Abstract

An applicator for applying a cream or lotion or like substance to the skin and spreading the substance thereon to coat an area of the skin. An applicator head (5) defines an application surface (6) with at least one opening (8) therein for delivery of the substance. The application surface (6) has a substantially flat main area with an arcuate leading edge (7). A spreading lip (10) is disposed opposite the leading edge (7) and extends upwardly and rearwardly and tapers to a free edge to form a spreading blade tip. The leading edge is smoothly rounded to define a gradual transition between the main area of the application surface and a peripheral surface extending around the head to the position of the spreading lip.

Description

APPLICATOR, E.G. FOR SHAVING PREPARATIONS AND THE LIKE This invention relates to an applicator for applying a substance, such as a cream or lotion, to the skin and spreading it over an area of the skin. The applicator of the invention is especially suited to the application of preparations for use in shaving, in particular shaving cream, shaving gel or shaving foam with which a skin area is commonly coated prior to shaving with a safety razor, and the invention is specifically described herein with reference to use for applying shave preparations. It is to be understood, however, that the applicator can be used for other substances which are intended to be coated onto the skin. Shaving foams and self-foaming shaving gels are usually supplied in aerosol cans and most commonly they are spread onto the skin area to be shaved by means of the fingers or sometimes with a shaving brush onto which an appropriate quantity of the shaving foam or gel is delivered from the dispensing nozzle of the aerosol container. Use of the fingers tends to be rather messy and inconvenient, and for shaving foam and self-foaming gels a brush which is traditionally used to create a lather is not strictly needed. There is, therefore, a need for a more convenient method of applying shave preparations to the skin, and with this aim in mind the present invention proposes an applicator for applying a substance to the skin and spreading the substance thereon to coat an area of the skin, comprising an applicator head defining an application surface with at least one opening therein for delivery of a substance to the application surface, the application surface having a substantially flat main area with an arcuate leading edge, and a spreading lip disposed opposite the leading edge and extending upwardly and rearwardly with respect to the main area of the application surface, the spreading lip tapering to a free edge to form a spreading blade tip, the leading edge being smoothly rounded to define a gradual transition between the main area of the application surface and a peripheral surface extending around the head to the position of the spreading lip.

The applicator head can be conveniently mounted on a handle structure which can accommodate a reservoir containing the substance to be applied to the skin, and a control member can be provided on the handle structure to control delivery of the substance to the application surface of the head. More particularly the handle stmcture can have the form of a casing adapted to house a pressurized container in which the substance is supplied and stored, the pressurized container having a dispensing valve which is operable by means of the control member so that the substance flows from the container to the application surface of the applicator head. In another particular form the handle structure may define a reservoir and be equipped with a pump actuated by a button, lever or other member provided on the handle structure for delivery of the reservoir contents to the application surface. A further alternative is for the handle structure to comprise a squeeze-type container which allows the contents of the container to be delivered to the application surface by squeezing the container in the hand. With such applicators, a quantity of shaving preparation can be easily dispensed onto the application surface ready to be applied to and spread onto the skin. The applicator may be disposable, that is intended to be discarded when it has become emptied.

With the applicator of the invention the applicator head is not required to act as a temporary reservoir for the substance being applied, as a head of foam material would, and the applicator head can even be made of a hard material although some flexibility of at least the spreading blade tip is preferred. In a preferred construction the applicator head comprises a pad of resihently compressible material, in particular an elastomeric material which is non-absorbent and has a substantially continuous surface structure at the application surface, that is the surface is free from voids in which the substance is intended to be held temporarily in the course of being applied to the skin.

The pad is preferably dimensioned and configured to ensure comfort in use. Thus, the spreading lip is arcuate as seen in a direction peφendicular to the main area of the application surface, and the front face of the spreading lip is concavely curved to define a smooth transition with the main area of the application surface. Relatively shaφ corners on the pad are avoided and the leading edge is preferably rounded at a radius in the range of 3 to 12 mm. The spreading lip suitably projects above the plane of the main area of the application surface to a height in the range of 5 to 15mm. The minimum transverse dimension of the application surface, which is preferably the lateral dimension, is approximately in the range of 3.5 to 5.5 cms. An applicator of such dimensions is especially suited for application of substances over relatively large skin areas and for that reason is especially suited to use in applying shaving preparations to skin areas commonly shaved by females.

The above and other preferred features of the invention will be more fully understood from the following detailed description of a currently preferred embodiment of the invention, reference being made to the accompanying drawings in which:

Figure 1 is a front elevation of an applicator according to the invention suitable for applying self-foaming shaving gel to a skin area to be shaved;

Figure 2 is a side elevation of the applicator ;

Figure 3 is a rear elevation of the applicator ;

Figures 4 and 5 are perspective views showing the applicator from the front and rear respectively; and Figure 6 is an enlarged view showing the applicator head as seen in the direction of the arrow A in Figure 2; and

Figure 7 is a top plan view of a modified applicator having a different form of control member.

The self-foaming shaving gel applicator illustrated in the drawings has a rigid casing structure 1 which forms a handle with a main part of substantially cylindrical form suitably dimensioned so that it can be held comfortably in one hand. The casing 1 includes a detachable cover 2 to enable a pressurized container holding a supply of shaving gel to be replaccably inserted into the casing. As well known in the art the pressurized container is equipped with a dispensing valve which is operable to allow the pressurized contents to flow from the interior of the container to a discharge nozzle. The casing cover 2 is provided with a control member 3 enabling activation of the valve from outside the casing. As shown in Figures 1 to 5 the control member 3 consists of a button which can be depressed to operate the valve whereas in the modified container of Figure 7 the control member 3 is in the form of a lever which protrudes from the casing and may facilitate valve operation by means of the forefinger of a hand in which the applicator is held. At the upper end of the handle the structure defines a substantially circular mountings face which is inclined downwardly and forwardly and at which an applicator head in the form of a pad 5 is mounted. The applicator pad is made of a resihently compressible material so that it has a soft rather than hard feel when applied against the skin, a suitable material being an elastomer with a Shore A hardness of not less than 30, for example Kraton with 45 Shore A hardness. It is possible, however, for the applicator head to be of a hard, such as a rigid plastics material with hardness up to Rockwell R120. The pad 5 is shaped so that there are no shaφ corners or edges which could cause discomfort as the applicator is moved across the skin in use. The pad defines an application surface a main area 6 of which is substantially flat. The lower, leading edge 7 of the application surface is arcuate and extends through an arc of a little under 180°, and this edge is rounded at a relatively large radius, such as in the range of 3 to 12mm e.g. of about 5 to 7 mm, so that gradual contact will be made with the skin as the applicator is moved over the skin. A delivery duct passes through the pad 5 and opens into a slot 8 at the main area 6 of the application surface. The nozzle of the pressurized container which is housed in the casing is of course arranged to direct the shaving gel discharged from the container into the delivery duct so that it flows immediately out of the slot 8 onto the application surface. At its trailing edge the pad 5 has a spreading lip 10 which is inclined upwardly and rearwardly with respeGt to the plane of the main area 6 of the application surface, and there is a smooth concave transition between the area 6 and the front face 11 of the spreading lip 10. The spreading lip 10 tapers in thickness to its free edge to form a flexible blade tip which is able to flex in order to pass easily over any irregularities encounteied at a skin surface across which the lip is moved. Although the spreading lip 10 is arcuate as viewed in a direction peφendicular to the main area 6 of the application surface (Fig. 6), it can be seen that the free edge of this lip is substantially straight, and in particular slightly convex as viewed from the front. The height to which the spreading lip projects above the plane of the main area 6 of the application surface is suitably in the range of 7 to 12 mm.

The described applicator is easy and comfortable to use. The control button/lever 3 is operated so that an appropriate quantity of shaving gel is delivered to and is collected on the application surface after which it is applied to the skin with a series of strokes so that the spreading lip 10 spreads the shaving gel in a uniform coating over the skin area which is to be shaved. It may be noted that the applicator is not intended to produce any massaging effect SUGII as that normally associated with use of a shaving brush in a manner employed when it is desired to create a lather.

It should be understood that the foregoing description of the preferred embodiment is given by way of not limiting example only and that modifications are possible without departing from the scope of the invention as defined by the claims which follow. As one possible example of such a modification it may be mentioned that in place of the slot 8 two or more discrete openings could be provided for delivery and distribution of the shaving gel over the application surface of the applicator pad.
