しかしながら、従来の回転繰出容器では、内容物を繰り出し操作する際の操作性を向上することに改善の余地があった。   However, in the conventional rotary feeding container, there is room for improvement in improving the operability when feeding the contents.

本発明は、このような事情に鑑みてなされたものであって、内容物を繰り出し操作する際の操作性を向上できる回転繰出容器を提供することを目的としている。   This invention is made | formed in view of such a situation, Comprising: It aims at providing the rotation delivery container which can improve the operativity at the time of carrying out delivery operation of the contents.

本発明の一態様に係る回転繰出容器は、内容物が収容され、内容物を吐出する吐出口が形成された容器本体と、前記容器本体内に設けられ、前記容器本体に対して容器軸方向に沿って移動する中皿と、前記容器本体及び前記中皿のうち、いずれか一方に設けられて容器軸方向に延び、外周面に螺旋溝が形成された螺旋軸と、前記容器本体及び前記中皿のうち、前記一方とは異なる他方に設けられて前記螺旋溝に係合された係合部と、前記容器本体内に設けられ、前記螺旋軸と前記係合部とを容器軸回りに相対回転させる操作部と、を備え、前記操作部の外周面は、前記容器本体を形成する材質よりも軟らかく弾性変形可能な材質で形成され、前記容器本体の外周面に開口する開口部から、容器外部に露出していることを特徴とする。   A rotary dispensing container according to an aspect of the present invention includes a container main body in which contents are stored and a discharge port for discharging the contents is formed, and is provided in the container main body, the container axial direction with respect to the container main body An inner pan that moves along the container body, and the container main body and the intermediate dish provided in any one of them, extending in the container axial direction, and having a spiral groove formed on the outer peripheral surface, the container main body and the container An engagement portion provided on the other side of the intermediate dish that is different from the one and engaged with the spiral groove, and provided in the container main body, the spiral shaft and the engagement portion are arranged around the container axis. An operation portion that rotates relative to each other, and an outer peripheral surface of the operation portion is formed of a material that is softer and elastically deformable than a material that forms the container main body, and an opening that opens to the outer peripheral surface of the container main body, It is exposed outside the container.

この回転繰出容器では、容器本体及び中皿のうち、いずれか一方に螺旋軸が設けられ、前記一方とは異なる他方に、螺旋軸の螺旋溝に係合する係合部が設けられている。また、螺旋軸と係合部とを容器軸回りに相対回転させる操作部が設けられており、この操作部を回転操作することにより、螺旋溝と係合部との係合作用（ねじ作用）によって中皿は、容器本体内を容器軸方向に沿って吐出口側へ向けて移動することができ、吐出口から内容物が吐出される。   In this rotating and feeding container, a spiral shaft is provided in one of the container main body and the inner dish, and an engaging portion that engages with a spiral groove of the spiral shaft is provided on the other side different from the one. In addition, an operation portion that relatively rotates the spiral shaft and the engagement portion around the container axis is provided. By rotating the operation portion, an engagement action (screw action) between the spiral groove and the engagement portion is provided. Thus, the inner tray can move in the container body along the container axial direction toward the discharge port, and the contents are discharged from the discharge port.

そして、操作部の外周面は、容器本体を形成する材質よりも軟らかく弾性変形可能な材質で形成されている。つまり操作部の外周面は、容器本体よりも軟らかい例えばエラストマー等の弾性変形可能な材質（軟質材）からなり、指先等にフィットして操作時のグリップ性がよい。従って、たとえ容器の外径が小さく抑えられている場合でも、操作部を回転操作する際の操作性は良好に確保される。   And the outer peripheral surface of the operation part is formed of a material that is softer and elastically deformable than the material forming the container body. That is, the outer peripheral surface of the operation portion is made of an elastically deformable material (soft material) such as an elastomer that is softer than the container main body, and fits a fingertip or the like and has a good grip property during operation. Therefore, even when the outer diameter of the container is kept small, the operability when rotating the operation portion is ensured satisfactorily.

操作部の外周面は、容器本体の外周面に開口する開口部から容器外部に露出している。このため、容器本体の開口部に露出する操作部の外周面部分を回転操作することにより、容器本体から内容物を吐出させることができる。
そして、操作部の外周面のうち、容器本体の開口部から容器外部に露出する部分以外の部位については、容器本体内に配設される。また操作部の外周面のうち、開口部から容器外部に露出する部分については、グリップ性が向上した分、露出面積を小さく抑えることができる。これにより、例えば、開口部から露出する操作部の外周面部分を、容器本体の外周面から径方向外側へ向けて大きく突出させずに配置することができる。従って、操作部の外周面をエラストマー等の軟質材で形成しつつも、容器の外観デザインに与える影響を小さく抑えることができる。 The outer peripheral surface of the operation part is exposed to the outside of the container from an opening that opens to the outer peripheral surface of the container body. For this reason, the contents can be discharged from the container main body by rotating the outer peripheral surface portion of the operation portion exposed at the opening of the container main body.
And about the outer peripheral surface of an operation part, parts other than the part exposed to the container exterior from the opening part of a container main body are arrange | positioned in a container main body. Moreover, about the part exposed to the container exterior from an opening part among the outer peripheral surfaces of an operation part, an exposed area can be restrained small by the part which the grip property improved. Thereby, for example, the outer peripheral surface portion of the operation portion exposed from the opening can be arranged without greatly projecting radially outward from the outer peripheral surface of the container main body. Therefore, the influence on the external appearance design of the container can be reduced while the outer peripheral surface of the operation portion is formed of a soft material such as an elastomer.

以上より本発明によれば、内容物を繰り出し操作する際の操作性を向上できる。特に、容器の外径を小さく抑えたり外観のデザイン性を高めたりしつつ、操作性を向上することが可能である。   As described above, according to the present invention, it is possible to improve the operability when the contents are fed out. In particular, it is possible to improve the operability while keeping the outer diameter of the container small and improving the appearance design.

また、上記回転繰出容器において、容器軸に垂直な横断面視で、前記容器本体は非真円形状をなしていることが好ましい。   Further, in the above rotary feeding container, it is preferable that the container main body has a non-circular shape in a cross-sectional view perpendicular to the container axis.

この場合、容器軸に垂直な横断面視で、容器本体が非真円形状をなしている。従って、容器本体の形状に対応するように、中皿を容器の横断面視で非真円形状に形成し、容器本体内に中皿を嵌合させることにより、容器本体に対する中皿の回転を容易に規制することができる。また、容器本体が非真円形状であるので、容器の外観デザイン性を高めやすい。   In this case, the container body has a non-circular shape in a cross-sectional view perpendicular to the container axis. Therefore, the inner pan is formed in a non-circular shape in a cross-sectional view of the container so as to correspond to the shape of the container main body, and the middle pan is fitted into the container main body, thereby rotating the inner pan relative to the container main body. It can be easily regulated. Moreover, since the container body is non-circular, it is easy to improve the appearance design of the container.

また、上記回転繰出容器において、前記操作部の半径は、前記容器本体の外周面のうち最も径方向内側に位置する部分の半径よりも大きく、前記容器本体の外周面のうち最も径方向外側に位置する部分の半径よりも小さいことが好ましい。   Further, in the above rotary delivery container, the radius of the operation portion is larger than the radius of the outermost surface of the container body that is located on the innermost radial direction, and is the outermost surface of the container body on the outermost radial direction. It is preferable that it is smaller than the radius of the part located.

この場合、操作部の半径が、容器本体の外周面のうち最も径方向内側に位置する部分の半径よりも大きいので、操作部の外周面のうち、容器本体の開口部から容器外部に露出される部分が、該容器本体の外周面よりも径方向外側に向けて出っ張るため、操作性をより向上させることができる。
また、操作部の半径が、容器本体の外周面のうち最も径方向外側に位置する部分の半径よりも小さいので、操作部を容器本体内に確実に収容できる。 In this case, since the radius of the operation portion is larger than the radius of the outermost surface of the container main body located at the innermost radial direction, the outer peripheral surface of the operation portion is exposed to the outside of the container from the opening of the container main body. Therefore, the operability can be further improved since the portion protruding from the outer peripheral surface of the container main body protrudes radially outward.
In addition, since the radius of the operation part is smaller than the radius of the outermost surface of the container main body that is located on the outermost radial direction, the operation part can be reliably accommodated in the container main body.

本発明の回転繰出容器によれば、内容物を繰り出し操作する際の操作性を向上できる。   According to the rotating and feeding container of the present invention, the operability when the contents are fed out can be improved.

A helical shaft (male screw shaft 4) extending in the container axis O direction and having a helical groove (male screw portion 38) formed on the outer peripheral surface, and the container body 3 and the inner plate 5 are provided on the other side different from the one. An engaging portion (female screw portion 28) engaged with the helical shaft, an operation portion 6 provided in the container main body 3 to relatively rotate the helical shaft and the engaging portion around the container axis O, and the container main body 3 And a cap 7 that is detachably mounted and covers the discharge port 2.
In the example of the present embodiment, the spiral shaft is provided in the inner tray 5, and the engaging portion is provided in the container body 3. In addition, the operation unit 6 is disposed in the end of the container body 3 on the side opposite to the discharge port 2 along the container axis O direction.

Further, the spiral axis has an axial shape. The container main body 3, the helical shaft (male screw shaft 4), the inner tray 5, the operation unit 6 and the cap 7 are arranged in a state where their respective central axes are located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, the direction from the operation unit 6 toward the cap 7 along the container axis O direction (vertical direction) is referred to as the upper side, and the direction from the cap 7 toward the operation unit 6 is referred to as the lower side. . In addition, a direction orthogonal to the container axis O in a plan view viewed from the container axis O direction is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

容器本体３は、容器軸Ｏ方向に延びる本体筒８と、本体筒８の上端部に配設され、吐出口２が形成された塗布筒９と、本体筒８の下端部に配設され、該本体筒８の下端開口部を覆うカバー筒１０と、本体筒８、塗布筒９及びカバー筒１０に対して周方向に回転自在に設けられた雌ねじ筒２６と、を備えている。   The container body 3 is disposed at the main body cylinder 8 extending in the container axis O direction, at the upper end portion of the main body cylinder 8, the application cylinder 9 in which the discharge port 2 is formed, and at the lower end portion of the main body cylinder 8, A cover cylinder 10 that covers the lower end opening of the main body cylinder 8, and a female screw cylinder 26 that is rotatably provided in the circumferential direction with respect to the main body cylinder 8, the application cylinder 9, and the cover cylinder 10.

本体筒８は、筒状をなしており、周壁を有している。本実施形態の例では図４に示されるように、容器軸Ｏに垂直な断面視（横断面視）で、本体筒８の周壁は非真円形状をなしている。本実施形態の例では本体筒８の周壁が、多角形筒状に形成されている。   The main body cylinder 8 has a cylindrical shape and has a peripheral wall. In the example of the present embodiment, as shown in FIG. 4, the peripheral wall of the main body cylinder 8 has a non-circular shape in a cross-sectional view (transverse cross-sectional view) perpendicular to the container axis O. In the example of this embodiment, the peripheral wall of the main body cylinder 8 is formed in a polygonal cylinder shape.

具体的に、容器軸Ｏに垂直な断面視で、本体筒８は四角形状をなしており、互いに平行に延びる一対の長辺と、長辺に垂直に延び、互いに平行な一対の短辺と、長辺と短辺との間に配置されてこれらを滑らかに接続する４つのコーナＲと、を有している。つまり、容器の横断面視において本体筒８は、長辺が延在する長手方向（長軸方向）の長さ（外形寸法）が長く、短辺が延在する短手方向（短軸方向）の長さが短い、長方形状をなしている。本実施形態の例では、容器の横断面視で本体筒８の長辺及び短辺が、直線状、又は、径方向外側へ向けて膨出する曲線状をなしている。   Specifically, in a cross-sectional view perpendicular to the container axis O, the main body cylinder 8 has a quadrangular shape, and a pair of long sides extending in parallel to each other, and a pair of short sides extending perpendicular to the long sides and parallel to each other, , And four corners R arranged between the long side and the short side to smoothly connect them. That is, in the cross-sectional view of the container, the main body cylinder 8 has a long length (external dimension) in which the long side extends (long axis direction) and a short direction (short axis direction) in which the short side extends. The length is short and rectangular. In the example of the present embodiment, the long side and the short side of the main body cylinder 8 in a cross sectional view of the container are linear or curved so as to bulge outward in the radial direction.

本体筒８の周壁の外周面のうち、上端部には、該上端部と下端部との間に位置する中間部分よりも径方向内側に位置する塗布筒嵌合部１１が形成されている。塗布筒嵌合部１１も、容器の横断面視で四角形状（多角形筒状）をなしている。塗布筒嵌合部１１の外周面のうち、容器の横断面視における本体筒８の長手方向（図１、図３及び図４における左右方向）の両端部には、径方向外側へ向けて突出する上方凸部１３が一対形成されている。   Of the outer peripheral surface of the peripheral wall of the main body cylinder 8, an application cylinder fitting part 11 is formed at the upper end part, which is positioned radially inward from the intermediate part located between the upper end part and the lower end part. The application cylinder fitting part 11 also has a quadrangular shape (polygonal cylinder shape) in a cross-sectional view of the container. Out of the outer peripheral surface of the coating tube fitting portion 11, it protrudes outward in the radial direction at both ends in the longitudinal direction of the main body tube 8 in the cross-sectional view of the container (left and right direction in FIGS. 1, 3, and 4). A pair of upper convex portions 13 is formed.

本実施形態の例では、操作部６が、円筒状に形成されている。操作部６は、少なくともその周壁の外周面が、容器本体３を形成する材質よりも軟らかく弾性変形可能な材質で形成されている。本実施形態では、操作部６全体が、例えばエラストマー等の弾性変形可能な材質（軟質材）で形成されている。操作部６の周壁は、雌ねじ筒２６の大径筒部２７の周壁の径方向外側に嵌合している。   In the example of the present embodiment, the operation unit 6 is formed in a cylindrical shape. The operation unit 6 is formed of a material that is elastically deformable at least on the outer peripheral surface of the peripheral wall thereof softer than the material forming the container body 3. In the present embodiment, the entire operation unit 6 is formed of an elastically deformable material (soft material) such as an elastomer. The peripheral wall of the operation portion 6 is fitted to the outer side in the radial direction of the peripheral wall of the large diameter cylindrical portion 27 of the female screw cylinder 26.

A pair of extending annular retaining flanges 33 are formed. Of the pair of retaining flanges 33, the retaining flange 33 located above is in contact with the top wall of the large-diameter cylindrical portion 27 from above. Of the pair of retaining flanges 33, the retaining flange 33 positioned below is in contact with the lower end opening edge of the peripheral wall of the large-diameter cylindrical portion 27 from below.

そして、図２〜図４に示されるように、操作部６の外周面は、容器本体３の外周面に開口する開口部２５から、容器外部に露出している。本実施形態の例では、操作部６の外周面が、容器本体３の外周面のうち最も径方向内側に位置する部分に開口する開口部２５から、容器外部に露出している。なお、容器本体３の外周面のうち最も径方向内側に位置する部分は、容器の横断面視における本体筒８の一対の長辺の各中央部に相当する。
本実施形態の例では、容器を径方向から見た側面視（正面視）において開口部２５を正面に見て、操作部６の外周面のうち、開口部２５から容器外部に露出する部分（具体的には後述するように、開口部２５から容器外部に張り出す部分）の形状が、前記側面視における開口部２５の形状に対応して、四角形状とされている。つまり、開口部２５と、該開口部２５から露出する操作部６の外周面部分とが、互いに略同一形状とされている。また図４に示されるように、開口部２５の開口縁と、操作部６の外周面とは、互いに接近配置されている。 As shown in FIGS. 2 to 4, the outer peripheral surface of the operation unit 6 is exposed to the outside of the container from the opening 25 that opens to the outer peripheral surface of the container main body 3. In the example of the present embodiment, the outer peripheral surface of the operation unit 6 is exposed to the outside of the container from the opening 25 that opens at the most radially inner portion of the outer peripheral surface of the container body 3. In addition, the part located in the radial direction innermost part among the outer peripheral surfaces of the container main body 3 is corresponded to each center part of a pair of long side of the main body cylinder 8 in the cross sectional view of a container.
In the example of the present embodiment, when the opening 25 is viewed in front in a side view (front view) when the container is viewed from the radial direction, a portion of the outer peripheral surface of the operation unit 6 exposed from the opening 25 to the outside of the container ( Specifically, as will be described later, the shape of the portion protruding from the opening 25 to the outside of the container is a quadrangular shape corresponding to the shape of the opening 25 in the side view. That is, the opening 25 and the outer peripheral surface portion of the operation unit 6 exposed from the opening 25 have substantially the same shape. Moreover, as FIG. 4 shows, the opening edge of the opening part 25 and the outer peripheral surface of the operation part 6 are mutually arranged close.

また本実施形態において、操作部６の半径は、容器本体３の外周面のうち最も径方向内側に位置する部分の半径よりも大きく、容器本体３の外周面のうち最も径方向外側に位置する部分の半径よりも小さい。具体的に、操作部６の外周面の半径（外半径）は、容器本体３のカバー筒１０の外周面のうち最も径方向内側に位置する部分の半径（外半径の最小値）よりも大きく、容器本体３のカバー筒１０の外周面のうち最も径方向外側に位置する部分の半径（外半径の最大値）よりも小さくされている。   Further, in the present embodiment, the radius of the operation portion 6 is larger than the radius of the outermost surface of the container body 3 that is located on the innermost side in the radial direction, and is located on the outermost surface of the container body 3 in the outermost radial direction. It is smaller than the radius of the part. Specifically, the radius (outer radius) of the outer peripheral surface of the operation unit 6 is larger than the radius (minimum value of the outer radius) of the outermost surface of the cover cylinder 10 of the container body 3 that is located on the innermost radial direction. The radius of the outermost surface of the cover cylinder 10 of the container body 3 that is located on the outermost radial direction is smaller than the maximum radius of the outer radius.

容器本体３の開口部２５から容器外部に露出した操作部６の部分を、指先等により容器軸Ｏ回りに回転操作することで、本体筒８に対して、操作部６とともに雌ねじ筒２６が回転する。 Therefore, a portion of the outer peripheral surface of the operation unit 6 that is exposed to the outside of the container from the opening 25 of the container main body 3 is disposed so as to protrude radially outward from the outer peripheral surface of the container main body 3. Further, portions of the outer peripheral surface of the operation unit 6 other than the portion exposed from the opening 25 to the outside of the container are accommodated in the container main body 3.

Accordingly, by removing the cap 7 from the container main body 3 and rotating the operation portion 6, the inner tray 5 moves inside the container main body 3 through the container axis O by the engagement action (screw action) between the spiral groove and the engagement portion. It can move toward the discharge port 2 along the direction, and the contents are discharged from the discharge port 2.

そして、操作部６の外周面は、容器本体３を形成する材質よりも軟らかく弾性変形可能な材質で形成されている。つまり操作部６の外周面は、容器本体３よりも軟らかい例えばエラストマー等の弾性変形可能な材質（軟質材）からなり、指先等にフィットして操作時のグリップ性がよい。従って、たとえ容器の外径が小さく抑えられている場合でも、操作部６を回転操作する際の操作性は良好に確保される。またこの効果により、容器のコンパクト化（特に小径化）も可能になる。   The outer peripheral surface of the operation unit 6 is formed of a material that is softer and elastically deformable than the material forming the container body 3. That is, the outer peripheral surface of the operation unit 6 is made of a material (soft material) that is softer than the container body 3 and can be elastically deformed, such as an elastomer, and fits a fingertip or the like to provide a good grip during operation. Therefore, even when the outer diameter of the container is kept small, the operability when rotating the operation portion 6 is ensured satisfactorily. This effect also makes it possible to make the container compact (especially to reduce the diameter).

操作部６の外周面は、容器本体３の外周面に開口する開口部２５から容器外部に露出している。このため、容器本体３の開口部２５に露出する操作部６の外周面部分を回転操作することにより、容器本体３から内容物を吐出させることができる。
そして、操作部６の外周面のうち、容器本体３の開口部２５から容器外部に露出する部分以外の部位については、容器本体３内に配設される。また操作部６の外周面のうち、開口部２５から容器外部に露出する部分については、グリップ性が向上した分、露出面積を小さく抑えることができる。これにより、開口部２５から露出する操作部６の外周面部分を、容器本体３の外周面から径方向外側へ向けて大きく突出させずに配置することができる。従って、操作部６の外周面をエラストマー等の軟質材で形成しつつも、容器の外観デザインに与える影響を小さく抑えることができる。 The outer peripheral surface of the operation unit 6 is exposed to the outside of the container from an opening 25 that opens to the outer peripheral surface of the container body 3. For this reason, the contents can be discharged from the container body 3 by rotating the outer peripheral surface portion of the operation unit 6 exposed at the opening 25 of the container body 3.
And about the outer peripheral surface of the operation part 6, parts other than the part exposed to the exterior of a container from the opening part 25 of the container main body 3 are arrange | positioned in the container main body 3. FIG. Moreover, about the part exposed to the exterior of a container from the opening part 25 among the outer peripheral surfaces of the operation part 6, since the grip property improved, the exposed area can be restrained small. Thereby, the outer peripheral surface part of the operation part 6 exposed from the opening part 25 can be arrange | positioned, without projecting greatly toward the radial direction outer side from the outer peripheral surface of the container main body 3. FIG. Therefore, the influence on the external appearance design of the container can be reduced while the outer peripheral surface of the operation unit 6 is formed of a soft material such as an elastomer.

以上より本実施形態によれば、内容物を繰り出し操作する際の操作性を向上できる。特に、容器の外径を小さく抑えたり外観のデザイン性を高めたりしつつ、操作性を向上することが可能である。   As described above, according to the present embodiment, it is possible to improve the operability when the contents are fed out. In particular, it is possible to improve the operability while keeping the outer diameter of the container small and improving the appearance design.

また本実施形態では、容器軸Ｏに垂直な横断面視で、容器本体３が非真円形状をなしている。従って、容器本体３の形状に対応するように、中皿５を容器の横断面視で非真円形状に形成し、容器本体３内に中皿５を嵌合させることにより、容器本体３に対する中皿５の回転を容易に規制することができる。また、容器本体３が非真円形状であるので、容器の外観デザイン性を高めやすい。   In the present embodiment, the container body 3 has a non-circular shape in a cross-sectional view perpendicular to the container axis O. Therefore, the inner tray 5 is formed in a non-circular shape in a cross-sectional view of the container so as to correspond to the shape of the container main body 3, and the inner tray 5 is fitted into the container main body 3, thereby The rotation of the inner tray 5 can be easily regulated. Moreover, since the container main body 3 is non-circular, it is easy to improve the external appearance design of the container.

また本実施形態では、操作部６の半径が、容器本体３の外周面のうち最も径方向内側に位置する部分の半径よりも大きいので、操作部６の外周面のうち、容器本体３の開口部２５から容器外部に露出される部分が、該容器本体３の外周面よりも径方向外側に向けて出っ張るため、操作性をより向上させることができる。
また、操作部６の半径が、容器本体３の外周面のうち最も径方向外側に位置する部分の半径よりも小さいので、操作部６を容器本体３内に確実に収容できる。 In the present embodiment, the radius of the operation unit 6 is larger than the radius of the outermost surface of the container body 3 that is located on the innermost side in the radial direction. Since the portion exposed from the portion 25 to the outside of the container protrudes radially outward from the outer peripheral surface of the container body 3, the operability can be further improved.
Further, since the radius of the operation portion 6 is smaller than the radius of the outermost surface of the container body 3 that is located on the outermost radial direction, the operation portion 6 can be reliably accommodated in the container body 3.

また本実施形態では、容器の側面視（正面視）において開口部２５を正面に見て、開口部２５が四角形孔状をなしており、該開口部２５から露出する（開口部２５から容器外部へ張り出す）操作部６の外周面部分が、開口部２５の形状に対応する四角形状をなしている。つまり、開口部２５と、該開口部２５から露出する操作部６の外周面部分とが、互いに略同一形状とされている。このため、開口部２５の開口縁と、操作部６の外周面との間に形成される隙間を小さく抑えることができる。これにより、前記隙間を通して容器内部に異物等が浸入するようなことを防止でき、かつ容器外観の見栄えを良くすることができる。   Further, in the present embodiment, the opening 25 has a square hole shape when viewed from the front in a side view (front view) of the container, and is exposed from the opening 25 (from the opening 25 to the outside of the container). The outer peripheral surface portion of the operation unit 6 has a quadrangular shape corresponding to the shape of the opening 25. That is, the opening 25 and the outer peripheral surface portion of the operation unit 6 exposed from the opening 25 have substantially the same shape. For this reason, the clearance gap formed between the opening edge of the opening part 25 and the outer peripheral surface of the operation part 6 can be restrained small. Thereby, it can prevent that a foreign material etc. penetrate | invade into the inside of a container through the said clearance gap, and can improve the appearance of a container external appearance.

また本実施形態では、互いに螺着される雄ねじ部３８と雌ねじ部２８とが、二条ねじであるため、一条ねじである構成と比べて、ねじのリードが大きくなる。すなわち、雄ねじ部３８と雌ねじ部２８との、容器軸Ｏ回りの相対的な単位回転量（例えば１回転）あたりの容器軸Ｏ方向へ向けた相対的な移動量（変位量）を、大きくすることができる。従って、操作部６を回転させることにより、容器本体３内において中皿５を速やかに容器軸Ｏ方向に移動させることができ、少ない回転量で多くの内容物を吐出口２から吐出させることができる。   In the present embodiment, the male screw portion 38 and the female screw portion 28 that are screwed to each other are double-threaded screws, so that the lead of the screw is larger than that of a single-threaded configuration. That is, the relative movement amount (displacement amount) of the male screw portion 38 and the female screw portion 28 in the direction of the container axis O per unit rotation amount (for example, one rotation) around the container axis O is increased. be able to. Therefore, by rotating the operation unit 6, the inner tray 5 can be quickly moved in the direction of the container axis O in the container body 3, and a large amount of contents can be discharged from the discharge port 2 with a small amount of rotation. it can.

なお、本発明は前述の実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。   Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

例えば、前述の実施形態では、雄ねじ軸（螺旋軸）４が、中皿５に設けられており、雌ねじ部（係合部）２８が、容器本体３に設けられているとしたが、これに限定されるものではない。すなわち、雄ねじ軸（螺旋軸）４が、容器本体３に設けられており、雌ねじ部（係合部）２８が、中皿５に設けられていてもよい。
この場合、例えば、容器本体３の本体筒８内に、該本体筒８に対して回転自在に雄ねじ軸４を設け、この雄ねじ軸４に操作部６を装着する。また中皿５に、上下方向に貫通する貫通孔を設け、この貫通孔の内周面に雌ねじ部２８を形成し、該雌ねじ部２８に雄ねじ軸４の雄ねじ部（螺旋溝）３８を螺着すればよい。なおこの場合、容器本体３内において雄ねじ軸４が、中皿５を上下方向に貫通して吐出口２付近（容器本体３の上端部）まで延設されていることが好ましい。 For example, in the above-described embodiment, the male screw shaft (spiral shaft) 4 is provided in the inner plate 5 and the female screw portion (engagement portion) 28 is provided in the container body 3. It is not limited. That is, the male screw shaft (spiral shaft) 4 may be provided in the container body 3, and the female screw portion (engagement portion) 28 may be provided in the inner plate 5.
In this case, for example, a male screw shaft 4 is provided in the main body cylinder 8 of the container main body 3 so as to be rotatable with respect to the main body cylinder 8, and the operating portion 6 is mounted on the male screw shaft 4. Further, a through hole penetrating in the vertical direction is provided in the inner plate 5, a female screw portion 28 is formed on the inner peripheral surface of the through hole, and a male screw portion (spiral groove) 38 of the male screw shaft 4 is screwed to the female screw portion 28. do it. In this case, it is preferable that the male screw shaft 4 extends in the vertical direction in the container body 3 to the vicinity of the discharge port 2 (upper end portion of the container body 3).

また前述の実施形態では、螺旋軸が雄ねじ軸４であり、螺旋溝が雄ねじ部３８であり、係合部が雌ねじ部２８であるとしたが、これらは、ねじに限定されるものではない。すなわち、例えば螺旋軸の外周面に、通常のねじよりもリードの大きな螺旋溝を形成し、この螺旋溝に対して、突起状の係合部を係合してもよい。   In the above-described embodiment, the helical shaft is the male screw shaft 4, the helical groove is the male screw portion 38, and the engaging portion is the female screw portion 28, but these are not limited to screws. That is, for example, a spiral groove having a lead larger than that of a normal screw may be formed on the outer peripheral surface of the spiral shaft, and a protruding engagement portion may be engaged with the spiral groove.

また前述の実施形態では、操作部６が円筒状に形成されているとしたが、これに限定されるものではない。すなわち、操作部６は、例えば円筒状以外の円柱状、正多角形筒状、正多角形柱状、球状等に形成されていてもよい。なお、操作部６が球状に形成される場合には、容器本体３の開口部２５は、該操作部６の外周面の形状に対応して、円形孔状に形成されることが好ましい。
また操作部６は、雌ねじ筒２６（の大径筒部２７）に、一体にインサート成形されていてもよい。この場合、操作部６の回転操作によって、雌ねじ筒２６から操作部６が離脱するようなことが防止される。 Moreover, in the above-mentioned embodiment, although the operation part 6 was formed in the cylindrical shape, it is not limited to this. That is, the operation unit 6 may be formed in, for example, a columnar shape other than a cylindrical shape, a regular polygonal cylindrical shape, a regular polygonal column shape, a spherical shape, or the like. In addition, when the operation part 6 is formed in a spherical shape, the opening 25 of the container body 3 is preferably formed in a circular hole shape corresponding to the shape of the outer peripheral surface of the operation part 6.
Moreover, the operation part 6 may be insert-molded integrally with the internal thread cylinder 26 (large diameter cylinder part 27). In this case, the operation unit 6 is prevented from being detached from the female screw cylinder 26 by the rotation operation of the operation unit 6.

また前述の実施形態では、操作部６の半径が、容器本体３の外周面のうち最も径方向内側に位置する部分の半径よりも大きくされているとしたが、これに限定されるものではない。すなわち、操作部６は、その外周面が容器本体３の開口部２５から容器外部に露出してさえいればよく（つまり操作可能であればよいことから）、例えば操作部６の半径が、容器本体３の外周面のうち最も径方向内側に位置する部分の半径より小さくてもよく、或いは同等であってもよい。   Moreover, in the above-mentioned embodiment, although the radius of the operation part 6 was made larger than the radius of the part located radially innermost among the outer peripheral surfaces of the container main body 3, it is not limited to this. . That is, it is only necessary that the outer peripheral surface of the operation unit 6 be exposed to the outside of the container from the opening 25 of the container body 3 (that is, the operation unit 6 only needs to be operable). The radius may be smaller than or equal to the radius of the outermost surface of the main body 3 located on the innermost radial direction.

また、前述の実施形態では、容器本体３及び中皿５を、容器軸Ｏに垂直な横断面視で非真円形状に形成して、互いに嵌合させることにより、容器本体３に対する中皿５の回転を規制することとした。具体的に、前述の実施形態では、この非真円形状として、容器本体３の内周面及び中皿５の外周面を、容器の横断面視で四角形状（多角形状）に形成した一例を挙げて説明したが、これに限定されるものではない。すなわち、容器の横断面視における非真円形状には、例えば、上記四角形状以外の多角形状、楕円形状、真円形状の円周上の少なくとも一部に平面部や凹部、凸部等が形成された形状等、種々の形状が含まれる。   In the above-described embodiment, the container body 3 and the middle dish 5 are formed in a non-circular shape in a cross-sectional view perpendicular to the container axis O, and are fitted to each other, whereby the middle dish 5 with respect to the container body 3 is obtained. It was decided to regulate the rotation. Specifically, in the above-described embodiment, an example in which the inner peripheral surface of the container body 3 and the outer peripheral surface of the inner dish 5 are formed in a quadrangular shape (polygonal shape) in a cross-sectional view of the container as the non-circular shape. Although described above, the present invention is not limited to this. That is, the non-circular shape in the cross-sectional view of the container includes, for example, a flat portion, a concave portion, a convex portion, etc. on at least a part of the circumference of the polygonal shape other than the rectangular shape, the elliptical shape, and the perfect circular shape. Various shapes such as a shaped shape are included.

或いは、容器本体３及び中皿５を、容器軸Ｏに垂直な横断面視で真円形状に形成して互いに嵌合させ、容器本体３と中皿５との間に、容器軸Ｏ方向に延びるリブと溝とを係合させた回り止め手段等を設けることにより、容器本体３に対する中皿５の回転を規制することとしてもよい。
なお、容器の横断面視で容器本体３を真円形状に形成する場合には、容器本体３と操作部６とを二重筒状に配置するとともに、互いの周壁同士を接近配置して、容器本体３の外周面に開口された開口部２５から、操作部６の外周面を露出させればよい。これにより、本発明の上述した作用効果を得ることができる。 Alternatively, the container body 3 and the middle dish 5 are formed in a perfect circle shape in a cross-sectional view perpendicular to the container axis O and fitted to each other, and the container body 3 and the middle dish 5 are disposed in the container axis O direction. The rotation of the inner tray 5 with respect to the container body 3 may be restricted by providing a detent means or the like in which the extending rib and the groove are engaged.
In addition, when forming the container body 3 in a perfect circle shape in a cross-sectional view of the container, the container body 3 and the operation unit 6 are arranged in a double cylinder shape, and the peripheral walls are arranged close to each other, What is necessary is just to expose the outer peripheral surface of the operation part 6 from the opening part 25 opened by the outer peripheral surface of the container main body 3. FIG. Thereby, the effect mentioned above of the present invention can be obtained.

その他、本発明の趣旨を逸脱しない範囲で、上記した実施の形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上記した実施形態及び変形例を適宜組み合わせてもよい。   In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in above-mentioned embodiment with a well-known component, and you may combine above-mentioned embodiment and modification suitably.
