1DESCRIPTION OF THE PREFERR:ED E~D3ODIMENTS
l i l Referring now to Fig. 1, a foam scrubbing device constructed and,arrang~d in accordance w/th the invention is ' :
1~5~0U8 sho~n generally as 10. Scrubbing device ~0 Llas a substantially diamond shape in plan view or a lemon shape and is ~ormed from a 1, irst dense foam layer 11 and a second porous foam layer 12 which are heat-sealed along a seam 13 bet~een dense layer 11 and porous layer 12. Scrubbing device 1~ is provided in a diamond shape as this configuration fits neatly in~o a user's hand and ~i ~ ovides end regions 15 and 16 which are convenient for xeaching generally hard to clean areas of the face and other portions ! of the body. In Figs. 2 and 3, foam scrubbing device 10 is ,~ I
o l~ shown in cross-section to illustrate the relative thickness of i dense layer 11 and porous layer 12 and a cleansing bar 14 sealed therebetween.
', In this exemplary embodiment, dense layer 11 is thinner i than porous layer 12, has a pore count of about 40 to 80 pores Il per lineal inch and may be provided in thicknesses ranging frorn l¦ about l/4 to l/2 inch thick. Preferably, dense layer 11 has about 60 pores per inch and is about 3/8 inches ~hick. Poro~ls layer 12 is thicker than dense layer 11, has a pore count o about 10 to i! 50 pores per lineal inch and may be p~ovided in thicknesses i ranging from about 1/2 to 3/4 inches thick. Preferably~ porous layer 12 has about 30 pores per lineal inch and is about 5/8 inches thick The thicknesses of foam layers ll and 12 a~e !
selected so that substantially equal amounts of cleanser wilL
pass through each foam layer 11 and 12~ Actual relative thick~esse are selected depending on the actual porosity oE the layers.
i .
115~00~ 1 i .
I' Foam scrubbing device lO o~ Figs. 1-3 is approximately ! 3 in~hes x 5 inches and about l inch thick Cleansing bar 14 1 ... ,.. ~.. j is a block of soap of about l l/2 inch x l inch x 112 in~h in thickness and may be of any conventional soap composition.
However, it has been found that foam scrubbing device 70 is ,, .
,~particularly well-suited for cleansing generaLly difficult skin l~conditions when cleansing ba~ 14 is a deep cleansing soap ~jcomprising glycerine which will be descri~ed in~more detail below. A foam scrubbing devico of this size is convenient for ! cleansing facial skin and it is to be recognized that ~he size may be increased for body cleansing and massaging.
i The foam material utilized for forming foam layers ll ~and 12 of foam scrubbing device lO may be any conventional foam material, but pre~erably is a polyester foam available ¦with different physical characteristics. These polyester foams find typical applications in weather stripping7 insulation, protective pac~aging, air fi~tra~ion, cushions and ~he like.
Proper selection of physical properties of the polyester foams I makes them particularly well-suited for use in ~he foam scrubbing i devices constructed and arranged in accordance with the invention.l In this exemplary embodiment of the invention, dense . i~, I
foam layer ll is formed from a flexible polyester-polyurethane ` foam having about 60 pores per lineal inch. Porous foam layer `; 12 is also formed from the same flexible polyester-polyurethane .
I
;
1~800~ j ~. , foam material having about 30 pores per lineal inch. NominaLly, ' both layers have a density o~ about 2 pouncls per cubic foot. I~e ,~ density of the ~oam material may vary Erom about 2 to 4 pounds per cubic foot. In all cases~ the selected oam ma~erial should be ~lexible to semi-r~gid in order to provide sufficient abrasiveness for ef~ective cleansing. The coarseness of the ¦I polyester foam selected will vary depending whether the scrubbing j ¦' device is to be used for face cleansing and massaging, for the . head, body or feet. For example, a rigid foam will be selectea ~O j~ or treating dandruf~ and similar scalp conditions. Or course, ¦, the composition of the cleansing soap bar sealed in the scrubbing device will correspondingly vary for each intended use.
1~ Several deep cleansing glycerine soap composi~ons have ¦ been found to be particularly well-suited for use with ~oam ¦` scrubbing device lO. Three of these particular formulations are li set forth in the examples in the ~ol~owi~g Table and are set forth as illustrative of the inven~ion and not intended in a i limiting sense. In each case, the percentages given are in weight percents, based on the total weigh~s of tl~e composition.

!` The oam scrubbing device including a deep cleanslng ~ sub-composition of the type illustrated in Example 1 is par-`` ticu~arly well-suited for deep cleansing. The buffing and ; Loaming action o the deep cleansing composition o~ Example 1 helps remove dirt, whiteheads, b~ackheads and dead skin cells.
. In addition, it cleanses oily skin and helps controL acne pimples.
20 - ' It gives the skin a fresh, clean~ healthy and natural look. It has been found ~hat a foam scrubbing device o this type foams L,; ~ easilyJ washed reely and lasts about i~ ~o ~ days with three , cleansing applications per day. At ~his time the devices were il i~ -8-!i , I .

disposed in order to maintain cleanliness ancl eliminate the danger of re-infection or contamination.
; A foam scrubbing device including a soap of the com-position of the ~ype illustra~ed in E~ample 2 is also well suited for cleansing when an acne condition exists and is e~fective for drying oily slcin. A foam scrubbing device including a cleansing bar of the type illus~ra~ed in Example 3, is par-ticularly well-suited for deep cleansing of dry-skin.
The particular composition of the cleansing bar may be o varied. For example the glycerine content may vary from about . 3 to 25 weight percent. The amount of sodium soap resulting ` from coconut oil, tallow and castor oil as illustratedg or any other fat or oil capable of yielding a sufficiently hard soap bar, may vary from about 35 to 60 weight percent of the cleansing 1 bar. Preferably, the saponified castor accounts for about 1 to 5 I weight percent. Similarly, the sugar content, shown as sucros~
Il or example, may vary from about 10 to 30 weight percentr I Ethylenediaminetetraacetic acid, illustrated as a chileting ~ ' agent, is not essential, but preerably is present from about " 3 to 15 weight percent.
If the foam scrubbing device is to be used for drying oily skin, an effective amount of suitable drying agents wil~ be added to the composition of Example 1. Similarly, if dry skin is to be treated, additional cosmetic oils, such as almond oil, Ii !
,'coconut b~tter, mineral oil and the like may be added as sho~7n ~ in Example 3. Of course, an eEective amount of a fragrance may ''be added ~o these various compositions.
,I Referring now to Fig. 4, a generally round cy1indrical " shaped foam scrubbing device 18 constructed in accordance with il the invention is shown. Foam scrubbing device 18 is formed j~ from a dense foam layer l9 and a porous foam layer 20 sealed i~ along a seam 21 between dense foam layer l9 and porous foam 1~ layer 20. ~ glycerine cleansing bar 22 is sealed between dense ¦, foam layer 19 and porous foam layer 20. In Fig. 5, a foam ¦i scrubbing device 24 having a substantially rectangular shape ~¦ is shown generally as 24. Foam scrubbing device 24 is formed ; from a dense foam layer 25 and a porous foam layer 26 sealed at I a seam 27 therebetween. A glycerine cleansing bar 28 is sealed ¦ between the foam layers 25 and 26.
I According~y, by constructing and arranging a foam ¦ scrubbing device in accordance with the invention~ a scrubbing device for providing deep cleansing action for varying skin ~ conditions is provided. The flexib~e to semi-rigid foam utilized 20 I provides a mild abrasive action to help control acne pimples, i whiteheads and blackheads. By including a relatively thick , porous foam layer and a relatively thin dense foam layer5 i; substantially equal amounts of cleanser will pass ~hrough each i layer. In addition, the varying shapes of the devices of the ,, ., i.
invention, allo~s deep cleansing and generally inaccessible areas, i such as creases around the nose and chin. Most signi~icantly, !' a foam scrubbing device arranged in accordance with the invention avoids contamination and re-infection as it is designed to be disposable after a relatively short period of use.
~i It ~ill thus be seen that the objects set forth above, j, among those made apparent from the preceding description, are i! efficiently attained and, since certain changes may be made in li the above construction without departing from the spirit and lo !~ scope of the invention, it is intended that all matter contained ,i in the above description or shown in the accompany drawings shall be interpreted as illustrative and not in a limiting sense. ¦
