Description

Technical Field

[0001] The present invention relates to a sponge for impregnating cosmetic materials, and more particularly to a sponge foam for impregnating cosmetic materials including the sponge for impregnating cosmetic materials, cosmetics including the sponge foam, and a method for manufacturing the same. Background Art

[0002] Cosmetics including a sponge-shaped impregnated member having a cosmetic composition embedded in open pores dispersed therein are widely used. Such a sponge-embedded cosmetic can easily discharge the cosmetic as the content by mechanical pressing, and the discharged cosmetic can be used in a manner of applying it to the skin by applying it to a cosmetic tool such as a puff.

[0003] However, the sponge itself has a plain appearance, so it is necessary to further highlight the appearance. In addition, in order to facilitate the discharge of cosmetic materials, attempts have been made to carve a predetermined pattern on the surface of the sponge. For example, in Korean Patent No. 10-1566803, an attempt is made to press the surface of the sponge with a heated mold formed with positive and negative patterns to carve patterns on the surface opposite to the positive and negative patterns, thereby promoting uniform discharge of the contents.

[0004] However, the yin-yang engraved patterns formed by the conventional heating and pressurizing method as described above will inevitably cause the sponge on the surface to melt or deform and be pressed, thereby causing the open cell or mesh pore structure and cell structure to be destroyed, making it difficult to discharge the contents smoothly when the puff is pressed.

[0005] On the other hand, in order to solve this problem, a laser marking method has been proposed, in which a surface pattern is formed using a laser beam to minimize the deformation of the pore structure to facilitate the discharge of cosmetics, but there are still problems such as deformation at the processing site due to laser heat and a long processing time required for laser marking.

[0032] Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the accompanying drawings.

[0033] Figure 1 This is a diagram schematically showing a cosmetic according to an embodiment of the present invention.

[0034] As shown in the figure, the cosmetic 10 has a container body 11 for containing a liquid cosmetic. A layered impregnating material 100 impregnated with a liquid cosmetic is contained in the container body 11. The cosmetic may include an inner cover 13 and / or an outer cover 15 for preventing the liquid cosmetic from leaking from the layered impregnating material 100. In addition, although not shown, in order to prevent the impregnating material from detaching, a fixing member for fixing the impregnating material may also be provided. This will be described separately later.

[0035] Figure 2 This is an exploded perspective view schematically showing the appearance of a layered impregnation material according to an embodiment of the present invention.

[0036] Reference Figure 2 The laminated impregnation material 100 is composed of a laminated body of a first block 110 and a second block 120 .

[0037] In the present invention, the first block 110 can be made of a foamed synthetic resin. The foamed pores inside the first block 110 are connected to each other in a manner of forming an open channel. The pore structure of the first block 110 can be an open cell foam or a reticular foam structure. Here, the reticular foam refers to a foam in which the sponge has a reticular structure and the cell walls are open. Exemplarily, in the present invention, the number of pores per inch (ppi) of the sponge 110 can be 30 to 200 or 70 to 200.

[0038] In the present invention, various synthetic resins can be used as the material of the first block 110. For example, polyether, polyester, polyurethane, PVA (polyvinyl alcohol), PE (polyethylene), EVA (ethylene vinyl acetate), ABS (acrylonitrile butadienestyrene) or synthetic rubber can be used.

[0039] For example, as the polyurethane, a polyurethane made from polyether polyol, polyester polyol, a mixture thereof or a copolymer thereof as a raw material can be used, and the synthetic rubber can use at least one rubber selected from the group consisting of SBR (styrene-butadiene rubber), BR (butadiene rubber), NR (natural rubber) and NBR (acrylonitrile-but adiene rubber).

[0040] On the other hand, a second block 120 is stacked on the first block 110. The second block 120 may be made of the aforementioned foamed synthetic resin, but the present invention is not limited thereto, and may also be made of fabric or non-woven fabric.

[0041] The second block 120 has a cut pattern 122 for forming a surface pattern of the laminated impregnation material. In the present invention, the cut pattern 122 can be realized by a through slit extending through the first block in the thickness direction. That is, in the present invention, the cut pattern can correspond to a closed curve area defined by the through slit. If the processed block piece in the closed curve area formed by the through slit is removed, the remaining part is formed into one piece without separation.

[0042] The through slits as described above can be easily formed using a non-heating mechanical tool such as a knife blade, and the material of the block will not be damaged or deformed when the through slits are formed.

[0043] Figure 3 It is schematically shown Figure 1 FIG. 1 is a diagram of an example of a cross section of a laminated impregnated material.

[0044] Reference Figure 3 , an adhesive layer 130 is formed between the first block 110 and the second block 120 .

[0045] In the present invention, various materials can be used for the adhesive layer 130. In the present invention, epoxy resin, acrylic resin, polyurethane resin, synthetic rubber adhesive, etc. can be used as the adhesive for forming the adhesive layer 130. Preferably, in the present invention, water-soluble polyurethane resin can be used as the adhesive.

[0046] In one embodiment of the present invention, the adhesive layer 130 may be formed on the outside of the cut pattern of the second block in one side of at least one of the first block 110 and the second block 120. As one embodiment, the adhesive layer 130 may be formed in a position corresponding to the outer portion of the cut pattern of the second block in one side of the first block 110. As another embodiment, the adhesive layer 130 may be formed in a position corresponding to the outer portion of the cut pattern of the second block in one side of the second block 120. As yet another embodiment, the adhesive layer 130 may be formed in a position corresponding to the outer portion of the cut pattern of the second block in one side of the first block 110 and one side of the second block 120.

[0047] In the present invention, preferably, the adhesive layer 130 is limited to the outside of the cut pattern of the second block (outside the slit closed curve area). If the adhesive layer is configured as described above, the liquid cosmetic composition moves through the cut pattern, so that the movement of the cosmetic from the first block to the second block or the opposite direction can be facilitated. Thus, the filling of the cosmetic composition into the stacked impregnated material and the discharge of the cosmetic impregnated material from the stacked impregnated material can be facilitated.

[0048] When the incision pattern 122 is arranged in the central part of the second block 120 and an adhesive layer is arranged outside the incision pattern, the following advantages can be obtained. As mentioned above, in the present invention, since the inner wall of the incision pattern is formed without damage or deformation, the pore structure still maintains the initial open pore structure. Therefore, if the user presses the center of the top surface of the laminated impregnated material 100 with a tool such as a puff, the liquid cosmetic impregnated in the first block can be easily transferred to the second block via the central incision pattern. Therefore, there is a structure that can continuously discharge the cosmetic even in the presence of an adhesive.

[0049] More specifically, the adhesive layer 130 may be arranged along the periphery of the second block. For example, the adhesive layer 130 may be in a ring shape extending along the periphery of the second block outside the cut pattern of the second block. This structure enables the adhesive to move through the adhesive non-forming area in the area outside the cut pattern of the second block.

[0050] In the above, in the present invention, the first block 110 and the second block 120 have the same two-dimensional shape defined by the same amplitude and width, but the present invention is not limited thereto. The plurality of blocks constituting the stacked structure are separate independent components and thus may have different sizes from each other. As an example, the second block 120 may have a smaller amplitude or width than the first block 110, or vice versa.

[0051] In addition, refer to Figure 2 and Figure 3 , the laminated impregnation material consisting of two blocks is described, but it is obvious that the present invention is not limited to this, and one or more intermediate blocks can be arranged between the first block and the second block or arranged at the bottom of the second block. In this case, the additional block can be realized by foamed synthetic resin, fabric, non-woven fabric, etc.

[0052] Figure 4 (a) and (b) are diagrams showing an example of a cosmetic including an impregnated material according to an embodiment of the present invention. Figure 4 (a) is a schematic diagram of the decomposition state of cosmetics. Figure 4 (b) is a schematic diagram of the assembled state.

[0053] Reference Figure 4 The container body 11 for containing the impregnating material contains the laminated impregnating material 100. The laminated impregnating material fixing member 17 having an opening 19 in the center is mounted on the laminated impregnating material 100, so as to prevent the laminated impregnating material from being separated or separated.

[0054] Modes for carrying out the invention

[0055] <Experimental example>

[0056] An experiment was conducted to measure the discharge characteristics of a laminated impregnated material laminated without an adhesive and a laminated impregnated material coated with an adhesive.

[0057] We prepared a laminated impregnated material sample in which two polyurethane sponges were laminated without an adhesive and a laminated impregnated material sample in which polyurethane sponges were bonded with an adhesive. We applied an adhesive near the edge of the sponge. After placing each impregnated material sample impregnated with cosmetic material in a container, we placed a puff on the sponge and compared the amount of content taken out of the puff after pressing it with the same force using a hardness tester, and compared the discharge amount of each laminated impregnated material. Figure 5 This is a photo of the experimental setup. At this time, almost the same amount of content was impregnated into each impregnation material sample.

[0058] [Table 1]

[0059]

[0060] From Table 1, it can be confirmed that the content discharge amount of the impregnated material laminated with the adhesive is similar to that of the impregnated material laminated without the adhesive.

[0061] In the above, the stacking of the first block and the second block and the merging based on the adhesive are described, but the stacked body in the present invention can also be realized in a different manner. For example, the edge of the stacked impregnated material can be pressed by ultrasonic heating or the like to form an edge portion, thereby achieving merging. In this case, the stacked impregnated material can have a lens shape that bulges upward and downward.

[0062] In addition, the present invention is described by the embodiments of the present invention, but the above description illustrates the present invention, and the present invention is not limited thereto. Without departing from the appended claims and the gist of the present invention, the scope of various modifications that can be performed by those skilled in the art should also be considered to belong to the scope of the present invention.
