Query: Trouble with the top, as designed

I have used this once, and probably for the last time. The lid will not stay attached to the base without extra weight. There is a very weak design to the lid closure that releases as you screw down the top. Basically the lid catches on the two short sides with a small 2 mm lip, one side having a press to push out release and the other acting as a hinge until the top is lifted or it is pressed towards the side engaged. The problem is the the top, when screwing the press down also bows out the lid and releases one or the other of these catches. It was very frustrating to screw the press and have the side release. My wife was thinking that I was too aggressive, so she operated it and the lid popped again for her as well. Finally held it down with a thick cookbook:(Joy of Cooking: 75th Anniversary Edition - 2006). Pickles were successfully produced, but not useful enough to use again. I would recommend a lid that itself screws down, then you can screw the press down.
