Method of manufacture of a passive temperature control carton for transport and storage

Abstract

A method of providing an insulating carton () for use in a cubic cold-chain container, the insulating carton () being formed of four lateral insulating panels () about an axis, together with a base () insulating panel arranged orthogonally to the axis, with each insulating panel having four edges, with respective adjacent panel edges mutually abutting, the carton () having side walls with mutually orthogonal first and second parallel edges of first and second lengths (LI & L) with the side panels extending a depth (D) to the base, the panels having a thickness (T); wherein the method comprises the VIP steps of: selecting a cubic former () for the insulating carton, having external dimensions in correspondence with the dimensions of an interior cavity of the insulating carton; placing the panels about the former (), whereby an inside face of each panel is directed towards a corresponding outside face of the former and an external face of each panel is directed away from the axis; applying adhesive tape () about the external faces of the panels, the tape having a width greater than the depth of the side panels; and, folding tape () extending from the sides of the towards the base, to secure the side panels to the base, and a system for providing an such a carton.
