Description

本発明は、容器の円筒形状口頸部に装着して、収容している混合剤を容器内に排出して容器の内容物に混合するための混合器に関する。 The present invention relates to a mixer mounted on the cylindrical neck of a container for discharging the contained mixture into the container and mixing it with the contents of the container.

下記特許文献１乃至３には、円筒形状口頸部を有する容器の内容物に混合する混合剤を収容した混合器が開示されている。かような混合器は相互に組み合わされた複数個の構成要素から構成されており、最下方の構成要素を容器の口頸部に装着することによって容器に装着される。そして、構成要素が相対的に移動されることによって、密封された混合剤収容室を規定している部材の一部が破断されて混合剤収容空間の密封が解除され、混合剤収容室に収容されている混合剤が容器内に排出される。 The following Patent Documents 1 to 3 disclose mixers containing a mixing agent to be mixed with the contents of a container having a cylindrical mouth neck. Such a mixer is composed of several components which are combined with one another and is mounted on the container by mounting the lowermost component on the neck of the container. Then, the components are moved relative to one another, whereby a part of the member defining the sealed mixed agent storage chamber is broken to release the seal of the mixed agent storage space, and the member is accommodated in the mixed agent storage chamber. The mixed agent being discharged is discharged into the container.

而して、従来の混合器には、（１）密封された混合剤収容室の底面は加熱融着（一般にヒートシールと称されている）によって混合剤収容室の側面を規定している部材に固着されるシール部材から構成されており、かかるシール部材を破断することによって混合剤収容室の密封が解除されるが、混合剤収容室内に混合剤を充填した後にシール部材を加熱融着する操作は比較的煩雑であり、これに起因して製造工程が比較的煩雑であり製造コストが高価になってしまう、（２）シール部材を破断するための破断手段が配設されている構成要素をシール部材が固着されている構成要素に対して相対的に回転することによってシール部材に対して破断手段を中心軸線方向に相対的に移動せしめてシール手段を破断している、即ち構成要素の回転運動をそのまま利用するのではなくて構成要素の回転運動によって破断手段を相対的に軸線方向に移動せしめることによってシール手段を破談している故に、混合剤収容空間の密封解除を充分迅速に遂行することができない、という問題が存在する。 Thus, in a conventional mixer, (1) a bottom surface of the sealed mixed agent storage chamber defines a side surface of the mixed agent storage chamber by heat fusion (generally referred to as heat seal) The seal of the mixture storage chamber is released by breaking the seal member, but the seal member is heated and fused after the mixture storage chamber is filled with the mixture. The operation is relatively complicated, resulting in relatively complicated manufacturing process and expensive manufacturing cost. (2) Component provided with a breaking means for breaking the seal member By moving the breaking means relative to the seal member in the central axial direction by rotating the seal relative to the component to which the seal member is fixed, ie, breaking the seal means, Rotational motion Since the sealing means is broken by relatively moving the breaking means in the axial direction by the rotational movement of the component rather than using it as it is, sealing release of the mixture containing space can be accomplished quickly enough. There is a problem that it can not.

A new and improved mixing which is able to use the relative rotational movement of the components as it is to unseal the admixture containing space, and thus to unseal the admixture containing space sufficiently quickly. To provide the

次に、主として図１１を参照して、上述したとおりの混合器の使用様式を説明する。最初に、図１１Ａに図示する如く、上側部材６を倒立状態にして適宜の支持基台（図示していない）上に載置する。そして、上側部材６の筒状壁４６によって規定されている混合剤収容室４５内に粉体或いは液体でよい所要混合剤（図示していない）を充填する。次いで、図１１Ｂに図示するとおり、本体４に上側部材６を装着する。更に詳しくは、倒立状態にせしめた本体４を倒立状態で支持されている上側部材６に組み合わせる。この際には、本体４の側壁１２を上側部材６のスカート壁４４内に位置せしめ、上側部材６の筒状壁４６の先端部を本体４の外側密封壁３０と内側密封壁３２との間に進入せしめ、上側部材６のスカート壁４４の下端（図１１Ｂにおいては上端）が本体４の環状フランジ３６に当接するまで、上側部材６に対して本体４を下降せしめる。かくすると、本体４の側壁１２に形成されている係止突条３８が上側部材６のスカート壁４４に形成されている弧状突条４８を弾性的に乗り越えて弧状突条４８が係止手段３８に係止され、上側部材６と本体４とが相互に係止せしめられる。また、上側部材６の筒状壁４６における環状突条５０が形成されている下部（図１１Ｂにおいては上部）の外周面及び内周面に本体４の外側密封壁３０及び内側密封壁３２が夫々密接し、これによって混合剤収容室４５の開放されていた下面（図１１Ｂでは上面）が本体４の閉塞壁１０によって密封される。 Next, the mode of use of the mixer as described above will be described mainly with reference to FIG. First, as shown in FIG. 11A, the upper member 6 is turned upside down and placed on a suitable support base (not shown). Then, the mixture containing chamber 45 defined by the cylindrical wall 46 of the upper member 6 is filled with a required mixture (not shown) which may be powder or liquid. The upper member 6 is then attached to the main body 4 as illustrated in FIG. 11B. More specifically, the inverted main body 4 is combined with the upper member 6 supported in the inverted state. At this time, the side wall 12 of the main body 4 is positioned in the skirt wall 44 of the upper member 6, and the tip of the cylindrical wall 46 of the upper member 6 is between the outer sealing wall 30 and the inner sealing wall 32 of the main body 4. And lower the main body 4 relative to the upper member 6 until the lower end (upper end in FIG. 11B) of the skirt wall 44 of the upper member 6 abuts on the annular flange 36 of the main body 4. Thus, the locking ridge 38 formed on the side wall 12 of the main body 4 elastically rides over the arc-shaped ridge 48 formed on the skirt wall 44 of the upper member 6, and the arc-shaped ridge 48 engages the locking means 38. The upper member 6 and the main body 4 are locked to each other. Further, the outer sealing wall 30 and the inner sealing wall 32 of the main body 4 are respectively provided on the outer peripheral surface and the inner peripheral surface of the lower portion (the upper portion in FIG. 11B) where the annular ridge 50 is formed in the cylindrical wall 46 of the upper member 6. The closed lower surface (upper surface in FIG. 11B) of the mixture storage chamber 45 is sealed by the closed wall 10 of the main body 4 in close contact.

次に、図１に図示するとおり、本体４に下側部材８を回転自在に装着する。更に詳しくは、正立状態で支持基台（図示していない）上に支持されている下側部材８に、上側部材６が装着されている本体４が正立状態で組み合わされる。この際には、本体４の側壁１２を下側部材８の装着壁５２の外側に位置せしめ、本体４の垂下壁２２の下端が下側部材８の支持片５４の上面に当接する位置まで下側部材８に対して本体４を下降せしめる。かくすると、下側部材８の密封壁６６の外周面が本体４の垂下壁２２の内周面に密接される。周方向においては、本体４に形成されている突起２４とラチェット爪２６との間に下側部材８に形成されている係止突起６８を位置せしめる（図５及び図９を参照されたい）。従って、下側部材８の係止突起６８と本体４の突起２４との協働によって、図１において上方から見て時計方向における下側部材８に対する本体４の回転、換言すれば本体２に対する下側部材８の図１において上方から見て反時計方向の回転が阻止される。所望ならば、本体４と下側部材８とを組み合わせる際の周方向位置合わせを確実に遂行するために、例えば本体４の側壁１２の内周面の特定角度位置に突起又は軸線方向に延びる溝を形成すると共に下側部材８の装着壁５２の外周面に軸線方向に延びる溝又は突起を形成し、突起と溝とを噛み合わせることによって本体４と下側部材８との相対的周方向位置を規定するようになすこともできる。本体４に下側部材８を所要とおりに装着した状態において、下側部材８の係止手段６０の各々の弧状部６０ｂは本体４の被係止手段１８の各々の張出梁部１８ｂに対して反時計方向上流側に離間されている（図１２Ａを参照されたい）。 Next, as illustrated in FIG. 1, the lower member 8 is rotatably attached to the main body 4 . More specifically, the lower member 8 supported on a support base (not shown) in the upright state is combined with the main body 4 on which the upper member 6 is mounted in the upright state. At this time, the side wall 12 of the main body 4 is positioned outside the mounting wall 52 of the lower member 8 so that the lower end of the depending wall 22 of the main body 4 abuts on the upper surface of the support piece 54 of the lower member 8. The main body 4 is lowered relative to the side member 8. Thus, the outer peripheral surface of the sealing wall 66 of the lower member 8 is in close contact with the inner peripheral surface of the hanging wall 22 of the main body 4. In the circumferential direction, the locking projection 68 formed on the lower member 8 is positioned between the projection 24 formed on the main body 4 and the ratchet pawl 26 (see FIGS. 5 and 9). Accordingly, the cooperation of the locking projection 68 of the lower member 8 and the projection 24 of the main body 4 causes the rotation of the main body 4 relative to the lower member 8 in the clockwise direction as viewed from above in FIG. When viewed from above in FIG. 1, the side member 8 is prevented from rotating counterclockwise. If desired, for example, a projection or an axially extending groove at a specific angular position on the inner peripheral surface of the side wall 12 of the main body 4 in order to ensure circumferential alignment when combining the main body 4 and the lower member 8 While forming an axially extending groove or protrusion on the outer peripheral surface of the mounting wall 52 of the lower member 8 and engaging the protrusion with the groove, the relative circumferential position between the main body 4 and the lower member 8 It can also be done to define When the lower member 8 is mounted on the main body 4 as required, the arc-shaped portions 60 b of the locking means 60 of the lower member 8 with respect to the overhanging beam portions 18 b of the locking means 18 of the main body 4 Counterclockwise upstream (see FIG. 12A).

上述したとおりにして完成され混合剤を収容した混合器２は、それ単独で市場に流通する或いは容器の円筒形状口頸部に蓋として装着した状態で市場に流通することができる。混合器２がそれ自体単独で市場に流通される場合には、消費者は、混合器２の下側部材８を適用することができる口頸部を有する容器と組み合わせて混合器２を使用する。図１には、ポリエチレンテレフタレートの如き適宜の合成樹脂、アルミニウム基合金薄板の如き金属薄板或いはガラスから形成することができる容器の口頸部７８も二点鎖線で図示されている。この口頸部７８は全体として円筒形状であり、その外周面には雄螺条８０とこの雄螺条８０の下方に位置する環状フランジ８２が形成されている。容器内には天然水の如き液体（図示していない）が収容されており、口頸部７８にはタンパーエビデント裾部８４を備えたそれ自体は周知の形態の容器蓋（図１にはタンパーエビデント裾部８４のみを二点鎖線で図示している）が装着されている。 The mixer 2 complete | finished as mentioned above and containing the mixing agent can distribute | circulate to the market in the state which distribute | circulates to the market independently, and it equips with the cylindrical-shaped opening neck of a container as a lid | cover. If the mixer 2 is distributed to the market by itself, the consumer uses the mixer 2 in combination with a container having a mouth and neck to which the lower member 8 of the mixer 2 can be applied. . Also shown in FIG. 1 is a mouth and neck 78 of a container which can be made of a suitable synthetic resin such as polyethylene terephthalate, a thin metal plate such as an aluminum-based alloy thin plate or glass. The mouth and neck portion 78 has a cylindrical shape as a whole, and a male screw 80 and an annular flange 82 located below the male screw 80 are formed on the outer peripheral surface thereof. The container contains a liquid (not shown) such as natural water, and the mouth and neck portion 78 is provided with a tamper evident skirt 84 and is a container lid of a well-known form (see FIG. 1). Only the tamper-evident foot 84 is shown by a two-dot chain line).

図１を参照して説明を続けると、上記容器内に混合器２に収容されている混合剤を排出して容器の内容物に混合剤を混入する際には、容器の口頸部７８に装着されている容器蓋本体を離脱して口頸部７８を開封する。容器蓋のタンパーエビデント裾部８４は容器蓋本体から分離されて口頸部７８の環状フランジ８２上に残留する。しかる後に、口頸部７８に混合器２を被嵌し、例えば本体４の側壁１２の下部外周面に指を掛けて本体４を閉方向（上方から見て時計方向）に回転せしめる。かくすると、上述した如く本体４の突起２４と下側部材８の係止突起６８との協働によって本体４に対して下側部材８が相対的に時計方向に回転することが防止される故に、本体４の時計方向の回転に付随して下側部材８も時計方向に回転せしめられる。上側部材６は本体４に比較的緊密に装着されている故に、上側部材６も本体の時計方向の回転に付随して時計方向に回転せしめられる。下側部材８の時計方向への回転に従って下側部材８の雌螺条７６が口頸部７８の雄螺条８０に漸次螺合され、下側部材８は時計方向への回転と共に口頸部７８に対して相対的に下降される。口頸部７８に対して下側部材８が図１に図示する位置まで下降せしめられると、口頸部７８の上端部が下側部材８の内側密封突条７０と外側密封突条７２との間に進入し、内側密封部材７０の外周面が口頸部７８の内周面に密接されると共に外側密封部材７２の内周面が口頸部７８の外周面に密接され、これによって口頸部７８が密封される。 To continue the description with reference to FIG. 1, when discharging the mixing agent contained in the mixer 2 in the above container and mixing the mixing agent into the contents of the container, The attached container lid main body is removed and the mouth and neck 78 is opened. The tamper-evident skirt 84 of the container lid is separated from the container lid body and remains on the annular flange 82 of the neck and neck 78. Thereafter, the mixer 2 is fitted on the mouth and neck portion 78, and for example, a finger is put on the lower outer peripheral surface of the side wall 12 of the main body 4 to rotate the main body 4 in the closing direction (clockwise as viewed from above). Thus, as described above, the cooperation between the projection 24 of the main body 4 and the locking projection 68 of the lower member 8 prevents the lower member 8 from rotating relative to the main body 4 in the clockwise direction. The lower member 8 is also rotated clockwise as the main body 4 rotates clockwise. Because the upper member 6 is mounted relatively tightly to the body 4, the upper member 6 is also rotated clockwise with the clockwise rotation of the body. In accordance with the clockwise rotation of the lower member 8, the female screw 76 of the lower member 8 is gradually screwed on the male screw 80 of the mouth neck 78, and the lower member 8 is rotated clockwise. It is lowered relative to 78. When the lower member 8 is lowered to the position shown in FIG. 1 with respect to the mouth and neck 78, the upper end of the mouth and neck 78 is the seal between the inner sealing ridge 70 and the outer sealing ridge 72 of the lower member 8. The outer peripheral surface of the inner sealing member 70 is brought into close contact with the inner peripheral surface of the mouth neck 78 and the inner peripheral surface of the outer sealing member 72 is brought into close contact with the outer peripheral surface of the mouth neck 78. The part 78 is sealed.

次いで、例えば本体４の側壁１２の下部外周面に指を掛けて反時計方向に回転する。下側部材８はその雌螺条７６が口頸部７８の雌螺条８０に充分緊密に螺合せしめられている故に上方から見て反時計方向（図１２においては時計方向）への回転が阻止され、従って本体４は下側部材８に対して反時計方向に回転せしめられる。下側部材８に対して本体４が反時計方向に所定角度α回転されると、下側部材８に形成されている係止手段６０の各々が本体４の被係止手段１８の各々に係止せしめられる。更に詳しくは、図１２Ｂに図示する如く、係止手段６０の各々の弧状部６０ｂが被係止手段１８の各々の張出梁部１８ｂの上方に進入し、係止手段６０の各々の柱部６０ａが被係止手段１８の各々の張出梁部１８ｂに当接せしめられる。上記所定角度αは５０乃至６０度程度であるのが好都合である。下側部材８に対して本体４が上記所定角度αを超えて更に反時計方向に回転せしめられると、被係止手段１８を介して破断可能薄肉ライン１４の各々に応力が加えられ、図１２ｃに図示する如く、被係止手段１８の回転に伴って破断可能薄肉ライン１４の各々が破断開始端部１４ａから破断され始める。下側部材８に対して本体４が上記所定角度αよりも０乃至２０度程度大きい角度だけ回転せしめられると、本体４のラチェット爪２６が下側部材８の係止突起６８を弾性的に乗り越え、従ってラチェット爪２６の切り立った係止面と係止突起６８との協働によって本体４が下側部材８に対して時計方向に戻り回転することが阻止される。 Then, for example, a finger is placed on the lower outer peripheral surface of the side wall 12 of the main body 4 to rotate in the counterclockwise direction. The lower member 8 has its female screw 76 screwed sufficiently tightly to the female screw 80 of the neck and neck portion 78 so that it can be rotated counterclockwise as viewed from above (clockwise in FIG. 12). It is blocked and thus the body 4 is rotated counterclockwise relative to the lower member 8. When the main body 4 is rotated counterclockwise by the predetermined angle α with respect to the lower member 8, each of the locking means 60 formed on the lower member 8 is engaged with each of the locked means 18 of the main body 4 It is stopped. More specifically, as shown in FIG. 12B, the arcs 60b of the locking means 60 enter above the overhanging beams 18b of the locking means 18 and the columns of the locking means 60. 60a is brought into contact with each overhanging beam portion 18b of the locked means 18; The predetermined angle α is conveniently about 50 to 60 degrees. When the main body 4 is further rotated counterclockwise with respect to the lower member 8 beyond the predetermined angle α, stress is applied to each of the breakable thin-walled lines 14 via the locking means 18, as shown in FIG. As shown in FIG. 2, with rotation of the locking means 18, each of the frangible thin-walled lines 14 begins to be broken from the break start end 14a. When the main body 4 is rotated relative to the lower member 8 by about 0 to 20 degrees larger than the predetermined angle α, the ratchet claw 26 of the main body 4 elastically rides over the locking projection 68 of the lower member 8 Thus, the cooperation of the sharp locking surfaces of the ratchet pawls 26 and the locking projections 68 prevents the body 4 from rotating back relative to the lower member 8 in a clockwise direction.

図１２Ｃ及び図１２Ｄを参照することによって明確に理解されるとおり、上記所定角度αを超えて本体４が反時計方向に回転されるに従って、破断可能薄肉ライン１４の破断開始端１４ａに続いて外側弧状部１４ｂ及び内側弧状部１４ｃの破断が漸次進行、従って開口が漸次進行する。変形領域１６における反時計方向下流半部（時計方向上流半部）は反時計方向下流に向かって漸次下方に傾斜している故に、外側弧状部１４ｂ及び内側弧状部１４ｃには軸線方向下方への引っ張り力も加えられ、そしてまた変形領域１６の既に変形された部位が重なり合うことが可及的に回避され、かくして破断可能薄肉ライン１４の破断及び変形領域１６の変形が充分容易に進行せしめられる。本体４の反時計方向への回転が更に進行すると、本体４のラチェット爪２８も下側部材８の係止突起６８を弾性的に乗り越える。従って、ラチェット爪２８と係止突起６８との協働によって、下側部材８に対して本体４が時計方向に戻り回転することが阻止される。そして更に本体４が下側部材８に対して反時計方向に回転せしめられ、下側部材８に対する本体４の回転角度がβに至ると、本体４の突起２４が下側部材８の係止突起６８に当接し、下側部材８に対して本体４が更に反時計方向に回転することが阻止される。かかる時点においては外側可能薄肉ライン１４の破断は外側弧状部１４ｂ及び内側弧状部１４ｃの実質上終端迄進行し、変形領域１６は下方及び時計方向に変形されてロール状にせしめられ、閉塞壁１０には２個の通過開口が形成される。混合器２の混合剤収容室４５内に収容されていた混合剤（図示していない）は、変形領域１６の上述したとおりの変形に応じて生成され拡張される通過開口を通って、そしてまた下側部材８に形成されている通過開口５８を通って下方に流動し、容器内に排出され手容器の内容物に混入せしめられる。 As is clearly understood by reference to FIGS. 12C and 12D, as the main body 4 is rotated counterclockwise beyond the predetermined angle α, the outer side following the break start end 14a of the thin line 14 which can be broken is The breaking of the arcs 14b and the inner arcs 14c is progressive and thus the opening is progressive. Since the counterclockwise downstream half (the clockwise upstream half) in the deformation region 16 is inclined downward gradually toward the counterclockwise downstream side, the outer arc-shaped portion 14 b and the inner arc-shaped portion 14 c are axially lowered in the axial direction. Tension is also applied, and also overlapping of the already deformed parts of the deformation area 16 is avoided as much as possible, so that the fracture of the frangible thin-walled line 14 and the deformation of the deformation area 16 are easily facilitated. When the counterclockwise rotation of the main body 4 further progresses, the ratchet claws 28 of the main body 4 elastically ride over the locking projections 68 of the lower member 8 as well. Thus, the cooperation of the ratchet pawl 28 and the locking projection 68 prevents the main body 4 from rotating clockwise relative to the lower member 8 and rotating. When the main body 4 is further rotated counterclockwise with respect to the lower member 8 and the rotation angle of the main body 4 with respect to the lower member 8 reaches β, the projection 24 of the main body 4 is a locking projection of the lower member 8 It abuts 68 and is prevented from further counterclockwise rotation of the body 4 relative to the lower member 8. At this point, the fracture of the outer thin line 14 proceeds substantially to the end of the outer arc 14b and the inner arc 14c, and the deformation area 16 is deformed downward and clockwise into a roll, closing the closure wall 10 There are two passage openings formed in. The mixing agent (not shown) contained in the mixing agent storage chamber 45 of the mixing device 2 passes through the passage openings which are generated and expanded in response to the above-described deformation of the deformation area 16 and also It flows downward through the passage opening 58 formed in the lower member 8, is discharged into the container and is mixed with the contents of the hand container.

混合剤が容器内に排出された後においては、必要に応じて混合器２が装着されたままの容器を適宜に振動せしめて容器の内容物と混合剤の混合を促進する。次いで、例えば本体４の側壁１２の下部に指を掛けて本体２を反時計方向に回転する。上述したとおり下側部材８に対して本体４が反時計方向に上記回転角度β迄回転されると、本体４の突起２４と下側部材８の係止突起６８との協働によって下側部材８に対して本体４が反時計方向に回転することが阻止され、従って本体４の反時計方向への回転に応じて下側部材８も反時計方向に回転される。本体４の反時計方向への回転に付随して下側部材８が反時計方向に回転されると、口頸部７８の雄螺条８２に対する下側部材８の雌螺条７６の螺合が漸次解除され、混合器２の全体が口頸部７８から離脱されて口頸部７８が開封され、かくして混合剤が混入された容器の内容物を消費することができる。 After the mixing agent is discharged into the container, the container with the mixer 2 attached thereto is vibrated as appropriate to promote mixing of the contents of the container and the mixing agent. Then, for example, a finger is put on the lower part of the side wall 12 of the main body 4 to rotate the main body 2 in the counterclockwise direction. As described above, when the main body 4 is rotated in the counterclockwise direction with respect to the lower member 8 by the rotation angle β, the lower member is cooperated with the projection 24 of the main body 4 and the locking projection 68 of the lower member 8. The rotation of the body 4 in the counterclockwise direction relative to 8 is prevented, so that in response to the rotation of the body 4 in the counterclockwise direction, the lower member 8 is also rotated in the counterclockwise direction. When the lower member 8 is rotated in the counterclockwise direction accompanying the counterclockwise rotation of the main body 4, screwing of the female screw 76 of the lower member 8 with respect to the male screw 82 of the neck and neck 78 Gradually released, the entire mixer 2 is removed from the neck portion 78, the neck portion 78 is opened, and the contents of the container mixed with the mixture can be consumed.
