A liquid dispensing container has an outer shell including a wall having an inner surface and an outer surface. An inner core is coupled to the outer shell and has an outer surface and an inner surface that defines a reservoir configured to contain a fluid. The inner core and outer shell cooperatively define a longitudinal axis. A liner is positioned between the outer shell and the inner core. The liner comprises a stretchable material that is in stretched along the longitudinal axis.

An insulated container assembly, comprises a container body, including an inner wall and an outer wall coupled at a top of the container body and separated by a vacuum gap, and a lid that is reversibly attachable to the container body. The lid includes a vacuum insert; and a sleeve encompassing the vacuum insert, the sleeve configured to facilitate attachment of the lid to the container body, and further configured to generate a seal between the vacuum insert and the inner wall of the container body such that a base of the vacuum insert is exposed to a central cavity of the container body when the lid is fully attached to the container body. In this way, the entire central cavity may be surrounded by vacuum insulation, thus improving the thermal properties of the insulated container assembly.

Disclosed is a vacuum compartment structure for a cup lid and a manufacturing method thereof. The vacuum compartment structure for a cup lid includes a stainless steel cylinder body and a compartment upper cover. The compartment upper cover is covered on the cylinder body and has an inwardly recessed shape, and the compartment upper cover and the cylinder body are fixedly connected and sealed by laser welding. The compartment upper cover and the cylinder body form a vacuum chamber, which has a getter therein. The compartment upper cover is arranged with a plastic upper cover layer, an outer surface of the cylinder body is wrapped with a plastic lower cover layer, and the plastic upper cover layer is combined with the plastic lower cover layer to fasten and wrap the compartment upper cover and the cylinder body.

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.

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.

A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston and a second dual-container shaped mould cavity set are provided along with one or more wall stability devices applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded containers, such that the second container side wall(s) may be inverted at least partially inside-out, while at the same time the second container bottom wall at least substantially does not invert, in order for the second container to become a substantially mirror-image inverted second container extending in the same direction as the first container, and an air gap is formed between the first container and second container.

“CONSTRUCTIVE ARRANGEMENT IN A THERMAL CHAMBER FOR THE PRODUCTION OF HOME-MADE YOGHURT”, selectively chosen to be natural or greek, said thermal chamber being comprised of an outer container (casing) (1) provided with its respective lid (2); the said casing (1) embodied by an internal perimeter frame (3) next to its upper edge, which selectively accommodates and supports coaxially an inner container (4) and/or a filter container (6); wherein the inner container (4) has smaller dimensions than the casing (1), in a way that creates between the two structures a free perimeter space that works as an air chamber (5) which act as a thermal insulator to the thermal chamber (1, 2); being that the filter container (6), with slightly smaller dimensions when compared to the inner container (4), tightly fits in the inner container (4), but still with a depth not as profound as in the inner container (4), creating a collector interspace (7) between the bottom walls of both structures; the bottom wall of the filter container (6) is designed with a netting-like surface (6a), through which occurs the drainage of the liquid (serum) created during the processing of the milk volume kept in the thermal chamber, thus defined.
