Abstract
A wraparound recoverable closure, wherein a portion of the closure is not recovered against a substrate, which has a flap to seal across the gap between the abutting edge portions of the closure. Where the closure does not recover against and contact a substrate, the flap does not seal adequately for some applications. This invention provides means for supporting the flap to improve the seal. The preferred embodiment is a bag inside the closure which contains a resilient liner which supplies pressure on the flap to seal the flap across said gap.
