This product liability case involves a man who sliced his right hand while opening up a glass mason jar. He had purchased a set of 6 mason jars at a local wholesale retailer. The jars came with the metal lids and plastic seals already on. The plaintiff had previously opened 2 of the jars in the set without issue. On the day of the incident, the plaintiff was pulling the seal off the top of the jar when the glass shattered in his hand. An expert in consumer products safety was sought to inspect the remaining mason jars and provide an opinion as to whether or not they were structurally sufficient for their purpose.
