    摘要： The present invention concerns a process for the production of injection moulded glass fibre reinforced composites from extruded glass fibre reinforced pellets, said process comprising the following steps:
    (A) Providing:
    (a) Glass fibres (2) coated with a silane based sizing composition, said silane based sizing composition comprising at least one sizing reactive moiety, A1, A2, , (b)A thermoplastic matrix polycondensate (2) comprising a first matrix reactive moiety, B1, at a first end of the chain and a second matrix reactive moiety, B2, at a second end of the chain, ,
    (c) A salt (3) selected among an internal lubricant and a nucleating agent comprising a salt reactive moiety, C, capable of reacting with the at least one sizing reactive moiety, A1, A2, and/or with the first or second matrix reactive moiety, B1, B2, said salt reactive moiety, C, being selected among,
    • A metallic cation ,
    • An organic portion having a functionality, f = 1, with a reactive moiety selected among the anionic form of a carboxylic group or a hydroxyl group, and
    • An inorganic anion such as carbonate or sulphate,

    (B) Blending the glass fibres, thermoplastic matrix polycondensate, and salt;
    (C) Forming glass fibre reinforced pellets; and
    (D) Injection moulding a composite part with a composition comprising the reaction product of said glass fibres, thermoplastic matrix polycondesate and salt

    Characterized in that, the salt is added to a blend of thermoplastic matrix composite and glass fibres only after the first and/or second matrix reactive moieties, B1, B2, and the at least one sizing reactive moiety, A1, A2, are given time to react together at least partially.

    摘要： A package for smoking articles comprising an inner shell and an outer shell, the inner shell defining a space for smoking articles and the outer shell defining a cavity to receive the inner shell, the inner and outer shells being hingedly connected such that they pivot relative to each other from a closed position in which the inner shell is received in the outer shell and an open position in which the inner shell extends from the outer shell, wherein the outer shell includes a sidewall that overlaps a sidewall of the inner shell when the inner and outer shells are in their closed position, a recess being formed in the sidewall of one of the inner or outer shells and a tab extending from a corresponding sidewall of the inner or outer shell such that, when the inner and outer shells are in their closed position, the tab locates in said recess.
