Abstract: A ventilation device for introduction into a bag wall of a bag and bag with a ventilation device including a dust protection layer and a fluid-tight outer layer, wherein a ventilation opening is introduced into the outer layer is disclosed. A fluid-tight spacer device is arranged between the dust protection layer and the outer layer, wherein a free cross section of flow is made available between the dust protection layer and the spacer device and a free cross section of flow is made available between the outer layer and the spacer device, and wherein the spacer device includes at least one through-opening. In the method of production, the individual layers are made available, and spacer elements are made available by impressions.

Abstract: The invention relates to a device (1) for filling open bags (2) with powdery food, comprising a support structure (3) and a filling spout (4) accommodated on the support structure (3), on which a bag (2) to be filling is suspended. The bag (2) is maintained on the filling spout (4) by means of a bag holder (5, 6). The support structure (3) comprises a hollow profile (10, 11) with a control component (20) accommodated therein in order to protect against soiling. The hollow profile (10) comprises an air outlet (8) for controlling, in the hollow profile (10) when in operation an air pressure higher than the environment.
