Zusammenfassung:This disclosure provides new closure and finish structures suited for small and light-weight carbonated beverage packaging that provide surprisingly improved carbonation retention and greater shelf life, while still achieving light weight. This closure and finish presented herein are particularly suited to small PET containers for carbonated beverages, for example less than or about 400 mL and provide good carbonation retention and shelf life. La présente invention concerne de nouvelles structures de fermeture et de bague adaptées à des emballages de petite taille et légers pour boissons gazeuses, lesdites structures offrant, de manière surprenante, une rétention du gaz améliorée et une meilleure durée de vie, tout en restant légères. La fermeture et la bague selon l'invention sont particulièrement adaptées à des récipients de petite taille en PET pour boissons gazeuses, par exemple d'une contenance inférieure ou égale à environ 400 ml, et présentent de bonnes propriétés de durée de vie et de rétention de gaz.
