An apparatus for holding cartons in a fully erected position while they are filled and sealed, has carriers 20 with two adjacent walls and a gate 26 that pivots between a horizontal open position and an upright position to clamp the carton, the carriers being mounted on a conveyer 22. The cartons are introduced two at a time into two adjacent carriers by transfer mechanisms 28, 30 (no details given). Attached to a stationary post 25a are cam means, (92), Fig. 2 (not shown) to move arms 80 by rods 81, 82 away from a stop 89 into the path of a trip lever 64. Contact with the lever closes the gates 26 to hold the cartons erect. Two cam means, arranged at different heights to operate the rods 81, 82 which are of different lengths, allow two gates to be closed simultaneously. The trip lever 64 is connected to an overcentre device Fig. 9 (not shown). When a carton is not present in the carrier, the gate 26 rests on the edge of the wall 50. A device, Fig. 12, for ejecting a filled, sealed carton C from a carrier 20 comprises a triangular shaped cam 120 (shown in plan) that opens the gates in succession, and deflecting fingers 122 each having a roller 124 that pushes a carton C clear of a projection 52 enabling stationary guides 114, 116 to urge it on to the discharge conveyer 34.
