Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
80 words
A molded thermoplastic container and lid assembly including a peripheral U-shaped channel on the container and a complementarily-dimensioned inverted U-shaped channel on the lid having an outer flange and an inner flange and adapted to interlock with the U-shaped channel on the container, wherein the channel on the lid is slightly constricted at its opening and the portion of the container channel which interlocks with the lid channel is relatively narrow at its base and relatively wide at its terminus.
Claim 2
Dependent Claim
80 words
A molded thermoplastic container and lid assembly including a peripheral U-shaped channel on the container and a complementarily-dimensioned inverted U-shaped channel on the lid having an outer flange and an inner flange and adapted to interlock with the U-shaped channel on the container, wherein the channel on the lid is slightly constricted at its opening and the portion of the container channel which interlocks with the lid channel is relatively narrow at its base and relatively wide at its terminus.
Claim 3
Dependent Claim
25 words
The container and lid assembly of claim 1 wherein the lid channel includes an angled surface for guiding the interlocking portion of the container channel.
Claim 4
Dependent Claim
21 words
The container and lid assembly of claim 1 wherein the outer flange of the lid channel itself has a U-shaped cross-section.
Claim 5
Dependent Claim
30 words
The container and lid assembly of claim 1 wherein the inverted U-shaped channel on the lid and the inner flange of the U-shaped channel on the container are complementarily tapered.
Claim 6
Dependent Claim
27 words
The container and lid assembly of claim 4 wherein the tapering of the lid channel and the container flange is at an angle of about five degrees.
Claim 7
Dependent Claim
22 words
The container and lid assembly of claim 1 wherein the thermoplastic material has a flexural modulus of about 125,000 to about 225,000.
Claim 8
Dependent Claim
21 words
The container and lid assembly of claim 1 wherein the outer flange on the lid has an annular channel within it.
Claim 9
Dependent Claim
42 words
The container and lid assembly of claim 1 including also concentric peripheral flanges on the bottom of said container and a peripheral rim on the top thereof for nesting between said concentric flanges when one container is stacked on top of another.
Claim 10
Dependent Claim
20 words
The container and lid assembly of claim 1 wherein the lid has a peripheral lip spaced apart from said container.
Claim 11
Dependent Claim
33 words
The container and lid assembly of claim 1 wherein the U-shaped channel on the container is part of a circular chime held in place partly by an internally-directed dependent ring on said container.
Claim 12
Dependent Claim
48 words
A thermoplastic container and lid assembly comprising (a) a cylindrical container having a circular vertical flange which is tapered from a relatively narrow base to a relatively wide terminus and (b) a lid therefor having a channel complementarily dimensioned and tapered for insertion of said vertical flange therein.
Claim 13
Dependent Claim
48 words
A thermoplastic container and lid assembly comprising (a) a cylindrical container having a circular vertical flange which is tapered from a relatively narrow base to a relatively wide terminus and (b) a lid therefor having a channel complementarily dimensioned and tapered for insertion of said vertical flange therein.
Claim 14
Dependent Claim
25 words
The container and lid assembly of claim 11 wherein the channel on said lid has an angled surface to guide said vertical flange into it.
