Definitions

  • the present invention is directed to razor heads and, more particularly, to razor heads comprising a foam skin-engaging material.
  • Previously disclosed shaving systems typically utilize relatively rigid materials, such as polypropylene, polystyrene or ABS, for certain skin-engaging elements which contact a person's skin during shaving.
  • relatively rigid materials such as polypropylene, polystyrene or ABS
  • the guard and cap control the angle at which the skin meets the cutting edge of the blade.
  • EP-A-0 276 066 discloses a flexible razor in which one or more blades are supported in a flexible, foam support that additionally functions as a handle.
  • EP-A-0 276 066 addresses the problems of providing a razor that conforms to skin contours; and of providing a razor handle that is easy to grip when wet or slippery.
  • the disclosure does not address the problem of improving the sensation of a razor on facial skin, and more specifically of how to improve the efficacy and positioning of a razor blade relative to skin and hairs.
  • US-A-4,872,263 discloses a lubricating device for a razor cartridge, the device including a foam member having a lubricating medium impregnated therein.

As illustrated in FIG. 1, it is most preferable that element 60 extends across substantially the entire width of the razor head.
  • the term “razor head” is meant to include both the operative section of disposable razors as well as disposable cartridges designed for attachment to a separate razor.
  • guard 40 is generally L-shaped, comprising a vertical leg 42 having a vertical surface 43 and a substantially horizontal leg 44 having a generally. horizontal surface 45.
  • guard 40 is fabricated from a rigid material such as the type generally used in fabricating razor heads, e.g., polypropylene.
  • guard 40 is preferably reduced in size and cross-section to a minimum required to suitably support element 60 thereon.
  • Element 60 preferably comprises a skin-engaging resilient foam material 62 and a pressure sensitive adhesive 68.
  • Resilient foam material 62 of this illustrated embodiment is rectangular in cross-section having an attachment surface 63 to which is attached a pressure sensitive adhesive 68.
  • Outer surfaces 64 and 65 of resilient foam material 62 provide a skin-engaging surface as further described below.

  • emulsifiers in some shaving preparations can attack the adhesive layer causing it to swell and become gel-like which can dramatically reduce the adhesive's mechanical strength.
  • adhesive 68 is able to withstand a shear stress of about 10 kPa to about 100 kPa.
  • Suitable pressure sensitive adhesives are manufactured and available from Lohmann GmbH and Co. of Neuwied, Germany, in particular, acrylic pressure sensitive adhesives, DUPLOTAC 160 and DUPLOCOLL 3701.
  • such suitable pressure sensitive adhesives allow adhesive 68 to be applied as a layer comprising a thickness of about 0.01 mm to about 0.2 mm, preferably about 0.05 mm to 0.1 mm thick.
  • resilient foam material 62 is illustrated in a configuration which could result under normal shaving forces.
  • the deformation of the resilient foam material is advantageously designed to provide a skin-engaging surface 67 and to slightly stretch the skin due to resilient foam material 62 having a higher coefficient of friction as compared to conventional rigid materials.
  • skin-engaging surface 67 reduces the deformation typically experienced by the beard hairs from contact with a guard member comprising a rigid material. After contact with the skin, resilient foam material 62 returns substantially to its original configuration as shown in FIG. 2.
  • the illustrated shaving cartridge is also provided on its lower side with suitable connecting members 70 for attachment to a razor.
  • the materials used for forming the various elements of the razor head may include a wide variety of materials. For example, it is known in the art to use thermoplastics which are particularly suited for injection molding and which have excellent durability and shelf life in the environments typically encountered during shaving, shipping and storing.
  • a plurality of fencing elements 80 prevent a plurality of discrete, spaced portions of cutting edges 21 and 31 of blades 20 and 30, respectively, from contacting the skin surface being shaved. It is also within the scope of the embodiment to utilize a skin-engaging element with shaving systems which do not have fencing elements.

  • Attached to guard 140 is a skin-engaging element 160.
  • skin-engaging element 160 of FIGS. 4 and 5 preferably extends across substantially the entire width of the razor head, however, the foam skin-engaging elements of the present invention can also be segmented or can extend across less than a major portion of the razor head.
  • Guard 140 is generally configured as an L-shaped support comprising a vertical leg 142 having a vertical surface 143 and a generally horizontal leg 144 having a generally horizontal surface 145.
  • the surface 145 is angled slightly so as to be about parallel to a surface tangent to the top of guard 140 and cap 110 which is represented in FIG. 4 as line 190.
  • skin-engaging element 160 comprises a resilient foam material 162, a first adhesive 164, a stiffener 166, and a second adhesive 168.
  • resilient foam material 162 is rectangular in cross-section having an upper skin-engaging surface 161 and a lower attachment surface 163.
  • resilient foam material 162 comprises an open cell foam.

  • element 160 is generally rectangular in cross-section, under typical shaving forces, as shown in Fig. 5, element 160 could be compressed to have a rhomboid configuration. Specifically, under typical shaving forces, attachment surface 163 will remain secured to surface 145 of leg 144 of guard 140 while skin-engaging surface 161 could move downwardly and toward vertical surface 143 of guard 140. After removal of contact with the skin, resilient foam material 162 returns substantially to its original configuration as shown in FIG. 4.
  • resilient foam material 162 can first be laminated to stiffener 166 by adhesive layer 164.
  • stiffener 166 can be fabricated from a PET foil. From the description, those skilled in the art will appreciate that other forms of stiffeners can also be utilized without departing from the scope of the present invention.
  • the resilient foam material 162 and stiffener 166 laminate is provided with an adhesive layer 168 for attachment or mounting to surface 145 of guard 140 (FIGS. 4 and 5).

  • a large laminated planar sheet can be formed comprising a layer of resilient foam material, an adhesive layer, a stiffener, and a self-adhesive layer which is disposed on the outer surface of the stiffener.
  • a planar sheet comprising a resilient foam material and a backing film can be slit and coiled. The coils can then be cut so that a "ladder-shaped" portion can be removed to provide coils having a plurality of discrete portions or individual labels on a continuous backing film.
  • this process has a relatively low yield due to the discarded "ladder-shaped" portion.
  • the individual labels may be generally rectangular in cross-section, as described in FIG. 4-6, but may also be parallelogram or trapezoid-shaped as explained below with a slight decrease in yield.
  • FIGS. 7-10 illustrate two alternative embodiments of skin-engaging elements and guard of the present invention.

  • FIG. 9 shows a guard 340 having a surface 345 which attaches to a skin-engaging element 360.
  • skin-engaging element 360 has a trapezoid-shaped cross-sectional configuration. It is appreciated that these configurations, compared to the configuration shown in FIGS. 4-6, require less applied force when compressed under typical shaving forces thereby reducing the reaction force from the skin's surface and providing less discomfort.
  • the configurations shown in FIGS. 7-10 provide a larger skin-engaging surface thereby increasing the friction and skin sensation.
  • FIG. 11 is a cross-sectional view of an alternative foam skin-engaging element 460 comprising a rear surface 462, in lower surface 464 and a curved skin-engaging surface 466. Either or both of rear surface 462 and lower surface 464 can be attached to a support surface of a razor head.

  • FIG. 14 illustrates a still further configuration of a foam skin-engaging element 660 wherein portions 662 are separated by slits.
  • the illustrated slits actually create a space between separate portions 662, it is also within the scope of the present invention to utilize foam having slits which, after cutting, do not leave visible spaces between neighboring sections of the foam skin-engaging element due to the natural resiliency of the foam. Nonetheless, such slits will enhance relative movement between such portions during shaving. While the illustrated slits extend only a minor portion of the extent of the foam skin-engaging element, it is also within the scop of the present invention to make such slits either much shallower or deeper into the skin-engaging element 660.
