I haven't had that problem unless either the tube or the cap has a small crack in it. To make the cap have a more air tight seal I let a bit of the glue get on the threads of the tube before resealing it. Usually there's still plenty of glue left after the patches are used up so I put the old tube in the next patch kit for redundancy.
