Abstract:
A closure assembly comprising:a flexible substrate having a first side flap opposed to a second side flap along an opening, the opening extending in a first direction; a resealable closure having portions affixed to the first side flap, and portions affixed to the second side flap, the closure being operable between a first closed position, in which the opening in the substrate is closed, and a second open position, in which the opening in the substrate is revealed; a spring member mounted to the substrate, the spring member having a first arm which is connected to the first side flap and a second arm which is connected to the second side flap, the spring member first arm being spaced in a second direction across the opening from the second arm, and connected to the second arm by a first connecting section, wherein the spring member is resilient, wherein a first plane is defined by the first direction and the second direction, and wherein the spring member is formed such that portions of the first arm are spaced from portions of the second arm in a direction perpendicular to the first plane when the spring member is undeformed, and when the closure is in the closed position, the first arm is brought into approximately the same plane as the second arm, such that the spring member urges portions of the first flap away from portions of the second flap in a direction perpendicular to the first plane when the closure is in the second open position.
