Abstract
A fitment removal prevention device for insertion within a container having a rigid mouth portion. The device has a body portion and an incompressible member movable with respect to the body portion and biased from a first position, in which the device is insertable into the container, to a second position, in which the incompressible member engages the container and exerts a force on the mouth portion of the container in a first direction having a component transverse to the direction of extraction of the device from the container. Upon attempted extraction of the fitment removal prevention device from the container, the incompressible member exerts an increased force on the mouth portion of the container in the first direction, thereby retaining the device in the container.
