Description

  The present invention relates to a multicolor solid cosmetic, and more particularly to a multicolor solid cosmetic having a gradation pattern.

  For cosmetics, in addition to their functions, giving beauty to cosmetics is important for making the cosmetic effect more effective. For example, coloring cosmetics in multiple colors brings a colorful and aesthetic beauty. Furthermore, providing a multicolored gradation pattern is one method for improving aesthetics.

  Many techniques for giving a gradation pattern to a multicolor solid cosmetic are disclosed, but many are powder-based, and a gradation pattern is imparted to a cosmetic containing an oil-based or water-based solid cosmetic composition. Only discloses a technique of a cosmetic product in which a container is filled with two types of cosmetic compositions and the surface of the cosmetic composition filled on the bottom side is formed on an inclined surface (see Patent Document 1). Furthermore, it is significant to develop a multicolor solid cosmetic having a gradation pattern with different tastes.

  It is not a cosmetic technology, but one of the two transparent transparent soap bases mixed with each other is poured into a mold and cooled, and then the cooled soap base is solidified. The other soap base heated and melted at a temperature higher than that of the cooled soap base is poured into the mold, and then cooled until the two types of molten transparent soap bases are solidified to have multiple colors. A technique for providing a transparent soap with a gradation pattern is disclosed (see Patent Document 2).

JP 2005-320268 A Japanese Patent No. 3405853

  This invention is made | formed in view of the said situation, The objective is to provide the multicolor solid cosmetics which have a gradation pattern.

  As a result of earnest research to solve the above problems, the present inventor has obtained a plurality of solid cosmetic compositions of different colors other than the top layer of the plurality of solid cosmetic compositions. By laminating in a vertical direction so that at least one upper surface of the solid cosmetic composition has a mortar-shaped concave surface and the solid cosmetic composition having the concave upper surface is transparent The present inventors have found that the above problems can be solved and have completed the present invention.

  That is, the first invention is a multicolor solid cosmetic in which a plurality of solid cosmetic compositions colored in mutually different colors are laminated without gaps in the vertical direction, and the plurality of solid cosmetics Of the composition, at least one upper surface of the solid cosmetic composition other than the uppermost layer is a surface having one or a plurality of mortar-shaped recesses, and the solid makeup having the upper surface of the recesses It is a multicolor solid cosmetic whose composition is transparent.

  Further, the second invention is a method of injecting a semi-molten or melted cosmetic composition, which is solidified transparently at room temperature after being heated and melted, into a semi-molten state, and then into the semi-molten state in the mold On the first cosmetic composition in a state, a semi-molten or melted cosmetic composition solidified at room temperature colored in a color different from the first cosmetic composition heated and melted, After discharging and filling one or several places on the upper surface of the first cosmetic composition in a molten state and laminating the two types of cosmetic compositions up and down, the two types of cosmetic compositions solidify. It is the said multicolor solid cosmetics manufactured including the process cooled to.

  In addition, the third invention is the first cosmetic composition in the molten state in the mold, after injecting into the mold in a molten state a cosmetic composition that is solidified by heating and melting at room temperature The upper surface of the molten first cosmetic composition in a semi-molten state, the cosmetic composition solidifying at room temperature colored in a color different from that of the first melted cosmetic composition. The above-mentioned many kinds of products are manufactured by including a step of discharging and filling in one to several places, laminating the two kinds of cosmetic compositions on the top and bottom, and cooling until the two kinds of cosmetic compositions are solidified. It is a color solid cosmetic.

  In the present invention, the “solid cosmetic product” refers to a product in which a solid cosmetic product is stored or mounted in a container. The “cosmetic composition” refers to a colored composition in a uniform state by combining cosmetic ingredients, and a multicolor cosmetic is formed by laminating the composition. Further, “lamination” means that one solid cosmetic is formed and the cosmetic composition is connected in a state where the cosmetic composition does not naturally separate into a plurality.

  The upper side of the solid cosmetic refers to the side on which the concave portion of one cosmetic composition constituting the solid cosmetic is formed.For example, in the production of a solid cosmetic, when the mold is filled with the cosmetic composition, The side into which the cosmetic composition is poured is the upper side. Therefore, the recess is formed on the upper surface of the cosmetic composition. There are various types of molding dies. For example, in the case of Ojive molding described later, a solid cosmetic directly stored in a container is obtained by molding. In this case, the side attached to the solid cosmetic container is the upper side, and the boundary surface of the cosmetic composition forms a convex portion toward the tip of the solid cosmetic. In addition, when molded using a split mold, the side into which the cosmetic composition is poured is the upper side, and the cosmetic composition has a concave portion on the upper surface, but the direction of the container mounting on the obtained solid cosmetic If there is not, when installing it in a container and manufacturing a solid cosmetics, the boundary surface of solid cosmetics can form a recessed part toward a use part side, and can also form a convex part.

  The “boundary part” is a boundary part of the cosmetic composition layer, and there are two cosmetic compositions in the layer cross section at the boundary part, and the ratio of one of the cosmetic compositions is 0. An area in the range exceeding 100% and less than 100%.

  Further, the term “transparent” refers to a transparent concept that includes translucency. The term “transparency” refers to a level at which a cosmetic composition in front of the front of the multicolor solid cosmetic can permeate through the front cosmetic composition and can be visually sensed. It should be noted that the transparency as a measure of transparency is measured by, for example, sensuously judging the characters, drawings and the like through a sample.

  In addition, liquid, solid, solid and the like all represent a state at normal temperature except for a description such as temperature. Moreover, solid is what has no fluidity at normal temperature, and such a state is called solid. That is, when the cosmetic composition is moved at room temperature, a state having a hardness that maintains the shape is referred to as a solid state. Moreover, solidifying means that what has fluidity | liquidity becomes solid state. The solid hardness is measured, for example, with a jelly strength meter by allowing a spherical or disk-shaped attachment to enter the specimen.

  Further, the melted state and the semi-molten state of the solid cosmetic composition are both fluid states, and when the two types of cosmetic compositions are in contact with each other, the two types of compositions are in contact with each other. Each of the natural blends is said to be in a molten state. Therefore, for example, when a blue melted cosmetic composition and a red melted cosmetic composition come into contact with each other, a natural purple-colored or blue-red marbled cosmetic composition is naturally formed.

  As the temperature of the cosmetic composition in the molten state is lowered, it becomes a semi-molten state. The cosmetic composition in the semi-molten state does not naturally mix with each other even when it comes into contact with other cosmetic compositions. Therefore, for example, when a semi-molten cosmetic composition and a semi-molten cosmetic composition are in contact with each other, the boundary portion does not naturally mix with each other and a clear boundary is formed. Two types of cosmetic compositions that do not naturally mix with each other form a boundary and a boundary portion.

  Semi-molten and melted states are adjusted by the temperature of the cosmetic composition. The temperature at which the semi-molten state changes to the molten state varies depending on the formulation of the cosmetic composition such as powder, gelling agent, thickener, solid oil, and the like. The temperature range in the semi-molten state is about 50 to 85 ° C.

  The multicolor solid cosmetic according to the present invention exhibits a beautiful multicolored appearance, and a beautiful gradation pattern can be seen when the multicolored boundary is viewed from various viewpoints.

  The present invention is a multicolor solid cosmetic in which a plurality of solid cosmetic compositions colored in mutually different colors are laminated without gaps in the vertical direction, and the plurality of solid cosmetic compositions Of these, at least one upper surface of the solid cosmetic composition other than the uppermost layer is a surface having one or a plurality of mortar-shaped recesses, and the solid cosmetic composition having the upper surface of the recesses Is a multicolor solid cosmetic that is transparent.

[About multicolor solid cosmetics]
In the multicolor solid cosmetic according to the present invention, a plurality of cosmetic compositions colored in different colors are laminated without any gaps in the vertical direction. The “different colors” may not be different for all the compositions, and the cosmetic compositions may include the same color as long as the adjacent compositions have different colors.

Furthermore, the multicolor solid cosmetic according to the present invention is characterized in that at least one upper surface of the solid cosmetic composition other than the uppermost layer among the plurality of solid cosmetic compositions has one or more mortars. The solid cosmetic composition having a surface having a concave shape and having the upper surface of the concave portion is transparent.

In the present invention, it is preferable that the solid cosmetic composition other than the solid cosmetic composition having a recess on the upper surface is transparent from the viewpoint that the gradation pattern can be seen more beautifully.
The plurality of cosmetic compositions colored in different colors are laminated without being mixed.

  The concave portion of the solid cosmetic composition may be a mortar-shaped concave portion that is formed on the surface and gradually becomes deeper toward the center of the surface, or a plurality of concave portions may be provided on the surface.

  In the present invention, by making the solid cosmetic composition having the upper surface of the recess transparent, a gradation pattern can be seen at the boundary of the cosmetic composition when viewed from the side of the multicolor solid cosmetic. . For example, at the boundary between a solid cosmetic composition having a concave portion on the upper surface colored blue and a solid transparent cosmetic composition colored red above it, it changes from blue to red via purple. You can see the gradation pattern. When the depth of the recess is deep, a wide gradation pattern can be seen. In addition, since one or a plurality of concave portions are formed on the surface, different gradation patterns can be seen. For example, if there are a plurality of recesses, the change in gradation color becomes complicated. Further, when the multicolor solid cosmetic is viewed from the lower surface, it exhibits a gradation pattern in which the color tone changes circumferentially. This pattern can be seen not only from the lower surface but also from the upper surface when the cosmetic composition in the upper layer portion is made transparent.

  In producing the multicolor solid cosmetic according to the present invention, it is not particularly limited. For example, a first cosmetic composition that is solidified transparently at room temperature by heating and melting is injected into a mold. Then, the second cosmetic composition solidified at room temperature which is heated and melted and colored in a color different from the first cosmetic composition is melted into the first cosmetic composition in the mold. After filling the upper surface of the object, it is manufactured by cooling. During the manufacturing process, a recess is formed on the upper surface of the first cosmetic composition due to the filling pressure of the cosmetic composition when the second cosmetic composition is filled.

  In the present invention, when the first and second cosmetic compositions that are solidified at room temperature that are heated and melted are both in a semi-molten state, they are expressed because there is no mixing at the boundary between the cosmetic compositions. The optical gradation pattern can be seen clearly. Further, when one of the first and second cosmetic compositions is in a molten state and the other is in a semi-molten state, the boundary surface layer portion of the cosmetic composition in a semi-molten state when the molten cosmetic composition is in a semi-molten state The cosmetic compositions are not naturally mixed with each other only by dissolving the water, the boundary line becomes slightly thicker, and the boundary surface layer portion is dissolved to increase the strength of the boundary portion. Multicolor solid cosmetics are stable and preferred. The higher the temperature of the molten cosmetic composition, the easier it is to mix. In addition, when two types of molten cosmetic compositions are in contact with each other, the cosmetic compositions naturally mix with each other, and a boundary cannot be formed.

  The filling method of the second cosmetic composition is preferably performed using a filling nozzle. As the filling nozzle, those commonly used for filling cosmetic compositions are used, and the nozzle diameter is preferably 1 to 5φ, and the smaller the nozzle diameter, the smaller the flow diameter of the cosmetic composition can be discharged and obtained. The recess is deep with a small hole diameter.

  Although the said filling pressure is not specifically limited, When filling with a filling nozzle, 2-10 g / s is preferable with a nozzle with a diameter of 2phi, and it is preferable to fill with the pressure equivalent to it also in another filling method. A deeper recess is formed as the filling pressure is increased. In addition, the depth of the recess depends on the viscosity at the time of filling the first cosmetic composition first filled in the mold, and the deeper the recess, the lower the viscosity.

  Further, if the second cosmetic composition is filled in one place on the upper surface of the first cosmetic composition, one recess is obtained, and if several places are formed, a plurality of recesses are formed. Further, when the filling is performed with the mold placed in an in-place state, the one having a horizontal boundary surface is obtained. In addition, when the container is filled in an inclined state, an inclined boundary surface can be obtained. The multicolor solid cosmetic having the inclined boundary surface exhibits a complicated gradation pattern.

  Hereinafter, the multicolor solid cosmetic of the present invention will be described in detail.

  The multicolor solid cosmetic is prepared by, for example, injecting a heat-melted cosmetic composition that solidifies transparently at room temperature into a mold in a semi-molten or molten state, and then into a semi-molten state. On the first cosmetic composition in the semi-molten state, the cosmetic composition solidified at room temperature colored in a color different from that of the first cosmetic composition heated and melted is in a semi-molten or molten state. The two kinds of cosmetic compositions are stacked by discharging and filling one to several places on the upper surface of the first semi-molten cosmetic composition, and then laminating the two kinds of cosmetic compositions. It is manufactured including a step of cooling until it solidifies.

That is, it is manufactured including the following steps.

Here, the semi-molten state of the first cosmetic composition is maintained, for example, by keeping the mold warm. Moreover, the temperature of the 1st cosmetic composition at the time of inject | pouring should just be the temperature which this cosmetic composition fully melt | dissolves thru | or melts, and is not specifically limited.
(3) Next, the second cosmetic composition solidified at room temperature colored in a color different from that of the first cosmetic composition heated and melted on the first cosmetic composition in the semi-molten state. In a semi-molten or molten state, the product is discharged and filled into one or several places on the upper surface of the semi-molten first cosmetic composition, and the first cosmetic composition, the second cosmetic composition, Lay things up and down.
(4) Next, the cosmetic composition laminated above and below is cooled and solidified in a mold.

  Further, the multicolor solid cosmetic is prepared by injecting a molten cosmetic composition that is solidified at room temperature into a mold in a molten state, and then in the molten first cosmetic in the mold. A first cosmetic composition in the molten state, in a semi-molten state, on a cosmetic composition, solidified at room temperature colored in a color different from that of the first cosmetic composition heated and melted It is manufactured by discharging and filling one or several places on the upper surface of a product, laminating the two types of cosmetic compositions on top and bottom, and then cooling until the two types of cosmetic compositions are solidified. The

That is, it is manufactured including the following steps.
(1) First, a first cosmetic composition that is solidified transparently at room temperature that is heated and melted is prepared.
(2) Next, the first cosmetic composition is poured into the mold in a molten state, and then maintained in the molten state. Here, holding | maintenance of the molten state of a 1st cosmetics composition is performed by heat-retaining a shaping | molding die, for example. Moreover, the temperature of the 1st cosmetics composition at the time of inject | pouring should just be the temperature which this cosmetics composition melt | dissolves sufficiently, and is not specifically limited.
(3) Next, a second cosmetic composition that solidifies at room temperature colored in a different color from the first cosmetic composition heated and melted on the first cosmetic composition in the molten state. In a semi-molten state, the first cosmetic composition and the second and cosmetic compositions are stacked one above the other in a semi-molten state by being discharged and filled in one or several places on the upper surface of the molten first cosmetic composition. To do.
(4) Next, the upper and lower laminated cosmetic compositions are cooled and solidified in a mold.

  The composition of the plurality of solid cosmetic compositions may be the same or different except for the colorant. Further, one kind of composition that is not colored may be prepared, divided into a plurality of parts, and different colorants may be added and colored to each.

  The method for cooling the melted or semi-melted cosmetic composition solidified at room temperature in the present invention is not particularly limited, and examples of the cooling medium include water cooling and air cooling, and the temperature range is −10 to 10 ° C. . Natural cooling may also be used. Moreover, the target temperature of the cooled cosmetic composition is 20-30.

  For example, the mold is generally a split mold in which a cavity (dent) corresponding to the shape of the solid cosmetic is formed, and the cavity is filled with the molten cosmetic composition, After the cosmetic composition is cooled and solidified to form a solid cosmetic, the solid cosmetic is removed from the mold and attached to a container to produce a solid cosmetic.

  The rubber mold is generally a container-like rubber mold corresponding to the shape of the solid cosmetic, and the mold is filled with a molten cosmetic composition, and then the cosmetic After the material composition is cooled and solidified to form a solid cosmetic, the rubber mold is deformed to remove the solid cosmetic from the rubber mold, and this is attached to a container to produce a solid cosmetic.

  In addition, Ojib is a removable type assembled in a container, and generally has a sheath shape. As a material of Ojib, for example, resins such as polystyrene resin, polypropylene resin, and silicone resin are generally used. As a method for producing solid cosmetics and solid cosmetics using Ojib, Ojib (for example, sheath-shaped Ojib) is assembled in a container (for example, a pay-out type container), and this is placed in an inverted position to be in a molten state. The cosmetic composition is filled into the Ojive from the bottom of the container. Next, the cosmetic composition filled in Ojib is cooled and solidified to form a solid cosmetic, and then Ozibe is removed to produce a solid cosmetic attached to the container.

  Further, some molds also serve as a payout container, and this is also included in the mold of the present invention. In this product, a container is used as a mold, and a product molded by the container is used as it is.

  In the method for producing a multicolor solid cosmetic according to the present invention, the solid cosmetic composition is not limited to two types as long as it includes the above-described steps. These cosmetic compositions may be combined. For example, among the three types of solid cosmetic compositions, after filling the first solid cosmetic composition and the second solid cosmetic composition into the mold by any one of the production methods, Furthermore, the third solid cosmetic composition can be filled on the second solid cosmetic composition to produce a three-layer multicolor solid cosmetic. If the third solid cosmetic composition is filled in the same manner as the method of laminating the two kinds of solid cosmetic compositions, all the boundary portions of each layer have a gradation pattern. Multicolor solid cosmetics are manufactured.
