I have been experimenting with vacuum  bags and jars, for cooking application of vacuum. Being thrifty i found an easy 1-way valve many of us have at home right now.

What you need is

1. A coffee bag
2. A cutting device
3. A vacuum or in this case a Ziplock vacuum pump, used in their vacuum bag line

Its not perfect, and would probably need to have a piece of tape put over the slits on the front side to ensure the vacuum doesn't leak. As a food safe and easily replaceable 1-way valve, I think it has a lot of possibilities.
This whole thing told me absolutely nothing. It told what you need but did not say anything about how to make it.... <br>
Please tell how to make it, but thanks one way valves come in very handy
Another source is inside pump soap/shampoo/etc dispensers... although that sometimes depends.
Another source for cheap one-way valves are sip cups for children. Many of them have plastic valves that are removable for going in the dishwasher.
how about an instructable how to make it
