practical standpoint for allowing the use of easily producible easily openable cover housing seals with a clean separation into the housing cover and sealant components without residual adherence of materials to one another the aforementioned tests revealed two disadvantages of the previous sealing bed design with regard to reopening 1 because the sealing substance lies volume wise in two main compartments on both sides of the base of the closure disk the sealing substance situated in the interior of the headlight must be pulled through the narrow area under the base in order to be withdrawn 2 the sealing substance must cover a larger width across the sealing bed line in order to compensate for deformations without too great an elongation of the material or constriction in this regard it is important that the repeat releasability does not result in premature failure during use for the deformations temperatures and forces that hereby arise and as a function of the load time and under the influence of media to this end the following theoretical considerations are presented when using an adhesive attachment of this embodiment forces act upon individual locations of the assembly parts to be joined which are determined by the rigidity of these materials distributed in two dimensions over the adhesive sealant the.
