Device for applying and removing nail polish

Abstract

A device for applying or removing nail polish or nail art has a replaceable cartridge with a distal end removably coupleable to a proximal end of a handle. The cartridge has a reservoir that contains a liquid, such as nail polish or nail polish remover and a flow control member (e.g., valve) actuatable to allow flow of the liquid out of the distal end of the cartridge. The handle has a flow path therethrough that extends between its proximal end to an applicator implement (e.g., brush, sponge) attached to its distal end, the flow path in fluid communication with the flow control member when the cartridge is coupled to the handle. Selective actuation of the flow control member by the user (e.g., by squeezing the cartridge) allows fluid to flow out the reservoir and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.

Description

BACKGROUND

Field

Aspects of the present disclosure are directed to a device for applying and removing nail polish and/or nail art.

Description of the Related Art

Nail polish applicators are usually provided within the bottle containing the nail polish (e.g., attached to a stem that extend from the underside of the cap of the bottle. However, such applicators have several draw backs. For example, they are only associated with the particular liquid (e.g., nail polish) in the corresponding bottle. Additionally, the whole applicator is inserted into the bottle, not just the brush at the end of the stem, there may inadvertent dripping of nail polish. More recently, applying nail art has become popular, which can include applying a variety of colors, glitters, patterns and/or textures.

Further, to remove nail polish, a separate applicator is used to apply the remover (e.g., acetone, ethyl acetate).

SUMMARY

Accordingly, there is a need for an improved device for applying and removing nail polish, nail art, etc. to and from nails. Disclosed herein are embodiments of applicator designs that can be utilized to apply and/or remove nail polish and nail art from a user's nails. Advantageously, the applicator designs overcome at least some of the drawbacks of existing applicators discussed above.

In accordance with one aspect, a device for applying or removing nail polish or nail art on a finger or toe nail is provided. The device comprises a cartridge of resilient material having a reservoir therein that contains a fluid chosen from a group consisting of nail polish or nail polish remover. The cartridge is configured to allow flow of the fluid through a flow control member proximal a distal end of the cartridge. The device also comprises a handle extending between a proximal end and a distal end, the proximal end of the handle configured to removably couple to the distal end of the cartridge. The handle has a flow path that extends between the proximal and distal ends of the handle and is in fluid communication with the flow control member when the cartridge is coupled to the handle so that flow of fluid from the reservoir is configured to flow through the flow path in the handle. The device also comprises an applicator head having a support base attached to the distal end of the handle and an applicator implement at a distal end of the applicator head. The support base has a flow path that extends through the support base to the applicator implement and is in fluid communication with the flow path in the handle so that flow of fluid through the handle flows through the support base to the applicator implement. Selective actuation of the cartridge or handle by the user allows a volume of fluid to flow out the cartridge through the flow control member and into the flow path in the handle, said fluid flowing from the handle though the flow path in the support base to the applicator implement for application of the fluid by the user to a finger or toe nail.

In another aspect a device for applying or removing nail polish or nail art on a finger or toe nail is provided. The device comprises a cartridge of resilient material having a reservoir therein that contains a fluid chosen from a group consisting of nail polish or nail polish remover. The cartridge has a concave contoured top surface configured to receive a user's finger thereon and a convex contoured bottom surface configured to receive a user's finger thereon, the cartridge having a valve actuatable to allow flow of the fluid out of a distal end of the cartridge. The device also comprises a handle extending between a proximal end and a distal end, the proximal end of the handle configured to removably couple to the distal end of the cartridge. The handle has a contoured body comprising a contoured top surface that substantially aligns with the concave contoured top surface of the cartridge. The handle also has a contoured bottom surface that substantially aligns with the convex contoured bottom surface of the cartridge so that the handle and cartridge together define a contoured body that facilitates the holding of the cartridge and handle by the user. The handle has a flow path that extends between the proximal and distal ends of the handle and is configured to receive the fluid dispensed via the valve when the cartridge is coupled to the handle, an applicator implement operatively coupled to the distal end of the handle so that flow of fluid through the handle flows to the applicator implement. Selective actuation of the cartridge by the user allows a volume of fluid to flow out the cartridge through the valve and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.

In accordance with another aspect, a kit for applying or removing nail polish or nail art on a finger or toe nail is provided. The kit comprises one or more replaceable cartridges of resilient material having a reservoir therein that contains a fluid chosen from a group consisting of nail polish or nail polish remover. Each cartridge has a concave contoured top surface configured to receive a user's finger thereon and a convex contoured bottom surface configured to receive a user's finger thereon. Each cartridge has a flow control member actuatable to allow flow of the fluid out of a distal end of the cartridge. The kit also comprises a handle having a contoured body extending between a proximal end and a distal end, the proximal end of the handle configured to removably couple to the distal end of the cartridge. The handle has a flow path that extends between the proximal and distal ends of the handle and is in fluid communication with the flow control member when the cartridge is coupled to the handle so that flow of fluid from the reservoir is configured to flow through the flow path in the handle. An applicator implement is operatively coupled to the distal end of the handle so that flow of fluid through the handle flows to the applicator implement. The one or more replaceable cartridges are each configured to removably couple to the proximal end of the handle, and wherein selective actuation of the cartridge by the user allows a volume of fluid to flow out the cartridge through the flow control member and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.

DETAILED DESCRIPTION

Disclosed herein are several embodiments of a device (e.g., tool) for applying and/or removing nail polish and/or nail art (e.g., applicator device). The device can be handheld. In some embodiments, the same device can be used for application of one or more substances (e.g. nail polish, paint, glitter, nail art) as well as for the removal of said one or more substance (e.g., via application of nail polish remover). The applicator device can have shapes other than the shapes described below. The applicator device can be made of any suitable material (e.g., plastic, metal, etc.). The applicator can be made via using a suitable process, such as molding, casting, etc.

FIGS. 1-8 shows an applicator device 100 for applying a substance (e.g., nail polish, nail art, nail polish remover) to a nail (finger or toe nail) of a user's finger(s) and/or toe(s). The device 100 can have extend between a proximal end 2 and a distal end 4. The device 100 has a reservoir 10 at the proximal end 2, an applicator head 60 at the distal end 4, and a handle 40 interposed between the reservoir 10 and the applicator head 60. Optionally, a cap 80 can removably cover the applicator head 60.

The reservoir 10 can hold a substance (e.g., nail polish, nail polish remover, nail art, etc.) that can be delivered through the handle 40 to the applicator head 60 for application on a user's finger and/or toe nails. Optionally, the reservoir 10 can be in a detachable cartridge 20 that removably couples to a proximal end 42 of the handle 40, as further described below. Alternatively, the reservoir 10 and handle 40 can be a single piece (e.g., monolithic, seamless piece). Optionally, the head 60 can removably couple to a distal end 44 of the handle 40, as further described below. Alternatively, the handle 40 and applicator head 60 can be a single piece (e.g., monolithic, seamless piece). In one variation, the reservoir 10, handle 40 and head 60 are a single piece (e.g., monolithic, seamless piece). In another variation, at least one of the reservoir 10 and applicator head 60 are removably coupleable to the handle 40. In another variation, both the reservoir 10 and applicator head 60 are removably coupleable to the handle 40. Optionally, the reservoir 10 is refillable (e.g., via a removable cap, or via the flow control member 30) by a user.

As best shown in FIG. 7, in one variation the reservoir 10 is defined in a detachable cartridge 20 that removably couples to the proximal end 42 of the handle 40. The cartridge 20 optionally has a contoured body that extends between a proximal end 22 and a distal end 24. Optionally, the proximal end 22 is curved and the distal end 24 has an opening 25 sized to receive a lip 43 of the proximal end 42 of the handle 40. The cartridge 20 optionally has a contoured (e.g., concave) top surface 26 and a contoured (e.g., convex or domed) bottom surface 28 that advantageously allows a user to comfortable hold the cartridge, on its own or when attached to the handle 40. Advantageously, the contoured (e.g., concave) top surface 26 can optionally receive the user's thumb thereon and the contoured (e.g., convex, domed) bottom surface 28 can optionally receive one or more of the user's index, middle and ring fingers thereon, allowing the user to comfortably hold the cartridge in their hand (e.g., with the index, middle and/or ring fingers flexed so that the fingers contact a greater surface area of the bottom surface 28). Additionally, the curved proximal end 22, can optionally comfortably fit against the user's palm while holding the cartridge with their hand.

Optionally, the cartridge 20 removably couples to the handle 40 via a press-fit connection. In another variation, the cartridge 20 can removably couple to the handle 40 via a threaded connection. In still another variation, the cartridge 20 can removably couple to the handle 40 via a key-slot connection. In still another variation, the cartridge 20 can removably couple to the handle 40 via a snap-fit mechanism; for example, one of the distal end 24 of the cartridge 20 and the proximal end 42 of the handle 40 can have a ridge or protrusion that snaps or clips into a groove or recess on the other of the distal end 24 of the cartridge 20 and the proximal end of the handle 40.

Optionally, the cartridge 20 has a window 31, allowing the user to view the inside of the reservoir 10. The window advantageously allows the user to readily identify the contents in the reservoir 10 (e.g., the color nail polish, type of nail art, etc.). Additionally, the window 31 allows the user to readily identify the level of fluid in the reservoir 10 and determine whether its contents are almost depleted such that a change in cartridge will be required.

With continued reference to FIG. 7, the distal end 24 of the cartridge 20 can have a recess 29 that is at least partially defined by the opening 25, and can have a flow control member 30 disposed in the recess 29. Optionally, the flow control member 30 includes a flow control valve (e.g., one-way valve, needle valve, check valve, flap valve) that selectively allows the liquid (e.g., nail polish, nail art, nail polish remover) to flow from the reservoir 10 through the flow control member 30 and into the handle 40, as further described below. For example, the flow control member 30 can be made of a flexible material (e.g., rubber, plastic) and have one or more walls with a flap valve defined therein so that when the cartridge 20 is squeezed, the flow control member 30 is flexed and the flap valve opens to allow flow from the reservoir 10 therethrough, and when the cartridge 20 is not squeezed the flow control member 30 can unflex to its default orientation with the flap valve closed to inhibit flow from the reservoir 10. Optionally, the flow control member 30 can be moved from a closed position that inhibits flow from the reservoir 10 to an open position that allows flow from the reservoir 10. Optionally, the flow control member 30 is spring loaded and biased toward the closed position. Optionally, when the cartridge 20 is coupled to the proximal end 42 of the handle 40, a feature in the handle can press against the flow control member 30 to move it to the open position to allow flow of liquid from the reservoir 10 into the handle 40. In another variation, the flow control member 30 can include a button that can be pressed by a user, or pivotable lever that can be pivoted between two or more positions by the user, or slidable tab that can be slid between two or more positions by the user, on one of the cartridge 20 and handle 40 that can be selectively actuated by the user to open or close the reservoir 10 to fluid flow. In one variation, an actuator (e.g., on the handle 40) can be actuated (e.g., depressed, slid, pivoted) to eject the cartridge 20 from the device 100.

Optionally, the flow control member 30 can have a flow metering control that allows a predetermined amount of fluid to flow from the reservoir 10. In one variation, the flow control member 30 can include a check valve or one-way valve or flap valve that can be actuated by the user. For example, the user can squeeze the cartridge 20 (e.g., press on the top surface 26 and bottom surface 28 with their fingers), which can cause a flexible check valve or one-way valve to one to allow fluid flow from the reservoir 10 (e.g., as long as the cartridge 20 is squeezed). Once the user stops squeezing the cartridge 20, the flexible check valve or one-way valve can move to a closed position to disallow further flow from the reservoir 10 (e.g., until the cartridge 20 is squeezed again).

With continued reference to FIGS. 1-8, the handle 40 optionally has a contoured body that extends from its proximal end 42 to its distal end 44. The handle 40 has a top surface 46, at least a portion of which is optionally contoured (e.g., concave) and has a contoured (e.g., convex or curved) bottom surface 48. Advantageously, the top surface 46 of the handle aligns with the top surface 26 of the cartridge 20 to provide a substantially continuous surface (e.g., a continuous surface that substantially defines a circular surface, as shown in FIG. 5). Similarly, the bottom surface 48 of the handle aligns with the bottom surface 28 of the cartridge to provide a substantially continuous surface (e.g., a continuous surface that substantially defines a domed surface, as shown in FIGS. 3-4). Accordingly, when assembled together, the cartridge 20 and handle 40 advantageously provides a contoured body that is easy and comfortable for the user to hold (e.g., while applying nail polish to a nail of the user or a different person) and the junction or transition between the cartridge 20 and handle 40 is substantially smooth to inhibit discomfort to the user or potentially cause the user to inadvertently push or pry the handle 40 away from the cartridge 20, inadvertently decoupling them. As best shown in FIGS. 3 and 5, the cartridge 20 can have a maximum width W1 that is greater than a maximum width W2 of the handle 40. Optionally, the handle 40 has a conduit or flow path 49 that extends between the proximal end 42 and distal end 44 of the handle 40. The conduit or flow path 49 substantially aligns with the flow control member 30 of the cartridge 20 to receive liquid from the reservoir 10 therethrough. Accordingly, once the cartridge 20 is coupled to the handle 40, the liquid in the reservoir 10 can flow to the distal end 44 of the handle 40 via the conduit or flow path 49.

With reference to FIG. 7, the applicator head 60 optionally includes a support body 62 attached to the distal end 44 of the handle 40, and an applicator implement 64 attached to the support body 62.

Optionally, the applicator head 60 can be removably coupled to the distal end 44 of the handle 40 (as shown in FIG. 8), allowing different applicator head 60 (e.g., having different types applicator implements 64, different widths of applicator implements 64, different lengths of applicator implements 64, etc.) to be coupled to the handle 40 to customize the device 100 and its operation. Optionally, the head 60 removably couples to the handle 40 via a press-fit connection. In another variation, the head 60 can removably couple to the handle 40 via a threaded connection. In still another variation, the head 60 can removably couple to the handle 40 via a key-slot connection. In still another variation, the head 60 can removably couple to the handle 40 via a snap-fit mechanism; for example, one of the distal end 44 of the head 40 and the support body 62 can have a ridge or protrusion that snaps or clips into a groove or recess on the other of the distal end 44 of the head 40 and the support body 62.

In FIG. 7, the applicator implement 64 is a brush having a plurality of bristles. In another variation, the applicator implement 64 is a sponge. However, the applicator implement 64 can have other forms (e.g., a pen, a stamper tip for applying stamped designs, a striper tip for applying stripes, a dotter tip for applying dots) that can optionally be removably coupled to the distal end 44 of the head 40 as desired to allow a user to create (e.g. draw) nail art designs on their finger or toe nails. In some variations, the applicator head 60 can be interchanged while the cartridge 20 is loaded (e.g., coupled) to the handle 40. In other embodiments, the applicator head 60 can be interchanged prior to coupling a cartridge 20 to the handle 40.

The applicator head 60 can have a conduit or flow path 66 (See FIG. 6) that extends through the support body 62 to the applicator implement 64. The conduit or flow path 66 substantially aligns with the conduit or flow path 49 in the handle 40, so that the liquid (e.g., nail polish, nail art, nail polish remover) that flows through the handle 40 from the reservoir 10 flows to the applicator implement 64 (e.g., brush, sponge) via the conduit or flow path 49 in the handle and the conduit or flow path 66 in the applicator head 60. Accordingly, once the cartridge 20 is coupled to the handle 40, and the flow control member 30 is actuated as described above, the liquid in the reservoir 10 can flow to the applicator implement 64 for application by the user (e.g., to a finger or toe nail).

FIG. 9 shows one embodiment of a kit 200. The kit 200 can include a case with one or more cartridges 20, each having a different fluid (e.g., color nail polish, nail polish remover, nail art) in its reservoir 10, one or more handles 40, and one or more applicator heads 60 with at least two different applicator implements 64 (e.g., sponges, brushes, pens, stamper, dotter, stripper). In some variations, the kit 200 can have only cartridges 20, or only applicator heads 60. A user can then assemble the device 100 by coupling one of the cartridges 20 and one of the applicator heads 60 to the handle 40 to assemble the applicator devices 100, such as the applicator devices described above. The kit can also include one or more (e.g., a plurality) of cartridges 20.

Advantageously, the removable and replaceable cartridges 20 allow the user to utilize a variety of different nail polishes utilizing the same handle 40 and/or applicator head 60 to creatively apply different designs to a finger or toe nail in one sitting, therefore making the process more efficient and avoiding stains (e.g., from dripping nail polish in conventional nail polish bottles). Additionally, the system described herein advantageously allows the user to readily couple and decouple different cartridges (having different color nail polish or art, such as glitter) with a handle having different applicator implements (e.g., brush tip, sponge tip, stamper tip, striper tip, dotter tip) in one sitting to apply complex creative designs to a user's nails, making the process more efficient. In one variation, different applicator implements can be removably coupleable to the handle, so that the user can customize the applicator device utilizing different applicator implements and different cartridges as required by the desired nail art design.
