Description

【０００１】
【発明の属する技術分野】
本発明は、アイペンシル（アイライン用，アイブロウ用等），口紅，リップクリーム等の棒状化粧料を容器から繰り出して使用する棒状化粧料容器に関するものである。
【０００２】
【従来の技術】
従来から、アイペンシル等の繰出容器として、図３４に示すような棒状化粧材繰出容器が提案されている（特開平１１−１４６８０８号公報）。この棒状化粧材繰出容器は、容器本体筒５１と、この容器本体筒５１に相対回転自在に連結された先筒５２と、これら両筒５１，５２内に軸方向に進退可能に収められた押棒５３とを備え、この押棒５３の先端に棒状化粧材５４を保持している。また、上記容器本体筒５１の内孔５１ａの内周面に、ラセン溝５５ａが形成されたメネジ部５５を突設し、上記押棒５３の外周面に、上記メネジ部５５のラセン溝５５ａと螺合する一群の突起５６を突設している。そして、上記押棒５３の下端部に、この押棒５３の前進限（ストロークエンド）を定めるフランジ５７を設け、上記前進限でメネジ部５５の下端面に押棒５３のフランジ５７の上面を当接させて押棒５３の前進を阻止するようにしている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記棒状化粧料容器では、押棒５３が前進限に到達したことを容器外から知ることができない。このため、押棒５３が前進限に到達したにもかかわらず、さらに両筒５１，５２を押棒５３の前進側に相対回動させて、これらを破損させるという問題がある。また、押棒５３が後進限に到達したときにも、同様の問題が発生する。
【０００４】
本発明は、このような事情に鑑みなされたもので、押棒が前進限もしくは後進限に到達したことを容器外から知ることができ、繰り出し機構に必要以上の負荷がかかるのを防ぐことができる棒状化粧料容器の提供をその目的とする。
【０００５】
【課題を解決するための手段】
上記の目的を達成するため、本発明の棒状化粧料容器は、本体筒部と、上記本体筒部の先端開口部に上記本体筒部に対して相対回転自在に取り付けられる先筒部と、先端部に棒状化粧料保持部が形成され上記両筒部の内孔内に進退自在に配設される棒状体と、上記本体筒部の内孔の所定部分に上記棒状体に外嵌する状態で配設された筒体とを備え、上記筒体の内周面にねじ部を形成するとともに、上記棒状体の外周面に、上記筒体のねじ部にねじ結合するねじ部を形成し、上記棒状体を先筒部に上下摺動自在に回動不能に係合させ、上記筒体の下端面に歯部を突設するとともに、上記本体筒部の内孔に、上記筒体の下端面が当接する段部を設け、上記段部に、上記筒体の歯部が噛み合う歯部を突設し、上記先筒部の下端面と本体筒部の段部との間に上記筒体の歯部と本体筒部の歯部とが噛み合った状態で筒体を挟み込み、上記筒体の上端面から凸部を上向きに突設し、上記凸部に対応する上記筒体の上端部の部分を残した状態で上記筒体に窓部を穿設してこの窓部内に撓みうるばね部を形成し、上記凸部を上記先筒部の下端面に常時弾性を有して当接させるように構成し、上記両筒部を相対回転させることにより棒状体を進退させ、上記棒状体の最大進出位置および最大後退位置において、上記両筒部を相対回転させたときなど、筒体および棒状体にある程度以上の負荷がかかった際に、上記ばね部が窓部内に撓んで上記筒体の歯部と本体筒部の歯部との噛み合いが外れ、筒体が本体筒部内で空転するように構成したという構成をとる。
【０００６】
すなわち、本発明の棒状化粧料容器は、本体筒部と、上記本体筒部の先端開口部に上記本体筒部に対して相対回転自在に取り付けられる先筒部と、先端部に棒状化粧料保持部が形成され上記両筒部の内孔内に進退自在に配設され、かつ先筒部に対して回動不能に摺動自在に係合する棒状体とを備えている。そして、上記本体筒部の内孔の所定部分に筒体を、上記棒状体に外嵌する状態で配設し、上記筒体の内周面にねじ部を形成するとともに、上記棒状体の外周面に、上記筒体のねじ部にねじ結合するねじ部を形成し、上記両筒部を相対回転させることにより、棒状体を進退させうるように構成している。また、上記筒体の下面に歯部を突設するとともに、上記本体筒部の内孔に、上記筒体が当接する段部を設け、この段部に、上記筒体の歯部が噛み合う歯部を突設し、筒体を先筒部と本体筒部の段部との間に回動不能に内装挟持している。したがって、本発明では、上記両筒部を相対回転させると、上記本体筒部の内孔の歯部と筒体の歯部とが係合しており、棒状体が先筒部に回動不能に係合しているため、棒状体を進退させることができる。また、上記棒状体の最大進出位置および最大後退位置のときに、上記両筒部を相対回転させると、棒状体は進退しないため、筒体に回転応力が加わり筒体の歯部が本体筒部の歯部を乗り越える。そして、上記筒体の歯部が本体筒部の歯部を乗り越えるときに、例えば、カチッという音が鳴り、この音を聞くことで、容器外から棒状体が最大進出位置もしくは最大後退位置に到達したことが判る。したがって、内部構造部に破壊的な応力をかけることがなくなっている。
【０００７】
本発明では、上記筒体の上端にばね部を形成し、筒体を先筒部および本体筒部に弾性を有して当接させているため、筒体が上下に弾発力を有した状態で挟持されており、先筒部と本体筒部を回転自在に連結させた際のガタツキを吸収させることができ、使用者に不快な感覚を与えなくて済む。
【０００８】
本発明では、筒体の上端にばね部を形成し、かつ、上記ばね部が筒体の側面に窓部を穿設し、筒体上端が窓部内に撓むよう構成しているため、本体筒部と先筒部との間に筒体が弾性を有して挟持されており、先筒部と本体筒部のガタツキを吸収することができ、ばね部の弾発力を調整することによって、筒体の空転開始トルクを調整することができる。
【０００９】
【発明の実施の形態】
つぎに、本発明の実施の形態を図面にもとづいて詳しく説明する。
【００１０】
図１および図２は本発明の棒状化粧料容器の一実施の形態を示している。これらの図において、１は本体筒部（図３参照）で、２は上記本体筒部１の先端開口部に上記本体筒部１に対して相対回転自在に取り付けられた先筒部（図４参照）で、３は先端部に保持部（棒状化粧料保持部）２６が形成され上記両筒部１，２の内孔１ａ，２ａ内に進退自在に配設される棒状体で、４は上記本体筒部１の内孔１ａ内に配設される筒体で、５は棒状体３の保持部２６に保持される棒状化粧料である。
【００１１】
より詳しく説明すると、上記本体筒部１は、円筒形状に形成されており、その内孔１ａには、小径下側内孔部１１と大径上側内孔部１２とが形成されている（図５参照）。上記小径下側内孔部１１には、その下端開口部に、中央貫通孔１３ａが穿設された底壁１３が形成されており、その上端面（すなわち、大径上側内孔部１２の下端面であって、小径下側内孔部１１と大径上側内孔部１２との円環状段部の上面）には下側ラチェット部１４が形成されている。
【００１２】
上記下側ラチェット部１４は、図６および図７に示すように、上記小径下側内孔部１１の上端面から上向に突設される８つの歯部（つめ部）１５からなり、それぞれ同形状の二等辺三角形に形成されている。これら各歯部１５の頂角αは鈍角（この実施の形態では、略１２６°）に形成されており、歯の高さｈは所定の高さ（この実施の形態では、略０．５ｍｍ）に形成されている。また、上記大径上側孔部１２には、図８に示すように、その上端部の内周面に大径部１２ａが形成されており、この大径部１２ａの中間高さ位置に円環状の溝１２ｂが形成されている。図６および図７において、１５ａは各歯部１５の頂部で、１５ｂは各歯部１５の底部である。
【００１３】
上記先筒部２は、図９に示すように、上記本体筒部１の大径上側内孔部１２の上部に回転自在に内嵌される下側筒部１７と、上記内嵌時に上記本体筒部１から突出する上側筒部１８とからなり、上記下側筒部１７の上端部の外周面に、図１０に示すように、上記大径上側内孔部１２の大径部１２ａに回転自在に大径部１７ａおよび上記大径上側内孔部１２の溝１２ｂに回転自在に係合する円環状の凸条１７ｂが形成されている。図において、１９は上記下側筒部１７の上端部の外周面に形成された円環状溝であり、Ｏリング２０（図２参照）が収容，固定される。このＯリング２０は、上記相対回転時に、所定の抵抗を持たせる作用をする。
【００１４】
また、上記上側筒部１８の内孔（すなわち、先筒部２の内孔２ａ）は、上端部の小径円筒面部２１と、この小径円筒面部２１に続く円錐台面部２２と、この円錐台面部２２に続く大径円筒面部２３とからなり、この大径円筒面部２３に、相対峙する２本の突条２４が上記内孔２ａの軸芯方向に沿って上記大径円筒面部２３の全長に形成されている（図１１および図１２参照）。そして、上記大径円筒面部２３の内周部分であって、上記両突条２４間に形成される部分２３ａに、後述する棒状体３の保持部２６の各扇状縦片２６ｂが摺動自在に係合し、上記両突条２４に、後述する棒状体３の切り欠き部２６ａ，縦溝２７が摺動自在に係合するようにして、棒状体３を先筒部２内に回動不能に、摺動自在にしている。
【００１５】
上記棒状体３（図１３〜図１５参照）の保持部２６は、円筒形状に形成された周側壁を、相対峙する２本の切り欠き部２６ａ（各切り欠き部２６ａの幅は、上記上側筒部１８の各突条２４の幅よりやや大きい）で上記棒状体３の軸芯方向に沿って切り欠いたもの、すなわち、一対の略半円弧状の縦片２６ｂで構成されており（図１６および図１７参照）、各縦片２６ｂが、上記大径円筒面部２３の内周部分の、上記両突条２４間に形成される部分２３ａに摺動自在に係合している。また、上記棒状体３の外周面には、上記両切り欠き部２６ａの下端部から下方に一直線状に延びる縦溝２７が、後述するねじ部２８まで形成されている（図１６および図１８参照。なお、図１６および図１８では、ねじ部２８の詳細は図示せず）。
【００１６】
また、上記棒状体３の下半部分（ただし、下端部を除く）の外周面には、後述する筒体４の内周面のねじ部３０にねじ結合（螺合）するねじ部２８が形成されている。このねじ部２８は、成形の都合上、上記棒状体３の下半部分の外周面に形成した連続ねじを、上記棒状体３の軸芯方向に沿って、相対峙する２箇所でカットした形状に形成されており、上記下半部分の外周面に上下に多段状に配設される各ねじ部２８の部分（上記両カット部間に形成された略半周ラセン突条のねじ部２８の部分）２８ａはそれぞそれ連続している（図１５および図１９参照）。また、上記棒状体３の下端部には、上記ねじ部２８より大径に形成された円柱形状のストッパー部２９が設けられている。
【００１７】
上記筒体４は、図２０〜図２２に示すように、円筒形状に形成されており、その内周面の下半部分には、４条ねじからなるねじ部３０が形成されている。このねじ部３０は、棒状体３のねじ部２８にねじ結合している。また、上記筒体４のねじ部２８は、上記本体筒部１の小径下側内孔部１１より大径に形成されており、これにより、上記小径下側内孔部１１の上端開口部に上記筒体４の下端が当接している。
【００１８】
また、上記筒体４には、その上端面から相対峙する状態で、上面が半円弧状に形成された一対の凸部３１が上向きに突設されている。また、上記筒体４の上端部には、上記両凸部３１の下側の部分に略四角形の第１切り欠き部（窓部）３２が形成されているとともに（図２３参照）、この第１切り欠き部３２の上辺と上記上端面とにわたって第２切り欠き部３３が形成されており、これら両切り欠き部３２，３３に挟まれた上記筒体４の上端部の部分（すなわち、第１切り欠き部３２の上側の部分）に、凸部３１を有する２組のばね片３４が形成されている。そして、これら両ばね片３４が、上記第１切り欠き部３２に撓みうるようにしている。また、上記両ばね片３４の凸部３１は、上記筒体４を本体筒部１の小径下側内孔部１１の上端面に当接した状態で、上記先筒部２の下側筒部１７の下端面に常時弾性を有して当接するようにしている。
【００１９】
また、上記筒体４の下端面には、上記本体筒部１の下側ラチェット部１４に係合する上側ラチェット部３７が形成されている。この上側ラチェット部３７は、図２４および図２５に示すように、上記下端面から下向きに突設される４つの歯部（つめ部）３８と、これら各歯部３８間に形成される平坦面３９とからなり、上記各歯部３８および各平坦面３９はそれぞれ、筒体４の周方向の長さが同じに形成され、等間隔おきに配設されている。また、上記各歯部３８は、それぞれ同形状の二等辺三角形であり、上記下側ラチェット部１４の各歯部１５と同じ形状に形成されている。すなわち、これら各歯部３８の頂角αは鈍角（この実施の形態では、略１２６°）に形成されており、各歯部３８の高さｈは所定の高さ（この実施の形態では、略０．５ｍｍ）に形成されている。図２４および図２５において、３８ａは各歯部３８の頂部で、３８ｂは各歯部３８の底部であり、これら底部３８ｂ間に上記平坦面３９が形成されている。
【００２０】
上記構成において、棒状化粧料５を繰り出す（進出させる）場合には、本体筒部１を先筒部２に対して所定の方向に相対回転させる（例えば、本体筒部１に対し先筒部２を時計回り方向に回転させる）ことを行う。すると、本体筒部１の下側ラチェット部１４と筒体４の上側ラチェット３７とが係合しているため（図２６参照）、本体筒部１と筒体４とが共回りし、先筒部２の突条２４と棒状体３の縦溝２７が摺動自在に回動不能に係合しているため、先筒部２と棒状体３とが共回りし、これにより、筒体４のねじ部３０と棒状体３のねじ部２８とのねじ結合により、棒状体３が進出し、これに伴い、棒状化粧料５に進出し、先筒部２の先端開口から飛び出す。
【００２１】
そして、棒状体３のストッパー部２９の上面が筒体４の下端面に当接すると、棒状体３が最大進出位置になる（図２７参照）。この状態で、さらに上記相対回転を行うと、棒状体３のストッパー部２９が筒体４の下端面に当接しているため、回転不能の状態となり、この回転トルクは筒体４に伝達される。この回転トルクがある程度以上になると、筒体４の上側ラチェット３７の歯部３８は、本体筒部１の下側ラチェット部１４の歯部１５で押し上げられ（図２８参照）、筒体４は棒状体３とともに僅かに回転しながら歯部１５の山の高さ分先端側に移動する。また、この移動に伴い、筒体４のばね片３４の凸部３１は先筒部２の下側筒部１７の下端面に当接したまま、ばね片３４は筒体４の第１切り欠き部３２内に撓む（図２１の矢印Ａ参照）。このとき、上記両歯部１５，３８の噛み合い角度（この実施の形態では、略１２６°）と、筒体４のねじ部３０のねじ溝の（筒体４の軸芯方向に対する）傾斜角度とが略同じであるため、筒体４は棒状体３の外周部をスムーズに旋回する。そして、下側ラチェット部１４の歯部１５が上側ラチェット３７の歯部３８を乗り越える時に（図２８の一点鎖線参照）、カチッという音が鳴る。乗り越えたのち、上記ばね片３４の戻り弾性力で、筒体４が押し下げられ（図２９参照）、筒体４は棒状体３とともに僅かに回転しながら歯部１５の山の高さ分後端側に移動する。このような動作を、上記相対回転をしている間、繰り返すため、カチッ，カチッという音を鳴らしながら、本体筒部１と先筒部２とは空回りする。
【００２２】
一方、棒状化粧料５を収める（後退させる）場合には、本体筒部１を先筒部２に対して上記回転方向と逆方向に相対回転させることを行う。すると、上記と同様にして、棒状体３が棒状化粧料５とともに後退し、先筒部２内に引き入れられる。
【００２３】
そして、棒状体３が最大後退位置になると、棒状体３のストッパー部２９の下面が本体筒部１の底壁１３の上面に当接する。このとき、棒状体３のねじ部２８と筒体４のねじ部３０とはねじ結合している（図１参照）。この状態で、さらに上記逆方向の相対回転を行っても、棒状体３は後退しないため、上記と同様にして、カチッ，カチッという音を鳴らしながら、本体筒部１と先筒部２とは空回りする。
【００２４】
上記のように、この実施の形態では、棒状体３が最大進出位置もしくは最大後退位置にあり、さらに回転操作を続行した場合、カチッ，カチッという音を鳴らしながら、本体筒部１と先筒部２とは空回りするため、この音を聞くことで、容器外から棒状体３が最大進出位置もしくは最大後退位置に到達したことが判る。また、このとき、上記本体筒部１と先筒部２とは空回りするため、本体筒部１，先筒部２，棒状体３および筒体４に無理な応力が働かず、破損等させることもない。
【００２５】
図３０は本発明の棒状化粧料容器の他の実施の形態を示している。この実施の形態では、上記実施の形態において、本体筒部１の底壁１３から、チップ４２を保持する保持筒４１を下向きに突設している。また、上記チップ４２を蓋する筒状蓋体４３を上記保持筒４１に着脱自在に外嵌，固定している。それ以外の部分は上記実施の形態と同様であり、同様の部分には同じ符号を付している。この実施の形態でも、上記実施の形態と同様の作用・効果を奏する。
【００２６】
図３１は本発明の棒状化粧料容器のさらに他の実施の形態を示している。この実施の形態では、図１および図２に示す実施の形態において、本体筒部１の底壁１３から、マスカラブラシ４４を保持する保持筒４５を下向きに突設している。また、上記マスカラブラシ４４を蓋する筒状蓋体４６を上記保持筒４５に着脱自在に外嵌，固定している。それ以外の部分は図１および図２に示す実施の形態と同様であり、同様の部分には同じ符号を付している。この実施の形態でも、図１および図２に示す実施の形態と同様の作用・効果を示す。
【００２７】
図３２および図３３は本発明の棒状化粧料容器のさらに他の実施の形態を示している。この実施の形態では、図１および図２に示す実施の形態で用いる、筒体４に第２切り欠き部３３を形成していない。それ以外の部分は図１および図２に示す実施の形態と同様であり、同様の部分には同じ符号を付している。この実施の形態でも、図１および図２に示す実施の形態と同様の作用・効果を示す。
【００２８】
【発明の効果】
以上のように、本発明の棒状化粧料容器によれば、本体筒部と、この本体筒部に相対回転自在に取り付けられる先筒部とを相対回転させると、上記本体筒部の内孔の歯部と筒体の歯部とが係合しているため、上記本体筒部と筒体とが共回りし、先筒部と棒状体が摺動自在に回動不能に係合しているため、先筒部と棒状体とが共回りし、これにより、上記両筒部の内孔内に配設された棒状体を進退させることができる。また、上記棒状体の最大進出位置および最大後退位置のときに、さらに上記両筒部を相対回転させると、この回転トルクは筒体に伝達される。この回転トルクがある程度以上になると、筒体の歯部を本体筒部の歯部で押し上げようとし、これにより、筒体に形成されたばね部が撓むとともに、筒体が棒状体の外周部を旋回しながら歯部の高さ分上昇し、ついには、筒体の歯部が本体筒部の歯部を乗り越え（この乗り越える瞬間、筒体の歯部と本体筒部の歯部との係合が外れる）、乗り越えたのちは、上記ばね部の弾性力で筒体が押し下げられ、筒体が棒状体の外周部を旋回しながら歯部の高さ分下降する。そして、上記筒体の歯部が本体筒部の歯部を乗り越えるときに、例えば、カチッという音が鳴り、この音を聞くことで、容器外から棒状体が最大進出位置もしくは最大後退位置に到達したことが判る。したがって、内部構造部に破壊的な応力をかけることがなくなっている。
【００２９】
本発明では、上記筒体の上端にばね部を形成し、筒体を先筒部および本体筒部に弾性を有して当接させているため、筒体が上下に弾発力を有した状態で挟持されており、先筒部と本体筒部を回転自在に連結させた際のガタツキを吸収させることができ、使用者に不快な感覚を与えなくて済む。
【００３０】
本発明では、筒体の上端にばね部を形成し、かつ、上記ばね部が筒体の側面に窓部を穿設し、筒体上端が窓部内に撓むよう構成しているため、本体筒部と先筒部との間に筒体が弾性を有して挟持されており、先筒部と本体筒部のガタツキを吸収することができ、ばね部の弾発力を調整することによって、筒体の空転開始トルクを調整することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a stick-shaped cosmetic container that uses a stick-shaped cosmetic such as an eye pencil (for eyeline, eyebrow, etc.), lipstick, lip balm and the like.
[0002]
[Prior art]
Conventionally, as a delivery container such as an eye pencil, a stick-shaped cosmetic material delivery container as shown in FIG. 34 has been proposed (Japanese Patent Laid-Open No. 11-146808). The stick-shaped cosmetic material supply container includes a container main body cylinder 51, a front cylinder 52 connected to the container main body cylinder 51 so as to be relatively rotatable, and a push rod which is accommodated in both cylinders 51 and 52 so as to be movable back and forth in the axial direction. 53, and a stick-shaped decorative material 54 is held at the tip of the push bar 53. Further, a female thread portion 55 having a helical groove 55 a formed on the inner peripheral surface of the inner hole 51 a of the container body cylinder 51 is projected, and the helical groove 55 a of the female thread portion 55 and the screw are formed on the outer peripheral surface of the push bar 53. A group of projections 56 to be joined is projected. A flange 57 is provided at the lower end of the push bar 53 to determine the advance limit (stroke end) of the push bar 53, and the upper surface of the flange 57 of the push bar 53 is brought into contact with the lower end surface of the female screw part 55 at the advance limit. The forward movement of the push bar 53 is prevented.
[0003]
[Problems to be solved by the invention]
However, in the bar-shaped cosmetic container, it cannot be known from the outside that the push bar 53 has reached the forward limit. For this reason, although the push rod 53 reaches the forward limit, there is a problem that both the cylinders 51 and 52 are further rotated relative to the forward side of the push rod 53 to damage them. The same problem occurs when the push bar 53 reaches the backward limit.
[0004]
The present invention has been made in view of such circumstances, and can know from the outside of the container that the push rod has reached the forward limit or the reverse limit, and can prevent an unnecessarily high load from being applied to the feeding mechanism. The purpose is to provide a stick-shaped cosmetic container.
[0005]

And if the upper surface of the stopper part 29 of the rod-shaped body 3 contact | abuts to the lower end surface of the cylinder 4, the rod-shaped body 3 will be in the maximum advance position (refer FIG. 27). If the relative rotation is further performed in this state, the stopper portion 29 of the rod-shaped body 3 is in contact with the lower end surface of the cylindrical body 4, so that the rotation is impossible, and this rotational torque is transmitted to the cylindrical body 4. . When this rotational torque exceeds a certain level, the teeth 38 of the upper ratchet 37 of the cylinder 4 are pushed up by the teeth 15 of the lower ratchet 14 of the main body cylinder 1 (see FIG. 28), and the cylinder 4 is rod-shaped. While slightly rotating together with the body 3, the tooth portion 15 moves toward the tip side by the height of the mountain. Further, along with this movement, the spring piece 34 remains in contact with the lower end surface of the lower cylindrical portion 17 of the front cylindrical portion 2 while the convex portion 31 of the spring piece 34 of the cylindrical body 4 is in contact with the first notch of the cylindrical body 4. It bends in the portion 32 (see arrow A in FIG. 21). At this time, the meshing angle of both the tooth portions 15 and 38 (in this embodiment, approximately 126 °), the inclination angle of the thread groove of the threaded portion 30 of the cylindrical body 4 (relative to the axial direction of the cylindrical body 4), Are substantially the same, the cylindrical body 4 smoothly turns around the outer periphery of the rod-shaped body 3. When the tooth portion 15 of the lower ratchet portion 14 gets over the tooth portion 38 of the upper ratchet 37 (see the one-dot chain line in FIG. 28), a clicking sound is generated. After climbing over, the cylindrical body 4 is pushed down by the return elastic force of the spring piece 34 (see FIG. 29), and the cylindrical body 4 slightly rotates together with the rod-shaped body 3 while the rear end corresponding to the height of the crest of the tooth portion 15. Move to the side. Since such an operation is repeated during the above relative rotation, the main body cylinder portion 1 and the front cylinder portion 2 idle while making a clicking sound.
[0022]
On the other hand, when the rod-shaped cosmetic 5 is stored (retracted), the main body cylinder portion 1 is relatively rotated with respect to the front tube portion 2 in the direction opposite to the rotation direction. Then, in the same manner as described above, the rod-shaped body 3 moves backward together with the rod-shaped cosmetic 5 and is drawn into the front tube portion 2.
[0023]
When the rod-like body 3 reaches the maximum retracted position, the lower surface of the stopper portion 29 of the rod-like body 3 comes into contact with the upper surface of the bottom wall 13 of the main body cylinder portion 1. At this time, the screw portion 28 of the rod-shaped body 3 and the screw portion 30 of the cylindrical body 4 are screw-coupled (see FIG. 1). In this state, even if the relative rotation in the opposite direction is further performed, the rod-like body 3 does not move backward, so that the main body cylinder portion 1 and the front cylinder portion 2 I go idle.
[0024]
As described above, in this embodiment, when the rod-shaped body 3 is in the maximum advanced position or the maximum retracted position and the rotation operation is further continued, the main body cylindrical portion 1 and the front cylindrical portion are sounded while clicking. 2 is idle, and by listening to this sound, it can be seen that the rod-like body 3 has reached the maximum advanced position or the maximum retracted position from outside the container. At this time, since the main body cylinder portion 1 and the front cylinder portion 2 are idle, excessive stress is not applied to the main body cylinder portion 1, the front cylinder portion 2, the rod-like body 3, and the cylinder body 4. Nor.
[0025]

【The invention's effect】
As described above, according to the stick-shaped cosmetic container of the present invention, when the main body cylinder part and the front cylinder part attached to the main body cylinder part are relatively rotatable, the inner hole of the main body cylinder part is formed. Since the tooth portion and the tooth portion of the cylindrical body are engaged, the main body cylindrical portion and the cylindrical body rotate together, and the front cylindrical portion and the rod-like body are slidably engaged so as not to rotate. For this reason, the front tube portion and the rod-shaped body rotate together, whereby the rod-shaped body disposed in the inner holes of the both tube portions can be advanced and retracted. Further, when the rod portions are further rotated relative to each other at the maximum advanced position and maximum retracted position of the rod-like body, this rotational torque is transmitted to the cylindrical body. When this rotational torque exceeds a certain level, it tries to push up the teeth of the cylinder with the teeth of the main body cylinder, which causes the spring formed in the cylinder to bend and the cylinder to turn the outer periphery of the rod-shaped body. While the tooth part of the cylindrical body climbs over the tooth part of the main body cylinder part, the engagement between the tooth part of the cylindrical body and the tooth part of the main body cylindrical part is finally reached. After getting over, the cylinder is pushed down by the elastic force of the spring part, and the cylinder descends by the height of the tooth part while turning around the outer periphery of the rod-like body. Then, when the tooth part of the cylindrical body gets over the tooth part of the main body cylindrical part, for example, a clicking sound is heard. By listening to this sound, the rod-like body reaches the maximum advanced position or maximum retracted position from the outside of the container. You can see that Therefore, destructive stress is not applied to the internal structure portion.
