Credit card-shaped drug delivery system

Abstract

A credit card-shaped case is provided that includes first and second layers. Both the first and second layers are generally rigid and have a generally planar outer surface. The first and second layers are attached to one another and configured to provide a recess therebetween. The recess is configured to prevent moisture intrusion therein. At least one medicine or other chemical substance is contained within the recess.

1 . A case for carrying a chemical substance comprising: 
 a first layer being generally rigid and having a generally planar outer surface;    a second layer being generally rigid and having a generally planar outer surface, said first and second layers being attached to one another and configured to provide a recess therebetween, said recess configured to prevent moisture intrusion therein; and    at least one chemical substance contained in said recess.    
   
   
       2 . The case of  claim 1 , wherein said recess is located in said second layer.  
   
   
       3 . The case of  claim 1 , further comprising a moisture barrier, said moisture barrier at least covering a surface of said recess.  
   
   
       4 . The case of  claim 3 , wherein said moisture barrier is a foil layer.  
   
   
       5 . The case of  claim 1 , wherein said first and second layers are formed from plastic.  
   
   
       6 . The case of  claim 1 , further comprising a first cover generally covering said recess and attached at a perimeter of said recess.  
   
   
       7 . The case of  claim 6 , further comprising a second cover generally covering said recess and attached at a perimeter thereof, said cover disposed between said first cover and said recess and adapted to be more easily breakable than said first cover.  
   
   
       8 . The case of  claim 6 , wherein said first cover is moisture resistant.  
   
   
       9 . The case of  claim 1 , wherein said case has a thickness less than 0.08 inches.  
   
   
       10 . The case of  claim 1 , wherein said case is generally in the shape of a credit card.  
   
   
       11 . The case of  claim 1 , wherein said case includes at least two recesses.  
   
   
       12 . The case of  claim 11 , wherein said recesses include different chemical substances contained therein.  
   
   
       13 . The case of  claim 1 , wherein said chemical substance is an emergency medicine.  
   
   
       14 . The case of  claim 1 , wherein said case includes a list of symptoms, printed thereon, associated with an illness requiring said chemical substance.  
   
   
       15 . The case of  claim 1 , wherein said case includes instructions for usage thereon.  
   
   
       16 . The case of  claim 1 , wherein said recess includes a vapor barrier.  
   
   
       17 . The case of  claim 1 , wherein said recess is sealed around a perimeter thereof.  
   
   
       18 . The case of  claim 17 , wherein said sealed perimeter of said recess is adapted to identify when said sealed perimeter has been broken.  
   
   
       19 . The case of  claim 18 , wherein a chemical reaction occurs when said seal is broken thereby causing a color change of said sealed perimeter.  
   
   
       20 . The case of  claim 1 , further comprising a middle layer disposed between said first and second layers, said middle layer having said recess therein.  
   
   
       21 . The case of  claim 20 , wherein said recess extends completely through said middle layer.  
   
   
       22 . The case of  claim 20 , wherein said recess extends partially through said middle layer.  
   
   
       23 . The case of  claim 20 , wherein said middle layer includes a first side and a second side, each of said first and second sides having at least one of said recesses therein.  
   
   
       24 . The case of  claim 1 , wherein said first layer includes at least one tare strip.  
   
   
       25 . The case of  claim 24 , wherein said second layer includes at least one tare strip.  
   
   
       26 . The case of  claim 1 , wherein said first layer includes at least one tare portion, said tare portion generally aligned with said recess.  
   
   
       27 . The case of  claim 26 , wherein said first layer includes at least two tare strips and said first and second layers include at least two recesses disposed therebetween, each of said tare strips being generally aligned with at least one of said recesses.  
   
   
       28 . The case of  claim 1 , wherein said first and second layers are generally rectangular in shape and have generally similar lengths and widths, said first and second layers being generally aligned with one another and having at least three sides fixedly attached to one another.  
   
   
       29 . The case of  claim 1 , wherein said first layer includes an edge relief portion.  
   
   
       30 . The case of  claim 1 , wherein said first layer includes a recess for receiving said second layer.  
   
   
       31 . The case of  claim 1 , wherein said first layer includes a bendable tab portion disposed along an edge thereof to facilitate removal of the second layer from the first layer.
