An intake regulating container for fitness activities is shown and described. The container has volume indicators such that adjacent pairs of the volume indicators define a volume of food or beverage contained between the volume indicators. A physical activity descriptor describing an amount of a physical activity (e.g., sets and repetitions of weightlifting exercises or distance traveled for running or jogging) is provided and is located to correspond to an indicator and/or an adjacent pair of the volume indicators, thereby providing a container that relates a physical activity and amount of the activity to a volume of contained food or beverage consumed.

A holster assembly for use in retaining liquid containers includes a holster clip and a holster cup holder. The holster clip and the holster cup holder are configured to be selectively attached and detached from one another.

The systems and methods provide a container assembly comprising: a container having a known storage capacity for storing a liquid; an additive dispensing assembly, the additive dispensing assembly dispensing variable, non-zero quantities of one or more additives into the liquid stored in the container; one or more vessels that each contain one of the additives, of the one or more additives, to be dispensed into the liquid; and a gas dispensing assembly, the gas dispensing assembly releasing a gas into the liquid stored in the container, and the gas dispensing assembly including: an onboard gas tank; a valve assembly; and a gas outlet, and the valve assembly controlling flow of gas from the onboard gas tank, through the valve assembly, and to the gas outlet so as to output the gas into the liquid; and wherein the valve assembly, to perform the controlling the flow of gas, is movable between: an open position, in which flow of gas is allowed to flow from the onboard gas tank to the gas outlet; and a closed position in which the flow of gas is prevented to flow from the onboard gas tank to the gas outlet.

Disclosed are embodiments of containers, caps, sealing assemblies, and associated components. In one embodiments, a sealing assembly can include an expander actuator operatively coupled to an expander, which expander is operatively coupled to a seal. In a locking state, the expander actuator is configured to cause the expander to expand horizontally against the seal. The expansion of the seal against a shoulder and/or a neck of a container provides a locking, leak-proof seal. In an opening state, the expander is configured to provide an upward movement of the expander actuator, allowing the expander to return to its unexpanded form, which in turn causes the seal to return to its unexpanded form. When the seal is in its unexpanded form, the sealing assembly (along with an associated cap) can be pulled away from the container body.
