摘要:
A fluid cartridge (12) for storing and dispensing first and second fluids (80, 82) includes a first tubular cartridge wall and a second tubular cartridge wall in side-by-side relation. First and second pistons (52, 52) are coupled for movement by a coupling portion (56) and are respectively disposed within the first and second tubular cartridge walls (30, 32) to define first and second side-by-side fluid chambers (84, 86). A fixed wal (58) 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 is formed by a cutting element (70) attached with the pistons as the pistons move during the dispensing operation.
摘要:
An applicator (10) for dispensing a first viscous fluid includes a support structure (18), a cartridge (14) including a first wall (38) and a first interior space (42). The first interior space (42) receives a first collapsible tube (40) holding the first viscous fluid. The first collapsible tube (40) 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 (38) and further includes a closed end (50) and a dispensing end (48). An actuator (20) is operatively coupled to the support structure (18) and moves through the interior space (42) of the cartridge (14) 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 (48).
