Abstract

The invention concerns a method of treating rubber stoppers intended to seal packages containing sterile products. After washing, rinsing and thereafter siliconising said rubber stoppers in an emulsion of silicone oil and water, the stoppers are sterilised and dried. According to the inventive method silicone oil and water are mixed under sufficiently vigorous stirring to produce an emulsion, whereafter the resulting emulsion is transferred to a container (11) in which the stoppers are stored and the siliconising process is carried out. A device for performing this method comprises a first pump (4) arranged to pump dosed amounts of silicon, and a second pump (9) arranged to form, while exercising a strong dispersing action, an emulsion from the water and the amounts of silicon and to pump the resulting emulsion to the container (11).

(Il Uppfinningen avser även en anordning för genomför- ande av denna metod. Det som utmärker anordningen fram- går av efterföljande patentkrav 3 och 4.The invention also relates to a device for carrying out this method. What characterizes the device is stated in the following claims 3 and 4.

Uppfinningen skall i det följande närmare förklaras med hänvisning till den bifogade ritningen, som visar anordningen enligt uppfinningen schematiskt.The invention will be explained in more detail below with reference to the accompanying drawing, which shows the device according to the invention schematically.

I en ledning 1 från en tank 2 med silikonolja 3 är inkopplad en doseringspump 4. Nedströms doseringspumpen 4 är i ledningen 1 inkopplad en stängningsventil 5. Led- ningen l är ansluten till en vattenledning 6, i vilken likaledes är inkopplad en stängningsventil 7. Genom ledningen 6 matas vatten, som blandas med från ledningen l kommande, av pumpen 4 frammatade doserade mängder av silikonolja 3. Nedströms ledningens l anslutningsställe 8 till ledningen 6 är inkopplad en dispergeringspump 9, och i en ledning 10 från denna pump 9 till en behållare ll för förvaring av gummiproppar, som skall silikonbehand- las, är inkopplad ytterligare en stängningsventil 12 och en strypventil 13.A metering pump 4 is connected in a line 1 from a tank 2 with silicone oil 3. Downstream of the metering pump 4, a shut-off valve 5 is connected in line 1, line 1 is connected to a water line 6, in which a shut-off valve 7 is also connected. line 6 is fed with water, which is mixed with dosed amounts of silicone oil coming from line 1 supplied by the pump 4. Downstream of the connection point 8 of the line 1 to the line 6 a dispersing pump 9 is connected, and in a line 10 from this pump 9 to a container 11 for storage of rubber plugs, which are to be treated with silicone, a further closing valve 12 and a throttle valve 13 are connected.

Metoden enligt uppfinningen tillgår på följande sätt. Vatten och silikonolja 3 pumpas i avsedda propor- tioner in i pumpen 9. I denna sker en så kraftig disper- gering, att en emulsion bildas oavsett om silikonoljan har högre eller lägre viskositet. Emulsionen pumpas vidare in i behållaren ll, där en blandning 14 av emulsion och gummiproppar bildas. En silikonisering av gummipropparna sker nu, vilket innebär, att propparna får en tunn silikonbeläggning.The method according to the invention is available in the following manner. Water and silicone oil 3 are pumped in the intended proportions into the pump 9. In this, such a strong dispersion takes place that an emulsion is formed regardless of whether the silicone oil has a higher or lower viscosity. The emulsion is further pumped into the container 11, where a mixture 14 of emulsion and rubber plugs is formed. A siliconization of the rubber plugs now takes place, which means that the plugs have a thin silicone coating.

Enligt en vidareutveckling av metoden enligt upp- finningen blåses luft in i blandningen l4 av emulsion och så väl häftar an varvid emulsionen (silikonet) proppar, mot propparnas yta, att den återstående vätskan i huvud- sak utgör endast vatten. Detta vatten tömmes ut. På 512 231 3 tidigare känt sätt tillföres sedan ånga till behållaren för sterilisering av propparna, vilka därefter torkas.According to a further development of the method according to the invention, air is blown into the mixture 14 of emulsion and adheres so well, the emulsion (silicone) plugs, against the surface of the plugs, that the remaining liquid mainly constitutes only water. This water is drained. In a previously known manner, steam is then supplied to the container for sterilizing the plugs, which are then dried.

Behållaren ll kan sedan utgöra förvaringsställe för propparna, tills dessa skall användas.The container ll can then be a storage place for the plugs until they are to be used.

Strypventilen 13 är insatt för att möjliggöra en variabel strypning av flödet till behållaren 11.The throttle valve 13 is inserted to enable a variable throttling of the flow to the container 11.

Härigenom kan man reglera emulsionens mixningstid i dispergeringspumpen 9 i syfte att åstadkomma bästa möjliga dispergering.In this way, the mixing time of the emulsion in the dispersion pump 9 can be regulated in order to achieve the best possible dispersion.
