Abstract

The present application discloses a centering aid for a container having a container trough, with an access opening, a container lid and a seal. In the closed state of the container, the seal is arranged between the container trough and the container lid. The centering aid has a first centering device, which is provided on either the container lid or the container trough, and a second centering device, which is provided on the other of either the container lid or the container trough. The first and second centering devices interact in such a way as to ensure that, in the closed state of the container, the seal is in contact with the container trough and with the container lid along the entire periphery of the access opening.

First claim

The invention claimed is:

1. A container having
a container trough with an access opening,
a container lid, and
a seal which is arranged between the container trough and the container lid in the closed state of the container, whereby the seal, in the closed state of the container, is in contact with the container trough and the container lid along the entire periphery of the access opening, and a centering aid
wherein
the centering aid has a first centering device, which is provided on either the container lid or the container trough,
a second centering device which is provided on the other one of either the container lid or the container trough,
the centering devices are made from a material which has a higher modulus of elasticity than the seal,
the container trough includes a first fastening element adjacent to the first centering device, and
the container lid includes a second fastening element pivotally connected to the container lid adjacent to the second centering device, and the container lid is secured to the container trough when the second fastening element is fastened to the first fastening element, wherein
the first centering device has four planar projections which run in a lateral direction to form an angle in relation to the longitudinal axis of the container and the transverse axis of the container and wherein the second centering device has four recesses which are adjusted appropriately to accommodate and interlock corresponding planar projections.

2. A container according to claim 1 , wherein
in the closed state of the container the clearance between the first and the second centering device is smaller than the clearance between the container lid and the container trough in the event that no centering devices are provided.

3. A container according to claim 1 , wherein
the first centering device has a plurality of male centering elements and
the second centering device has a number of female centering elements.

4. A container according to claim 3 , wherein
at least one of the male centering elements is one of a parallelepiped, a cuboid, a pyramid, a truncated pyramid, a cone, a truncated cone and a partial ellipsoid in shape, and
the associated female centering element has a corresponding negative shape.

5. A container according to claim 3 , wherein
at least one male centering element and/or a female centering element has an at least partial conical area so that the clearance between the male and the female centering element at the beginning of the movement to place the container lid is greater than in the closed state of the container, wherein the associated female centering element and/or male centering element has a corresponding negative and/or positive shape.

6. A container according to claim 3 , wherein
the first centering device comprises an even number of male centering elements which are arranged in the corners of the container lid and/or in the middle of each side of the container lid.

7. A container according to claim 1 , wherein
the first and second centering devices each have at least one male and one female centering element.

8. A container according to claim 1 , wherein
the centering devices are arranged such that, in the closed state of the container, they are arranged outside the interior of the container.

9. A container according to claim 8 , wherein
the first centering device is provided directly, or via a front panel arranged on the external front faces of the container trough, on the external front faces,
the container lid includes a pair of second fastening elements which are provided on respective opposite sides of the container lid.

10. A container according to claim 1 , wherein
the projections are provided on both sides of a fastening mount on the top of two front panels which are arranged on both outer front faces of the container trough, wherein
the planar projections are more strongly beveled on their lateral front face than on their central front face so that the projections fundamentally taper in a distal direction externally, wherein
two recesses are each formed in a component which is provided between the internal front face of the container lid and the seal.

11. A container according to claim 1 , wherein
the first centering device is provided on the inside of the container lid inside the seal and the second centering device is provided on the container trough.

12. A container according to claim 1 , wherein
the centering aid has a symmetrical construction with an angle of rotation of 360°/n, whereby n is a positive integer such that the container lid is sealingly connected to the container trough in each of n rotational orientations of the container lid relative to the container trough.

13. The container according to claim 1 , wherein the centering devices are made from at least one of a rigid plastic and a metal.

14. The container according to claim 1 , wherein the first centering device includes a surface that extends in a direction that intersects an axis of the container trough.

15. The container according to claim 1 , wherein
the first centering device includes a first male centering element and a second male centering element, the first male centering element has a first surface that extends in a first direction that intersects an axis of the container trough, and the second male centering element has a second surface that extends in a second direction that intersects each of the first direction and the axis of the container trough.
