Applicator distributor of a pasty product

Aspects of the invention disclose an applicator distributor of a pasty product that flows by gravity, the applicator distributor comprising a body comprising a main reservoir for said product, a distribution head comprising at least one orifice and a removable cap. The cap forms a means for vertically placing the applicator distributor, and wherein the applicator distributor is a downward-facing applicator distributor, so that the product can flow by gravity to the head, and wherein, the head comprises: a peripheral member forming a means of attachment to said reservoir, a central member comprising a central arch obstructing said main opening and comprising a portion forming an application surface of said product, and at least one flexible element that can be deformed under an axial strain, and can form a secondary reservoir that can house a dose of said product, and that can be filled when said applicator distributor is facing downwards.
