This application claims benefit of Indian Provisional Application Ser. No. 201611029738, filed on Aug. 31, 2016, which is incorporated by reference in its entirety.
The subject of the present disclosure is an adjustable applicator for applying cosmetic, makeup, or personal care composition to keratin materials chosen from the skin, the lips and the eyelashes, or hair of the human. The cosmetic or care product includes products such as for mascara, lip stick, hair color, skin care and like products.
Various applicators for applying a substance are known. There are certain application areas where there is a requirement of curving the applicator as per user's convenience. Some such areas include application of mascara or in the cleaning of dental interstices.
Also, mascara, an important make-up accessory used to darken and define eyelashes to accentuate the eyes, is difficult to apply because of the target area of application. The eyelashes offer a very small application area, while being soft, flexible, delicate and in close proximity to very sensitive eye tissue. Therefore, a mascara product would be liked by the consumers when a right kind of applicator is provided to them for easy application as the overall consumer experience depends on both the product and on the applicator used to apply it.
Mascara applicators such as twisted wire mascara brushes and molded mascara applicators are known in the art. The flexibility and the bristle or tooth position characteristics of a majority of known mascara brushes or combs are fixed.
Also, mascara applicators should retain a sufficient quantity of mascara to avoid a need for overly-frequent re-loading during application. Further, such applicators should be able to grip the lashes, separate them, extend them and/or curl them, depending on the type of makeup desired. Users may find it difficult to control the quantity of substance loaded onto the brush or comb of known applicators.
U.S. Pat. Nos. 3,998,235 and 5,722,436 describe applicators comprising applicator elements with a separation that may be adjusted by the user. In such applicators, the distance between the applicator elements is modified by applying a compressive force along the longitudinal axis of the applicator. Further, U.S. Pat. No. 6,345,626 describes an applicator comprising a plurality of independent disks suitable for being axially pressed together while the applicator is being withdrawn from the receptacle containing the substance to be applied.
There exists a need, prior to application and/or during use, to be able to modify an applicator to adapt to the shape, number, disposition, thickness, flexibility, and length of eyelashes or eyebrows of a person, to the rheology of the substance, and/or to the desired type of makeup.
Accordingly, it is an object of the present disclosure to provide an adjustable applicator in which at least two distinct application methods which can be either combing or separating action can be adjusted to suit all users.
It is another object of the present disclosure to provide an adjustable applicator which enables a user to modify the spacing between application elements or feature bearing the application elements which will optimize the combing and separating action of the adjustable applicator.
To this end, the disclosure provides an adjustable applicator comprising an applicator head and wherein the applicator head is configured to adopt at least two configurations, namely a first configuration and a second configuration. In the first configuration, the applicator head is fully extended along a central longitudinal axis of the adjustable applicator and which also corresponds to a radially retracted position of at least one portion of the applicator head. The applicator head has a first diameter in the first configuration. In the second configuration, the applicator head is in a radially extended position, in which the at least one portion of the applicator head is radially deformed and overall height of the applicator head is altered. This produces a pronounced increase in the applicator head's diameter and the diameter alteration is at least at one point along a length of the applicator head. In the second configuration, the applicator head has second altered diameter which is distinct than the first diameter.
According to an aspect of the present disclosure, the applicator head comprises at least two applicator members. More particularly, the applicator head comprises a first applicator member and a second applicator member. According to a preferred embodiment, the first applicator member is an inner applicator member. Each of the at least two applicator members comprises a support body having an outer surface facing away from the central longitudinal axis. A plurality of application elements extend out from the outer surface of the support body of each of the at least two applicator members. Each of the first applicator member and a second applicator member comprises a distal end and a proximal end. When there is an axial displacement of one of the at least two applicator members, the other of the at least two applicator member is relatively deformed radially.
However, an embodiment where the applicator head comprises more than two applicator members is also contemplated.
According to an aspect of the present embodiment, one of the proximal ends and distal ends of the first applicator member and second applicator member do not have axial movement relative to each other, i.e. they are fixed to one another in such a manner that said ends of the first applicator member and second applicator member do not move independently of each other. However, other of the proximal and distal ends of the first applicator member and second applicator member have axial movement relative to each other. The first and second applicator members may be directly connected at their respective ends by screw, adhesive, bi-injection method or any other connecting means known in the art. In other alternate embodiments, the ends of the first and second applicator members may be indirectly connected to one another via a third part.
According to a preferred aspect of the present embodiment, the distal ends of the first applicator member and second applicator member do not have axial movement relative to each other, i.e. they are fixed to one another in such a manner that distal ends of the first applicator member and second applicator member do not move independently of each other. However, the proximal ends of the first applicator member and second applicator member have axial movement relative to each other, more particularly, the proximal end of the first applicator member is axially movable and the proximal end of the second applicator member is fixed so that it cannot move axially.
According to a further aspect of the present embodiment, the two applicator members are arranged to be movable relative to each other wherein the relative movement of the applicator members results in radial deformation of one of the applicator members. More specifically, when the first applicator member is moved axially towards the proximal end of the adjustable applicator, the distal end of the second applicator member is pulled along with the distal end of the first applicator member, however the proximal end of the second applicator member does not move, which results in radial deformation of the second applicator member due to compression stress exerted on it. Thus, the second applicator member is movable between a radially retracted position and a radially extended position. The second applicator member is in the radially extended position when the first applicator member is moved axially towards the proximal end of the adjustable applicator. The second applicator member is in the radially retracted position when the first applicator member is moved axially towards a distal end of the adjustable applicator.
According to another embodiment, at least a portion of the second applicator member is in the radially extended position when the first applicator member is moved axially towards the proximal end of the adjustable applicator.
According to an aspect of the present disclosure, the adjustable applicator comprises of an actuator, a cap, a hollow stem, a movable member, an inner rod and an applicator head.
According to an aspect of the present disclosure, the actuator causes the displacement of at least one applicator member relative to other applicator members and thereby varying the profile of applicator head of the adjustable applicator. The actuator is a dialer, however, the actuator may be a slider, a button or any other suitable actuator which is capable of exerting mechanical force through electronic or non-electronic means to cause axial movement of one of the at least two applicator members.
According to yet another aspect of the present disclosure, the support body of the second applicator member is tubular body with a hollow interior. Further, the support body includes at least two spaced slots extending substantially longitudinally thereon to define at least two longitudinal strips between them, and wherein the at least two longitudinal strips having plurality of application elements thereon. The at least two longitudinal strips are arranged along the central longitudinal axis but in other alternate embodiments, the at least two longitudinal strips may be arranged at an angle with the central longitudinal axis or may form a spiral around the central longitudinal axis.
According to another embodiment, the second applicator member is made up of two material having different physical properties or chemical properties for e.g.: a portion of the second applicator is made up of soft material and a portion of the second applicator is made up of hard material.
According to another embodiment, at least a portion of at least one strip of the second applicator member is made of a material softer/flexible than material of other portion of the strip. The softer/flexible portion of the strip of the second applicator member is in the radially extended position when the first applicator member is moved axially towards the proximal end of the adjustable applicator.
According to yet another aspect of the present disclosure, the first applicator member is mounted at least in part within the hollow interior of the second applicator member so as to expose the application elements of each of the first and second applicator members. More specifically, the first applicator member has an elongated body having a proximal end and a distal end. The first applicator member further comprises at least two longitudinal projecting strips projecting from the elongated body, and wherein each longitudinal projecting strip has at least one row of the application elements thereon. The at least two longitudinal projecting strips are arranged along the central longitudinal axis but in other alternate embodiments, the at least two longitudinal projecting strips may be arranged at an angle with the central longitudinal axis or may form a spiral around the central longitudinal axis.
The projecting strips have a shape corresponding to the slots of the second applicator member so that when the first applicator member is mounted at least in part within the hollow interior of the second applicator member, the projecting strips are placed in the respective slots such that projecting strips of the first applicator member and the strips of the second applicator member together form an outer applicator surface of the applicator head corresponding to the first configuration of the applicator head.
According to yet another aspect of the present disclosure, the applicator members are so arranged to expose the application elements of each of the first and second applicator member in an alternate fashion, i.e. at least one row of application elements of the first applicator member are placed adjacent to at least one row of application elements of the second applicator member in alternate fashion. In other words, the strips of the second applicator member alternate with projecting strips of the second applicator member around the central longitudinal axis of the applicator head.
This embodiment may, of course, be subject to many variations. Thus, the number of strips of the second applicator member may be higher than two, for instance, three, four, five, six, eight or any other number. The shape and disposition of the application elements can obviously be altogether different.
According to yet another aspect of the present disclosure, the application elements may be chosen from a group of application elements consisting of bristles, teeth, discs, ribs, and flocking.
According to yet another aspect of the present disclosure, at least one strip of the second applicator member is movable from a radially retracted position to a radially extended position. The radial gap is created between the first and second applicator members in the radially extended position of the second applicator member. In other words, the at least one strip of the second applicator member is relatively deformed radially outward to separate from the strip of the first applicator member in the radially extended position.
According to preferred embodiment, the second applicator member is made of material softer than the material of first applicator member. Preferably, the second applicator member is flexible and made of an elastomeric material. The first applicator member may be made from a harder plastic, metal, ceramic or similar type of material.
According to yet another aspect of the present disclosure, the proximal end of the first applicator member is connected to a distal end of the axially movable inner rod of the adjustable applicator. Whereas, the proximal end of the second applicator member is fixed to a distal end of the hollow stem of the adjustable applicator and wherein the stem is not axially movable. The hollow stem includes a cavity which houses the inner rod. The adjustable applicator also includes the actuator and the movable member and wherein, the rotation of actuator causes the axial displacement of the movable member. According to an embodiment, the actuator is a dialer but in other embodiments, the actuator may be a slider, a button or any other suitable actuator which causes axial movement of the first applicator member.
According to present embodiment, the cap is attached with the actuator such that the actuator is free to rotate with respect to the cap via a snap-fit system comprising an internal annular groove on the actuator that engages with a complementary external annular protrusion on the cap. The actuator can thus be turned by the user relative to the cap. However, any suitable engagement means may be employed that allows relative rotation between the actuator and cap.
Further, the lower portion of the cap is non-rotatably connected to a proximal portion of the stem. The stem may be attached to the cap of a gripping member by snap-fitment or by any other engaging means known in the prior art. Further, for non-rotatably locking the stem with the cap, there may be provided on the interfaces where the stem is joined to the cap, complementary longitudinal protrusions and positioning longitudinal grooves. For example, the outer surface of stem may include a plurality of longitudinal protrusions which is arranged to become in mating engagement with complementary grooves present at an inner surface of the cap or vice versa, for non-rotatable engagement. However, it is not beyond ambit of the present disclosure that any other non-rotatable engagement known in the art may be employed for locking any relative rotation between the stem and the cap. According to alternate embodiments, the stem and the cap may be integrally molded.
According to yet another aspect of the present disclosure, the movable member is rotatably connected to the cap by a threaded arrangement. The upper portion of the cap includes internal threads to connect to outer threads of the movable member. Movable member is connected to the actuator in a manner such that axial movement of the movable member is allowed but rotational movement with respect to actuator is prohibited. The actuator includes longitudinal guide protrusions at its inner surface for guiding axial movement of the movable member and for preventing movable member from rotating with respect to actuator, when the actuator is rotated. The movable member includes a catch which holds a proximal end of the inner rod. When the actuator is rotated, the movable member rotates with respect to cap and move axially due to screw engagement with the cap. The inner rod and the first applicator member are also displaced axially with movable member since inner rod is held by the movable member. Thus, when the actuator is actuated by rotation in first direction about a longitudinal axis, the movable member also rotates along with the actuator and moves up on the threads of cap and thereby results in the upward movement of the inner rod in the longitudinal direction. The movement of inner rod in the longitudinal direction results in the displacement of the first applicator member in the longitudinal direction, and the first applicator member is pulled along with the distal end of the second applicator member to decrease the overall height of the applicator head and which also results in radial extension/blowing of the second applicator member and producing a pronounced increase in the applicator head's diameter. The applicator head achieves the second configuration which corresponds to radially extended position of the second applicator member. The application in this state of the applicator head gives a better separation and curling in case of mascara. The actuator when rotated in a second direction reverse to first direction brings the applicator head to its initial first configuration which corresponds to radially retracted position of the second applicator member. It will thus be understood that the applicator may be used by a person either in the minimum diameter configuration or in the maximum diameter configuration. If the user wishes to return from the radially extended position to that of radially retracted position, the user only has to rotate the actuator so that the inner rod moves downwards and the second applicator member resume its elongated and radially retracted position with initial diameter.
According to another aspect of the present disclosure, the inner rod is connected to the movable member in such a way that when the movable member rotates the inner rod does not rotate along with the movable member.
According to another aspect of the present disclosure, the inner rod is connected to the movable member in such a way that when the movable member rotates the inner rod also rotate along with the movable member.
According to yet another aspect of the present disclosure, the inner rod and first applicator member may be formed integrally.
According to yet another aspect of the present disclosure, the stem and second applicator member may be formed integrally.
According to another aspect of the present disclosure, when the actuator is rotated with respect to the cap, the inner rod moves longitudinally with respect to the stem which cause variation in the profile of the applicator head as explained above. When a suitable adjustment of the profile of the applicator head has been made it will be retained while the applicator head is used. The adjustment is retained until the user intentionally rotates the actuator and the cap with respect to each other once again to achieve a different adjustment.
According to yet another embodiment of the present disclosure, the inner rod and the stem may have circular or non-circular transverse cross-sections.
According to yet another embodiment of the present disclosure, one or more annular ribs and sealing O-rings are configured around the inner rod so that the inner rod interfaces tightly against an inner wall of the stem. The annular ribs and the sealing O-rings prevent the product from leaking and ensure steady, smooth, and noiseless extension of the inner rod along the stem.
According to yet another aspect of the present disclosure, at least one longitudinal strip of the second applicator member includes at least one protrusion that projects in the adjacent slot of the second applicator member. A compression stress is exerted on the second applicator member when the first applicator member is displaced axially towards the proximal end of the adjustable applicator, a mechanical interference between the first and the second applicator member is generated due to interference between the at least one protrusion and the projecting strip of the first applicator member. The mechanical interference produces a resultant force in radial direction on the second applicator member, which guarantees the separation between the longitudinal strips of the second applicator member and the projecting strips of the first applicator members in radial orientation/direction in spite of being impregnated by a cosmetic product. In the first configuration, the at least one protrusion is located below a proximal end of one of the at least two longitudinal projecting strips of the first applicator member; and in the second configuration of the applicator head, the at least one protrusion is located laterally to the at least two longitudinal projecting strips of the first applicator member.
According to yet another aspect of the present disclosure there is provided a container comprising a receptacle and the adjustable applicator as described above. The receptacle is of cylindrical cross section extending in the longitudinal direction; however, the receptacle can take any suitable shape. The receptacle is closed by the cap by way of a threaded arrangement; however, any other suitable lock and key arrangement may be used to close the receptacle. The actuator, the cap, and the receptacle are of substantially same cross section so as to align along a common axis when fastened to each other in the closed position of the container.
The applicator member is secured to the stem and intended for being inserted in said receptacle in order to be loaded with the product to be applied.
The receptacle has a closed end and an open end in the form of a neck thereby defining a cavity for holding the product. The neck of the receptacle is provided with an external thread intended for cooperating with a complementary internal thread carried by a cap in its lower portion, allowing the receptacle to be closed by screwing.
According to yet another aspect of the present disclosure, for some cosmetic products, such as mascara or a lip gloss, it is preferable to provide a wiper positioned into the neck of the receptacle to wipe excess product from the adjustable applicator as the adjustable applicator is withdrawn from the receptacle. The wiper is preferably made of an elastomeric plastic material. The wiper may be one time snap fitted to the neck of the receptacle, however, the wiper may be fitted onto the neck of the receptacle by any other suitable arrangement.
According to an alternate embodiment of the present disclosure, both the applicator members may blow relative to each other and wherein one of the applicator members may blow more relative to other applicator member.
A user may utilize the container as described in above embodiments for application of a product. Moreover, the adjustable applicator of the container allows the user to vary the profile of the applicator head.
The materials suitable for forming the receptacle, the inner rod, the cap, actuator, stem and the movable member may be formed of plastic material such as polypropylene, acrylonitrile butadiene styrene, polyacetal or any other suitable polymeric material. In alternate embodiments, the receptacle may be made of glass or metal. In alternate embodiments, the inner rod may be made of metal, alloy or ceramic material. The material for forming wiper could be low-density polyethylene. The aforementioned materials for forming various parts of the container of the present disclosure are an example, however other suitable materials may also be used. Depending upon the substance being used in the receptacle, a variety of sizes and shapes of the applicator heads/members can be utilized. It could have a shape other than cylindrical such as ovular, tapered or any other suitable shape.
