Abstract: A method of disabling operation of a disposable print module that has an ink reservoir and a plurality of ink ejection nozzles including unused nozzles, and that serves to be mounted on a base of a postage meter, the method including the following steps: forming, in a prior step, a residual ink level counter using a determined first group of the unused nozzles; determining the volume of ink consumed; destroying one of the unused nozzles of the residual ink level counter every time the print module is mounted on a different postage meter base; destroying one of the unused nozzles of ink consumed exceeds a predetermined ink level; and disabling operation of the print module when all of the unused nozzles of the residual ink level counter have been destroyed.

Abstract: A fluid dispenser device designed to be mounted on the neck of a receptacle, said device comprising a dispensing member (1), such as a pump or a valve, and fixing means (2) for fixing the dispensing member to the neck of the receptacle, said dispensing member comprising a body (10) whose top end is provided with a collar (12) that projects outwards, said fluid dispenser device being characterized in that the fixing means comprise a substantially cylindrical ring (20) engaged on the body (10) under the collar, said ring (20) being in peripheral leaktight contact with the body by being radially clamped thereon.

Abstract: A fluid dispenser is provided with a dispenser member, a container (1) with a neck (10), and a fixing member (2) for fixing the fluid dispenser member to the neck of the container. The fixing member comprises a skirt (20) defining an inside wall. The fluid dispenser has an inside wall provided with at least two longitudinal ribs (23) extending over the height of the skirt. The ribs (23) cooperate by plastic deformation with an outside portion (11) of the neck (10).

Abstract: A dispenser for dispensing a fluid, the dispenser comprising a dispenser member, a container (1) with a neck (10), and a fixing member (2) for fixing the dispenser member to the neck, said fixing member forming a skirt (20) defining an inside wall (21) serving to cooperate with an outside peripheral surface (13) of the neck (10), said dispenser being characterized in that peripheral sealing means (15; 4; 5) are disposed between said inside wall (21) and said outside peripheral surface (13).

Abstract: A valve ball serving to come into leaktight contact against a valve seat so as to close off selectively a communication passageway for a fluid, said valve ball comprising a substantially spherical core and a covering surrounding said core, said covering defining a deformable surface suitable for adapting its shape to accommodate any surface imperfections of the valve seat.
