A container is disclosed that comprises an outer vessel having an inner cavity, and an inner vessel having an inner cavity. The inner vessel and outer vessel are configured for receiving all or substantially all of the inner vessel through an opening in the outer vessel such that in operation, said opening of the inner vessel may be releasably positioned proximate the opening of the outer vessel. The container also includes a lid for releasably enclosing said inner vessel within said outer vessel. The outer container may be made from a material called TRITAN and the inner vessel may be made from glass. A seal may be provided between the top to the inner vessel and the lid.

An insulated food and/or beverage container system includes an outer insulated container with a cylindrical body portion and a removable outer container lid that is configured to sealingly engage with the cylindrical body portion so as to minimize thermal transfer with an outside environment; and an inner container configured to fit within the outer insulated container, the inner container defining an interior cavity for holding food and/or a beverage, and the inner container including one or more first elements that are configured to matingly engage with one or more second elements on the cylindrical body portion of the outer insulated container so that the inner container is able to fully and securely nest inside the outer insulated container without any spinning or significant rattling. The outer insulated container and the inner container collectively provide enhanced insulating characteristics.

A modular insulated bottle for liquids includes an inner cylindrical container to hold a liquid that is surrounded by an external case. In an embodiment, the cylindrical container is glass and the external case is a translucent thermoplastic material. A gasket is removably and sealingly engageable to the top opening of the inner cylindrical container. A shoulder fitting secures over the gasket and is threadedly engaged to the external case. The gasket has a threaded top opening such as a spout that is configured to engage with one or more caps to adapt the bottle for different functions. A footer cap engages with a footer of the external case and creates a secondary storage compartment for items such as snacks, powders and/or pills.

Disclosed embodiments relate to a removable insert structure, which may be formed of glass and configured to be disposed within an outer vessel. The insert structure may have a sipping portion configured to extend out of the open end of the outer vessel. In some embodiments, the cross-sectional width of the sipping portion may vary, for example from the shoulder end to the sipping end. For example, the cross-sectional width of the sipping portion may be wedge-shaped, with the width at the sipping end being less than the width at the shoulder end. Insulated containers including removable insert vessels and lids for use with insulated containers are also disclosed.

A drinking vessel includes an outer vessel, a deformable retaining flange, and a removable insert structure formed of glass and configured to be disposed within the outer vessel. The insert structure may have a sipping portion configured to extend out of the open end of the outer vessel and the deformable retaining flange is configured to releasably retain the insert structure within the outer vessel.

A flask has an insulated outer container having an upper opening and an inner container having an upper opening. The flask has a lid that is configured to removably attach to the outer container and to form a substantially watertight seal with the outer container The inner container is slidably and removably housed within the outer container.
