High Meat and Mason Jars

[Coatue]

I bought some mason jars at good ole Walmart yesterday. They are the screw top ones, http://www.walmart.com/ip/Ball-Quart-Mason-Jars-With-Lids-and-Bands-12-Pack/8033243 . They say you have to emerse them in boiling water to seal. Obviously I can't/no point to do this if I am going to open the jar for a minute every day. If I just screw the tops on and off without the seal from boiling, is it still air tight and safe to use? They a little metal disc lid in the middle and then the ring that screws on around it.

Just screw the top on; you'll be fine.
Those directions are for when you're canning foods and need it to remain airtight for months.
