Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a filling and solidifying method for filling and solidifying an oil-based powder cosmetic into a container.

(Prior Art) Oil-based powder cosmetics consisting of a blend of oil and powder are filled using different filling methods depending on the amount of oil to be blended.

For example, in the case of a cake-type product with a low oil content of 20% or less, the powder is mixed with oil, fragrance, etc., and then crushed, filled into a container, and press-molded to solidify.

In addition, for oil-based products with a high oil content of 50% or more, add the mixed and pulverized powder to the heated and molten oil.
It is poured into a container in a molten state and allowed to cool and solidify.

For products with an oil content between the cake type and the oily type, press molding is difficult, and even when heated and melted, there is little fluidity, so it is difficult to pour, and even if poured, it will not flow all the way to the edge of the container. I couldn't do it,
Alternatively, the surface may bulge, which may detract from the appearance of the product. Therefore, the present applicant has previously proposed a method in which heated and molten cosmetics are poured into a cylindrical container, the solidified cosmetics are taken out, cut into appropriate thicknesses, filled into containers, and then pressed at low pressure.

(Problem 7α to be solved by the invention) As mentioned above, in conventional oil-based powder cosmetics, the filling and solidification method differs depending on the amount of oil blended, so the filling and solidification work is troublesome and the properties of oil-based powder cosmetics are poor. There was a problem in that equipment had to be prepared separately for each case, which increased equipment costs.

This invention provides a method for filling and solidifying oil-based powder cosmetics ranging from oil-based cosmetics with a relatively large amount of powder, with an oil content of approximately 20 to 80%, into containers using a single method. This is what I am trying to do.

(Measures Pi for Solving the Problems) In order to solve the above problems, the means taken by this invention is to heat an oil-based powder cosmetic whose main components are oil and powder to make it fluid. After that, it is injected under pressure into a container whose open side is closed with a lid while pushing out the air, and after being injected, it is cooled and solidified.

(Function) Oil-based powder cosmetics that have been heated and turned into a slurry are filled into a container under pressure, and the air inside the container is pushed out to the outside as it is filled. It can be filled with powdered cosmetics.

(Embodiments) Preferred embodiments of the present invention will be described below with reference to the drawings. The method of the present invention includes providing a filling port approximately in the center of the closed surface of the container, and opening an air vent hole at a distance from the filling port.
The container is characterized by filling the open surface of the container with a heated and molten oil-based powder cosmetic under pressure from the filling port.

Referring to FIG. 1, (1) is a heating hopper, (2) is a filling nozzle continuous to the hopper (1), and pressurizing means is provided between the hopper (1) and the filling nozzle (2). (3) is arranged, and the oil-based powder cosmetic (4), which is melted and slurried by heating in the heating hopper (1), is pressurized by the pressurizing means (3) and passed through the filling nozzle (2) into the container ( 5) Fill.

The container (5) is, for example, a dish-shaped container called a so-called middle tray that is stored in a compact, and has a filling port (6) formed in the center of the bottom, which is a closed surface, and an air vent hole (7) in the side surface.
is perforated. The size of the air vent hole (7) is sufficient for air to escape, but due to its viscosity, the press-fitted cosmetic (4) blocks the hole (7) and cannot flow out of the inner tray (5). The size should be small enough.

When filling, as shown in the first diagram, cover the open surface of the inner tray (5) with a lid (8) made of metal or synthetic resin, and align the filling nozzle (2) with the filling opening (6). The oil-based powder cosmetic (4) that has been made into a slurry is injected under pressure. Due to the pressure, the cosmetic (4) is filled while pushing out the air in the inner tray (5) through the air vent hole (7). (9 ) is a release sheet coated on the open surface of the container (5) as required, and is made of paper, cloth, etc., and is used to apply a desired horizontal pattern to the surface of the filled cosmetic (4), and , to prevent leakage of the cosmetic (4) during filling.

After filling, cool the cosmetics (4) by blowing cold air (10) on them.
) is solidified (Figure 1L). Thereafter, the lid (8) is removed (Fig. 1 ρ-), and the release sheet (9) is peeled off and removed (Fig. 1 D).

The positions of the filling port (6) and the air vent hole (7) are not limited to those shown in FIG. 1 above. Figure 2.3 shows the modification, in which a filling port (6) is formed in the center of the bottom and air vent holes (7) are formed in the four corners of the bottom, and in Figure 3 A filling port (6) is formed in the center of the negative side, and an air vent hole (7) is formed in the other side facing the negative side. In the container shown in Figure 1.2, the container (5) can be filled with cosmetics in a vertical direction;
The container shown in FIG. 3 can also be filled horizontally.

Next, the ingredients and amounts of the oil-based powder cosmetic filled by the method of the present invention will be shown. The ingredients of an oil-based powder cosmetic are mainly oil and powder, and solid oil, perfume, antioxidant, surfactant, etc. are appropriately added thereto.

Oils include vegetable oils, animal oils, mineral oils, synthetic ester oils, and synthetic silicone oils commonly used in cosmetics. Examples of these include, for example, olive oil, jojoba oil, castor oil, phosphorus and its derivatives, slurrylan, liquid paraffin, petrolatum, trimethylolpropane triisostearate, isopropyl myristate, glycerol tri2-ethylhexanoate, penta Examples include erythritol tetra-2-ethylhexanoate, polyphenylmethylsiloxane, lamate, and silicone oil.

Powders are powders that are generally used in cosmetics, such as extender pigments such as talc, mica, clay, kaolin, and pearlescent agents; inorganic pigments such as titanium oxide, zinc white, iron oxide, and ultramarine;
and organic pigments.

The solid oil has a melting point of 40°C or higher, and one or more of various glycerides including higher alcohols, higher fatty acids, hydrocarbons, and natural waxes with a melting point of 40°C or higher are optionally added. selected and used. Examples of these solid oils include cetyl alcohol stearic acid, behenic acid, solid paraffin, microcrystalline wax, polyethylene powder, candelilla wax, peace wax, carnavalois barico wax,
Mention may be made of hydrogenated castor oil.

[1] When the oil-based powder cosmetics of Examples 1 to 5 were filled into containers using the method of the present invention, they were successfully filled and solidified without creating any voids up to the edges of the container, and there was no inconvenience that the surface would bulge. It did not occur.

By the method of this invention, it was possible to fill and solidify an oil-based powder cosmetic with a composition ranging from 20 to 80% oil without any problems.

(Effects of the Invention) According to the method for filling and solidifying an oil-based powder cosmetic of the present invention, the oil-based powder cosmetic whose main components are oil and powder is heated to form a slurry, and then the open surface is closed with a lid. The method is injected into the container under pressure while pushing air out to the outside, and then cooled and solidified after being poured. Therefore, it is possible to fill the container with oil-based powder cosmetics with a composition range of 20 to 80% oil and solidify them, unlike conventional methods. Since there is no need to change the filling method or equipment depending on the blending ratio of oil, it is possible to fill and solidify oil-based powder cosmetics extremely efficiently and at low cost.
