Definitions

  • the present invention relates to a method of manufacturing a double cosmetic container, and more particularly, to a method of manufacturing a double cosmetic container, in which a variety of pattern portions formed on the outer surface of an inner preform are inflated during blow molding so as to be projected in various patterns through an outer container To a method of manufacturing a dual cosmetic container.
  • the present invention forms a pattern on the inner container and integrally combines with the outer container, thereby preventing the forgery from occurring. It is also possible to produce differentiated products by marking the order identification mark including the logo and the initial To a method of manufacturing a dual cosmetic container.

Description

이중 화장품용기의 제조방법
본 발명은 이중 화장품용기의 제조방법에 관한 것으로, 더욱 상세하게는 내측프리폼의 외측 면에 형성된 다양한 형상의 패턴부가 블로우 성형시 팽창하여 일체로 결합된 외측용기를 통해 다채로운 무늬로 투영될 수 있도록 한 이중 화장품용기의 제조방법에 관한 것이다.
또한, 본 발명은 내측용기에 패턴을 형성하여 외측용기와 일체로 결합하므로 위조를 원천적으로 방지할 수 있고, 로고 및 이니셜을 포함하는 주문자 식별표시를 각인하여 각 주문자 별로 차별성 있는 제품의 생산이 가능한 이중 화장품용기의 제조방법에 관한 것이다.
일반적으로 화장품용기는 본체의 내측에 화장품의 내용물이 충진되며, 본체의 입구에는 나사식 또는 돌기에 의해 착탈식으로 뚜껑이 결합되어 내용물의 인출시 뚜껑을 분리하고 사용하도록 되어 있으며, 이러한 화장품용기는 그 외측에 제품명이나 제조사 상호 및 제품 이미지를 나타내는 도안 등을 인쇄하여 제품성 및 자사광고효과, 제품의 외적 미감을 제공하고 있다.
그러나 이러한 화장품 용기의 경우 취급상의 부주의로 인하여 외부의 충격에 의해 본체가 파손되는 문제점이 있었으며, 최근에는 등록특허공보 제10-1288797호에서와 같은 이중구조로 이루어진 화장품용기를 제안함으로써 외부충격에 의한 파손을 방지하였다.
이러한 종래의 이중 화장품용기는 대부분 내측용기와 외측용기를 각각 별도로 제작한 후 서로 결합되고, 이렇게 결합된 내측용기와 외측용기는 분리된 별개의 용기로 구성되어 그 사이에는 공간이 형성될 수밖에 없다.
따라서 외측용기의 내측 면에 별도의 코팅작업을 해야 하기 때문에 제조비용이 증가하고, 코팅을 위해 여러 가지 화학약품을 사용함으로써 생산방식이 친환경적이지 않다는 문제점이 있었다.
또한, 내측용기의 표면에 다양한 무늬를 형성하는 방식에 한계가 있어 화장품용기의 디자인적 가치를 높이지 못하여 소비자의 구매욕을 향상시키지 못하는 문제점이 있었다.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 내측용기의 외측 면에 다양한 형상의 문자, 패턴, 그림 등을 형성하여 외측용기를 통해 더욱 다채로운 무늬를 투영할 수 있도록 개선한 이중 화장품용기의 제조방법을 제공하는 데 목적이 있다.
또한, 본 발명은 내측용기와 외측용기를 밀착 성형하여 외측용기 내측 면의 코팅작업을 생략할 수 있는 이중 화장품용기의 제조방법을 제공함에 다른 목적이 있다.
또한, 본 발명은 패턴이 형성된 내측용기에 외측용기를 일체로 결합하는 방식으로 구현되어 위조를 원천적으로 방지할 수 있고, 로고 및 이니셜을 포함하는 주문자 식별표시를 각인하여 각 주문자 별로 차별성 있는 제품의 생산이 가능한 이중 화장품용기의 제조방법을 제공함에 또 다른 목적이 있다.
본 발명의 일 측면에 따르면, 성형공간(11)이 형성되고 내주면에 패턴성형부(12a)가 구비된 내측프리폼 상부금형(10) 및 토출부 성형공간(15)이 구비된 내측프리폼 하부금형(14)을 이용하여 외측면에 문자, 그림, 도형, 나선형 홈 중 어느 하나 이상으로 이루어진 다양한 형상의 패턴부(42)가 형성된 내측프리폼(40)(40a)을 성형하는 단계; 상기 내측프리폼(40)(40a)을 외측프리폼 상부금형(20)의 성형공간(21)에 삽입하고 상기 내측프리폼(40)(40a)의 토출부(41)를 외측프리폼 하부금형(23)에 고정한 후 상기 외측프리폼 상부금형(20)의 성형공간(21)에 액상의 원료를 투입하여 상기 패턴부(42)가 형성된 상기 내측프리폼(40)(40a)의 외측면에 외측프리폼(50)을 밀착 성형하는 단계; 및 밀착 성형된 상기 내측프리폼(40)(40a) 및 상기 외측프리폼(50)을 동시에 가열한 후 블로우 성형금형(30)의 성형공간(31)에 삽입하고 상기 내측프리폼(40)(40a)의 토출부(41)에 블로우관(32)을 삽입한 후 블로우 성형에 의해 동시에 상기 내측프리폼(40)(40a) 및 상기 외측프리폼(50)을 확장하여 내측용기(100)(100a)와 외측용기(200)가 밀착된 이중 화장품용기를 성형하는 단계를 포함하는 이중 화장품용기의 제조방법이 제공될 수 있다.
본 발명의 실시예는 내측프리폼의 외측 면에 다양한 형상의 문자, 패턴, 그림 등의 패턴부를 형성하고, 블로우 성형에 의해 팽창시킴으로써 내측용기와 밀착 결합되는 외측용기를 통해 투영되어 다양한 미적 연출이 가능해지고, 이로 인해 화장품용기의 디자인적 가치를 높여 제품의 고급화를 추구할 수 있으며, 소비자로 하여금 구매욕을 증가시키는 효과가 있다.
또한, 본 발명의 실시예는 내측용기와 외측용기가 밀착 결합되어 성형됨으로써 내측용기의 외측 면이 외측용기에 의해 코팅이 되는 효과를 갖게 되어 기존의 코팅작업을 생략할 수 있게 되고, 이에 따라 공정이 단축되며, 코팅에 필요한 화학약품을 사용하진 않아도 되기 때문에 친환경적인 방식에 의해 화장품용기를 생산할 수 있는 장점이 있다.
또한, 본 발명의 실시예는 내측용기의 외측면에 형성된 패턴이 외측용기의 내측면과 밀착 결합하는 방식이므로, 외부에서 후가공을 통해 제작이 불가능하여 위조를 원천적으로 방지할 수 있고, 로고 및 이니셜을 포함하는 주문자 식별표시를 각인하여 각 주문자 별로 차별성 있는 제품의 생산이 가능한 효과가 있다.

본 발명의 바람직한 실시 예를 첨부된 도면을 통해 상세히 설명한다.
본 발명의 이중 화장품용기를 제작하기 위해서는 도 1에서 나타낸 바와 같은 내측프리폼 상부금형(10) 및 내측프리폼 하부금형(14)를 이용하여 외측 면에 다양한 형상의 패턴부(42)가 형성된 내측프리폼(40)을 먼저 성형하게 된다.
상기 내측프리폼 상부금형(10)의 내측에는 내측프리폼(40)의 형상과 대응하는 성형공간(11)이 형성되어 있으며, 상기 내측프리폼 상부금형(10)의 일측에는 패턴성형부(12a)가 구비된 체인지 코어(12)가 착탈가능하게 결합되며, 상기 내측프리폼(40)(40a)의 외측 면에는 상기 패턴성형부(12a)에 의해 문자, 그림 중 어느 하나 이상으로 이루어진 패턴부(42)가 요철(凹凸)에 의해 형성된다. ,
상기 패턴부(42)는 문자, 그림, 도형 등의 다양한 형상으로 형성할 수 있으며, 이를 성형하기 위한 패턴성형부(12a)는 체인지 코어(12)의 내주면에 요철(凹凸)을 형성하게 되는데, 상기 요철은 금형의 표면을 부식시켜 표면의 거칠기를 조절하는 부식처리 방식으로 구현되는 것이 바람직하다.
본 발명에서는 다양한 패턴을 자유롭게 신속하게 변경할 수 있도록, 체인지 코어(12)를 적용하였으며, 상기 상부금형(10)에 체인지 코어(12)를 고정하는 구성은 금형업계의 일반적 구조이므로, 이하 상세한 설명은 생략한다.
따라서, 패턴(문자와 도형을 포함)을 이루는 요철의 높이와 폭의 크기를 적절히 조절함으로써 추후 블로우 성형에 의해 팽창하는 패턴부(42)가 일그러지지 않고 원모습대로 확대될 수 있으며, 이러한 미세한 조절에 의해 성형된 제품은 소비자로 하여금 진품과 모조품을 용이하게 구별할 수 있으므로, 위조방지에 특장점이 있다.
본 발명의 일 실시예로, 상기 패턴부(42)는 요철(凹凸)에 의해 문자 또는 그림으로 이루어진 일정한 형상을 이루고, 블로우 성형시의 연신량에 따라 패턴부(42)의 높이와 폭의 크기를 조절하여 팽창시 패턴부(42)의 일그러짐을 방지하게 되며, 블로우 성형에 의해 팽창되면서 스모그 처리한 무늬로 구현된다.
본 발명의 내측프리폼(40)과 외측프리폼(50)은 블로우 성형시 높이방향으로는 10% 이내만 팽창하고, 폭 방향으로는 50%까지 팽창하므로, 방향별 연신량에 따라 패턴부(42)의 크기를 다르게 조절하여 작업해야 한다. (예를 들어, 팽창을 고려하여 패턴의 폭을 작게)
또한, 상기 패턴부(42)에는 블로우 성형시 전체 형상이 명확하게 나타날 수 있도록 외곽라인을 따라 깊이가 강화된 보강부(42a)가 형성되는 것이 바람직하다.
본 발명의 다른 실시예로, 상기 패턴부(42)를 잉크로 형성할 수도 있으며, 이때도 블로우 성형시의 연신율을 감안하여 잉크의 두께를 조절해야 한다.
한편, 상기 내측프리폼 상부금형(10)의 상측에는 상기 성형공간(11)과 연통되어 내측으로 액상의 합성수지 원료를 투입할 수 있도록 원료투입구(13)가 형성되어 있으며, 상기 내측프리폼 하부금형(14)에는 내측프리폼(40)의 토출부(41)와 대응하는 형상의 토출부 성형공간(15)이 형성되어 있으며, 상기 토출부 성형공간(15)과 성형공간(11)에는 핀(16)이 삽입된다.
따라서 원료투입구(13)를 통해 유입된 액상의 원료는 핀(16)에 의해 내측프리폼(40)의 내측에 공간을 형성하게 되며, 내측프리폼(40)의 외측 면에는 체인지 코어(12)의 패턴성형부(12a)에 의해 패턴부(42)가 성형된다.
이렇게 성형된 내측프리폼(40)의 외측에는 도 2에서 나타낸 바와 같이 외측프리폼(50)이 밀착 결합되는데, 상기 외측프리폼(50)을 성형하기 위해서는 내측프리폼(40)을 외측프리폼 상부금형(20)의 성형공간(21)에 삽입하고, 외측프리폼 하부금형(23)에 의해 상기 토출부(41)를 고정한다.
그리고 원료투입구(22)를 통해 액상의 원료를 투입하면 패턴부(42)가 형성된 내측프리폼(40)의 외측 면을 코팅하며 외측프리폼(50)이 밀착 성형된다.
상기 내측프리폼(40)과 외측프리폼(50)은 동종재질의 합성수지 또는 이종재질의 합성수지로 구성될 수 있고, 블로우 성형시 밀착 성형될 수 있도록 외측프리폼(50)에 비해 내측프리폼(40)의 용융점이 높은 것이 바람직하다.
이때, 상기 내측프리폼(40)은 다양한 색상을 갖는 합성수지로 구성할 수 있으며, 상기 외측프리폼(50)은 투명 또는 반투명의 재질로 구성함으로써 내측프리폼(40)의 색상이 외측프리폼(50)을 통해 외부로 투영될 수 있도록 구성하는 것이 바람직하다.
본 발명의 일 실시예로 내측프리폼(40)은 에코젠을 사용하고, 외측프리폼(50)은 PETG 재질을 사용하였으며, 이외에 용융점이 낮고, 내화학성이 우수한 PE, PP를 사용할 수도 있다.
이렇게 결합된 프리폼은 도 3에서 나타낸 바와 같이 좌우로 구성된 블로우 성형금형(30)의 성형공간(31)에 삽입하고, 상기 토출부(41)의 내측에 블로우관(32)을 삽입하여 공기를 주입함으로써 가열된 프리폼이 도 4에서 나타낸 바와 같이 동시에 확장하게 되어 화장품의 내용물이 채워지는 공간을 형성하면서 상기 성형공간(31)에 대응하는 형상의 외형을 가지며 내측용기(100)와 외측용기(200)로 구성된 이중 화장품용기가 성형된다.
이와 같은 과정을 순차적으로 거치며 성형된 본 발명의 이중 화장품용기는 도 5에서 나타낸 바와 같이 내측용기(100)과 외측용기(200)가 밀착 결합되어 성형됨으로써 다양한 형상의 패턴부(42)가 투명 또는 반투명의 외측용기(200)에 의해 은은한 색감에 의한 이미지의 연출로 인해 제품의 고급화를 추구할 수 있으며, 패턴성형부(12a)의 표면 부식처리에 의해 마치 유리에 스모그 처리를 한 것과 같은 효과를 얻을 수 있다.
또한, 내측용기(100)의 외측 면을 외측용기(200)가 코팅하는 효과를 갖게 되어 기존의 외측용기의 내측 면에 코팅작업을 수행하는 과정을 생략할 수 있어 공정이 단축되고, 여러 화학약품을 이용한 코팅작업을 생략할 수 있어 친환경적인 방식에 의해 화장품용기를 생산할 수 있는 장점이 있다.
한편, 본 발명의 다른 실시예로, 좌우로 분리하여 제품을 인출하는 반파팅(half parting)금형으로 작업할 경우에는 보다 다양한 제품을 구현할 수도 있다.
즉, 도 6에서 나타낸 바와 같이 내측프리폼(40a)의 외측 면에 나선형의 홈으로 이루어진 나선패턴부(43)를 형성할 수도 있는데, 이때는 내측프리폼 상부금형(10a)의 패턴성형부(12a)를 나선패턴부(43)의 형상과 대응하도록 형성하면 된다.
그리고 외측프리폼(50)의 결합과 블로우 성형의 과정을 거치면 도 7에서 나타낸 바와 같이 내측용기(100a)의 나선패턴부(43)가 외측용기(200)를 통해 투영되는 이중 화장품용기를 성형할 수 있으며, 상기 나선패턴부(43)는 패턴성형부(12a)의 깊이 및 폭에 의해 다양한 형상으로 성형할 수 있다.
또한, 도 8 및 도 9에 도시된 바와 같이, 상기 내측프리폼 상부금형(10)에서 체인지 코어(12)가 결합되는 상하측의 내측면에는 내측으로 돌출형성된 팽창패턴성형부(17)가 구비되고, 상기 내측용기(100a)의 패턴부(42) 상하에는 팽창시 일그러짐을 방지하는 팽창보상부(44)가 형성될 수 있다.
따라서 본 발명은 내측프리폼(40)(40a)의 외측 면에 다양한 형상의 문자, 패턴, 그림 등의 패턴부(42)를 형성하고, 블로우 몰딩에 의해 팽창시킴으로써 내측용기(100)(100a)와 밀착 결합되는 외측용기(200)를 통해 투영되어 다양한 미적 연출이 가능해지고, 이로 인해 화장품용기의 디자인적 가치를 높여 제품의 고급화를 추구할 수 있으며, 소비자로 하여금 구매욕을 증가시키는 효과가 있다.
또한, 내측용기(100)(100a)와 외측용기(200)가 밀착 결합되어 성형됨으로써 내측용기(100)(100a)의 외측 면이 외측용기(200)에 의해 코팅이 되는 효과를 갖게 되어 기존의 코팅작업을 생략할 수 있게 되고, 이에 따라 공정이 단축되며, 코팅에 필요한 화학약품을 사용하진 않아도 되기 때문에 친환경적인 방식에 의해 화장품용기를 생산할 수 있는 장점이 있다.
