Abstract
A packing body is formed from a sheet of foldable material by forming a first row of panels with first fold lines between adjacent panels, forming a second row of panels having a second fold line inducing a common fold line with an edge of at least one panel from the first row, the common fold line being substantially perpendicular to the first fold lines, and bending the panels in the first row along the first fold lines until the panels are positioned in a stack and bending the panels in the second row into a second stack and folding them along the common fold line above or below the first stack.
Claims14
A packing body for use in fluid contact comprising in combination:
- a sheet having a pattern of apertures, a first row divided into contiguous panels by at least one first fold line between the panels and a second row of panels containing at least one fold line normal to the first fold line;
- and
- said sheet being folded along said fold lines until said panels are substantially parallel to each other to form a stacked packing body.
A method of forming a packing body for use in fluid contact comprising the steps of:
- forming a sheet of flexible, foldable material having a pattern of apertures;
- providing parallel first fold lines in said sheet along a first axis of the sheet to form a first row of first panels;
- providing at least one second fold line perpendicular to the first fold lines to form a second row of second panels;
- folding the sheet along the first fold lines such that the first panels are stacked substantially parallel to each other;
- and
- folding the sheet along the second fold lines until the second panels are stacked over or under said first panels and are substantially parallel thereto.
