The exclusive plastic closure – developed and produced by Plasticum – and the glass bottle exhibit a fashionably attractive droplet shape.

To achieve this droplet shape, the a-symmetric closure and bottle should act as one and close perfectly. The Innovation & Development department of Plasticum Ede achieved a controlled swivel closing with a narrow tolerance.

The high-gloss closure is made of PP and consists of an outer part and a screw threaded inner part. The parts are assembled by a fully automated ultrasonic welding process. Special devices ensure that the closure is handled without damaging the glossy surface.

An oil based product tends to display creep behaviour and hence it presented a challenge to the Plasticum design engineers. Consequently, Plasticum concentrated on an optimised design for maximum closing.

Nivea launched two versions of the bath oil. The Golden Oil for the normal to dry skin and the Cream Oil for dry to very dry skin. In Germany – home country of Nivea – the bath oil has been marketed for some time now. The product will be available in other markets including The Netherlands, Belgium and France.
