Gentle Readers may already be aware, but I have a fondness for canning jars as storage containers for herbs, including TPTSNBN (That plant that shall not be named). They are reasonably priced, airtight, and easy to clean. They can be dressed up with a little acid etching cream (see my article about that in Soft Secrets Magazine here). About my only complaint about them is that they are not opaque (they let light in), and they usually really aren’t all that attractive for use with company.
I was given one of these containers to try out, they are a TightVac container, distributed by Nickel City Wholesale Garden Supply. I have to say, I’ll reserve my final judgment until I’ve had more experience with it, but my initial impression is pretty favorable.
The idea seems sound to me. The lid is very deep, so a large quantity of air is trapped when it is first set onto the container. There is a little button near the top that opens a small valve, so by pressing the button, the volume of air trapped in the lid is allowed to escape, reducing the pressure inside the container to atmospheric normal, and letting the lid slide down over the container. What is nice about this container, is that since the pressure inside the closed container is the same as the local atmosphere, trying to remove the lid without pressing the button to open the valve causes a vacuum which holds the lid in place.
The plastic used is an opaque white, so light isn’t a problem, and it is an attractive container. Very appropriate for use with the herbs you plan on using soon handy, or bringing out for guests. If nothing else, the unusual closure method is worth a mention and a moment of “show and tell”.
I plan on using it enough to get a feel for it, and will let you know if I wind up liking it or not caring for it. So far I’ve been very pleased with it.
