Finishing the Package with Closures

Closures combine two tasks: protecting the product while enabling easy access.

A sturdy, protective closure is a requirement for many pharmaceutical products. Closures must keep the product clean between uses, and in many cases they must also alert the user to tampering or prevent a child from opening the package. Closures have become increasingly varied, which means that there is a cap for every application. Users' needs are taken into consideration as well, with designs that help them use the product efficiently and easily.

A company that specializes in closures has created a tablet dispenser cap that is suitable for the pharmaceutical and nutraceutical industries. The LCC-2 tablet dispenser has an optional tamper-indicating liner. The two-piece design has a long-lasting hinge and dispenses tablets of all sizes. The design is available in two colors for the base and lid. The cap flips open to reveal the tamper-indicating liner. Other closures available include screw style, tamper indicating, and child resistant. The company also offers pharmaceutical bottles. Rexam Closures, Evansville, in.

A tamper-evident system is designed for shelf appeal. The Vistop is a two-piece, two-color system that is suitable for all types of bottles. The Vistop can be customized to fit a range of closures. The company offers a complete line of standard and unique closures and systems including dispensing, nondispensing, tamper evident, child resistant, wide mouths, and specialty dispensing systems.

A one-piece closure features flaps that cover the openings in the top of the cap. The Flapper cap has styles that allow the user to pour, sift, or spoon the product out of the container. The cap is suitable for pharmaceuticals, vitamins, and powdered supplements. The flaps close with a "snap," ensuring product containment and freshness after every use. Tamper-evident and freshness seals are available and are supplied prepunched into the Flapper closure. Sizes range from 1.3 to 4.3 in. diam. Weatherchem, Twinsburg, OH.

Rubber-free closures and components are available from a company that specializes in pharmaceutical packaging. The company's Formula 4588/40 elastomer works well for serum stoppers, IV closures, plungers, and liners for seals. Formulation 4588/40, a variation of the company's 1888, substitutes synthetic polyisoprene for dry-processed natural rubber while maintaining the functional, chemical, and biological characteristics of 1888.
