Description

This invention relates to a container which is in accordance with the introductory part of patent claim 1.

Containers for the safe transport of dangerous liquid substances or dangerous substances such as dough have been known for a long time. One thing these containers have in common is that they must be leak-proof enough to prevent any leakage of the dangerous goods being transported. Secondly, they must be equipped with a closure that ensures safe closure of the tank, even with extremely heavy loads. In particular, containers of this type and their closures must withstand the loads that may occur also in the event of an accident, for example when the container falls from a certain height.

Containers of this type which are known from the state of the art include, in particular, cables or containers which have the shape of a drum and whose lids are tightly clamped with a thread, in order to obtain closure by means of a thread. To ensure closure, metal fasteners may be provided that press the lid onto the container or prevent the screw cap from unscrewing. There are also closure systems in which the lid, after being placed on the container, is suitably hemmed to create an assembly that is leak-proof. Furthermore, systems are known in which the cover or closure is connected or welded, or in which additional closing films are connected or welded.

The disadvantage that is common to all these containers, or to all these closure systems, is that they are complex and difficult to handle; This is particularly problematic given the need for largely automated handling of such facilities, including the closing process.

It is the object of the present invention to provide a container which is hermetically and securely closed, which is suitable for the transport of liquid dangerous substances or dangerous substances which are dough-like, and in addition that the production of said container and its handling are simple and efficient .

This goal is established by means of a container that has the characteristics specified in patent claim 1. Useful embodiments are the subject of dependent patent claims.

The container of the present invention, which is preferably shaped like a bucket or a drum, has a lid for closing the container, said lid having a receiving space in which, in the closed state, the lid engages the opening of the container and is retained therein. Until now, the container according to the invention was based on known containers.

Compared to the prior art, however, this invention takes a completely different approach to solving a known problem. The tank of this invention is based on such a realization, that by taking the parts that are engaged and which are completely replaceable, and by the joint action of the corresponding surfaces that close, it is possible to achieve the closing of the tank which is safe and leak-proof. The use of secure joints made of engaging elements and suitable closure surfaces ensures that separation, both handling and production, is kept simple. In this way, efficient use of the tank is ensured.

Safe joints made of interlocking elements are preferably made so that the lid of the tank can be released only if part of the lid or part of the tank is destroyed. In this way, the user has a guarantee that the first opening can be verified, since only the container that has never been opened is undamaged, while the container that has already been opened will have a damaged lid or will be damaged itself.

According to a preferred embodiment of the container, the lid receiving area and the edge of the container opening, which engages the container closure, i.e. the engaging elements which form a secure connection, and the closing surfaces are designed so that the placement of the lid, i.e. the closing of the container , performed by translational movement of the cover in relation to the container. It is particularly advantageous if the lid is simply pushed or hooked onto the container from the top. This enables the automatic closing of the container by the machine, since the processes of translational movement or pushing, or such joining to clip the parts, can easily be carried out on the machine.

According to the preferred embodiment, it is desirable to provide at least two, and preferably three or more pairs of engaging elements in the region of receiving the lid and on the lid of the opening of the container, since a greater number of pairs of engaging elements makes it possible to secure the lid at several points and thus helps to close the container securely. The term "one pair of engaging elements" does not refer here to only two engaging elements that securely engage each other, but may also refer to a large number of engaging elements which, however, due to their similar configuration and identical mode of action, they consider that they are just one pair of elements that are stuck together. This is applied so that, for example, snapping elements are simply split.

According to a preferred embodiment of the container, at least two, and preferably three or more pairs of latching elements are provided, so that at least one of these pairs of latching elements is designed differently from other pairs of latching elements , and in such a way that the movement required to release a pair of elements that snaps is different from other pairs of elements. This means that all pairs of latching elements cannot be released at once by just one movement of a part of the cover, that is, the area of acceptance of the cover, or the edge of the container opening. Conversely, the various motions required to fully release pairs of interlocking elements ensure that complex motion must be performed. It has been found particularly useful to provide at least two types of pairs of latching elements, which elements require movements in opposite directions to release the latched portion. A particularly interesting approach here, for example, is to force part of the receiving space to move both outwards and inwards to make the opening possible. This measure, in particular, in that way exceeds that measure which requires different, especially movements in opposite directions, in order to free the circumferential gripping elements on the opposite sides. What is actually meant here are the elements that engage and are more different than those listed above, and which are located close to each other, for example, one above the other.

In order to obtain different types of pairs of engaging elements that differ in different types of movement, which movements are required for release, such an engagement has the additional advantage that, in this way, a corresponding clamping action can also be created for the elements that form a secure connection, for surfaces that close and are made also in the space for receiving the lid and at the edge of the opening of the container. Even if the pressure of the surfaces to be closed is relative to any other pressure already achieved, which is obtained by the appropriate dimensioning of the cover and opening of the container, the production of different types of pairs of engaging elements, as described above, provides an additional contact pressure that can be reliably held in many stressful situations.

In addition to the closure surfaces being located separately, it is advantageous that the closure surfaces are provided which align with each other on the engaging elements and which form a secure connection, since, especially where different types of pairs of engaging elements are used which require of movement in various directions to release the grip, can perform a mutual closure that has the effect of securely blocking the elements that are engaged and which elements are pressed against each other to a certain size, thus creating surfaces for secure closure.

In accordance with the preferred embodiment, additional seals can be provided in the space for receiving the lid and/or in the space of the edge of the container opening, especially seals that are in the form of inserted or injected seals.

In order to achieve the guarantee of the first opening, as it is called, it can also be advantageous to provide an arrangement of partitions, which arrangement is predetermined in the space for receiving the cover and/or in the area of the edge of the opening of the container, in order to be able to easily separate these spaces that guarantee a secure connection that cannot be released. Here, it is particularly advantageous to ensure - in the space for accepting the cover or at the edge of the opening of the container - a predetermined arrangement of partitions, which results in that part of the space for accepting and/or the edge of the opening to be separated, that there are pair(s) ) of engaging elements that have different modes of action, since this type of pairs of engaging elements, in particular, can provide a secure connection and prevent that connection from being opened.

In accordance with the preferred embodiment, the cross-section of the lid engagement space is generally U-shaped, with the engagement area being open at the bottom to accommodate the edge of the container opening on that side. The legs of the receiving area, which has a U-shaped section, close the edge of the opening of the container and hold it firmly in such a way that it is well blocked by the gripping elements. The closing surfaces, meanwhile, are firmly pressed together against each other, thus providing a sealing effect.

Since, of course, it is possible to provide a large number of different combinations of different hooks, prongs, snap closure slots, and so forth, and suitably shaped sealing surfaces, a preferred embodiment in accordance with the present invention has in the space for acceptance, which space is U-shaped, which shape is made by means of one outer and one inner leg, two prongs or two locking hooks on the inside of the outer leg of the edge opening of the container. On its outer side, the outer leg of the receiving space, which space has the shape of the letter U, additionally has a further locking hook which is functionally connected to a cut-off part located at the edge of the container opening, said cut-off part being located in in the area of the edge of the opening of the tank, which part has double walls, and the trimmed part is located on the outer edge of the opening of the edge of the tank. By placing locking hooks or prongs on both the inside and outside of the outer leg of the receiving space, which space is U-shaped, and forming a corresponding undercut or engaging elements in the area of the edge of the container opening, two different types of pairs of elements are formed. engagements that differ in that the engaging part formed by one type of pair of engaging elements can be released by moving the outer leg outwards, while to release the engaged part, which is shaped by another type of pair of engaging elements, the outer leg must move inwards.

This simple design of the pair of engaging elements ensures, on the one hand, that the lid can be easily placed on the container by moving the lid vertically downwards. On the other hand, that triple locking system ensures that the cap fits securely on the tank. Different types of pairs of engaging elements with opposing opening movements further ensure that the lid cannot be removed without being exposed to damage.

In order to allow easy opening of the container without the use of any special tool, and to ensure that the lid is easily placed on the container, the possibility of tightening the outer leg of the receiving space, which space has the shape of the letter U, is provided so that in this space made complete joint, or joint using film, which forms the lower segment of the outer leg. One of the effects of this film joint is that the lower segment of the outer leg can make the necessary movements to pass the locking teeth or hooks and past the undercuts during container closure, that is, when the lid is placed on the container. The joint by film, that is tightening, additionally offers the possibility of separating the lower segment by simply cutting along the joint using the film with a cutting tool, such as a knife. Since it is preferable that the receiving space engaging elements for two pairs of different receiving elements are placed on the lower segment of the outer leg, only one engaging part remains after the separation of the lower segment. This last catch can be released by gently moving the outer leg of the receiving space. This only remaining catch allows for constant use and re-closing of the container after it has been opened for the first time, but does not ensure a secure closure with a guarantee of first opening. This single remaining catch also allows for continued use and resealing of the container after it has been opened for the first time, although a secure closure with a first-time opening guarantee is no longer provided.

In order to enable a uniform closure of the container, it is preferable that the gripping elements, or pairs of gripping elements, are placed circumferentially around the opening of the container and around the lid; breaking or dividing the engaging element by recesses, protrusions, and so on, may result in the creation of a correspondingly greater number of engaging elements, however, as defined in the present invention, the intent is to uniformly close and treat as a single member for gripping or with two gripping members connecting one pair of gripping elements.

Thanks to the measures described above, standard materials can be used for a container that is in accordance with the present invention, without having to take special measures. Plastics based on polyolefins, especially polyethylene and polypropylene, are preferred. Preferably, the sealing aid that is additionally used does not need to fulfill any special requirements relating to the choice of material, although, depending on the application in question, there may be special requirements relating to the choice of material. The dimensioning of the components itself, for example, the wall thickness, must be adjusted to adapt to the application, to withstand the necessary forces also in case of special loads caused by, for example, accidents.

Further advantages, characteristics and properties of the invention will become clear from the detailed description of the embodiment, which follows, and from the accompanying drawings. Drawings are purely schematic.

Figure 1 shows a side view, in partial section, of a closed container 1 according to the present invention, that is, of a container that is closed with its lid 2. In the embodiment shown, the container 1 has the shape of a cable on which it works for easier carrying, attached handle 27 that can be rotated.

As can be seen in the partial section of one part of figure 1, the container 1 has a bottom 30 which is slightly arched inwards and which bottom has a supporting foot 31 on its outer edge; in this way, there is a small gap between the bottom 30 and the surface on which the clear stands. Container 1 furthermore has a slightly conical, although mostly cylindrical, external shape, so that empty containers can be placed one inside the other.

Figures 2a to 2c show details of the part that has been cut, with the receiving space 4 and the edge 3 of the container opening, in different degrees of closure of the container 1.

In Figure 2a, the container is still fully open; the lid rests lightly on the opening of the container, that is, on the edge of the 3 opening of the container. As can be clearly seen in this detailed view, the receiving space 4 on the rim of the lid 2 is generally U-shaped, with the receiving hole open at the bottom so that the element 9 of the rim 3 receives the opening of the container on that side. The receiving space 4 thus has two legs 5 and 6, namely one outer leg 5 and one inner leg 6, which are connected to each other in the connection area 7 at the bottom of the U-profile. The inner part of the lid 2 is connected via the connecting edge 22 with the receiving space 4; the connecting edge 22 has the shape of an inverted letter U with the inner leg 6 of the receiving space 4, so that the inner part 32 of the lid 2 is located at the level of the upper part of the receiving space 4. The receiving space 4, in the embodiment shown, forms a circumferential raised edge , so closed containers can be stacked one above the other. Any movement of one towards the other is largely prevented by the space to accommodate 4.

On the inside of the outer leg 5 of the receiving space 4, there are two teeth 12 and 13, while on the outside of the outer leg, almost at its bottom, there is a locking hook 14. The teeth 12 and 13 and the locking hook 14 are located at approximately equal intervals along the outer leg 5. In the immediate vicinity of the tooth 13, in the area between the tooth 12 and the tooth 13, one structure is provided in the outer leg 5 of the receiving space 4 which has U shape, so that the built-in joint 15 or the joint formed by the film 15 is made; at the same time, on the inner side of the outer leg 15, right next to the tooth 13, a groove 20 is made.

The side of the inner leg 6 that is opposite the inner side of the outer leg 5 is designed as a smooth sealing surface; that sealing surface is slightly inclined relative to the vertical.

Directly in the area 7 connecting the legs 5 and 6 of the receiving space having a U shape, in the curved part 29 of the receiving space having a U shape, a space is provided for placing a seal which is not shown.

At its opening, container 1 has an edge that has double walls in the lower part. In the lower part of the edge 3 of the opening of the tank 1, in addition to the inner element 9, there is also an outer element 8 that forms a double wall. The edge 3 of the opening of the container 1 is thus made of two sections, namely one upper, first section in which the edge 3 of the opening includes the element 9 and has one wall, and one lower, second section in which the edge 3 of the opening includes the outer element 8 and the inner element 9, thus forming two walls. In the first, upper section of the edge 3 of the opening of the container 1, on the outer side of the element 9, two blocking hooks 10 and 11 are placed, which in cross-section are shaped mainly as triangular protrusions. The second, lower section of the edge 3 of the container opening 1 has openings 25 at the top. At the same time, the outer element 8 with the edge of the opening 25 forms a cut part 21.

On the inner side of the inner element 9 of the edge 3 of the opening of the tank 1, a smooth flat sealing surface 17 is formed, which fits against the closing surface 16 of the space for receiving the lid 4.

The closing procedure is shown in Figures 2b and 2c. Figure 2b shows that when closing the container 1 with the lid 2, the element 9 is inserted into the receiving space 4 which has the shape of the letter U, with the tooth 13 which first slides over the blocking hook 10, while the lower end of the outer leg 5 with the blocking hook 14 leads into the opening 25 of the section with two walls of the cover 3 of the tank opening 1.

As the container 1 is further closed with the cover 2, as shown in Figure 2c, the tooth 12 also slides over the locking hook 10 and the tooth 13 over the second locking hook 11. The teeth 12 and 13 and the locking hooks 10 and 11 are designed to have complementary inclined surfaces that allow the prongs to slide over the hip in the closing direction, where they are prevented, by means of a safe locking grip, from sliding back again. At the same time, on the entire closure, the lower part of the outer leg 5 is completely adjusted into the double-walled section of the edge opening 3, the blocking hook 14 comes to rest position comes under the trimmed part 21. Here it becomes clear that after closing the lower segment 33 of the outer the legs 5 are pressed from one side outwards by means of the blocking hook 11, while, on the other hand, the lower segment 33 of the outer leg 5 must be bent inwards, by means of the blocking hook 14, in order to be inserted into the opening 25 of the edge opening 3 which it has double walls. This seems possible especially also due to the configuration of the joint 15 which is made as a film, and which enables different movements of the lower segment 33 depending on the state of closure with respect to the cover 2.

In the fully closed state, it is clear that firstly, the prongs 12 and 13 form secure connections with the blocking hooks 10 and 11, while further, the blocking hook 14 forms a secure connection with the cut part 21. To release all three pairs of elements which are engaged, it would be necessary to move the outer leg 5 outwards to release the pairs of engaging elements 12 and 10 and 11 and 13, while an inward movement would be necessary to release the pair of engaging elements 14 and 21. As a consequence of the inclined surface 13, which rests on the tooth 11, the engaging effect of the pair of engaging elements 14 and 21 is further enhanced, since the lever effect acts in the direction of the engaging position. Therefore, it is not possible to release the gripping mechanism without destroying the receiving region 4, that is without cutting or separating the lower segment 33 along the joint 15 which is made as a film. Only if the lower segment 33 were to be separated by cutting along the joint which is made as a film, the grip, which still remains, can be released with the help of the pair of grip elements 12 and 10. It is an additional advantage that after the container has been the first time open, which is visible to everyone due to the lower segment 33 remaining in the section of the edge of the double-wall opening, the container is still suitable for continuous use and can be closed again.

In addition to the formation of a pair of engaging elements, a seal is created after the container is closed due to the closing surfaces 16 and 17 coming into contact, in particular, because they are pressed together due to the appropriate adaptation of the dimensions of the cover 2 to the dimensions of the container 1 or to the edge of the opening 3 of the container, and because corresponding configurations of the gripping mechanism between the receiving space 4 and the cover 3. In addition, the pairs of gripping elements, especially the pair of gripping elements 12 and 10, are also pressed together by the closing surfaces, in this case the closing surfaces 18 and 19, as is shown in Figure 2c. In the curvature zone 29 of the receiving space, which has the shape of the letter U, an additional seal, not shown, can be included, which is pressed by the upper end of the element 9 towards the connection area 7 of the receiving space 4, thereby producing an additional sealing effect.

As is also clear from Fig. 2c, the secure connection created by the pair of engaging elements 13, 14 is further reinforced by the groove 20 which is provided on the inner side of the joint 15, which joint is made as a film, and in which the groove can additionally engage locking hook 11.

Figures 3 and 4 show, in cross-section, the details of figures 2d and 2c, in each case along the line D - D. Figures 3 and 4 show how the element 9 engages between the outer leg 5 and the inner leg 6 after the container 1 is closed. The cross-sectional view explains that between the outer element 8 and the inner element 9 of the edge 3 of the opening and between the inner foot 6 and the edge of the opening the connection 22 of the cover 2, partitions 23 and reinforcement walls 24 are placed, so that the second, lower section of the double wall of the opening edge 3 has openings 25 at the top which are generally rectangular in cross-section. The lower space of the outer leg 5 is also provided with a complementary recess into which the partition 23 can be engaged, when the container and lid are in the closed state.

Figures 3 and 4, as well as figure 2c, show part of the lever 27, which is also connected via a hinge to the double-walled region in the area of the edge 3 of the opening.

Figure 5 shows a perspective view of the container 1 with a cover 2, which cover is located on the container. This perspective view shows particularly well the manner in which the lever 27 is hinged, so that it can be rotated, in the region of the edge 3 of the opening of the double-walled region, especially to the outer element 8.

Partitions 23, reinforcement walls 24 and openings 25 can also be seen very clearly in this projection. Fig. 5 also shows the configuration of the support parts 26 when stacking the containers one inside the other, which support parts are located on the outside of the container 1, below the edge 3 of the opening, near the place where the hinge for turning the handle 27 is. Fig. 7 shows more clearly how they work supporting parts when stacking containers one inside the other. The cover 2 also has a pulling means 28 attached thereto, by means of which the cover can be removed after the lower segment 33 of the outer leg 5 in the receiving space 4 has been separated (as shown above).

Figure 6 shows in the same way a perspective view of a part of the container 1 and of the cover 2 which has been removed from the container. From this projection, it is additionally visible that the outer leg 5 of the receiving space 4, on which the lower end of that leg is placed the blocking hook 14, has a large number of recesses 34, so that the outer leg 5 can engage the openings 25, and the partitions 23 find their place in the space of recess 34.

Fig. 7 shows, in side view, which view has a partially cut away part, two containers 1 and 1 ́ which are stacked one inside the other. Here it becomes clear how the supporting parts 26 and 26 work, which, when the containers are placed one inside the other, rest on the upper edge of the element 9. This prevents the containers, when stacked one inside the other, from jamming, and this ensures a certain load distribution. The side view, which is shown in figure 7, also clearly shows that the blocking hooks 10 and 11 are made as peripheral tips on the edge 3 of the opening, that is on the element 9.

As is evident from Figures 8a and 8b, not only are the containers stackable, but also the lids are stackable, as shown in Figure 8a. As shown in the detailed drawing in Fig. 8b, the connecting space 7 of the receiving space 4 forms a peripheral edge for stacking the covers in which the lower end of the inner leg 6 of the cover 2 ́, which is placed from the upper side, can be caught. In the cross-sectional view shown in Figures 8a and 8b, however, the reinforcement wall 23 prevents the inner foot 6 from being clearly visible. The outer leg 5 is dimensioned so that the lower end of the leg 5 with the locking hook 14 is slightly shorter than the lower end of the inner leg 6, so that the outer leg 5 ends above the connection area 7 of the cover 2 which is placed on the lower side.

Fig. 9 shows, in a top view of the lid, a uniform distribution of the circumference of the lid 2 with a receiving space 4, which is reinforced with walls 24 and which has recesses 34 and locking hooks 14. Although, of course, a large number of hooks for blocking 14 around the circumference with the help of notches 34, this large number of blocking hooks 14 should be understood, for the purposes of this application, as one element to accept, since all blocking hooks 14 with the cut part 21, which is on the periphery, and therefore one pair of gripping elements. By analogy, of course, and in the meaning of the term as used herein, a pair of engaging elements may also be made of a large number of different hooks and prongs.
