Abstract
There is provided an improved paperboard-load supporting pallet which includes a deck formed of a plurality of layers of paperboard material and also includes a plurality of runners attached to the bottom surface of the deck. Each of the runners includes spaced, parallel corrugations and is also formed of a plurality of layers of paperboard material. A novel method is also provided for forming the pallet of the present invention.
Claims28
A paperboard load-supporting pallet, comprising:
- a flat deck formed of a plurality of layers of paperboard;
- a plurality of runners extending in a longitudinal direction and attached to the bottom surface of said deck;
- each of said runners being formed of a plurality of layers of paperboard and each of said runners including a plurality of spaced, parallel corrugation sections;
- each of said corrugation sections including a flat section A attached to said deck, two leg sections B each connected to opposite ends of said flat section, and radius of curvature sections C each having a transverse axis;
- and
- said paperboard runners having a main grain direction in which a majority of the paperboard fibers extend in said longitudinal direction and perpendicular to said transverse axes to provide substantially improved structural rigidity to said runners.
A runner for a paperboard load-supporting pallet, wherein said pallet includes a deck formed of a plurality of paperboard layers, and wherein one or more of said runners are to be attached to spaced-apart locations on the bottom surface of said deck, comprising:
- said runner being formed of a plurality of layers of paperboard and including a plurality of spaced, parallel corrugation sections;
- each of said corrugation sections including a flat section A for attachment to the bottom surface of said deck, two leg sections B each connected to opposite ends of said flat section, and radius of curvature sections C each having a transverse axis;
- and
- said paperboard runner having a main grain direction in which a majority of the paperboard fibers extend perpendicular to said transverse axes to provide substantially improved structural rigidity to said runner.
A method of making a paperboard load-supporting pallet, comprising the steps of:
- forming a deck from a plurality of layers of paperboard;
- forming runners from a plurality of layers of paperboard wherein each of said runners have a plurality of spaced, parallel corrugation sections;
- said corrugation sections having a flat section A for attachment to said deck, two leg sections B each connected to opposite ends of said flat section, and radius of curvature sections C each having a transverse axis;
- forming said paperboard runners such that their main grain direction includes a majority of paperboard fibers which extends perpendicular to said transverse axes to provide substantially improved structural rigidity to said runners;
- and
- attaching a plurality of said runners to the bottom surface of said deck to form said pallet.
