Abstract

Provided according to an aspect of the invention may be an apparatus for manufacturing cosmetic, which includes a housing which forms an outer appearance; an internal phase container which is provided in the housing, and which stores internal phase fluid excluding surfactant; an external phase container which is provided in the housing, and which stores external phase fluid excluding surfactant; a channel unit which generates emulsion by mixing the internal phase fluid provided from the internal phase container and the external fluid provided from the external phase container; and an operative unit which provides external force required to form and discharge emulsion at the channel unit by manipulation of a user.

First claim

What is claimed is:

1. An apparatus for manufacturing cosmetic, the apparatus comprising:
a housing which forms an outer appearance;
an internal phase container which is provided in the housing, and which stores internal phase fluid excluding surfactant;
an external phase container which is provided in the housing, and which stores external phase fluid excluding surfactant;
a channel unit which generates emulsion by mixing the internal phase fluid provided from the internal phase container and the external phase fluid provided from the external phase container; and
an operative unit which provides external force required to form and discharge emulsion at the channel unit by manipulation of a user,
wherein by operation of the operative unit, more amount of the external phase fluid is supplied to the channel unit than the internal phase fluid, and
wherein the channel unit includes:
an internal phase fluid injection hole to which the internal phase fluid is provided from the internal phase container;
an external phase fluid injection hole to which the external phase fluid is provided from the external phase container;
a confluence part in which the internal phase fluid provided from the internal phase fluid injection hole and the external phase fluid provided from the external phase fluid injection hole are mixed with each other; and
a mixing section including a plurality of mixing parts which extend from the confluence part, and which generate emulsion particles by converting proceeding direction of fluid and thus forming vortices in flow.

2. The apparatus for manufacturing cosmetic of claim 1 , wherein the respective internal phase container and the external phase container are provided one or more in number, and the channel unit is provided with introducing parts to which fluids from the internal phase container and the external phase container flow, and
wherein the fluids which have flown to the introducing parts are guided to the confluence part to be mixed with each other.

3. The apparatus for manufacturing cosmetic of claim 1 , wherein by one-time operation of the operative unit, total discharging amount of the external phase fluid discharged from the external phase container is greater than total discharging amount of the internal phase fluid discharged from the internal phase container.

4. The apparatus for manufacturing cosmetic of claim 1 , the apparatus further comprising:
a functional container which is provided in the housing, and which stores functional fluid,
wherein the channel unit includes a functional fluid injection hole to which the functional fluid is introduced from the functional container, and the functional fluid which has flown to the functional fluid injection hole is guided to the confluence part to be mixed with the internal phase fluid and the external phase fluid.

5. The apparatus for manufacturing cosmetic of claim 1 , wherein the plurality of mixing parts is disposed around the confluence part with the confluence part as a center.

6. The apparatus for manufacturing cosmetic of claim 1 , wherein the channel unit is formed in one or more plates, and the confluence part and the mixing section are provided in a continuous single layer path.

7. The apparatus for manufacturing cosmetic of claim 1 , wherein the channel unit is formed in the plate of a single planar panel shape, and the confluence part and the mixing section are located on same planar surface in the plate.

8. The apparatus for manufacturing cosmetic of claim 1 , wherein the mixing part includes:
a first turning path which guides an entering fluid to be rotated in one direction;
a second turning path which guides the fluid rotating in one direction to be rotated in another direction; and
a direction converting path which changes a rotational direction of fluid between the first turning path and the second turning path.

9. The apparatus for manufacturing cosmetic of claim 8 , wherein the mixing part further includes a vortex prompting path for prompting formation of vortices at upstream of the first turning path or downstream of the second turning path.

10. The apparatus for manufacturing cosmetic of claim 1 , wherein the mixing part is provided three or more in number.

11. The apparatus for manufacturing cosmetic of claim 1 , wherein the mixing section includes:
a first mixing part which is connected to the confluence part;
a third mixing part which is located opposite to the first mixing part with respect to the confluence part; and
a second mixing part which is located between the first mixing part and the third mixing part.

12. The apparatus for manufacturing cosmetic of claim 11 , wherein the mixing section includes a fourth mixing part and a fifth mixing part which are located opposite to the second mixing part with respect to an imaginary straight line passing through the first mixing part, the third mixing part and the confluence part.

13. The apparatus for manufacturing cosmetic of claim 1 , wherein the channel unit further includes a particle size adjusting part which reduces size of the emulsion particle included in fluid provided from the mixing section.

14. The apparatus for manufacturing cosmetic of claim 13 , wherein the particle size adjusting part includes a convergence maintaining portion which has a width less than that of the mixing flow path of the mixing section.

15. The apparatus for manufacturing cosmetic of claim 14 , wherein the particle size adjusting part includes a divergence maintaining portion which is disposed at a rear end of the convergence maintaining portion, and which has a width greater than that of the mixing flow path of the mixing section.

16. The apparatus for manufacturing cosmetic of claim 1 , wherein the discharging part which discharges the emulsion is directly connected to a discharging hole formed in the channel unit.
