ABSTRACT:
The present invention relates to improved product dispensers for various products, including solids, gels, semi-solids, and other substantially solid products. In a preferred embodiment of the present invention, the dispenser is in the form of an improved twist-up type dispenser with an application/distribution surface in the form of a mesh applicator head for covering the exposed end of a solid stick of product. The dispenser includes a force-limiting mechanism to limit the force exerted by the product on the mesh applicator head during pre-loading to prevent extrusion of the product. The dispenser further includes a force-maintaining mechanism to maintain the surface of the product in continuous intimate contact with the mesh applicator head during the application process. The surface of the product exposed via the apertures is sheared off in conventional fashion, and the mesh provides for a more even distribution of the product than conventional solid stick-type dispensers. The resulting dispenser provides application and distribution properties superior to current solid-stick dispensers and enables the product to be more easily applied in a consistent, less messy fashion.
