VORFORMLINGE ZUM ERHALT VON BEHÄLTERN UND ENTSPRECHENDER BEHÄLTER

摘要

A preform for obtaining a container comprises a hollow body having a side wall extending around a longitudinal axis and an end wall arranged transversely to the longitudinal axis, a point of the end wall having a value of specific residual melting enthalpy; there is at least one point of the side wall having a further value of specific residual melting enthalpy that is greater than the value. A container comprises a containing body having a first end zone closed by a base wall and a second end zone suitable for engaging a closing element; there is at least one point of the base wall having a value of specific residual melting enthalpy that is significantly less than the specific residual melting enthalpy of the points of the containing body distinct from the second end zone.
