The present invention relates to the field of the transportation and storage of goods and, in particular, to a box or box-like transport container that can provide a high degree of thermal insulation. More particularly, the present invention relates to storage containers that comprise a box or box-like container that can be hand-held. In the field of logistics, there is a widespread requirement to protect a thermally sensitive load to ensure that certain types of produce and materials do not to pass through certain temperature thresholds. It is well known that, for example, vegetables when subject to extremes of temperature that they become flaccid, as the cell structure is broken down through the formation of icicles or through dehydration. In essence, in any transport container with a thermally sensitive load, the rate at which heat passes through the packaging material of the transport container - the amount of heat that flows per unit time through a unit area with a temperature gradient per unit distance must not extend beyond a permitted temperature range for the product. The present invention provides an improved corrugated sheet container.
