Applicator system for extrusive dispensing of work material from collapsible cartridge

An applicator system for dispensing of material from flexible pre-charged sections of a cartridge unit, the system comprising:

• a housing portion including:
• a cartridge bay defining a plurality of containment members respectively defining a plurality of containment compartments, each containment compartment defining a chamber extending about a longitudinal axis from a containment opening at a terminal end of said cartridge bay, each chamber being configured to receive through the containment opening one flexible pre-charged section of the cartridge unit in a direction substantially parallel to the longitudinal axis and substantially enclose the flexible pre-charged section of a cartridge unit in substantially conformed manner therein, at least one of said containment members being removably disposed, the cartridge unit having a dispensing cap forming a mixer head and a plurality of the pre-charged sections extending therefrom;
• and,
• a retention structure disposed detachably at the terminal end of said cartridge bay forward of said cartridge bay, said retention structure being configured to transition between an open configuration and a closed configuration to releasably retain the cartridge unit against forward escape from said cartridge bay, wherein in the closed configuration, the retention structure extends across the containment opening of each containment compartment, said retention structure defining a notched passage to receive an elongate dispensing tip portion of the cartridge unit therethrough such that the cartridge unit extends from the plurality of containment compartments through the notched passage of the retention structure;
• an actuator portion coupled to said housing portion in communication with said cartridge bay, said actuator portion including a plurality of drive members each engaging one of the flexible pre-charged sections of the cartridge unit within one of said containment compartment;
• and,
• an activation member coupled to said actuator portion to selectively activate displacement of said drive members within said containment compartments responsive to user manipulation, said drive members being selectively driven thereby to compress the flexible pre-charged sections in a forward direction along and in direct contact with surrounding inner surfaces of respective containment compartments toward said retention structure.

• a body portion having an actuator portion and a housing portion coupled thereto;
• said housing portion including:
• a cartridge bay defining a plurality of removably disposed containment members respectively defining a plurality of containment compartments, each containment compartment defining a chamber extending about a longitudinal axis from a containment opening at a terminal end of said cartridge bay, each of said containment compartments being configured to receive one pre-charged portion of a cartridge unit through the containment opening in a direction substantially parallel to the longitudinal axis in substantially conformed manner therein, each of said containment members having a tubular structure forming a contiguous cylindrical inner wall surface about one said containment compartment, the cartridge unit having a dispensing cap forming a mixer head and a plurality of the pre-charged portions extending therefrom;
• a retention structure disposed detachably at a terminal end region of said cartridge bay forward of said cartridge bay, said retention structure being configured to transition between an open configuration and a closed configuration to releasably retain the cartridge unit against forward escape from said cartridge bay, wherein in the closed configuration, the retention structure extends across the containment opening of each containment compartment, said retention structure defining a notched passage to receive an elongate dispensing tip portion of the cartridge unit therethrough such that the cartridge unit extends from the plurality of containment compartments through the notched passage of the retention structure;
• and,
• said actuator portion being coupled to said housing portion in communication with said cartridge bay, said actuator portion including a plurality of drive members respectively engaging the pre-charged portions of the cartridge unit respectively within said containment compartments;
• wherein a handle and an activation member are coupled to said body portion, said activation member being coupled to said actuator portion to selectively activate displacement of said drive members within said containment compartments responsive to user manipulation, said drive members being selectively driven thereby to compress the pre-charged portions of the cartridge unit within said containment compartments.

• said housing portion including:
• a cartridge bay defining a plurality of removably disposed containment members respectively defining a plurality of containment compartments, each of said containment compartments extending along a longitudinal axis to receive one pre-charged portion of a cartridge unit in substantially conformed manner therein along a direction substantially parallel to the longitudinal axis, each of said containment members having a tubular structure forming a contiguous cylindrical inner wall surface about one said containment compartment, the cartridge unit having a dispensing cap forming a mixer head and a plurality of the pre-charged portions extending therefrom;
• a retention structure disposed at a terminal end region of said cartridge bay forward of said cartridge bay, said retention structure defining a notched passage to receive an elongate dispensing tip portion of the cartridge unit therethrough, said retention structure being configured to block the cartridge unit against forward escape from said cartridge bay;
• and,
• said actuator portion being coupled to said housing portion in communication with said cartridge bay, said actuator portion including a plurality of drive members respectively engaging the pre-charged portions of the cartridge unit respectively within said containment compartments;
• wherein a handle and an activation member are coupled to said body portion, said activation member being coupled to said actuator portion to selectively activate displacement of said drive members within said containment compartments responsive to user manipulation, said drive members being selectively driven thereby to compress the pre-charged portions of the cartridge unit within said containment compartments;
• wherein said housing portion includes:
• a level indicator disposed in displaceable manner over said cartridge bay, said level indicator being displaceable with said driving member to visually indicate the location thereof within said containment compartment;
• and,
• a translucent shield protectively disposed at least partially about said level indicator.
