Definitions

  • the first sealing surface is equal to or larger, in particular larger, than the cross-sectional area of the tubular-section-shaped housing at the end of the housing. If the sealing surface is equal to the cross-sectional area of the tubular housing at the end of the housing, a particularly good sealing effect is ensured by optimum utilization of the possible sealing surface. In a preferred embodiment it can also be provided that the sealing surface is larger than the cross-sectional area of the tubular sectional housing is at the housing end. This can be guaranteed by designing the melting process in such a way that a larger amount of material is melted and a pinch is made during the subsequent joining process. Such a component has a bead-shaped sealing surface, which has an advantageous effect on the sealing effect. The bulge can also advantageously lead to a possible dead volume being further reduced, which is particularly desirable in particular in the case of flemodialysis.
