Viscous fluid dispenser

Abstract

A readily collapsible enclosure holding viscous fluid is housed within a non-elastic housing with relatively rigid members secured on one end and extending on opposite sides of the collapsible enclosure holding viscous fluid within the non-elastic housing so that pressure applied to the rigid members reduces the volume of the enclosure to discharge the viscous fluid. Various pressure applying points and assists are included with spring pressure balancing applications on said rigid members included. A strand dispensing spool can be housed within the resilient housing.
