Full Text | RAZOR HEAD HAVING SEPARATELY ATTACHED PARTS AND METHOD OF PRODUCING THEREOF Field of the invention The invention relates to safety razors and, more specifically, to a method of producing a razor blade unit. Background of the invention US patent No. 6,430,818 to Wonderley discloses a blade shaving cartridge including a blade seat, several blades, a spacer and a cap member. The cap member includes a plurality of staking pins which permanently affix the blade seat, blades, spacer and cap member together. One disadvantage of such a structure is that it is not totally safe. When the pins break, which sometimes occurs because the pins are not strong enough, the different pieces scatter apart, thereby increasing the risk that the users cut themselves. Summary of the invention It is an object of the invention to provide a razor structure which is safer. It is also an object of the invention to provide a method of producing a razor blade unit which is simpler. The method of producing a razor blade unit according to the invention comprises the steps of: - providing a guard member having a lower surface and including securing pins protruding from said lower surface, - securing a blade unit onto said guard member, - providing a cap member, and - securing said cap member onto said guard member, wherein the step of securing the blade unit onto said guard member comprises the steps of: - providing at least a first blade having apertures in alignment with said pins, - mounting said first blade onto said guard member, said securing pins passing through said securing apertures, forming a crimping head at one end of each securing pin, thereby riveting said first blade onto said guard member. Thus, the cap member and the blades are secured separately onto the guard member. The cap member can be strongly secured to the guard member without the risk that the blades be broken. In addition, the securing pins are shorter and thus stronger, so that there is less risk that the pins'break. The step of securing the blade unit onto said guard member may comprise the further steps of: - providing a spacer having holes in alignment with said securing pins, - mounting said spacer onto said first blade, said securing pins passing through said holes, - providing a second blade having securing apertures in alignment with said pins, - mounting said second blade onto said spacer, said securing pins passing through said securing apertures/ and - forming a crimping head at one end of each securing pin, thereby riveting said blades onto said guard member. The step of securing the blade unit onto said guard member may comprise the further steps of: - providing a second spacer having holes in alignment with said securing pins, - mounting said second spacer onto said second blade/ said securing pins passing through said holes, - providing a third blade having securing apertures in alignment with said pins, - mounting said third blade onto said second spacer, said securing pins passing through said securing apertures, and - forming a crimping head at one end of each securing pin, thereby riveting said blades onto said guard member. The step of securing the blade unit onto said guard member may comprise the further steps of: - providing a spacer having holes in alignment with said securing pins, - mounting said spacer onto said third blade, said securing pins passing through said holes, - providing a fourth blade having apertures in alignment with said pins, - mounting said fourth blade onto said spacer, said securing pins passing through said securing apertures, and - forming a crimping head at one end of each securing pin, thereby riveting said blades onto said guard member. The step of securing the blade unit onto said guard member may further comprise the steps of: - providing a securing plate having holes in alignment with said pins, - mounting said securing plate onto the last blade, said securing pins passing through said holes, - forming a crimping head at one end of each securing pin, thereby sandwiching said blades between said guard member and said securing plate. The cap member may be laser welded onto said guard member. In this case, the guard member has e.g. a peripheral wall defining, together with said lower surface, an internal volume in which the blade unit is disposed, and the cap member is laser welded onto an edge of said securing pins passing through said securing apertures, and - forming a crimping head at one end of each securing pin, thereby riveting said blades onto said guard member. The step of securing the blade unit onto said guard member may comprise the further steps of: - providing a spacer having holes in alignment with said securing pins, - mounting said spacer onto said third blade, said securing pins passing through said holes, - providing a fourth blade having apertures in alignment with said pins, - mounting said fourth blade onto said spacer, said securing pins passing through said securing apertures, and - forming a crimping head at one end of each securing pin, thereby riveting said blades onto said guard member. The step of securing the blade unit onto said guard member may further comprise the steps of: - providing a securing plate having holes in alignment with said pins, - mounting said securing plate onto the last blade, said securing pins passing through said holes, - forming a crimping head at one end of each securing pin, thereby sandwiching said blades between said guard member and said securing plate. The cap member may be laser welded onto said guard member. In this case, the guard member has e.g. a peripheral wall defining, together with said lower surface, an internal volume in which the blade unit is disposed, and the cap member is laser welded onto an edge of said peripheral wall, thereby closing said internal volume. The cap member may be an adapter mateable with a razor handle. According to another aspect of the invention, there is provided a razor head having a guard member, a blade unit attached to the guard member in an internal volume thereof and a cap member attached to the guard member to close said internal volume, said blade unit and said cap member being attached separately to the guard member.

Attachment of the razor head 1 to a handle end is described in further details in US patent nr. 4,492,025, the whole content of which is herewith incorporated by reference. A method of producing a razor head I according to the invention is described hereinafter. Such a method comprises the steps of: - providing platform guard 2; - securing blade assembly 3 onto the platform guard 2; - providing platform rear cap 4; - securing the platform rear cap 4 to the platform guard 2 on the same side as the blade assembly 3. Depending on the number of blades in the blade assembly 3, several embodiments are provided for carrying the step of securing the blade assembly 3 onto the platform guard 2. One blade In a razor head 1 having one blade 25 only, the step of securing the blade assembly 3 onto the platform guard 2 comprises the steps o'f: - providing the blade 25 with the securing apertures 32 and the cut-outs 33, 34 in alignment with the securing pins 16 and the positioning pins II, 18, respectively; - mounting the blade 25 onto the platform guard 2, the blade 25 abutting against the internal surface 12 of the base member 6, the securing pins 16 passing through the securing apertures 32, the positioning pins 17, 18 cooperating with the cut-outs 33, 34, the blade ends 23, 24 abutting against tapered surfaces 19, 20 and the blade edge 31 extending through and along the rectangular opening 9 in the platform guard 2; - providing a securing plate (i.e. spacer 28) with the holes 35 thereof in alignment with the securing pins 16; - mounting the securing plate 28 onto the platform guard 2, over the blade 25; - forming a crimping head 54 at one end of each securing pin 16, thereby riveting the one-blade assembly 3 onto the platform guard 2.

Three blades (preferred) In a razor head 1 having three blades 25, 26, 27 (depicted on figure 3), the step of securing the blade assembly 3 onto the platform guard 2 comprises the steps of: - providing a narrow or primary blade 25 with the securing apertures 32 and the cut-outs 33, 34 in alignment with the securing pins 16 and the positioning pins 11, 18, respectively; - mounting the primary blade 25 onto the .platform guard 2, the blade 25 abutting against the internal surface 12 of the base member 6, the securing pins 16 passing through the securing apertures 32, the positioning pins 17, 18 cooperating with the cut outs 33, 34, the blade ends 23, 24 abutting against tapered surfaces 19, 20 and the blade edge 31 extending through and along the rectangular opening 9 in the platform guard 2; - providing a primary spacer 28 with the holes 35 in alignment with the securing pins 16; - mounting the primary spacer 28 onto the platform guard 2 over the primary blade 25, the securing pins 16 passing through the holes 35 of the primary spacer 28; - providing a secondary blade 26, the securing apertures 32 and the cut-outs 33, 34 being in alignment with the securing pins 16 and the positioning pins 17, 18, respectively; - mounting the secondary blade 26 onto the platform guard 2 over the primary spacer 28, the securing pins 16 passing through the securing apertures 32, the positioning pins 17, 18 cooperating with the cut-outs 33, 34, the blade ends 23, 24 abutting against tapered surfaces 19, 20, and the blade edge 31 extending through and along the rectangular opening 9 provided in the platform guard 2; - providing a wide or tertiary blade 27 with the securing apertures 32 and the cut-outs 33, 34 in alignment with the securing pins 16 and the positioning pins 17, 18, respectively; - mounting the tertiary blade 27 onto the platform guard 2 over the secondary spacer 29, the securing pins 16 passing through the securing apertures 32, the positioning pins 17, 18 cooperating with the cut-outs 33, 34, the blade ends 23, 24 abutting against tapered surfaces 19, 20 and the blade edge 31 extending through and along the rectangular opening 9 provided in the platform guard 2; - providing a securing plate 30 with holes 35 in alignment with the securing pins 16; - mounting the securing plate 30 onto the platform guard 2 over the tertiary blade 27; - forming a crimping head 54 at one end of each securing pin 16, thereby riveting the three-blade assembly 3 onto the platform guard 2. Four blades In a razor head having four blades, the step of securing the blade assembly onto the platform guard comprises the steps of: - providing a narrow or primary blade with the securing apertures and the cut-outs in alignment with the securing pins and the positioning pins, respectively; • mounting the primary blade onto the platform guard, the blade abutting against the internal surface of the base member, the securing pins passing through the securing apertures, the positioning pins cooperating with the cut-outs, the blade ends abutting against tapered surfaces and the blade edge extending through the rectangular opening in the platform guard; providing a primary spacer with the holes in alignment with the securing pins; mounting the primary spacer onto the platform guard over the primary blade, the securing pins passing through the holes of the primary spacer; providing a secondary blade, the securing apertures and the cut-outs being in alignment with the securing pins and the positioning pins, respectively; mounting the secondary blade onto the platform guard over the primary spacer, the securing pins passing through the securing apertures, the positioning pins cooperating with the cut-outs, the blade ends abutting against tapered surfaces and the blade edge extending through the rectangular opening provided in the platform guard; providing a wide or tertiary blade with the securing apertures and the cut-outs in alignment with the securing pins and the positioning pins, respectively; mounting the tertiary blade onto the platform guard over the secondary spacer, the securing pins passing through the securing apertures, the positioning pins cooperating with the cut-outs, the blade ends abutting against tapered surfaces and the blade edge extending through the rectangular opening provided in the platform guard; - providing a tertiary spacer with holes in alignment with the securing pins; - mounting the tertiary spacer onto the platform guard over the tertiary blade; - providing a fourth blade, wider than the tertiary blade, the securing apertures and the cut-outs of the fourth blade being in alignment with the securing pins and the positioning pins, respectively; - mounting the fourth blade onto the platform guard over the tertiary spacer, the securing pins passing through the securing apertures, the positioning pins cooperating with the cut-outs, the blade ends abutting against tapered surfaces and the blade edge extending through the rectangular opening in the platform guard; - providing a securing plate with holes in alignment with the securing pins; - mounting the securing plate onto the platform guard, the securing pins passing through the holes; - forming a crimping head at one end of each securing pins, thereby riveting the blade assembly onto the platform guard. Accordingly, no matter the number of blades, the step of riveting the blade assembly 3 to the platform guard 2 is achieved before the step of mounting the platform rear cap 4. In other words, the blade assembly 3 is fixed to the platform guard 2 separately and independently from the platform rear cap 4, so that, in case an accidental separation of the platform rear cap 4 from the platform guard 2 occurs, scattering of the blades is avoided. In addition, since the blade assembly 3 is fixed to the platform guard 2 independently from the platform rear cap 4, it is possible to strongly fix the latter to the platform guard 2, as described hereinafter. Furthermore, since the securing pins 16 hold the blade assembly 3 only, which is sandwiched by the securing plate, the securing pins are shorter than the ordinary ones, so that they are stronger and there is less risk that the blades be accidentally detached from the platform guard 2 . As illustrated in figures 2 and 5, the platform rear cap 4 forms a cover which, when secured onto the platform guard 2, closes the internal volume 8 wherein the blade assembly 3 is unreachably lodged. Of course, the thickness of the platform guard 2, i.e. the height of the peripheral wall 7, shall be adapted to the thickness of the blade assembly 3, depending on the number of blades. As depicted on figure 5, after the blade assembly 3 has been riveted, the crimping heads 54 do not project outside from the internal volume 8 of the platform guard 2, so that when mounted onto the platform guard 2, the platform rear cap 4 is not prevented from abutting against the peripheral wall 7 of the platform guard 2. As further depicted on figure 5, the platform rear cap 4 is laser welded onto the platform guard 2. There is provided a laser source which is connected to a laser welding head 55 through a flexible laser beam guiding element 56. The laser welding head 55 is mounted onto an arm 57 which is, in turn, slidingly mounted on a clamping element 58 in a direction perpendicular to an interface 59 between the platform rear cap 4 and the platform guard 2, as shown by arrow Fl. Moreover, the laser welding head 55 is slideable, with respect of the clamping element 58, in both directions in a plan substantially parallel to the interface 59 between the platform rear cap 4 and the platform guard 2, so that the laser welding head 55 can move along a predetermined welding path 60 illustrated in figure 6, which follows the contour of the peripheral wall 7. In a preferred embodiment illustrated in figure 5, platform guard 2 is mounted on the bottom side of the assembly, while the platform rear cap 4 is mounted on the top thereof. As a laser beam 61 comes from the top, the platform rear cap 4 and the platform guard 2 have to be made of suitable polymers in order to allow laser welding. In this particular case, platform rear cap 4 has to be transparent to the laser beam 61 while platform guard 2 has, on the contrary, to be absorbing. As the laser wave length is outside the visible range, both pieces 2, 4 may be dyed according to the wishes of the manufacturer, provided that they present sufficient transparency and opacity to the laser beam 61, respectively. Besides, the interface 59 formed by overlapping of the platform rear cap 4 and the platform guard 2 (i.e. by conjunction of rim 38 and top surface 39) must be of sufficient area to prevent the welding path or melting zone 60 from reaching the edges of the interface 59. The laser welding method is described in further details in US patent nr. 6,201,211, the whole content of which is herewith incorporated by reference. As described here above, this welding method is used to laser weld the platform rear cap 4 to the platform guard 2, since there is a need for strongly securing both pieces 2, 4 to each other in order to avoid separation during shaving, which could injury the user's face (or other body areas to be shaved) . There is also a need for preventing a child who would be playing with the razor from easily separating the platform rear cap 4 from the platform guard, thereby easily accessing the blades. Laser welding could also be used to weld other plastic parts of the razor, which need to be strongly secured together. For instance, in a razor having a handle comprising several plastic parts, the method of producing the razor according to the invention comprises a step of laser welding together at least two plastic parts of the handle. The technique of laser welding may be the same as previously recited. Therefore, one of the plastic part has to be transparent in order to allow transmission of the laser beam, while the other part has to be absorbing. The one part may be an upper member of the handle and the other a lower member, the upper and the lower members being laser welded together to form the whole handle. A decorative insert (e.g. for an advertising purpose) may be sandwiched between the upper and the lower members, the insert being visible through the transparent upper member. CLAIMS 1.
