Abstract

This invention relates to a delivery system which comprises a topical skin care agent, a top layer and a bottom layer where at least one of said top layer and said bottom layer comprises an apertured film having protuberances therein, where said top layer and said bottom layer are attached to eachother leaving a pouch between said top layer and said bottom layer, where said protuberances of said apertured film face said pouch, and where said pouch contains said topical skin care agent.

Claims

exact text as granted — not AI-modified
We claim:  
     
         1 . A delivery system comprising 
 a topical skin care agent,    a top layer,    and a bottom layer 
 where at least one of said top layer and said bottom layer comprises an apertured film having protuberances therein,  
 where said top layer and said bottom layer are attached to eachother leaving a pouch between said top layer and said bottom layer,  
 where said protuberances of said apertured film face said pouch, and  
 where said pouch contains said topical skin care agent.  
   
     
     
         2 . The delivery system of  claim 1 , wherein the topical skin care agent is selected from one or more members of the group consisting of oatmeal, colloidal oatmeal, oilated colloidal bath treatment, surfactant based colloidal oatmeal cleanser, cleanser systems, and soy powder.  
     
     
         3 . The delivery system of  claim 1  wherein said top layer and said bottom layer comprise an apertured film.  
     
     
         4 . The delivery system of  claim 1  wherein said top layer and said bottom layer comprise an apertured film which is laminated to a natural fiber or a synthetic fiber hydrophobic nonwoven material.  
     
     
         5 . The delivery system of  claim 4  wherein the hydrophobic nonwoven material is a bicomponent spunbound nonwoven.  
     
     
         6 . The delivery system of  claim 5  wherein the bicomponent spunbound nonwoven material is selected from the group consisting of PGI 6757, PGI 67DCO, and PGI 6705.  
     
     
         7 . The delivery system of  claim 1  wherein the apertures of either said top layer or said bottom layer have a size ranging from about 25 microns to about 100 microns.  
     
     
         8 . The delivery system of  claim 1  wherein the apertures of either said top layer or said bottom layer have a size ranging from about 50 microns to about 75 microns.  
     
     
         9 . The delivery system of  claim 1  wherein the number of apertures per square centimeter of film of either said top layer or said bottom ranges from about 10 to about 50 apertures.  
     
     
         10 . The delivery system of  claim 1  wherein the number of apertures per square centimeter of film of either said top layer or said bottom layer ranges from about 15 to about 40 apertures.  
     
     
         11 . The delivery system of  claim 1  wherein either said top layer or said bottom layer is selected from the group consisting of natural fiber and synthetic fiber hydrophobic nonwoven materials.  
     
     
         12 . The delivery system of  claim 1  wherein, said topical skin care agent is contained in a water-soluble film.  
     
     
         13 . The delivery system of  claim 12  wherein, said water-soluble film is selected from the group consisting of polyvinyl alcohol, polyvinyl acetate, and cellulose derivatives.  
     
     
         14 . The delivery system of  claim 12  wherein, said top layer and said bottom layer comprise an apertured film having a bicomponent spunbond nonwoven material laminated to said apertured film and said topical skin care agent is collodial oatmeal.
