본 발명은 용기부와 네크부가 한 번의 공정으로 성형되던 화장품 용기를 제조할 때 용기부와 네크부를 별도로 사출성형한 후 이를 초음파 용착함으로써 매끄러운 표면과 미려한 디자인의 화장품 용기를 얻을 수 있는 사출성형 화장품 용기 및 그 제조방법에 관한 것이다.The present invention is an injection molded cosmetic container which can obtain a cosmetic container with a smooth surface and beautiful design by ultrasonically welding the container part and the neck part after injection molding separately when manufacturing the cosmetic container in which the container part and the neck part were molded in one process. And to a method for producing the same.

일반적으로 아이라이너(eyeliner), 마스카라와 같은 여성용 눈썹 화장품의 구성은 뚜껑과 일체로 연설된 화장솔과 화장액이 담겨진 용기가 구비되어 화장솔은 상기 용기내부로 입출되며 뚜껑은 손잡이 구실을 하면서 용기의 네크부에 나착되는 것으로, 용기부와 네크부로 구분되는 제품특성상 이를 단 한번의 공정만으로 성형할 수 있는 불기(blowing) 공법을 사용하고 있다.Generally, the composition of women's eyebrow cosmetics, such as eyeliner and mascara, is provided with a cosmetic brush and a container filled with a cosmetic liquid, which is integrated with the lid, and the cosmetic brush enters the inside of the container and the lid serves as a handle and the neck of the container. It is attached to the part, it uses a blowing method that can be molded in a single process due to the characteristics of the product divided into the container portion and the neck portion.

그러나, 불기공법의 경우 단 한번의 블로잉 공정을 통하여 용기가 제조됨으로 외부여건에 따라 제품형상이 일정하지 않게 성형되며, 제품의 표면이 거칠어지거나 전체적인 균형이 맞지 않는 등 최초 디자인된 형성과 같은 미려한 디자인을 얻을 수 없었으며 따라서 완성된 화장품의 품질을 떨어뜨리는 한 요인으로 작용하고 있다.However, in the case of the non-porous method, since the container is manufactured through a single blowing process, the shape of the product is not uniformly formed according to the external conditions, and the design is beautiful, such as the roughness of the product or the overall balance is not balanced. It has not been possible to obtain this and thus acts as a factor in degrading the quality of the finished cosmetics.

또한 기능성 이외에도 장식적인 측면이 강하게 요구되는 여성용 화장품 용기의 특성상 여러 가지 형태의 용기 디자인이 요구되고 있으나 불기공법의 경우 오직 원통관형상으로만 성형됨으로 다양한 변화를 추구하는 현대 소비자의 욕구를 충족시키지 못하는 문제점이 발생하고 있다.In addition, various types of container designs are required due to the characteristics of women's cosmetics containers that require strong decorative aspects in addition to functionality. However, the non-porous method is molded only in the shape of a cylindrical tube, which does not satisfy the desire of modern consumers to pursue various changes. There is a problem.

본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 매끄럽고 부드러운 제품표면을 얻을 수 있는 사출성형공법을 이용하여 화장액이 충진되는 용기부와 뚜껑손잡이가 나착되는 네크부를 분할 사출성형하는 것으로 각 부분이 분리되는데 따르는 완전한 밀폐성 확보문제는 네크부에 밀폐패킹을 끼워서 용기부에 결합하고 이 결합부분을 초음파 용착하는 방법으로 해결함으로써 매끄러운 표면과 미려한 디자인의 화장품 용기를 얻을 수 있도록 하는데 그 목적이 있는 것이다.In order to solve the problems described above, the present invention divides each part into injection molding by dividing the neck of the container portion filled with the cosmetic liquid and the lid portion of the lid handle using the injection molding method to obtain a smooth and smooth product surface. The problem of ensuring a complete sealability is to provide a cosmetic container with a smooth surface and beautiful design by solving the sealing by inserting a sealing seal in the neck portion and joining the container portion by ultrasonic welding.

본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention.

첨부도면 제 1 도 및 제 2 도에 도시된 바와 같은 방법으로 용기부(1)와 네크부(2)를 사출성형하여 네크부(2)의 끼움부(3)에 밀폐패킹(5)을 끼워서 이 밀폐패킹(5)을 용기부(1)의 내부로 삽입하면서 네크부(2)의 받침판(4)과 용기부(1)의 저면이 밀착되도록 한 후 그 접합부(C)를 초음파 용착하게 되면 용기부(1)와 네크부(2)가 완전접합되면서 밀폐패킹(5)에 의하여 내부에 충진될 화장액이 절대로 누출되지 않는 밀폐구조가 형성됨으로 종래의 불기공법에서와 같은 일체성을 확보할 수 있는 것이다.The container part 1 and the neck part 2 are injection molded by the method as shown in FIGS. 1 and 2, and the sealing packing 5 is fitted to the fitting part 3 of the neck part 2. When the sealing packing 5 is inserted into the container part 1 while the base plate 4 of the neck part 2 is brought into close contact with the bottom surface of the container part 1, and then the joining part C is ultrasonically welded. As the container part 1 and the neck part 2 are completely joined together, a sealing structure is formed in which the cosmetic liquid to be filled inside is never leaked by the sealing packing 5, thereby ensuring the integrity as in the conventional non-porous method. It can be.

이와 같은 방법으로 제조되는 본 발명의 화장품 용기는 미리 디자인된 용기형상 그대로 제품을 얻을 수 있는 사출공법의 특성이 최대한 구현되어 완벽하고 매끄러운 표면의 사출물을 얻을 수 있을 뿐만 아니라 외부적인 요인이나 작업도중의 환경변화에 전혀 영향을 받지 않아 항상 일정하고 미려한 외관의 용기를 얻을 수 있는 것이다.The cosmetic container of the present invention manufactured by the above method can realize the injection molding method to obtain the product as it is pre-designed in the shape of the container as much as possible to obtain a perfect and smooth surface of the injection molding, as well as external factors and work in progress. It is not affected by environmental changes at all, so it is possible to obtain a container with a constant and beautiful appearance.

또한 첨부도면 제 5 도의 (가)(나)도에 도시된 바와 같이 다각형, 타원형 등 용기의 외형을 자유자재로 변형할 수 있는 사출금형의 특성을 살려 여러 가지 모양을 얻을 수 있는 것으로 종래에 제공된 불기공법에서는 전혀 기대할 수 없는 여성용 화장품 용기의 장식적 측면을 최대한 살려줌으로써 다양한 변화를 추구하는 현대 소비자의 욕구를 충족시키는 효과를 갖는 것이다.In addition, as shown in (a) (b) of FIG. 5 of the accompanying drawings, various shapes can be obtained by utilizing the characteristics of an injection mold that can freely modify the outer shape of a container such as a polygon or an oval. By making the most of the decorative side of women's cosmetics containers that cannot be expected at all, the method has the effect of satisfying the needs of modern consumers seeking various changes.

이상에서 나타나는 바와 같이 본 발명의 사출성형 화장품 용기 및 그 제조방법에 의하면 기존 불기공법으로 만들어진 화장품 용기의 최대단점인 껄끄럽고 세련되지 못한 표면상태, 원통관 형태로만 한정되었던 제품디자인, 최초 디자인된 외형과 다소 동떨어진 성형결과 등의 여러 가지 문제점을 일소할 수 있도록 사출성형공법을 채택하되 사출성형공법에서의 용기부와 네크부를 한 번의 공정으로 성형할 수 없는 결점을 해결하기 위해 양 부분을 각각 성형하고 이 부분들의 밀폐성을 확보하기 위해 밀폐패킹을 부가한 초음파 용착공정을 추가함으로써 최초 목적하는 바와 같이 세련된 외관과 다양한 디자인의 화장품 용기를 얻도록 하는 유용한 발명인 것이다.As shown above, according to the injection molded cosmetic container of the present invention and a method for manufacturing the same, a gritty and unsophisticated surface state, which is the biggest disadvantage of a cosmetic container made by a conventional non-porous method, a product design limited to a cylindrical tube shape, and the first designed appearance The injection molding method is adopted to eliminate various problems such as the molding result which is farther away from each other, but each part is molded to solve the drawback that the container part and the neck part cannot be molded in one step in the injection molding method. It is a useful invention to obtain a cosmetic container of a refined appearance and various designs as initially intended by adding an ultrasonic welding process with the addition of a sealed packing to ensure the sealing of these parts.
