Abstract

When the lid (4) is closed by hinged action, it is sealed by deformation without extra tensioning closures on its hinged edge. By prestressing the lid, a damping action is achieved when the lid is closed. The container (1) has in its perpendicular edges narrow, inclined walls (7) which adjoin a side wall (3) and front or back wall at angles of 45 deg. The lid can have reinforcing plates around the region of the closing elements. ADVANTAGE - Reliable, tight closure of simple design.

Description

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

Such containers are widely used, whereby one of the important features of such containers consists in being hermetically sealable. To this purpose is usually around the container around, with square containers on everyone four sides, several closures arranged around the to ensure appropriate tightness of the container Afford.

The container lid is usually in a lower hinged slotted hole so that the Containers are swung open and closed on the one hand can, on the other hand in its closed position by means of tension locks can be tensioned and sealed. The handling the variety of closures is cumbersome.

The invention has for its object a gat to improve the container in that a secure tightness of the container a container can be achieved on its coulter kidney side has no closures.

This object underlying the invention will solved by the training according to claim 1.

In other words, the invention proposes that  To flap the lid deeper than its flatness kidneys. This way, when swiveling Cover a closing of the cover only by its Deformation or the resilience of you tion achievable. The lid stretched in this way points to the edge on which it is hinged, without additional latches or similar locks possible tightness.

In this way, the number of closures can ver wrestles and simplifies the handling of the container will. Furthermore, the container can in this way also be positioned so that if necessary Spannver closures arranged on its hinge side would be hard to reach. A safe and tight locking of the container lid is nevertheless possible.

The pretensioning of the cover results in damping achieved when closing the lid. This will on the one hand the seal between the lid and the container Protected top edge if the lid is not long sam managed, but struck. Farther the closing process of the lid is done by this Damping considerably quieter.

The container lid is usually on one of the longer sides of a rectangular container hinged. Accordingly, the opposite lying side the arrangement of two closures a good tightness of the container lid guarantee ren, while often only on the two narrow sides a single closure is sufficient to meet the requirements to achieve tightness. Depending on the container However, the number of closures can be dimensioned if necessary  se be reduced even further, so that a particular easy and quick handling of the container is possible.

The rigidity and tightness of the container can be improved by the usually called 90 ° trained, vertical Corners of the container replaced by two 45 ° angles with a narrow sloping wall between them record, tape. The cleaning and accessibility of the This training means that the interior of the container becomes even if further improved.

The manufacture of the container can thereby combine that the plates from which the container are formed in the area of such 45 ° edges are welded together. In the opposite Set for welding two butt to each other apt tables can with this constellation there is no need to prepare a weld.

The sloping walls between two respectively assigned 45 ° angles can also be at their top edge Form section of the hollow profile, which the Be edge of the holder is reinforced, as is the case with the other walls that is known. This will increase the rigidity of the improved upper edge of container. This creates Gaps between the profile in front of the sloping walls and the profile in front of the side or end walls be closed by intermediate pieces, so that the Profile is formed smoothly all around and Ver risk of injury in the area of such gaps be avoided.

Depending on the sheet thickness of the lid, it can be advantageous  be reinforcing plates on the lid in the area to arrange the closures. This can cause deformation of the lid can be avoided, which may lead to an Un tightness could result. At the same time here due to the material thickness of the lid be kept that the lid easily by hand can be operated.

An embodiment of the invention is based on of the drawings explained in more detail below. Here shows

Fig. 1 is a side view of a fiction, modern container with the lid closed,

Fig. 2 is a front view of the container of Fig. 1,

Fig. 3 is a side view similar to FIG. 1, but each, with the cover open

Fig. 4 is a schematic plan view of the panels forming the side walls during the manufacture of a container and

Fig. 5 is a perspective view of a corner of the upper edge of the container.

In the drawings, 1 generally denotes a container which consists of an end wall 2 , two side walls 3 and a rear wall and which has a lid 4 . The lid 4 has a hand reached 5 for its actuation and several Ver closures 6 , which take care of a tight closure of the lid 4 as latches.

The container 1 has narrow inclined walls 7 in the region of its vertically running edges, which close at 45 ° to the end wall 2 or the rear wall on the one hand and a side wall 3 on the other. An additional stiffening profile can extend outwards from the inclined walls 7 in each corner.

The cover 4 is in its lowered position with its rear edge on the upper edge of the loading container rear wall and is at the end wall 2 obliquely upwards. In this position, the lid is relaxed and not yet completely closed. It can be tensioned by pulling down on the handle 5 and then locking it with the closures 6 . In this tensioned position, the lid 4 seals airtight all around on the upper container edge.

From a hinge axis 9 , which is formed from two hinge bolts, an intermediate piece 10 extends to the cover 4 in the area of each hinge pin. Compared to the position of a hinge axis, which would allow a relaxed flat position of the lid 4 on the upper container edge, the hinge axis 9 is arranged offset downwards. As a result, the lid 4 rests with a circumferential seal on the rear upper container edge when it is in the position shown in FIGS . 1 and 2. The further closing of the lid causes deformation and particularly good sealing of the section of the seal shown.

As can be seen from FIGS. 1 and 3, the container 1 has a side-mounted catch hook 11 , which is hinged to the lid 4 and cooperates with a bracket which is fastened to a hollow profile 12 , which is on all container walls in the upper region is circumferentially formed. From Fig. 3 it can be seen that the catch hook 11 holds the lid 4 in its open position. Furthermore, the catch hook 11 has a second notch, which prevents the cover 4 from accidentally falling into its final closed position. In this way, crushing and accident hazards can be reduced ver, since this second notch in the catch hook 11 represents a safety catch.

In Fig. 4 it can be seen that the four container walls can be formed by two panels. The surrounding hollow profile 12 has gaps in the area of the 45 ° edges after the sheets have been bent. As can be seen from FIGS. 4 and 5, the two basic parts which form the four container walls can be connected by only two welds in the region of a 45 ° edge, whereby by connecting these two basic parts to one another, a correct one automatically Formation of the weld seam is favored and no further seam preparations are required.

The gaps in the hollow profile 12 in the region of the 45 ° edges which can be seen in FIG. 4 can be closed with the aid of intermediate pieces 14 , as can be seen in FIG. 5, in order to exclude the risk of injury. The hollow profile can be closed overall. However, only the areas of the gaps that can be seen in FIG. 4 can also be closed.

In contrast to the illustrated embodiment with a rigid mounting of the hinge axis 9, the hinge axis may be a formed adjustable also movable in height. 9 In this way, the cover 4 can be retightened in that the hinge axis 9 can be arranged lower, so that there is a higher clamping pressure. Such a retensioning or adjustment can take place, for example, with a diminishing effect of the circumferential seal 11 .
