Collapsible container, preferably a collapsible bulk container, for the transport and storage of fluent and particle bulk goods. The bulk container includes a carrying base member which is provided with skids, collapsible side walls, preferably a so called liner in the form of a bag shaped inner layer and a lid. The side walls are moveably attached to the base member via hinges and that adjacent side walls are joinable. The lid is provided with one or more profiles, which profiles are intended to exert pressure on a part of the upper side of a filled liner, whereby the possibility for the liner to move in relation to the collapsible container during transport is reduced.
