Abstract

The present invention relates to a double cosmetic container which has an inner container and an outer container formed simultaneously and integrally by means of blow molding, and a method for manufacturing same. Manufacturing procedures for an existing double cosmetic container not only are inconvenient but also require a separate coating work for the inner side of an outer container. Therefore, the manufacturing cost increases and the manufacturing method is not environmentally friendly since various chemicals are used for the coating. For a solution to the problem, the present invention provides a double cosmetic container having an outer container formed on the outer side of an inner container in which cosmetic contents are filled. The inner container and the outer container are integrally formed by means of simultaneously heating an inner preform and an outer preform, which comprise the same synthetic resin material, so as to have a common melting point, and simultaneously expanding same by means of blow molding. Therefore, since the present invention has the inner container and the outer container integrally attached and formed, the inner container plays the role of the coating for the inner side of the outer container and thus a traditional coating work can be omitted. Therefore, procedures are shortened and a cosmetic container can be manufactured in an environmentally-friendly way since chemicals for the coating are not required.

이렇게 히팅장치를 통과하여 가열된 프리폼은 블로우 몰딩단계(S40)에서 공기의 압력에 의해 동시에 확장됨으로써 내측용기(10)와 외측용기(20)가 일체를 이루는 이중 화장품용기를 성형하게 된다.The preform heated through the heating device is expanded at the same time by the pressure of air in the blow molding step (S40), thereby forming a double cosmetic container in which the inner container 10 and the outer container 20 are integrated.
상기 블로우 몰딩단계(S40)에서는 도 7에서 나타낸 바와 같은 블로우 성형금형(50)을 이용하여 가열된 프리폼을 일체화된 이중 화장품용기로 성형한다.In the blow molding step (S40), the heated preform is molded into an integrated double cosmetic container using the blow molding mold 50 as shown in FIG. 7.
상기 블로우 성형금형(50)의 내측에는 성형하고자 하는 이중 화장품용기의 형상과 대응하는 성형공간(52)이 형성되어 있으며, 상측에는 프리폼의 내측 공간과 연통되는 블로우홀(51)이 형성되어 있다.Inside the blow molding mold 50, a molding space 52 corresponding to the shape of the double cosmetic container to be molded is formed, and a blow hole 51 communicating with the inner space of the preform is formed on the upper side.
따라서 상기 블로우홀(51)을 통하여 적당한 압력의 공기를 주입함으로써 가열된 프리폼이 동시에 확장하게 되어 화장품의 내용물이 채워지는 내측의 공간이 형성되면서 성형공간(52)에 대응하는 형상의 외형을 갖는 이중 화장품용기가 성형된다.Accordingly, by injecting air of a suitable pressure through the blow hole 51, the heated preform expands at the same time to form an inner space in which the contents of the cosmetics are filled, and has a shape having a shape corresponding to the molding space 52. Cosmetic containers are molded.
이와 같은 제조과정을 순차적으로 거치며 성형된 본 발명의 이중 화장품용기는 내측용기(10)와 외측용기(20)가 일체로 결합되며 성형됨으로써 외측용기(20)의 내측 면을 내측용기(10)가 코팅하는 효과를 갖게 된다.The dual cosmetic container of the present invention formed by sequentially going through the manufacturing process as described above, the inner container 10 and the outer container 20 is integrally combined and molded to form an inner surface of the outer container 20 by the inner container 10. It will have a coating effect.
따라서 기존의 외측용기(20)의 내측 면에 코팅작업을 수행하는 과정이 생략되기 때문에 공정이 단축되고, 여러 화학약품을 이용한 코팅작업을 생략할 수 있어 친환경적인 방식에 의해 화장품용기를 생산할 수 있는 장점이 있다.Therefore, since the process of performing the coating operation on the inner surface of the existing outer container 20 is omitted, the process is shortened, and the coating operation using various chemicals can be omitted, and thus the cosmetic container can be produced in an environmentally friendly manner There is an advantage.
또한, 다양한 색상으로 원료로 이루어지는 내측용기(10)가 투명 또는 반투명의 외측용기(20)에 의해 일체로 코팅됨으로써 은은한 색감에 의한 이미지의 연출로 인해 제품의 고급화를 추구할 수 있다.In addition, since the inner container 10 made of a raw material in various colors is integrally coated by the transparent or semi-transparent outer container 20, it is possible to pursue a high quality product due to the production of an image with a subtle color.
상기와 같은 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.The present invention as described above is not limited to the above-described specific embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various changes without departing from the gist of the present invention as claimed in the claims. will be.
