Definitions

  • the invention relates to a container with at least one thin-walled pipe socket which is assigned to a filling opening and is provided with an internal thread for receiving a sealing plug.
  • an internal thread can also be formed by a correspondingly supported, helical spring made of steel wire, but here, too, expensive welding work or extensive deformation work is required in order to space the helical spring at intervals or over its entire length against axial stresses to accommodate securely.
  • beer barrels made of aluminum are known, in the filling openings of which bung are welded.
  • the bung In order to enable problem-free welding, the bung must also be made of light metal, which, however, turns out to be too soft to enable repeated closing by means of sealing plugs or connecting lines.
  • a first thread is therefore incorporated into the thick-walled bung, into which a threaded bush made of harder material, preferably steel, can be screwed, which in turn has a second thread, a resilient internal thread for receiving sealing plugs or the like.
  • the internal thread of the sheet pile can be produced relatively easily, thick walls and thus a high use of material are just as necessary as complex, tight and absolutely tight welding.
  • the invention is therefore based on the object of connecting a thin-walled pipe socket, which is formed in one piece from the lid of a container and surrounds its filling opening, with an internally threaded threaded bushing in such a way that a firm, heavy-duty hold is obtained even without complex welding work and, if possible, also the reuse of favorable exchange of such a threaded bushing is made possible.
  • the threaded bushing is in this case received by the pipe socket with a press fit or by form-fitting elements which can withstand the torques which occur when a sealing plug is screwed in.
  • form-fitting elements are optionally provided. This allows the threaded bushing to be pressed into the pipe socket, hooked in or screwed in and thereby achieving a firm hold, but can usually be easily removed again if necessary and replaced by another threaded bushing.
  • a broken top floor 1 is shown in half section, from which in the formation of a filling opening a pipe socket 2 was formed upwards, the free end of which is rolled into an almost closed bead 3, the free upper end of which is approximately flat offers annular sealing surface 4.
  • a threaded bushing 6 equipped with an internal thread 5 is inserted into the pipe socket 2, the upper end face 7 of which lies against the bead 3, and the lower end of which is equipped with a flange 8 which engages under the root of the pipe socket 2.
  • a sealing plug 9 with its external thread 10 is screwed into the internal thread 5 of the threaded bushing 6.
  • the top plate 11 of the sealing plug lies over the seal 12 and presses it sealingly against the sealing surface 4 of the bead 3.
  • the manufacturing tolerances of the threaded sleeve 6 and the pipe socket 2 can be kept wide if the inner jacket of the pipe socket 2 and / or the outer jacket of the threaded sleeve 6 are roughened, for example knurled or otherwise provided with a texture, and it is also possible for the to achieve a firm fit after insertion using an adhesive, for example an industrial adhesive, which is placed on the outer jacket of the threaded bushing and / or the inner jacket of the pipe socket.
  • FIG. 2 A simplified, varied exemplary embodiment is shown in FIG. 2, in which essentially the reference numbers already used are adopted.
  • the bead 3 runs out into an inwardly projecting flange 13 which is able to securely support the upper end face 7 of the threaded bush 6 and at the same time offers a wide sealing surface 4 of the seal to be applied; when tightening the sealing plug to be introduced, not shown, the Collar 13 and the seal to be applied clamped directly between the top plate of the sealing plug and the threaded bushing 6.
  • FIG. 3 A similar arrangement with a wide sealing surface 4 results from FIG. 3, in which the bead 3 ends in a collar 14 directed downwards.
  • Fig. 4 shows an arrangement corresponding to FIG. 2, in which the threaded bushing 6 is equipped with a centering tubular extension 15 which passes through the removal opening formed in the bead 3, and in the lower region of the threaded bushing 6 there is a conical extension which promotes the outflow 16 arranged.
  • FIG. 5 again shows an arrangement largely corresponding to FIG. 2, in which the threaded bushing 6 is equipped with at least one groove in which a sealing O-ring 17 is held.
  • This O-ring 17 additionally seals the gap formed between the pipe socket 2 and the outer jacket of the threaded bushing 6, and at the same time it can exert a certain clamping effect when pressed in, which remains approximately constant even with wide tolerances of the metal parts.
  • the support against the axial forces occurring when tightening a sealing plug is in turn provided by a flange 13 which overlaps the upper end face 7 of the threaded bushing 6.
  • an essentially conical pipe socket 18 is formed in the top floor 1, the free end of which is rolled into a bead 3 and supports the threaded bushing 6 with a collar 14.
  • This is also conical, and an internal thread 19 is pressed into the conical pipe socket 18, into which the corresponding threads of an external thread 20 of the threaded bushing 6 engage.
  • This thread can be designed as a relatively coarse round thread, and it can optionally be designed with multiple threads.
  • the threaded bushing 6 can also be provided with troughs or grooves that move around it, into which knobs embossed into the threaded connector 18 engage. In any case, a certain hold is achieved here on the one hand, and the axial forces occurring when the sealing plug is tightened are intercepted by the collar 10 and the conical surfaces lying one on top of the other.
  • the collar 14 of FIG. 3 is pulled down so far that an inner jacket 21 lining the pipe socket 2 results.
  • the threaded bushing 6 is at least supported against rotation and slipping out by a press fit, adhesive bonding or interlocking elements, and the strong axial forces that occur when the sealing plug is tightened can be absorbed by the front groove 22, a shoulder 23 and a flange 24.
  • this flange is like this cantilevered and equipped with its end facing the top floor flange 25 that its free end acts as a sealing lip 26.
  • the shoulder 27 is arranged below the free end of the inner jacket 21, so that it cannot take on any supporting forces.
  • an inner jacket 21 of a pipe socket 2 is provided, and the threaded bushing 6 engages with an external thread 29 in helical beads 28, which are pressed into the inner jacket 21.
  • knobs, troughs or grooves can be provided instead of the threads, and the thread can be designed as a so-called plug-in thread instead of with continuous screw threads.
  • it can prove to be expedient not to impress beads or to push them outwards into the inner jacket, and there is also the possibility of punching the projections or recesses receiving threads into the inner jacket, expediently before the latter is pressed through.
  • the anti-rotation device can also, as will be explained with reference to FIGS. 10 and 11, be achieved in a form-fitting manner by deviating from the rotational shape.
  • a recess 30 for receiving a flange 31 of the threaded bushing 6 is provided in the root region of the pipe socket 2 of the top floor 1.
  • the flange 31 is not ring-shaped, but regularly designed octagonally, and a corresponding base also has the recess 30, so that on the one hand a hold against axial forces is offered and on the other hand any torque can be absorbed .
  • the threaded bushing is not only easy to insert, but also easy to replace if necessary.
  • the inner jacket 21 of the pipe socket 2 ends here in a conically tapering region 32, and the threaded bushing 6 has a correspondingly designed conical extension 33.
  • It is also equipped with a plurality of outwardly projecting locking lugs 34 which engage in an internal thread stamped or machined into the inner jacket 21, which expediently begins as a plug-in thread with vertical slots beginning in the region of the bulge 3 and in the height of the locking lugs approximately angled guide groove having.
  • These are expediently guided with a slight slope so that when the threaded bushing 6 is rotated axially, it is clamped against the end region 32 with its conical extension. If necessary, a slight undercut can be provided in the work area, which makes loosening difficult or prevents automatic loosening.
  • a bead 3 of a pipe socket 2 is used as a sealing support, which is formed in one piece from the top 1 of the container, so that a secure seal is obtained.
  • the manufacturing costs are simplified, since the pipe socket 2 is created without special material and by simple shaping processes, while on the other hand the threaded bushing, as a simple turned part, allows cheap manufacture.
  • the assembly can be carried out by simply pressing it in, if necessary twisting it, and if desired an industrial adhesive can be added. The invention thus simplifies the manufacture of containers, in particular sheet drums, the sealing of the container contents remaining secured or even improved.
