Semi-enclosed applicator for distributing a substance onto a target surface

Abstract

A semi-enclosed applicator for distributing a substance onto a target surface including a first side having a first internal surface and a first external surface, a second side having a second internal surface and a second external surface, an internal cavity between said first and second sides, at least one externally accessible opening, and a flexible film reservoir containing a product. At least a portion of the flexible film reservoir of said flexible film reservoir is disposed between said external surfaces of said first side and said second side.

1 . A semi-enclosed applicator for distributing a substance onto a target surface, said applicator comprising: 
 (a) a first side having a first internal surface and a first external surface;    (b) a second side having a second internal surface and a second external surface;    (c) an internal cavity between said first and second sides;    (d) at least one opening, such that said internal cavity is externally accessible; and    (e) a flexible film reservoir containing a product, at least a portion of said flexible film reservoir is disposed between said external surfaces of said first side and said second side, the flexible film reservoir comprising a distribution channel, wherein said flexible film reservoir further comprises a plurality of compartments each containing a product, said plurality of compartments being adapted to provide at least one function, wherein said function is selected from the group consisting of mixing, multiple dispensing and sequential dispensing.    
   
   
       2 . The semi-enclosed applicator of  claim 1 , wherein said flexible film reservoir is located within said first side.  
   
   
       3 . The semi-enclosed applicator of  claim 1 , further comprising a substantially fluid-impervious barrier layer within said internal cavity, wherein said flexible film reservoir is outwardly located from said substantially fluid-impervious barrier layer.  
   
   
       4 . The semi-enclosed applicator of  claim 1 , wherein said flexible film reservoir is rupturable.  
   
   
       5 . The semi-enclosed applicator of  claim 4 , wherein said flexible film reservoir is rendered rupturable by frangible seal.  
   
   
       6 . The semi-enclosed applicator of  claim 5 , wherein said flexible film reservoir is folded proximate to said frangible seal.  
   
   
       7 . The semi-enclosed applicator of  claim 6 , wherein said flexible film reservoir has a first burst force when folded and a second burst force when unfolded, said first burst force being greater than said second burst force.  
   
   
       8 . The semi-enclosed applicator of  claim 1 , wherein said flexible film reservoir further comprises at least one exit location.  
   
   
       9 . (canceled)  
   
   
       10 . The semi-enclosed applicator of  claim 8 , wherein said flexible film reservoir further comprises a distribution head through which said product is adapted to be released remote from said reservoir.  
   
   
       11 . (canceled)  
   
   
       12 . The semi-enclosed applicator of  claim 5 , wherein said frangible seal has at least one stress concentrator.  
   
   
       13 . The semi-enclosed applicator of  claim 3 , further comprising a second substantially fluid-impervious barrier layer within said internal cavity.  
   
   
       14 . The semi-enclosed applicator of  claim 13 , further comprising a second flexible film reservoir containing a second product.  
   
   
       15 . The semi-enclosed applicator of  claim 1 , wherein said flexible film reservoir is comprised of a material capable of varying seal strengths.  
   
   
       16 . The semi-enclosed applicator of  claim 1 , wherein said first side is a substantially non absorbent structure.  
   
   
       17 . The semi-enclosed applicator of  claim 1  wherein said second side is a substantially absorbent material.  
   
   
       18 . The semi-enclosed applicator of  claim 1 , further comprising a friction enhancing element located at least partially within said internal cavity during use.  
   
   
       19 . The semi-enclosed applicator of  claim 1 , wherein said at least on of said first and second sides is textured.  
   
   
       20 . The semi-enclosed applicator of  claim 1 , wherein said flexible film reservoir is located to avoid inadvertent dispensing.  
   
   
       21 . The semi-enclosed applicator of  claim 1 , wherein said applicator is used as one of the following group: window cleaning, bathroom cleaning, kitchen cleaning, furniture dusting and polishing, body cleaning, teeth cleaning, car vinyl protectant, herbicide applicator, skin lotion application, baby clean-up.  
   
   
       22 . The semi-enclosed applicator of  claim 1 , further comprising a temperature-changing element.  
   
   
       23 . The semi-enclosed applicator of  claim 1 , wherein at least a portion of one of said first and second sides is differently extensible.  
   
   
       24 . The semi-enclosed applicator of  claim 1 , wherein at least one of said first and second sides is comprised of one or more removable layers.  
   
   
       25 . (canceled)  
   
   
       26 . (canceled)  
   
   
       27 . (canceled)  
   
   
       28 . A flexible film pouch comprising said distribution channel further comprises at least one unsealed region that extends beyond an entrance to distribution channel, said at least one unsealed region being adapted to prevent crimping of a fluid pathway in said distribution channel.
