ABSTRACT:
The new invention allows for easy retrieval of fall backs and eases the initial threading process upon initial opening/use of the package. Threading is done without removing the cap. Several of the embodiments allow refills to be inserted into the canister without removing the lid/cap. The layout of the dispensing system and the geometry and shape of the dispensing orifice/aperture minimize and mitigate product fall backs. The new invention improves performance of the orifices/apertures through unique geometry and shape as well as using different materials from existing products or the combination of multiple materials. Varying orifice diameter, co-molded density and stiffness or geometry of the actual lobes defining the dispensing aperture allows the precise amount of friction to be created in the dispensing opening for selectively grabbing or releasing the towelette, thereby tearing the towelette connecting perforations at just the right time.
