    FIELD OF THE INVENTION
    [001] The embodiments of the present invention relate to razor cartridges for shaving and hair removal and apparatus for shaving and hair removal that have such razor cartridges for shaving and hair removal. BACKGROUND OF THE INVENTION
    [002] In particular, the present invention relates to a razor cartridge for shaving and hair removal comprising: - a housing that extends along a longitudinal geometric axis, which has an upper side, a lower side opposite the upper side and two longitudinal sides that extend longitudinally along the longitudinal geometric axis between the upper and lower sides, - a cutting blade mounted in the housing between the longitudinal sides and having a cutting edge that extends along the longitudinal geometric axis, - a retainer that holds the cutting blade in the housing.
    [003] U.S. Patent No. 4,443,940 discloses a razor cartridge for shaving and shaving that comprises a housing and cutting blades. In a first embodiment of U.S. Patent No. 4,443,940, a portion of the housing partially covers the cutting blades. This portion allows the cutting blades to be kept in the housing. In another embodiment, the cutting blades are held by the bridges that form a retainer. The retainer is integrally formed with a cover member and a partial protection member and is then pressed into the housing. Such a retainer is not attached and can reduce the safety of the blade after the cartridge is assembled. In addition, the manufacture of such a retainer can be long, and the assembly requires strict tolerances to be applied.

    [014] In the different Figures, the same reference signs designate similar or similar elements. DESCRIPTION OF REALIZATIONS OF THE INVENTION
    [015] Figures 1, 2, 4, 5A, 5B show a razor cartridge for shaving and hair removal 1 of a wet shaving and hair removal device 3, the blades 5 of which are not driven by a motor, in in relation to the razor cartridge for shaving and epilation 1.
    [016] As seen in Figure 11, the razor and shaving blade cartridge 1 can be attached to a cable 7 that extends in a direction of the cable between a proximal portion Pp and a distal portion Dp. The cable 7 can rotate in relation to the razor cartridge for shaving and epilation 1. In other embodiments, the cable 7 can also be fixed in relation to the razor cartridge for shaving and epilation 1. The cable direction can be curved or include a or several straight portions. The razor and shaving blade cartridge 1 can, for example, be releasably connected to the shaving and shaving appliance cable 7 via a release and locking mechanism.
    [017] As depicted in Figures 1, 2, 4, 5A, 5B, the razor and shaving cartridge 1 comprises a housing 9. The housing 9 extends along a longitudinal geometric axis X-X. Viewed from the top, housing 9 has a general rectangular shape. However, in some embodiments, the general shape of the housing 9 may be different and, for example, the housing 9 could have an oval shape, a square shape or a circular shape. The housing 9 comprises an upper side 11, a lower side 13, opposite the upper side 11, and a first and a second longitudinal side 15, 17. For example, the lower side 13 is adapted to be disposed in front of the cable 7, while that the upper side 11 is disposed opposite the lower side 13. The upper layer 11 and the lower layer 13 can be parallel to each other.
    [018] The first longitudinal side 15 extends along the longitudinal geometric axis X-X. The second longitudinal side 17 and the first longitudinal side 15 face each other. The second longitudinal side 17 can be approximately parallel to the first longitudinal side 15, especially when the first and second longitudinal sides 15, 17 are flattened. However, the first and second longitudinal sides 15, 17 can also have notable or subtle opposite slopes. The first and second longitudinal sides 15, 17 can also have curved surfaces. The second longitudinal side 17 also extends along the longitudinal geometric axis X-X. Each between first and second longitudinal side 15, 17 extends in a lateral direction Z, along a lateral geometric axis Z-Z, between the upper side 11 and the lower side 13 of the housing 9. The first side 15 can be at the front or rear of the blade edges, according to the realization. The lateral geometric axis Z-Z intersects the longitudinal geometric axis X-X. For example, the longitudinal axis X-X and the lateral axis Z-Z can be orthogonal to each other.
    [019] The housing 9 may also comprise, as best seen in Figures 1, 2 and 4, the first and the second side sides 19, 21 which extend between the first and the second longitudinal sides 15, 17, along a transverse geometric axis YY. The transversal geometric axis Y-Y is transversal to the longitudinal geometric axis X-X. The transverse geometric axis Y-Y can be, for example, orthogonal to the longitudinal geometric axis X-X and to the lateral geometric axis Z-Z. The first and second lateral sides 19, 21 are arranged, in the lateral direction Z, between the upper side 11 and the lower side 13. The first and second longitudinal and lateral sides 15, 17, 19, 21 together form the outer surface of the housing 9.
    [020] Both the first and the second side sides 19, 21 join the longitudinal ends 23, 25 of the first and second longitudinal sides 15, 17. Similarly, both the first and the second longitudinal sides 15, 17 join the ends free 27, 29 of the first and second side sides 19, 21. The housing 9 may comprise a plastic material. However, other materials could be used. For example, the housing could comprise a metallic material. In addition, the housing can be produced with a combination of two or more different materials. For example, a part of the housing can be produced from a first material, while the other part of the housing is made from a second material.
    [021] The housing 9 may, for example, include, on the lower side 13, a connection mechanism 31 adapted to connect the cable 7. The connection mechanism 31 can thus allow the release and / or fixation of the cartridge razor and shaving blade 1 to handle 7.
    [022] The housing 9 also comprises a slide receiving section 33, as shown in Figure 2. The slide receiving section 33 or slide receiving area may have a general rectangular shape. The blade receiving section 33 is arranged on the upper side 11 of the housing 9. The blade receiving section 33 defines a recess and is adapted to receive at least one cutting blade 35. In other words, the razor cartridge for shaving and epilation 1 comprises at least one cutting blade 35 (also called blade in the remainder of the description). As depicted in Figures 1, 2, 4, 5A, 5B, 8, 11, the razor and shaving blade cartridge comprises three cutting blades. However, in other embodiments, the razor and shaving blade cartridge 1 may comprise more or less than three cutting blades 35. For example, the razor and shaving blade cartridge 1 may comprise five cutting blades.
    [023] The cutting blades 35 are mounted in the housing 9, in the blade receiving section 33, between the first and the second longitudinal sides 15, 17 of the housing 9 and between the first and the second side sides 19, 21 of the housing 9 As shown in Figures 1, 2 and 4, each blade 35 extends longitudinally along the longitudinal geometric axis XX. Each cutting blade 35 comprises a first and second ends 37, 39 along the longitudinal geometric axis XX and is directed towards the first longitudinal side 15. The first end 37 of the cutting blades 35 is directed towards the first lateral side 19 of the housing 9, while the second end 39 of the cutting blade 35 is directed towards the second side side 21 of the housing 9. Each cutting blade 35 comprises a cutting edge 41. The cutting edge 41 extends along the longitudinal geometric axis XX. The cutting edge 41 of the cutting blade 35 is accessible at the upper side 11 of the housing 9 to cut the hair during shaving / epilation.
    [024] For example, the cutting blades 35 are L-shaped, as shown in Figures 3, 5A and 5B. The cutting blades 35 thus have a cutting edge portion 43, a guided portion 45 and an inclined portion 47, which is intermediate between the cutting edge portion 43 and the guided portion 45. The cutting edge portion 43 extends along of a cutting edge portion axis. Advantageously, the cutting edge portion axis of all cutting blades 35 is positioned parallel to each other.
    [025] In one embodiment, each cutting blade 35 is freely assembled in the housing 9, as best seen in Figures 3, 5A and 5B. More precisely, the cutting blades 35 are movably mounted on the blade receiving section 33. Each cutting blade 35 is, for example, supported by two elastic fingers. The elastic fingers can be molded as one piece with the housing 9 and can extend in the blade receiving section 33, towards each other and upwards, from both side sides 19, 21 of the housing 9. As shown in Figures 3, 5A and 5B, the guided portions 45 of the cutting blades 35 are slidably guided in slots 53 provided in the housing 9. For example, the cutting blade 35 can be provided with its cutting edge 41, fixed on a support blade 57 comprising the guided portion 45 and the inclined portion 47. In that case, blade support 57 is performed by the elastic fingers.
    [026] However, in some other embodiments (not shown in the Figures), the blades could be inclined blades, as described, for example, in patent application No. WO2013 / 050606 or curved blades.
    [027] Each cutting blade 35 is retained in the housing 9 by a retainer 59. The retainer 59 is retained in the housing by a rivet 61. The rivet 61 is best represented in a cross-sectional view in Figure 3. The rivet 61 forms a permanent mechanical (non-detachable) fastener of the retainer in the housing 9.
    [028] As shown more particularly in Figures 6 and 7, the retainer 61 comprises a retainer body 63 that extends along a first direction D1. The retainer body 63 has a length "L", a width "I" and a thickness "ep". The width "l" of the retainer is preferably sensibly constant along its length "L". In addition, as shown in Figures 6 and 7, the thickness “ep” of the retainer is preferably constant along its length “L”. In other embodiments, the width “l” and thickness “ep” of the retainer could be variable.
    [029] The retainer body 63 comprises a first end 65 and a second end 67 along its length.
    [030] The retainer body 63 comprises a first through hole 69 disposed towards its first end 65. The through hole 69 is located at a non-zero distance from the first end 65 of the retainer body 63. The through hole 69 has, for example, a circular shape. However, other formats could be provided. For example, the through hole can be a rectangular shape or a square shape or an L shape or an oval shape. The through hole 69 is, for example, cut in the retainer body 63. The through hole could also be drilled, for example. In another embodiment, the retainer 59 can be directly formed with the through hole 69.
    [031] In the embodiment depicted in Figures 6 and 7, the retainer body 63 comprises a second through hole 71 disposed towards its second end 67. The second through hole 71 is similar to the first through hole 69. However, in some embodiments , the second through hole 71 could have a shape and / or dimensions that are different from those of the first through hole 69.
    [032] As shown in Figure 6, in a first embodiment, the retainer is, for example, a strip comprising the retainer body 63. The retainer 59 is preferably flattened. Retainer 59 extends along the first direction D1. The first and second ends 65, 67 of the retainer body 63 thus correspond to a free first and second ends of the retainer 73, 75.
    [033] In another embodiment, as shown in Figure 7 and Figures 4, 5A and 5B, retainer 59 has a first leg 77. Retainer body 63 is preferably flattened. Retainer 59 may also have a second leg 79, and the retainer body 63 extends between the first and second leg 77, 79. More particularly, the first leg 77 extends from the first end 65 of the retainer body 63 and the second leg 79 extends from the second end 67 of the retainer body 63. The legs 77, 79 are inclined with respect to the retainer body 63 and extend along a direction substantially orthogonal to the first direction D1. For example, the retainer is fully formed. The legs of the retainer 59 are adapted to be inserted into corresponding recesses provided in the housing.
    [034] For example, the retainer, as shown in Figures 6 and 7, is integrally formed. The retainer can be produced from a material that can be formed, for example, a suitable metal blade. However, other materials can be considered. In another embodiment, the retainer can also be manufactured by injection molding. A polymer material (for example, a reinforced polymer material) can be molded to form the retainer. The retainer can be coated or laminated.
    [035] In the embodiment shown in Figure 7, the legs 77, 79 of the retainer can be tilted. In the event that a polymer material (for example, a reinforced polymer material) is molded to form the retainer, the retainer 59 can be pressed to obtain its final shape.
    [036] The retainer 59 is adapted to be mounted in the housing 9 and then fixed in the housing 9 by a rivet 61.
    [037] In a mounted position of the retainer in the housing, the retainer body extends along the transverse geometric axis Y-Y. The retainer body 63 extends on the upper side 11 of the housing 9. More particularly, the retainer 59 is disposed facing the cutting edge 41 of the cutting blade 35. The first end 65 of the retainer body 63 is directed towards the first longitudinal side 15, while the second end 67 of the retainer body 63 is directed towards the second longitudinal side 17.
    [038] The upper side 11 of the housing 9 comprises a riveting pin 81 that protrudes from the upper side 11 of the housing 9. The riveting pin 81 projects from the upper side 11 of the housing 9, for example, along the geometric axis lateral ZZ, in the opposite direction to the direction of the inferior side. The riveting pin 81 is, for example, made from the same material as the housing 9. For example, the housing 9 and the riveting pin 81 are integrally formed (unitary or monoblocks). However, in some embodiment, the riveting pin 81 could be produced from a different material than the material of the housing 9. The riveting pin 81 could also be mounted on the housing 9, for example, by welding (such as laser welding, etc.). ) or other mounting methods. Riveting pin 81 may have a frustoconical shape. The conical shape facilitates the demoulding of an injection mold. However, riveting pin 81 may have other shapes, for example, a cylindrical shape or a spherical shape. Riveting pin 81 can be hollow or solid. For example, the riveting pin can be cylindrical and hollow (and could be called a crimping pin).
    [039] The riveting pin 81 is located between the periphery of the blade receiving section 33 and the longitudinal and / or lateral sides 15, 17, 19, 21 of the housing 9. More precisely, each of the longitudinal sides 15, 17 has a first and a second end 85, 87, each of the side sides 19, 21 has a first and a second end 23, 25. Both the first and second side 19, 21 join the first and second ends 27, 29 of the first and second longitudinal sides 15, 17. Similarly, both the first and second longitudinal sides 15, 17 join the first and second ends 27, 29 of the first and second side sides 19, 21. The pin riveting 81 is located close to the first and / or second end 23, 25 of the first and / or the second longitudinal side 15, 17 and / or close to the end 27, 29 of the first and / or the second side side 19, 21.
    [040] As shown in Figures 1 and 2, the housing 9 preferably comprises a second riveting pin 83. For example, the first riveting pin 81 is located close to the first end 23 of the first longitudinal side 15, while the second pin 83 is located near the first end 23 of the second longitudinal side 17. For example, the first and second riveting pins 81, 83 are located on both sides of the cutting blade 35. The second riveting pin 83 is similar to the first riveting pin. riveting 81. However, in some embodiments, the second riveting pin 83 could be different. For example, the second riveting pin 83 could have another shape of the first riveting pin 81 or different dimensions. The material of the second riveting pin 83 may be different from the material of the first riveting pin 81.
    [041] In a mounted position of retainer 59 in housing 9, riveting pin 81, 83 cooperates with through hole 69, 71 of retainer 59. The shape of through hole 69, 71 of retainer 59 is complementary to the shape of the riveting 81, 83. As shown in Figures 6 and 7, the through hole 69, 71 has a circular cross-section. The diameter of the through hole 69, 71 is substantially the same as the diameter of the riveting pin 81, 83.
    [042] For example, as shown in Figure 2, in an assembled position, when the retainer 59 comprises two through holes 69, 71 and the housing 9 comprises two riveting pins 81, 83 (the riveting pins are located on the two sides of the cutting edge, for example), and each of the through holes 69, 71 of retainer 63 cooperates with a riveting pin 81, 83. The first through hole 69 is located towards the first free end 73 of retainer 59, while that the second through hole 71 is located towards the second free end 75 of retainer 59. The first and second through holes 69, 71 are adapted to cooperate with the first and second riveting pins 81, 83 in order to form a first and second rivet 61.
    [043] In the embodiment shown in Figures 5A and 5B, in an assembled position of the retainer 59, each leg 77, 79 is received in a recess 85 provided in the housing 9. The recess 85 extends from the upper side 11 of the housing 9. A recess 85 extends along the lateral geometric axis ZZ. The recess 85 is, for example, a blind hole. However, in other embodiments, the recess 85 may be a through hole (that is, an opening that passes through the housing, from the upper side of the housing to the lower side of the housing, and which is completely surrounded by the material, when viewed from the side or a cross-section).
    [044] The recess 85 can have different shapes. For example, recess 85 can be square, rectangular, circular, oval, U-shaped or L-shaped.
    [045] The shape of the recess 85 is preferably complementary to the shape of the leg 77, 79 of the retainer 59. Seen in a cross section, the shape of the leg 77, 79 of the retainer 59 can be rectangular. It thus cooperates with a recess in a rectangular shape 85. The shape of the leg 77, 79 of the retainer 59 can also be oval, seen in a cross-section, and then the leg can cooperate with an oval recess 81 The leg 77, 79, seen in a cross section, can be U-shaped, with a base that extends between two lateral parts. Leg 77, 79 can then be inserted into a recess 85, which is also U-shaped.
    [046] As shown in Figures 5A and 5B, the housing 9 comprises two recesses 85, each recess 85 being on both sides of the cutting edge. However, in some embodiment, retainer 59 could be provided with only one leg 77, 79 and housing 9 with only one recess 85.
    [047] Housing 9 may also comprise a third and fourth riveting pin 87, 89. The four riveting pins 81, 83, 87, 89 are preferably arranged, as shown in Figure 2, on the upper side 11, on the four corners of the housing 9, when the housing has a rectangular shape, for example. The four riveting pins 81, 83, 87, 89 are similar. The four riveting pins 81, 83, 87, 89 have the same orientation and project along the lateral geometric axis Z-Z. The four riveting pins 81, 83, 87, 89 have the same shape, that is, a tapered shape. However, in some embodiments, the four riveting pins 81, 83, 87, 89 may be different. For example, each riveting pin 81, 83, 87, 89 can have a different orientation, or a different shape, or can be of different materials.
    [048] In an alternative embodiment, as depicted in Figure 8, the riveting pin 81 is located on the first longitudinal side 15 of the housing 9. A second riveting pin 83 can be provided on the second longitudinal side 17. The riveting pin 81, 83 can project from the first / second longitudinal side 15, 17 along a direction that is orthogonal to the longitudinal geometric axis XX. For example, riveting pin 81, 83 can project along the transverse geometric axis Y-Y. The longitudinal side 15, 17 can have a width "ls" along the lateral geometric axis Z-Z. The riveting pin can be located in the central part, between the upper side 11 of the housing 9 and the lower side 13 of the housing 9.
    [049] In the embodiment shown in Figure 8, retainer 59 comprises a first leg 77, a second leg 79 and a retainer body 63 that extends between the first and second legs 77, 79. Retainer 59, in carrying out the Figure 8, has a shape that is similar to the shape of the retainer 59 depicted in Figures 5A, 5B and 7. However, the position of the through holes 69, 71 is different. Certainly, in order to cooperate with the riveting pins 81, 83 provided on the longitudinal sides 15, 17, the first through hole 69 and the second through hole 71 of retainer 59 in the embodiment of Figure 8, are provided in the first leg 77 and in second leg 79 of retainer 59. The first through hole 69 and / or the second through hole 71 are substantially in the central part of the first leg 77 and / or the second leg 79.
    [050] Figure 10 represents an embodiment of the through hole 69, 71 of the retainer 59 depicted in Figure 8. The through hole 69, 71 of the leg 77, 79 of the retainer 59 is at a non-zero distance from the free end of the leg 77, 79. The through hole 69, 71 is opened towards the free end of the leg 77, 79 of the retainer 59, in order to facilitate the assembly of the retainer 59 in the housing and the insertion of the riveting pin in the through hole 69, 71. In in other words, a channel 105 is provided from the free end of the retainer leg to the through hole.
    [051] Channel 105 communicates with through hole 69, 71 and extends to the free end of the leg 75, 77 of the retainer 59. The channel can be triangular in shape, with an enlarged opening towards the free end of the leg retainer and a small opening towards the through hole. Certainly, by mounting the retainer 59, the legs 77, 79 of the retainer 59 surround the housing 9 and, more precisely, surround the longitudinal sides 15, 17 of the housing, so that the first leg 77 of the retainer 59 surrounds the first side longitudinal 15, while the second leg 79 of the retainer surrounds the second longitudinal side 17.
    [052] As best shown in Figure 1 or 2, the cutting blades can be retained in the housing by two retainers 59, 91. The retainers 59, 91 are preferably the same, as shown in Figure 2 or in Figures 4, 5A, 5B . However, in some embodiments, the retainers 91 may be different. For example, the shape, size and / or materials of seals 59, 91 could be different. Each of the two retainers 59, 91 can have two through holes 69, 71, each of which cooperates with a riveting pin 81, 83 provided in housing 9. For example, the two through holes 69, 71 of the first retainer 59 cooperate with the first and second riveting pins 81, 83, while the two through holes 69, 71 of the second retainer 91 cooperate with the third and fourth riveting pins 87, 89. Thus, the two retainers 59, 91 are supplied in towards the first and second ends 37, 39 of the cutting blade 35. The retainers 59, 91 are located above the cutting edge 41, to retain the cutting blades 35 in the housing 9, and have a position that allows to avoid an important reduction of the area shaving / waxing. In addition, in one embodiment, a first retainer 59 could be flattened, as shown in Figure 6, while the second retainer 91 comprises two legs 77, 79 and a retainer body 63 that extends between the two legs, with the two legs are received in the recesses 85 of the housing 9.
    [053] The razor and shaving blade cartridge 1 may comprise a protection bar 93, which is provided in housing 9. The protection bar 93 is at the front of the cutting edge 41. The riveting pin 81, 83 may be adjacent to the protection bar 93.
    [054] The housing 9 may also comprise a rear cover 95, which may be provided with a shaving / shaving aid member 97. The shaving / shaving aid member 97 is at the rear of the cutting edge 41. O (s ) riveting pin (s) 81, 83 can be provided adjacent to the shaving / shaving aid member 97.
    [055] For example, in the embodiment depicted in Figures 1, 2, 4, 5A, 5B with four riveting pins 81, 83, 87, 89 and two retainers 59, 91, two riveting pins may be adjacent to the assist member in shaving / epilation 97, while two riveting pins are adjacent to the protection bar 93. In another embodiment with a housing 9 comprising two riveting pins 81, 83, the first riveting pin can be arranged adjacent to the protection bar 93, while the second riveting pin is disposed adjacent to the shaving / shaving aid member 97.
    [056] In one embodiment, a riveting pin could be located in the central part, between the first and the second longitudinal sides 15, 17. The riveting pin could then be adapted to cooperate with a through hole provided in the central part of the retainer body 63.
    [057] In carrying out Figure 8, the housing can be provided with four riveting pins. For example, two riveting pins 81, 87 are located on the first longitudinal side 15, and the two riveting pins 83, 89 are located on the second longitudinal side 17. The first riveting pin 81 on the first longitudinal side 15 and the second pin riveting pins 83 on the second longitudinal side 17 can be located towards the first longitudinal side 19, while the third riveting pin 87 on the first longitudinal side 15 and the fourth riveting pin 89 on the second longitudinal side 17 are located towards the second side side 21.
    [058] In order to mount the retainer 59, 91 in the housing 9 and to fix (secure without releasing) the retainer 59, 91 in the housing 9, the retainer 59, 91 will, in a first step, be placed in front of the upper side 11 of accommodation 9.
    [059] In the realization of Figure 8, mounting the retainer 59, 91, an operator (or an assembly machine) moves the retainer 59, 91 along the lateral geometric axis ZZ, in the direction of the lower side 13. The end free of the leg 77, 79 of the retainer 59, 91 travels along the longitudinal side 15, 17, up to the riveting pin 81, 83, 87, 89. The retainer 59, 91 is then moved further, so that the riveting pin is moved 81, 83, 87, 89 in channel 105 from the free end of the leg 75, 77 to the through hole 69, 71. When the riveting pin 81, 83, 87, 89 is received in the through hole 69, 71, the riveting pin 81, 83, 87, 89 is in its assembled position. In order to secure the retainer in the housing 9, the riveting pin is deformed to form a rivet, as shown in Figure 9.
    [060] The retainer 59, 91 is then mounted in the housing 9 by cooperating the riveting pin 81, 83, 87, 89 with the through hole 69, 71 of the retainer 59, 91. The inner surface 99 of the retainer body 63 is then opposite the upper side 11 of the housing 9. The outer surface 101 of the retainer body 63 is located opposite the inner surface 99. For example, slots can be provided in the housing to receive the retainer 59, 91, so that the retainer 59, 91 does not protrude from the upper side 11 of the housing 9. When the retainer 59, 91 is mounted in the housing 9, the riveting pin 81, 83, 87, 89 protrudes from the retainer 59, 91. More precisely, the length of the riveting pin 81, 83, 87, 89 along the lateral geometry axis ZZ, for the embodiments depicted in Figures 1, 2, 4, 5A and 5B, or along the transverse geometric axis YY for the realization depicted in Figure 8, it is greater than the thickness “ep” of the retainer 59, 91.
    [061] The retainer 59, 91 is then fixed to the housing 9, the end of the riveting pin 81, 83, 87, 89 deforming so that the dimension of the end of the riveting pin 81, 83, 87, 89 is larger than the size of the through hole 69, 71 and the retainer 59, 91 cannot move out of the housing 9. In other words, the free end 103 of the riveting pin 81, 83, 87, 89 is plastically deformed (or bent, or warped), so that the riveting pin 81, 83, 87, 89 deforms, in relation to its original shape on the outer surface 101 of retainer 59, 91. The deformation of the riveting pin 81, 83, 87, 89 allows retainer 59, 91 to be retained in place. The retainer 59, 91 is sandwiched between the deformed portion of the riveting pin 81, 83, 87, 89 and the housing 9. For example, the riveting pin can be hollow. In that case, the riveting can be likened to a bezel.
    [062] Deformation is performed by perforating the free end of the riveting pins 81, 83, 87, 89. Perforating the free end of the riveting pins 81, 83, 87, 89 introduces a plastic deformation of the riveting end.
    [063] For example, deformation could also be performed by applying an ultrasonic beam to the riveting pin 81, 83, 87, 89 and, more particularly, to the free end 103 of the riveting pin 81, 83, 87, 89. For example, a sonotrode (not shown) serves to transmit the ultrasonic beam. Applying an ultrasonic beam, a riveting melt deformation of the free end 103 of the riveting pin 81, 83, 87, 89 occurs. Rivet 61 could be obtained by methods other than ultrasonic riveting. The rivet 61 is then fixedly attached. The same sonotrode can perform several simultaneous rivets. For example, in the embodiment depicted in Figures 1, 2, 4, 5A, 5B with two retainers 59, 91 and two riveting pins 81, 83, 87, 89 per retainer 59, 91, the same sonotrode can perform the riveting of the four rivets 61 simultaneously.
    [064] After the plastic deformation of the riveting pin 81, 83, 87, 89, the rivet 61 is formed and the retainer 59, 91 is held in place by the rivet 61, as shown in Figures 3 and 9. For example, the housing 9 comprises recesses for receiving the rivet 61, so that the rivet 61 does not protrude from the housing 9. The rivet 61 can be aligned with the sides 15, 17, 11 of the housing 9. In the embodiments of Figures 1, 2, 3, 4, 5A, 5B, the rivet 61 can be aligned with the upper side 11 of the housing 9. In the embodiment of Figure 8, the rivet 61 can be aligned with the longitudinal side 15, 17 of the housing. The design of the housing 9 and, more precisely, the area receiving the rivet 61, can also be such that the rivet 61 is below the sides 15, 17, 11 of the housing 9.
    [065] The portions of retainer 59, 91 in front of the cutting blade retain the cutting blade 35. The retainer portion 59, 91 in front of the cutting blade 35 can touch the cutting blade 35, when the blades are in a resting position (that is, when no external force is applied to the razor cartridge for shaving and epilation). For example, retainer 59, 91 can comprise an aluminum alloy material. The blade 35 may comprise steel alloy material. The different materials between the blade and the retainer optimize the cathodic protection and the longevity of the blade.
    [066] In addition, retainer 59, 91 may comprise an aluminum alloy material. The cutting blade 35 may comprise steel alloy material. The different materials between the blade and the retainer optimize the cathodic protection and the cutting blade longevity.
