Lock in Reduced Packaging Costs with One-Piece Child Resistant Closures

August 31, 2018

The Comar SecureCap® QuarterLoc™ child resistant closure helps manufacturers meet sustainability goals and reduce packaging costs without sacrificing functionality

Comar, a leading designer and manufacturer of quality healthcare packaging products, introduces the new SecureCap® QuarterLoc™ child resistant closure, a one-piece push-and-turn bottle closure that requires only a quarter turn to apply or remove. Existing two-piece child resistant closures require molding and assembly of two plastic components whereas the QuarterLoc™ closure is a single molded part.  This reduction in part weight and assembly steps translates to component part savings and a sustainability story for manufacturers of over-the-counter and nutraceutical products. Designed to be compatible with multiple products, the closure has passed the Consumer Product Safety Commission testing protocols for both child resistance and senior friendly performance.

For over-the-counter and nutraceutical product manufacturers, closure innovation has been challenged by CPSC compliance requirements for child resistant packaging and expectations to conform to industry standard capping equipment. The design of the SecureCap® QuarterLoc™ CR closure offers a cost effective solution since it is easily integrated into existing packaging lines and is both adaptable and scalable for multiple products. “Our SecureCap® QuarterLoc™ is useful for vitamin, mineral, and supplement products because of its proven child resistant performance,” says Sue Benigni, Business Segment Director at Comar. “We’re helping to deliver child-safe performance while lowering manufacturing costs,” she added. In order to offer customers a complete system, Comar has also developed bottles with neck finishes especially for use with QuarterLoc™ closures.

SecureCap® QuarterLoc™ is manufactured from polypropylene and works with PET bottles. The one-piece design reduces manufacturing complexity and is more environmentally responsible. By providing a secure closure with just a quarter turn, QuarterLoc™ is easier to use because it eliminates the potential of thread misalignment and cocked caps. Although not required, standard foil induction liners or in-line conduction liners can be used with these closures. The Comar SecureCap® QuarterLoc™ is protected by patents and manufactured in facilities that meet current Good Manufacturing Practices (cGMP) and ISO 9001:13485 quality standards.
