Definitions

  • This invention relates generally to the application of sunless tanning formulations to the face and body of an individual and, more particularly, to a brush device especially designed for such applications.
  • Sunless tanning formulations generally fall into two categories, namely, sunless tanners that actually darken the skin and then fade as dead skin cells slough off in the normal course (usually within 3-7 days), and bronzers that wash off like regular makeup. Most sunless tanners contain dihydroxyacetone, a sugar that interacts with proteins in the epidermis, the outermost layer of the skin, to produce a darker skin color. Sunless tanners come in various forms. A gel is particularly advantageous form for sunless tanning formulations since gels generally dry faster and are easier to apply than other forms, such as spray tanners which are more difficult to use, and lotions which sometimes leave a sticky feel. Bronzers darken the skin on a temporary basis. Once applied to the body and face of an individual, a tan is created that can be washed off with soap and water. Bronzers also come in several forms, including powders, liquids and gels.

Description

    BACKGROUND OF THE INVENTION
  • This invention relates generally to the application of sunless tanning formulations to the face and body of an individual and, more particularly, to a brush device especially designed for such applications.
  • The popularity of sunless tanning has risen since the 1960s after exposure to the sun and other tanning methods, such as tanning beds, were linked to the incidence of skin cancer. Sunless tanning and bronzing formulations are safer and faster than, and can achieve a tan at least comparable to that obtained by, exposure of the face and body of an individual to the sun.
  • Sunless tanning formulations generally fall into two categories, namely, sunless tanners that actually darken the skin and then fade as dead skin cells slough off in the normal course (usually within 3-7 days), and bronzers that wash off like regular makeup. Most sunless tanners contain dihydroxyacetone, a sugar that interacts with proteins in the epidermis, the outermost layer of the skin, to produce a darker skin color. Sunless tanners come in various forms. A gel is particularly advantageous form for sunless tanning formulations since gels generally dry faster and are easier to apply than other forms, such as spray tanners which are more difficult to use, and lotions which sometimes leave a sticky feel. Bronzers darken the skin on a temporary basis. Once applied to the body and face of an individual, a tan is created that can be washed off with soap and water. Bronzers also come in several forms, including powders, liquids and gels.
  • With the development of sun tanning formulations in liquid, powder and gel form, issues have arisen with the use of conventional devices for applying the formulations to the skin. Conventional techniques, such as conventional brushes and mitts, generally require a long time for application of the formulation to large areas of the body. Certain areas of the body, such as areas of the back and legs, often cannot be easily reached, if at all. Leverage to apply appropriate pressure of brushes often cannot be obtained using conventional mitts and/or brushes. For these reasons, the tan produced by these techniques and other conventional methods, are often streaked and/or uneven.
  • SUMMARY OF THE INVENTION
  • Accordingly, it is an object of the present invention to provide a new and improved device for applying sunless tanning formulations to the body and face of an individual.
  • Another object of the present invention is to provide a new and improved brush device for applying sunless tanning formulations to the body and face of an individual.
  • Still another object of the present invention is to provide an improved brush device for applying sunless tanning formulations to the body and face of an individual that is faster than conventional techniques.
  • A further object of the present invention is to provide a new and improved brush device for applying sunless tanning formulations to the body and face of an individual which results in a uniform, streak-free tan.
  • A still further object of the present invention is to provide a brush device satisfying all of the above objects and which is convertible to a closed configuration after use in which the brush of the device is protected and which is compact.
  • It has been found that a brush device having a certain configuration and certain specific dimensions in accordance with the invention satisfies all of the above-stated objects. Briefly, in accordance with the present invention, these and other objects are attained by providing a brush device comprising an elongate cylindrical handle structure having a length in the range of between about 4¼ inches and 5¼ inches and a diameter in the range of between 1¼ inches and 2 inches, and a brush formed by a plurality of bristles that extend from an end of the handle structure. The brush has circular transverse cross-sections of varying size, the largest circular transverse cross-section having a diameter of between 2¼ inches and 2¾ inches. A brush device having such a construction can be used to apply a sunless tanning formulation in gel, liquid or powder form more quickly than other conventional techniques and at the same time provide a streak-free and uniform tan. The construction also allows an individual to reach all areas of his or her body and provides the user with good leverage during the application of the formulation to hard-to-reach areas.
  • According to another aspect of the invention, the handle structure is configured to conveniently house and protect the brush after use in a compact profile. In particular, the handle structure includes an outer cylindrical case, an inner cylindrical brush holder situated within the outer case, and an intermediate cylindrical case situated between the outer case and the inner brush holder which is slidable between a retracted position in which the brush is exposed, and an extended position in which the brush is covered by the intermediate cylindrical case. A cylindrical cover is connectable to the intermediate cylindrical case while in its extended position, whereupon the intermediate cylindrical case can be moved to its retracted position, whereupon the brush becomes covered within the cylindrical cover providing a compact package while protecting the brush.
  • DESCRIPTION OF THE DRAWINGS

  • FIG. 1 is a perspective view of a brush device in accordance with the invention;
  • FIG. 2A is a front elevation of the brush and an upper portion of the intermediate cylindrical case of the brush device of FIG. 1;

  • FIG. 3 is a longitudinal section view of the brush device of FIG. 1;
  • FIG. 4 is a longitudinal section view of the brush device of FIG. 1 in a first stage of being closed after use;
  • FIG. 5 is a longitudinal section view of the brush device of FIG. 1 including a cover in a second stage of being closed after use; and
  • FIG. 6 is a longitudinal section view of the brush device of FIG. 1 in its closed configuration.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring now to the drawings wherein like reference characters designate identical or corresponding parts throughout the several views, and more particularly to FIGS. 1 and 2, a brush device 10 in accordance with the invention is illustrated in an open configuration ready for use. The brush device 10 includes an elongate cylindrical handle structure, generally designated 12, having a longitudinal axis 11 (FIG. 2A) and a brush 14 formed of a plurality of bristles 16. The elongate cylindrical handle structure 12 has a first closed longitudinal end 18 and a second open longitudinal end 20.
  • The length 22 of the handle structure is in the range of between about 4¼ inches and 5¼ inches, most preferably about 4¾ inches. The diameter 24 of the cylindrical handle structure is in the range of between about 1¼ inches and 2 inches, preferably about 1½ inches.
  • Referring to FIG. 2 brush 14 extends from the second open and 20 of the handle structure 12 has a lower part 14 a having a frusto-conical shape and an upper part 14 b having a substantially spherical section shape. Cross-sections of brush 14 have circular shapes in respective planes transverse to the longitudinal axis 11 of the handle structure 12. The transverse cross-section of brush 14 at the second open end 20 of the handle structure has a diameter 26 in the range of between about 1¼ and 2 inches, preferably about 1½ inches. The transverse cross-section of brush 14 at its widest part, i.e., at the major base of the frusto-conical part 14 b (FIG. 2B) has a diameter 28 in the range of between about 2¼ inches and 2¾ inches, preferably about 2½ inches. The height 30 of brush 14 measured from the open end 20 of the handle structure 12, is in the range of between about 1⅝ inches and 2⅛ inches, preferably about 1⅞ inches. The length 32 of the frusto-conical edge of the lower frusto-conical part 14 b of brush 14, measured from the open end 20 of the handle structure 12, the range of between about 1¼ inches and 1¾ inches, preferably about 1½ inches.
  • It has been found that a brush device having a combination of certain ones, or all, of the characteristics described above, in addition to reducing the time required to apply sunless tanning formulations in liquid, gel and/or powder form to the face and body, eliminates or at least reduces streaking and promotes uniformity of application in hard-to-reach areas as a result of the increased leverage provided by the brush device. Larger or smaller brushes connected to narrower, wider, longer and/or shorter handle structures result in increased streaking due to insufficient or excess pressure of the brush on the skin and insufficient leverage.
  • Because of the large size of the brush of a brush device in accordance with the invention, it is desirable to provide a construction which will protect the bristles from damage after the brush is used. At the same time, it is desirable to provide a compact packaging for the brush device, not only in view of the large size of the brush, but also in view of the large size of the handle structure. To these ends, referring to FIGS. 3-6, the handle structure of a brush device 10 in accordance with the invention includes a plurality of elements formed of appropriate material, such as aluminum, or plastic, which enables the brush device to be converted to a closed configuration having approximately the same overall height as the brush device in its open configuration with the brush gathered and housed in a protective cap.
  • The handle structure 12 includes an outer cylindrical case 34 having a closed end constituting the first closed end 18 of the handle structure 12 and an open end 36, an inner cylindrical brush holder 38 situated coaxially within the outer cylindrical case 34 having a closed end 40 fixed, such as by adhesive, to the inner surface of the closed end 18 of the outer cylindrical case 34 so as to fix the inner cylindrical brush holder 38 within the outer cylindrical case 34, and an open-ended intermediate cylindrical case 42 situated coaxially and slidably between the outer cylindrical case 34 and the inner cylindrical brush holder 38. As described below, one of the open ends of the intermediate cylindrical case is situated outside of the outer cylindrical case and constitutes the second open end 20 of handle structure 12.
  • A circumferentially extending shoulder 44 projects outwardly from the intermediate cylindrical case 42 at a location close to but spaced from the open end 20 of the intermediate cylindrical case 42 such that when the intermediate cylindrical case 42 is moved as far as possible into the outer cylindrical case 34 (as seen in FIG. 3), the shoulder 44 engages the open end 36 of the outer cylindrical case 34 preventing further inward movement of the intermediate cylindrical case 42 into the outer cylindrical case 34. As noted above, in this position, the open end of the intermediate cylindrical case 42 proximate to shoulder 44 is situated outside of the outer cylindrical case 34 and constitutes the second open end 20 of the handle structure 12.
  • The ends of the bristles 16 of brush 14 are affixed by epoxy or the like in a brush-holding cup 46 which is fixed at the upper end of the inner cylindrical brush holder 38 within the outer cylindrical case 34. The bristles 16 extend through the open end 20 of the handle structure constituted by the open end of the intermediate cylindrical case 42 and have a length and configuration such as to form brush 14 with the configuration and dimensions described above.
  • The open end 20 of handle structure 12 constituted by the open end of the intermediate case 42 projects a distance 48 of about ¾ inch from the open end 36 of the outer case 34. The length 50 of the intermediate case 42 is about 3⅞ inches. The length 52 of the inner brush holder 38 is about 3¼ inches and the open end 39 of the brush holder 38 at which the brush-holding cup 46 is fixed is situated within the outer case 34 and spaced a distance 54 of about ¾ inch from the open end 36 of the outer case 34.
  • The handle structure 12 described above is constructed to conveniently house and protect the brush after use in a compact profile. Referring to FIG. 4 in conjunction with FIG. 3, in a first stage of closing the brush device 10 after it has been used to apply a tanning formulation, the intermediate cylindrical case 42 is slid outwardly from within the outer cylindrical case 34 until an inwardly extending circumferential shoulder 52 formed at the inner end of the intermediate cylindrical case 42 engages an outwardly extending circumferential shoulder 54 formed at the top end of the inner cylindrical brush holder 38. The engagement of shoulders 52, 54 limits the extent of sliding movement of the intermediate cylindrical case 42 out of the outer cylindrical case 34. The extent of movement of the intermediate cylindrical case 42 is sufficient such that the bristles 16 of brush 14 are gathered together by the intermediate case 42 as it moves outwardly and within the interior of the intermediate cylindrical case 42. The bottom edge of cover 56 abuts the shoulder 44 of the intermediate cylindrical case.
  • Referring to FIG. 5, in the next stage of closing the brush device 10, with the intermediate cylindrical case 42 in its outer position, a cylindrical cover 56 is connected to the open end 20 of the intermediate cylindrical case 42. Small protrusions are formed on the upper end of the intermediate case to provide a friction fit of the cover 56 onto the intermediate case 42. The bottom edge of cover 56 abuts the shoulder 44 of the intermediate cylindrical case.
  • Referring to FIG. 6, in the final stage of closing the brush device 10, the intermediate cylindrical case 42 is slid back into the outer cylindrical case 34 until the shoulder 44 engages the open end 36 of the outer cylindrical case 34 but not so long as to be cumbersome. The length 58 of the cylindrical cover 56 is sufficient to provide a space for receiving and housing the gathered brush 14 in its interior as the intermediate cylindrical case 42 slides into the outer cylindrical case 34. The length of the cylindrical cover is in the range of between about 3⅞ inches and 4⅛ inches, preferably about 4 inches. In this manner, the brush device is closed in a compact package having about the same length as the brush device in the open configuration with the bristles 16 of brush 14 being protected.
  • The outer cylindrical case 34, inner cylindrical brush holder 38 and intermediate cylindrical case 42 are thus configured such that the intermediate cylindrical case 42 is slidable between a first retracted position (FIG. 3) in which the open end 20 thereof is situated outside of the outer cylindrical case a first distance from the open end of the outer case and constitutes the second longitudinal end of the handle structure, and a second extended position (FIG. 4) in which the open end 20 thereof is situated outside of the outer cylindrical case a second distance from said open end of said outer case which is greater than the first distance. The brush 14 is housed within the intermediate case 42 when the intermediate case 42 is in said second extended position (FIG. 4). The cylindrical cover 56 has a first closed end and a second open end, the second open end being configured to be connected to the open end 20 of said intermediate cylindrical case 42 when the intermediate cylindrical case is in the second extended position (FIG. 5). The brush 14 becomes housed within the cylindrical cover 56 when the intermediate cylindrical case 42 is moved to the first retracted position (FIG. 6).
  • Obviously, numerous modifications and variations of the embodiment of the brush device are possible in the light of the above teachings. It is therefore to be understood that within the scope of the claims appended hereto, the invention may be practiced otherwise than as specifically disclosed herein.
