Claim Text:
1. A bladder closure comprising: a first rigid member adapted to be secured to a first side of a bladder opening, the first rigid member comprising at least one fastener mounting opening and at least one hole spaced from the fastener mounting opening; a second rigid member adapted to be secured to a second side of the bladder opening opposite from the first side, the second rigid member comprising at least one fastener engagement opening and at least one projection spaced from the fastener engagement opening; at least one fastener for securing the first and second rigid members together to seal the bladder opening, the fastener being rotatably mounted in the fastener mounting opening of the first rigid member, the fastener comprising a latch positioned on an outer side of the first rigid member and a shaft that passes through the fastener mounting opening and extends from an inner side of the first rigid member, wherein the shaft includes at least one tab that projects from a portion of the shaft on the inner side of the first rigid member, and wherein the latch extends radially from a portion of the shaft on the outer side of the first rigid member and the latch includes a locking portion that pivots with the shaft at least partially around an axis of the shaft; wherein when the bladder closure is in an open position, the first rigid member is spaced apart from the second rigid member; and wherein when the bladder closure is in a closed position, the tab that projects from the fastener shaft is engaged with the fastener engagement opening in the second rigid member to provide a clamping force that clamps the first and second rigid members together to seal a bladder opening, and the projection of the second rigid member extends through the hole in the first rigid member and the locking portion of the latch is engaged with the projection on the outer side of the first rigid member to lock the fastener in the closed position; wherein the locking portion of the latch includes a first locking surface and the projection includes a second locking surface, and in the closed position the first and second locking surfaces are pressed against each other, such that the engagement between the locking portion of the latch and the projection creates a second clamping force that urges the first and second rigid members together.
