Abstract: Apparatus and associated methods relate to a can having a pattern of radial displacement of material of a malleable can end with respect to a longitudinal axis of a malleable can body. In an illustrative example, the can end may sealingly couple to an open end of the longitudinally extending can body by a circumferential seam to form a sealed cavity. A can-opening dispenser may, for example, include at least one radially displaceable element (RDEL) configured such that, when operated into releasable engagement with the radially patterned seam, the dispenser resists rotation relative to the can about the longitudinal axis of the can. The RDEL may, for example, be radially deflected by operation of a collar in a first rotational direction (FRD). Continued operation of the collar in the FRD may, for example, operate an opening member to open the can. Various embodiments may advantageously provide self-opening dispensers for recyclable cans.
