Description

  The present invention relates to a cosmetic product including a mascara composition and an eyelash treatment device, and the mascara composition is applied to the eyelashes by fluidizing the mascara composition with heat generated by the eyelash treatment device.

Mascara products are used to increase the beauty of the human eye by providing a coat to the eyelashes, giving them thickness, length and color to shape their own eyelashes. Over the past 60 years, mascara products have been provided as mascara applicators with applicator brushes attached to the handle, and applicators in containers such as tubes containing liquid to semi-solid mascara compositions. Immerse the tip of the brush. The mascara composition is usually an emulsion in which wax and pigment are dispersed in water or other volatile carrier. The mascara composition and its transfer system are limited by emulsion and solution chemistry and are applied in a wet state and then dried to form a mascara film to set and maintain the eyelashes.

  Liquid or semi-solid mascara compositions exhibit low viscosity performance and a low yield point, and therefore are liable to bleed and soil after being applied to eyelashes. A solid component such as a wax dispersed in the composition becomes a lump because the film is not smooth and difficult to apply.

  In other respects, solvent and composition carriers that do not evaporate on time also cause bleeding and soiling after application to the eyelashes. The so-called water-resistant mascara is intended to solve this problem using volatile hydrocarbon solvents. Such a volatile hydrocarbon solvent has good storage stability but sacrifices usability and beauty. Furthermore, it is necessary to consider the odor and safety aspects of volatile hydrocarbon solvents.

  One solution to provide a mascara composition with good performance and durability is to create a solid composition, in which case the composition is heated prior to application to the eyelashes for use Sometimes softened or smoothed. Such heating also has the advantage of shortening the volatilization time after application. The solid film applied to the eyelashes after application has a significantly higher yield point than the film obtained with a conventional mascara composition and is less likely to bleed or soil.

  In view of the above, there is a demand for mascara products that can apply solid mascara compositions to eyelashes safely and effectively. It is also useful to provide a mascara composition in a predetermined amount so that an appropriate amount of composition for application to the eyelashes can be easily provided to the user.

By the way, in this field, as shown in, for example, International Patent Publication No. WO99 / 22782, an eyelash curling device that is a combination of an applicator brush and a heater has been proposed. However, the application brush here is designed to curl the eyelashes by heating while applying a liquid or semi-solid mascara composition taken out of the container. Due to the lack of the concept and structure for heat fluidizing the mascara composition, it is virtually impossible to use this application brush in combination with the mascara composition proposed in the present invention. There is a need for a dedicated processing device for applying such a mascara composition to the eyelashes appropriately and uniformly, making maximum use of such a mascara composition. Furthermore, it would be desirable to provide a processing apparatus with loading means for removing a predetermined amount of mascara composition at the time of use.
None of the prior art provides the advantages or benefits of the present invention.

The cosmetic product of the present invention comprises a mascara composition and an eyelash treatment device, so that the mascara composition is softened by heat and applied to the eyelashes to form a solid film on the eyelashes. This film has high durability. Have This product enhances the performance of the mascara composition and can be safely used by ordinary users.
This mascara composition is solid at room temperature, but softens at high temperatures and is applied to the eyelashes. The eyelash treatment device includes a heater that provides sufficient heat to the mascara composition, and this heater is safe against eyelashes even in accidental situations where the user accidentally touches the device with eyelashes or eyeballs. The eyelash treatment apparatus includes an applicator for taking a mascara composition, heating (softening) it, and applying it.

  When the softened mascara composition is applied to the eyelashes, the mascara composition is rapidly cooled by the atmosphere and solidified. The mascara composition applied to the eyelashes in this way forms a strong film that covers the eyelashes, and does not soften due to body temperature, giving high durability.

  In particular, the mascara composition of the present invention exhibits the above performance by containing a solid hydrophobic component that provides specific rheological properties. The rheological properties of this composition are defined by the needle penetration value, yield stress, and viscosity measured according to ASTM (American Society for Testing and Materials) test method D5. The mascara composition of the present invention has a needle penetration value at 25 ° C. of about 1 to about 40, a yield stress of about 1500 Pa, and a viscosity at 100 ° C. of about 1 mPas to about 10,000,000 mPa. For this reason, the mascara composition having the above rheological properties is applied to the eyelashes while being softened by heating, and is solidified on the eyelashes to form a strong film on the eyelashes.

  This mascara composition can be prepared as an oil mixture in which the solid hydrophobic component is the oil phase. The mascara composition may also be a water-in-oil emulsion with added water or emulsifier.

  Furthermore, pigments or film-forming polymers for enhancing aesthetic effects and durability can be added to the composition.

  The device according to the present invention is specifically designed to have a structure that softens the mascara composition and retains the softened mascara composition for uniform application to the eyelashes. The apparatus comprises an applicator with a heater that softens the mascara composition and a comb lined up along the length of the applicator. The comb is aligned along the length of the applicator and covered with a softened mascara composition. Thereby, the softened mascara composition is successfully passed from the full length of the comb to the eyelashes, leaving a solid mascara film on the eyelashes.

  The apparatus of the present invention is further provided with loading means for providing a predetermined amount of the mascara composition in use. This loading means can be provided on a cap that covers the applicator. By providing the device with a predetermined amount of loading means, the user can easily give an appropriate amount of the composition to the eyelashes.

  The loading means is configured to hold a plurality of mascara pieces and feed them one by one to the applicator to provide the mascara composition in an appropriate amount.

  The cap includes a sheath that is attached to the applicator, and the sheath is formed with an opening that communicates with the applicator. The loading means includes a carrier having a plurality of filling chambers, and each filling chamber holds a piece of mascara composition. The carrier is movable with respect to the sheath, and selectively mating one of the plurality of filling chambers to the opening allows the mascara composition pieces to be passed through the opening to the applicator.

  Preferably, the carrier is provided as a sleeve coaxial with the sheath and rotatable about the axis of the sheath. In this case, the sleeve can be provided with a plurality of gates that normally close the filling chamber, and the gate rotates to open the corresponding filling chamber to feed the mascara pieces.

  This opening can be provided with a normally closed valve. In this case, the loading means is provided with a plunger for pressing the mascara piece and temporarily opening the valve to feed the mascara piece to the applicator.

  The carrier can be a disk with a plurality of filling chambers that are rotatable about a vertical axis perpendicular to the axis of the sheath and are arranged around the vertical axis. According to this configuration, the mascara pieces can be delivered simply by rotating the disk around a vertical axis perpendicular to the axis of the sheath or applicator.

  The mascara pieces can be held in each filling chamber by a breakable seal. In this connection, the loading means is provided with a plunger for pressing the mascara piece and breaking the breakable seal to deliver the mascara piece to the applicator. By using a breakable seal, the mascara pieces are kept in good condition for a long time, but can be easily loaded into the applicator.

  The filling chambers formed in the disk may be spaced apart along the circumferential direction and the radial direction so that a pair of filling chambers arranged in the radial direction matches an opening that is elongated along the axial direction of the sheath. . With this configuration, two or more mascara pieces can be sent out to the applicator at points separated in the radial direction.

  Instead of using a movable carrier that holds the mascara pieces, the loading means is equipped with a feeder that is a screw-type piston that feeds the mascara pieces linearly towards an opening with a normally closed flap valve. be able to. The loading means is further provided with a plunger that presses a piece of mascara near the opening against the flap valve to temporarily open the flap valve. For this reason, a mascara piece can be sent out by operating combining a feeder and a plunger.

  Instead of the above screw-type piston, the mascara piece can be sent out simply by pushing the plunger by using a feeder as a spring biased piston type.

  Further, the loading means is configured such that a hopper including pellet-shaped mascara pieces is formed at one end of the sheath at a position away from the opening, and a screw conveyor extends into the filling chamber to supply pellets from the hopper to the opening. You can also Thereby, the mascara piece can be sent out in an appropriate amount by operating the screw type conveyor and adjusting the moving amount of the conveyor.

Features and advantages of the present invention described above, by reading the disclosure scope and the invention according to the appended become apparent to have you to those skilled in the art.

  While the claims of this specification explicitly point to the invention, it is believed that the invention can be better understood from the following description. The product according to the present invention is a combination of a mascara composition and an eyelash treatment device.

Mascara Processing Device FIGS. 1 to 4 show an eyelash processing device according to a preferred embodiment of the present invention. The apparatus uses a solid mascara composition . This composition is solid at room temperature, ie 25 ° C., softens at high temperatures and can be applied to the eyelashes. In this specification, “solid” describing a mascara composition means that the composition has a predetermined hardness, maintains its structure, and is stable to stress and shearing force. This mascara composition undergoes a transition change in terms of rheology between 25 ° C. and 100 ° C., and in this temperature range, a temperature range and rheology where the composition softens properly for use in eyelashes are obtained. It is done. In a softened state, the mascara composition has sufficient fluidity to be applied to the eyelashes, but it stops on the applicator during application and has a viscosity sufficient to stop on the eyelashes after application.

  The apparatus includes a long handgrip 10 and an applicator 20 for applying a softened mascara composition to a user's eyelashes at one end. The applicator 20 has a length substantially aligned with the length of the handgrip 10 and includes a heater 40. The heater heats and softens the mascara composition after it is loaded into the applicator, while heating and curling the eyelashes. The mascara composition is prepared as a solid piece and is held by a cap 100 that is detachable from the applicator. As will be described later, the cap 100 is configured to include a loading mechanism for loading, that is, sending out, mascara pieces one by one to the applicator.

  The applicator 20 includes a head 22 that integrally extends from the grip 10 and a comb attachment 30 that is detachable from the head 22. The head 22 is formed of an insulating plastic material and is equipped with a heater 40. The heater is formed of a resistance coil 42 wound around a U-shaped core 44 made of an insulating material, and forms two vertical rows that run along the length direction of the applicator 20. The coil 42 is connected to a voltage source, that is, a battery in the grip 10, and is energized by operating the switch handle 14 on the side surface of the grip 10. The comb attachment 30 is made of an insulating plastic material, is mounted on the head 22 in a heat transfer relationship with the heater 40, and is heated to a high temperature to soften the mascara composition. The comb attachment 30 has a curved upper surface, and the upper surface is provided with a comb in which a plurality of comb teeth 32 are arranged along the length and width directions of the applicator 20, and a softened mascara composition is applied to the eyelashes while combing the eyelashes. . A groove 34 is formed in the center of the upper surface in the width direction to accommodate the upper end portion of the heater 40 and to provide a space for holding the softened mascara composition. The softened mascara composition is then prepared to flow into the comb teeth, scoop up the comb teeth 32 by the action of surface tension, and be sent to the eyelashes when combing the eyelashes with the comb teeth.

  In operation, the applicator 20 is initially placed in a position where the comb attachment 30 is just below the eyelashes, as shown in FIG. Then, as shown in FIG. 21, the applicator 20 is lifted and rotated somewhat to comb the eyelashes with the comb teeth 32, thereby applying the softened mascara composition to the eyelashes while lifting the eyelashes. In this state, the upper surface of the comb attachment 30 comes into contact with the eyelashes to heat and curl the eyelashes. As shown in FIG. 22, when the applicator 20 is released from the eyelashes, the softened mascara composition is rapidly cooled to give the eyelashes a firm film of the solid mascara composition. Thus, the mascara film can be formed and the eyelashes can be curled by a single operation.

  The heater 40 heats the comb attachment 30 to a temperature of about 50 ° C. to 100 ° C. to soften the mascara composition. At such high temperatures, the softened mascara composition exhibits a viscosity of 1 mPas to 10,000,000 mPa, which is sufficient for application to the eyelashes but prevents it from falling off the applicator 20, and the mascara composition It can be applied safely.

The percentages, quantities, and ratios of all mascara compositions are based on the total weight of the composition of the present invention unless otherwise stated. All such weights for the ingredients are based on activity levels and thus do not include carriers or by-products that may be included in commercially available materials.

  The active ingredients and other ingredients useful in the present invention are classified or described based on cosmetic or therapeutic efficacy or hypothetical mode of action. However, active and other ingredients useful herein are those that, in some cases, provide more than one cosmetic or therapeutic effect, or act through more than one mode of action. Accordingly, the classification here is done for convenience, and the components are not limited to the specifically described application.

  The mascara composition of the present invention is solid at room temperature, that is, 25 ° C., and softens at high temperature and can be applied to eyelashes. In this specification, “solid” describing a mascara composition means that the composition has a predetermined hardness, maintains its structure, and is stable to stress and shearing force. The composition of the present invention has a needle penetration value of about 1 to about 40 and a yield stress of about 1500 Pa measured at 25 ° C., preferably 35 ° C., according to ASTM (American Society for Testing and Materials) test method D5. is there.

  The measurement of the needle penetration value based on ASTM test method D5 is carried out by placing a standard needle (2.5 g in a 47.5 g needle holder, 50 g in total) on the composition for 5 seconds. Is expressed in millimeters. Yield stress measurement measures an oscillatory stress sweep to interpret the flow performance and viscoelastic properties of a fluid or semi-solid as a function of stress, shear rate, and temperature. In the present invention, the yield stress was measured at 1 Hz using a 40 mm aluminum parallel plate (gap 60 mm) with a TA Instruments rheometer AR-500. It is desirable that the yield point of the composition of the present invention is not measured in a state where it is subjected to stress or shearing force at 25 ° C.

  The mascara composition changes its rheology when heated and reaches a point where it becomes liquid at 100 ° C, preferably 90 ° C. In this specification, reference to a mascara composition as “liquid” means that the composition has a viscosity of about 1 mPas to about 10,000,000 mPas. The mascara composition of the present invention undergoes a transition change in terms of rheology between 25 ° C. and 100 ° C., and in this temperature range, the temperature range and rheology at which the composition is appropriately softened for use in eyelashes. Is obtained. In a state where the mascara composition is softened, the applicator has sufficient fluidity to be applied to the eyelashes with an average number of strokes while the composition is held, but the application stops on the applicator, After application, it has sufficient viscosity to remain on the eyelashes. If the composition is too thin or watery, it is difficult to hold on the applicator and the amount of composition applied to the eyelashes is reduced.

  The mascara composition is prepared to have rheological properties that provide suitable rheology in the temperature range in which the eyelash treatment device is heated. This temperature range is selected to provide an appropriate balance between mascara composition applicability and eyelash curl lift efficacy. Usually, this temperature range is 50 ° C to 100 ° C.

  Alternatively, the mascara composition can be composed of an outer shell made of a solid hydrophobic component having at least the above-mentioned specific rheological properties and an inner core having a predetermined viscosity. This mascara composition is in a solid state covering the flowable inner core at room temperature. After heating, the crystallization time is given before the composition solidifies, giving the user the appropriate time to apply the composition to the eyelashes and solidify. Such a long “play time” allows use to give the eyelash the desired shape.

  The inner core can be an aqueous sustaining component containing 15% to 95% moisture by weight. The inner core of such an aqueous continuous phase can be washed away with soap or water. The inner core can also be an oily sustaining component comprising 30 wt% to 50 wt% volatile liquid oil.
