Astra Sweets were looking for a way to reduce the weight of their candy jars - with success. Each jar now weighs 1,8 grams less than before (22,1 grams instead of 23,9 grams).
In addition, small stiffening ribs were added to the upper edge of the jar. Visually, the weight reduction is noticeable by the absence of a border at the bottom of the jar. Besides the savings in materials used, the cost price of the jar has also been lowered. Once the re-closable jar is empty, the consumer can use it for other applications, such as freezing food products.
