Description

The present invention relates to a container, in particular plastic container, preferably in the form of a bucket, with a lid for closing the container, which has a receiving area, in which the container opening bounding edge of the container is engaged and held in the closed state, wherein the receiving area of the Lid and on the edge of the container opening against each other acting locking elements and sealing surfaces are provided, wherein the locking elements are designed so that in the closed state of the container, the sealing surfaces securely against each other and seal, wherein the receiving portion of the lid has a constriction, which forms a film hinge, the a lower segment is formed, wherein at least two differently acting and stacked locking element pairs are provided on the lower segment and the edge of the container opening, of which at least one locking element pair is formed so that the Lösu ng the latching would have to be done with different, in particular opposite movement than the other locking element pairs, so that a movement of at least a portion of the receiving area of the lid or the edge of the container opening to solve the locking differently acting locking element pairs in different directions, in particular opposite would have to be done

Containers for the safe transport of liquid or pasty hazardous substances have long been known. These containers have in common that on the one hand they must have sufficient tightness to prevent the escape of the transported hazardous substances. On the other hand, you must also have a closure that ensures a safe closing of the container even under extreme loads. In particular, such containers and their closures must withstand a load that can also occur in case of accidents, such as dropping the container from a certain height.

From the prior art are known for such containers, in particular buckets or barrel-like container whose lid is screwed firmly with a screw. To secure additional metallic brackets may be provided which press the lid on the container or prevent loosening of the screw cap. Furthermore There are closure systems in which the lid is flanged after application to the container according to achieve tightness. In addition, systems are known in which the lid or closure is glued or welded or in which additional sealing films are glued or welded. From the international patent application WO 01/19697 A1 a container with a lid is known, which has a receiving area for an upper edge of a container. At this receiving area a constriction is provided so that a releasable from the container lid segment is formed. The segment and the edge of the container opening have two differently acting and superimposed locking element pairs, of which a locking element is designed so that the solution of the locking must be done with different, in particular opposite movement. The CH 672 473 A5 shows a container with a lid on which a tear strip is arranged. At this tear strip, however, there are no means to ensure a secure closure between the lid and container. In the further state of the art is on the US 5,979,691 to point.

All these containers or closure systems have the common disadvantage that they are complicated and complicated to handle, in particular taking into account the requirement of a largely automated treatment of such objects and thus also of the closing operation.

It is therefore an object of the present invention to provide a tight and secure sealable container which is suitable for the transport of liquid or pasty hazardous substances, both the production and the handling should be inexpensive and effective.

This object is achieved in that at least two locking element pairs are provided on the outer leg of the U-shaped receiving portion of the lid and in the form of undercuts on the edge region of the container opening and the outer leg of the receiving portion of the lid has the constriction, wherein a locking element of a first pair of locking elements is arranged at a lower outer end of the segment and a locking element of a second locking element pair at an upper inner end of the segment, in close proximity to one on the inside of the outer leg trained groove is arranged, in which the provided on the edge locking element of the second locking element pair can additionally engage .. Advantageous embodiments are the subject of the dependent claims.

The container according to the invention, which is preferably in the form of a bucket or in a barrel-like shape, has a lid for closing the container, wherein the lid has a receiving area, in which engages the edge of the container opening of the container in the closed state and held there , In that regard, the container of the invention starts from known containers.

However, the present invention proposes a completely different way from the prior art in order to achieve the present object. The basis of the container according to the invention is the recognition that a secure and tight sealing of a container is made possible by the provision of positively locking interconnected latching elements and correspondingly cooperating sealing surfaces. By the use of form-fitting connections by means of locking elements and corresponding sealing surfaces ensures that both the handling and the production are kept simple. This ensures effective use of the container.

Preferably, the positive connections of locking elements are formed so that the lid of the container can only be solved if at least part of the lid or a part of the container is destroyed. This is a verifiable Erstöffnungsgarantie given to the user, since only a never opened container is intact, while a container already opened once has damage to the lid or the container.

According to one embodiment of the container, the receiving area of the lid and the edge of the container opening which engage in closing, or the latching elements which form the positive connection, and the sealing surfaces are designed so that the placement of the lid or the closing of the Container takes place by a translational movement of the lid to the container. In particular, it is advantageous if the lid is merely pushed or clipped onto the container from above. This allows a automatic closing of the container by a machine, since a translational movement or the placement or clipping on a machine is easy to carry out.

According to the present invention, at least two, preferably three or more locking element pairs are provided on the receiving area of the cover or on the edge of the container opening, since a plurality of locking element pairs allow multiple security and thus contribute to the secure closing of the container. Under Rastelementpaaren not only two locking elements are to be understood here, which cause each other a form-fitting, but under certain circumstances, a plurality of locking elements, which, however, are considered due to their similar design and the same mode of action only as a pair of locking elements. For example, this applies to locking elements, which are formed only by a subdivision.

The at least two, preferably three or more locking element pairs of the container are designed such that at least one of these locking element pairs is so different from the other locking element pairs, that the movement to release the locking element pair is different from the other locking element pairs. This means that not all of the locking element pairs can be released at once by a single movement of a portion of the lid or the receiving area of the lid or the edge of the container opening. Rather, it is ensured by the different movement that is required to solve all pairs of locking element, that a complicated movement is necessary. In particular, it has been proven to provide at least two types of locking element pairs that require opposite movements to solve the locking. In particular, it is hereby thought that, for example, a part of the receiving area has to be moved to open both outwards and inwards. This is therefore in particular beyond that different, in particular opposite solution movements are required for circumferential locking elements on opposite sides. Rather, here different locking element pairs are meant, which are adjacent to each other, for example, arranged one above the other.

The provision of different types of locking element pairs, which differ by the different movement when releasing the locking, also has the advantage that in this way with elements for positive connection and a sufficient clamping action for the likewise provided on the receiving area of the lid or at the edge of the container opening sealing surfaces can be produced. Even if the pressure of the sealing surfaces against each other is already achieved by appropriate dimensioning of the lid and container opening, by providing different types of locking element pairs, as described above, an additional surface pressure, which can be safely maintained in many stress situations, guaranteed.

Preferably, in addition to separately arranged sealing surfaces may also be provided on the positive connection generating latching elements corresponding sealing surfaces, especially when using different types of detent element pairs with different directions of movement to release the locking and a mutual wedging can be effected, which leads to that in itself positive locking elements in a certain way are pressing together and thus form sealing surfaces.

According to a preferred embodiment, additional sealing means may be provided in the receiving area of the lid and / or at the edge area of the container, in particular in the form of inserted or injected sealing rings.

In order to realize the so-called first-opening guarantee, it may furthermore be advantageous to provide a predetermined separation point in the receiving area of the lid and / or at the edge of the container opening in order to be able to separate corresponding areas which ensure a secure and permanent connection in a simple manner. In particular, it is advantageous in this case to provide a predetermined separation point in the region of the receiving region or the edge of the container opening, which leads to that part of the receiving region and / or the edge being separated, which has the or the differently acting locking element pairs, since in particular this type Of locking element pairs can ensure that the positive connection is not solvable.

The receiving area of the lid has a substantially U-shaped cross-section, the receiving area being open at the bottom in order to receive the edge of the container opening from there. The thighs of the U-shaped receiving area then close the edge of the container opening and holds it by means of locking elements form-fitting firmly, while the sealing surfaces in close contact with each other, so as to ensure the sealing effect.

While it is of course possible to provide a variety of different combinations of latching hooks, latching noses, locking grooves and the like. As well as correspondingly designed sealing surfaces, the present invention in the U-shaped receiving area, which is formed by an outer and an inner leg, on the inside of the outer leg two locking lugs or hooks, which cooperate with two locking lugs on the outside of the edge of the container opening. Preferably, the outer leg of the U-shaped receiving portion on the outside of a further latching hook, which cooperates with an undercut of the edge formation of the container opening, which is provided in a double-walled part of the edge formation on the outer web of the edge. The arrangement of latching hooks or lugs both on the inside and on the outside of the outer leg of the U-shaped receiving area and the corresponding formation of corresponding undercuts or latching elements on the edge region of the container opening two different types of locking element pairs are formed by distinguish that the one type of locking element pairs can be solved in their latching when the outer leg is moved outwards, while the other type of locking element pairs requires movement of the outer leg inwardly to effect a solution of the latching.

By this simple per se design of the locking element pairs on the one hand ensures that the lid can be placed in a simple manner by vertical movement from top to bottom on the container and on the other hand causes this triple locking a secure arrangement of the lid on the container. The different nature of the locking element pairs with the opposite opening movements also ensures that the lid can not be removed without damage.

In order to allow easy opening of the container without the use of special tools special and to ensure easy placement of the lid, a constriction is formed in the outer leg of the U-shaped receiving area, so that forms in this area a film hinge, which forms a lower segment of the outer leg. On the one hand, this film hinge causes the lower segment of the outer leg to perform the corresponding movements in order to pass the locking lugs or hooks and undercuts when the container is closed or the cover is placed on top of it. In addition, the film hinge or the constriction provides the ability to separate the lower segment by simply cutting with a cutting tool, such as a knife along the film hinge. Since in the lower segment of the outer leg, the locking elements of the receiving area are provided to two different Rastelelementpaaren, remains after disconnecting only one catch left, which can be solved by correspondingly slight movement of the outer leg of the receiving area. At the same time, once the container has been opened for the first time, this unique locking mechanism allows the container to be used and reclosed without, however, ensuring safe closure with the first-opening guarantee.

In order to enable a uniform closure of the container, it is preferred if the locking elements or locking element pairs are arranged circumferentially around the container opening or to the lid, again a break or subdivision of a locking element through recesses, webs, etc. may cause a corresponding plurality of locking elements is formed, but in the context of the present invention, the purpose of the uniform closure and the treatment is maintained as a locking element or two locking elements in a locking element pair.

By the measures described above, it is possible in the container according to the invention to use conventional materials, without having to take special measures. Preference is given to plastics based on polyolefins, in particular polyethylene and polypropylene. The preferably additionally used sealants generally do not require any special requirements with regard to the selection of the material, although depending on the application, special requirements with regard to the selection of the material may nevertheless exist. Only the dimensioning of the components, for example, the wall thicknesses, must be adapted according to the application in order to bear the necessary forces even with special loads, such as accidents. According to a further embodiment, the container with the lid at internal pressures of up to 1 bar, in particular up to 0.8 bar, especially liquid and pasty substances safely and tightly sealed and meets in particular the United Nations approval conditions for the transport of liquid hazardous substances.

The Fig. 1 shows a side view with a partial cross-sectional view of a container 1 according to the invention in the closed state, ie with attached cover 2. In this state, the edge 3 of the container opening engages in the receiving portion 4 of the lid and is held firmly in this. The container 1 is in the illustrated embodiment of the form of a bucket on which a pivotable handle 27 is arranged for ease of carrying.

As in the partial sectional view of Fig. 1 can be seen, the container 1 has a slightly inwardly curved bottom 30 having support legs 31 at its outer edge, so that the bottom 30 is slightly spaced from the standing surface. The container 1 also has a slightly conical, but substantially cylindrical outer contour to allow nesting empty containers.

The Fig. 2 shows in its partial images a) to c) a detailed view of the cut-away area with the recording area 4 and the edge 3 of the container opening, in different stages of the closing of the container first

In the FIG. 2a ), the container is still completely open, wherein the lid 2 is easily placed on the container opening or on the edge 3 of the container opening. As can be clearly seen in this detail view, the receiving area 4 is formed on the circumference of the lid 2 is substantially U-shaped, wherein the receiving area is open at the bottom to receive from there the web 9 of the edge 3 of the container opening. The receiving region 4 thus has two legs 5 and 6, namely an outer leg 5 and an inner leg 6, which are connected to each other in the connecting region 7 at the foot of the U. The inner area of the lid 2 is connected to the receiving area 4 via the edge connection 22, wherein the edge connection 22 forms an opposite U with the inner leg 6 of the receiving area 4, so that the inner area 32 of the lid 2 is at the height of the upper area of the receiving area 4 is arranged. Nevertheless, the receiving area 4 in the embodiment shown forms a peripheral stacking edge, so that closed containers 1 can be stacked on top of each other, whereby mutual slipping is largely avoided by the receiving area 4.

On the outer leg 5 of the receiving portion 4, two locking lugs 12 and 13 are provided on the inside, while on the outside of a latching hook 14 is formed almost at the lower end of the outer leg 5. The locking lugs 12 and 13 and the latching hooks 14 are spaced approximately uniformly along the outer leg 5. In the immediate vicinity of the latching lug 13 and in the region between the latching lug 12 and the latching lug 13, a constriction is provided in the outer limb 5 of the U-shaped receiving area 4, then that a film hinge 15 is formed, wherein at the same time on the inside of the outer leg 5 ummittelbar adjacent to the latching lug 13, a groove 20 is formed.

The inside of the outer leg 5 opposite side of the inner leg 6 is formed as a smooth sealing surface 16, which is formed slightly inclined relative to the vertical.

Umnittelbar in the connecting region 7 of the legs 5 and 6 of the U-shaped receiving portion 4 is provided in the curvature 29 of the U-shaped receiving area space for receiving a sealing ring, not shown.

The container 1 has at the container opening on an edge which is double-walled in the lower part. In this lower portion of the edge formation 3 of the container 1, an outer web 8 is thus provided in addition to the inner web 9, which forms the double wall. The edge 3 of the container 1 thus has two sections, namely an upper first section, in which the edge 3 is formed with the web 9 and a lower second section, in which the edge 3 is double-walled with the outer web 8 and the inner Web 9 is formed. In the first, upper portion of the edge formation 3 of the container 1, two latching hooks 10 and 11 are provided on the outside of the web 9, which are formed in cross-section substantially as a nearly triangular projections.
The second, lower portion of the edge formation 3 of the container 1 has openings 25 on its upper side. At the same time, the outer web 8 forms an undercut 21 with the edge of the opening 25.

On the inside of the inner web 9 of the edge formation 3 of the container 1, a flat, smooth sealing surface 17 is formed, which corresponds to the sealing surface 16 of the receiving region 4 of the lid.

The closing process is now in the sub-images b) and c) of Fig. 2 shown. The FIG. 2 b) shows that the web 9 is inserted when closing the container 1 with the lid 2 in the U-shaped receiving portion 4, wherein the locking lug 13 first slides past the latching hook 10, while the lower end of the outer leg 5 is inserted with the latching hook 14 in the opening 25 of the double-walled portion of the edge formation 3 of the container 1.

Upon further closing of the container 1 with the lid 2, which in part c) the Fig. 2 is shown, also the locking lug 12 slides past the latching hook 10 and the latching lug 13 on the second latching hook 11. The latching lugs 12 and 13 and the latching hooks 10 and 11 are formed so that they have corresponding inclined surfaces, a mutual Allow slipping in the closing direction, while a sliding back through the positive holding is not possible. At the same time the complete closure of the lower part of the outer leg 5 is completely absorbed in the double-walled portion of the edge formation 3, wherein the latching hook 14 comes to rest under the undercut 21. Here it is clear that the lower segment 33 of the outer leg 5 is pressed when closing on the one hand by the latching hook 11 to the outside, while on the other hand by the latch hook 14, the lower segment 33 of the outer leg 5 for insertion into the opening 25 of the double-walled edge formation 3 after must be bent inside. This is made possible in particular by the formation of the film hinge 15, which makes a different movement of the lower segment 33 in accordance with the phases of placement of the lid 2 possible.

In the fully closed state can be seen that on the one hand, the locking lugs 12 and 13 form positive connections with the latching hooks 10 and 11, while the latching hook 14 with the undercut 21 also enters into a positive connection. To release the total of 3 locking element pairs, it would be necessary to move the outer leg 5 to release the locking element pairs 12 and 10 or 11 and 13 to the outside, while a solution of the locking element pair 14 and 21 would require a movement inward. Due to the inclined surface 13, which is supported on the nose 11, the locking of the locking element pair 14 and 21 is reinforced, since in the direction of Verrastungsstellung sets a leverage. Thus, however, a solution of the locking without destruction of the receiving area 4, ie the slicing or detachment of the lower segment 33 along the film hinge 15 is not possible. Only when the lower segment 33 is detached by cutting along the film hinge, the remaining Locking be solved on the locking element pair 12 and 10. This also has the advantage that the container is still usable and closable even after the initial opening, which is visible to all by the retention of the lower segment 33 in the double-walled portion of the edge formation.

In addition to the formation of the locking element pairs when sealing the container, a seal is created by the sealing surfaces 16 and 17 come into contact and in particular in clamping system by the corresponding adjustment of the dimensions of the lid 2 to the container 1 and the edge 3 of the container and In addition, sealing surfaces are pressed against each other by the locking element pairs, in particular the locking element pair 12 and 10, namely the sealing surfaces 18 and 19, as in Fig. 2c shown. In addition, in the curved portion 29 of the U-shaped receiving portion, a not-shown sealing ring can be arranged, which is pressed by the upper end of the web 9 against the connecting portion 7 of the receiving portion 4, so that an additional sealing effect is achieved.

Like from the Fig. 2c can still be seen, the positive connection in the locking element pair 13, 11 is further enhanced by the fact that a groove 20 is formed on the film hinge 15 on the inside, in which the latching hook 11 can additionally engage. The 3 and 4 show details from the cross section Fig. 2b and 2c along the respective section line DD. The 3 and 4 show how the web 9 engages between the outer leg 5 and the inner leg 6 when closing the container 1. The sectional views make it clear that both between the outer web 8 and the inner web 9 of the edge formation 3 and between the inner leg 6 and the edge terminal 22 of the cover 2 intermediate walls 23 and reinforcement walls 24 are provided, so that the second lower portion of Edge formation 3 with the double-walled edge formation at the top openings 25 which have a substantially rectangular cross-section. Accordingly, the lower portion of the outer leg 5 is provided with corresponding recesses into which the intermediate walls 23 can engage in the closed state.

As in the drawing c) the FIG. 2 is also in the 3 and 4 to see a part of the handle 27, which is also articulated in the double-walled area of the edge formation 3.

The Fig. 5 shows a perspective view of the container 1 with the lid 2. In this perspective view is particularly good to see how the handle 27 is pivotally recessed in the double-walled region of the edge 3, in particular on the outer web 8.

In addition, the partitions 23 and the reinforcement walls 24 and the openings 25 can be seen very well in this illustration. In addition, the shows Fig. 5 the design of the stack supports 26, which are arranged on the outside of the container 1 below the edge formation 3 respectively in the region of the articulation of the handle 27, wherein the operation of the stack supports 26 better in Fig. 7 becomes clear.

On the lid 2, a lid flap 28 is further provided, which enables a detachment of the lid 2 after separation of the lower segment 33 of the outer leg 5 of the receiving area 4 (as shown above).
The Fig. 6 also shows in a perspective view a part of the container 1 and a cover removed therefrom 2. Again, the openings 25 and the intermediate walls 23 between the outer web 8 and inner web 9 of the container and the reinforcing walls 24 of the lid 2 can be seen again , In addition, it can be seen in this illustration that the outer leg 5 of the receiving portion 4, is provided at the lower end of the latching hook 14, a plurality of recesses 34 so that the outer leg 5 can engage in the openings 25 and the intermediate walls 23 in the region of Recesses 34 find space.

The Fig. 7 shows in a side view and in a partial sectional view, two containers 1 and 1 'stacked one inside the other. Here, the function of the stack supports 26 and 26 'becomes clear, which sit in the stacking at the top of the web 9. This prevents jamming of the stacked buckets and ensures a defined load transfer. The side view of Fig. 7 moreover clearly shows that the latching hooks 10 and 11 are formed as circumferential strips on the edge 3 and on the web 9.

Like in the Fig. 8 in the diagrams a) and b) can be seen, however, not only the containers are stackable with each other but also the lids are stackable, such as Fig. 8 a) shows. According to the detail drawing Fig. 8b) the connecting region 7 of the receiving region 4 forms a circumferential stacking edge into which the lower end of the inner leg 6 of the overlying cover 2 'can engage. In the cross-sectional view of Fig. 8 a) and b) However, a reinforcing wall 23 is cut so that the inner leg 6 does not appear clearly. The outer leg 5 is dimensioned in its dimensions so that the lower end of the leg 5 with the latching hook 14 is slightly shorter than the lower end of the inner leg 6, so that the outer leg 5 ends above the connecting portion 7 of a cover 2 arranged underneath ,

The Fig. 9 shows in a plan view of the lid 2, the uniform division of the circumference of the lid 2 with the receiving area 4 through the reinforcing walls 24 and the recesses 34 and latching hooks 14. Although, of course, along the circumference of the lid 2, a plurality of latching hooks 14 through the recesses 34th are formed, this plurality of locking hooks 14 in the context of this application is to be understood as a locking element, since in particular all the detent hooks 14 of the circumferential undercut 21 cooperate and therefore form a pair of locking elements. Of course, of course, a pair of locking elements according to the understanding of the term, which is used here, also from a plurality of latching hooks or latching noses are formed.
