A method for making a container includes forming a first cavity of a container by shaping an inner wall so that a first surface of the inner wall defines the first cavity; forming a second cavity of the container by shaping an outer wall so that a third surface of the outer wall surrounds a second surface of the inner wall such that together the third and second surfaces define the second cavity; and connecting the inner and outer walls together. The method then includes forming a hole through the outer wall to expose the second cavity to the outside ambient environment and then applying an enamel coating, while preventing the enamel coating from being deposited in the hole. After the enamel coating is applied, the method includes heating the container to glaze the enamel coating and fix the coating to the one or more surfaces.

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.

An insulated container is described. The insulated container includes a double-walled structure having a closed end, an open end, and a side wall extending between the closed and open ends. The side wall and the closed end of the insulated container together form a hollow interior. A glass structure may be arranged within the hollow interior. The glass structure includes a body having an open upper end and a base end, and a sipping portion extending from the upper end. The sipping portion may include a sipping end and a shoulder end spaced apart from the sipping end. The sipping portion protrudes from the open end of the double-walled structure. A collar is positioned over the sipping portion of the glass structure thereby forming a sipping surface.
