Dispensing and applicator devices of the present invention provide delivery and application of a desired composition, generally in a
single application volume and dosage, to a desired application location or surface. The devices generally comprise a combination of a flexible reservoir that is fillable or pre-filled with a treatment composition and an applicator component that accesses the treatment composition in the reservoir and delivers it to a desired
tissue surface through a porous applicator. The reservoir and applicator components, and the treatment composition, may be sterilized and packaged in sterile format, or may be packaged to meet other “clean” or “sanitary” specifications short of
sterility. Many uses are described, including applications of various compositions, including
cosmetics,
oral hygiene compositions, treatment agents and other substances to
skin and tissue surfaces; industrial and household applications involving compositions such as cleaning agents, bonding agents, and the like to various types of surfaces, and food service applications involving compositions such as condiments, oils, and the like.
