Description

本発明は、主に一般家庭で使用される手動のペットボトル等の容器の蓋開け具に関する。 The present invention relates to a lid opening device for containers such as manual PET bottles mainly used in general households.

容器の蓋を容易に開けるための蓋開け具であって、複数の爪部材が蓋受容部領域に突出して蓋の外周面を圧接し、その圧接の摩擦力等によって蓋を緩めて取り外す蓋開け具は、例えば、特開２００３−１３７３９３号公報に開示されている。ここに記載されている蓋開け具は、上部材である握り部と、可動部材である把持基台の２つの部材から成り、この点で３つの部材から成る本発明と異なっている。この文献の爪部材である挟持材は、その一端が把持基台に支軸により回動可能に軸支されている。そして、この文献の明細書及び図面の記載では、握り部の下端部には凹部が形成されており、把持基台の上部には凸部が形成され、これら凹部と凸部とが互いに摺動自在に嵌合している。したがって、握り部と蓋把持部の把持基台とは、離脱することなく互いに摺動可能である、という内容の記載がある。確かに、握り部と蓋把持部の把持基台とは、凹凸の関係で結合されているので離脱することなく互いに摺動可能であるが、このように、凸部が形成された握り部と凹部が形成された蓋把持部とを嵌合させるための構成について記載がない。図面から判断すれば、握り部と把持基台とを硬質樹脂で変形不能に形成したときに、凹部と凸部とを嵌合させることは不可能である。仮に、把持基台を変形可能なやや柔軟性を有する合成樹脂で形成すれば嵌合は可能である。しかし、柔軟性を有する合成樹脂は摩擦係数が大きいので、握り部に嵌合している把持基台を容易に回転させることができない。また、容器の蓋の外周面に圧接させた挟持材の反力によって、柔軟性を有する把持基台が押されて変形し、操作中に握り部から外れる虞もある。また、凸部を複数の周方向に短い凸部にするなどして凹部に嵌合できることも考えられるが、そのようにすると、嵌合が容易に外れてしまうことになる。 A lid opening tool for easily opening the lid of a container, wherein a plurality of claw members project into the lid receiving portion region and press the outer peripheral surface of the lid, and the lid opening tool that loosens and removes the lid by the frictional force of the pressing is a For example, it is disclosed by Unexamined-Japanese-Patent No. 2003-137393. The lid opening tool described here is composed of two members, ie, a grip portion which is an upper member and a grip base which is a movable member, and differs from the present invention which is composed of three members in this respect. One end of the clamping member, which is a claw member of this document, is pivotally supported by a holding base so as to be rotatable by a support shaft. In the specification and drawings of this document, a concave portion is formed at the lower end portion of the grip portion, a convex portion is formed at the upper portion of the grip base, and the concave portion and the convex portion slide with each other. Fits freely. Accordingly, there is a description that the grip portion and the grip base of the lid grip portion can slide with respect to each other without being detached. Certainly, the gripping part and the grip base of the lid gripping part are slidably connected to each other without being separated because they are connected in a concavo-convex relationship. There is no description about the structure for fitting with the lid | cover holding part in which the recessed part was formed. Judging from the drawings, when the grip portion and the grip base are formed of a hard resin so as not to be deformed, it is impossible to fit the concave portion and the convex portion. If the grip base is made of a deformable synthetic resin that can be deformed, fitting is possible. However, since the synthetic resin having flexibility has a large coefficient of friction, the grip base that is fitted to the grip portion cannot be easily rotated. In addition, the gripping base having flexibility may be pushed and deformed by the reaction force of the clamping material pressed against the outer peripheral surface of the lid of the container, and may be detached from the grip portion during operation. Further, it is conceivable that the convex portion can be fitted into the concave portion by making the convex portion short in a plurality of circumferential directions, but if so, the fitting is easily disengaged.

特許文献１についてさらに言えば、この文献の図１に記載された第一実施例は、把持基台と挟持材と押圧棒の３つのリンクからなる三節回転機構であり、このような機構は拘束連鎖と呼ばれ、各リンク間の相対運動は不可能である。したがって、図１に記載された挟持材は固定されており、蓋に接近することができず、実施不能である。 Speaking further about Patent Document 1, the first embodiment shown in FIG. 1 of this document is a three-bar rotation mechanism comprising three links of a gripping base, a sandwiching material, and a pressing rod. It is called a chain, and relative movement between links is impossible. Therefore, the clamping material described in FIG. 1 is fixed, cannot approach the lid, and cannot be implemented.

本発明は、爪部材の動きを円滑にして、爪部材の爪端を容器の蓋に迅速に圧接させ、蓋を確実に回転させ取り外すことができる手動式の蓋開け具を提供することを目的とする。 It is an object of the present invention to provide a manual lid opening device that can smoothly move the claw member, quickly press the claw end of the claw member against the lid of the container, and reliably rotate and remove the lid. To do.

本発明は、直接的に結合された上部材と下部材、及びそれらの部材に対して両部材の間で可動に挟持された可動部材を含み、容器の蓋を下側から挿入させる蓋受容部を有し、下部材には、この蓋受容部の開口部が形成され、複数の爪部材が、上部材と下部材の間に取り付けられており、各爪部材は、上下方向に延びる回転軸線を中心に所定の範囲内で回転可能であり、蓋を緩めるように可動部材に力を加えたときに、その力を爪部材に伝えて爪部材を回転させることにより、爪部材の爪端を蓋の外周面に圧接させるための機構を有し、容器の蓋を蓋受容部に挿入する際に、当初は、蓋の外周面から距離を置いて該外周面の周囲に位置している爪端が、蓋受容部に挿入されつつある蓋からの反力によって、蓋の外周面に接触するまで移動させる手段を備えており、その手段は、爪部材に形成された突出部であって、該突出部は、爪部材の回転軸線から爪端に引いた直線方向と異なる方向へ突出するように形成され、突出部は、蓋受容部に挿入された蓋の方向を向く外周面を有し、該外周面は、突出部がその下面から上面に行くに従って徐々に外周面の外周を広げるように、突出部の下面から上面に行くに従って徐々に外側に広がる傾斜面に形成されている構成である。 The present invention includes an upper member and a lower member that are directly coupled to each other, and a movable member that is movably sandwiched between both members with respect to these members, and a lid receiving portion that allows a lid of a container to be inserted from below. The lower member has an opening of the lid receiving portion, a plurality of claw members are attached between the upper member and the lower member, and each claw member has a rotation axis extending in the vertical direction. is rotatable within a predetermined mainly, when a force is applied to the movable member so as to loosen the lid, by rotating the pawl member to convey the force to the pawl member, the pawl end of the pawl member A claw having a mechanism for press-contacting with the outer peripheral surface of the lid, and initially located around the outer peripheral surface at a distance from the outer peripheral surface of the lid when inserting the lid of the container into the lid receiving portion The end is moved until it comes into contact with the outer peripheral surface of the lid by a reaction force from the lid being inserted into the lid receiving portion. The protrusion is formed on the claw member, and the protrusion is formed to protrude in a direction different from the linear direction drawn from the rotation axis of the claw member to the end of the claw. The protruding portion has an outer peripheral surface facing the direction of the lid inserted into the lid receiving portion, and the outer peripheral surface protrudes so as to gradually widen the outer periphery of the outer peripheral surface from the lower surface to the upper surface. It is the structure formed in the inclined surface which spreads outside gradually as it goes to the upper surface from the lower surface of a part.

本発明は、直接的に結合された上部材と下部材、及びそれらの部材に対して両部材の間で可動に挟持された可動部材を含み、容器の蓋を下側から挿入させる蓋受容部を有し、下部材には、この蓋受容部の開口部が形成され、複数の爪部材が、上部材と下部材の間に取り付けられており、各爪部材は、上下方向に延びる回転軸線を中心に所定の範囲内で回転可能であり、蓋を緩めるように可動部材に力を加えたときに、その力を爪部材に伝えて爪部材を回転させることにより、爪部材の爪端を蓋の外周面に圧接させるための機構を有し、容器の蓋を蓋受容部に挿入する際に、当初は、蓋の外周面から距離を置いて該外周面の周囲に位置している爪端が、蓋受容部に挿入されつつある蓋からの反力によって、蓋の外周面に接触するまで移動させる手段を備えている。これに対して、特許文献１の特開２００３−１３７３９３号公報の明細書の段落「００１３」には、「上記蓋開閉補助具１を、まず容器の蓋８に覆い被せるように合わせる。そして、蓋８を開く方向、即ち図１において把持基台４を固定しながら反時計方向に握り部２を回動すると、上記挟持材５が押圧棒６に押され、該挟持材５は支軸７を中心として図１中矢印で示す方向に回動し、容器の蓋８に当接する。そして、該挟持材５は、容器の蓋８を押圧して、該蓋８を強固に把持することになる。」と記載されており、まず、把持基台を固定しながら握り部を回転させて、挟持材を容器の蓋に当接する必要がある。請求項８に記載の発明は、容器の蓋を蓋受容部に挿入する際に、当初は、蓋の外周面から距離を置いて該外周面の周囲に位置している爪端が、蓋受容部に挿入されつつある蓋からの反力によって、蓋の外周面に接触するまで移動させる手段を備えている。したがって、蓋を蓋受容部に挿入するときに、自動的に爪部材の爪端が蓋の外周面に当接するので、手で可動部材を回転させて爪部材の爪端を容器の外周面に近づけなくても、自動的に近づくので、特許文献１に比べてはるかに扱いに便利である。この結果、蓋を蓋受容部に挿入して、そのまま可動部材を回転させれば上下部材も一緒に回転しながら蓋を開けることができるのである。したがって、請求項７に記載の発明のように、上部材の頂面当接部に上部材よりも摩擦係数の大きな滑り止めを設けることなく、蓋開け具が空回りすることなく確実に蓋を開けることができる。そればかりか、容器の蓋の頂面を上部材の頂面当接部に宛がわなくても蓋を開けることができる。さらには、上部材に頂面当接部がなくても蓋を開けることができる。 The present invention includes an upper member and a lower member that are directly coupled to each other, and a movable member that is movably sandwiched between both members with respect to these members, and a lid receiving portion that allows a lid of a container to be inserted from below. The lower member has an opening of the lid receiving portion, a plurality of claw members are attached between the upper member and the lower member, and each claw member has a rotation axis extending in the vertical direction. When a force is applied to the movable member so as to loosen the lid, the force is transmitted to the claw member and the claw member is rotated, so that the claw end of the claw member is rotated. A claw having a mechanism for press-contacting with the outer peripheral surface of the lid, and initially located around the outer peripheral surface at a distance from the outer peripheral surface of the lid when inserting the lid of the container into the lid receiving portion The end is moved until it comes into contact with the outer peripheral surface of the lid by a reaction force from the lid being inserted into the lid receiving portion. And it includes a stage. On the other hand, in paragraph “0013” of the specification of Japanese Patent Application Laid-Open No. 2003-137393 of Patent Document 1, “the lid opening / closing assisting tool 1 is first fitted so as to cover the lid 8 of the container. When the grip portion 2 is rotated in the direction in which the lid 8 is opened, that is, in the counterclockwise direction while fixing the grip base 4 in FIG. 1, the holding material 5 is pushed by the pressing rod 6, and the holding material 5 is supported by the support shaft 7. 1 is rotated in the direction indicated by the arrow in Fig. 1 and comes into contact with the container lid 8. The clamping member 5 presses the container lid 8 to firmly hold the lid 8. First, it is necessary to rotate the gripping portion while fixing the gripping base to bring the sandwiching material into contact with the lid of the container. According to the eighth aspect of the present invention, when the lid of the container is inserted into the lid receiving portion, initially, the nail ends positioned around the outer peripheral surface at a distance from the outer peripheral surface of the lid are Means for moving until the outer peripheral surface of the lid comes into contact with the reaction force from the lid being inserted into the part. Therefore, when the lid is inserted into the lid receiving portion, the claw end of the claw member automatically comes into contact with the outer peripheral surface of the lid, so that the movable member is rotated by hand so that the claw end of the claw member is brought into contact with the outer peripheral surface of the container. Even if it is not close, it automatically approaches, so it is much more convenient to handle than Patent Document 1. As a result, if the lid is inserted into the lid receiving part and the movable member is rotated as it is, the lid can be opened while the upper and lower members are rotated together. Therefore, as in the seventh aspect of the invention, the lid opening device can be reliably opened without idling without providing a slip stopper having a friction coefficient larger than that of the upper member at the top surface contact portion of the upper member. Can do. In addition, the lid can be opened even if the top surface of the lid of the container is not directed to the top surface contact portion of the upper member. Furthermore, the lid can be opened even if the top member has no top surface contact portion.

さらに、爪端が、蓋受容部に挿入されつつある蓋からの反力によって、蓋の外周面に接触するまで移動させる手段を備えており、その手段は、爪部材に形成された突出部であって、その突出部は、爪部材の回転軸線から爪端に引いた直線方向と異なる方向へ突出するように形成され、突出部は、蓋受容部に挿入された蓋の方向を向く外周面を有し、その外周面は、突出部がその下面から上面に行くに従って徐々に外周面の外周を広げるように、突出部の下面から上面に行くに従って徐々に外側に広がる傾斜面に形成されている。したがって、蓋開け具の使用前に、爪部材の爪端は蓋受容部内に突出させず引っ込めておき、爪部材の突出部を蓋受容部内に突出させておくと、蓋を開ける場合に、蓋を蓋受容部に挿入したときに、蓋の頂面の縁は、最初に突出部の外周面に当たる。ここで、外周面は、突出部の下面から上面に行くに従って徐々に外側に広がる傾斜面に形成されているから、さらに蓋開け具を蓋に押し付けると、外周面に当たった蓋の頂面の縁が外周面上を滑りながら、各突出部を外側に押し広げるので爪部材が回転する。そして、これに対応して、引っ込んでいた爪端が蓋の外周面に近づくように移動し、蓋の外周面に押し当たる。この状態から上部材と下部材と可動部材を同時に回転させれば、すでに、爪端は蓋の外周面に押し当たっているので、蓋開け具は空回りすることなく、その爪端が蓋の外周面に確実に圧接して蓋を回転させることができる。 Furthermore , the claw end is provided with means for moving until it comes into contact with the outer peripheral surface of the lid by the reaction force from the lid being inserted into the lid receiving portion, and the means is a protrusion formed on the claw member. The protruding portion is formed to protrude in a direction different from the linear direction drawn from the rotation axis of the claw member to the end of the claw, and the protruding portion is an outer peripheral surface facing the direction of the lid inserted in the lid receiving portion. The outer peripheral surface is formed in an inclined surface that gradually spreads outward as it goes from the lower surface of the protrusion to the upper surface, so that the outer periphery of the protrusion gradually expands from the lower surface to the upper surface. Yes. Therefore, before using the lid opening tool, the claw end of the claw member is retracted without protruding into the lid receiving portion, and the protruding portion of the claw member is protruded into the lid receiving portion. When inserted into the lid receiving portion, the edge of the top surface of the lid first hits the outer peripheral surface of the protrusion. Here, since the outer peripheral surface is formed as an inclined surface that gradually spreads outward as it goes from the lower surface to the upper surface of the protrusion, when the lid opening tool is further pressed against the lid, the edge of the top surface of the lid that hits the outer peripheral surface While pushing on the outer peripheral surface, the projections are spread outward so that the claw member rotates. Corresponding to this, the nail end that has been retracted moves so as to approach the outer peripheral surface of the lid and presses against the outer peripheral surface of the lid. If the upper member, the lower member, and the movable member are simultaneously rotated from this state, the claw end is already pressed against the outer peripheral surface of the lid, so that the lid opening tool does not rotate freely and the claw end is It is possible to rotate the lid while pressing it securely.

蓋開け具１は、上部材２と下部材３との間に、可動部材４を回転可能に挟持させた構成である。上部材２と下部材３は、図９に示すように３つの結合ネジ５，５，５により直接的に結合されている。 The lid opening tool 1 has a configuration in which a movable member 4 is rotatably held between an upper member 2 and a lower member 3. The upper member 2 and the lower member 3 are directly coupled by three coupling screws 5, 5, 5 as shown in FIG.

図８に示すように、上部材２は、円形をなし、その上面部６の表面が凸面状に形成されている。これは、蓋を開けるときに、上面部６の表面に宛がった手の平をフィットさせるためである。図５に示すように、上部材２の内部には環状壁７が形成され、その環状壁７によって蓋を挿入させるための蓋受容部８が形成される。蓋受容部８の内部中央に凹部９が形成され、その凹部９付近から３つの突条１０，１０，１０が放射状に環状壁７まで延びている。これらの突条１０，１０，１０が、蓋受容部８に挿入された蓋の頂面を当接させる頂面当接部１５，１５，１５を構成する。頂面当接部を一平面に形成してもよいが、３つの突条１０，１０，１０により構成される複数の頂面当接部１５，１５，１５とした理由は、次の通りである。すなわち、仮に頂面当接部１５を平面状に形成すると、蓋の頂面に上部材２の頂面当接部を宛がって蓋を開く方向に回転させようとしたときに、平面状の頂面当接部と蓋の平面状の頂面との接触では滑り易いので、可動部材４と上部材２とが最初から同じ角速度で一緒に回転してしまう虞がある。その場合、図３から明らかな通り、爪部材１３，１３，１３が上部材２，３に対して相対的に回転しないから、各爪部材１３の爪端１４が蓋の外周面に圧接せず、蓋開け具１が空回りするのである。したがって、蓋開け具１の空回りを防止するためには、容器の蓋を開けるときに、まず、上部材２が回転する前に一瞬でも早く可動部材４を回転させることが必要である。そこで、頂面当接部１５，１５，１５を３つの突条１０，１０，１０で形成することによって、蓋開け具１を回転させたときに、各突条１０が蓋の頂面に引っ掛かるように作用し、上部材２が回転を始める前に、可動部材４が先に回転を開始し、それにより各爪部材１３を回転させ、爪端１４を蓋の外周面に圧接させることにより蓋を開けることができるのである。突条１０に代えて、エラストマー樹脂のように柔軟性を有し摩擦力の大きな滑り止めを、上部材２の前記凹部９に嵌め込んで固定したり、接着剤で接着したりしてもよい。 As shown in FIG. 8, the upper member 2 has a circular shape, and the surface of the upper surface portion 6 is formed in a convex shape. This is for fitting the palm addressed to the surface of the upper surface portion 6 when the lid is opened. As shown in FIG. 5, an annular wall 7 is formed inside the upper member 2, and a lid receiving portion 8 for inserting a lid is formed by the annular wall 7. A concave portion 9 is formed in the center of the inside of the lid receiving portion 8, and three protrusions 10, 10, 10 extend radially to the annular wall 7 from the vicinity of the concave portion 9. These ridges 10, 10, 10 constitute top surface abutting portions 15, 15, 15 that abut the top surface of the lid inserted into the lid receiving portion 8. Although the top surface abutting portion may be formed on a single plane, the reason why the plurality of top surface abutting portions 15, 15, 15 constituted by the three protrusions 10, 10, 10 is as follows is there. That is, if the top surface contact portion 15 is formed in a flat shape, the top surface contact portion of the upper member 2 is placed on the top surface of the lid, and the top surface contact portion 15 is flat when attempting to rotate in the direction of opening the lid. Since the contact between the top surface abutting portion and the flat top surface of the lid is slippery, the movable member 4 and the upper member 2 may rotate together at the same angular velocity from the beginning. In this case, as apparent from FIG. 3, the claw members 13, 13, 13 do not rotate relative to the upper members 2, 3, so that the claw end 14 of each claw member 13 does not press against the outer peripheral surface of the lid. The lid opening tool 1 is idle. Therefore, in order to prevent the lid opening tool 1 from spinning freely, it is necessary to first rotate the movable member 4 as soon as possible before the upper member 2 rotates when the lid of the container is opened. Therefore, by forming the top surface abutting portions 15, 15, 15 with the three ridges 10, 10, 10, each ridge 10 is caught on the top surface of the lid when the lid opening tool 1 is rotated. Before the upper member 2 starts rotating, the movable member 4 starts rotating first, thereby rotating each claw member 13 and pressing the claw end 14 against the outer peripheral surface of the lid. It can be opened. Instead of the ridges 10, a non-slip material having flexibility and a large frictional force, such as an elastomer resin, may be fitted into the concave portion 9 of the upper member 2 and fixed, or may be adhered with an adhesive. .

図５に示すように、上部材２の環状壁７の周囲には、３つのネジ孔１６，１６，１６が形成されている。それぞれのネジ孔１６に結合ネジ５をねじ込むことにより、後述するように上部材２と下部材３が直接的に結合される。また、環状壁７の周囲には、上部材２の周方向に延びる３つの弧状ガイド溝１７，１７，１７が形成されている。これらのガイド溝１７は、後述するように、可動部材４の上部材２に対する回転をガイドし、回転を一定の範囲内に限定するためのものである。さらに、環状壁７の周囲には、３つの軸受２１，２１，２１が形成されている。これらの軸受２１は、後述するように、爪部材１３を回転可能に支承するためのものである。 As shown in FIG. 5, three screw holes 16, 16, 16 are formed around the annular wall 7 of the upper member 2. By screwing the coupling screw 5 into each screw hole 16, the upper member 2 and the lower member 3 are directly coupled as described later. Further, around the annular wall 7, three arc-shaped guide grooves 17, 17, 17 extending in the circumferential direction of the upper member 2 are formed. As will be described later, these guide grooves 17 guide the rotation of the movable member 4 relative to the upper member 2 and limit the rotation within a certain range. Further, around the annular wall 7, three bearings 21, 21, 21 are formed. These bearings 21 are for rotatably supporting the claw member 13 as will be described later.

図６に示すように、下部材３は、上部材２と同じ大きさの円形に形成され、中央に開口部１８が形成されている。この開口部１８が、蓋受容部８の入口となる開口部である。開口部１８の周囲に、円筒状に突出する３つのネジ孔部２０，２０，２０が形成され、それぞれネジ孔２４，２４，２４を有する。各ネジ孔部２０が突出している理由は、各ネジ孔部２０の端部が、上部材２の各ネジ孔１６の周囲に形成された各受け溝１９に嵌入することにより、上部材２と下部材３の間隔を一定に保つためである。前述したように、上部材２の環状壁７の周囲には、３つのネジ孔１６，１６，１６が形成されている。そこで、上部材２のネジ孔１６と下部材３のネジ孔２４の位置を合せて上部材２と下部材３を対向させ、そこに結合ネジ５をねじ込むことにより、上部材２と下部材３が直接的に結合される。なお、図２に示すように、結合ネジ５をねじ込んだだけでは、そのネジ頭１１が露出するので、図１に示すように、磁石板１２，１２，１２を取り付けて、ネジ頭１１を覆うことが好ましい。また、磁石板１２を取り付けることにより、蓋開け具１を冷蔵庫の扉などに吸着させておくことができる。 As shown in FIG. 6, the lower member 3 is formed in a circular shape having the same size as the upper member 2, and an opening 18 is formed in the center. This opening 18 is an opening serving as an inlet of the lid receiving portion 8. Three screw hole portions 20, 20, 20 projecting in a cylindrical shape are formed around the opening 18, and have screw holes 24, 24, 24, respectively. The reason why each screw hole 20 protrudes is that the end of each screw hole 20 is fitted into each receiving groove 19 formed around each screw hole 16 of the upper member 2, thereby This is to keep the interval between the lower members 3 constant. As described above, the three screw holes 16, 16, 16 are formed around the annular wall 7 of the upper member 2. Therefore, the upper member 2 and the lower member 3 are aligned by aligning the positions of the screw holes 16 of the upper member 2 and the screw holes 24 of the lower member 3 so that the upper member 2 and the lower member 3 face each other, and screwing the coupling screw 5 there. Are directly coupled. As shown in FIG. 2, the screw head 11 is exposed only by screwing the coupling screw 5, so that the magnet plates 12, 12, 12 are attached to cover the screw head 11 as shown in FIG. It is preferable. Moreover, the lid opening tool 1 can be made to adsorb | suck to the door of a refrigerator, etc. by attaching the magnet plate 12. FIG.

下部材３の開口部１８の周囲には、上部材２の３つのガイド溝１７，１７，１７と対をなすように形成された３つの弧状ガイド溝２２，２２，２２が形成されている。これらのガイド溝２２は、上部材２のガイド溝１７と協働して、可動部材４の回転をガイドし、回転を一定の範囲内に限定する。さらに、開口部１８の周囲には、上部材２の３つの軸受２１，２１，２１と対をなすように形成された軸受２３，２３，２３が形成されている。これらの軸受２３は、上部材の軸受２１と協働して爪部材１３を回転可能に上下両側で支承する。爪部材１３の爪端１４を蓋の外周面に圧接させるためには、爪部材１３を回転させることが必要であるが、爪部材１３が上下両側で支承されているので、爪部材１３は無駄な動きをすることがなく円滑な回転を得ることができる。 Around the opening 18 of the lower member 3, three arc-shaped guide grooves 22, 22, 22 formed so as to make a pair with the three guide grooves 17, 17, 17 of the upper member 2 are formed. These guide grooves 22 cooperate with the guide grooves 17 of the upper member 2 to guide the rotation of the movable member 4 and limit the rotation within a certain range. Further, around the opening 18, bearings 23, 23, 23 are formed so as to be paired with the three bearings 21, 21, 21 of the upper member 2. These bearings 23 support the claw member 13 on both the upper and lower sides in a rotatable manner in cooperation with the bearing 21 of the upper member. In order to press the claw end 14 of the claw member 13 against the outer peripheral surface of the lid, it is necessary to rotate the claw member 13, but since the claw member 13 is supported on both the upper and lower sides, the claw member 13 is useless. Smooth rotation can be obtained without a smooth movement.

図７に示すように、可動部材４は、その外周面３０が、交互に並ぶ６つの凸部３１及び凹部３２により波状をなしている。指を凹部３２にフィットさせることにより、可動部材４を回転させるときに指が滑ることがない。また、可動部材４の内周縁３３の大きさは、図５に示す上部材２の内周縁３５及び図６に示す下部材３の内周縁３６と等しい。また、可動部材４の内周面３４の３カ所に内歯車状歯部３７，３７，３７が形成され、内周面３４に沿って周方向に並ぶ内歯車状歯部３７，３７，３７の間の各区間に、垂直に突出する３つの突起３８，３８，３８がそれぞれ形成されている。これら３つの突起は、可動部材４の下側面にも対称的に形成されている（図示せず。）。突起３８，３８，３８は、可動部材４自体の回転をガイドさせ、回転を一定の範囲内に限定させるためのものである。前述したように、上部材２の環状壁７の周囲には、上部材２の周方向に延びる３つのガイド溝１７，１７，１７が形成されている。同じく、下部材３の開口部１８の周囲には、上部材２の３つのガイド溝１７，１７，１７と対をなすように形成された３つのガイド溝２２，２２，２２が形成されている。上部材２と下部材３が、可動部材４を挟持した状態で結合されたときに、上側のガイド溝１７，１７，１７と下側のガイド溝２２，２２，２２とが対向し、それら対向するガイド溝１７とガイド溝２２とに可動部材の突起３８が係合する。これにより、可動部材４の突起３８がガイド溝１７とガイド溝２２に沿ってスライドしながら、可動部材４は回転する。このように、可動部材４は、回転可能に上部材２と下部材３との間に挟持される。 As shown in FIG. 7, the outer peripheral surface 30 of the movable member 4 is wavy with six convex portions 31 and concave portions 32 that are alternately arranged. By fitting the finger into the recess 32, the finger does not slip when the movable member 4 is rotated. The size of the inner peripheral edge 33 of the movable member 4 is equal to the inner peripheral edge 35 of the upper member 2 shown in FIG. 5 and the inner peripheral edge 36 of the lower member 3 shown in FIG. Further, internal gear-like tooth portions 37, 37, 37 are formed at three locations on the inner peripheral surface 34 of the movable member 4, and the internal gear-like tooth portions 37, 37, 37 aligned in the circumferential direction along the inner peripheral surface 34. Three projections 38, 38, 38 projecting vertically are formed in the respective sections therebetween. These three protrusions are also formed symmetrically on the lower surface of the movable member 4 (not shown). The protrusions 38, 38, 38 are for guiding the rotation of the movable member 4 itself and limiting the rotation within a certain range. As described above, the three guide grooves 17, 17, 17 extending in the circumferential direction of the upper member 2 are formed around the annular wall 7 of the upper member 2. Similarly, around the opening 18 of the lower member 3, three guide grooves 22, 22, 22 formed so as to be paired with the three guide grooves 17, 17, 17 of the upper member 2 are formed. . When the upper member 2 and the lower member 3 are joined together with the movable member 4 sandwiched therebetween, the upper guide grooves 17, 17, 17 and the lower guide grooves 22, 22, 22 are opposed to each other. The protrusion 38 of the movable member is engaged with the guide groove 17 and the guide groove 22 to be engaged. As a result, the movable member 4 rotates while the projection 38 of the movable member 4 slides along the guide groove 17 and the guide groove 22. Thus, the movable member 4 is sandwiched between the upper member 2 and the lower member 3 so as to be rotatable.

図１０に示すように、爪部材１３は、肉厚に形成されており、その周囲の一方の側に外歯車状歯部２６が形成されている。また、他方の側に、爪端１４と突出部２７が形成されている。爪部材１３の上面２８に支軸２５が形成され、図１１に示すように、爪部材１３の下面にも同じように支軸２９が形成されている。爪部材１３は、上部材２、下部材３、可動部材４と共にプラスチックで形成されているが、他の材料、例えば金属などでもよい。なお、爪部材１３には、外歯車状歯部２６が形成されており、可動部材４には、内歯車状歯部３７が形成されていて互いが噛み合って回転するので、これらの部材にはエンジニアリングプラスチックなどの強度や耐摩耗性に優れた材料を使用することが好ましい。 As shown in FIG. 10, the claw member 13 is formed thick, and an external gear tooth portion 26 is formed on one side around the claw member 13. Moreover, the nail | claw end 14 and the protrusion part 27 are formed in the other side. A support shaft 25 is formed on the upper surface 28 of the claw member 13, and a support shaft 29 is similarly formed on the lower surface of the claw member 13 as shown in FIG. 11. The claw member 13 is formed of plastic together with the upper member 2, the lower member 3, and the movable member 4, but may be other materials such as metal. The claw member 13 is formed with an external gear-like tooth portion 26, and the movable member 4 is formed with an internal gear-like tooth portion 37 and meshes with each other. It is preferable to use a material excellent in strength and wear resistance such as engineering plastic.

前述したように、上部材２の環状壁７の周囲には、３つ軸受２１，２１，２１が形成され、下部材３の開口部１８の周囲には、上部材２の軸受２１，２１，２１と対をなすように形成された軸受２３，２３，２３が形成されている。爪部材１３は、その上側の支軸２５を上部材２の軸受２１に係合させ、下側の支軸２９を下部材３の軸受２３に係合させ、外歯車状歯部２６と、可動部材４の内歯車状歯部３７を噛み合わせて、上部材２と下部材３の間に上下両側から支持されて挟持される。これにより、爪部材１３は、支軸２５，２９を中心に回転可能である。図９は、爪部材１３の外歯車状歯部２６と可動部材４の内歯車状歯部３７の噛み合わせ状態を示す図であるが、ここで明らかなように、爪部材１３を回転させるためには、下部材３に対して相対的に可動部材４を回転させる。そうすると、可動部材４と共に内歯車状歯部３７が回転し、この内歯車状歯部３７と噛み合っている爪部材１３の外歯車状歯部２６により、可動部材４の回転が爪部材１３に伝えられて、爪部材１３は回転する。このとき、常に内歯車状歯部３７と外歯車状歯部２６とは噛み合っていることが好ましい。そうでないと、可動部材４の回転が爪部材１３に即座に伝わらないからである。また、仮に、可動部材４が下部材３に対して制限なく回転可能であると、内歯車状歯部３７と外歯車状歯部２６とが噛み合わない状態が生じる。この状態では、容器の蓋を開けることができないので、可動部材４の回転範囲は、内歯車状歯部３７と外歯車状歯部２６とが噛み合っている範囲内にあることが好ましい。このために、前述したように、下部材３の開口部１８の周囲に、上部材２の３つのガイド溝１７，１７，１７と対をなすように３つのガイド溝２２，２２，２２が形成されている。すなわち、上部材２と下部材３が、可動部材４を挟持した状態で結合されたときに、上側のガイド溝１７，１７，１７と下側のガイド溝２２，２２，２２とが対向し、それら対向するガイド溝１７とガイド溝２２とに可動部材４の上下の突起３８（一方は図示せず。）が係合する。この係合により、可動部材４は３６０°自由に回転することのないようにして、可動部材４の回転を、内歯車状歯部３７と外歯車状歯部２６とが噛み合っている範囲内に限定しているのである。可動部材４の回転可能範囲は、好ましくは６０°以下で、最も好ましいのは４０°以下である。 As described above, the three bearings 21, 21, 21 are formed around the annular wall 7 of the upper member 2, and the bearings 21, 21, 21 of the upper member 2 are formed around the opening 18 of the lower member 3. Bearings 23, 23, 23 formed so as to be paired with 21 are formed. The claw member 13 has its upper support shaft 25 engaged with the bearing 21 of the upper member 2 and its lower support shaft 29 engaged with the bearing 23 of the lower member 3, and is movable with the external gear-like tooth portion 26. The internal gear teeth 37 of the member 4 are engaged with each other, and are supported and sandwiched between the upper member 2 and the lower member 3 from above and below. Thereby, the claw member 13 can rotate around the support shafts 25 and 29. FIG. 9 is a view showing a state in which the external gear-like tooth portion 26 of the claw member 13 and the internal gear-like tooth portion 37 of the movable member 4 are engaged with each other. As apparent from FIG. 9, the claw member 13 is rotated. First, the movable member 4 is rotated relative to the lower member 3. Then, the internal gear-like tooth portion 37 rotates together with the movable member 4, and the rotation of the movable member 4 is transmitted to the claw member 13 by the external gear-like tooth portion 26 of the claw member 13 meshing with the internal gear-like tooth portion 37. As a result, the claw member 13 rotates. At this time, it is preferable that the internal gear-like tooth portion 37 and the external gear-like tooth portion 26 are always meshed with each other. Otherwise, the rotation of the movable member 4 is not immediately transmitted to the claw member 13. Further, if the movable member 4 can rotate without limitation with respect to the lower member 3, a state in which the internal gear-like tooth portion 37 and the external gear-like tooth portion 26 do not mesh with each other occurs. In this state, since the lid of the container cannot be opened, the rotation range of the movable member 4 is preferably within a range in which the internal gear-like tooth portion 37 and the external gear-like tooth portion 26 are engaged with each other. Therefore, as described above, the three guide grooves 22, 22, 22 are formed around the opening 18 of the lower member 3 so as to be paired with the three guide grooves 17, 17, 17 of the upper member 2. Has been. That is, when the upper member 2 and the lower member 3 are joined together with the movable member 4 sandwiched therebetween, the upper guide grooves 17, 17, 17 and the lower guide grooves 22, 22, 22 face each other, The upper and lower protrusions 38 (one not shown) of the movable member 4 engage with the guide groove 17 and the guide groove 22 that face each other. By this engagement, the movable member 4 is not freely rotated 360 °, and the rotation of the movable member 4 is within the range where the internal gear-like tooth portion 37 and the external gear-like tooth portion 26 are meshed with each other. It is limited. The rotatable range of the movable member 4 is preferably 60 ° or less, and most preferably 40 ° or less.

図１０から明らかなように、爪部材１３の外歯車状歯部２６は爪部材１３の周囲の一部に形成され、その歯４２の数は４であるが、仮に、この歯４２を爪部材１３の全周に設けたとすると、その歯の数はせいぜい１０である。これに対して、図７に示すように、可動部材４の各内歯車状歯部３７が有する歯４３の数は５であるが、仮に、この歯４３を可動部材４の内周面３３の全周に設けたとすれば、その数は４０以上になることは図７を見れば明らかである。そうすると、可動部材４を回転させたときに、その回転に従って回転する爪部材１３の回転角度は、両歯部のギア比により可動部材４の回転角度の少なくとも４倍の角度になる。したがって、容器の蓋を開けるときに、可動部材４を上下部材２，３に対してわずかに回転させるだけで、爪部材１３はその４倍以上の大きな角度の回転となり、引っ込んでいた爪端１４は即座に蓋の外周面を圧接するので、蓋開け具１が空回りすることを有効に防止することができる。 As apparent from FIG. 10, the external gear-like tooth portion 26 of the claw member 13 is formed at a part of the periphery of the claw member 13 and the number of teeth 42 is four. If it is provided on the entire circumference of 13, the number of teeth is 10 at most. On the other hand, as shown in FIG. 7, the number of teeth 43 included in each internal gear-like tooth portion 37 of the movable member 4 is five. It is clear from FIG. 7 that the number is 40 or more if it is provided all around. Then, when the movable member 4 is rotated, the rotation angle of the claw member 13 that rotates according to the rotation is at least four times the rotation angle of the movable member 4 due to the gear ratio of both tooth portions. Therefore, when the container lid is opened, the movable member 4 is rotated only slightly with respect to the upper and lower members 2 and 3 so that the claw member 13 is rotated at a large angle more than four times that of the claw end 14 that has been retracted. Immediately presses the outer peripheral surface of the lid, so that it is possible to effectively prevent the lid opening tool 1 from spinning around.

前述したように、爪部材１３には突出部２７が形成されている。この突出部２７は、爪部材１３の回転軸線から爪端１４に引いた直線方向と異なる方向へ突出するように形成されている。突出方向は、図１０に示すように回転軸線から爪端１４に引いた直線方向と反対方向であることが好ましい。突出部２７は外周面３９を有し、突出部２７がその下面４０から上面４１に行くに従って徐々に外周面３９の外周を広げて大きくなるように、外周面３９は、突出部２７の下面４０から上面４１に行くに従って徐々に広がる傾斜面に形成されている。この突出部２7の上方に行くに従って広がる外周面３９は、以下に述べるように蓋開け時に優れた効果を発揮する。 As described above, the protrusion 27 is formed on the claw member 13. The protrusion 27 is formed so as to protrude in a direction different from the linear direction drawn from the rotation axis of the claw member 13 to the claw end 14. The protruding direction is preferably opposite to the linear direction drawn from the rotation axis to the claw end 14 as shown in FIG. The protrusion 27 has an outer peripheral surface 39, and the outer peripheral surface 39 is enlarged so that the outer periphery 39 gradually widens and increases as the protrusion 27 extends from the lower surface 40 to the upper surface 41. It forms in the inclined surface which spreads gradually as it goes to the upper surface 41 from. The outer peripheral surface 39 that expands as it goes above the projecting portion 27 exhibits an excellent effect when the lid is opened as described below.

図９に示すように、蓋開け具１の使用前には、爪部材１３の爪端１４は下部材３の開口部１８から蓋受容部８内に突出せず、突出部２７が突出している。蓋を開ける場合に、蓋を蓋受容部１８に挿入したときに、蓋の頂面の縁は、最初に突出部２７の外周面３９に当たる。ここで、外周面３９は、下面から上面に行くに従って徐々に外側に広がる傾斜面に形成されているから、蓋開け具１をさらに蓋の頂面に押し付けると、外周面３９に当たっている蓋の頂面の縁が、外周面３９上を滑りながら上昇し、各突出部２７を外側に押し広げる。そして、これに対応して、爪部材１３が回転し、引っ込んでいた爪端１４が蓋受容部８の方向に移動し、蓋の外周面に押し当たる。この時点で、蓋開け具１を手の平全体でしっかり掴んで蓋開け具１を回転させれば、すでに、爪端１４は蓋の外周面に押し当たっているので、蓋開け具１は空回りすることなく、爪端１４が蓋の外周面に確実に圧接して蓋を回転させることができる。なお、このような効果を確実に発揮させるためには、爪部材１３の肉厚を厚めに形成することが好ましい。爪部材１３の肉厚が薄いと、容器の蓋による突出部２７の外側への押し広げが不十分になり、蓋開け具が空回りする虞があるからである。 As shown in FIG. 9, before using the lid opening tool 1, the claw end 14 of the claw member 13 does not protrude from the opening 18 of the lower member 3 into the lid receiving portion 8, and the protruding portion 27 protrudes. When the lid is opened, when the lid is inserted into the lid receiving portion 18, the edge of the top surface of the lid first hits the outer peripheral surface 39 of the protruding portion 27. Here, since the outer peripheral surface 39 is formed as an inclined surface that gradually spreads outward from the lower surface to the upper surface, when the lid opening tool 1 is further pressed against the top surface of the lid, the top surface of the lid that contacts the outer peripheral surface 39 The edges rise while sliding on the outer peripheral surface 39, and push each protrusion 27 outward. Corresponding to this, the claw member 13 rotates, and the claw end 14 that has been retracted moves in the direction of the lid receiving portion 8 and presses against the outer peripheral surface of the lid. At this time, if the lid opening tool 1 is firmly grasped by the entire palm and the lid opening tool 1 is rotated, the claw end 14 is already pressed against the outer peripheral surface of the lid, so that the lid opening tool 1 does not rotate freely, The end 14 can be reliably pressed against the outer peripheral surface of the lid to rotate the lid. In addition, in order to exhibit such an effect reliably, it is preferable to form the nail | claw member 13 thickly. This is because if the thickness of the claw member 13 is thin, the protrusion of the protrusion 27 to the outside by the lid of the container becomes insufficient, and the lid opening tool may be idle.

上部材２と下部材３の間に挟持された爪部材１３の動きを円滑にして、爪部材１３の爪端１４を容器の蓋に迅速に圧接させ、蓋を確実に回転させ取り外すことができる。 The movement of the claw member 13 sandwiched between the upper member 2 and the lower member 3 can be made smooth, the claw end 14 of the claw member 13 can be quickly pressed against the lid of the container, and the lid can be reliably rotated and removed. .
