Germany-based Sanner has developed a new closure for effervescent tablet packaging.
The new FOG 27 lid is designed to open in about a third of the time and with 70% less physical effort compared to conventional closures.
Nearly a quarter of adults reportedly consume nutritional supplements, such as vitamins or minerals, and around half of these consumers are 60 years or older.
The German Federal Association of Senior Citizens' Organizations (BAGSO) has found that more than 90% of senior citizens struggle to open consumer packaging, and that the majority also criticise the handling properties of opening mechanisms.
Sanner product manager Ursula Hahn said: "For producers of food supplements this is a decisive factor.
"In case of bad experiences with the packaging, repurchase rates decline considerably."
Sanner noted that research institutes Quo Vadis and Packaging Intelligence have conducted a test that focused on the way of opening, as well as the time and physical effort required while using FOG 27.
The quantitative handling test surveyed 120 men and women who purchase and consume vitamin, mineral or painkiller tablets two to three times per month.
Around 87% of the participants confirmed the intuitive opening of the new closure, which requires single-handed opening.
Sanner stated that flip top of the FOG 27 is attached to the tube and can be intuitively closed.
Last March, the company launched the Brilliance tube, a packaging solution for effervescent tablets.
