Abstract
Abstract A nestable container and an improved apparatus for and method of making same are provided wherein a blank is drawn to define a drawn container which is reverse redrawn to form the nestable container which has a side wall and an annular planar flange extending therefrom with a toroidal bead extending from the flange and having at least a portion thereof arranged within and beneath the peripheral edge of the flange. The container is adapted to be nested in a substantially identical container so that the toroidal bead separates the flange from the flange of a substantially identical container when the container is nested in the substantially identical container.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
A container comprising a. a side wall, b. an annular flange extending outwardly from said side wall, 1. said annular flange having a substantially planar top surface and a bottom surface, c. an outer arcuate portion having an outer surface adjoining said substantially planar top surface and an inner surface adjoining said bottom surface, d. and a reverse toroidal bead adjoiNing said outer arcuate portion, 1. said bead having a first annular increment facing toward said side wall so that the extension of said inner surface becomes the first annular increment of said bead and a second annular increment facing away from said side wall so that the extension of said outer surface becomes the second annular increment of said bead, 2. said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. and said outer arcuate portion providing vertical spacing between said flange and said bead.
Claim 2
Dependent Claim
165 words
A container comprising a. a side wall, b. an annular flange extending outwardly from said side wall, 1. said annular flange having a substantially planar top surface and a bottom surface, c. an outer arcuate portion having an outer surface adjoining said substantially planar top surface and an inner surface adjoining said bottom surface, d. and a reverse toroidal bead adjoiNing said outer arcuate portion, 1. said bead having a first annular increment facing toward said side wall so that the extension of said inner surface becomes the first annular increment of said bead and a second annular increment facing away from said side wall so that the extension of said outer surface becomes the second annular increment of said bead, 2. said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. and said outer arcuate portion providing vertical spacing between said flange and said bead.
Claim 3
Dependent Claim
54 words
said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. said outer arcuate portion providing vertical spacing between said flange and said bead, f. and means sealing said closure against said substantially planar top surface.
Claim 4
Dependent Claim
54 words
said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. said outer arcuate portion providing vertical spacing between said flange and said bead, f. and means sealing said closure against said substantially planar top surface.
Claim 5
Dependent Claim
25 words
A container as set forth in claim 1 in which said bead has a double thickness throughout at least a portion of its cross-sectional outline.
Claim 6
Dependent Claim
43 words
said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. and said outer arcuate portion providing vertical spacing between said flange and said bead.
Claim 7
Dependent Claim
43 words
said bead lying beneath the substantially planar top surface and having at least a portion thereof arranged within and beneath the outer peripheral edge of said outer surface, e. and said outer arcuate portion providing vertical spacing between said flange and said bead.
Claim 8
Dependent Claim
41 words
A container as set forth in claim 1 in which said first annular increment of said bead is arranged substantially adjoining the bottom surface of said annular flange by a distance which is less than the cross-sectional radius of said bead.
Claim 9
Dependent Claim
75 words
A container as set forth in claim 1 in which said side wall comprises a substantially frusto-conical side wall and said bead also has a portion thereof arranged outwardly of the outer peripheral edge of said outer surface, said container being adapted to be nested in a substantially identical container so that said bead separates said flange from the flange of a substantially identical container when the container is nested in the substantially identical container.
Claim 10
Dependent Claim
25 words
A container as set forth in claim 1 having a thermoplastic material defining its inside surface and having a thermosetting material defining its outside surface.
Claim 11
Dependent Claim
27 words
In combination: a container and a closure for said container; said container comprising: a. a side wall, b. an annular flange extending outwardly from said side wall,
Claim 12
Dependent Claim
27 words
In combination: a container and a closure for said container; said container comprising: a. a side wall, b. an annular flange extending outwardly from said side wall,
Claim 13
Dependent Claim
40 words
A combination as set forth in claim 6 in which said nestable container has a thermoplastic coating comprising its inside surface and said sealing means comprises a portion of said coating on said top surface heat sealed against said closure.
