Abstract
Abstract The present invention comprises a vacuum-operated, fluidcollection bottle and system. Structural advantages of the invention reside in increasing the effective seal area as between the cover and container of the bottle, as well as providing a tapered cam surface area receiving the bead of the container into the bead recess cover of the bottle. Dual vacuum bosses, one being valved, in multiple-boss covers may be used as respective automatic shutoff and tandem-fill means, with the nonapplicable 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 predetermine maximum fluid height within the bottle, either automatically or by valve adjustment.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
31 words
A fluid collection bottle including, in combination, a container having an upwardly convex bottom, and a cover having an upwardly convex top, said cover including plural, exteriorly connectable, bottle-interior communication ports.
Claim 2
Dependent Claim
31 words
A fluid collection bottle including, in combination, a container having an upwardly convex bottom, and a cover having an upwardly convex top, said cover including plural, exteriorly connectable, bottle-interior communication ports.
Claim 3
Dependent Claim
16 words
Structure according to claim 1 wherein said top includes intersecting stiffener ribs having rectilinear lower edges.
Claim 4
Dependent Claim
151 words
In the combination of a container and a cover secured thereover, an improvement wherein said container has a lip provided with peripheral, laterally extending, arcuate bead means, said cover including a spherically formed, concave-convex upper portion provided with fluid admittance and vacuum connection ports, said cover also including a depending flange having a correspondingly arcuate bead recess means dimensioned for sealingly receiving said arcuate bead means and also an outwardly extending peripheral flange portion contiguous with said flange at the latter''s lower extremity for facilitating detachment of said cover from said container, said depending flange having an inwardly tapered, annular, inner, bead-means camming surface disposed beneath said recess means, said cover being resilient whereby, when said cover is advanced toward and pressed over said bead means, said flange progressively expands outwardly and then returns to its nominal configurement when said bead means snaps into said bead recess for sealing disposition therein.
Claim 5
Dependent Claim
151 words
In the combination of a container and a cover secured thereover, an improvement wherein said container has a lip provided with peripheral, laterally extending, arcuate bead means, said cover including a spherically formed, concave-convex upper portion provided with fluid admittance and vacuum connection ports, said cover also including a depending flange having a correspondingly arcuate bead recess means dimensioned for sealingly receiving said arcuate bead means and also an outwardly extending peripheral flange portion contiguous with said flange at the latter''s lower extremity for facilitating detachment of said cover from said container, said depending flange having an inwardly tapered, annular, inner, bead-means camming surface disposed beneath said recess means, said cover being resilient whereby, when said cover is advanced toward and pressed over said bead means, said flange progressively expands outwardly and then returns to its nominal configurement when said bead means snaps into said bead recess for sealing disposition therein.
Claim 6
Dependent Claim
54 words

Claim 7
Dependent Claim
54 words
In the combination of a fluid collection bottle comprising a container and a cover secured thereover and forming a vacuum seal therewith: an improvement wherein said cover includes a fluid inlet port and plural vacuum openings, valve means interconnecting said vacuum openings, and means for connectIng exterior conduit means to one of said openings.
Claim 8
Dependent Claim
35 words
A fluid collector bottle including, in combination, a container having a spherically configured, concavo-convex bottom portion and a cover having a spherically configured, concavo-convey top portion, said cover including plural, exteriorly connectable, bottle-interior communication ports.
Claim 9
Dependent Claim
35 words
A fluid collector bottle including, in combination, a container having a spherically configured, concavo-convex bottom portion and a cover having a spherically configured, concavo-convey top portion, said cover including plural, exteriorly connectable, bottle-interior communication ports.
Claim 10
Dependent Claim
82 words
In a fluid collection bottle comprising a container and a cover secured thereover and forming a vacuum seal therewith: an improvement wherein said cover is of concavo-convex cross section and includes a fluid admittance port means and also a vacuum port means, both of said port means dependingly extending within said container, said vacuum port means extending to a level beneath that of said fluid admittance port means, and means constructed to connect said vacuum port means to a reduced pressure source.
Claim 11
Dependent Claim
82 words
