Abstract (en)
[origin: EP0069246A2] A container for delivery and/or collection of a fluid, in particular a liquid. The container comprises an observation marking (9) which is adapted so as to show up in accordance with variations in the fluid level (10) in the container (1) for rapid indication of the quantity of fluid present at any given instant of observation. The observation marking (9) preferably comprises a first pattern (4) arranged on one side (3) of the container and a second pattern (6) arranged on the other side (7) of the container, the said first and second patterns being adapted so that by combined action with one another they give rise to a third clearly discernible pattern (9) in a direction of observation from the said other side (7) of the container on observation levels above the liquid level (10) in the container. The container (1) is manufactured appropriately from a flexible material, for example plastics, in the shape of a bag with at least one inlet (2) communicating with the interior of the bag. As a result of this the material properties of the bag can be utilized for a clearer showing up of the third pattern (9), since the two sides (6, 7) of the bag will be sucked towards each other owing to the vacuum which is produced in the empty space above the falling liquid level (10). A reading scale (14) adapted to the quantity of enclosed liquid may be arranged, for example, in association with the observation marking (9), so that the observation marking can be made use of also as a means for facilitating the accurate reading of this scale in that the observation marking clearly indicates the intersection between the liquid level (10) and the reading scale (14).
