A dispenser package for dispensing dual viscous products which are separately retained within the package and merged at a dispensing nozzle. The dispensing package comprises a container having a compressible portion and a hanger and pouch assembly of plastic material suspended in the container. The hanger has an upper portion with a pair of openings. A flexible film pouch having an opening is bonded in each opening in the hanger and has portions bonded to the hanger. The hanger has lower portions comprising of spaced flexible walls associated with each pouch. The head assembly includes a one-way valve associated with each opening in the hanger and a portion which maintains the viscous products from each of the pouches separate until they pass from a nozzle on the head assembly to the exterior when the compressible portion of the container is squeezed. An atmospheric valve is provided for equalizing the pressure after the compressible portion of the container has been released and the hanger and pouch assembly returns to its original position.

[ What is claimed is:] [1.]1. A dispensing package for dispensing dual viscous products which are separately retained within the package and are merged after passing through a dispensing nozzle comprisinga body having a compressible portion having an open end,a hanger and pouch assembly comprising a hanger suspended in the open end of said body and supporting at least two pouches of flexible material, each having an open end and a closed end,said hanger having flexible walls extending along a portion of said pouches,a head assembly comprising a collar and a manifold,said collar being removably positioned on the open end of said body,said manifold being interposed between said collar and said hanger and pouch assembly,said manifold including means defining first and second chambers communicating with each pouch and means defining a nozzle with second chambers communicating with said first chambers such that the products will not merge until after passage from said nozzle,a one-way valve associated with said chambers such that the product will flow from each pouch when the body is squeezed, andan equalizing valve mounted on said package to permit air to flow between the body and pouches and equalize the pressure when the squeeze pressure is released.
