Abstract
Abstract The dispenser, as fabricated predominately of molded plastic parts, includes an outer box-like housing affording a vertically elongated inner space which receives an inverted collapsibly deformable tube whose content is to be downwardly dispensed. The usual threaded tube neck is releasably held upright under a crimping grip exerted thereon by an apertured hold-down plate through which the tube neck extends; and a closure cap pivots vertically on said plate to optionally open and seal the neck''s dispsensing mouth. A slide of inverted U-shape is movable downwardly in the housing space, and vertically spaced pairs of toggle-type hinges are pivoted at their outer ends on uprights of the slide, the pairs facing one another inwardly from their slide pivots. The inner ends of said toggle hinge pairs are pivotally connected at vertically spaced points to a pair of like tubesqueezing plates, so that on downward movement of said slide, said pairs of toggle hinges will straighten downwardly and inwardly in typical toggle fashion. They thus thrust said plates toward one another to expel a desired content of the tube to be dispensed. The squeeze plates are spring biased outwardly in opposition to said compression movement; and the slide, as pivoted to and outwardly of said plates by the toggle hinges, is actuated downwardly for the dispensing action by a knobheaded screw, which screw threads downwardly into a nut part fixed on an upper cross-piece of the slide. The screw is rotatable in and axially restrained at its bottom by a horizontal partition part in the housing and the screw''s knob is downwardly restrained by the top of the housing proper.
