Erasable writing system

Abstract

A system including a writing instrument having a body with a marking portion and an eraser portion, wherein the marking portion is configured to dispense a permanent ink and the eraser portion is configured to dispense a solvent which solubilizes the permanent ink and a writing surface upon which the marking portion can dispense the permanent ink, wherein the writing surface is part of a school or office product.

1 . A system comprising: 
 a writing instrument including a body having a marking portion and an eraser portion, wherein the marking portion is configured to dispense a permanent ink and said eraser portion is configured to dispense a solvent which solubilizes said permanent ink; and    a writing surface upon which said marking portion can dispense said permanent ink, wherein said writing surface is part of a school or office product.    
   
   
       2 . The system of  claim 1  wherein said school or office product is selected from the group consisting of a binder, a notebook, a folder, a divider, a portfolio, a book cover, a compact disk case, a computer case and an electronic equipment case.  
   
   
       3 . The system of  claim 1  wherein said writing surface includes a polymeric material that is chemically resistent to said solvent.  
   
   
       4 . The system of  claim 1  wherein said writing surface is made of polypropylene or polyethylene.  
   
   
       5 . The system of  claim 1  wherein said writing surface is located on a front cover of said school or office product.  
   
   
       6 . The system of  claim 1  wherein said writing surface is located on a spine of said school or office product.  
   
   
       7 . The system of  claim 1  wherein said school or office product includes at least one flap pivotally attached to said product, said flap being movable between a closed position wherein said flap covers at least a portion of said writing surface and an open position wherein said flap does not cover said writing surface.  
   
   
       8 . The system of  claim 7  wherein said at least one flap includes a flap writing surface capable of being marked upon by permanent ink, wherein said flap writing surface is chemically resistant to at least one solvent capable of solubilizing said permanent ink.  
   
   
       9 . The system of  claim 8  wherein said flap writing surface is part of a binder, a notebook, a folder, a divider, a portfolio, a book cover, a compact disk case, a computer case or an electronic equipment case.  
   
   
       10 . The system of  claim 8  wherein said flap writing surface includes a polymeric material selected from the group consisting of polyethylene and polypropylene.  
   
   
       11 . The system of  claim 7  further comprising at least one securing device for securing said flap to said writing surface.  
   
   
       12 . The system of  claim 7  wherein, when said flap is in said closed position, said flap covers about 10% to about 50% of said writing surface.  
   
   
       13 . The system of  claim 7  wherein, when said flap is in said closed position, said flap covers about 50% to about 75% of said writing surface.  
   
   
       14 . The system of  claim 7  wherein, when said flap is in said closed position, said flap covers about 75% to about 100% of said writing surface.  
   
   
       15 . The system of  claim 8  wherein said flap has a supplemental flap writing surface on an opposite side of said flap writing surface.  
   
   
       16 . The system of  claim 7  wherein said school and office product is a binder having a spine, a front cover and a back cover, wherein said front and back covers are pivotally attached to said spine and wherein said flap is pivotally coupled to a free edge of said front or back cover.  
   
   
       17 . The system of  claim 1  wherein said school and office product is a folder having a front cover pivotally coupled to a back cover, wherein said back cover has a top edge that extends beyond a top edge of said front cover and includes a pen/pencil holder fixedly attached to said top edge of said back cover.  
   
   
       18 . The system of  claim 1  wherein said school and office product is a book cover having a front cover portion, a back cover portion and a closure mechanism, wherein said front cover portion is adapted to be received over the front cover of a book and said back cover portion is adapted to be received over the back cover of a book.  
   
   
       19 . A school or office product comprising: 
 a spine;    a front cover pivotally attached to said spine;    a back cover pivotally attached to said spine; and    a writing surface located on at least one of said spine, said front cover and said back cover, wherein said writing surface is capable of being marked upon by a permanent ink and is chemically resistant to at least one solvent capable of solubilizing said permanent ink.    
   
   
       20 . The school or office product of  claim 19  wherein said writing surface includes a polymeric material selected from the group consisting of polyethylene and polypropylene.  
   
   
       21 . The school or office product of  claim 19  wherein said writing surface is a part of said front cover.  
   
   
       22 . The school or office product of  claim 19  further comprising at least one flap pivotally attached to said front cover for covering a portion of said front cover.
