  • Patent number: 5769354
    Abstract: A container arrangement constructed to enable a web of material (35) to be withdrawn from the outer surface of a generally cylindrical roll, preferably a roll of toilet paper or like material. The arrangement includes a roll container (1), which can be opened to enable depleted rolls to be replaced. The container (1) includes a web outfeed opening which is coaxial with the roll axis. Mounted at one end wall of the container (1) is a cylindrical guide member (4) whose circular peripheral edge is aligned coaxially with the axis (10) of the outfeed opening (63) and whose diameter exceeds the effective, initial diameter of an unused roll (3). The guide member (4) functions to deflect the web from the cylindrical surface of the roll as the web (35) is drawn through the opening (63). The guide member (4) is rotatably journalled (51) for rotation about an axis which extends generally coaxial with the roll axis.
