Description

Technical Field

[0001] The present invention relates to a zero-waste environmentally friendly cosmetic and a manufacturing method thereof, and more particularly to a cosmetic in which a raw material applicable to cosmetics is used in a cosmetic container to replace plastic, and the remaining container portion after use can be reused. Background Art

[0002] Plastic waste generated by plastic used in cosmetic containers reaches 60,000 tons per year, of which more than 90% is garbage that cannot be reused. That is, it flows into the environment due to incineration or landfill, thus causing harm to the global environment. Therefore, efforts need to be made to explore the production of cosmetics that do not require plastic containers or the use of materials that can replace plastic used in cosmetic containers, for example, a method of making cosmetic containers that can be used with raw materials suitable for cosmetics or a method of reducing waste by reusing leftover containers after use.

[0003] For example, a cosmetic pen is composed of a core corresponding to the cosmetic material content and a body corresponding to the cosmetic material container (shell), and is a rod-type cosmetic tool that can be sharpened and used like a pencil. The cosmetic pen can be provided with various cosmetic materials such as eye shadow, eyebrow pencil, eyeliner, lipstick, lip liner and concealer as the core.

[0004] The main body (outer container) of a common cosmetic pen is made of wood or plastic. Like pencils, cosmetic pen main bodies made of wood generate dust during the processing of raw materials and use plasticizers or adhesives. In addition, deforestation can cause damage to the natural environment, such as accelerated desertification and destruction of ecosystems.

[0005] Therefore, it is necessary to develop cosmetics and a manufacturing method thereof that do not contain plastics and are environmentally friendly and can be cut and used. Summary of the invention

[0033] Hereinafter, the present invention will be described in more detail by giving examples. However, these examples are for illustrative purposes only and should not be construed as limiting the scope of the present invention.

[0034] One aspect of the present invention provides an environmentally friendly cosmetic.

[0035] The cosmetic may include: a main body having a specified width and length and extending in the length direction; and a core extending inside the main body along the length direction of the main body; and may also include a cover connected to either end of the main body.

[0036] The main body may be made of wax, and the core may contain a cosmetic material composition.

[0037] The cover may include one or more substances selected from the group consisting of wax, oil, cellulose, gelatin, paper, felt paper, and leather.

[0038] The length of the body portion may be 30 to 200 mm, and the width of the core portion may be 2 to 20 mm.

[0039] The body can use the remaining portion after using the wick as a cube candle. A cube candle is a cube-shaped candle placed in a candle heater for a cube candle. A candle heater is a tool that melts scented candles by generating heat from a light bulb to release fragrance. A candle heater for a cube candle is a tool that places a cube-shaped candle in a downwardly concave container and uses a light bulb in the container to heat the candle to melt the candle in the container to release fragrance.

[0040] The present invention uses the core portion equivalent to the content of the cosmetic material and uses the remaining body portion as a cube candle, thereby minimizing the generation of garbage, that is, containers discarded after using the cosmetic material.

[0041] Another aspect of the present invention provides a method for producing environmentally friendly cosmetics.

[0042] The manufacturing method may include: a core molding step of manufacturing a core molded body by cooling and demolding after filling a core composition in a first mold; and a main body molding step of molding a main body by cooling and demolding after filling a main body composition outside the core molded body with the core molded body inserted into a second mold. In the main body molding step, the main body composition may be filled to the same height as the core molded body or to a height higher than the core molded body.

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] Figure 1a 1 is a cross-sectional view schematically showing a cosmetic pen 100 as an example of the cosmetic of the present invention. Figure 1b is a diagram showing an example of the use of a cosmetic pen 100 manufactured according to an embodiment of the present invention, Figure 1a The end of the core is used to show the protruding state of the core.

[0045] Reference Figure 1a and Figure 1b The pen 100 includes a main body 110 and a core 120 .

[0046] As shown in the drawings, in the present invention, the main body 110 is a columnar molded body having a predetermined width W1 and a length L and being elongated in the longitudinal direction.

[0047] For example, although the main body 110 is shown as a cylindrical shape, the shape of the main body in the present invention is not limited thereto. For example, the main body 110 can be a multi-cornered column shape such as a four-cornered column, a six-cornered column, etc.

[0048] In the present invention, the length of the main body can be 30 to 200 mm. As a preferred specific example, the length of the main body of the present invention is preferably 30 mm or more, 50 mm or more, or 70 mm or more, and preferably 200 mm or less, 150 mm or less, or 100 mm or less. When the length of the main body is less than 30 mm, it is difficult to hold the pen or to sharpen it with a pencil sharpener because the pen is short, and when the length of the main body exceeds 200 mm, it is easy to break.

[0049] In the present invention, the core 120 has a width W2 smaller than the width W1 of the main body 110 and is a molded body of the cosmetic composition extending inside the main body 110 in the longitudinal direction of the main body 110. The core 120 may be a columnar molded body like the main body 110.

[0050] As shown in the figure, the core 120 is exposed at one end A of the two ends of the main body 110 of the present invention, whereas the core 120 at the other end B of the pen 100 may not be exposed. Figure 3 This will be described later.

[0051] This is to protect the core in the two-step filling method as an exemplary manufacturing method of the present invention described later and to minimize the pinholes that may be generated. However, the present invention is not limited thereto, and the pen of the present invention can of course be formed so that the core at both ends is completely exposed or the core is not exposed.

[0052] The width W2 of the core may be 2 to 20 mm. As a preferred specific example, the width W2 of the core of the present invention is preferably 2 mm or more, 5 mm or more, or 10 mm or more, and preferably 20 mm or less, 15 mm or less, or 12 mm or less. If the width W2 of the core is less than 2 mm, the pencil may break when being sharpened with a pencil sharpener, and if the width W2 of the core exceeds 20 mm, it is difficult to hold the pen in one hand for use.

[0053] Additionally, the present invention may further include a cover portion coupled to either end of the pen 100. The cover portion may be coupled to one end or the other end of the pen according to the usage state.

[0054] Figure 21 is a flowchart showing an example of a method for manufacturing a cosmetic brush according to an embodiment of the present invention.

[0055] Reference Figure 2 In the present invention, the pen 100 can be manufactured by a two-step molding method consisting of a core molding step S110 and a body molding step S120.

[0056] Specifically, in the core forming step S110, the core is formed by using a first mold. Then, a cosmetic pen having a core disposed inside the body can be manufactured by performing a body forming step S120 in which the body is formed outside the core forming body using a second mold.

[0057] Figure 3 (a) and (b) are diagrams schematically showing a first mold used in a core portion molding step and a second mold used in a body portion molding step, respectively.

[0058] Reference Figure 3 (a), in the present invention, the core 120 may be manufactured by a first mold 200 .

[0059] Specifically, the first mold 200 may be a mold in which the first filling part 220 is coupled to the upper part of the support part 210. To facilitate demolding, the first mold 200 may include a plate-shaped fixing part 230a to which a column 230b capable of fixing the molded core is coupled.

[0060] In the core molding step S110, the core composition may be filled into the first filling part 220 combined with the support part 210, and then cooled and demolded to manufacture the core molded body 240. The core molded body 240 is fixed to the column 230b of the fixing part 230, and can be demolded by lifting the fixing part 230. As another specific example, in a state where the core molded body 240 is fixed to the support part 210, the first filling part 220 may be separated from the support part 210 and removed from the core molded body for demolding.

[0061] Reference Figure 3 (b), in the present invention, the main body 110 can be manufactured by the second mold 300.

[0062] Specifically, the second mold 300 may be a mold in which the second filling part 320 is combined with the upper part of the support part 310. To facilitate demolding, the second mold 300 may include a plate-shaped fixing part 330a, and a column 330b capable of fixing the formed body part is combined with the fixing part 230.

[0063] The second filling part 320 may be a structure in which the lower plate 320a and the upper plate 320b are combined, or may be a structure in which the lower plate 320a and the upper plate 320b are integrated. At this time, the height of the second filling part 320 is preferably equal to or higher than the height of the first filling part 220. After the height of the second filling part 320 is set to be higher than the core molded body, by filling the main body composition, a height difference G between the main body and the core as illustrated in Figure 1 can be formed.

[0064] In the main body molding step S120 , after the second filling part is combined with the support part 310 , the main body composition may be filled to the outside of the core molded body while the core molded body is inserted into the second filling part.

[0065] In the case of using the second filling unit 320 using the lower plate 320a and the upper plate 320b in combination, as shown in FIG. Figure 1a As shown, on the outer peripheral surface of the main body, the lower plate 320a and the upper plate 320b form a boundary line at the joint portion, and in the case of using the second filling part 320 in which the lower plate 320a and the upper plate 320b are integrated, as shown in FIG. Figure 1b As shown, the outer peripheral surface of the main body has a smooth surface and is aesthetically pleasing.

[0066] The filled main body composition can be cooled and then demolded to form the main body 340. The main body 340 is fixed to the column 330b of the fixing part 330 and can be demolded by lifting the fixing part 330. As another specific example, in a state where the main body 340 is fixed to the support part 310, the second filling part 320 can be demolded by separating it from the support part 310 and removing it from the main body.
