Abstract
A container with tear-opening device particularly suitable for single-dose containers, obtained by the injection of thermoplastic material in opposite molds, and consisting of a closure membrane having a particularly thin tear surface as to constitute a preferential rupture zone, having a section thermically calibrated by the shrinking (on cooling after injection). A process for obtaining said containers is also disclosed and claimed.
