FIELD: process engineering.
SUBSTANCE: set of inventions relates to method of producing plastic container and device to this end. Proposed method comprises attachment of flexible flat part edge on hollow body inner surface, said part having convex and concave surfaces. Edge of the part is brought in contact with hollow body inner surface. Pulling or pushing force is applied to part central section perpendicular to part surface. Aforesaid force creates radial forces that move part edge towards hollow body inner surface. Proposed device is intended for producing plastic container consisting of hollow body and, at least, one flat flexible part that forms curvilinear surface with its edge attached to hollow body inner surface. Mantioned device comprises gadgets to apply pulling or pushing forces to the part central section perpendicular to its surface to generate radial forces directed towards part edge.
EFFECT: method produce containers by welding.
