Sensor attachment arrangement for flexible bags

摘要

An optical sensor holding device adapted to be integrated with a flexible bag, said device comprising a bag attachment part made from a material that can be welded to the flexible bag; a sensor attachment part made from a material to which an optical sensor spot can be attached, wherein the sensor attachment part is forced into an opening in the bag attachment part that is slightly smaller than the sensor attachment part such that the sensor attachment part is kept firmly in place and leakage is minimized.

1. An optical sensor holding device adapted to be integrated with a flexible bag, said device comprising
a bag attachment part made from a same material as that of the flexible bag, and welded to the outside of a bottom surface of the flexible bag and comprising a first opening; a sensor attachment part made from a transparent material different from that of the bag attachment part and the flexible bag, to which an optical sensor spot can be attached, wherein (i) the sensor attachment part comprises at least one chamfer and is free press fit into the first opening in the bag attachment part that is slightly smaller than the sensor attachment part, and (ii) the at least one chamfer supplies a radial pressure on the sensor attachment part; and a second opening in the bag attachment part, beneath the sensor attachment part, and above the bottom surface of the flexible bag through which light passes to the sensor attachment part for optical reading.
