  • Patent number: 5653871
    Abstract: The present invention includes a liquid filtering filter head configured to receive a filter cartridge closure member, where the closure member has at least one seal member. The filter head has a generally cylindrical, inverted cup-like structure defining a chamber configured to receive the closure member and two openings in fluid communication with the chamber. Furthermore, the filter head features a guide for guiding a seal member as the closure member is inserted into the chamber, so that the seal member is prevented from becoming caught in the openings.
