Abstract: The invention relates to a plastic container product, in particular produced by the blow-molding, filling, and sealing method, having a container wall which can be pierced by means of a cannula in predefinable areas for the purpose of access to the container content. Said plastic container product is characterized in that, in order to avoid punched parts which arise when the container wall is pierced with a cannula, the mathematical product of the container wall thickness in the piercing area and the tensile modulus of the plastic material to ISO 527 is less than 400 MPa·mm, in particular preferably less than 300 MPa·mm.

Abstract: A storage or infusion bottle (1) has an integrally molded bottle neck (3) with a teat-shaped bottle feature (4, 5) projecting from its mouth end. The closed teat end wall (6, 7) of the bottle feature is puncturable by an infusion needle. A cap (8) is attachable to the bottle neck (3) and has a funnel-shaped cap feature (9, 10) with an interior space accommodating the free end region of the bottle feature (4, 5). The intermediate space between the end wall of the bottle feature (4, 5) and the opposing side of the cap feature (9, 10) is completely filled by a hat-shaped sealing element (11, 12) enclosing the bottle feature (4, 5) at least in its end region remote from the bottle (1).
