Trigger sprayers are asymmetric and prone to tangling.
Trigger sprayers are among the more difficult closures to feed because the head, trigger lever and tube can all catch or point in the wrong direction. Bulk behaviour must be checked before choosing a feeder style.
A feeder route may include bowl tooling, guides, sensors, a controlled track and a placement handover matched to the capping station. The bottle format matters because trigger orientation can affect presentation on the finished pack.
For contract packing or multi-product lines, changeover requirements should be discussed early to avoid excessive setup time.
