1. , for a method for batch micro operations multi-part themoplasticity closing piece, this themoplasticity closing piece is used for the fluid product in airtight container, and this container has entrance, and this enters the neck of interruption-forming container, said method comprising the steps of:

  • A. material segment that is continuous, elongated, substantially cylindrical shape is extruded, for the formation of the core components of closing piece;

    B. make the material segment of described continuous, elongated, the substantially cylindrical shape of the core components forming closing piece by printer system, for repeatedly by the surface of label print needed for predetermined at the material segment of described continuous, elongated, substantially cylindrical shape;

    C. extrude separately one deck to be separated and the plastic coat of independently visually-clear, this plastic coat closely adhesively engages with the material segment that is described continuous, elongated, substantially cylindrical shape forming core components, this separation and independently plastic coat periphery around with the basic cylindrical surface surrounding the material segment of described continuous, elongated, substantially cylindrical shape, and be printed on described continuous, elongated, substantially cylindrical shape material segment surface on be marked as overlapping relationship, and form two parts product;

    AndD. in the plane substantially vertical with the central axis of material segment of elongated, continuous, the substantially cylindrical shape forming core components, this pair of parts product is cut, thus form the multi-part themoplasticity closing piece with Len req, for inserting and remain in the entrance of the neck of container;

    Wherein;

    described method also comprises, make the material segment of described elongated, continuous, substantially cylindrical shape by printer system before pretreatment is carried out to increase cementability and/or the moisturing capacity of core components to the outside face of material segment of described elongated, continuous, the substantially cylindrical shape forming core components.
