Dispensing and applicator devices

Abstract

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.
