Claims (3)

1. The process of creating a thin inner barrier layer of type I polymer inside a basic container. Containing the second type of polymer It consists of the following steps: (a) Internal heating of the mold core by feeding the heated flow into the channel along the (B) Internal heating of the mold core socket. By the flow of fluid that is heated through Numerous holes arranged in the body of the socket. And inserting the heated core into the mold core socket That is heated (c) filling the gaps formed between the axes And molded core crucibles with a type of polymer that is In the melting state, the first such polymer has predetermined blocking and / or inertia characteristics. And form a thin barrier layer directly on the heated core and whose thickness is determined by the said gap (d) the removal of the mold core and the barrier layer built up there from the mold core while The thin barrier layer remains in the melting state (e) removal of the mold core and the thin barrier layer. Into the mold cavity, the injection (f) stops the flow of the heated fluid in the mold core and guides the cooling fluid into the longitudinal cavity and cools the mold core and (g) the polymer feed. The second type, in the state of fusion, enters the inlet cavity. Of injection mold And the flow of the second polymer over the thin transverse layer, the thin transverse layer is in a melting state on its outer surface. Which is in contact with the polymer The second kind. By the above method, a basic container will be created. That consists of a thin layer on the inside of the material The barrier is built into the second polymer material. 2. The process of claim 1, plus one more step between (d) and (e), is the construction of a layer of bonding material on such a thin barrier layer. 3. The process of claim 2, where another step of the construction of the said layer. It consists of inserting a mold core with a thin barrier layer on it into another mold core, where the other mold core contains a binder.
