ABSTRACT:
A mouthpiece is designed to facilitate direct human consumption of liquid from a narrow-necked container, such as a bottle having a mouth defined by a peripheral rim that in use is enclosed by the lips of the consumer. The mouthpiece comprises a tubular body that engages the peripheral rim of the bottle mouth and forms an annular seal therewith and an adjoining extension that defines an annular wall projecting axially to surround the container adjacent its mouth. Vent passages in the mouthpiece communicate between an interior outlet receiving a tube for opening to the interior of the container, and an exterior inlet located on the surface of the mouthpiece at a position spaced from said free end by a distance sufficient to ensure that in use the inlet will not be blocked by the lips of the consumer and air can pass therethrough to the interior of the container to replace the liquid being consumed. The mouthpiece mounting section that engages around the outer surface of the peripheral rim of the bottle mouth is of compliant resilient material adapts readily to the form of the outer surface.
