A new range of closures reduces errors in the capping of beverages
and other food products, according to the manufacturer.

US-based Innovative Molding claims its Taperstack closure system can improve operational efficiency by reducing the error rate at which containers are capped. The company said its design also results a lighter yet structurally strong cap that resists damage during transportation and storage. "TaperStack closures increase the production efficiencies of automated capping operations by improving the consistency of proper seating on jars,"​ the company said. "This is achieved by preserving the concentric shape of the caps via the nested stack."​ Taperstack caps are designed with a stacking shelf in each closure that link together to reduce the likelihood of distortion during shipping, Innovative Molding claims. A tapered edge reduces cross-threading, reducing the chance that the cap is fitted improperly during the closure process. These features improve closure rate per case and pallet by between 40 per cent to 60 per cent over existing tumble packed closures, the company claimed. "Previous caps that were ring-nested and not TaperStacked had a tendency to stick together in twos or threes,"​ the company stated. "When going through an automated machine, they would break and you'd have plastic debris in the bottom of the hopper and broken caps going onto the bottles which needed a costly employee to separate out."​ The design also reduces the amount of material needed for the caps by 40 per cent. Weight is reduced by 20 per cent compared to similar designs, reducing freight costs, the company claimed. The caps come in 63mm, 89mm,110mm, and 120m sizes and can be adapted to containers for both liquid and dry products that require a long shelf life, the company said. TaperStack closures are available with various rib finishes and liner innerseals. Innovative Molding said it can also decorate the closures with custom embossing, debossing or printing. The company is targeting manufacturers who make liquid and dry products, including those that are hot filled and ambient filled and packed in glass and plastic containers.
