Waterproof carrying bag

Abstract

A waterproof carrying case formed from a soft flexible material using dielectric welding. A main body of the bag carries a interlocking closure member fused in the open top and sealed against the main body by a pair of end sleeves positioned over a corner of the main body and the closure member. A pair of opening loop handles is secured to the main body adjacent the closure member. By pulling on the loop handles, a user can open tightly closed interlocking closure.

1 . A carrying case, comprising: 
 a main body having an open top;    a closure member secured in the open top of the main body; and    a pair of opening members secured to the main body adjacent the open top of the main body, said opening members extending outwardly from the main body.    
   
   
       2 . The carrying case of  claim 1 , wherein said closure member comprises a interlocking closure member.  
   
   
       3 . The carrying case of  claim 1 , wherein said opening members are adapted for grasping by a user's hands and pulling in opposing directions to facilitate opening of the interlocking closure member.  
   
   
       4 . The carrying case of  claim 1 , wherein each of said opening members comprises an attachment member fixedly secured on an outside of the main body and a loop member carried by the attachment member.  
   
   
       5 . The carrying case of  claim 4 , wherein said loop member is sized to allow grasping by a human hand.  
   
   
       6 . The carrying case of  claim 4 , wherein said loop member is sized to allow positioning of at least human fingers therein.  
   
   
       7 . The carrying case of  claim 1 , further comprising a means for sealing a line of attachment of the closure member to the main body to prevent seeping of moisture into the interior of the carrying case.  
   
   
       8 . The carrying case of  claim 7 , wherein said sealing means comprises a pair of sealing sleeves mounted about respective ends of the closure member and configured to overlap at least a portion of an adjacent corner of the main body.  
   
   
       9 . The carrying case of  claim 8 , wherein each of said sealing sleeves is fused to the main body and to the closure member.  
   
   
       10 . The carrying case of  claim 1 , wherein said main body is formed from a flexible moisture-impermeable material capable of being welded by dielectric welding.  
   
   
       11 . A carrying case, comprising: 
 a flexible main body having an open top, said body being formed from liquid-impermeable material;    an interlocking closure member secured in the open top of the main body;    a pair of sleeves sealingly engaging and overlapping opposing ends of the closure member and covering a line of attachment of the closure member to the main body; and    a pair of opening members secured to the main body adjacent the open top of the main body, said opening members extending outwardly from the main body.    
   
   
       12 . The carrying case of  claim 11 , wherein each of said opening members comprises an attachment member fixedly secured on an outside of the main body and a loop member carried by the attachment member, said loop member being configured for grasping by a human hand.  
   
   
       13 . The carrying case of  claim 12 , wherein said loop member is sized to allow positioning of at least human fingers therein.  
   
   
       14 . The carrying case of  claim 11 , wherein each of said end sleeves is sized to cover at least a portion of the main body.  
   
   
       15 . A method of forming a soft-sided carrying case, comprising the steps of: forming a main body from a piece of flexible material, said main body having an open top and closed sides and bottom; 
 securing a closure member in the open top of the main body and fusing said closure member to the main body;    providing a pair of end sleeves and positioning said sleeves in an overlapping relationship over at least a part of the closure member and the main body;    fusing said end sleeves to the main body and the closure member; and    providing opening members and securing the opening members to the main body adjacent the closure member.    
   
   
       16 . The method of  claim 15 , wherein said closure member comprises interlocking closure member.  
   
   
       17 . The method of  claim 15 , further wherein said steps of fusing the closure member and the end sleeves comprise the step of dielectric welding.  
   
   
       18 . The method of  claim 15 , further comprising the step of opening said formed carrying case to allow access to the interior of the formed carrying case.  
   
   
       19 . The method of  claim 16 , wherein the step of opening the carrying case comprises the steps of grasping said opening members and bending the closure member to case a gap to form between parts of the closure member, and then applying a pulling force on the opening members, thereby forcing the parts of the closure member apart.  
   
   
       20 . The method of  claim 15 , wherein said main body is formed from a moisture-impermeable material.
