A support post for appliance packaging defined from a formed paperboard tube and including inner and outer walls with laterally directed stiffening beads formed from either wall and extending into free engagement with the opposite wall. The stiffening beads include opposed side panels with an integral apex portion therebetween. At least one side panel extends at an acute interior angle to the side from which the bead is formed for a generally lateral inclination of the bead to lie at least partially between planar portions of the inner and outer wall to form intermediate layers upon collapse of the inner and outer walls toward each other. |
