Description
FIELD OF THE DISCLOSURE

The invention relates to a dermaplaning device, and more particularly a curved blade dermaplaning device. More particularly, this invention allows users to safely and effectively scrape curved areas on the epidermis to create a variety of cosmetic benefits for the skin. Dermaplaning helps to smooth skin, exfoliate the skin, reduce the appearance of wrinkles and scars, promotes the productions of collagen and elastin, and to clean the skin.


BACKGROUND

Various processes are known for treating facial skin. These processes are known to include hand-held devices and fall into several categories as follows: shaving, cleansing and moisturizing, dermabrasion, dermaplaning (exfoliation), and debridement. Of these categories, dermaplaning is a relatively popular process that is relatively simple and safe and is used for exfoliating the epidermis, i.e., an outer layer of cells in the skin, and removing fine vellus hair, i.e., “peach fuzz,” from the skin. Dermaplaning is a process normally performed by licensed skin care professionals, such as estheticians, because of the use of a surgical scalpel or similar blade to exfoliate the epidermis. Using a straight edge scalpel and a delicate touch, the scalpel is swept across the skin with light feathering strokes to exfoliate the skin to remove the oldest dead skin cells on the skin's outermost surface. Such scalpels are not available for non-professional use. As such, dermaplaning is only available at spas with licensed skin care professionals. Such dermaplaning treatments at spas can be relatively expensive.


Dermaplaning facial skin has many benefits. For example, removing epidermal skin allows skin care products to penetrate more readily into deeper layers of the skin for better results. As mentioned above, dermaplaning removes vellus hair which tends to cause a build-up of dirt and oils in the follicles. Removal of the hair results in healthier looking skin. Unfortunately, all known dermaplaning devices rely on a straight blade to remove the vellus hair, which work best on flat regions of the epidermis. However, most of the face (as well as other surfaces on the body) is curved and contoured such that the user must awkwardly manipulate the straight blade of the dermaplaning device in order to remove the vellus hair from these curved regions.


Accordingly, there exists a need for a curved blade dermaplaning device that addresses or solves at least the issues mentioned herein.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present disclosure will now be described more fully hereinafter with reference to exemplary embodiments thereof. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural variations unless the context clearly dictates otherwise.


A curved blade dermaplaning device as disclosed herein may be used to “dermaplane” or scrape an exterior surface of an object to remove any debris, fibers, hairs, etc., in order to leave the exterior surface smooth. In some example embodiments, the object is a mammalian user and the exterior surface is the exposed skin and, more particularly, the epidermis of the mammalian user, such that the curved dermaplaning device may be used to scrape or skim the epidermis of the user to create a variety of cosmetic benefits for the skin. For example, using the curved dermaplaning device disclosed herein on the epidermis of a mammalian user advantageously smooths at least the epidermis layer of the skin, exfoliates the epidermis, reduces the appearance of wrinkles and scars in the skin, promotes the production of collagen and elastin in the skin, and cleans the epidermis, among other benefits.


Turning now to FIG. 1, a first example embodiment of a curved blade dermaplaning device 100 is disclosed. FIG. 1 illustrates a curved blade dermaplaning device 100 comprising a handle 102 and a curved blade assembly 104 including a blade housing 106, a blade 108, and a first and a second blade guard 110, 112 in a non-coplanar configuration. The handle 102 has a first portion 114 (see FIG. 2A) and a second portion 116 defining a gripping region 118. The curved blade assembly 104 may be engageable with or coupled to the first portion 114 of the handle 102. In some example embodiments, the curved blade assembly 104 and the handle 102 are integrally formed as a single unit with one another, such that the curved blade assembly 104 and the handle 102 are formed as one. In this example embodiment, the first portion 114 of the handle 102 and the blade housing 106 are fixedly engaged with or coupled to one another or otherwise formed such that they may be considered the same component with a seamless transition between the two. In other example embodiments, the curved blade assembly 104 and the handle 102 are separable and removable from one another so that the handle 102 is reusable with a replacement curved blade assembly 104. In this example embodiment, the first portion 114 of the handle 102 removably engages with or couples to the blade housing 106 of the curved blade assembly 104 via screw-fit engagement, press-fit engagement, magnetic engagement, and the like.


One example embodiment of an attachable/detachable handle 102 and curved blade housing 106 is shown in FIGS. 2A and 2B, respectively. As shown in FIG. 2A, for example, the first portion 114 of the handle 102 may define a protrusion 120 with a locking member 122 extending therefrom, while in FIG. 2B, the blade housing 106 of the curved blade assembly 104 may define a cavity 124 having a first and second opening 126, 128. The first opening 126 may be oriented about a central axis of the blade housing 106 and sized and shaped to receive the protrusion 120 with the locking member 122 when the curved blade assembly 104 is engaged with the handle 102. The second opening 128 may be defined on a lateral side of the blade housing 106 and in communication with the first opening 126. Upon alignment of the protrusion 120 with the locking member 122 with the first opening 126, the protrusion 120 with the locking member 122 may be inserted into the first opening 126. The handle 102 may then be twisted or rotated clockwise to rotate the protrusion 120 with the locking member 122 within the cavity 124 such that the locking member 122 is rotated into the engagement with the second opening 128 and thus securely retained in place. Pressure applied to the locking member 122 within the second opening 128 and simultaneous rotation of the handle 102 counter-clockwise may cause the locking member 122 to disengage from the second opening 128 so that the protrusion 120 and the locking member 122 may then be removed from the first opening 126, and the handle 102 thereby disengaged from the blade housing 106 of the curved blade assembly 104.


One or both of the handle 102 and the blade housing 106 may be formed as a molded plastic, or otherwise be a composite of plastic materials, metallic materials, wood, stone or other natural materials, recycled materials (either partially or completely), waste materials such as husks or shells from nuts, natural or man-made fibers, or any combination thereof. The gripping region 118 of the second portion of the handle 102 may be formed as an overmolded elastomeric component that prevents sliding of the user's hand during use of the curved blade dermaplaning device 100. The gripping region 118 may comprise a similar material or a different material than the material of the first portion 114 and/or second portion 116 of the handle 102. For example, the gripping region 118 may comprise elastomeric materials, metallic materials, or any combination thereof, and may have a textured surface or comprise additional materials having a lower durometer or higher coefficient of friction than the rest of the handle 102 so as to reduce slippage. The material of the gripping region 118 may be in the form of a continuous region, or may be in the form of a pattern of discrete grips that form the gripping region 118 when viewed in their totality.


A longitudinal axis may extend along a length of the handle 102 defined between the first portion 114 and the second portion 116. When engaged, the curved blade assembly 104 may be offset from the longitudinal axis and the second portion 116 of the handle 102, or the handle 102 and the curved blade assembly 104 may be in alignment along the longitudinal axis. As shown in FIG. 1, the curved blade assembly 104, and specifically the blade housing 106, is longitudinally offset from the second portion 116 of the handle 102. As used herein, “longitudinally offset” refers to the curved blade assembly 104 being angled (e.g., about 25 degrees) relative to the longitudinal axis of the handle 102. This advantageously allows a user to grip the gripping region 118 formed on the second portion 116 of the handle 102 without having the user's grip brush against the exterior surface of the object on which the curved blade dermaplaning device 100 is being used.


The blade housing 106 may define two portions 130, 132. A first portion 130 of the blade housing 106 may be configured for attaching to the first portion 114 of the handle 102. A second portion 132 of blade housing 106 may form an arcuate shape along its length defined between first and second ends of the second portion 132, the second end of the second portion 132 being arranged between the first end and the first portion 130 of the blade housing 106 (i.e., the second portion 132 of the blade housing 106 is curved). In some example embodiments, the arcuate shape defines a degree of curvature. The degree of curvature of the arcuate shape is based on the premise that the arcuate shape follows a curve of a corresponding circle, with a known radius. In some example embodiments, the radius may be between about two inches and about six inches, and preferably about four inches. Other radii may also be considered. Based on the known radius, the degree of curvature may be determined using standard geometric formulae. In some example embodiments, the degree of curvature using a radius of between about two inches and about six inches may be between about 30 degrees and about 40 degrees, and particularly between about 36 degrees and 37 degrees where a four inch radius is used. However, the entirety of or one or both of the first portion 130 and second portion 132 of the blade housing 106 may also be linear, or otherwise shaped. As shown in FIG. 1, for example, the second portion 132 of the blade housing 106 forms an arcuate shape defining a degree of curvature of about 36.42 degrees.


Referring now to FIG. 3, which is a perspective side view of the device in FIG. 1, the blade housing 106 is engaged with or coupled to the handle 102 without the blade 108 or first and second blade guards 110, 112. The blade housing 106 may define a recess 134 for fixedly or removably engaging the blade 108 and the first and/or second blade guard(s) 110, 112. The recess 134 may extend longitudinally relative to the blade housing 106 and be shaped and sized so as to removably or permanently engage the blade 108 and the first and/or second blade guard(s) 110, 112. The blade housing 106, the blade 108, and the first and/or second blade guard(s) 110, 112 may be integrally formed as a single unit, i.e., the blade housing 106 is molded over the blade 108 and the first and/or second blade guard(s) 110, 112, or the blade 108 and the first and/or second blade guard(s) 110, 112 are attachable to and removable from the recess 134 of the blade housing 106. Where the blade and the first and/or second blade guard(s) 110, 112 are removable relative to the blade housing 106, an engagement mechanism (not shown) may be provided about the curved blade dermaplaning device 100 (e.g., about the handle 102 or the blade housing 106) to allow for engagement and disengagement of the blade 108 and the first and/or second blade guard(s) 110, 112 from the recess 134. In this example embodiment, the blade 108 and the first and/or second blade guard(s) 110, 112 may be engageable with the blade housing 106 through one or more mechanisms, such as magnets, a press fit, a snap fit, a twist lock, a biased lock, or combinations thereof.


In some example embodiments, a release button (not shown) may be provided adjacent to the recess 134 near the blade housing 106 or the handle 102. The release button may be slideable in a parallel direction relative to the recess 134, the blade housing 106, and/or handle 102 from an initial position in which the blade 108 and the first and/or second blade guard(s) 110, 112 are securely engageable with the recess 134 to a second position that allows the blade 108 and the first and/or second blade guard(s) 110, 112 to be released from the recess 134. In some other example embodiments, the release button is slidable in a perpendicular direction relative to the recess 134, the blade housing 106, and/or handle 102. A biasing mechanism or spring may be utilized to urge the engagement mechanism into the initial position, such that sliding the engagement mechanism into the second position puts tension on the engagement mechanism so as to urge the engagement mechanism back into the initial position once sliding pressure is removed. The engagement mechanism may also be any other type of mechanism that is arranged to engage and release the blade 108 and the first and/or second blade guard(s) 110, 112.


Turning now to FIGS. 4A-4E, the blade 108 and first and second blade guards 110, 112 are illustrated separate from the blade housing 106. The blade 108 and first and second blade guard(s) 110, 112 may be manufactured as a unit such that if they are removable from the blade housing 106, the blade 108 and first and second blade guards 110, 112 are removed as a unit. Otherwise, one or more components of the blade 108 and first and second blade guards 110, 112 may be separately removable and replaceable relative to the handle 102.


In some example embodiments, the blade 108 has a length defined between a first end and a second end thereof and comprises a cutting edge formed at an intersection between lateral sides of the blade 108. An edge of the blade 108 opposite the cutting edge 136 and formed at an intersection between the lateral sides of the blade 108 may be the top edge of the blade 108 that is engageable with the recess 134 of the blade housing 106. The blade 108 may be any type of blade sharpened on one edge (i.e., the cutting edge). The blade 108 may comprise stainless steel, high carbon steel, or another similar material.


The first blade guard 110 may have a length defined between a first end and a second end thereof and forming the arcuate shape along its length. The first blade guard 110 may comprise a planar body portion 138 extending between the first end and the second end of the first blade guard 110 and forming the arcuate shape along its length, and guard teeth 140 extending from and coplanar with the planar body portion 138 in a planar configuration and orientable transversely to the planar body portion 138 of the first blade guard 110 in a non-coplanar configuration. The planar configuration of the first blade guard 110 is illustrated in FIG. 4A, while the non-coplanar configuration of the first blade guard 110 is illustrated in FIGS. 4B-4E. As shown in FIG. 4B, the planar body portion 138 of the first blade guard 110 may be arranged adjacent to one of the lateral sides of the blade 108 and the guard teeth 140 of the first blade guard 140 may be folded over the cutting edge 136 of the blade 108 in the non-coplanar configuration to partially cover the cutting edge 136 of the blade 108. The first blade guard 110 may comprise stainless steel, high carbon steel, or another similar material, and may be the same as or a different material than the blade 108.


Likewise, the second blade guard 112 may have a length defined between a first end and a second end thereof and forming the arcuate shape along its length. The second blade guard 112 may comprise a planar body portion 142 extending between a first end and the second end of the second blade guard 112 and forming the arcuate shape along its length, and guard teeth 144 extending from and coplanar with the planar body portion 142 in a planar configuration and orientable transversely to the planar body portion 142 of the second blade guard 112 in a non-coplanar configuration. The planar configuration of the second blade guard 112 is illustrated in FIG. 4A, while the non-coplanar configuration of the second blade guard 112 is illustrated in FIGS. 4B-4E. As shown in FIG. 4B, the planar body portion 142 of the second blade guard 112 may be arranged adjacent to the other one of the lateral sides of the blade 108 and the guard teeth 144 of the second blade guard 110 may be folded over the cutting edge 136 of the blade 108 in the non-coplanar configuration to further partially cover the cutting edge 136 of the blade 108. The second blade guard 112 may comprise stainless steel, high carbon steel, or another similar material, and may be the same as or a different material than the blade 108.


In the non-coplanar configurations and as shown in FIGS. 4B and 4D-4E, the guard teeth 140 of the first blade guard 110 and the guard teeth 144 of the second blade guard 112 may oppose one another and may be alternately folded over the cutting edge 136 of the blade 108. As shown in FIG. 4C, for example, when folded, the guard teeth 140, 144 have a U-shaped profile. This enables the blade 108 to be sandwiched between the first blade guard 110 and the second blade guard 112 to limit the cutting depth of the blade 108 during use. The guard teeth 140, 144 on the first blade guard 110 and the second blade guard 112 may be substantially uniform in width or may be tapered. A width of the guard teeth 140, 144 may be smaller than a width between each guard tooth 140, 144, which is desirable so as to not fully cover the cutting edge 136 in the non-coplanar configuration.


Accordingly, and as shown in FIGS. 4A-4E, the blade 108, first blade guard 110, and/or second blade guard 112 (i.e., a portion of the curved blade assembly 104) may form an arcuate shape along each of their respective lengths. The arcuate shape formed by the blade 108, first blade guard 110, and/or second blade guard 112 may match the arcuate shape formed by the blade housing 106 or may have a different curvature and/or shape. The recess 134 may similarly be formed with the arcuate shape so as to complimentarily receive the blade 108, first blade guard 110, and/or second blade guard 112 therein.


One or more openings 146 may be defined along the top edge of the blade 108, first blade guard 110, and/or second blade guard 112 such that when the first blade guard 110 and second blade guard 112 are arranged adjacent to the lateral sides of the blade 108, the openings align. The openings 146 may cooperate with the recess 134 in order to engage the blade 108, first blade guard 110, and/or second blade guard 112 with the recess 134. For example, where the blade 108, first blade guard 110, and/or second blade guard 112 are overmolded with the blade housing 106, the material forming the blade housing 106 may flow into and around the openings 146 so as to integrally form the curved blade assembly 104. In another example, the recess 134 may define one or more protrusions (not shown) that may act as the engagement mechanism to releasably engage the openings 146 defined along the top edge of the blade 108, first blade guard 110, and/or second blade guard 112. Actuation of the engagement mechanism may result in the protrusions engaging or disengaging the openings 146.



FIGS. 4B-4E further illustrate tabs 148a-d and grooves 150a-d arranged along an edge of the planar body portion 138, 142 of the first blade guard 110 and the second blade guard 112. Grooves 152a-d are correspondingly formed on the top edge of the blade 108.
