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 portion 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.
JP-A-11-49211

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 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、周壁２の前端部2a以外を内壁2b及び外壁2cからなる内外二重壁で構成し、前端部2aの両端からそれぞれ周壁２の前半部両端に至る部分の二重壁上端縁に易切断性の薄肉壁８を一体に掛け渡してなり、外壁2cの後部上端部と蓋体A2の後部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 hinge cap is composed of an inner / outer double wall composed of an inner wall 2b and an outer wall 2c other than the front end 2a of the peripheral wall 2 and is formed from both ends of the front end 2a. each becomes spanned integrally easy-to-break of the thin wall 8 double-walled upper edge portion extending in the first half ends of the peripheral wall 2, the a rear upper and rear lower end portion of the lid a 2 of the outer wall 2c They were connected by a 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、薄肉壁８の後方の内壁2bと外壁2cとの間を周方向複数の易切断性の連結片９により連結した。   The second means is configured as follows. That is, in the first means, the inner wall 2b and the outer wall 2c behind the thin wall 8 are connected by a plurality of easily cut connecting pieces 9 in the circumferential direction.

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、周壁２の前端部2a両端近傍の内壁2b内面に、それぞれ凹溝10を縦設した。
The third means was configured as follows. That is, in either the first means or the second means , the concave grooves 10 are vertically provided on the inner surface of the inner wall 2b in the vicinity of both ends of the front end portion 2a of the peripheral wall 2 , respectively.

本発明のヒンジキャップは、周壁２の前端部2a以外を内壁2b及び外壁2cからなる内外二重壁で構成し、前端部2aの両端からそれぞれ前半部に至る部分の二重壁上端縁に易切断性の薄肉壁８を一体に掛け渡してなり、外壁2cの後部上端部と蓋体A2の後部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。また、キャップ本体A1の前半部は、周壁２の前端部2a及び薄肉壁８で覆われているため、注出液が二重壁内に浸入するのを極力防止できる利点もある。 The hinge cap of the present invention is configured by an inner / outer double wall composed of an inner wall 2b and an outer wall 2c other than the front end 2a of the peripheral wall 2, and is easily formed on the upper end edge of the double wall from both ends of the front end 2a to the front half. the cutting of the thin wall 8 becomes spanned together, since a rear lower portion of the rear upper portion and the lid a 2 of the outer wall 2c and connected by the hinge mechanism, has become easier operation to break the cap After use, the open lid A 2 can be easily detached from the container B by pulling up the upper lid strongly. In addition, since the front half of the cap body A 1 is covered with the front end 2a of the peripheral wall 2 and the thin wall 8, there is an advantage that the poured liquid can be prevented from entering the double wall as much as possible.

薄肉壁８の後方の内壁2bと外壁2cとの間を周方向複数の易切断性の連結片９により連結した場合には、外壁2c自体の保形性に加えて各連結片９により保形性を付与できるため、通常操作時に外壁2c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 2b and the outer wall 2c at the rear of the thin wall 8 are connected by a plurality of easily cutable connecting pieces 9 in the circumferential direction, the shape is maintained by the connecting pieces 9 in addition to the shape-holding property of the outer wall 2c itself. Therefore, inconveniences such as deformation of the outer wall 2c during normal operation can be prevented more reliably.

周壁２の前端部2a両側の内壁2b内面にそれぞれ凹溝10を縦設した場合には、蓋体A2を上方へ引き上げてキャップ本体A1を容器体口頸部100 より取り外そうとする際に、前端部2aの外方への変形を起こし易く、その結果、より容易なキャップ本体A1の取り外しが可能となる。 When the respective front end portion 2a on both sides of the inner wall 2b inner surfaces of the peripheral wall 2 and Tate設the grooves 10, Any attempt to remove the cap body A 1 from the container body mouth neck 100 by pulling the lid A 2 upward when, susceptible to deformation outward of the front end portion 2a, as a result, it is possible to easier removal of the cap body a 1.

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５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 5 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、前端部2a以外を内壁2b及び外壁2cからなる内外二重壁で構成している。また、前端部2aの両端からそれぞれ前半部に至る部分の二重壁上端縁に易切断性の薄肉壁８を一体に掛け渡している。   The peripheral wall 2 is constituted by an inner / outer double wall including an inner wall 2b and an outer wall 2c except for the front end 2a. Further, an easily cut thin wall 8 is integrally stretched around the upper end edge of the double wall from both ends of the front end portion 2a to the front half portion.

また、薄肉壁８の後方の内壁2bと外壁2cとの間を周方向間隔をあけた複数の易切断性の連結片９により連結している。尚、この連結片９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上端部に設ける場合に限らず、下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、上端部に設けた場合には、各連結片９の間を薄肉壁で閉塞することも可能である。   Further, the inner wall 2b and the outer wall 2c on the rear side of the thin wall 8 are connected by a plurality of easily cut connecting pieces 9 spaced in the circumferential direction. Although the connecting piece 9 is not necessarily provided, the initial purpose can be achieved, but the provision of the connecting piece 9 exhibits the above-described advantages. In addition, the formation position is not limited to the case of being provided at the upper end as in this example, and a plurality of formation positions may be provided with a circumferential interval at the lower end, or a plurality with a circumferential interval at the upper and lower intermediate portions. May be. Furthermore, when it is provided at the upper end, it is possible to close between the connecting pieces 9 with a thin wall.

また、前端部2a両側の内壁2b内面にそれぞれ凹溝10を縦設している。これにより、キャップ本体A1を取り除く際に前端部2aの変形を行い易くしており、それに伴って、係止突条101 と係合突条４の係合が外れ易くなる如く構成している。 In addition, a concave groove 10 is provided vertically on the inner surface of the inner wall 2b on both sides of the front end portion 2a. Thus, has facilitated the deformation of the front end portion 2a in removing the cap body A 1, along with it, the engagement of the locking projections 101 and the engagement projection 4 is constituted as easily disengaged .

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2c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2c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。尚、ヒンジ機構としては本例のものに限らず、例えば、薄肉ヒンジのみで構成されたものを採用してもよく、この種のヒンジキャップで採用される公知のヒンジ機構を採用できる。 The lid A 2 has a rear lower end rotatably connected to a rear upper end of the cap main body A 1 via a hinge mechanism, 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 of the peripheral wall 30 and the cap body A 1 of the outer wall 2c are connected by thin hinge 34, in the both sides, a pair of elastic plates between the wall 30 and the outer wall 2c 35 is connected, and elastic reversal is possible. Note that the hinge mechanism is not limited to the one in this example, and, for example, a mechanism composed only of a thin-walled hinge may be employed, and a known hinge mechanism employed in this type of hinge cap can be employed.

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2cが上方へ引き上げられる。この際、各連結片９が破断し、また、薄肉壁８が破断して前端部2aの両側位置から立ち上がる状態となり、また、外壁2cは前端部2aと比較して薄肉に形成されているため強い力で立ち上がらせた際に捩じれる如く変形して前端部2a前方まで回動させることができ、前端部2a部分の係止突条101 と係合突条４との係合を簡単に解除することができる。次いで、その状態から蓋体A2を更に引き上げれば、キャップ本体A1を簡単に口頸部100 より取り外すことができる。 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 2c is pulled upward. At this time, each connecting piece 9 breaks, the thin wall 8 breaks and rises from both side positions of the front end 2a, and the outer wall 2c is formed thinner than the front end 2a. It can be deformed to be twisted when it is raised with a strong force and can be rotated to the front of the front end 2a, and the engagement of the locking protrusion 101 and the engaging protrusion 4 at the front end 2a can be easily released. can do. Next, when the lid A 2 is further pulled up from this state, the cap body A 1 can be easily removed from the mouth-and-neck portion 100.
