A thermally insulated container comprising: a main body moulded from a single piece of expanded foam; a lid; and a plurality of rectangular cool packs (6, 7, 8, 9), wherein: the main body has a base and four walls which four walls define a mouth of the main body of the container which mouth is arranged to be closed by the lid of the container, wherein: the inner surfaces (10, 11, 12, 13) of the walls of the main body taper from the mouth of the main body to a base of main body, such that the internal dimensions of the main body are greater at the mouth of the main body than they are at the base of the main body; the lid comprises a roof and four walls protruding downwardly from the roof, which walls define a mouth of the lid which mouth is arranged to engage with the mouth of the main body so that the lid may close the main body of the container, wherein the walls of the lid are shorter than the walls of the main body; and when the container is closed the cool packs (6, 7, 8, 9) extend from towards the base inside the main body towards the roof of the lid; characterised in that the inner surfaces of the walls of the lid are tapered at an angle greater than the angle of taper of the inner surfaces (10, 11, 12, 13) of the walls of the main body, the taper of the inner surfaces of the walls of the lid being such that positioning the lid on the main body with the cool packs (6, 7, 8, 9) arranged around the inner surfaces (10, 11, 12, 13) of the walls causes the cool packs (6, 7, 8, 9) to be aligned so that they extend vertically, perpendicular to an inner surface of the base of the main body. a main body moulded from a single piece of expanded foam; a lid; and a plurality of rectangular cool packs (6, 7, 8, 9), wherein: the main body has a base and four walls which four walls define a mouth of the main body of the container which mouth is arranged to be closed by the lid of the container, wherein: the inner surfaces (10, 11, 12, 13) of the walls of the main body taper from the mouth of the main body to a base of main body, such that the internal dimensions of the main body are greater at the mouth of the main body than they are at the base of the main body; the lid comprises a roof and four walls protruding downwardly from the roof, which walls define a mouth of the lid which mouth is arranged to engage with the mouth of the main body so that the lid may close the main body of the container, wherein the walls of the lid are shorter than the walls of the main body; and when the container is closed the cool packs (6, 7, 8, 9) extend from towards the base inside the main body towards the roof of the lid; characterised in that the inner surfaces (10, 11, 12, 13) of the walls of the main body taper from the mouth of the main body to a base of main body, such that the internal dimensions of the main body are greater at the mouth of the main body than they are at the base of the main body; the lid comprises a roof and four walls protruding downwardly from the roof, which walls define a mouth of the lid which mouth is arranged to engage with the mouth of the main body so that the lid may close the main body of the container, wherein the walls of the lid are shorter than the walls of the main body; and when the container is closed the cool packs (6, 7, 8, 9) extend from towards the base inside the main body towards the roof of the lid; characterised in that the inner surfaces of the walls of the lid are tapered at an angle greater than the angle of taper of the inner surfaces (10, 11, 12, 13) of the walls of the main body, the taper of the inner surfaces of the walls of the lid being such that positioning the lid on the main body with the cool packs (6, 7, 8, 9) arranged around the inner surfaces (10, 11, 12, 13) of the walls causes the cool packs (6, 7, 8, 9) to be aligned so that they extend vertically, perpendicular to an inner surface of the base of the main body.
