Description

[Technical field]

[0001] The present invention relates to a puff, and more particularly to a cosmetic puff. [Background technology]

[0002] In general, cosmetic puffs are made of sponge-shaped foams made of materials such as latex, urethane, flocking, PVA (Poly Vinyl Alcohol), rubber, etc., and are used to apply cosmetics (i.e., cosmetics) such as foundation, skin cover, twin cake, powder, etc. to the puffs and tap them on the face when applying makeup to body parts such as the face, so that the cosmetics are evenly applied to the face and effectively absorbed. Such puffs are manufactured and used in various shapes according to the type of cosmetics and the container structure, and are usually made in the shape of a relatively thin rectangular or disc. In particular, in recent years, due to the diversification of cosmetics and containers, cap-shaped puffs that are attached to cosmetic containers and circular or square plate-shaped puffs that are directly used by the user with their hands are used.

[0003] The above-mentioned conventional cosmetic puffs are manufactured by cutting a urethane sponge into a circular or square plate, and the underside of the urethane sponge is bonded with a polyurethane material called Rubycel so that the makeup can be spread and applied evenly with a moist and soft feeling when it comes into contact with the skin of the user, and a handle or the like for the user to hold with his or her hand is bonded to the upper surface, and synthetic leather made of a Jones material is bonded to the upper surface.

[0004] Such conventional cosmetic puffs are attached using a general adhesive method, and after absorbing cosmetics through the bottom surface made of Rubycel, the user grips the top surface made of synthetic leather or uses a handle or the like formed on the top surface to apply the cosmetics absorbed on the bottom surface to the face or skin in a tapping motion.

[0005] However, when makeup is applied to the face or skin in the above-mentioned manner using a conventional cosmetic puff, the cosmetic absorbed on the underside of the Rubycell material is absorbed into the urethane sponge, and the cosmetic to be applied does not remain on the underside of the Rubycell material. Instead, the user continues to touch the underside of the cosmetic puff to the cosmetic to absorb it, and the cosmetic is again absorbed into the urethane sponge. This series of processes is repeated, resulting in a large amount of cosmetic being consumed.

[0006] Furthermore, although the urethane sponge acts as a cushion to absorb the amount of impact applied to the skin in the process of applying cosmetics to the face or skin by tapping the skin when applying makeup, allowing the cosmetics to be applied more softly and widely to the face or skin, if the cosmetics are continuously absorbed from the underside of the cosmetic puff, the cosmetics harden and the cushioning ability decreases, which causes some discomfort to the user when using the cosmetic puff, and gives rise to problems such as an unhygienic condition.

[0007] Furthermore, as the cosmetics absorbed in the urethane sponge remain, problems such as bacterial proliferation occur, making it impossible to maintain hygienic cleanliness. This makes it impossible to continue using the cosmetic puff due to its characteristics of coming into direct contact with the user's face and skin, and shortens its useful life.

[0008] Conventional cosmetic puffs use urethane sponge as a cushioning material. Built-in When fine powder, liquid, gel, or other cosmetic product is applied to the underside of the puff and then slapped on the face, the cosmetic product is discharged to the upper side of the puff through the lower part made of a breathable sponge material and the mesh-like cushion member, which results in a large amount of cosmetic product being applied and ultimately using a large amount of cosmetic product, which causes problems of waste and contamination of the user's hands with cosmetic product.

[0009] Therefore, Prior Art Document 1 discloses a puff in which a barrier film made of an adhesive component is laminated onto one surface of the puff member of the cosmetic puff and then heated and pressed, so that the barrier film is impregnated into the one surface of the puff member and bonded.

[0010] However, such conventional barrier films are impregnated into the puff member through heat and pressure bonding at 130 to 150°C, and problems arise with some parts being impregnated into the gaps of the puff member during the heat and pressure bonding process and some not. That is, this is a technology that prevents the cosmetic from being absorbed excessively by impregnating the gaps of the puff member and blocking the gaps of the puff member, but by impregnating the puff member through heat and pressure bonding, some gaps of the puff member are not impregnated, making it difficult to completely block the absorption of the cosmetic (although the claims in Prior Art Document 1 state that it is impregnated, in reality it is determined that fusion occurs during heat and pressure bonding, and it is fused and is mostly deformed while having heat curing properties).

[0011] For this reason, Prior Art Document 2 discloses a cosmetic puff in which a pumping barrier membrane is formed between a lower puff member that comes into contact with the skin and an upper puff member that comes into contact with the user's hand, and upper and lower air cells are formed between the lower and upper puff members centered around the pumping barrier membrane, so that the cosmetics are absorbed only by the lower puff member, and the upper puff member is blocked from absorbing cosmetics while maintaining its shock-absorbing ability, thereby halving the role of the cosmetic puff.

[0012] However, in such a cosmetic puff, the cosmetic absorbed in the lower puff member flows into the space between the lower puff member and the pumping barrier film and then hardens, which may shorten the life of the cosmetic puff. [Prior art documents] [Patent documents]

[0014] The present invention has been made to solve the above-mentioned problems of the conventional technology, and an object of the present invention is to provide a cosmetic puff having a compact structure to maximize shock absorbing capacity while exhibiting dischargeability to minimize the amount of cosmetics remaining in the urethane foam. [Means for solving the problem]

[0015] A cosmetic puff according to one embodiment of the present invention includes a use surface layer, a gripping surface layer, a first urethane foam layer formed between the use surface and the gripping surface in contact with the use surface, and a second urethane foam layer formed between the use surface and the gripping surface in contact with the gripping surface, wherein the first urethane foam layer has an opening pillar having a set width in a direction perpendicular to the use surface or the gripping surface.

[0017] Also, the barrier layer may be formed by adhering to the first urethane foam layer or the second urethane foam layer.

[0018] Also, the barrier film layer may be formed between the first urethane foam layer and the second urethane foam layer to maintain airtightness.

[0019] Also, the open post may be formed such that one end contacts the application surface layer and the other end contacts the barrier layer.

[0020] In addition, the thickness of the first urethane foam layer may be greater than the thickness of the use surface layer, and the open pillar may be formed to have a height corresponding to the thickness of the first urethane foam layer.

[0033] A cosmetic puff according to an embodiment of the present invention will be described below. Figure 1 is a cross-sectional view of the cosmetic puff according to an embodiment of the present invention, Figures 2 and 3 are photographs of the cosmetic puff according to an embodiment of the present invention, Figure 4 is a photograph of the puff with the use surface removed from Figure 2, Figure 5 is an enlarged photograph in which the opening pillar in Figure 4 can be clearly seen, and Figure 6 is a cross-sectional photograph of the cosmetic puff in Figure 2 cut perpendicular to the use surface.

[0034] Referring to the drawings, a cosmetic puff 1000 according to one embodiment of the present invention includes a use surface layer 100 , a first urethane foam layer 200 , a barrier layer 300 , a second urethane foam layer 400 , and a gripping surface layer 500 .

[0035] The use surface layer 100 is a part that comes into direct contact with the skin of the user after it has absorbed or applied the cosmetic by directly contacting the cosmetic. It is formed in a circular or square plate shape, and is formed so that it can apply or absorb the cosmetic, come into direct contact with the face or skin of the user, and apply the cosmetic evenly to the face or skin by tapping or hitting. Here, the use surface layer 100 is formed in a circular or square plate shape as described above, and comes into direct contact with the skin of the user. Therefore, it is preferable that the use surface layer 100 is made of a Rubycell material or an equivalent material. Rubycell is a type of synthetic resin called polyurethane, and the amount of foundation absorbed (absorbed) by the Rubycell puff is less than that of an NBR (Nitile Butadien Rubber, a type of synthetic rubber) puff, and it has superior antibacterial properties and is more hygienic than an NBR puff. Rubycell also has excellent application properties, adhesion to the skin, and covering power by absorbing the cosmetic and adhering to the skin.

[0036] The first urethane foam layer 200 is formed to correspond to the above-mentioned use surface layer 100, and is bonded to the upper surface of the use surface layer 100 so as to cushion the impact applied when the use surface layer 100 comes into contact with the face or skin of the user, prevent the cosmetic generated from the use surface layer 100 from scattering by absorbing the impact, and apply the cosmetic evenly to the face or skin. Here, the first urethane foam layer 200 is preferably formed of urethane or polyurethane. In general, urethane sponge has excellent elastic recovery and restoration ability, and therefore can help the use surface layer 100 to quickly restore its original state when deformed, and can perform a cushioning function so that the user can apply the cosmetic gently by absorbing the impact of the hand during the makeup application process, and can also prevent the cosmetic from scattering due to excessive impact, i.e., in the case of the cosmetic formed into powder due to impact, the cosmetic is scattered into the air or scattered without being evenly applied. Therefore, by maintaining the elastic recovery force of the first urethane foam layer 200, the shape of the use surface layer 100 is maintained for a long period of time, thereby extending the service life and allowing the puff to come into contact with the skin over a wider area than when applying makeup, making it easier to apply makeup.

[0037] Furthermore, in the case of the cosmetic puff according to one embodiment of the present invention, a second urethane foam layer 400 having approximately the same thickness and made of the same material as the first urethane foam layer 200 is further bonded to the first urethane foam layer 200. Therefore, the above-mentioned use surface layer 100 quickly returns to its original state when deformed, and further cushions the impact generated when the user hits the puff while applying makeup, thereby further preventing the scattering of cosmetics due to excessive impact.

[0038] However, as mentioned above, when air cells or the like, which are separate spaces, are formed between the first urethane foam layer 200 and the second urethane foam layer 400, as in prior art document 2, even if such impacts can be mitigated, the decorative material may be adhered to such air cells or the decorative material may be transmitted from the first urethane foam layer 200 into the second urethane foam layer 400 and absorbed.

[0039] Therefore, in Prior Art Document 2, a pumping barrier membrane (not shown) was provided between the first urethane foam layer 200 and the second urethane foam layer 400 to prevent the decorative material from being transmitted from the first urethane foam layer 200 to the second urethane foam layer 400 and absorbed, but it was still not possible to prevent the decorative material from becoming stuck inside the air cells, as in Prior Art Document 2.

[0040] Therefore, the cosmetic puff 1000 according to an embodiment of the present invention has a barrier layer 300 formed between the first urethane foam layer 200 and the second urethane foam layer 400, and the barrier layer 300 is formed by adhering to the first urethane foam layer 200 or the second urethane foam layer 400. More preferably, the barrier layer 300 is formed by always adhering to the first urethane foam layer 200 so that air cells to which the cosmetic material is fixed are not formed. Furthermore, in consideration of the cushioning force, it may be preferable that the barrier layer 300 is not adhered to the second urethane foam layer 400 even in this case, and a space such as an air cell is provided therebetween.

[0041] Meanwhile, in this case, the barrier layer 300 is flexible and fluid, and acts as a separator that maintains airtightness so that air does not pass through at all. Therefore, it prevents the cosmetic material from flowing from the application layer 100 to the gripping layer 500, and expels the air contained in the first urethane foam layer 200 to the outside, minimizing skin irritation and improving the ease of application of the cosmetic.

[0042] Furthermore, the barrier layer 300 prevents the air filled in the second urethane foam layer 400 from escaping, thereby improving the cushioning ability against external shocks and improving the comfort of use.

[0043] The barrier layer 300 is preferably made of any one of OPP (oriented polypropylene) vinyl, PP (polypropylene) vinyl, PE (polyethylene) vinyl, HDPE (high density polyethylene) vinyl, LDPE (low density polyethylene) vinyl, NY (nylon) vinyl, CPP (cast polypropylene) vinyl, PU (polyurethane) vinyl, PVC (polyvinyl chloride) vinyl, and TPU (thermal polyurethane). Furthermore, when the barrier layer 300 is made of TPU, it can further increase the durability of the cosmetic puff by strengthening the adhesive force with other components.

[0044] That is, the pumping barrier film (300) is flexible and fluid, and completely blocks air penetration between the upper and lower layers.

[0045] Under this premise, the cosmetic puff 1000 according to one embodiment of the present invention differs from Prior Art Document 2 in that, as described above, the barrier layer 300 is always formed in contact with the first urethane foam layer 200, preventing the formation of air cells to which the cosmetic material adheres, thereby reducing the cushioning or shock-absorbing feeling.

[0046] Therefore, the cosmetic puff 1000 according to this embodiment is characterized in that an open post (250) having a set width in a direction perpendicular to the use surface or gripping surface is formed in the first urethane foam layer 200. The open post (250) is formed to penetrate the first urethane foam layer 200 without providing a separate space, and can play the role of a so-called air cell.

[0047] That is, the open pillar 250 is formed so that one end contacts the use surface layer 100 and the other end contacts the barrier layer 300. In this case, the thickness of the first urethane foam layer 200 is formed to be larger than the thickness of the use surface layer 100, but the height of the open pillar 250 is formed to correspond to the thickness of the first urethane foam layer 200. Also, the width of the open pillar 250 is formed to correspond to the thickness of the use surface layer 100, so that the cosmetic absorbed by the first urethane foam layer 200 is discharged very smoothly to the use surface layer 100. That is, the open pillar 250 not only enhances the cushioning feeling, but also further enhances the absorption and discharge of the cosmetic. Meanwhile, the first urethane foam layer 200 may be formed in an open cell structure, but when the width of the open pillar 250 is formed wider, it may be preferable to adopt a structure in which open cells and closed cells are mixed.

[0048] Meanwhile, the gripping surface layer 500 is attached to the upper side of the second urethane foam layer 400, and is used in a form in which a handle band (not shown) is attached so that the user can easily hold it as it is or hang his / her fingers on it. Here, the gripping surface layer 500 is formed to be held by the user's hand, and urethane, TPU, Jones, and other synthetic leathers can be used so that the user's hands are not contaminated by cosmetics. Furthermore, when using such synthetic leather, a design element can be added to express a more refined decorative aesthetic through the outer layer, and a product trademark can be engraved to provide advertising and public relations effects.

[0049] Thus, it will be understood by those skilled in the art to which the present invention pertains that the present invention can be embodied in other specific forms without changing the technical spirit or essential characteristics thereof.

[0050] In addition, although the present specification and drawings disclose preferred embodiments of the present invention, specific terms are used, but these terms are used in a general sense to simply explain the technical contents of the present invention and to aid in the understanding of the invention, and are not intended to limit the scope of the present invention. In addition to the embodiments disclosed in the present specification, it is obvious to a person having ordinary knowledge in the technical field to which the present invention pertains that other modifications based on the technical concept of the present invention can be implemented.
