Description:
RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Provisional Application No. 61/729,914, filed Nov. 26, 2012, titled “Cosmetic Applicator,” the content of which is hereby incorporated by reference in its entirety. 
     
    
     FIELD 
       [0002]    The present disclosure relates generally to a product dispensing apparatus and, more particularly, to a product dispensing apparatus comprising a container, a cap, an elongate stem, and a wiper element configured to prevent a rotational movement of the elongate stem when cap is screwed onto the container. 
       BACKGROUND 
       [0003]    It is important in the cosmetic industry to provide an applicator for products which not only applies the product easily, but also avoids excess product from being dispensed onto the applicator prior to application. 
         [0004]    Prior art applicators typically have a stem that has a cross-sectional shape that is round or circular, so that when the cap to which the applicator stem is attached is unthreaded or unscrewed from the vial or container containing the product, the stem will twist through a wiper in the vial, wiping excess product off from the stem. 
         [0005]    However, the rounded styles of the stems of such applicators are not desirable. There remains a need in the art for an applicator which has more flexibility in size and style. 
       SUMMARY 
       [0006]    The present disclosure is directed to an applicator having an elongate stem that does not does not twist or rotate when the applicator is unscrewed from its container. In certain embodiments the applicator stem of the present disclosure is orientated such that the wiper in the vial holds the stem in place, while the inner cap or handle can spin about the stem when the inner cap is being unscrewed from or screwed onto the container. The inner cap or handle enables the stem to be axially pushed or pulled through a wiper element.
