If a beverage starts to ferment and increased internal pressure builds up in the bottle, this can be unpleasant or even dangerous when it is opened again. A new 38-millimetre cap from Bericap for milk and juice drinks solves this problem with innovative venting technology.<\/strong><\/p>

Who hasn't experienced this? It happens in a bottle of fruit milk or juice when it is resealed after the first consumption and then stored without refrigeration and under the influence of light: The drink starts to ferment and pressure builds up in the bottle, which can be dangerous if you open the bottle again. During this unintentional fermentation, up to five bar of internal pressure can build up in closures without venting.<\/strong> If the bottle is then opened, the drink foams up, the lid shoots up and potentially injures the consumer. That would be fatal, also for the brand's image. Cap manufacturer Bericap<\/a> has now developed a solution to this problem.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The manufacturer's new 3438 closure features the patented \u201eSafe Venting\u201c technology, which reduces the pressure inside the bottle to a safe level of one to two bar. At the same time, a double seal prevents liquid from entering or escaping. This makes the closure very safe for practical use. When a critical value of around two bar is reached, the pressure created by the uncontrolled fermentation in the bottle is released through a venting slot.<\/strong> This groove in the closure therefore takes on the function of a safety valve: it closes again immediately after depressurisation.<\/p>

Tests carried out by the company on this new development in comparison with conventional 38-millimetre closures delivered the following results: a reduction in the internal pressure in 0.5-litre bottles from 3.6 to 2.0 bar and in 1.5-litre bottles from 4.0 to 1.6 bar. Uncontrolled foaming is prevented.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The new 3438 is also available in Germany as a standard safety cap or as a tethered cap under the name \u201eClipAside\u201c. This means that customers already have the option of selecting a customised closure solution for each product.<\/strong> The ClipAside closures meet the requirements of the Single Use Plastics (SUP) Directive from 2019, which stipulates that closures on single-use beverage containers with a volume of up to three litres must remain attached to the bottle after opening until disposal. The aim is to reduce plastic waste.<\/strong> Therefore, all affected beverage manufacturers must have converted their products to tethered caps by July 2024 at the latest.<\/p>
