Lipstick case with means for push-back prevention

A cosmetic container comprising a first tubular sleeve;

• a helical channel extending along an inner periphery of said first tubular sleeve;
• a cosmetic carrier movable longitudinally upwardly or downwardly within said first tubular sleeve;
• at least one lug extending radially outwardly from said cosmetic carrier, said lug having a radially outwardly facing end received in said helical channel of said first tubular sleeve, said helical channel being defined by a bottom wall oriented substantially parallel to the longitudinal axis of said first tubular sleeve, an upper sidewall extending substantially perpendicular to said bottom wall, and a lower sidewall oriented at an acute angle to the longitudinal axis of said first tubular sleeve for wedging against said lug.

A cosmetic carrier for use in a cosmetic container, said cosmetic carrier comprising a base, a cylindrical sidewall extending upwardly from said base to define a cup for receiving and holding a cosmetic, and a pair of diametrically opposed lugs extending radially outwardly from opposite sides of said cylindrical sidewall, said lugs each being round in cross section and having a radially outwardly facing end defining a chamfered surface including a surface portion which is oriented generally parallel to a longitudinal axis of said cosmetic carrier and which includes a surface configuration which prevents downward movement of the cosmetic carrier within a cosmetic container under a downward axial force applied to said cosmetic carrier.

A cosmetic container comprising a first tubular sleeve;

• a helical channel extending along an inner periphery of said tubular sleeve;
• a cosmetic carrier movable longitudinally upwardly or downwardly within said first tubular sleeve;
• at least one lug extending radially outwardly from said cosmetic carrier, said lug having a radially outwardly facing end including first and second radially outwardly facing surface portions, said first radially outwardly facing surface portion being oriented generally parallel to the longitudinal axis of said first tubular sleeve and said second radially outwardly facing surface portion including a curved portion, at least said first and second radially outwardly facing surface portions being received in said helical channel of said first tubular sleeve, and said radially outwardly facing end has a configuration which prevents downward movement of said cosmetic carrier under a downward axial force applied to said cosmetic carrier.

• a cosmetic carrier movable longitudinally upwardly or downwardly within said first tubular sleeve;
• and at least one lug extending radially outwardly from said cosmetic carrier, said lug having a radially outwardly facing end which is substantially round in cross section and which is defined by a compound surface, and said helical channel includes a compound surface which is matingly configured as said radially outwardly facing end of said lug, said lug being received in said helical channel of said first tubular sleeve and said radially outwardly facing end having a configuration which wedges against said helical channel to prevent downward movement of said cosmetic carrier under a downward axial force applied to said cosmetic carrier.
