There are plenty of low-tech solutions that accomplish the same thing. For example: a ketchup syringe (but the "needle" end is wide, like those ends for decorating cakes with icing). Or a jar like a jam jar, which you can scrape out with a spoon. (Jam and ketchup are similar: mostly sugar, plus a bit of fruit.) There's a reason Heinz and others don't go with containers that empty 100%: such containers last longer, keeping you from buying more ketchup. What they want is jars that hold on to even more ketchup. Patent that!
