FIELD: packing industry.
SUBSTANCE: folding air insulation system comprises a cup and a folding air insulation hose with at least two longitudinal folds facilitating the hose folding. The hose is designed for the heat insulation of the cup by at least one air pocket. The folding hose comprises a tubular outer casing, a ferrule and an inner base or an outer base. The inner base and the said outer base are connected by a connecting base strip. The air pocket is situated between the tubular outer casing of the folding hose and the said cup. As the cup brims are wider than its base, there is a greater amount of air in the direction to the cup bottom, thus greater degree of heat insulation is achieved. The wider base makes the cups more stable as well.
EFFECT: improved temperature regulation and sufficient heat insulation, assistance for the user to grasp and hold the cup despite the excessive heat or condensation caused by the temperature of the cup content.
