A beverage supply apparatus includes cooling device 6, milk tank 5 in storage chamber 6a of cooling device 6, and detection device 7 that detects the milk. Detection device 7 has first light guide body 7c to penetrate partition wall 12 having a multilayer box body that partitions storage chamber 6a, second light guide body 7d to penetrate partition wall 12 which faces first light guide body 7c, light projection unit 7a attached to partition-wall outer-surface-side end of first light guide body 7c to project light via the body 7c, and light receiving unit 7b attached to the partition-wall outer-surface-side end of second light guide body 7d to receive light transmitted through milk tank 5 via second light guide body 7d. The detection device detects the presence or absence of or the remaining amount of milk based on a light reception state in the light receiving unit 7b.

An adapter having a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting a liquid to or from a container, by applying a load to the male coupling after inserting it into the female coupling, the load being provided by the weight of a portion of the external device, the adapter being configured for insertion in a mouth of the container and secured therein using a stretchable membrane that fits snugly around the mouth of the container for obtaining a tight seal, the stretchable membrane having tabs for a user to grasp.

A portable, self-contained beverage apparatus includes a container assembly having a known storage capacity for storing a consumable liquid, and a dispensing assembly disposed within the container assembly that dispenses variable, non-zero quantities of additives into the consumable liquid. The dispensing assembly includes multiple apertures structured and arranged to retain vessels containing the additives to be dispensed into the consumable liquid. The beverage apparatus also includes a level sensor disposed within the container assembly that determines a consumable liquid level of the consumable liquid stored in the container assembly. In certain embodiments, one or more positive displacement pumping mechanisms are configured to pump additive liquid from additive containers into a beverage chamber.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.
