A container for a thixotropic product includes a cap and a rod connected to the cap at one end thereof and having a brush at the opposite end which when the cap is attached to the container extends into the container through an orifice, the edge of which forms a wiping zone; an insertion channel is disposed at the entrance to the container and a helical spring is fixed on the interior of the insertion channel with the axis of the spring to substantially coinciding with the axis of the wiping zone with the spring being situated at least in the vicinity of a wiper with the inner diameter of the wiper being less than the largest diameter of the brush; when the brush passes into the interior of the spring while filled with the product, it is unloaded and reloaded as it passes over the turns of the spring which results in strirring of the product thereby breaking the thixotropy of the product.
Device for the application of a thixotropic product with the aid of a brush, especially a mascara for the eyelashes, comprising a container (2, 102) for the said thixotropic product, a movable cap (3, 103) joined to the container (2, 02), a rod (27, 127) integral with the cap (3, 103), disposed substantially along the axis thereof and projecting with respect to the said cap (3, 103), and a brush (28, 128) comprising bristles carried by the end of the rod (27, 127) opposite the cap (3, 103) as an extension of the said rod (27, 127), the brush (28, 128) penetrating into the interior of the container (2, 102) via a wiping zone, characterised in that a winding (18, 118) is disposed in the interior of the said container (2, 102), at least a main part (P) of which comprises a plurality of non-contiguous turns, the axis of the said part (P) of the winding substantially coinciding with the axis of the wiping zone, the non-contiguous turns of the said part (P) of the winding internally defining a cylindrical space, the section of which is homothetic with respect to the largest section of the brush (28, 128) in a homothetic ratio of less than 1, but sufficient to allow for the passage of the said brush through the part (P) of the winding (18, 118).
