Description

BACKGROUND

1. Field

The following description relates to shaving razors. A shaving razor may include a head with one or more blades and a retainer configured to retain components of the shaving head. For example, a shaving razor may include a head with one or more blades which are secured in the head by a retainer bar which is received by the housing of the head.

2. Description of Related Art

Shaving razors include shaving heads which contain components such as shaving blades, lubrication strips, guard bars, covers, and trimming blades. The components in conventional shaving heads would be individually and separately retained within the shaving head. As such, the components would each have separate retaining means; for example, traditional clips may be utilized for each component. However, bending traditional clip legs at multiple locations of the cartridge provides for difficulties in manufacturing while also providing multiple locations for retaining the components and managing the tolerances that are applied.

During the manufacturing process of conventional shaving heads, the clips may encounter buckling as a result of force that is applied during installation of the clips. As a result of a bending force exerted on the clips, the clips have a tendency to buckle upwards. Consequently, blade exposures may be unstable throughout the razor cartridge and may vary significantly from intended blade exposure values. Also, during manufacturing process, clips may fail to be properly installed in a razor housing, which requires additional attention and labor to ensure that the clips are properly installed in the housing.

According to some aspects, FIGS. 1-5 details a shaving razor 10 which may include a handle 12 coupled with a shaving head 100. The handle 12 may include a proximal end 13 and a distal end 14 and may extend in a handle direction between the proximal end 13 and the distal end 14. The shaving head 100 may be coupled with the distal end 14 of the handle 12. The shaving head 100 may be removably coupled with the handle 12, for example, by a lock and release mechanism. According to other aspects, the shaving head 100 may be fixedly coupled with the handle 12 such that the shaving head 100 is not configured to be removably coupled with or selectively separated from the handle 12. The shaving head 100 may be operable to pivot relative to the handle 12. According to some aspects, the handle 12 may be secured to the shaving head 100 in a fixed relationship such that shaving head 100 is not operable to pivot relative to the handle 12. The handle 12 may be any suitable shape to allow a user to securely grip the handle 12. The handle 12 may include one continuous curve or include one straight portion or several curved and/or straight portions extending along an entirety of or a substantial portion of the handle 12.

According to further aspects, the shaving head 100 may include a housing 101. The housing 101 may extend along a longitudinal axis X-X. The housing 101 may include a substantially rectangular shape but may be any suitable shape such as ovoid or circular without deviating from the scope of the present disclosure. The shaving head 100 and the housing 101 may include a top side 102 and a bottom side 104 opposite the top side 102. The bottom side 104 may be proximate to the handle 12, and the top side 102 may include at least one skin contacting area. The housing 101 may further include first and second longitudinal walls 106, 108. Each of the first and second longitudinal walls 106, 108 may extend longitudinally along the longitudinal axis X-X between the top and bottom sides 102, 104 and in a direction Z of the housing 101. The first and second longitudinal walls 106, 108 may extend substantially parallel to each other. The shaving head 100 and the housing 101 may include first and second side walls 110, 112 that may extend substantially parallel to each other and between the first and second longitudinal walls 106, 108 along a direction Y of the housing 101. The first and second side walls 110, 112 may also extend between the top and bottom sides 102, 104 along the direction Z of the housing 101. The housing 101 may be further be made of, for example, plastic, metal, another suitable material, or any combination thereof.

The shaving head 100 may further include a plurality of components 113 which may assist, and which may contribute to the shaving experience of the user. One of the components 113 may be a plurality of blades 116 disposed and retained within the housing 101. The blades 116 may extend along the longitudinal axis X-X. According to some aspects, the shaving head 100 can include, for example, one, two, three, four, or more of the blades 116. The blades 116 may be movably disposed or freely mounted, in the housing 101. For example, the blades 116 may be coupled with elastic fingers which extend from the housing 101. According to other aspects, the blades 116 may be fixedly disposed in housing 101.

According to some aspects, the components 113 of the shaving head 100 may also include, for example, a cap 114, a lubricating strip 115, and a guard bar 118 included on and/or retained within the shaving head 100. The cap 114 may be coupled with the first longitudinal wall 106. The lubricating strip 115 may be disposed on the top side 102 of the cap 114 to deliver a friction reduction effect, an anti-irritation effect, and/or provide lubrication after shaving. The guard bar 118 may be coupled with the second longitudinal wall 108 opposite the cap 114 to stretch the skin during shaving or dispense the forces applied to the skin, thereby causing the shaving head 100 to glide across the skin while providing a closer shave. The cap 114, the lubricating strip 115, and the guard bar 118 may each extend along the longitudinal axis X-X. According to further aspects, additional components, such as for example, a cover and/or one or more trimming blades, may also be included on and retained within the shaving head 100.

The components 113 may be retained within or on the shaving head 100 by retainers 150. For example, the retainers 150 may be operable to retain the blades 116, the cap 114, the lubricating strip 115, and the guard bar 118 on or within the shaving head 100. The retainers 150 may retain the components 113 by securely abutting and partially covering (i) a portion of the components 113, such as for example, the lateral sides or sides along the direction X of the components 113, and (ii) the side walls 110, 112 of the housing 101. The retainers 150 may be operable to secure one or more other components within or on the shaving head 100. According to other aspects, any one or more of the components 113 may be secured to the shaving head 100 without the retainers 150, such as for example, by any other well-known securing means.

According to some aspects, as shown in FIGS. 2A and 2B, the retainer 150 may include a body 152 and ears 154 on either side of the body 152. According to other aspects, the retainer 150 may have one ear without deviating from the scope of the present disclosure. The retainer 150 may be a bar which is coupled with the housing 101 such that the body 152 of the retainer 150 may be held above and covers a portion of the components 113, including the blades 116. The retainer 150 may be made, for example, of a metal, such as aluminum, but the retainer 150, according to some aspects, may also be made of any suitable material, so long as the material is sufficient to couple with the housing 101 while securely retaining the components 113 in the housing 101. The housing 101 may include a cavity 160 formed therein to receive the retainer 150. The cavity 160 may include openings 162 to receive and retain the ears 154 of the retainer 150. The retainer 150 may be held in place between the top side 102 of the housing 101 and the blades 116, or one or more of the components 113. The cavity 160 may be sized and shaped to correspond with the retainer 150. According to some aspects, the cavity 160 may be as large as desired, so long as the retainer 150 may be received, as the retainer 150 is secured by being between the top side 102 of the housing 101 and the components 113. According to other aspects, the openings 162 may be through holes. As such, the ears 154 may abut the walls of the openings 162thereby securing the retainer 150 in the housing 101. The position of the retainer 150 may correlate to the exposure of the blades 116. As such, the position of the retainer 150 may be adjusted to provide the desired exposure of the blades 116.

According to aspects, as shown in FIGS. 3 and 4, the retainer 150 may be substantially cylindrical, but may also be any suitable shape such as rectangular without deviating from the scope of the present disclosure. The retainer 150 being the shape of a bar may provide for easier manufacturing due to the shape being easily extruded. Also, the retainer 150 may easily be made accurately straight. Further, the stiffness of the shape provides sufficient strength to hold the components 113 within the housing 101. The body 152 of the retainer 150 may have a width 152A of, for example, about 1.0 mm. The width 152A of the retainer 150 may be determined by the diameter of the retainer 150. According to some aspects, the body 152 of the retainer 150 may have a width 152A inclusive of, about, and/or between, for example, 0.5 mm and 1.0 mm. The length 152B of the body 152 of the retainer 150 may be about 9.36 mm, for example. However, according to other aspects, the length 152B of the body 152 of the retainer 150 may be as long as desired or necessary to adequately secure the desired components 113. The ears 154 of the retainer 150 extend from the sides of the body 152. The ears 154 may be substantially cylindrical but may also be any suitable shape such as, for example, rectangular. The ears 154 may be substantially the same shape as the body 152 of the retainer 150, but may also be a different shape than the body 152. For example, the body 152 may be cylindrical while the ears 154 may be rectangular. The ears 154 of the retainer 150 may have a width 154A of about 0.5 mm. However, according to some aspects, the width 154A of the ears 154 may vary as desired. The length 154B of the ears 154 may be about half of the diameter or width 152A of the body 152. As such, the length 154B of the ears 152 may be, for example, about 0.5 mm. Additionally, the length 154B of the ears 154 may also vary as desired.

The ears 154 may be configured to be compressed into the body 152 of the retainer 150. As such, the ears 154 may be received by a recess 1540 that extends into the sides of the body 152. A spring 1542 may also be received in the recess 1540 such that the ears 154 may abut the spring 1542. When the ears 154 are compressed by a force into the body 152, the ears 154 may abut and compress the spring 1542. As such, when the compression force is removed, the spring 1540 may decompress, forcing the ears 154 out from the body 152 of the retainer 150.

According to some aspects, to install the retainer 150, the ears 154 of the retainer 150 may be compressed into the body 152. The retainer 150, with the ears 154 compressed into the body 152, may be inserted into the cavity 160. The compression force may be removed from the ears 154 such that the ears 154 may extend from the body 152. The ears 154 may then abut the housing 101 above, while the body 152 may abut and secure the components 113 below. Between the housing 101 above and the components 113 below, the retainer 150 may be secured in and coupled with the housing 101.

The retainer 150, according to further aspects, as shown in FIG. 5, may include a cover 1010 coupled to the housing 101. The cover may be provided to hide the retainer 150. The cover 1010 may be snap fitted onto the housing 101. According to some aspects, the cover 1010 may be press fitted, or any other suitable method of coupling the cover 1010 to the housing 101. The cover 1010 may provide aesthetic and safety benefits. For example, the cover 1010 may protect the skin for nicks and cuts by the exposed ends of the blades 116.

According to further aspects, as shown in FIG. 6, disclosure a shaving head 200 may include a plurality of components 213 which may assist, and which may contribute to the shaving experience of the user. One of the components 213 may be a plurality of blades 216 disposed and retained within the housing 201. The blades 216 may extend along the longitudinal axis X-X. The shaving head 200 may include, for example, one, two, three, four, or more of the blades 216. The blades 216 may be movably disposed or freely mounted, in the housing 201. For example, the blades 216 may be coupled with elastic fingers which extend from the housing 201. According to other aspects, the blades 216 may be fixedly disposed in the housing 201.

The components 213 of the shaving head 200 may also include a cap 214, a lubricating strip 215, and a guard bar 218 included on and/or retained within the shaving head 200. Additional components, such as for example, a cover and/or one or more trimming blades, may also be included on and retained within the shaving head 100.

According to some aspects, a plurality of the components 213 may be retained within the shaving head 200 by retainers 250. For example, the retainers 250 may be operable to retain the blades 216, the cap 214, the lubricating strip 215, and the guard bar 218 within the shaving head 200. The retainers 250 may be installed in each of the two side walls 212 (the other side wall 210 not shown in the partial view of FIG. 7) of the housing 201. The retainers 250 may be installed in other walls or only one of the side walls of the housing 201. The retainers 250 may retain the components 213 by securely abutting and partially covering (i) a portion of the components 213, such as for example, the lateral sides or sides along the direction X of the components 213, and (ii) the side walls 212 (the other side wall 210 not shown in the partial view of FIG. 7). The retainers 250 may be operable to secure one or more other components 213 within or on the shaving head 200 without deviating from the scope of the present disclosure. According to further aspects, any one or more of the components 213 may be secured to the shaving head 200 without the retainers 250, such as for example, by other well-known securing means.

According to some aspects, the retainer 250, in FIGS. 6 and 7, may be a bar with a substantially homogenous shape. The retainer 250 may have a shape that is substantially cylindrical, but may also be any suitable shape such as, for example, rectangular or any other shape. The retainer 250 being the shape of a bar may provide for easier manufacturing due to the shape being easily extruded. For example, if extruded, the shape of the retainer may follow the profile of the die which could be a circle, oval, half circle, polygon or amorphous shaped. If the retainer has a flat surface (for example, a half circle shape), the retainer may have a higher surface contact with each component or blade edge. Also, the retainer 250 may be easily made accurately straight. Further, the stiffness of the shape may provide sufficient strength to hold the components 213 within the housing 201. The retainer 250 may be made, for example, of a metal, such as aluminum. However, according to other aspects, the retainer 250 may be made of any suitable material without deviating from the scope of the present disclosure, so long as the material is sufficient to couple with the housing 201 while securely retaining the components 213 in the housing 201. The retainer 250 may have a width 250A of, for example, about 0.5 mm. The width 250A of the retainer 250 may be determined by the diameter of the retainer 250. According to further aspects, the retainer 250 may have a width 250A inclusive of, about, and/or between, for example, 0.5 mm and 1.0 mm. The length 250B of the retainer 250 may be about 9.36 mm. According to some aspects, the length 250B of the retainer 250 may be as long as desired or necessary to adequately secure the desired components 213.

As illustrated in FIGS. 6, 8A, and 8B, the housing 201 may include two receptacles 260 to receive and secure the retainer 250. The figures show only one side of the shaving head 200, but the same or substantially similar configuration may be utilized on the other side of the shaving head 200. While two receptacles 260 may be detailed, less or more receptacles 260 may be utilized to couple the retainer 250 with the housing 201. The receptacles 260 may be located on each side of the blades 216, along a Y direction. According to some aspects, the receptacles 260 may be located on each side and/or in between the blades 216 or any other components 213. The retainer 250, may also be secured and held by the receptacles 260, and may sit above and cover a portion of the components 213 to secure the components 213 within the housing 201. As such, if the components 213 may move upwards, the bottom of the retainer 250 may then abut the top of the portion of the components 213, thereby retaining the components 213 in the housing 201.

The receptacles 260 may include an opening 262. A space 264 may be formed at an entrance to the opening 262. The space 264 may be formed by flanges 263 positioned on either side thereof. The opening 262 may receive the retainer 250 therein. The housing 201 may be made of plastic; and may have a relative elasticity in comparison to the retainer 250. The retainer 250 may be snap fitted and may enter the opening 262. As such, the plastic material of the flanges 263 may have an elasticity which may allow the flanges 263 to expand to allow the retainer 250 to be received therein. When the retainer 250 is received by the opening 262, the flanges 263 may return to their normal shape, holding the retainer 250 tightly within the opening 262. The opening 262 may have a diameter 262A which may be, for example, about 0.05 mm to 0.15 mm smaller than the width 250A, or diameter, of the retainer 250. For example, if the width 250A of the retainer 250 may be about 0.5 mm, the diameter 262A of the opening 262 would be about 0.45 mm. However, according to some aspects, the diameter 262A of the opening 262 may be inclusive of, about, and/or between, for example, 0.45 mm and 0.35 mm. The size 264A of the space 264 of the opening 262 may be slightly narrower than the diameter 262A of the opening 262 to secure the retainer 250 in the opening 262. For example, if the opening 262 may have a diameter 262A of, for example, 0.45 mm, and the size 264A of the space 264 of the opening 262 may be, for example, about 0.43 mm. The center of the opening 262 may be a distance 20 of at least 0.88 mm, for example, from the top of the flanges 263 such that the plastic does not break during assembly or usage.

The shaving head 200 may also include a cover (not labeled in 6, 8A, and 8B) coupled to the housing 201. The cover may be provided to hide the retainer 250. The cover may be snap fitted onto the housing 201. According to some aspects, the cover may be press fitted, or any other suitable method of coupling the cover to the housing 201. The cover may provide aesthetic and safety benefits, such as for example, the cover may protect the skin for nicks and cuts by the exposed ends of the blades 216.

According to further aspects, FIGS. 9A and 9B detail a shaving head 300including a plurality of components 313 which may also assist and contribute to the shaving experience of the user. One of the components 313 may be a plurality of blades (not labeled) disposed and retained within the housing 301. The blades may extend along the longitudinal axis X-X. The shaving head 300 may include, for example, one, two, three, four, or more of the blades without deviating from the scope of the present disclosure. The blades may be movably disposed or freely mounted, in the housing 301. For example, the blades may be coupled with elastic fingers which may extend from the housing 301. According to some aspects, the blades may be fixedly disposed in the housing 301.
