Patent number: 10722020Abstract: A double wiping structure of a mascara wand provides an amount of mascara required to be applied to the eyelashes by causing a brush rod provided with a brush to be discharged along a ring member from a container so that mascara adhered to the brush rod is wiped using a first wiper and mascara adhered to the brush is wiped using a second wiper. The double wiping structure prevents mascara adhered to the brush from coming into contact with the inner surface of a wiper body and consequently prevents contamination of the inner surface of the wiper body due to the mascara by causing the ring member to be moved along the inner surface of the wiper body by pressure applied from the brush rod when the brush rod is introduced into and discharged from the container.Type: GrantFiled: October 22, 2018Date of Patent: July 28, 2020Assignee: CTK CO., LTD.Inventors: In Yong Chung, Jung Hun Jun

Patent number: 10537164Abstract: A cosmetic container with an anti-contamination function for a wiper is provided, where a ring member guides the introduction and discharge of a brush while being moved along the inner surface of a wiper by the pressure applied from a brush rod when the brush rod is introduced into and discharged from a cosmetic container. Thereby, it is possible to prevent the inner surface of the wiper from being contaminated by the contents such as mascara adhered to the brush and to ensure simplified use of the contents such as mascara. Further, since the inner surface of the wiper is not contaminated by the contents such as mascara, it is possible to ensure easy application of the contents such as mascara, which is adhered to the brush passing through the wiper.Type: GrantFiled: October 22, 2018Date of Patent: January 21, 2020Assignee: CTK CO., LTD.Inventors: In Yong Chung, Jung Hun Jun

Patent number: 9930952Abstract: Disclosed herein is a compact type of airtight cosmetic container. A shoulder cap (40) to which a mesh is coupled and a puff storage cap (50) which stores a puff are successively placed onto and coupled to a medial body (30) which contains a cosmetic therein. The shoulder cap and the puff storage cap can be airtightly coupled to the medial body by a sealing member (51) provided under the puff storage cap and a sealing ring (43) provided in the lower surface of the shoulder cap. A pressurizing means pressurizes the puff storage cap onto the medial body such that the sealing member and the sealing ring are compressed, whereby the sealability of the cosmetic container can be enhanced so that leakage of powder or a cosmetic change attributable to water evaporation can be reliably prevented.Type: GrantFiled: August 6, 2013Date of Patent: April 3, 2018Assignee: CTK CO., LTD.Inventor: Jin Woo Kim

Patent number: 9717317Abstract: Disclosed herein are capsule cosmetics and a manufacturing method thereof. This invention uses a one-piece type capsule container. After a liquid cosmetic material and a porous impregnation member are put into the container to manufacture cosmetics, the container is sealed by a sealing member, so that the porous impregnation member is naturally impregnated with the liquid cosmetic material. This allows the loading or impregnation of the liquid cosmetic material to be rapidly, easily, and simply realized, thus reducing manufacturing cost of the capsule cosmetics. As a result, this invention can afford inexpensive and high-quality products to consumers.Type: GrantFiled: April 25, 2014Date of Patent: August 1, 2017Assignee: CTK CO., LTDInventors: Jin Woo Kim, In Yong Chung

Publication number: 20140231304Abstract: Provided is a cosmetic case having a sealing function which prevents a gap from being formed between a main body and a cover, thus preventing cosmetics from being contaminated during a process of distribution. In the cosmetic case, a suction member can be reliably attached to the main body by means of suction force so that a gap is prevented from being formed therebetween. Therefore, cosmetics contained in the main body can be prevented from being contaminated during a process of distribution, and the weight of cosmetics can be maintained. Furthermore, when the user presses a button member, a cover opens and, simultaneously, the suction force of the suction member is removed, thus allowing the user to easily open the cover and suction cover unit.Type: ApplicationFiled: December 3, 2013Publication date: August 21, 2014Applicants: CTK CO., LTD.Inventor: Chung-Bae LEE
