Embodiments, described herein relate generally to devices, systems, apparatus, and methods for producing lubricious surfaces that increase the ease of communication of viscous liquids across the same. The apparatus can include a container having an inner surface and a lubricating liquid disposed on a surface, the lubricating liquid including a surfactant. In some embodiments, a sprayer hub can rotate about a center axis and deliver the lubricating liquid to the inner surface. In some embodiments, a contact liquid can fill at least a portion of the container. In some embodiments, the surfactant can be an amphiphilic molecule that is substantially immiscible with the lubricating liquid and at least partially miscible with the contact liquid. In some embodiments, the surfactant can form a barrier at an interface between the lubricating liquid and the contact liquid.

A pre-form assembly to make a container (110) for beverages comprises an external pre-form (12) and an internal pre-form (14), each configured to form respectively an external drum (112) and an internal bag (114) of the container (110). The internal pre-form (14) is associable internally with the external pre¬form (12) so as to define with the external pre-form (12) a hollow space (13), and the internal (14) and external (12) pre-forms comprise respective coupling members (30, 34, 38) in correspondence with respective neck portions (22, 26) suitable to reciprocally position the external pre-form (12) and the internal pre-form (14) along a longitudinal axis (X).

A double container includes: an outer layer body including an outer mouth portion and a barrel portion; an inner layer body including an inner mouth portion and a containing portion; an outside air introduction port for introducing outside air; and a plurality of vertical ribs arranged with spacing in a circumferential direction on an inner surface of the outer layer body or an outer surface of the inner layer body, and each extending over the outer mouth portion to the shoulder portion or extending over the inner mouth portion to the containing portion, wherein at least one of the plurality of vertical ribs faces the outside air introduction port.

An improved metal or glass container is described. The metal or glass container includes a body portion and an end closure. The end closure includes a laminated polymer film attached to the product facing side of the end closure. When the container is sealed, the laminated polymer film attached to the product facing side of the end closure forms a liner.
