http://pz-mods.net/weapons-items/ReusableJars/
This mod creates a new item - an "Empty Jar with Lid" that can be reused. The jar and lid are treated as one single item and it will be returned to you after it's emptied, so that you can use it over and over again. The game's original jars and lids still exist, but this item will spawn in home kitchens, although it is moderately rare.
Please note, this will only work with the default canning foods - carrots, potatoes, etc. If you have a mod that allows you to can meat or anything else, this jar won't work for those recipes.
