  • a delivery point 13 at which a container closed by the device 1 with a container closure is delivered to a downstream device (not shown).
  • the first one A closure receiving area 44 extends upstream of the guide area 41, in which the closure unit 3 receives a container closure to be applied from a closure feed device (not shown).
  • the devices 1 of Figures 1 and 2 In the present case have the optional closure receiving area 44 and the optional return area 45.
  • FIGS 9 to 12 show side views of further preferred embodiments of the closing unit 3.
  • the closing unit 3 shown essentially corresponds to the closing unit 3 Figure 4 , whereby here the guide element-side support 34 comprises a recess 340 into which the upper part of the second guide element 32 extends. Accordingly, the upper end of the second guide element 32 and the upper end of the first guide element 31 are not arranged at the same height.
  • the closing unit 3 shown essentially corresponds to the closing unit 3 Figure 9 , whereby here the first spring element 31 and the second spring element 32 have the same spring length in the unloaded state and also have the same spring stiffness. Due to a recess 340 in the support 34 on the guide element side, when the closing units 3 are lowered, analogous to the previously described embodiments, the first spring element 31 only begins to deflect at a later point in time, which corresponds to the depth of the recess 340.
  • Closing unit 3 shown essentially corresponds to the closing unit Figure 4 , whereby here the first spring element 31 is arranged on the side of the closure receiving part 33.
  • Closing unit 3 shown essentially corresponds to that in Figure 10 shown, whereby here a plurality of first spring elements 31 are arranged regularly around the centrally arranged second spring element 32 in relation to a central longitudinal axis 38 of the closure unit 3 in the circumferential direction.
