An adaptable, cleanable beverage container, generally for athletic use, with an enlarged opening at the top for depositing materials and flavors, a removable base for ease of cleaning, and an optionally insertable column removably connected to said removable base for securing a cooling or heating fluid or gel into the container. Optionally, the beverage container walls can be insulated with a hearing or cooling gel or other liquid for providing temperature control.

A bottle having a reclosable and resealable lid is disclosed. The bottle can have a removable pedestal base. The base can elevate the remainder of the bottle off of the surface upon which the bottle is resting. The lid can have a seal for a drinking mouthpiece outlet and a pressure equalization port. The lid can have a concave indentation or seat aligned with a hinge connecting a top of the lid to a base or rim of the lid. When opened, the seat can rest against the lid rim, opening the lid to more than a 180 lid opening angle.

A heat exchanging thermal liquid container system that comprises a main body at least partially defining a liquid reservoir structured and operable to retain a liquid, and a phase change material (PCM) liner comprising a PCM liner PCM having a selected melting temperature, and/or at least one PCM pod. Each of the at least one PCM pod(s) comprising a respective PCM pod PCM having a respective selected melting temperature. Wherein the PCM liner and/or the at least one PCM pod are disposable within the liquid reservoir such that when a liquid is disposed within the liquid reservoir the liquid will contact at least one of the PCM liner and the at least one PCM pod such that thermal energy can be exchanged between the liquid and the respective at least one of the PCM liner PCM and the at least one PCM pod PCM.

A three layer vessel has: a vessel body; a first liner connected to the vessel body and configured within the vessel body; an outside gap formed between the first liner in the vessel body, the outside gap is at least partially evacuated to a lower pressure than atmospheric air pressure; a second liner connected to the vessel body and configured within the first liner; an inside gap formed between the first liner in the second liner; a thermal conductive fluid held within the inside gap; a vessel body rim is formed on the vessel body with the vessel body connects to the first liner. The vessel body rim has a vessel body rim joint connecting a first liner to the vessel body neck; and a first vertical portion is formed on the second liner, when the first vertical portion flares outwardly to a horizontal portion.
