The latest packaging for kids’ snacks is the single-use tube: Think of it as a baby bottle for kids who secretly still want to use one, and eat yogurt, applesauce, and smoothies. The reusable plastic pouches called Squeez’Ems ($7.99-$9.99 for two 6-ounce pouches), manufactured by BooginHead of Washington state, have removable screw tops, can be filled with your own mixtures, and — if they make it home from school — used again and again. They are actually easy to fill and clean. And here’s another (probably unintended) use: They are great salad dressing containers for grown-up brown baggers. No leaking if you follow the directions to turn the top clockwise. Something for everyone.
