The Diorshow Pump’N’Volume container features a soft TPE component to enable the brush to be optimally supplied with the creamy cosmetic product.
The Thermolast K compound gives the container the required flexibility so that squeezing the container loads the brush with mascara, said a Kraiburg TPE press release. The elastomer, it added, also provides a soft touch finish.
The bottle is made via a two-component injection moulding process. The internal structure is in copolyester and the skin is made with the TPE compound.
“We were looking for a material solution that was both flexible and aesthetic to be processed by multi-component injection moulding,” says Marion Defour-Colas, makeup packaging development group manager at Christian Dior.
“Together with Mayet, our mascara and packaging specialist, and Kraiburg TPE we have chosen a TPE compound that provides the perfect combination of properties for this application specification.”
Mayet’s project manager Sylvain Coutan added: “The decisive factor for us was that the TPE compound could ensure the compromise between copolyester adhesion, softness and low hardness while ensures the elastic recovery after repeated squeezing... during the product’s whole life cycle."
