More precisely, the bores are formed in an upper, upwardly and outwardly conically widened wall section KWA, which merges downward into a substantially cylindrical wall section ZWA.
  • the holes ASB are in a manner to be described in more detail below about the interior of the hollow body with a pipe connection, namely a pipe socket in connection ROS in the operating state of the device via a suction line, not shown, such as hose, is connected to a suction device. Thanks to the obliquely upward bores ASB ambient air is sucked in and formed a kind of vacuum cone over the pouring spout.
  • the suction holes ASB have a rounding ARU at least at their outer end pointing toward the pouring opening SOE, in the present case, however, at both end regions, by means of which a local vortex formation and thus the noise development are reduced.
  • the suction device can be easily cleaned. Therefore, it can be provided that it consists of two or more parts and can be dismantled, which will be described in more detail below.
  • the suction device AER consists of at least one upper part OTE and a lower part UTE, wherein upper part and lower part are held together in use by a clamping device SSM and after opening of the clamping means to expose the annular body interior are separable.
