Dual collapsible tube dispensing assembly

U.S. Patent Number: 5386928

Abstract: A system for dispensing materials made of two components includes a side-by-side pair of collapsible tubes that fit within a barrel of a pressurized air applicator. As air is admitted into the barrel, the tubes simultaneously collapse to direct components in the tubes through outlet ports and into a static mixer where the components are mixed to a homogeneous mass. Each tube includes a relatively rigid front and rear end piece, and the end pieces are coupled together by pin elements for ease of handling and to facilitate dispensing.
