Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
66 words
A plastic container, comprising: a base; a generally cylindrical sidewall extending upwardly from said base and defining an open top of said container opposite of said base, said sidewall including a section therein radially inset from said sidewall and adjacent said open top; and means within said inset section for stiffening said inset section in a direction essentially parallel to the longitudinal axis of said container.
Claim 2
Dependent Claim
66 words
A plastic container, comprising: a base; a generally cylindrical sidewall extending upwardly from said base and defining an open top of said container opposite of said base, said sidewall including a section therein radially inset from said sidewall and adjacent said open top; and means within said inset section for stiffening said inset section in a direction essentially parallel to the longitudinal axis of said container.
Claim 3
Dependent Claim
53 words
The container of claim 1, wherein said inset section includes at least a first portion defined by a circumferential depression in the interior surface of said sidewall and said stiffening means includes at least a first plurality of circumferentially spaced, longitudinally extending ribs formed integral with said sidewall and substantially within said depression.
Claim 4
Dependent Claim
51 words
The container of claim 2, wherein said inset section includes a second portion defined by a circumferential depression in the exterior surface of said sidewall and said stiffening means includes a second plurality of circumferentially spaced, longitudinally extending ribs formed integral with said sidewall and substantially within said last mentioned depression.
Claim 5
Dependent Claim
79 words
An injection molded, thermoplastic container adapted to have a lid removably installed thereon, comprising: a base; a generally cylindrical sidewall formed integral with and extending upwardly from said base, the top of said container opposite said base being open, said sidewall including a circumferentially extending depression in the interior surface thereof adjacent said top and defined by a pair of opposing surfaces of said sidewall; and means substantially within said depression for longitudinally reinforcing said sidewall at said depression.
Claim 6
Dependent Claim
79 words
An injection molded, thermoplastic container adapted to have a lid removably installed thereon, comprising: a base; a generally cylindrical sidewall formed integral with and extending upwardly from said base, the top of said container opposite said base being open, said sidewall including a circumferentially extending depression in the interior surface thereof adjacent said top and defined by a pair of opposing surfaces of said sidewall; and means substantially within said depression for longitudinally reinforcing said sidewall at said depression.
Claim 7
Dependent Claim
35 words
The container of claim 4, wherein said depression is essentially U-shaped in cross section and said reinforcing means includes a plurality of ribs extending longitudinally between said opposing surfaces and formed integral with the latter.
Claim 8
Dependent Claim
29 words
The container of claim 4, including a lip on said sidewall around said top and immediately above said depression, said lip being adapted for conjugally receiving said lid thereon.
Claim 9
Dependent Claim
27 words
The container of claim 4, wherein said container includes a circumferentially extending depression in the exterior surface thereof and longitudinal reinforcement ribs with said last mentioned depression.
Claim 10
Dependent Claim
90 words
A molded plastic container, comprising: a base; a generally cylindrical sidewall extending upwardly from said base and including a rim defining an open top on said container, said sidewall including a neck adjacent said top, said neck defining an area of reduced interior diameter in said sidewall; a lid removably secured on said rim; and means at said neck and extending longitudinally relative to the central axis of the container for reinforcing said neck in a direction parallel to said central axis, said reinforcing means being disposed below said rim.
Claim 11
Dependent Claim
90 words
A molded plastic container, comprising: a base; a generally cylindrical sidewall extending upwardly from said base and including a rim defining an open top on said container, said sidewall including a neck adjacent said top, said neck defining an area of reduced interior diameter in said sidewall; a lid removably secured on said rim; and means at said neck and extending longitudinally relative to the central axis of the container for reinforcing said neck in a direction parallel to said central axis, said reinforcing means being disposed below said rim.
