Abstract
Abstract Dispenser apparatus for multicomponent products comprises a pair of dispensing valves and a manually graspable support bracket. A valve-supporting assembly, mounted on the bracket and substantially defining the posterior portion of the apparatus, attaches the valves to the bracket and includes a pair of rearwardly extending tubular inlet members for connection to a remotely located product supply container. The apparatus further includes a dispensing nozzle unit spaced apart from the dispensing valves, and tubing connecting each of the dispensing valves with the latter unit. A linkable plate connects a manual trigger to each of the dispensing valves for actuation of the valves in unison.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
Dispenser apparatus comprising: manually graspable bracket means; first and second dispensing valve means, each including a tiltable valve element; a valve-supporting assembly attaching said dispensing valve means to said bracket means and including a first pair of tubular connector means adapted for cooperating in establishing a fluid pathway between said dispensing valve means and remote supply container means, said valve-supporting assembly being mounted on said bracket means in braced, fixed position; mixing and dispensing nozzle means spaced apart from said dispensing valve means and including a second pair of tubular connector means; tubing means cooperating in joining said second pair of tubular connector means with said dispensing valve means; manual trigger means; and fixture means rigidly interconnecting said valve elements for actuation thereof in unison and including mounting site means for said trigger means whereby retraction of said trigger means tiltably actuates said dispensing valve means.
