A thermally insulating container comprising:
- an outer closable carton,
- a first substantially rigid insulating housing removably disposed within said outer carton and formed of a first thermally insulating material different from the material of the outer carton,
- a second substantially rigid insulating housing removably disposed within said first housing and formed of a second thermally insulating material different from the first thermally insulating material and from the material of the outer carton, and
- an inner closable carton removably disposed within said second housing.
A thermally insulating container comprising:
- an outer closable carton,
- a first open-top insulating housing removably disposed within said carton and formed of a first thermally insulating material,
