Description

本発明はヒンジキャップに関し、詳しくは、装着した容器体からの分別廃棄を容易に行えるヒンジキャップに関する。 The present invention relates to a hinge cap, and more particularly to a hinge cap that can be easily disposed of from a mounted container body.

キャップ本体と蓋体とをヒンジ連結して合成樹脂により一体に成形したヒンジキャップが種々提案されている。これらは容器の口部にキャップ本体の周壁を嵌合させ、突条相互の乗り越え係合等の手段により抜け出し防止を図っている。また、これらのキャップでは、諸事情により容器体との分別処理が一般に行われているが、通常の上記係合手段により係止されたキャップ本体は外れ難いという問題があった。係合手段の係合強度を小さくすればそのような問題も解決するが、今度は使用中にキャップ本体がズレたり、外れたりする不都合が生じる。 Various types of hinge caps have been proposed in which a cap body and a lid are hinge-connected and integrally formed of synthetic resin. In these cases, the peripheral wall of the cap main body is fitted to the mouth of the container, and is prevented from coming out by means such as overriding engagement between the protrusions. Moreover, in these caps, although the separation process with a container body is generally performed by various circumstances, there existed a problem that the cap main body latched by the normal said engagement means was hard to remove | deviate. Such a problem can be solved by reducing the engagement strength of the engagement means, but this time, there arises a problem that the cap body is displaced or detached during use.

そこで、使用中には強固に容器体に嵌合し、使用後には簡単に容器体から外れるヒンジキャップが種々提案されている。（特許文献１参照） Therefore, various hinge caps have been proposed that fit firmly into the container body during use and can be easily detached from the container body after use. (See Patent Document 1)

上記ヒンジキャップは、頂板部と頂板部周縁から垂下している筒状側壁とを有するキャップ本体と、該キャップ本体の筒状側壁上端部にヒンジ連結された上蓋とから成るヒンジキャップであって、キャップ本体の筒状側壁の一部分は、その上端から外側側壁とに分割され、該内側側壁と外側側壁とは、スリットの部分で互いに対面しているが下方部分及び両側部分では互いに一体に連なっているとともに、外側側壁の上端に上蓋ヒンジが連結されて構成されている。 The hinge cap is a hinge cap comprising a cap body having a top plate portion and a cylindrical side wall depending from the periphery of the top plate portion, and an upper lid hinged to the upper end of the cylindrical side wall of the cap body, A portion of the cylindrical side wall of the cap body is divided into an outer side wall from the upper end, and the inner side wall and the outer side wall face each other at the slit portion, but are continuous with each other at the lower portion and both side portions. In addition, an upper lid hinge is connected to the upper end of the outer side wall.

そして、上蓋を開栓した状態で、上蓋を横方向に引っ張る。これにより、スリットの両端部分から外側側壁は引き裂かれるので、これを下方に押し下げることにより、外側側壁の両側はスリットの両端部分に沿って下端まで引き裂かれる状態で、引き裂かれた外側側壁或いは上蓋を上方に引っ張り上げると、薄肉となっている内側側壁は下端から容易に捲くり上げられ、この部分で容器口部との係合が解除されるので、キャップ本体を容易に容器口部から取り外すことができる。
特開平１１−４９２１１号公報 Then, with the upper lid opened, the upper lid is pulled laterally. As a result, the outer side wall is torn from the both end portions of the slit.By pushing down, the both sides of the outer side wall are torn to the lower end along the both end portions of the slit, and the torn outer side wall or upper lid is removed. When pulled upward, the thin inner side wall is easily rolled up from the lower end, and the engagement with the container mouth is released at this part, so the cap body can be easily removed from the container mouth. Can do.

上記ヒンジキャップは上記した如く、廃棄の際に容易に容器口部から取り外すことができる優れたものであるが、その開封手順が、上蓋を横方向及び下方向に引っ張るものであるため複雑で、引き裂きずらい面があった。 As described above, the hinge cap is an excellent one that can be easily removed from the container mouth at the time of disposal, but its opening procedure is complicated because it pulls the upper lid laterally and downward, There was a difficult side to tear.

本発明は上記した点に鑑みてなされたもので、通常の使用操作時には取り外し手段に及ぼす影響が極めて少なく、使用中には確実に容器体に嵌合して嵌合が弛んだりズレたりする虞れがなく、しかも、使用後には簡単に容器体から取り外して分別処理を行うことができるヒンジキャップを提案する。 The present invention has been made in view of the above points, and has an extremely small influence on the detaching means during a normal use operation, and there is a possibility that the fitting is surely fitted into the container body and the fitting is loosened or displaced during use. In addition, the present invention proposes a hinge cap that can be easily removed from the container body and separated after use.

第１の手段として、以下の通り構成した。即ち、容器体口頸部100 外周に周壁２を嵌合させるとともに、周壁２内周に突設した係合突条４を容器体口頸部100 外周の係止突条101 に乗り越え係合させて抜け出しの防止を図ったキャップ本体A₁と、キャップ本体A₁の後部上端にヒンジ機構を介して後部下端を回動可能に連結するとともに、キャップ本体A₁上を開閉可能に設けた蓋体A₂とを備え、全体を合成樹脂により一体に形成したヒンジキャップであって、環状の周壁２を、前半部2aと、内壁10及び外壁11の内外二重壁を両端の端壁12でそれぞれ連結した後半部2bとで構成し、且つ、前半部2aと後半部2bとの小間隙13を易切断性の薄肉連結壁14によりそれぞれ連結して構成し、外壁11上端部と蓋体A₂下端部とを上記ヒンジ機構で連結した。 The first means is configured as follows. That is, the peripheral wall 2 is fitted to the outer periphery of the container body neck portion 100, and the engaging protrusion 4 projecting from the inner periphery of the peripheral wall 2 is moved over the engaging protrusion 101 on the outer periphery of the container body neck portion 100. A cap body A ₁ that prevents slipping out, and a lid body that pivotally connects the lower end of the rear end of the cap body A ₁ via a hinge mechanism to the upper end of the cap body A ₁ and that can be opened and closed on the cap body A ₁ A hinge cap comprising A ₂ and integrally formed of synthetic resin, the annular peripheral wall 2, the front half 2a, and the inner and outer double walls of the inner wall 10 and the outer wall 11 at the end walls 12 at both ends, respectively. The rear half 2b is connected, and the small gap 13 between the front half 2a and the rear half 2b is connected by an easily cut thin connecting wall 14, respectively, and the upper end of the outer wall 11 and the lid A ₂ The lower end part was connected with the hinge mechanism.

第２の手段として、以下の通り構成した。即ち、前記第１の手段に於いて、後半部2bに於ける係合突条４と係止突条101 との係合強度を、前半部2aに於ける係合突条４と係止突条101 との係合強度より小とした。 The second means is configured as follows. That is, in the first means, the engagement strength between the engagement protrusion 4 and the engagement protrusion 101 in the rear half 2b is set to be equal to the engagement protrusion 4 and the engagement protrusion in the front half 2a. The engagement strength with the article 101 was made smaller.

第３の手段として、以下の通り構成した。即ち、前記第１の手段又は第２の手段のいずれかの手段に於いて、内壁10と外壁11との間を周方向複数の易切断性の連結片15により連結した。 The third means was configured as follows. In other words, in either the first means or the second means, the inner wall 10 and the outer wall 11 are connected by a plurality of easily cut connecting pieces 15 in the circumferential direction.

本発明のヒンジキャップは、環状の周壁２を、前半部2aと、内壁10及び外壁11の内外二重壁を両端の端壁12でそれぞれ連結した後半部2bとで構成し、且つ、前半部2aと後半部2bとの小間隙13を易切断性の薄肉連結壁14によりそれぞれ連結して構成し、外壁11上端部と蓋体A₂下端部とを上記ヒンジ機構で連結したので、キャップを破断する操作が容易になっており、使用後には開いた蓋体A₂を上方に力強く引き上げることにより簡単に容器体Ｂより取り外すことができる。 In the hinge cap of the present invention, an annular peripheral wall 2 is constituted by a front half 2a and a rear half 2b in which inner and outer double walls of an inner wall 10 and an outer wall 11 are connected by end walls 12 at both ends, and the front half Since the small gap 13 between 2a and the rear half 2b is connected by an easily cut thin connecting wall 14, and the upper end of the outer wall 11 and the lower end of the lid A ₂ are connected by the hinge mechanism, the cap is The operation of breaking is easy, and after use, the opened lid A ₂ can be easily removed from the container B by pulling up the lid strongly.

また、後半部2bに於ける係合突条４と係止突条101 との係合強度を、前半部2aに於ける係合突条４と係止突条101 との係合強度より小とした場合には、キャップ取り外しに当たり、特に最初に係合が外れる部分である後半部の係合強度が小さいためより外れ易くなる。 Further, the engagement strength between the engagement protrusion 4 and the locking protrusion 101 in the rear half 2b is smaller than the engagement strength between the engagement protrusion 4 and the engagement protrusion 101 in the front half 2a. In this case, when the cap is removed, the engagement strength of the latter half, which is the part where the engagement is first released, is small, so that it becomes easier to come off.

内壁10と外壁11との間を周方向複数の易切断性の連結片15により連結した場合には、外壁11自体の保形性に加えて各連結片15による保形性を付与できるため、通常操作時に外壁11が変形する等の不都合をより確実に防止できる。 When the inner wall 10 and the outer wall 11 are connected by a plurality of easily cleavable connecting pieces 15 in the circumferential direction, in addition to the shape retaining properties of the outer wall 11 itself, the shape retaining properties by each connecting piece 15 can be imparted, Inconveniences such as deformation of the outer wall 11 during normal operation can be prevented more reliably.

以下、本発明の実施例の形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１乃至図４は本発明のキャップＡの一例を示すもので、キャップＡは、キャップ本体A₁と、蓋体A₂とから構成されている。 1 to 4 show an example of a cap A according to the present invention, and the cap A is composed of a cap body A ₁ and a lid A ₂ .

キャップ本体A₁は、容器体Ｂの口頸部100 外周に嵌合させる周壁２の上端縁より頂壁３を延設している。周壁２の内周下部には係合突条４を突周設しており、容器体Ｂの口頸部100 外周に突周設した係止突条101 に係合突条４を乗り越え係合させて上方への抜け出し防止を図っている。 The cap body A ₁ has a top wall 3 extending from the upper end edge of the peripheral wall 2 to be fitted to the outer periphery of the mouth neck portion 100 of the container body B. An engaging protrusion 4 is provided on the inner peripheral lower portion of the peripheral wall 2 so that the engaging protrusion 4 is engaged with the engaging protrusion 101 provided on the outer periphery of the neck portion 100 of the container B. In this way, it prevents the upward slipping out.

頂壁３は容器体口頸部100 内周上端部に液密に嵌合するシール部3aを外周部に形成しており、また、中央部には注出筒部５を立設し、注出筒部５内には線状の薄肉部６により囲成される除去壁部3bを画成している。更に、除去壁部3b上面よりプルリング７を立設している。 The top wall 3 is formed with a seal portion 3a that is liquid-tightly fitted to the inner peripheral upper end portion of the container body neck portion 100, and a pouring tube portion 5 is erected at the center portion. A removal wall portion 3b surrounded by a linear thin-walled portion 6 is defined in the outlet tube portion 5. Further, a pull ring 7 is erected from the upper surface of the removal wall 3b.

周壁２は、前半部2aと、後半部2bとで構成されており、前半部2aは中実の半環状壁であるのに対し、後半部2bは、内壁10と外壁11とをその両端部において端壁12によりそれぞれ連結した中空半環状壁に構成している。本例では、後半部2bに於ける係合突条４と係止突条101 との係合強度を、前半部2aに於ける係合突条４と係止突条101 との係合強度より小として構成している。この様に構成するためには、例えば、係合突条４の突出幅や高さを調整することにより現出することができる。 The peripheral wall 2 is composed of a front half 2a and a rear half 2b. The front half 2a is a solid semi-annular wall, whereas the rear half 2b has an inner wall 10 and an outer wall 11 at both ends thereof. In FIG. 2, the hollow semi-annular walls are connected by the end walls 12 respectively. In this example, the engagement strength between the engagement protrusion 4 and the locking protrusion 101 in the rear half 2b is the same as the engagement strength between the engagement protrusion 4 and the engagement protrusion 101 in the front half 2a. Configure as smaller. In order to constitute in this way, for example, it can appear by adjusting the protrusion width and height of the engaging protrusion 4.

また、前半部2aと後半部2bとの小間隙13を、内外を閉塞するための易切断性の薄肉連結壁14により連結している。更に、内壁10と外壁11とは下端部に於いて、周方向間隔をあけた複数の易切断性の連結片15により連結している。尚、この連結片15は必ずしも設けなくても初期の目的を達成できるが、設けることにより上記した利点を発揮する。また、その形成位置も本例の如く下端部に設ける場合に限らず、上端部に周方向間隔をあけて複数設けても良く、或いは上下中間部に於いて、周方向間隔をあけて複数設けても良い。更に、この連結片15に代えて、内壁10と外壁11の上端開口を閉塞して、薄肉で易切断性の連結壁を掛け渡しても良い。この場合も、上端部に限らず下端部に掛け渡し手も、或いは中間部に掛け渡しても良い。また、連結片と連結壁とを併用することも可能である。 The small gap 13 between the front half 2a and the rear half 2b is connected by an easily cut thin connecting wall 14 for closing the inside and outside. Furthermore, the inner wall 10 and the outer wall 11 are connected at the lower end portion by a plurality of easily cut connecting pieces 15 spaced in the circumferential direction. Although the connecting piece 15 is not necessarily provided, the initial purpose can be achieved, but the provision of the connecting piece 15 exhibits the above-described advantages. In addition, the formation position is not limited to the case of being provided at the lower end portion as in this example, and a plurality of upper end portions may be provided with a circumferential interval, or a plurality of circumferential positions may be provided at the upper and lower intermediate portions. May be. Further, instead of the connecting piece 15, the upper end openings of the inner wall 10 and the outer wall 11 may be closed, and a thin and easily cut connecting wall may be hung. Also in this case, not only the upper end portion but also a hand extending to the lower end portion or an intermediate portion may be used. Moreover, it is also possible to use a connection piece and a connection wall together.

蓋体A₂は、キャップ本体A₁の後部上端にヒンジ機構を介して後部不端を回動可能に連結するとともに、キャップ本体A₁上を開閉可能に設けている。図示例では、周壁30の上端縁より頂壁31を延設した下端開口の有頂筒状をなし、キャップ本体A₁の上面周縁部に周壁30下端部を嵌合可能に構成している。頂壁31裏面からは注出筒部５に液密に嵌合するシール筒32を垂設し、周壁30の前面からは指掛け突起33を突設している。また、ヒンジ機構として、周壁30の後部下端とキャップ本体A₁の外壁11の後部上端とを薄肉ヒンジ34により連結し、その両側に於いて、周壁30と外壁11との間に一対の弾性板35を掛け渡し、弾性反転が可能に連結している。 The lid A ₂ is connected to the rear upper end of the cap main body A ₁ via a hinge mechanism so as to be rotatable, and the cap main body A ₁ can be opened and closed. In the illustrated example, it forms a closed top cylindrical lower end opening to extend the top wall 31 than the upper edge of the peripheral wall 30, and can fit to constitute a peripheral wall 30 the lower end to the top rim portion of the cap body A _1. From the back surface of the top wall 31, a seal cylinder 32 that is liquid-tightly fitted to the extraction cylinder portion 5 is suspended, and a finger hooking protrusion 33 is projected from the front surface of the peripheral wall 30. Further, as a hinge mechanism, a rear upper end of the rear lower end cap body A ₁ of the outer wall 11 of the peripheral wall 30 connected by thin hinge 34, in the both sides, a pair of elastic plates between the wall 30 and the outer wall 11 35 is connected, and elastic reversal is possible.

上記の如く構成したキャップＡは、使用に当たりプルリング７を引き上げて線状の薄肉部６を切断し、除去壁部3bを取り除いて注出口を開口し、そこから容器体Ｂ内の液を注出する。また、内容液を使用した後廃棄の際には、蓋体A₂を開いた状態で上方へ強く引くと、外壁11が上方へ引き上げられる。この際、各連結片15が破断し、また、薄肉連結壁14が破断するため、両側の端壁12により内壁10も外方へ捲くり上げる様に引っ張られて係合突条４と係止突条101 の係合が部分的に外れ、或いは外れかかり、キャップ本体A₁を口頸部100 から容易に取り外すことができる。また、外壁11は半環状に構成されているため、引き上げに際してキャップ本体の他部分に引っ掛かる等の不都合がなく、力を効率良く伝達できる。 In use, the cap A constructed as described above pulls up the pull ring 7 to cut the linear thin-walled portion 6, removes the removal wall portion 3b, opens the spout, and pours the liquid in the container body B therefrom. To do. At the time of disposal after use the contents liquid is pulled strongly upward with open lid A _2, the outer wall 11 is pulled upward. At this time, each connecting piece 15 breaks and the thin-walled connecting wall 14 breaks. Therefore, the inner wall 10 is pulled up by the end walls 12 on both sides to be locked to the engaging protrusion 4. The engagement of the ridge 101 is partially disengaged or disengaged, and the cap body A ₁ can be easily removed from the mouth-and-neck portion 100. Further, since the outer wall 11 is formed in a semi-annular shape, there is no inconvenience such as being caught on the other part of the cap main body when being pulled up, and the force can be transmitted efficiently.
