Embodiments include anti-sloshing liquid-retaining bottles that comprise an internal bladder configured to expand in volumetric proportion to the liquid expelled from the liquid containing bottle thereby eliminating air and, by extension, space in which the water could slosh. Anti-sloshing liquid-retaining bottles disclosed herein can rely on various mechanisms for volumetrically expanding the bladder against liquid retained in the bottle, mechanisms include pneumatic modulation of the bladder using a regulator configured to introduce pressure from a high pressure reservoir to inflate or expand the bladder and valves to release the pressure and deflate the bladder, as well as mechanisms for spring actuation to expand or inflate the bladder. Additional embodiments of anti-sloshing liquid-retaining bottles include bottles comprising wave breakers for passively preventing sloshing by dampening the motion. ## Claims ### Claim 1 An anti-sloshing bottle, comprising: an outer shell defining a liquid retention compartment configured for storing non-carbonated liquid; a high-pressure reservoir defining an air retention compartment configured to maintain a pressure of less than or equal to 100 psi; a bladder fluidically coupled to a reduced pressure compartment, wherein the bladder is disposed within the outer shell, such that the bladder is configured to expand and contract within the outer shell in response to changes in pressure generated by the reduced pressure compartment; a purge button configured to close and open a release valve configured to vent the bladder to an atmosphere external to the outer shell; a pressure regulator assembly comprising a regulator housed between the reduced pressure compartment and an air retention compartment, wherein the regulator is configured to maintain a pressure differential between the reduced pressure compartment and the air retention compartment such that the pressure differential in the reduced pressure compartments is less than the pressure in the air retention compartment, and wherein the pressure in the air retention compartment is sufficient to expand or contract the bladder against the stored non-carbonated liquid; and a mouthpiece configured to expel the non-carbonated liquid using pressure generated by the force of the bladder against the non-carbonated liquid stored in the liquid retention compartment formed by surfaces comprising the outer shell and the bladder. ### Claim 2 (depends on 1) The anti-sloshing bottle of claim 1, wherein air retention compartment is configured to maintain an initial pressure range of 40-100 psi. ### Claim 3 (depends on 1) The anti-sloshing bottle of claim 1, wherein the air retention compartment is configured to maintain a pressure range of 10 psi to 80 psi after one fill cycle. ### Claim 4 (depends on 1) The anti-sloshing bottle of claim 1, wherein the air retention compartment is configured to maintain a pressure range of 10 psi to 60 psi after two or more fill cycles. ### Claim 5 (depends on 1) The anti-sloshing bottle of claim 1, wherein the outer shell is irreversibly coupled to the air retention compartment such that the irreversible coupling comprises a seal configured to generate an air tight space between the outer shell and air retention compartment. ### Claim 6 (depends on 1) The anti-sloshing bottle of claim 1, wherein the outer shell is reversibly coupled to the air retention compartment, wherein the reversible coupling comprises a seal configured to generate an air tight space between the outer shell and the air retention compartment. ### Claim 7 (depends on 1) The anti-sloshing bottle of claim 1, further comprising a fill valve configured to pressurize the air retention compartment, wherein the air retention compartment is pressurized with air from the atmosphere external to the anti-sloshing water bottle. ### Claim 8 (depends on 7) The anti-sloshing bottle of claim 7, wherein the air retention compartment is pressurized to a pressure range of 30-60 psi. ### Claim 9 (depends on 1) The anti-sloshing bottle of claim 1, wherein the reduced pressure compartment is configured to retain a pressure of less than or equal to 40% of the pressure of the air retention compartment. ### Claim 10 (depends on 1) The anti-sloshing bottle of claim 1, wherein the pressure of the air in the reduced pressure compartment is reduced by a factor of 1-30 by the regulator disposed between the reduced pressure compartment and the air retention compartment. ### Claim 11 (depends on 1) The anti-sloshing bottle of claim 1, wherein the liquid retention compartment is configured for storing less than or equal to 24 ounces of non-carbonated liquid. ### Claim 12 (depends on 1) The anti-sloshing bottle of claim 1, wherein the bladder is configured for storing less than or equal to 710 cubic centimeters of air. ### Claim 13 (depends on 1) The anti-sloshing bottle of claim 1, wherein the mouthpiece further comprises a bite valve configured to utilize pressure supplied from the bladder to expel liquid from the liquid retention compartment at a constant rate, wherein a rate of liquid expulsion is determined by the regulator of the pressure regulator assembly. ### Claim 14 (depends on 1) The anti-sloshing bottle of claim 1, wherein a volume of air in the reduced pressure compartment is configured to expand in volume with the expansion of the bladder such that the bladder volumetrically displaces liquid as the liquid is expelled through the mouthpiece. ### Claim 15 (depends on 1) The anti-sloshing bottle of claim 1, wherein the regulator of the air retention compartment is configured to expand the reduced pressure compartment comprising a volume of the bladder such that the bladder compresses the liquid retained in the liquid retention compartment to a pressure range of 1-5 psi. ### Claim 16 (depends on 1) The anti-sloshing bottle of claim 1, wherein the bladder is configured to deflate and release air into the atmosphere through a purge or release valve. ### Claim 17 (depends on 1) The anti-sloshing bottle of claim 1, wherein the regulator is a diaphragm regulator configured to keep the bladder at a constant pressure. ### Claim 18 (depends on 1) The anti-sloshing bottle of claim 1, further comprising a depressible purge button configured to open and close a purge or release valve. ### Claim 19 (depends on 1) The anti-sloshing bottle of claim 1, further comprising a depressible button configured to open and close the regulator housed within the pressure regulator assembly. ### Claim 20 (depends on 1) The anti-sloshing bottle of claim 1, further comprising a depressible purge button configured to open the release or purge valve and close the regulator or the pressure regulator assembly or close the release valve and open the regulator of the pressure regulator assembly.
