container 112 is suctioned up through dip tube 125 the liquid then enters the hollow circular projection 183 of the fluid exit port 182 of the container adapter 170 and the liquid then exits the flow holes 185 of the fluid exit port 182 the liquid continues through the flow conduit 166 of the sprayer connector 150 and then enters the sprayer the mating dimensions of the sprayer connector 150 and the container adapter 170 also provide keying structures that ensure that only refills containing a liquid appropriate for a particular purpose are used with the sprayer specifically a tight fit is required between the sprayer connector 150 and the container adapter 170 so that the sprayer may be primed with liquid by way of the dip tube 125 if air leakage were to occur the sprayer would suck air into the sprayer rather than liquid therefore only refills comprising a container 112 with an attached container adapter 170 that mates with the sprayer connector 150 of the sprayer would be suitable for use with the container 112 thus the present invention provides a device that that places an interior space of a fluid container in fluid communication with a sprayer and that provides a keying structure such that only refill containers having a liquid appropriate for a particular purpose are used with the sprayer although the present invention has been described in detail with reference to certain embodiments one skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments which have been.
