Description

siphon

The invention relates to a siphon that removes liquid from a container.

Regarding the mounting on the edge of the portable container, pouring the entire container can be like a bottle. A siphon for conveniently deriving a liquid has been shown in Example 2 of Patent Document 1.

In the above prior art embodiment, the capillary force of the liquid in the siphon is utilized in the siphon or pressure siphon state. Therefore, there is no need for special squeezing means, etc., and it has excellent movability and accommodability, and has no troubles, and is a very simple structure.

The pressure siphon as used herein refers to a state in which the liquid is smoothly taken out in the same manner as the siphoning state although gas remains in the siphon tube.

Hereinafter, in order to simplify the statement, the siphon or pressure siphon state is collectively referred to as a siphon state.

Further, hereinafter, the entire device including the flow path from the inside of the container to the liquid take-out port is referred to as a siphon.

The part of the flow path associated with the siphon state is called a siphon catheter for the sake of distinction. Means to be airtightly connected from the inside of the container to the outside of the container The part of the flow path up to the lowest part of the siphon.

[Patent Document 2] Japanese Patent Laid-Open No. Hei 11-243809

The above prior art embodiments have problems as shown below.

1. In use, especially when the amount of residual liquid in the container becomes small, if the container is inadvertently tilted in the opposite direction, the siphon interruption occurs immediately. At this point, you must make it siphon again, otherwise you will not be able to continue using it. When the next siphon state occurs, the last time the siphon interrupts the liquid remaining in the flow path, sometimes hinders the occurrence of the next siphon state. As a result, it is necessary to perform an operation of temporarily removing the siphon from the container and removing the liquid in the flow path. In the same situation, once the liquid in the container is taken out and the siphon state is completed, the same situation may occur when the liquid is added and used again.

2. In order to create a siphon state, the container must be tilted so that the liquid level in the container approaches the edge of the container. Due to the strength of the capillary force, the necessary attention will vary greatly, so the operation must be performed with care. When the environment is shaken in the car, the dark place where it is difficult to see the liquid surface, or the hand is shaken by cold or tension, there is a liquid overflow and there is a problem in accessibility.

3. The inner surface of the siphon to reach the capillary force that causes the siphon phenomenon must have a certain degree of hydrophilicity, so the materials that can be used are limited. Because the shape of the inner surface of the tube is in the siphon state The easiness of life also has an impact, and there are manufacturing problems such as processing methods and dimensional management.

4. As mentioned in the preceding paragraph, because the hydrophilicity of the inner surface of the siphon tube will affect the ease of use, the influence of dirt will also make the siphon state difficult to occur. Cleaning can make it recover, and if it is boiled, there is basically no problem. However, when cleaning with a detergent together with other foods, since the curved portion of the top of the tube is flat, it is difficult to clean with a fine brush.

The present invention has been made in view of the above points, and the following changes are applied to the prior art embodiments.

A. An intermediate liquid chamber is provided in the flow path outside the container to pursue the stability of the operation.

Since ancient times, the intermediate liquid chamber has been placed on a pipe transport path using a liquid having a high and low drop. It is used to buffer the flow fluctuation caused by the liquid flow state upstream or downstream and the influence of air mixing to stabilize the liquid flow.

In the present invention, the problem of the above 1. has an effect of delaying the occurrence of siphon interruption.

In use, when the container is tilted in the opposite direction, a countercurrent that exceeds the amount of liquid downstream of the lowest portion of the siphon occurs, and the gas sneaked into the lowest portion to form a siphon interruption.

The intermediate liquid chamber is provided from the lowest portion of the flow path outside the container toward the downstream side, so that the necessary reverse flow of the siphon interruption can be increased. As a result, if a reverse flow in a short time is obtained, the characteristic of siphon interruption does not occur.

The intermediate liquid chamber may be a liquid-filled type even if it is an open type in which gas can be stored in the upper portion during use. In the former case, it is better to communicate with the atmosphere at a position higher than the estimated liquid level. However, it is necessary to have a flow resistance of the gas to the extent that the function of the cylinder is not hindered by the following method.

B. A method in which a tube means is disposed outside the container to cause a negative pressure in the siphon tube to cause a siphon state.

A method of generating a siphon state using a cymbal means, for example, there are numerous proposals of Patent Document 2 and the like.

Even if liquid remains in the siphon, it can be forced to enter the siphon state. Therefore, it is not necessary to pay attention to the situation of liquid residue in the tube.

In addition, the material constituting the siphon duct is independent of the easiness of the siphon state as long as the airtightness and strength are necessary. It can be freely selected from temperature properties and liquid resistance which are suitable for use.

At the same time, in terms of shape, in particular, the degree of freedom in designing the curved portion of the top of the siphon is increased. Not only can it reduce manufacturing difficulty, but it also becomes a design that takes into account the cleanliness of the user.

The curved portion of the top portion of the siphon is air-tightly connected by a curved member having an obtuse angle, so that the inner diameter in the cleaning flow path such as a sponge can be provided, and the cleaning property can be further improved. In the prior art embodiment, when the state of the container is inclined and the flow path is located at a position several millimeters higher than the liquid level, the siphon state cannot occur. According to the invention of the cartridge method, the inner diameter can be enlarged without causing a problem.

Enlarge the inner diameter of the top of the siphon and also reduce the siphon Body flow resistance. Compared to prior art embodiments, it is easier to correspond to the application of fast take-up speed.

The suction capacity of the cylinder is larger than the volume of the siphon duct, and it is better not to be much larger than the necessary capacity depending on the form of the cylinder. Thereby, as described above, not only the problems 2, 3, and 4 of the prior art embodiments can be solved, but also the problem of inadvertent outflow of liquid or inconvenience of intrusion into the outer cylinder when the siphon state occurs can be reduced.

As in most conventional examples, the siphon state may not be entered due to the relationship between the outer side of the container of the siphon duct, the inner diameter of the descending portion, and the suction speed of the cylinder. This is because the liquid remains in the first place because there is too much air left at the top. It is possible to increase the suction speed of the cylinder or to reduce the inner diameter of the falling portion to correspond.

It is also a reasonable solution to attach the cylinder function to the aforementioned intermediate liquid chamber. In the aforementioned Patent Document 2 and the like, the flow path configuration is also the same. In the case of the configuration of the patent document type 2, since the container (sink) is of a fixed type, when it is desired to change the take-out speed, the height of the take-out port is changed. For example, consider taking out hot water from a container to make a drip coffee. It is hoped that the distance between the water inlet and the coffee powder will be kept close to a certain level to control the speed of water injection. In the case of the configuration of the patent document 2, the side of the drip tray on which the coffee powder is placed is moved up and down with the water injection port to move. A small amount of drip can be used in this way, and it is difficult to handle when using a large velvet bag with a large amount of dripping. In this case, the constitution of the present invention can be applied. As long as the water injection port is kept at the same height, the inclination of the container is changed, and even if the side of the drip tray is kept still, it is easy to control the speed of water injection. Because the container on the removal side is removable, it also contains the injection object. It is suitable for a wide range of applications when it is difficult to move.

According to the present invention as described above, the following siphon for liquid extraction is realized, and it is easy to start use in a bad environment, and when it is used under a little shaking, siphon interruption is less likely to occur, and cleaning after use is easy. There are fewer restrictions on the design and manufacture of materials and shape dimensions.

[Formation for carrying out the invention]

Hereinafter, an explanation will be given of an embodiment of the present invention with reference to the drawings. Although the structure in which the negative pressure is generated in the siphon duct is very diverse, here, for the principle of siphon generation in which the overall configuration of the siphon tube and the region where the negative pressure is generated are different, a configuration example in which nine users are relatively simple to operate is exemplified.

[Example 1]

Fig. 1 is a perspective view showing a state in which a siphon according to a first embodiment of the present invention is installed in a container, and Fig. 2 is a cross-sectional view showing a liquid flow path in the same state. Here, the cup of the 1 series liquid container, the casing of the 13 series siphon, includes the intermediate liquid chamber and the cartridge of the present invention. The casing 13 is attached to the cup 1 by means of the inner portion 111 of the siphon duct 2 shown in Fig. 2 and the fins 110 of the casing 13. The hose for the outlet of the liquid is 14. The 15 series frame is used to fix the outlet 14 to the height of the edge of the cup 1 and, at the same time, as shown in the following description, to assist the function of the cylinder 13 of the casing 13. As shown in Fig. 2, the siphon duct 2 is configured to hermetically connect the inner portion 111 of the container and the outer portion 12 of the container to ensure the ease of cleaning. The housing 13 is a flexible container that connects the body portion 114 and the lid portion 112. The siphon duct 2 is assembled by being inserted or the like so as to pass through the lid portion 112. The root portion of the outlet 14 is taken out and connected to the outlet of the lower portion of the casing body 114 in an airtight manner. In the casing cover portion 112, there is a small hole 113 for the purpose of atmosphere communication. However, if the connection between the casing body 114 and the lid 112 and the connection between the lid 112 and the siphon duct 2 are moderately communicated with the atmosphere, the small holes 113 are not required.

The housing 13 takes the form of being able to remove and house the siphon duct 2, the outlet 14 and the frame 15 when not in use, which is advantageous for carrying. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In the second diagram showing the initial state, the liquid 0 is only located in the cup 1. In the siphon duct 2, there is also only a liquid level 102 which is substantially the same height as the liquid level 101 in the cup 1.

Next, the cylinder function assisting operation of the frame 15 will be described with reference to Fig. 3 . The configuration will be described in the third (A) diagram. The side plates on both sides of the 115 frame 15 cover the case body 114 and the take-out port 14 from left and right. On the side plate 115, there are guide members 116, 117, a claw member 119, and a cushion 118 for squeezing the hose of the outlet 14 when actuated. With the housing body 114 and the springs 120, 121, the side panels 115 are generally maintained at an interval that is parallel to the width of the housing body 114. The operation of the frame 15 having the above configuration will be described with reference to the third (B) and (C) drawings. For ease of viewing, the springs 120, 121 are omitted from the illustration.

When the side plate 115 is equally pressed in the direction of the white arrow in the third (B) diagram, first, the casing body 114 is pressed. Further pushing, under the guidance of the guiding members 116, 117, the interval between the side plates 115 is narrowed, and the take-out port 14 is finally pressed by the pad 118 to be locked. Further, the claw member 119 is fitted to be in the state of the third (B) diagram.

At this time, when the force of the white arrow is released, the side plate 115 should return to the original position under the restoring force of the casing body 114 and the springs 120 and 121. However, under the hindrance of the claw member 119, the restoration on the left side of the figure is delayed. When the state of the third (C) is reached, the claw member 119 is disengaged, and thereafter, the state returns to the state of the third (A). In the process from the 3rd (B)th to (C), the take-out port 14 continues to maintain the locked state.

The operation of the first embodiment will be described using the above configuration.

In order to cause the siphon state from the state of FIGS. 1 and 2, the user first pushes the frame side panel 115. Thereby, the casing body 114 is pressed, and the internal gas is discharged to the outside through the small opening 113 of the outlet 14 and the casing cover 112 which have not been latched. When the side plate 115 is finally pushed to the bottom, the outlet 14 is closed and becomes the state of the third (B). This action does not cause too much change in the liquid surface, and the flow path profile maintains the appearance of Fig. 2 except for the vibration.

Next, when the user releases the side plate, the volume of the casing main body 114 increases while the take-out port 14 is in the locked state until the state of the third (C) diagram. The liquid 0 in the cup 1 is attracted by the negative pressure generated in the housing 13 and the siphon tube 2. Liquid 0 is filled with a siphon catheter to form a siphon state. It becomes the flow path section shown in Fig. 4. The liquid level 102 in the siphon duct 111 enters the housing body 114 and becomes a transitional liquid level 103. Since the gas flowing in from the small hole 113 is opposed to the recovery speed of the casing body 114, the suction of the liquid 0 is dominant. After the housing body 114 is restored, the liquid level 103 in the housing body 114 continues to flow through the small holes 113 to reach the same level as the liquid level 101 in the cup 1.

When the claw member 119 is disengaged and the side plate 115 is returned to the initial state, the lock of the take-out port 14 is released, and the flow path sectional view is as shown in Fig. 5. By. The liquid level 103 in the housing body 114 and the liquid level 104 on the side of the outlet 14 are stably at the same level as the liquid level 101 in the cup 1.

Fig. 6 is a cross-sectional view showing the state in which the liquid 0 is taken out each time the cup 1 is tilted after the siphon state is stabilized. When the front end of the outlet 14 is inclined to a position lower than the liquid level 101 in the cup 1, the take-up stream 105 occurs. The liquid level 103 in the casing body 114 is also slightly lowered corresponding to the take-up speed.

According to this embodiment, after the siphon tube is mounted on the cup, the operation of pushing the frame side plate 115 with one hand and releasing the frame side plate 115 can be in a siphon state. If the fixing action of installing the siphon tube in the container is linked with the frame operation, it is more convenient to use. In addition, since there is no valve mechanism or the like in the flow path of the liquid, fatal failure is less likely to occur. When the mechanism of the frame 15 is lost, both hands are required. However, the same cylinder operation and blocking operation as in Fig. 3 can be easily performed manually. Moreover, it is not only the siphon duct 2, but the housing 13 can also be divided, so that it is very easy to clean. When the housing main body 114 and the outlet 14 are configured to recognize the internal liquid surface from the outside, they can be used as an indicator of the amount of residual liquid when they are placed flat. In the first embodiment, a configuration example in which a negative pressure is generated in the entire open liquid chamber and the siphon duct is shown. The compression release case 13 itself will be described as an example. However, a siphon tube having the same principle as that of other forms such as suction may be added to the additional cylinder.

[Embodiment 2]

Fig. 7 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a second embodiment of the present invention is placed in a container. Siphon catheter 2, here, is inside the container The portion 210, the outer container upper portion 22, and the outer container lower portion 211 are formed of three members. All of the flow path members from the siphon catheter 2 to the soft cartridge liquid chamber 23 and the outlet port 24 are hermetically connected. A small valve 212 having a specific gravity smaller than that of the liquid is disposed at the downstream side outlet of the cartridge chamber 23. By the action of the valve 212, the operation of the cylinder chamber 23 is performed as long as it is compressed and released.

This figure shows a liquid level in a steady state after the siphon state occurs, and the liquid level 203 in the outlet 24 is at substantially the same level as the liquid level 201 in the cup 1.

When not in use, the above-mentioned flow paths are decomposed and stored, cleaned, and maintained. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

When the cylinder liquid chamber 23 is compressed in a state where the liquid is only present in the cup 1, the gas in the chamber is discharged to the outside through the valve 212. When the cartridge liquid chamber 23 is released, the restoring force causes a negative pressure in the liquid chamber and the siphon catheter 2. The valve 212 is closed, and the liquid 0 in the cup 1 is sucked out and reaches the lower portion of the cartridge liquid chamber 23 to become a siphon state. The operation after the siphoning state is substantially the same as that of the first and third embodiments, and thus the description thereof will be omitted.

According to the present embodiment, the mechanism of the frame 15 of the first embodiment is not required, and the holding member (not shown) can be simplified. It is more convenient to use the siphon tube to fix the movement of the container in conjunction with the operation of the cartridge liquid chamber. The cartridge chamber 23 is a sealed intermediate chamber in which no gas is stored in the upper portion during operation. Valve 212 may also be located closer to the downstream than the position of the figure. Configuration The optimum position between the cylinder chamber 23 and the front end of the outlet port 24 can also be selected in a preferred manner. If the internal liquid level can be visually confirmed by both the cartridge liquid chamber 23 and the outlet port 24, the same as in the first embodiment, and it can be used as a confirmation index of the residual liquid amount when it is placed flat. In the second embodiment, a configuration example in which a negative pressure is generated in the entire intermediate liquid chamber of the sealed type and in the siphon duct is shown. Although the compression release cylinder liquid chamber 23 itself is described as an example, a siphon tube having the same principle as that of other forms such as suction may be added to the additional cylinder.

[Example 3]

Fig. 8 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a third embodiment of the present invention is placed in a container. Here, the cup of the container of the 1st liquid 0, the inner part of the container of the 2 series siphon catheter, and the outer portion 32 of the siphon catheter are hermetically connected to form a siphon catheter. 33 series intermediate liquid chamber. The height of the outer portion 32 of the siphon catheter and the bottom of the cup 1 is hermetically connected to the take-up tube 34 from above. The tube 34 is taken out and has a height-opening outlet at the edge of the cup 1. The connecting member from the siphon duct 2 to the take-out tube 34 is held by the cup 1 by a holding member (not shown). The intermediate liquid chamber 33 is provided with the following members constituting the cylinder mechanism. The piston 310 is slidable up and down in the intermediate liquid chamber together with the slide plate 311. The spring 324 pushes the piston 310 toward the top of the liquid chamber. The piston 310 has an opening corresponding to the joint portion of the take-up tube 34 on the side above the liquid surface. The motor drive unit 312 rotationally drives the guide shaft 314 when the switch 313 is pressed. The power supply, motor, and control circuit are partially sealed. Bearing 315 holds the guide shaft 314 and the spring 324 in the lower portion of the liquid chamber. There is an open hole configuration that does not interfere with the flow of the liquid. For the purpose of sliding plate operation to be described later, the opening pin 317 is disposed on the motor driving portion 312, and the closing pin 318 is disposed on the bearing 315. The 316 is a top cover of the intermediate liquid chamber for fixing the components in the intermediate liquid chamber 33, corresponding to The portion for the purpose of operation of the switch 313 is composed of soft material.

When not in use, the above-described respective flow path connections can be removed and stored, the top cover 313 can be removed, and the members in the intermediate liquid chamber 33 can be taken out to perform simple cleaning and maintenance. The shape and configuration of each member shown in the drawings are for convenience of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In Fig. 8 showing the initial state, the liquid 0 is only located in the cup 1. Even in the siphon duct 2, there is only a liquid level 302 which is substantially equal to the level 301 of the liquid level 301 in the cup 1.

Next, the switching operation of the slide plate 311 will be described with reference to Fig. 9. Fig. 9(A) is an initial state diagram of the piston 310 and the slide plate 311 when they are positioned above the liquid chamber. The state observed from above. The piston 310 has a notch 324 which moves up and down in the case where it is restrained in the rotational direction in accordance with a track (not shown) on the inner surface of the intermediate liquid chamber 33. Further, an opening hole 322 and a closing hole 323 corresponding to the opening pin 317 and the closing pin 318, and a slit 319 indicated by a broken line are formed. The two sliding plates 311 are formed by a rail (not shown). The surface of the 310 is slidably mounted, and has a guiding portion 321 which follows the thread groove of the guiding shaft 314 and a slit 320 indicated by a solid line. The sliding plate 311 can utilize the opening pin 317 and the closing pin The 318 performs the sliding shape and is located at two positions. In the ninth (A) diagram of the initial state, the opening pin 317 is inserted into the opening hole 322, the two sliding plates 311 are approached, the guiding portion 321 is engaged with the guiding shaft 314, and the slit 320 is overlapped with the slit 319 on the piston side to form Opening. When the state of the ninth (B) diagram is moved below the liquid chamber, the closing pin 318 is inserted into the closing hole 323, the two sliding plates are retracted, and the guiding portion 321 is retracted from the center without being restricted by the guiding shaft 314, and the slit The 320 is located at a position offset from the slit 319 on the piston side to form a lock.

The operation of the third embodiment will be described using the above configuration. In order to enter the siphon state from the state of Fig. 8, the user pushes the switch 313. The motor drive unit 312 rotates the guide shaft 314, and the piston 310 and the slide plate 311 in the state of FIG. 9(A) are driven in the downward direction of the liquid chamber while following the screw groove compression spring 324. Figure 10 shows the state of reaching the lowermost part of the liquid chamber. Here, the slide plate is driven by the closing pin 318. Up to now, since the slits 319, 320 of the piston 310 and the slide plate 311 are lowered in the case of forming an opening, the movement of the gas is not hindered, and the liquid surface does not change too much. The liquid surfaces 301 and 302 are located at the same position as the initial position except for the vibration. When the function of the closing pin 318 is in the state of the ninth (B) diagram, the piston 310 and the slide plate 311 are separated from the guide shaft when the slit is closed, and are pushed back above the liquid chamber by the action of the spring 324. When the slit is in the locked state, the gas between the upper and lower sides of the piston 310 does not move rapidly, and the negative pressure is generated in the lower portion of the piston 310 of the intermediate liquid chamber 33 and in the siphon ducts 32 and 2, and the siphon state in which the liquid 0 is derived is generated. Figure 11, the piston 310, the sliding plate 311 back to the beginning At the beginning position, the liquid level shows a steady state. The liquid surface 303 in the intermediate liquid chamber 33 is located at substantially the same height as the liquid surface 301 in the cup 1. Fig. 12 is a cross-sectional view showing the liquid 0 taken out each time the cup 1 is tilted after the siphon state is stabilized. The take-up stream 305 occurs when the take-out port is tilted to a position lower than the liquid level 301 in the cup 1. The liquid level 304 in the intermediate liquid chamber becomes the height of the outlet. The top cover 313 can be completely sealed, or can be connected to the atmosphere at a position higher than the height of the predicted liquid level. The liquid level 304 of Fig. 12 is completely sealed. The liquid level 304 when the atmosphere is connected is close to the height of the liquid level in the cup 1.

According to this embodiment, after the siphon tube is installed in the cup, the siphon state can be generated as long as the switch is activated. The intermediate liquid chamber 33 and the take-out tube 34 can be used as an indicator of the amount of the residual liquid when the internal liquid level can be recognized from the outside. In the third embodiment, the sealed or open type intermediate liquid chamber has a cylinder function, and a configuration example in which a negative pressure is generated in one of the intermediate liquid chambers and the siphon duct. The above description is directed to an example in which a guide shaft and a piston are used. However, an axial flow pump of an appropriate size and performance may be substituted to constitute a siphon of the same principle.

[Example 4]

Figure 13 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a fourth embodiment of the present invention is placed in a container. The cup of the container of the 1st liquid 0, the inner part of the container of the 2 series siphon catheter is hermetically connected to the outer portion 42 of the siphon catheter to form a siphon catheter. 43 series intermediate liquid chamber. The height of the aforementioned siphon duct, at the outer portion 42 of the container and the bottom of the cup 1, above The square is hermetically connected to the take-up tube 44. The take-up tube 44 has a height at the edge of the cup 1 to form an open outlet. The connecting member from the siphon duct 2 to the take-out tube 44 is held by the cup 1 by a holding member (not shown). The intermediate liquid chamber 43 is provided with the following members constituting the cylinder mechanism. The piston 410 is a ring magnet connected to the switch plate 411 and the leaf spring 412, and moves up and down in the intermediate liquid chamber 43. The spring 414 has a lower end supported by a rib 416 on the inner surface of the liquid chamber to push the piston 410 upward. The 413-series magnet slides down the surface of the intermediate liquid chamber 43. The top cover portion of the 415-type intermediate liquid chamber 43 seals the liquid chamber and prevents the magnet 413 from coming off.

When not in use, the respective flow path connections can be decomposed and stored, and the top cover 415 can be removed, and the magnet 413 and the members in the intermediate liquid chamber 43 can be taken out to perform simple cleaning and maintenance. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In Fig. 13 showing the initial state, the liquid 0 is only located in the cup 1. There is also only a liquid level 402 in the siphon duct 2 that is substantially the same height as the liquid level 401 in the cup 1. The piston 410 is positioned above the liquid chamber by the action of the spring 414, and the mutually repulsive magnet 413 is located above the piston 410. The switch plate 411 is slightly separated from the piston 410 by the action of the leaf spring 412.

Next, the configuration of the switch board 411 will be described with reference to Fig. 14. The switch plate 411 has an opening 417 and a projection 418 that projects into the central opening of the piston 410 and faces downward. Stopping and facing downward of piston 410 During the movement, under the action of the leaf spring 412, the piston 410 is slightly separated, and the central opening of the piston 410 and the opening 417 of the switch plate 411 form a gas or liquid flow path. In the upward movement of the piston 410, the projection 418 of the switch plate 411 slightly closes the central opening of the piston 410, so that the flow path is substantially closed.

The operation of the fourth embodiment will be described using the above configuration. In order to enter the siphon state from the state of Fig. 13, the user pushes the magnet 413 downward. Thereby, the mutually repulsive pistons 410 are interlocked to move downward, and the spring force of the spring 414 is increased. The piston 410 moves downward, and as described above, the flow path of the gas is ensured, because there is no pressure change in the siphon, and the liquid level 402 does not largely change. The piston 410 is further moved downward, and if the repulsive force of the spring 414 is dominant, the piston 410 is reversely moved upward. Figure 15 is a cross-sectional view of the process. Since the piston 410 moves upward, the gas flow path is substantially blocked, and a negative pressure is generated below the piston 410 and in the siphon ducts 42 and 2, thereby discharging the liquid 0. The liquid level in the siphon duct transitions through the position of 403, and a siphon state occurs. Since the operation after the siphon state occurs is substantially the same as in the first and third embodiments, the description thereof will be omitted. The magnet 413 that has been pushed down, after use, returns to the original position and is used for the next time. The rib 416 on the inner surface above the liquid chamber becomes a stopper of the piston and can return to the initial position under mutual exclusion. The rib 416 on the inner surface above the liquid chamber can be removed, and the maintainability is not damaged.

According to this embodiment, after the siphon tube is mounted on the cup, the siphon state can be generated as long as the magnet 413 is pushed downward. The intermediate liquid chamber 43 of this embodiment is a closed type liquid chamber filled with a liquid in use. intermediate When the liquid chamber 43 and the take-out tube 44 are configured to recognize the internal liquid surface from the outside, they can be used as a confirmation index of the amount of residual liquid when they are placed flat. In the fourth embodiment, the sealed intermediate liquid chamber has a cylinder function, and a negative pressure is generated in a portion of the intermediate liquid chamber and the siphon conduit. An example of a piston using a magnet will be described. However, an axial flow pump of an appropriate size and performance may be substituted to constitute a siphon of the same principle.

[Example 5]

Figure 16 is a cross-sectional view showing the liquid flow path of the siphon starting process of the fifth embodiment of the present invention. Here, the 1st liquid 0 container cup, the inner part of the 2 series siphon catheter, and the outer portion 52 of the siphon catheter are hermetically connected to form a siphon catheter. The 53-type intermediate liquid chamber has a switchable cover portion 510. The outer portion 52 of the aforementioned siphon duct is assembled by inserting the cover portion 510 or the like. The take-out pipe 54 is airtightly connected to the outlet of the lower portion of the intermediate liquid chamber 53, and has an open outlet at a height to the edge of the cup 1. The cover portion 510 further has a small hole 511 for the purpose of atmosphere communication. However, the attachment portion of the cover portion 510 and the connection between the cover 510 and the siphon duct 52 do not require the small hole 511 as long as the atmosphere is appropriately communicated. The connecting member from the siphon duct 2 to the take-out tube 54 is held by the holder 1 by a holding member (not shown). The 512 is a negative pressure cylinder composed of a soft material, and is inserted into the take-out port substantially airtight.

The intermediate liquid chamber 53 is a form in which the connection of the above-described members can be removed when not in use, and the purpose is to facilitate carrying. The number of components of this configuration is small, and cleaning and maintenance are very simple. The shape of each component shown, The configuration is merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

The operation of the fifth embodiment will be described using the above configuration. After the siphon is installed in the cup, the user performs an operation of inserting the cartridge 512 into the take-out port in order to cause the siphon state. When the cartridge is compressed, if it is compressed at a faster rate than the gas discharge from the orifice 511, the gas may be discharged from the opening of the siphon catheter 2 in the cup 1. When the suction amount of the cylinder 512 is not sufficient, it is preferable to wait a little while. Excess gas is discharged from the small holes 511, and the liquid level in the siphon duct 2 is substantially equal to the liquid level in the cup 1. This problem can be avoided by inserting the cartridge 512 in a compressed state in advance. When the compression of the cartridge is released, a negative pressure occurs in the siphon, and the liquid 0 is led out to become a siphon state. The liquid surfaces 502 and 503 of Fig. 16 are in a siphon state, and the liquid surface exhibits a transition state before stabilization. When the liquid surface 502 in the intermediate liquid chamber 53 reaches above the outlet of the extraction tube 54, it rises by the velocity of the gas discharged from the small hole 511. The liquid level 503 in the take-out tube 54 rises as the suction speed of the cylinder 512 rises. The operation after the siphoning state is substantially the same as that of the first and third embodiments, and thus the description thereof will be omitted.

According to this embodiment, after the siphon tube is mounted on the cup, the siphon state can occur as long as the cartridge 512 is inserted into the take-out opening. Most of the transmissions are carried out by means of sucking the mouth by mouth, and this configuration is preferable from the safety surface and the sanitary surface. Further, there is no valve mechanism or the like in the flow path of the liquid, and a fatal failure is unlikely to occur. In the present embodiment, the intermediate liquid chamber 53 of Fig. 16 is an open type liquid chamber in which a gas is stored in the upper portion. In the middle of liquid removal The liquid level in the inter-liquid chamber is slightly lower than the liquid level in the cup 1 . When the intermediate liquid chamber 53 and the take-out tube 54 are configured to recognize the internal liquid surface from the outside, they can be used as a confirmation index of the amount of residual liquid when placed in a flat position.

Fig. 17 is a cross-sectional view showing a liquid flow path of a starting process using another configuration example of the same principle as the embodiment. The difference from the above is the intermediate liquid chamber 533 which is hermetically connected to the siphon duct 522 underneath. The switchable cover portion 513 has a closed type that is filled with liquid during use, and the take-out tube 544 is still airtightly attached to the upper portion of the airtight lock cover. In the present configuration, since the atmosphere is not communicated in the flow path, the cylinder 512 is inserted and inserted in advance, and the operation of siphon generation is permitted in a case where the suction capacity is increased to enter the gas in the cup 1. The liquid surface 504 of Fig. 17 is the case after the occurrence of the siphon state and before the stabilization. If it is possible to monitor the configuration of the liquid level before stabilization, it is easy to prevent the liquid from intruding into the cylinder due to excessive suction. Because the rise of the liquid level is more moderate than in the 16th figure of the rise of the thin take-up tube. Pull the tube 512 out and take it out to stop the suction.

In the fifth embodiment, a configuration in which a negative pressure is generated in the entire intermediate liquid chamber and the siphon tube by suction from the take-up tube is used. The description will be made by way of an example of a syringe in the form of a syringe. However, it may be configured as a siphon of the same principle as other types of cylinders such as an electric cylinder. Further, a siphon tube having the same principle can be constructed by attaching an axial flow pump of an appropriate size and performance to the take-out tube.

[Embodiment 6]

Figure 18 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a sixth embodiment of the present invention is placed in a container. Here, the 1 series liquid 0 container cup The inner portion of the container of the 2-series siphon catheter is hermetically joined to the outer portion 62 of the siphon catheter to form a siphon catheter. The lower portion of the outer siphon duct 62 of the container is a soft member. The 63-type intermediate liquid chamber has a groove for accommodating the soft portion of the siphon duct 62 at the lower portion, a soft portion for the purpose of switching operation to be described later, and a bearing to be described later on the inner surface. The take-up tube 64 is hermetically connected to the outflow port at the lower portion of the intermediate liquid chamber 63, and has an outlet for opening to the edge of the cup member 1. The connecting member from the siphon duct 2 to the take-out tube 64 is held by the cup 1 by a holding member (not shown). The intermediate liquid chamber 63 is provided with the following members for constituting the cylinder mechanism. Please also refer to Figure 19 of the liquid chamber section for frontal observation. The runner 610 has a plurality of rollers 611 on the circumference, and has the function of a rotor of a hose cylinder. The runner 610 is configured to rotate integrally with the bevel gear 618, and is held by a long bearing 612 provided in the inner liquid chamber surface with the rotor shaft 619. The rotor shaft 619 is slidable along the shape of the long bearing 612, and in the initial state, under the restoring force of the siphon duct 62, approaches the left side of Fig. 18. The motor drive unit 613 rotationally drives the drive shaft 615 under the pressing of the switch 614. The power source, the motor, and the control circuit portion are sealed, and the switch 614 can be externally operated by the soft portion of the lower portion of the aforementioned intermediate liquid chamber. The power supply is preferably an inductive rechargeable battery. The drive shaft 615 has the other end held by a bearing 617 installed in the intermediate liquid chamber, and the bevel gear 616 is rotated to drive the bevel gear 618 and the runner 610.

The intermediate liquid chamber 63 is configured to be capable of removing and connecting the respective flow paths when not in use, which is advantageous for carrying. Moreover, the member shown in Fig. 19 is unitized and can be taken out from the intermediate liquid chamber, which is advantageous for the dimension. Protection. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In Fig. 18, which shows the initial state, liquid 0 is only present in the cup 1. Within the syphon catheter 2, there is also only a liquid level 602 that is substantially the same height as the liquid level 601 in the cup 1.

Referring to Fig. 20 which shows a cross section of the liquid flow path in the starting process, the operation of the sixth embodiment will be described with reference to the above configuration. After the siphon is mounted to the cup, the user pushes the switch 614 for the siphon state to occur. The rotation of the motor drive unit 613 is transmitted to the bevel gear 616. Under the driving force, the runner 610 first moves along the long bearing 612 in the direction of the squeeze siphon duct 62, and then rotates in the direction of the arrow. The drum 611 is sequentially rotated from top to bottom while forming a sealed portion of the siphon duct 62, and a negative pressure is generated in the siphon ducts 63 and 2 to extract the liquid 0 to the outside of the cup 1. The liquid level in the siphon duct transitions through the position of 603 and a siphon state occurs. After the siphon state occurs, the switch 614 is released, that is, there is no driving force, and the siphon duct 62 pushes the runner 610 back under the action of the restoring force to secure the flow path. Since the operation after the siphon state occurs is substantially the same as in the first and third embodiments, the description thereof will be omitted.

According to this embodiment, after the siphon tube is installed in the cup, the siphon state can be generated by only one switch. The intermediate liquid chamber 63 is an open type in which a gas is stored in the upper portion. The cover may be provided. However, if the upper portion is sealed, the liquid level in the liquid chamber may not rise, and the flow of the liquid 0 may be unstable. Therefore, it is preferable to appropriately perform atmospheric communication. Intermediate liquid chamber 63 and When the tube 64 is taken out, the internal liquid level can be recognized from the outside, and it can be used as a confirmation index of the amount of residual liquid when it is placed flat. In the sixth embodiment, the siphon duct has a configuration example of a cylinder function. Only negative pressure can occur in the siphon catheter. The intermediate liquid chamber can also be of a closed type. The above description is made using an example of using a motor, however, the hose barrel can also be constructed manually. Further, an axial flow pump of an appropriate size and performance may be substituted to constitute a siphon of the same principle.

[Embodiment 7]

Figure 21 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a seventh embodiment of the present invention is placed in a container. Here, the 1st liquid 0 container cup, the inner portion of the 2 series siphon catheter, and the outer portion 72 of the siphon catheter are hermetically connected to form a siphon catheter. The 73-type intermediate liquid chamber has an inner side wall formed by a parallel plane (not shown), and an inner bottom surface of an arc shape in a part of the left-right direction of the figure, and the siphon duct 72 is hermetically connected to the inner wall of the cup 1 side. A cross-shaped rib 714 and a sliding bearing 712 for supporting the starter plate 710 to be described later on the inner side wall. The take-out pipe 74 is an air outlet which is airtightly connected to the lower portion of the intermediate liquid chamber 73, and has an outlet which is open to the edge of the cup 1 to a high degree. The connecting member from the siphon duct 2 to the take-out tube 74 is held by the cup 1 by a holding member (not shown). The intermediate liquid chamber 73 is provided with the following members for constituting the cylinder mechanism. Please also refer to Figure 22 of the liquid chamber section for frontal observation. The starter plate 710 has a shape in which the rib 714 is inscribed in the inner surface below the intermediate liquid chamber 73, and is held by the protrusion 711 on both sides to the sliding bearing. 712. The spring 713 pushes the starter plate 710 and the projection 711 toward the upper left end of the slide bearing 712 when tilted as shown. With the projection 711 in this position, the lower end of the starter plate 710 floats from the inner bottom surface of the intermediate liquid chamber 73, and the surface of the starter plate 710 on the container side does not contact the rib 714.

It is preferable to have a structure in which the above components can be removed and simple cleaning and maintenance are performed. The intermediate night room 73 is in a form that can be removed and accommodated in the above-mentioned components when not in use, and is advantageous for carrying. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In Fig. 21, which shows the initial state, the liquid 0 is only located in the cup 1. In the siphon duct 2, there is also only a liquid level 702 which is substantially the same height as the liquid level 701 in the cup 1.

With the above configuration, the operation of the seventh embodiment will be described with reference to Figs. 23 and 24 of the liquid flow path section of the starting process. After the siphon is mounted on the cup, in order to cause the siphon state, the user pushes the knob portion of the upper end of the starter plate 710 toward the cup 1 side. Under this operation, the projection 711 is moved to the lower right end of the sliding bearing 712, and at the same time, the lower end of the starter plate 710 contacts the inner bottom surface of the intermediate liquid chamber 73, and the side of the container of the starter plate 710 abuts against the rib 714. The rib portion 714, the inner surface of the intermediate liquid chamber 73, and the starter plate 710 can form a substantially sealed space including the opening of the lower end of the siphon duct 72. Fig. 23 is a cross-sectional view showing a state in which the starter plate 710 is pressed to the substantially center. By expanding the substantially closed space, a negative pressure is generated in the sealed space itself and in the siphon ducts 2, 72, and the liquid 0 is led out to the outside of the cup 1. The liquid level in the siphon duct 72 drops The siphon state occurs and transitions to the aforementioned confined space through the position of 703. Fig. 24 is a cross-sectional view showing a state in which the starter plate 710 is pushed to the bottom. The lower end of the starter plate 710 is separated from the arcuate section of the bottom surface of the intermediate liquid chamber 73 and floats from the inner bottom surface. Up to now, the sealed space has been opened, and the liquid surface 704 in the intermediate liquid chamber 73 and the liquid surface 705 in the take-out pipe 74 have risen in a stable state. The operation after the siphoning state is substantially the same as that of the first and third embodiments, and thus the description thereof will be omitted.

According to this embodiment, after the siphon tube is installed in the cup, the siphon state can be generated as long as the operation of the starter plate is pushed. The intermediate liquid chamber 73 is an open type in which the upper portion stores the gas during use. The cover may be provided. However, since the upper portion is sealed, the liquid level in the liquid chamber may not rise, and the flow of the liquid 0 may be unstable. Therefore, it is preferable to appropriately perform atmospheric communication. When the intermediate liquid chamber 73 and the take-out pipe 74 have a configuration in which the internal liquid surface can be recognized from the outside, it can be used as a confirmation index of the amount of the residual liquid when it is placed flat. In the seventh embodiment, the open type intermediate liquid chamber has a cylinder function, and a negative pressure is generated in a portion of the intermediate liquid chamber and the siphon conduit. The above description is made by taking a solid-state starting plate as an example. However, the restoring force of the elastic member can also be used to constitute a siphon of the same principle.

[Embodiment 8]

Fig. 25 is a cross-sectional view showing the liquid flow path in a state before the start of the siphon of the eighth embodiment of the present invention. Here, a cup of a liquid 0 container, a container part of a 2-series siphon catheter, which is hermetically connected to a container outer portion 82 of the siphon duct to form a siphon catheter, and has a lower end having a structure as will be described later. Made. 83 series intermediate liquid chamber. The take-up tube 84 is hermetically connected to the outlet of the lower portion of the intermediate liquid chamber 83, and has an open outlet at a height to the edge of the cup 1. The connecting member from the siphon duct 2 to the take-out tube 84 is held by the cup 1 by a holding member (not shown). In the present configuration, the following members for constituting the cylinder mechanism are provided. Please also refer to Fig. 26 which shows the cross section of the intermediate liquid chamber 83 when viewed from the front. The 811 is a negative pressure cylinder composed of a soft material, and is operable from above the intermediate liquid chamber 83, and the suction port 810 is coupled to the upper portion of the opening of the lower end of the siphon conduit 82 in a relatively opposing manner. At the lower end of the siphon duct 82, a membrane valve 812 made of a soft material is provided. The lower end of the siphon duct 82 and the cylinder suction port 810 are as shown in the front view of Fig. 26, and the flat opening of the same width is used to secure the cross-sectional area of the flow path, and the opening height of the siphon duct 82 to the intermediate liquid chamber 83 is narrowed. In order to stabilize the operation of the membrane valve 812. In order to simplify the drawing, it is not shown in Fig. 26, however, the film valve 812 is attached in such a manner as to span the entire width of the flat portion on the lower side of the opening of the siphon duct 82.

It is preferable to have a structure in which the above components can be removed and simple cleaning and maintenance are performed. The intermediate liquid chamber 83 is in a form that can be removed and accommodated in the above-mentioned members when not in use, and is advantageous for carrying. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

In the 25th view in which the cartridge 811 is in a compressed state, the liquid 0 is present only in the cup 1. When the cartridge is compressed, since the valve 812 is in the open state, the gas is discharged from the opening and the outlet of the upper portion of the intermediate liquid chamber, and the liquid level 802 in the siphon conduit 2 does not change too much. In addition to vibration, roughly The same height as the liquid level 801 in the cup 1 is used.

With the above configuration, the operation of the eighth embodiment will be described with reference to Figs. 27 and 28 of the liquid flow path section of the starting process. After the state of Fig. 25, the user releases the compression of the cartridge 811 in order to cause the siphon state. Fig. 27 is a cross-sectional view showing a state in which the cylinder 811 is restored to the middle. With the negative pressure generated by the cartridge 811, a negative pressure is generated in the siphon ducts 2, 82, and the membrane valve 812 is brought into a closed state attached to the cartridge suction port 810, and the liquid 0 is led out to the outside of the cup 1. The liquid level in the siphon conduit 82, descending and siphoning, transitions through the position of 803 to the lower end of the siphon conduit 82 and the cylinder suction port 810. Fig. 28 is a cross-sectional view showing a state in which the cylinder 811 is completely restored. When the negative pressure disappears and the liquid 0 reaches the lower end of the siphon duct 82, the membrane valve 812 is opened. In the intermediate liquid chamber 83 and in the take-out tube 84, the liquid surfaces 804 and 805 rise toward a steady state. Sometimes, excess liquid 0 will invade the cartridge 811. The operation after the siphoning state is substantially the same as that of the first and third embodiments, and thus the description thereof will be omitted.

According to this embodiment, after the siphon tube is installed in the cup, the cylinder 811 is operated to be in a siphon state. For example, if the type of compression and liberation of the cylinder is used, and the fixing action of the siphon to the container is linked with the operation of the cylinder, it is more convenient and preferable to use. The intermediate liquid chamber 83 is an open type in which gas is stored in the upper portion during use. The cover may be provided. However, since the upper portion is sealed, the liquid level in the liquid chamber may not rise, and the flow of the liquid 0 may be unstable. Therefore, it is preferable to appropriately perform atmospheric communication. The intermediate liquid chamber 83 and the take-out tube 84 are externally identifiable When the internal liquid level is formed, it can be used as a confirmation indicator of the amount of residual liquid when it is placed flat.

Fig. 29 is a cross-sectional view showing the liquid flow path in an initial state in the other configuration examples by the same principle as the present embodiment. Here, the outer portion 822 of the siphon catheter is attached to the upper end of the lower end, and is adjacent to the upper end of the drawing, and is coupled to the suction port 813 of the cartridge 814. Further, at the opening of the lower end of the siphon duct 822, a membrane valve 815 of a switch siphon duct 822 is provided. In this configuration, although the siphon state is generated by the operation of the cylinder 814 and the liquid 0 is derived, if the cup 1 is tilted in advance at the time of starting, the suction port 813 is positioned lower than the liquid level 801 in the cup 1. In the use method, it is possible to cause the siphon state only by the action of the cylinder 814. The connection of the suction port 813 and the siphon duct 822 is as close as possible to the lower side, which is advantageous for the siphon state. Compared with the configuration of Fig. 25, it can be a simpler configuration. Valve 815 can also be located slightly above the figure. It is disposed at the optimal position between the lower end of the siphon duct 822 and the suction port 813, and the valve mode can also select the optimum. In application, a check valve is added upstream of the connection of the suction port 813 and the siphon duct 822, and may be configured to be in a siphon state by a plurality of operations of the cylinder 814, such as a kerosene cylinder type. At the time of starting, it is not necessary to tilt the cup 1 and the cylinder 814 can be miniaturized. At this time, the area and principle of occurrence of negative pressure are also the same.

In the eighth embodiment, a configuration example in which a negative pressure is generated in the siphon duct by the outer cylinder is used. The intermediate liquid chamber can also be of a closed type. The description will be made by using an example of a syringe in the form of a syringe. However, a siphon having the same principle as other cylinders such as an electric cylinder may be constructed.

[Embodiment 9]

Figure 30 is a cross-sectional view showing a liquid flow path in a state in which a siphon according to a ninth embodiment of the present invention is installed in a container. Here, the 1 is a liquid 0 container cup, and the 2 is a siphon catheter inside the container. The 910 is a cylinder made of a soft material, and the siphon duct 2 and the outer lower portion 92 of the siphon duct are airtightly connected, and the knob 911 is pressed to perform a compression operation. The siphon catheter is formed by two siphon catheters 2, 92 and a cylinder 910. At the opening of the lower end of the siphon duct 92, a membrane valve 912 of a single switch siphon duct 92 is provided. 93 is an intermediate liquid chamber. The take-out pipe 94 is an air outlet which is airtightly connected to the lower portion of the intermediate liquid chamber 93, and has an outlet for opening to the edge of the cup 1 to be opened. The connecting member from the siphon duct 2 to the take-out tube 94 is held by the cup 1 by a holding member (not shown).

The above components can be removed and easily cleaned and maintained. Further, the intermediate liquid chamber 93 is configured to accommodate the above-described members when not in use, and is advantageous for carrying. The shape and configuration of each member shown in the drawings are merely for the purpose of explanation. Actually, it is possible to adopt a configuration that is convenient in use, optimum shape in manufacturing, and division.

With the above configuration, the starting operation of the ninth embodiment will be described with reference to Fig. 31 showing a cross section of the liquid flow path in the starting process. After the siphon is mounted on the cup, the user pushes the knob 911 of the cartridge 910 toward the cup 1 side in order to cause the siphon state. During the compression of the cartridge 910, the liquid 0 is only located within the cup 1. When the cartridge is compressed, since the valve 912 is in the open state, the gas is discharged from the upper portion of the intermediate liquid chamber and the outlet port. Out, the liquid level 902 in the siphon catheter 2 does not change too much. In addition to the vibration, it is substantially the same height as the liquid surface 901 in the cup 1. Fig. 31 is a cross-sectional view showing the state in which the user releases the compression of the cartridge 910 and the cartridge 910 is in a state of restoration. Due to the negative pressure generated by the cylinder 910, a negative pressure also occurs in the siphon ducts 2, 92, the membrane valve 912 is closed, and the liquid 0 is led out to the outside of the cup 1. The liquid 0 entering the cartridge 910 from the siphon catheter 2 is retained in the cartridge, for example, forming a liquid surface 903. When the inner diameter of the siphon conduit 92 is slightly greater, exchange of liquid within the cartridge and gas within the siphon conduit 92 may occur, for example, forming liquid levels 904,905. When the recovery of the cartridge 910 is substantially completed and the negative pressure is released, the valve 912 is in the open state. At this time, if the potential energy of the liquid in the outer flow path of the cup 1 is larger than the amount of liquid 0 remaining in the cylinder 910, the liquid 0 descends toward the lower end of the siphon duct 92. When the inner diameter of the siphon duct 92 is not excessively large, no gas enters and the liquid 0 is prevented from falling, and a siphon state occurs. Depending on the conditions of the shape of the cylinder or the like, all of the gas in the cylinder 910 and the siphon ducts 2, 92 may be discharged to the intermediate liquid chamber 93 or the take-out tube 94. Figure 32 is a cross-sectional view showing a siphon state and a steady state after the start-up action. An example of a pressure siphon state in which gas remains on the flow path. The liquid level 906 in the intermediate liquid chamber 93 and the liquid surface 907 in the take-up tube 94 are the same height as the liquid surface 901 in the cup 1 . The gas remaining in the flow path forms a liquid surface 908 in the siphon duct 2 and a liquid surface 909 in the cylinder 910. As described above, if all of the gas is discharged, it is completely in the siphon state and becomes the liquid surface 908, 909. Figure 33 and Figure 34, after the siphon state is stable, each tilting the cup 1 To perform a cross-sectional view of the liquid 0 take-out. Figure 33, when the tilt of the cup 1 is small. When the outlet is tilted to the position of the liquid level 901 in the cup 1, the liquid drops 9078. The liquid level 9066 in the intermediate liquid chamber 93 is located at the same or slightly lower level than the liquid surface 901. In the siphon duct, a gas remains in the upper portion of the siphon duct 2 and the cylinder 910 to form a supply path for the liquid 0, for example, to form a liquid level of 9099. Figure 34, when the cup 1 is tilted large. When the outlet is inclined to a position lower than the liquid level 901 in the cup 1, a liquid take-out stream 9079 occurs. The liquid surface 9067 in the intermediate liquid chamber 93 is lower than the liquid level 901 in the cup 1 and the intermediate height higher than the height of the take-out port depending on the flow resistance condition. In the siphon duct, the gas is in a state of being pressed downward due to the flow of the liquid 0, for example, forming a liquid level such as 9098. At the point of this, the gas is sometimes discharged to the intermediate liquid chamber 93 at the point of the flow.

According to this embodiment, after the siphon tube is installed in the cup, the cylinder 910 can be operated to siphon. It is a very simple composition. For example, if the type of compression and liberation of the cylinder is used, and the fixing action of the siphon to the container is linked with the operation of the cylinder, it is more convenient and preferable to use. The cartridge 910 can also be located further below the figure. When the cartridge 910 is located lower than the liquid level 901 in the cup 1, until the cartridge 910 is fully restored, the siphon state may occur, increasing the chance of full siphoning. Valve 912 can also be located further above the figure. The optimal position between the lower end of the siphon duct 92 and the cylinder 910 can also be selected. In application, a check valve is added upstream of the cylinder 910, and may also be a kerosene cylinder type, which is a plurality of operations of the cylinder 910. The composition of the siphon state occurs. The miniaturization of the cartridge 910 can be achieved, and in addition, the cartridge can be disposed above the siphon catheter. The intermediate liquid chamber 93 is an open type in which the upper portion is used to store the gas. The cover may be provided. However, since the upper portion is sealed, the liquid level in the liquid chamber may not rise, and the flow of the liquid 0 may be unstable. Therefore, it is preferable to appropriately perform atmospheric communication. When the intermediate liquid chamber 93 and the take-out pipe 94 have a configuration in which the internal liquid surface can be recognized from the outside, it can be used as a confirmation index of the amount of the residual liquid when it is placed flat.

Embodiment 9 is the same as Embodiment 6, in order to make the siphon duct have a configuration example of the cylinder function, however, depending on the conditions, all the processes up to the siphon state are not completely determined by the action of the cylinder function. example. Only negative pressure can occur in the siphon catheter. The intermediate liquid chamber can be of a closed type. Although the compression liberation cylinder 910 itself is described as an example, the cylinder 910 may be simply used as a liquid retention chamber and may be suctioned by a separate cylinder to constitute a siphon of the same principle. At this time, in the same manner as in the eighth embodiment, a configuration in which a negative pressure is generated in the siphon duct by the external cylinder is used. Depending on the conditions, all the processes up to the siphon state are not completely determined by the operation of the cylinder function. .
