The present invention relates to improved product dispensers for various spreadable products, including fluids, suspensions, lotions, creams, emulsions, and gels. In a preferred embodiment of the present invention, the dispenser is in the form of an improved roll-on type applicator with an enlarged application/distribution surface in the form of a dome with an aperture for exposing a portion of the rotating element. As product is expressed from the gap between the element and dome, it follows the surface of the element into contact with the desired surface and is thereby applied to this surface. Excess product not applied to the desired surface by the element either follows the element surface through the gap between the element and the dome back into the container or is sheared from the element surface by the edge of the aperture in the dome. This sheared-off product flows onto the dome surface or contacts other pans of the desired receiving surface and is distributed by the application/distribution surface of the dome, which functions both as a secondary applicator for this undistributed product and as a primary distributor for evening out the total product distribution on the desired surface, thus providing an improved means of uniformly applying and distributing product dispensed by the rotating element. The resulting roll-on applicator enables the product to be more easily applied in a consistent, less messy fashion, and the simplicity of the package construction equates to a very user-friendly package which is cost effective to produce and reliable in operation. |
