The pump of the present invention comprises a flexible pump body (2) containing an aspiration mechanism and an embedded rigid sleeve (4) equipped with a ring (6). An annular volume (10) is formed above the aforementioned ring, the dimensions of said volume being large enough so that the pump body (2) can be performed in a substantially curved manner during assembly. The invention is applied to glass bottles. Sovereignty item 1. A pump capable of blocking a bottleneck (8), comprising: a pump body (2) made of a flexible material, a suction mechanism enclosed in the pump body (2) made of a flexible material And a rigid sleeve (4) inserted between the suction mechanism and the pump body, the top of the pump body (2) is fixed to the neck (8) after the pump is assembled in the neck (8) On the outer edge (12), the rigid sleeve (4) is equipped with a ring (6) embedded in the pump body (2), characterized in that the ring (6) can be located on the ring An annular space (10) is provided between the outer surface (4a) of the sleeve (4) above (6) and the opposite inner surface (2a) of the pump body (2), the dimensions of said annular space (10) Customized so that, after assembly, the radial distance between the outer surface (4a) of the sleeve (4) and the opposing inner surface (8a) of the neck (8) is greater than or equal to that of the sleeve (4) in the uncompressed state. The thickness of the pump body (2) made of a flexible material. International Application 2003-11-24 PCT/EP2003/013185 International Publication 2004-06-10 WO2004/047999
