A system for creating a container having a bottom and four lateral walls, said system comprising • a first plate-like member, hereinafter bottom member, configured to form the bottom of the container, • four second plate-like members, hereinafter walls, configured to form lateral walls of the container, and • an arrangement for interlocking the walls with respect to the bottom member so as to create a container in an assembled state, wherein said arrangement being configured to enable interconnecting and disconnecting of the walls with respect to the bottom member for assembly and disassembly of the container by moving the walls with respect to the bottom member, and said arrangement comprising • for each said wall a first elongated plate-material section secured to that wall while extending along an edge thereof to form a lower edge of a lateral wall in said assembled state, and • for each outer border of the bottom member a second elongated plate-material section secured to this bottom member while extending along the respective said outer border, each said second section having a first part extending substantially perpendicularly to a large surface of the bottom member designed to form the bottom of the container for extending substantially vertically upwards from said surface when placing the bottom member substantially horizontally, each said second section having a second part configured to allow introduction of said first section into the second section from above, assuming the bottom being placed substantially horizontally, with the corresponding wall tilted outwards from a centre of the container to be created by at least 20° from a vertical extension, to form a stop to said first section preventing lifting of the wall with respect to the bottom member in a vertical position of the former to be obtained upon said introduction by tilting the wall with respect to the bottom member, said first part of the second section being designed to provide support for the first section so as to prevent further tilting of the wall than to said vertical position and define said assembled state, and said sections (4, 10) being designed to enable disassembling of the container by tilting the walls outwards with respect to the bottom member to a position in which said second part of said second section allows lifting of said first section out of said second section, wherein said second part of each second section comprises a mid portion connecting to said first part while extending substantially perpendicularly thereto in a direction outwards from a said centre of the container to be created while resting on the bottom member and an end portion connecting to said mid portion opposite to said first part, pointing upwards when placing the bottom member substantially horizontally, making an angle with respect to the bottom member of less than 80° and configured to define said stop for said first section, wherein each said first section has a first part extending along a wall surface of a said wall downwards to bear against said first part of a said second section in said assembled state as well as a second part connecting to said first part of the first section and configured to bear upon said mid portion of said second section and extend substantially horizontally in said assembled state, and said end portion of each second section is configured to keep said first section inside said second section in a vertical position of the wall by preventing said second part of the first section to be lifted with respect to the bottom member, characterized in that each said second section is secured from above to the bottom member by screws, and that the second part of the first section has a portion bent back while allowing the head of a screw to be received under single-layered portions of said second part. • a first plate-like member, hereinafter bottom member, configured to form the bottom of the container, • four second plate-like members, hereinafter walls, configured to form lateral walls of the container, and • an arrangement for interlocking the walls with respect to the bottom member so as to create a container in an assembled state, • for each said wall a first elongated plate-material section secured to that wall while extending along an edge thereof to form a lower edge of a lateral wall in said assembled state, and • for each outer border of the bottom member a second elongated plate-material section secured to this bottom member while extending along the respective said outer border, each said second section having a first part extending substantially perpendicularly to a large surface of the bottom member designed to form the bottom of the container for extending substantially vertically upwards from said surface when placing the bottom member substantially horizontally,
