A lid opening / closing tool comprising a cavity between an inner peripheral wall of a fixing tool and an inner peripheral wall of the fixing tool.
The lid opening / closing tool according to the above, characterized in that the lid opening / closing body can be accommodated inside the container body fixing tool.
A lid opening / closing tool for a container lid, and a substantially cylindrical or conical fixing tool outer peripheral wall, and an inverted conical fixing tool formed by inclining inward and downward from the vicinity of the upper end of the fixing tool outer peripheral wall. It is composed of a peripheral wall and a cavity formed between the outer peripheral wall of the fixture and the inner peripheral wall of the fixture, and the lower end and the upper end of the outer peripheral wall of the fixture are each formed in a substantially parallel plane. It is a lid opening / closing tool.

  1 and 2 show a lid opening / closing tool 10 of the first embodiment, which is composed of a container body fixing tool 20 and a lid opening / closing body 30, both of which are flexible and elastic rubber or plastic such as silicone rubber. A material with a high coefficient of friction is desirable. As shown in FIGS. 3 and 4, the container body fixture 20 includes a cylindrical or conical fixture outer peripheral wall 22 and an inverted conical fixture inclined downward and inward from the upper end of the fixture outer peripheral wall 22. The inner peripheral wall 24 and a fixture bottom 26 connected to the lower end of the fixture inner peripheral wall 24 are configured.

The upper end and the lower end of the fixture outer peripheral wall 22 are formed in planes substantially parallel to each other. A cavity 28 is formed between the fixture outer peripheral wall 22 and the fixture inner peripheral wall 24. The lower end of the fixture inner peripheral wall 24 is formed above the lower end of the fixture outer peripheral wall 22 by S.
The lid opening / closing body 30 shown in FIGS. 5 and 6 includes a conical opening / closing body outer peripheral wall 32 and an opening / closing body top 34. The opening / closing body outer peripheral wall 32 is formed so as to be inclined in a substantially inverted conical shape downward from the substantially circular outer end inward. Here, the conical shape and the inverted conical shape mean a shape obtained by cutting out a conical shape or an inverted conical shape.

  As shown in FIGS. 1 and 2, the lid opening / closing body 30 is formed so as to be housed along the inner side of the fixture inner peripheral wall 24 of the container body fixture 20. That is, the inclination and size of the inner side of the inner peripheral wall 24 of the fixing tool 20 are substantially the same or slightly larger than the outer side of the outer peripheral wall 32 of the opening / closing body 30.

  As described above, when the lid opening / closing body 30 is housed in the container body fixing tool 20, the upper end of the container body fixing tool 30 and the upper end of the opening / closing body 30 are configured on substantially the same plane. Therefore, the lid opening / closing tool 10 can be stored in a compact manner, and can also be used as a stand on which a teapot or the like is placed in this state.

  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 fixing tool 20, and the lid opening / closing body 30 is turned upside down on the lid 44 of the container 40. Then, as shown in FIG. 8, the lid 44 is rotated while holding the lid opening / closing body 30 with the hand 50 to open and close the lid 44. FIG. 9 shows a cross-sectional view at this time, and FIG. 10 shows details of the lower and left sides. At this time, the container main body 42 is pushed downward by the force F, the fixture inner peripheral wall 24 is pushed downward by the force F, and the fixture inner peripheral wall 24 is deformed like A. As a result, the inner peripheral wall 24 of the fixture wraps the container body 42 and the frictional force between the container body fixture 20 and the container body 42 increases.

That is, when the container main body 42 is pushed downward, the fixture outer peripheral wall 22 is inclined in the direction of arrow W, and the fixture inner peripheral wall 24 presses the side wall of the container main body 42 with a force G. The frictional force M between the container main body 42 and the fixture inner peripheral wall 24 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 peripheral wall 24 of the fixture.
That is, with such a configuration, an effect of increasing the frictional force by G × μ can be obtained.
Here, since there is a gap S between the lower end of the fixture inner peripheral wall 24 and the table surface, the fixture outer peripheral wall 24 is lowered downward, the fixture outer peripheral wall 24 falls in the W direction, and G is increased.

Next, consider the friction torque T between the container body fixture 20 and the table surface. Since the force with which the fixture outer peripheral wall 22 pushes the table surface is F, the friction torque T is as follows.
T = F × μ1 × D3
Here, D3 is the diameter of the fixture outer peripheral wall 22, and μ1 is the coefficient of friction between the fixture outer peripheral wall 22 and the table surface.
That is, since D3 is larger than D1 and D2, the effect is that the outer peripheral wall 22 of the fixture and the table surface are less likely to slip.

Next, considering the friction between the lid opening / closing body 30 and the lid 44, the opening / closing body outer peripheral wall 32 is deformed and the frictional force can be improved in the same manner as the relationship between the fixture inner peripheral wall 24 and the container main body 42.
Further, if the force for rotating the lid opening / closing body 30 with the hand 50 is H, the rotational torque L is as follows.
L = H × E2
However, E2 is the diameter of the point of application of the force applied by the hand 50 to the lid opening / closing body 30.
That is, since E2 is larger than the diameter E1 when the lid opening / closing tool 10 is not used, the lid 44 can be rotated with a large torque.

  FIG. 11 shows a second embodiment in which an engagement portion 36 is provided on the top 34 of the lid opening / closing body 30 so that the lid opening / closing body 30 is engaged with the container body fixing tool 20 when not in use, It was made so that it would not be.

FIG. 12 shows a third embodiment, in which a filling member 60 is inserted into the recess of the lid opening / closing body 30 to flatten the upper surface of the lid opening / closing tool 10 so that it can be easily used as a pan or a coaster.
FIG. 13 is applied as a cutting board for cutting spherical fruits and vegetables such as apples, and one or a plurality of grooves 21 are provided radially on the upper surface of the lid opening / closing tool 10 to form a knife groove. By detaching the lid opening / closing body 30, it is possible to deal with large and small size vegetables and fruits.
Thus, since the lid opening / closing tool 10 can be used for other purposes even when not in use as the lid opening / closing tool, it can be used by being always placed on a sink or a table.

  FIG. 17 shows a fifth embodiment in which the lid is opened between the lid opening / closing tool 10 and the container 40, between the lid opening / closing tool 10 and the table surface, or between the lid opening / closing tool 10 and the lid 44. Is provided with a unidirectional restraint portion as shown in the figure having a large frictional resistance and a small frictional resistance in the opposite direction.

  The lid opening / closing tool of the present invention can be used not only as a lid opening / closing tool but also as a rug when placing a teapot or the like on a table.
