Abstract (en)
[origin: EP0307310A1] In order to facilitate the introduction of a propelling gas into a container equipped with a precompression pump of the type in which the closure of a pump chamber is obtained by fitting two cylinders (11, 15) into each other, one cylinder (11) carrying a sealing lip (12), a relief (18) is provided on the other cylinder so that, when it reaches this level, the sealing lip no longer has a sealing effect. In this arrangement, the propelling gas can then easily traverse the pump. <IMAGE>
