Definitions

  • the present invention is directed to a flexible razor head and, more particularly, to a one-piece, integrally formed, flexible razor head.
  • Razor heads which are flexible along their longitudinal axes have been disclosed in the art. Many of these razor heads require the assembly of several separate pieces such as a cap, a spacer, one or more blades and a blade platform. This assembly process is time consuming and costly. Furthermore, the requirement that these pieces are manipulated, either manually or automatically, is generally considered to place restrictions on the type of materials which may be used in their manufacture. The materials used must be substantially rigid to withstand the assembly process while meeting the specification tolerances necessary to properly join with the other pieces. It would, therefore, be desirable to provide a flexible razor head having integrally formed elements which would therefore eliminate the need for the assembly of a number of elements.
  • EP-A-0 470 720 discloses a twin blade razor head comprising:
  • EP-A-0 470 720 does not discuss the manner in which the vibration of the blades of the razor head may be minimised.
  • the present invention overcomes disadvantages of previously disclosed razor heads by providing an integrally formed flexible razor head having a plurality of blade platforms separated by corrugations, at least one blade having a cutting edge, and a plurality of blade retainers which are integrally formed with the blade platforms and extend to positions above and adjacent to the top surface of the upper blade. While the blade retainers are integrally formed with the other pieces of the flexible razor head, each blade retainer is discrete with respect to other blade retainers.
  • the integrally formed flexible razor head of the present invention therefore, does not have a continuous cap member commonly found in commercially available razor heads.
  • the razor head of the invention is characterised in that the razor unit is moulded so that both the cap blade and the seat blade are supported equally by plastic material.
  • Figure 1 is a perspective view of a flexible razor head not forming part of the invention, but illustrating subject matter forming part of the background to the invention.
  • Figure 2 is a side view of the razor head shown in Figure 1.
  • Figure 3 is a top, perspective view of the razor head shown in Figure 1.

  • Figure 8 is a top view of an upper blade of the razor head shown in Figure 1.
  • Figure 9 is a sectional view taken along lines 9-9 of Figure 3.
  • Figure 10 is a cross-sectional view taken along lines 10-10 of Figure 3.
  • Figure 11 is a cross-sectional view along line 11-11 of Figure 4.
  • Figure 12 is a cross-sectional view of the upper portion of a razor head not forming part of the invention but illustrating a shaving aid receptacle, forming part of the background of the invention.
  • Figure 13 is a cross-sectional view illustrating the positioning of a shaving aid in Figure 12.

  • Figure 20 is a cross-section taken along lines 20-20 of the embodiment shown in Figure 19.
  • Figure 21 is an enlarged detail of the cross-sectional view shown in Figure 20.
  • the present invention comprises an integrally-molded, flexible razor head wherein all elements, except the blade or blades, are formed as a single piece.
  • the integral formation of the present flexible razor head eliminates the time consuming and costly assembly steps necessary in the manufacture of flexible razor heads formed of separate pieces.
  • the flexible razor head of the present invention also provides controlled shaving geometry without the use of a continuous cap found in most commercially available razor heads.
  • the term "razor head” is meant to include cartridges which are manufactured and typically marketed separate from razors, as well as disposable razors which are formed with a handle and do not require the attachment of separate pieces by the consumer.
  • Figure 1 illustrates a flexible razor head 10 comprising an upper blade 20, a lower blade 30, a plurality of discrete retaining members 40, guard members 50, and side supports 80.
  • Figure 2 is a side view of the flexible razor head illustrated in Figure 1 showing the side portion of side supports 80, as well as a side view of attachment neck 90.
  • FIG 3 is a top view of the razor head illustrated in Figure 1.
  • This top view also provides a clearer view of the relative positioning of cutting edges 21, 31 of upper blade 20 and lower blade 30, respectively.
  • Blade retainers 40 overlap upper blade 20, preferably extending at least about 50% and most preferably about 70% to about 90% of the distance from the rear edge of upper blade 20 to cutting edge 21.
  • the retainer members 40 which are integrally formed with blade platform 70 and spacer 100 (Fig. 10) thereby maintain the vertical positioning of the blades.
  • blade retainers 40 are discretely formed without connections and therefore do not form a single, unitary cap member found in many commercially available razor heads. As illustrated in Figure 3, the two end blade retainers 40 are connected to respective side supports 80 via molded connecting member 83. Connecting members 83 are designed to minimize the risk of exposure of either or both of the blades if the razor head 10 is misused by a person applying an outward, lateral force to side supports 80.
  • side supports 80 comprise upper side retainers 81 and lower guard portions 82.
  • Upper side portions 81 are located above and adjacent to the upper blade 20 to retain the upper blade against the spacers 100 and also to control the blade geometry along the side portions of the flexible razor head 10.
  • lower guard portions 82 cover the forward corners of lower blade 30 while also serving as a guard member to control the blade geometry.
  • the bottom of lower blade 30 can be seen supported by a plurality of blade platforms 70 which are integrally formed with corrugations 60.
  • Each platform 70 preferably has a substantially planar upper portion 76 adjacent to lower blade 30.
  • a spacer 100 is preferably provided between upper blade 20 and lower blade 30 proximate each retaining member 40.
  • the spacer 100 is preferably positioned substantially centrally with respect to the width of the corresponding blade retainer 40 and blade platform 70.
  • Spacer 100 maintains a predetermined space, for example about 0.5 mm (.02 inches), between lower blade 30 and upper blade 20.
  • spacer 100 is integrally formed with blade retainer 40.
  • flexible razor head 10 is provided with corrugations 60 between adjoining blade platforms 70.
  • the corrugations are integrally formed with retainer members 40.
  • the positioning of corrugations 60 on both sides of a blade platform 70 is shown in Figure 10 which is a cross-sectional view along lines 10-10 of Figure 3.
  • Corrugations 60 may be formed in a generally U-shape with a rounded lower portion or may be formed with two vertical side portions and a lower horizontal segment connecting the vertical side walls. Other shapes are possible.
  • Corrugations 60 allow relative movement between neighboring blade platforms 70 during the flexing of flexible razor head 10.
  • the use of discrete blade platforms 70 connected by a corrugation 60 minimize the potential for separation between the upper supporting surface of blade platform 70 and the bottom of lower blade 30. In this manner, the correct blade geometry is maintained at each point along the flexible razor head 10 even during flexing which occurs during shaving.
  • corrugation is meant to include a resilient connector disposed between adjoining blade platforms and having a length greater than the "normal" distance between those adjoining blade platforms, i.e. the gap existing when the flexible razor head is in a substantially linear configuration and is not subject to external forces such as those encountered during shaving.
  • the corrugations are longer than the "normal” distance and are preferably at least about 20% longer than the normal distance.
  • the corrugations may be formed with sidewalls having sections with different thicknesses in order to further increase the flexibility of the blade support.
  • a guard support 55 depends downwardly and forwardly from each blade platform 70 in the illustrated preferred embodiment. As illustrated more clearly in the bottom view of Figure 6, each guard support 55 extends from a rearward position between corrugations 60 to a position forward of cutting edge 31 to support guard members 50.
  • discrete guard members 50 provide a function similar to a continuous guard bar in providing a suitable blade geometry to the flexible shaving head 10, while providing greater flexibility than a conventional continuous guard bar formed of the same materials.
  • FIGs 7 and 8 illustrate an upper blade 20 and a lower blade 30, respectively.
  • Both upper blade 20 and lower blade 30 comprise a forward cutting edge 21, 31 and side positioning slots 23, 33 and 24, 34.
  • left side slots 23, 33 may be formed with a shape different from right side slots 24, 34 in order to ensure proper positioning within a mold cavity.
  • Each blade is also preferably provided with a generally centrally located hole 25, 35.
  • a securing member 105 which is integrally formed with central blade retainer 40 and central blade platform 70, passes through both of these centrally located holes 25, 35. As illustrated, these central holes 25, 35 are the only positions where a securing member passes entirely through both blades.
  • left position hole 38 also receives some thermoplastic material which also may tend to fasten lower blade 30 to a corresponding blade platform 70.
  • upper blade 20 receives thermoplastic material through oblong, right positioning hole 29 but not at left positioning hole 28.
  • Razor head 10 is preferably formed by injection molding by first placing lower blade 30 into a mold with locating pins extending from the bottom of the mold cavity through positioning holes 38 and 39. A mold cavity spacer is then positioned on top of bottom blade 30 and upper blade 20 is then positioned on the same positioning pins which extend through positioning holes 28, 29. The placement of the blades 20, 30 on the pins is facilitated by providing each blade with one oblong positioning hole as illustrated. Those skilled in the art will appreciate that the mold member positioned between the blades is designed to prevent the flow of thermoplastic material where such material is not ultimately desired.
  • thermoplastic material such as polypropylene
  • polypropylene a thermoplastic material
  • polyethylene other material may be used in the preferred molding process of the present invention such as polyethylene.
  • Polypropylene has been found to be desirable since it allows the desired amount of flexibility and cost effective manufacturing while providing adequate support for the blades and sufficient rigidity to maintain the desired blade geometry.
  • Polypropylene also provides a low mold temperature relative to other materials known in the art for the formation of razor heads. This low mold temperature is desirable since a shaving aid is to be added to the flexible razor head in a sequential molding process.
  • the flexible razor head is adapted to be supported by a razor mechanism (illustrated partially in phantom in Fig. 9) having outwardly biased attachment members.
  • the illustrated flexible razor head 10 is shown in Figure 6 as having an attachment slot 110 defined by outer sidewalls 115 and 120, inner wall 135, outer wall 140, and slot cover plates 150 and 160 having inner edges 151 and 161, respectively.
  • Inner wall 135 has an inner wall slot 180 defined by inner side walls 125 and 130.
  • the slot cover plates 150 and 160 cover the outer ends of the slot 110 but, as shown in Figure 6, leave a portion of the inner end of slot 110 and the entire central region of slot 110 uncovered for the passage of an attachment member of a razor.
  • the outwardly biased arms are advantageously designed to maintain the razor cartridge in a substantially linear configuration in the absence of shaving forces.
  • attachment neck 90 is designed to provide a greater bearing surface for a razor attachment member (shown in phantom) thereby reducing the potential for flexible razor head to rock when attached to a razor mechanism.
  • a flexible razor head of the present invention may be designed to receive one or more additional elements such as a shaving aid in a subsequent molding or assembly step.
  • a blade retainer may be formed with depressions designed to receive a shaving aid.
  • the completed flexible razor head is then subjected to a supplemental molding step wherein a shaving aid is sequentially molded into the recesses in the blade retainers.
  • Figures 12 to 14 The result of this process is illustrated in Figures 12 to 14, in which one or more of the blade retainers 140 is initially molded with a receptacle 142 having flexible sidewalls 143.
  • the initially molded flexible razor head is then subjected to a subsequent molding step wherein side walls 143 are first bent downwardly into receptacle 142 and then a shaving aid is injected into receptacle 142.
  • Figures 13 and 14 illustrate the final positioning of the shaving aid 145 on blade retainers 140.
  • the cut away view of Figure 14 illustrates the positioning of sidewall 143 below the shaving aid 145 in the final flexible razor head of this embodiment.
  • Exemplary materials constituting the shaving aid may comprise one or various combinations of the following:
  • the configuration of the shaving aid, its place of application to the razor cartridge, the manner of attachment and/or other means and method of incorporation may vary widely to fit particular requirements.
  • razor head 10' is a one piece continuous thermoplastic body in which the blades are secured substantially rigidly against movement and vibration during shaving.
  • shave geometry As is known in the shaving industry, the design and positioning of the cap portion and guard bar of the razor head with respect to the cap and seat blades create what is commonly referred to as a "shave geometry.” A proper shave geometry is an important factor in ensuring a comfortable and a smooth shave.
  • FIG. 15 shows the addition of a skin flow control rail 200 and a shaving aid 210 which includes corrugations 211 to permit flexing during shaving.
  • Razor head 10' has also been insert molded so that the guard members 50' are interconnected and continuous with skin flow control rail 200.
  • razor head 10' is also provided with flow-through rinse slots 220.
  • Shaving debris tends to accumulate between the cap and seat blades during shaving. This debris, which can detract from the effectiveness of the razor unit, is often difficult to remove by rinsing alone. This difficulty in removing the shaving debris which becomes lodged between the blades often forces the user to have to "tap" the razor head against the sink, counter, etc. to clear the blades.
  • Razor head 10 addresses this concern by incorporating rinse slots 220 in the back surface of the head.
  • the slots are positioned between the blades such that a flow of water directed into the slots from the rear of the razor unit will dislodge any shaving debris trapped between the blades.
  • FIGs. 19-21 An embodiment of the present invention is illustrated in Figs. 19-21.
  • razor unit 10'' is molded so that both the cap blade and the seat blade are supported equally by plastic.
  • the amount of unsupported seat blade i.e., length X 1
  • the amount of unsupported cap blade i.e., length X 2 ).
  • Phantom lines A, B, and C depict the additional continuous body sections a, b, and c which distinguish this preferred embodiment.
  • Body segments a, b and c perform basically two functions.
  • the additional body segments equalize length X 1 and length X 2 so that the vibration cycle of the blades will begin substantially simultaneously when an impact force is exerted on the blades. In other words, the blades are synchronized and will vibrate together, thereby ensuring that the span between the blades remains substantially constant during shaving.
  • the additional plastic increases the rigidity of the blades, which, in turn, decrease the amplitude of any vibration in the blade. Ideally, the amplitude of any vibration in the blades should be maintained as low as possible to ensure that the razor head is providing the user with a comfortable and close shave. Both of these features enhance the ability to maintain shave geometry over the entire length of the shaving unit during shaving.
