Plastic tank and method of manufacturing a plastic tank

A method for producing a tank, the method comprising:

• placing at least one reinforcing profile member in a shell mould, the at least one reinforcing profile member having a retaining geometry region extending at least in a vicinity of an axial end of the at least one reinforcing profile member, the retaining geometry region having a plurality of openings;
• simultaneously forming a tank wall composed of a plastic material, maintaining a position of the at least one reinforcing profile member in the shell mould, and establishing a positive material bond connection between the tank wall and the at least one reinforcing profile member via application of a vacuum such that material of the tank wall flows against the walls of the shell mould and through and/or into the openings and onto a rear side of the reinforcing profile member facing away from the tank wall to thereby establish a positive material bond connection between the tank wall and the at least one reinforcing profile member at the retaining geometry region,
• wherein:
• the at least one reinforcing profile member is configured to minimize deformation of the tank,
• the at least one reinforcing profile member is configured for arrangement on an outer side of the tank wall to be engaged by the tank wall and establish the positive material bond connection therewith, and
• the at least one reinforcing profile member has a retaining geometry region extending at least in a vicinity of an axial end of the at least one reinforcing profile member, the retaining geometry region having a wider design than other axial portions of the at least one reinforcing profile member in a planar view of the tank wall.
