Definitions

  • the invention relates to a lid for producing a container having at least one bung with a preferably cylindrical body, the lower end of which is connected tightly and firmly to a bottom and the upper end of which is connected to a lid, the lid being provided for connection to the body Has edge, which is followed by a short jacket area provided for engagement in the fuselage and enclosing its top surface, and in which the top surface is provided with at least one filling opening, the edge of which can be connected to a connecting piece of a closure (bung).
  • lids with cover surfaces which have just been constructed are usually used;
  • the disadvantage here is that such just executed lids easily deform and are deformed owing to relatively small, external forces remaining ugly.
  • containers of smaller size for example cans or containers for small amounts of lacquer or paint, but also foodstuffs, circular beads of shallow depth are embossed into the bases of the floors and the lid in order to stabilize these bases.
  • lids with slightly convex cambered top surfaces are preferably used, which have an advantageously increased section modulus against deformation.
  • bungs are not at right angles on the surface area which supports them, but that in the case of bung drums equipped with cambered lids, the two bungs which are usually provided on opposite sides are inclined and show diverging axes. Furthermore, it has been shown with sheet drums that their complete emptying is problematic: when emptying via suction pipes of pumps, they will generally not be able to take up a last pool in the bottom areas, and when trying to empty them completely by pouring out, significant quantities can also be found, for example do not remove from a liquid.
  • the invention is based on the task of creating a lid of a type corresponding to a container, in particular a barrel, which, if necessary, can be emptied practically completely by placing it on its lid or its edge areas, and which can be placed on the filling openings Filling nozzles can be economically connected to the lid so that they do not protrude or only slightly protrude beyond the edges of the filling opening into the interior of the container.
  • a cover 1 is shown in vertical section and in plan view, which is provided for the manufacture of a bung. From an edge 2 used to establish the connection by in particular folding and / or welding with the body of the sheet pile, a jacket region 3 of low height extends downwards, which is provided for engaging in the body of the sheet pile to be formed and both the seat of the cover secure as well as stabilize the upper edge of the shell of the fuselage.
  • the jacket area 3 is followed by a cambered top surface 12 for reasons of stability and dimensional stability, into which filling openings 6 and 8 are incorporated, for example punched out, for receiving sockets or flanges of the container closures or bungs, of which the filling opening 6 is filled with a Larger diameter of, for example, 2 "and the filling opening 8 with a smaller diameter of, for example, 3/4".
  • the filling openings 6 and 8 surrounding surface areas 5 and 7 are pressed out from the convex top surface 12 of the lid 1 in a normal manner.
  • transition regions 17 which are essentially frustoconical, although, as can be seen in particular in FIG. 1, the surface line adjacent to 17 and thus pointing outwards is longer than the surface line directed inwards and designated by 18.
  • the basic form itself can be changed significantly. It is thus possible to design the indentations leading to the surface areas 5 and 7 deeper or to press these surface areas 5 and 7 more firmly.
  • the surface areas having the filling openings do not necessarily have to be annular, they can also have the shape of regular polygons or ellipses, without their configuration being restricted to strictly detectable geometric shapes. It is also possible to design the transition region 17, for example, in the shape of a truncated pyramid.
  • the additional deformation to obtain the normal surface areas 5 and 7 further stabilizes the top surface 12 of the lid 1 or is equipped with a higher resistance to deformation, which results both from the reinforcing shape itself and also due to the material hardening achieved during cold forming.
  • the axially normal surface areas 5 and 7 result in axially parallel arrangements of the nozzles after the welding of the nozzles into the filling openings, and the conical elevations shown in FIG. 1 result in funnel-shaped depressions which promote emptying after a barrel has been moved onto its lid , so that even with conventional flanges, pipe lugs and the like protruding into the interior of the container, the funnel effect results in more extensive emptying than previously possible.
  • a further cover 1 is shown in vertical section with a flat, the later connection serving edge 2, which is followed by a jacket area 3.
  • a ring zone 4 preferably along the circumference and the same width, which ring zone may run within a plane normal to the axis axis, but preferably towards the vertical axis of the cover, not shown, that is to say in a radial direction Direction increases slightly, for example by 0.5 ° to 5 °, so that when the barrel having such a lid is rotated by 180 ° for the purpose of emptying, this ring zone has an inward slope towards the top surface 10.
  • the ring zone 4 is adjoined by a surface area 5 which is arranged essentially horizontally and which surrounds a filling opening 6, into which the nozzle of a bung closure is welded during further processing of the cover 1.
  • the surface area 5 is thus at the same level as the inner boundary 15 of this ring zone, which terminates the ring zone 4 and which is indicated by a short dash as well as the opposite end of the surface area 5 and further zone ends.
  • the essential cover surface 10, which closes the base surface of the cover 1 extends with a slope directed towards the inner boundary of the opposite regions of the ring zone 4, which is at least 0.2 °, better 0.5 ° to 5 °. Since the end of the top surface 10 facing the opposite edge region of the ring zone 4 is at a lower level than the inner boundary 15 of the ring zone, this level rises again via a transition zone 9 to this inner boundary.
  • another horizontal surface area 6 is embossed, which has a filling opening 8, the diameter of which is smaller than that of the filling opening 6.
  • a Welded socket so that it then shows the usual bung with 2 "and 3/3" diameter.
  • transition zone 9 As the top view of FIG. 5 shows, enclose the top surface 10 approximately moon-shaped and show the maximum of their width in the deeper areas shown on the right in the drawing and decrease their width toward both legs.
  • the top surface has a slightly convex design.
  • care must be taken here that each section of the cambered top surface 11, which has different inclinations, runs with a slope. According to FIG. 3, this was achieved in that the cover surface 10 was guided essentially along a degree 16 intersecting the centers of the filling openings 6 and 8.
  • this begins in the areas of this top surface adjoining the surface region 5 with an inclination, even if only slight, which is correspondingly increased to the right in the drawing by the cambering.
  • the second, smaller filling opening which is in the normal Position the barrel at a lower level and in the opposite position at a higher level: here the air filling the container can easily penetrate without being disturbed by the remaining contents or allowing it to escape a second time.
  • the residual emptying is optimally promoted, but on the other hand it is also largely facilitated.
  • the effort required for this is only moderate, since the cover surface has to be pressed out of the blank anyway and the additional shaping can be carried out without any significant additional effort or labor, and at the same time also requires an advantageous increase in the section modulus of the cover.
  • FIGS. 6 and 7 are provided with the already known reference numbers, so that a basic description is unnecessary. It is found to be essential, however, that a bead 14 adjoining the inner boundary of the ring zone 4 is additionally embossed. This bead begins on the right side of the drawing at approximately the level of the inner boundary 15 of the ring zone 4 and then rises with its apex so that it opens wide into this surface area at the level of the area 5 of the filling opening 6.
  • the ring zone 4 drops in the direction of the subsequent bead 14, which after its reversal proves to be a gutter.
  • This trough surrounds the entire inner boundary 15 of the ring zone 4 with a slope towards the opposite ring surface 5 and opens into it and is thus able to supply the entire liquid collected to the filling opening 6.
  • the top surface 13 itself can be flat, and it can be either convex or concave. There is also the possibility, in the region of the straight line 16, of guiding the top surface along a straight line connecting the facing ends of the surface regions 5 and 7, the top surface 13 being able to be designed as a gradient-containing plane or as cylindrical or can be arched elliptically so that this line appears as a generatrix. Furthermore, it is also possible to put together any curvatures, for example by introducing a first cylindrical curvature when the surface of the cover surface is formed, the axis of which extends parallel to the straight line 16 and which is overlaid by a second curvature, the axis of which lies within the plane of the drawing the straight line 16 runs parallel to other vertical lines.
