Apparatus for stacking containers of frustoconical shape comprises a pair of horizontal endless belts to support between them the containers in an upright position and advance them to fall from one end, means for tipping the containers as they fall so that their bottoms are foremost and a second pair of parallel horizontal belts located to catch and support the falling containers in an inclined position. These advance the containers towards means for braking them for adjusting the position of each before it is braked so that the bottom of the oriented container and the mouth of the braked container are telescoped. The containers, made of synthetic plastic and with an internal shoulder to prevent wedging when stacked are brought to a shoot 5 by a conveyer or guide channel from the manufacturing machine. Plates 13, Fig. 6 (not shown), suspended freely within the shoot, co-operate to tip the container on its side and allow it to fall and come to rest in an upright position between two endless belts 17. The containers are passed between vanes 26 which adjust their positioning and then past an air blast which rejects any which are still incorrectly positioned. At the end of belts 17 the containers fall past a baffle member 44, 45 which tilts them so that they are caught between the second pair of belts 39 in an inclined position, bottom foremost. They pass through a guide 47 which turns them on to their side and under a pair of rollers 48 which depresses their mouths, flipping their bottoms up so that they are m a position to enter the preceding container. They pass off the belts on to a track 63 on a sloping table 6 and under a brake 54 which contacts the rim of the leading container. The next container in line which is not yet braked telescopes into it and this is repeated to form a stack. An adjustable stop 65 is contacted by the leading container of the stack and operates a switch 67 to actuate an ejecting device 75 so that the stack is pushed off the track 63 on to the table 6. It rolls down the table guided by rails 81 until it meets a stop 77. A vane 78 acts to shape the stack temporarily into an arc 80, Fig. 3, to prevent it from rolling obliquely.
