BEST MODE FOR CARRYING OUT THE INVENTION

[0083] Described hereinafter with reference to the attached drawings are detailed embodiments of the device and method according to the present invention. In the figures, like reference numerals refer to like members which have similar basic composition and operation.

First Embodiment

<Configuration>

[0084] FIG. 1 is a perspective view showing the outlook of a device for mixing liquid material 1 according to the present invention. It has a container 10 which contains liquid material. It is desirably made of transparent or opaque material so as to make visible the status of the content, be it mixed, precipitated or dispersed. The container 10 is also desirably capable of self-standing.

[0085] Although the container 10 is depicted in a cylindrical shape is shown in FIG. 1, it may be in any other shapes.

[0086] The container 10 is equipped with an opening-closing member 11 coupled to its top, through which the liquid material is let in and out. In the present embodiment, the opening-closing member 10 is made of a screw cap. It is desirable that the screw cap seals the top of the container 10 tight enough that the content does not leak even when the device is shaken by hand. The screw cap can be replaced with a fitting cap or any other types of caps as long as it seals the top of the container 10 tight enough.

[0087] FIG. 1 shows the device for mixing liquid material 1 with the opening-closing member 11 being fastened. Accommodated in the container 10 is a coil spring 20. The coil spring 20 has its upper end fixed on the container 10 and its lower part unfixed, vibrable and oscillable. The coil spring 20 may be made of iron, steel, stainless steel, titanium, titanium alloy or plastics. The wire of the coil spring 20 may have roughened surfaces.

[0088] As shown in FIG. 1, the coil spring 20 has a perimeter smaller than that of the container 10. This allows the coil spring 20 to vibrate and oscillate when the device 1 is shaken by a user's hand. Then term “oscillate” or “oscillable” herein describes the coil spring 20 oscillating in its extending and shrinking direction and the term “vibrate” or “vibrable” herein describes the coil spring 20 vibrating in directions different from its extending and shrinking direction.

[0089] The coil spring 20 desirably has a length of 60 to 80% of the inner longitudinal length of the container 10. A coil spring shorter than this does not effectively stir the content, and a coil spring longer than this does not have enough flexibility of vibration and oscillation.

[0090] The coil spring 20 vibrates and oscillates to shear the liquid material. If the coil spring 20 has roughened surfaces, it has higher shearing effect. The shearing effect of the coil spring 20 effectively allows the liquid material to be evenly mixed and dispersed.

[0091] FIG. 2 is an axial cross section view of the device for mixing liquid material 1. The upper part of the container 10 and the inner wall of the opening-closing member 11, or the screw cap, are threaded. The container 10 accommodates in its upper part an internal lid 12. The internal lid 12 fixes thereon the upper end of the coil spring 20.

[0092] It is desirable that the internal lid 12 and the coil spring 20 are disassemblable from the container 10 so as to be easily cleaned. It is also desirable that the opening-closing member 11 can be fastened on the container tight enough so as to firmly fix the internal lid 12 and the upper end of the coil spring 20 on the container 10.

[0093] It is also desirable that the internal lid 12 has a large opening on its center, and the inner perimeter of the opening is tapered so as to ease letting out the liquid material.

[0094] FIG. 3 shows an exploded view of the device for mixing liquid material 1. As shown in FIG. 3, the internal lid 12 has a large opening on its center such that the liquid material can be easily let in and out therethrough. The internal lid 12 has the tapered inner perimeter such that the liquid material can be smoothly let in and out therethrough.

[0095] The internal lid 12 is configured such that the coil spring 20 can be mounted thereon. The uppermost part of the wire of the coil spring 20 is bent so as to be mounted on the internal lid 12.

[0096] As shown in FIG. 3, the coil spring 20 is mounted on the internal lid 12, and accommodated in the container 10, and then the internal lid 12 is fixed on the upper part of the container 10. Then, the opening-closing member 11 is fastened on the container 10. In this way, the device for mixing liquid material 1 is assembled.

[0097] The container 10 is equipped with a packing between its top and the opening-closing member 11 so as to improve the sealability of the device 1.

<Dispersing Vegetable Oil in Water>

[0098] FIG. 4 includes a view (4(a)) showing the device for mixing liquid material 1 in the state that it contains liquid material, and a view (4(b)) showing the device for mixing liquid material 1 in the state it contains liquid material and has the opening-closing member 11 and the coil spring 20 fastened thereon.

[0099] The container 10 is made of a transparent bottle with 500 ml capacity. As shown in FIG. 4, the container 10 contains 300 ml of water and 25 ml of vegetable oil, and the oil phase is separated from and above the aqueous phase.

[0100] The extent of strength with which a user shakes the device is classified into levels 1 to 4. Higher level indicates higher extent of strength.

[0101] FIG. 5 includes a view (5(a)) showing the device for mixing liquid material 1 in the state that it is shaken with level 1 strength with the coil spring 20 fixed thereon, and a view (5(b)) showing the device for mixing liquid material 1 in the state that it is shaken with level 1 strength without the coil spring 20.

[0102] When the coil spring 20 is present, the elastic energy of the coil spring 20 causes the oil phase to be micronized. It is observed that some of the oil has been micronized into oil drops and dispersed in the aqueous phase.

[0103] When the coil spring 20 is not present, the oil phase is not micronized.

[0104] FIG. 6 includes a view (6(a)) showing the device for mixing liquid material 1 in the state that it is shaken with level 2 strength with the coil spring 20 fixed thereon, and a view (6(b)) showing the device for mixing liquid material 1 in the state that it is shaken with level 2 strength without the coil spring 20.

[0105] When the coil spring 20 is present, the elastic energy of the coil spring 20 causes the oil phase to be micronized and scattered. It is observed that most of the oil has been scattered in the aqueous phase and some of the oil has been micronized into oil drops and dispersed in the aqueous phase.

[0106] When the coil spring 20 is not present, some of the oil has been scattered in the aqueous phase.

[0107] FIG. 7 includes a view (7(a)) showing the device for mixing liquid material 1 in the state that it is shaken with level 3 strength with the coil spring 20 fixed thereon, and a view (7(b)) showing the device for mixing liquid material 1 in the state that it is shaken with level 3 strength without the coil spring 20.

[0108] When the coil spring 20 is present, the elastic energy of the coil spring 20 causes the oil phase to be micronized and scattered. It is observed that most of the oil has been micronized into oil drops, evenly scattered, and evenly dispersed in the aqueous phase.

[0109] When the coil spring 20 is not present, some of the oil has been scattered in the aqueous phase and others dispersed in the aqueous phase.

[0110] FIG. 8 includes a view (8(a)) showing the device for mixing liquid material 1 in the state that it is shaken with level 4 strength with the coil spring 20 fixed thereon, and a view (8(b)) showing the device for mixing liquid material 1 in the state that it is shaken with level 4 strength without the coil spring 20.

[0111] When the coil spring 20 is present, the elastic energy of the coil spring 20 causes the oil phase to be super-micronized and scattered. It is observed that almost all of the oil has been super-micronized into tiny oil drops, evenly scattered, and evenly dispersed in the aqueous phase, and turned into a yellow white mixture.

[0112] When the coil spring 20 is not present, some of the oil has been scattered in the aqueous phase and others dispersed in the aqueous phase.

[0113] FIG. 9 includes a view (9(a)) showing the device for mixing liquid material 1 in the state that it has been left standing for one hour after being shaken with level 4 strength with the coil spring 20 fixed thereon, and a view (9(b)) showing the device for mixing liquid material 1 in the state that it has been left standing for one hour after being shaken with level 4 strength without the coil spring 20.

[0114] When the coil spring 20 is present, it is observed that the aqueous phase has high transparency as the oil phase is still super-micronized and well dispersed.

[0115] When the coil spring 20 is not present, it is observed that the aqueous phase has low transparency as the oil phase is not well micronized nor dispersed.

[0116] The coil spring 20 is vibrated and oscillated by its restoring force. Deformation of the coil spring 20 causes it to discharge the accumulated elastic energy and to do mechanical work. It is confirmed that the coil spring 20 oscillating in its extending and shrinking direction at its eigenfrequency causes oil in water to be super-micronized.

<Experiment Using Coil Spring with Various Coil Pitch>

[0117] FIG. 10 is includes five views showing examples of coil springs A, B, C, D and E each having different coil pitch. The five springs each has a length of 11 cm (110 mm) and has its one end fixed on the internal lid of the container, although the container, the opening-closing member and the internal lid are not shown in the figure.

The bottom of the coil spring is fixed.

[0124] FIG. 11 shows a table of the experimental results on the stirring effects of the stirring devices having the coil springs A, B, C, D and E.

[0125] When the stirring devices were shaken by hand, the coil spring D vibrated the most intensively, followed by the coil springs B, A, C and E.

[0126] As shown in the table of FIG. 11, we observed the states of the stirring devices 5 minutes after being shaken 20 times, 15 minutes after being shaken 50 times, 20 minutes after being shaken 80 times, 25 minutes after being shaken 100 times, and 30 minutes after being shaken 130 times.

[0127] In the table of FIG. 11, the double circle mark means that the content of the stirring devices was thoroughly dispersed, the circle mark means that the content of the stirring devices was sufficiently dispersed, the triangle mark means that the content of the stirring devices was insufficiently dispersed, and the X mark means that the content of the stirring devices was hardly dispersed.

[0128] It was observed that the stirring device having the coil spring D demonstrated the highest dispersion performance, followed by the stirring devices having the coil springs A, B, C and E.

[0129] FIG. 12 is a view showing another example of the device for mixing liquid material according to the present invention. As shown in FIG. 12, the device for mixing liquid material 1 comprises an opening-closing member 31 to be coupled to the bottom of the container 10 in addition to the opening-closing member 11. The opening-closing member 10 can be made of a screw cap. It is desirable that the opening-closing member 10 has a flat bottom such that the container 10 is capable of self-standing. The container 10 is equipped with a packing between its bottom and the opening-closing member 31 so as to improve the sealability of the device 1.

[0130] It is further desirable that both the opening-closing members 11 and 31 have flat bottoms such that the container 10 is capable of self-standing even it is turned upside-down.

[0180] It is observed that the content agitated using the device with a coil spring remains to be well dispersed for 3 days.

<Mechanism of Action>

[0181] Described below are the mechanisms of action of the device for mixing liquid material according to the present invention.

[0182] One mechanism of action is that the vibration and oscillation of the coil spring agitates liquid material such that clusters of oil, particles and precipitations are sheared into a dispersed state.

[0183] Another mechanism of action is overtone resonance (scaling resonance). The vibration and oscillation of the coil spring does not only agitate liquid material but also produces sound, which may or may not be in audible frequency. Such sound is continuously produced during the time that the device is being shaken. Clash of clusters of oil, particles and precipitations also produce sound. The sound produced by the vibration and oscillation of the coil spring and the sound produced by the clash of clusters of oil, particles and precipitations are considered to be in harmonic relationship as the over tone of the former (higher harmonics) resonates the latter (scaling resonance). This promotes dispersion of oil, particles and precipitations.

[0184] Scaling resonance is a phenomenon that higher harmonics or overtone, which is tens of octaves higher, causes resonance. (Yoichi Fukagawa (1999), Protein Music, Tokyo, Chikuma-shobo.)

[0185] Resonance and sympathizing are distinguished herein. Whereas sympathizing occurs when vibration or oscillation is transmitted via solid, resonance occurs when vibration or oscillation is transmitted via fluid such as water and gas.

[0186] In the device for mixing liquid material according to the present invention, it is considered that the vibration and oscillation of the coil spring is transmitted to oil, particles and precipitations via fluid (liquid material) and thus overtone resonance (scaling resonance) occurs when the device is being shaken.

[0187] In the device for mixing liquid material according to the present invention, liquid material, viewed from a macro-viewpoint, imparts impact to the coil spring and causes it to be vibrated and oscillated.
