An apparatus having a bottom assembly for interfacing to connect the bottom assembly to a second structure, having a deformable element that, when sufficient force is applied via the process of attaching the bottom assembly to the second structure, and at an appropriate value of axial compression or pressure, passes from a stable state, through a rapid shape transformation to a second state via a regime of reduced resistance to deformation, creating a tactile or audible indication that the apparatus has been properly installed. The deformable element may be joined to the apparatus using a circumferential insertion ring by friction fit or spring fit, may be inserted inwardly of a sealing surface and may adhere magnetically to the second structure to facilitate installation.
