A lid opening / closing tool comprising a container body side lid opening / closing tool for fixing the container body with the lid opening / closing tool and a lid side lid opening / closing tool for rotating the lid.

図１、図２、図３、図４は、第一の実施例の蓋開閉具１０であり、容器本体側蓋開閉具２０と蓋側蓋開閉具３０とで構成され、どちらもシリコンゴムなどの柔軟で弾力性のあるゴムやプラスチックで形成されている。また、摩擦係数の大きい材料を使用するのが望ましい。図１，図２に示すように、容器本体側蓋開閉具２０は、円筒形状または円錐形状の外周壁２２と、外周壁２２の内側に張り渡された内側壁２３とから構成されている。外周壁２２は厚さを大きくして剛性を高くし、内側壁２３は薄いシート状に形成されて剛性が低く伸縮が可能としてある。外周壁２２の中には硬質プラスチックや金属を挿入して剛性を上げても良い。 1, FIG. 2, FIG. 3 and FIG. 4 show a lid opening / closing tool 10 of the first embodiment, which is composed of a container body side lid opening / closing tool 20 and a lid side lid opening / closing tool 30, both of which are made of silicon rubber or the like. Made of flexible and elastic rubber or plastic. It is also desirable to use a material with a large coefficient of friction. As shown in FIGS. 1 and 2, the container body side lid opening / closing tool 20 includes a cylindrical or conical outer peripheral wall 22 and an inner side wall 23 stretched inside the outer peripheral wall 22. The outer peripheral wall 22 is increased in thickness to increase rigidity, and the inner wall 23 is formed in a thin sheet shape so that the rigidity is low and can be expanded and contracted. Rigid plastic or metal may be inserted into the outer peripheral wall 22 to increase the rigidity.

容器本体側蓋開閉具２０の外周壁２２の上端と下端は、互いに略平行な面内に形成されている。また、外周壁２２と内側壁２３の間には空洞部２８が形成されている。
図３，図４に示す蓋側蓋開閉具３０は、円錐形状の外周壁３２と内側壁３３とから構成されている。空洞部２８は必須ではないが他の構成は容器本体側蓋開閉具２０と類似である。 The upper end and the lower end of the outer peripheral wall 22 of the container body side lid opening / closing tool 20 are formed in planes substantially parallel to each other. A cavity 28 is formed between the outer peripheral wall 22 and the inner wall 23.
The lid-side lid opening / closing tool 30 shown in FIGS. 3 and 4 includes a conical outer peripheral wall 32 and an inner side wall 33. The hollow portion 28 is not essential, but other configurations are similar to those of the container body side lid opening / closing tool 20.

図５により、蓋開閉具１０の使用方法を説明する。容器本体側蓋開閉具２０の上に容器４０を置いて、容器４０の蓋４４の上に蓋側蓋開閉具３０を被せる。そして、手で蓋側蓋開閉具３０を押さえながら回転させ、蓋４４を開閉する。なお、蓋側蓋開閉具４０を使用せず、直接手で蓋４４を回してもよい。 A method of using the lid opening / closing tool 10 will be described with reference to FIG. The container 40 is placed on the container body side lid opening / closing tool 20, and the lid side lid opening / closing tool 30 is put on the lid 44 of the container 40. Then, the lid 44 is rotated while holding the lid side lid opening / closing tool 30 by hand to open and close the lid 44. The lid 44 may be directly turned by hand without using the lid-side lid opening / closing tool 40.

この時の断面図を図６で示し、下部・左側の詳細を図７で示す。このとき、容器本体４２は力Fで下方に押され、内側壁２３を力Fで下方に押し、内側壁２３は図のように変形する。このことにより、内側壁２３が容器本体４２を包み込み容器本体側蓋開閉具２０と容器本体４２との摩擦力はより大きくなる。 A cross-sectional view at this time is shown in FIG. 6, and details of the lower and left sides are shown in FIG. At this time, the container body 42 is pushed downward by the force F, the inner wall 23 is pushed downward by the force F, and the inner wall 23 is deformed as shown in the figure. As a result, the inner wall 23 wraps around the container body 42, and the frictional force between the container body side lid opening / closing tool 20 and the container body 42 becomes larger.

即ち、容器本体４２が下方に押されると外周壁２２と内側壁２３が矢印Wの方向に倒れて、内側壁２３が容器本体４２の側壁を力Gで押圧する。この時の、容器本体４２と内側壁２３との摩擦力Mは次の様になる。
M＝F×μ+G×μ
ここで、μは容器本体４２と内側壁２３との摩擦係数である。
つまり、このような構成とすることにより、G×μだけ摩擦力が増大する効果が得られる。
ここで、内側壁２３とテーブル面に空洞部２８があるので、内側壁２３が下方に下がる余裕が確保してある。 That is, when the container main body 42 is pushed downward, the outer peripheral wall 22 and the inner side wall 23 fall in the direction of the arrow W, and the inner side wall 23 presses the side wall of the container main body 42 with the force G. The frictional force M between the container main body 42 and the inner wall 23 at this time is as follows.
M = F × μ + G × μ
Here, μ is a coefficient of friction between the container body 42 and the inner wall 23.
That is, with such a configuration, an effect of increasing the frictional force by G × μ can be obtained.
Here, since the inner wall 23 and the table surface have the cavity 28, a margin for the inner wall 23 to be lowered is secured.

さらに、図８により平面図で見た状況を説明する。容器本体４２がLの方向に回転すると、外周壁２２は拘束されているので内側壁２３は捻られて引き線２６方向に引かれて、内側壁２３が容器本体４２に巻き付く。このことにより、内側壁２３が容器本体４２を締め付ける力Gが増大する。その結果、M1＝G×μが大きくなり、摩擦抵抗M1がさらに大きくなる。そして、摩擦抵抗M1が大きくなるとGも大きくなる好循環が生まれる。 Further, the situation seen in a plan view will be described with reference to FIG. When the container main body 42 rotates in the direction L, the outer peripheral wall 22 is restrained, so the inner side wall 23 is twisted and pulled in the direction of the drawing line 26, and the inner side wall 23 is wound around the container main body 42. As a result, the force G with which the inner wall 23 clamps the container body 42 increases. As a result, M1 = G × μ is increased, and the frictional resistance M1 is further increased. A virtuous cycle in which G increases as the frictional resistance M1 increases is born.

次に、図７により、容器本体側蓋開閉具２０と、これが置かれたテーブル面との摩擦トルクTを考える。外周壁２２がテーブル面を押す力はFであるので、摩擦トルクTは次の様になる。
T=F×μ１×D３
ここで、D3は外周壁２２の直径、μ１は外周壁２２とテーブル面の摩擦係数である。
即ち、D3をD1やD2より大きくとっているので、外周壁２２とテーブル面が滑り難くくなる効果を得ている。 Next, referring to FIG. 7, the friction torque T between the container body side lid opening / closing tool 20 and the table surface on which it is placed will be considered. Since the force with which the outer peripheral wall 22 presses the table surface is F, the friction torque T is as follows.
T = F × μ1 × D3
Here, D3 is the diameter of the outer peripheral wall 22, and μ1 is the coefficient of friction between the outer peripheral wall 22 and the table surface.
That is, since D3 is larger than D1 and D2, the effect of making it difficult for the outer peripheral wall 22 and the table surface to slip is obtained.

次に、蓋側蓋開閉具３０と蓋４４との摩擦を考察すると、内側壁２３と容器本体４２との関係と同様、内側壁３３が変形して、蓋４４との摩擦力を向上することができる。また、内側壁３３より外周壁３２の外径が大きいので、蓋４４を回転するトルクも大きくすることができる。 Next, considering the friction between the lid-side lid opening / closing tool 30 and the lid 44, the inner wall 33 is deformed and the frictional force with the lid 44 is improved as in the relationship between the inner wall 23 and the container body 42. Can do. Moreover, since the outer diameter of the outer peripheral wall 32 is larger than the inner wall 33, the torque for rotating the lid 44 can also be increased.

図９、図１０は第二の実施例であり、外周壁２２の下方に放射状に凹部２７を設けたものである。外周壁２２をテーブル面とスリップし難くし、材料の節約の効果もある。 FIGS. 9 and 10 show a second embodiment, in which concave portions 27 are provided radially below the outer peripheral wall 22. The outer peripheral wall 22 is less likely to slip with the table surface, and there is an effect of saving material.

図１１は第三の実施例、図１３は第五の実施例であり、蓋側蓋開閉具３０に係合部３５を設けて、非使用時に蓋側蓋開閉具３０を容器本体側蓋開閉具２０の空洞部２８に挿入し係合部２５に係合させ、不用意にバラバラにならないようにしたものである。 FIG. 11 shows a third embodiment, and FIG. 13 shows a fifth embodiment. The lid-side lid opening / closing tool 30 is provided with an engaging portion 35 so that the lid-side lid opening / closing tool 30 can be opened and closed when the container is not in use. It is inserted into the cavity portion 28 of the tool 20 and engaged with the engaging portion 25 so as not to fall apart carelessly.

図１２は第四の実施例であり、内側壁２３として、大きい内側壁２３Aと小さい内側壁２３Bを並べて設けたものである。これにより、大きい容器本体４２と小さい容器本体４２のどちらにもより対応し易くしている。 FIG. 12 shows a fourth embodiment, in which a large inner wall 23A and a small inner wall 23B are provided side by side as the inner wall 23. FIG. This makes it easier to handle both the large container body 42 and the small container body 42.

図１４は第六の実施例であり、内側壁２３の下面に第二の外周壁２９を設けたものである。これにより、蓋開閉具１０のサイズを大きくせず、大きい容器本体４２と小さい容器本体４２のどちらにも対応し易くしている。 FIG. 14 shows a sixth embodiment in which a second outer peripheral wall 29 is provided on the lower surface of the inner wall 23. Thereby, the size of the lid opening / closing tool 10 is not increased, and both the large container main body 42 and the small container main body 42 are easily supported.

以上の実施例の蓋開閉具は、蓋開閉具としてだけでなく、急須などを卓上に置く際の敷物としても、また開口部を上にすれば容器としても利用可能であるので、蓋開閉具として使用しないときでも邪魔にならない。 The lid opening / closing device of the above embodiment can be used not only as a lid opening / closing device, but also as a rug when placing a teapot on a table or as a container with the opening up, It will not get in the way even when not used.

この発明の蓋開閉具は、片手が不自由な人だけでなく、両手が使えるが力の弱い人にも有用である。 The lid opening / closing tool of the present invention is useful not only for a person who has difficulty with one hand, but also for a person who can use both hands but is weak.
