Folding container

A foldable container, comprising:

• a bottom,
• side walls, which are hinged in a pivotally movable manner at an edge of the bottom in such a way that they can be folded in, respectively, from an erected position, in which the corresponding side wall extends upwards transversely to the bottom, into a folded-in position, in which the corresponding side wall extends at least substantially in parallel to the bottom,
• a lid which is configured to be placed on the side walls in their erected position in order to close the foldable container in a closed position, and to be placed on the side walls in their folded-in position so that it can be stored or stowed away in a space-saving manner in a storage position in case of an empty transport,
• a closure element that can be moved relative to the lid and which is provided at least partially in a portion of an edge of the lid in order to lock the lid in the closed position,
• at least one closure element mating piece which is provided at an edge of the side walls that faces away from the bottom in such a way at the side walls that, in the closed position of the lid, the at least one first closure element mating piece can interact in a form-fitting manner with the closure element, and
• at least one second closure element mating piece provided on a portion of the side walls that faces the bottom and/or on the bottom in such a way that, in the storage position of the lid, the at least one second closure element mating piece can interact in a form-fitting manner with the closure element in order to lock the lid in the storage position.
