Q: How does a TightVac work?
A: The concept is simple; as the cap is pushed down air is displaced or sucked out of the container through a button on the cap; thus creating a vacuum seal. It is very difficult to pull the cap off without pressing the button. Simplicity that works!
Q: Are TightVacs dishwasher and microwave safe?
A: Unfortunately, no. TightVacs must be hand-washed. The intense heat in dishwashers and microwaves can warp your TightVac.
Q: Can TightVacs be used in the refrigerator?
A: Absolutely! TightVacs are perfect for condiments, pickles, leftovers, and more.
Q: Cap is too loose for you? Does yours pull off easily without pressing the button?
A: This is completely normal when your container is new. In the past, Tightvac caps were designed to fit the container body as snug as possible. After performing extensive testing on how to make our Vacs last longer (regardless if they are used in the home, place of business or for traveling) we found that producing caps with a slightly looser fit can actually double the Vac's lifespan while still maintaining an airtight vacuum seal! The more a Tightvac is opened and closed, the tighter the seal becomes; thus making Tightvacs the world's first truly sustainable container.
The new Tintvac line (Colbalt, Emerald, Rose & Mocha) is made from a different plastic material and therefore more slippery than the clear and solid color models. When new, the Tintvac caps appear to slide off easier than the non-tinted models. This is normal and after a few weeks of use, the caps will become more difficult to pull off without pressing the button. When properly maintained, this material has the ability to last for 5 years and beyond.
Q: Is it OK to use the 1lb CoffeeVac, even if I only store about 12 oz of coffee or less at a time?
A: The amount of product stored does not matter - it will create a vacuum whether the CoffeeVac is full or 10% - So this is no problem.
