  • the invention is based on the finding that it is expedient to realize the ventilation function exclusively with a separate ventilation duct, without a handle being included in the ventilation concept. In this way, it is initially prevented that liquids can collect in the handle.
  • the invention has recognized that it is not necessary to draw such a separate ventilation duct into the rear end of the container, but that it is possible to work with a relatively short ventilation duct which also ends with its lower end in the front region of the container, if the ventilation channel has a "down" tapered cross-section.
  • the channel preferably has a larger cross section at its upper end than at its lower end. This prevents liquid from entering the ventilation duct. Because with the containers known from practice there is the problem that in the course of emptying the liquid penetrates where actually the air is to penetrate for venting, namely in the area of the ventilation duct. By dimensioning this invention is this

  • the container according to the invention is characterized by a simple structure, because the handle itself does not have to be included in the ventilation concept.

  • the cross section at the lower end of the channel is at least 20% lower than at the upper end of the channel, particularly preferably at least 40%. It is preferably provided that the ventilation duct tapers continuously and / or stepwise from the upper channel end in the direction of the lower channel end without widening.
  • the invention also includes embodiments in which, in spite of regionally tapering, widenings are also realized from the upper channel end in the direction of the lower channel end, in which case it must nevertheless be ensured that the cross section at the lower channel end is smaller than the cross section at the upper channel end.
  • the interior of the handle is closed at least partially. This succeeds, for example, in that the handle is squeezed. In any case, the handle is not integrated into the ventilation duct concept.
  • the tapered ventilation duct can extend into a region lying in a side view between the pouring spout and the rear grip end of the handle. It is therefore within the scope of the invention that the tapered ventilation duct is oriented at least partially obliquely to the vertical, based on a vertical orientation of the container. The lower end of the channel is therefore not arranged directly under the upper channel end in such an embodiment, but laterally or rearwardly, offset towards the center of the container. Alternatively, however, the invention also encompasses embodiments in which the tapering ventilation channel is oriented essentially perpendicular to the vertical, again with reference to a stationary orientation of the container.
  • the lower end of the channel is consequently not arranged laterally or rearwardly offset in the container interior, but directly below the upper channel end.

  • the ventilation duct extends with its lower end into an area below the pouring spout, without however being arranged offset to the pouring spout.
  • the invention has recognized that the advantages described can also be achieved with a relatively short, vertically oriented ventilation duct, which may possibly even be completely integrated into the pouring spout.
  • the described effects prevent liquid from penetrating into the ventilation channel, so that the ventilation channel can perfectly fulfill its ventilation function in which the air flows in. This succeeds even when the ventilation duct is as it were in the liquid.
