Barrel (10) with a plug made of thermoplastic material that is provided in the vicinity of a bottom (12), to hold a driving means, with a handling ring (24), which is connected to the barrel wall by means of a rib (23) in annular form, in which the rib (23) in annular form, which with a conical barrel section (22) extending in the direction towards the bottom (12) limits a groove (30), is placed running inclined towards the outside in such a way that it forms an acute angle (a) with the longitudinal axis of the barrel, where the deepest part of the groove (30) is at a certain distance from the driving ring (24) below the same, characterized in that the annular rib (23) is connected to the barrel wall in the transition between an essentially cylindrical intermediate section (21) and the wall area (22) that extends conically in the direction of the bottom (12), because the angle (a) is 10 ° to 15 ° and because the angle (b) between the annul nerve ar (23) and the opposite conical wall section (22) of the barrel is approximately 40 ° to 45 °.
