Pop top containers are incredibly secure despite a simple design – cylinders with sealed bottoms and hinged, circular caps. Designed and tested to be difficult for children to open, they're easy to open for adults and seniors. Pop top containers are more accessible to open than Push Down & Turn bottles and jars. To close Pop top containers, press the cap down until it clicks into place and fully seals. Written on the top of the op top container cap are the words ‘Squeeze Below Cap’– straightforward instructions for popping up the lid. Our pop top containers are certified by the American Society for Testing Materials (ASTM) as child-resistant.
