EP2036838B1 - Lid assembly for a fluid container - Google Patents

Description

The invention relates to a lid arrangement for a container for liquids, which has a downwardly directed areawise oblique edge, in regions according to the preamble of claim 1.

From the GB 2 372 194 A a generic lid assembly for a commercial garbage container is known with a specially designed lid, wherein a seal between two peripheral edges of the lid is arranged both edges embrace a protruding peripheral edge of the container opening. So that the lid can not jump open, it is secured by three acting in the manner of toggle fasteners locks. These connect the lid to the container, wherein a ring is hinged by means of a flange movable on the lid and engages behind a riveted hook on the container.

In the DE 203 04 131 is described a container for collecting waste, wherein the lid by means of a resilient locking hook in his Closed position unlockable is blockable. It is also disclosed that "the locking hook is formed on the cover and [...] equipped with a projecting locking web, which engages behind a bead or reinforcing strip integrally formed on the upper edge of the container body". The locking hook is located centrally on the edge opposite the lid hinges.

From the state of the art is still known in tool boxes or order tons to provide cover assemblies mounting brackets, which are held by bolts. To accommodate the bolts usually brackets are provided on the cover assembly. The mounting brackets are thus rotatable about the axis of the bolt. It is also known to provide lateral projections on mounting brackets as a replacement for a bolt, which engage in corresponding receptacles on the cover assembly. The mounting brackets can then rotate around the lateral projections. A disadvantage of the known prior art is that for attachment or for releasing the lid assembly to or from a container, it is necessary to rotate and engage each individual mounting bracket to the bolt or the projections. It is also disadvantageous in particular with tons with the described fastening clips that they are distributed over the entire circumference at regular intervals, so that a considerable amount of work is required until all the fastening clips are closed.

Based on the state of the art GB 2 372 194 A It is an object of the invention to provide a liquid-tight lid assembly on a container which is easy to open and close in a short time.

• mit einem Deckel, der mittels Scharnierarmen, die sich zu einer an dem Behälter angeordneten Halteeinrichtung erstrecken, an dieser Halteeinrich-tung am Behälter drehbar gehalten ist, und
• mit mindestens zwei Befestigungskiammern zum Befestigen des Deckels an dem Behälter, wobei zwei Befestigungsklammern seitlich an zwei gegenüberliegenden Deckelseiten angeordnet sind vorgeschlagen, wobei die Aufgabe dadurch gelöst wird, dass die zwei Befestigungsklammern einstückig an dem Deckel im Vorderbereich ausgebildet sind, sich aus der Deckelebene in Richtung des Behälters erstrecken und ein hakenförmiges freies Ende aufweisen, wobei

das jeweilig hakenförmige freie Ende der Befestigungsklammern eine Schräge aufweist, die die jeweilige nach unten gerichtete schräge Kante am Behälter hintergreift.It is a lid assembly for a container for liquids, wherein the container has a downwardly directed partially sloping edge,

• with a lid, which by means of hinge arms, which extend to a holding device arranged on the container, at this Halteeinrich-device is rotatably supported on the container, and
• with at least two mounting clamps for attaching the lid to the container, wherein two mounting brackets are arranged laterally on two opposite sides of the cover proposed, the object is achieved in that the two mounting brackets are integrally formed on the cover in the front region, from the lid plane in the direction extend the container and have a hook-shaped free end, wherein

the respective hook-shaped free end of the mounting brackets has a slope which engages behind the respective downwardly directed oblique edge on the container.

The present lid assembly is particularly beneficial when used on tons that can be used to dispose of waste liquids, including fats or oils. It is advantageous that the lid has two mounting brackets in the front region of the lid, which are integrally formed on the lid. Due to the one-piece design, it is possible for the user of the lid assembly of the invention to close without additional measures the lid by a simple downward pressing. The integrally formed on the cover mounting brackets are also in a handle to solve again. In a preferred embodiment, the lid assembly is made of plastic, for example by injection molding, so that the mounting brackets formed thereon are molded on could be.

Furthermore, it is favorable that the cover assembly of the invention can be placed on existing, standardized containers, such as garbage bins. Garbage bins are made in accordance with EN 840 so that the lid assembly of the invention is applicable to all such barrels. Preferably, the two laterally disposed mounting brackets extend downwardly from the lid over an upper peripheral edge of the container Fig. 1 negative Z-direction) to one at the upper peripheral edge of the barrel down or possibly in a non-standard tons possibly also to the side (in Fig. 1 X-direction) behind the protruding edge.

The mounting brackets are elastically bend outward and snap in a closed position of the lid with their hooked ends behind the edge in a closed position. To close the lid so it is only necessary to push the lid down until the mounting brackets engage. To open the lid, the mounting brackets are pushed outward with hand force and simultaneously moved upward, so that the latching connection of the mounting brackets is released at the peripheral edge of the barrel. Due to the elasticity of the mounting brackets, the closed position can be repeated as often as desired.

It is also advantageous that at least one fastening arm is provided on the cover arrangement, which extends over a predetermined length over the surface of the lid and is simultaneously supported on the holding device of the container or is guided thereon. The attachment arm can be formed integrally with the cover assembly or attached as an additional part in retrospect. By at least one mounting arm is an additional safeguard against accidental opening of the lid, especially at peak loads ensured by sloshing against the lid liquid.

In a particular embodiment, the lid assembly of the invention may additionally have an apron, which projects into the container. In a particular embodiment, the skirt may have a fit to the inner wall of the container. The apron projecting into the container serves, in particular, to prevent a liquid bouncing against the lid assembly with great force (for example when the container falls over) from acting completely on the lid seal, but largely absorbed by the apron extending in the circumferential direction along the inner wall of the container becomes. In an alternative embodiment, the skirt may be slightly spaced from the inner wall of the container. It then makes sense to provide an additional seal between the inner wall of the container and the apron. It is also possible for the part of the skirt facing the container to be shorter in order to ensure easier opening and closing of the lid. Alternatively or additionally, this front skirt part can also be elastically movable, so that it can always rest against the inner wall of the container. For this purpose, it could also be provided to slit the corners of the apron in the front area. By means of the apron, the lid assembly an additional safeguard against accidental opening of the lid and thus the unwanted escape of liquid, since the apron on the inner wall generates a frictional resistance. The tightness is particularly advantageous for the transport of dangerous goods such as waste oil.

The lid assembly is also sealed over its outer edge against unwanted liquid leakage. For this purpose, the lid arrangement has a downwardly directed groove which extends over a rim extending upwardly from the container. To ensure the tightness within this groove a seal, preferably a rubber seal is arranged. In a particular embodiment, the groove may be formed differently deep over its length, so that the seal arranged therein at different locations at different depths in the groove. In this way, from the projecting into the groove edge of the container, which has a constant height, at different points of the seal a different pressure force exercised, which leads to special tightness over the entire circumference of the lid assembly. In a preferred embodiment, the groove on all four Rare the lid assembly may be evenly cambered. Preferably, the camber on each longitudinal side may have a size of 2 to 5 mm. In a favorable embodiment, the skirt may be an extension of the inner web of the groove.

To stabilize and stiffen the lid, it is particularly advantageous to provide reinforcing struts on the underside of the lid, which can be integrally formed with the lid. The reinforcing struts can be formed in any pattern, for example star or cross-shaped.

Particularly advantageous is the use of the lid assembly on conventional, standardized containers, such as refuse, so that no additional costs incurred for the development of new tons and equipment.

In Fig. 1 the lid assembly 1 of the invention is shown on a like a garbage bin container 2 in a perspective view obliquely from above. The cover assembly 1, preferably made of plastic, can be placed on the container 2 and fastened thereto with two fixing clips 3 integrally formed on the cover assembly 1. From a cover 4 of the lid assembly 1, hinge arms 5 extend outwardly in the direction (Y direction) of a holding device 6 provided on the container 2 and are connected thereto. The connection of the hinge arms 5 to the holding device 6 is provided by hinge pins 6 ", which are pressed from the side through openings 5 'of the hinge arms 5 into bores 6' of the holding device 6. The cover 4 is, as is known from commercial garbage cans. to open by a rotational movement about the holding device 6.

The integrally formed on the lid 4 of the lid assembly 1 mounting brackets 3 extend from the lid 4 initially in the X direction to the outside, form an arc around the edge of the lid assembly 1 and continue to extend substantially vertically in the Z direction down to over its length to overlap both the lid assembly 1 and the upper edge of the container 2. At its free end 3 ', the mounting brackets 3 have a hook shape (see. Fig. 2 ), with which they engage behind an edge with an oblique edge of the container 2. In the illustrated embodiment, the lower edge of the mounting brackets 3 is chamfered in the Y direction. The Befestigungsklammem 3 are preferably made of plastic and elastic, so that they can bend when closing the lid 4, when they slide over the outer edge of the container 2, to the outside and then the edge or the edge or the like of the container 2 alone can engage behind by their elastic restoring force as soon as the closed position of the lid 4 is reached. To open the mounting brackets 3, the lid is first pressed down and then the hook-shaped ends 3 'bent with hand force to the outside and the lid 4 simultaneously moved upwards. The depression is made possible by a flexible soft seal between cover and barrel explained in more detail below. To stabilize the lid 4 and the fastening clips 3 formed thereon, one or more reinforcing ribs 4 'extending over at least part of the circumference of the lid 4 are provided. The fastening brackets 3 adjoin the reinforcing rib 4 ', so that the elastic forces of the fastening brackets 3 can also be supported by the reinforcing rib 4' at the rear, ie toward the center of the lid.

In addition, at least one fastening arm 7 is provided in the lid assembly 4, which extends over a predetermined length of the rear part of the lid assembly 1 in the Y direction. The mounting arm 7 is integrally formed with the cover 4 and supported and guided on the rear side of the holding device 6 designed as a rod. As a result, an additional assurance of the closed position of the cover assembly 1 is ensured. At the same time, the load occurring on load on the cover assembly 1, the force occurring on the mounting arm 7 and thus indirectly distributed to the holding device 6.

Fig. 2 shows the lid assembly 1 in a perspective view obliquely from above. The lid 4 of the lid assembly 1 is closed. In the embodiment shown, in each case one fastening clip 3 is provided on the cover 4 in the front region on the left and right sides. In addition, it would also be possible in the front area, for example centrally, to provide an additional fastening clip 3 (indicated by dashed lines) corresponding to the lateral fastening clips 3. The fastening clips 3 have lateral stiffeners 3 "on their side edges, which ensure the necessary rigidity and stability for securely holding the engagement position of the hook-shaped free ends 3 ' (see. Fig. 1 ) engages and is supported on this. By matching the holding device 6 form a rotational movement of the lid 4 to the holding device 6 is not hindered. Further, in this embodiment, the lid assembly 1 has a downwardly directed skirt 8, which is insertable into the interior of a container 2. Preferably, the skirt 8 is integrally formed on the lid assembly 1 and dimensioned so that it rests against the inner wall of the container 2 in a fit. Thus, high, acting on the lid assembly 1 forces of the liquid in the container 2 (for example, when the container 2 falls over) also distributed to the skirt 8 and excessive pressure on the ceiling seal can be safely avoided. Preferably, the skirt 8 has a depth (in the Z direction) of 10 to 150 mm, more preferably 70-100 mm.

Fig. 3 shows the lid assembly 1 in a perspective view obliquely from below. At its outer edge, the cover assembly 1 has a downwardly directed groove 9, in which a seal 10, preferably soft seal, extends from a suitable elastomer. The groove 9 is formed so that it can be placed on a container 2 upwardly extending edge and thus a seal of the lid assembly 1 relative to the interior of the container 2 is ensured. In a particular embodiment, the groove 9 is cambered over its length sections, ie different deep, so that the seal 10 extends unevenly deep within the groove 9. For example, it may be provided that the groove 9 in the region of the mounting bracket 3 and on the back in the region of the mounting arm 7 is formed to be less deep in order to increase the pressure forces on the seal 10 in these areas. Thus, a particularly good tightness of the cover assembly 1 can be achieved. For its stabilization or stiffening, the cover 4 on its underside reinforcing struts 11. Thus, the lid 4 does not deform under load and fits exactly on the provided on the container 2 edge. In the embodiment shown, a plurality of reinforcing struts 11 are provided in a cross-over shape, but any other arbitrary pattern is possible as long as the lid 4 is sufficiently stiffened.

In Fig. 4 the lid assembly 1 of the invention is shown on a container 2 in a view from above. Here, it is easy to see how the mounting brackets 3 overlap the outer edge of the container 2 and engage with their hook-shaped free ends 3 'an edge of the container 2.

In Fig. 5 the lid assembly 1 of the invention is shown in a further embodiment in plan view. The lid 4 in this case has two arranged in the rear region of the mounting arms 7, which guide the lid 4 when opening and closing on the holding device 6 and support it at loads. The reinforcing rib 4 'extends over the entire circumference of the lid 4 and provides additional stabilization for the fastening arms 7.

Fig. 6 is a sectional view taken along the line A - A in Fig. 5 , The cover 4 in this case has a downwardly open groove 9, in the circumferential direction, a seal 10 extends. The groove 9 is formed by two downwardly directed webs 9 ', 9 "The outer web 9' has a length such that it securely engages over the upwardly protruding edge of the container 2, but at the same time to the upwardly directed outer edge of the container 2 is also spaced in the closed state of the lid 4. The inner web 9 "is shown in the Extended design and forms the projecting into the container 2 skirt 8. In this way, contamination of the edge region is reliably prevented Preferably, the skirt 8 is formed thin, that is, that it has a thickness of about 2-10 mm.

Fig. 7 shows the lid assembly 1 in a side view. The circumferentially extending groove 9 is cambered in this embodiment at the respective longitudinal sides. The camber preferably has a height of 2-4 mm. In this way, a particularly good seal is achieved because the running in the groove 9 seal 10 is pressed firmly against the upstanding edge of the container 2.

Fig. 8 shows a sectional view of the lid assembly 1 according to another embodiment. The characteristics are essentially the same as those of the Fig. 6 However, the webs 9 ', 9 "of the groove 9 are the same length The skirt 8 is arranged as an additional element in the interior of the lid 4 and spaced from the inner web 9". For sealing between the skirt 8 and the inner wall of the container 2, a circumferentially extending seal 12, preferably a rubber seal, is provided. Such a seal can be plugged with a Einstecknut on the edge of the skirt and press with a laterally molded thereto sealing bead against the container wall. The larger the distance between the skirt 8 and the groove 9, the longer the skirt 8 can be. In Fig. 8 not explicitly shown, however, it can be provided that the part of the apron 8 which points forwards in the direction of the container 2 and extends in the Z-direction is shorter. This front skirt portion may also be elastically movable and provided at the corners with a slot 8 '. Thus, this skirt part can be manually pressed in the Y-direction when opening the lid 4 and a secure concern in the closed state at the front inner wall of the container 2 can be ensured due to its elasticity.

It is expressly noted that all different feature elements the individual embodiments can be combined with one another as far as is technically possible and there is no contradiction. So it is z. B. possible, even with a voltage applied to the inner wall of the container skirt according to Fig. 6 an additional seal 12 according to Fig. 8 provided.

How out Fig. 9 can be seen, the features as in connection with the embodiments of a lid in the Fig. 1 to 8 are described with particular advantage in a lid for a ball bottom container 20 used. A ball bottom container 20 is in an excellent manner for the absorption of hot fluids, since a strength of the container is ensured even with hot content materials due to the special structure that arises as a result of the combination square container top with ball bottom. This strength is further increased by the tension of the lid in the opening, so that a bulging of wall areas in equipped with lids globe bottom containers.
