A tube assembly is disclosed. The tube assembly may include a tube with an outer diameter and an inner diameter. The tube may have a cylindrical shape. The tube assembly may also include a top integrally formed with the tube such that the tube and the top are a monolithic structure. The top may include an outer lid, a cap with a cap pull tab protruding outwards from the tube assembly, and a breakable portion disposed between the cap and the outer lid. The breakable portion may be configured to be relatively structurally weaker than surrounding areas to allow for breaking off and separating completely the cap at the breakable portion.

An intermediate element for a metal beverage can, for carbonated drinks, where the intermediate element has a shut-off valve and is to be attached to the can end of the can shielding the can end from the interior of the can.

Apparatus and associated methods relate to a can end having guidance features to automatically guide a reusable dispensing body to engage a predetermined region of the can end. In an illustrative example, an auto-interfacing can end (AICE) may include a structural rib disposed inward from an outer rim of the AICE. The outer rim, for example, may define a continuous top surface configured to engage a dispensing body. The continuous top surface also includes a predetermined aperture at a center region. In some implementations, the structural rib may include a vertical displacement perpendicular to a horizontal plane of the continuous top surface. For example, a score of the AICE may include check slots configured to facilitate formation of the predetermined aperture. Various embodiments may advantageously self-align the reusable dispensing body to the center of the continuous top surface when the reusable dispensing body is advancing towards the can end.
