付勢部材６は、内筒ねじ結合部１４において下方に螺脱した内筒４を上方に付勢するとともに内筒ねじ結合部１４において上方に螺脱した内筒４を下方に付勢するように構成されている。したがって、操作部２０に対する繰出し方向の回転操作によって螺脱した内筒ねじ結合部１４を、操作部２０に対する引込み方向の回転操作がされたときに、付勢部材６の付勢力によって容易に螺合させることができるとともに、操作部２０に対する引込み方向の回転操作によって螺脱した内筒ねじ結合部１４を、操作部２０に対する繰出し方向の回転操作がされたときに、付勢部材６の付勢力によって容易に螺合させることができる。なお、付勢部材６は、このような構成に限らず、例えば、内筒ねじ結合部１４において下方に螺脱した内筒４には係合して内筒４を上方に付勢するが、内筒ねじ結合部１４において上方に螺脱した内筒４とは係合しない構成としても構わない。このような構成とした場合には、操作部２０に対する引込み方向の回転操作によって螺脱した内筒ねじ結合部１４を、操作部２０に対する繰出し方向の回転操作がされたときに、内筒４を下降させる重力によって螺合させることができる。また、付勢部材６は、内筒ねじ結合部１４において上方に螺脱した内筒４を下方に付勢するときの状態において、付勢部材６の外周面における上下方向に亘る部分全体が、外筒２の拡径内周面２ｃに沿うように配置されている。 The biasing member 6 urges upward the inner cylinder 4 unscrewed downward at the inner cylinder screw joint 14 and downwardly urges the inner cylinder 4 unscrewed upward at the inner cylinder screw joint 14 . is configured to Therefore, when the operating portion 20 is rotated in the retracting direction, the inner cylinder screw coupling portion 14, which has been unscrewed by the rotating operation in the extending direction with respect to the operating portion 20, can be easily screwed together by the biasing force of the biasing member 6. In addition, when the operating portion 20 is rotated in the extension direction, the inner cylinder screw coupling portion 14, which has been unscrewed by the rotating operation in the retracting direction with respect to the operating portion 20, is rotated by the biasing force of the biasing member 6. Can be easily screwed together. The urging member 6 is not limited to such a configuration, and for example, engages with the inner cylinder 4 that is screwed off downward at the inner cylinder threaded connection portion 14 to urge the inner cylinder 4 upward. The inner cylinder threaded connection portion 14 may be configured so as not to be engaged with the inner cylinder 4 that is screwed out upward. With such a configuration, the inner cylinder threaded connection portion 14, which is unscrewed by the operation of rotating the operating portion 20 in the retracting direction, is pulled out when the operating portion 20 is rotated in the direction of extension. It can be screwed together by downward gravity. In addition, when the biasing member 6 is in a state of downwardly biasing the inner cylinder 4 unscrewed upward at the inner cylinder screw connection portion 14, the entire vertical portion of the outer peripheral surface of the biasing member 6 is It is arranged along the expanded diameter inner peripheral surface 2 c of the outer cylinder 2 .

図１に示すように、キャップ８は有頂円筒状をなしており、外筒２の縮径部２ａに取外し可能に取付けられることで、固形内容物７及び内筒４を覆っている。 As shown in FIG. 1, the cap 8 has a capped cylindrical shape and is detachably attached to the reduced diameter portion 2a of the outer cylinder 2 to cover the solid content 7 and the inner cylinder 4. As shown in FIG.

外筒２、操作部材９、作動部材１０、内筒４、中皿１１、軸部材１２、付勢部材６及びキャップ８はそれぞれ、合成樹脂製であるが、これに限らず種々の材質を採用可能である。 The outer cylinder 2, the operating member 9, the operating member 10, the inner cylinder 4, the inner plate 11, the shaft member 12, the biasing member 6, and the cap 8 are each made of synthetic resin, but not limited to this, various materials can be used. It is possible.

上記のように構成された繰出し容器１は、例えば次のように使用することができる。使用に際し、使用者はまず、図１に示す使用前の状態からキャップ８を取外す。そして、使用者が図７に示すように回転部３の操作部２０を繰出し方向に回転操作すると、まず、内筒ねじ結合部１４と内筒案内部１３を介して内筒４が外筒２に対して下降するとともに、保持部ねじ結合部１６と保持部案内部１５を介して保持部５が外筒２に対して上昇する。この内筒４の下降と保持部５の上昇により、固形内容物７を内筒４の内部から少ない回転操作で繰出すことができる。そして、繰出し方向の回転操作を続けると、図８に示すように、内筒４が内筒ねじ結合部１４において下方に螺脱して空回りすることで外筒２に対する内筒４の下降が止まる一方、保持部５は保持部ねじ結合部１６において螺合が維持されることで外筒２に対して上昇し続ける。このように、内筒４の下降が止まった状態で保持部５が上昇することにより、固形内容物７の繰出し量を細かく調整することができる。 The delivery container 1 configured as described above can be used, for example, as follows. For use, the user first removes the cap 8 from the pre-use state shown in FIG. When the user rotates the operating portion 20 of the rotating portion 3 in the extension direction as shown in FIG. , and the holding portion 5 rises relative to the outer cylinder 2 via the holding portion screw coupling portion 16 and the holding portion guide portion 15 . By lowering the inner cylinder 4 and raising the holding portion 5, the solid content 7 can be delivered from the inner cylinder 4 with a small rotational operation. When the rotating operation in the delivery direction is continued, as shown in FIG. 8, the inner cylinder 4 is unscrewed downward at the inner cylinder threaded connection portion 14 and idly rotated, thereby stopping the descent of the inner cylinder 4 with respect to the outer cylinder 2. , the holding portion 5 continues to rise with respect to the outer cylinder 2 by maintaining screw engagement at the holding portion threaded joint portion 16 . In this way, by raising the holding portion 5 while the descent of the inner cylinder 4 is stopped, the delivery amount of the solid content 7 can be finely adjusted.

また、固形内容物７を繰出し、固形内容物７を使用、すなわち塗布対象物に塗布した後は、回転部３の操作部２０を引込み方向に回転操作することで、図９に示すように、付勢部材６の付勢力によって内筒ねじ結合部１４が再び螺合する。そして、引込方向の回転操作を続けることで、内筒ねじ結合部１４と内筒案内部１３を介して内筒４が外筒２に対して上昇するとともに、保持部ねじ結合部１６と保持部案内部１５を介して保持部５が外筒２に対して下降する。この内筒４の上昇と保持部５の下降により、固形内容物７を内筒４の内部に向けて少ない回転操作で引込むことができる。そして、さらに引込方向の回転操作を続けると、図１０に示すように、内筒４が内筒ねじ結合部１４において上方に螺脱して空回りすることで外筒２に対する内筒４の上昇が止まる一方、保持部５は保持部ねじ結合部１６において螺合が維持されることで外筒２に対して下降し続ける。 Further, after the solid content 7 is delivered and the solid content 7 is used, that is, after being applied to the object to be coated, the operating portion 20 of the rotating portion 3 is rotated in the retracting direction, as shown in FIG. The urging force of the urging member 6 causes the inner cylinder screw coupling portion 14 to be screwed again. Then, by continuing the rotation operation in the retraction direction, the inner cylinder 4 rises with respect to the outer cylinder 2 via the inner cylinder screw joint 14 and the inner cylinder guide part 13, and the holding part screw joint 16 and the holding part The holding portion 5 descends with respect to the outer cylinder 2 via the guide portion 15 . By raising the inner cylinder 4 and lowering the holding portion 5, the solid content 7 can be pulled into the inner cylinder 4 with a small amount of rotation. 10, the inner cylinder 4 is screwed upward and disengaged from the inner cylinder threaded connection portion 14 and idly rotates, thereby stopping the upward movement of the inner cylinder 4 with respect to the outer cylinder 2. On the other hand, the holding portion 5 continues to descend with respect to the outer cylinder 2 by maintaining screw engagement at the holding portion threaded joint portion 16 .

したがって、繰出し容器１によれば、使用前後の回転操作量を抑えつつ繰出し量を細かく調整することができる。特に、本実施の形態では、内筒ねじ結合部１４のリードが保持部ねじ結合部１６のリードよりも大きく構成されているので、所定の回転操作量に対する内筒４の移動量を保持部５の移動量よりも大きくすることができるため、より効果的に、使用前後の回転操作量を抑えつつ繰出し量を細かく調整することができる。 Therefore, according to the feeding container 1, it is possible to finely adjust the feeding amount while suppressing the rotational operation amount before and after use. In particular, in the present embodiment, the lead of the threaded connection portion 14 of the inner cylinder is larger than the lead of the threaded connection portion 16 of the holding portion. Therefore, it is possible to finely adjust the extension amount while suppressing the rotational operation amount before and after use more effectively.
