Abstract
A cosmetic container is provided with at least two ribs along its inner walls that extend inwardly so that an applicator such as a mascara brush contacts the ribs. This divides the container into at least two chambers defined by the rib and brush. Unscrewing the container cap causes agitation, mixing and stirring of the cosmetic product in the chambers by the flexing snapping action of the applicator brush against the ribs stirring up the product contained in the chambers. This provides an improved cosmetic product that has a consistent viscosity and color so that it can be applied more uniformly.
Claims19
A cosmetic product self agitation container, comprising:
- a bottle having a mouth for receiving an applicator, and having a plurality of radially inwardly extending axial ribs located on an inner bottle wall of said bottle apart from said mouth, said applicator being affixed to a bottle cap and having a plurality of brush elements extending radially outwardly from an axis of said applicator, said ribs extending inwardly sufficiently whereby the ribs contact the brush elements and thereby define a plurality of separate mixing chambers in said bottle, said mouth of said bottle having means for engagement and disengagement of the bottle cap by rotation, whereby rotation of the bottle cap during disengagement of the bottle cap from the bottle causes said brush elements to bear against and resiliently snap free from said ribs and thereby agitate a material contained in said bottle, and wherein effective mixing of said material occurs generally within the confinement of said separate chambers.
A cosmetic product self agitation container, comprising:
- a bottle having a mouth, a base and bottle walls extending therebetween, and three equidistantly spaced inwardly directed rigid axial ribs integrally formed with said walls of said bottle, said bottle having indentations corresponding to said ribs in an outer wall of said bottle, said ribs having generally triangular cross-sections having peaks, and said peaks of said triangular cross-sections have an angle of between about 45 degrees to about 120 degrees, an applicator being affixed to a bottle cap and having a plurality of bristles and being fittable into said bottle, said bottle having means for engagement and disengagement of the bottle cap by rotation, said ribs extending radially inwardly and said bristles extending radially outwardly from said applicator sufficiently whereby the ribs contact the bristles to define three separate chambers in said bottle when said bottle cap is engaged with said bottle, whereby rotation of the bottle cap to disengage the bottle cap from the bottle causes said bristles to bear against and resiliently snap free from said ribs and thereby agitate a material contained in said bottle, and wherein effective mixing of said material occurs generally within the confinement of each said separate chamber.
