Dry Bag Harness System

Abstract

A dry bag harness system for use with a roll top dry bag. The harness system allows for stitch free construction of a waterproof bag to provide use of compression straps around the perimeter of the bag. The webbing or strap is one continuous piece, and is free moving within the contained area. The containment system includes a patch that is sealed or welded to the bag to provide for a waterproof and airtight construction. The patch includes a passageway for the strap to allow the strap to slide within the patch while the strap is being tightened around the bag. The dry bag is constructed without any stitched areas and this arrangement allows the strap to apply even pressure to the bag when cinching the web type strap.

1 . A dry storage bag comprising:
 a flexible annular side wall;   a bottom wall connected to the side wall, the annular side wall formed to include a mouth opening into a product receiving chamber, the annular sidewall configured to be rolled up at an end opposite the bottom wall to seal the opening and close off the product receiving chamber;   an adjustable harness strap that is configured to extend from the bottom wall, along the annular side wall and to the mouth of the bag wherein when the overall length of the harness strap is shortened, the harness strap exerts a compressive force on the bag to compress the bag; and   a containment patch coupled to the bottom wall and configured to generally limit lateral movement of the adjustable harness strap without restricting linear movement of the harness strap during tightening of the harness strap around the bag.   
     
     
         2 . The dry storage bag of  claim 1 , wherein the harness strap includes at least one adjustment buckle to allow the length of the harness strap to be shortened or lengthened. 
     
     
         3 . The dry storage bag of  claim 2 , wherein a portion of the harness strap is positioned to lie near the mouth of the bag. 
     
     
         4 . The dry storage bag of  claim 3 , wherein the portion of the harness strap is coupled to the mouth of the bag so that when the annular side wall of the bag is rolled the portion of the harness strap is rolled along with the annular side wall. 
     
     
         5 . The dry storage bag of  claim 1 , wherein the bottom wall is plastic welded to the annular side wall. 
     
     
         6 . The dry storage bag of  claim 5 , wherein the containment patch is plastic welded to the bottom wall. 
     
     
         7 . The dry storage bag of  claim 1 , wherein the containment patch includes an opening to allow the harness strap to pass through. 
     
     
         8 . The dry storage bag of  claim 7 , wherein the harness strap is free to move through the opening in the containment patch. 
     
     
         9 . The dry storage bag of  claim 8 , wherein the bottom wall and the annular side wall are made from the same flexible material. 
     
     
         10 . A dry storage bag comprising:
 a flexible bottom wall;   an annular side wall formed to include a mouth opening into a product receiving chamber, the annular sidewall configured to be rolled up by a user at an end opposite the bottom wall to seal the opening and close off the product receiving chamber;   an adjustable harness strap that is configured to extend from the bottom wall, along the annular side wall and to the mouth of the bag wherein when the overall length of the harness strap is shortened through adjustment, the harness strap exerts a compressive force on the bag to compress the bag;   a containment patch coupled to the bottom wall and configured to generally limit lateral movement of the adjustable harness strap without restricting linear movement of the harness strap during tightening of the harness strap around the bag; and   a handle positioned to lie near the bottom wall of the bag and proximate to the containment patch, the handle being adapted to permit the bag to be carried.   
     
     
         11 . The dry storage bag of  claim 10 , wherein the harness strap includes at least one adjustment buckle to allow the length of the harness strap to be shortened or lengthened. 
     
     
         12 . The dry storage bag of  claim 11 , wherein a portion of the harness strap is positioned to lie near the mouth of the bag. 
     
     
         13 . The dry storage bag of  claim 12 , wherein the portion of the harness strap is coupled to the mouth of the bag so that when the annular side wall of the bag is rolled up, the portion of the harness strap is rolled up along with the annular side wall. 
     
     
         14 . The dry storage bag of  claim 10 , wherein the bottom wall is plastic welded to the annular side wall. 
     
     
         15 . The dry storage bag of  claim 14 , wherein the containment patch is plastic welded to the bottom wall. 
     
     
         16 . The dry storage bag of  claim 10 , wherein the containment patch includes an opening to allow the harness strap to pass through. 
     
     
         17 . The dry storage bag of  claim 16 , wherein the harness strap is free to move through the opening in the containment patch. 
     
     
         18 . The dry storage bag of  claim 17 , wherein the bottom wall and the annular side wall are made from the same flexible material. 
     
     
         19 . The dry storage bag of  claim 13 , wherein the harness strap is used to prevent the annular sidewall from unrolling until desired by the user.
