Definitions

  • the invention relates to plastic drums which are designed as bung drums or lidded drums and manufactured as single or multi-layer containers by extrusion blow molding.
  • Bung barrels of this kind from the GB-A-2 219 270 are known, have a barrel body with an upper bottom, a lower bottom and an upper and a lower edge with an L-shaped cross-section.
  • the upper drum base has two troughs, in each of which a threaded socket is embedded with an opening.
  • the two troughs in the upper floor and the lower floor are provided with an outer metal coating
  • the barrel body has an outer strip-shaped, metallic coating
  • the lower barrel bottom has an outer metal coating
  • via the electrically conductive strips on the outer wall of the drum body is electrically connected to the electrically conductive coating of the two wells in the upper drum base and thus the surface of the bung barrel is electrically grounded.
  • the invention has for its object to further develop the generic plastic barrel for liquid and granular products in terms of a secure and comprehensive electrical grounding.
  • the electrical grounding of the barrel surface and the interior of the plastic cup as well as the transported in this or to be stored liquids allows the use of the barrel as dangerous goods for flammable liquids and Emulsions as well as solvents, paints and varnishes with a flash point ⁇ 35 ° C as well as the use of the drum in operating rooms, in which an explosive atmosphere can be formed by gases, vapors or mist.
  • the one-piece produced by extrusion blow bung 1 plastic especially high density polyethylene, consists of a barrel body 2 with a cylindrical barrel shell 3, a bottom 4, a topsoil 5 with a filling and emptying 6 and a ventilation bung 7, the sunk arranged in the topsoil 5 and the openings 6a, 7a are closed by bung plug formed as a bung plug, and with an upper, designed for the attachment of a barrel gripper support ring 8, which has an L-shaped cross-sectional profile.
  • Fig. 2 shows that barrel 3, bottom 4 and topsoil 5 of the bung barrel 1 of an inner layer 9, a middle layer 10 and a permanent antistatic outer layer 11 with a Leitrußanteil consist of a specific Surface resistance ⁇ 10 5 ohms and a volume resistivity ⁇ 10 3 ohms guaranteed.
  • the thickness of the middle layer 10 is 1 to 2, preferably 1.5 millimeters, and the thickness of the inner and outer layers 9, 10 is 0.1-0.5 millimeters, preferably 0.2 millimeters.
  • a recycled granulate or regrind of pure polyethylene and / or polyethylene is used with a Leitrußanteil, and as starting material for the inner and the outer layer 9, 11 is a virgin polyethylene granules.
  • Fig. 3 shows a six-layer construction of the bung barrel 1 with an inner layer 9 of pure high-density polyethylene (HDPE), a barrier layer 12 of polyamide (PA) or an ethylene-vinyl acetate copolymer (EVA) against the permeation of oxygen and hydrocarbons in two adhesive layers 13th 14 is embedded in a low-density polyethylene (LLDPE), a middle layer 10 of recycled granules or regrind of pure high-density polyethylene and / or high-density polyethylene having a conductive carbon black portion and a high-density polyethylene end-tautant outer layer 11 having a conductive black portion.
  • HDPE high-density polyethylene
  • PA polyamide
  • EVA ethylene-vinyl acetate copolymer
  • the barrel body 2 of the bung barrel 1 are formed as strips 16, electrically conductive portions 15 of a high-density polyethylene integrated with a Leitrußanteil that form electrical connections between the inner surface 17 and the surface 18 of the bung barrel 1 and the thickness of the wall thickness 19 of the bung barrel equivalent.
  • the bung barrel 1 is electrically grounded via the electrically conductive strips 16 and the permanent antistatic outer layer 11, so that electrical charges that occur on the inner surface of the barrel and in the liquid product and on the barrel surface are discharged into the ground.
  • the drum lid made of plastic, in particular high-density polyethylene with Leitrußanteil injection-molded.
