Abstract
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.
Claims18
A support post for a product packaging system, said post being elongate and including a first wall and a second wall substantially coextensive with said first wall, said first and second walls being laterally spaced from each other and defining a space therebetween, a bead integrally defined solely from said first wall along the length of said first wall, said bead including opposed sides, both of which extend from said first wall and toward said second wall, one of said sides extending at an acute included angle to said first wall, said walls including portions receiving said bead therebetween, said bead, under predetermined compressive loading, resisting collapse of said walls inwardly toward each other, said bead, upon compressive loading greater than said predetermined compressive loading, folding upon itself and defining multiple layers between and in addition to said walls.
A support post for a product packaging system, said post being elongate and including a first wall and a second wall substantially coextensive with said first wall, said walls being laterally spaced from each other and defining a space therebetween, said first and second walls having common longitudinal edges integrally joined by transverse end walls, a bead integrally defined from said first wall along and substantially coextensive with the length of said first wall, at least a portion of said bead extending at an acute included angle to said first wall between said first and second walls, said first and second walls including portions receiving therebetween said portion of said bead extending at an acute included angle, said bead projecting into free sliding engagement with said second wall and, under predetermined compressive loading, resisting collapse of said first and second walls inwardly toward each other, said bead, upon compressive loading greater than said predetermined compressive loading, folding upon itself and defining multiple layers between and in addition to said first and second walls.
A support post for a packaging system for products to be protected against vertical transverse compressive forces;
- said post being elongate and including a first wall and a second wall substantially coextensive with said first wall, said walls being laterally spaced from each other and defining a space therebetween, a bead substantially coextensive with the length of said first wall and extending transversely therefrom across said space toward said second wall, said bead including opposed sides extending from said first wall, at least one of said sides extending at an acute included angle to said first wall within said space, a second one of said sides of said bead extending at an obtuse included angle from said first wall, said bead being selectively collapsible between said walls to define multiple layers between and in addition to said walls.
A support post for a packaging system for products to be protected against vertical transverse compressive forces;
- said post being elongate and including a first wall and a second wall substantially coextensive with said first wall, said walls being laterally spaced from each other and defining a space therebetween, a bead substantially coextensive with the length of said first wall and extending transversely therefrom across said space toward said second wall, said bead including opposed sides extending from said first wall, at least one of said sides extending at an acute included angle to said first wall within said space, said bead being selectively collapsible between said walls to define multiple layers between and in addition to said walls, said post being formed with a generally right angular cross section defining a corner post with two angularly related post sections, said bead being within one of said post sections, a second bead in the second post section, said second bead including opposed sides extending from one of said walls, one of said opposed sides of said second bead extending at an acute included angle to said one of said walls in said space, said second bead being collapsible between said walls to define multiple layers between and in addition to said walls, said beads each include an apex portion between the sides thereof with said apex portion freely engaging the wall opposed from the wall from which the bead extends, and bulbous portions defined between said walls to each side of each bead.
