Description

  The present invention is a siphon cup that is optimal for science experiments formed using the so-called siphon principle.

The present invention is basically a siphon cup that applies the principle of siphon.
Therefore, first, the siphon principle that is widely known (the inventor is said to be Alexandria's engineer, Kutesibios who thought about a water clock, etc.) together with a schematic diagram attached for reference in FIG. First, an outline of the principle 50 will be described.
In FIG. 10, when the water in the container A is now transferred to another container B, the hose is bent into an inverted J shape as shown in the figure, and the height of the drainage port H is made lower (Z) than the intake port S, If the water in the hose is once sucked from the outlet H side and led beyond the maximum portion T, the container edge higher than the water surface of the container A or the highest portion T of the hose is exceeded without using a pump. Water can be transferred continuously to container B. This is the principle of siphon.
The principle of the siphon is also used on a daily basis, for example, when using a hose to pull gasoline from a car fuel tank into another container, or draining water from the bath tub beyond the rim. However, the principle is also applied to products such as flush toilets, refrigerators, and cooling devices, and so-called “coffee siphon” as a coffee kettle is famous.

Although the patent documents related to the present invention were not found in the search results of the prior art disclosed, the background art is introduced and described together with an illustration in the following Non-Patent Document 1 as “The Commanding Trap”. It seems that the contents of the kite based on the siphon principle are closely related to the present invention. Therefore, the description is quoted together with the schematic diagram introduced as “Commander's Trap” in Non-Patent Document 1 below, and the principle of siphon (including the principle and phenomenon of siphon is described below) (This may also be referred to simply as siphon), and is also used as a reference for understanding the contents of the present invention, which will be described later. The contents will be quoted for explanation.
Illustrated Ancient and medieval supertechnology 38 Tatsuo Ogura Kodansha Bluebacks C. Around the 1st century (pages 46-53)

In order to elucidate the difference between the content of the “command of the commandment” described in Non-Patent Document 1 and the content of the siphon cup according to the present invention, the ancient Greek (B.C. 1st century) C.) With regard to the “commander's trap” said to have been devised by Heron, the illustration and explanation content introduced with illustrations in Non-Patent Document 1 are cited and attached to FIG. 11 and described below. .
The graphical illustration in Fig. 11 is introduced as a "commander's trap" that teaches the lesson that if you drink too much liquor recommended by others, it will flow out from the bottom of your base ... As described in the same literature, ceramic tea bowls with the same mechanism are manufactured and sold in Ishigaki City, Okinawa as mysterious tea bowls and belly eight-minute tea bowls. When I went sightseeing, I already obtained it and cut and dismantled the inside.

The “commander's trap” in the above document is sufficiently useful for understanding the contents of the siphon cup according to the present invention, which will be described later. First, a supplement is added as appropriate together with the illustration of FIG. 11 cited from the above document. I will explain. In addition, all the liquids handled below are demonstrated as water.
11a to 11d show cross-sectional views of the ridge, and for the ridge that has been drilled in the bottom surface of the cup as shown in FIG. 11a, a reverse J-shaped tube is inserted between the water inlet and the heel bottom as shown. And insert it into the bottom hole of the trough so that the drain port is lower than the intake port so that water does not leak. The simple mechanism described above is what is called the “Commander Trap”.
Now, let us explain the situation when water is poured into the finished kite, along with an illustration.
Fig. 11b ... Until the water level reaches the highest point of the reverse J-tube, water rises simultaneously in the ridge and reverse J-tube.
Fig. 11c ... When water is poured until the water surface exceeds the top of the inverted J tube, the water suddenly flows out from the drain of the inverted J tube.
Fig. 11d ... Once flowing out, the water continues to flow even if the water injection is stopped or the water surface is lower than the highest part, and all of the water flows out until the water intake is separated from the water surface.

Furthermore, as the theory that Heron talked about the principle of siphon, the illustrations and explanations described in the above literature will be helpful for the understanding of siphon. To.
11e, f ... When the outlet A of the inverted J-shaped tube is equal to the water surface B, no flow occurs even if the inverted J-shaped tube is filled with water. This is because the weight of water in the AC and BC parts in FIG.
11g, h... However, when the outlet A becomes lower than the water surface as shown in FIG. G, the weight of water between AD is added as shown in FIG. H, so the weight between AC is heavier than the weight of water between BC. As a result, the water is pulled to the outlet A side and continuously flows out. (The above is the content cited in the above document as Heron's theory.
By the way, it is the reason why the water flows continuously. In FIG. 11g, after the water between the AC flows out, if the water remains in the pipe between the BCs or the water between the BCs flows backward, The space is created and the water is cut off, the point C is brought into a vacuum state, and the atmospheric pressure acting on the water surface B pushes the water between the BCs toward the vacuum part of the point C. However, in reality, the water in the inverted J-shaped tube is balanced in force by the weight of the water at any point, so that the point C is not evacuated and the water continues to flow continuously.

Therefore, the siphon cup based on the principle of the siphon targeted by the present invention is based on the function and operation of the inverted J (U) -shaped tube that has been widely introduced as a component of the siphon in various materials, starting with Non-Patent Document 1. In view of the above, it is an object of the present invention to improve the main part of the siphon configuration that has been known since ancient times so as to be suitable for the purpose of teaching science experiments.
In other words, in view of the inverted J-shaped pipe that has been bent and fixed, the water can be drained into the cup so that a wide variety of siphon experiments can be performed using a single siphon cup by dividing the intake section and the drain section into two parts. It is an object and an object of the present invention to provide a siphon cup in which the water intake pipe can be exchanged as a mode in which the water intake pipe formed in a separate body and covered with the drain pipe is covered with the drain pipe.

In order to solve the above problems, the siphon cup according to the present invention is configured as follows.
The siphon cup according to the first aspect of the present invention has a cup provided with an opening for water injection at one end and a drain outlet at the bottom of the other end as follows. That is,
The lower end of the drain pipe opening is penetrated to the outside of the bottom surface of the cup to form a drain outlet, the upper end of the drain pipe is formed lower than the end of the cup opening, and the drain pipes of the both end openings are connected to the cup. Using a cup that is formed upright from the bottom inside the cup, processed with the drainage pipe,
A water intake pipe to be attached to the cup is processed separately as follows. That is, the inner diameter of the intake pipe is larger than the outer diameter of the drain pipe, and when the intake pipe is covered with the drain pipe, the inner upper end of the intake pipe is higher than the upper end of the drain pipe. Using the intake pipe processed by having hermetically formed with a higher dimension, forming an intake opening at the lower end of the opening of the intake pipe,
However, the siphon cup is based on the principle of the siphon configured to cover the drain pipe that is separately processed with respect to the drain pipe that is formed upright in the cup.

A siphon cup according to a second aspect of the present invention includes a column attached to a pedestal in the siphon cup according to the first aspect of the present invention, a balance bar supported by the column via a rotation fulcrum, and suspended from at least one end of the balance bar. A cup-type balance comprising the siphon cup attached in a shape,
However, in connection with water injection and drainage into the siphon cup, the siphon cup is based on the principle of siphon configured so that the balance can perform balanced and unbalanced balance operations.

The siphon cup of the third invention has an inner diameter of the cup opening so that a substantially upper half of the golf ball protrudes when the official golf ball is inserted into the opening of the cup in the siphon cup of the second invention. Processed dimensions, the golf ball inserted into the opening, abutted against the upper end of the intake pipe so that the golf ball is supported, and the golf ball inserted into the opening A presser ring that is fitted in the outer peripheral edge portion of the opening in the state and is made detachable to prevent the golf ball from coming off,
However, the golf ball that protrudes from the opening of the cup is supported by the upper end of the intake pipe and is rotatably held by the opening of the cup. It is a siphon cup based on the principle of the configured siphon.

In recent years, it has been pointed out that the youth and others are away from science in Japan, and since 2002, the Ministry of Education, Culture, Sports, Science and Technology has been striving to improve learning for science and technology through measures such as the “Science and Technology Love Plan”. The present invention relates to a siphon cup devised so as to provide an optimum experimental teaching material particularly for a siphon experiment.
Interesting and interesting in a wide variety of siphons for elementary and junior high school students (which will be described below in conjunction with the drawings of each embodiment), including a siphon cup according to the present invention and a cup-type balance (fourth embodiment) described below. Through experimental experiments on magical elements, we will provide experimental teaching materials that will arouse curiosity of science among young people and enhance the learning effect of science.

That is, the siphon cup according to the present invention uses a cup that is integrally formed with a drain pipe standing up through the cup, as will be clarified in the specification together with the drawings of the embodiments. As a result of the one-touch exchange with intake pipes with different intake port S gap dimensions, various siphon experiments were made possible.
On the other hand, by configuring the intake pipe so that it can be exchanged, when the different kind of intake pipe is dropped into the cup after pouring water into the cup, an experiment to ask what happens to the water inside the cup (see FIG. 4), etc. Probably, with regard to those siphons, we propose a siphon cup that enables unique experiments that the inventor Heron and the predecessors of the “Commander's Trap” (see FIG. 11) may not have thought of (see Reference) The internal structure of the belly eight minutes tea bowl that is manufactured and sold in Ishigaki city is a structure based on the reverse J-shape similar to the configuration disclosed in the literature 1 as a result of the actual dismantling investigation by the applicant, It was verified that the structure is different from the cross-sectional view of FIG. 1e).

Conventionally, a typical illustration widely introduced in many documents and materials as an explanatory diagram of a siphon is attached to FIG. 10, and further, an illustration of “The Commander Trap” cited from the non-patent document is shown in FIG. 11. Cited above. That is, as an illustration of the structure of the siphon principle, there is usually an illustrative view in which an inverted J-shaped tube or an inverted U-shaped tube is fixedly formed on the bottom surface of the cup container. Conventionally, the drainage pipe and the intake pipe are configured as separate bodies, or without being divided, the reverse J-shaped siphon pipe that is bent and integrated is inserted into and fixed to the container to prevent water leakage.
For example, in a siphon constructed by the known siphon principle using a reverse J-tube fixed type such as “Commanding Spear”, a simple function spear that is just an interesting goods can be realized, but the experimental teaching material as intended by the present invention As a result, functionally satisfactory results could not be obtained and the purpose could not be met.
On the other hand, when processing a coffin with the structure disclosed in the “Commander's Coffin”, it is difficult to form the J-shaped tube, and the container cup and the J-shaped tube are separately processed and then assembled into a press-fitting or bonding process. Secondary processing is essential.
The siphon cup of the present invention relates to the siphon configuration (structure) completely different from the known technology using the J-shaped tube, and in addition to the excellent experimental function for teaching materials, all the components are cylindrical. As a tubular body, it can be easily molded with plastic and has a great manufacturing feature that does not require any secondary processing such as adhesion.

An outline of the effect features of the main embodiment will be described below.
The structural features of the siphon cup according to the present invention are representatively shown by the first embodiment (FIGS. 1 to 4). That is, in order to achieve the object of the present invention, in the first embodiment, as shown in each drawing of FIG. 1, in a cup provided with a bottom having one end closed and an opening at the other end, a drain pipe having both ends opened. The lower end of the opening is penetrated from the bottom of the cup to the outside to be a drain outlet, and the upper end side of the drain pipe is made lower than the cup to form the drain pipe integrally with the cup 1.
On the other hand, the intake pipe having a water intake opening provided at the lower end of the opening and having a water intake at the lower end of the opening is higher than the drain pipe, and the inner diameter is larger than that of the drain pipe 4, and the intake pipe 6 is processed separately. As shown in FIGS. 1f to h, the lower end of the opening is prepared with a different size of the notch gap G. However, the main feature of the siphon cup structure of the present invention is that the intake pipe 6 is covered with the drain pipe 4 as shown in the cross-sectional view of FIG. This is performed at the bottom surface 3 below the surface of the water that is not affected by atmospheric pressure, and the intake pipe 6 can be attached and detached with one touch.

  As a result of the invention of the structure of the above-mentioned main points, it is possible to realize a wide variety of siphon experiments based on the siphon principle (<Experiment 1>: FIG. 2 to <Experiment 3>: see FIG. 7), and the structure is simple and production It is a siphon cup that has excellent performance, is unique, has playground equipment, and has solved its problems. This siphon cup is preferably molded as a transparent body (clear) so that the internal structure of the cup and the condition of water injection / drainage / retention water can be seen from the outside, especially when it is carried out for the purpose of experimental teaching materials. Further, when colored water is used as necessary, a so-called contrast agent effect is exhibited and a further effect as an experimental teaching material is exhibited. (See FIGS. 1 to 4).

  According to the siphon cup of the best embodiment of the second embodiment according to the present invention, in connection with processing a plurality of water intakes at the lower end of the intake pipe 6 as shown in each drawing of FIG. A plurality of intake pipes processed into one intake pipe 6 can be switched in rotation as shown in FIG. 5c, or a plurality of intake pipes with different intake openings can be connected in the horizontal and vertical directions as shown in FIGS. 5d and 5e. In the second embodiment of the siphon cup, the intake pipe S of the above-described mode is used and the intake port S is switched.

According to the siphon cup of the best embodiment of the fourth embodiment according to the present invention, at least the balance bar with respect to the balance bar supported via the rotation fulcrum from the column attached to the base as shown in FIG. A balance having a siphon cup according to the present invention attached to one end of the present invention in a suspended form and configured as shown in FIG. 7 is a cup-type balance of the fourth embodiment.
That is, in connection with the water injection and drainage to the siphon cup attached to one side of the cup-type balance 20 in a suspended manner, together with the siphons described in detail in the respective illustrations of FIG. The cup-type balance 20 enables two-stone experimental learning including balanced and unbalanced operating principles, and is optimal as an experimental teaching material that enhances the learning effect.

  According to the siphon cup of the best embodiment of the fifth embodiment according to the present invention, when the official golf ball is inserted into the opening of the cup as shown in FIG. 8, the substantially upper half of the golf ball is protruded. The inner diameter of the cup opening is processed so that the inserted golf ball is in contact with the upper end of the water intake pipe, and the lower edge of the golf ball is supported. The presser ring 44 is used to prevent the golf ball from being detachable so that the presser ring is fitted to the outer peripheral edge of the cup opening. The cup is also used as a handle of the massager. This is the fifth embodiment.

That is, when not used as a siphon cup, the cup 1 is also used as a handle, protrudes from the cup opening, is supported by the upper end of the intake pipe, and smoothly rolls in the 360 ° direction to the cup opening. This is a held golf ball type massager. As shown in FIG. 8d, the golf ball is pressed and rolled to the skin portion that requires massage by grasping the handle (cup), and several hundred dimples (recesses) formed on the surface of the golf ball. ) Is a massager that can enhance massage and acupressure effects.
In addition, the massage device of the present embodiment allows the golf ball 43 to be freely exchanged, so that it can also be used for storage of so-called my balls or commemorative golf balls that are hole-in-one, a golf player's golf competition and a high addition with playground equipment It can be done with value products.

Now, the contents of the siphon cup according to the present invention can be easily understood by referring to the explanation contents of the siphon described above together with FIG. 11 cited from the attached diagram of FIG. 10 and the non-patent document 1. Prior to the description of each embodiment, the main points of the siphon cup according to the present invention will be listed below with reference to the drawings.
<Configuration points of siphon cup>
1. As shown in FIG. 1, in the cup 1, a drain pipe 4 having both ends opened is formed upright from the bottom of the cup and is integrally formed through the cup.
2. On the other hand, the separate intake pipe 6 of FIG. 1B forms a water intake S by sealing the upper end 6t and providing a notch gap at the lower end of the opening.
3. As shown in the cross-sectional view of FIG. 1e, the drain pipe 4 is set in such a manner that the intake pipe 6 is covered from the outside. This completes the siphon cup.

4). On the other hand, two types of interests with different results can be obtained by preparing a type in which the notch gap G of the intake pipe 6 shown in FIGS. A siphon experiment is possible.
5). Further, when each intake pipe is set to drop into the drain pipe from the state where water is poured into the cup 1 up to the upper end T of the drain pipe 4, a third interesting siphon experiment is possible.
6). When a cup-type balance (FIG. 7, the fourth embodiment) is configured by suspending the siphon cup on one side of a separately configured balance mechanism, the balance is related to the siphon accompanying water injection and drainage. It is also ideal for teaching teaching of the equilibrium and unbalance principles.
7). In addition, as shown in the fifth embodiment of FIG. 8, the golf ball set in the opening 2 of the cup 1 of the siphon cup is rolled on the end of the water pipe and is prevented from coming off by a presser ring, and the cup is subjected to ball massage. A massage device is constructed by combining it with the handle of the device, and it becomes a siphon cup that further enhances added value like two birds with one stone.

In the present specification, in order to make it easy to understand the contents of the configuration, the same reference numerals and the same names are assigned to the elements having the same configuration and the same action, and specific embodiments will be described below with reference to the drawings. First of all, a major feature in the production of the component parts of the siphon cup of the present invention is that it is essentially a plastic material as an upright tubular (pipe) body without requiring secondary processing such as adhesion and press-fitting of the parts after processing. Molding can be performed with high productivity and can be carried out at low cost.
Furthermore, in order to achieve the objective as a science experiment teaching material for young people, it is transparent so that the internal structure of the cup 1, the drain pipe 4, and the intake pipe 6 and the internal situation during intake and drainage can be observed from the outside. (Clear), plastic such as acrylic, ABS, PC, etc., it is desirable to mold as a transparent body, or to form a translucent body to the extent that the inside can be seen through even if it is slightly colored for design reasons. Accordingly, the internal perspective line portions in the external perspective view in the drawings of the present application are all shown in a distinguishable manner using thin lines by solid lines.

The first embodiment of the siphon cup according to the present invention will be described with reference to FIG.

Therefore, the cup 1 in FIG. 1a has an opening 2 at one end, and the drainage pipe 4 has a height h1 from the closed bottom surface 3 at the other end as shown in the sectional view of FIG. Depending on the height, a drain outlet H having an upper end T opened and a lower end penetrating to the outside of the bottom surface 3 is formed. Further, the drain pipe 4 is connected to the base portion of the cup 1 from the bottom surface 3 as shown in FIG. The shape is formed upright together with a plurality of reinforcing ribs 5. The embodiment shown in FIGS. 1a to e is an embodiment in which three reinforcing ribs 5 are provided, and FIG. I is an embodiment in which four reinforcing ribs 5 are provided.
Further description will be continued with respect to the first embodiment of FIG. FIG. C shows a state in which the water intake pipe 6 is picked up as shown in FIG. B and the portion 7 is picked up and is simply placed on the bottom surface 3 so as to cover the drain pipe 4 of the cup 1, and FIG. The figure is shown. When the drain pipe 4 is placed so as to cover the intake pipe 6 from above, the lower end of the inner diameter of the intake pipe 6 is guided by the reinforcing rib 5 so that the drain pipe 4 and the intake pipe 6 are connected as shown in FIGS. The relational dimension between the root of the reinforcing rib 5 and the inner diameter d3 of the intake pipe 6 is set so that the shaft centers substantially coincide.

Here, the specific principal part dimension of 1st Example is described based on FIG. The dimensions of each part in FIG. 1e are the height dimension h1 = 45 (unit: mm) from the bottom surface 3 of the drain pipe 4, the internal height of the intake pipe 6 (height from the lower end of the opening to the upper end of the seal) h2 = 48, Cup 1 internal height h3 = 70, drainage port H inside diameter d1 = φ4, drainage pipe 4 outside diameter d2 = φ8, intake pipe 6 inside diameter d3 = 14, cup 1 opening 2 (bottom constriction) inside diameter It is carried out with d4 = φ40. Next, the example dimensions of the water intake S of the water intake pipe 6 will be described. The width dimension W of the notch gap S = 5, the gap height dimension G = 7 in FIG. F (this is G = L type), and the gap height dimension G = 2 in FIG. G (this is G = S type). ), The gap height dimension G = 0 in FIG. H is the intake pipe 6 without a notch (this is G = 0 type).
The cross-sectional view of FIG. 1e shows a cross-sectional view of a state in which the knob portion 7 of the intake pipe 6 of FIG. Moreover, although each Example when the one intake port S of the above intake pipe 6 was provided was shown, for example, the intake port S is opposed to two places or three places every 120 °, and further to four places. It may be provided, and the result is substantially the same when a plurality of water intakes S are provided.

Next, FIGS. 1i to k will be described. The intake pipe 6 of the above-described embodiment has been shown in the embodiment in the case where it is not particularly prevented from coming off when being set in the drain pipe 4, but, for example, at a predetermined location related to the reinforcing rib 5 of the drain pipe 4 as shown in FIG. When the concave portion 9 is processed as shown in the drawing, the convex portion 35 is formed at the corresponding position of one intake pipe 6 as shown in the sectional view of FIG.

FIG. I shows an embodiment in which there are four reinforcing ribs, and FIGS. I and j show the upper end of each as a cut surface 10.
<Experiment 1>

Now, an outline of the experimental results of the first embodiment will be described with reference to the drawings.
Hereinafter, in order to make the contents of the siphon cup easier to understand in this patent application, siphon experimental conditions and results are also shown in the drawing together with the drawings, and described as <Experiment 1> to <Experiment 3>. It should be noted that the main purpose of the siphon of the present invention as an experimental teaching material can be sufficiently understood through Experiment 1, Experiment 2, and Experiment 3 in the first embodiment.

With regard to Experiment No. 1, the experimental situation will be listed and described together with the respective drawings in FIG.
1. FIGS. 2A to 2C show the experimental situation of the siphon when the G = 7 type (notch height 7 mm) of the intake pipe 6 is set in the siphon cup shown in the first embodiment.
In this siphon cup, a water level line 8 is printed on the outer periphery of the cup, and the water level line 8 is injected with approximately 50 cc of water from the opening 2 with the intake pipe 6 set on the cup 1 as shown in FIG. 11 shows a water level line 8 corresponding to the water level at 11 when the siphon operates. In conclusion, in the experiment of FIGS. 2A to 2C, the water in the cup is not drained 12 from the drain outlet H at the time of water injection below the water injection line in FIG.
However, when water is poured over the water level line, almost all of the water in the glass 1 is drained 12 from the drain H in about 7 seconds in the embodiment illustrated in FIG. On the bottom surface 3, about 2 to 3 mm of water always remains in the following experiment as well. Also, if this experiment is carefully observed, a plurality of bubbles will beep as the air is taken in from the intake S at the end of drainage and water is pushed out from the intake pipe 6 to the drain H of the drain pipe 4. Drained and air flows into both pipes.

2. FIGS. 2d to g show siphon experimental conditions when G = 2 type (notch height 2 mm) is set as the intake pipe 6 in the siphon cup. The result of this experiment is a siphon different from the result of item 1 above. That is, in the first water injection for FIG. 2 d, when water is injected below the water level line in FIG. E, the water in the cup is not drained 12 from the drain H, and if the water is injected above the water level line 8, Apparently, the situation in which almost all of the water is drained 12 from the drain outlet H is the same as the experimental result of the above item 1.
However, when water is poured again into FIG. F after draining in FIG. E, even if the amount of water 11 poured is small, as shown in FIG. It ends up.

Therefore, FIG. 3 shows an enlarged cross-sectional view of the main part of the cup 1 in the situation of FIG. 2g. As can be seen from a glance at FIG. 3, the stagnant water 15 and the stagnant water 14 stay in the intake pipe 6 and the drain pipe 4 so as to stick to each other. Using the G = S type as the intake S of the intake pipe 6, that is, when observing the situation after draining using the intake pipe 6 processed with a low notch gap G, the atmospheric pressure of the water surface at the intake S is It is determined that the weight of water in the intake pipe 6 matches the weight of ST and TH in FIG. 3 and the water remains in both pipes as shown in FIG. At this time, it is confirmed that the surface tension ST acts on the drainage port H and the intake port S, and water polo is formed on the drainage port H.
Therefore, when water is poured into the cup 1 from the state of FIG. 3, the atmospheric pressure at the water surface of the water intake S is increased, and the stagnant water in both pipes is sequentially pushed out each time the water is poured 11 as shown in FIG. It seems that it is drained over. That is, although the situation is different from the above item 1, the phenomenon is also a siphon itself. By replacing the intake pipe 6 in this siphon cup, two different interesting siphons described in the above items 1 and 2 can be tested. .

3. FIGS. 2h to j show the siphon experimental situation when the G = 0 type (no-cut type) of the intake pipe 6 is set in the siphon cup. As shown in FIG. 2h, when the G = 0 type that does not process the water intake S is set in the water intake pipe 6 and water is injected as shown in FIG. I, the water in the cup is discharged from the water outlet H when water is injected below the water level line. There is no drainage 12 at all.
When water is poured into the water level line 8 or higher, the water in the cup gradually drops into water droplets and drops from the drain outlet H. However, in this case, as shown in FIG. J, when the knob portion 7 of the intake pipe 6 is picked and moved up and down or left and right, that is, moved so that a gap is formed at the lower end of the intake pipe 6, it becomes active every time. Good well drained. Of course, it is also a type of siphon.
<Experiment 2>

Now, regarding the method of performing the experiment 2 in the first embodiment, that is, the third siphon experiment using the siphon cup will be briefly described with reference to FIG. The experimental situation is as illustrated with FIG. That is, as shown in FIG. B, the cup 1 of FIG. 4a is pre-filled with water 11 until it overflows from the upper end T without the drain pipe 4, and the intake pipes 6 of FIGS. An interesting siphon experiment can be performed on the experiment to ask what happens to the water in the cup when it is set to drop into the cup 1 already filled with water, and only the result will be described below.
1. When the G = L-type intake pipe 6 is set as shown in FIG. 4c, almost all of the water in the cup is drained 12 each time.
2. When the G = S-type intake pipe 6 is set as shown in FIG. 4d, almost all the water in the cup is drained 12 in appearance. However, like the situation illustrated in FIG. 3, the accumulated water 14 and 15 remains in the drain pipe 4 and the intake pipe 6 as shown in FIG. 4E, which is different from the G = L type result.

On the other hand, instead of pouring water, another weight having a weight equivalent to the amount of water (approximately 50 g) may be put into the DC, and the weight may be simply fixedly attached instead of the DC.

A fifth embodiment of the siphon cup according to the present invention will be described.
FIG. 8 shows an embodiment in which the cup 1 in the siphon cup of the present invention is also used as a grip handle for a massager, and a massager is constructed using a golf ball as shown in FIG.
That is, in the fifth embodiment, the siphon cup shown in each of the above embodiments is used, or when the golf ball is not used, a golf ball is set on the cup 1 as a massager, and the cup 1 is also used as a handle of the massager. It can be used as a high value-added idea goods with both functions in the formula. The present applicant previously invented a massage device using a golf ball and has already applied for a patent as Japanese Patent Application No. 2007-16093 (filed on Jan. 26, 2007). The container 40 has a structure partially similar to the golf ball holding method shown in the above-mentioned patent application.

FIG. 8a shows the components of the massage device according to the fifth embodiment in a vertical arrangement, and will be described below in conjunction with the drawings of FIGS. 8a to e. As shown in the figure, the cup 1 serving as a handle in this embodiment has recesses formed at four locations on the outer periphery of the cup 1 as a shape that fits the grip, and a drain pipe 4 having the same structure as that described with reference to FIG. It is erected. In the opening 2 of the cup 1, the innermost diameter d5 = φ45 and the inner diameter d4 = φ40 of the constricted portion at the bottom are set, and a golf ball 42 having a diameter of a recognized golf ball of approximately φ43 is inserted into the opening 2. The opening 2 is formed and processed so that the substantially upper half of the golf ball protrudes and the substantially lower half is held by the opening 2 of the cup 1 when assembled as shown in FIG.
Then, the golf ball 42 having dimples 43 on the surface thereof is a cylindrical slide provided with the d4 = φ40 portion of the opening 2 of the cup 1 and the lower part of the golf ball at the upper end of the intake pipe 6 as shown in the sectional view of FIG. When the shaft is supported by the contact bearing edge 45 and assembled as shown in FIG. B, the golf ball is smoothly rotated.

8a will be further described with respect to the fifth embodiment. In the fifth embodiment, the upper end of the closed end 6t of the intake pipe 6 has the shape shown in FIG. This is a configuration example in which the sliding contact bearing edge 45 of the golf ball 42 is used. On the other hand, with the intake pipe 6 removed, the upper end T of the drain pipe 4 is directly pivotally supported by the golf ball, or the narrowed inner diameter d4 is reduced to, for example, φ30 position to rotate the golf ball. A bearing may be configured.
