Gerresheimer Develops Twist-Off Closure

As the cap is closed the seal presses against the rim of the filled container and with the cap closed it is finally fixed in place by means of induction.

2/22/2011 --- Tablet manufacturers supplying both European and US markets no longer need to adjust their filling processes to take account of different packaging systems: under the Duma brand name, Gerresheimer has developed a twist-off closure which also includes the foil seal required for the container in the USA. Whether with an integrated seal or without: externally the containers are completely identical.

In the past, fillers had at least to use different closure types for their tablets if they wished to supply Europeans and Americans in parallel: to date, no universal solution has existed - although there was certainly demand for one: ”With this new development we fulfill a widespread customer wish,? says Burkhard Lingenberg, Director of Marketing and Communication for the Gerresheimer Group. ”For international pharma markets there should as far as possible be uniform packaging it's simply a question of efficiency.

The optional US seal is hidden away inside the twist-off cap. As the cap is closed the seal presses against the rim of the filled container and with the cap closed it is finally fixed in place by means of induction. When the cap is opened again the foil divides into two layers: its aluminum layer stays firmly in place on the container as a seal the auxiliary layer of plastic remains in the closure.

It fits all 38-mm containers in the Duma Twist-Off and Duma Twist-Off Q product lines and naturally meets all the relevant pharmaceutical requirements. Top quality is guaranteed by the international competence center of Gerresheimer Plastic Packaging in Vaerloese (Denmark): the innovative concept was also developed here.
