Abstract

PURPOSE:A cylindrical vessel for a stick cosmetic is filled with a solid cosmetic composition and they are heated together to melt the composition, then cooled down to give the solid cosmetic without damage of the stick cosmetic with high resistance to breakage and good usability. CONSTITUTION:A cylindrical vessel 6 set to the opening 8 on the cut plate 2 is filled with a thermally meltable solid cosmetic composition 7 through opening 5 formed on the guide plate 4 of the cut plate 2. The cut plate 2 is allowed to slide toward the left side to close the opening 5 with the cut plate 2 and simultaneously, the cylinder 6 is pushed out of the vessel outlet 13 on the side of push plate 9. Then, an appropriate heater is used to heat the vessel and the cosmetic to melt the oil or wax in the cosmetic, then cooled down by left standing to give a stick cosmetic.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding bar-shaped cosmetics, such as lipsticks, eye shadows, etc.

A solid cosmetic composition such as a rod-shaped cosmetic such as an eyebrow cream is directly filled into a cylindrical container, and the filling material is heated and melted together with the cylindrical container, and then cooled. There is no rod-forming or breakage of the sugar during operation. ,
It also has high bending strength.

The purpose of the present invention is to provide a molding method for obtaining a rod-shaped cosmetic with excellent usability.

Conventionally, most of the cosmetic compositions applied to bar-shaped cosmetics such as lipsticks, eye shadows, foundations, and eyebrows have a high oil content, and the compositions are heated and melted to make them fluid. However, the bar-shaped cosmetics obtained in this way have low bending strength and are easily broken, so they must be made thicker. However, as a result of various experimental studies, the present inventors have obtained the present invention which does not have these drawbacks.

In the present invention, a solid cosmetic composition having heat-melting properties is filled into a cylindrical container removably attached to the cut plate through a filling hole formed in the guide plate of the cut plate using a filling nozzle, and then the cut plate is attached to the cylindrical container. Slide and close the filling hole with the cut plate.
In addition, a method for forming a bar-shaped cosmetic comprises filling a cylindrical container in the first stage through a container outlet provided on the side of a presser plate supporting the cylindrical container, heating and melting a nine-solid cosmetic composition, and then cooling it. It is.

The present invention will be explained below using an implementation device shown in the drawings. Figure 1 is a sectional view, Figure 2 is a sectional view taken along line A-A in Figure 1, and Figure 3 is a sectional view.
The figure is a cross-sectional view taken along the line B--B in FIG. 1, and FIG. 4 is a cross-sectional view showing the cut plate being slid.

First, oils are heated and melted in a vacuum disperser filled with 80 to 40% by weight of a known powdered cosmetic composition.

Add 20 to 60% by weight of oil such as wax, disperse while degassing, fill in a container, etc., and leave to cool at room temperature to form a heat-melting solid cosmetic composition. rear,
Fill the supply tank. The lower end of the filling nozzle 1 connected to the supply tank is opened in the filling hole 5 of the guide plate 4 in which the cut plate 2 is slidably housed in the sliding groove 3 on the lower surface, and communicates with the filling hole 5 to form a cylindrical container 6. A mounting hole 8 for removably attaching the upper part of the cylindrical container 6 is formed in the cut plate 2, a holding plate 9 is formed on the lower surfaces of the cut plate 2 and the guide plate 4, and an annular protrusion l is formed on the outer periphery of the upper part of the cylindrical container 6.
A groove 11 that locks the O.

A container outlet 13 is formed on the side surface of the insertion hole 120 into which the cylindrical container 6 is inserted in the holding plate 9, and a container outlet 13 is provided on the sides of the groove 11 and the insertion groove 12 to take out the cylindrical container 6 laterally. In the figure, 7 is a solid cosmetic composition, and 14 is an inner plate mounted at an appropriate position within the cylindrical container 6.

The present invention provides a heat-melting solid cosmetic in a cylindrical container 6 formed in a removable manner on a cut plate 2 through a filling nozzle 1 through a filling hole 5 formed in a cut plate 20 and a guide plate 4 using the above-described molding apparatus. After filling the composition 7, the cut plate 2 is first slid to the left in FIG. The container is taken out from the container outlet 13 to the side of the presser plate 9 and detached from the cut plate 2.

Next, the solid cosmetic composition in the cylindrical container 6 is heated by an appropriate heating device until the oils and waxes containing it are melted, and then cooled by air cooling or other appropriate cooling means.
It is possible to mold a rod-shaped cosmetic material by doing this. After removing the cylindrical container 6 filled with the solid cosmetic composition 7, a new empty cylindrical container is attached to the mounting hole 8 of the cut plate 2, and the cut plate 2 is attached.
The solid cosmetic composition 7 is then filled again.

In the present invention, a solid cosmetic composition 7 having heat-melting properties is filled from a filling nozzle 1 into a cylindrical container 6 removably formed on the cut plate 2 through a filling hole 5 formed in the guide plate 4 of the cut plate 2. Then slide the cut plate 2 in the first order to cut the filling hole 5 on the cut plate 2.
At the same time, the cylindrical container 6 is taken out from the container outlet 13 provided on the side surface of the presser plate 9 that supports the container.

Next, the solid cosmetic composition 7 filled in the cylindrical container 7 is heated and melted, and then cooled.
A solid cosmetic composition 7 such as a rod-shaped cosmetic such as an eye shadow, a foundation silane, or an eyebrow is directly filled into a cylindrical container 6, and the filling material is heated and melted together with the cylindrical container 6, and then cooled. This is a molding method that can produce bar-shaped cosmetics that do not break, have high bending strength, and are excellent in usability.
