Referring to
Generally, the first application zone 102 is formed on one side of the cylinder body 110, and the second application zone 104 is formed on the opposite side of the cylinder body 110. For purposes of description, a side of the cylinder is along the length of the cylinder.
According to
The ratio of the length of the first application zone 102 to the overall length, i.e., the ratio of dimension 122 to dimension 120 can range from 0.39 to 0.58.
The dimension 120 can be 16 mm, 16.5 mm, 17 mm, 17.5 mm, 18 mm, 18.5 mm, 19 mm, 19.5 mm, 20 mm, and 20.5 mm.
The dimension 122 can be 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm.

In one embodiment, in the lengthwise direction, the applicator 100 includes a section of constant diameter 130. According to
Material is removed from the cylindrical body 110 to form the first zone 102 and the second zone 104. The material of the applicator 100 is removed in locations to provide the applicator with a different durometer at the first zone 102 compared to the second zone 104. For example, applicator 100 has a higher durometer at the first zone 102 suitable to be used as a reservoir to carry lip gloss, lip stick, etc., and the second zone 104 has a lower durometer and includes a sculpted angled tip for upper lip precision application.
Referring to
The applicator 100 provides an angled surface at the tip 116 of applicator 100 for the primary application for precision areas, e.g. the upper lip, specific small areas on face. The area size, and angle are suited for maximum ease on application and delivery of formula dose. The front edge of on the side of the tip 116 is used as a further detailer, giving additional precision and outline capability.
On the side of the main body of the applicator 100, there is a large curved cavity shaped to receive a curved shape, e.g. a lower lip. The cavity volume is between X-y ml @ z viscosity, for optimized formula performance.
In
The applicator 100 for cosmetics comprises a generally cylindrical body 110 having a proximal end and a distal end, a first concave application zone 102 on a side of the cylindrical body 110 between the proximal end and the distal end, a second convex application zone 104 on an opposite side of the first application zone 102, wherein the second application zone 104 extends between the proximal end and the distal end, and the second application zone transitions into the tip at the distal end, and the tip 116 of the applicator 100 is formed between the first application zone 102 and the second application zone 104, wherein the tip 116 extends along the outer diameter of the cylindrical body 110 on the side of the first application zone 102, and the tip 116 extends along a length of the cylindrical body 110 distal from the first application zone 102.
In an embodiment, the first application zone 102 and the second application zone 104 do not have any straight edges or flat surfaces.
Above the first zone 102, material is not removed from the front side of the applicator 100, thereby forming the tip 116 at the front side at the distal end. The tip 116 extends fully to the maximum outer diameter of cylinder for a short distance at the front side as illustrated in
In an embodiment, the first zone 102 and the second zone 104 includes a layer of flocking 108 and 106, respectively. In an embodiment, the first zone 102 includes flocking 108 and the second zone 104 does not. In an embodiment, the first zone 102 does not include flocking and the second zone 104 includes flocking 106.
Optionally, at least one or both of the zones 102 and 104 may be covered with flocking. The flocking layers 108 and 106 may be comprised of fibers formed from nylon, cotton, acetate, viscose, polyester or a blend of such materials. Such flocking may alter the ability of the applicator 100 device to pick up product and transport it onto the fibers, and may also alter the way in which the product will be spread out along the fibers. The flocking 106, 108 may comprise a mixture of fibers of different kinds and/or different lengths and/or different diameters.
The flocked fibers may have a diameter ranging from 0.5 to 5 denier. The length of the segments of fibers used is from between 0.2 and 1 millimeter. To apply flocking, the fibers may be projected by a spray gun. The first zone 102 and/or the second zone may be covered with an adhesive, then a jet of air containing fibers of a synthetic textile fiber is then sprayed against the zones 102, 104 which have been rendered adhesive.
The flocking layers in one or both of the zones 102 and 104 may include a mixture of two types of, for example, polyamide fibers having a circular cross-section, which may have a substantially identical length, but a different diameter. The two types of fibers, for example, a length of about 0.5 millimeter. A first fiber type may have a diameter of about 0.1 millimeter, and a second fiber type may have a diameter of about 0.2 millimeter.
A mixture of fibers in one or both of the zones 102 and 104 may include from about 5% to about 95% of one type of fiber and the balance is a different type of fiber. For example, one or both of the zones 102 and 104 may include 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% of one type of fiber and the balance of a second type of fiber. For example, about 80% by weight of fibers of the first type of fibers and about 20% by weight of the second type of fibers. Such a mixture of fibers may render it possible to obtain a flocking layer that has a variable density of fibers per unit area along the surface. For example, regions that include a larger number of small diameter fibers are relatively more dense than regions in which fibers having a larger diameter are found. The presence of the smaller diameter fibers may render it possible to obtain a relatively soft application surface, whereas the larger-diameter fibers may render it possible to space the smaller diameter fibers apart, so as to create larger spaces between the fibers, which may render it possible to retain more product. Here again, an applicator may be obtained that has a relatively high take-up capacity while being relatively gentle during application.
Additionally or alternatively, the first zone 102 and the second zone 104 may include a hydrophobic coating or a hydrophilic coating.
The hydrophobic and hydrophilic coatings can be applied to the flocking if present.
In an embodiment, the first zone 102 and the second zone 104 include a hydrophobic coating.
In an embodiment, the first zone 102 and the second zone 104 include a hydrophilic coating.

In the alternative or in addition thereto, one or both of the first zone 102 and the second zone 104 may be treated to increase the surface energy, such as with a plasma treatment.
Hydrophobic or superhydrophobic coatings may include manganese oxide polystyrene (MnO2/PS) nano-composite, zinc oxide polystyrene (ZnO/PS) nano-composite, precipitated calcium carbonate, carbon nano-tube structures, and/or silica nano-coating.
Additional non-limiting examples of materials that affect wettability of a surface include, but are not limited to, amphoteric surfactants, anionic surfactants, cationic surfactants, non-ionic surfactants, and the like.
In the alternative or in addition thereto, one or both of the first zone 102 and the second zone 104 may comprise one or more nanostructures, microstructures, hierarchical structures, and the like that affect wettability of a surface. Non-limiting examples of nanostructures, microstructures, hierarchical structures, and the like include nanopatterned, micropatterned, and the like polymeric coatings. Specific examples include patterned silicon surface, perfluorodecyltriethyoxysilane (PFDTES) coatings, poly (methyl methacrylate) (PMMA) patterned structures, polystyrene (PS) (hydrophobic) patterned structures, and the like.
In an embodiment, the applicator 100, except for the coatings and flocking, is made of a monolithic material. Advantageously, the applicator is made of a relatively flexible elastomeric or thermoplastic material, for example polyethylene elastomer, polyester, block polyetheramide, polyurethane, nitrile or silicone, which makes it possible to have elastic deformation at the first zone 102 and the second zone 104.
