Weck jar

The jars were invented and patented by Rudolph Rempel.

In 1902, Weck left the company, Van Eyck continued to improve the design and function of the jar, and started exporting the jars outside of Germany.

He trademarked the name WECK and his strawberry logo is still used today.

Food is processed in Weck jars using the water bath canning technique, not a pressure canner.

During the canning process the lids are secured by the clips which can be removed once the processing is complete and the jars have cooled since the lid is being forced shut by atmospheric pressure.
