That is, the screw mechanism 30 includes a thread 31 provided on the outer peripheral surface of the first mouth tube portion 2 of the inner container 1 and a thread 32 provided on the inner surface of the inner cylinder wall 14 of the outer cover 10. The outer cover 10 can be firmly armored on the inner container 1 by screwing them together.

図１及び図４に示すように、内容器１に外カバー１０を外装した状態では、注出ノズル８が第２口筒部１２内に配置されると共に、注出ノズル８の先端８Ａは第２口筒部１２の上端１２Ａに形成された開口部１２ａを介してさらに上方に突出する状態に設定される。   As shown in FIGS. 1 and 4, in a state where the outer cover 10 is packaged on the inner container 1, the pouring nozzle 8 is disposed in the second mouth tube portion 12, and the tip 8 </ b> A of the pouring nozzle 8 is the first one. The state is set so as to protrude further upward through an opening 12 a formed at the upper end 12 </ b> A of the two-port cylinder portion 12.

また、内筒壁１４の内面と第１口筒部２の外面とが対向する部分で且つネジ機構３０の下部位置にはストッパ機構３５が設けられている。ストッパ機構３５は、例えば図５に示すように、第１口筒部２の外面で且つ螺条３１の下部位置に突出形成された係合凸部３５ａと、内筒壁１４の内面で且つ螺条３２の下部位置に周方向に所定の間隔を置いて形成された一対の突起３５ｂとにより構成される。この実施例では、係合凸部３５ａは外カバー１０を螺合して外装する際に、回転上流側Ｕとなる一端に緩やかな傾斜面を有し、回転下流側ｄの他端に垂直面を有して構成されている。一対の突起３５ｂは、回転上流側Ｕに設けられた乗越え突起３５ｂ１と回転下流側ｄに設けられた規制突起３５ｂ２とにより構成される。乗越え突起３５ｂ１は回転上流側Ｕとなる一端に緩やかな傾斜面を有し、他端に垂直面を有する突起として構成され、規制突起３５ｂ２は少なくとも回転上流側Ｕとなる一端を垂直面で形成した突起として構成される。   A stopper mechanism 35 is provided at a position where the inner surface of the inner cylindrical wall 14 and the outer surface of the first mouth tube portion 2 face each other and at a lower position of the screw mechanism 30. For example, as shown in FIG. 5, the stopper mechanism 35 includes an engagement convex portion 35 a that is formed to project from the outer surface of the first mouth tube portion 2 and the lower position of the screw 31, the inner surface of the inner tube wall 14, and a screw. It comprises a pair of protrusions 35b formed at predetermined positions in the circumferential direction at the lower position of the strip 32. In this embodiment, when the outer cover 10 is screwed and sheathed, the engaging convex portion 35a has a gently inclined surface at one end that becomes the upstream side U of rotation, and a vertical surface at the other end of the downstream side d of rotation. It is comprised. The pair of protrusions 35b includes a ride-over protrusion 35b1 provided on the rotation upstream side U and a restriction protrusion 35b2 provided on the rotation downstream side d. The ride-over protrusion 35b1 is configured as a protrusion having a gentle inclined surface at one end which becomes the upstream side U of rotation and a vertical surface at the other end, and the restriction protrusion 35b2 is formed with at least one end which becomes the upstream side U of rotation as a vertical surface. Configured as a protrusion.

図１及図２に示すように、キャップ２０は、下面中央に有頂筒状の収納凹部２１が設けられており、収納凹部２１の頂壁２１ａの下面にはパッキン２２が固着されている。図１に示すように、内容器１に外カバー１０を外装した状態においては、収納凹部２１内に、第２口筒部１２とその上端１２Ａから突出した注出ノズル８の先端８Ａとを一緒に収納することが可能となっている。   As shown in FIG. 1 and FIG. 2, the cap 20 is provided with a cylindrical storage recess 21 at the center of the lower surface, and a packing 22 is fixed to the lower surface of the top wall 21 a of the storage recess 21. As shown in FIG. 1, in a state where the outer cover 10 is externally mounted on the inner container 1, the second mouth tube portion 12 and the tip 8 </ b> A of the dispensing nozzle 8 protruding from the upper end 12 </ b> A are put together in the storage recess 21. It is possible to store in.

また収納凹部２１の内周面と第２口筒部１２の外周面にはネジ機構が設けられており、収納凹部２１の内周面に形成された螺条と第２口筒部１２の外周面に刻設された螺条とが螺合することにより、外カバー１０の第２口筒部１２をキャップ２０によって被嵌することが可能となっている。   In addition, a screw mechanism is provided on the inner peripheral surface of the storage recess 21 and the outer peripheral surface of the second mouth tube portion 12, and the screw formed on the inner periphery surface of the storage recess 21 and the outer periphery of the second mouth tube portion 12. The second mouth tube portion 12 of the outer cover 10 can be fitted by the cap 20 by being screwed with the screw engraved on the surface.

なお、シール材４０を剥がした状態の注出ノズル８をキャップ２０で被嵌すると、キャップ２０内のパッキン２２が注出ノズル８の先端８Ａに圧接して注出孔８ａに密着するため、内容器１を液密状態に保持することが可能である。   In addition, when the extraction nozzle 8 with the sealing material 40 peeled off is fitted with the cap 20, the packing 22 in the cap 20 comes into pressure contact with the tip 8A of the extraction nozzle 8 and closely contacts the extraction hole 8a. It is possible to keep the vessel 1 in a liquid-tight state.

内容器１に収納された内容液を使い切った際には、内容液が充填されている新たな内容器に交換して使用することになるが、この交換作業は、片手で外カバー１０の外装筒１１を掴持し、もう一方の手で外装筒１１の下端１５から下方に露出している内容器１の露出部７（本実施例では、外装筒１１の下端１５の外周面より横方向に膨出する拡径部７ａとしている。）を掴持して、両者を相対的に回転させることにより、大きな回転トルクを発生させることが可能となる。そして、この回転トルクを利用することにより、内容器１を外カバー１０から容易に取り外すことができ、また新たな内容器１を外カバー１０内に取り付けることができる。すなわち、内容器１を容易に交換することが可能となっている。   When the content liquid stored in the inner container 1 is used up, it is used after being replaced with a new inner container filled with the content liquid. The exposed portion 7 of the inner container 1 that grips the tube 11 and is exposed downward from the lower end 15 of the outer tube 11 with the other hand (in this embodiment, lateral direction from the outer peripheral surface of the lower end 15 of the outer tube 11) It is possible to generate a large rotational torque by grasping the diameter-expanded portion 7a that swells and rotating the two relative to each other. By using this rotational torque, the inner container 1 can be easily detached from the outer cover 10, and a new inner container 1 can be attached in the outer cover 10. That is, the inner container 1 can be easily replaced.

また新たな内容器１に外カバー１０を外装する際には、両者を相対的に回転させたときに、内容器１側の第１口筒部２に設けられた係合凸部３５ａが、外カバー１０側の内筒壁１４に形成された一対の突起３５ｂのうち、最初に回転上流側Ｕに位置する一方の乗越え突起３５ｂ１を相対的に乗り越え、次に回転下流側ｄに位置する他方の規制突起３５ｂ２に当接して回転が停止させられる。係合凸部３５ａが乗越え突起３５ｂ１を乗り越える際には回転負荷が増して回転トルクが重く感じると共に、乗り越えると同時に「カッチ」という音が発生する。このため、作業者に外カバー１０の外装作業が完了したことを触覚及び聴覚を通じてらしめることが可能となる。   Further, when the outer cover 10 is externally mounted on the new inner container 1, when the two are relatively rotated, the engagement convex portion 35a provided on the first mouth tube portion 2 on the inner container 1 side is Of the pair of projections 35b formed on the inner cylinder wall 14 on the outer cover 10 side, the first overpass projection 35b1 positioned on the upstream side U of the rotation is first overcome, and then the other side positioned on the downstream side d of the rotation. The rotation is stopped by abutting against the regulating projection 35b2. When the engagement convex portion 35a gets over the ride-over protrusion 35b1, the rotational load increases and the rotational torque feels heavy, and at the same time it gets over, the sound of “catch” is generated. For this reason, it becomes possible to let an operator know through the touch and hearing that the exterior work of the outer cover 10 has been completed.

上記の外装作業は、キャップ２０を外カバー１０に装着した状態で行うこともできるし、またキャップ２０を外した状態で行うことも可能である。   The exterior work described above can be performed with the cap 20 attached to the outer cover 10 or can be performed with the cap 20 removed.

そして、外カバー１０の外装作業が完了すると、内容器１側の注出ノズル８の先端８Ａが第２口筒部１２の上端１２Ａから突出する状態となる。キャップ２０を外カバー１０に装着した状態で外装作業を行った場合にはキャップ２０を外してから、またキャップ２０を外した状態で外装作業を行った場合にはその状態から、シール材４０を剥がすことにより内容液の注出が可能となる。   When the exterior work of the outer cover 10 is completed, the tip 8A of the pouring nozzle 8 on the inner container 1 side is in a state of protruding from the upper end 12A of the second mouth tube portion 12. When the exterior work is performed with the cap 20 attached to the outer cover 10, the cap 20 is removed, and when the exterior work is performed with the cap 20 removed, the sealing material 40 is removed from that state. The content liquid can be poured out by peeling.

このように、本発明では、内容器１に外カバー１０を外装した後に、注出ノズル８の先端８Ａを封止するシール材４０を剥がして注出孔８ａを表出させることができるため、外装作業前や作業中の操作ミス等により誤って内容器１を転倒させたとしても内容液の零れを確実に防止することが可能である。   Thus, in the present invention, after the outer cover 10 is sheathed on the inner container 1, the sealing material 40 that seals the tip 8A of the dispensing nozzle 8 can be peeled off to expose the dispensing hole 8a. Even if the inner container 1 is accidentally overturned by an operation mistake or the like before the exterior work, it is possible to reliably prevent the liquid content from spilling.

また外装カバー１０及びキャップ２０は繰り返し使用されるが、内容器１は注出ノズル８と一緒に交換されるため、常に新しい注出ノズル８を用いての内容液の注出が可能となる。よって、衛生面において優れた注出容器ＰＢとすることができる。   Although the outer cover 10 and the cap 20 are repeatedly used, the inner container 1 is exchanged together with the pouring nozzle 8, so that the content liquid can always be poured using the new pouring nozzle 8. Therefore, it can be set as the extraction container PB excellent in hygiene.

なお、外装筒１１は第１口筒部２から十分離れた位置にあるので、内容液の付着による滑りの発生を無くすことができる。また、外装筒１１により、内容器１の大半部分を外装するようにしているので、この外装筒１１を印刷やラベルにより加飾しておくことにより、注出容器ＰＢとしての加飾性は十分発揮され、内容器１の加飾は省略することができる。   In addition, since the exterior cylinder 11 is located at a position sufficiently away from the first mouth tube portion 2, it is possible to eliminate the occurrence of slippage due to the adhesion of the content liquid. In addition, since the outer cylinder 11 covers most of the inner container 1, decorating the outer cylinder 11 with printing or labels provides sufficient decorating properties as the dispensing container PB. As a result, the decoration of the inner container 1 can be omitted.

また、本実施例では外装筒１１の下端１５が周段部６に近接又は当接するように構成しており、外装筒１１の外周面と内容器１の拡径部７ａの外周面の繋がりをスムーズにして、良好な外観が得られるようにしている。また、内容器１は透明又は半透明性であり露出部７から内容液の残量を視覚的に確認することが可能であり、安心して使用することができる。   Further, in this embodiment, the lower end 15 of the outer cylinder 11 is configured to approach or abut on the circumferential step portion 6, and the connection between the outer peripheral surface of the outer cylinder 11 and the outer peripheral surface of the enlarged diameter portion 7 a of the inner container 1 is established. It is smooth so that a good appearance can be obtained. Further, the inner container 1 is transparent or translucent, and the remaining amount of the content liquid can be visually confirmed from the exposed portion 7, and can be used with confidence.

以上、実施例に沿って本発明の構成とその作用効果について説明したが、本発明の実施の形態は上記実施例に限定されるものではない。   As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.

The configuration provided on the cylindrical wall 14 side has been shown and described. However, as shown in FIG. 6, the engaging convex portion 35 a is provided on the inner cylindrical wall 14 side of the outer cover 10, and the pair of protrusions 35 b are provided on the first side of the inner container 1. It can also be set as the structure provided in the mouth tube part 2 side.

また上記実施例では、内容器１を透明又は半透明な合成樹脂で形成し、外カバー１０を不透明な樹脂で形成し、外装筒１１の表面に胴部４に印刷やラベルにより加飾する構成を示して説明したが、本発明は上記実施例に限定されるものではなく、例えば外カバー１０を透明又は半透明な合成樹脂で形成し、内容器１を不透明な樹脂で形成すると共に内容器１の胴部４に印刷やラベルにより加飾することにより、透明又は半透明の外カバー１０を通して内側の内容器１に加飾された印刷やラベルが視認可能な構成とすることもできる。さらには内容器１と外カバー１０を共に透明又は半透明な合成樹脂で形成してもよいし、あるいは共に不透明な合成樹脂で形成してもよい。   In the above embodiment, the inner container 1 is formed of a transparent or translucent synthetic resin, the outer cover 10 is formed of an opaque resin, and the body 4 is decorated on the surface of the outer cylinder 11 by printing or labeling. However, the present invention is not limited to the above embodiment. For example, the outer cover 10 is formed of a transparent or translucent synthetic resin, the inner container 1 is formed of an opaque resin, and the inner container is formed. It can also be set as the structure which can visually recognize the printing and the label which were decorated by the inner container 1 through the transparent or translucent outer cover 10 by decorating the 1 trunk | drum 4 with printing or a label. Furthermore, both the inner container 1 and the outer cover 10 may be formed of a transparent or translucent synthetic resin, or both may be formed of an opaque synthetic resin.

また例えば上記実施例では外装筒１１を内容器１の底部５近傍にまで垂下しているが、内容器の交換に伴なう操作性や、外観や、部材コスト等を考慮して胴部４の中央高さ位置までにする等、適宜選択することができる。 Further, for example, in the above-described embodiment, the outer casing 11 is suspended to the vicinity of the bottom 5 of the inner container 1, but the barrel 4 is considered in consideration of operability, appearance, member cost, etc. associated with the replacement of the inner container. It is possible to appropriately select the center height position.

また、内容器１としてはポリエチレンテレフタレート製に限定されることなく各種合成樹脂製のものを目的に応じて使用することができる。   In addition, the inner container 1 is not limited to polyethylene terephthalate but can be made of various synthetic resins depending on the purpose.

本発明の注出容器は、簡便に内容器を交換することができ、また交換作業前及び作業中の内容器の転倒による零れ防止や作業の完了を容易に知ることができるものであり、レフィルタイプの注出容器として幅広い用途展開が期待される。   The dispensing container according to the present invention can easily replace the inner container, and can easily prevent spilling due to the overturning of the inner container before and during the replacement work, and can easily know the completion of the work.
