Shave Cream Applicator
An applicator for shaving cream and method of applying shaving cream comprising a handle, and a flexible blade of closed cell EVA foam. The blade has opposing faces tapered from thickest at the handle to thinnest at the tip of the blade. Each face comprises a “U” shaped valley with two arcuate through-hole slots for the transfer of shaving cream from one face to the other, such slots being oriented substantially perpendicular to the lengthwise axis of the applicator, a plurality of generally horizontal ribs for holding the shaving cream, a plurality of generally vertical ribs to assist in keeping the blade mostly flat, and a plurality of generally vertical through-holes along a “U” shaped side wall for the transfer of shaving cream between faces. In use, excess shaving cream is transferred from one face to the opposing face via through-holes in the blade for use with the opposing face.
The invention relates generally to shaving, and more specifically, to apparatus and methods for spreading shaving cream over a person's skin.
BACKGROUND OF THE INVENTIONNowadays aerosol shaving cream is commonly dispensed from a canister onto a person's fingers and then spread over the person's face or other skin surfaces to be shaved. Shaving cream tends to cling to the person's fingers which make it necessary for the person to wash his or her hands before handling a razor. If a second application of shaving cream is required for a closer shave, these steps must be repeated. A traditional bristled shaving brush may be used as an applicator, eliminating the need to wash the person's hands before handling the razor. However, such a brush is more suited to creating lather through a circular motion against soap than to applying shaving cream dispensed from a canister. Also, a brush must be thoroughly washed after use as shaving cream remaining in the brush tends to make the bristles stick to one another, leaving the brush stiff and difficult to use.
Canadian Patent No. 1,288,391 issued to Ray McLennan on Sep. 3, 1991 describes a shaving cream applicator with a hollow wedge-shaped spreader. The spreader is formed of a plastic foam and comprises fine passageways that extend between the hollow interior and the exterior of the spreader. Shaving cream is delivered under pressure to the interior and is ultimately discharged through the passageways onto the exterior of the spreader. It is not apparent how readily shaving cream can be cleaned from the passageways after use, and the applicator would appear susceptible to clogging if residual shaving cream dries in the passageways.
BRIEF SUMMARY OF THE INVENTIONThe present invention provides a novel shaving cream applicator and associated methods of applying shaving cream that avoid shortcomings associated with the prior practices identified above.
In one aspect, the invention provides an applicator for applying shaving cream to a person's skin. The applicator comprises a handle and a flexible blade attached to the handle. The blade has a pair of opposing faces and a set of elongate slot through-holes that extend between the faces, the slots being oriented substantially perpendicular to the lengthwise axis of the applicator. Such through-holes allow better transfer of excess shaving cream from one face to the other face, as explained more fully below.
In another aspect, the invention provides an applicator for applying shaving cream to a person's skin. The applicator comprises a handle and a flexible blade attached to the handle. The blade has a pair opposing faces and a set of through-holes that extend between the faces for the transfer of excess shaving cream from one face to the other face. The applicator additionally provides an additional through-hole in the blade proximate the top of the handle which acts as a trap for excess shaving cream to reduce or prevent the flow of shaving cream along the blade and onto the handle which may otherwise soil the handle making the handle slippery and difficult to use. The trap also serves to direct the bending of the blade away from the top of the handle and across the trap causing the blade to bend further away from the handle allowing better access of the applicator surface to a person's face.
In another aspect the invention provides for an applicator having a handle and a flexible blade attached to the handle, the blade having a pair of opposing faces. In this aspect each of the two opposing faces are provided with a valley having at least one valley wall, a valley base, and a set of through-holes that extend between the valley base of each face for the transfer of shaving cream between the valley base of each of the two faces.
In another aspect, the invention provides a method of using such an applicator to apply shaving cream to a person's skin. The method comprises applying shaving cream to one face of the applicator blade. The person then positions the applicator by means of its handle so as to contact the shaving cream with the person's skin and simultaneously displaces the applicator to spread the shaving cream. The through-holes reduce or prevent the shaving cream from sliding or flowing freely along the blade when oriented substantially vertically or when the applicator is actually used to spread shaving cream over the skin. Instead, the through-holes tend to trap shaving cream, and excess shaving cream eventually passes through the holes and accumulates on the opposite face of the blade. The applicator may then be manipulated by means of its handle to contact the shaving cream that has accumulated on the opposite face of the blade with the person's skin, and to simultaneously displace the applicator thereby spreading the excess shaving cream. These steps may be repeated to spread a desired quantity of shaving cream but typically the opposing faces will be interchanged just a single time.
Other aspects of the invention will be apparent from the description of the embodiments below and as defined in the appended claims. For the purposes of this specification, the term “shaving cream” should be understood as encompassing shaving foams, shaving gels and other compositions commonly dispensed from a canister and adapted to lubricate the skin to allow smoother shaving. A “through-hole” should be understood as a hole extending fully through opposing surfaces of an object and accessed from either surface of the object. The term “set” should be understood as identifying a non-empty set; that is, a set comprising one or more members.
The invention will be better understood with reference to drawings illustrating various embodiments of the invention, in which:
In the drawings, applicator components with the same general function or structure in all three embodiments are indicated with the same reference numeral.
DESCRIPTION OF EMBODIMENTSReference is made to
The blade 11 has a central lengthwise axis 13 which is shown vertical in the drawings and which incidentally constitutes the central lengthwise axis 13 of the applicator 10 itself. In the orientation of
The blade 11 has a pair of opposing faces 18, 19 and a set of through-holes 20, 21 (two in this embodiment) that extend between the opposing faces 18, 19. Each of the through-holes 20, 21 is an elongate arcuate slot oriented substantially perpendicular to the lengthwise axis 13 of the blade 11, and is substantially horizontal when viewed in the vertical orientation of the applicator 10 shown in
Reference is made to
The blade 11 is may be formed of flexible, closed-cell Ethylene Vinyl Acetate (EVA) foam injected into a mold of appropriate shape. The closed-cell construction ensures that debris is not readily trapped and makes washing of the applicator 10 very simple. Also as there is almost no water absorption by the closed cell material, there is little or no moisture retention, thus reducing or preventing bacterial growth and increasing hygiene. Blade 11 may also be made from closed cell plastic foam, thermo plastic elastomers, thermo plastic rubber, silicone PVC, neoprene rubber, silicone, foamed rubber, foamed plastic, or other suitable material. Without restricting the generality of the foregoing, these materials may also be used for blades 11 and 58 of fourth applicator 30 and fifth applicator 50 respectively.

Reference is made to
Another difference in fourth applicator 30 relative to first applicator 10, second applicator 22 and third applicator 23 is that an alternate embodiment for the construction of handle 12 is provided. Handle 12 consists of a front handle portion 34 and a back handle portion 35, and a bottom handle portion 37. In assembled condition, front handle portion 34 and back handle portion 35 are joined along handle seam 36.
The upper end of handle 12 contains a blade cavity 41 for securing mounting section 43 of blade 11. The inside sides of blade cavity 41 comprises one or more teeth 40 for better securing faces 18, 19 of mounting section 43 of blade 11 within blade cavity 41, when handle portions 34, 35, are in an assembled condition. In one embodiment, the one or more teeth 40 are arranged substantially perpendicular to the lengthwise axis 13 of blade 11, and comprises a plurality of single teeth 40 which run substantially the entire width of opposing faces 18, 19, of mounting section 43 of blade 11.
The blade 11 of fourth applicator 30 also comprises at least one and preferably two mounting holes 38 through mounting section 43 of blade 11 for insertion into blade cavity 41 of handle 12 to better secure blade 11. Back handle portion 35 comprises an inner mounting post 39 for each of mounting holes 38 in blade 11. Front handle portion 34 comprises an outer mounting post 42 for each of mounting holes 38. The outside diameter of outer mounting posts 42 is substantially the same diameter as mounting holes 38. Outer mounting posts 42 are positioned in mounting holes 38 of blade 11 in a substantially friction fit. Handle portions 34, 35, are pushed together such that inner mounting posts 39 nest inside outer mounting posts 42 through mounting holes 38, thus securely holding mounting section 43 of blade 11 in blade cavity 41 of handle 12. Handle portions 34, 35, may be held together by any means known in the art, including snap fittings, gluing, welding, screwing, taping, or other known fastenings means.
Handle bottom 37 may be a separate piece from handle portions 34, 35, and may be held in place by similar means. Alternatively, handle bottom 37 may be integral to one of handle portions 34, 35, or may be divided in 2 and be integral to both handle portions 34, 35. Handle 12 comprises handle grips 32, which further comprise ridges 33.
Reference is made to
Lengthwise tapered blade 58 tapers from a maximum thickness at the bottom of blade 58, where same meets the top of handle 12, to a minimum thickness at the tip 27 of tapered blade 58 tapered. Blade 58 comprises a generally “U”shaped valley 56 defining a “U” shaped valley wall 52. Wall sides 57 of the “U”shaped valley wall sides 57 taper outwardly from lengthwise axis 13 along opposing faces, 18, 19 from narrow lower end portion 14 of blade 58 to broad upper end portion 15 of blade 58. Valley 56 is bounded by wall 52, valley 56 having valley base 59. Valley base 59 on each of faces 18, 19 together may be substantially of equal thickness except for generally horizontal ribs 55 and generally vertical ribs 54. Vertical ribs 54 help to keep valley base 59 in a substantially flat orientation for applying shaving cream to a person's face, and help to concentrate bending of blade 58 across generally gibbous through-hole 51. Generally gibbous through-hole 51 performs substantially the same function as generally triangular through-hole 31 of fourth applicator 30. Bend edges 48 of fifth applicator 50 tend to bend most close to where the width of generally gibbous through-hole 51 is widest perpendicularly to lengthwise axis 13 of blade 58.
Generally vertical ribs 54 may be of other shapes and configurations, but vertical ribs direct, and allow, for shaving cream to flow lengthwise off ribs 54 along valley base 59 towards the tip 27 of blade 58 with the least resistance.
Valley base 59 may comprises a plurality of generally horizontal ribs 55 oriented substantially perpendicular to the lengthwise axis 13 of blade 58. Generally horizontal ribs 55 may be elongate arcuate ribs generally concentric with one another and concentric with through-holes 20, 21. The length of each elongate arcuate rib 55 may increase with distance from the handle 12.
Generally horizontal ribs 55 across valley bases 59 of faces 18, 19, provides grip to the shaving cream to assist in depositing shaving cream on a person's face, thus reducing the drifting of shaving cream through through-holes 20, 21 and towards to the tip 27 and side edges 16 of blade 58.
Fifth applicator 50 also comprises a plurality of generally vertical through-holes 53 along wall sides 57. Generally vertical through-holes 53 may be angled outwardly along wall sides 57. Although generally vertical through-holes 53 need not be strictly vertical, nor need they abut wall sides 57, such generally vertical through-holes are generally tapered outwardly to follow the contour of wall sides 57, in order to catch excess shaving cream before it overflows wall 52. Generally vertical through-holes 53 through valleys 59 are located along wall sides 57 between through-holes 20, 21, and along wall sides 57, between the tip 27 of blade 58 and through-hole 20.
Through-holes 20, 21 and 53 may also have rounded inside edges for allowing excess shaving foam to pass through blade 58 with as little resistance as possible, and with as little irritation to the face or other skin surface of a user. Similarly side edge 16 may be rounded to allow for easier movement with potentially less resistance along the face or other skin surface of a user, especially movements at least partially lateral in nature, or substantially circular in nature. The tops of the junctions between faces 18, 19 and valley walls 52 and the junctions between valley walls 52 and valley bases 59 are also rounded to reduce friction and irritation and to aid in cleaning of the applicator.
It will be appreciated that particular applicator embodiments have been illustrated to exemplify the invention and that modifications and improvements may be made to those embodiments without departing from the scope of the appended claims.
