1 CLEANSING/SKIN-CARE PRODUCT DISPENSER The present invention relates to a dispenser of cleansing products and/or skin-care products. The term "cleansing product" used herein relates to all cleansing products such as soaps, detergents or shower gels. The term "skin-care product" relates to all conventional skin-care products such as moisturisers. The dispenser has particular, but not exclusive, application in the dispensing of liquid and/or gel products.

eleoo oO .".Soaps for washing have been supplied in a bar form for many years. These soap bars are prone to mushing and cracking. The bars also leave undesirable soap deposits on •coo the wash basin or soap dish. The soap bar is difficult to hold while bathing in that the wet surface of the soap is slippery. As a further point soap bars are prone to loss of perfume when exposed to air. They can also have a drying Seffect on the skin.

In view of these problems soap is often sold in a liquid form which is dispensed from pump operated dispensers, the pump being located in the dispenser cap. Shower gels are conventionally sold in flexible bottles, the gels being dispensed by squeezing the bottle causing the gel to exit via a nozzle in the bottle cap. These dispensers are designed to release liquid soap or gels into a hand prior to application to the skin. These dispensers are not designed to be rubbed

~I

on the skin, as with a soap bar, in order to dispense the soap or gel onto the body.

According to the present invention there is provided a cleansing product and/or skin-care product dispenser for rubbing over a body, said dispenser comprising a wall defining a chamber for receiving the cleansing and/or skin-care product, wherein at least one slit is provided in the wall for dispensing the product, the parts of the wall defining the slit being abutted S when the dispenser is not being used to actively dispense Sees..

the product and the said parts of the wall being o" separable by flexing the wall in order that the product 0 may be actively dispensed via the slit and wherein the 0 dispenser further comprises a valve, said valve being

OSSS

disposed so as to facilitate the equalisation of air pressure within and outside the dispenser in order that .555 the product may be easily dispensed from the dispenser.

.555 Thus the invention provides a fully enclosed container which dispenses cleansing products and/or skin-

S

care products through outlets on the application of a small force to the dispenser wall. The dispensing of the product will cease when the applied force is removed.

The applied force may be achieved by rubbing the dispenser over the body in a similar manner to a soap bar.

The parts of the wall defining the slit are ideally RA4 -0 0

NT

of reduced thickness compared to the remainder of the wall. This makes the slit more responsive to pressure applied to the wall.

Ideally the valve is a one-way valve allowing air into the chamber, but not allowing any product to exit the chamber.

At least a part of the outer surface of the dispenser wall may be coated with an absorbent material, such as a fabric or a plurality of fibres. This enhances the cleansing action and sensation by retaining a finite amount of product from any previous applications, promoting a lathering action, augmenting the contact area during rubbing and stimulating tactile sensations. The absorbent material may be impregnated with at least one cleansing and/or moisturising product. The coating may be applied by a flocking process in which a plurality of 0fibres are flocked onto adhesive located on the outer 000* *999 surface of the dispenser wall. The use of such a coating would usually produce a lathering action within 3 seconds.

The dispenser may be refilled by injection through 0 one of the slots or the means for pressure equalisation.

9090 The dispenser may be shaped and/or textured so as to facilitate easy gripping by a hand. The apparent density of the filled dispenser is ideally less than 1.0, thus allowing the dispenser to float in water.

4 The dispenser may be made from any suitable material such as plastics. Thermoplastics such as thermoplastic polyurethane are ideal materials.

In order that the present invention may be more readily understood a specific embodiment thereof will now be described by way of example only with reference to the accompanying drawings in which:- Fig.l is a plan view of one dispenser in accordance with the present invention; Fig.3 is a longitudinal cross-sectional view through the dispenser of Figs. 1 and 2; Fig. 4 is an exploded view of the slit arrangement shown in Fig.3 when the slit is closed; and is an exploded view of the slit arrangement shown in Fig.3 when the slit is open.

Referring to the drawings a dispenser 10 of cleansing compositions and/or skin-care products comprises a soap-bar shaped body made from a flexible plastics wall 11. The wall 11 defines a chamber 12 in which is located the cleansing composition and/or skin-care product. Three one-way valves 14 are located in the top of the dispenser. These valves 14 allow air to enter the dispenser, but do not allow the material contained in the chamber 12 to exit. Three slits are provided in the base of the dispenser. The parts of the wall of the dispenser located adjacent the slit 15 are of reduced thickness as can be seen in Fig.4.

A plurality of fibres 16 are adhered to the underside of the bar. These fibres 16 retain a measure of the material dispensed from the chamber 12 so that rubbing the device over oooo a skin surface can produce a lathering action within, say three seconds.

When not in use the walls 11 of the dispenser are not compressed and the parts of the dispenser wall 11 defining the slits 15 abut such that substantially none of the material e•9 oe contained within the chamber can exit the bar (see Fig.4).

t.

S" When in use the dispenser is rubbed along the surface of 9 9999 the skin, thus compressing the walls 11 of the dispenser and prising apart the parts of the wall defining the slit 15 (see Now the material 13 contained in the chamber 12 can escape between the parts of the wall which define the slit as those parts no longer abut. The one way valve 14 allows air to enter the chamber thus allowing for the equalisation of air pressure within and outside the dispenser.

It is to be understood that the above described -6embodiment of the invention has been described by way of example only. Many modifications and variations are possible. For example any number of valves or slits may be provided.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
