Child-resistant Duma cap from Gerresheimer


Gerresheimer presented its Duma Standard child-resistant container with a child-resistant handy cap at Pharmapack in Paris, in February

Children experiment with everything, including medicines. This means tablets must be stored out of the reach of children but sometimes it is all too easy for children to find them.

Packaging like the new Duma Standard child-resistant (CR) container with its CR cap is designed to prevent young children from getting hold of items like medicines that could be harmful to their health.

This is the company’s first snap-on cap with CR solution. The snap-on cap is a one-component-system compared to more conventional child-resistant screw-cap solutions that are made of two components.

Many products that could pose a threat to young children’s health are required to incorporate a safety device under national and international law. ISO standard 8317 (2015) applies in Europe and US 16 CFR section 1700.20 in the US.

ISO 8317 (2015) is the international standard for re-closable CR packaging. It governs both pharmaceutical and technical chemical products.

The standard describes two test procedures, which any packaging to be tested must be subject to. One test is run with a group of up to 200 young children aged between 42–51 months.

They must not be able to open the packaging, which is filled with a harmless replacement substance. At the same time, a test group of older people aged between 50–70 must be able to open and re-close it without impairing the child-resistant function.

Packaging will only meet the requirements of ISO 8317 (2015) if the tests demonstrate they are safe for children and user-friendly for the elderly, as defined in the standard.

During the test, children have an initial five minutes to try opening the packaging. Afterwards, they are shown how to open it once without any explanation. They then have another five minutes to try opening it.

The packaging is deemed child-resistant if no more than 15% of children are able to open it within the first five minutes. A maximum of 20% of children are permitted to succeed in getting at the contents of the packaging for the entire duration of the test.

If only a few young children manage to open the packaging, the test group could be reduced to fewer than 200 children as part of the sequential evaluation process.

During the test, the participants have an initial five minutes to try opening the packaging. They are not shown how to do so besides the instruction on the packaging. In the second phase, they only have one minute to try and open it. The packaging is deemed suitable for older people as long as at least 90% of the test group are able to open and re-close it again without impairing the CR function within a reasonable amount of time.

The test group is designed to include 100 people, of whom 25 are aged between 50–54, 25 are between 55–59, and 50 between 60–70.

The US 16 CFR section 1700.20 regulation also stipulates the requirements child-resistant packaging must meet. These are similar to the standards applicable in Europe but are even more extensive for medicines.
