ABSTRACT:
The invention is directed to a carafe (10) for carrying a beverage, with a vessel (12) formed in particular from glass and having at its opening an upper rim (26) upon which a plastic ring structure (28) is seated. Because the thermal expansion of plastics is about 20 times greater than that of glass, the seat of the plastic ring (28) on the vessel (12) may work loose due to the effect of changing temperatures to which the carafe (10) is exposed as when hot or cold beverages are filled in. In order to ensure a consistently firm seat also at varying temperatures, it is proposed in the invention that the plastic ring structure (28) be provided with inner (30, 36) and outer (38) detent means rearwardly engaging inner (20) and outer (24) undercuts of the vessel (12).
