An insulated container for food particulate and beverages is described. The insulated container includes a double-walled structure composed of a metal, and a glass structure arranged within a hollow interior of the double-walled structure. The glass structure includes a body and a sipping portion extending from the body. The sipping portion isolates the user's lips from contacting the double-walled structure. The glass structure may be repeatably removed for cleaning or replacement. The insulated structure includes a deformable flange that secures the glass structure to the double-walled structure. The insulated container may be vacuum-insulated.

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.
