The invention relates to a plastic container () having a container wall () with an outside () and an inside. A surface () of the outside () has a structure at least in a first region (). Said structure is formed by elevations () and/or recesses (). Each elevation () or recess () has one or more boundary faces (). Each transition from a first boundary face () to a second boundary face () or to the surface () of the container wall () has a radius, which is less than or equal to 5 μm. The invention also relates to a method for determining a property of a plastic container and verifying the authenticity.

Plastic container and method for determining a property of a plastic container

A method for transferring a negative structure of a surface of an inner wall () of a blow molding tool () onto a surface of a plastic container. The method comprises the steps of heating at least one region () of a mold cavity () of a molding body () of the blow molding tool (), on which the negative structure is formed, inserting a preform into the mold cavity (), closing the blow molding tool (), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall () of the mold cavity (), cooling the region () by supplying a coolant through temperature control channels (), and removing the plastic container from the mold.

Method for transferring a negative structure of a surface of an inner wall of a blow molding tool, and plastic container

A blow molding tool () for a blow molding machine (). The blow molding tool () comprises at least one first blow mold half () and one second blow mold half (). The first blow mold half () has a baseplate () and a molding body (). At least one mold cavity () with an inner wall () is arranged in the molding body (). At least one region () of the inner wall () of the mold cavity () comprises, in the associated section of the molding body (), separate temperature control channels () for controlling the temperature of the region ().
