Description

Technical Field

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

Background Art

[0002] Cosmetics including an impregnating member in the form of a sponge having a cosmetic composition built in dispersed open pores inside are widely used. Such cosmetics with a built-in sponge can easily discharge the cosmetic, which is the content, by mechanical pressure, and the discharged cosmetic may be used by applying it to a skin with a makeup tool such as a puff.

[0003] However, since the sponge itself has a plain outer shape, it is necessary to enhance the aesthetics, and there have been attempts to engrave a predetermined pattern on the surface of the sponge in order to facilitate the discharge characteristics of the cosmetic. For example, Korean Registered Patent No. 10-1566803 attempts to achieve uniform discharge of the content by pressing the surface of the sponge with a heated mold having an intaglio and relief pattern and engraving the opposite pattern on the surface.

[0004] However, the intaglio and relief pattern formed by such a conventional heat-pressing method is necessarily pressed while the surface sponge is melted or deformed, so that the open-cell or reticulated pore structure and cell structure are collapsed, making it difficult to smoothly discharge the content when puff-pressing.

[0005] On the other hand, in order to solve such problems, a laser marking method for forming a surface pattern by a laser beam has been proposed for the purpose of minimizing deformation of the pore structure for easy discharge of the cosmetic, but still, there are problems that deformation occurs at the processing site due to laser heat and the processing time for laser marking is also long.

Modes for Carrying Out the Invention

[0025] Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the drawings.

[0026] FIG. 1 is a schematic diagram showing a cosmetic according to an embodiment of the present invention.

[0027] As shown in the figure, the cosmetic 10 includes a container body 11 for accommodating a liquid cosmetic. A laminated impregnating material 100 for impregnating the liquid cosmetic is accommodated in the container body 11. The cosmetic may include an inner lid 13 and / or an outer lid 15 for preventing leakage of the liquid cosmetic from the laminated impregnating material 100. Further, although not shown, a fixture for fixing the impregnating material may be further provided to prevent detachment of the impregnating material. This will be described later.

[0028] FIG. 2 is an exploded perspective view schematically showing the appearance of a laminated impregnating material according to an embodiment of the present invention.

[0029] Referring to Figure 2, the laminated impregnating material 100 is composed of a laminate of a first block 110 and a second block 120.

[0030] In the present invention, the first block 110 may be embodied in a foamed synthetic resin. The foamed pores inside the first block 110 are connected to each other to form open channels. The pore structure of the first block 110 may be an open-cell foam or a mesh foam. Here, a mesh foam refers to a foam in which the sponge has a mesh structure, but the cell walls are open. For example, in the present invention, the number of pores per inch (ppi) of the sponge 110 may be 30 to 200 or 70 to 200.

[0031] In the present invention, various synthetic resins may be used for the material of the first block 110, such as polyether, polyester, polyurethane, PVA (polyvinyl alcohol), PE (polyethylene), EVA (ethylene vinyl acetate), ABS (acrylonitrile butadiene styrene), or synthetic rubber.

[0032] As an example, the polyurethane may be a polyurethane manufactured using polyether polyols, polyester polyols, mixtures thereof, or copolymers thereof as raw materials, and the synthetic rubber may be at least one rubber selected from the group consisting of SBR (styrene-butadiene rubber), BR (butadiene rubber), NR (natural rubber), and NBR (acrylonitrile-butadiene rubber).

[0033] On the other hand, a second block 120 is laminated on the first block 110. The second block 120 may be embodied in a foamed synthetic resin as described above, but the present invention is not limited thereto, and it may also be embodied in a woven fabric or nonwoven fabric.

[0034] The second block 120 is provided with an incision pattern 122 that forms a surface pattern of the laminated impregnating material. In the present invention, the incision pattern 122 may be realized by extending a through-slit that penetrates the second block in the thickness direction. That is, in the present invention, the incision pattern may correspond to a closed curve region defined by the through-slit. When the processed block section within the closed curve region formed by the through-slit is removed, the remaining portion remains as a single unit without being separated.

[0035] Such through-slits can be easily formed with non-heated mechanical tools such as blades, and no damage or deformation occurs to the material of the block during the formation of the through-slits.

[0036] Figure 3 is a schematic diagram showing an example of a cross-section of the laminated impregnating material shown in Figure 1.

[0037] Referring to Figure 3, an adhesive layer 130 is formed between the first block 110 and the second block 120.

[0038] In the present invention, various materials may be used for the adhesive layer 130. In the present invention, epoxy resin, acrylic resin, polyurethane resin, synthetic rubber adhesive, etc. may be used as the adhesive for forming the adhesive layer 130. Preferably, in the present invention, a water-soluble polyurethane resin may be used as the adhesive.

[0039] In one embodiment of the present invention, the adhesive layer 130 may be formed on one surface of at least one of the first block 110 and the second block 120, on the outer side of the incision pattern of the second block. In one embodiment, the adhesive layer 130 may be formed on one surface of the first block 110 at a location corresponding to the outer portion of the incision pattern of the second block. In another embodiment, the adhesive layer 130 may be formed on one surface of the second block 120 at a location corresponding to the outer portion of the incision pattern of the second block. In yet another embodiment, the adhesive layer 130 may be formed on one surface of the first block 110 and one surface of the second block 120 at locations corresponding to the outer portion of the incision pattern of the second block.

[0040] In the present invention, it is preferable that the adhesive layer 130 is formed only on the outside of the incision pattern of the second block (outside the slit closed curve region). When the adhesive layer is arranged in this manner, the liquid cosmetic composition moves through the incision pattern, making it easier for the cosmetic to move from the first block to the second block or vice versa. This can facilitate the filling of the cosmetic composition into the laminated impregnating material and the discharge of the cosmetic impregnating material from the laminated impregnating material.

[0041] When an incision pattern 122 is placed in the center of the second block 120 and an adhesive layer is placed outside the incision pattern, the following advantages may be obtained. As mentioned above, in the present invention, the inner wall of the incision pattern is formed without damage or deformation, so the porosity structure maintains its original open-fore structure. Therefore, when a user pressurizes the center of the upper surface of the laminated impregnating material 100 with a tool such as a puff, the liquid cosmetic impregnated inside the first block can be easily transferred to the second block through the central incision pattern. Thus, despite the presence of adhesive, the cosmetic can be continuously discharged.

[0042] More specifically, the adhesive layer 130 may be positioned along the outer circumference of the second block. For example, the adhesive layer 130 may be ring-shaped and extend along the outer circumference of the second block outside the incision pattern of the second block. Such a structure allows the adhesive to move through the non-adhesive area in the region outside the incision pattern of the second block.

[0043] The present invention has described a case in which the first block 110 and the second block 120 have the same two-dimensional shape defined by the same width and length, but the present invention is not limited thereto. Since the blocks constituting the laminated structure are separate entities, they may have different sizes from each other. For example, the second block 120 may have a smaller width or length than the first block 110, and vice versa.

[0044] Furthermore, while a laminated impregnating material composed of two blocks has been described with reference to Figures 2 and 3, the present invention is by no means limited thereto, and one or more intermediate blocks may be sandwiched between the first and second blocks or provided below the second block. In this case, the intermediate block may be embodied in foamed synthetic resin, woven fabric, nonwoven fabric, or the like.

[0045] Figures 4(a) and 4(b) show an example of a cosmetic product containing an impregnating material according to one embodiment of the present invention. Figure 4(a) is a schematic diagram showing the disassembled state of the cosmetic product, and Figure 4(b) is a schematic diagram showing the assembled state.

[0046] Referring to Figure 4, the laminated impregnating material 100 is housed on a container body 11 that contains the impregnating material. An impregnating material fixing device 17 having an opening 19 in the center is attached to the laminated impregnating material 100 to prevent the laminated impregnating material from detaching or separating.

[0047] <Example of experiment>

[0048] We conducted an experiment to measure the discharge characteristics of laminated impregnated materials laminated without adhesive and laminated impregnated materials coated with adhesive.

[0049] Two types of laminated impregnating material test specimens were prepared: one made by laminating two polyurethane sponges without adhesive, and another made by bonding two polyurethane sponges together with adhesive. The adhesive was applied along the edges of the sponges. After placing each impregnating material test specimen, which was soaked in cosmetic, into a container, a puff was placed on top of the sponge, and the amount of contents picked up by the puff was compared using a hardness tester with the same force, thereby comparing the amount of contents dispensed by each laminated impregnating material. Figure 5 is a photograph of the experimental setup. At this time, approximately the same amount of contents was soaked into each impregnating material test specimen.

[0050] [Table 1]

[0051] Table 1 shows that the amount of contents discharged from impregnated materials laminated with adhesive is similar to that of impregnated materials laminated without adhesive.

[0052] The lamination and bonding of the first and second blocks with adhesive have been described above, but in the present invention, the laminate may be embodied by other methods. For example, the laminate can be bonded by forming an edge portion by pressing the area near the edge of the laminate impregnating material using a method such as ultrasonic heating. In this case, the laminate impregnating material may have a lens shape that bulges upward and downward.

[0053] Furthermore, while the present invention has been described in detail with reference to embodiments, the above description is illustrative and does not limit the present invention. It should be considered that the scope of the present invention is such that any person with ordinary skill in the art to which the invention pertains can make various modifications without departing from the attached claims and the gist of the invention. [Industrial applicability]
