Scent emitting patch and/or bandage

Abstract

A scent emitting patch remains securely attached to the skin of a wearer. The patch has an external top layer and backing layer with a skin-contacting portion. The skin-contacting segment contains an adhesive. At least one reservoir comprising pockets or microcapsules containing a scent is disposed in at least one portion of the backing layer. These pockets or microcapsules are operative to rupture upon application of pressure or scratching by the patch wearer. Upon rupture, scent is delivered to the skin to emit aroma. Pockets containing the scent are formed in the backing layer. Microcapsules, if present, are preferably incorporated in the adhesive. Scent is released at the skin-contact interface when pressure is applied to rupture the pockets or microcapsules, permitting controlled release at the wearer's election.

         22 . A scent emitting patch, comprising:
 a. an external top layer and a backing layer;   b. said backing layer having a skin-contacting segment opposite said external top layer, where at least one portion of said skin-contacting segment has an adhesive;   c. said skin-contacting segment being appointed for contact with the skin of a patch wearer;   d. a plurality of reservoirs constructed as microcapsules being disposed in said backing layer, said reservoirs containing a scent;   e. said backing layer being constructed from a first and a second polymeric sheets;   f. said first polymeric sheet containing said plurality of reservoirs constructed as microcapsules;   g. said second polymeric sheet being generally thinner and having a lower strength than said first polymeric sheet;   h. said second polymeric sheet being spread over said first polymeric sheet covering said microcapsules; and   i. said microcapsules being operative to rupture upon application of pressure by said patch wearer, thereby releasing said scent.   
     
     
         23 . A scent emitting patch as recited by  claim 22 , wherein said adhesive is selected from a group comprising acrylic based, dextrin based, and urethane based adhesives, and adhesives based on natural and synthetic elastomers. 
     
     
         24 . A scent emitting patch as recited by  claim 22 , wherein said scent is a perfume. 
     
     
         25 . A scent emitting patch as recited by  claim 22  comprising a central wound-contacting absorbent pad bonded by hot melt glue or strong adhesive to said backing layer to form a scent emitting bandage. 
     
     
         26 . A scent emitting patch as recited by  claim 22 , wherein a plurality of reservoirs are provided that are individually separated from one another. 
     
     
         27 . A scent emitting patch as recited by  claim 22 , wherein a plurality of reservoirs are provided that are interconnected with one another. 
     
     
         28 . A scent emitting patch as recited by  claim 22 , wherein said reservoir containing said scent is disposed within said skin-contacting segment of said backing layer. 
     
     
         29 . A scent emitting patch as recited by  claim 22 , wherein said reservoir containing said scent is disposed in said adhesive-containing portions of said backing layer. 
     
     
         30 . A scent emitting patch as recited by  claim 22 , wherein said reservoir contains about 5 to 20 volume percent of said scent as compared to said volume of said adhesive. 
     
     
         31 . A scent emitting patch as recited by  claim 22 , wherein said external top layer includes at least one portion having a plurality of apertures integrated therein and located in alignment with each of said reservoir/reservoirs containing said scent disposed in said backing layer. 
     
     
         32 . A scent emitting patch as recited by  claim 22 , wherein said plurality of portions of said skin-contacting segment of said backing layer containing said adhesive is located along an outer perimeter of said back layer. 
     
     
         33 . A scent emitting patch as recited by  claim 22 , wherein said plurality of portions of said skin-contacting segment of said backing layer containing said adhesive is located along two parallel side perimeters of said back layer. 
     
     
         34 . A scent emitting patch as recited by  claim 22 , wherein said external top layer is opaque. 
     
     
         35 . A scent emitting patch as recited by  claim 22 , further comprising at least one reservoir constructed as a microcapsule that is admixed within said adhesive and coated in said backing layer. 
     
     
         36 . A method for producing a scent emitting patch, comprising said steps of:
 a. producing microcapsules that contain a scent;   b. mixing said microcapsules with a skin-contacting adhesive to produce a microcapsule-containing adhesive;   c. selecting a backing layer;   d. coating at least one portion of said backing layer with said microcapsule-containing adhesive;   
       whereby release of said scent can be triggered on demand upon application of pressure to said backing layer, and consequent rupture of said microcapsules.
