A container having an internal space for thermally insulating one or more articles to be temporarily stored in the internal space. The container includes a number of space defining members, in the form of panels and flaps, that are held in a space defining relationship by releasable fastening means, such as hook and loop fabric material, whereby the container can be transformed from a closed configuration defining the internal space to an open configuration substantially exposing all of the space defining members providing access to cleaning of the members.
