Storage containers with inner bladders for liquids, in particular for heating oil

The innovation relates to a storage container with a dome and with an inner bladder for liquids, in particular heating oil, in which a replaceable, leak-proof bladder that adapts to the internal dimensions of the container is formed within the storage container an easily deformable and in particular oil-resistant material is provided as a lining, with one near the lower one Provided on the edge of the dome, this surrounding double ring made of tough, especially ©! Resistant material, which can be pressed against the inner wall of the storage container and between whose contact surfaces the edge of the bladder can be clamped or retracted is.

These containers have become well established in practice, wise however, the lack of direct contact between the inner bladder and the steel wall of the container is present, thereby preventing the passage of air, fuel oil or water through the space between the bladder and the steel wall. Such a passage is necessary, however, in order to be able to operate the leak detection device prescribed for tanks of this type. Attempts have already been made by gluing in foam strips or tracks to create such passages, but this is difficult because the adhesive used on the mostly oily steel wall does not adhere well and the strips or Tracks loosen up again soon.
