Claim 11:
12. A kit for making a packaging for the cooled storage of at least one product, comprising
a first waterproof sheet formed to a first configuration, wherein the first configuration comprises a first arrangement of creases, cuts, and partial folds, that provides a physical ability to transform, via a sequence of folding actions, the first waterproof sheet from the first configuration to an outer casing that comprises
(i) a base,
(ii) a wall extending upward to a packaging height above the base;
(iii) a lid, flexibly connected with the wall at the wall's packaging height, and extending from the wall to a lid edge, in a configuration enabling manually actuated movement of the lid, moving the lid edge in an arcuate path about a rotation axis aligned with the flexible connection to the wall with extending along the flexible connection, to and from a closing position and an opening position,
(iv) at least two additional walls, each extending upward from the base to a respective upper edge at the packaging height above the base;

a second waterproof sheet formed to a second configuration, comprising a second arrangement of creases, cuts, and partial folds, enabling through another sequence of folding actions, a transforming of the second waterproof sheet from the second configuration to an inner compartment within the outer casing, the inner compartment having least three sides and enclosing an interior volume for accommodating the at least one product, and
at least a third sheet, formed to an at least third configuration, comprising a third arrangement of creases, cuts, and partial folds, enabling through still another sequence of folding actions, a transforming of the third sheet from the at least third configuration to a spacer made of laminated cellulose product and arranged between the outer casing and the inner compartment in a configuration maintaining the inner compartment at the distance from the base of the outer casing,
wherein the outer casing and the inner compartment form, in combination, a coolant compartment which
(i) is separated from an interior of the inner compartment and surrounds the inner compartment on the at least three sides,
(ii) is fillable with water and is water-tight, and
(iii) when filled with water permits freezing of the water within the coolant compartment,

wherein the first single sheet, or the second single sheet, or both, comprise a laminated cellulose product,
wherein the laminated cellulose product comprises waterproof lamination which faces the coolant compartment,
wherein the lid is further configured to perform, in the closing position, a confining of an upper portion of the coolant compartment, and in the open position, no confining of the upper portion of the coolant compartment.
