Dispenser (1, 1′) of a product (7), typically a cosmetic product, comprising a receptacle (2) that includes a bottom (20) and a lateral axial wall (21), forming a cavity (22) that is intended to contain said product (7), and a cover (3) that includes a head (30) and a skirt (31) and that is intended to work with said receptacle (2) for the purpose of closing it when said dispenser (1) is said to be closed, in which:

• a) said receptacle (2) includes a body (4) comprising an outside axial wall (40) and an inside axial wall (41), said outside axial walls (40) and inside axial walls (41), of height He and Hi respectively, being attached by their bottom ends (401, 411) forming an annular bottom (42), in such a way as to form between themselves an annular axial cavity (43), said cover (3) being able to be temporarily attached to said outside axial wall (40), typically on its upper end (400),
• b) said receptacle (2) comprises a horizontal wall (5) forming a support for said product or all or part of said bottom (20) of said cavity (22), said horizontal wall (5) being attached to said inside axial wall (41),
• c) said receptacle (2) comprises an axial annular skirt forming a collar (6) of height Hj that works with said body (4), said collar (6) being able to be moved axially in said axial annular cavity (43), typically by manual effort, so that said collar (6) forms all or part of said lateral axial wall (21) of said cavity (22), said cavity (22) having a variable volume due to the relative axial movement of said collar (6) with respect to said body (4), said cavity (22) having a cavity height Hc, said cavity having a maximum cavity height HcM when said collar (6) is in the so-called “up” position relative to said body (4), said receptacle (2) having a maximum height HM and said cavity (22) then being able to contain a maximum amount of said product (7), and said cavity (22) having a minimum cavity height Hcm when said collar (6) is in the so-called “down” position relative to said body (4), said receptacle (2) having a minimum height Hm and said cavity (22) being able to contain a minimum amount of said product (7).
