Abstract: A transfer device (26) intended to move an object (8) between a support zone (28) and a cap (12), includes: a frame (30); at least one holding arm (32) which is able to carry the object (8) to be moved; and drive elements (36) which are carried by the frame (30), and able to move the holding arm (32). The drive elements (36) are able to move the holding arm (32) so that the opening (19) of the object is moved firstly along an initial trajectory portion which includes a component in accordance with a direction perpendicular to the support zone (28), then along a curve which extends through a point (119) of the trajectory (118) of the base (17) of the object, after the base (17) of the object has passed through that point.
