A pourer (101) for simultaneously pouring a liquid from a container and mixing air into the liquid. The pourer comprises an elongated annular body (102) which defines an outer surface having a part (103) which is adapted to be fitted into an opening of the container. The annular body defines a longitudinally extending through-going channel (104) and has an air intake opening (106) extending transversely to the channel and penetrating the body, so as to allow air to be sucked into the channel when liquid is flowing from the container through the channel. The channel defines a contraction (105) near the air intake opening, so as to generate a low pressure in the area of the contraction when liquid is flowing through the channel and thereby assist in sucking air into the channel through the air intake opening. A screen (107) with perforations (108) may be provided inside the channel (104).
A pourer for simultaneously pouring a liquid from a container and mixing air into the liquid, comprising an elongated annular body defining an outer surface, at least part of which is adapted to be fitted into an opening of the container, the annular body defining a longitudinally extending through-going channel and having an air intake opening extending transversely to the channel and penetrating the body, so as to allow air to be sucked into the channel when liquid is flowing from the container through the channel, the channel defining a contraction near the air intake opening, so as to generate a low pressure in the area of the contraction when liquid is flowing through the channel and thereby assist in sucking air into the channel through the air intake opening.
