Abstract
Disclosed are devices and methods for sealing containers. The device can include a seal, a spring, and an eccentric or ramp. In a first position, the spring and the seal can be retracted enabling the device to be placed in the opening of a container. In a second position, the spring can expand the seal enabling it to seal against a sealing surface of the container. The device can create a replaceable bottle cap assembly that conforms to the top of a non-threaded beverage container. The device can provide a lid for a variety of storage containers, including food storage containers. The device can form a watertight or airtight seal. The device can be used to form a movable lid for a container or to join multiple containers together.
