A device for changing the jet shape of free-flowing products, in particular of foodstuffs, including: an inflow area for the free-flowing products to enter, an outflow area for the free-flowing products to exit, and several channels through which to pass the free-flowing products. Each channel has an inlet allocated to the inflow area and an outlet allocated to the outflow area. Each inlet of a channel has a first cross sectional area. Each outlet of a channel has a second cross sectional area. In order to make it easy to adjust the shape and velocity profile of the filling jet, it is proposed that the second cross sectional area of at least one channel be larger than the first cross sectional area of this channel.
