The assembly comprises a sealing collar having a resilient deformable body having a central aperture for receiving the dispensing means, such as a pump. The body includes in its periphery a circular sealing ring having an annular outer sidewall which includes a wedge-shaped tapered sealing member. The tapered surface has a diameter progressively increasing over a range which encompasses the sidewall diameter when the sealing member is mounted on the flange, the tapered surface is driven into contact with the bottle flange sidewall to provide a liquid and airtight seal between the tapered flange and the container flange. A mounting cup have a central aperture for receiving the dispensing means, forces the tapered surface into contact with the container flange.
