A container having a container body, an open end and an opposed bottom. Around the open end of the container is a substantially continuous outwardly extending flange. The container has a lid for closing the container. The container flange and lid include complementary recesses and protrusions which ensure alignment of the lid with the flange when the lid is in the closed position. The container may have a tubular structure formed by two opposed side walls and two opposed end walls between the side walls. Opposed walls may have gussets, so that the walls are inwardly foldable towards each other and the container is collapsible and/or self-supporting. The container may also be collapsible via folding of the tubular structure.
