Abstract: A collapsible container has a bottom formed of a plastic preform with grooves along the peripheral edge wall of the plastic preform. The side walls of the container are inserted into the grooves. A supporting base is fastened as a folding part or as folding parts to one or more side walls. The number of parts to be manipulated is reduced by the fact that the supporting base is no longer provided as a separate part. The labor associated with the supporting base is limited to folding the folding part or parts against the side wall or walls when collapsing the container, and is limited to folding out the folding part or parts when assembling the container. In addition, the container is stabilized when filled. The items placed therein press against the folding part or parts such that the side walls are pressed into the grooves.
