Screwdriver from the pharmacy
This tip was born with me out of necessity, because I often take something to eat for the break and sometimes something with sauce / dressing / other liquid components.
Unfortunately, I have had the case that a normal plastic box in the bag once thought to get a spontaneous vomiting attack and to give the (partly liquid) content of itself. Since then, I am proud of the faction of the parade-paranoia and have always packed everything with a lid again in a bag, so that nothing happens jaaaaaa.
But now I'm 1. the increased plastic bag consumption and 2. the Geraschle in my pocket terribly on the alarm clock. So there had to be a solution.
Ideally with screw cap.
Since I did not want to take anything out of glass (risk of breakage and schweeeer) fell options such as yoghurt glasses, etc. from the short list.
I found my solution in the pharmacy. There are these Screw- for homemade creams and ointments in different filling heights. The biggest I found was 500 ml.
The things are not expensive, light, stable and above all (so far anyway, knock on wood) absolutely tight.
I use the largest can by e.g. what to take from lunch. The 500 ml are perfect for the hunger at noon. I use my assortment of small to medium doses i.a. for dressings or for freezing.
Sure, there are also storage solutions from various Tipper-Flopper and Pups can makers for this case, but they also have their price. Therefore as an alternative this cheap version of it.
P.S. Unfortunately, I do not know if these things are suitable for a dishwasher because they do not want to own their own SPüMa, but they have survived hot flushing without grumbling. In the microwave, I would not even grab them first or possibly first without food in there test, obs to the nuclear plastic melt comes =)
