ABSTRACT:
Device for dispensing a fluid product, comprising a container (102) fitted with a dispensing member (103) comprising a dispensing head (104) which can be moved in translation and is fitted with a button (104a). A cap (106) covers the container (102) and the dispensing head (104), on which cap a lever (107) is articulated. The lever carries a bearing element (109) capable of bearing on the button (104a) of the dispensing head (104) in order to push in the dispensing head (104). The bearing element (109) has, in cross-section through a plane of rotation of the lever (107), a shape such that a force applied to the end of the lever (107) is transmitted to a constant point (P) of the button of the dispensing head (104) and in that while the head (104) is being pushed in, the point (P) of application of the force moves parallel to the axis of translation (X--X) of the head (104) of the dispensing member. The bearing element (109) more particularly has the shape of an involute of a circle (C).
