Abstract: A flange for fastening a line to a pump casing, includes: a pump casing passage; and a plurality of stop members protruding in the passage and angularly distributed around the passage, the position of the flange being angularly adjustable by the stop members. A pump may include the fastening flange. A method for adjusting the position of the flange in relation to the pump is also disclosed. This method makes it possible to avoid the position of the pump casing being imposed by the orientation of the fastening flange of the pump casing.

Abstract: A fluid dispenser device comprising: a body (10); a reservoir (20); a dispenser member (30), such as a pump or a valve, that is mounted on the reservoir (20); and a lateral actuator system (40) that is secured to said body (10); the device further comprising a ring (50) that is mounted on or secured to the reservoir (20), said ring (50) including at least one radial projection (55) that is adapted to co-operate with a movable element (45) of said lateral actuator system (40), the device being characterized in that said at least one projection (55) is beveled with a sloping radial end surface (56).

Abstract: A protective cap for covering, in a closed position, a dispenser head (4) of a fluid dispenser, said head including an end wall (40) incorporating a dispenser orifice (401), and a lateral wall (42), said cap including, on its inside, at least one sealing profile (500, 520) that, in the closed position, co-operates in leaktight manner with the lateral wall (42) of the head (4), in the proximity of said dispenser orifice.
