cylinder 3 and the shearing force applied to the liquid outside, and the degree of dispersion between them may be different. By providing the communication portion, the substances inside and outside the inner cylinder 3 can come and go to each other and the degree of dispersion can be averaged. Therefore, a creamy dispersion can be produced.
また、本実施形態では溝部４ａ、４ｂの幅Ｗと深さＤを５ｍｍに形成している。溝部４ａ、４ｂの幅Ｗに対して深さＤが著しく小さい場合や大きい場合は溝部４ａ、４ｂ内に渦が生じにくくなる。このため、液体に働くせん断力が大幅に低下して充分分散させることができない。従って、溝部４ａ、４ｂの幅Ｗと深さＤとを略同じにするとより望ましい。この時、溝部４ａ、４ｂの周期Ｔを幅Ｗの２倍にすると最も効率よく溝４ａ、４ｂを配置することができる。 In the present embodiment, the widths W and depths D of the grooves 4a and 4b are 5 mm. When the depth D is remarkably small or large with respect to the width W of the groove portions 4a and 4b, vortices are hardly generated in the groove portions 4a and 4b. For this reason, the shear force acting on the liquid is greatly reduced and cannot be sufficiently dispersed. Therefore, it is more desirable that the width W and the depth D of the groove portions 4a and 4b are substantially the same. At this time, when the period T of the groove portions 4a and 4b is twice the width W, the grooves 4a and 4b can be arranged most efficiently.
溝部４ａ、４ｂの幅Ｗ及び深さＤは内容物８の粘性に応じて適切な長さが選択される。即ち、内容物の粘性が比較的小さい場合には溝部４ａ、４ｂの幅Ｗ及び深さＤは比較的小さい方が望ましい。内容物の粘性が比較的大きい場合には溝部４ａ、４ｂの幅Ｗ及び深さＤは比較的大きい方が望ましい。 Appropriate lengths are selected for the widths W and depths D of the grooves 4 a and 4 b according to the viscosity of the contents 8. That is, when the viscosity of the contents is relatively small, it is desirable that the width W and the depth D of the grooves 4a and 4b are relatively small. When the viscosity of the contents is relatively large, it is desirable that the width W and the depth D of the grooves 4a and 4b are relatively large.
本実施形態では内容物８が酢とオイルとを含み、溝部４ａ、４ｂの幅Ｗを５ｍｍに形成して充分分散させることができる。このため、溝部４ａ、４ｂの幅Ｗを５ｍｍ以上にすると、水溶性の液体やオイルを含む内容物に対して充分分散させることができる。 In this embodiment, the contents 8 contain vinegar and oil, and the width W of the grooves 4a and 4b can be formed to 5 mm to be sufficiently dispersed. For this reason, when the width W of the groove portions 4a and 4b is 5 mm or more, the groove portions 4a and 4b can be sufficiently dispersed with respect to the contents containing water-soluble liquid or oil.
例えば内容物８にゴマや玉ねぎの破砕物等の固形物が含まれる場合には、これらが溝部４ａ、４ｂに詰まって渦２１ａ、２１ｂ、２２ａ、２２ｂの生成が妨げられる。このため、溝部４ａ、４ｂの幅Ｗは少なくとも固形物の大きさの２〜３倍程度にすべきである。但し、溝部４ａ、４ｂの幅Ｗを必要以上に大きくすると、内筒３に形成される溝部４ａ、４ｂの数が減少する。これにより、生成される渦２１ａ、２１ｂ、２２ａ、２２ｂの数も減少してせん断力が低下する。このため、分離液状ドレッシング１０等の固形物が含まれる場合には、溝部４ａ、４ｂの幅Ｗは固形物が詰まらない程度の大きさを確保できる範囲のうち最小にすべきである。 For example, when the contents 8 contain solids such as sesame or onion crushed material, these are clogged in the grooves 4a and 4b, thereby preventing the formation of the vortices 21a, 21b, 22a and 22b. For this reason, the width W of the grooves 4a and 4b should be at least about 2 to 3 times the size of the solid matter. However, if the width W of the groove portions 4a and 4b is increased more than necessary, the number of groove portions 4a and 4b formed in the inner cylinder 3 is reduced. Thereby, the number of vortices 21a, 21b, 22a, and 22b to be generated is also reduced, and the shearing force is reduced. For this reason, when a solid material such as the separated liquid dressing 10 is included, the width W of the groove portions 4a and 4b should be minimized within a range in which a size that does not clog the solid material can be secured.
また、内容物８に固形物が含まれない場合には、溝部４ａ、４ｂの深さＤ及び幅Ｗを５ｍｍ以下にしてもよい。尚、上下する流体の流路の間隔、溝部４ａ、４ｂの深さ、溝部４ａ、４ｂの幅Ｗを略同一にすると最も効率がよい。流路の間隔が広すぎる場合には、せん断力を流体に付与する領域の全体に対する割合が小さくなるため、せん断力を効率的に与えることができなくなる。よって、流路の間隔が広すぎる場合には、内筒を必要に応じて２重、３重等の多重にして流路の間隔（陸部と陸部の隙間）と溝部の深さ、溝部の幅が略同一になるように調整すべきである。 Moreover, when the solid content is not contained in the content 8, you may make the depth D and width W of the groove parts 4a and 4b into 5 mm or less. In addition, it is most efficient when the distance between the flow paths of the fluid that moves up and down, the depth of the grooves 4a and 4b, and the width W of the grooves 4a and 4b are substantially the same. When the interval between the flow paths is too wide, the ratio of the whole area to which the shearing force is applied to the fluid becomes small, so that the shearing force cannot be efficiently applied. Therefore, if the distance between the flow paths is too wide, the inner cylinder is doubled, tripled, etc. as necessary, and the distance between the flow paths (gap between the land part and the land part), the depth of the groove part, and the groove part Should be adjusted so that their widths are substantially the same.
分離液状ドレッシング１０の包装容器では溝部４ａ、４ｂの深さＤ及び幅Ｗを５ｍｍ程度にすると良好であり、１０ｍｍ程度までは十分な効果が得られる。１０ｍｍ以上にすると、溝部４ａ、４ｂの数が減少するため望ましくない。これらは、分離液状ドレッシング１０の攪拌用容器の断面が直径６０ｍｍの円の場合の結果である。この場合、外筒２の内周面と内筒３の外周面３ａの陸部５ａの間隔が１０ｍｍ、溝部４ａ、４ｂの深さが１０ｍｍ、内筒３の内周面３ｂの陸部５ｂと内筒３の中心までの距離が１０ｍｍとなり、最も効率的な配置が可能となる。 In the packaging container of the separated liquid dressing 10, it is preferable that the depth D and the width W of the grooves 4a and 4b are about 5 mm, and a sufficient effect is obtained up to about 10 mm. If it is 10 mm or more, the number of the grooves 4a and 4b decreases, which is not desirable. These are the results when the cross section of the stirring vessel of the separation liquid dressing 10 is a circle having a diameter of 60 mm. In this case, the distance between the inner peripheral surface of the outer cylinder 2 and the land portion 5a of the outer peripheral surface 3a of the inner cylinder 3 is 10 mm, the depth of the grooves 4a and 4b is 10 mm, and the land portion 5b of the inner peripheral surface 3b of the inner cylinder 3 The distance to the center of the inner cylinder 3 is 10 mm, and the most efficient arrangement is possible.
即ち、外筒２の断面にかかる代表長さをＬとして、溝部４ａ、４ｂの幅Ｗ、溝部４ａ、４ｂの深さＤ、外筒２の内周面と内筒３の外周面３ａの陸部５ａとの距離をそれぞれＬ／６程度にすると効率的な配置になる。ここで、代表長さＬは断面が円の場合は直径、断面が矩形の場合は一辺の長さになる。また、これらをＬ／８以上程度に設定すれば高い効果が得られる。 That is, assuming that the representative length of the cross section of the outer cylinder 2 is L, the width W of the grooves 4a and 4b, the depth D of the grooves 4a and 4b, the land surface of the inner peripheral surface of the outer cylinder 2 and the outer peripheral surface 3a of the inner cylinder 3 When the distance to the part 5a is about L / 6, the arrangement is efficient. Here, the representative length L is the diameter when the cross section is a circle, and the length of one side when the cross section is a rectangle. If these are set to about L / 8 or more, a high effect can be obtained.
また、溝部４ａ、４ｂの幅ＷをＬ／２よりも大きくすると、溝部４ａ、４ｂの幅Ｗと深さＤを略同一にできない。このため、溝部４ａ、４ｂに生成される渦２１ａ、２１ｂ、２２ａ、２２ｂが楕円になるため渦の生成効率が低下するか、渦の強度が弱くなる。更に、内筒３に形成される溝部４ａ、４ｂの数が減少して生成される渦の数も減少し、せん断力が低下する。従って、溝部４ａ、４ｂの幅ＷをＬ／８以上Ｌ／２以下にするとよい。 Further, if the width W of the groove portions 4a and 4b is larger than L / 2, the width W and the depth D of the groove portions 4a and 4b cannot be made substantially the same. For this reason, since the vortices 21a, 21b, 22a, and 22b generated in the groove portions 4a and 4b are oval, the generation efficiency of the vortex is reduced or the strength of the vortex is weakened. Furthermore, the number of grooves 4a and 4b formed in the inner cylinder 3 is reduced, so that the number of vortices generated is reduced and the shearing force is reduced. Therefore, the width W of the groove portions 4a and 4b is preferably set to L / 8 or more and L / 2 or less.
また、溝部４ａ、４ｂは側壁が傾斜した断面Ｖ字型やアーチ型に形成してもよいが、本実施形態のように溝部４ａ、４ｂの側壁が軸方向に対して垂直な断面矩形に形成するとより望ましい。即ち、溝部４ａ、４ｂの側壁が軸方向に対して垂直であるため、内容物８の軸方向の往復運動に随伴する液体の流れと、溝部４ａ、４ｂの側壁とが垂直になる。これにより、液体の流れが溝部４ａ、４ｂの側壁で効率よく剥離して溝部４ａ、４ｂに流体が効率よく回り込む。このため、溝部４ａ、４ｂの中に強い渦を効率よく生成することができる。生成される渦の強度が強いほど液体に対して与えるせん断が大きくなるため、内容物８を更に分散させることができる。 Further, the grooves 4a and 4b may be formed in a V-shaped section or an arch shape in which the side walls are inclined, but the side walls of the groove sections 4a and 4b are formed in a cross-sectional rectangle perpendicular to the axial direction as in this embodiment. It is more desirable. That is, since the side walls of the groove portions 4a and 4b are perpendicular to the axial direction, the liquid flow accompanying the reciprocating motion of the contents 8 in the axial direction and the side walls of the groove portions 4a and 4b become vertical. As a result, the liquid flow efficiently separates at the side walls of the groove portions 4a and 4b, and the fluid efficiently wraps around the groove portions 4a and 4b. For this reason, a strong vortex can be efficiently generated in the grooves 4a and 4b. As the strength of the generated vortex increases, the shear applied to the liquid increases, so that the contents 8 can be further dispersed.
また、溝部４ａ、４ｂの側壁は開放側の端部の曲率半径が大きいと液体の流れが円滑に溝部４ａ、４ｂ内に流入して強い渦が生成されない。このため、溝部４ａ、４ｂの側壁は開放側の端部の曲率半径が１ｍｍ以下に形成される。これにより、液体の流れがより効率よく剥離して強い渦を発生させることができ、内容物８を更に分散させることができる。 Further, when the curvature radius of the open end portion of the side walls of the groove portions 4a and 4b is large, the liquid flow smoothly flows into the groove portions 4a and 4b and a strong vortex is not generated. For this reason, the side walls of the grooves 4a and 4b are formed so that the radius of curvature of the end on the open side is 1 mm or less. Thereby, the flow of the liquid can be more efficiently separated to generate a strong vortex, and the contents 8 can be further dispersed.
外筒２はガラスやポリエチレンテレフタラート（ＰＥＴ）等の透明材料から成るので、容易に内容物８の攪拌状態を確認することができる。内筒３がポリエチレンテレフタラート（ＰＥＴ）等の透明樹脂から成るので内容物８の攪拌状態をより詳細に確認することができる。外筒２や内筒３は少なくとも一部が透明であればよく、内容物８に対して影響がなければ成形が容易なポリエチレン（ＰＥ）やポリプロピレン（ＰＰ）等を用いてもよい。また、撹拌状態を確認する必要がなければ陶磁器等のセラミック材料や金属材料を用いてもよい。 Since the outer cylinder 2 is made of a transparent material such as glass or polyethylene terephthalate (PET), the stirring state of the contents 8 can be easily confirmed. Since the inner cylinder 3 is made of a transparent resin such as polyethylene terephthalate (PET), the stirring state of the contents 8 can be confirmed in more detail. The outer cylinder 2 and the inner cylinder 3 may be at least partially transparent, and polyethylene (PE), polypropylene (PP), or the like that can be easily molded as long as the contents 8 are not affected may be used. Further, if it is not necessary to check the stirring state, a ceramic material such as ceramics or a metal material may be used.
尚、溝部４ａ、４ｂが環状に形成されるが、内筒３の軸方向に所定の周期で並設されていれば螺旋状に形成してもよい。 The grooves 4a and 4b are formed in a ring shape, but may be formed in a spiral shape as long as they are arranged in parallel in the axial direction of the inner cylinder 3 at a predetermined period.
次に、図８は第２実施形態の攪拌用容器を示す側面断面図である。説明の便宜上、前述の図１〜図７に示す第１実施形態と同一の部分は同一の符号を付している。本実施形態は第１実施形態の内筒３が省かれ、外筒２の内周面２ｂに複数の環状の溝部４ｃが軸方向に所定の周期で並設されている。その他の部分は第１実施形態と同様である。 Next, FIG. 8 is a side sectional view showing a stirring container according to a second embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In this embodiment, the inner cylinder 3 of the first embodiment is omitted, and a plurality of annular grooves 4c are arranged in parallel in the axial direction on the inner peripheral surface 2b of the outer cylinder 2 at a predetermined period. Other parts are the same as those in the first embodiment.
外筒２はポリエチレンテレフタラート（ＰＥＴ）等の透明樹脂により形成されている。これにより、攪拌状態を容易に視認できる。内容物８（図９参照）に対して影響がなければポリエチレン（ＰＥ）やポリプロピレン（ＰＰ）等を用いてもよい。内部の視認の必要がない場合は不透明な材料により外筒２を形成してもよい。溝部４ｃは外筒２と同時成形によって形成され、幅Ｗが５ｍｍ、深さＤが５ｍｍ、周期Ｔが１０ｍｍで形成されている。 The outer cylinder 2 is formed of a transparent resin such as polyethylene terephthalate (PET). Thereby, a stirring state can be visually recognized easily. Polyethylene (PE), polypropylene (PP), or the like may be used as long as it does not affect the contents 8 (see FIG. 9). When there is no need to visually recognize the inside, the outer cylinder 2 may be formed of an opaque material. The groove 4c is formed by simultaneous molding with the outer cylinder 2, and is formed with a width W of 5 mm, a depth D of 5 mm, and a period T of 10 mm.
外筒２内には第１実施形態と同様の内容物８（図９参照）が入れられ、攪拌用容器１を包装容器とする分離液状ドレッシング１０（図９参照）が得られる。 The same contents 8 (see FIG. 9) as in the first embodiment are placed in the outer cylinder 2, and a separated liquid dressing 10 (see FIG. 9) using the stirring container 1 as a packaging container is obtained.
図９、図１０は分離液状ドレッシング１０を振った時の状態を説明する図である。分離液状ドレッシング１０を長手方向に振ると、上方に移動させる期間と下方に移動させる期間とが交互に繰り返される。分離液状ドレッシング１０が矢印Ａ１に示すように上方に移動すると内容物８は慣性力を受けて矢印Ｂ１に示すように下方に移動する。また、分離液状ドレッシング１０が矢印Ａ２に示すように下方に移動すると内容物８は矢印Ｂ２に示すように上方に移動する。 9 and 10 are diagrams for explaining a state when the separated liquid dressing 10 is shaken. When the separated liquid dressing 10 is shaken in the longitudinal direction, the period of moving upward and the period of moving downward are alternately repeated. When the separated liquid dressing 10 moves upward as indicated by an arrow A1, the content 8 receives an inertial force and moves downward as indicated by an arrow B1. Further, when the separated liquid dressing 10 moves downward as indicated by an arrow A2, the content 8 moves upward as indicated by an arrow B2.
図１１、図１２はそれぞれ図９のＦ部詳細図及び図１０のＧ部詳細図になっている。内容物８が矢印Ｂ１の方向に移動すると、図１１に示すように外筒２の内周面２ｂに沿って流通する液体は溝部４ｃ内に流入する。これにより、溝部４ｃ内には図中、時計回りに回転する渦２１ｃが形成される。 FIG. 11 and FIG. 12 are a detailed view of F section in FIG. 9 and a detailed view of G section in FIG. When the contents 8 move in the direction of the arrow B1, the liquid flowing along the inner peripheral surface 2b of the outer cylinder 2 flows into the groove 4c as shown in FIG. As a result, a vortex 21c that rotates clockwise in the figure is formed in the groove 4c.
その直後に内容物８が矢印Ｂ２の方向に移動すると、図１２に示すように、溝部４ｃ内には図中、反時計回りの渦２２ｃが形成される。即ち、溝部４ｃに流入する液体は直前に形成された渦２１ｃを打ち消すように作用してこれを破壊して消滅させ、溝部４ｃ内に逆方向に回転する渦２２ｃが発達する。 Immediately thereafter, when the contents 8 move in the direction of the arrow B2, as shown in FIG. 12, a counterclockwise vortex 22c in the figure is formed in the groove 4c. That is, the liquid flowing into the groove 4c acts so as to cancel the vortex 21c formed immediately before, destroys it and disappears, and the vortex 22c rotating in the reverse direction develops in the groove 4c.
その直後に内容物８が矢印Ｂ１の方向に移動すると、上記と同様に溝部４ｃ内に渦２１ｃが形成される。即ち、溝部４ｃに流入する液体は直前に形成された渦２２ｃを打ち消すように作用してこれを破壊して消滅させ、溝部４ｃ内に逆方向に回転する渦２１ｃが発達する。以降、これらの動作が繰り返される。 Immediately after that, when the contents 8 move in the direction of the arrow B1, a vortex 21c is formed in the groove 4c as described above. That is, the liquid flowing into the groove 4c acts so as to cancel the vortex 22c formed immediately before, destroys it and disappears, and the vortex 21c rotating in the reverse direction develops in the groove 4c. Thereafter, these operations are repeated.
渦２１ｃ、２２ｃが破壊されて消滅する際には液体に大きなせん断力が発生する。溝部４ｃは複数段にわたって設けられるため、液体は各溝部４ｃで大きなせん断力が加わって攪拌される。このため、分離液状ドレッシング１０を振る力や回数が少ない場合であっても水相部と油相部とが極めて細かく分散してエマルション状態に近い状態の分散液を作成することができる。 When the vortices 21c and 22c are destroyed and disappear, a large shearing force is generated in the liquid. Since the groove 4c is provided in a plurality of stages, the liquid is agitated by applying a large shearing force in each groove 4c. For this reason, even if it is a case where the force and frequency | count of shaking the separated liquid dressing 10 are few, a water phase part and an oil phase part can disperse | distribute very finely, and the dispersion liquid of the state close | similar to an emulsion state can be created.
本実施形態によると、外筒２の内周面２ｂに軸方向に周期Ｔで並設される溝部４ｃを設けたので、攪拌用容器１を軸方向に振ることによって溝部４ｃ内に渦２１ｃ形成される。このため、直前に形成された回転方向が逆方向の渦２２ｃが破壊されて液体に大きなせん断力が働く。従って、振る力や回数を少なくしても、分離液状ドレッシング１０の内容物８を充分分散させることができる。その結果、女性、子供、高齢者等の力の弱い使用者の場合でも容易に攪拌することができる。 According to the present embodiment, since the groove portion 4c arranged in parallel with the period T in the axial direction is provided on the inner peripheral surface 2b of the outer cylinder 2, the vortex 21c is formed in the groove portion 4c by shaking the stirring vessel 1 in the axial direction. Is done. For this reason, the vortex 22c formed in the immediately opposite direction of rotation is broken and a large shearing force acts on the liquid. Therefore, the content 8 of the separation liquid dressing 10 can be sufficiently dispersed even if the force and number of shaking are reduced. As a result, even a weak user such as a woman, a child, or an elderly person can be easily stirred.
また、溝部４ｃの幅Ｗと深さＤとを略同じにすると内容物８を更に分散させることができる。外筒３の代表長さをＬとして溝部４ｃの幅ＷをＬ／８以上Ｌ／２以下にすると、水溶性の液体やオイルを含む内容物に対して更に分散させることができる。また、溝部４ｃの側壁が軸方向に対して垂直な断面矩形に形成すると生成される渦の強度が強くなり、内容物８を更に分散させることができる。加えて、溝部４ｃの側壁は開放側の端部の曲率半径が１ｍｍ以下に形成されるので、内容物８を更に分散させることができる。 Further, if the width W and the depth D of the groove 4c are substantially the same, the contents 8 can be further dispersed. When the representative length of the outer cylinder 3 is L and the width W of the groove 4c is not less than L / 8 and not more than L / 2, the outer cylinder 3 can be further dispersed with respect to the contents containing water-soluble liquid or oil. Further, when the side wall of the groove 4c is formed in a rectangular cross section perpendicular to the axial direction, the strength of the generated vortex is increased and the contents 8 can be further dispersed. In addition, since the radius of curvature of the end portion on the open side is formed to be 1 mm or less, the contents 8 can be further dispersed.
尚、溝部４ｃが環状に形成されるが、外筒２の軸方向に所定の周期で並設されていれば螺旋状に形成してもよい。また、周期Ｔは一定でなくてもよい。 In addition, although the groove part 4c is formed in cyclic | annular form, as long as it arranges in parallel by the predetermined period in the axial direction of the outer cylinder 2, you may form in a spiral shape. Further, the period T may not be constant.
次に、図１３は第３実施形態の攪拌用容器を示す側面断面図である。説明の便宜上、前述の図１〜図１２に示す第１、第２実施形態と同一の部分は同一の符号を付している。本実施形態は第１実施形態と同様の内筒３が設けられ、第２実施形態と同様の溝部４ｃが設けられる。その他の部分は第１実施形態と同様である。 Next, FIG. 13 is a side sectional view showing a stirring container according to a third embodiment. For convenience of explanation, the same parts as those in the first and second embodiments shown in FIGS. 1 to 12 are given the same reference numerals. In the present embodiment, an inner cylinder 3 similar to that in the first embodiment is provided, and a groove 4c similar to that in the second embodiment is provided. Other parts are the same as those in the first embodiment.
本実施形態によると、内筒３の外周面３ａ及び内周面３ｂに溝部４ａ、４ｂが形成され、外筒２の内周面２ｂに溝部４ｃが形成される。このため、第１、第２実施形態に比してより多くの溝部を設けることができ、溝部によって発生する渦も増加して液体にはより大きなせん断力が働く。従って、振る力や回数を少なくしても、分離液状ドレッシング１０の内容物８を充分分散させることができる。 According to this embodiment, the grooves 4 a and 4 b are formed on the outer peripheral surface 3 a and the inner peripheral surface 3 b of the inner cylinder 3, and the groove 4 c is formed on the inner peripheral surface 2 b of the outer cylinder 2. For this reason, as compared with the first and second embodiments, more grooves can be provided, and vortices generated by the grooves also increase, so that a larger shear force acts on the liquid. Therefore, the content 8 of the separation liquid dressing 10 can be sufficiently dispersed even if the force and number of shaking are reduced.
また、内筒３の外周面３ａの溝部４ａと外筒２の内周面２ｂの溝部４ｃとが対向配置される。内筒３の外周面３ａの陸部５ａ（図１参照）と溝部４ｃとが対向すると、外筒２と内筒３間を流通する液体は溝部４ａ、４ｃを蛇行して渦の形成が弱くなる。従って、溝部４ａ、４ｃを対向配置することにより、強い渦を発生させることができる。 Further, the groove portion 4 a of the outer peripheral surface 3 a of the inner cylinder 3 and the groove portion 4 c of the inner peripheral surface 2 b of the outer cylinder 2 are arranged to face each other. When the land portion 5a (see FIG. 1) on the outer peripheral surface 3a of the inner cylinder 3 and the groove portion 4c face each other, the liquid flowing between the outer tube 2 and the inner tube 3 meanders the groove portions 4a and 4c and weakly forms vortices. Become. Therefore, a strong vortex can be generated by arranging the grooves 4a and 4c so as to face each other.
次に、図１４は第４実施形態の攪拌用容器を示す側面断面図である。説明の便宜上、前述の図１〜図１３に示す第１〜第３実施形態と同一の部分は同一の符号を付している。本実施形態は第３実施形態に加えて内筒３の内側に更に内筒９が設けられる。その他の部分は第３実施形態と同様である。 Next, FIG. 14 is a side sectional view showing a stirring container according to a fourth embodiment. For convenience of explanation, the same parts as those in the first to third embodiments shown in FIGS. 1 to 13 are given the same reference numerals. In the present embodiment, an inner cylinder 9 is further provided inside the inner cylinder 3 in addition to the third embodiment. Other parts are the same as those of the third embodiment.
内筒９は内筒３よりも小さい内径で、内筒３と同様の溝部４ｄ、４ｅが外周面９ａ及び内周面９ｂにそれぞれ設けられる。内筒９の下端には内筒３の切欠き３ｃ（図２参照）と同様の切欠き（不図示）が設けられる。 The inner cylinder 9 has an inner diameter smaller than that of the inner cylinder 3, and grooves 4d and 4e similar to the inner cylinder 3 are provided on the outer peripheral surface 9a and the inner peripheral surface 9b, respectively. The lower end of the inner cylinder 9 is provided with a notch (not shown) similar to the notch 3c (see FIG. 2) of the inner cylinder 3.
本実施形態によると、第３実施形態に比して更に多くの溝部を設けることができ、溝部によって発生する渦も増加して液体にはより大きなせん断力が働く。従って、振る力や回数を少なくしても、分離液状ドレッシング１０の内容物８を充分分散させることができる。 According to the present embodiment, more grooves can be provided as compared with the third embodiment, and vortices generated by the grooves also increase, and a larger shearing force acts on the liquid. Therefore, the content 8 of the separation liquid dressing 10 can be sufficiently dispersed even if the force and number of shaking are reduced.
また、内筒３の内周面３ｂの溝部４ｂと内筒９の外周面９ａの溝部４ｄとが対向配置される。内筒３の内周面３ｂの陸部５ｂ（図１参照）と溝部４ｄとが対向すると、内筒３、９間を流通する液体は溝部４ｃ、４ｄを蛇行して渦の形成が弱くなる。従って、溝部４ｂ、４ｄを対向配置することにより、強い渦を発生させることができる。 Further, the groove portion 4b of the inner peripheral surface 3b of the inner cylinder 3 and the groove portion 4d of the outer peripheral surface 9a of the inner cylinder 9 are arranged to face each other. When the land portion 5b (see FIG. 1) of the inner peripheral surface 3b of the inner cylinder 3 and the groove portion 4d face each other, the liquid flowing between the inner cylinders 3 and 9 meanders the groove portions 4c and 4d and weakens the formation of vortices. . Therefore, a strong vortex can be generated by arranging the grooves 4b and 4d to face each other.
尚、内容物８の粘性が比較的大きい場合には、流動性が悪くなって液体に働くせん断力が低下する場合がある。このため、比較的粘性の小さな内容物を選択するべきである。 In addition, when the viscosity of the content 8 is comparatively large, fluidity | liquidity may worsen and the shear force which acts on a liquid may fall. For this reason, contents with relatively low viscosity should be selected.
第１〜第４実施形態において、外筒２及び内筒３が円筒形に形成されるが、角柱形に形成してもよい。また、攪拌用容器１によって複数の液体から分散液を生成しているが、固体粒子の粉体と液体とを外筒２内に入れて分散液（懸濁液）を生成してもよい。また、溶質を溶媒に溶かす溶液生成手段として第１〜第４実施形態の攪拌用容器１を用いても同様の効果を得ることができる。 In the first to fourth embodiments, the outer cylinder 2 and the inner cylinder 3 are formed in a cylindrical shape, but may be formed in a prismatic shape. Moreover, although the dispersion liquid is produced | generated from the some liquid with the container 1 for stirring, you may produce | generate a dispersion liquid (suspension) by putting the powder and liquid of a solid particle in the outer cylinder 2. FIG. Moreover, the same effect can be acquired even if it uses the container 1 for stirring of 1st-4th embodiment as a solution production | generation means which dissolves a solute in a solvent.
また、攪拌用容器１は分離液状ドレッシング１０の包装容器として用いられるが、他の包装容器として用いてもよい。例えば、攪拌用容器１を純水とオイル成分とを含む分離液状の化粧品の包装容器としてもよい。また、例えば難水溶性医薬品と生理食塩水とを含む医薬品の包装容器としてもよく、難水溶性医薬品を生理食塩水に溶解させるための溶解用容器としてもよい。この場合、難水溶性医薬品を生理食塩水に溶かすための溶解促進剤（アルコールや界面活性剤等の副作用のある物質）の使用量の減少させることや使用を無くすことができる。 In addition, the stirring container 1 is used as a packaging container for the separated liquid dressing 10, but may be used as another packaging container. For example, the stirring container 1 may be a packaging container for a separated liquid cosmetic containing pure water and an oil component. In addition, for example, a medicine packaging container containing a poorly water-soluble medicine and physiological saline may be used, or a dissolution container for dissolving the poorly water-soluble medicine in physiological saline. In this case, it is possible to reduce or eliminate the use of a dissolution accelerator (a substance having a side effect such as an alcohol or a surfactant) for dissolving a poorly water-soluble drug in physiological saline.
また、洗濯機における洗剤と水との混合を促進する洗剤の高度溶解装置に攪拌用容器１を用いてもよい。コーヒーの抽出などの固体に含まれる可溶成分の液媒体への抽出装置に攪拌用容器１を用いてもよい。液状二酸化炭素または超臨界二酸化炭素で物質抽出や溶解を行う装置での混合促進や、使用する溶解助剤（エントレーナ）と二酸化炭素の混合促進のために攪拌用容器１を用いてもよい。 Moreover, you may use the container 1 for stirring for the high melt | dissolution apparatus of the detergent which accelerates | stimulates mixing of the detergent and water in a washing machine. The agitation container 1 may be used in an apparatus for extracting soluble components contained in a solid, such as coffee extraction, into a liquid medium. The stirring vessel 1 may be used for promoting mixing in an apparatus that performs substance extraction or dissolution with liquid carbon dioxide or supercritical carbon dioxide, and for promoting mixing of a dissolution aid (entrainer) to be used with carbon dioxide.
また、液体の混合だけでなく、牛乳からチーズやバターを分離して生成する場合のように、液体から固体を分離する成分分離過程に攪拌用容器１を用いてもよい。これにより、弱い力で効率的に攪拌することによって乳脂肪や蛋白質の良質な凝集・分離を促進することができる。 Moreover, you may use the container 1 for stirring not only in liquid mixing but in the component separation process which isolate | separates solid from a liquid like the case where cheese and butter are isolate | separated and produced | generated from milk. Thereby, high-quality aggregation and separation of milk fat and protein can be promoted by efficiently stirring with a weak force.
以上の例に示すように、本発明の主旨を逸脱しない範囲で適宜の変更を加えて実施することができる。 As shown in the above examples, the present invention can be implemented with appropriate changes without departing from the gist of the present invention.
