Abstract: 본 발명은 내용품들의 뒤섞임과 변성을 막기 위한 개선된 휴대용 화장품 주머니에 관한 것이다.  
     휴대용 화장품 주머니를 사용함에 있어 내용품(휴대용 화장품 및 도구)들이 이동시 흔들림을 통해 뒤섞이게 되는데 이 경우 기존의 휴대용 화장품 주머니의 사용자들은 필요한 제품을 찾는데 상당한 수고와 시간을 들이게 된다.  
     또한 기존의 화장품 주머니들은 보온성이 부족한 저렴한 일반 합성소재의 소재를 사용하여 15도 내외를 유지해줘야 하는 화장품 내용물이 휴대상황에서 야외 온도에 따라 저온 혹은 고온에 노출이 되어 쉽게 변성이 올 수 있는 상황에 놓이게 된다. 
     따라서 본 발명은 형상기억소재의 부속재를 이용하여 내용물들이 뒤섞이는 것을 방지하고 적외선 및 자외선 차단소재와 상변이 물질을 이용하여 내용물의 상태를 보존하는 제품을 만들고자 하는 것이다.  
     상기 과제들을 해결하기 위해 주머니의 소재는 자외선과 적외선 및 가시광선을 차단하는 폴리에스터 패브릭과 상변이물질을 보유한 패브릭을 접착하는 방식으로 구성된 2-레이어 소재를 사용한다. 
     적외선 차단 패브릭은 그 소재 자체로 위 광선들로 인한 화장품의 온도 변화 등을 방지하고 이로 인한 변질을 막는데 의의를 가진다. 
     상변이물질 패브릭은 엠보싱형태로 패브릭 안에 상변이물질을 집어넣어 유연성을 가미한 소재를 사용하는데, 이 물질의 상변화과정에서 일어나는 흡열발열 반응을 이용해 주머니 안의 온도를 적절히 유지하는데 의의를 가진다. 
     부속재는 상온에서 폼 형태의 형상기억 소재를 선택하여 주머니 안에 내용품들을 배치하고 나서 부속재를 작게 압축하여 넣으면 소재의 형상 회복을 통해 주머니의 빈 공간이 다 채워져서 움직임에도 내용품들이 섞이지 않도록 한다.
