Abstract: A divider for insertion in a box or like container for dividing the container into sections. The divider is formed of a paper product and includes a double thickness primary portion formed of a pair of divider panels joined together along a longitudinal connection with there being an end panel connected to each divider panel at each end thereof and the end panels extending normal to the divider panels. The divider panels in turn have end portions defined by transverse fold lines and the longitudinal connection between the end portions of the divider panels is rupturable, whereby the extent of the divider panels may be reduced and the extent of the end panels may be increased. Thus, a single divider may extend either longitudinally or transversely of a rectangular container.
