일반적으로 에센스, 아이크림, 노화방지제 및 주름방지제와 같은 기능성 화장품의 내용물은 액체, 겔 등 여러 형태로 이루어지는데, 이러한 화장품 내용물을 안전하고 효과적으로 저장하기 위해 다양한 화장품 용기에 수납되어 사용되고 있다.In general, the contents of functional cosmetics such as essence, eye cream, anti-aging agent and anti-wrinkle agent are formed into various forms such as liquid, gel and the like, and they are stored in various cosmetic containers for safe and effective storage.
상기 화장품 용기들 중 튜브 용기는 화장품의 내용물의 종류에 따라 신축성이 있고 연질(軟質)의 합성 수지, 알루미늄, 라미네이트 등의 다양한 재질로 형성되어 외부에서 표면을 인위적으로 압착하면 내용물이 가압력에 의해 토출구를 통해 토출되는 구조로 이루어져 있다.Among the above-mentioned cosmetic containers, the tube container is made of various materials such as synthetic resin, aluminum, laminate, etc. having elasticity according to the type of contents of the cosmetics, and when the surface is artificially compressed from the outside, And the like.
일 예로 라미네이트 튜브에 관한 종래 기술로는 대한민국 공개특허 제10-2004-0098885호가 개시되어 있는데, 이는 튜브의 내면을 이루는 튜브 내측 표면층과 외면을 이루는 튜브 외측 표면층으로 구성된 표면층과 가스투과를 방지하는 가스 차단층 및 상기 표면층과 가스 차단층을 접착시키는 접착제층으로 구성된 다층 라미네이트 튜브에 관한 것으로, 상기 가스 차단층은 알루미늄 박판과 플라스틱 필름과 알루미늄 박판을 순차적으로 적층하여 이루어져 있다. For example, Korean Patent Laid-Open Publication No. 10-2004-0098885 discloses a laminate tube, which comprises a surface layer composed of an inner surface layer constituting the inner surface of the tube and a surface layer constituting the outer surface of the tube, Barrier layer and an adhesive layer for bonding the surface layer and the gas barrier layer, wherein the gas barrier layer is formed by sequentially laminating an aluminum thin plate, a plastic film and an aluminum thin plate.
상기 종래 기술은 라미네이트 튜브에 차단층으로 알루미늄 박판을 사용하기 때문에 가스 차단성은 뛰어나지만 알루미늄 금속으로 인한 튜브의 복원력이 저하되고 튜브가 절곡될 경우 절곡된 부위가 절단되거나 파손되어 튜브 용기가 터지면서 내용물이 유출되는 문제점이 있다.In the prior art, since the aluminum thin plate is used as the barrier layer in the laminate tube, the gas barrier property is excellent, but the restoring force of the tube due to the aluminum metal is decreased. When the tube is bent, the bent portion is cut or broken, There is a problem of leakage.
이에 튜브 용기 사용 시 터짐 현상을 방지하는 종래 기술로는 대한민국 공개특허 제10-2006-0063596호가 개시되어 있는데, 이는 차단성 튜브 용기에 관한 것으로, 상세하게는 폴리올레핀 수지와 차단성 수지 나노복합체 및 상용화제가 건조혼합된 조성물을 성형하여 제조된 단겹 또는 3겹 차단성 튜브 용기에 관한 것이며, 또한, 종래에는 튜브의 내층은 저밀도 폴리에틸렌, 중간층은 admer, 외층은 저밀도 에틸렌으로 이루어진 3층 튜브를 사용해왔다.
