Definitions

  • the invention relates to a plastic ace that can be closed with a cover and a clamping ring, corresponding to the features in the preamble of patent claim 1.
  • the clamping ring is designed as a clamping band (DE-PS 28 27 848).
  • the object of the invention is therefore to find a closure for a plastic barrel of the type specified, which maintains the required tightness between barrel and lid even under high loads, in particular those with permanent deformation on the barrel neck and / or lid.
  • the invention provides the design of the clamping ring specified in the characterizing part of patent claim 1. Further features of the invention are specified in claims 2 to 4.
  • the tension wire according to the invention can be used to better absorb and dampen the shock loads that occur than is the case with a tensioning ring designed as a tensioning band or as a spring steel wire as a closure member.
  • a tensioning ring designed as a tensioning band or as a spring steel wire as a closure member.
  • the “soft” tension wire according to the invention enables this deformation to be carried out even if a permanent deformation of the barrel neck and / or lid has occurred, and thus an always positive connection between the barrel and lid.
  • the remaining tensioning force is sufficient to pull the lid and its seal against the opening edge of the barrel neck to such an extent that the tightness between the barrel and lid remains intact even in these extreme cases.
  • loads that lead to permanent deformation of the barrel neck and / or lid since in these cases the hard impact or impact, in particular the rebound of the liquid in the barrel against the lid, due to a limited plastic deformation of the Tension wire is softly cushioned, but is then intercepted elastically.
  • 1 denotes the barrel neck located at the upper end of a barrel body and forming the barrel opening, while the lid for closing the barrel opening is designated by 2.
  • the barrel body with the neck 1 is preferably blown in one piece from plastic, and the cover 2 is also preferably made of plastic.
  • the barrel body and barrel cover expediently have the same physical and mechanical properties.
  • the barrel cover 2 engages with a ring web 3 projecting vertically from the underside into the barrel opening and engages with the outer edge 4 of the barrel opening so that an annular groove 5 receiving the barrel neck 1 is formed, inside which there is an inserted elastic sealing ring 6, which When the cover 2 is placed on the barrel neck 1, it lies on the opening edge 7 thereof or an annular fold 8 formed thereon and projecting upwards.
  • segment-like arranged on the circumference arranged lugs 9 are provided, which can be shaped as a hollow body from the neck wall by the blow molding process.
  • the outer edge 4 of the cover 2 has cover segments 10 which protrude downwards into the spaces between the lugs 9 of the neck 1 with foot parts 11 which are angled radially outwards.
  • the lugs 9 and the cover segments 10, 11 thus form a type of circumferential toothing which is dimensioned such that when only loosely fitted Cover between the lower surfaces 9 'of the lugs 9 and the surfaces 11' of the foot parts 11, an annular gap 12 is formed, into which a clamping ring in the form of a tension wire 13 can be drawn (Fig. 1).
  • the surfaces 11 'of the foot parts 11 have a slightly rising in the radial direction
  • the lower surfaces 9' of the lugs 9 have a slightly falling profile, so that when the tensioning wire 13 is tightened and tightened by means of a turnbuckle, the tensioning wire expands the annular gap 12 radially inwards is pulled, whereby the cover with its cover segments 10, 11 is pulled down between the noses 9 serving as abutments for the tensioning wire 13 and is firmly clamped with the barrel neck 1 while compressing the ring seal 6 (FIG. 2).
  • the barrel body merges with a tapered area 14 into the barrel neck 1 without a constricted shoulder, only in the area of the cover segments 10, 11 being expressed from the tapered area 14 of the barrel wall in a columnar manner extending supports 15 are provided, as explained in detail in DE-PS 28 27 848.
  • the tension wire 13 used is made of soft material that deforms from a certain tension on plastic or permanent.
  • the thickness or size of the cross-sectional area and the physical and mechanical properties of the material of the tension wire are selected so that the stress or tension causing the permanent or plastic deformation of the tension wire is in any case below the limit value for permanent deformation of the plastic barrel and / or lid is, the tensioning wire is already plastically deformed and absorbs impact energy before permanent deformations occur on the material of the plastic barrel and / or cover.
  • the tensioning wire must of course have sufficient elasticity to maintain a permanent closing tension between the barrel and the lid, which is sufficient below the predetermined limit stresses still resilient.
  • a tension wire made of mild steel with a tensile strength of approximately 70-80 kp / mm 2 and a yield point of approximately 40-50 kp / mm 2 has proven to be particularly advantageous and suitable for HD -PE blown plastic drums with a wall thickness of approx. 6mm on the barrel neck and a lid, also made of HD-PE, which is made by injection molding and has a wall thickness of approx. 4mm at the edge area.
  • Plastic aces and plastic lids have roughly the same physical and mechanical properties and load limits.
  • the tension wire has a cross section forming an abutment surface on the inner circumference, as shown in FIGS. 1 and 2 for a tension wire with a hexagonal cross section, in FIG. 4 for a tension wire with a triangular cross section, in FIG. 5 for a tension wire with an oval cross section and is illustrated in FIG. 6 for a tension wire with a square cross-section, the content of the cross-sectional area being assumed to be about 7 mm 2 .
  • a cross-sectional configuration forming an abutment surface on the inner circumference of the tension wire is considered to be advantageous in that a force transmission which is better adapted to the relatively soft material of the tension wire can thereby be brought about.
  • the tension wire can also have a round cross-section, as is illustrated in FIG. 3 for a tension wire with a cross-sectional area which is also approximately 7 mm 1 .
