70mm Gold with No Button Plastisol Lined Lug Closure

Lugs instead of continuous threads are the distinct features of lug closures. The indented teeth of the closures latches onto the threads of lug jars to provide a secure grip and seal with the container. Different styles of lugs are available, such as having a safety button feature on the center of the cap that pops up when the seal is initially broken to indicate freshness. Also plastisol lining can be included to provide a completely hermetic (airtight) seal. Lug closures are commonly used for preserving foods and non-carbonated beverages.
