THE APPLICATION OF MICRODOTS AS IDENTIFIER LABELS

摘要

Microdots as identifier labels are applied to an article drawing a mixture of microdots and adhesive from a container (2) using pressurised air. A discharge part (4) is coupled to the container (2) and has a passage (6) with an inlet portion and a discharge outlet (8). A nozzle (10) separately formed from the discharge part (4) is fitted into the passage (6) in the discharge part (4); the nozzle (10) is fitted onto an outlet component (14) of a system for supplying air under pressure. Air fed under pressure via the nozzle (10) and into the passage (6) draws the mixture from the container body into the passage (6) for discharge through the discharge part (4) for application to the article. After use the nozzle (10) is removed from the outlet component (14) of the air supply system and the container (2), the discharge part (4), and the nozzle (10) are then discarded. Accordingly the outlet component (14) of the air supply system remains free from any contamination with the microdot/adhesive mixture and can thereby be used for a subsequent application without the need to clean it.
