Plastic container product

A plastic container product producible by a blow molding, filling and sealing method, the container product comprising:

• a container body containing contents;
• a head part adjoining the container body;
• an extraction area delimited by the head part;
• a head membrane closing the extraction area of the head part and having a free end face;
• a connecting seam on the head membrane extending through a surface spanning the head membrane, the connecting seam having a seam course at least partially deviating from a rectilinear course, extending on the head membrane, being longer than the rectilinear course and extending along an alternating course;
• and
• first and second penetrable areas being in the head membrane, being separated by the connecting seam and being at least partially encompassed by the connecting seam, the alternating curved course being a single sinusoidal wave having a wave trough and a wave peak each receiving one of the first and second penetrable areas therein.
