Definitions

  • This invention relates generally to shaving devices, and more specifically to replacement cartridges for razor assemblies. Background Information.
  • Modern safety razors typically include a disposable razor cartridge and a reusable handle, or a handle and cartridge combined into a unitary disposable.
  • Most razor cartridges include a frame, one or more razor blades, and a strip of shaving aid material attached to the frame.
  • a strip of shaving aid material typically includes one or more shaving aids (e.g., lubricating agents, drag reducing agents, depilatory agents, cleaning agents, medicinal agents, etc.) that enhance the shaving process.
  • shaving aids e.g., lubricating agents, drag reducing agents, depilatory agents, cleaning agents, medicinal agents, etc.
  • the comfort and performance provided by a particular safety razor are critical to the commercial success of the razor assembly. Improvements that benefit razor comfort, performance, and ease of use, however significant or subtle, can have a decided impact on the commercial success of a razor assembly.
  • a replacement cartridge for a razor assembly includes a shaving aid body that includes a contact surface and an aperture disposed in the contact surface that is sized to receive a razor cartridge.
  • the shaving aid body is coupled to a base that includes one or more features for attaching the replacement cartridge to the razor assembly.
  • the present invention replacement cartridge provides considerable utility when used with a razor assembly that allows the position of one or both of the blades in the razor cartridge and the contact surface of the shaving aid body to be adjusted relative to the other.
  • Examples of such razor assemblies are disclosed in United States Patent Application Serial Nos. 09/505,408 filed 2/16/2000; 60/405,185 filed 8/21/02, and (Docket No. 6579- 87-1 ), all of which are commonly assigned herewith and are hereby incorporated in their entirety by reference.
  • the present replacement cartridge is not limited to such applications, however.
  • An advantage of the present invention replacement cartridge is that a device is provided that is capable of dispensing a shaving aid material in a wet shaving environment.
  • a wet shaving environment can facilitate rather than impede the deposition of material from the shaving aid body of the present cartridge. Consequently, shaving within a wet shaving environment is not only possible, but practical as well.
  • Other advantages provided by the present replacement cartridge stem from the shaving aid body being a solid material that erodes during use, and distributes shaving aid material in the process.
  • An absorbent applicator that must be filled with liquid shaving aid material prior to use, as is known in the prior art, requires additional effort by the user. It also requires that the user utilize an appropriate liquid. An inappropriate liquid accidentally loaded into the absorbent applicator could have undesirable results.
  • An absorbent applicator in a wet shaving environment also absorbs water, and thereby likely dilutes and/or otherwise negatively effects the application of the liquid shaving aid material loaded into the applicator. Finally, an absorbent applicator consisting of a porous absorbent material will likely have an undesirable high running friction coefficient that produces unwanted drag.
  • the present invention solid shaving aid body in contrast, does not need to be filled before each use, provides an assurance regarding the shaving aid material, performs well in a wet shaving environment, and provides a desirable slippery surface, all of which increase the user's shave comfort.
  • the present invention replacement cartridge provides considerable utility when used with a razor assembly that allows the position of one or both of the blades in the razor cartridge and the contact surface of the shaving aid body to be adjusted relative to the other.
  • the contact surface of the solid shaving aid body provides a surface that can be located relative to the blades in the razor cartridge.
  • the contact surface of the solid shaving aid body also provides a guide for the surface being shaved.
  • FIG. 1 is a perspective view of a replacement cartridge including a present invention shaving aid cartridge.
  • FIG. 2 is a diagrammatic cross-sectional view of a shaving aid cartridge showing the base embedded within the shaving aid body.
  • FIG.3 is a diagrammatic cross-sectional view of a shaving aid cartridge showing the base attached to a surface of the shaving aid body.
  • FIG.4 is a perspective view of the shaving aid cartridge of FIG. 1 with the razor cartridge removed.
  • FIG. 5 is a top perspective view of a base embodiment.
  • FIG. 6 is a bottom perspective view of a base embodiment.
  • FIG. 7 is a bottom perspective view of a second base embodiment.
  • FIG. 8 is a bottom perspective view of a third base embodiment.
  • FIG. 9 is a perspective view of an embodiment of the present shaving aid cartridge.
  • a replacement cartridge 10 for use with a razor assembly includes a shaving aid body 12.
  • the shaving aid body 12 is coupled to a base 14.
  • the shaving aid body 12 has a forward portion 16, an aft portion 18, a first lateral portion 20, a second lateral portion 22, all of which are disposed around a centrally located aperture 24, which is sized to receive a razor cartridge 26.
  • the aperture 24 may be described as having a centerline 28 (see FIGS. 2 and 3).
  • the shaving aid body portions 16,18,20,22 extend from a contact surface 30 to a base surface 32.
  • the aperture 24 is disposed in the contact surface 30.
  • the aperture 24 may alternatively be described as being formed by a plurality of the shaving aid portions 16,18,20,22 positioned relative to one another in a manner that creates the centrally located aperture 24.
  • the shaving aid body 12 is one piece, having a generally oval shape.
  • the shaving aid body 12 may assume an alternative shape and/or may include multiple pieces; e.g., the above-described portions of the shaving aid body 12 may be separate from one another.
  • the shaving aid body 12 may be some combination of less than all of the portions. For example, in some applications it may be desirable to have a shaving aid body 12 that includes only a pair of lateral portions 20,22 and a forward portion 22. In other applications it may be desirable to have only a single forward portion 22.
  • the aperture 24 extends between the contact surface 30 and the base surface 32. In alternative embodiments, however, the aperture 24 may not extend between the surfaces 30,32. In such instances, a second aperture 34 (example shown in phantom in FIG.3) may be included, extending between the base surface 32 and the aperture 24.
  • the second aperture 34 may have a different cross-sectional geometry than the aperture 24, or the same. If the second aperture 34 has the same cross-sectional geometry as the aperture 24, the aperture 24 may be described as extending between the contact surface 30 and the base surface 32.
  • the contact surface 30 skewed at a non- perpendicular angle relative to the aperture centerline 28.
  • the skew angle facilitates recognition by the user of the direction the razor assembly is intended to be stroked.
  • the magnitude of the skew angle is application dependent based upon the relationship of the contact surface 30 of the shaving aid body 12 and the position of the razor cartridge 12.
  • the shaving aid body 12 is an erodable solid body consisting of a shaving aid material that is selected to suit the application at hand.
  • a soap-type shaving aid material is particularly well suited for wet shaving applications, but other shaving aid materials (e.g., lubricating agents, drag reducing agents, depilatory agents, cleaning agents, medicinal agents, sensory agents, skin stimulation agents, etc.) can be used alternatively, or some combination thereof.
  • the bottom surface 32 of the shaving aid body 12 may include features (e.g., apertures) to facilitate the attachment of the shaving aid body 12 to the razor assembly.
  • the base 14 includes a first surface 36, a second surface 38, and one or more features 40 for attaching the replacement cartridge 10 to the razor assembly.
  • the features 40 are preferably mechanical-type features such as tabs that extend outwardly from the second surface 38.
  • a variety of different feature 40 configurations can be used.
  • FIG.6 shows a plurality of notched tabs 42 extending out from the second surface 38.
  • FIG.7 shows a plurality of apertured tabs 44 extending out from the second surface 38.
  • FIG.8 shows a combination of slotted tabs 46 and apertured tabs 44.
  • the exact configuration of features 40 is selected to cooperate with the counterpart attachment mechanism of the razor assembly. Hence, the features 40 shown in FIGS.
  • the features 40 are asymmetrically positioned on the base 14 in such a way as to provide a single orientation for proper installation of the replacement cartridge 10 on the razor assembly.
  • the base 14 further includes an aperture 50 that extends between the first surface 36 and second surface 38.
  • the aperture 50 permits one or more elements (not shown) to extend between a razor cartridge disposed within the aperture 24 of the shaving aid body 12 and a mechanism attached to the razor assembly.
  • the aperture 50 is aligned with and has an axial cross-section similar to, or the same as, the aperture 24 within the shaving aid body 12. In this configuration, the razor cartridge 26 can be received within the aperture 50 of the base 14.
  • the embodiment shown in FIG.9 in contrast, includes a base 14 without an aperture 50 coupled with a two piece shaving aid body 12.
  • the base may include features for guiding an element within the aperture 50.
  • the features 40 include slots 46 for cooperation with guide surfaces attached to an element (not shown) that is received within the aperture to guide the element within the aperture 50.
  • Other guide arrangements may be used alternatively.
  • the base 14 further include a plurality of tabs 52 that extend out from the base 14 in a lateral direction.
  • the tabs 52 are used to locate the replacement cartridge 10 within packaging.
  • Some embodiments of the base also include a rail 54 (see FIG.5) attached to the first surface 36 of the base 14.
  • the rail 54 facilitates high speed feeding of the base 14 through automated forming and assembly equipment and thereby aids the manufacturing process. Other features that facilitate manufacturing and/or handling of the replacement cartridge 10 may be included alternatively, or in combination therewith.
  • the base 14 is integrally formed with the shaving aid body 12.
  • integrally formed refers to a base 14 that consists of one or more shaving aid materials or constituents thereof and is at least partially formed at the same time as the shaving aid body 12.
  • the portion of the shaving aid material that forms the base 14 either initially has, or is processed to have, sufficient mechanical strength to be operable to enable attachment of the replacement cartridge 10 to the razor assembly.
  • the appropriate process e.g., curing, compression, etc.
  • the base 14 is a separate member that is partially or completely embedded within the shaving aid body 12 when the shaving aid body 12 is formed.
  • Mechanical features other than those used to directly or indirectly attach the replacement cartridge 10 to the razor assembly are used to secure the shaving aid body 12 and base 14 together.
  • the apertures 56 disposed in, and the flanges 58 attached to, the base 14 create passages and voids in which a shaving aid material in liquid form can travel and solidify during formation. Once solidified, the mechanical strength of the shaving aid material (aided by the geometry created within the aforesaid passages and voids) is sufficient to keep the shaving aid body 12 and the embedded base 14 together.
  • the base 14 is attached to, rather than being embedded in, the shaving aid body 12.
  • the attachment can be accomplished by a variety of methods, including but not limited to mechanical means (e.g., screws, rivets, pins, barbs, etc.), adhesive (e.g., glue, etc.), or bonding (e.g., welding, etc.).
