The container (10) comprises a cover (14) that is pivotally mounted at a container portion (12). A circumferential seal portion is provided for sealing the container portion and cover. The seal portion closed with the cover is pressed against a sealing surface. A joining portion on a container rear wall is movably and vertically supported between the cover and container portion. A pulling element is attached to the rear wall, for pulling the cover downwardly to a lowered position in which the seal portion is pressed together.

Description

The invention relates to a container, according to the preamble of claim 1.

Containers with a container body and a hinged lid attached have long been known. For example, the famous Zarges boxes are built on this principle. An attached to the container rear wall hinge carries a lid pivotally. By means of closures attached to the container front wall, the lid is closable, with a circumferential seal allowing a seal between the container lid and the container body.

Such containers are very widespread and have many advantages. They have been used for more than 50 years, as evidenced by the DE 1 780 559 A1 or the DE 1 925 474 A1 results.

In order to improve the durability - especially with regard to possible deformations during rough treatment - even further, attempts have been made to use additional beads or reinforced profiles for such transport containers, and it has also been proposed to increase the wall thickness. However, this proposal leads to the disadvantage of a higher weight and higher material costs for the production of the box.

It is an object of the present invention to provide a container according to the preamble of claim 1, which is still improved in terms of durability, without significant disadvantages such as a higher weight of the transport container would arise.

This object is achieved by claim 1. Advantageous developments emerge from the subclaims.

In the case of a container according to the invention, it is provided to pull the lid onto the container body in a lowered position via a special pulling element on the container rear wall side. In principle similar tension elements are in the form of toggle fasteners, as for example from one of the above-mentioned patent publications can be seen, and how they are used regularly container front wall side.

Surprisingly, this results in a long-term durability, and it is in this respect an extension of life possible, in particular also, as regards the tightness of the container. By the tension element according to the invention, which can be mounted in the same manner on the container rear wall as well as on the container front wall, the seal is pressed around with everywhere the same vertical movement and the same force and compressed, which significantly benefits their life. In particular, it is not overstressed or sheared off by unilateral loading or oblique loading.

This is particularly true for extreme temperature fluctuations, because it is known that the thermal expansion coefficients of elastomers are different from those of metal such as aluminum. By according to the invention presses the sealing surface in the vertical direction and everywhere with the same force on the seal, the introduced sealing force can be distributed optimally around. In this respect, it is particularly advantageous if four closures are mounted on the longitudinal sides of the container relatively close to the corner, since then the distances between the individual closures - viewed over the course of the seal - are substantially equal.

It is understood that a rear tension element only makes sense if the joint between the lid and the container body has vertical play. This clearance should correspond at least to the desired pressing path of the seal and may be for example 1 to 7 mm, for example 2 to 3 mm. Preferably, the play consists only in the vertical direction, while the horizontal play of the joint is limited to much lower values, such as 0.1 or 0.3 mm.

In an advantageous embodiment, the closure body are each attached to the container bodies, and the closure hooks each on the lid. This per se proven arrangement of closures on the front of the container can be inventively also take over for the container rear wall, in a particularly advantageous embodiment, the container joint can also be integrated into the closures equal. For this purpose, a joint extension is expediently formed on the closure hook, and the closure joint which is anyway required for the closure then also becomes part of the container joint.

There can be realized by realizing a long hole drilling a game in the desired manner readily, which bore then receives the pivot pin of the closure.

The realization of the articular process is the realization of the closure, moreover, as toggle lock in the way. In a manner known per se, the closure hook thus has a hook projection which can be engaged by a bracket of the closure. The bracket is mounted in a manner also known per se pivoting on the closure lever of the closure, which in turn is mounted on the closure joint on the closure bearing plate, which is fixed container container fixed. By pivoting the bracket into the position overlapping the hook projection, tension can be exerted via the bracket when the locking lever pivots against the locking bearing plate, which pulls the cover downwards over the locking hook into the lowered position, so that the seal is compressed. By this interaction, the tension element is formed.

The seal is preferably attached in a conventional manner to the inner corner of the lid, for example, foamed, and has vertically down to a container body fixed sealing surface. The sealing surface is preferably formed on a circumferential profile of the container body at its upper edge.

By pulling through the closure as an exemplary embodiment of the tension element according to the invention on the container rear wall, as well as by the train on the front side of the container via the closures typically there applied a contact pressure for the seal, which presses them against the sealing surface.

It is understood that instead, in the same way, the seal can be mounted on or in an upper end profile of the container body and then pressed against a sealing surface which is provided on the lid.

According to the invention, it is particularly favorable that a standard transport container, which is equipped with the features according to the invention, can not only be certified according to IP 65, but also remains permanently tight. Surprisingly, the fact that uniform sealing force and only vertical sealing force is exerted on the seal, achieve a much better permanent seal with the same seal and the same sealing surface.

In an advantageous embodiment, a spring is provided which pushes the lid upwards, in the upper position. This can be configured in any suitable manner, but is also preferably also integrated into the closure, which is also provided analogously in addition to the container rear wall. This spring also prevents a grinding movement of the lid when closing the container with the seal against the sealing surface; only when pressing the rear closures of the container, the seal there accordingly in abutment with the sealing surface.

In a further embodiment of the invention, it is provided to provide a known per se joint between the lid and the container body, which allows in addition to the pivoting movement a stroke in the vertical direction. This joint is preferably provided with an additional spring, which pushes the lid - as explained above - upwards. In this embodiment, commercial closures are provided, suitably adjacent to the corners of the container, which then serve as a tension element and cause the desired pressing of the seal to the sealing surface.

In a particularly advantageous embodiment of the invention, it is intended to use as closures for the container rear toggle locks. Such toggle fasteners then have the property that they snap open by themselves if they are not released before the container is opened. Damage caused by careless operation of the transport container is thus excluded.

In a further advantageous embodiment may also be provided by appropriate dimensioning of the spring, that this also serves in a double function as a pivoting brake for the lid. For this purpose, the articular process of the closure hook is slightly thickened on the outside. When the cover is pivoted, it presses against the spring and the spring force is increased just before the cover assumes its open end position.

Further advantages, details and features will become apparent from the following description of an embodiment of the invention with reference to the drawing.

Out Fig. 1 a container 10 can be seen, which has a container body 12 and a container lid 14. In the illustrated embodiment, the container is stackable, for which he has a total of four stacking corners 18 on the lid. The container body is reinforced with circumferential beads 20 and has on the front sides carrying handles 22. At the not visible here long side, the container front wall, two commercial knee lever locks are provided, with which the container is closed.

The container lid 14 is pivotally mounted on the container body 12 via a hinge 24. According to the invention for this purpose two special closures 26 and 28 are provided, which are similar to the outer appearance substantially not shown and commercially available toggle fasteners, which are provided on the container front wall. The closures 26 and 28 are in a conventional manner toggle locks and the pivot pin 30 for the storage of the locking lever 32 on the closure plate 34 also serves as a joint 24. For this purpose, the locking hook 38 which is attached to the lid 14, extended slightly downwards and engages in a manner apparent from the other figures, the pivot pin 30th

In a manner known per se, a bracket 40 of the locking lever 32 further surrounds a hook projection 42 of the locking hook 38.

When opening the lid 14 - after unlocking the front fasteners, not shown - now the locking hook 38 moves slightly to the rear, beyond the dead center of the toggle closure, and the closures 26 and 28 snap on.

The front closures, but also the closures 26 and 28, but apart from the configuration of the closure hook 38, may be formed in any suitable manner as toggle closures, for example according to the DE 20 2007 010 029 U1 , to which reference is made in full content.

Out Fig. 2 is the arrangement of the invention hinge and tension element schematically, but seen in perspective and broken.

The tension member is made in this embodiment by the combination of the bracket 40 with the locking lever 32 and the closure plate 34 when the bracket 40 engages behind the hook projection 42. The locking hook 38 forms with the Fig. 2 seen joint extension 50 together the joint flap 52. This is firmly attached to the lid 14 and also on a closing profile 54. In the effective position of the tension element, ie, when the bracket 50 pulls the hinge tab 52 down, a seal 56 is pressed from above against a sealing surface 58 and pressed together, so that the seal is made.

The embodiment of the articular process 50 is made Fig. 2 also visible. There, the pivot pin 30 of the locking hook 32 is guided in a slot hole 60. The extension direction of the slot is vertical and allows the vertical relative movement between the lid 56 and the container body 12th

From below, a spring designed, for example, as a leaf spring 62 presses against the joint flap 52, namely against the joint extension 50. As a result, the cover 14 is raised relative to the container body 12, so that the seal 56 does not bear against the sealing surface 58 without the action of the tension element 48, but is lifted from this.

The sealing surface 58 is formed on an upper end profile 66 of the container body 12. In addition to the sealing surface, the profile 66 has a nose 68, which has a lower height than the seal 56 in the in Fig. 2 has shown, expanded state.

If the pulling element 48 on the hook projection 42 pulls the locking hook 38 downwards over the bracket 40 and the seal 56 is thereby pressed against the sealing surface 58, this only takes place until the nose 68 abuts against the inside of the cover 14. This results in a squeezing the seal 56 reliably prevented.

Out Fig. 3 It can be seen in detail how, in this lowered position, in which the closure is closed, the individual parts according to the invention lie to each other. Like reference numerals designate like parts here as well as in the other figures. It can be seen that the bracket 40 assumes an over-center position in this state, so that it is closer to the container body 12 than the hinge 24 having the pivot pin 30.

In this state, the spring 62 is compressed so that its leaf spring-like portion 70 is pressed down, and the pivot pin 30 extends at the bottom through the slot 60.

In contrast, this is off Fig. 4 the upper position can be seen, in which the closure 26 is open. The bracket 40 is disengaged from the locking hook 38. By the action of the portion 70 of the spring 62, the locking hook 38 is pushed upward, so that the seal 56 is relieved and just above the sealing surface 58 floats. In this state, the lid 14 can be opened at will, after he rests there freely. The pivot pin 30 here occupies the uppermost position in the slot 60.

The opened state is off Fig. 5 seen. There, the lid 14 extends at an angle of slightly more than 90 ° to the top of the container body 12. The spring 62 is practically relaxed, however, the portion 70 is slightly pushed down after the articular process 50 at the then the section 70 facing point has a convex bulge to the outside. This causes a certain counterforce when completely opening the lid 14 relative to the container body 12, and thus forms in some way a soft stop when opening the container 10th
