摘要:
604073 A needle shield (1.1) comprising at least two different plastic materials of different flexibility and a central aperture (1.1.3) of variable diameter. The central aperture comprises a first diameter (D1) for retaining a needle cap (2.2) therein. The diameter of the central aperture changes upon removal of the needle cap from the first diameter to a second diameter (D2) by virtue of a memory effect of the material of the needle shield. At least one of the plastic materials has a shape memory. The needle shield is made by a two-shot injection moulding process.
