FIELD OF THE INVENTION

The invention relates to the field of skin care.

BACKGROUND OF THE INVENTION

In the field of aesthetics, it is well known to produce pedicure systems including basins which contain heated, roiling water. Known systems are:

_• relatively costly to manufacture

_• hard to clean

_• prone to breakdown

SUMMARY OF THE INVENTION

Forming one aspect of the invention is a disposable for use with a structure having a vessel surface that defines a vessel for receiving liquid, the disposable comprising a pad and a layer. The pad has a pair of surfaces spaced apart from one another by a tubular sidewall. The pad is permeable to air flow and one of the pair of surfaces is positioned, in use, against the vessel surface. The layer overlies the other of the pair of surfaces and is at least substantially impermeable to air flow. In use, gas is introduced into the pad and issues through the sidewall in the form of bubbles.

According to another aspect, the one of the pair of surfaces can be a self-adhesive surface adapted to hold the disposable against the vessel surface in use.

According to another aspect, the disposable can further comprise a release film overlying the self-adhesive surface; and the self-adhesive surface and the release film can be adapted such that the release film can be removed by hand from the pad to expose the self-adhesive surface for use. According to another aspect, the pad can define a central void; and the disposable can further comprise a tube that extends through the sidewall and into the void.

According to another aspect, the pad can be a foam having about 60 pores per inch.

According to another aspect, the pad can be about 1/8” thick.

According to another aspect, the foam can have properties of about: density 40 kg/m3

tensile strength 108 kpa

elongation 184%

resilience 45%

tearing strength 6.19 N/cm

Forming yet another aspect of the invention is a system for use with a structure having a surface that defines a bowl for receiving water, the system comprising

• the disposables; and

• apparatus adapted to produce a flow of heated air and to couple to a disposable such that, in use, a flow of heated air issues through the sidewalls into the water contained in the bowl to produce heated, roiling water in the bowl.

Advantages, features and characteristics of the invention will become apparent upon a review of the following detailed description and the appended drawings, the latter being briefly described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Components of a bubble generation system 20 according to an exemplary embodiment of the invention are shown in Figure 1 and will be seen to include a disposable 22 and a pump unit 24

The disposable 22 will be seen in Figure 3 to comprise a pad 26, a seal 28, a release film 30 and a tube 32.

The pad 26:

_• is about 1/8” thick

_• has a tubular sidewall 34

_• has a pair of surfaces 36,38 spaced apart from one another by the tubular sidewall 34, one 38 of the pair of surfaces being a self-adhesive surface

_• is permeable to air flow

_• defines a central void 40

_• is an open cell foam having properties of about: porosity 60 pores per inch.

density 40 kg/m 3

tensile strength 108 kpa

elongation 184%

resilience 45%

tearing strength 6.19 N/cm

The open cell nature of the foam is evident from Figure 5.

The seal 28 is a film layer that overlies the other 36 of the pair of surfaces and is at least substantially impermeable to air flow.

The release film 30 lies against the self-adhesive surface 38.

The tube 32 extends through the sidewall 34 and into the void 40.

An exemplary manner of construction of the disposable is evidenced by Figure 4. Herein it will be seen that

_• a layer of open cell foam of the contemplated type, over which a film layer 42 is overlaid and the release layer is underlaid, is die stamped to define the sidewall 34, the central void 40 and a channel 44;

_• the tube 32 is fitted into the channel 44;

_• a film patch 48 is welded to the film layer 42 to overlie the channel 44 and void 40, the patch 48 and layer 42 collectively defining seal 28

As shown in Figure 1 , the pump unit 24 is defined by a compressor 46 and a conditioner 48.

The compressor 46 is adapted to produce a flow of air and is not further detailed, as it is conventional.

The conditioner 48 is shown in Figure 2 and will be seen to include a heater 50, a transformer 52 and an ozone generator 54. The heater 50 is a 400W solid state diode heater, adapted to heat throughpassing air. The step up transformer 52 produces 10000VAC which powers the ozone generator 54, to produce ozone.

The exemplary system is adapted for use with pedicure spa vessels; a prior art vessel of this type is shown in phantom in Figure 6.

For use, and all as indicated in Figures 6 and 7:

_• the release layer 30 is removed from one of the disposables, thereby exposing the self- adhesive surface 38, which, in turn, is secured to the vessel surface;

_• the pump unit 24 is coupled to the tube 32

_• water is placed in the vessel

_• the pump unit is activated, thereby to cause heated, ozonated air to: travel through tube 33 into the void 40; traverse the foam; issue through the sidewall 34 in the form of bubbles, thereby producing heated, disinfected roiling water in the vessel. Persons of ordinary skill will readily appreciate the advantages associated with the system:

_• the disposable can be removed and replaced regularly, with commensurate advantages in terms of hygiene

_• the disposable is relatively inexpensive to construct

_• the pump is relatively inexpensive to construct and operate, and relatively durable

Whereas a specific embodiment is shown, it will be evident that variations are possible.

For example, whereas a self-adhesive layer is shown, this is not strictly necessary as a second impermeable layer could be provided in the place of the self-adhesive layer and the disposable could be secured, for example, by hook and loop fasteners.

Accordingly, the invention should be understood to be limited only by the accompanying claims, purposively construed.
