Description

本発明は、塗布用充填物を押し出して塗布するための塗布用充填物押出容器に関する。   The present invention relates to a coating filler extrusion container for extruding and coating a coating filler.

従来、容器に内蔵された例えば液状充填物を始めとした塗布用充填物を押し出して使用に供する移動体繰出装置として、塗布用充填物が充填される充填領域を内部に備える本体筒と、この本体筒の後端部に相対回転自在に設けられる操作筒と、を備え、本体筒と操作筒が相対回転されると、本体筒及び操作筒内に収容されている移動体が前進し、この移動体の先端に設けられているピストンが前進することで塗布用充填物が先端側に押し出され、本体筒の先端に装着されている吐出蓋の開口を通して塗布用充填物を被塗布部に塗布することが可能な移動体繰出装置が知られている（例えば、特許文献１参照）。
特開２００４−８９６８７号公報 Conventionally, as a moving body feeding device for extruding a coating filler, such as a liquid filler, contained in a container for use, a main body cylinder having a filling region filled with a coating filler, An operation cylinder provided at the rear end portion of the main body cylinder so as to be relatively rotatable, and when the main body cylinder and the operation cylinder are relatively rotated, the main body cylinder and the movable body accommodated in the operation cylinder move forward. When the piston provided at the tip of the moving body moves forward, the filler for application is pushed out to the tip side, and the filler for application is applied to the part to be coated through the opening of the discharge lid attached to the tip of the main body cylinder. A movable body feeding device that can be used is known (for example, see Patent Document 1).
JP 2004-89687 A

しかしながら、上記装置にあっては、移動体が最大に前進しても、吐出蓋の先端の内側に塗布用充填物の一部が残留して使い残しが生じるため、改善が望まれている。   However, in the above-described apparatus, even if the moving body moves forward to the maximum, a part of the filling for coating remains inside the tip of the discharge lid, resulting in a remaining use.

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、塗布用充填物の使い残しが殆ど無く、経済的な塗布用充填物押出容器を提供することを目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to provide an economical coating filler extruding container with almost no use of the coating filler.

本発明による塗布用充填物押出容器は、容器内の充填領域に充填された塗布用充填物を、容器内に配設された移動体が前進することで、容器先端に設けられた吐出口を通して吐出する塗布用充填物押出容器において、容器先端の吐出口を有する先端部の外面を傾斜面とし、先端部の内面を外面に沿って傾斜する傾斜面として、容器先端内に斜円柱状の空間を設け、移動体の先端に、移動体の最大前進時において内面の傾斜面に当接し当該傾斜面に倣って弾性変形する弾性体を設け、弾性体の非変形時における外形は、移動体の軸を中心として回転対称であることを特徴としている。 The coating filler extruding container according to the present invention allows the coating filler filled in the filling region in the container to advance through the discharge port provided at the tip of the container as the moving body disposed in the container advances. In the dispensing container for coating application to be discharged, the outer surface of the tip portion having the discharge port at the tip of the container is an inclined surface, and the inner surface of the tip portion is an inclined surface that is inclined along the outer surface. An elastic body that abuts the inclined surface of the inner surface at the time of maximum advancement of the moving body and elastically deforms following the inclined surface is provided at the tip of the moving body. It is characterized by being rotationally symmetric about an axis .

このような塗布用充填物押出容器によれば、容器先端の吐出口を有する先端部の外面が傾斜面とされるため、例えば皮膚等の被塗布部に対する塗布が好適に成されると共に、移動体の先端に設けられた弾性体が、移動体が最大に前進すると、容器先端の吐出口を有する先端部の内面の傾斜面に当接し当該傾斜面に倣って弾性変形するため、従来のピストンでは押し出せない略ひずめ形（斜円柱状）の空間（容器先端内の傾斜面を含む空間）に残る塗布用充填物が当該弾性体により殆ど残り無く十分に押し出されて消費されるようになる。   According to such a filling material extruding container for application, since the outer surface of the distal end portion having the discharge port at the distal end of the container is an inclined surface, for example, application to an application portion such as the skin is suitably performed and moved. Since the elastic body provided at the tip of the body contacts the inclined surface of the inner surface of the distal end portion having the discharge port at the distal end of the container and moves elastically following the inclined surface when the moving body advances to the maximum, the conventional piston In this case, the filling material remaining in the substantially distorted (obliquely cylindrical) space (the space including the inclined surface inside the container tip) that cannot be pushed out is almost completely left out by the elastic body and consumed. .

ここで、上記作用を効果的に奏する具体的な構成としては、容器は、互いに回転自在に連結されて移動体を収容する筒状体を備えると共に、これらの筒状体の相対回転による移動体の移動を可能とする雄螺子と雌螺子の螺合部及び移動体の回り止め部を内蔵して成る構成が挙げられる。   Here, as a specific configuration that effectively exhibits the above-described operation, the container includes a cylindrical body that is rotatably connected to each other and accommodates the movable body, and a movable body that is obtained by relative rotation of these cylindrical bodies. The structure which incorporates the screwing part of the male screw and the female screw which enables the movement of this, and the rotation prevention part of a moving body is mentioned.

また、弾性体の内部には、空間が設けられていると、この空間により弾性変形がし易くされ、塗布用充填物が一層十分に押し出されるようになる。   Further, if a space is provided inside the elastic body, the space is easily elastically deformed, and the coating filler is more fully extruded.

また、弾性体がシリコンゴム製であると、上記作用が効果的に奏される。また弾性体の非変形時における外形は、移動体の軸を中心として回転対称であると、塗布用充填物を均等に押圧することができる。また弾性体の非変形時における外形は、釣り鐘形状又は半球状であると好ましい。
Moreover, the said effect | action is show | played effectively as an elastic body is a product made from a silicone rubber. Further, when the outer shape of the elastic body when not deformed is rotationally symmetric about the axis of the moving body, the coating filler can be pressed evenly. The outer shape of the elastic body when not deformed is preferably a bell-shaped or hemispherical shape.

このように本発明による塗布用充填物押出容器によれば、塗布用充填物の使い残しが殆ど無く、経済的な塗布用充填物押出容器を提供することが可能となる。   As described above, according to the filling filler extrusion container for coating according to the present invention, it is possible to provide an economical filling filler extrusion container with little use of the filling filler for coating.

以下、塗布用充填物押出容器１００の前半部を構成する先筒１、及び、移動体６の先端に装着された弾性体９について説明する。先ず、先筒１について詳説する。   Hereinafter, the front tube 1 constituting the front half of the coating filler extruding container 100 and the elastic body 9 attached to the tip of the moving body 6 will be described. First, the leading tube 1 will be described in detail.

先筒１は、塗布用充填物Ｌを収容すると共に、当該塗布用充填物Ｌを使用者による操作に従って先端部から吐出し当該先端部が被塗布部に当てられて塗布に供される。このため、先筒１の材質は、ポリエチレンテレフタレート（ＰＥＴ）やポリプロピレン（ＰＰ）等の射出成形されたプラスチックであることが好ましく、また、透明材が好ましい。このように透明材とした場合には、後述のキャップ７を先筒１に装着した状態でも、キャップ７で覆われずに露出する先筒１の後述する膨出部１ｄを通し外観から、充填された塗布用充填物Ｌの色を確認することができる。   The front tube 1 accommodates the filling material L for application, discharges the filling material L for application from the tip portion according to the operation by the user, and the tip portion is applied to the portion to be coated and used for coating.

弾性体９を装着したピストン８は、その後部側から移動体６の先端部に外挿され、図１及び図２に示すように、その凹部８ｄ及び凸部８ｅが、移動体６の先端部に設けられている環状突部６ｃに係合することで、移動体６に回転自在且つ軸線方向移動不能に装着されている。   The piston 8 to which the elastic body 9 is attached is extrapolated from the rear side to the distal end portion of the movable body 6, and the concave portion 8 d and the convex portion 8 e are formed at the distal end portion of the movable body 6 as shown in FIGS. 1 and 2. By engaging with an annular protrusion 6c provided on the movable body 6, the movable body 6 is mounted so as to be rotatable and immovable in the axial direction.

そして、このように構成された塗布用充填物押出容器１００では、移動体６の最大前進時において、弾性体９が先筒１の先端部の傾斜する内面１ｂに押し当てられるように、寸法、配置等の設定が成されている。   And, in the filling filler extruding container 100 configured in this way, when the movable body 6 is at its maximum advance, the elastic body 9 is pressed against the inclined inner surface 1b of the front end portion of the front tube 1, Settings such as placement are made.

このような塗布用充填物押出容器１００によれば、前述したように、使用者により本体筒２又は先筒１と操作筒３とが移動体６の前進方向に相対回転されると、移動体６がクリック感を伴い前進し、先筒１内に充填されている塗布用充填物Ｌは弾性体９により前方に押し出されて吐出口１ｃから吐出され塗布に供される。   According to the filling filler extruding container 100 for application as described above, when the user rotates the main body cylinder 2 or the front cylinder 1 and the operation cylinder 3 relative to each other in the forward direction of the moving body 6, the moving body 6 advances with a click feeling, and the filling L for application filled in the front tube 1 is pushed forward by the elastic body 9 and discharged from the discharge port 1c for application.

そして、特に本実施形態の塗布用充填物押出容器１００にあっては、図２に示すように、使用者による相対回転により移動体６が最大に前進すると、弾性体９が、先筒１の先端部の傾斜する内面１ｂに当接し当該内面１ｂに倣って弾性変形する。この時、弾性体９内の空間９ｄにより当該弾性体９は一層好適に弾性変形する。そして、このような弾性体９の弾性変形により、従来のピストンでは押し出せない略ひずめ形（斜円柱状）の空間（容器先端内の傾斜面を含む空間）に残る塗布用充填物Ｌが殆ど残り無く十分に押し出されて消費される。このため、塗布用充填物Ｌの使い残しが殆ど無い経済的な塗布用充填物押出容器１００を提供できる。   And especially in the filling filler extruding container 100 of the present embodiment, as shown in FIG. 2, when the movable body 6 moves forward by relative rotation by the user, the elastic body 9 It abuts against the inclined inner surface 1b and elastically deforms following the inner surface 1b. At this time, the elastic body 9 is more preferably elastically deformed by the space 9d in the elastic body 9. Due to such elastic deformation of the elastic body 9, almost no coating filling L remains in a substantially distorted (obliquely cylindrical) space (a space including an inclined surface in the tip of the container) that cannot be pushed out by a conventional piston. It is fully extruded and consumed without remaining. For this reason, it is possible to provide an economical coating filler extrusion container 100 in which the coating filler L is hardly left unusable.

また、本実施形態の塗布用充填物押出容器１００では、弾性体９を弾性変形させ先筒１の先端部の内面１ｂに倣わせることで塗布用充填物Ｌを吐出しているため、たとえ部品にガタや寸法誤差が生じたとしても、弾性体９の弾性変形によりそれらを十分に吸収して内面１ｂに倣わせることが可能であり、塗布用充填物Ｌの十分な取り出しが可能である。また、容器１００の組立時に内面１ｂと弾性体９との厳密な位置合わせは必要でなく、組立作業も簡単になる。更に、弾性体９及びピストン８によりシール性が高められているため、移動体６の押出時における塗布用充填物Ｌの後方への漏れを抑えることができる。   Further, in the filling filler extruding container 100 of the present embodiment, the filling material L is discharged by causing the elastic body 9 to elastically deform and follow the inner surface 1b of the tip portion of the tip tube 1, so that Even if there is a backlash or dimensional error in the part, it is possible to sufficiently absorb the elastic body 9 so as to follow the inner surface 1b by elastic deformation of the elastic body 9, and to sufficiently take out the filling L for coating. is there. Further, when the container 100 is assembled, it is not necessary to strictly align the inner surface 1b and the elastic body 9, and the assembling work is simplified. Furthermore, since the sealing performance is enhanced by the elastic body 9 and the piston 8, it is possible to suppress the backward leakage of the coating filler L when the moving body 6 is pushed out.

以上、本発明をその実施形態に基づき具体的に説明したが、本発明は上記実施形態に限定されるものではなく、例えば、上記実施形態においては、移動体６が前進／後進するようにしているが、クリック機構に代えて、移動体６の前進方向の回転を許容するラチェット機構を用いるようにしても良い。   Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the moving body 6 moves forward / backward. However, instead of the click mechanism, a ratchet mechanism that allows the moving body 6 to rotate in the forward direction may be used.

また、先筒１の傾斜する外面１ａに、細毛等が植設してあっても勿論良い。   Of course, fine hair or the like may be planted on the inclined outer surface 1a of the front tube 1.

また、上記実施形態においては、特に好適であるとして、塗布用充填物押出容器１００の押出機構を螺合機構４ａ，６ａによる回転式としているが、例えばノック式の押出機構等を採用することも可能である。   In the above-described embodiment, the extrusion mechanism of the application filler extruding container 100 is a rotary type by the screwing mechanisms 4a and 6a as being particularly suitable. However, for example, a knock type extrusion mechanism or the like may be employed. Is possible.

なお、上記雄螺子６ａには、間欠的に配される突起群又は螺旋状且つ間欠的に配される突起群であって、螺子山と同様な働きをするものを含み、また、上記雌螺子４ａには、間欠的に配される突起群又は螺旋状且つ間欠的に配される突起群であって、螺子山と同様な働きをするものを含む。   The male screw 6a includes a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently, which functions in the same manner as a screw thread. 4a includes a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently, which functions in the same manner as a screw thread.

また、弾性体９は先端に向けて先細りとされた釣り鐘形状としたが、弾性体９の外形はこれに限られず、半球状等であってもよい。ただし、弾性体９の外形は非変形時において先筒１の内面１ｂに沿って傾斜するものではなく、移動体６の最大前進時において内面１ｂに当接し、弾性変形により初めて傾斜面に倣うものである。なお、塗布用充填物Ｌを均等に押圧する観点からは、弾性体９の非変形時における外形は、上記した釣り鐘形状や半球状のように、移動体６の軸を中心として回転対称であると好ましい。   The elastic body 9 has a bell shape tapered toward the tip, but the outer shape of the elastic body 9 is not limited to this and may be a hemispherical shape. However, the outer shape of the elastic body 9 does not incline along the inner surface 1b of the front tube 1 when not deformed, but comes into contact with the inner surface 1b when the moving body 6 is fully advanced and follows the inclined surface for the first time by elastic deformation. It is. In addition, from the viewpoint of pressing the coating filler L evenly, the outer shape of the elastic body 9 when not deformed is rotationally symmetric about the axis of the moving body 6 like the above-described bell shape or hemispherical shape. And preferred.
