Abstract:
1. A method of fabricating a device for ejecting a liquid or paste product, wherein the method comprises the following steps in order: aspiration of a product to be ejected into a volume of a container-holder of the ejection device using a puller member acting on a piston in the container-holder; demounting the puller member from the container-holder; removal of the puller member from the device for ejecting the liquid or paste product; assembling a lever onto a rear body, the rear body having a rear opening and a leaf spring, wherein the lever incorporates a forwardly extending horizontal upper part and a lower end in the form of an axle; inserting the axle into the rear body along an axis of the rear body, the leaf spring of the rear body deforming to receive the axle; assembling the rear body to the container-holder; and inserting a rack through the rear opening until the rack causes the leaf spring to lock the axle along the axis and reaches a position in which a front face of the rack acts on the piston enabling ejection of the product from the volume.
