Romaco Group and Ecobliss Holding B.V. introduce Locked4Kids, a child-resistant, reclosable carton box explicitly designed for packaging pharmaceuticals. Ecobliss, the manufacturer and holder of the patent, trusts in a Romaco Promatic P 91S cartoner for the production process.
Locked4Kids cartons contain special blister trays with small hooks on the long sides. These hooks are diagonal to one another so that the tray is locked securely when it is pushed in. In order to remove the tray, both hooks have to be released simultaneously by pressing on the box firmly and evenly at the marked points with the thumb and forefinger. This is easy for adults to do but not children, whose hands are too small to span the width of the carton and push both hooks in simultaneously. Furthermore, both sides of the box are coated with a tear-resistant laminate to prevent children from ripping it apart.
The Locked4Kids concept, developed by Ecobliss Holding B.V., a Dutch supplier, is suitable as child-resistant packaging for a broad array of pharmaceutical, chemical, and toxic products in solid, powder, or liquid form. In cooperation with Romaco Promatic, Ecobliss offers a childproof packaging system based on Locked4Kids for each individual product.
Ecobliss uses a Romaco Promatic P91S intermittent-motion cartoner to package the Locked4Kids blister trays in laminated carton boxes. A wide range of applications and customer-specific feeding systems are the hallmarks of all secondary packaging solutions in the Promatic series, according to the vendor.
The asymmetrical hooks attached to the blister trays require particularly careful feeding. Owing to their unusual geometry, the trays have to be stabilized while they are being positioned in the carton boxes. The special feed tunnels used for this purpose result in highly precise processes. The Romaco Promatic P91S achieves a maximum output of 80 Locked4Kids packs/min.
The laminated carton boxes are removed and opened using Romaco Promatic’s positive carton opening system. The necessary vacuum is produced by low-noise Venturi nozzles. Promatic systems feature a consistently ergonomic design that enables format changes to be completed in less than 15 min. The complete carton magazine is retractable, for example, to allow access to all cartoner components and to speed up retooling.
