Description

Title: Bags and Carrier Systems Thereof

[0001] This patent application claims the benefit of priority from U.S. Provisional Application Serial 63 / 556,022 filed February 21, 2024, teachings of which are herein incorporated by reference in their entirety.FIELD

[0002] Various bags including carrier bags, backpacks and dry pouches with rollable or foldable top portions as well as slings and dry cubes and carrier systems inclusive of the bags are provided.BACKGROUND

[0003] Soft waterproof carriers or containers are used in the outdoor market for backpacks, bags of all types including duffle bags, shoulder bags, camera bags, stuff bags, and the like. These carriers protect their contents against rain, dew, and mist and perhaps being dunked in a stream or lake. A problem facing waterproof soft carriers is how to seal an opening provided in the carrier to allow insertion and removal of objects to and from an interior compartment.

[0004] Bags are available with what are described as watertight or water-proof zippers.

[0005] However, zippers that are designed to resist the passage of water and / or gas when closed must be completely closed in order to prevent passage of water or gas. This requires care on the part of the user. "Waterproof" zippers share another characteristic in addition to beinghighly water-resistant when closed. The slides of these zippers are difficult to move compared to ordinary zippers. The slides of waterproof zippers offer noticeable resistance to being moved because the slides are compressing or sgueezing sealing material together when the zipper is closed (or opening such material when the zipper is opened) on either side of the coiled or toothed zipper. Accordingly, persons using carriers are less likely to open and close such zippers because of the necessary exertion unless the zipper must be opened to allow access to the interior of the carrier or closed to positively prevent ingress of water.

[0006] Further, waterproof zippers must be kept clean of sand, dust, and debris in order to be waterproof because the sealing material will not be able to properly close around the coils or teeth of a waterproof zipper if sand, dirt, dust, or other debris obstructs the sealing material. A carrier with an open waterproof zipper therefore should be kept away from sand, dust, and debris in order to not degrade the function of the waterproof zipper. The zipper may need to be cleaned if it is exposed to sand, dust, or debris .

[0007] Published U.S. Patent Application No. 2018 / 0078008 discloses a carrier with a waterproof primary or internal zipper closing an opening in one or more walls that define an otherwise waterproof interior compartment of the carrier. The carrier provides a flap connected to the exterior of one or more of the walls in such a way as to be able to cover and thereby protect the opened waterproof zipper from sand, dust, or debris. The flap may be moved from a first position in which the flap covers and protects the waterproof zipper to a second position away from the waterproof zipper inorder to permit access to the waterproof zipper and the opening to the interior compartment.

[0008] Another solution to providing a waterproof closure is to provide a carrier made of waterproof material having an opening at the end of a tube long enough that the tube can be rolled up to close the opening. The rolled-up tube typically is secured by a two-piece interlocking buckle in which a first piece of the buckle is attached by a strap to one side of the end of the tube and the second piece by a second strap to the other side of the end of the tube. Alternatively, hook-and-loop fabric may be employed to secure the rolled-up tube. Dry bags used in paddle sports and other outdoor pursuits often have a rolled-up tube closure .

[0009] U.S. Patent 8,302,749 discloses a storage system comprising a first enclosure that forms an outer carrier including fastener openings and a second enclosure that forms a inner carrier, wherein the inner carrier is stored within the outer carrier, wherein the inner carrier includes an opening, a roll top mechanism, a first set of fasteners at opposite ends of the opening and disposed at a first end of the inner carrier, and a second set of fasteners disposed at a second end of the inner carrier opposite the first end, wherein the second set of fasteners are configured to engage the first set of fasteners, wherein the inner carrier includes an open configuration wherein the opening is open such that an interior of the inner carrier is accessible and a closed configuration wherein edges of the opening contact each other to close the opening and the roll top mechanism formed by the edges of the closed opening is rolled over at least one time, and wherein in the closed configuration thesecond set of fasteners of the inner carrier extend from an interior of the outer carrier to an exterior of the outer carrier through the fastener openings and are attached to the first set of fasteners of the inner carrier.

[0010] Published U.S. Patent Application No. 2014 / 0254956 discloses a waterproof bag comprising an impermeable material forming a waterproof enclosure wherein an internal contained space is defined therein, and having an opening for access to the contained space, and a rollable top portion configurable in an unrolled state exposing the opening and a rolled state enclosing the opening therein; a horizontal waterproof zipper closure mechanism sealingly secured to the impermeable material around the opening, and movable between an open position allowing access through the opening and a closed position forming a waterproof seal preventing passage through the opening; and interengagement couplings for retaining the rollable top portion in the rolled state; wherein rolling the rollable top portion over the opening increases the resistance of the closure mechanism to separation resulting from pressure due to submersion at a depth.

[0011] There is a need for light-weight, easy to close, water-resistant bags.SUMMARY OF THE INVENTION
