<p>An adapter connecting between a rigid container with one drain opening and a liquid demanding device, comprises one attachment port for sealing connection to the container's drain opening and a valve connecting to the flow-passage between the attachment port and connection means for the liquid demanding device, for equalizing pressure inside the container. Characterizing means are: attachment means (2) to keep a container sealingly attached in the drain opening; connection means (7) having externally a prismatic or cylindrical form (10) fitting in a corresponding deep hole in the device, wherein a sealing to the prism or cylinder's surface between the interior of the deep hole and the surroundings is established; and a take-out valve (11) in the flow direction in the connection port (8), being opened by means in the device (9) after sealing to the prism or cylinder (10) has been established. Easy connection to various containers and no spillage when not in use are the main benefits.</p> |
