Abstract
A moulded plastics drinking cup for use in beverage vending machines and intended to contain powdered solid water-soluble or dispersible ingredients has a bottom formed as an upwardly directed cuspidal cone extending from the central region of the cup bottom to the sidewall without discontinuity. This shaping confers a desirable flow pattern on hot liquid injected into the cup in the machine and avoids mixing problems incurred with prior art cup bottoms. The conical form need not be complete but may be truncated to give a relatively flat central region that may be planar or domed. The bottom and side wall are preferably interconnected by a bevelled shoulder.
