40 of the anchor member 38 as shown the tube 30 is flexible and is deformed as it engages the anchor member 38 still referring to fig2 it can be seen that the distal end 46 of the anchor member 38 also forms a threaded bore 56 and protrusion 58 that define a cylindrical void 60 as shown the inlet 18 of the first reservoir member 12 is received within the cylindrical void 60 in order to ensure a fluid tight engagement the inlet 18 is provided with tabs 62 that extend radially outward to engage with the threaded bore 56 the first reservoir member 12 also includes radially outward extending threads 64 at its distal end 66 further the second reservoir member 14 includes reciprocating radially inward extending threads 68 at its proximal end 70 with this cooperation of structure the reservoir members 12 14 may be connected and disconnected in fig2 the outlet 20 of the second reservoir member 14 is shown in engagement with the tube 30 specifically the outlet 20 is fit inside the tube 30 to frictionally engage the second reservoir member 14 and the tube 30 and provide fluid communication between the chamber 16 and the lumen 71 of the tube 30 because the tube 30 is flexible it can deform to engage the outlet 20 when the lumen 42 channel 40 chamber 16 and lumen 71 are interconnected a passageway 72 from the fluid source 22 to the nozzle 28 both shown in fig1 is created further when the reservoir members 12 14 are connected.
