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

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 (L1 and L2) with the side panels extending a depth (D) to the base, the panels having a thickness (T);

• the method comprising:
• 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 a first adhesive tape about a first portion of the external faces of the panels;
• applying a second adhesive tape about a second portion of the external faces of the panels such that there is an overlap between said first and second adhesive tapes so that the first and second adhesive tapes collectively have a width greater that the depth of the side panels;
• and
• folding the first and second adhesive tapes extending from the sides towards the base, to secure the side panels to the base.

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 vacuum insulating panel having four edges, the carton having side walls with mutually orthogonal first and second parallel edges of first and second lengths (L1 and L2) with the side panels extending a depth (D) to the base, the method comprising:

• 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 vacuum insulation 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 vacuum insulation panels, the adhesive tape having a width greater than the depth of the side panels;
