According to this configuration, since the sliding contact portion 100 is interposed between the sleeve 11 and the fixed shaft member 23a, an appropriate frictional resistance is applied between the sleeve 11 and the fixed shaft member 23a by the sliding contact portion 100. be able to. As a result, rattling between the sleeve 11 and the fixed shaft member 23a can be suppressed, and an appropriate operational feeling can be given to the user when the operating portion 10 and the sleeve 11 are rotated relative to each other.
- the sliding contact portion 100 is integrally fixed to the fixed shaft member 23a. According to this configuration, compared to the case where an O-ring or the like is attached to either the sleeve 11 or the fixed shaft member 23a before the sleeve 11 and the fixed shaft member 23a are set, the assembling process of the feeding container 1 is reduced. The number of attached parts can be reduced. Moreover, since the sliding contact portion 100 is integrally fixed to the fixed shaft member 23a, when the sleeve 11 and the fixed shaft member 23a are set or when the dispensing container 1 is operated, the sliding contact portion 100 does not move between the sleeve 11 and the fixed shaft member 23a. It is possible to suppress positional displacement with respect to the member 23a.
- the sliding contact portion 100 is integrally fixed to the inner surface of the circumferential groove 24c, accommodated in the circumferential groove 24c of the outer sleeve 11a, and moves within the circumferential groove 24c as the outer sleeve 11a rotates. It was set as the structure by which the lower protrusion 11c was formed. According to this configuration, a moderate frictional resistance can be applied between the sliding contact portion 100 and the lower projection 11c, and the engagement between the lower projection 11c and the circumferential groove 24c causes the outer sleeve 11a and the fixed shaft to move. Vertical displacement with respect to the member 23a can be suppressed. As a result, it is possible to reduce the size of the feeding container 1 in the vertical direction, for example, as compared with the case where, for example, an engaging portion in the vertical direction is provided separately from the sliding contact portion with the O-ring.

Description
本願は、2021年5月31日に日本に出願された特願2021-091035号に基づき優先権を主張し、その内容をここに援用する。
また、繰出容器の組立工程において、スリーブと基筒との間にOリングを介在させるには、基筒にOリングを装着した後、スリーブを基筒に組み付ける必要がある。そのため、Oリングのセット性に関して未だ改善の余地がある。すなわち、Oリングが基筒に装着されているだけの構成であるため、セット時において、スリーブ(及び基筒)に対するOリングの上下方向の位置にばらつきが生じ易い。この場合には、繰出容器の商品毎で摩擦抵抗にばらつきが生じたり、ばらつきを調整するために製造効率が低下したりする可能性がある。また、仮に所望の位置にOリングがセットされたとしても、繰出容器の操作に伴いOリングが上下方向にずれる可能性もある。
本開示の一態様に係る繰出容器は、上下方向に延びるとともに、螺旋溝が形成された伝達軸を有する操作部と、前記伝達軸の外側を取り囲み、前記伝達軸の軸線回りに回転可能に設けられたスリーブと、前記スリーブに対する前記軸線回りの回転が規制された状態で、上下方向に移動可能に前記スリーブの内側に設けられるとともに、内容物を保持する中皿本体と、前記中皿本体から下方に延び、前記螺旋溝に係合する係合突起を有する可動軸と、を備え、前記スリーブ及び前記操作部のうち、一方の部材には、前記一方の部材よりも軟材質で形成されるとともに、前記スリーブ及び前記操作部の相対回転に伴い他方の部材が摺接する摺接部が固着されている。
この構成によれば、スリーブと操作部とのセット前にスリーブ及び操作部の何れかに対してOリング等を装着させる場合に比べ、繰出容器の組立工程での組付部品を削減できる。
しかも、摺接部が一方の部材に一体に固着されているので、スリーブと操作部とのセット時や繰出容器の操作時において、摺接部がスリーブや操作部に対して位置ずれするのを抑制できる。これにより、繰出容器の商品毎での摩擦抵抗のばらつきを抑制できる。また、ばらつき調整のため労力を軽減できるので、製造効率の向上を図ることができる。
その結果、組付点数の削減及びセット性を向上させつつ、商品性の高い繰出容器を提供できる。
この場合、摺接部と突部との間で適度な摩擦抵抗を作用させることができるとともに、突部と周溝との係合によってスリーブと操作部との上下方向の位置ずれを抑制できる。これにより、例えばOリングとの摺接箇所とは別に上下方向への係合箇所を設ける場合に比べ、繰出容器の上下方向での小型化を図ることができる。
この場合、摺接部とスリーブとが、スリーブの周方向の位置に関わらず、常に接触する。これにより、スリーブが操作部に安定して保持される。また、摺接部及び突部のそれぞれが全周に亘って延びている構成に比べ、摺接部及び突部間に作用する摩擦抵抗が過大になるのを抑制できる。そのため、スリーブと操作部との間に作用する摩擦抵抗を適度な範囲に調整し易い。
この場合、スリーブと固定軸部材とを組み付けた後に、スリーブ及び操作部をまとめて外装体に組み付けることができる。これにより、突部と摺接部との位置合わせを事前に行うことができるため、繰出容器の商品毎での摩擦抵抗のばらつきを抑制できる。
図1に示す繰出容器1は、棒状内容物(不図示)を繰り出して使用する。棒状内容物は、例えば化粧料(口紅やリップクリーム、スティックアイシャドー等)や薬剤、糊等が挙げられる。
突部21hは、底壁21aから上方に向けて突出している。
スロープ部21jは、周方向の一方側から他方側に向かうに従い底壁21aからの突出高さが漸次高くなるように容器軸Oを中心として螺旋状に延びている。
固定軸部材23aは、外装体21に対して周方向に回転不能に設けられている。具体的に、固定軸部材23aは、嵌合筒24と、台座部25と、内側伝達軸(伝達軸)26と、第2位置決め部27と、を備えている。
嵌合筒24の下端部には、径方向の外側に張り出す張出部24bが形成されている。嵌合筒24の上部には、周溝24cが形成されている。周溝24cは、嵌合筒24の外周面上で開口するとともに、嵌合筒24の外周面上を周方向の全周に亘って延びている。
下突部11cは、外スリーブ11aの下端部において径方向の内側に突出している。下突部11cは、周溝24c内に収容された状態で、周溝24cの上端開口縁及び下端開口縁に係合する。これにより、外スリーブ11aは、操作部10に対する上下方向への移動が規制された状態で、周方向に回転可能に固定軸部材23aに支持されている。
上突部11dは、外スリーブ11aの中間部分(中具22の上端縁よりも下方であって、下突部11cよりも上方に位置する部分)から径方向の内側に突出している。
内スリーブ11bにおいて、ストッパ突部11gと周方向で異なる位置には、内スリーブ11bの内周面上で開口する第2規制溝11hが形成されている。第2規制溝11hは、上下方向に延びるとともに、内スリーブ11bの上下両端縁上で開放されている。
中皿本体51は、容器軸Oと同軸の有底筒状に形成されている。中皿本体51は、外スリーブ11aの内側において、内側伝達軸26の上方に位置する部分に収容されている。中皿本体51には、内容物が充填される。内容物は、中皿本体51から上方に突出した状態で充填される。
繰出容器1を使用する際には、まずキャップ13を操作部10から取り外す。次に、外スリーブ11a及び外装体21(周壁21f)をそれぞれ把持し、操作部10及びスリーブ11を繰出方向に相対回転させる。このとき、中具22及び固定軸部材23aは、外装体21にそれぞれ相対回転不能に取り付けられているため、外装体21、中具22及び固定軸部材23aが一体に回転する。一方、外スリーブ11a及び内スリーブ11b同士、並びに内スリーブ11b及び中皿12同士は、それぞれ相対回転不能に取り付けられているため、スリーブ11及び中皿12が一体に回転する。
この構成によれば、スリーブ11と固定軸部材23aとの間に摺接部100が介在することで、スリーブ11と固定軸部材23aとの間に摺接部100によって適度な摩擦抵抗を作用させることができる。これにより、スリーブ11と固定軸部材23aとの間のがたつきを抑制できるとともに、操作部10とスリーブ11とを相対回転させる際に使用者に対して適度な操作感覚を与えることができる。
この構成によれば、スリーブ11と固定軸部材23aとのセット前にスリーブ11及び固定軸部材23aの何れかに対してOリング等を装着させる場合に比べ、繰出容器1の組立工程での組付部品を削減できる。
しかも、摺接部100が固定軸部材23aに一体に固着されているので、スリーブ11と固定軸部材23aとのセット時や繰出容器1の操作時において、摺接部100がスリーブ11や固定軸部材23aに対して位置ずれするのを抑制できる。これにより、繰出容器1の商品毎での摩擦抵抗のばらつきを抑制できる。また、ばらつき調整のため労力を軽減できるので、製造効率の向上を図ることができる。
その結果、組付点数の削減及びセット性を向上させつつ、商品性の高い繰出容器1を提供できる。
この構成によれば、摺接部100と下突部11cとの間で適度な摩擦抵抗を作用させることができるとともに、下突部11cと周溝24cとの係合によって外スリーブ11aと固定軸部材23aとの上下方向の位置ずれを抑制できる。これにより、例えばOリングとの摺接箇所とは別に上下方向への係合箇所を設ける場合に比べ、繰出容器1の上下方向での小型化を図ることができる。
この構成によれば、摺接部100と外スリーブ11aとが、外スリーブ11aの周方向の位置に関わらず、常に接触する。これにより、外スリーブ11aが固定軸部材23aに安定して保持される。また、摺接部100及び下突部11cのそれぞれが全周に亘って延びている構成に比べ、摺接部100及び下突部11c間に作用する摩擦抵抗が過大になるのを抑制できる。そのため、スリーブ11と固定軸部材23aとの間に作用する摩擦抵抗を適度な範囲に調整し易い。
この構成によれば、外スリーブ11aと固定軸部材23aとを組み付けた後に、外スリーブ11a及び固定軸部材23aをまとめて外装体21に組み付けることができる。これにより、下突部11cと摺接部100との位置合わせを事前に行うことができるため、繰出容器1の商品毎での摩擦抵抗のばらつきを抑制できる。
上述した実施形態では、操作部10のうち、外装体21と固定軸部材23aとが別体で形成された構成について説明したが、この構成に限られない。操作部10は、外装体21と固定軸部材23aとが一体で形成されていてもよい。

上述した実施形態では、外装体21が有底筒状に形成された構成について説明したが、この構成に限られない。外装体21は、繰出容器1の操作時において使用者によって回転操作可能な把持部分が少なくとも外部に露出していればよい。
上述した実施形態では、摺接部100が操作部10とスリーブ11との間に径方向に挟まれる構成について説明したが、この構成に限られない。摺接部100は、操作部10とスリーブ11との間に上下方向で挟まれる構成等であってもよい。
上述した実施形態では、操作筒部として外装体21及び中具22を備える構成について説明したが、この構成に限られない。操作筒部は、外装体21のみを備えていてもよい。
上述した実施形態では、伝達軸の外周面に螺旋溝が形成され、可動軸が伝達軸の外側を取り囲む構成について説明したが、この構成に限られない。例えば、筒状の伝達軸の内周面に螺旋溝が形成され、係合突起を有する可動軸が伝達軸の内側に配置される構成であってもよい。
