A peripherally defined resilient ampule for storage and dispersement of encapsulated material provides a rearward cylinder-like reservoir body communicating through a transition element to a forwardly extending tapering spout defining a geometrically similar channel therethrough to a sealed tip to create an enclosed containment chamber. The forward portion of the spout may be angulated relative to the body axis. The ampule is formed of resiliently deformable thermal plastic that is configurationally sustaining, but manually deformable for expression of contained material. The spout may be severed at selected axial positions to determine orifice size and configuration and may carry ancillary dispersement devices. A forming process is disclosed to form the ampule from a molded blank of thermal plastic material by thermally activating and drawing the spout, optionally angulating the forward spout portion and sealing the forward spout end.
