In the container lid disclosed in Japanese Utility Model Laid-Open Publication No. 55-148064, a quantitative operation is ensured in which an appropriate amount of drainage specified by a single pressing operation is reliably performed, and a good operation that is performed with an appropriate pressing force is performed. It is difficult to simultaneously satisfy (balance) various requirements such as resilience and reliable restorability for quickly restoring the original shape. That is, in the case of the container lid, when the dome-shaped head is excessively soft, the container is inverted when pressed with a fingertip, and cannot be restored to the original shape. On the other hand, if it is obviously soft, if not excessive, the restoration will not be carried out quickly, and the liquid in the drainage cylinder will not be able to return completely, which may cause dripping. Therefore, in order to ensure resilience, the dome-shaped head is formed to be considerably hard. Since the dome-shaped head is hard, the operability is extremely poor, and the degree of depression for quantitative drainage is ambiguous, so that it is difficult to ensure quantitativeness.

That is, as described above, the container lid includes the lid main body and the air supply unit. An air supply having a bellows-like side wall is extremely difficult, if not impossible, to be formed integrally with the lid body. Therefore, the container lid of this embodiment has an increased number of parts and a complicated configuration. In addition, in order to ensure the quantitativeness, a restriction wall portion which is partially removed from the upper end edge thereof so as to be manually operable is formed in a portion of the guide wall portion of the lid body facing the drainage cylinder.
That is, when the air supply unit is pressed with a fingertip, the operator's finger comes into contact with the upper end of the restricting wall to try to limit the amount of pressurization, but in this configuration, the drainage amount is kept constant. Is difficult, especially when a small amount of drainage is required.

The pressing force acts on the inner peripheral edge of the upper annular wall of the elastically deformable portion via the cylindrical wall of the pressed portion. The upper annular wall is deformed with the upper end of the cylindrical wall of the elastic deformation portion (the outer peripheral edge of the upper annular wall) as a fulcrum, and the inner peripheral edge moves downward in the axial direction. The pressing force acts on the inner peripheral edge of the lower annular wall via the cylindrical wall of the elastic deformation portion. The lower annular wall is deformed with its outer peripheral edge as a fulcrum, and its inner peripheral edge moves downward in the axial direction. As described above, the elastic deformation portion gradually deforms from the upper annular wall and the lower annular wall which are relatively weak to the axial force. The cylindrical wall of the elastically deforming portion is also deformed by further pressing of the pressed portion.
When the deformation of the elastically deformable portion substantially reaches the limit, the pressed portion stops moving while sinking into the cylindrical wall of the elastically deformable portion while substantially retaining its shape. The liquid is discharged from the drainage cylinder by the above pushing operation. When the pressing is released, the elastically deformed portion returns to its original shape by the restoring force due to its elasticity, and the pressed portion returns to its original position. As a result, the liquid in the drainage tube portion is drawn back into the container lid.

で、制作は一層容易となる。In the pressing operation, when the deformation of the elastically deformable portion substantially reaches a limit, the pressed portion formed by the cylindrical wall and the circular upper wall substantially retains its shape while holding the inside of the cylindrical wall of the elastically deformable portion. It stops reliably in the form of sinking in. That is, the elastic deformation portion has a lower annular wall, a cylindrical wall extending upward from the inner peripheral edge of the lower annular wall, and an upper annular wall extending radially inward from the upper end of the cylindrical wall. The annular wall, the lower annular wall, and the circular upper wall of the pressed portion each extend substantially horizontally, and the cylindrical wall of the elastically deforming portion and the cylindrical wall of the pressed portion are each configured to extend substantially vertically. The pressing amount of the pressing portion is reliably regulated by the elastic deformation portion itself, and the total deformation amount can be relatively small, so that the pressing amount of the pressed portion can be reduced without providing special stop means. Is maintained approximately constant,
The specified proper amount of drainage, especially a small amount of fixed amount of drainage is ensured. Therefore, the container lid according to the present invention can be suitably used particularly for draining highly viscous contents such as vicious oil one by one every time the pressed portion is pressed. The elastic deformation portion has a lower annular wall, a cylindrical wall extending upward from an inner peripheral edge of the lower annular wall, and an upper annular wall extending radially inward from an upper end of the cylindrical wall. The annular wall and the lower annular wall each extend substantially horizontally, and the cylindrical wall of the elastically deforming portion is configured to extend substantially vertically, so that its resilience is excellent. As a result, the dripping from the drainage cylinder is reliably prevented, so that the container lid according to the present invention can be suitably used particularly for draining highly viscous contents such as sharp oil.
The elastically deforming portion has a lower annular wall, a cylindrical wall extending upward from an inner peripheral edge of the lower annular wall, and an upper annular wall extending radially inward from an upper end of the cylindrical wall. It has a cylindrical wall extending upward from the inner peripheral edge of the upper annular wall of the deformable portion, and a circular upper wall connected to the cylindrical wall, and the upper and lower annular walls of the elastically deformable portion and the circular upper wall of the pressed portion. Extend substantially horizontally, and the cylindrical wall of the elastically deforming portion and the cylindrical wall of the pressed portion extend substantially vertically, respectively, so that the entire container lid is integrally formed by injection molding or compression molding with synthetic resin. It is possible to do. As a result, the production is extremely easy and the number of parts is one, so that the construction is simple and the production can be performed at low cost. During the pressing operation, the pressed portion is maintained in the substantially initial shape, the pressing direction of the pressed portion due to the deformation of the elastic deformation portion is constant, and the elastic deformation portion is relatively weak to the axial force. The operability is extremely good because the pressing operation can be performed with an appropriate pressing force due to the gradual deformation from the annular wall and the lower annular wall. Since the upper annular wall and the lower annular wall of the elastically deformable portion are configured to be thin and flexible, they can be elastically deformed easily enough, and operability is further improved. Furthermore, in the present invention, even if there is a slight production error, securing of quantitativeness, good operability,
Since it does not affect various characteristics such as reliable resilience, production becomes easier.

一層容易となる。The pressing operation of the elastic crushing portion 18 is performed when the deformation of the elastic deformation portion 20 reaches a practical limit.
The pressed portion 22 composed of the zero and the circular upper wall 32 is reliably stopped in a form sinking into the cylindrical wall 26 of the elastically deforming portion 20 while substantially maintaining its shape. That is, the elastic deformation portion 2
0 has a lower annular wall 24, a cylindrical wall 26 extending upward from the inner peripheral edge of the lower annular wall 24, and an upper annular wall 28 extending radially inward from the upper end of the cylindrical wall 26.
0 upper annular wall 28 and lower annular wall 24 and pressed portion 22
Since the circular upper wall 32 extends substantially horizontally, the cylindrical wall 26 of the elastically deformable portion 20 and the cylindrical wall 30 of the pressed portion 22 are each configured to extend substantially vertically. Since the amount is reliably regulated by the elastically deformable portion 20 itself, and the total amount of deformation can be relatively small, it is easy to reduce the amount of pushing of the pressed portion 22 without providing special stop means. It is kept constant and ensures a defined, appropriate drainage, in particular a small amount of constant drainage. Therefore, the container lid 2 according to the present invention
Particularly, the highly viscous contents such as sharp oil are
It can be suitably used to discharge one drop at a time for each press. The elastic deformation portion 20 has a configuration including a lower annular wall 24, a cylindrical wall 26 extending upward from an inner peripheral edge of the lower annular wall 24, and an upper annular wall 28 extending radially inward from an upper end of the cylindrical wall 26. In addition, the upper annular wall 28 and the lower annular wall 24 of the elastically deformable portion 20 extend substantially horizontally, and the cylindrical wall 26 of the elastically deformable portion 20 is substantially vertically extended. As a result, the liquid dripping from the drainage cylinder 8 is reliably prevented, so that the container lid 2 according to the present invention is provided.
Can be suitably used particularly for draining highly viscous contents such as sharp oil. The elastic deformation portion 20 has a lower annular wall 24, a cylindrical wall 26 extending upward from an inner peripheral edge of the lower annular wall 24, and an upper annular wall 28 extending radially inward from an upper end of the cylindrical wall 26, The pressed portion 22 is formed by the elastic deformation portion 20.
Cylindrical wall 30 extending upward from the inner peripheral edge of upper annular wall 28
And a circular upper wall 32 connected to the cylindrical wall 30. The upper annular wall 28 and the lower annular wall 24 of the elastically deformable portion 20 and the circular upper wall 32 of the pressed portion 22 each extend substantially horizontally, Since the cylindrical wall 26 of the elastic deformation portion 20 and the cylindrical wall 30 of the pressed portion 22 are each configured to extend substantially vertically, the entire container lid 2 can be integrally formed by injection molding or compression molding with synthetic resin. It becomes possible. As a result, the production is extremely easy and the number of parts is one, so that the construction is simple and the production can be performed at low cost. During the pressing operation, the pressed portion 22 is maintained in a substantially initial shape, the pressing direction of the pressed portion 22 due to the deformation of the elastic deformation portion 20 is constant, and the elastic deformation portion 20 is subjected to an axial force. Relatively weak upper annular wall 28 and lower annular wall 24
The operability is extremely good because the pressing operation can be performed by an appropriate pressing force by gradually deforming from the beginning. Since the upper annular wall 28 and the lower annular wall 24 of the elastically deforming portion 20 are configured to be thin and flexible, they can be easily and elastically deformed, and the operability is further improved. Further, in the present invention, even if there is some production error, production is further facilitated because it does not affect various characteristics such as securing of quantitativeness, good operability, and reliable restoration.

As a result, as described above, the elastically crushed portion 18 of the container lid 2 elastically returns to the original state, thereby generating some negative pressure in the container body 38 and the container lid 2; In addition, since the drainage tube 8 of the container lid 2 is inclined upward and extends linearly outward in the radial direction, the liquid that has filled the drainage tube 8 at the time of draining an appropriate amount is drained. The liquid flows in the liquid cylinder 8 toward the upstream thereof and flows into the container body 38.

容器本体内に引き戻すことができる。Since the container lid 2 is originally small in volume, it is used for the purpose of draining an appropriate amount (a small amount), and the suction force due to the negative pressure caused by the restoration of the elastically crushed portion 18 is weak. Therefore, after an appropriate amount of liquid is drained, the liquid in the drainage cylinder 8 may not be completely drawn back into the container body 38 due to restoration of the elastic crushing portion 18 and may remain. In the container lid 2, even if there is such a residue, the liquid is sucked at least to the downstream end of the upstream portion 10u (the upstream end of the downstream portion 10d) by the negative pressure caused by the restoration of the elastic crushing portion 18. If this is done (even if the suction force due to the negative pressure is weak, suction to this site is always performed reliably), this residual liquid will have a flow path cross-sectional area Au of the upstream portion 10u (opening 6) of the downstream portion 10d. Is reliably pulled back into the container body 38 by the action of the suction force, which is presumed to be caused by the capillary phenomenon caused by making the flow path cross-sectional area Ad smaller than the above. That is, the suction force due to the negative pressure caused by the restoration of the elastically crushed portion 18 and the capillary phenomenon caused by the passage sectional area Au of the upstream portion 10u (opening 6) being made smaller than the passage sectional area Ad of the downstream portion 10d. The liquid in the drainage cylinder 8 can be reliably drawn back into the container main body even in the container lid 2 having a weak suction force after draining an appropriate amount of liquid by the synergistic action with the suction force estimated to be caused by the above.

Quantitative property is ensured. In addition, since operation can be performed with an appropriate pressing force, good operability is ensured. Further, by releasing the pressing force against the pressed portion, the original shape can be restored at an appropriate timing, so that a quick and reliable restoring property is also achieved. Since the entire container lid can be integrally molded with synthetic resin, the production is extremely easy and the production can be performed at low cost. Even if a slight error occurs in the production, the above effect is not affected, and the production is further facilitated.
