Method of making a container

A method of forming a disposable container from weldable plastic film comprising:

• taking a first weldable plastic film having a first pattern, said first pattern comprising a central first polygonal section comprising a plurality of sides and a first quadrilateral section extending from each side of the first polygonal section wherein each side of said first polygonal section is also a first side of one of said first quadrilateral sections and defines a folding line, wherein each first quadrilateral section has a second side opposite its first side and a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, wherein each first quadrilateral section has a width measured along its folding line and a height as measured transverse to its folding line between its first and second sides, wherein each first quadrilateral section has a height that is different than a height of an adjacent first quadrilateral section;
• taking a second weldable plastic film having a second pattern, said second pattern comprising a central second polygonal section comprising a plurality of sides and a second quadrilateral section extending from each side of the second polygonal section wherein each side of said second polygonal section is also a first side of one of said second quadrilateral sections and defines a folding line, wherein each second quadrilateral section has a second side opposite its first side and a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, wherein each second quadrilateral section has a width as measured along its folding line and a height as measured transverse to its folding line between its first and second sides, wherein each second quadrilateral section has a height that is different than a height of an adjacent second quadrilateral section, and wherein the second pattern has the same number of second quadrilateral sections as the first pattern has first quadrilateral sections;
• folding each first quadrilateral section about its folding line;
• folding each second quadrilateral section about its folding line;
• aligning the second side of each second quadrilateral section with a second side of each first quadrilateral section defining a polygonal box wherein the first and second polygonal sections define opposite ends of the box and each pair of aligned quadrilateral sections defines a side of said box extending between the first and second polygonal sections, wherein each side of the polygonal box has a first edge opposite a second edge, wherein each first edge is defined by the third sides of each pair of aligned quadrilateral sections and wherein each second edge is defined by the fourth sides of each pair of aligned quadrilateral sections;
• welding each second side of each second quadrilateral to its aligned second side of each first quadrilateral section;
• and
• welding the first edge of each polygonal box side to the second edge of an adjacent polygonal box side.
