TECHNICAL FIELD [0001] The present invention relates to a liquid puff and a powder cosmetic puff,

The present invention relates to a liquid puff and a powder cosmetic puff and a method of manufacturing the same. More particularly, the present invention relates to a puff made of a polyurethane foam by cutting a pile of a polyester fabric to adjust the length of the pile and then bonding the polyurethane foam with a urethane sponge and a urethane adhesive, A waterproof layer is formed at the same time that the polyester fabric is not flowed so that the cosmetic material can be coated with adhesion, and then the sheet is sealed by ultrasonic welding so as to be a puff having a predetermined shape, The present invention provides a liquid puff and a powder cosmetic puff and a method for manufacturing the same, characterized in that the cosmetic is prevented from penetrating into the inside and the outside of the puff. According to the puff and the manufacturing method of the present invention, the puff can be used as a liquid cosmetic and a powder cosmetic puff Size of puff trim line The cosmetic material and the skin oil can be prevented from penetrating into the urethane sponge, the polyester fabric does not flow, the cosmetic material is applied in an adherent manner, the productivity of the puff is improved, and the production cost of the puff is lowered .

In modern society, makeup is accepted as a basic courtesy to modern people for social life. Especially for women, cosmetics are recognized as a necessity of everyday life. As interest and demand for cosmetics increase, so do the kinds of cosmetics as well as the number of portable cosmetics, and the demand for cosmetics that are easy to carry and use is increasing.

In particular, the largest volume of portable cosmetics, such as foundation, powder, Make-up cosmetics such as make-up cosmetics, which are small in size and thickness, have almost no space for accommodating puffs, and can be easily made thin because of their elasticity, cosmetic residue and skin oil are not penetrated into the puffs, Demand for cosmetic puffs that can prevent breeding is increasing.

The cosmetic puff is a cosmetic tool that allows the makeup cosmetic material to be closely adhered to the skin while being evenly applied to the skin, and is generally built in a makeup cosmetic container. These makeup puffs are divided into various types according to the materials and types of puffs. In general, the puffs are made of a material such as cotton, polyester, nylon, acrylic, and acetate, Sponge-like puffs such as a sponge, a nitrile butadiene rubber sponge, a polyurethane flocked foam sponge, a polyvinyl alcohol sponge, a styrene butadiene rubber (SBR), and a natural rubber (NR).

Generally, cosmetic puffs are classified according to the formulations of cosmetics. For example, velvet puffs can be used for solid foundation and powder cosmetic materials, and cosmetic materials can be added to liquid or gel foundation cosmetic materials. Use a sponge-like puff that is easily absorbable. If a velvet-like puff is used for a liquid or gel-like cosmetic, most of the cosmetic is absorbed into the puff and only a part of the cosmetic is applied to the skin, thus wasting the cosmetic. On the other hand, if the sponge-like puff is used for a solid or powder cosmetic, the surface of the puff is flat, so that solid and powder cosmetics are not uniformly applied and they are united.

The velvet-like puff is formed with a pile on the surface of the puff. Polyester, nylon, acrylic, acetate and the like are used as the material of the puff. Among them, the polyester puff is most widely used.

Generally, a velvet puff is produced by applying a glue to a polyester fabric and then applying a lint to the fabric to make a velvet fabric. The polyester fabric having a lint is cut into a predetermined size and prepared as upper and lower fabric members. The side faces are formed so as to face each other, and then the edges except for a part are sewn, inverted through the non-sewn portion, and then attached to the non-sewn portion. This manufacturing method requires all the processes to be performed by hand, so that the manufacturing process is complicatedly proceeding in a non-continuous manner, and an excessive number of workers and time are required. Depending on the skill of the operator, the puff may be twisted to one side, A deviation occurs in the quality such as cracking. The puff according to the above-described manufacturing method has a problem that the cosmetic residue is infiltrated into the inside of the puff to cause contamination of the puff and skin trouble, and the elasticity of the puff is low.

A prior art which improves this is Korean Patent Registration No. 10-0519408, which discloses that a film made of polyester or cotton material is placed on top and bottom of a sponge and heated and pressed by a roller compactor to produce a puff. The prior art has the effect of thermally bonding the sponge and the film to simplify the manufacturing process and reduce the cross-sectional thickness of the puff relatively. However, since the edges of the puff are not sealed, There is a problem that the shape is distorted. In addition, the cosmetic material can penetrate into the puff through the surface or side surface of the puff made of polyester or cotton, and the elasticity of the puff is low, so that it is difficult to apply the cosmetic material with adhesion.

In addition, since the conventional sponge-like puff is made of a porous material for absorbing cosmetic material having liquidity or gel-like flowability and is applied to the skin, cosmetic material is absorbed excessively into the puff, so that the amount of cosmetic material consumed is large, It is deteriorated to cause bacterial reproduction and skin trouble, and the durability of the puff is deteriorated.

Furthermore, liquid or gel-like foundations, powders, And cosmetics having various formulations such as cosmetics, cosmetics, cosmetics, and the like are mixed according to the user's preference, so that they can be buried in puffs regardless of the formulations of cosmetics, It is necessary to research and develop puffs which can be applied evenly.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above problems and to provide a puff which can be used both as a conventional solid foundation, a powder cosmetic composition and a liquid cosmetic composition. After cutting to an appropriate length, the polyester fabric is adhered with a urethane sponge and a urethane adhesive so that a waterproof layer is formed without waterproof laminating the urethane sponge, and at the same time, the polyester fabric is prevented from flowing, And then sealing the sheet with an ultrasonic welder so as to be a puff having a predetermined shape, and cutting the sheet so that the cosmetic is prevented from penetrating through the puff surface and the side surface, and a method for manufacturing the liquid puff and the powder cosmetic puff. Thus, the liquid and powder cosmetic The size of the cutting line of the puff can be reduced and cosmetic and skin oils can be prevented from penetrating into the urethane sponge, the cosmetic material can be applied in close contact, the productivity of the puff can be improved, It is confirmed that the production cost is lowered, and the present invention has been completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a liquid puff and a powder cosmetic puff according to the present invention will be described in detail with reference to the accompanying drawings.

The liquid puff and the powder cosmetic puff according to the present invention are made of a sheet of a polyester fabric and a urethane sponge joined together by a urethane adhesive agent, wherein a urethane adhesive is applied and adhered between the polyester fabric and the urethane sponge, .

The polyester fabric according to the present invention refers to a fabric in which a polyester pile is formed on the polyester fabric surface. Since the polyester fabric itself has low hygroscopicity, molds are not readily generated, and skin feel is excellent .

The pile made of polyester in the present invention is preferably formed of microfine fiber, microfiber fiber (micropoly fiber) or micro velvet hollow fiber.

The microfine fiber is a polyester fiber having a denier of 0.1 to 0.4 denier, the thickness of the fiber is small, the dustiness of the powder cosmetic is small, the liquid cosmetic can be easily adsorbed, and the skin feel is excellent.

The microfiber fibers (microfiber fibers) are polyester fibers having a denier of 0.001 to 0.1 denier, and are superior in absorbency to liquid and powder cosmetics due to their excellent capillary action due to the microfibers themselves, and are excellent in skin feel.

The micro-velvet hollow fiber is a micro-sized polyester fiber having an air layer inside the fiber. The micro-velvet hollow fiber is lightweight compared to the apparent volume, has excellent elasticity and air permeability, has a large specific surface area per unit area and is excellent in absorbency and easily adsorbs powder and liquid cosmetic It can be applied to the skin.

As shown in Fig. 1, the liquid and powder cosmetic puffs of the present invention and the method for manufacturing the same have the steps of: (S10) cutting a pile of polyester fabric; Applying a urethane adhesive to the surface of the urethane sponge (S20); In step S20, the polyester fabric of step S10 is bonded to the surface of the urethane sponge coated with the adhesive, wherein the surface of the polyester fabric on which no pile is formed is adhered to the urethane sponge to form a waterproof layer Producing a sheet; And a step (S40) of sealing the sheet of the step (S30) by ultrasonic welding and cutting the sheet into a puff having a predetermined shape.

The manufacturing method of the present invention will be described separately for each step.

First, a step S10 of cutting a file of the polyester fabric is performed. The step S10 is a step of cutting the pile formed on the surface of the polyester fabric so as to adjust the length of the pile. The thickness of the puff made of the puff according to the manufacturing method of the present invention, It affects elasticity.

The file length of the polyester fabric cut in the step S10 may be adjusted according to the thickness of the polyester fabric file, and is preferably 0.5 to 2.1 mm. If the file length of the polyester fabric is less than 0.5 mm, the file is completely compressed by the pressure during the production of the sheet in step S30 so that the surface of the sheet becomes flat or hard and the powder cosmetic material is put on the surface of the puff There is a problem that it becomes difficult, and there is a problem that the elasticity of the puff is deteriorated. On the other hand, if the file length of the polyester fabric is more than 2.1 mm, the length of the file is too long, so that the files are piled together and the feeling of soft feeling of the puff is lowered, or the liquid cosmetic material is excessively deposited on the surface of the puff, , The fusing pressure and the welding time are prolonged in step S40 or the cutting line is formed to be wide.

A step (S20) of applying a urethane adhesive to the surface of the urethane sponge is performed. The step S20 is a step of applying a urethane adhesive to the surface of the urethane sponge while the urethane sponge is conveyed by the roller, and the urethane adhesive may be applied to one or both sides of the urethane sponge. At this time, the speed of the roller is preferably 15 to 20 yd / min.

If the speed of the roller is less than 15 yd / min, the urethane adhesive is excessively applied to the surface of the urethane sponge, so that the urethane adhesive can flow out during the sheet preparation in step S30 and the ultrasonic welding in step S40, There is a problem that the waterproof layer is thickly formed to reduce the elasticity of the puff and the feeling of skin touch. When the roller speed is more than 20 yd / min, the urethane adhesive is not evenly applied to the surface of the urethane sponge, There is a problem that a waterproof layer is not formed on the surface of the urethane sponge.

In step S20, the polyester fabric of step S10 is bonded to the surface of the urethane sponge coated with the adhesive, wherein the surface of the polyester fabric on which no pile is formed is adhered to the urethane sponge to form a waterproof layer A step S30 of manufacturing a sheet is performed.

The step (S30) is a step of producing a sheet by applying a urethane sponge and a polyester fabric with a roller while applying pressure and heat to the sheet to produce a sheet. The sheet is pressed at a pressure of 0.01 to 0.1 bar, a temperature of 100 to 210 캜, min. < / RTI >

If the pressure is less than 0.01 bar, a sufficient force is not applied to the urethane sponge and polyester fabric, and there is a problem that the urethane sponge and the polyester fabric are not completely bonded. If the pressure exceeds 0.1 bar, the polyester fabric There is a problem that the sheet is excessively compressed, the surface of the sheet is hardened, and the elasticity of the puff and the feeling of skin touch are reduced.

If the temperature is less than 100 ° C., heat is not sufficiently transferred between the urethane sponge and the polyester fabric, and the urethane sponge and the polyester fabric are not completely bonded or the waterproof layer formed by the urethane adhesive is not uniformly formed. Is higher than 210 DEG C, there is a problem that the surface of the polyester fabric and the urethane sponge is burned or the color is discolored due to the high temperature.

When the speed is less than 15 yd / min, the time required for producing the sheet is excessively consumed, resulting in a problem that the productivity of the puff is lowered and the color of the polyester fabric is discolored. If the speed is more than 20 yd / min, the urethane sponge and polyester There is a problem that the force is not uniformly transmitted to the fabric, and the urethane sponge and the polyester fabric are not completely bonded.

The sheet is formed by a polyester fabric adhered to one surface or both surfaces of a urea sponge by a urethane adhesive, and a waterproof layer formed thereon. The cosmetic material embedded in the polyester fabric is not penetrated into the urethane sponge, thereby preventing contamination of the urethane sponge or prevention of germs When the cosmetic material is applied, the polyester fabric is separated from the urethane sponge or is not pressed, so that the cosmetic material can be applied in close contact.

The sheet of the step S30 is sealed by ultrasonic welding and cut to form a puff having a predetermined shape (S40).

In the present invention, ultrasonic welding is performed by converting electrical energy generated from a power source into a mechanical energy when it is applied to a vibrator through an oscillator, amplifying the mechanical energy through a booster, and then transmitting it to a bonding surface of the object to be welded through a horn. And instantaneous frictional heat is generated by the vibration to melt the joint surface and cause fusion.

The step (S40) is a step of sealing the edge of the puff of a predetermined shape by ultrasonic welding using an ultrasonic welder, cutting the outer surface of the sealed surface by a cutting machine, and cutting the same at the same time. In the step (S40) A known ultrasonic welder, a cutting machine, and a known cutting machine are used. The step S40 is a process that can be implemented using a known product, and a detailed description thereof will be omitted.

The ultrasonic welding in step S40 is preferably performed at a frequency of 20 to 40 KHz, a welding pressure of 1 to 5 kg / cm 2, a friction heat of 20 to 50 ° C, and a welding time of 1 to 3 seconds.

If the frequency is less than 20 Khz, sufficient frictional heat is not generated at the edge of the puff having a predetermined shape, so that the fusion is not properly performed, the fusion takes a long time, and the cutting line is widened to increase the amount of the discarded sheet. If the frequency exceeds 40 KHz, there is a problem that the melting is severely generated at the edge of the puff having a predetermined shape or the puff itself is damaged.

If the fusing pressure is less than 1 kg / cm < 2 >, the sheet may be skewed, pressure may not be uniformly transmitted to the edge of the puff having a predetermined shape so that fusion may not be properly performed and the cosmetic may be absorbed into the puff through the side surface of the puff There is a problem. If the fusing pressure is more than 5 kg / cm 2, the sealing efficiency of the edge of the puff having a predetermined shape is not significantly increased as compared with the pressure increase, and the flash (flash, around the portion where the horn of the ultrasonic fuser was located) And the cosmetic material is absorbed into the inside of the puff.

If the frictional heat is less than 20 占 폚, the edge of the puff having a predetermined shape is not sufficiently melted to cause fusion, and the cosmetic material is absorbed into the puff through the side surface of the puff. The edges of the puffs of the puffs are excessively melted and the urethane adhesive flows out to deteriorate the quality of the puff.

If the fusion time is less than 1 second, there is a problem that fusion of the puff edge of the predetermined shape is not properly performed. If the fusion time is more than 3 seconds, flash is formed around the puff edge of the predetermined shape The excess portion of the material is raised), or the cosmetic can be absorbed into the puff, and the cutting line is formed to be wide.
