Abstract

An elongate peripherally defined ampule having a handle-like reservoir structurally communicating with a medial articulating element which interconnects an elongate spout to define an enclosed containment chamber. The ampule is formed of resiliently deformable material to allow dispersement of contents by manual deformation of the ampule structure and to allow accurate placement of expressed contents by manipulation of the articulating element and spout structure. The spout provides a relatively small end portion and an outwardly tapering medial channel for severance at selected positions to provide dispersement orifices of different sizes and shapes. The ampule defines a containment chamber of up to the two cubic centimeter volume range for dispersement of extrudable materials of a fluidic, gelatinous, or powdered nature, and especially for pre-measured single use quantities of chemicals, medicaments and the like. The ampule is preferably formed by molding polymeric or resinous plastic materials.
