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.

A two-end-through vacuum heat-insulated container outer tube sealing structure includes a vacuum heat-insulated container outer tube, where a shoulder part of the vacuum heat-insulated container outer tube is provided with a plane; a vacuum cavity is formed in the plane; a vacuum hole for vacuum pumping is formed in the vacuum cavity; the vacuum cavity is filled with a sealing material; a side surface of the plane of the shoulder part is provided with a circular step from top to bottom; a shielding cover is subjected to primary welding on the circular step; a weld bead of the welding is removed by polishing; the shielding cover and the circular step are in gap-free fit; the other end of the shielding cover is subjected to secondary welding with a mouth part of a bottle body; and the weld bead of the welding is removed by sanding the mouth.

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 stainless steel food service vessel is configured to provide an insulating carrier containing a food item or beverage. The stainless steel vessel is formed of a double wall construction having a sealed insulating cavity defined between the walls of the vessel. The insulating cavity may contain an insulating fluid or may be evacuated under a vacuum to impart superior insulating properties to the vessel to keep food items or beverages hot or cold.

A shock-proof mineral container and mounting structure thereof, which provides a heat insulation container with a liner formed using mineral material. The liner is provided with shock-proof protection and a mounted assembly structure. During the process of assembling the single ended suspended configuration, a blocking member having an elastic effect is inter-connected between an annular neck configured on the mineral liner and an upper link opening joined to an outer cylinder, and the elastic strain of the blocking member is used to absorb shock waves occasionally produced by an external force when carrying the container, thereby safeguarding the structural safety of the hard and brittle mineral liner. In addition, the structure is supplemented with a cylinder liner, which adds to the heat insulation capacity of the container and maintains the stability of the mineral liner.

A thermos cup vacuumizing device and method are provided. The thermos cup vacuumizing device includes a pre-vacuumizing chamber, a heating chamber, a welding chamber, and a cooling chamber. A continuous conveying device is provided at a bottom of each of the chambers. The thermos cup vacuumizing device further includes a controllable and movable laser welding device and multiple transparent windows. A laser beam of the laser welding device passes through the transparent windows to melt a welding ball at provided at a hole in the center of the bottom of the thermos cup. A vertically movable inlet valve is provided at an inlet of the pre-vacuumizing chamber, and a vertically movable outlet valve is provided at an outlet of the cooling chamber. The present disclosure realizes the continuous vacuumizing operation on the thermos cups, improves the product qualification rate and processing efficiency, and realizes automatic mass production.

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.
