Patent attributes
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.
