Abstract: A container divider for separating bottles in a box or the like, is provided. The divider has a number of panels, cross members, and extensions of some of the foregoing, so that the divider can be cut from a single unitary sheet of material and placed and retained in an erected position without the use of glue. In one embodiment of the divider, a tab is hingedly connected to the remainder of the divider so that the remainder of the divider can be positioned in an upper end of a box and later in a lower end of it, when the bottles in the box are in an inverted and upright position respectively.
