Abstract
Abstract A vacuum operated fluid-collection bottle incorporating optimum seal and locking structure at the cover and container thereof. This is effected by supplying, relative to the vertical transverse cross section thereof, an arcuate seal of essentially long-length, this being followed by one or more, corner or wedgetype penetrating seals, as well as a permissible final seal, to further increase the efficiency of the vacuum-seal. The resultant annular seal of the cover relative to the container increases the efficiency at which the unit is operated and increases the allowable vacuum pressure to be applied to the bottle. Provision is also made for pressure-surge cover release.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
In the combination an aspiration container and a cover releasably secured thereto, said cover including fluid inlet and vacuum ports, an improvement wherein said cover is resilient and includes a peripheral, outer flange portion having, progressing upwardly, an annular, outwardly sloping, inner side-wall surface, said container including an axially extending and radially outwardly extending annular lip, said lip having an exterior annular edge medial of the axial length of said lip and exterior is snapped onto and thereby installed over said lip.
Claim 2
Dependent Claim
82 words
In the combination an aspiration container and a cover releasably secured thereto, said cover including fluid inlet and vacuum ports, an improvement wherein said cover is resilient and includes a peripheral, outer flange portion having, progressing upwardly, an annular, outwardly sloping, inner side-wall surface, said container including an axially extending and radially outwardly extending annular lip, said lip having an exterior annular edge medial of the axial length of said lip and exterior is snapped onto and thereby installed over said lip.
Claim 3
Dependent Claim
21 words
The structure of claim 1 wherein said cover includes an interior, depending annular bead uniformly spaced from said outer flange portion.
Claim 4
Dependent Claim
19 words
The structure of claim 2 wherein said cover includes a central, dish-shaped concave portion disposed centrally of said bead.
Claim 5
Dependent Claim
13 words
The structure of claim 1 wherein said bead engages said container interiorly thereof.
Claim 6
Dependent Claim
19 words
The structure of claim 1 wherein said inner side wall surface overlaps and seals against said annular lower edge.
Claim 7
Dependent Claim
23 words
The structure of claim 5 wherein said cover includes a lower, annular inner camming surface below and contiguous with said inner side-wall surface.
Claim 8
Dependent Claim
80 words
In combination, a container having opposite, wall surfaces and forming a radially outwardly extending lip said lip having a central annular planner edge, and an annular planar lower edge, and a resilient cover having an annular, outer flange portion and a mutually spaced, interior depending bead, said outer flange portion and bead engaging said opposite wall surfaces and thereby mutually receiving said lip of said container whereby said exterior edges sealingly penetrate the exterior of said flange of said cover.
Claim 9
Dependent Claim
80 words
In combination, a container having opposite, wall surfaces and forming a radially outwardly extending lip said lip having a central annular planner edge, and an annular planar lower edge, and a resilient cover having an annular, outer flange portion and a mutually spaced, interior depending bead, said outer flange portion and bead engaging said opposite wall surfaces and thereby mutually receiving said lip of said container whereby said exterior edges sealingly penetrate the exterior of said flange of said cover.
