ABSTRACT:
A dispensing closure for a container that includes closure walls, at least one dispensing aperture, at least one closing element that is movable between a position where the aperture is closed, and a position where the aperture is open. This closure includes at least one actionable member that surrounds the closure walls and the closing element, a spring element disposed between the closing element and the closure walls to force the closing element to close the aperture, a connection device that includes a flexible pouch containing a temperature dependent material, and a catch mechanism. When the temperature is below a predetermined safety temperature the temperature dependent material is rigid enough so that the pouch restrains the catch mechanism in a position where the consumer can open the dispensing aperture by moving the actionable member, but when the temperature of the container is above the safety temperature, the temperature dependent material is sufficiently fluid so that the pouch is compressible to allow movement of the actionable member independently of the closing element, thus preventing a consumer from opening the dispensing aperture.
