Description
Vynález se týká způsobu výroby celopolyethylenové funkční vestavby laboratorní střičky.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for the production of a full polyethylene functional assembly of a laboratory syringe.
Funkční vestavba laboratorní střičky se dosud vyrábí tak, že se vytvaruje ohnutá skleněná tryska s kónickým rozšířením a ta se nasadí na polyethylenovou trubičku. Vedle poměrné pracnosti při zhotovování vestavby je značnou nevýhodou skutečnost, že při manipulaci se střiČkou dochází často k porušení skleněné části vestavby a tím i k možnosti vzniku úrazu.So far, the functional assembly of the laboratory spout has been made by forming a bent glass nozzle with a conical extension, which is placed on a polyethylene tube. In addition to the relative effort in the construction of the installation, the disadvantage is the fact that the glass part of the installation is often damaged during handling of the spray and thus the possibility of injury.
Uvedené nevýhody odstraňuje způsob výroby funkční vestavby laboratorní střičky podle tohoto vynálezu, který spočívá v tom, že se jeden konec polyethylenové trubičky o vnějším průměru 6 až 10 mm a tlouštce stěny 0,8 až 2,5 mm za tepla vytáhne do trysky o průměru 0,5 až 2,5 mm, ve vzdálenosti 60 až 100 mm od trysky se trubička opatří kónusem o průměru rovnému 1,1 až 1,8 násobku vnějšího průměru trubičky, přičemž trubička se v místě mezi tryskou a kónusem ohne o úhel 100 až 140°.The above drawbacks are avoided by a method of manufacturing a functional assembly of a laboratory spout according to the present invention, wherein one end of a polyethylene tube having an outer diameter of 6 to 10 mm and a wall thickness of 0.8 to 2.5 mm is pulled into a nozzle having a diameter of 0 , 5 to 2.5 mm, at a distance of 60 to 100 mm from the nozzle, the tube is provided with a cone with a diameter of 1.1 to 1.8 times the outer diameter of the tube, the tube bending at an angle of 100 to 140 at a point between the nozzle and cone °.
Zejména při kusové výrobě funkčních vestaveb je výhodné, jestliže se po vytvoření trysky jejíParticularly in the case of the piece-making of functional assemblies, it is advantageous if its nozzle is formed
