Definitions

  • the invention relates to a container comprising: a container made of plastic in the form of a bucket with a bottom and a circumferential side wall, a lid for closing an opening formed on the container, the container having a circumferential engagement area with a clamping profile on its edge , which cooperates with a clamping profile on an inside of an edge of the lid to close the opening of the container, and a locking ring to secure the transport of the lid attached to the container in the form of a bucket, preferably made of plastic.
  • a bucket is understood to mean a container with a circumferential cylindrical, usually slightly conically inclined side wall and an opening which typically extends over the entire top of the bucket.
  • the basic shape of the bucket which typically corresponds to the basic shape of the bottom, is arbitrary.
  • the bucket can, 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 area of the opening, the container has a circumferential edge on which an engagement area for interacting with the lid is formed.
  • the engagement area has a clamping profile which cooperates with a clamping profile on the inside of the edge of the lid in order to ideally close the opening of the container in a sealing manner.
  • the container may have an opening tab that extends into the engagement area to facilitate removal of the lid for a user.
  • the action of external forces can inadvertently release the engagement between the lid and the container.
  • the opening tab can be inadvertently pressed in. If, in this case, another container dips under the lid and is subsequently moved upwards, as can be the case, for example, when a truck is cornering, the lid of the container is unintentionally lifted when the opening tab is pressed in.
  • a liquid-tight plastic bucket is described, the lid of which is held in a liquid-tight manner with its curved edge over a bead of the bucket reinforced by a metal ring and by a clamping ring.
  • Containers that contain liquids or dangerous goods must not only be permanently sealable, they must also be able to maintain their tightness even when external forces are applied.
  • a container for the storage of dangerous goods with UN approval must For example, pass a drop test in which the closed container and its contents are dropped from a height of, for example, 1.80 m. If such a container with a clamping ring hits the floor, there is a risk that the clamping ring will deform and that this deformation will be transferred to the container and cover, so that the container will leak.
  • the DE 89 10 359 U1 a container closure of a metal container is described, in which the clamping ring has an improved dimensional stability against externally acting deformation forces.
  • the two ends of the clamping ring are connected to one another by a turnbuckle.
  • the DE 94 17 502 U1 proposed to design the ends of the clamping ring in the manner of a toothing with connection elements which can be interlocked with one another in a form-fitting manner.
  • the DE 90 12 138 A1 describes a tension ring without a tension lock whose first end section, which has an opening, covers a second end section in the closed state of the tension ring, which has an eyelet that can be inserted through the opening when the tension ring is closed.
  • Opening device applied with an opening force. After pressing in the lid, the clamping ring is closed and the lid is pressed in, i.e. pushed onto the container.
  • CH 624 356 A5 describes a metallic container, the lid of which is sheared onto the filling end of the container by means of a band-shaped plastic hoop.
  • the plastic hoop is a so-called "open" hoop that can be injected like a linear band.
  • a hoop tab lock is used to attach the hoop to the container.
  • a closed, elastic ring is used to close the metal receptacle of a container.
  • the elastic ring is part of a lid which has a metal cover for closing the upper body opening of the metal receiving body.
  • the elastic ring has a closing part which protrudes downward and cooperates in a clamping or latching manner with an outwardly extending projection on the upper opening of the metal receiving body in order to close the cover on the receiving body.
  • the locking mechanism carried by a peripheral skirt of a container closure.
  • the locking mechanism comprises a pair of spaced apart support straps of flexible material that are interconnected by a bridging element.
  • a locking hook is disposed between the support straps and is carried by the bridging element.
  • the locking hook has a locking lug which protrudes in the direction of the circumferential skirt, wherein in the locked state of the locking mechanism the locking lug is suitable for locking against a container locking surface and is held there by the flexible nature of the straps and / or an elastic seal.
  • the invention is based on the object of providing a container with a locking ring which overcomes the disadvantages of the prior art.
  • the securing ring should guarantee a high level of transport security for the container and should be meaningfully integrated into modern logistics and filling processes.
  • a container of the type mentioned at the outset in which an annular side wall of the locking ring engages around an edge of the container and its locking area protruding inward over the side wall overlaps an edge of the lid, the side wall and / or the locking area of the locking ring in are closed, wherein on the side wall of the securing ring inwardly protruding over the side wall of the securing ring latching elements for fastening the securing ring to the edge of the container are formed, and wherein between the side of the side wall of the securing ring on which the inwardly protruding securing area is formed, and recesses are formed in the side wall of the locking ring for the locking elements.
  • a "self-contained" side wall or a self-contained securing area is understood to mean that the side wall or the securing area run continuously in the circumferential direction. This does not mean that no recesses can be provided on the side wall or on the securing area, but these do not have two free ends that can be connected to one another, as is the case with a metallic clamping ring - with or without a turnbuckle.
  • the side wall and the securing area of the securing ring are typically formed in one piece or in one piece.
  • the side wall has a predetermined dimension on its inside which is adapted to the dimension of the edge of the container, so that the side wall of the securing ring encompasses the edge of the container and usually the edge of the lid in particular in a form-fitting manner.
  • the side wall of the locking ring is typically flat against the edge of the container. In the case of a round container, the diameter of the inside of the locking ring corresponds approximately to the diameter of the outside of the edge of the container and of the lid, which is typically flush with the container at its outer edge.
  • the securing area overlapping the cover can in particular rest on the upper side of the edge of the cover when the securing ring is in its securing position.
  • a locking ring for the transport-proof closure of a container, which is typically pushed from the top of the container onto the edge of the container closed with the lid.
  • the securing area of the securing ring protruding inwards over the side wall secures the Lid against unintentional lifting from the container.
  • the securing ring is therefore not attached to the container by applying a radial force with a reduction in its diameter and is subsequently fastened to the container by means of a turnbuckle or by means of a toothing.
  • the securing ring therefore does not require a turnbuckle and also has no free ends which could inadvertently come loose when the container secured with the securing ring hits the floor.
  • the locking ring can be attached to conventional containers that have a container and a lid, without constructive changes to these containers having to be made for this purpose.
  • the locking ring more precisely the side wall, can in particular also serve to cover an opening tab provided on the edge of the container so that it cannot be pressed in unintentionally, which can result in unintentional detachment of the lid from the container.
  • the securing ring can be bounced onto the plastic container in the form of a bucket, in particular when the lid is attached to the container.
  • the locking ring can be pushed onto the container closed with the lid.
  • the securing ring can be bounced onto the container, that is to say it can be placed or pushed onto the container in a translatory manner, for which purpose a bouncing device is typically used in an industrial process.
  • the lid which is applied to the container and secured with the locking ring is typically also made of plastic.
  • the locking ring is typically made of plastic.
  • the metallic retaining ring is produced in a roll-forming process, it is typically necessary to permanently connect the two free ends of a roll-formed sheet metal by a joining process, for example by welding, in order to form a self-contained, one-piece retaining ring.
  • a joining process for example by welding
  • such joining is typically not necessary, ie there are practically no joints in such a securing ring.
  • Latching elements for fastening the locking ring to the edge of the container are formed on the side wall.
  • the force in the radial direction that is exerted on the locking ring by the edge of the container is not great enough to fix the locking ring on the container in a manner that is safe for transport. Therefore, locking elements or - in an example not according to the invention - a (essentially) completely circumferential locking edge are used to prevent the locking ring pushed onto the container with lid from being unintentionally loosened by external forces, ie typically being pulled off upwards.
  • the securing ring can also be fixed on the container without the provision of locking elements. In this case, you may be attached to the container locking elements to fix the locking ring on the container.
  • the locking elements thus secure the locking ring against unintentional lifting off the container.
  • several locking elements distributed over the circumference of the side wall can be provided on the locking ring, which interact with locking elements on the container, but this is not absolutely necessary: it is sufficient if locking elements are only attached to the locking ring, but not to the container .
  • the locking elements are typically attached to a side of the side wall of the locking ring facing away from the locking area.
  • the locking ring and / or the container is / are slightly elastically deformed so that the locking elements or the locking edge can be moved along the outside of the container until it reaches its locking position / en.
  • the locking elements can engage behind the edge of the container, more precisely an apron formed on the edge of the container, so that the locking ring cannot be lifted upwards. If a locking edge is not used according to the invention, the securing ring may not be easily detached from the container, ie usually not without the use of a tool.
  • locking elements it is possible to release and re-slide the locking ring onto the container or onto other containers multiple times, ie the locking ring can be used several times. But it is also possible with locking elements To make the clamping ring usable only once, as will be described in more detail below.
  • a respective latching element generally only extends over a relatively small area in the circumferential direction of the locking ring.
  • the latching elements can in particular be arranged uniformly in the circumferential direction, that is to say at equal intervals. Since the locking elements may have to be released individually by an operator (see below), it is beneficial if the number of locking elements is not too large. For example, a maximum of eight or a maximum of twelve locking elements can be attached to the locking ring.
  • the locking elements protrude inwardly over the side wall of the locking ring.
  • the latching elements in particular in the form of latching lugs, are preferably formed on a side of the side wall facing away from the protruding securing area in order to engage behind an apron formed on the edge of the container.
  • the edge of the container forms a double edge which has a skirt spaced from the side wall of the container.
  • the skirt typically adjoins the engagement area for fastening the lid, which is formed on the edge of the container.
  • stiffening ribs are typically provided which extend from the outside of the side wall of the container to the inside of the apron.
  • the locking ring more precisely the locking lugs, can engage behind the apron on its underside in the locking position in order to prevent the locking ring from being lifted upwards, for example when a buoyancy force is exerted on this or on the lid in the container the transported product acts. Due to the locking of the locking elements under the apron, it is not necessary to make structural changes for locking the locking ring to be carried out on the container, ie the locking ring can be applied to a conventional container with a lid.
  • Recesses are formed in the side wall between the side of the side wall on which the inwardly protruding securing area is formed and the latching elements.
  • the recesses are essentially limited to the circumferential area along the side wall, along which a respective latching lug or a latching element extends.
  • the recesses which are attached above the locking elements, which are typically attached to the lower edge of the locking ring, reduce the rigidity of the locking ring in the vicinity of the locking elements. In this way, the elastic deformability of the locking ring in the area of the locking elements is increased, so that when the locking ring is pushed onto the container, they can move outwards until the locking lugs have reached their locking position.
  • an operator can press against the container through the recesses while the locking lugs are released from their locking position in order to exert a leverage effect and in this way lift the locking ring from the container.
  • the recesses continue in the securing area protruding inward over the side wall and preferably protrude just as far inward as the latching elements.
  • the locking ring has no undercut in terms of its vertical direction, which corresponds to the demolding direction in a locking ring made of plastic by injection molding, despite the inwardly protruding locking lugs and can be demolded without the provision of slide tools.
  • engagement areas for applying a force directed to the outside of the side wall to the locking elements are formed on the side wall in the area of the locking elements, the engagement areas preferably protruding beyond the side of the side wall facing away from the securing area.
  • attack areas are formed on the side wall of the locking ring that allow an operator to apply an outward force to the locking elements, for example in the form of locking lugs, in order to remove them from the To release engagement with the container.
  • the areas of attack on the side wall of the locking ring protrude downward beyond the side wall, since the side wall typically does not extend downward beyond the double edge or the skirt of the container, so that typically only one under the side wall extending attack area on the inside of the side wall an outward force can be exerted.
  • the apron can be pressed inward in the area of the recesses, for example because stiffening ribs for stiffening the apron were dispensed with in the area of the locking elements of the locking ring, it is possibly also possible for an operator to loosen the locking elements and the locking ring can lift off without attack areas being formed on the side wall of the locking ring for this purpose.
  • a respective engagement area and a respective latching element are attached to a pivotable tab formed on the side wall.
  • the tab is attached to the side wall approximately at the level of the latching element or above it so that it can pivot.
  • the engagement area which is typically formed under the latching element, serves in this case as a lever area for pivoting the tab and thus the latching element to the outside, so that the latching element can be released from the latching position.
  • the latching element is elastically stretched outward beyond the edge of the container or the apron, so that the locking ring can be lifted upwards in the area of the latching element.
  • the tabs can be connected to the side wall of the locking ring, for example via film hinges.
  • the tabs can also serve as a tamper-evident feature, ie it can be seen whether a respective tab has been pivoted from a basic position running essentially parallel to the side wall in order to release the associated latching element from its latching position.
  • predetermined breaking points can be formed between the side edges of the tab and the adjoining side wall of the locking ring.
  • the predetermined breaking points can be formed by comparatively thin material points between the edges of a respective tab and the side wall of the locking ring.
  • the predetermined breaking points can be broken open by folding up the flap from the basic position.
  • the recesses are designed for the engagement of the engagement areas protruding beyond the side wall of a further (structurally identical) securing ring which is placed on the securing ring.
  • the cutouts can have an essentially V-shaped geometry and the side edges of the areas of attack can be aligned at an angle to the vertical axis of the side wall. In this way, the engagement of the engagement areas of the upper locking ring in the recesses of the lower locking ring is simplified.
  • the width of the Recesses can in particular be adapted to the width of the attack areas, so that the recesses are used for laterally contacting the attack areas.
  • the side wall ends on its side facing away from the securing area at a distance of less than 10 mm, preferably less than 5 mm, below the latching elements or the latching lugs.
  • the distance between the underside of the side wall and the underside of the locking elements is reduced to a manufacturing-related (for example, for the plastic to flow together), the necessary distance is reduced and thus the area of attack for an operator is also minimized, in order to prevent the operator from being able to detach the locking elements located in the locking position from the edge of the container.
  • the distance required for confluence typically increases with the size of the container.
  • the locking lugs are used to (ideally not releasable) locking the lid on the container.
  • Such a lock is advantageous in the case of disposable or disposal containers, for example for medical waste or the like.
  • the side wall can terminate almost flush with the rest of the side wall in the area of the locking lugs, ie the attack areas protruding downward are dispensed with.
  • the recesses provided above the locking elements can optionally be dispensed with, provided that these are not required in order to ensure the required elasticity of the securing ring when it is pushed onto the container.
  • the locking elements can in this case in particular free ends in the manner of Have barbs to lock the locking ring to the container.
  • recesses for receiving mounting points of a support bracket of the container can be formed.
  • the two ends of the support bracket typically extend outward at the mounting points from the edge of the container or the apron, which is why the recesses in the locking ring are required.
  • the recesses are typically open to the lower side of the side wall facing away from the securing area, so that the securing ring can be placed on the container from above.

  • the orientation of the locking ring when it is placed on the container is specified by the recesses for the support bracket. The specification of an orientation of the locking ring in relation to the container can be advantageous, as will be described in more detail below.
  • the securing ring can have at least one predetermined breaking element, in particular a tear tab, for irreversibly severing the self-contained side wall and / or the self-contained locking area.
  • a tear tab By tearing off the tab, the side wall of the securing ring or the securing area is separated, ie the side wall or the securing area has two free ends after the opening.

  • the engagement openings 46 serve to lift the stacking ring 40 from the securing area 8 of the securing ring 6. This can be beneficial, for example, when filling material is to be emptied from the container 2 via the pouring opening 39 formed on the cover adapter 36.
  • Figures 14a, b show a locking ring 6 on which a further, structurally identical locking ring 6a is stacked.
  • the locking ring 6 is as in Figures 12a, b and has a stacking area 40.
  • the two retaining rings 6, 6a are here based on the above in connection with Figures 7a, b stacked one above the other, ie the upper locking ring 6a rests on the bearing surface 22 of the lower locking ring 6 and a respective engagement area 18 of the upper locking ring 6a engages in a recess 17 of the lower locking ring 6.
  • Figures 15a, b show two circlips 6, 6a stacked on top of each other, in which, in contrast to the one in FIG Figures 14a, b
  • a cover 5 is held, specifically to the above in connection with Figures 8a, b described way.
  • the upper securing ring 6a does not lie with the underside of the circumferential side wall 7, but rather with the underside of the engagement areas 18 protruding downward over the side wall 7 on the bearing surface 22 of the lower securing ring 6, ie the upper securing ring 6a is opposite the in Figure 14a shown upper locking ring 6a rotated in the circumferential direction.
  • the free space between the two stacked securing rings 6, 6a is increased in order to create sufficient space for receiving the preassembled cover 5.
  • the height of the collar area 44 of the stacking area 40 is selected such that the cover 5 held in the upper securing ring 6a rests on the top of the collar area 44, ie the top of the collar area 44 forms a support surface for the cover 5 of the upper securing ring 6a.
  • stiffening elements 47 are formed, which are designed in the form of stiffening ribs. Between two adjacent stiffening elements 47, a free space 48 is formed which has a width selected so that the downwardly protruding engagement area 18 of the upper securing ring 6a stacked on the securing ring 6 is fixed in its lateral position.
  • the free space 48 can, for example, be adapted to the width of a respective latching element 9 protruding inwardly beyond the side wall 7, which latching element is formed on the inside of the engagement area 18, so that the latching element 9 can engage in the free space 48 with as little play as possible.
  • the shape of the stiffening elements 47 can also be adapted to the shape of the latching elements 9 or the engagement areas 18 in order to achieve a lateral fixation during stacking.
  • Fig. 16 shows a container 1 which has a stacking area 40 which is formed in one piece with the securing area 8.
  • a pouring trough 49 is formed on the stacking area 40. If the cover adapter 36 is correctly aligned with the securing ring 6 with the aid of the indexing described above, the container 2 can be emptied precisely via the pouring trough 49.
  • Fig. 17 shows a container 1 in which a band-shaped support bracket 50 is formed on the securing ring 6 and is fastened to two mounting points 51 on opposite sides of the securing ring 6.
  • the support bracket 50 is also made of plastic and is manufactured in one piece with the securing ring 6.
  • a support bracket 29 which is attached to the mounting points 28 on the outside of the edge 10 of the container 2.
  • Fig. 18 shows a container 1 with a securing ring 6, which has a cover area 58 protruding downward beyond the inwardly protruding, annular securing area 8.
  • the cover area 58 adjoins the securing area 8 radially inward and has a circumferential, conical side wall which protrudes downward beyond the U-shaped securing area 8 and is planar, extending horizontally Direction extending cover surface 59 merges.
  • the planar cover surface 59 is at the level of the cover surface and completely covers a trough-shaped partial area 60 of the cover 5 that protrudes downwards and extends into the interior of the container 2.
  • the securing ring 6 with the cover area 58 thus overlaps in the case of the in Fig.
  • An intermediate space 61 is formed between the cover surface 59 at the level of the cover surface and the top of the trough-shaped subregion 60, in which objects, for example tools, which are useful for an operator of the container 1 can be stored.
  • cover area 58 or the cover surface 59 does not have to completely cover the trough-shaped partial area 60, but that in certain applications a partial cover is sufficient.
  • the cover area 58 can also be used to cover one or more partial areas 60 of the cover 5 which protrude downward and which have a geometry deviating from a trough-shaped geometry.
  • the cover area 58 can be molded onto the securing area 8, as shown in FIG Fig. 18 is shown, but a detachable attachment to the securing area 8 or to its U-shaped sub-area 24 is also possible, as was described above in connection with the stacking area 40.
  • Fig. 19 shows a container 1 which differs from the container 1 described further above essentially in that it has a rectangular basic shape and in that two cover adapters 36 are attached to the cover 5 of the container 1.
  • the securing ring 6 has a stacking area 40 in order to stack two or more of the containers 2 on top of one another.
  • Figures 20a, b show the in Fig. 19 shown container 2, in which the rotary closures 37 have been removed from the lid adapters 36, in a position placed upside down on the top of the side wall 4 of a further, empty container 2a.
  • the securing ring 6 more precisely the U-shaped sub-area 24 of the securing area 8 of the upside-down container 2, has a bearing surface 52 which is formed on the top of the middle leg of the U-shaped sub-area.
  • the stacking area 40 of the securing ring 6 protrudes into an opening 53 which is formed on the top of the further container 2a.
  • the contents of two foil bags 54 which are connected to the lid adapters 36 and stored in the container 2, can be emptied into the further container 2a at the same time, which is advantageous for multi-component applications .
  • a container 1 was described with a locking ring 6 made of plastic.
  • the use of plastic as the material for the securing ring 6 is advantageous because of the elastic properties, in particular with regard to the possibility of deformation, when the securing ring 6 is pushed onto and off the edge 10 of the container 2. But it is also possible to produce the locking ring 6 from other materials, for example from metal.
  • Figures 21a, b show a locking ring 6 not according to the invention, which was made from rolled metal.
  • the securing ring 6 also has a self-contained, circumferential side wall 7 on which recesses 30 for the mounting points 28 of a support bracket 29 are formed.
  • the Securing ring 6 also has a self-contained, circumferential securing area 8 protruding inwardly beyond the side wall 7.
  • a locking edge 55 is formed in order to secure the locking ring 6 on the edge of an in Figures 22a, b to attach the container 2 shown.
  • the securing area 8 protruding inwardly beyond the side wall 7 has an essentially U-shaped partial area 24 which engages around the cover 5 and secures it on the container 2.
  • a trough 56 is formed which forms a support surface 22 for supporting a further securing ring 6a, more precisely its locking edge 55.
  • both two retaining rings 6 and two or more containers 1 provided with retaining rings 6 can be stacked one on top of the other.
  • the securing ring 6 can in particular serve to cover an opening tab 57 formed on the edge 10 of the container 2, which is shown in FIG Figure 22a is shown on the upper container 2a.
  • FIGs 23a, b and 24a, b show circlips 6 not according to the invention, which differ from the in Figures 22a, b , and Figures 23a, b
  • the locking rings 6 shown differ essentially in that they have a stacking area 40 which, as in the case of the locking rings 6 described above, which consist of Plastic, adjoin the securing area 8, more precisely to the U-shaped sub-area 24 of the securing area 8, and extending upwards from the securing area 8 and having a support surface 41 there for the bottom 3 of a (further) container 2.
  • An inner side wall 43 of the stacking area 40 extends further down than the top of the U-shaped sub-area 24 in order to place the stacking area 40 on the cover 5 of the container 1 secured with the locking ring 6 and thereby support it, as shown in FIG Figure 24b can be seen.
  • the stacking area 40 forms a free space for components protruding beyond the top of the cover 5, for example in the form of cover adapters 36.
  • the lid 5 and the container 2 are made of 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, if applicable, the securing ring 6 can in particular be polyethylene, polypropylene, polyamides, PET or polyolefins.
  • the locking ring 6 can also be produced as a composite or as a combination of plastics and, for example, metallic materials.
  • the U-shaped securing area 8 can be produced from tinplate, for example by roll forming, while the side wall 7 of the securing ring 6 with the locking edge 55 or with the locking elements 9 and the possibly existing stacking area 40 are formed from plastic.
  • the shape of the plastic geometry and the connection with the metal component can take place during an injection molding process.
  • a locking ring 6 can be used to achieve a high level of safety when transporting a container 1, which makes it possible to meet the requirements for UN approval for hazardous substances.
  • the containers 1 described above are particularly machine-compatible on bucket and canister filling systems, i.e. they can be filled and emptied again manually or automatically.
  • wide-neck drum applications can be substituted, in which a cover is screwed on to secure transport or secured with a metal clamping ring.
  • cover adapters 36 a substitution of canister applications is possible, in particular if the cover adapters 36 are connected to the film bags 54 described above.
  • the use of foil bags 54 is particularly advantageous for use in multi-component applications.
  • the use of a securing ring 6 with a stacking area 40 ensures good residual emptying capacity despite the cover adapter 36, since no indentations have to be provided in the base 3 of the container 1 for receiving the cover adapter 36.
