Abstract
A safety razor having one or more blades (14) seated between a cap (11) and guard (12), said guard cap and guard having a comb configuration in which a comb like moulding (18) of a mixture of polyethylene oxide and a structural polymer, such as polystyrene is positioned between the teeth (13) of the comb-like cap portion, the teeth (19) of the polyethylene oxide-containing moulding being narrower than the space between the teeth of the cap portion so that the blade unit can flex concavely.

polyethylene oxide co~ ining inserts in a flexible blade unit of the kind described.
A ~uL~enLly preferred . ~o~i -nt of the invention will now be described, by way of example, with reference to the i~-c ,-nying ~rawings, in which:
Figure 1 is a perspective exploded view of the razor, and Figure 2 is a similar view of the assembled razor.
The illustrated razor comprises a flexible blade unit 10 which comprises a moulded plastics housing 11 (made, for example, from poly~Ly.~r.e) which has a comb-like guard portion 12 and a comb-like cap portion 13 between which a combination of tandem single edged razor blades 14 with a sp~c~r 15 therebetween is.
., clamped. The blades 14 and spacer 15 are retained in the coLL~L position by ~LUL~clon~i (not shown) in the housing and ~luLL~sions (not shown) on the spacer 15 which ~S~gi~ge in slots 16 in the bl ~A~S . Slots are used so as to allow relative muv~ - L of the blades and . spAcer during flexing. The teeth-of the comb-like ,.. portions 12,and.13 are:inteLco~ DcLed by a web 17 which -, is sufficiently thin~for the blade unit 10 to be :~ ~flexible. . .:., - ' . ~. , . The blade unit further comprises a comb-like ; polyethylene oxide _i~n~i~in;nq l~ing 18,-the teeth 19 of which are posit;nn~ beLs~een the teeth of the cap ., .portion,13,r~,theiwidth of~the teeth l9~being less than .the space beLs~_e.. the teeth of the,cap portion (when the 30 .~blade unit-is ~nfl~y~ so that the.blade unit can flex CO~s~ aVely ~ ~ i - - 5 The:teeth.l9 of.-the polyethylene oxide-r.~-con~ ning mo~ ng 18~are int~Lco~ D~Led by a~web 20 ~ which is~adhesively,;se~.ad.to the back'of the~web 17.
; 3S ~ As can be seen-from.Figure''2,r~ in the as'sembled~f '' ,condition,'.-the teeth~lg of~the polyethylene oxide-', .,cont~ining moulding 18 are level-with the teeth 13 of 2o~2~32 ~~
the cap portion.
Figures 1 and 2 further illustrate a preferred -nn~r of ACS~ ~ling the blade unit, that is the polyethylene oxide-cont~;ning moulding 18 is not separated from the sprue 21 with which it is moulded until the l~ng 18 has been ho~Ae~ to the housing 11;
the sprue 21 is then cut away (see Figure 2).
The blade unit 10 is co~n~cted to a handle 22 by means of three posts 23,24 ~p~;ng integrally from the underside of the housing 11 which slidably engage in co~lC~G~ing slots 25,26 in the head of the handle.
The posts 23,24 extend perp~n~ic~ rly to the parallel planes of the h~a~es and are positioned directly underneath the blade edges, i.e. passing through a region bordered by the blade edges. The central post 24 is guided for rect;l;n~r sliding .~ -nt within the slot 26: this post therefore centr~lices the unit longit~A;n~lly, without interfering with its flexure.
The outer posts 23 each have a pivot pin 27 projecting through them, parallel with the axis or axes of flexure of the blade unit, and these pins 27 are received in and guided by elongate slots 28 formed in the walls of the slots 26, so that they accommodate flexure of the blade unit, which is accompanied by movement of the ends of 25; the unit towards and away from each other. The pins 27 also ~L~V~ withd,~ 1 of the blade unit from the handle.
- ~ The posts 23 are set in from the ends of the : unit 80 as to permit the blade unit to flex convexly if -one or both ends cnco~ter larger forces during shaving than the medial portion of the unit. ;
-~ In order to protect the blade unit from damage .J ;due to -~ce~sive flexure in both cun~ve and CGIlveX
~modes it has been found .~c~ess~ry to limit deflection both at the c~nLLa and at~the ends of the cartridge.
~ : In the-concave mode, deflection from the unflexed plane is limited by abutment of the underside .
, :
W092/06827 2 ~ ~ 2 5 3 2 PCT/US91/07468 f: .
of the platform with the cenLle of the head of the handle. In the convex mode, deflection of the outer portions of the blade unit is limited by abutment of the underside of the outer portions of the platform with outer portions of the handle head.
In a particular embodiment the concave deflection is limited to 2.5 mm at the ce,.~,e, and the convex deflection is limited to 3 mm at the ends, of the blade unit. The ~p~cinq of the outer posts 23 is preferably 2/3 of the overall length of the blade unit.
The main forces en-oun~ered during shaving are directed perp~nAic~ r to the plane of the hlA~Pc (or blade) and passing through a region bordered by the cutting edges of a tAn~ blade unit. Since the posts 23,24 are aligned with those forces, they do not ~nCou~Ler any substantial b~n~;nq moment which would otherwise tend to tilt them and create a tQndency for the pins 27 to bind in the guide slots 28.
Whilst we have de6cribed an . ~ ment in which the polyethylene oxide .~o~Ain;nq moulding is made separately from the housing 11 and is adhesively hon~ed to the latter, the polyethylene oxide COII~ ~;n;ng moulding can be made in ~i~ by a two stage moulding plocess, namely a y~oce88 in which different materials are moulded into a single component by moulding one material first and then ll~;nq the seco~ n situ.
This y uaess can be used to mould the housing and the polyethylene oYi~e ~ollLA;ninq mo~ ;ng as a single component (fipAc;nq pieces being inserted into the mould before the injection of the polyethylene oxide-cont~;n~nq mixture to provide the de6ired gaps between the cap teeth and the teeth of the polyethylene oxide-cont~ininq moulding. This eliminates the need for A~he6;Ve ho~ing and the ~du~ion in the flexibility of the unit which might arise from the use of an adhesive.
The blade unit is flexible in the sense that it is readily flexible, in ~U~Jl~ce to forces encuul.Lered during no -1 use, about an axis or axes parallel with the plane of the blade unit and exten~i ng substantially perpendicular to the cutting edge(s) of the blade(s).
