First Claim
1. An apparatus for storing and mixing componnts for forming a product and dispensing the resultant product, said apparatus comprising:
- a dispensing head;
a first cartridge for storing a second fluid component;
a second cartridge for storing a second fluid component, both said first and said second cartridges having a first open end and a second closed end;
a first manually actuated distributor providing fluid communication between said first cartridge open end and said dispensing head;
said second manually actuated distributor providing fluid communication between said second cartridge open end and said dispensing head, both said first and said second distributors having a preselected effective stroke distance;
a compensating assembly for modifying the stroke of one distributor relative to the other; and
a housing for maintaining, respectively, said dispensing head, first cartridge, second cartridge, first distributor, second distributor, and compensating assembly in operative relation with each other;
whereby upon movement of said dispensing head and said housing toward each other, said compensating assembly will yield to reduce the effective stroke distance of said first distributor;
whereby said first component and said second component are mixed in a preselected proportion within said dispensing head to form a resultant product and said resultant product is subsequently discharged from said dispensing head.

Abstract
An apparatus and method for storing and mixing components for forming a product and dispensing the resultant product. The apparatus comprises a dispensing head, a first cartridge for storing a first fluid component, and a second cartridge for storing a second fluid component. The first cartridge and the second cartridge each have a first open end and a second closed end. A first distributor provides fluid communication between the first cartridge and the dispensing head, and a second distributor provides fluid communication between the second cartridge and the dispensing head. Both the first and second distributors have a preselected effective stroke distance. A compensating assembly is also provided. A housing maintains the dispensing head, first cartridge, second cartridge, first distributor, second distributor, and compensating assembly in operative relation with each other. Upon movement of the dispensing head and housing toward each other, the compensating assembly will yield to reduce the stroke of the first distributor. Thus, the firt component and the second component are mixed in a preselected proportion within the dispensing head to form a resultant product and the product is subsequently discharged from the dispensing head.

22. An apparatus for storing and mixing components for forming a product and dispensing the resultant product, said apparatus comprising:
-
a dispensing head; a first cartridge for storing a second fluid component; a second cartridge for storing a second fluid component, both said first and said second cartridges having a first open end and a second closed end; a first distributor providing fluid communication between said first cartridge open end and said dispensing head; a second distributor providing fluid communication between said second cartridge open end and said dispensing head, both said first and said second distributors having a preselected effective stroke distance; a compensating assembly for modifying teh stroke of one pump relative to the other; and a housing for maintaining, respectively, said dispensing head, first cartridge, second cartridge, first distributor, second distributor, and compensating assembly in operative relation with each other; whereby upon movement of said dispensing head and said housing toward each other, said compensating assembly first causes said second component to be discharged into said dispensing head, and then causes said first component to be discharges into said dispensing head; whereby said first component and said second component are mixed in a preselected proportion for a preselected duration in said dispensing head and subsequently discharged from said dispensing head.

23. An apparatus for storing and mixing components for forming a product and dispensing the resultant product, said apparatus comprising:
-
a dispensing head; a first cartridge for storing a second fluid component; a second cartridge for storing a second fluid component, both said first and said second cartridges having a first open end and a second closed end; a first pump providing fluid communication between said first cartridge open end and said dispensing head; a second pump providing fluid communication between said second cartridge open end and said dispensing head, both said first and said second distributors having a preselected effective stroke distance; a compensating assembly for modifying the stroke of one pump relative to the other; and a housing for maintaining, respectively, said dispensing head, first cartridge, second cartridge, first pump, second pump, and compensating assembly in operative relation with each other; whereby upon the application of a compressive force to move said dispensing head and said housing toward each other, said compensating assembly will yield, thereby adjusting the effective stroke distance of said first pump and said second pump, whereby said first component and said second component are mixed in preselected proportions within said dispensing head to form a resultant product and said resultant product is subsequently discharged from said dispensing head.

24. A method for storing and mixing components for forming a product and dispensing the resultant product thus produced, said method comprising:
-
at least partially filling a first cartridge with a first fluid component; at least partially fililng a second cartridge with a second fluid component; attaching a first distributor to said first cartridge, said first distributor comprising a first spring and having a first preselected effective stroke distance; attaching a second distributor to said second cartridge, said second distributor comprising a second spring and having a second preselected effective stroke distance; positioning said first cartridge and said second cartridge within a housing in abutting relation with a compensating assembly located therein, wherein said compensating assembly comprises a lever positioned on a fulcrum offset from the center of said lever, thereby providing said lever with a longer lever arm and a shorter lever arm; enclosing said first cartridge, said second cartridge, said first distributor, said second distributor, and said compensating assembly within said housing with a dispensing head; applying a compressive force to move said dispensing head and housing toward each other, thereby causing said shorter lever arm to first cause said second distributor to discharge a preselected amount of said second component into said dispensing head, and then causing said longer lever arm to cause said first distributor to discharge a preselected amount of said first component into said dispensing head; wherein said first component and said second component are thereby discharged in a preselected proportion for a preselected duration into said dispensing head to form a resultant product which is subsequently discharged from said dispensing head. - View Dependent Claims (25, 26, 27, 28, 29)
