One embodiment relates to an instant closure mechanism comprising first and second flat, strip like sealing structures having a first orientation, first and opposing second ends; first and opposing second edges; a first pivot member dividing the sealing structures into an first and second portions, and a contour including at least one curved portion having a large gradual radius intersecting at least one of the first end and the second end. At least two second pivot members having an orientation perpendicular to the first orientation; a tab member enabled to pivot from a first flat position to a second bent position, and a sealing member coupled to the tab member via the horizontal pivot member. The sealing members are joined, providing a sealing interface, and whereby pivoting the tab member imparts a deformation of at least one of the two sealing structures resembling the contour of the first pivot members.
