Dispensing container for multi-component curable compositions

A system for storing, initiating curing of and dispensing a multicomponent curable material having at least two components capable of interreacting upon being mixed together, said system comprising:

• container means for storing both of said components;
• outlet means on said container means including a spray head for discharging a curable material formed upon mixing of said components;
• means defining an internal space within said container means within which said components are mixed to form said mixture upstream of said outlet means, one of said components being present in said container means in a form of globules surrounded by respective destructible layers of a substance which is nonreactive with said components and which layers are in contact with the other of said component;
• means for applying pressure to said components to cause said components to flow toward said outlet means;
• at least one screen element in said container means encountered by said components as said components pass under pressure through said space to said outlet means for intercepting said globules and effecting rupture of said layers at at least a minimum of said pressure to enable said globules to mix with said other component in said space and form the mixture passing to said outlet means, said screen element having apertures configured to block passage of whole globules surrounded by intact layers of said substance but passing said one of said components from disrupted globules;
• and
• conduit means connecting said head with said space and defining a flow path for said material.

• outlet means on said container means for discharging a curable material formed upon mixing of said components;
• means defining an internal space within said container means within which said components are mixed to form said mixture upstream of said outlet means, one of said components being present in said container means entirely in a form of a multiplicity of discrete units of said one of said components surrounded by respective destructible layers of a substance which is nonreactive with said components and which layers are in contact with the other of said components forming a continuous phase in which said units are distributed within said container means;
• means for applying pressure to said components to cause said components to flow toward said outlet means;
• and
• means in said container means and encountered by said components as said components pass under pressure through said space to said outlet means for destroying said layers to enable said units to mix with said other component in said space and form the mixture passing to said outlet means.
