Abstract

To provide an emulsion preparation device capable of forming an emulsion in a chemical liquid of diverse composition and further realizing a relatively low sliding resistance. An emulsion preparation device ( 1 ) provided with a filter part ( 10 ), wherein: the filter part ( 10 ) is constructed from first and second, two mesh parts ( 31 ) and ( 33 ) and fibers ( 32 ); and the fibers ( 32 ) are loaded into a space ( 30 ) between the first mesh part ( 31 ) and the second mesh part ( 32 ).

First claim

The invention claimed is:

1. An emulsion preparation device comprising:
a filter part, the filter part including:
a first mesh part;
a second mesh part; and
fibers, the fibers being located in a space between the first mesh part and the second mesh part so as to constitute a fiber aggregate;

wherein at least one of the first mesh part and the second mesh part is a disk; and
wherein the disk of the at least one of the first mesh part and the second mesh part includes a plurality of through holes each having an arc shape, all of the through holes in the disk being uniformly arranged in a concentric manner and having the same area within an error range of 10%.

2. The emulsion preparation device according to claim 1 , wherein:
one side or both sides of the filter part is configured to be connected to a syringe; and
the filter part is configured such that an emulsion is formed when a continuous phase and a dispersed phase perform, through the filter part, reciprocating movement (i) between two syringes linked to the both sides of the filter part; or (ii) between a syringe linked to one side and a vessel linked to the other side.

3. The emulsion preparation device according to claim 1 , wherein the fibers are hydrophobic.

4. The emulsion preparation device according to claim 3 , wherein the hydrophobic fibers are polyester.

5. The emulsion preparation device according to claim 1 , wherein the fibers are hydrophilic.

6. The emulsion preparation device according to claim 1 , wherein the fibers have 50 deniers to 150 deniers and are loaded such that 2.5 mm to 17.7 mm are present per 1 mm 3 of the space.

7. The emulsion preparation device according to claim 1 , wherein the fibers have 50 deniers to 150 deniers and are loaded such that 5.0 mm to 9.9 mm are present per 1 mm 3 of the space.

8. The emulsion preparation device according to claim 1 , further comprising:
a first cylindrical member and a second cylindrical member;
wherein the first cylindrical member comprises a first cylinder part and a second cylinder part continuous to the first cylinder part;
wherein the second cylinder part has a smaller diameter than the first cylinder part;
wherein, in the first cylindrical member, the first mesh part is formed at a boundary between the first cylinder part and the second cylinder part, the fibers being pushed toward the first mesh part, the second mesh part being pushed against the fibers so as to form the filter part from the first mesh part, a fiber aggregate formed of the fibers, and the second mesh part;
wherein the second mesh part is a bottom face of a concave lid fit onto the first cylinder part;
wherein, in the concave lid, an outer flange in an aperture periphery abuts against an aperture periphery of the first cylinder part so that the second mesh part is positioned in the inside of the first cylinder part at a predetermined distance to the first mesh part and in parallel thereto; and
wherein the first cylindrical member and the second cylindrical member are joined into a single piece by the outer flange in the aperture periphery of the first cylinder part and an outer flange in an aperture periphery of the second cylindrical member.

9. The emulsion preparation device according to claim 1 , further comprising:
a first cylindrical member and a second cylindrical member;
wherein the first cylindrical member comprises a first cylinder part and a second cylinder part continuous to the first cylinder part;
wherein the second cylinder part has a smaller diameter than the first cylinder part;
wherein, in the first cylindrical member, the first mesh part is formed at a boundary between the first cylinder part and the second cylinder part, the fibers being pushed toward the first mesh part, the second mesh part being pushed against the fibers so as to form the filter part from the first mesh part, a fiber aggregate of the fibers, and the second mesh part;
wherein the second mesh part is a bottom face of a concave lid fit onto the first cylinder part;
wherein, in the concave lid, an outer flange in an aperture periphery abuts against an aperture periphery of the first cylinder part so that the second mesh part is positioned in the inside of the first cylinder part at a predetermined distance to the first mesh part and in parallel thereto;
wherein the first cylindrical member and the second cylindrical member are joined into a single piece by the outer flange in the aperture periphery of the first cylinder part and an outer flange in an aperture periphery of the second cylindrical member;
wherein the fiber aggregate is located in a center of a longitudinal direction of the emulsion preparation device; and
wherein, in a state that the first cylindrical member and the second cylindrical member have been joined into a single piece, an external shape is bilaterally symmetric in the longitudinal direction.

10. An emulsion preparation method employing the emulsion preparation device according to claim 1 .
