Abstract

Abstract A compact, portable pocket flask for cleaning and refreshing dentures. The flask is elongated, elliptically-shaped and pocket sized and contains two completely sealed compartments also sealed from each other. One such compartment is shaped to carry a denture for cleaning purposes, and is accessible through inverting of the flask and removing the cup portion which seals the fluid in the lower compartment. This lower flask compartment has padded walls, and is completely sealed by means of said cup portion, whereby the denture within the compartment may be treated by shaking the flask. The other compartment is connected to the neck of the flask and may contain rinsing fluid such as mouthwash or water; or by means of the sealing "cup" enables transfer of fluid from the upper compartment to the lower compartment.
