The invention relates to a machine destined for the manufacture of containers having the shape of a truncated cone with square-like base. The machine in question is composed of the body 1, the piston 3 moving with the assistance of oil under pressure and having four bearings with adequately configurated recesses, four longitudinal guides 5 with recesses, the plate 9 supporting and guiding the foregoing guides as well as four pressure springs 10 and two traction springs respectively on the ends of the longitudinal guides 5. Said machine is characterised in that it is able to manufacture containers having sides of different length (surface) and in that the lateral sides of the thus-manufactured containers are not (by two) in parallel relationship but in oblique position as to the vertical. The advantage of the invention is that the containers in question can be safely superimposed since the base of the upper container is smaller than the lid of the lower one. |
