RELATED APPLICATION 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 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 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.
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.
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 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.

DETAILED DESCRIPTION Examples of the present disclosure are directed to an apparatus and method for an applicator. In the following description, numerous details are set forth. It will be apparent, however, to one skilled in the art, that the present disclosure may be practiced without some or all of these specific details.
FIG. 1 shows a front view of an example applicator 100. The cosmetic applicator 100 comprises an outer cap 102, an applicator arrangement comprising an applicator stem, also referred to herein as an elongate stem 110 and an applicator element 112, and a container 106 for containing a product 108. In an embodiment the elongate stem 110 comprises a metal, a plastic, a ceramic, a glass, or any combination thereof. The product 108 can be any type of a cosmetic, including but not limited to cosmetics to apply to the face, eye, and nail area such as, lip gloss, eye liner, mascara, a concealer, a blemish control material, a nail polish or nail hardener, and the like. The product 108 can be a liquid, a semi-solid material, a solution, a suspension, a powder, a cream, or an ointment. The product 108 can be a therapeutic product, a fragrance, or a consumer product such as paint.
FIG. 2 shows a cross-section view of the example applicator 100. The applicator 100 as shown in FIG. 2 illustrates the outer cap 102, the container 106, and the product 108. In an embodiment, the container 106 comprises a container threaded portion 116 which is externally threaded around a cylindrically shaped sidewall defining an opening of the container 106. In an embodiment, the container 106 comprises a metal, a plastic, a ceramic, a glass, or any combination thereof.
The applicator 100 of FIG. 2 also comprises an applicator arrangement comprising the elongate stem 110 coupled to the applicator element 112 at a distal end and coupled to the handle (inner cap) 104 at a proximal end. In an embodiment, the elongate stem 110 can be substantially flat. In an embodiment, the elongate stem 110 can be a non-circular stem such as an ovoid, oval, or a polygon. In an embodiment, the handle (inner cap) 104 comprises an inner cap threaded portion 114 which is internally threaded and dimensioned for cooperated threaded engagement with the container threaded portion 116. In an embodiment, the proximal end of the elongate stem 110 comprises a plurality of snap fasteners 122 configured to form a coupling of the proximal end of the elongate stem 110 to the handle (inner cap) 104. In an embodiment, the elongate stem 110 and the handle (inner cap) 104 are unitary. In an embodiment, the snap fasteners 122 enable the handle (inner cap) 104 to spin or rotate about the elongate stem 110 when the handle (inner cap) 104 is being unscrewed from or screwed onto the container 106. In an embodiment, the snap fasteners 122 enable the handle (inner cap) 104, coupled to the elongate stem 110, to be axially pushed or pulled through a wiper element 118. The wiper element 118 is configured to remove or wipe excess product 108 from the elongate stem 110 and applicator element 112 when the elongate stem 110 and applicator element 112 is dipped into the container 106 in order to pick up the product 108 and then withdrawn from the container 106 in order to apply the product 108 for its intended use. In an embodiment, the wiper element 118 and the container 106 are unitary.
In an embodiment, the wiper element 118 comprises a cup shaped body that can be inserted or mounted into the cylindrically shaped sidewall defining the opening of the container 106. In an embodiment, the wiper element 118 is constructed from a hard plastic, or from a flexible material such as rubber or synthetic rubber or the like. In an embodiment, the wiper element 118 comprises a metal, a plastic, a ceramic, a glass, or any combination thereof. In an embodiment, the wiper element 118 comprises a passage to permit or allow the elongate stem 110 and the applicator element 112 to slide through the passage.
In an embodiment, the outer cap 102 is a removable outer cap that engages the container 106 or the elongate stem 110.
