Abstract:
1. A dispensing closure for a container that includes closure walls, at least one dispensing aperture, at least one closing element that is movable relative to the closure walls between a first position where said dispensing aperture is closed, and a second position where the dispensing aperture is open and the product is dispensed, at least one actionable means that surrounds the closure walls and closing element, and a spring element disposed between the closing element and closure walls so as to naturally force the closing element in a position where it closes the aperture, with the dispensing closure including at least one connection device comprising: a flexible pouch containing a temperature dependent material, and a catch mechanism adjacent the pouch which can move between a position where it operatively connects the closing element and the actionable means and a position where the catch mechanism allows the actionable means to move independently of the closing element, so that when the temperature of the container is below a predetermined safety temperature the temperature dependent material is rigid enough that the pouch restrains the catch mechanism in the position where it operatively connects the closing element and the actionable means, thus allowing a consumer to open the dispensing aperture by moving the actionable means, and when the temperature of the container is above the safety temperature the temperature dependent material is sufficiently fluid that the pouch is compressible by the catch mechanism so that the catch mechanism moves to the position where it allows the actionable means to move independently of the closing element, thus preventing a consumer from opening the dispensing aperture by moving the actionable means.
