Description

이중 화장품용기{Dual cosmetic vessel}Dual cosmetic vessel

본 발명은 내측용기와 외측용기로 이루어진 이중 화장품 용기에 관한 것으로, 더욱 상세하게는 내측용기와 외측용기가 블로우 몰딩에 의해 동시에 일체로 성형되는 이중 화장품용기에 관한 것이다.The present invention relates to a double cosmetic container composed of an inner container and an outer container, and more particularly, to a double cosmetic container in which the inner container and the outer container are integrally molded simultaneously by blow molding.

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 자사광고 효과, 제품의 외적 미감을 제공하고 있다.In general, the cosmetic container is filled with the contents of cosmetics on the inside of the body, and the lid is detachably attached to the entrance of the body by screws or projections to separate and use the lid when taking out the contents. The product name, manufacturer's name, and a pattern representing the image of the product are printed on the outside to provide product characteristics, company advertisement effects, and external aesthetics of the product.

그러나 이러한 화장품 용기의 경우 취급상의 부주의로 인하여 외부의 충격에 의해 본체가 파손되는 문제점이 있었다.However, in the case of such a cosmetic container, there is a problem that the body is damaged by an external impact due to careless handling.

따라서 최근에는 등록특허공보 제10-1288797호에서와 같은 이중구조로 이루어진 화장품용기를 제안함으로써 외부충격에 의한 파손을 방지하였다.Therefore, recently, a cosmetic container made of a dual structure as in Patent Publication No. 10-1288797 has been proposed to prevent damage due to external impact.

이러한 종래의 이중 화장품용기는 대부분 내측용기와 외측용기를 각각 별도로 제작한 후 서로 결합하거나, 외측용기의 내측에 프리폼(preform)을 결합한 후 블로우 몰딩에 의해 내측용기를 형성하였다.In most of these conventional double cosmetic containers, the inner container and the outer container are separately manufactured and then combined with each other, or a preform is combined inside the outer container to form an inner container by blow molding.

이러한 이중 화장품용기는 제조공정이 매우 번거로울 뿐만 아니라, 이렇게 결합된 내측용기와 외측용기는 분리된 별개의 용기로 구성되어 그 사이에는 공간이 형성될 수밖에 없다. In addition to this, the manufacturing process of the double cosmetic container is very cumbersome, and the inner container and the outer container combined as described above are composed of separate containers, and a space is inevitably formed therebetween.

따라서 외측용기의 내측 면에 별도의 코팅작업을 해야하기 때문에 제조비용이 증가하고, 코팅을 위해 여러 가지 화학약품을 사용함으로써 생산방식이 친환경적이지 않다는 문제점이 있었다.Therefore, there is a problem that the manufacturing method is not environmentally friendly because the manufacturing cost increases because a separate coating operation is required on the inner surface of the outer container, and various chemicals are used for coating.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 블로우 몰딩에 의해 내측용기와 외측용기를 동시에 성형할 수 있는 이중 화장품용기를 제공하는데 목적이 있다.The present invention is to solve the above problems, and an object of the present invention is to provide a double cosmetic container capable of simultaneously molding the inner container and the outer container by blow molding.

또한, 본 발명의 다른 목적은 내측용기와 외측용기를 일체로 성형하여 외측용기 내측 면의 코팅작업을 생략할 수 있는 이중 화장품용기를 제공하는 데 있다.In addition, another object of the present invention is to provide a double cosmetic container that can be formed by integrally forming the inner container and the outer container to omit the coating operation on the inner surface of the outer container.

본 발명에 의한 이중 화장품용기는 내측에 화장품 내용물이 채워지는 내측용기의 외측에 외측용기가 형성된 이중 화장품용기에 있어서, 색상을 가진 합성수지로 이루어진 내측프리폼(10a)(Inner preform)의 외측에 투명 또는 반투명의 동일재질 합성수지로 이루어진 외측프리폼(20a)(Outer preform)을 인서트 몰딩하고, 내측프리폼(10a)과 외측프리폼(20a)을 히팅장치로 표면을 가열하여 서로 접하는 부위를 용융결합시킨 후, 블로우 몰딩에 의해 내측프리폼(10a)과 외측프리폼(20a)을 동시에 확장시켜, 내측프리폼(10a)에 의해 형성되는 내측용기(10)와 외측프리폼(20a)에 의해 형성되는 외측용기(20)의 사이에 공극이 발생하지 않도록 일체로 성형하여 구성되는 것을 그 기술적 특징으로 한다.The double cosmetic container according to the present invention is a double cosmetic container in which an outer container is formed on the outer side of an inner container in which cosmetic contents are filled on the inner side, and is transparent on the outer side of the inner preform 10a (Inner preform) made of synthetic resin having color. After insert molding the outer preform 20a (outer preform) made of the translucent same material synthetic resin, and heating the surfaces of the inner preform 10a and the outer preform 20a with a heating device, melt-bond the parts that are in contact with each other, and blow. Simultaneously expanding the inner preform 10a and the outer preform 20a by molding, between the inner container 10 formed by the inner preform 10a and the outer container 20 formed by the outer preform 20a. It is characterized by being formed by integrally forming so that no voids are generated.

본 발명에 따른 이중 화장품용기에 의하면, 내측용기와 외측용기가 일체로 결합되어 성형됨으로써 외측용기의 내측 면이 내측용기에 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.According to the double cosmetic container according to the present invention, the inner container and the outer container are integrally molded and formed, so that the inner surface of the outer container has the effect of being coated by the inner container, so that the existing coating operation can be omitted. This shortens the process and does not require the use of chemicals required for coating, so it has the advantage of being able to produce cosmetic containers in an environmentally friendly manner.

On the outer circumferential surface of the portion 11, the inner container 10 is tightly closed to form a thread to prevent evaporation and deterioration of the contents, so that the lid can be opened and closed.

상기 내측용기(10)는 다양한 색상을 갖는 합성수지로 이루어지며, 상기 외측용기(20)는 투명 또는 반투명의 재질로 성형함으로써 내측용기(10)의 색상이 외측용기(20)를 통해 외부로 투영될 수 있도록 구성하는 것이 바람직하다.The inner container 10 is made of synthetic resin having various colors, and the outer container 20 is formed of a transparent or translucent material so that the color of the inner container 10 is projected to the outside through the outer container 20. It is desirable to configure it.

본 발명의 이중 화장품용기는 도 2에서 나타낸 바와 같이 내측프리폼 성형단계(S10), 외측프리폼 성형단계(S20), 프리폼 가열단계(S30), 블로우 몰딩단계(S40)를 순차적으로 거치며 제조된다.The double cosmetic container of the present invention is manufactured by sequentially passing through an inner preform molding step (S10), an outer preform molding step (S20), a preform heating step (S30), and a blow molding step (S40) as shown in FIG. 2.

상기 내측프리폼 성형단계(S10)에서는 블로우 몰딩에 의해 내측용기(10)를 이루는 프리폼(preform)을 성형하게 되는데, 도 3에서 나타낸 바와 같이 내측프리폼 성형금형(30)을 통해 성형한다.In the inner preform molding step (S10), a preform constituting the inner container 10 is formed by blow molding, and is molded through the inner preform molding mold 30 as shown in FIG. 3.

상기 내측프리폼 성형금형(30)은 상부금형(33)과 하부금형(31)으로 이루어져 있으며, 상기 하부금형(31)의 내측에는 프리폼의 형상을 이루는 성형공간이 형성되어 있고, 상부금형(33)의 내측에는 내측용기(10)의 토출부(11)를 이루는 공간과 용융된 액상의 합성수지 원료를 투입하는 원료투입구(34)가 형성되어 있다.The inner preform molding mold 30 is composed of an upper mold 33 and a lower mold 31, and a molding space forming a shape of a preform is formed inside the lower mold 31, and the upper mold 33 Inside, a space constituting the discharge portion 11 of the inner container 10 and a raw material inlet 34 through which molten synthetic resin raw materials are introduced are formed.

이러한 내측프리폼 성형금형(30)을 이용하여 도 4에서 나타낸 바와 같은 내측프리폼(10a)(Inner preform)을 성형하게 되는데, 상기 내측프리폼(10a)의 상측에는 내측용기(10)의 토출부(11)가 일체로 성형되며, 상기 토출부(11)의 하측은 추후 블로우 몰딩에 의해 내측용기(10)의 몸체를 이룰 수 있도록 소정의 두께로 성형되며, 내측에는 공간이 형성된다.The inner preform 10a (Inner preform) as shown in FIG. 4 is molded using the inner preform molding mold 30, and the discharge portion 11 of the inner container 10 is located above the inner preform 10a. ) Is integrally molded, and the lower side of the discharge part 11 is formed to a predetermined thickness so that the body of the inner container 10 can be formed by blow molding later, and a space is formed inside.

상기 내측프리폼(10a)의 내측에 형성되는 공간은 내측프리폼 성형금형(30)의 성형공간(32)에 삽입되는 핀(P)에 의해 형성된다.The space formed inside the inner preform 10a is formed by a pin P inserted into the forming space 32 of the inner preform molding mold 30.

이렇게 성형된 내측프리폼(10a)의 외측에는 도 5에서 나타낸 바와 같은 외측프리폼 성형단계(S20)에서 외측용기(20)를 이루는 프리폼을 성형하게 되며, 이때 외측프리폼 성형금형(40)을 이용하여 인서트 몰딩에 의해 성형한다.On the outside of the inner preform 10a thus formed, the preform forming the outer container 20 is formed in the outer preform molding step (S20) as shown in FIG. 5, wherein the insert is formed using the outer preform molding mold 40 It is molded by molding.

상기 외측프리폼 성형금형(40)은 하부금형(41)과 상부금형(43)으로 이루어지며, 상기 하부금형(41)의 내측에는 추후 외측용기(20)로 성형되는 프리폼의 형상을 이루는 성형공간(42)이 형성되어 있고, 상부금형(43)에는 프리폼을 이루는 합성수지 원료를 투입할 수 있도록 원료투입구(44)가 형성되어 있다.The outer preform molding mold 40 is composed of a lower mold 41 and an upper mold 43, and inside the lower mold 41, a molding space forming a shape of a preform that is later molded into an outer container 20 ( 42) is formed, and the upper mold 43 is formed with a raw material inlet 44 for inputting a synthetic resin raw material constituting a preform.

상기 외측프리폼 성형금형(40)에 의해 도 6에서 나타낸 바와 같이 내측프리폼(10a)의 외측에 소정의 두께를 이루는 외측프리폼(20a)(Outer preform)이 성형된다.The outer preform 20a (Outer preform) forming a predetermined thickness on the outer side of the inner preform 10a is molded by the outer preform molding mold 40.

상기 프리폼 가열단계(S30)에서는 성형된 내측프리폼(10a) 및 외측프리폼(20a)을 히팅장치를 이용하여 가열함으로써 내측프리폼(10a)과 외측프리폼(20a)을 일체로 결합시킨다.In the preform heating step (S30), the inner preform 10a and the outer preform 20a are integrally combined by heating the molded inner preform 10a and the outer preform 20a using a heating device.

상기 내측프리폼(10a)과 외측프리폼(20a)은 동일한 재질의 합성수지로 이루어져 있기 때문에 동일한 용융점을 갖게 되어 히팅장치의 가열에 의해 용융 결합됨으로써 일체로 결합된다.Since the inner preform 10a and the outer preform 20a are made of synthetic resin of the same material, they have the same melting point and are integrally joined by being melt-bonded by heating of the heating device.

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 simultaneously expanded 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.

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.A molding space 52 corresponding to the shape of the double cosmetic container to be molded is formed inside the blow molding mold 50, 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.Therefore, by injecting air at a suitable pressure through the blow hole 51, the heated preform expands at the same time, thereby forming an inner space filled with the contents of the cosmetic product, and having a shape having a shape corresponding to the forming 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 double cosmetic container of the present invention, which is molded through this manufacturing process sequentially, is formed by combining the inner container 10 and the outer container 20 integrally, thereby forming the inner container 10 on the inner surface of the outer container 20. It has the effect of coating.

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, thereby producing a cosmetic container in an environmentally friendly manner. There are advantages.

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, the inner container 10 made of raw materials in various colors is integrally coated by the transparent or translucent outer container 20, so that it is possible to pursue a higher quality of the product due to the directing of the image by 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 specific embodiments described above, and various modifications can be made to anyone having ordinary knowledge in the field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. will be.
