Yet Another Vacuum Lunch Box

Yet another polypropylene container with a vacuum-making mechanism. A nicely made lunchbox with a snug fit cover and knob on center.

The knob triangle whole when aligned with the small circle hole allows free entry and exit of gases, food items and contaminants. Let open while the content is steaming hot then turn the knob closed after few minutes. Pump few times to drive some air out and create vacuum.

To open, align the triangle pointer to circle or marker just beside the PP symbol. The vacuum will be released. Then pull the lid up. As an alternate, the lid can be pulled up without releasing the vacuum first.

Well, I guess this vacuum lunch box is good for storing electronic components too. See for yourself!
