Definitions

  • the present invention relates generally to shaving implements, and, more particularly, to a razor cartridge for use with a shaving implement.
  • Modern shaving implements can include a plurality of blades disposed within a razor cartridge.
  • the razor cartridge is, in turn, mounted on a handle during use.
  • Some safety razors have a disposable razor cartridge that is selectively detachable to a reusable handle, while others have a handle and a razor cartridge that are manufactured as a single, disposable unit.
  • the motorized eccentric spinning weight can provide numerous advantages to the shaving implement, such as, but not limited to, providing a closer shave.
  • the razor cartridge typically includes one or more blades, a guard forward of the blades, and a cap aft of the blades.
  • the guard is operable to stretch the surface being shaved prior to encountering the one or more blades, and the blades are operable to shave the unwanted hair from a surface
  • the cap typically includes a lubricating strip that has post-shave benefits.
  • guards typically function only to pre-stretch the surface being shaved, but provide few comfort benefits. It is known, however, to place a lubricating (or comfort) strip forward of the one or more blades and aft of a skin-stretching member in order to lubricate, medicate, or otherwise treat the skin prior to shaving.
  • a lubricating (or comfort) strip forward of the one or more blades and aft of a skin-stretching member in order to lubricate, medicate, or otherwise treat the skin prior to shaving.
  • the skin-stretching member includes numerous protrusions. The comfort strip and numerous protrusions can make the razor cartridge difficult to use in certain instances (e.g., in tight locations).
  • the distance between the blades ⁇ i.e., the "inter-blade span", which is measured in the shaving direction across the razor cartridge along a straight line between the sharpened cutting edges of neighboring blades
  • the inter-blade span increases shaving comfort because a smaller skin bulge enters into the gap between adjacent blades during normal shaving.
  • reducing the inter-blade span between blades typically has a negative impact on the rinsability of the razor cartridge.
  • the smaller the span between the blades the more debris that tends to collect therein.
  • Blade exposure is an important factor that relates directly to the comfort and safety of a razor cartridge.
  • Blade exposure for the purposes of the present application, is defined to be the perpendicular distance or height (positive or negative) of the cutting edge of the blade being measured with respect to a plane tangential to the outermost surface of the skin-engaging feature immediately in front of, and immediately aft of the edge. Therefore, there is a need in the art to provide a razor cartridge for use with an associated handle that decreases the inter-blade span of the blades disposed in the razor cartridge in order to increase comfort, without limiting rinsability. In addition, there is also a need to provide a razor cartridge having a guard that provides comfort benefits without sacrificing maneuverability of the razor. It is, therefore, an object of the present invention to overcome the known shortcomings of the prior art.
  • a razor cartridge includes at least three (3) razor blades, a guard, a cap, and a rinse-through gap.
  • the guard is located forward of the blades and includes a skin- stretching member and a lubricating strip.
  • the skin- stretching member includes a single, continuous protrusion that extends across at least a portion of the guard.
  • the blades are substantially parallel to one another and include a first blade adjacent the guard, a last blade adjacent the cap, and at least one middle blade between the first and last blades.
  • the first blade has an exposure of zero or less.
  • the at least one middle blade between the first blade and the last blade have exposure(s) of approximately zero, and the last blade has an exposure greater than zero.
  • the first blade is approximately 1.3mm aft of the guard.
  • the remaining blades (i.e., the last blade and the at least one middle blade positioned between the first and last blades) have inter-blade spans of approximately 1.0mm, or less.
  • the cap includes at least one lubricating strip. The rinse-through gap allows water to pass between the blades, rinsing any debris from there between.
  • the razor cartridge is mounted on a handle having a vibration mechanism therein.
  • the rinse-through gap is substantially parallel to the at least three (3) blades.
  • the razor cartridge includes four (4) blades.
  • One advantage of the present invention is that the blades have reduced inter- blade spans, and therefore allow a smaller skin bulge of the surface being shaved to enter into the gap between adjacent blades.
  • the smaller skin bulge reduces the friction between the surface being shaved and the blades, resulting in a more comfortable shave.
  • the razor cartridge is selectively attached to a handle that vibrates.
  • the vibrating handle also tends to loosen debris (when rinsing out the razor cartridge), such as hair follicles, that may become lodged between the blades during shaving. Therefore, despite the reduced inter-blade spans, the razor cartridge is unlikely to be adversely affected by a build-up of debris between the blades.
  • a further advantage of the present invention is the combination of the lubricating strip and the skin-stretching member on the guard bar.
  • the lubricating strip treats the skin prior to being shaved, providing for a more comfortable shave.
  • the skin-stretching member of the guard bar includes a single protrusion that extends across the guard. Therefore, the guard pre-stretches and lubricates the skin without being overly large, and difficult to maneuver in tight areas.

  • the guard 12 is located forward of the blades 14 and includes a skin-stretching member 18 and a lubricating (or comfort) strip 20.
  • the skin-stretching member 18 includes a single, continuous protrusion 22 that extends across at least a portion of the guard 12.
  • the blades 14 are substantially parallel to one another and include a first blade 24 adjacent the guard 12, a last blade 26 adjacent the cap 16, and at least one middle blade 28 between the first and last blades 24, 26.

  • the cap 16 includes at least one comfort strip 20.
  • a rinse-through gap 30 extends between the guard 12 and cap 16 and between the blades 14 (FIGS. 5 and 5A). Therefore, when rinsing out the razor cartridge 10 of the present invention, the rinse-through gap 30 allows water to pass between the blades 14, rinsing any debris from there between.
  • the razor cartridge 10 is coupled to a handle 32.
  • the razor cartridge 10 can be coupled in a manner such that the razor cartridge 10 is selectively detachable from the handle 32, or, in other instances, the razor cartridge 10 may not be intended to be detached from the handle 32 during normal use.
  • the razor cartridge 10 may be fixedly or pivotally attached to the handle 32.
  • the handle 32 may further include a biasing member 34 that is operable to urge the razor cartridge 10 toward a rest position (see FIG. 2).
  • the biasing member 34 is a spring-loaded plunger 36; however, any type of biasing member 34 known to those in the art may be utilized.
  • the biasing member 34 is movable between an extended position (when the razor cartridge 10 is in a rest position), and a retracted position (when the razor cartridge 10 is pivoted relative /to handle 32 when, for example, forces that occur during normal shaving are placed on the razor cartridge 10). Once the forces are no longer acting on the razor cartridge 10, the biasing member 34 returns the razor cartridge 10 to the rest position.
  • the razor handle 32 includes a vibration mechanism 38 capable of vibrating the razor cartridge 10, as shown in FIG. 2.
  • the vibration mechanism 38 is preferably a motorized spinning eccentric weight 40.
  • a spinning eccentric weight causes vibrations in a plane substantially perpendicular to the axis 42 about which the eccentric weight spins 40 (See FIG. 2, which indicates the axis of rotation).
  • the vibration mechanism 38 may be positioned in the handle 32 in any suitable manner; however, it is preferable that the vibration mechanism 38 be completely encased between a first and second injection molded portions 44, 46 (e.g., the vibration mechanism 38 is secured to a first molded portion 44, then a second molded portion 46 is molded onto the first molded portion 44, encasing the vibration mechanism between the first and second molded portions 44, 46).
  • the vibration mechanism 38 is oriented in (or on) the handle 32 such that the axis 42 about which the eccentric weight 40 spins is substantially perpendicular to the blade plane of at least one blade 14 (see e.g., FIG. 2).
  • the vibration mechanism 38 when the vibration mechanism 38 is turned on, the vibrations cause at least one of the blades 14 to vibrate in the blade plane.
  • the action of a blade 14 vibrating in the blade plane results in the blade 14 making a "chopping" motion.
  • the chopping motion effectively reduces the cut force of the blade 14. Reducing the cut force generally provides a more comfortable shave.
  • the handle typically includes a switch 48 that is operable to activate and deactive the vibration mechanism 38.
  • the switch 48 and the vibration mechanism 38 are typically connected in a circuit that includes a power source 50, such as a battery 52.
  • the battery 52 may be housed in a cavity 54 in the handle (see e.g., FIG. 2) that is selectively accessible via a removable cap 56.
  • the battery 52 can also be encased within the outer surface 58 of the handle 32.
  • the cap 16 is located aft of the blades 14 and includes a lubricating strip 20.
  • the lubricating strip 20, also often referred to as a comfort strip, can include any shaving aid known in the art.
  • Shaving aids include any material that lubricates, medicates, or otherwise advantageously treats the surface being shaving before, during, or after the shaving process.
  • the razor cartridge 10 of the present invention includes at least three (3) blades 14, and preferably four (4) blades 14.
  • Each razor blade 14 includes a sharpened cutting edge 60, and, as discussed above, defines a blade plane, as shown in FIG. 2.
  • the blades 14 are mounted in the razor cartridge 10 in a manner such that the blade plane of each blade 14 is parallel to the blade planes of each of the other blades 14.
  • the blades 14 of the present invention are positioned in the razor cartridge 10 such that the span ("S") between the first blade 24 and guard 12 is approximately 1.3mm, and the inter-blade spans ("Sl", “S2”, etc.) between the remaining blades 14 (as shown in FIG. 5) is approximately 1.0mm.
  • the span ("S") between the first blade 24 and the guard 12 is determined by measuring the length of a straight line drawn tangential to the guard 12 and the cutting edge 60 of the first blade 24 aft of the guard 12).
  • the first blade 24, in some embodiments has an exposure of zero or less (preferably, between zero and approximately -0.03mm).
  • the last blade 26 has an exposure that is positive, and preferably between zero and 0.03mm.
  • Each of the blades 14 between the first and last blades 24, 26 preferably has an exposure of approximately zero.
  • the blades 14 may be manufactured from any suitable material; however, stainless steel has proven to have particular utility. Typically, the blades 14 are flexible, and therefore, must be at least partially supported when positioned within the razor cartridge 10.
  • the blades 14 of the present invention may be supported in any suitable manner. For example, in some embodiments, such as the one shown in FIG. 5, the blades 14 may be supported at various points along the blade 14 by cartridge material 62. Alternatively, in some embodiments, the blades 14 may include a dedicated blade support 64 (e.g., a bent piece of metal) that is affixed (e.g., welded at various locations) to the blade 14 before insertion into the razor cartridge 10.
