• the mechanical advantages of the articulated quadrilateral are identical to those of the toggle joint of the first embodiment. This articulated quadrilateral also has greater resistance to fatigue due to a better distribution of forces.
• the substantially cylindrical sleeve 538 is arranged with its axis in a transverse direction substantially perpendicular to the direction of pushing of the button 508. It has a substantially elliptical section whose major axis coincides with the direction of movement of the pusher 508 and the minor axis with the longitudinal direction of sliding of the pump rod 504. During the pushing of the button 508 from its rest position to its active position, the parts of the sleeve 538 located at the ends 519 and 529 of said major axis are brought together transversely between the surface 508a and the rib 530.
• the sleeve 538 of substantially constant perimeter then deforms by spacing of the ends 518a and 520a of said minor axis, which causes the spacing of the washer 534 relative to the rib 532 and the sliding of the rod pump 504 in course 502.

• the bottle is replaced by a tank B with rigid wall 644 completely included in the housing R and movable longitudinally in the latter under the action of the toggle 618 to 620.
• the reservoir B has substantially a capital E shape with a base 650 from which extend two longitudinal wings 651 and a central neck 601 forming the neck longitudinally. of the reservoir in which the pump body 602 is fixedly mounted.
• the neck 601 is closed at its end by a transverse plate 643 traversed by the pump body 602 and having two end parts projecting transversely on each side of the neck 601 towards the lateral wings 651.
• the plate 643 fixed to the reservoir B serves bearing surface to each toggle arm 620 whose free end 620a is engaged in a notch 645 of the plate 643 to form a pivot connection with the latter.

• the toggle When the toggle is opened by a transverse thrust exerted on the membrane 607, it is the whole of the reservoir B and the pump body 602 which slides longitudinally towards the nozzle 610 around the pump rod 604, thus causing the expulsion of a dose of product.
