Definitions

  • the invention relates to a securing ring for transport securing a container formed on a preferably made of plastic, in particular a bucket, applied, preferably formed from plastic lid.
  • the invention also relates to a container, comprising: a container preferably formed of plastic, in particular a bucket, with a bottom and with a circumferential side wall, and a lid for closing an opening formed on the container.
  • a bucket is understood to be a container having a circumferential cylindrical wall, which is generally slightly conically inclined, and an opening which typically extends over the entire upper side of the bucket.
  • the basic shape of the bucket which typically corresponds to the basic shape of the soil, is arbitrary.
  • the bucket may, for example, have an oval, round, rectangular or square basic shape.
  • a bucket is also understood to mean a can-shaped container.
  • the container In the region of the opening, the container typically has a circumferential edge on which an engagement region for cooperation with the cover is formed.

  • Containers containing liquids or dangerous goods must not only be permanently sealed sealable, they must be able to maintain the tightness even under external forces acting.
  • a container for the storage of dangerous goods with UN approval must For example, consist of a drop test in which the sealed container is dropped with its contents from a height of for example 1.80 m. If such a container hits the bottom with a tension ring, there is a risk that the tension ring will deform and that deformation will transfer to the container and lid, causing the container to leak.

  • latching elements or a latching edge for fastening the securing ring to the edge of the container are formed on the side wall.
  • the force in the radial direction, which is exerted by the edge of the container on the retaining ring not large enough to secure the locking ring safe to transport to the container. Therefore, latching elements or a (substantially) completely circumferential latching edge are used to prevent the circlip pushed onto the lidded container from being inadvertently released by external forces, i. is typically pulled upwards.
  • the locking ring can be fixed without the provision of locking elements on the container. In this case, locking elements may possibly be attached to the container in order to fix the retaining ring on the container.
  • the locking elements or the locking edge thus secure the retaining ring against unintentional lifting from the container.

  • the recesses are essentially limited to the peripheral region along the side wall, along which extends a respective latching lug or a latching element.
  • the recesses which are mounted above the locking elements typically attached to the lower edge of the securing ring, reduce the rigidity of the securing ring in the vicinity of the locking elements. In this way, the elastic deformability of Circlip increases in the region of the locking elements, so that they can dodge when pushing the locking ring on the container to the outside until the locking lugs have reached their locking position.
  • an operator can press through the recesses against the container while the detents are released from their detent position to exert a lever effect and thus lift the retaining ring from the container.

  • the retaining ring 6 More precisely the U-shaped portion 24 of the securing portion 8 of the container 2 disposed upside down, a bearing surface 52 which is formed on the upper side of the middle leg of the U-shaped portion.
  • the stacking area 40 of the securing ring 6 protrudes into an opening 53 , which is formed on the upper side of the further container 2a.
  • a container 1 has been described with a locking ring 6, which is formed from plastic.
  • plastic as a material for the circlip 6 is due to the elastic properties, in particular with regard to the possibility of deformation, when pushing and pulling the locking ring 6 on the edge 10 of the container 2 advantageous. But it is also possible to produce the retaining ring 6 of other materials, such as metal.
  • Fig. 21a, b show a locking ring 6, which was made of rolled metal.
  • the circlip 6 also has a self-contained, circumferential side wall 7, are formed on the recesses 30 for the support points 28 of a support bracket 29.
  • the Circlip 6 also has a self-contained, circumferential and inwardly over the side wall 7 projecting securing area 8.
  • a latching edge 55 is formed to the retaining ring 6 at the edge of a in Fig. 22a, b shown container 2 to fix.
  • the inwardly beyond the side wall 7 projecting securing area 8 has a substantially U-shaped portion 24 which engages around the lid 5 and this secures the container 2.
  • a depression 56 is formed directly next to the U-shaped subregion 24, which forms a bearing surface 22 for supporting a further securing ring 6a, more precisely its locking edge 55.
  • both two retaining rings 6 and two or more provided with retaining rings 6 container 1 can be stacked.
  • the securing ring 6 can in particular serve to cover an opening tab 57 formed on the edge 10 of the container 2, which in FIG Fig. 22a is shown on the upper container 2a.
  • the locking edge 55 by means of a tool from engagement under the skirt 11 to solve.
  • Fig. 23a, b and Fig. 24a, b show circlips 6, which differ from the in Fig. 22a, b , and Fig. 23a, b essentially differ in that they have a stacking area 40, which, as in the above-described securing rings 6, the Plastic are connected to the security area 8, more precisely to the U-shaped portion 24 of the security area 8, connect and extend from the securing area 8 upwards and there have a support surface 41 for the bottom 3 of a (further) container 2.
  • An inner side wall 43 of the stacking portion 40 extends further down than the top of the U-shaped portion 24 to put the stacking portion 40 on the lid 5 of the container 1 secured to the circlip 6 and thereby to support, as shown in FIG Fig. 24b can be seen.
  • Fig. 24b is formed by the stacking area 40 a space for over the top of the lid 5 protruding components, for example in the form of Deckeladaptern 36.
  • the lid 5 and the container 2 are formed from plastic, since the elasticity of the plastic material simplifies the sliding of the metallic locking ring 6 onto the container 2.
  • the plastic material of the container 2, the lid 5 and possibly the securing ring 6 may in particular be polyethylene, polypropylene, polyamides, PET or polyolefins.
  • the securing ring 6 can also be produced as a composite or as a combination of plastics and, for example, metallic materials.
  • the U-shaped securing region 8 can be produced, for example, in the roll-forming method from tinplate, while the side wall 7 of the securing ring 6 is formed with the latching rim 55 or with the latching elements 9 and the possibly existing stacking region 40 made of plastic.
  • the expression of the plastic geometry and the connection with the metal component can take place during an injection molding process.
  • a high level of safety during transport of a container 1 can be achieved, which makes it possible to achieve the requirements for UN approval for hazardous substances.
  • the containers 1 described above are, in particular, accessible to bucket and canister filling systems, ie they can be filled manually or automatically and emptied again. In this case, if necessary, a substitution of wide-neck barrel applications take place, in which a cover is screwed on for transport protection or secured with a metallic clamping ring.
  • lid adapters 36 substitution of canister applications is possible, particularly when the lid adapters 36 are connected to the foil bags 54 described above.
  • the use of foil bags 54 is particularly advantageous for use in multi-component applications.
