Abstract: A fluid cartridge system and method of removing a closure assembly from a first cartridge and a second cartridge includes a first cartridge body and a second cartridge body. A neck projects from the first cartridge body with a first outlet of the first cartridge and a second outlet of the second cartridge. A first closure having a first plug is received within the first outlet and includes a first closure coupling element. In addition, a second closure having a second plug is received within the second outlet and includes a second closure coupling element. The first closure coupling element is configured to interlock with the second closure coupling element such that securing the first cartridge body against the second cartridge body also connects the first closure to the second closure. As such, the first and second closures form the closure assembly for being collectively removed by an operator.

Abstract: A side by side cartridge assembly for dispensing first and second fluid materials includes a first cartridge container and a second cartridge container. The cartridge containers include respective bodies and nozzle members coupled with the bodies. The cartridge containers are positionable with respect to one another such that the two nozzle members cooperate to form a cartridge outlet for dispensing first and second fluid materials from the respective bodies. The cartridge outlet includes dispensing openings communicating with respective nozzle channels, and a sealing surface configured for sealing engagement with a mixing element when a mixing element is attached to the cartridge outlet.

Abstract: An applicator for dispensing a first viscous fluid includes a support structure, a cartridge including a first wall and a first interior space. The first interior space receives a first collapsible tube holding the first viscous fluid. The first collapsible tube is formed from a flexible material and has a length with generally opposite sidewall portions defined along the length. The first collapsible tube is positioned against the first wall and further includes a closed end and a dispensing end. An actuator is operatively coupled to the support structure and moves through the interior space of the cartridge along the length of the collapsible tube and against one of the generally opposite sidewall portions to compress the one generally opposite sidewall portion against the other sidewall portion along the length and squeeze the viscous fluid from the dispensing end.

Abstract: A fluid dispensing assembly is adapted to dispense fluid from a container. The fluid dispensing assembly includes a manifold configured for receiving the container, a piercing member slidably coupled with the manifold, and a nozzle configured to be attached with the manifold, and to engage the piercing member and move the piercing member into piercing engagement with the container.

Abstract: A fluid dispenser and a method for using the fluid dispenser with a syringe barrel holding a fluid including a distribution of composite materials. The fluid dispenser includes a dispensing valve operable to dispense the fluid and a coupling for fluidly connecting the syringe barrel to the dispensing valve. The fluid dispenser also includes a support frame for rotatably supporting the syringe barrel and a motorized drive unit configured to rotate the syringe barrel. The syringe barrel rotates via the motorized drive unit to distribute the composite materials uniformly within the fluid for dispensing the fluid.

Abstract: A fluid cartridge for storing and dispensing first and second fluids includes a first tubular cartridge wall and a second tubular cartridge wall in side-by-side relation. First and second pistons are coupled for movement by a coupling portion and are respectively disposed within the first and second tubular cartridge walls to define first and second side-by-side fluid chambers. A fixed wall is disposed between the first and second fluid chambers. A force is applied to the first piston along the first central longitudinal axis of the first tubular cartridge wall and moves both the first and second pistons along and within the first and second fluid chambers as the coupling portion between the first and second pistons travels within an opening in the fixed wall. The opening may be a preformed slot or may be formed by a cutting element attached with the pistons as the pistons move during the dispensing operation.

Abstract: An adapter for a dispensing device is adapted to couple an actuator to a syringe including an elongate body and a flange. The adapter includes a housing including a proximal end wall, a distal end wall, and a side wall. The adapter includes first and second slots extending inwardly from the side wall, each slot defining at least one of differing shapes and differing sizes. The first and second slots may be at least partially coextensive or may be separated by a divider wall. The first and second slots may be shaped to couple with circular flanges, flanges with flats, or flanges including finger grip portions. Thus, the adapter may couple various syringes to the actuator.

Abstract: Pistons for use in a dispensing cartridge, as well as cartridge systems including such pistons. The piston may include a body having a generally cylindrical configuration with a sidewall and a sealing lip extending outwardly from the sidewall. The sealing lip has a first portion dimensioned to have a first flexibility, a second portion dimensioned to have a second flexibility greater than the first flexibility, a sealing edge terminating the second portion, and a sealing bead positioned between the first portion and the sealing edge of the second portion, and the second portion configured to deflect relative to the first portion such that the sealing edge and the sealing bead have a contacting relationship with an inner wall of the cartridge when the piston is inserted into the cartridge. The sealing edge and sealing bead cooperate to prevent leakage during storage and to prevent blow-by during use.

Abstract: A dispensing cartridge with a vented piston is disclosed. The piston includes a piston shell and a bleed plug. The arrangement of the piston shell and the bleed plug allows air to be vented through the piston until all of the air is vented out of the dispensing cartridge. With the air vented out of the dispensing cartridge, the piston self-into actuates into a closed sealed position in which the bleed plug forms a seal with the piston shell to prevent further fluid from flowing between the two elements.

Abstract: A dual fluid cartridge assembly (30) is adapted to be used with a conventional caulking gun (20). The dual fluid cartridge assembly includes an outer cartridge (32), a piston seal and delivery tube (36), an upper piston seal (38) and an inner cartridge (34). The outer cartridge includes a cartridge outlet (40) for dispensing fluids and as configured to accept conventional mixing nozzles. Fluids are back-filled through the cartridge outlet into the inner cartridge and the outer cartridges. In order to prevent trapped air pockets during the filling of the fluid in the inner cartridge, one or more slots (54) are formed in a base plate (42) of the inner cartridge.

Abstract: A dual fluid cartridge which reduces fluid waste while minimally increasing back pressure is disclosed. One embodiment of the dual fluid cartridge disclosed includes a post having a groove formed therein which allows more fluid to be dispensed from the dual fluid cartridge while simultaneously keeping the increase in back pressure within ranges still suitable for handheld cartridge applications.

Abstract: A propellant actuated dual fluid cartridge which does not need a separate dispensing mechanism is disclosed.
