Description

  The present invention relates to a method for producing tablet-type powders or injectable cosmetics.

  Processes for producing colored tablet cosmetics in powder or injected form are known.

  In general, there are two systems for producing multicolored powder cosmetics, also called godets, contained in the same container.

  One involves dispensing a separate colored powder into each of the laterally adjacent cavities of a metal cylinder with a separating partition. The powder is injected into the cavities by a screw and is pressed in the cavities themselves by respective metal presses that are precisely shaped into the cavities containing them. The respective pellets are obtained in this way, and these pellets are held separated from each other by a separation partition. Each tablet is then removed from the cavity and inserted adjacent to the cup. The tablet is then joined by a final press through the use of a compression mold. A relief or positive-reverse engraving or the like may also be pressed and imprinted on the cosmetic surface.

  The number of cavities may vary from 2 to more than 5, thus obtaining a cosmetic product in which more than 5 tablets of different colors and shapes are arranged together inside the cup itself.

  However, such a method is very complex and expensive. This is because the metal cylinder in which the partition walls are arranged is difficult to implement and is generally very brittle because the partition wall thickness does not exceed 1 mm.

  Powder dosing systems are also difficult due to the high accuracy required by doses up to 0.5 g, and the doses themselves can fluctuate excessively even with minimal cosmetic adherence to the screw Because it is difficult.

  The form of compact cosmetics is also almost unsatisfactory because the color oozes out and penetrates into various sections.

  For this reason, to produce cosmetics with multicolor tablets in the same cup, currently the most used system pre-forms multiple tablets individually individually inside each pre-compression mold. Removing each tablet from its pre-compression mold, placing the tablets in combination in a cup using a vacuum transport system, and finally compressing using a press instrument. The press surface may be machined to allow the compressed cosmetic product to have relief, bulk and other effects.

  This method may be used to place 2 to more than 10 tablets in one and the same cup, but is particularly time consuming and labor intensive and expensive. This is because a separate pre-compression mold is made for each tablet, and a manufacturing operation is required for each tablet that is pre-compressed and combined in a cup. However, machining the cup provides very precise limits and size limits, for example making it less than 20 °, acute radius less than 0.5 mm and more. Things that are possible are not considered.

  Furthermore, one of the most negative aspects of such a system is that the assembly of multiple tablets should be performed while leaving some gaps between the various tablets, which Can be easily lowered into the cup. However, if the gap is excessive, the lines will be irregular, while if there is not enough space, the tablets may rub against each other during the descent step, and color intrusion or color protrusion between the tablets will then occur. Arise.

  If the formulation of each tablet is different from each other, the final compression step of the two connected surfaces is particularly likely to be a step that does not look good. It is by combining two or more cosmetic compounds that can be very different in density, consistency and formulation characteristics.

  This is almost true for the injected cosmetic compound, and using a fuser in the respective space of the cup or final container for the technology that allows the currently injected tablet cosmetic compound to be made in the same container. Allows the injection of different cosmetic compounds. The coupler is defined by one or more separators that are insertable and removable and of various shapes. The cosmetic compound to be injected is cooled until solidified, then the separator is withdrawn and transferred to another location. This allows the injection and solidification operations to be repeated until the last location is obtained.

  The separator is inserted inside the container to limit the space of each of the plurality of single tablets and to make them into the desired shape. The separator is generally made of metal, but may be made of plastic or other material. The basic requirement of the separator is that it can be removed from the separator wall without problems after the cosmetic compound has solidified.

  This usually results in a cosmetic product poured into the same cup or container so as to consist of a predetermined number of colors and shapes from a minimum of two to a maximum of five or more and fully connected to each other.

  The problems most commonly encountered by using such techniques are substantially related to the high manufacturing costs of separators using particularly elaborate and expensive manufacturing techniques, as well as the final cosmetic appearance results. This most cosmetic product is usually flat, usually without relief or bulk, but in addition, it is not necessarily uniform between the various parts, and the height difference between one tablet and the other tablet. There are often (level differences).

  An object of the present invention is to provide a method for producing a tablet cosmetic that avoids the above-mentioned problems.

  The manufacturing method of the tablet type powder or injectable cosmetic of the present invention is characterized by including the following steps.

Preparing each of a plurality of different slurry or semi-fluid cosmetic compounds;
Preparing a molded injection container having a side wall, a bottom part, and a plurality of separation partitions permanently fixed to the bottom part, the height of the partition wall being lower than the total depth of the container And allowing a plurality of adjacent individual spaces to be partitioned between a plurality of partition walls of the container,
Injecting the cosmetic compound into each of the adjacent individual spaces, wherein at least one of the injected cosmetic compounds crosses all the partition walls of the container to form an integrated part. Performing the injection,
A single tablet-type cosmetic which solidifies a plurality of injected cosmetic compounds and has an upper integrated part and an adjacent tablet made of a plurality of cosmetic compounds (4) formed downward from the integrated part Forming steps,
Pull out the solidified single tablet cosmetic from the container, turn the tablet cosmetic upside down, and form another tablet so that a plurality of tablets are formed with the integrated part down. Inserting inside the package.

  The cosmetic compound can be composed of a liquid carrier composed of water or an organic solvent or a powder dispersed in a solvent. Alternatively, the cosmetic compound can be constituted by an anhydrous compound that can be injected by heat.

The partition is permanently fixed to the bottom of the container. The partition is fixed to the container in a non-removable manner.

  The single tablet cosmetic can be solidified and oven dried. Alternatively, the single tablet cosmetic may be solidified by cooling.

  When the single tablet cosmetic is solidified, a hard material layer is used that can be adhered to the tablet cosmetic.

  According to the present invention, when manufacturing tablet-type powder or injectable cosmetics, equipment costs can be greatly reduced. In addition, manufacturing costs can be reduced. In addition, the appearance of tablet cosmetics will be excellent.

It is explanatory drawing which illustrates the outline | summary of the manufacturing method by this invention. It is explanatory drawing which illustrates the mode of the cosmetics inject | poured into the container by FIG. It is explanatory drawing which illustrates a mode that the cosmetics of FIG. 2 were extracted from the container. It is explanatory drawing which illustrates the other mode which extracted the cosmetics of FIG. 2 from the container. It is an external view which illustrates the container used for the manufacturing method of this invention. It is explanatory drawing which illustrates the cosmetics inserted in the last container. It is explanatory drawing which illustrates the other cosmetics inserted in the last container.

  The above objective is accomplished by a method that provides for the use of an infusion container with a plurality of partitions arranged at the bottom of the container itself.

  According to the novel invention, the septum can be made directly with the infusion container, significantly reducing equipment costs.

  Another good feature is that the number of shapes that can be obtained is very large. This manufacturing technique can be used for injection containers by plastic injection molding that allows even thicknesses within a few tenths of a millimeter to be reached without specific shape limitations and various templates.

The separation partition is fixed to the bottom of the container . That is, the separation partition can be produced directly and integrally with the injection container.

  In general, the fixed partition is made of metal, but other materials may be used instead, provided that the mechanical resistance is particularly high.

  1-4, an example of the outline | summary of the manufacturing method by this invention is illustrated succinctly. This manufacturing method uses an injection container having a plurality of fixed separation partitions.

  FIG. 1 shows a molded container 1 with a plurality of fixed partitions 2 arranged on the bottom thereof. The container 1 is filled with colored cosmetic compounds 4 in a plurality of individual spaces 5 partitioned by a plurality of partition walls 2. The colored cosmetic compound 4 is colored in the same or different color and has a slurry form or a semi-liquid form.

  The height of the partition wall 2 is lower than the total depth of the container 1.

  Injection of various cosmetic compounds into the plurality of individual spaces 5 is performed by using the dosing device 3.

  Such an operation can be injected in a single step. That is, a plurality of colors are injected up to the upper end of the partition wall except for the last color, and then the last color is injected until all other colors previously injected are overcome and integrated with each other. Or you may inject | pour so that it may mutually cross | intersect so that the cosmetic compounds injected simultaneously may couple | bond together (FIG. 2).

  As the dosing device to be used, a volume measuring device under pressure with a gear can be used. Alternatively, however, any suitable system used to inject a semi-liquid cosmetic into the cavity can be used accurately and without alternation of the cosmetic compound being injected.

  Similar to low temperature injection, high temperature injection of cosmetics at temperatures of 50-100 ° C. can also be carried out. The injected cosmetic product can then consist of a powder dispersed in a water carrier. Alternatively, the carrier may consist of water and an organic solvent.

  The injectable cosmetic product may be an anhydrous cosmetic product that can be injected by heating, such as a multipurpose cosmetic product, a lipstick, or a solid foundation.

  FIG. 2 shows a container 1 having a plurality of partition walls 2, in which a plurality of different cosmetic compounds 4 are filled in a plurality of individual spaces 5. After the cosmetic has solidified, it can be oven dried when the contained cosmetic is a slurry dispersed in an aqueous medium. Alternatively, if the cosmetic product contained consists of a thermally injectable anhydrous cosmetic product, it can be cooled and solidified completely.

  Containers intended to receive cosmetics in water and anhydrous injectable slurries generally consist of injection molded plastics such as SAN, ABS, SAN + ABS, PP and others.

  The container may be smooth or have reliefs and shapes of various heights and sizes.

  The container may be manufactured using a two-component resin such as PMMA or polyurethane resin, or a polymerizable two-component fluid silicone.

  In FIG. 3, the cosmetic product, indicated generally by 6, has its final form and has been solidified or dried. Here, 4 is an individual colored tablet. Each colored tablet 4 is separated from each other by a plurality of slots 7 by being injected into the respective cavities, and the slots 7 are produced by being extracted from the container 1 as a result of the separation partition 2.

  You may attach the support layer 8 made from a hard material to the bottom part of the solidified cosmetics (FIG. 4). Thereby, a piece can be kept as hard as possible, and the fixation of the piece in a final kit can be advanced.

  Such a support layer is generally made of plastic, ceramic, calcined clay, plastic mesh, or anything similar, and is secured when the cosmetic is solidified.

  The advantages obtained from this novel invention are apparent from the above description. That is a significant reduction in equipment costs. That is, the complicated and expensive metal equipment to be inserted into the container no longer has to be made. According to this system, the separation of the spaces intended for each cosmetic tablet is performed directly in one step, which is the step of preparing the infusion container.

  Another significant advantage is a reduction in manufacturing costs. If the injection that occurs at each step of the conventional system results in a huge expense for the personnel, the present invention allows more color injections to be performed simultaneously in a single step, thus reducing the production personnel's costs. This is because usage is significantly reduced.

  In terms of aesthetic appearance, the present invention eliminates all surface defects on the separation lines between different tablets, such as the invasion of different colors on different pedestals, the protrusion of colors on the separation lines, and the difference in steps between different tablets. Suppress overall. In fact, since the cosmetic is infused against the conventional system, the form left by the method is exactly the same as the form of the bottom wall of the respective cavity of the infusion container.

  In addition, by creating small gaps between the various tablets, the septum eliminates all possible color intrusion and contamination between tablets.

  As an example, FIG. 5 illustrates various forms of containers with a plurality of fixed partitions therein.

  As already mentioned, instead of a fixed septum, the same septum can be made removable by withdrawing it from the bottom of the injection vessel.

  6 and 7 show non-limiting examples of packages or kits (final containers) 9 used for cosmetics in tablets obtained by the method according to the invention.
