Description

本発明は、洗剤や化粧品、あるいは洗浄・除菌剤等の内容物を充填した容器本体を、ねじ込み式のキャップにて密閉するキャップ付き容器に関し、特に、キャップのねじ込み終了姿勢を維持する弛み止め機能につき、キャップの着脱を繰り返し行っても、その機能を長期にわたり十分に保つことができる技術を提案するものである。   The present invention relates to a container with a cap for sealing a container body filled with contents such as a detergent, cosmetics, or a cleaning / disinfecting agent with a screw-in type cap, and in particular, an anti-loosening that maintains the screwing end posture of the cap. The present invention proposes a technique that can sufficiently maintain the function over a long period of time even if the cap is repeatedly attached and detached.

容器の口部にキャップをねじ込み装着して、容器内の充填空間を密閉するキャップ付きの容器は、キャップのねじ込み終了姿勢を維持すべく、例えば容器本体に凸部を形成する一方、キャップにこの凸部に対応する凹部を設けて、キャップのねじ込み終了時に凸部が凹部に嵌まり込むことでキャップの弛みを防止することが行われている。   A cap-attached container that seals the filling space in the container by screwing the cap into the mouth of the container, for example, forms a convex part on the container body to maintain the cap screwing end posture. A concave portion corresponding to the convex portion is provided, and the cap is prevented from loosening by fitting the convex portion into the concave portion at the end of screwing of the cap.

ところで、従来のこの種の容器は、キャップを含むすべての部材が合成樹脂で構成されているのが普通であり、キャップの取り付け、取り外しを繰り返すと、凸部と凹部との擦れによって両者が次第に削れていくのが避けられないため、凸部と凹部の相互間に隙間が生じてキャップが僅かに弛んでしまうことがあり、また、凸部と凹部との引っかかりも浅くなって、小さな外力が加わった場合でも、簡単にキャップが回動してしまうおそれもあった。これらの点を解決しようとする従来技術としては、例えば特許文献1に示すような、キャップを、外キャップと、内キャップと、リング部材との3つの部材で構成し、キャップのねじ込み終了時に凸部を設けたリング部材を撓ませて、凹部との擦れを低減させようとするものが知られているが、特許文献1に示す構造では、構成部材の増加と構造の複雑化が避けられず、未だ改善の余地が残されていた。   By the way, in this type of conventional container, it is normal that all members including the cap are made of a synthetic resin. Since it is inevitable to scrape, a gap may be formed between the convex part and the concave part and the cap may be slightly loosened. Also, the catch between the convex part and the concave part becomes shallow, and a small external force is generated. Even when it is added, the cap may easily rotate. As a conventional technique for solving these points, for example, as shown in Patent Document 1, a cap is composed of three members, an outer cap, an inner cap, and a ring member, and is projected at the end of screwing of the cap. It is known that the ring member provided with the portion is bent to reduce the friction with the concave portion. However, in the structure shown in Patent Document 1, an increase in the number of constituent members and a complicated structure cannot be avoided. There was still room for improvement.

It is desirable that the loosening prevention protrusion is provided in a thin portion where the inner cap is partially thinned .

前記外キャップに、前記ストッパーの背面部に向けて突設する補強リブを設けることが望ましい。   It is desirable to provide the outer cap with a reinforcing rib projecting toward the back surface of the stopper.

前記外キャップに、前記弛み止め突起の背面部に向けて突設して、該内キャップの撓み変形量を抑制する変形抑制リブを設けることが望ましい。   It is desirable that the outer cap is provided with a deformation suppressing rib that protrudes toward the back surface of the slack prevention protrusion and suppresses the amount of bending deformation of the inner cap.

容器本体の口部にねじ込み保持されるキャップを、内筒と外筒との同心二重配置で構成し、容器本体の口部の根元台座部に、口部の径方向外側に突設する大凸部と、大凸部から周方向に間隔をおいて配設されて大凸部より低い突設量となる小凸部とを設け、キャップの内筒の内側壁部に、大凸部と突き当たってキャップのねじ込みを終了させるストッパーと、ねじ込み終了直前に小凸部を乗り越えて内筒を撓み変形させるとともに、ねじ込み終了時に小凸部と係合してその相互間の接触圧を残留させる弛み止め突起を設けたので、内筒の撓み変形によって小凸部と弛み止め突起との削れが抑制され、繰り返しキャップを着脱させても、弛み止め機能を長期にわたり十分に維持することができる。また、ねじ込み終了時には、小凸部と弛み止め突起との接触圧が残っているので、キャップの弛みがより効果的に抑制される。さらに、弛み止め機能を設けてもなお、構成部材の増加につながることがない。   A cap that is screwed and held in the mouth of the container body is configured by a concentric double arrangement of the inner cylinder and the outer cylinder. Providing a convex portion and a small convex portion disposed at a distance from the large convex portion in the circumferential direction and having a projecting amount lower than the large convex portion, and on the inner wall portion of the inner cylinder of the cap, A stopper that stops the screwing of the cap by abutting, and a slack that gets over the small convex part and deflects the inner cylinder just before the screwing is finished, and engages with the small convex part at the end of screwing to leave the contact pressure between them Since the stop projection is provided, the inner cylinder is bent and deformed to prevent the small convex portion and the slack stop projection from being scraped. Even if the cap is repeatedly attached and detached, the slack stop function can be sufficiently maintained for a long time. Further, at the end of screwing, the contact pressure between the small convex portion and the loosening prevention projection remains, so that loosening of the cap is more effectively suppressed. Furthermore, even if a loosening prevention function is provided, the number of components does not increase.

弛み止め突起を、キャップの内筒の肉厚を部分的に薄肉にした薄肉部に設ける場合は、弛み止め突起を設けた部位をより撓み易くすることが可能となり、小凸部と弛み止め突起との削れをより効果的に抑制することができるので、弛み止め機能が維持されるキャップの着脱回数を更に増加させることができる。   When the slack prevention protrusion is provided in the thin wall part where the wall thickness of the inner cylinder of the cap is partially thinned, it becomes possible to make the portion provided with the slack prevention protrusion easier to bend, and the small convex part and the slack prevention protrusion Therefore, the number of times of attaching and detaching the cap that maintains the loosening prevention function can be further increased.

ストッパーの背面部にて、キャップの内筒と外筒とを相互につなぐ補強リブを設ける場合は、ねじ込み終了時に強い回動力がキャップに加わる際にも、ストッパーに十分な耐久性を与えることができる。   When a reinforcing rib is provided on the back of the stopper to connect the inner and outer cylinders of the cap to each other, even when strong rotational force is applied to the cap at the end of screwing, sufficient durability can be given to the stopper. it can.

弛み止め突起の背面部にて、キャップの外筒と内筒とを相互につないで内筒の撓み変形量を抑制する変形抑制リブを設ける場合は、弛み止め突起に対する変形抑制リブの位置や高さを変更することで、より厳密に所期する撓み変形量を得ることができるので、小凸部と弛み止め突起との削れを抑制しつつ、不用意なキャップの開栓を防止することができる。   When providing a deformation suppression rib that suppresses the amount of bending deformation of the inner cylinder by connecting the outer cylinder and the inner cylinder of the cap to each other on the back surface of the locking protrusion, the position and height of the deformation suppression rib relative to the locking protrusion By changing the length, it is possible to obtain a more precisely expected amount of bending deformation, so that it is possible to prevent inadvertent opening of the cap while suppressing the shaving of the small convex portion and the loosening prevention projection. it can.

内筒と外筒とを同心二重配置にしたキャップ代えて、内キャップと外キャップとで構成されるキャップを用いる場合は、それぞれの機能に適した樹脂材料を選択することが可能となるので、例えば容器本体よりも硬度の高い樹脂材料を内キャップに使用して小凸部との削れに対する耐久性を向上させるとともに、外キャップは装飾性に優れる材料を採用することができる。   When a cap composed of an inner cap and an outer cap is used instead of a cap in which the inner cylinder and the outer cylinder are arranged concentrically, a resin material suitable for each function can be selected. For example, a resin material having higher hardness than the container body can be used for the inner cap to improve the durability against scraping with the small convex portion, and the outer cap can be made of a material having excellent decorativeness.

図1(a)、図2(a)において、1は容器本体であり、2は注出栓であり、3はキャップである。容器本体1、注出栓2、キャップ3は何れも合成樹脂からなるものであるが、容器本体1はガラスとすることもできる。図示の例で容器本体1は、底部付きの胴部1aに、肩部1bを介して円筒状の口部1cを連結しており、その内側を内容物が充填される充填空間Mとしている。容器本体1は、例えばシャンプー等を充填するボトルタイプの容器に限られず、ハンドクリーム等を充填するチューブタイプの容器であってもよい。   1 (a) and 2 (a), 1 is a container body, 2 is a spout, and 3 is a cap. Although the container main body 1, the pouring tap 2, and the cap 3 are all made of a synthetic resin, the container main body 1 can be made of glass. In the illustrated example, the container body 1 has a cylindrical mouth portion 1c connected to a body portion 1a with a bottom portion via a shoulder portion 1b, and a filling space M in which contents are filled. The container body 1 is not limited to a bottle type container filled with, for example, shampoo or the like, and may be a tube type container filled with hand cream or the like.

口部1cの側部外周壁1cには、螺旋状に形成された係合部nが形成されており、口部1cの根元台座部1cには、図1(b)、図2(b)に示すように、口部1cの径方向外側に突設する大凸部1cと、大凸部1cから周方向に間隔をおいて配設されるとともに大凸部1cより低い突設量となる小凸部1cとを設けている。図示の例では、2つの大凸部1cを互いに対向する位置に配置し、これらの大凸部1cから容器本体1の軸線を中心に90度ずらした位置に、2つの小凸部1cを配設しているが、大凸部1c、及び小凸部1cは、それぞれ少なくとも1つ設けられていればよい。また大凸部1cの輪郭面は、口部1cから径方向外側に向かうストレート面と、このストレート面の端縁から口部1cに向かう略円弧状の曲面とから形成されていて、2つの大凸部1cは、容器本体1の軸線を中心として点対称の関係で配置されている。 The side outer peripheral wall 1c 1 of the mouth portion 1c is formed with an engaging portion n formed in a spiral shape, and the base pedestal portion 1c 2 of the mouth portion 1c is provided with FIGS. As shown in b), a large convex portion 1c 3 protruding outward in the radial direction of the mouth portion 1c, and disposed at a distance from the large convex portion 1c 3 in the circumferential direction and lower than the large convex portion 1c 3. A small convex portion 1c 4 serving as a protruding amount is provided. In the illustrated example, the two large convex portions 1c 3 are arranged at positions facing each other, and the two small convex portions 1c are located at positions shifted from these large convex portions 1c 3 by 90 degrees about the axis of the container body 1. 4 has been arranged, Daitotsu portion 1c 3, and small protrusions 1c 4 only needs to be provided at least one, respectively. The contoured surface of Daitotsu portion 1c 3 includes a straight surface toward the radially outer side from the mouth portion 1c, this and from the edge of the straight surface is formed from a substantially arc-shaped curved surfaces toward the mouth portion 1c, two The large convex portions 1c 3 are arranged in a point-symmetric relationship with the axis of the container body 1 as the center.

また、図1(a)、図2(a)に示す例では、口部1cの先端開口1cの外壁面に爪部1cが形成されており、注出栓2に天面壁2aより同心二重配置で垂下される内壁2b、及び外壁2cが設けられていて、内壁2b、及び外壁2cの相互間に形成される環状凹部に爪部1cを挿入させるとともに外壁2cの先端に設けられた爪部2dを爪部1cに係合させて、注出栓2を口部1cに位置決め固定している。また、天面壁2aの中央部には注出孔2eが設けられていて、充填空間Mに充填された内容物を外界に向けて注出させることができる。 Further, FIG. 1 (a), in the example shown in FIG. 2 (a), and the claw portion 1c 6 on the outer wall surface of the distal end opening 1c 5 of the mouth portion 1c is formed, concentric from the top panel wall 2a to note decene 2 inner wall 2b is suspended in double arrangement, and an outer wall 2c is provided, is provided an inner wall 2b, and with inserting the claw portion 1c 6 in an annular recess formed between mutually outer wall 2c to the distal end of the outer wall 2c the pawl portion 2d is engaged with the claw portion 1c 6, are positioned and fixed Note decene 2 the mouth portion 1c. Further, a pouring hole 2e is provided in the central portion of the top wall 2a, and the contents filled in the filling space M can be poured out toward the outside.

キャップ3は、図1(a)、図2(a)に示すように、天面壁3aよりそれぞれ垂下される、内筒3bと、内筒3bを取り囲んで同心二重配置になる外筒3cとを備えている。内筒3bの内側壁部には、口部1cに設けた係合部nに適合する被係合部n´が形成されていて、容器本体1の口部1cにキャップ3を着脱自在にねじ止め保持することができる。また、内側壁部の先端には、図1(b)、図2(b)に示すように、キャップ3のねじ込み終了時に大凸部1cのストレート面と突き当たるストッパー3bと、小凸部1cと係合する弛み止め突起3bとが形成されている。図示の例では、2つのストッパー3bを互いに対向する位置に配置し、これらのストッパー3bから容器本体1と共通の軸線となるキャップ3の軸線を中心に90度ずらした位置に、2つの弛み止め突起3bを配設しているが、ストッパー3b、及び弛み止め突起3bは、それぞれ少なくとも1つ設けられていればよい。また、天面壁3aの中央部には、注出孔2eと適合する環状リブ3dが設けられており、キャップ3のねじ込み終了時には注出孔2eに入り込んで、充填空間Mを確実に密閉することができる。 As shown in FIGS. 1 (a) and 2 (a), the cap 3 includes an inner cylinder 3b suspended from the top wall 3a, and an outer cylinder 3c surrounding the inner cylinder 3b and having a concentric double arrangement. It has. An engaged portion n ′ that matches the engaging portion n provided in the mouth portion 1c is formed on the inner wall portion of the inner cylinder 3b, and the cap 3 can be removably screwed into the mouth portion 1c of the container body 1. Can be stopped and held. Further, the distal end of the inner wall portion, FIG. 1 (b), the as shown in FIG. 2 (b), the stopper 3b 1 impinging a straight surface of Daitotsu portion 1c 3 at the end screwing of the cap 3, small protrusions A slack prevention protrusion 3b 2 that engages with 1c 4 is formed. In the example shown in the figure, two stoppers 3b 1 are arranged at positions facing each other, and two stoppers 3b 1 are placed at positions shifted by 90 degrees from the stopper 3b 1 about the axis of the cap 3 serving as a common axis with the container body 1. Although arranged a locking projection 3b 2, stopper 3b 1, and locking projections 3b 2 only needs to be provided at least one, respectively. In addition, an annular rib 3d that is compatible with the pouring hole 2e is provided at the center of the top wall 3a, and enters the pouring hole 2e at the end of screwing of the cap 3 to securely seal the filling space M. Can do.

そして図示の例では、内筒3bに、その肉厚を部分的に薄肉にしたフラットな断面形状を有する薄肉部3bを設けていて、薄肉部3bの中間部に弛み止め突起3bが形成されている。これにより、内筒3bの肉厚が均一である場合に比して、弛み止め突起3bの周辺を容易に撓み変形させることができる。 In the illustrated example, the inner cylinder 3b is provided with a thin portion 3b 3 having a flat cross-sectional shape in which the thickness thereof is partially thinned, and the loosening projection 3b 2 is provided at an intermediate portion of the thin portion 3b 3. Is formed. This makes it possible in comparison with when the thickness of the inner cylinder 3b is uniform, thereby easily bending deformation of the periphery of the locking projection 3b 2.

さらに図示の例では、ストッパー3bの背面部にて、内筒3bと外筒3cとを相互につなぐ補強リブ3eを備えており、ストッパー3bを強固に保持している。 In yet illustrated example, at the rear portion of the stopper 3b 1, provided with reinforcing ribs 3e which connects the inner cylinder 3b and the outer tube 3c to each other, it is firmly held the stopper 3b 1.

上記のような構成となるキャップ付き容器において、キャップ3を容器本体1の口部1cにねじ止め固定するに当たっては、キャップ3を図1(b)、図2(b)に示すように矢印の向きに回転させる。キャップ3の回転が進むと、図示するように口部1cに設けた大凸部1cのストレート面にキャップ3のストッパー3bが突き当り、キャップ3のねじ込みが終了する。ここでねじ込みの終了直前においては、弛み止め突起3bが小凸部1cを乗り越える際に、内筒3b、特には薄肉部3bが撓み変形するので、小凸部1cと弛み止め突起3bとの削れを有効に抑制することができる。また、ねじ込み終了時においては、弛み止め突起3bと小凸部1cとは接触していて、弛み止め突起3bと小凸部1cとの相互間には接触圧が残った状態となっているので、キャップ3の弛みをより効果的に抑制してねじ込み終了姿勢を維持することができる。
特に、ストッパー3bの背面部に補強リブ3eを設ける場合には、キャップ3のねじ込みが所期する位置で確実に終了するため、小凸部1cと弛み止め突起3bとの相互間に隙間が生じることがなく確実に接触圧を残した状態にできるので、より有効にねじの弛みを抑えることができる。
なお、キャップ3を開栓する際に、弛み止め突起3bが大凸部1cに接触しても、弛み止め突起3bは大凸部1cの円弧状の曲面に沿って移動することになるので、開栓の妨げになくことがなく、キャップ3をスムーズに回転させることができる。
In the container with a cap configured as described above, when the cap 3 is screwed and fixed to the mouth portion 1c of the container body 1, the cap 3 is indicated by an arrow as shown in FIGS. 1 (b) and 2 (b). Rotate in the direction. When the rotation of the cap 3 progresses, the stopper 3b 1 of the cap 3 on the straight surface of the Daitotsu portion 1c 3 provided on the mouth part 1c as illustrated abuts, screwing of the cap 3 is completed. In just before the end of this case screwing, when the locking projection 3b 2 rides over the small protrusions 1c 4, the inner cylinder 3b, since in particular resiliently deformed thin-walled portion 3b 3, stop loosening the small protrusions 1c 4 projections Scraping with 3b 2 can be effectively suppressed. Further, at the time of screwing ends, the locking projection 3b 2 and the small convex portion 1c 4 in contact, between each other and locking protrusion 3b 2 and the small convex portion 1c 4 and a state in which the contact pressure remained Therefore, the loosening of the cap 3 can be more effectively suppressed and the screwing end posture can be maintained.
Particularly, in the case of providing the reinforcing ribs 3e to the rear portion of the stopper 3b 1, since the screwing of the cap 3 is reliably terminated to at a position where the desired, between each other and preventing projections 3b 2 slack and small protrusions 1c 4 Since it is possible to reliably maintain a contact pressure without generating a gap, it is possible to more effectively suppress loosening of the screw.
At the time of unplugging the cap 3, it locking projection 3b 2 is also in contact with the Daitotsu portion 1c 3, locking protrusions 3b 2 is moving along the arc-shaped curved surface of Daitotsu portion 1c 3 Therefore, the cap 3 can be smoothly rotated without obstructing the opening of the cap.

図3(a)、(b)に示すように、弛み止め突起3bの背面部にて、内筒3bと外筒3cとを相互につなぎ、内筒3bの撓み変形量を抑制する変形抑制リブ3fを設ける場合は、例えば内筒3bの先端を基準とする変形抑制リブ3fの先端までの距離(変形抑制リブ3fの高さ)を変更することによって、所期する撓み変形量を得ることができ、小凸部1cと弛み止め突起3bとの削れを抑制しつつ、不用意なキャップ3の開栓を防止することができる。また、変形抑制リブ3fの配設位置は、図示するように弛み止め突起3bの真後ろに設ける場合だけに限られず、例えば、弛み止め突起3bから間隔をおいて弛み止め突起3bを2つ配置し、2つの弛み止め突起3bで両端支持するようにしてもよく、弛み止め突起3bからの間隔に応じて、所期する撓み変形量を得ることもできる。 FIG. 3 (a), (b), the at rear portion of the locking projection 3b 2, connecting the inner cylinder 3b and the outer tube 3c to each other, suppressing deformation suppressing bending deformation of the inner cylinder 3b In the case of providing the rib 3f, for example, by changing the distance (height of the deformation suppression rib 3f) to the tip of the deformation suppression rib 3f with reference to the tip of the inner cylinder 3b, an expected amount of bending deformation is obtained. can be, while suppressing abrasion of the stop projection 3b 2 slack and small protrusions 1c 4, it is possible to prevent unplugging inadvertent cap 3. Further, the arrangement position of the deformation suppressing rib 3f is not limited to the case where the deformation suppressing rib 3f is provided just behind the anti-loosening projection 3b 2 , as shown in the figure. For example, the anti-loosening projection 3b 2 is spaced by 2 from the anti-loosening projection 3b 2 . The two ends may be supported by the two locking protrusions 3b 2 , and the desired amount of bending deformation can be obtained according to the distance from the locking protrusions 3b 2 .

また、図4(a)、(b)に示すように、内筒3bと外筒3cとを同心二重配置にしてそれらを天面壁3aに連結した一体型のキャップ3に代えて、内キャップ31と外キャップ32とで構成される組み合わせ型のキャップ30を用いることもできる。図示の例で内キャップ31の内側壁部には、前述の内筒3bと同様に、被係合部n´、ストッパー3b、及び弛み止め突起3bが形成されており、外側壁部には、爪部31aが設けられていて、外キャップ32の内側壁部に設けた凸部32aと係合させて、相互に連結させている。また図示の例では、外キャップ32から、ストッパー3bの背面部に向けて突設する補強リブ32bを設けてストッパー3bを支持することで、上記補強リブ3eと同様の効果を与えているが、この補強リブ32bに代えて、ストッパー3bの背面部から外キャップ32の内壁面に向けて突設するリブを設けてもよい。さらに、外キャップ32から弛み止め突起3bの背面部に向けて突設して、内キャップ31の撓み変形量を抑制する変形抑制リブを設けてもよく、またこの変形抑制リブは、外キャップ32からの突設に代えて弛み止め突起3bの背面部から外キャップ32の内壁面に向けて突設するものであってもよい。なお、内キャップ31と外キャップ32との相互間には、図示しない回り止め機構(例えば内キャップ31の内側壁部に凹部を設け、外キャップ32の外側壁部に、この凹部に適合する凸部を設ける)が設けられているので、外キャップ32の回動に応じて内キャップ31も回動することができる。ここで容器本体1は、ガラスとすることもできるが、樹脂材料を用いる場合は、容器本体1の樹脂材料(例えばPET)よりも硬度の高い樹脂材料(例えばPOM、PBT、Ny)を内キャップ31に使用して小凸部1cとの削れに対する耐久性を向上させるとともに、外キャップ32は装飾性に優れる材料を採用することができる。 Further, as shown in FIGS. 4 (a) and 4 (b), an inner cap 3b and an outer tube 3c are arranged in a concentric double arrangement, and the inner cap 3 is connected to the top wall 3a. A combined cap 30 composed of 31 and an outer cap 32 can also be used. In the illustrated example, an engaged portion n ′, a stopper 3b 1 , and a locking protrusion 3b 2 are formed on the inner wall portion of the inner cap 31 in the same manner as the inner cylinder 3b described above. Is provided with a claw portion 31a, and is engaged with a convex portion 32a provided on the inner wall portion of the outer cap 32 so as to be connected to each other. In the illustrated example, the outer cap 32, by supporting the stopper 3b 1 provided reinforcing ribs 32b which protrude toward the rear portion of the stopper 3b 1, giving the same effect as the reinforcing ribs 3e but in place of the reinforcing ribs 32b, the rear portion of the stopper 3b 1 may be provided with ribs to protrude toward the inner wall surface of the outer cap 32. Further, a deformation suppression rib that protrudes from the outer cap 32 toward the back surface of the loosening prevention protrusion 3b 2 and suppresses the amount of deformation of the inner cap 31 may be provided. Instead of projecting from 32, it may project from the back surface portion of the locking projection 3 b 2 toward the inner wall surface of the outer cap 32. In addition, between the inner cap 31 and the outer cap 32, a non-illustrated anti-rotation mechanism (for example, a concave portion is provided in the inner wall portion of the inner cap 31 and the outer wall portion of the outer cap 32 is provided with a convex portion adapted to the concave portion. Since the outer cap 32 is rotated, the inner cap 31 can also be rotated. Here, the container body 1 can be made of glass, but when a resin material is used, a resin material (for example, POM, PBT, Ny) having a higher hardness than the resin material (for example, PET) of the container body 1 is used as the inner cap. It improves the durability against abrasion between the small convex portion 1c 4 using the 31, the outer cap 32 may be employed materials having excellent decorative properties.
