Abstract
A housing configuration for a liquid filter in which the housing is cup-shaped and is produced by a molding technique. The housing lid or lid is secured to the housing (10) by a course of threads (28) which can be produced without forming any undercuts. This is achieved inside an area (30) around the mold parting plane (29) by providing recesses (31) on the course of threads in the horizontal areas. As a result, the thread can be produced directly on the housing by the initial molding technique without any post-molding processing measures, so that manufacturing costs are reduced.
