Реферат: Postupak za proizvodnju spremnika (1) s otvorom (8), koji ima vanjski spremnik (2) uglavnom krutog oblika u kojem se nalazi unutarnja vreća (3) koja dolazi u dodir sa sadržajem koji će se kasnije nalaziti u spremniku, u svakom slučaju iz različitih termoplastičnih polimernih materijala koji se međusobno ne spajaju, i otvor (10) u vanjskom spremniku (2) za izjednačenje tlaka koji postoji između vanjskog spremnika (2) i unutarnje vreće (3), pri čemu se najprije postupkom koekstruzijskog puhanja između otvorenih polovica kalupa proizvede pripravak, koji se sastoji iz dva koaksijalna crijeva, koji pripravak ima dovoljnu duljinu za izradu spremnika, zatim se kalup zatvori i uz tvorbu prema van okrenute donje linije (5) spajanja suvišak materijala izrade spremnika se odreže u području (4) dna tako da se međusobno zavare dijelovi iz materijala vanjskog spremnika (2) koji se dodiruju u područjulinije spajanja, da se crijevo koje tvori unutarnju vreću stisne između dijelova stjenke vanjskog spremnika (2), aksijalno se učvrsti i zavari, i unutarnju vreću (3) se izloži tlaku tako da stjenke pripravka prilegnu iznutra na stjenke kalupa za puhanje, naznačen time, da pri zatvaranju kalupa za puhanje i s tim povezanim oblikovanjem donje linije(5) spajanja, linija spajanja unutarnje vreće (3)se barem djelomično učvrsti aksijalno u liniji spajanja vanjskog spremnika i time se oblikuje baremjedan otvor (10) za izjednačenje tlaka, i da se neposredno nakon oblikovanja donju liniju spajanja (5) barem djelomično odreže i izloži se sili koja djeluje radijalno u smjeru linije spajanja u donjem području (4) tako da se donja linija spajanja (5) raskine, pri čemu je temperatura pripravka kod odsijecanja donje linije spajanja (5) između 40oC i70oC i vanjski spremnik (2) se još uvijek može doodređene mjere plastično deformirati, tako da deformacija uzrokovana djelovanjem sile predstavlja trajnu deformaciju i ne može se ispraviti s elastičnim povratkom. Patent sadrži još 23 patentna zahtjeva. A method of manufacturing a container (1) with an opening (8), having an outer container (2) of a substantially rigid shape in which there is an inner bag (3) which comes into contact with the contents which will later be in the container, in any case from of various thermoplastic polymeric materials which do not interconnect, and an opening (10) in the outer container (2) for equalizing the pressure existing between the outer container (2) and the inner bag (3), first by coextrusion blowing between the open halves of the mold produces a composition consisting of two coaxial hoses, which composition has a sufficient length to make a container, then the mold is closed and with the formation of the outwardly facing bottom line (5) the excess tank material is cut in the bottom area (4) so that the parts made of the material of the outer container (2) which are in contact in the area of the connecting line are welded together, so that the hose forming the inner bag is compressed between the parts of the wall of the outer joint. the inner bag (3) is subjected to axial fastening and welding, and the inner bag (3) is subjected to pressure so that the walls of the composition adhere internally to the walls of the blow mold, characterized in that when closing the blow mold and associated shaping of the bottom line (5) , the connecting line of the inner bag (3) is at least partially fixed axially in the connecting line of the outer container and thus forming at least one opening (10) for equalizing pressure, and that immediately after forming the lower connecting line (5) is at least partially cut and exposed a force acting radially in the direction of the connection line in the lower region (4) so that the lower connection line (5) breaks, the temperature of the composition when cutting the lower connection line (5) between 40oC and70oC and the outer container (2) is still it can plastically deform certain measures, so that the deformation caused by the action of force represents a permanent deformation and cannot be corrected with elastic return. The patent contains another 23 patent claims.
