Abstract:
1. A system for connecting a dispenser head having a body structure to a liquid container having a threaded neck and a longitudinal axis, said system comprising: a base area on the body structure, facing the neck of the container; an intermediate body positioned between the base area of the structure and the neck of the container, said intermediate body having an annular seat which accommodates the base area, a flange firmly screwed to the neck of the container, wherein unscrewing occurs by applying an unscrewing torque, wherein the flange comprises an annular lip which engages the base area of the body structure binding it axially to the same; whereby free rotation of the flange is prevented by a torque resistant to rotation developed by contact between the intermediate body and the base area of the body structure; and wherein the torque resistant to rotation is less than the unscrewing torque, to permit accidental rotation of the head without unscrewing the flange, the annular lip of the flange presses the intermediate body towards the neck and the base area into the annular seat of the intermediate body and the intermediate body comprises an outer defining wall, radially positioned outside the base area, and on which the annular lip acts, and the annular lip has an inward radial extension extending beyond the outer defining wall to also engage the base area.
