Abstract
An improved dispenser for cosmetic stick solids such as deodorants constructed to be filled in either normal or inverted position. This dispenser is cylindrical having walls of substantially uniform diameter, an open top, and substantially closed bottom. The dispenser is constructed so that the dispensing means is either pushed up manually, or propelled by a screw-mechanism. In the latter case a long screw is mounted in a central opening in the bottom, and continues along the axis of the cylinder. The cap of the dispenser may assume either of two forms, a snap-on type, or a screw-on type, each exhibiting an air-tight seal. The snap-cap is constructed to include a plurality of cams which operate in conjunction with similar members on the mouth of the cylindrical container to provide relative ease in opening and closing the snap-cap. The dispenser is designed to be filled in a conventional manner from the opening in the top, or, alternatively, from a hole in the bottom of the cylindrical container. In the latter case an inside liner disposed between the cap and the mouth of the cylindrical container retains the product during the filling process.
