Adapter for a manually operated dispensing device of containers of liquid

摘要

The invention relates to an adapter ( 2 ) for a manually operated dispensing device ( 120 ) for a fluid that is/can be pressurized in a container. The dispensing device includes a housing ( 148 ) having a passage channel ( 30 ). A tubular adapter housing ( 34 ) connects the uptake tube ( 32 ) and the channel ( 30 ) of the housing ( 148 ) of the dispensing device ( 120 ). The adapter housing ( 34 ) has a connecting sleeve ( 42 ) for connection to the connecting nipple of the housing ( 148 ) and an uptake tube sleeve ( 44 ) for connection to the uptake tube ( 32 ). There are several inlets ( 46 ) for the fluid in the upside down position of the dispensing device. The adapter housing ( 34 ) defines at least one section of the inlets. An inlet valve ( 48 ) is defined within the adapter housing ( 34 ) for releasing the inlets substantially simultaneously when a pressure acts on the fluid in the container in the substantially upside down position of the container. A shut-off valve ( 50 ) is positioned inside a large diameter valve chamber ( 52 ) of the adapter housing ( 34 ), in such a way that the valve ( 50 ) can be freely displaced axially between two end positions.
