Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of and priority to U.S. Provisional Patent App. Ser. No. 62/879,068, filed on Jul. 26, 2019, titled COSMETIC APPLICATOR, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the present disclosure generally relate to a cosmetic applicator for applying a flowable cosmetic or pharmaceutical product, in particular a liquid, viscous or semi-viscous liquid, an emulsion, a gel or a suspension, to a surface, in particular to a biological surface, for example skin of the human body. More particularly, the present disclosure generally relates to a cosmetic applicator with a roller.

BACKGROUND

Cosmetic applicators such as dip or wand applicators are known in the cosmetic industry. Cosmetic packages often include such applicators for dispensing a particular cosmetic contained in the package reservoir. The cosmetic applicator generally includes a stem with a cap at one end and an applicator head in the form of a brush, spatula or other applicator structure suitable for applying a cosmetic or a care product including viscous cosmetics, mascara, eye liner, lip gloss, hair color, wound care, skin care, under eye cosmetics, pharmaceutical and like products.

One such applicator is disclosed in U.S. Pat. No. 6,331,085 for applying and transporting a quantity of cosmetic product to a user's skin. The applicator comprises a generally cylindrical elastomeric tip with a long axis, the tip including a distal end portion having a distal extremity with at least one material-holding concavity formed therein, and said concavity having a rim. As another example, U.S. Pat. No. 7,481,591 discloses an applicator comprising a rod and an application surface formed of a plurality of cones. These cones have a certain elasticity and movability and can therefore massage the cosmetic product, which is stored between the plurality of cones, onto the user's skin.

While such applicators are generally satisfactory, there still exists a need for a cosmetic applicator for applying a satisfactory amount of a cosmetic product to a biological surface.

DETAILED DESCRIPTION

The following description should be read with reference to the drawings wherein the like reference numerals indicate like elements throughout the several views. The description and drawings show several embodiments which are meant to be illustrative in nature. For convenience, the present disclosure may be described using relative terms including, for example, left, right, top, bottom, front, back, upper, lower, up, and down, as well as others. It is to be understood that these terms are merely used for illustrative purposes and are not meant to be limiting in any manner.

FIG. 1 illustrates an example cosmetic package 10. The cosmetic package 10 comprises a container 20 for holding a cosmetic product and a cap 30. FIG. 2 illustrates the cap 30 and its attached applicator 15 removed from the container 20. The cosmetic package 10 according to one embodiment of the disclosure may be used to contain and apply the product (not shown) including a cosmetic or a care product. The cosmetic or care product may include viscous, semi-viscous or liquid cosmetics such as foundation, concealer, eye shadow, lip gloss, hair color, skin care, pharmaceuticals and like products. The container 20 may have an open top end 22 (shown in FIG. 4) with a collar 26 and wiper 28 disposed therein, and a closed bottom end 24. The container is configured for holding the cosmetic product. The applicator 15 is coupled to the cap 30 and may include a stem 40, roller 50, and holder 60.

As shown in FIG. 3, the top end 41 of the stem 40 is coupled to the cap 30 and the bottom end 42 of the stem 40 is coupled to the holder 60. The holder 60 holds the roller 50 while allowing the roller 50 rotate freely in either direction around a horizontal axis Y-Y that is transverse to a vertical axis X-X extending between the top end 41 and bottom end 42 of the stem 40. Rotation of the roller 50 is indicated by arrow 51 in FIG. 3. The holder 60 may be a swivel holder rotatably coupled to the bottom end 42 of the stem 40 such that the holder 60 pivots around the vertical axis X-X extending through the stem 40. Pivoting of the holder 60 is indicated by arrow 61 in FIG. 3. In the embodiment shown in FIG. 3, the stem 40 has a cross-section, taken transverse to the axis X-X, that is not round. The stem 40 may have a cross-section that is oval, elliptical, rectangular, square, or any other geometric shape. In other examples, the cross-section may be round.

In some examples, the holder 60 may rotate from a first position in which the outer surface of the holder 60 is flush with the outer surface of the stem 40, as shown in FIG. 2, to a second position in which the holder 60 is pivoted relative to the stem 40, shown in FIG. 3. Such pivoting may allow free rotation or may be limited in its extent. In some examples, the holder 60 may be pivoted up to 45 degrees relative to the stem 40. In other examples, the holder 60 may be pivoted up to 90 degrees relative to the stem 40. In further examples, the holder 60 may be pivoted up to 180 degrees relative to the stem 40. In still further examples, the holder 60 may be pivoted up to 360 degrees relative to the stem 40.

The exploded view in FIG. 4 and cross-sectional view in FIG. 5 show the elements of an example cosmetic package 10. The container 20 may include a collar 26 disposed at the open top end 22. The collar 26 may have a connection feature configured to engage a matching connection feature on an inner surface of the cap 30. As illustrated, the collar 26 has external threading.

In some embodiments, the container further includes a wiper 28 disposed within the container adjacent the open end. The wiper 28 is configured to remove excess product from the roller 50 while the stem 40 is removed from the container 20. In an example the wiper 28 may have an oval opening at the lower end thereof to generally match the outer profile of the stem 40, while having a circular upper end. For other stem shapes, such as rectangular or square, the wiper 28 may be differently shaped to match the stem. In other examples, a standard wiper shape, that is, circular on each end, may be used instead.

In other examples, the container 20 is devoid of any wiper structure. In such an example, any excess product may be drained as the applicator 15 is removed from the container 20. Alternatively, the roller 50 may be pressed or wiped against the inside surface of the collar 26 as the applicator 15 is removed from the container 20.

The roller 50 may be elongated along the horizontal axis, as shown in FIG. 4. In some examples, the roller 50 rotates around a pin 52 held at opposite ends by the holder 60. The holder 60 may have a post 62 that fits into a recess in the bottom end 42 of the stem 40 and allows the holder 60 to swivel relative to the stem 40. In other examples, the roller 50 may be spherical or elliptical, with or without a holding pin 52. In some examples, the outer surface of the roller 50 may be smooth, flocked, or covered with fabric. In other examples, the outer surface of the roller 50 may include projections, ribs, grooves, discs, slits, cuts, holes, dimples, or other surface features or surface treatments (e.g., abrading) that are suitable for loading, transporting and applying cosmetic product.

In some examples, the roller 50 may be constructed at least partially from a thermal storage material, such as ceramic, glass, stone, metal, metal alloy, or composites thereof, whether natural or synthetic, capable of retaining and transferring heat or cold for a period of time. Some example metals that may be used include, without limitation, stainless steel, aluminum, zinc, magnesium, tin, nickel, titanium, steel, tin, copper, brass, platinum, gold, and silver, and alloys, such as ZAMAK. Stone materials that may be used include, without limitation, any stone, rock, mineral, ore, gemstone, imitation gemstone, glass stone (including naturally occurring and man-made forms of glass), volcanic stone, coral stone, metallic stone or ore, magnetic stone, concrete, or composites thereof, whether synthetic or naturally occurring.

The cap 30 may include an inner cap 32 fixed within the cap 30 and configured to be coupled to the stem 40. The top end 41 of the stem 40 may be fixed to the inner cap 32 against rotation. In other examples, the stem 40 may be rotatably coupled to the cap 30, such as with a ring 44. The ring 44 may be disposed over the top end 41 of the stem 40 and may have a snap engagement with the inner cap 32, allowing the stem 40 to rotate relative to the cap 30. Rotation of the stem 40 relative to the cap 30 may be independent of rotation of the holder 60 relative to the stem 40, and rotation of the roller 50. The independent rotation of the stem 40, holder 60, and roller 50 provides improved control for application of the cosmetic product. For example, when the user holds the cap 30, the independent rotation of the stem 40, holder 60, and roller 50 allows the user to easily apply a cosmetic product to many angles and planes of the face or body.

The container 20 may be made of, for example, be polypropylene while the cap 30 and the stem 40, holder 60, and roller 50 may be formed of acrylonitrile butadiene styrene or any other suitable polymeric material. The stem 40, holder 60, and roller 50 may be formed of polyacetal or any other suitable polymeric material. The material for forming the wiper 28, if present, may be low-density polyethylene, foam, sponge, sintered block, aggregate of natural or synthetic fibers, woven or non-woven fibers, plastic, or a combination of such materials. The aforementioned materials for forming various parts of the cosmetic package 10 of the present disclosure are an example, however other suitable materials may also be used.

In some embodiments, the cosmetic package 10 including any of the container 20, cap 30, applicator 15 and their associated parts, may be made from any suitable clear or colored material such as, for example, thermoplastic elastomer (TPE), low density polyethylene (LDPE), synthetic polymer, partially of a resin such as, for example, acrylonitrile butadiene styrene (ABS), styrene acrylonitrile (SAN), pentachlorothioanisole (PCTA), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET, PETE, PETG), polyurethane, thermoplastics, thermosets, plastic, rubber, silicone, nylon, ceramic, glass, metal, alloys, or composite material, and/or combinations thereof. The term “plastic” may also or instead mean any synthetic resin suitable for the purpose such as polymethyl methacrylate (PMMA) or glass reinforced polypropylene (PPG) clear thick walled plastic. If glass, the glass jar may be double walled. Moreover, various elements may be made of any combination of substantially clear, substantially opaque, and/or translucent materials. Natural materials as wood, stone or leather may be used as well for decorative or other purposes. The materials may be rigid or semi-rigid. In some embodiments, the container 20 may comprise a transparent or translucent material so that the cosmetic product within may be externally viewed.
