Silgan Closures (silgancls.com) has launched ELC gable top caps for cartons of all formats and sizes from 28 to 35 mm. ELC eliminates the pull ring in favor of a drop-down tamper band, providing visual, audible and tactile tamper evidence.
On a standard bottle finish, the A retaining bead is a rigid ring and the flexible J-band on the closure snaps under the A bead during application. This standard design does not work on fitments due to the rigid A-bead on the finish causing damage to the tamper band bridges during application. Silgan’s patented design flips the J-band from the closure and puts it onto the finish using segmented flights. Using segmented flights creates a flexible A-bead on the finish, eliminating broken bridges.
