DETAILED DESCRIPTION

While the present disclosure may be susceptible to embodiment in different forms, there are shown in the drawings, and herein will be described in detail, embodiments with the understanding that the present description is to be considered an exemplification of the principles of the disclosure and is not intended to limit the disclosure to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings.

Dry storage bag 11 is configured to store items that the user of the bag would like to keep dry, as shown for example, in FIG. 1. Dry storage bag 11 includes an annular side wall 20 and a bottom wall 22 coupled to the annular side wall 20. Side wall 20 and bottom wall 22 form a product receiving chamber 17 with dry storage bag 11. Bottom wall 22 is coupled to side wall 20 by sonic welding, RF welding or other coupling means such as bonding with an adhesive. Dry storage bag 11 also includes an annular rim 15 that defines a mouth opening into the product receiving chamber 17.

The annular sidewall 20 of the dry storage bag is configured to be rolled up by a user at an end opposite the bottom wall 22 to seal the opening and close off the product receiving chamber, as shown in FIG. 9. The bag 11 also includes an adjustable harness strap 14 that is configured to extend from the bottom wall 22, along the annular side wall 20 and to the mouth of the bag 11, as shown in FIG. 1. When the overall length of the harness strap 14 is shortened through adjustment by tightening the slide buckles, the harness strap 14 exerts a compressive force on the bag 11 to compress the bag 11 and the contents in the product receiving chamber.

The bag 11 also includes a containment patch 18 coupled to the bottom wall 22 and configured to generally limit lateral movement (side to side movement) of the adjustable harness strap 14 without restricting linear movement of the harness strap 14 through the containment patch 18 during tightening of the harness strap 14 around the bag 11, as shown in FIG. 4. The containment patch 18 maintains the position of the harness strap 14 on bottom wall 22 so that it remains generally centered during tightening of the harness strap 14. This results in uniform compression of the dry bag 11 so that one portion of the side wall 20 is not compressed further by the strap 14 than the other side.

The bag 11 also includes a handle 36 positioned to lie near the bottom wall 22 of the bag 11 and proximate to the containment patch 18, as shown in FIG. 4. The handle 36 is adapted to permit the bag 11 to be carried by a user after the bag 11 has been filled and sealed. The handle 36 includes a first and second ends 37, 39 that are coupled to the bag 11 at the perimeter of the bottom wall 22. Ends 37, 39 are connected to the bag 11 at a position that is perpendicular to the direction of the harness strap 14 so that the handle 36 does not interfere with the operation of the harness strap 14.

The harness strap 14 is preferably a two piece configuration. The harness strap 14 includes a first portion 21 that is positioned to lie near the mouth of the bag 11, as shown in FIG. 1. The first portion 21 of the harness strap 14 is coupled to the mouth of the bag 11 so that when the annular side wall 20 of the bag is rolled up, the first portion 21 of the harness strap 14 is rolled up along with the annular side wall 20. The harness strap 14 includes a second portion 23 that passes loosely through containment patch 18. Both the first and second portions 21, 23 include buckle portions that can be coupled together to form a continuous strap.

The bottom wall 22 of dry storage bag 11 is preferably plastic welded to the annular side wall 20 so that no holes are placed in the material, as shown in FIG. 1. This makes the construction waterproof. The containment patch 18 is also plastic welded to the bottom wall 22. The containment patch 18 includes an opening to allow the harness strap 14 to pass through. The harness strap 14 is free to move through the opening in the containment patch 18. The bottom wall 22 and the annular side wall 20 are preferably made from the same flexible material. This allows both pieces to flex at the same rate and allows the material to be compatible for use of the plastic welding process. The harness strap is used to prevent the annular sidewall 20 from unrolling until desired by the user.

The strap containment & compression system 10 on bag 11 allows for stitch free construction of the waterproof bag 11 while providing the ability to compress said bag 12, as shown in FIG. 1. Harness strap 14 is secured to the bag 11 and is made of a continuous piece of material and is free moving within the contained area 16 of containment patch 18, allowing for the compression force from the continuous piece of harness strap 14 to pull against itself on each side of bag 11. Note, compression comes from one continuous piece of strapping itself as it is not stitched or tethering to the side wall 20 or bottom wall 22 of bag 11. This arrangement allows for maximum bag compression.

The containment patch 18 is sealed or welded (sonic welded or the like) to the bag 11 to provide for a waterproof construction. The containment patch 18 is oval in shape and has a perimeter edge 24, as shown in FIG. 1. Perimeter edge 24 has an attachment zone 26 that is sealed or welded to the bottom wall 22 of bag 11. The containment patch 18 includes a pair of slits 28, 30 to create a passageway that allows for the unrestricted passage of the harness strap 14. The harness strap 14 includes a first portion 21 that is coupled to the opening of the bag 11. The first portion 21 includes the first halves of a pair of buckle fasteners 32, 34.

Containment web strap 14 includes a second portion 23 that is configured to include the second portions of the buckle fasteners 32, 34 when the mouth of the bag is rolled down to seal the opening of the bag 12. Containment harness strap 14 is coupled at its ends to buckle fasteners 32, 34 and pulled tight to compress containment harness strap 14 around the bag. Since containment patch 18 does not restrict the movement of the containment harness strap 14, the strap 14 can move freely to evenly compress the bag 12.

In use, a user puts their goods into the opening of the bag into the product receiving chamber 17 within. The user next rolls the side walls of the bag downwardly toward the bottom, which contains the first portion 21 of the harness strap 14. Once the sidewalls are rolled, the user next couples the end portions of the fasteners 32, 34 together and pulls the ends of the harness strap 14 tightly to compress the containment web strap 14 around the bag 12. Since containment patch 18 only guides containment web strap 14, strap 14 is allowed to move freely and evenly compress the bag 12. Once compressed, a user can grab handle 36 formed at the bottom wall 22 of the bag 12 and carry the bag.

The present design allows the bag 12 to be constructed without any stitched or patched areas to prevent leaking. This design provides for a stronger and more durable design than stitched and or patched straps and allows for uniform compression to the bag 12.
