Thermal bag (1) comprising: - an internal wall (B) and an external wall (A) defining between them at least one hollow space (I), the external wall (A) is at least partly thermally insulating; - a cooling unit comprising a first containing mean (2a) defining an internal volume and containing a first substance (3 a), and a second containing mean (2b) defining an internal volume and containing a second substance (3b); the substances (3a, 3b) are selected so that the chemical reaction between the substances (3a, 3b) is endothermic so as to determine a lowering of temperature in an internal space (1e) of said bag (1); the internal volumes are separated from each other; wherein: - the containing means (2a, 2b) are disposed in the at least one hollow space (I); - between the first containing mean (2a) and the second containing mean (2b) there is at least one separator mean (4) configured to assume a non-operating configuration in which it maintains the substances (3a, 3b) separate from each other and an operating configuration in which it puts the substances (3 a, 3b) in communication with each other; the passage between the non-operating configuration and the operating configuration is able to be controlled manually by an operator; the first containing mean (2a) is a sac or a tube in a deformable material and the second containing mean (2b) is a coil shaped, or spiral or branched or finger or similar shaped, positioned below the first containing mean (2a). |
