Abstract
A device for packaging and dispensing a generally fluid product includes a dispensing head placed on top of an external body into which is inserted an internal container that forms a reservoir and is suitable for rigid attachment to a metering assembly of the head. The metering assembly, of the airless type, includes a metering pump that is surrounded and supported by a closing element in direct contact with the upper end of the container in a leaktight annular connection area. A ring which surrounds the connection area covers an internal peripheral volume defined between the body and the container. A wall that is movable towards the pump inlet provides a leaktight separation and maintains an identical pressure between the product in the reservoir and the air in the peripheral volume.
