FIELD: transport container production.
SUBSTANCE: present invention concerns a container (10) made by blow molding of a thermoplastic polymer, preferably a tongue-and-groove barrel having welded, pre-made by injection molding, tongue-and-groove fittings that have internal threads for storing and transporting liquid or liquid-flowing bottled products. In order to eliminate undesirable warping of the material in the containers obtained by blow molding due to long periods of cooling thickenings, for example, on threaded dowels and compressed seams, in accordance with the invention, a shortened welded tongue-and-groove fitting (32) is made in the upper bottom (30) of the container, on which a massive threaded welded head (12), previously made by injection molding, having an internal thread (20) is welded.
EFFECT: extension of the range of storing and transporting solutions.
