Plastics connecting seam, plastics bottle with a connecting seam and method for the production thereof

A vessel device being formed as a plastics mold, which is at least partially blow molded;

• the plastics mold comprising at least two plastics workpiece areas which are formed in a flat manner in at least one area of each respective plastics workpiece;
• the plastics mold further comprising at least one plastics connecting seam for a fluid-tight connection of the at least two plastics workpiece areas,
• the plastics mold further comprising at least one aperture, wherein the at least two plastics workpiece areas are configured to define a periphery of the aperture so that the at least one plastics connecting seam extends along the periphery of the aperture, and wherein one of the at least two plastics workpiece areas includes a hook-like fold and the other one of the at least two plastics workpiece areas includes an end area having a rolled-up profile, the end area being rolled up so that the end area is configured to encompass and engage behind the hook-like fold, wherein the engaging behind occurs across an angle of more than 180°, thus enabling the hook-like fold and the end area to provide the at least one plastics connecting seam in such a manner that the hook-like fold and the end area are configured to support the connection strength of the connecting seam at least in response to a tensile load being configured to pull the at least two plastics workpiece areas apart.
