A multipurpose filament dispensing device serves the dual purpose of dispensing a filament, such as dental floss, while simultaneously forming a cap on a container of a topical composition. The device can either function as a standalone dispenser for storing and dispensing the filament, or serve as a cap for the container while simultaneously storing and dispensing the filament. The filament is rotatably extracted from an internal spool. The device dispenses a desired amount of filament from the spool, extending the filament from a raised outlet to a depressed cutting member. The downward slope of the filament facilitates grasping and manipulating of the filament. After extracting a desired unit length of the filament, the filament may be cut at a unit length with a sharp edge on the cutting member. The device forms a detachable cap over a container of topical composition, such as lip balm.
