Storage and dispensing device for a liquid product

摘要

The packaging and dispensing unit comprises a closed product reservoir (2) composed of a variable volume one end of which is closed by a rigid base (16). The base has a transverse bottom passed through by a channel (18) integral with the base. A pump (26) placed in the channel communicates with the reservoir. The channel internal wall comprises an annular seal (18d) able to permanently deform radially in a zone (28) of the pump in order to immobilize the pump in the channel. In addition there is a pushbutton (34) provided with a dispensing orifice (38) communicating with the pump rod (32).
