ABSTRACT:
A finger manipulated dispenser of viscous liquids from a flexible tube comprises a smaller diameter hollow reel, called a core, and a larger diameter hollow reel, called a spool, which lengthwise telescope together. Each reel at one end has a large diameter flange serving to receive finger applied rotating forces and to abut the non flanged end of the other reel. Each reel has a longitudinal slot, extending from the respective larger diameter flange to the respective non flanged end, to receive collapsed portions of a flexible tube. The core at the non flanged end is partially radially cut to create a directional control pawl. The spool at the larger diameter flange is notched at several radial locations to receive the directional control pawl, thereby completing a ratchet subassembly. To use, the bottom tube end is longitudinally inserted into the core slot. The spool is aligned, with the longitudinal slots of both the core and the spool, and the core and the spool are telescoped together. After some contents of the tube are squeezed out in the usual fingers of one hand compressing method, on one, two or three occasions, the reels are relatively rotated to wrap emptied flexible tube portions around the core and within the circumferential space between the core and the spool. Unwrapped portions of the flexible tube become full again. An accessory is snapped into alternate positions about the spool, to position the flexible tube upright on a counter, or to hang it from a support.
