Definitions

  • the invention relates to a lockable Container for holding before temperature changes goods to be protected, in particular refrigerated goods, with at least one closure element, the at least a seal that takes effect in the closed position is assigned for the respective sealing gap.
  • Known closable containers of the The aforementioned genus are e.g. B. refrigeration cabinets whose Locking elements as doors or drawers are trained.
  • the container is common equipped with a refrigerator so that the Temperature inside the container for Cooling of the refrigerated goods can be lowered accordingly can.
  • the one Avoids heat conduction through the wall.
  • Sealing gap assigned a seal, so that the Sealing gap in the closed position of the respective Closure element is sealed.
  • the invention is based on the object Container of the aforementioned type to provide which regarding its Isolation, especially in terms of Condensation critical area of everyone Closure element associated sealing gap is improved.
  • each seal is an extruded profile, which, following the course of the respective sealing gap, is attached such that the seal at least partially with predetermined ones Profile areas located in the sealing gap, and that at least the predetermined profile area of the Seal is elastically deformable, such that resulting from closing forces Contact pressure to fill in the form-fitting Sealing gap leading flattening of the seal causes, the attachment of the seal such is that formed by the flattening Sealing surfaces of the seal on one walls of the respective sealing gap Container or the closure element so concern that in the area of a Dew point sections of the walls, that limit a sealing gap are covered.
  • the dimensioning and shaping of the profile of the Seal are essentially involved profile areas chosen that the seal, or its profile areas the predetermined width of the predetermined At least fill in the sealing gap.
  • the closed position press the sealing gap bounding walls of the container or Closure element thus the seal, at least however, their elastically deformable profile area so together that the seal adheres to this Walls optimally created, the in the area of a Dew point lying sections of the walls bounding each sealing gap be completely covered.
  • the covered Sections of the walls are therefore not in contact with Air, so that condensation in the air contained moisture in an advantageous manner in these critical areas is prevented.
  • the with unwanted condensation There is therefore no danger of icing.
  • This is especially for refrigerated cabinets with metallic Relevant surfaces that have a high Have thermal conductivity so that the dew point may lie outside the refrigerator.
  • the predetermined profile areas each Seal from the inside of the container in extend the sealing gap.
  • each Closure element may be arranged.
  • the strand-shaped seal can for example be along the walls bounding the respective sealing gap of the closure element, which Locking element a door, a drawer or the like can be.
  • the seal is with that Closure element for example glued or the like firmly connected.
  • the seal releasably on the walls of the Closure element, for example by means of Screw connection, is attached.
  • the walls of the closure element to the predetermined profile areas of the seal adapted Have shapes in which the extruded profile trained seal can be used form-fitting, z. B. can be inserted.
  • any seal Sections of the respective sealing gap bounding walls of the container is held.
  • the seal is thus arranged in a stationary manner.
  • the seal can turn detachable or fixed with the sealing gap facing Sections of the inner walls of the container be connected.

  • the Breakthroughs can also be used to attach Storage for the interior of the container dividing shelves can be used. Around to get a continuous surface that too the openings are easy to clean a poorly heat-conducting material, e.g. Silicone, be closed.
  • Breakthroughs circular, but other z. B. oval, angular or the like forms of Breakthroughs are possible.
  • the shape of the breakthroughs can the intended purpose, z. B. for attaching the closure elements or Fitted shelves.
  • Multiple breakthroughs can e.g. B. be arranged in series, wherein preferably several rows of openings are arranged side by side.
  • the breakthroughs adjacent rows are marked with particularly advantageous offset from each other, making one for heat conduction in the wall effective cross-section is further minimized.
  • the thermal insulation property of a usually made of thermally insulating material existing gasket will advantageously improved in that as an extruded profile trained seal at least one cavity having.
  • the cavity has a thermally insulating effect. Cavities can also be used to hold Braces are used.
  • a preferred embodiment of the invention provides before that the seal is tubular is.
  • a rubber-like plastic such as. B.
  • Foam rubber used as a material for the Seal.
  • Foam rubber has the advantage that because of its cellular structure, has low thermal conductivity and as an insulator works.
  • Foam rubber is also beneficial forms pure so that an existing one Seal due to the special elastic Property of this material optimal to the walls or surfaces to be sealed.
  • the tubular one Seal at least one form-keeping element.
  • the form-keeping element can be one in the tubular seal received component in the design of a profile, the Profile shape depending on the design of the seal Sealing gap is arbitrarily selectable.
  • Such Seal has the advantage that the shape specification by the profile designed as a form-keeping element by the contact pressure in the closed position of the Closure element caused elastic deformation the seal, especially its predetermined one Profile areas, so pretending that they adhere to the the respective sealing gap bounding walls of the Container or the closure element optimal hugs.
  • the Shape retention elements can also be used to create a secure attachment of the seal to the Closure element or container, e.g. B. by Screw on as a form-keeping element trained profile on a sealing gap limiting wall, to ensure.
  • the closure element in terms of size dimensioned to match the inside dimensions of the Container is adjusted and in the closed position an inside of the container is adjacent. If that Locking element is designed as a door, so So the door does not hit the wall of the Container, but is inserted inside.
  • the seal is then conveniently on the end faces the closure element arranged so that the Seal between the inside of the container and the end faces of the closure element for Commitment comes.
  • the seal is preferably designed so that the Seal on the surface a little Has coefficient of friction.
  • elastic fabric layer can be achieved for example made of polyester and on the back with a soft elastic material is coated.
  • rubber, Foam rubber or PVC are used.
  • each predetermined Profile area of the seal made of thermal insulating and soft elastic material with a hardness ⁇ 70 Shore exists.
  • Such one Material gives those who serve as contact surfaces Profile areas a high elastic Deformability, with which the profile areas optimal to any given shape of the can create walls that delimit a sealing gap.
