Abstract
A careless roll of absorbent paper product such as toilet tissue is configured to be easier to mount to a rotary dispenser than careless rolls heretofore known. The careless roll includes a rolled web of absorbent paper product that is rolled about a winding axis into a cylinder having first and second flat ends, and a pair of depressions defined in the careless roll. A first of the depressions is defined on one side of the roll and is substantially centered with respect to a winding axis of the roll, and the second depression is on a second, opposite side of the roll and is also substantially centered with respect to the winding axis of the roll. Methods of making and using the coreless web are also described.
