Japanese Patent Laid-Open No. 11-276247

ここで、上記容器にあっては、クラッチ時に、筒状拡大部３ｎ，３ｎが半径方向に縮径するのと、元の位置に弾性復帰するのを繰り返すわけであるが、このクラッチ時に、基部３ｍの軸体部３ｂに対する根元部分の辺りに応力が集中しそこから後方に向かうひびＣが入り、破損する虞がある。特に、芯チャック３の構成材が硬い場合にはそれが顕著となる。   Here, in the container, the cylindrical enlarged portions 3n, 3n are repeatedly reduced in diameter in the radial direction during clutching and are elastically returned to their original positions. There is a risk that stress concentrates around the base portion of the 3 m shaft body portion 3b, and cracks C are caused to enter from there and break. In particular, when the constituent material of the core chuck 3 is hard, this becomes remarkable.

本発明は、このような課題を解決するために成されたものであり、クラッチ機能を十分に発揮しつつ芯チャックを始めとした移動体の破損を防止できる塗布材押出容器を提供することことを課題とする。   The present invention has been made to solve such a problem, and provides a coating material extruding container capable of preventing damage to a moving body such as a core chuck while sufficiently exhibiting a clutch function. Is an issue.

本発明による塗布材押出容器は、筒状を成し内周面に雌螺子を有する雌螺子部材と、軸状を成して容器内に配置され雌螺子と螺合する螺合突起が設けられた移動体と、を具備し、移動体は、その後端部を構成する基部と、この基部から一対が後方に突出して対向配置されその各々が半径方向に弾性を有すると共にその各々の外面に上記螺合突起が設けられた弾性突部と、を備え、雌螺子部材と移動体との相対回転により、雌螺子及び螺合突起より成る螺合部が働いて移動体が移動し、移動体の前進により容器内の塗布材が容器先端の開口から出現する塗布材押出容器であって、移動体が移動限に達した状態で当該移動体をそれ以上進めようとする過大な回転力が作用すると、弾性突部が半径方向に縮径し空転する塗布材押出容器において、基部であって一対の対向する弾性突部の側端部同士間の一方側に対応する位置に、半径方向外側及び後方に開放された凹部を有することを特徴としている。   The coating material extruding container according to the present invention is provided with a female screw member that has a cylindrical shape and has a female screw on the inner peripheral surface, and a threaded protrusion that is axially arranged in the container and screwed into the female screw. Each of the movable bodies has a base portion constituting the rear end portion thereof, and a pair of rearwardly projecting rearwardly from the base portion. An elastic protrusion provided with a threaded projection, and by the relative rotation of the female screw member and the movable body, the threaded portion composed of the female screw and the threaded projection works to move the movable body, When the forward movement is applied to the coating material extruding container in which the coating material in the container emerges from the opening at the tip of the container, and an excessive rotational force acts to advance the moving body further in a state where the moving body has reached the movement limit. In the coating material extruding container in which the elastic protrusion is radially reduced in diameter and idles, One corresponding to the side position between the side edge portions of a pair of opposing elastic projections in, is characterized by having a recess which is open radially outwardly and rearwardly.

このような塗布材押出容器によれば、移動体の後端部を構成する基部であって一対の対向する弾性突部の側端部同士間の一方側に対応する位置に、半径方向外側及び後方に開放される凹部が設けられるため、当該凹部により、クラッチ時に集中しようとする応力が分散・開放され、移動体の破損が防止される。また、当該凹部は、側端部同士間の両方側に対応する位置に設けられているのでは無く、側端部同士間の一方側に対応する位置のみに設けられているため、弾性突部の元の位置への弾性復帰（復元）が確実に行われ、クラッチ機能を十分に発揮できる。なお、凹部が側端部同士間の両方側に対応する位置に設けられている場合には、応力の分散・開放は成されるが、弾性突部の元の位置への弾性復帰が行われない場合があり、好ましくない。   According to such a coating material extruding container, at the position corresponding to one side between the side end portions of the pair of opposing elastic protrusions, which is the base portion constituting the rear end portion of the moving body, Since the concave portion opened rearward is provided, the concave portion disperses / releases the stress to be concentrated at the time of clutching, thereby preventing the moving body from being damaged. In addition, since the concave portion is not provided at a position corresponding to both sides between the side end portions, but is provided only at a position corresponding to one side between the side end portions, the elastic protrusion The elastic return (restoration) to the original position is surely performed, and the clutch function can be sufficiently exhibited. In addition, when the concave portion is provided at a position corresponding to both sides between the side end portions, the stress is dispersed / released, but the elastic protrusion is returned to the original position. It may not be present and is not preferred.

ここで、移動限としては、前進限及び後退限の少なくとも一方が挙げられる。   Here, the movement limit includes at least one of a forward limit and a backward limit.

また、凹部は、前方にも開放され溝とされていると、応力が一層分散・開放され、移動体の破損が一層防止される。   Further, if the concave portion is also opened to the front to form a groove, the stress is further dispersed and released, and the moving body is further prevented from being damaged.

また、溝は、基部を支持し前方に延在する軸体部も切り欠く構成であると、応力が一層分散・開放され、移動体の破損が一層防止される。   Further, when the groove is configured to cut out the shaft body portion that supports the base portion and extends forward, the stress is further dispersed and released, and the moving body is further prevented from being damaged.

また、基部の略中央に、前方へ凹む別の凹部を備え、当該別の凹部と上記凹部とが連通していると、応力が一層分散・開放され、移動体の破損が一層防止される。   In addition, when another concave portion that is recessed forward is provided in the approximate center of the base, and the other concave portion and the concave portion communicate with each other, stress is further dispersed and released, and damage to the moving body is further prevented.

このように本発明によれば、クラッチ機能を十分に発揮しつつ移動体の破損を防止できる塗布材押出容器を提供することが可能となる。   As described above, according to the present invention, it is possible to provide a coating material extruding container capable of preventing the moving body from being damaged while sufficiently exhibiting the clutch function.

このような構成を有する塗布材押出容器１００にあっては、使用者が、本体筒１１と先筒１２とを繰り出し方向である一方向に相対回転すると、螺合部１４及び回り止め部１５に従い、塗布材支持体１３が前進し、塗布材支持体１３にその後端部が支持された塗布材が先筒１２の先端の開口１２ａから出現する一方で、使用者が、本体筒１１と先筒１２とを繰り戻し方向である他方向（一方向の反対方向）に相対回転すると、塗布材支持体１３が後退し、塗布材が先筒１２の先端の開口１２ａから没入する。   In the coating material extruding container 100 having such a configuration, when the user relatively rotates the main body tube 11 and the front tube 12 in one direction which is the feeding direction, the screw member 14 and the rotation stopper 15 are followed. The coating material support 13 advances, and the coating material whose rear end portion is supported by the coating material support 13 appears from the opening 12a at the tip of the front tube 12, while the user moves the main body tube 11 and the front tube. 12 is rotated in the other direction (the opposite direction of one direction), which is the rewinding direction, the coating material support 13 is retracted, and the coating material is immersed from the opening 12 a at the tip of the front tube 12.

そして、図２及び図３に示すように、塗布材支持体１３の基部１３ｍの先端面１３ｇが先筒１２の後端面１２ｇに突き当たって塗布材支持体１３が前進限に達し、また、図１に示すように、塗布材支持体１３の弾性突部１３ｎの後端面１３ｈが本体筒１１の雌螺子１１ｘの後側の終端１１ｈに突き当たって塗布材支持体１３が後退限に達し、これらの移動限でさらに塗布材支持体１３をそれ以上進めようとする過大な回転力が作用すると、繰出機構の保護を図るべく、弾性突部１３ｎ，１３ｎが半径方向に縮径し空転する所謂クラッチとして機能する。   2 and 3, the tip surface 13g of the base portion 13m of the coating material support 13 abuts against the rear end surface 12g of the front tube 12, so that the coating material support 13 reaches the forward limit, and FIG. As shown in FIG. 4, the rear end face 13h of the elastic projection 13n of the coating material support 13 abuts on the rear end 11h of the female screw 11x of the main body cylinder 11, and the coating material support 13 reaches the retreat limit, and these movements When an excessive rotational force is applied to further advance the coating material support 13 as far as possible, the elastic projections 13n and 13n function as so-called clutches that are reduced in diameter in the radial direction and run idle in order to protect the feeding mechanism. To do.

ここで、本実施形態の塗布材押出容器１００にあっては、塗布材支持体１３の後端部において一対の弾性突部１３ｎ，１３ｎを支える基部１３ｍに対して、前述した溝１３ｓが設けられているため、当該溝１３ｓにより、クラッチ時に集中しようとする応力が分散・開放され、塗布材支持体１３の破損（従来技術で図９を用いて説明した基部３ｍに生じるひびＣ参照）が防止されている。また、当該溝１３ｓは、側端部１３ｐ，１３ｑ同士間の両方側に対応する位置に設けられているのでは無く、側端部１３ｐ，１３ｑ同士間の一方側に対応する位置のみに設けられているため、弾性突部１３ｎ，１３ｎの元の位置への弾性復帰（復元）が確実に行われ、クラッチ機能が十分に発揮される。なお、溝１３ｓが側端部１３ｐ，１３ｑ同士間の両方側に対応する位置に設けられている場合には、応力の分散・開放は成されるが、弾性突部１３ｎ，１３ｎの元の位置への弾性復帰が行われない場合があり、好ましくない。   Here, in the coating material extruding container 100 of the present embodiment, the above-described groove 13s is provided in the base portion 13m that supports the pair of elastic protrusions 13n and 13n at the rear end portion of the coating material support 13. Therefore, the groove 13s disperses and releases the stress to be concentrated at the time of clutching, thereby preventing the coating material support 13 from being damaged (see the crack C generated in the base 3m described with reference to FIG. 9 in the prior art). Has been. Further, the groove 13s is not provided at a position corresponding to both sides between the side end portions 13p and 13q, but is provided only at a position corresponding to one side between the side end portions 13p and 13q. Therefore, the elastic projections 13n and 13n are reliably restored (restored) to their original positions, and the clutch function is sufficiently exhibited. When the groove 13s is provided at a position corresponding to both sides between the side end portions 13p and 13q, the stress is dispersed and released, but the original position of the elastic protrusions 13n and 13n. There is a case where the elastic recovery to is not performed, which is not preferable.

また、本実施形態によれば、溝１３ｓが、軸体部１３ｂも切り欠く構成であるため、応力が一層分散・開放され、塗布材支持体１３の破損が一層防止されている。   Further, according to the present embodiment, since the groove 13s has a structure in which the shaft body portion 13b is also notched, the stress is further dispersed and released, and the coating material support 13 is further prevented from being damaged.

さらに、本実施形態によれば、基部１３ｍの略中央に、前方へ凹む凹部１３ｒを備え、当該凹部１３ｒと溝１３ｓとが連通しているため、応力が一層分散・開放され、塗布材支持体１３の破損が一層防止されている。   Furthermore, according to the present embodiment, the concave portion 13r that is recessed forward is provided in the approximate center of the base portion 13m, and the concave portion 13r and the groove 13s communicate with each other. 13 is further prevented from being damaged.

なお、本実施形態にあっては、移動限を前進限及び後退限の両方としているが、前進限及び後退限の少なくとも一方としても良い。   In the present embodiment, the movement limit is both the forward limit and the backward limit, but may be at least one of the forward limit and the backward limit.

図７は、本発明の他の実施形態に係る塗布材押出容器の要部を示す縦断面図、図８は、図７中の塗布材支持体の背面図である。   FIG. 7 is a longitudinal sectional view showing a main part of a coating material extruding container according to another embodiment of the present invention, and FIG. 8 is a rear view of the coating material support in FIG.

この実施形態が先の実施形態と違う点は、溝１３ｓに代えて、凹部１３ｔを用いた点である。   This embodiment is different from the previous embodiment in that a recess 13t is used instead of the groove 13s.

この凹部１３ｔは、半径方向外側及び後方に開放された凹部であり、先の実施形態の溝１３ｓとほぼ同位置、具体的には、基部１３ｍの所定位置であって、一対の対向する弾性突部１３ｎ，１３ｎの側端部１３ｐ，１３ｑ同士間の一方側に対応する位置に設けられている。   The recessed portion 13t is a recessed portion opened outward and rearward in the radial direction, and is substantially the same position as the groove 13s of the previous embodiment, specifically, a predetermined position of the base portion 13m, and a pair of opposing elastic protrusions. It is provided at a position corresponding to one side between the side end portions 13p, 13q of the portions 13n, 13n.

このように構成された塗布材押出容器であっても、半径方向外側及び後方に開放された凹部１３ｔにより、クラッチ時に集中しようとする応力が分散・開放され、塗布材支持体１３の破損が防止される。また、当該凹部１３ｔは、側端部１３ｐ，１３ｑ同士間の両方側に対応する位置に設けられているのでは無く、側端部１３ｐ，１３ｑ同士間の一方側に対応する位置のみに設けられているため、弾性突部１３ｎ，１３ｎの元の位置への弾性復帰が確実に行われ、クラッチ機能が十分に発揮される。なお、凹部１３ｔが側端部１３ｐ，１３ｑ同士間の両方側に対応する位置に設けられている場合には、応力の分散・開放は成されるが、弾性突部１３ｎ，１３ｎの元の位置への弾性復帰が行われない場合があり、好ましくない。   Even in the coating material extruding container configured in this way, the stress to concentrate at the time of clutching is dispersed and released by the recesses 13t that are opened outward and rearward in the radial direction, thereby preventing the coating material support 13 from being damaged. Is done. The recess 13t is not provided at a position corresponding to both sides between the side end portions 13p and 13q, but is provided only at a position corresponding to one side between the side end portions 13p and 13q. Therefore, the elastic projections 13n, 13n are reliably restored to their original positions, and the clutch function is sufficiently exhibited. When the recess 13t is provided at a position corresponding to both sides between the side end portions 13p and 13q, the stress is dispersed and released, but the original position of the elastic protrusions 13n and 13n. There is a case where the elastic recovery to is not performed, which is not preferable.

なお、凹部１３ｔの半径方向（図７の紙面垂直奥への方向；図８の右方向）の深さを深くし、クラッチ時に集中しようとする応力を一層分散・開放し、塗布材支持体１３の破損を一層防止するようにしても良く、また、先の実施形態と同様に、基部１３ｍの略中央に、前方へ凹む凹部（別の凹部）１３ｒを設け、当該凹部１３ｒと凹部１３ｔとを連通させることで、応力を一層分散・開放し、塗布材支持体１３の破損を一層防止するようにしても良い。   It should be noted that the depth of the recess 13t in the radial direction (in the direction perpendicular to the plane of FIG. 7; the right direction in FIG. 8) is increased to further disperse and release the stress to concentrate during clutching, thereby applying the coating material support 13 In addition, as in the previous embodiment, a recess (another recess) 13r that is recessed forward is provided at the approximate center of the base 13m, and the recess 13r and the recess 13t are provided. By communicating, the stress may be further dispersed and released to further prevent the coating material support 13 from being damaged.
