Abstract:
1. A method of forming a disposable container from weldable plastic film comprising: cutting a first pattern from a weldable plastic film, 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 first 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; cutting a second pattern from a weldable plastic film, said second pattern comprising, folding each first quadrilateral about its folding line; folding each trapezoidal section about its first folding line; folding each second quadrilateral section about its second folding line; aligning the third side of each trapezoidal section with the fourth side of an adjacent trapezoidal section; aligning a 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 along with a corresponding trapezoidal section a side of said box extending between the first and second polygonal sections, wherein each side has a first edge opposite a second edge, wherein each first edge is defined by the third sides of each pair of aligned first and second quadrilateral sections and the third side of a corresponding trapezoidal section and wherein each second edge is defined by the fourth sides of each pair of aligned first and second quadrilateral sections and of each corresponding trapezoidal section; 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.
