Zusammenfassung: | The present invention relates to a foam paper cup which efficiently blocks heat transfer from hot water or beverages. The foam paper cup includes a container body with a foam resin layer formed on a surface of base paper. An overlapping unit is formed from one end of one side of the container body to a virtual overlapping line (L1) separated inwards. A curling unit is formed from an end of an upper side of the container body to a virtual curling line (L2) separated downwards. An end of the other side of the container body is rolled in a round shape up to the overlapping line to be affixed to the end of the one side, and an upper end is curled outwards. A cutting unit is formed by cutting a portion of the body in a wedge shape in an inward direction from an overlapping area (A) where the overlapping unit and the curling unit are in common. A meshing part forming an end of the curling unit is arranged on an upper end of an inner side of the cutting unit of the overlapping area.
본 발명은 뜨거운 물이나 음료로부터 열전달을 효율적으로 차단하는 발포 종이용기에 관한 것으로, 원지 표면에 발포 수지층이 형성된 용기 본체로서, 일측 단부에서 내측으로 이격되는 가상의 중첩선(L1)까지 중첩부가 형성되고, 상측 단부에서 하측으로 이격되는 가상의 컬링선(L2)까지 컬링부가 형성되며, 타측 단부를 상기 중첩선까지 둥글게 말아 일측 단부에 접합하고 상단부를 외측으로 컬링하는 발포 종이컵에 있어서, 상기 중첩부와 상기 컬링부가 공통되는 중첩 영역(A)에서 상기 본체의 일부가 측부에서 내측 방향으로 쐐기 형상으로 잘려나간 커팅부가 형성되면서, 상기 중첩 영역의 커팅부 내측 상단에는 상기 컬링부의 끝단을 형성하는 물림편이 마련되는 것을 특징으로 한다. |
