[0001] The present invention generally relates to mechanisms for sealing containers and more particularly to mechanisms for safety sealing and covering of containers allowing repeatable covering and opening of a container's opening especially yet not exclusively for food and beverages containers.
BACKGROUND OF THE INVENTION
[0002] Manufacturers of food and beverage cans typically use pull-tab sealing and opening mechanism or stay-on tabs, in which a tab is used to tear off the can top (full aperture end) or designated part thereof for leaving an opening at the can top. In the pull tab mechanism, the tab is removed from the can whereas in the stay-on tab the tab remains after the opening is revealed.
[0003] Other solutions involve press button mechanisms, in which a designated opening in the can upper face is sealed by using soft connection of the sealer to the opening rim requiring pressing the softly connected seal downwards towards the inner space of the can for opening thereof.
[0004] These solutions are vulnerable to spilling or gas flow or entrance of dirt after the press button is teared, in case the can is tilted or falls.
