Description

The The invention relates to a container consisting of a bucket and a Lid, wherein the lid is latched with a bucket edge and with the lid closed, close the bucket with the bucket having a pail base disposed on a lid surface within a lid edge can be placed.

A comparable container or vessel, which is suitable for the stacking by placing several containers on top of each other, is for example from DE 90 15 918 U1 known. This is a bucket is described, which has an outer fastening edge, the free edge has approximately against the free edge of the vessel and latching with an associated lid is connected, the edge of a cross-sectionally approximately U-shaped, opposite the edge of the vessel has open profile whose interior Leg forms a rim surrounding the edge of the vessel from the outside and the outer leg terminates in a locking edge engaging behind the outer fastening edge of the vessel, wherein the support edge protrudes to the outer fastening edge of the vessel and is seated with its front edge fed on this fastening edge.

That from the DE 90 15 918 U1 known vessel transmits, for example, from a further, patch vessel applied to the lid forces on the support edge on the mounting edge of the vessel and thus on the vessel wall. A consistent and safe transfer of force along the vessel wall, which supports the stacking of several vessels on top of each other, is the result.

Furthermore, from the DE 43 06 982 C2 It is known that when stacking a plurality of buckets closed with lids, the mechanical load on the container is particularly high when, for example due to a small footprint of an attached bucket, the point of force application moves into the middle of the lid of the underlying container. In such a case, the risk of dislodging the lid is particularly pronounced and can lead to the tipping over of a bundle stack associated with the loss of the contents of the container.

At the Transport of containers, their storage and the everyday Handling of containers, it is often beneficial or necessary reach large stack heights of containers. simultaneously Safe stacking is an important prerequisite for and to avoid property damage. For big stack heights however, filled containers often show up Failure of sealed containers by disengagement or kinking or bumps of the vessel walls.

The Invention therefore has the task of the stackability of containers continue to improve and thus an even more economical use of containers.

The The object is achieved by providing a container is made, which consists of a bucket and a lid, the lid can be locked with a bucket edge and with the lid on the Bucket closes, with the bucket having a bucket bottom, the on a lid surface of an adjacent container can be placed within a lid edge, and wherein the lid surface and / or the pail bottom increased and / or lower bearing surface sections have or have.

Thereby that the lid surface and / or the pail bottom increased and / or lower lying bearing surface sections or, for example, is an inventive Eimerboden when stacked on a container with conventional or inventive lid first only on the lower lying bearing surface sections on. This makes it possible to control the flow of power that comes from the Weight load of the empty or filled, put on Container originates, deliberately in areas of the container cross-section to steer or control, in principle, over have a higher load capacity.

Consequently can other areas of the container cross-section, the risk of failure are relieved, and it comes only at a higher Weight load to a failure of the container by kinking, Bumps or tearing of the container walls or disengagement of the lid. Overall, the inventive Container higher loadable and thus allows larger Stack heights or at lower stack heights a weight-optimized and material-saving design of the container. Becomes a bucket with a conventional bucket bottom for stacking on a container with an inventive Cover attached, it also comes first to the elevated Support surface portions of the lid to a support and the power flow takes place via these contact surface sections. Depending on the degree of filling of the container is the pail bottom possibly despite raised respectively lower lying bearing surface sections in a certain Bend or bulge the circumference. Such a deflection or bulge may cause that the pail floor then also in other places, such as the bottom of the bucket, resting on the lid underneath. In such a case, the primary power transmission takes place however, still above the elevated or lower lying bearing surface sections.

Under Lid surface according to the invention each Cover surface understood regardless of its topography, which lies within the lid edge and formed according to the invention is (for example, to the center of the lid running ribs).

has the container has an oval cross-section, this has the advantage that characterized mainly by the bucket walls Interior of the container barely dirt-prone edges or corners and thus is particularly easy to clean. This supports thus the reusability of the container in a special way.

If on the lid surface, the elevated bearing surface sections in the range of maximum curvatures of the oval cross-section are formed, then this has the advantage that the power flow over Areas of the container cross section takes place, anyway due to the oval basic shape over a higher rigidity feature. The areas of lesser curvatures of a Bundles are generally more unstable and therefore particularly stackable endangered by buckling or bumps. The areas of lesser Curvature is over by the targeted power flow control the bearing surface sections in the areas of maximum Curvatures thus relieved. According to the invention under bearing surface sections primarily surface sections To understand the surface of the container, the edition serve. In addition, under area sections also arcuate surface sections for support understood, if necessary, when stacking empty Containers immediately in the area of maximum curvature result.

are at the bottom of the bucket the lower lying bearing surface sections in the range of maximum curvatures of the oval cross-section trained, so this has the same advantage as in the case of increased Support surface sections on the oval cover. The power flow takes place over areas of the container cross-section, which anyway due to the oval basic shape over a higher Have stiffness and a discharge of the container occurs one.

has the container on a polygonal cross-section, so can transported goods better with such a container become. Such containers use in special applications the available space due to the nature the goods to be transported better. Under polygonal cross-section are three, four and more polygons to understand the corners while corners in the narrower sense, that is, corners the one edge have, as well as rounded corners can be.

If on the cover surface of a polygonal container cross-section the raised bearing surface sections in the area the corners of the container are formed, then the same effect as in a container with oval cross section, the bearing surface sections achieved in the areas of maximum curvature achieved. The weight of one on a polygonal lid attached container is primarily removed over the support surface sections, So in the area of the corners of the polygonal container. In this area, the containers are due to the corners, analogous to the containers with oval cross-section, basically more stable or stiffer. A relief of the rest Areas are the result.

are the lower lying bearing surface sections on the bottom of the bucket formed in the region of the corners of the polygonal cross-section, so again this has the same advantage as in the case of increased Attachment of the bearing surface sections to a cover a container with polygonal cross-section.

If a transition from the elevated contact surface sections to the remaining lid surface and / or a transition from the lower lying bearing surface sections to remaining pail bottom stepped, bevelled or rounded is formed, then the pail bottom is in the range of a step additionally stabilized and defined above In addition, the bearing surface portion as a closed Paragraph. If desired, this can help to ensure that it also with completely filled containers too no sag of the pail bottom in the area between the bearing surface sections comes and thus the power flow strictly on the bearing surface sections remains limited. In the event that the transition folded, this leads to a clean, and visually appealing lines. Will the transition Rounded out, this is the least dirt-prone solution. In the folded or rounded case, the transition from the elevated contact surface sections to remaining lid surface and / or the transition from the lower lying bearing surface sections to Remaining bucket ground targeted continuously designed.

is the container made of low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP) or another plastic, then the container receives a number of advantageous properties, such as a great resistance through high toughness and elongation at break values and a very low water absorption.

In the following description of the figures embodiments of the invention are shown. All features of the invention are shown schematically and not to scale. The invention is not limited to the above specified embodiments. Rather, a number of variants is conceivable, which makes use of the features of the invention even with fundamentally different type of execution. The figures show in detail:

1 a lid according to the invention in a perspective view;

2 a cross section through a lid according to the invention;

3 a perspective view of a bucket according to the invention; and

4 a side view of the bucket according to the invention which is placed on a cross-section shown in accordance with the invention lid.

In the 1 is with 10 an oval lid of the container according to the invention. In the outer area of the lid 10 is a lid edge 12 formed, which has a lid surface 14 encloses. The lid edge 12 is with one in the 1 Bucket not shown latched and thus closes lid 10 and buckets to a container. According to the invention, the cover surface 14 a special shape. It has in the areas of maximum curvature 16 each bearing surface sections 17 , with respect to the remaining lid surface 14 raised on the lid 10 are attached.

In the 2 is the lid according to the invention 10 from the 1 shown in a cross section. As a result, the profile of the lid surface 14 particularly clearly visible. In particular, the two bearing surface sections 17 in the areas of maximum curvature 16 as well as a center area section parallel thereto 18 shown. Between the bearing surface sections 17 and the mid-surface portion 18 close each two inclined surfaces 19 on, with bearing surface sections 17 , Mid-surface section 18 and inclined surfaces 19 together the lid surface 14 form.

In the 3 is in a perspective view an oval bucket 30 a container according to the invention shown. The bucket 30 has a specially shaped pail bottom 34 , where in the areas of maximum curvature 16 the oval bucket cross section low lying bearing surface sections 37 are formed, to which each inclined surfaces 39 connect that in a raised mid-surface section 38 end up. Supporting surface portions 37 , Mid-surface section 38 and inclined surfaces 39 make up the bucket floor together 34 of the bucket 30 and make sure that the bucket 30 when resting on a lid exclusively or mainly over the low-lying bearing surfaces 37 supported.

In the 4 is a bucket according to the invention 30 shown on a cross-section illustrated erfindungsemäßen cover 10 is attached. The bearing surface sections 37 of the bucket 30 lie on the entire surface of the bearing surface sections 17 of the lid 10 on. This will determine the weight of the empty or filled bucket 30 exclusively over the areas of maximum curvature 16 transfer, whereby areas of lesser curvature are relieved. This relief causes a failure of the container in total only at higher loads, ie z. B. occurs at larger stack heights. The different degrees of filling of the container could, depending on the flexibility of the bucket material, to a certain bulge of the pail bottom 34 lead, whereby in the stacked state, the middle surface sections 18 and 38 would be less spaced apart.

The invention relates to a container consisting of a bucket 30 and a lid 10 , where the lid 10 with a bucket edge 12 can be locked and with the lid on 10 The bucket 30 closes, taking the bucket 30 a bucket floor 34 which is on a lid surface 14 within a lid edge 12 can be placed. Because of the lid surface 14 and / or the bucket floor 34 raised and / or lower bearing surface sections 17 . 37 In the stacking of such containers, a relief of regions of the container which are at risk of failure can be achieved, so that the container according to the invention as a whole fails only at higher loads. As a result, for example, the stacking height of such containers can be increased while maintaining a safety limit, which can be advantageous for example when storing them.
