| 摘要 |
<p>The invention relates to a multilayer synthetic resin dose for producing multilayer objects by compression moulding comprising an axis of symmetry and consisting of a first synthetic resin (2) and at least one thin functional layer (3) of synthetic resin forming the external envelop of a body of rotation which is defined around said axis of symmetry and comprises two ends disposed in a direction parallel to the axis of symmetry. The inventive dose is characterised in that the functional layer (3) is entrapped in the first synthetic resin entirely or in such a way that not more than one end is entrapped in said first resin. ® KIPO & WIPO 2007</p> |
