The rolling water container system according to various examples of the disclosure can provide easier transportation of the water, lifting of the water container or drum, and accessibility to the inside of the drum. Additional features can assist with conservation of water by preventing water leakage from the drum and providing for near-complete emptying of the drum. Further features can include handles with greater mechanical strength. ## Claims ### Claim 1 A rolling liquid container, comprising: a drum configured for containing the liquid, the drum including a center body and two sides; and a filtration receptacle within the drum; wherein the drum includes a first shoulder between the center body and one of the sides, the first shoulder is tapered at an angle relative to the center body and configured to allow the drum to balance and rest on the first shoulder at the angle during storage or liquid removal. ### Claim 2 (depends on 1) The rolling liquid container of claim 1, further comprising: a second shoulder between the center body and the other of the sides; and a cap formed in the second shoulder for providing an aperture in the drum. ### Claim 3 (depends on 1) The rolling liquid container of claim 1, further comprising a handle rotatably coupled to the sides of drum and configured for rolling the drum along the center body. ### Claim 4 (depends on 1) The rolling liquid container of claim 1, the drum further including a pour assist gutter, the pour assist gutter including a shelf and a cap embedded in the shelf, the pour assist gutter configured for directing liquid from inside the drum onto the shelf and to the cap. ### Claim 5 (depends on 4) The rolling liquid container of claim 4, the pour assist gutter further including a lip at a border of the shelf for retaining liquid on the shelf. ### Claim 6 (depends on 1) The rolling liquid container of claim 1, wherein the filtration receptacle is bag-shaped. ### Claim 7 (depends on 1) The rolling liquid container of claim 1, the drum further including a filtered liquid outlet. ### Claim 8 (depends on 1) The rolling liquid container of claim 1, the drum further including a detachable pump for drawing liquid through the filtration receptacle. ### Claim 9 (depends on 1) The rolling liquid container of claim 1, wherein the drum is configured for separating into component parts to enable placement of the filtration receptacle within the drum. ### Claim 10 (depends on 1) The rolling liquid container of claim 1, wherein the drum includes internal fins, the fins containing filters and configured for forcing liquid through the filters when the drum is rotated. ### Claim 11 (depends on 10) The rolling liquid container of claim 10, wherein the fins include removable filters and apertures on the fins for removing the filters. ### Claim 12 (depends on 1) The rolling liquid container of claim 1, further comprising a filtered water reservoir and an unfiltered water reservoir within the drum. ### Claim 13 (depends on 12) The rolling liquid container of claim 12, further comprising a detachable first tap for draining water from the filtered water reservoir and a detachable second tap for draining water from the unfiltered water reservoir. ### Claim 14 (depends on 3) The rolling liquid container of claim 3, wherein the handle is detachable and the drum is configured for placement in at least one of a storage and dispensing configuration when the handle is detached. ### Claim 15 (depends on 3) The rolling liquid container of claim 3, further comprising a braking system in the handle, the braking system including a lever and configured for immobilizing the drum unless the lever is engaged. ### Claim 16 (depends on 3) The rolling liquid container of claim 3, wherein the handle is coupled to wheels configured as hubs for the drum. ### Claim 17 (depends on 16) The rolling liquid container of claim 16, wherein the handle is configured for use as a dolly when detached from the drum. ### Claim 18 (depends on 3) The rolling liquid container of claim 3, wherein the handles are coupled to hub torsion springs. ### Claim 19 (depends on 1) The rolling liquid container of claim 1, further comprising a first cap for the drum, the first cap oriented along a rolling axis of the drum, and a handle rotatably coupled to the first cap at the rolling axis of the drum. ### Claim 20 (depends on 19) The rolling liquid container of claim 19, further comprising a second cap formed within the first cap. ### Claim 21 (depends on 1) The rolling liquid container of claim 1, further comprising a generator rotatably coupled to the drum for generating electricity as the drum is rolled. ### Claim 22 (depends on 21) The rolling liquid container of claim 21, further comprising a charger coupled to the generator for charging a mobile device. ### Claim 23 (depends on 21) The rolling liquid container of claim 21, further comprising a refrigeration unit within the drum, the refrigeration unit coupled to the generator for cooling liquid within the drum.
