Definitions

  • This invention relates to a razor head. More particularly the invention relates to a twin bladed shaving system in particular one having means for cleaning shaving debris from the top of each blade in the system.
  • US-A-2,780,682 discloses a disposable razor having a fingered cap with angled slots positioned between the fingers which aid in the provision of a rinsable surface for the cap. This surface, which is preferably at an angle, enables the removal of debris from the space between the fingers by rinsing the razor head.
  • This slanted recessed area does help in the removal of debris but does nothing to remove the debris from between the blades in a twin bladed shaving system such as that disclosed in US-A-3,786,563.
  • This shaving system which is becoming increasingly popular as both a disposable razor and also in a shaving cartridge, features two relatively narrow blades separated by a spacer which maintains the spatial relationship between the blades.
  • the blades are mounted with the shaving edges parallel to each other with the top most blade being recessed from the bottom most blade.
  • a seat which supports the bottom most blade has a guard bar extending outwardly from the seat beyond the edge of the bottom most blade.
  • a cap is provided to help maintain the orientation of the shaving components and also protect the top surface.
  • staking means which can be provided by projections downward from the cap through mating slots in the blades and spacer locking into suitable openings in the seat, or the process can be reversed using staking means upstanding on the seat.
  • US-A-4,205,437 and US-A-4,344,227 disclose a combination spacer/ejector. Basically, these patents disclose the concept of a twin bladed razor, such as that disclosed in US-A-3,786,563, with an open back and a spacer which is anchored in place by staking means extending downward from the cap through the upper blade assembly.
  • the spacer is an achor for a biased unitary ejector bar which extends parallel to the blade edges and is reciprocally movable to push shaving debris out from the top surface of the bottom blade as it is activated.
  • the ejector bar which is biased against the anchoring portion of the spacer is activated in a forward direction against the bias by a thumb activator which extends through the open back portion of the razor.
  • the ejector bar when activated, actually extends beyond at least the edge of the upper blade and preferably beyond the edge of the lower blade, forcing out the debris which is collected between the blades.
  • the combination ejector spacer is extremely efficient in the removal of debris collected between the blades
  • the conventional cap with an edge which is parallel to the blade edges tends, to collect debris which can get lodged in the junction between the top of the blade and the cap.
  • the distance between cap edge and upper blade edge is minimal and the possibility of the debris inhibiting upper blade performance is increased.
  • a dual razor blade razor head having first and second cleaning blade means for cleaning the blades.
  • the first cleaning means can clean an upper blade, whilst the second blade cleaning means can clean a lower blade.
  • a razor head characterised by a blade seat, a lower blade disposed on said seat, an upper blade disposed above said lower blade, said upper and lower blades preferably having spaced substantially parallel shaving edges, preferably a guard bar extending from the seat below and beyond the shaving edge of the bottom blade, spacing means for maintaining the upper and lower blades in spaced parallel relationship, a cap disposed over the upper blade, and first and second blade cleaning means disposed over the upper and lower blades to remove shaving debris.
  • the first blade cleaning means comprises a series of fingers extending toward the blade edge, said fingers being separated by recesses with inclined back walls sloping toward said blade edge, said fingers being provided on the cap.
  • the fingers may form part of the cap.
  • the angle between the plane of the blade and the wall of the recess is greater than 90°, preferably about 110°.
  • the recess forms a web interrupted by said fingers.
  • the second blade cleaning means comprises ejector means, said ejector preferably having a unitary transversely extending ejector element extending parallel to and substantially along the length of said shaving edges, said element being biased and reciprocally movable parallel to the blades.
  • the ejector means is activated by operating means extending beyond a rear portion of the razor head.
  • the spacer means is combined with the ejector means as unitary assembly.
  • the razor head may be in the form of a cartridge attachable to a handle, or may be part of a disposable razor in which the handle is integral with the razor head.
  • a razor head includes a cap 12 having a raised central area 17 with fingers 11 extending outwardly therefrom. Slots 15 taper outward from the raised area 17 between the fingers 11. Sides 19 of the cap 12 are designed to rest upon longitudinal edges of a support surface 41 of a seat 10.
  • the razor head further includes upper and lower blades 14 and 16, and a spacer/ejector 18.
  • Staking means in the form of four separate stakes 13 extends downward through two elongate holes 23 provided in the top blade 14.
  • the stakes 13 extend also through holes 33 providing anchor sites in the spacer/ejector 18, through matching elongate holes 43 in the lower blade 16, and into seat holes 53 provided in the seat 10.
  • the stakes 13 have an extended bottom portion which is positioned below the planar blade support portion 41 of the seat 10.
  • a guard bar 40 extends outward from the seat 10 and is attached thereto by ribs 43.
  • the spacer/ejector 18 has a bar 32 which extends parallel to, and has approximately the same length as, the blade shaving edge on blades 14 and 16.
  • the bar 32 is connected to operating means in the form of a pusher member 30 by a perpendicular connector 38.
  • the perpendicular connector 38 has a beam spring 36 depending from either side and attached to an anchor portion 37 positioned around each hole 33.
  • the slots 15 have an angle measured from the plane formed by the blade 14 and angled portion of the recess 15 greater than 90° and preferably about 110°.
  • a web may be disposed such that is extends with the recessed area to a secondary edge of reduced thickness extending only slightly inward from the cap. The addition of the web tends to aid in the maintaining of the cap in a rigid position.
  • the web may comprise a substantially flat piece of material disposed at the bottom of each recess and extending between the fingers.
