Abstract The present invention comprises a vacuum-operated fluidcollection bottle and system including a serially-connected tandem system. Dual vacuum bosses for a representative bottle, one being valved, in multiple-boss covers may be used as respective automatic shut-off and tandem-fill means, with the non-applicable boss being releasably capped off. Two of the three conduit portions of the cover may be connected together through appropriate valving system so that either or both may be effective in supplying vacuum communication to the interior of the bottle at selected height levels. Valving means pre-determine maximum fluid height within the bottle, either automatically or by valve adjustment. A representative bottle may include fluid inlet and vacuum ports of differing level-dimension, to aid the lower vacuum port to close off or to conduct outwardly body-fluid while maintaining the inlet port above the bottle fluid level.
In a vacuum-fill bottle having a container and a cover secured thereto, said container having vacuum port means and fluid inlet port means; an improvement wherein said cover is dome-shaped, convex upwardly, and is provided with transverse centrally intersecting support ribs on its underneath side, said container and cover being provided with inter-engaging securement means constructed for optimum effectiveness when vacuum is applied to the interior of said bottle via said vacuum port means, the outer extremities of said support ribs being spaced from said securement means, whereby to permit said cover to deflect downwardly about the said outer extremities of said support ribs and thereby permit said inter-engaging securement means to seal.
