ABSTRACT:
A device for releasably connecting a generic liquid sprayer, e.g. for detergents and the like, of the type including a pump operated through a trigger-type lever, to the neck portion of a container of the hand-held type. The device has a tubular element provided with a threadway on its inner surface which is releasably engaged, as by threading down, by a sleeve whose inner surface is provided with snap-action members of engagement with counter-members provided on the container neck portion to provide a non-releasable axial coupling. The sleeve enables initial assembly of the device by axial fitting over the container neck portion and recovery of the device by threading out of the sleeve, for later re-use on a re-fill container provided, in turn, with a sleeve, once the original conatiner has been depleted of its contents. In addition, the device enables the delivery nozzle and trigger-type lever of the sprayer to be properly positioned relatively to the container contour, particularly where the latter has an anatomical type of configuration.
