The hemispheric main body has a domed surface and a flat surface. The flat surface of the main body has a recessed region surrounding a central pillar. The resilient compressible component is housed within and attached to the recessed region of the hemispheric main body. The flexible magnetic disk is attached to the resilient compressible component. The piercing pin is attached to the hemispheric main body and held axially within the central pillar. A process of opening a vacuum-packed jar with the lid puncture device is also provided.
