Abstract

PURPOSE:To prevent liquid from leaking by providing a liquid path for discharging liquid from a device on a body, wherein a passage part having a first opening opened at an opening end and a second opening located above the opening end are included so that liquid is guided upward from the opening end at a mouth part. CONSTITUTION:Liquid 2 contained in a vessel body 3 does not flow out of a vessel 1 since pressure inside 5 the vessel body 3 functioning to a liquid level 48 and atmospheric pressure functioning to a liquid level 49 are balanced. When the vessel body 3 is pushed and deformed, pressure inside 6 the vessel body 3 functioning to the liquid level 48 becomes larger than the atmospheric pressure functioning to the liquid level 49 so that the liquid 2 passes through a path 20 over an opening 22 of a path 18 and is poured out from an outlet 24. Then, if pressing the vessel body 3 is released, the body 3 restores to its original shape due to elastic force of the body 3, reducing pressure inside 5 the vessel body 3 functioning to the liquid level 48. This allows a part of the liquid 2 remaining in the path 20 to flow back in a direction opposite to that indicated by an arrow 19 and return to the path 18, where balanced state is restored again to have the liquid level 49 placed at the path 18.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a liquid discharge mechanism.

[Prior Art I] Conventionally, there has been a demand for a device having a liquid discharge mechanism to discharge the liquid reliably with a simple operation.

For example, in a container, there is a demand for pouring out a desired amount of liquid contained in the container without removing the cap of the container.

[Problem to be Solved by the Invention 1] However, in conventional devices that allow liquid to be discharged with a simple operation, liquid leakage is likely to occur. In a container configured to pour out liquid, there is a problem in that when the container is placed in a position other than an upright position, that is, in an upside down position or a sideways position, the liquid gradually leaks out.

The present invention has been made in view of the above-mentioned points, and its object is to provide a liquid discharge mechanism that is unlikely to cause liquid leakage, that is, in the case of a container, to remove the liquid from the container without removing the cap of the container. To provide a container configured such that liquid can be poured out and liquid does not easily leak under any condition.

[Means for Solving the Problems] According to the present invention, the object is to provide a body device configured to accommodate a liquid and to increase/decrease pressure on the liquid, a mouth formed at the lower end of the body device for discharging liquid; a first opening opened at the opening end to guide the liquid upward from the opening end of the mouth; This is achieved by a liquid evacuation mechanism comprising at least a passageway portion of the body having a second opening located above the end, for discharging the liquid from the body device.

[Function] In the liquid discharge mechanism according to the present invention, the pressure on the liquid is increased by the body device, the liquid is poured out through the mouth and the liquid passage, and the pressure is increased by the body device. The system reduces the amount of liquid remaining in the liquid passage and stops pouring out the liquid while causing the liquid remaining in the liquid passage to flow backwards. In this stopped state, the pressing force of the chest device and the pressing force of atmospheric pressure on the liquid are reduced. are balanced, and the liquid becomes difficult to leak from the body device.

Note that the liquid here refers not only to liquids in general, but also to
It also contains something like a gel-like fluid with extremely high viscosity.

[Specific Example] Next, a container that is a preferred specific example of the liquid discharge mechanism according to the present invention will be described based on the drawings.

As shown in FIG. 1, a container 1 having a liquid discharge mechanism according to the present invention includes a container body 3 constituting a body device formed to contain a liquid 2, and a container body 3 for the liquid 2. It is composed of an inlet/outlet part 4 for pouring in and out.

The container body 3 is composed of a bottom part 6 and a side wall part 7, and is entirely made of a flexible elastic material such as plastic. Therefore, by pressing and deforming the container body 3, the pressure inside 5 of the container body 3 increases, and the liquid 2
is poured out from the inlet/outlet section 4. Further, when the suppression of the container body 3 is released, the elastic force of the container body 3 restores the deformed state to the original state, and the pressure inside the container body 3 decreases. The liquid 2 flows backward and is no longer poured out from the inlet/outlet portion 4.

That is, in this specific example, the pressure inside 5 of the container body 3 is adjusted by forming the container body 3 from a flexible elastic material, and the pressure on the liquid 2 is increased or decreased.

Incidentally, instead of forming the entire container body 3 from a flexible elastic material as a means for adjusting the pressure inside the interior 5 as described above, a part of the container body 3, e.g. bottom 6
It may be formed of a flexible elastic material into a diaphragm shape, and the bottom portion 6 may be configured to be movable in the direction indicated by the arrow 8. In the container body 3 configured in this way, by pressing the bottom 6 in the direction shown by the arrow 9 and deforming it into the state shown by the broken line, the pressure inside the container body 3 increases and the liquid 2 is poured out from the entrance/exit part 4, and when the pressure on the bottom part 6 is released, the elastic force of the bottom part 6 restores the deformed state to the original state shown by the solid line, and the inside 5 of the container body part 3 The pressure of liquid 2 decreases and
is returned and is no longer poured out from the inlet/outlet portion 4. Note that instead of forming the bottom portion 6 in the shape of a diaphragm, the side wall portion 7
A part of it may be formed into a diaphragm shape.

Furthermore, as shown in FIG.
and a piston device 10 attached to the container body 3. The piston device 10 includes a piston member 11 configured to be able to slide airtight in the direction shown by an arrow 8 inside the container body 3.
and a rod member 13 connected at one end to the piston member 11 and inserted into a through hole 12 formed in the bottom 6 of the container body 3. In the body device configured in this manner, by pressing the piston device 10 in the direction not shown by the arrow 9, the pressure inside the container body 3 increases and the liquid 2 is poured out from the inlet/outlet portion 4. By further pulling back the piston device 10 in the direction shown by the arrow 14, the pressure inside the container body 3 is reduced, and the liquid 2 is returned to the inside and is no longer poured out from the inlet/outlet portion 4.

Note that a power unit (not shown) that reciprocates in the direction shown by arrow 8 may be connected to the other end of the rod member 13 to control the operation of the piston device 10. In this case, by further connecting a control means (not shown) such as a numerical control device to the power device, the piston device 1
0, that is, the liquid 2 discharge operation can be automatically controlled.

As shown in FIG.
A spout 15 is provided at the lower end of the container body 3 to allow the liquid 2 contained in the container body 3 to enter and exit, and the liquid 2 from the spout 15 is directed to the side opposite to the opening end 16 of the spout 15, that is, upwardly. a passage 18 as a passage part configured to guide in the direction indicated by the arrow 17 towards the bottom 6 of the container body 3 located at;
Arrow 1 opposite to the upward direction of liquid 2 indicated by arrow 17
It has a passage 20 as a passage part configured to guide in the direction indicated by 9, ie downward.

The mouth portion 15 includes a wide mouth portion 25 formed by a wall member 27 and a narrow mouth portion 26 formed by a wall member 28 fitted to the wall member 27. In this specific example, the wall member 27 and the wall member 28 are formed as separate members, but of course they may be formed as one piece.

The passage 18 has an opening 21 that opens at the open end 16 of the narrow portion 26 and an opening 22 that is located closer to the bottom 6 than the open end 16, that is, above the open end 16. That is, passage 18
is constituted by an inner surface 31 of a wall member 30 having a protruding end 29 facing the wall member 28 and forming an opening 22 together with the wall member 28, and an outer surface 32 of the wall member 28. There is. The projecting end 29 is therefore located closer to the bottom 6 than the open end 16 of the narrow part 26, i.e. above, so that the channel 18 can guide the liquid 2 in the direction indicated by the arrow 17.

The wall member 30 has a projecting end 2 as shown in FIGS. 1 and 4.
It is connected to the flange portion 33 at a portion 9. An outflow hole 34 is provided at the protruding end 29 for allowing the liquid 2 to flow out from the opening 22 of the passage 18 toward the opening 23 of the passage 20, which will be described later. In this specific example, the outflow hole 3
4, the shape was formed into an ellipse, and eight holes were provided at equal intervals along the circumference of the protruding end 29, but the number and size of the holes may be changed depending on the characteristics such as the viscosity or specific gravity of the liquid 2 contained in the container 1. , it is preferable to arbitrarily select the arrangement state, shape, etc. The flange portion 33 connects to the end portion 35 of the wall member 28 and the wall member 3 described later.
0 and the end portion 37 of the wall member 36 forming the passage 20.

These wall members 30, outflow holes 34, and flange portions 33 form a guide member 38 for the liquid 2.

The passage 20 also has an opening 23 that opens into the opening 22 of the passage 18, and an outlet 24 that is located away from the bottom 6, that is, below the opening 23. That is, the passage 20 is connected to the wall member 3 facing the wall member 30.
6 and an outer surface 40 of the wall member 30. Accordingly, the outlet 24 formed by the projecting end 41 of the wall member 36 is located further away from the bottom 6, i.e. below, compared to the projecting end 29 of the wall member 30, and the passage 20 directs the liquid 2 in the direction of the arrow 19. It can guide you in the direction shown. That is, the passage 18 and the passage 20 constitute a liquid passage. The liquid passage includes a passage 18 having an opening 21 opened at the opening end 16 and an opening 22 located above the opening end 16 to guide the liquid 2 above the opening end 16 of the mouth portion 15. and is configured to discharge the liquid 2 from the container body 3.

Wall member 36 is connected to inner surface 43 of columnar member 42 at end 37, as shown in FIG. One end 44 of the cylindrical member 42 is formed in such a shape that when the container 1 is placed in an inverted state, it can maintain the inverted state. The other end 45 of the cylindrical member 42 is preferably hermetically fixed to the outer surface 46 of the wall member 27 forming the wide mouth portion 25 of the mouth portion 15 by a threaded connection with a female thread. Instead of coupling by screwing the female and male threads together, it may be fixed by fitting.

These wall members 36, the outlet 24, and the cylindrical member 42 form a guide member 47 for guiding the liquid 2.

In this specific example, the surfaces of the wall members 30 and 36 of the aforementioned guide members 38 and 47 constituting the passage for the liquid 2 are formed to be flat, but depending on the aforementioned characteristics of the liquid 2, The shape of the surface may be, for example, a waveform, a groove, a depression, or a spiral unevenness.

Next, the operation of the container 1 according to this specific example will be explained.

In the state shown in FIG. 1, the liquid 2 contained in the container body 3
is the interior 5 of the container body 3 that acts on the liquid level 48 of the liquid 2.
The pressure of and the atmospheric pressure acting on the liquid level 49 are balanced,
Liquid 2 has not flowed out from container 1. When the container body 3 is pressed and deformed from this state, the above-mentioned pressure balance state with respect to the liquid 2 is broken, that is, the liquid level 48 of the liquid 2 is
The pressure in the interior 5 of the container body 3 acting on the liquid becomes greater than the atmospheric pressure acting on the liquid level 49, and the liquid 2 passes through the passage 20 over the opening 22 of the passage 18 and is poured out from the outlet 24. To go. Next, when the aforementioned pressure on the container body 3 is released, the container body 3 returns to its original shape due to the elastic force of the container body 3, and therefore the container body 3 acting on the liquid level 48
The pressure in the interior 5 of is reduced, and a portion of the liquid 2 remaining in the passage 20 is forced back into the passage 18 in the direction opposite to the direction indicated by the arrow 19, and the above-mentioned equilibrium condition is again achieved;
The liquid level 49 of the liquid 2 comes to be located at the passage 18 . Therefore, the liquid 2 does not remain in the passage 20, and will not leak even if the container 1 is placed upside down as shown in FIG.

Next, FIG. 5 shows a second specific example of a container having a liquid discharge mechanism according to the present invention. Note that in this second specific example, the container body 3 is the same as the first part shown in FIG.
Since it is the same as the specific example, it is omitted and only the entrance/exit portion 4 is shown.

As shown in FIG.
A mouth 15 is provided on the container body 3 to allow the liquid 2 stored in the container to enter and exit the container, and the liquid 2 from the mouth 15 is directed to the side opposite to the open end 16 of the mouth 15, that is, upwardly. A passage 18 configured to guide the liquid 2 in the direction indicated by the arrow 17 towards the bottom 6 of the container body 3 in which it is located and in a downward direction indicated by the arrow 19 opposite to the upward direction indicated by the arrow 17. and a passageway 20 configured to guide the user.

The mouth portion 15 includes a wide mouth portion 25 formed by a wall member 27 and a narrow mouth portion 26 formed by a wall member 28 fitted to the wall member 27. In this specific example, the wall member 27 and the wall member 28 are integrally formed, but it goes without saying that they may be formed as separate members.

The passage 18 has an opening 21 that opens at the open end 16 of the narrow portion 26 and an opening 22 that is located closer to the bottom 6 than the open end 16, that is, above the open end 16. That is, passage 18
is a surface 3 of a wall member 30 having a protruding end 29 facing the wall member 28 and forming an opening 22 together with the wall member 28;
1 and a surface 32 of the wall member 28.

Therefore, the protruding end 29 is closer to the bottom 6 than the open end 16 of the narrow part 26.
, the passage 18 is able to guide the liquid 2 in the direction indicated by the arrow 17 .

The passage 20 also has an opening 23 that opens into the opening 22 of the passage 18, and an outlet 24 that is located away from the bottom 6, that is, below the opening 23. That is, the passage 20 is defined by the surface 50 of the wall member 30. Therefore, the outlet 24 formed by the end 51 of the wall member 30 is located at a distance from the bottom 6, i.e. below, compared to the projecting end 29 of the wall member 30, and the passage 2
0 may guide the liquid 2 in the direction indicated by arrow 19.

The wall member 30 is connected to the inner wall 43 of the cylindrical member 42 at the end 37, as shown in FIG. One end 44 of the cylindrical member 42 is formed in such a shape that when the container 1 is placed in an inverted state, it can maintain the inverted state. The other end 45 of the cylindrical member 42 is preferably hermetically fixed to the outer surface 46 of the wall member 27 forming the wide mouth portion 25 of the mouth portion 15 by a threaded connection with a female thread. Instead of coupling by screwing the female and male threads together, it may be fixed by fitting.

The wall member 30, the outlet 24 and the cylindrical member 42 form a guide member for the liquid 2.

In addition, in the specific example of Mizutoshi 2, the wall member 30 of the guide member
Although the surfaces 31, 50, etc. of the above-mentioned first
Of course, it may be formed on an uneven surface as in the specific example.

The operation of this second specific example is the same as that of the first specific example described above, so a description thereof will be omitted. In addition, in the second specific example as well,
Of course, it is possible to use the means for adjusting the pressure in the interior 5 shown in FIGS. 2 and 3.

FIG. 6 shows a third embodiment of a container having a liquid ejection mechanism according to the invention. This third specific example also omits the container body 3 as in the second specific example described above,
Only the entrance/exit section 4 is shown.

In this third specific example, parts common to those in the above-described first specific example are indicated by the same reference numerals, and therefore a description of the common parts will be omitted.

As shown in FIG. 6, the difference between the third specific example and the first specific example is that the guide member 38 does not have a flange portion 33, and the wall member 30 is parallel to the wall member 28. In other words, it is at a point where it can move relatively in the direction shown by arrow 8. As shown in FIGS. 6 and 7, the surface 5 of the bottom 52 of the guide member 38
3 is provided with a plurality of protrusions 54. The protrusion 54 is
At the end of relative movement of the wall member 30 parallel to the wall member 28 in the direction indicated by the arrow, the surface 3 of the wall member 36
9 , so that a gap 55 is created between the surface 39 and the surface 53 of the bottom 52 of the guide member 38 .

This gap 55 forms a passage 57 through which the liquid 2 from the passage 20 can pass. Further, the guide member 38 is configured to move the wall member 30 at the end when the wall member 30 relatively moves parallel to the wall member 28 in the direction indicated by the arrow 14.
The projecting end 29 of the wall member 28 is configured such that it can come into contact with the surface 56 of the wall member 28 .

Note that instead of the protrusion 54 for securing the passage 57, a groove may be formed in the surface 53 of the bottom 52 of the guide member 38, and the groove may function as the passage 57. This passage 57 also functions as a passage for gas sucked from the outlet 24 when the interior 5 of the container 1 is brought into a negative pressure state. Also, the protrusion 54
The arrangement, shape, size, number, etc. can be arbitrarily selected as necessary.

Next, the operation of the container 1 according to the third specific example will be explained.

In the state shown in FIG. 6, similar to the state shown in FIG. 1 described above,
The liquid 2 in the interior 5 of the container body 3 does not flow out to the outside even when the container 1 is in an inverted state. By pressing and deforming the container body 3 from this state, the liquid 2 is transferred to the passage 18,
It sequentially passes through the passage 20, the passage 57, that is, the gap 55, and the outlet 24, and is poured out to the outside of the container 1. Next, the above-mentioned pressed state of the container body 3 is released and the container body 3 is deformed.
, the pressure in the interior 5 of the container body 3 is reduced and the liquid 2 present in the passage 20 is reversed and
The guide member 38 also moves in the direction indicated by the aforementioned arrow 14, and the protruding end 29 of the wall member 30 abuts the surface 56 of the wall member 28.

When this projecting end 29 comes into contact with the surface 56 of the wall member 28, the passage of the liquid 2 is blocked, and the projecting end 29
Surface tension is generated by the liquid 2 remaining between the projecting end 29 and the surface 56, which increases the close contact between the protruding end 29 and the surface 56, thereby making it possible to further improve the leakage of the liquid 2, that is, the sealing effect. The state in which the protruding end 29 and the surface 56 are in close contact with each other allows the container body 3 to be held in any state, i.e., inverted, upright, or sideways. It will not be released unless the pressure inside 5 is increased by pressing and deforming it.

Further, FIG. 8 shows a fourth specific example of a container having a liquid discharge mechanism according to the present invention. Like the third specific example, this fourth specific example also shows only the entrance/exit portion 4, and parts common to the first to third specific examples are designated by the same reference numerals and their explanations will be omitted.

As shown in FIG. 8, the difference in the fourth specific example from the third specific example is that the wall member 36 connected to the inner surface 43 of the cylindrical member 42 can be displaced in the direction shown by arrow 8. The reason is that it is formed into a diaphragm shape. This diaphragm-shaped wall member 36 is configured to maintain a shape as shown by a solid line in a normal state, and to maintain a shape as shown by a broken line when the pressure inside 5 of the container 1 increases to a predetermined value or more. There is a need.

Note that in this fourth specific example, similarly to the third specific example,
Using a guide member 38 having a protrusion 54 provided on the surface 53 of the bottom portion 52 so as to abut against the surface 39 of the wall member 36 and create a gap 55 between the surface 39 and the bottom portion 53 of the bottom portion 52. However, unlike the specific example of the cylinder 3, the wall member 36 is the eighth
Since it protrudes upward in the figure, the protrusion 54 needs to be placed in contact with the surface 39 of the wall member 36 at a position close to the outlet 24 of the wall member 36 in order to secure the gap 55. Yes.

Next, the operation of the container 1 according to the fourth specific example will be explained.

In the state shown in FIG. 8, the liquid 2 in the interior 5 of the container body 3 does not flow out to the outside even when the container 1 is in an inverted state. By pressing and deforming the container body 3 from this state, the diaphragm-shaped wall member 36 is deformed into the state shown by the broken line, that is, the state in which it gradually slopes downward in FIG. , so the liquid 2 is in the passage 18
, the passage 20, the passage 57, that is, the gap 55, and the outlet 24 in order, and is poured out to the outside of the container 1. Next, when the above-mentioned suppressed state of the container body 3 is released and the deformed container body 3 is returned to its original state, the wall member 36 is restored to its original state shown by the solid line and remains in the passage 20. At the same time as the liquid 2 flowing backwards, the guide member 38 also moves in the direction indicated by the above-mentioned arrow 14, and the protruding end 29 of the wall member 30 comes into contact with the end 56 of the wall member 28, as in the third embodiment. An even higher sealing effect can be ensured.

Further, FIG. 9 shows a fifth specific example of a container having a liquid discharge mechanism according to the present invention. Like the third specific example, this fifth specific example also shows only the entrance/exit portion 4, and parts common to the first to fourth specific examples are designated by the same reference numerals and will not be described again.

As shown in FIG. 9, the differences in the fifth specific example from the fourth specific example include a wall member 36 connected to an inner surface 43 of a cylindrical member 42 and a surface 53 of a bottom portion 52 of a guide member 38. Each is located at a point that gradually slopes downward in FIG. In other words, the passage 20 and the passage 57 continuous with the passage 20 are formed so as to gradually move away from the bottom 6 of the container body 3 from the opening 23 toward the outlet 24, that is, to be inclined. Therefore, when the pressed state of the container body 3 is released and the deformed container body 3 is returned to its original state, a portion of the liquid 2 existing in the passage 20 and the passage 57 flows back into the passage 18 and returns. Or, all the water flows downward along the inclined passage 57, and the passage 20
And it will not remain in the passage 57. Furthermore, in addition to the configuration of the container 1 of the fifth specific example, the passage 18 may also be configured to be inclined in the same way as the passage 20, as in the sixth specific example shown in FIG.

Note that the operations of the individual containers 1 in the fifth and sixth specific examples are the same as those in the third specific example described above, and will therefore be omitted.

Further, FIG. 11 shows a seventh specific example of a container having a liquid discharge mechanism according to the present invention. This seventh specific example also shows only the entrance/exit portion 4 as in the third specific example, and parts common to the first to sixth specific examples are designated by the same reference numerals and their explanations will be omitted.

In this seventh specific example, the guide member 47 and the mouth portion 15
The space 58 formed by the wall member 28 constituting the narrow mouth portion 26 and the guide member 38 are each formed into a spherical shape as shown in FIG. The bottom portion 52 of the guide member 38 is arranged such that the guide member 38 contacts the outlet 24 of the guide member 47 when the container 1 is in an inverted state as shown in FIG. It is formed to be thick so that it fits. Therefore, in each of the postures of the container 1, that is, the upright state, the inverted state, and the horizontally laid down state, the guide member 38 moves rotatably within the space 58, and the bottom portion 52 is positioned downward in each state. is configured to do so.

The operation of the container 1 of this seventh specific example is basically the same as that of the third specific example described above, but when the container 1 is laid down on its side, the guide member 38 is moved into the space 58. The protruding end 29 of the wall member 30 of the guide member 38
Any part of the surface 32 of the wall member 28 of the guide member 47
The difference is that the protruding end 29 comes into contact with the surface 32 of the wall member 28 to produce a sealing action.

Further, the guide member 38 in the various embodiments described above can be formed into various shapes as shown in FIGS. 12 to 18. In particular, the guide member 38 shown in FIG. 12 may be constructed such that an upper member 61 and a lower member 62 are combined as shown in FIGS. 19 and 20. In this case, by configuring the guide member 38 so that a gap 63 is created between the member 61 and the member 62, a return path for the liquid 2 to return under a negative pressure state can be secured. In this way, the guide member 38 shown in FIGS. 12 to 18 cannot secure the gap 63.
, the upper surface 5 of each guide member 38 in each figure
As shown in FIG. 21, it is preferable that a passage 60 for passing the liquid 2 is formed in each of the liquids 9 to secure the return passage. The number of these passages 60 is not limited to a plurality of passages, but may be half of them, and the arrangement and shape can be arbitrarily selected as required. Furthermore, it is preferable to similarly form a passage for the liquid 2 to pass through the lower surface 67 of each guide member 38 in each figure.

In addition, in the above-mentioned specific individuals, the narrow mouth part 26 is the wide mouth part 2.
5. However, the present invention is not limited to this, and as shown in FIG.
The tip portion 66 may be bent. The bending state of the tip portion 66, that is, the length angle, etc., can be arbitrarily selected. For example, it may be curved and a folded portion may be formed in the vertical direction or in the planar direction.

Further, in the specific individuals mentioned above, the exit 24 is connected to the guide member 4.
Although the columnar member 4 is provided on the bottom wall portion of the wall member 36 of No. 7, the present invention is not limited thereto.
It may be formed on the side wall portion of No. 2. Furthermore, the 22nd
As shown in the figure, when the guide member 38 shown in FIG. 12 is used, the liquid 2 becomes even more difficult to get wet regardless of the attitude of the container 1.

That is, although FIG. 22 shows the container 1 in an inverted state, when the container 1 is in a horizontal state, the liquid 2 remaining in either the right space 64 or the left space 65 in the internal space of the guide member 38 is When the device is in an upright position, the remaining liquid 2 accumulates in the upper right space 68 and the upper left space 69, thereby preventing the liquid 2 from leaking to the outside.

Furthermore, in each of the above embodiments, one liquid passage for the liquid 2 consisting of the passage 18, the passage 20 and the outlet 24 is provided for one container 1, but the present invention is not limited to this. A plurality of liquid passages may be provided in parallel. Further, like the tip portion 66, the liquid passage may be formed by arbitrarily selecting the bending state, length, angle, etc. so that the liquid 2 can pass in a wave-like manner in the vertical and horizontal directions.

It should be noted that the constituent members applied to each individual are not limited to the above-mentioned combinations, but can be combined in any manner.

Further, although the planar shape of each component in the above specific example is shown as circular, it goes without saying that other shapes such as angular and elliptical shapes can be taken.

Further, in each of the above-mentioned examples, the shape of the container body 3 is relatively long and vertically long, but this configuration is preferable from the viewpoint of preventing leakage of the liquid 2.

Finally, the ninth part of the container having a liquid discharge mechanism according to the present invention
Specific examples are shown in FIGS. 23 and 24. That is, the 23rd
A ring-shaped guide member 3 having a U-shaped cross section as shown in the figure.
8 is combined with the configuration of the second specific example shown in FIG. The ring-shaped guide member 38 has a groove 70 and is arranged so that the opening end 16 of the wall member 28 is accommodated in the groove 70. The operation of this specific example is basically the same as those of the previous specific examples, so a description thereof will be omitted.

In addition, in the specific individual, a part of the wall constituting the passage 20 near the outlet 24 is provided with a liquid retention part, for example, to prevent the liquid 2 attached to the wall from dripping. A recess may also be formed.

[Effects of the Invention] From the above configuration, the liquid discharge mechanism of the present invention can discharge a desired amount of liquid with a simple operation without causing liquid leakage,
