例えば特許文献1には、上端に繰り出し口を備える筒状のケースと、ケースの内部に配置され、且つ、ケースに対する周方向一方側への相対回転を阻止される中皿と、ケースに相対回転可能に連結する操作部材と、ケースに対する操作部材の相対回転を周方向一方側に許容するとともに周方向他方側に阻止するラチェット機構部と、を有し、操作部材が、中皿に螺合し、且つ、ケースに対する操作部材の周方向一方側への相対回転によってケースに対して中皿を上方に相対移動させるねじ軸を有する繰り出し容器が記載されている。 For example, Patent Document 1 describes a tubular case having a feeding port at the upper end, a middle plate arranged inside the case and prevented from rotating relative to one side in the circumferential direction with respect to the case, and relative rotation to the case. It has an operating member that can be connected to the case and a ratchet mechanism that allows the relative rotation of the operating member with respect to the case on one side in the circumferential direction and blocks it on the other side in the circumferential direction, and the operating member is screwed into the middle plate. Moreover, a feeding container having a screw shaft for moving the middle plate upward with respect to the case by relative rotation of the operating member with respect to the case in the circumferential direction is described.

このようにラチェット機構部を有する繰り出し容器によれば、中皿が内容物を繰り入れる方向に動作することを阻止することができるので、例えば、内容物が比較的柔らかい場合に繰り入れによって内容物に形状の崩れや破断などの損傷が生じてしまうことを抑制することができる。 As described above, according to the feeding container having the ratchet mechanism portion, it is possible to prevent the inner plate from moving in the direction in which the contents are fed. Therefore, for example, when the contents are relatively soft, the contents are shaped into the contents by feeding. It is possible to prevent damage such as collapse or breakage of the ratchet.

In this embodiment, the content 10 is a substantially columnar lipstick. The solid content 10 means a substance having a hardness sufficient to retain its shape, and includes a substance having a certain degree of softness such as a semi-kneaded substance. The upper end surface of the content 10 housed in the replacement container 3 is provided flush with the feeding port 8a.

図1及び図2に示すように、上ケース8は、中心軸線Oを中心とする円筒状をなしており、上端に繰り出し口8aを形成している。なお、繰り出し口8aは、中心軸線Oに垂直な面に対して斜めに傾斜しているが、中心軸線Oに垂直であってもよい。 As shown in FIGS. 1 and 2, the upper case 8 has a cylindrical shape centered on the central axis O, and a feeding port 8a is formed at the upper end thereof. Although the feeding port 8a is inclined diagonally with respect to the surface perpendicular to the central axis O, it may be perpendicular to the central axis O.

上ケース8の外周面における下部には、下ケース4の接続部4aに着脱可能に接続される被接続部8bが設けられている。接続部4aは中心軸線Oを中心とするらせん状の雌ねじ状をなしており、被接続部8bは中心軸線Oを中心とするらせん状の雄ねじ状をなしている。上ケース8の外周面における被接続部8bよりも上方の部分には、周方向に延びる円環状のフランジ8cが設けられている。フランジ8cの下面が、下ケース4の上端に設けられた環状段部4bの上面に当接するまで被接続部8bを接続部4aにねじ込むことにより、被接続部8bが接続部4aに接続され、これにより上ケース8が下ケース4に装着される。また、接続部4a及び被接続部8bのねじの回転方向は、後述するねじ軸6aのねじ部6eのねじの回転方向と同じ向きとなっている。本実施の形態では、ねじ部6eが左ねじであるので、接続部4a及び被接続部8bも左ねじとされている。したがって、上ケース8が下ケース4に装着された状態では、下ケース4に対する上ケース8の周方向一方側への相対回転が阻止されている。また、下ケース4に対する上ケース8の周方向他方側への相対回転により、上ケース8が下ケース4から離脱させられる。 At the lower part of the outer peripheral surface of the upper case 8, a connected portion 8b that is detachably connected to the connecting portion 4a of the lower case 4 is provided. The connecting portion 4a has a spiral female screw shape centered on the central axis O, and the connected portion 8b has a spiral male screw shape centered on the central axis O. An annular flange 8c extending in the circumferential direction is provided on the outer peripheral surface of the upper case 8 above the connected portion 8b. The connected portion 8b is connected to the connecting portion 4a by screwing the connected portion 8b into the connecting portion 4a until the lower surface of the flange 8c abuts on the upper surface of the annular step portion 4b provided at the upper end of the lower case 4. As a result, the upper case 8 is attached to the lower case 4. Further, the rotation direction of the screws of the connecting portion 4a and the connected portion 8b is the same as the rotation direction of the screw of the screw portion 6e of the screw shaft 6a described later. In the present embodiment, since the threaded portion 6e is a left-hand thread, the connecting portion 4a and the connected portion 8b are also left-handed. Therefore, when the upper case 8 is attached to the lower case 4, the relative rotation of the upper case 8 to one side in the circumferential direction with respect to the lower case 4 is prevented. Further, the upper case 8 is separated from the lower case 4 by the relative rotation of the upper case 8 to the other side in the circumferential direction with respect to the lower case 4.

操作部材5の周壁部5aにおける4つの摺動抵抗付与片5eよりも上方の部分には、周方向に並ぶ4つの螺合片5fが設けられている。各々の螺合片5fは、周壁部5aの上端から下方に延びるスリットにより形成されており、固定端から上方に上下方向に沿って延びる片持ち梁状をなしている。各々の螺合片5fの自由端の内周面には、螺合部5gが設けられている。4つの螺合部5gは全体として、中心軸線Oを中心とする間欠らせん状の雌ねじ状をなしている。各々の螺合部5gはねじ軸6aのねじ部6eに螺合している。また、各々の螺合片5fの自由端の外周面には突起5hが設けられている。各々の螺合片5fの外周面が突起5hを介して上ケース8の支持面8hに支持されることにより、螺合部5gがねじ部6eに螺合した状態が維持される。なお、突起5hを設けることなく、螺合部5gがねじ部6eに螺合した状態が維持されるように、各々の螺合片5fの外周面を上ケース8の支持面8hによって支持する構成としてもよい。また、螺合片5fの数は適宜設定可能である。 Four screw pieces 5f arranged in the circumferential direction are provided in a portion of the peripheral wall portion 5a of the operating member 5 above the four sliding resistance imparting pieces 5e. Each screw piece 5f is formed by a slit extending downward from the upper end of the peripheral wall portion 5a, and has a cantilever shape extending upward from the fixed end in the vertical direction. A screw portion 5g is provided on the inner peripheral surface of the free end of each screw piece 5f. The four screwed portions 5g have an intermittent spiral female screw shape centered on the central axis O as a whole. Each threaded portion 5g is screwed into the threaded portion 6e of the screw shaft 6a. Further, a protrusion 5h is provided on the outer peripheral surface of the free end of each screw piece 5f. Since the outer peripheral surface of each screw piece 5f is supported by the support surface 8h of the upper case 8 via the protrusion 5h, the state in which the screw portion 5g is screwed to the screw portion 6e is maintained. The outer peripheral surface of each screw piece 5f is supported by the support surface 8h of the upper case 8 so that the screwed portion 5g is maintained in a state of being screwed to the threaded portion 6e without providing the protrusion 5h. May be. Further, the number of screw pieces 5f can be appropriately set.

各々の螺合片5fは、支持面8hに支持されない状態では、ねじ軸6aのねじ部6eから第1所定値の押圧力で下方に上下方向に沿って押圧されることにより、ねじ軸6aのねじ部6eに対する螺合部5gの螺合が外れるように径方向外側に弾性変形するように構成されている。 When each screw piece 5f is not supported by the support surface 8h, the screw shaft 6a is pressed downward from the screw portion 6e of the screw shaft 6a with a pressing force of a first predetermined value in the vertical direction. It is configured to elastically deform outward in the radial direction so that the screw portion 5g with respect to the screw portion 6e is unscrewed.

上述したように付け替え容器3が本体容器2に装着された繰り出し容器1の使用を開始する際は、図5に示すように、キャップ7を取り外した状態で、例えば下ケース4と操作部材5の把持部5cをそれぞれ把持し、下ケース4に対して操作部材5を周方向一方側に相対回転させる順方向の回転操作を行う。その際、操作部材5は、下ケース4に対して下方への相対移動が規制されており、ねじ軸部材6は、中皿9に対する上ケース8の嵌合部8fの嵌合が外れる第3所定値の押圧力で下ケース4に対して上方に相対移動することができ、且つ、下ケース4に対して上ケース8と中皿9を介した連結により周方向一方側への相対回転が阻止されている。したがって、嵌合部8fの嵌合が外れる強さの順方向の回転操作により、操作部材5の螺合部5gがねじ軸部材6のねじ部6eを押し上げ、ねじ軸部材6が中皿9を押し上げ、中皿9が内容物10を押し上げ、それにより、内容物10を繰り出し口8aから繰り出すことができる。嵌合部8fの嵌合が外れた後は、順方向の回転操作を適宜行うことにより、ねじ軸部材6と中皿9を上昇させ、内容物10をさらに繰り出して使用することができる。 As described above, when the replacement container 3 starts to use the feeding container 1 mounted on the main body container 2, as shown in FIG. 5, with the cap 7 removed, for example, the lower case 4 and the operating member 5 Each of the gripping portions 5c is gripped, and a forward rotation operation is performed in which the operating member 5 is relatively rotated to one side in the circumferential direction with respect to the lower case 4. At that time, the operation member 5 is restricted from moving downward relative to the lower case 4, and the screw shaft member 6 is disengaged from the fitting portion 8f of the upper case 8 with respect to the middle plate 9. It is possible to move upward with respect to the lower case 4 with a pressing force of a predetermined value, and the relative rotation to one side in the circumferential direction is caused by the connection between the upper case 8 and the middle plate 9 with respect to the lower case 4. It has been blocked. Therefore, by the forward rotation operation of the strength that the fitting portion 8f is disengaged, the screw portion 5g of the operation member 5 pushes up the screw portion 6e of the screw shaft member 6, and the screw shaft member 6 pushes the middle plate 9. Pushing up, the middle plate 9 pushes up the content 10, whereby the content 10 can be fed out from the feeding port 8a. After the fitting portion 8f is disengaged, the screw shaft member 6 and the middle plate 9 can be raised and the contents 10 can be further extended and used by appropriately performing a forward rotation operation.

一方、下ケース4に対して操作部材5を周方向他方側に相対回転させる逆方向の回転操作が過誤等により行われた場合には、ラチェット機構部12により、そのような逆方向の相対回転は阻止される。したがって、内容物10が比較的柔らかい口紅等である場合に、繰り入れによって内容物10に形状の崩れや破断などの損傷が生じてしまうことを抑制することができる。 On the other hand, if a reverse rotation operation for rotating the operation member 5 relative to the other side in the circumferential direction with respect to the lower case 4 is performed due to an error or the like, the ratchet mechanism unit 12 performs such a relative rotation in the reverse direction. Is blocked. Therefore, when the content 10 is a relatively soft lipstick or the like, it is possible to prevent the content 10 from being damaged such as being deformed or broken due to the feeding.

図6(a)に示すように、内容物10は、ねじ軸部材6の空回り部6fが螺合部5gに到達して空回りする上昇限界位置までねじ軸部材6が上昇するまで、繰り出して使用することができる。また、このとき、抜け止め部6gにより、ねじ軸部材6が操作部材5から抜け出てしまうことが抑制される。 As shown in FIG. 6A, the content 10 is extended and used until the screw shaft member 6 rises to the ascending limit position where the idle portion 6f of the screw shaft member 6 reaches the screwed portion 5 g and spins idle. can do. Further, at this time, the retaining portion 6g prevents the screw shaft member 6 from coming out of the operating member 5.

内容物10を実質的に使い切ったときなどにおいては、図6(a)~(c)に示すように、下ケース4に対して上ケース8を周方向他方側に相対回転させて接続部4aから被接続部8bを離脱させることにより、付け替え容器3を本体容器2から取り外し、廃棄することができる。そして、残った本体容器2は、内容物10の使用前の状態の別の付け替え容器3とともに再使用することができる。 When the contents 10 are substantially used up, as shown in FIGS. 6A to 6C, the upper case 8 is rotated relative to the lower case 4 on the other side in the circumferential direction to connect the connecting portion 4a. By separating the connected portion 8b from the main body container 2, the replacement container 3 can be removed from the main body container 2 and discarded. Then, the remaining main body container 2 can be reused together with another replacement container 3 in the state before use of the content 10.

その再使用に際しては、図7(a)~(c)に示す要領で付け替え容器3を本体容器2に装着することができる。具体的には、まず、流通時のケースから取り出した付け替え容器3の下端をねじ軸部材6の上端に被せ、中皿9の係合部9dでねじ軸部材6の被係合部6cを第1所定値以上の押圧力で下方に押圧する。この押圧により、螺合片5fが径方向外側に弾性変形して螺合部5gとねじ部6eとの螺合が外れ、図7(b)に示すように、ねじ軸部材6が一気に下降限界位置まで下降する。ねじ軸部材6が下降限界位置に達すると、下ケース4に対して上ケース8を周方向一方側に相対回転させて接続部4aに被接続部8bをねじ込む。このねじ込みにより、中皿9の係合部9dがねじ軸部材6の被係合部6cに第2所定値以上の押圧力で下方に押圧される。したがって、上記のねじ込みにより、係合部9dが被係合部6cを下方に乗り越え、それにより、図7(c)に示すように上ケース8の支持面8hが螺合片5fの外周面を支持可能な位置まで下降し、本体容器2に対する付け替え容器3の装着が完了する。 When the container is reused, the replacement container 3 can be attached to the main body container 2 as shown in FIGS. 7 (a) to 7 (c). Specifically, first, the lower end of the replacement container 3 taken out from the case at the time of distribution is put on the upper end of the screw shaft member 6, and the engaged portion 6c of the screw shaft member 6 is placed on the engaging portion 9d of the middle plate 9. 1 Press downward with a pressing force of a predetermined value or more. Due to this pressing, the screw piece 5f is elastically deformed outward in the radial direction, the screw portion 5g and the screw portion 6e are unscrewed, and as shown in FIG. 7B, the screw shaft member 6 is lowered to the lower limit at once. It descends to the position. When the screw shaft member 6 reaches the lowering limit position, the upper case 8 is relatively rotated to one side in the circumferential direction with respect to the lower case 4, and the connected portion 8b is screwed into the connecting portion 4a. By this screwing, the engaging portion 9d of the middle plate 9 is pressed downward by the engaged portion 6c of the screw shaft member 6 with a pressing force of a second predetermined value or more. Therefore, by the above screwing, the engaging portion 9d gets over the engaged portion 6c downward, whereby the support surface 8h of the upper case 8 covers the outer peripheral surface of the screw piece 5f as shown in FIG. 7C. It descends to a supportable position, and the attachment of the replacement container 3 to the main body container 2 is completed.

なお、付け替え容器3の装着に際しては、ねじ軸部材6を指で直接押し下げてもよいが、上述のように付け替え容器3で押し下げる方が装着の作業が容易である。 When mounting the replacement container 3, the screw shaft member 6 may be directly pushed down with a finger, but it is easier to push down the screw shaft member 6 with the replacement container 3 as described above.

本実施の形態では、付け替え容器3が上ケース8及び中皿9を有し、本体容器2が下ケース4、操作部材5、ラチェット機構部12及びねじ軸部材6を有している。したがって、本実施の形態によれば、ラチェット機構部12と付け替え容器3とを有する繰り出し容器1を実現することができる。 In the present embodiment, the replacement container 3 has an upper case 8 and a middle plate 9, and the main body container 2 has a lower case 4, an operation member 5, a ratchet mechanism portion 12, and a screw shaft member 6.

また、本実施の形態では、操作部材5が螺合片5fを有し、上ケース8が支持面8hを有している。したがって、本実施の形態によれば、付け替え容器3を本体容器2に付け替える際に、螺合片5fを径方向外側に弾性変形させることでねじ軸部材6を回転させることなく一気に下降限界位置まで下降させることができるので、良好な作業性を実現することができる。また、内容物10を繰り出す際には、支持面8hによって螺合片5fが径方向外側に弾性変形することを阻止し、螺合片5fとねじ軸部材6との螺合状態を維持することができるので、良好な操作性を確保することができる。 Further, in the present embodiment, the operating member 5 has the screw piece 5f, and the upper case 8 has the support surface 8h. Therefore, according to the present embodiment, when the replacement container 3 is replaced with the main body container 2, the screw piece 5f is elastically deformed outward in the radial direction to reach the lower limit position at once without rotating the screw shaft member 6. Since it can be lowered, good workability can be realized. Further, when the content 10 is unwound, the support surface 8h prevents the screw piece 5f from elastically deforming outward in the radial direction, and maintains the screwed state between the screw piece 5f and the screw shaft member 6. Therefore, good operability can be ensured.

また、本実施の形態では、付け替え容器3が係合部9dを有し、支持面8hが、係合部9dが被係合部6cを乗り越えることにより、螺合片5fの外周面を支持可能な位置に配置されるように構成されている。したがって、本実施の形態によれば、付け替え容器3を本体容器2に付け替える際に、付け替え容器3の係合部9dによってねじ軸部材6を下降限界位置まで押し下げることができるので、より一層、良好な作業性を実現することができる。 Further, in the present embodiment, the replacement container 3 has the engaging portion 9d, and the supporting surface 8h can support the outer peripheral surface of the screw piece 5f by the engaging portion 9d overcoming the engaged portion 6c. It is configured to be placed in various positions. Therefore, according to the present embodiment, when the replacement container 3 is replaced with the main body container 2, the screw shaft member 6 can be pushed down to the lowering limit position by the engaging portion 9d of the replacement container 3, which is even better. Workability can be realized.

また、本実施の形態では、ラチェット機構部12が、操作部材5に設けられる弾性片12bと、下ケース4の内周面に設けられる係合凸部12aと、を有している。したがって、本実施の形態によれば、ラチェット機構部12を簡単で小型の構造によって実現することができる。 Further, in the present embodiment, the ratchet mechanism portion 12 has an elastic piece 12b provided on the operating member 5 and an engaging convex portion 12a provided on the inner peripheral surface of the lower case 4. Therefore, according to the present embodiment, the ratchet mechanism portion 12 can be realized by a simple and compact structure.

The relative rotation of the screw shaft member 6 to one side in the circumferential direction is prevented, and the relative rotation of the screw shaft member 6 to one side in the circumferential direction with respect to the middle plate 9 is prevented, whereby the one side of the screw shaft member 6 in the circumferential direction with respect to the lower case 4 is prevented. Relative rotation to the side is blocked. Then, in the present embodiment, the connecting portion 4a has a spiral shape so that the replacement container 3 is mounted on the main body container 2 and the relative rotation of the upper case 8 to the lower case 4 in the circumferential direction is prevented. It is configured as a female screw. Further, this female thread is configured as a single thread.

しかし、接続部4aは2条以上の多条ねじとして構成してもよいし、らせん状以外の異形ねじとして構成してもよい。また、接続部4aは、下ケース4に対する上ケース8の周方向他方側への相対回転により被接続部8bにスナップ嵌合する周方向スナップ嵌合部4fを有してもよい。接続部4aが周方向スナップ嵌合部4fを有する場合、接続部4aのねじの回転方向は、ねじ部6eのねじの回転方向の逆向きとしてもよい。そのような変形例を図8に示す。なお、図8において、図1~図7に示す要素に対応する要素に同一の符号を付している。一方、被接続部8bはねじ状である必要はなく、接続部4aに螺合できる凸部であればよい。その逆に、上ケース8側の被接続部8bをねじ状に構成し、下ケース4側の接続部4aを被接続部8bに螺合できる凸部で構成してもよい。 However, the connecting portion 4a may be configured as a multi-threaded screw having two or more threads, or may be configured as a deformed screw other than the spiral shape. Further, the connecting portion 4a may have a circumferential snap fitting portion 4f that snap-fits to the connected portion 8b by the relative rotation of the upper case 8 to the other side in the circumferential direction with respect to the lower case 4. When the connecting portion 4a has the circumferential snap fitting portion 4f, the rotation direction of the screw of the connecting portion 4a may be opposite to the rotation direction of the screw of the screw portion 6e. An example of such a modification is shown in FIG. In FIG. 8, the same reference numerals are given to the elements corresponding to the elements shown in FIGS. 1 to 7. On the other hand, the connected portion 8b does not have to be screw-shaped, and may be a convex portion that can be screwed into the connecting portion 4a. On the contrary, the connected portion 8b on the upper case 8 side may be configured in a screw shape, and the connecting portion 4a on the lower case 4 side may be configured as a convex portion that can be screwed into the connected portion 8b.

また、接続部4a及び被接続部8bは、ねじとして構成されるものに限らず、例えば、下ケース4に対する上ケース8の下方への相対移動により接続部4aと被接続部8bとが互いにスナップ嵌合する上下方向スナップ嵌合部として構成してもよい。この場合、下ケース4に対する上ケース8の周方向の回り止め構造を適宜設ければよい。 Further, the connecting portion 4a and the connected portion 8b are not limited to those configured as screws, and for example, the connecting portion 4a and the connected portion 8b snap to each other due to the downward relative movement of the upper case 8 with respect to the lower case 4. It may be configured as a vertical snap fitting portion to be fitted. In this case, a detent structure for the upper case 8 in the circumferential direction with respect to the lower case 4 may be appropriately provided.

The ratchet mechanism 12 that allows the relative rotation of the operating member 5 with respect to the case 4 on one side in the circumferential direction and blocks it on the other side in the circumferential direction, and the ratchet mechanism portion 12 that is screwed into the operating member 5 and is relative to the lower case 4 in the circumferential direction. As long as it has a screw shaft member 6 that is prevented from rotating and that pushes up the middle plate 9 by relative rotation of the operating member 5 to one side in the circumferential direction with respect to the lower case 4, various changes can be made.

しかし、繰り出し容器1は、操作部材5が、ねじ軸6aに螺合する螺合部5gを内周面に備える径方向に弾性変形可能な螺合片5fを有し、上ケース8が、螺合部5gがねじ軸6aに螺合した状態を維持するために螺合片5fの外周面を支持する支持面8hを有するのが好ましい。 However, the feeding container 1 has a screw piece 5f in which the operating member 5 is provided with a screw portion 5g screwed to the screw shaft 6a on the inner peripheral surface and is elastically deformable in the radial direction, and the upper case 8 is screwed. It is preferable to have a support surface 8h that supports the outer peripheral surface of the screw piece 5f in order to maintain the state in which the joint portion 5g is screwed to the screw shaft 6a.

また、繰り出し容器1は、付け替え容器3が、ねじ軸6aに対する螺合部5gの螺合が外れるように螺合片5fを径方向外側に弾性変形させる第1所定値以上の押圧力でねじ軸6aの被係合部6cを下方に押圧可能である一方、第1所定値を超える第2所定値の押圧力で被係合部6cを弾性変形により下方に乗り越える係合部9dを有し、支持面8hが、係合部9dが被係合部6cを乗り越えることにより、螺合片5fの外周面を支持可能な位置に配置されるのが好ましい。 Further, in the feeding container 1, the replacement container 3 elastically deforms the screw piece 5f radially outward so that the screwing portion 5g is unscrewed with respect to the screw shaft 6a. While the engaged portion 6c of 6a can be pressed downward, it has an engaging portion 9d that overcomes the engaged portion 6c downward by elastic deformation with a pressing force of a second predetermined value exceeding the first predetermined value. It is preferable that the support surface 8h is arranged at a position where the outer peripheral surface of the screw piece 5f can be supported by the engaging portion 9d overcoming the engaged portion 6c.

また、繰り出し容器1は、ラチェット機構部12が、操作部材5に設けられ、径方向に弾性変形可能な弾性片12bと、下ケース4の内周面に設けられ、下ケース4に対する操作部材5の周方向一方側への相対回転により弾性片12bを乗り越えさせる一方、下ケース4に対する操作部材5の周方向他方側への相対回転により弾性片12bを係止する係合凸部12aと、を有するのが好ましい。 Further, in the feeding container 1, the ratchet mechanism portion 12 is provided on the operating member 5, and the elastic piece 12b that can be elastically deformed in the radial direction and the inner peripheral surface of the lower case 4 are provided, and the operating member 5 with respect to the lower case 4 is provided.
