Claim 14:
15. A printing fluid container fora printing system, the printing fluid container comprising:
a container body including a threaded neck, the container body defining an interior chamber configured to hold printing fluid;
a threaded collar configured for selected application to the container body, the threaded collar having a spout in fluid communication with the interior chamber of the container body and a collar body with a sawtooth collar lip defining a plurality of interleaved collar ramps and collar risers arranged peripherally around an exterior of the collar body; and
a cap configured for selected engagement with the threaded collar to cover the spout, the cap including a skirt with a sawtooth cap lip defining a plurality of interleaved cap ramps and cap risers arranged peripherally around an interior of the skirt, the sawtooth cap lip being configured for selected complementary interfitment with the sawtooth collar lip;
wherein rotation of the cap in a first rotational direction effects removal of the cap from the threaded collar via cammed engagement between the cap ramps and collar ramps through no more than 90 degrees rotation of the cap; and
wherein rotation of the cap in a second rotational direction effects tightening of the threaded collar onto the container body via fixed engagement of the cap risers and collar risers to translate torque from the cap to the threaded collar.
