JP 2000-262324 A

ここで、上記装置にあっては、1回のクリック感での液状充填物の吐出量(出現量)をさらに少なくし液状充填物を出し過ぎないようにしたいという要望がある。このような要望を実現するには、ラチェット歯の個数を多くし、本体筒と操作筒の相対回転による1回転当たりのクリック回数を多くすれば良いが、このようにラチェット歯の個数を多くすると、ラチェット歯を成型するための金型の加工時間が長くなると共に、成型時の冷却時間が長くなって成型時間が長くなり、従って、製造コストが高くなる。   Here, in the above apparatus, there is a demand for further reducing the discharge amount (appearance amount) of the liquid filler with one click feeling so that the liquid filler is not excessively discharged. In order to realize such a demand, the number of ratchet teeth can be increased and the number of clicks per rotation due to the relative rotation of the main body cylinder and the operation cylinder can be increased, but if the number of ratchet teeth is increased in this way, The processing time of the mold for forming the ratchet teeth becomes longer, the cooling time at the time of molding becomes longer, the molding time becomes longer, and the manufacturing cost becomes higher.

特に、1回のクリック感での液状充填物の吐出量を例えば従来の半分以下としたい場合には、ラチェット歯の個数を従来の2倍以上とする(従来8個なら16個以上とする)必要がある。   In particular, when it is desired to reduce the discharge amount of the liquid filling in one click feeling, for example, to less than half of the conventional amount, the number of ratchet teeth is more than twice that of the conventional one (16 in the case of eight conventional). There is a need.

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、ラチェット歯の個数を必要以上に増やさず製造コストを高めること無く、1回のクリック感での塗布材の出現量を少なくし出し過ぎを防止できる塗布材押出容器を提供することを目的とする。   The present invention has been made in order to solve such a problem, and without increasing the number of ratchet teeth more than necessary and without increasing the manufacturing cost, the amount of the coating material appearing with a single click feeling can be reduced. It is an object of the present invention to provide a coating material extruding container that can prevent excessive discharge.

本発明による塗布材押出容器は、容器前部と容器後部との相対回転により、容器内の螺合部が働き容器内の移動体が前進することで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において、容器前部及び容器後部は、各々、軸線周り回転方向に係合し相対回転に従う移動体の移動に伴いクリック感を付与するクリック歯を備え、一方のクリック歯は、円周等分割の複数箇所に設けられ、他方のクリック歯は、円周非等分の複数箇所に設けられ、相対回転による一回転当たりのクリック回数が、円周等分割の複数箇所より多いクリック回数となることを特徴としている。   In the coating material extrusion container according to the present invention, the relative rotation between the container front part and the container rear part causes the screwing part in the container to work, and the moving body in the container moves forward, so that the coating material in the container moves from the opening at the tip of the container. In the appearing coating material extruding container, the container front part and the container rear part are each provided with a click tooth that engages in the rotational direction around the axis and gives a click feeling with the movement of the moving body according to the relative rotation. The other click teeth are provided at a plurality of non-equal parts of the circumference, and the number of clicks per rotation by relative rotation is greater than that of the plurality of parts at the same circumference division. It is characterized by clicks.

このような塗布材押出容器によれば、一方のクリック歯が例えば従来のように円周等分割の複数箇所に設けられているのに対して、他方のクリック歯が円周非等分の複数箇所に設けられているため、ラチェット歯の個数を必要以上に増やすこと無く、容器前部と容器後部の相対回転による一回転当たりのクリック回数を、円周等分割の複数箇所より多いクリック回数とすることができ、1回のクリック感での塗布材の出現量を少なくできる。このため、製造コストを高めること無く、1回のクリック感での塗布材の出し過ぎを防止できる。   According to such a coating material extruding container, one click tooth is provided at a plurality of equally divided circumferential positions as in the prior art, while the other click tooth has a plurality of circumferentially unequal parts. Since the number of ratchet teeth is not increased more than necessary, the number of clicks per rotation due to the relative rotation of the container front part and the container rear part is more than the number of clicks more than a plurality of circumferentially divided parts. It is possible to reduce the appearance amount of the coating material with a single click feeling. For this reason, it is possible to prevent excessive application of the coating material with a single click feeling without increasing the manufacturing cost.

ここで、一方のクリック歯は、円周等分割の8箇所に設けられ、他方のクリック歯は、円周非等分の8箇所に設けられ、相対回転による一回転当たりのクリック回数が、16回以上となるようにすると、クリック歯の個数に対してクリック回数が2倍以上となり、少ないクリック歯の個数で、1回のクリック感での塗布材の出現量を大幅に少なくできる。   Here, one of the click teeth is provided at eight places on the circumference equally divided, the other click tooth is provided at eight places on the circumference unequal, and the number of clicks per one rotation by relative rotation is 16 When the number of clicks is increased, the number of clicks becomes twice or more than the number of click teeth, and the appearance amount of the coating material with a single click feeling can be greatly reduced with a small number of click teeth.

また、上記作用を効果的に奏する具体的な構成としては、他方のクリック歯は、円周90°ごとの4箇所と、この4箇所のうちの対向する2箇所から時計回り、反時計回りに各々22.5°回転した4箇所に設けられている構成が挙げられる。これによれば、上記相対回転時に、各クリック歯に負荷がバランス良く作用することになる。   In addition, as a specific configuration that effectively exhibits the above-described operation, the other click tooth has four positions every 90 ° in the circumference, and two counterclockwise positions out of the four positions clockwise and counterclockwise. The structure provided in four places each rotated 22.5 degrees is mentioned. According to this, at the time of the relative rotation, the load acts on each click tooth with a good balance.

また、容器前部のクリック歯又は容器後部のクリック歯の何れか一方は、当該クリック歯を軸線方向に付勢する弾性体を一体で備えていると、部品点数が低減されると共に、成型、組立等の製造が簡易とされ、製造コストの低減が図られる。   Moreover, when either one of the click teeth at the front of the container or the click teeth at the rear of the container is integrally provided with an elastic body that urges the click teeth in the axial direction, the number of parts is reduced, and molding, Manufacturing such as assembly is simplified, and the manufacturing cost is reduced.

また、クリック歯は、移動体を繰り戻す方向の相対回転を規制し、移動体を繰り出す方向の相対回転のみを許容するラチェット歯であっても良い。   Further, the click tooth may be a ratchet tooth that restricts relative rotation in the direction in which the moving body is fed back and allows only relative rotation in the direction in which the moving body is fed out.

このように本発明による塗布材押出容器によれば、ラチェット歯の個数を必要以上に増やさないため製造コストを高めること無く、1回のクリック感での塗布材の出現量を少なくでき出し過ぎを防止することが可能となる。   Thus, according to the coating material extruding container according to the present invention, the number of the ratchet teeth is not increased more than necessary, and thus the appearance amount of the coating material can be reduced with a single click feeling without increasing the manufacturing cost. It becomes possible to prevent.

以下、本発明による塗布材押出容器の好適な実施形態について図1〜図10を参照しながら説明する。なお、各図において、同一の要素には同一符号を付し、重複する説明は省略する。図1及び図2は、本発明の実施形態に係る塗布材押出容器の各状態を示す縦断面図、図3〜図6は、クリック雌螺子部材を示す各図、図7〜図10は、クリックバネ部材を示す各図であり、本実施形態の塗布材押出容器は、塗布材を収容すると共に適宜使用者の操作により押し出し可能とするものである。   Hereinafter, a preferred embodiment of a coating material extruding container according to the present invention will be described with reference to FIGS.

A rotation preventing mechanism 60 is constituted by the recessed groove 4b, and a ratchet mechanism 20 is constituted by the ratchet teeth 5r of the click female screw member 5, the ratchet teeth 6r of the click spring member 6, and the compression spring 6a of the click spring member 6.

次に、クリック雌螺子部材5のラチェット歯5r、クリックバネ部材6のラチェット歯6rについて説明する。   Next, the ratchet teeth 5r of the click female screw member 5 and the ratchet teeth 6r of the click spring member 6 will be described.

クリック雌螺子部材5のラチェット歯5rは、図6に示すように、円周等分割の複数箇所に設けられ、ここでは、円周等分割の8箇所、すなわち、円周方向45°ごとに設けられている。   As shown in FIG. 6, the ratchet teeth 5 r of the click female screw member 5 are provided at a plurality of circumferentially equal divisions, and here, provided at eight circumferentially equal divisions, that is, every 45 ° in the circumferential direction. It has been.

ここで、特に本実施形態のクリックバネ部材6のラチェット歯6rは、図10に示すように、円周非等分の複数箇所に設けられ、ここでは、円周非等分の8箇所に設けられている。より具体的には、ラチェット歯6rは、円周方向90°ごとの4箇所と、この4箇所のうちの対向する2箇所から時計回り、反時計回りに各々22.5°回転した4箇所に設けられている。   Here, in particular, the ratchet teeth 6r of the click spring member 6 according to the present embodiment are provided at a plurality of locations with unequal circumferences, as shown in FIG. It has been. More specifically, the ratchet teeth 6r are provided at four locations every 90 ° in the circumferential direction, and at four locations rotated by 22.5 ° clockwise and counterclockwise from the two opposing locations of the four locations. Is provided.

このように構成された塗布材押出容器100にあっては、使用者により図1に示すキャップ8が本体筒1から取り外され、本体筒1と操作筒2とが一方向に相対回転されると、ラチェット歯5r,6rも同期して一方向に相対回転し、使用者にはラチェット歯5r,6r同士が係合する度にクリック感(抵抗感)が与えられながら、移動体4が、図2に示すように、相対回転に従い先端側に順次繰り出され、この繰り出される移動体4の先端のピストン3により、充填領域1xの塗布材Lは、先端側に順次押し出され、本体筒1の先端部に装着されたパイプ部材9を通り、当該パイプ部材9の先端の開口9aから出現しブラシ7に吐出されて使用状態とされる。   In the coating material extruding container 100 configured as described above, when the user removes the cap 8 shown in FIG. 1 from the main body cylinder 1 and the main body cylinder 1 and the operation cylinder 2 are relatively rotated in one direction. The ratchet teeth 5r and 6r are also relatively rotated in one direction synchronously, and the user is given a click feeling (resistance feeling) each time the ratchet teeth 5r and 6r are engaged with each other. 2, the coating material L in the filling region 1x is sequentially pushed out to the tip side by the piston 3 at the tip of the moving body 4 that is fed out in accordance with relative rotation. It passes through the pipe member 9 attached to the part, emerges from the opening 9a at the tip of the pipe member 9, and is discharged to the brush 7 to be used.

この移動体4の繰り出し時にあっては、クリック雌螺子部材5のラチェット歯5rが円周等分割の複数箇所に設けられているのに対して、クリックバネ部材6のラチェット歯6rが円周非等分の複数箇所に設けられているため、ラチェット歯の個数を必要以上に増やすこと無く、本体筒1と操作筒2の相対回転による一回転当たりのクリック回数が、円周等分割の複数箇所より多いクリック回数とされ、1回のクリック感での塗布材Lの出現量が少なくされている。従って、製造コストを高めること無く、1回のクリック感での塗布材Lの出し過ぎが防止されている。   When the moving body 4 is extended, the ratchet teeth 5r of the click female screw member 5 are provided at a plurality of equally divided portions, whereas the ratchet teeth 6r of the click spring member 6 are not circumferential. Since it is provided at multiple equal parts, the number of clicks per rotation due to the relative rotation of the main body cylinder 1 and the operation cylinder 2 can be increased at an equal number of circumferences without increasing the number of ratchet teeth more than necessary. The number of clicks is increased, and the appearance amount of the coating material L with one click feeling is reduced. Therefore, it is possible to prevent the coating material L from being taken out with one click feeling without increasing the manufacturing cost.

具体的には、クリック雌螺子部材5のラチェット歯5rが円周等分割の8箇所に設けられ、クリックバネ部材6のラチェット歯6rが円周非等分の8箇所に設けられ、相対回転による一回転当たりのクリック回数が16回とされているため、ラチェット歯5rの個数に対してクリック回数が2倍となり、少ないラチェット歯5r,6rの個数で、1回のクリック感での塗布材Lの出現量が大幅に少なくされている。   Specifically, the ratchet teeth 5r of the click female screw member 5 are provided at eight equal circumferential divisions, and the ratchet teeth 6r of the click spring member 6 are provided at eight non-equal circumferences, which are caused by relative rotation. Since the number of clicks per rotation is 16, the number of clicks is twice the number of ratchet teeth 5r, and the coating material L can be applied with a single click feeling with a small number of ratchet teeth 5r, 6r. The amount of appearance has been greatly reduced.

そして、クリックバネ部材6のラチェット歯6rは、円周90°ごとの4箇所と、この4箇所のうちの対向する2箇所から時計回り、反時計回りに各々22.5°回転した4箇所に設けられているため、上記相対回転時に、各ラチェット歯5r,6rに負荷がバランス良く作用することになる。   Then, the ratchet teeth 6r of the click spring member 6 are provided at four locations each having a circumference of 90 ° and four locations rotated by 22.5 ° clockwise and counterclockwise from the two opposing locations. Therefore, the load acts on the ratchet teeth 5r and 6r in a balanced manner during the relative rotation.

また、本実施形態にあっては、クリックバネ部材6のラチェット歯6rが、当該ラチェット歯6rを軸線方向に付勢する圧縮バネ6aを一体で備えているため、部品点数が低減されると共に、成型、組立等の製造が簡易とされ、製造コストの低減が図られている。因みに、クリック雌螺子部材5のクリック歯5rが圧縮バネ6aを一体で備えるようにし、同様な作用・効果を奏するようにしても良い。   Further, in this embodiment, the ratchet teeth 6r of the click spring member 6 are integrally provided with a compression spring 6a that urges the ratchet teeth 6r in the axial direction, so that the number of parts is reduced, Manufacturing such as molding and assembly is simplified, and the manufacturing cost is reduced. Incidentally, the click teeth 5r of the click female screw member 5 may be integrally provided with the compression spring 6a so as to achieve the same operation and effect.

なお、本実施形態においては、特に好ましい作用・効果を奏するとして、ラチェット歯6rを図10に示す非等分配置としているが、これに限定されるものではない。また、ラチェット歯5r,6r同士を逆にし、クリック雌螺子部材5のラチェット歯5rを非等分配置とし、クリックバネ部材6のラチェット歯6rを等分配置としても良い。   In the present embodiment, the ratchet teeth 6r are arranged in an unequal arrangement as shown in FIG. 10 to provide particularly preferable actions and effects, but the present invention is not limited to this. Further, the ratchet teeth 5r, 6r may be reversed, the ratchet teeth 5r of the click female screw member 5 may be non-equally arranged, and the ratchet teeth 6r of the click spring member 6 may be equally divided.

そして、等分配置のラチェット歯のピッチ、非等分配置のラチェット歯のピッチ、個数、配置等を適宜変更することにより、上記相対回転による一回転当たりのクリック回数を、円周等分割の複数箇所の2倍より多いクリック回数(本実施形態に例えると2倍の16回より多い回数)とすることができる。   Then, by appropriately changing the pitch, the number, the arrangement, and the like of the ratchet teeth that are equally divided and the ratchet teeth that are not evenly arranged, the number of clicks per one rotation by the relative rotation can be changed to a plurality of equal circumferential divisions. The number of clicks can be more than twice as many as the number of places (in this embodiment, twice as many as 16 times).

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4を繰り戻す他方向への本体筒1と操作筒2の相対回転を規制し、移動体4を繰り出す一方向への本体筒1と操作筒2の相対回転のみを許容するラチェット歯5r,6rを有するラチェット機構20としているが、ラチェット歯5r,6rの形状を周方向に沿って例えば登り傾斜と下り傾斜を有する山型のクリック歯とし、移動体4を繰り出す一方向への相対回転に加えて移動体4を繰り戻す他方向への相対回転を許容するクリック機構とすることも可能である。この場合も、他方向への相対回転時に、クリック歯同士が回転方向の係合及びその解除を繰り返し、クリック感が生じることになる。   As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the main body in the other direction in which the moving body 4 is fed back. Although the ratchet mechanism 20 has ratchet teeth 5r and 6r that restrict the relative rotation of the cylinder 1 and the operation cylinder 2 and allow only the relative rotation of the main body cylinder 1 and the operation cylinder 2 in one direction for feeding out the moving body 4. The ratchet teeth 5r, 6r are shaped like mountain-shaped click teeth having, for example, an upward slope and a downward slope along the circumferential direction, and the other direction in which the movable body 4 is fed back in addition to the relative rotation in one direction in which the movable body 4 is fed out. It is also possible to use a click mechanism that allows relative rotation to the. Also in this case, at the time of relative rotation in the other direction, the click teeth repeatedly engage and release in the rotation direction, and a click feeling is generated.

また、上記実施形態においては、塗布材Lを、例えば、液状や、ゼリー状、ゲル状、ペースト状を含む練り状等の半固体や軟固形状等とした場合に、特に好適な塗布材押出容器100について述べているが、塗布材を、例えば、アイライナー、アイブロー、リップライナー、リップスティック等を始めとした種々の棒状化粧料、筆記用具等の棒状の芯等の棒状体とした場合に対しても適用可能である。この場合には、先端のブラシ7等の塗布体は無くされ、本体筒の先端に設けられる開口から棒状体が出没することになる。   In the above embodiment, the coating material L is particularly suitable when the coating material L is a semi-solid or soft solid such as a liquid, a jelly, a gel, or a paste including a paste. Although the container 100 is described, when the coating material is a rod-shaped body such as a rod-shaped core such as an eyeliner, an eyebrow, a lip liner, a lipstick, etc. It can also be applied to. In this case, the application body such as the brush 7 at the front end is eliminated, and the rod-shaped body appears and disappears from the opening provided at the front end of the main body cylinder.

また、雄螺子、雌螺子は、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のように螺子山と同様な働きをするものであっても良く、また、螺合突起は、連続する螺子山であっても良い。   In addition, the male screw and the female screw may function in the same manner as a screw thread, such as an intermittently arranged projection group or a spiral and intermittently arranged projection group. The mating protrusion may be a continuous screw thread.

さらに、クリック歯は、鈍角三角形、鋭角三角形、直角三角形、二等辺三角形、半球形状等、クリック感やラチェット機能に応じて種々の形状を選択することが可能である。   Further, the click tooth can be selected from various shapes such as an obtuse triangle, an acute triangle, a right triangle, an isosceles triangle, and a hemispherical shape according to the click feeling and the ratchet function.
