Abstract
A replacement fluid cartridge for a dispenser has three parts: an injection molded nozzle, a thermoformed reservoir portion, and a cover sheet. The nozzle has a substantially flat top portion, an outer portion adjacent to the flat top portion, an outermost end, and a plurality of orifices extending through the nozzle. The second part is a piece of flexible film having a plurality of depressions surrounded by a flange. The flange is continuous and in a plane except at a nozzle-fitting portion. The nozzle-fitting portion is shaped to wrap around the outer portion of the nozzle where it is bonded to the nozzle in a fluid-tight manner. The flat top portion of the nozzle resides substantially within the plane of the flange. Each of the plurality of depressions has an inside, a continuous sidewall, and a closed bottom. The third part is a substantially flat cover sheet bonded to the flange and to the flat top portion of the nozzle such that the plurality of depressions are sealed closed by the cover sheet. Each of the plurality of orifices in the nozzle provide exclusive fluid communication from the outermost end of the nozzle to one inside of each of the plurality of depressions.
