Abstract: A packing container of substantially cylindrical form is made from a convoluted blank with the end portions thereof sealed together. One end of the upper edge of the blank has a tab member extending circumferentially of the cylindrical container and the other end of the upper edge of the blank has a corresponding cut-out portion. The ends are overlapped, with the tab portion on the outside, to such an extent that the width of the seal is greater than the circumferential length of the cut-out portion so that the seal includes a finger-like extension up to the top of the container. A tear thread is attached around the inside of the container and extends along the outer tab portion so that when pulled it will tear through the finger-like seal thus facilitating opening of the container.
