しかし、このような塗布具では、塗布部材をホルダ部材に取り付ける際、塗布部材をホルダ部材に対して上方から押し込むだけでは塗布部材をホルダ部材の装着突部に係止させることができないことがあった。そのため、必要に応じて、塗布部材をホルダ部材の下方から引き込むことによって塗布部材をホルダ部材内の所定位置に配置させると共に装着突部に係止させる必要があった。 However, in such an applicator, when the applicator member is attached to the holder member, the applicator member may not be locked to the mounting protrusion of the holder member simply by pressing the applicator member into the holder member from above. It was. Therefore, if necessary, the application member has to be disposed at a predetermined position in the holder member by pulling the application member from below the holder member and locked to the mounting protrusion.

本発明は、前述の課題に鑑みてなされたもので、塗布部材をホルダ部材に対して容易に装着できる塗布具を提供することを目的とする。 The present invention has been made in view of the above-described problems, and an object thereof is to provide an applicator capable of easily mounting an applicator member on a holder member.

本発明は、上記のような課題を解決するために以下のような手段を採用した。すなわち、本発明の塗布具は、内容物が収容される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装着部材と、前記装着部材に配設され、前記連通孔をその軸線方向に直交する径方向の外側から囲繞する筒状のホルダ部材と、前記ホルダ部材の内側に配設、保持され、内容物を被塗布部に塗布する塗布部材と、を備え、前記ホルダ部材の内周面には、その内側に向けて突出し、前記塗布部材の外周面に形成された環状の係合凹部に嵌合される環状の装着突部が設けられ、前記装着突部には、前記ホルダ部材の軸線回りに周回する周方向の延在を分断する間欠部が形成され、前記装着突部のうち前記間欠部を画成する一対の周端部が、前記ホルダ部材の軸線方向の位置を互いに異ならせて配置されていることを特徴とする。 The present invention employs the following means in order to solve the above problems. That is, the applicator of the present invention is attached to the mouth portion of the container main body in which the contents are stored, and is provided in the mounting member formed with a communication hole communicating with the inside of the container main body. A cylindrical holder member that surrounds the communication hole from the outside in the radial direction orthogonal to the axial direction thereof, and an application member that is disposed and held inside the holder member and applies the contents to the application portion. The inner circumferential surface of the holder member is provided with an annular mounting projection that projects inwardly and is fitted into an annular engaging recess formed on the outer circumferential surface of the application member. The portion is formed with an intermittent portion that divides the circumferential extension around the axis of the holder member, and a pair of peripheral end portions that define the intermittent portion of the mounting projection are the holder member Are arranged with their axial positions different from each other To.

この発明では、塗布部材をホルダ部材内に挿入して装着突部上に押し付けた状態で、塗布部材をホルダ部材に対して相対的に上記周方向に回転させて装着突部に対して捩じ込むことにより、塗布部材がホルダ部材に取り付けられる。
すなわち、ホルダ部材内に押し込まれた塗布部材をホルダ部材に対して相対的に上記周方向に回転させると、塗布部材は、装着突部の一対の周端部のうち上記軸線に沿う押込方向とは反対側（例えば上方）に位置する一方の周端部に上記周方向で突き当たりながら間欠部を通過することで、装着突部を上記軸線に沿う押込方向（例えば下方）に乗り越える。塗布部材を上記周方向にさらに回転させると、塗布部材が順次上記一方の周端部に突き当たり、装着突部を乗り越えていく。このように塗布部材をホルダ部材に対して回転させるにしたがって、塗布部材の係合凹部は、装着突部に到達し、装着突部が係合凹部内に嵌合する。
このように、塗布部材をホルダ部材内に押し込んだ状態で上記周方向に回転させるだけで塗布部材をホルダ部材に装着でき、例えば上述のように塗布部材をホルダ部材の下方から引き込む必要がないので、塗布部材をホルダ部材に対して容易に装着できる。
また、このように間欠部によって形成される隙間を利用して塗布部材をホルダ部材に装着させているので、装着突部の上記径方向の大きさを大きくしても、塗布部材のホルダ部材への装着容易性を維持しつつ、装着後に塗布部材をホルダ部材から抜けにくくすることができる。 In this invention, in a state where the coating member is inserted into the holder member and pressed onto the mounting projection, the coating member is rotated relative to the holder member in the circumferential direction to be twisted with respect to the mounting projection. The application member is attached to the holder member.
That is, when the coating member pushed into the holder member is rotated in the circumferential direction relative to the holder member, the coating member is pushed in the pushing direction along the axis among the pair of circumferential end portions of the mounting protrusion. Passes through the intermittent portion while striking one circumferential end located on the opposite side (for example, the upper side) in the circumferential direction, so as to get over the mounting projection in the pushing direction (for example, the lower side) along the axis. When the applicator member is further rotated in the circumferential direction, the applicator member sequentially hits the one peripheral end portion, and gets over the mounting projection. Thus, as the application member is rotated with respect to the holder member, the engaging recess of the application member reaches the mounting protrusion, and the mounting protrusion fits into the engagement recess.
Thus, the application member can be attached to the holder member simply by rotating the application member in the holder member in the circumferential direction, and for example, it is not necessary to draw the application member from below the holder member as described above. The application member can be easily attached to the holder member.
In addition, since the application member is attached to the holder member using the gap formed by the intermittent portion in this way, even if the radial size of the attachment protrusion is increased, the application member can be moved to the holder member. It is possible to make it difficult to remove the application member from the holder member after the attachment while maintaining the ease of attachment.

また、本発明の塗布具では、前記装着突部のうち前記軸線に沿って前記ホルダ部材の開口端側を向く面が、一対の前記周端部のうち前記ホルダ部材の軸方向の位置が前記ホルダ部材の開口端により近接する一方の周端部から当該周端部が画成する前記間欠部に対して前記周方向に離間するにしたがって、前記軸線に沿って前記開口端から離間する側に漸次向かうように傾斜してもよい。
この場合では、塗布部材を装着突部に押し付けた状態でホルダ部材に対して上記周方向で回転させたときに、塗布部材が装着突部の傾斜面に沿って案内され、塗布部材を押込方向に誘導しやすくなる。このため、塗布部材をホルダ部材に対してより容易に装着できる。 In the applicator of the present invention, the surface of the mounting projection that faces the opening end of the holder member along the axis is the axial position of the holder member of the pair of peripheral ends. As one of the peripheral end portions closer to the opening end of the holder member is separated from the intermittent portion defined by the peripheral end portion in the circumferential direction, the side is separated from the opening end along the axis. You may incline so that it may go gradually.
In this case, when the application member is rotated against the holder member in the circumferential direction while being pressed against the mounting protrusion, the application member is guided along the inclined surface of the mounting protrusion, and the application member is pushed in the pushing direction. It becomes easy to guide to. For this reason, an application | coating member can be more easily mounted | worn with respect to a holder member.

また、本発明の塗布具では、一対の前記周端部のうち前記ホルダ部材の軸方向の位置が前記ホルダ部材の開口端により近接する一方の周端部において前記軸線に沿って前記開口端側の反対側を向く面が、当該周端部が画成する前記間欠部に対して前記周方向に離間するにしたがって、前記軸線に沿って前記開口端から離間する側に漸次向かうように傾斜してもよい。
この場合では、塗布部材を装着突部に押し付けた状態でホルダ部材に対して上記周方向で回転させたときに、塗布部材のうち一方の周端部に突き当てられた部分が、この傾斜面によって案内されることにより、装着突部のうち塗布部材の押込方向へ潜り込みやすくなる。塗布部材のうち装着突部を乗り越えた部分は、装着突部によって塗布部材の押込方向へ案内され、塗布部材が塗布部材の押込方向に誘導される。このため、塗布部材をホルダ部材に対してより容易に装着できる。 In the applicator according to the present invention, the opening end side of the pair of peripheral end portions along the axis line at one peripheral end portion of the holder member closer to the opening end of the holder member. The surface facing the opposite side is gradually inclined toward the side away from the opening end along the axis as the distance from the intermittent portion defined by the circumferential end increases in the circumferential direction. May be.
In this case, when the coating member is pressed against the mounting projection and rotated in the circumferential direction with respect to the holder member, a portion of the coating member that is abutted against one circumferential end is the inclined surface. It becomes easy to sink in the pushing direction of an application member among mounting protrusions by being guided by. The portion of the application member that has passed the mounting protrusion is guided by the mounting protrusion in the direction in which the application member is pushed, and the application member is guided in the direction in which the application member is pushed. For this reason, an application | coating member can be more easily mounted | worn with respect to a holder member.

この発明にかかる塗布具によれば、塗布部材をホルダ部材内に挿入して装着突部に押し付けた状態で、ホルダ部材に対して相対的に上記周方向に回転させて捩じ込むことにより、例えば塗布部材をホルダ部材の下方から引き込む必要がなく、塗布部材をホルダ部材に対して容易に装着できる。 According to the applicator according to the present invention, in a state where the applicator member is inserted into the holder member and pressed against the mounting protrusion, by rotating relative to the holder member in the circumferential direction and screwing, For example, it is not necessary to draw the application member from below the holder member, and the application member can be easily attached to the holder member.

The insertion portion 53 is inserted into the through hole 13 A of the application member 13, and the upper end portion projects upward from the upper plate portion 51, and serves as a holding portion for the jig 50.

塗布部材１３を治具５０で保持した後、図４（ｂ）に示すように、治具５０を中心軸Ｏ回り（上方からの平面視で反時計回り）で回転させながら、塗布部材１３をホルダ部材１２に対して上方から押し込む。これにより、塗布部材１３の下面は、装着突部３１の上面に押し付けられる。塗布部材１３がホルダ部材１２に対して中心軸Ｏ回りで回転されているので、塗布部材１３の下端部は、装着突部３１の第１及び第２部分３３、３４における周端部３３Ａ、３４Ａに対して周方向で突き当たる。そして、図５（ａ）に示すように、塗布部材１３のうち周端部３３Ａ、３４Ａに突き当たった部分は、係合凹部１３Ｂのうちこの部分に上下方向で対応する部分が下方へ開くことによって捲れ、間欠部３２を通って装着突部３１の下方へ潜り込み、装着突部３１を下方に乗り越える。 After the application member 13 is held by the jig 50, as shown in FIG. 4B, the application member 13 is moved while rotating the jig 50 around the central axis O (counterclockwise in a plan view from above). Push into the holder member 12 from above. As a result, the lower surface of the application member 13 is pressed against the upper surface of the mounting protrusion 31. Since the applying member 13 is rotated about the central axis O with respect to the holder member 12, the lower end portion of the applying member 13 is the peripheral end portions 33 A and 34 A in the first and second portions 33 and 34 of the mounting protrusion 31. Against the circumferential direction. And as shown to Fig.5 (a), the part which collided with peripheral edge part 33A, 34A among the application members 13 opens a part corresponding to this part in an up-down direction among engagement recessed parts 13B downward. Drowning, diverging through the intermittent portion 32 and under the mounting projection 31, gets over the mounting projection 31 downward.

さらに塗布部材１３をホルダ部材１２に対して中心軸Ｏ回りに回転させると、図５（ｂ）に示すように、塗布部材１３の下端部のうち周端部３３Ａ、３４Ａに突き当たった部分が装着突部３１を順次下方に乗り越える。塗布部材１３の下端部が全周にわたって装着突部３１を下方に乗り越えると、塗布部材１３の係合凹部１３Ｂは、全周にわたって装着突部３１と嵌合する。
その後、塗布部材１３から治具５０を取り外す。以上のようにして、塗布部材１３をホルダ部材１２に装着する。
ここで、塗布部材１３をホルダ部材１２に対して中心軸Ｏ回りで１回転させることによって塗布部材１３をホルダ部材１２に装着させてもよく、２回転以上させることによって塗布部材１３をホルダ部材１２に装着させてもよい。また、塗布部材１３をホルダ部材１２に対して上方から押し込んだ時点で塗布部材１３の係合凹部１３Ｂの一部が装着突部３１と嵌合していてもよい。さらに、治具５０を用いずに塗布部材１３をホルダ部材１２に装着してもよい。 Further, when the coating member 13 is rotated around the central axis O with respect to the holder member 12, as shown in FIG. 5B, the portion of the lower end portion of the coating member 13 that hits the peripheral end portions 33A and 34A is mounted. Get over the protrusions 31 sequentially. When the lower end portion of the coating member 13 rides down the mounting protrusion 31 over the entire circumference, the engaging recess 13B of the coating member 13 is fitted with the mounting protrusion 31 over the entire circumference.
Thereafter, the jig 50 is removed from the application member 13. The application member 13 is mounted on the holder member 12 as described above.
Here, the applicator member 13 may be mounted on the holder member 12 by rotating the applicator member 13 around the central axis O with respect to the holder member 12, or the applicator member 13 may be attached to the holder member 12 by making two or more turns. It may be attached to. In addition, a part of the engagement recess 13 B of the application member 13 may be fitted to the mounting protrusion 31 when the application member 13 is pushed into the holder member 12 from above. Further, the application member 13 may be attached to the holder member 12 without using the jig 50.

以上のような構成の塗布具１によれば、塗布部材１３を装着突部３１上に押し付けるようにホルダ部材１２内に挿入した状態でホルダ部材１２に対して相対的に周方向で回転させて捩じ込むだけで、塗布部材１３をホルダ部材１２に対して容易に装着できる。
ここで、装着突部３１の上面が周方向で進むにしたがって下方に向かうように傾斜しているので、塗布部材１３の下端部を下方に誘導しやすくなり、塗布部材１３の装着をより容易にする。
また、装着性を低下させることなく装着突部３１の径方向の幅を広くすることができるので、装着後に塗布部材１３を上方へ引っ張るなどしても、塗布部材１３がホルダ部材１２から離脱しにくくなる。 According to the applicator 1 having the above configuration, the applicator member 13 is rotated in the circumferential direction relative to the holder member 12 in a state where the applicator member 13 is inserted into the holder member 12 so as to be pressed onto the mounting protrusion 31. The application member 13 can be easily attached to the holder member 12 simply by screwing.
Here, since the upper surface of the mounting protrusion 31 is inclined so as to go downward as it advances in the circumferential direction, the lower end portion of the application member 13 can be easily guided downward, and the application member 13 can be mounted more easily. To do.
Further, since the radial width of the mounting protrusion 31 can be increased without degrading the mounting performance, the coating member 13 is detached from the holder member 12 even if the coating member 13 is pulled upward after mounting. It becomes difficult.

次に、本発明の第２実施形態にかかる塗布具を、図面に基づいて説明する。なお、ここで説明する実施形態は、その基本的構成が上述した実施形態と同様であり、上述した実施形態に別の要素を付加したものである。したがって、以下の図面において上記図面と同一構成要素に同一符号を付し、この説明を省略する。 Next, an applicator according to a second embodiment of the present invention will be described with reference to the drawings. The embodiment described here has the same basic configuration as the above-described embodiment, and is obtained by adding another element to the above-described embodiment. Therefore, in the following drawings, the same components as those in the above drawings are denoted by the same reference numerals, and the description thereof is omitted.

図６及び図７に示すように、本実施形態にかかる塗布具のホルダ部材１００の装着突部１０１では、第１及び第２部分１０２、１０３の一方の周端部１０２Ａ、１０３Ａの下面が、上方からの平面視で時計回りに向かうにしたがって上方を向かうように傾斜している。
このような構成のホルダ部材１００に塗布部材１３を装着する場合には、上述した実施形態と同様に例えば治具５０を用いて塗布部材１３をホルダ部材１００内に押し込むが、塗布部材１３の下端部のうち装着突部１０１の第１及び第２部分１０２、１０３において上方からの平面視で反時計回り側にある一方の周端部に突き当たる部分は、これら周端部の下面に形成されている傾斜面に沿って下方へ案内される。そして、塗布部材１３の上記部分は、間欠部３２を通って装着突部１０１の下方へ潜り込み、装着突部１０１を下方に乗り越える。その後、上述した実施形態と同様に塗布部材１３をホルダ部材１００に装着する。 As shown in FIGS. 6 and 7, in the mounting protrusion 101 of the holder member 100 of the applicator according to the present embodiment, the lower surfaces of the peripheral end portions 102 A and 103 A of the first and second portions 102 and 103 are It inclines so that it may go upwards as it goes clockwise in planar view from upper direction.
When the application member 13 is mounted on the holder member 100 having such a configuration, the application member 13 is pushed into the holder member 100 using, for example, the jig 50 as in the above-described embodiment. The portion of the first and second portions 102 and 103 of the mounting protrusion 101 that strikes one of the peripheral ends on the counterclockwise side in plan view from above is formed on the lower surface of these peripheral ends. It is guided downward along the inclined surface. Then, the portion of the application member 13 passes through the intermittent portion 32 and sinks below the mounting protrusion 101, and gets over the mounting protrusion 101. Thereafter, the application member 13 is mounted on the holder member 100 in the same manner as in the above-described embodiment.

以上のような構成のホルダ部材１００を備える塗布具でも、上述した実施形態と同様の作用、効果を奏するが、塗布部材１３の下端部のうち上記一方の周端部に突き当たる部分がこれら周端部の下面に沿って案内され、装着突部１０１よりも下方へ潜り込みやすくなる。したがって、塗布部材１３をホルダ部材１００に対してより容易に装着できる。
なお、本実施形態では、第１及び第２部分１０２、１０３のうち上記一方の周端部の下面のみを傾斜面としているが、例えば図７に示すようなホルダ部材１１０であってもよい。このホルダ部材１１０では、装着突部１１１の第１及び第２部分１１２、１１３それぞれの下面全体が、上面と同様に、上方からの平面視で反時計回り側にある一方の周端部から他方の周端部まで上方からの平面視で時計回りに向かうにしたがって上方を向くように傾斜している。 Even in the applicator provided with the holder member 100 having the above-described configuration, the same functions and effects as those of the above-described embodiment can be obtained. It is guided along the lower surface of the part, and it is easier to sink below the mounting protrusion 101. Therefore, the application member 13 can be more easily attached to the holder member 100.
In the present embodiment, only the lower surface of the one peripheral end portion of the first and second portions 102 and 103 is an inclined surface. However, for example, a holder member 110 as shown in FIG. 7 may be used. In this holder member 110, the entire lower surface of each of the first and second portions 112 and 113 of the mounting protrusion 111 is the same as the upper surface from one peripheral end portion on the counterclockwise side in plan view from the top to the other. It is inclined so as to face upward as it goes clockwise in a plan view from above up to the peripheral end portion.

なお、本発明は上記実施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できる。
例えば、ホルダ部材の装着突部の形状は、例えば図８から図１３に示すような形状など、適宜変更されてもよい。
図８及び図９に示すホルダ部材１２０では、装着突部１２１に間欠部１２２が１つのみ形成されている。
また、図１０及び図１１に示すホルダ部材１３０では、装着突部１３１に４つの間欠部１３２が形成されており、装着突部１３１は、第１から第４部分１３３〜１３６に分割されている。間欠部１３２は、装着突部１３１において周方向で等間隔に形成されている。
さらに、図１２に示すホルダ部材１４０の上端部の内周面には、雌ネジ部１４１が形成されている。これに対応して、塗布部材（図示略）にも雄ネジ部が形成されている。このようなホルダ部材１４０では、塗布部材を中心軸回りに回転させて塗布部材をホルダ部材１４０に螺合させていくだけで塗布部材を装着突部３１に対して押し付けることができる。なお、塗布部材が弾性変形することによって雌ネジ部１４１と係合することができるので、塗布部材には雄ネジ部を形成しなくてもよい。
また、図１３に示すホルダ部材１５０では、装着突部１５１を形成する第１及び第２部分１５２、１５３の一対の周端部のうち上下方向の厚さが薄い一方の周端部（上方から見た平面視で反時計回り方向側の周端部）の下面には、下方に向けて係止突部１５１Ａが突設されている。なお、図１３には、第１部分１５２に形成された係止突部１５１Ａのみ示されているが、第２部分１５３にも同様に係止突部１５１Ａが形成されている。この係止突部１５１Ａは、塗布部材１３の係合凹部１３Ｂに装着突部１５１に嵌合させると、塗布部材１３に引っかかることにより、塗布部材１３をホルダ部材１５０からより離脱しにくくさせる。
ここで、このような構成の装着突部１２１、１３１の下面の形状を上述した第２実施形態にかかる装着突部１０１、１１１と同様の形状としてもよい。また、ホルダ部材１４０の装着突部３１の形状を第２実施形態にかかる装着突部１０１、１１１や上述した装着突部１２１、１３１の形状としてもよい。同様に、ホルダ部材１５０の装着突部１５１の形状を第２実施形態にかかる装着突部１０１、１１１や上述した装着突部１２１、１３１と同様の形状としてもよい。図１２に示すホルダ部材１４０の雌ネジ部１４１を図７に示すホルダ部材１１０に適用する際には、雌ネジ部１４１によって画成される径方向内側に向けて突出する突出部分と装着突部１１１とが一体となって螺旋形状を形成するように配設されていることも可能である。 In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the shape of the mounting protrusion of the holder member may be changed as appropriate, for example, as shown in FIGS.
In the holder member 120 shown in FIGS. 8 and 9, only one intermittent portion 122 is formed on the mounting protrusion 121.
Further, in the holder member 130 shown in FIGS. 10 and 11, four intermittent portions 132 are formed in the mounting protrusion 131, and the mounting protrusion 131 is divided into first to fourth portions 133 to 136. . The intermittent portions 132 are formed at equal intervals in the circumferential direction in the mounting protrusion 131.
Furthermore, a female screw portion 141 is formed on the inner peripheral surface of the upper end portion of the holder member 140 shown in FIG. Correspondingly, a male screw portion is also formed on the application member (not shown). In such a holder member 140, the application member can be pressed against the mounting protrusion 31 simply by rotating the application member around the central axis and screwing the application member into the holder member 140. In addition, since it can engage with the internal thread part 141 by elastically deforming an application member, it is not necessary to form an external thread part in an application member.
Further, in the holder member 150 shown in FIG. 13, one of the pair of peripheral ends of the first and second portions 152 and 153 forming the mounting protrusion 151 has one peripheral end portion (from above) that is thin in the vertical direction. On the lower surface of the counterclockwise direction side peripheral end in a plan view as seen, a locking projection 151A is projected downward. In FIG. 13, only the locking protrusion 151 A formed on the first portion 152 is shown, but the locking protrusion 151 A is similarly formed on the second portion 153. When the engaging protrusion 151 A is fitted to the mounting protrusion 151 in the engaging recess 13 B of the application member 13, the engagement protrusion 151 A is caught by the application member 13, thereby making the application member 13 less likely to be detached from the holder member 150.
Here, the shape of the lower surface of the mounting protrusions 121 and 131 having such a configuration may be the same as that of the mounting protrusions 101 and 111 according to the second embodiment described above. The shape of the mounting protrusion 31 of the holder member 140 may be the shape of the mounting protrusions 101 and 111 according to the second embodiment and the mounting protrusions 121 and 131 described above. Similarly, the shape of the mounting protrusion 151 of the holder member 150 may be the same as the mounting protrusions 101 and 111 according to the second embodiment and the mounting protrusions 121 and 131 described above. When the female screw portion 141 of the holder member 140 shown in FIG. 12 is applied to the holder member 110 shown in FIG. 7, a protruding portion and a mounting protrusion that protrude inward in the radial direction defined by the female screw portion 141. It is also possible to arrange them so as to form a spiral shape together with 111.

装着突部は、上面が一方の周端部から他方の周端部に周方向に向かうにしたがって下方に向かうように傾斜しているが、間欠部を画成する一対の周端部が上下方向で位置を互い異ならせて配置されていれば、上面を傾斜させる必要はない。
装着突部は、上下方向で１つのみ形成されているが、複数形成されてもよい。同様に、塗布部材には、係合凹部が上下方向で複数形成されてもよい。
間欠部は、少なくとも１つ形成されていればよく、３つや５つ以上形成されてもよい。
装着部材とホルダ部材とは、別体として形成されているが、一体に形成されてもよい。
ホルダ部材の中心軸線は、容器本体の中心軸線と一致している必要はなく、容器本体の中心軸線と平行であっても、角度をなしていてもよい。
ホルダ部材の形状は、筒状であれば、円筒状に限らず、角筒状など、他の形状であってもよい。同様に、塗布部材の形状は、円柱状に限らず、角柱状など、他の形状であってもよい。
塗布部材は、容器本体内から流出させた内容物を被塗布部に塗布できれば、スポンジに限らず、他の部材で形成されてもよい。
装着部材には、塗布部材の貫通孔内に挿入される延長筒部が設けられているが、延長筒部が設けられていなくてもよく、塗布部材に貫通孔が形成されていなくてもよい。また、装着部材に延長筒部を設けない替わりに、カバー部材の栓柱部が連通孔を閉塞する構成としてもよい。 The mounting projection is inclined such that the upper surface is directed downward from one peripheral end portion toward the other peripheral end portion in the circumferential direction, but the pair of peripheral end portions defining the intermittent portion is in the vertical direction. If the positions are different from each other, it is not necessary to incline the upper surface.
Although only one mounting protrusion is formed in the vertical direction, a plurality of mounting protrusions may be formed. Similarly, a plurality of engaging recesses may be formed in the application member in the vertical direction.
It is sufficient that at least one intermittent portion is formed, and three or five or more intermittent portions may be formed.
The mounting member and the holder member are formed as separate bodies, but may be formed integrally.
The center axis of the holder member does not need to coincide with the center axis of the container body, and may be parallel to or angled with the center axis of the container body.
The shape of the holder member is not limited to a cylindrical shape as long as it is cylindrical, and may be other shapes such as a rectangular tube. Similarly, the shape of the application member is not limited to a cylindrical shape, but may be other shapes such as a prismatic shape.
The application member is not limited to the sponge and may be formed of other members as long as the contents discharged from the container body can be applied to the application portion.
The mounting member is provided with an extended cylinder portion that is inserted into the through hole of the application member. However, the extension cylinder portion may not be provided, and the through hole may not be formed in the application member. . Moreover, it is good also as a structure which the plug column part of a cover member obstruct | occludes a communicating hole instead of providing an extended cylinder part in a mounting member.
