Disclosed herein are fluid bladders that include a port and a port closure, a handle, and/or other components. Some disclosed closures can be configured to provide at least two different sized openings for accessing the reservoir, as well as providing a sealing and/or locking mechanism to close the port and seal the port. Exemplary closures comprising a base defining a fill port and mounted to a wall of the bladder, a first cap component that is attached to the base, and a second cap component (e.g., a lid) that is attachable and detachable (via threaded engagement, a pivoting snap fit, or otherwise) to the first cap component. The base can be fixed (e.g., welded) to the bladder to cover the bladder wall opening and provide a second, rigid opening, or port. The first cap component is coupled to the base and can overlie the port or be positioned around the port (optionally providing a third, smaller opening), and the second cap component can cover the first cap component to completely seal off the port and prevent fluid passage in or out of the bladder. The first cap component can include a lid release and locking mechanism.

1. A fluid container comprising: a flexible bladder having an internal region for storing a fluid and an opening for allowing passage of fluid in or out of the internal region;a closure secured to the bladder over the opening of the bladder, wherein the closure comprises: a base secured to the bladder around the opening, the base having a port to allow passage of fluid through the base in or out of the bladder;an annular cap retainer secured to the base around the port; anda cap hingedly coupled to the cap retainer and pivotable between a closed position where the cap seals the port closed and an open position where the port is open for passage of fluid in or out of the bladder;wherein the cap retainer comprises a retainer mechanism that engages and secures the cap in the closed position and a release actuator button that disengages the cap from the retainer mechanism when depressed by a user; anda handle positioned adjacent to the port such that the fluid container can be held by the handle while filling the bladder through the port;wherein the handle is a portion of the base defining a gripping region. 2. The fluid container of claim 1, wherein the cap retainer comprises a locking mechanism comprising a curved member that is slidably adjustable back and forth between a locked position wherein the release actuator button is disabled by the position of the curved member behind the retainer mechanism and an unlocked position wherein the release mechanism is unimpeded by the curved member and the release actuator button is enabled. 3. The fluid container of claim 2, wherein the locking mechanism further comprises a lock actuator that extends from the curved member at a location spaced apart from the retainer mechanism and the release actuator button, wherein a user can slide the lock actuator to adjust the curved member between the locked position and the unlocked position. 4. The fluid container of claim 1, wherein the gripping region comprises two opposing lateral recesses situated for gripping the handle. 5. The fluid container of claim 1, wherein the retainer mechanism is configured to engage and secure an engagement member of the cap when the cap is in the closed position, and wherein depressing the release actuator button disengages the engagement member from the retainer mechanism and allows the cap to move to the open position. 6. The fluid container of claim 1, wherein the base is secured to a front wall of the bladder and an interface between the base and the front wall of the bladder defines a bladder plane, wherein the port of the base includes an inner circumference that defines a port plane, the port plane being perpendicular to a primary flow direction through the port, and wherein the base is shaped such that the port plane is at an acute angle relative to the bladder plane. 7. The fluid container of claim 1, wherein the handle is fixed to the bladder along an entire length of the handle. 8. A fluid container comprising: a flexible bladder having an internal region for storing a fluid and an opening for allowing passage of fluid in or out of the internal region;a closure secured to the bladder over the opening of the bladder, wherein the closure comprises: a base secured to the bladder around the opening, the base having a port to allow passage of fluid through the base in or out of the bladder;an annular cap retainer secured to the base around the port; anda cap hingedly coupled to the cap retainer and pivotable between a closed position where the cap seals the port closed and an open position where the port is open for passage of fluid in or out of the bladder;wherein the cap retainer comprises a retainer mechanism that engages and secures the cap in the closed position and a release actuator button that disengages the cap from the retainer mechanism when depressed by a user; anda handle positioned adjacent to the port such that the fluid container can be held by the handle while filling the bladder through the port;wherein the base is secured to a front wall of the bladder and an interface between the base and the front wall of the bladder defines a bladder plane, wherein the port of the base includes an inner circumference that defines a port plane, the port plane being perpendicular to a primary flow direction through the port, and wherein the base is shaped such that the port plane is at an acute angle relative to the bladder plane. 9. The fluid container of claim 8, wherein the cap retainer comprises a locking mechanism comprising a curved member that is slidably adjustable back and forth between a locked position wherein the release actuator button is disabled by the position of the curved member behind the retainer mechanism and an unlocked position wherein the release mechanism is unimpeded by the curved member and the release actuator button is enabled. 10. The fluid container of claim 9, wherein the locking mechanism further comprises a lock actuator that extends from the curved member at a location spaced apart from the retainer mechanism and the release actuator button, wherein a user can slide the lock actuator to adjust the curved member between the locked position and the unlocked position. 11. The fluid container of claim 8, wherein the retainer mechanism is configured to engage and secure an engagement member of the cap when the cap is in the closed position, and wherein depressing the release actuator button disengages the engagement member from the retainer mechanism and allows the cap to move to the open position. 12. The fluid container of claim 8, wherein the cap retainer is permanently secured to the base. 13. The fluid container of claim 8, wherein the cap retainer is detachable from the base and the cap retainer is reattachable to the base. 14. The fluid container of claim 8, wherein the handle is fixed to the bladder along an entire length of the handle. 15. A fluid container comprising: a flexible bladder having an internal region for storing a fluid and an opening for allowing passage of fluid in or out of the internal region;a closure secured to the bladder over the opening of the bladder, wherein the closure comprises: a base secured to the bladder around the opening, the base having a port to allow passage of fluid through the base in or out of the bladder;an annular cap retainer secured to the base around the port; anda cap hingedly coupled to the cap retainer and pivotable between a closed position where the cap seals the port closed and an open position where the port is open for passage of fluid in or out of the bladder;wherein the cap retainer comprises a retainer mechanism that engages and secures the cap in the closed position and a release actuator button that disengages the cap from the retainer mechanism when depressed by a user; anda handle positioned adjacent to the port such that the fluid container can be held by the handle while filling the bladder through the port;wherein the handle is fixed to the bladder along an entire length of the handle. 16.
