Patent Application
20250228350
The present disclosure generally relates to an adjustable roller applying member for applying a fluid product.
Conventional cosmetic applicators are designed with a gripping member, a stem, and an applicator element located at one end of the stem. Various patents, such as U.S. Pat. Nos. 6,026,823, 4,165,755, and 4,428,388, and U.S. Pat. Appli. No. 20120201593, describe applicators for cosmetic product application.
Certain cosmetic applicators for makeup or care products have applicator element that have the ability to move relating to the gripping means or the stem. For instance, U.S. Pat. No. 6,026,823, discloses an applicator with a product reservoir, removable cap, and wand, allowing angular movement up to 90°. U.S. Pat. No. 4,165,755 describe applicator with a gripping member, stem, and applicator element, articulated to provide movement.
However, these applicators have limitations in precision, flexibility, and freedom of movement. The disclosure aims to address these issues by providing an ergonomic and adjustable roller applying member that enhances makeup or care application and offers a smooth massage experience. The roller applying member is designed to be flexible, precise, and capable of reaching all parts of the face comfortably. The cosmetic applicator allows for different angles of application for various cosmetic needs, eliminating the inconvenience of carrying multiple implements during travel.
It is an object of the present disclosure to provide a cosmetic applicator that provide a more user-friendly tool for makeup application, ensuring easy access to all facial areas by allowing for different angles of application. The cosmetic applicator is intended for delicate or tired areas, enabling a light massage.
Accordingly, there is provided a cosmetic applicator equipped with a roller applying member that is rotatable around its own axis and can also be flexibly adjusted to various angles relative to a longitudinal axis of the cosmetic applicator.
According to an aspect of the present disclosure, there is provided a cosmetic package for storing and applying a cosmetic product, equipped with cosmetic applicator of the present disclosure. The cosmetic package comprises a container for holding the cosmetic product and the cosmetic applicator. The cosmetic product can be more viscous than water or, optionally, even pasty, gel, solid or even powder. The cosmetic applicator comprises a cap, a stem, a collar, a swivel connector, and the roller applying member.
According to an aspect of the present disclosure, the cap of the cosmetic applicator has internal threads that can be screwed onto outer threads, formed on a neck of the container. The roller applying member is connected at a distal end of the stem via the collar and the swivel connector. The cap is connected at a proximal end of the stem.
In general, the use of the terms “distal” and “proximal” herein is supposed to mean that the distal is the end facing towards the inside of the container, whereas the proximal is the end facing towards the removal opening of the container.
According to an aspect of the present disclosure, the distal portion of the stem is a stepped-in stem portion that has a diameter less than the rest of the diameter of the stem. A distal surface defined at the end of the stepped-in stem portion is a concave surface.
According to another aspect of the present disclosure, the cosmetic package includes a wiper for wiping off excess product from the cosmetic applicator, the wiper is inserted into the neck of the container.
Specifically, the roller applying member of cosmetic applicator is used to apply the product including a cosmetic or care product. The cosmetic or care product includes viscous cosmetics, mascara, eyebrow powder, lip gloss, hair color, skincare, under-eye cosmetics, pharmaceutical, and like products.
According to yet another aspect of the present disclosure, the roller applying member is connected to the stem through a swivel connector featuring a spherical ball and a shaft, enabling users to pivot the roller applying member to their preferred angle. Additionally, the collar is connected to a distal end of the applicator stem, and this collar serves to secure the swivel connector within a spherical housing created by the concave distal surface of the stem and an interior cavity of the collar. The swivel connector allows the roller applying member to move independently and relative to the stem.
Further, the collar is coupled to the distal end portion of the stem, more particularly to the stepped-in stem portion. The collar may be made of metal, plastic, or any other suitable material. The collar has a cylindrical sidewall, and a distal wall with a distal cutout. In a preferred embodiment, the cylindrical sidewall has an annular groove at inner surface thereof. This annular groove is design to receive an annular protrusion located on the outer surface of the stepped-in stem portion, facilitating coupling of the collar to the stem.
According to yet another aspect of the present disclosure, the distal cutout of the collar is substantially circular. However, in other implementations, the distal cutout may be substantially square-shaped, circular, triangular or of any other suitable shape. The collar secures the swivel connector in the housing of the collar such that the shaft of the swivel connector protrudes through the distal cutout. The swivel connector permits the roller applying member to rotate through a plane defined by the distal cutout in the collar. The cutout defines a range of movement of the swivel connector. Such a ball and socket connection allow rotation of the swivel connector, about a longitudinal axis of the stem, and the rotation may take place in the clockwise or counterclockwise direction. An axis of the swivel connector can be oriented to be inclined with respect to the longitudinal axis of the stem. This is because the swivel connector is maneuverable and can be oriented in relation to the stem. Since, the roller applying member is secured to the shaft of the swivel connector, the roller applying member rotate with swivel connector in the clockwise or counterclockwise direction about the axis of the stem, and oriented away from the longitudinal axis of the stem. The user can modify the angle formed between the longitudinal axis of the stem and the longitudinal axis of the swivel connector to make the swivel connector and the roller applying member off-axis to one side and the other of the axis of the stem.
Additionally, the swivel connector also allows the roller applying member to rotate degrees clockwise or counterclockwise about the shaft of the swivel connector. This may be desirable for precise application of cosmetic product. Therefore, the roller applying member and the swivel connector are connected in a manner that they are rotatable with respect to each other.
The rotation of the roller applying member with respect to the shaft is about an axis of rotation that is typically coincident with an axis of the shaft of the swivel connector.
In an embodiment of the disclosure, there is cooperation between the roller applying member and the shaft of the swivel connector, wherein the roller applying member forms a “hub”, and the shaft of the swivel connector forms a “spindle”. The roller applying member collaborates with the shaft while remaining free to rotate with respect to the shaft of the swivel connector.
Advantageously, the roller applying member, forming the hub, comprises a non-through cavity with an opening at a proximal end of the roller applying member.
The roller applying member, according to preferred embodiment has a substantially columnar body with rounded lower end. In other embodiments, the roller applying member may typically be external, cylindrical, tapered, or partially spherical, and will have a typically rounded lower end.
Typically, the roller applying member is connected to the shaft by a click fit or snap fitment means. The snap fitment means includes an annular protrusion formed on outer surface of the shaft and corresponding annular groove formed on an inner surface of the roller applying member.
According to the disclosure, the roller applying member may comprise a means of transferring or temporarily retaining the cosmetic product. This transfer or temporary retention means include flocking. In other embodiments, transfer or temporary retention means include may typically be chosen as either a brush provided with bristles, a cellular foam type material, a fibrous material such as felt or a woven or nonwoven a set of reliefs and recesses such as grooves or ribs formed on the said application means itself.
According to an aspect of the present disclosure, an outer surface of the roller applying member may be flocked with fibers. Briefly, the fibers for flocking which may be of any commonly used material, such as nylon, polyester, or any natural fiber are applied with an adhesive, such as an epoxy, to the surface to be flocked. The flocking finish to the outer surface of the roller applying member may be achieved by an appropriately chosen known technique, such as electrostatic flocking.
According to an alternate embodiment of the present disclosure, the roller applying member may or may not be flocked or partially flocked.
According to yet another aspect of the present disclosure, the roller applying member may include grooves, to provide a satisfactory load of the cosmetic product. In a preferred embodiment, the roller applying member includes two grooves, that make it possible to create product reserves on the application surface. At least one of the two grooves, extend one revolution around a longitudinal axis of the roller applying member. Thus, said least one of the two grooves, is an annular groove. In a preferred embodiment, the edges of the grooves and are mutually parallel.
In the preferred embodiment, the roller applying member includes four faces, namely, a first face, a second face, a third face, and a fourth face. The first face and the third face being opposing faces, and the second face and the fourth face being opposing faces. In this embodiment, both grooves, have a shared edge, with the lower edge of one groove serving as the upper edge of the other groove. Specifically, one groove is an upper groove, while the other groove is a lower groove.
Furthermore, the edges of the grooves and exhibit undulations, featuring a singular trough extending on one face of the roller applying member and a corresponding crest extending on the adjacent surface. Specifically, the edges of each of the two grooves, comprises a first trough on the first face, a first crest on the second face, a second trough on the third face, and a second crest on the fourth face. Consequently, the three troughs are present on the first and third opposing faces of the roller applying member, rendering these faces identical in appearance. Similarly, the three crests are present on the second and fourth opposing faces of the roller applying member, making these faces identical. In this embodiment, each of an upper and lower edge of the groove defines only a single crest or trough extends across the entire width of any given face of the roller applying member. However, in alternative embodiments, more than one crest and/or trough can be present on a single face of the roller applying member.
