Definitions

  • the invention relates to a cool box for keeping liquid-filled, in particular cylindrical containers cool, consisting of a pot-shaped lower part, in which at least one cooling element arranged on the side walls of the containers is interchangeably inserted, and of a cover which can be placed thereon, between the and the bottom of the lower part the cooling element is fixed and is recessed in the area of the container projecting above the top edge of the cool box.
  • the pot-shaped lower part has a circular cross section and a circular lid.
  • the lid has a separate circular recess of the same size for each circular cylindrical container that can be set and cooled in the cool box. These recesses are arranged in a concentric circle around the central perpendicular of the pot-shaped lower part.
  • a single cooling element is placed centrally in the cool box in such a way that it extends from the bottom of the lower part which extends to the underside of the lid and the set containers surround the cooling element.
  • the side surfaces of the cooling element have indentations along their entire height, in such a way that the cylindrical containers nestle against the indentations with their outer walls.
  • a disadvantage of these known coolers is that the containers arranged in a concentric circle and at a distance from one another take up a lot of space and a lot of free space is left by the warm ambient air passing by the containers, which heats the containers quickly.
  • Another disadvantage is that the recess provided separately for each container is only suitable for the arrangement of cylindrical containers with almost the same diameter of the bottom surface, since containers that are too large do not fit into the recesses and containers with a smaller diameter do not come into contact with the centrally arranged cooling element occur, resulting in an insufficient cooling effect.
  • Another known cool box differs from the aforementioned known cool box mainly in that, instead of the central cooling element, the lid is designed as a cooling element in that the lid is hollow and is filled with a cooling liquid.
  • This cover represents the only cooling element of this cool box and cools the cylindrical containers introduced into the cool box only in the narrow-area contact area between the cover and the outer wall of the container.
  • the object of the present invention is to create a cool box which does not have the disadvantages of the prior art described.
  • the lower part has the shape of a prism with rectangular side walls, which encloses the container which can be brought into a hexagonal closest arrangement as a whole, that a plate-shaped cooling element is arranged on the inside of each side wall of the lower part is, which are profiled at the corners of the prismatic inner part, for the purpose of mutual support, that their movement into the interior of the lower part is not possible, and that the lid has a single central recess, the edge portions of which run parallel to the side walls.
  • containers of different sizes and numbers can be accommodated within the only central recess in the lid in a hexagonally close arrangement, taking into account the space predetermined by the interior, i.e. one container each is located in a wedge-shaped trough which is formed by two containers standing next to one another. This leaves a minimum of empty space between the containers.
  • a plate-shaped cooling element Arranged on the inside of each side surface is a plate-shaped cooling element, which comes into direct contact with each nearest container to be cooled and cools both the containers located directly on the cooling element and the containers arranged in the rear rows in a hexagonal arrangement.
  • the advantage of this solution is, in particular, that a high packing density of the containers to be cooled is achieved. In this way, an optimal ratio of cold room to coolant room is achieved for a given cool box footprint. Furthermore, the contact of the containers ensures an even, slow due to the minimal convection area Heating of all containers.
  • the cool box preferably has the base of an equilateral triangle, in which the plate-shaped cooling elements are supported against one another, so that they cannot fall into the interior of the lower part.
  • the cooling elements are dimensioned the same, so that an incorrect insertion of the cooling elements (confused with different types of cooling elements) in the lower part of the cool box is avoided.
  • the inner sides of the cooling elements can have fillets against which the outer walls of the containers of the first row to be cooled nestle, as a result of which there is a larger contact area between the goods to be cooled and the cooling element in comparison to flat cooling elements.
  • plate-shaped insulating elements are preferably provided between the cooling elements and the inner sides of the side walls of the lower part.
  • the 1 shows a cool box 1 consisting of a prismatic, pot-shaped lower part 3 and a cover 5.
  • the lower part 3 has the base of an equilateral triangle and side surfaces 6 which are perpendicular to it.
  • spacers 10 which are fastened to the inner sides of the side surfaces 6 and keep the cooling elements 4 filled with liquid at a distance from the side surfaces 6 of the lower part 3.
  • thermally insulating air gap 11 In the space between the cooling elements 4 and the inside of the side surfaces 6 there is a thermally insulating air gap 11, which, however, can also be filled with insulating material.
  • the cooling elements 4 there are three circular-cylindrical containers 2 in the hexagonally closest arrangement, ie a container is located in the wedge-shaped depression which is formed by the other two circular cylindrical containers. With this arrangement, a maximum contact area is achieved between the containers 2 with one another and between the containers 2 and the cooling elements 4.
  • the base of the cover 5 has the same shape and the same dimensions as the base of the lower part 3.
  • the cover 5 has a central recess 7, the edges 8 of which run parallel to the outer edges 6 'of the cover 5 and are rounded in the corners .
  • Parallel to the outer edges 6 'run mounting strips 12 which fix the cover after placing on the lower part 3 relative to the lower part 3 and the cooling elements 4 between the bottom of the lower part 3 and the cover 5.
