The present invention relates to a container of thermoplastic material. The container preferably has a bucket-form including a bottom-part with a lower and upper surface and a wall-part with an external and an inner surface wherein at least a part of the inner surface of the wall-part is coated. In a second aspect the invention relates to a lid of thermoplastic material. The lid is substantially disc-shaped with an upper and a lower side and optionally with a sealing device along the rim wherein at least a part of the lower side of the lid is coated. In a further aspect the invention relates to a method for treatment of thermoplastic material constituting a container or a lid. The invention also relates to the use of a container optionally in combination with a lid, for storing and transporting liquid paint and relates to the use of a method for manufacturing containers and/or lids for storage and transporting of liquid paint.
