特許第5229542号公報Japanese Patent No. 5229542

しかしながら、前記従来の塗布容器では、塗布位置に位置する塗布栓の先端部を被塗布部に当接したときに、例えば、塗布栓が計量筒部材に対して傾き、塗布栓の外周面と吐出孔の内周面との間の隙間の大きさが変化すること等により、大量の内容物が不意に吐出孔から被塗布部に流出するおそれがあった。 However, in the conventional coating container, when the tip of the coating plug located at the coating position comes into contact with the coated portion, for example, the coating plug tilts with respect to the measuring cylinder member and discharges from the outer peripheral surface of the coating plug. Due to changes in the size of the gap between the inner peripheral surface of the hole and the like, a large amount of contents may unexpectedly flow out from the discharge hole to the portion to be coated.

本発明は、前述した事情に鑑みてなされたものであって、大量の内容物が不意に吐出孔から被塗布部に流出するのを抑制することを目的とする。 The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to prevent a large amount of contents from unexpectedly flowing out from a discharge hole to a portion to be coated.

前記課題を解決するために、本発明は以下の手段を提案している。
本発明に係る塗布容器は、被塗布部に塗布する内容物が収容される有底筒状の容器本体と、前記容器本体の口部に装着され、前記容器本体内に連通する連通孔が形成された中栓部材と、前記中栓部材との間に、前記連通孔を通して前記容器本体内に連通する計量室を形成するとともに、頂部に前記計量室に連通する吐出孔が形成された計量筒部材と、前記計量室に設けられるとともに、先端部が前記吐出孔から前記計量室の外部に突出される塗布栓と、を備え、前記塗布栓は、前記吐出孔と前記計量室との連通を遮断し、かつ前記計量室と前記連通孔とを連通させる計量位置と、前記計量位置よりも容器軸方向に沿う前記容器本体の底部側に位置するとともに、前記計量室と前記連通孔との連通を遮断し、かつ前記吐出孔と前記計量室とを連通させる塗布位置と、の間を容器軸方向に移動自在に配設され、前記塗布栓の外周面において、塗布位置に位置したときに前記吐出孔の内側に位置する部分、および前記吐出孔の内周面は、互いに当接するとともに、これらの塗布栓の外周面、および前記吐出孔の内周面のうちのいずれか一方には、容器軸に対して傾斜する方向に延び、前記計量室内と容器外部とを連通する傾斜溝が形成され、前記傾斜溝は、容器軸回りに複数周にわたって延びていることを特徴とする。
In order to solve the above problems, the present invention proposes the following means.
The coating container according to the present invention has a bottomed tubular container body for accommodating the contents to be applied to the coated portion and a communication hole which is attached to the mouth of the container body and communicates with the inside of the container body. A measuring cylinder in which a measuring chamber communicating with the inside of the container body is formed between the inner plug member and the inner plug member, and a discharge hole communicating with the measuring chamber is formed at the top. The member is provided with a coating plug provided in the measuring chamber and a tip portion thereof protrudes from the discharge hole to the outside of the measuring chamber, and the coating plug provides communication between the discharge hole and the measuring chamber. A measuring position that shuts off and communicates the measuring chamber and the communication hole, and is located on the bottom side of the container body along the container axial direction from the measuring position, and also communicates between the measuring chamber and the communication hole. Is arranged so as to be movable in the container axial direction between the coating position for communicating the discharge hole and the measuring chamber, and when the coating position is located on the outer peripheral surface of the coating plug. The portion located inside the discharge hole and the inner peripheral surface of the discharge hole are in contact with each other, and one of the outer peripheral surface of these coating plugs and the inner peripheral surface of the discharge hole is in contact with each other. An inclined groove extending in a direction inclined with respect to the container axis and communicating the measuring chamber with the outside of the container is formed, and the inclined groove extends over a plurality of circumferences around the container axis .

この発明によれば、塗布栓の外周面、および吐出孔の内周面のうちのいずれか一方に、容器軸に対して傾斜する方向に延び、計量室内と容器外部とを連通する傾斜溝が形成されているので、計量室内の内容物を、傾斜溝を通して被塗布部に吐出するときに、容器軸方向に直進させず容器軸に対して傾斜する向きに迂回させることが可能になり、吐出孔から吐出される内容物の勢いが抑えられ、大量の内容物が不意に吐出孔から被塗布部に流出するのを抑えることができる。
しかも、塗布栓の外周面において、塗布位置に位置したときに吐出孔の内側に位置する部分、および吐出孔の内周面が、互いに当接若しくは近接しているので、塗布位置に位置する塗布栓に、塗布栓を計量筒部材に対して径方向に位置ずれさせる外力が加えられても、塗布栓の外周面、および吐出孔の内周面を互いに当接させることができる。したがって、塗布位置に位置する塗布栓の先端部を被塗布部に当接したときに、塗布栓が計量筒部材に対して傾くのを抑制することが可能になり、大量の内容物が不意に吐出孔から被塗布部に流出するのを確実に抑えることができる。
According to the present invention, an inclined groove extending in a direction inclined with respect to the container axis and communicating the measuring chamber and the outside of the container is provided on either the outer peripheral surface of the coating plug or the inner peripheral surface of the discharge hole. Since it is formed, when the contents in the measuring chamber are discharged to the coated portion through the inclined groove, the contents can be detoured in a direction inclined with respect to the container axis without going straight in the container axis direction, and the discharge can be made. The momentum of the contents discharged from the holes can be suppressed, and a large amount of contents can be prevented from unexpectedly flowing out from the discharge holes to the portion to be coated.
Moreover, on the outer peripheral surface of the coating plug, the portion located inside the discharge hole when it is located at the coating position and the inner peripheral surface of the discharge hole are in contact with or close to each other, so that the coating is located at the coating position. Even if an external force that causes the coating plug to be displaced in the radial direction with respect to the measuring cylinder member is applied to the plug, the outer peripheral surface of the coating plug and the inner peripheral surface of the discharge hole can be brought into contact with each other. Therefore, when the tip of the coating plug located at the coating position comes into contact with the portion to be coated, it is possible to prevent the coating plug from tilting with respect to the measuring cylinder member, and a large amount of contents are unexpectedly formed. It is possible to reliably suppress the outflow from the discharge hole to the portion to be coated.

傾斜溝が、容器軸回りに複数周にわたって延びているので、吐出孔から吐出される内容物の勢いを確実に抑えることができる。 Since the inclined groove extends over a plurality of circumferences around the container axis, the momentum of the contents discharged from the discharge hole can be reliably suppressed.

本発明によれば、大量の内容物が不意に吐出孔から被塗布部に流出するのを抑制することができる。 According to the present invention, it is possible to prevent a large amount of contents from unexpectedly flowing out from the discharge hole to the portion to be coated.

塗布栓9は、吐出孔8と計量室6との連通を遮断し、かつ計量室6と連通孔5とを連通させる計量位置(例えば図3に示す状態)と、計量位置よりも下側(容器軸方向に沿う容器本体の底部側)に位置するとともに、計量室6と連通孔5との連通を遮断し、かつ吐出孔8と計量室6とを連通させる(ここでいう「連通させる」とは、「連通する、または連通可能な状態とする」の両方の意味を含む)塗布位置(例えば図1、図2、図4に示す状態)と、の間を容器軸O方向(上下方向)に移動自在に配設されている。 The coating plug 9 cuts off the communication between the discharge hole 8 and the measuring chamber 6 and communicates the measuring chamber 6 with the communication hole 5 (for example, the state shown in FIG. 3) and the lower side than the measuring position (for example, the state shown in FIG. 3). It is located on the bottom side of the container body along the container axis direction), blocks the communication between the measuring chamber 6 and the communication hole 5, and communicates the discharge hole 8 and the measuring chamber 6 (“communication” here. Means both "communicate or enable communication") between the coating position (for example, the state shown in FIGS. 1, 2, and 4) and the container axis O direction (vertical direction). ) Is movably arranged.

塗布栓9は、計量筒部材7内に配設された有頂筒状のシール筒24と、シール筒24の天壁から下方に向けて延び、シール筒24の周壁により径方向の外側から囲繞された外挿筒25と、シール筒24の天壁に立設された筒状の先端部26と、を有する。シール筒24、外挿筒25および先端部26は、容器軸Oと同軸に配置されるとともに、一体に形成されている。 The coating stopper 9 extends downward from the ridged cylinder-shaped seal cylinder 24 arranged in the measuring cylinder member 7 and the top wall of the seal cylinder 24, and is surrounded from the outside in the radial direction by the peripheral wall of the seal cylinder 24. It has an extrapolated cylinder 25 and a tubular tip portion 26 erected on the top wall of the seal cylinder 24. The seal cylinder 24, the extrapolation cylinder 25, and the tip portion 26 are arranged coaxially with the container shaft O and are integrally formed.

シール筒24の上部は、図3に示すように、塗布栓9が計量位置に位置するときに、吐出孔8の内側に摺動自在に嵌合しており、吐出孔8と計量室6との連通を遮断する。シール筒24の下端部は、塗布栓9が、図2および図4に示すように塗布位置に位置するときに、シリンダ筒12の内側に摺動自在に嵌合している。図示の例では、シール筒24のうち、下端部の厚さは、他の部分の厚さより薄くなっている。
このようなシール筒24の下端部は、塗布位置に位置するときに、シリンダ筒12内に嵌合し計量室6と連通孔5との連通を遮断する一方、計量位置に位置するときに、シリンダ筒12内から上方に離脱し計量室6と連通孔5とを連通させる。
As shown in FIG. 3, the upper portion of the seal cylinder 24 is slidably fitted inside the discharge hole 8 when the coating plug 9 is located at the measuring position, and the discharge hole 8 and the measuring chamber 6 are fitted together. Block communication. The lower end of the seal cylinder 24 is slidably fitted inside the cylinder cylinder 12 when the coating stopper 9 is located at the coating position as shown in FIGS. 2 and 4. In the illustrated example, the thickness of the lower end portion of the seal cylinder 24 is thinner than the thickness of the other portion.
When the lower end portion of such a seal cylinder 24 is positioned at the coating position, it fits inside the cylinder cylinder 12 and blocks communication between the measuring chamber 6 and the communication hole 5, while when it is located at the measuring position. It separates upward from the inside of the cylinder cylinder 12 and communicates the measuring chamber 6 with the communication hole 5.

塗布栓9は、径方向の外側に向けて突出するストッパー段部24cを備える。ストッパー段部24cは、シール筒24の外周面における容器軸O方向の中間部分に形成されている。ストッパー段部24cは、周方向に沿って延びる環状に形成されている。ストッパー段部24cは、図3に示すように、塗布栓9が計量位置に位置するときに、計量筒部材7内における吐出孔8の開口周縁部に対して、下側から当接可能である。図示の例では、ストッパー段部24cは、計量筒部材7のうち連結筒部20の天壁の内周縁部に対して、その下側から当接可能となっている。 The coating plug 9 includes a stopper step portion 24c that projects outward in the radial direction. The stopper step portion 24c is formed at an intermediate portion in the container axis O direction on the outer peripheral surface of the seal cylinder 24. The stopper step portion 24c is formed in an annular shape extending along the circumferential direction. As shown in FIG. 3, the stopper step portion 24c can come into contact with the opening peripheral portion of the discharge hole 8 in the measuring cylinder member 7 from the lower side when the coating plug 9 is located at the measuring position. .. In the illustrated example, the stopper step portion 24c can come into contact with the inner peripheral edge portion of the top wall of the connecting cylinder portion 20 of the measuring cylinder member 7 from below.

塗布栓9が計量位置に位置した状態では、塗布栓9のストッパー段部24cが、計量筒部材7における吐出孔8の開口周縁部にその下側から当接することで、たとえ計量室6に対して塗布栓9を上側へ移動させる向きの外力が作用した場合でも、計量位置に位置した塗布栓9がそれ以上に上側に向けて移動することが規制されている。
ここで、シール筒24の上部における外周面には、径方向の外側に向けて突出するとともに周方向に延びる環状または円弧状の第1係合突部24aが形成されている。この第1係合突部24aは、塗布栓9が塗布位置から計量位置に移動したときに、吐出孔8の内周面に形成された第2係合突部8aを上方に乗り越え、第2係合突部8aに第1係合突部24aの下側から係合する。なお、第1係合突部24aおよび第2係合突部8aは、互いに全周にわたって連続して係合しなくてもよい。
In the state where the coating plug 9 is located at the measuring position, the stopper step portion 24c of the coating plug 9 abuts on the peripheral edge of the opening of the discharge hole 8 in the measuring cylinder member 7 from below, so that even with respect to the measuring chamber 6. Even when an external force is applied to move the coating plug 9 upward, the coating plug 9 located at the weighing position is restricted from moving further upward.
Here, an annular or arcuate first engaging protrusion 24a is formed on the outer peripheral surface of the upper portion of the seal cylinder 24 so as to project outward in the radial direction and extend in the circumferential direction. When the coating plug 9 moves from the coating position to the measuring position, the first engaging protrusion 24a overcomes the second engaging protrusion 8a formed on the inner peripheral surface of the discharge hole 8 upward and is second. It engages with the engaging protrusion 8a from below the first engaging protrusion 24a. The first engaging protrusion 24a and the second engaging protrusion 8a do not have to be continuously engaged with each other over the entire circumference.

外挿筒25は、中栓部材4の案内軸11aに上下動自在に外挿されている。図示の例では、外挿筒25は、中栓部材4の案内軸11aに非接触状態で上下動する。これにより、塗布栓9を円滑に上下動させることができる。また、外挿筒25の下端開口縁は、シール筒24の下端開口縁よりも下側に位置している。 The extrapolation cylinder 25 is extrapolated to the guide shaft 11a of the inner plug member 4 so as to be vertically movable. In the illustrated example, the extrapolation cylinder 25 moves up and down in a non-contact state with the guide shaft 11a of the inner plug member 4. As a result, the coating plug 9 can be smoothly moved up and down. Further, the lower end opening edge of the extrapolation cylinder 25 is located below the lower end opening edge of the seal cylinder 24.

図2に示すように、塗布栓9が塗布位置に位置した状態で、外挿筒25の下端開口縁は、支持体11の規制部11bの上端縁と当接し、支持体11の規制部11bに下側から支持されている。このとき、支持体11の案内軸11aの上端縁と、シール筒24の天壁と、の間には、容器軸O方向の隙間が設けられている。なおこれに代えて、案内軸11aの上端縁、およびシール筒24の天壁を互いに当接させて、塗布栓9のこれ以上の下降移動を規制してもよい。 As shown in FIG. 2, with the coating plug 9 positioned at the coating position, the lower end opening edge of the extrapolation cylinder 25 abuts on the upper end edge of the restricting portion 11b of the support 11, and the restricting portion 11b of the support 11 b. It is supported from below. At this time, a gap in the container axis O direction is provided between the upper end edge of the guide shaft 11a of the support 11 and the top wall of the seal cylinder 24. Instead of this, the upper end edge of the guide shaft 11a and the top wall of the seal cylinder 24 may be brought into contact with each other to restrict further downward movement of the coating plug 9.

塗布栓9が塗布位置に位置した状態で、塗布栓9の先端部26は、計量筒部材7の頂部19内に配設されている。先端部26の外径は、塗布栓9が計量位置に位置するときに、吐出孔8の内側に嵌合したシール筒24の上部の外径より小さい。
なお、先端部26の外径をシール筒24の上部の外径と同じにしてもよい。また、先端部26の外径を、下方から上方に向かうに従い漸次、大きくしてもよいし、小さくしてもよい。
塗布栓9が塗布位置に位置した状態で、シール筒24のうち、第1係合突部24aより上方に位置する上端部、および先端部26それぞれの外周面と、吐出孔8の内周面と、の間に、内容物が流通可能な隙間が設けられている。そして、この隙間を通して、計量室6内と容器外部とが連通されている。
なお、塗布栓9が塗布位置に位置した状態で、塗布栓9の先端部26の外周面と、吐出孔8の内周面と、を互いに当接させてもよい。
先端部26の上端部における内周面には、径方向の内側に向けて突出するとともに周方向に延びる環状または円弧状の被係合部26aが形成されている。
The tip portion 26 of the coating plug 9 is arranged in the top portion 19 of the measuring cylinder member 7 with the coating plug 9 positioned at the coating position. The outer diameter of the tip portion 26 is smaller than the outer diameter of the upper part of the seal cylinder 24 fitted inside the discharge hole 8 when the coating plug 9 is located at the measuring position.
The outer diameter of the tip portion 26 may be the same as the outer diameter of the upper portion of the seal cylinder 24. Further, the outer diameter of the tip portion 26 may be gradually increased or decreased from the lower side to the upper side.
With the coating plug 9 located at the coating position, the outer peripheral surface of each of the upper end portion and the tip portion 26 located above the first engaging protrusion 24a and the inner peripheral surface of the discharge hole 8 of the seal cylinder 24. There is a gap between the and, where the contents can be distributed. Then, the inside of the measuring chamber 6 and the outside of the container are communicated with each other through this gap.
In the state where the coating plug 9 is located at the coating position, the outer peripheral surface of the tip portion 26 of the coating plug 9 and the inner peripheral surface of the discharge hole 8 may be brought into contact with each other.
An annular or arcuate engaged portion 26a is formed on the inner peripheral surface of the upper end portion of the tip portion 26 so as to project inward in the radial direction and extend in the circumferential direction.

塗布容器1は、容器本体2の口部3に着脱自在に装着されて吐出孔8および塗布栓9の先端部26を覆うキャップ体10を備える。
キャップ体10は、有頂筒状をなしており、その周壁の下部における内周面に、口部3の雄ねじ部に螺着する雌ねじ部が形成されている。雌ねじ部は、例えば二条ねじであってもよい。
なお、キャップ体10が、口部3に着脱可能に螺着されるのに代えて例えば、キャップ体10の平滑な内周面に、口部3の平滑な外周面を着脱可能に嵌合したり、あるいはキャップ体10が口部3に着脱可能にアンダーカット嵌合したりする等、適宜変更してもよい。また、キャップ体10を、口部3に装着するのに代えて例えば、計量筒部材7に装着してもよい。
The coating container 1 includes a cap body 10 that is detachably attached to the mouth portion 3 of the container body 2 and covers the discharge hole 8 and the tip portion 26 of the coating plug 9.
The cap body 10 has a ridged cylinder shape, and a female screw portion screwed to the male screw portion of the mouth portion 3 is formed on the inner peripheral surface at the lower portion of the peripheral wall thereof. The female thread portion may be, for example, a double thread.
Instead of the cap body 10 being detachably screwed to the mouth portion 3, for example, the smooth outer peripheral surface of the mouth portion 3 is detachably fitted to the smooth inner peripheral surface of the cap body 10. Alternatively, the cap body 10 may be detachably fitted to the mouth portion 3 undercut, and the like may be appropriately changed. Further, the cap body 10 may be attached to, for example, the measuring cylinder member 7 instead of being attached to the mouth portion 3.

キャップ体10の天壁には、下方に向けて突出するとともに、下端部が、塗布位置に位置する塗布栓9の先端部26内に着脱自在に嵌合された引き上げ筒31が形成されている。引き上げ筒31の外周面には、径方向の外側に向けて突出するとともに周方向に延びる環状または円弧状の引き上げ突起31aが形成されている。引き上げ突起31aは、塗布栓9の先端部26の被係合部26aにアンダーカット嵌合されており、キャップ体10の、口部3および計量筒部材7に対する上昇移動に伴い、塗布栓9が引き上げられて塗布位置から計量位置に移動する。 On the top wall of the cap body 10, a pull-up cylinder 31 is formed so as to project downward and the lower end thereof is detachably fitted in the tip portion 26 of the coating plug 9 located at the coating position. .. An annular or arcuate pulling protrusion 31a is formed on the outer peripheral surface of the pulling cylinder 31 so as to project outward in the radial direction and extend in the circumferential direction. The pull-up protrusion 31a is undercut fitted to the engaged portion 26a of the tip portion 26 of the coating plug 9, and the coating plug 9 is moved as the cap body 10 moves upward with respect to the mouth portion 3 and the measuring cylinder member 7. It is pulled up and moves from the coating position to the weighing position.

ここで、キャップ体10の引き上げ突起31aが、塗布栓9の被係合部26aから外れるときには、計量位置に位置する塗布栓9のストッパー段部24cが、計量筒部材7における吐出孔8の開口周縁部にその下側から当接することで、塗布栓9がそれ以上に上側に向けて移動することが規制された状態となる。したがって、キャップ体10の引き上げ突起31aが、塗布栓9の被係合部26aから外れる際、塗布栓9には下方に向けた弾性反発力が生ずることとなる。
しかしながら、前述したように、塗布栓9の第1係合突部24aが、計量筒部材7の第2係合突部8aに、第1係合突部24aの下側から係合しているので、塗布栓9の計量位置から下方に向けた移動を規制することができる。
Here, when the pulling protrusion 31a of the cap body 10 is disengaged from the engaged portion 26a of the coating plug 9, the stopper step portion 24c of the coating plug 9 located at the measuring position opens the discharge hole 8 in the measuring cylinder member 7. By contacting the peripheral edge portion from the lower side, the coating plug 9 is restricted from moving further upward. Therefore, when the pulling protrusion 31a of the cap body 10 is disengaged from the engaged portion 26a of the coating plug 9, the coating plug 9 is subjected to an elastic repulsive force downward.
However, as described above, the first engaging protrusion 24a of the coating plug 9 is engaged with the second engaging protrusion 8a of the measuring cylinder member 7 from the lower side of the first engaging protrusion 24a. Therefore, it is possible to restrict the downward movement of the coating plug 9 from the weighing position.

キャップ体10の天壁には、下方に向けて突出し、計量筒部材7の頂部19に着脱自在に外嵌された外嵌筒28が形成されている。
キャップ体10は、計量筒部材7の頂部19にその上方から当接する当接部27を備える。当接部27は、キャップ体10の天壁から下方に向けて突出している。当接部27は、キャップ体10の天壁において、外嵌筒28の内側に位置する部分に配置されている。当接部27は、周方向に間隔をあけて複数配置され、外嵌筒28の内周面と一体に形成されている。当接部27の下端縁は、外嵌筒28の下端開口縁より上方に位置している。当接部27の下端縁が、計量筒部材7の頂部19の上端開口縁に当接している。なお、当接部27は環状に形成されてもよい。
The top wall of the cap body 10 is formed with an outer fitting cylinder 28 that protrudes downward and is detachably fitted to the top 19 of the measuring cylinder member 7.
The cap body 10 includes a contact portion 27 that abuts on the top portion 19 of the measuring cylinder member 7 from above. The contact portion 27 projects downward from the top wall of the cap body 10. The contact portion 27 is arranged on the top wall of the cap body 10 at a portion located inside the outer fitting cylinder 28. A plurality of abutting portions 27 are arranged at intervals in the circumferential direction, and are integrally formed with the inner peripheral surface of the outer fitting cylinder 28. The lower end edge of the contact portion 27 is located above the lower end opening edge of the outer fitting cylinder 28. The lower end edge of the contact portion 27 is in contact with the upper end opening edge of the top portion 19 of the measuring cylinder member 7. The contact portion 27 may be formed in an annular shape.

キャップ体10の周壁の下端部の内周面には、周方向を向く壁面を備えた段部32が形成されている。キャップ体10が容器本体2の口部3に装着された状態において、段部32は、容器本体2の回り止めリブ3bに周方向から当接可能とされている。段部32が回り止めリブ3bに周方向から当接することで、キャップ体10が口部3に過度に締め込まれることが規制される。 A stepped portion 32 having a wall surface facing in the circumferential direction is formed on the inner peripheral surface of the lower end portion of the peripheral wall of the cap body 10. In a state where the cap body 10 is attached to the mouth portion 3 of the container main body 2, the step portion 32 can be brought into contact with the detent rib 3b of the container main body 2 from the circumferential direction. When the step portion 32 comes into contact with the detent rib 3b from the circumferential direction, the cap body 10 is restricted from being excessively tightened to the mouth portion 3.

そして、本実施形態では、塗布栓9の外周面において、塗布位置に位置したときに吐出孔8の内側に位置する部分、および吐出孔8の内周面は、互いに当接若しくは近接するとともに、この塗布栓9の外周面に、容器軸Oに対して傾斜する方向に延び、計量室6内と容器外部とを連通する傾斜溝21が形成されている。傾斜溝21は、容器軸O回りに複数周にわたって延びている。
図示の例では、傾斜溝21は、塗布栓9の先端部26の外周面に形成されている。なお、容器軸O回りに螺旋状に延びる条状の突起を配設し、容器軸O方向で隣り合う突起同士の間の隙間を傾斜溝21としてもよい。
Then, in the present embodiment, on the outer peripheral surface of the coating plug 9, the portion located inside the discharge hole 8 when it is located at the coating position and the inner peripheral surface of the discharge hole 8 are in contact with each other or close to each other and are close to each other. An inclined groove 21 is formed on the outer peripheral surface of the coating plug 9 so as to extend in a direction in which it is inclined with respect to the container shaft O and communicate the inside of the measuring chamber 6 with the outside of the container. The inclined groove 21 extends over a plurality of circumferences around the container axis O.
In the illustrated example, the inclined groove 21 is formed on the outer peripheral surface of the tip portion 26 of the coating plug 9. It should be noted that a strip-shaped protrusion extending spirally around the container shaft O may be arranged, and the gap between the protrusions adjacent to each other in the container shaft O direction may be used as the inclined groove 21.

塗布容器1は、中栓部材4、計量筒部材7、および塗布栓9が組み立てられてなる計量塗布具を、内容物の充填された容器本体2の口部3に装着した後に、キャップ体10を口部3に螺着することで形成される。 The coating container 1 has a cap body 10 after the measuring applicator in which the inner plug member 4, the measuring cylinder member 7, and the coating plug 9 are assembled is attached to the mouth portion 3 of the container body 2 filled with the contents. Is formed by screwing to the mouth portion 3.

以下、本実施形態の塗布容器1の作用について説明する。 Hereinafter, the operation of the coating container 1 of the present embodiment will be described.

図2に示すように、塗布容器1の使用前では、塗布栓9のシール筒24の下端部がシリンダ筒12の周壁の内側に嵌合して、計量室6と連通孔5との連通が遮断されている。
容器本体2内の内容物を被塗布部Sに塗布するには、まず、キャップ体10を上側へ移動させて容器本体2の口部3から離脱させ、吐出孔8および塗布栓9の先端部26を容器外部に露出させる。ここで、キャップ体10が離脱される際には、引き上げ筒31の引き上げ突起31aと、塗布栓9の先端部26の被係合部26aと、が互いに容器軸O方向に係合することで、キャップ体10により塗布栓9が引き上げられて計量位置に移動する。この際、口部3の雄ねじ部、およびキャップ体10の雌ねじ部は、二条ねじであるため、一条ねじである構成と比較して、ねじのリードが大きくなる。このため、キャップ体10の周方向の回転量に対する容器軸O方向の変位量を大きくすることができる。これにより、塗布栓9を速やかに上側に移動させることができるとともに、キャップ体10を容器本体2の口部3から速やかに離脱させることができる。
As shown in FIG. 2, before using the coating container 1, the lower end of the sealing cylinder 24 of the coating plug 9 fits inside the peripheral wall of the cylinder cylinder 12, and the measuring chamber 6 and the communication hole 5 communicate with each other. It is blocked.
In order to apply the contents in the container body 2 to the coated portion S, first, the cap body 10 is moved upward to be separated from the mouth portion 3 of the container body 2, and the tip portions of the discharge hole 8 and the coating plug 9 are applied. 26 is exposed to the outside of the container. Here, when the cap body 10 is disengaged, the pulling protrusion 31a of the pulling cylinder 31 and the engaged portion 26a of the tip portion 26 of the coating plug 9 engage with each other in the container shaft O direction. , The coating plug 9 is pulled up by the cap body 10 and moved to the weighing position. At this time, since the male threaded portion of the mouth portion 3 and the female threaded portion of the cap body 10 are double-threaded threads, the lead of the screw is larger than that of the single-threaded thread. Therefore, the amount of displacement in the container axis O direction with respect to the amount of rotation of the cap body 10 in the circumferential direction can be increased. As a result, the coating stopper 9 can be quickly moved upward, and the cap body 10 can be quickly detached from the mouth portion 3 of the container body 2.

図3に示すように、塗布栓9が計量位置へ移動させられると、塗布栓9のシール筒24の上部が吐出孔8の内側に嵌合し、塗布栓9のストッパー段部24cが計量筒部材7の連結筒部20の天壁(吐出孔8の開口周縁部)に当接し、また、塗布栓9の第1係合突部24aが、計量筒部材7の第2係合突部8aを上方に乗り越え、第1係合突部24aが、第2係合突部8aに第1係合突部24aの下側から係合する。この際、吐出孔8と計量室6との連通が遮断されている。この状態から、さらに容器本体2の口部3に対してキャップ体10が上側へ移動することで、キャップ体10の引き上げ筒31の引き上げ突起31aが、塗布栓9の先端部26の被係合部26aを上方に乗り越えて、キャップ体10が容器本体2および塗布栓9から取り外される。 As shown in FIG. 3, when the coating plug 9 is moved to the measuring position, the upper part of the seal cylinder 24 of the coating plug 9 fits inside the discharge hole 8, and the stopper step portion 24c of the coating plug 9 is the measuring cylinder. The first engaging protrusion 24a of the coating plug 9 abuts on the top wall (opening peripheral edge of the discharge hole 8) of the connecting cylinder portion 20 of the member 7, and the second engaging protrusion 8a of the measuring cylinder member 7 The first engaging protrusion 24a engages with the second engaging protrusion 8a from below the first engaging protrusion 24a. At this time, the communication between the discharge hole 8 and the measuring chamber 6 is cut off. From this state, the cap body 10 is further moved upward with respect to the mouth portion 3 of the container body 2, so that the pulling protrusion 31a of the pulling cylinder 31 of the cap body 10 is engaged with the tip portion 26 of the coating plug 9. The cap body 10 is removed from the container body 2 and the coating plug 9 by overcoming the portion 26a upward.

次いで、塗布栓9が計量位置に位置した状態で、塗布容器1を倒立姿勢にすることで、容器本体2内の内容物を連通孔5を通して計量室6内に流入させる。この際、塗布栓9により吐出孔8と計量室6との連通が遮断されているので、計量室6に所定量の内容物が計量される。
次いで、図4に示すように、計量位置に位置する塗布栓9の先端部26を、被塗布部Sに押し付けると、塗布栓9は、塗布位置に向けて移動する。この過程において、計量室6と容器外部とが、塗布栓9の先端部26の外周面に形成された傾斜溝21を通して連通するとともに、外挿筒25が中栓部材4の規制部11bに突き当たり、また、シール筒24の下端部がシリンダ筒12の周壁の内側に嵌合する。
これにより、塗布容器1は、計量室6と連通孔5との連通が遮断されるとともに、吐出孔8と計量室6とが連通し、塗布栓9の傾斜溝21を通して、計量室6の内容物を被塗布部Sに塗布することができる。
Next, with the coating plug 9 positioned at the measuring position, the coating container 1 is placed in an inverted position so that the contents in the container body 2 flow into the measuring chamber 6 through the communication hole 5. At this time, since the communication between the discharge hole 8 and the measuring chamber 6 is blocked by the coating plug 9, a predetermined amount of contents are weighed in the measuring chamber 6.
Next, as shown in FIG. 4, when the tip portion 26 of the coating plug 9 located at the measuring position is pressed against the coated portion S, the coating plug 9 moves toward the coating position. In this process, the measuring chamber 6 and the outside of the container communicate with each other through the inclined groove 21 formed on the outer peripheral surface of the tip portion 26 of the coating plug 9, and the extrapolation cylinder 25 abuts on the regulating portion 11b of the inner plug member 4. Further, the lower end portion of the seal cylinder 24 fits inside the peripheral wall of the cylinder cylinder 12.
As a result, in the coating container 1, the communication between the measuring chamber 6 and the communication hole 5 is cut off, the discharge hole 8 and the measuring chamber 6 communicate with each other, and the contents of the measuring chamber 6 pass through the inclined groove 21 of the coating plug 9. An object can be applied to the coated portion S.

そして使用後(塗布後)は、キャップ体10の引き上げ筒31の下端部を、塗布栓9の先端部26内に嵌合させつつ、引き上げ筒31の引き上げ突起31aを、先端部26の被係合部26aに被係合部26aの上方から当接させた状態で、キャップ体10の雌ねじ部を容器本体2の口部3の雄ねじ部に螺合することによって、引き上げ突起31aを、被係合部26aを下方に乗り越えさせるとともに、キャップ体10を容器本体2の口部3に装着する。 After use (after coating), the lower end of the pulling cylinder 31 of the cap body 10 is fitted into the tip 26 of the coating plug 9, and the pulling protrusion 31a of the pulling cylinder 31 is engaged with the tip 26. The pull-up protrusion 31a is engaged by screwing the female threaded portion of the cap body 10 into the male threaded portion of the mouth portion 3 of the container body 2 in a state where the cap body 10 is in contact with the mating portion 26a from above the engaged portion 26a. The joint portion 26a is made to ride downward, and the cap body 10 is attached to the mouth portion 3 of the container body 2.

以上説明したように、本実施形態による塗布容器1によれば、塗布栓9の外周面に、容器軸Oに対して傾斜する方向に延び、計量室6内と容器外部とを連通する傾斜溝21が形成されているので、計量室6内の内容物を、傾斜溝21を通して被塗布部Sに吐出するときに、容器軸O方向に直進させず容器軸Oに対して傾斜する向きに迂回させることが可能になり、吐出孔8から吐出される内容物の勢いが抑えられ、大量の内容物が不意に吐出孔8から被塗布部Sに流出するのを抑えることができる。 As described above, according to the coating container 1 according to the present embodiment, an inclined groove extending in a direction in which the outer peripheral surface of the coating plug 9 is inclined with respect to the container shaft O and communicating the inside of the measuring chamber 6 and the outside of the container. Since the 21 is formed, when the contents in the measuring chamber 6 are discharged to the coated portion S through the inclined groove 21, the contents do not go straight in the container axis O direction but detour in a direction inclined with respect to the container axis O. It is possible to suppress the momentum of the contents discharged from the discharge hole 8 and prevent a large amount of contents from unexpectedly flowing out from the discharge hole 8 to the coated portion S.

しかも、塗布栓9の外周面において、塗布位置に位置したときに吐出孔8の内側に位置する部分、および吐出孔8の内周面が、互いに当接若しくは近接しているので、塗布位置に位置する塗布栓9に、塗布栓9を計量筒部材7に対して径方向に位置ずれさせる外力が加えられても、塗布栓9の外周面、および吐出孔8の内周面を互いに当接させることができる。したがって、塗布位置に位置する塗布栓9の先端部26を被塗布部Sに当接したときに、塗布栓9が計量筒部材7に対して傾くのを抑制することが可能になり、大量の内容物が不意に吐出孔8から被塗布部Sに流出するのを確実に抑えることができる。
また、傾斜溝21が、容器軸O回りに複数周にわたって延びているので、吐出孔8から吐出される内容物の勢いを確実に抑えることができる。
Moreover, on the outer peripheral surface of the coating plug 9, the portion located inside the discharge hole 8 when it is located at the coating position and the inner peripheral surface of the discharge hole 8 are in contact with each other or close to each other, so that the coating position is reached. Even if an external force that causes the coating plug 9 to be displaced in the radial direction with respect to the measuring cylinder member 7 is applied to the positioned coating plug 9, the outer peripheral surface of the coating plug 9 and the inner peripheral surface of the discharge hole 8 are in contact with each other. Can be made to. Therefore, when the tip portion 26 of the coating plug 9 located at the coating position comes into contact with the coated portion S, it is possible to prevent the coating plug 9 from tilting with respect to the measuring cylinder member 7, resulting in a large amount. It is possible to reliably prevent the contents from unexpectedly flowing out from the discharge hole 8 to the portion S to be coated.
Further, since the inclined groove 21 extends over a plurality of circumferences around the container shaft O, the momentum of the contents discharged from the discharge hole 8 can be reliably suppressed.

また、前記実施形態では、傾斜溝21を、塗布栓9の外周面において、塗布位置に位置したときに吐出孔8の内側に位置する部分に形成したが、傾斜溝21は、吐出孔8の内周面に形成してもよい。
また、前記実施形態では、傾斜溝21として、周方向に複数周延びた一条溝の構成を示したが、例えば、容器軸Oに対して傾斜する方向に真直ぐ延びる構成、または、容器軸O方向に屈曲しながら周方向に延びる構成、または多条溝等を採用してもよい。
For example, by forming at least a part of the coating plug 9 with a soft material or the like, it is possible to make the coating feel of the coating plug 9 comfortable and comfortable with less irritation.
Further, in the above embodiment, the inclined groove 21 is formed on the outer peripheral surface of the coating plug 9 at a portion located inside the discharge hole 8 when it is located at the coating position, but the inclined groove 21 is formed in the discharge hole 8. It may be formed on the inner peripheral surface.
Further, in the above-described embodiment, the configuration of the single groove extending in the circumferential direction is shown as the inclined groove 21, but for example, the configuration extends straight in the direction of inclination with respect to the container shaft O, or the container shaft O direction. A configuration that extends in the circumferential direction while bending, or a multi-row groove or the like may be adopted.

その他、本発明の趣旨に逸脱しない範囲で、前記実施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、前記した変形例を適宜組み合わせてもよい。 In addition, it is appropriately possible to replace the constituent elements in the above-described embodiment with well-known constituent elements without departing from the spirit of the present invention, and the above-mentioned modifications may be appropriately combined.
