Description

종이 뚜껑{Paper lid for cups}
본 발명은 컵에 사용되는 뚜껑에 관한 것으로 특히 종이로 만든 뚜껑에 관한 것이다.
테이크 아웃(take out) 또는 인도어(indoor)용의 커피, 차, 아이스크림 등 모든 음료용 플라스틱 컵, 스티로폼 컵, 종이 컵의 뚜껑은 일반적으로 투명, 반투명의 플라스틱 뚜껑이 사용되고 있는 바, 이러한 플라스틱 뚜껑은 한 번 사용하고 나면 버려지는 것이어서 그에 따른 환경오염의 문제가 있을 뿐 아니라 유가 상승에 따른 제조 비용의 과다 소요의 문제가 있다.
그리하여 버려졌을 경우 용이하게 자연 분해되어 환경오염을 감소시키고 석유 제품을 사용치 아니하게 하여 유가 인상에 따른 부담을 감소시킬 수 이게 하기 위하여 종이제 뚜껑의 사용이 권장되고 있다.
그런데, 위와 같은 음료용 컵의 뚜껑은, 종래의 플라스틱제 뚜껑에 있어서와 같이, 위생적이고 방수처리 되어 있어야 하며, 여러 번 개폐 시 유연성을 갖고 찢 어지지 않고 복원성을 유지할 수 있어야 하며, 그리하여, 뚜껑을 닫았을 때 용기의 몸통과 밀착이 잘 되어 운반 중 흔들림에 의해 외부로 음료가 넘치는 일이 없어야 하며, 온도에 의한 신축 또한 없어야 한다는 조건을 충족시켜야 뚜껑으로서의 역할에 만족할 수 있는 것이다.
그런데, 종래의 종이제 뚜껑은 측벽의 강도가 지나치게 약하여 뚜껑이 컵에 완강하게 밀착되지 아니하여 컵으로부터 뚜껑이 쉽게 벗겨지는 결점이 있으며 작은 흔들림에도 음료가 외부로 일출되는 결점이 있어, 플라스틱제 뚜껑을 종이제 뚜껑으로 대체하는 일이 용이하지 아니하였다.
이에 본 발명은 측벽의 강도를 강화하여 뚜껑이 컵에 완강하게 밀착될 수 있게 하고, 그리하여 컵으로부터 뚜껑이 쉽게 벗겨지는 결점이 없는 종이 컵을 제공함으로써, 컵을 들고 이동하는 중에 컵이 흔들리더라도 음료가 외부로 일출되는 결점이 없게 하여, 플라스틱제 뚜껑을 대체할 수 있는 종이제 뚜껑을 제공하여야 한다는 과제를 해결하고자 한다.
위와 같은 과제를 해결하기 위하여, 본 발명은, 천판과 천판의 테두리에 하향으로 설치되는 측벽으로 구성되는 뚜껑에 있어서, 측벽이 보강재로 보강된 종이 뚜 껑을 제공한다. 본 발명은 이에서 나아가, 보강재를 종단면이 U자형인 테이프로 구성시켜 측벽이 U자형 테이프의 가운데 홈에 삽입 접합되어 구성되는 종이제 뚜껑을 제공한다. 또한, 본 발명은 U자형 테이프의 내 상단과 천판 사이에 수납부가 형성된 종이 컵을 제공한다. 본 발명은, 위에서 더욱 나아가, 천판에 절취선을 형성시켜 음료를 마실 때, 절취선을 따라 절취부를 뜯어 구멍을 내게 할 수 있는 종이 뚜껑을 제공한다. 이러한 절취선은 2단계로 형성되어 필요 음용량에 따라 구멍의 크기를 조절할 수 있게 하여서 되는 종이 컵을 제공한다.
위와 같은 본 발명은, 측벽이 보강재로 보강되어 있으므로 보강재가 너덜 너덜하지 아니하여 컵에 뚜껑을 긴밀하게 덮을 수 있어 뚜껑이 컵으로부터 용이하게 벗겨지지 아니하게 하는 효과가 있다. 특히, 본 발명은 보강재의 길이를 천판의 둘레보다 짧게 형성시킬 경우 뚜껑의 하단 둘레가 작아져 뚜껑의 이탈 방지 효과가 탁월한 종이제 뚜껑을 제공할 수 있다. 또한, 본 발명은 보강재의 내상단과 천판 사이에 수납부가 형성된 종이컵을 제공함으로서 수납부가 컵의 상단 둘레를 수납 파지하게 하여 뚜껑과 컵의 결합을 공고히 함으로써 뚜껑의 벗겨짐을 방지함은 물론 컵이 흔들리더라도 컵 속의 음료가 넘치는 일을 방지할 수 있게 하는 효과가 있다. 천판에 형성된 절취선은 필요 음용량에 따라 뜯어 내는 절취부의 큭로 구멍의 크기를 조절할 수 있는 효과가 있다.
천판(1)과 천판(1)의 테두리에 하향으로 설치되는 측벽(2)으로 구성되는 뚜껑에 있어서, 측벽(2)이 보강재로 보강된 종이 뚜껑을 제공한다. 이러한 종이 뚜껑은 일면 또는 양면을 합성수지로 코팅하여 형성시킬 수 있다.
측벽(2)은 천판(1)의 외측 주연부를 하향으로 절곡하여 형성시키되 측벽에 주름(10)을 형성시켜 구성되는 것이 바람직하나 천판(1)에 별도의 벽재를 접합하여 구성될 수 있다.
본 발명은 이에서 나아가, 보강재를 종단면이 U자형인 테이프(3)로 구성시켜 측벽(2)이 U자형 테이프(3)의 가운데 홈에 삽입 접합되어 구성되는 종이제 뚜껑을 제공한다.
또한, 본 발명은 U자형 테이프(3)의 내 상단(31)과 천판(1) 사이에 수납부(11)가 형성된 종이제 뚜껑을 제공한다. 이러한 수납부(11)는 컵의 상단 테두리를 수납하여 뚜껑이 제멋대로 열리지 아니하게 한다.
본 발명은, 위에서 더욱 나아가, 천판(1)에 절취선(12)을 형성시켜 음료를 마실 때, 절취선(12)을 따라 절취부(13)를 뜯어 제켜 구멍을 내게 할 수 있는 종이 뚜껑을 제공한다. 이러한 절취선은 2단계로 형성되어 필요 음용량에 따라 구멍의 크기를 조절할 수 있게 하는 것이 바람직하다.
본 발명은 또한, 첨부된 도면 도4에 도시된 바와 같이, 보강재의 외측 상단(32)을 천판(1)의 상위 까지 연장 형성시키고 연장된 보강재 상단에 두루말이부(4)를 형성시켜서 된 종이 뚜껑을 제공한다. 이러한 종이 뚜껑은 손으로 잡을 때의 감촉을 부드럽게하며 컵의 상품성을 고급스럽게 한다.
도1은 천판의 주연부를 절곡하여 측벽을 형성시키되 측벽에 주름을 형성시켜서 되는 뚜껑의 일 예시도
도2는 도1에 도시된 뚜껑에 보강재를 설치하여서 되는 본 발명의 일 실시예의 일부 절취 사시도
