  • Parison whose neck is based on an aromatic polyester, and in particular on pet, the neck including a thread having a profile in longitudinal section that is asymmetrical
    Patent number: 6635325
    Abstract: The parison (1) is made from one or more thermoplastic resins, and includes a neck (2) based on an aromatic polyester and preferably based on PET, which neck is provided with a thread and is not thermally stabilized. The thread has a profile in longitudinal section that is asymmetrical, making it possible to obtain a thread whose profile in longitudinal section is of improved symmetry after the neck (2) has been thermally stabilized. A receptacle, and in particular a bottle, is obtained by stretching and blowing a parison, and in which at least the neck (2) has been thermally stabilized, and has preferably been completely crystallized.
