Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 218 words
A barrel for handling large quantities of bulk material such as meat and other food products, comprising a molded plastic barrel having a bottom wall and a cylindrical side wall extending upwardly from the bottom wall, a rim extending circumferentially around the top of the cylindrical side wall, nesting stop means formed near the top of the side wall and flaring outwardly for facilitating nesting and unnesting of the barrel in a similar barrel by limiting the distance an upper nesting barrel extends into a lower nesting barrel, rim support means integrally formed in the top portion of the barrel side wall and extending from the rim of said barrel to the top of the nesting stop means for strengthening and supporting the rim and the barrel, said rim support means sloping outwardly from the stop means to the rim, recessed handle means integrally formed between the rim support means for providing handles for an operator handling the barrel, and inward projections of the recessed handle means extending inside the barrel adapted to support the nesting stop means of an upper barrel nested in a lower barrel and providing spaces between said inward projections to allow air to pass between nesting barrels so that a vacuum is not formed between nesting barrels to make pulling them apart difficult.
Claim 2
Dependent Claim 218 words
A barrel for handling large quantities of bulk material such as meat and other food products, comprising a molded plastic barrel having a bottom wall and a cylindrical side wall extending upwardly from the bottom wall, a rim extending circumferentially around the top of the cylindrical side wall, nesting stop means formed near the top of the side wall and flaring outwardly for facilitating nesting and unnesting of the barrel in a similar barrel by limiting the distance an upper nesting barrel extends into a lower nesting barrel, rim support means integrally formed in the top portion of the barrel side wall and extending from the rim of said barrel to the top of the nesting stop means for strengthening and supporting the rim and the barrel, said rim support means sloping outwardly from the stop means to the rim, recessed handle means integrally formed between the rim support means for providing handles for an operator handling the barrel, and inward projections of the recessed handle means extending inside the barrel adapted to support the nesting stop means of an upper barrel nested in a lower barrel and providing spaces between said inward projections to allow air to pass between nesting barrels so that a vacuum is not formed between nesting barrels to make pulling them apart difficult.
Claim 3
Dependent Claim 49 words
The barrel of claim 1, said rim support means for supporting the rim being a plurality of gussets integrally formed in the top portion of the barrel and extending from the rim to the top of the nesting stop means and slanting outwardly and upwardly from the side wall.
Claim 4
Dependent Claim 55 words
The barrel of claim 1, said recessed handle means being a plurality of depressions integrally formed in the barrel that extend from the top of the nesting stop means to behind the rim and above the bottom of the rim to form grooves and handle lips for ease of gripping and handling of the barrel.
Claim 5
Dependent Claim 69 words
The barrel of claim 1, said nesting means including a circumferential stop shoulder located at a point below the rim support means and recessed handle means, said top shoulder flaring inwardly from top to bottom, whereby with an upper barrel placed in a lower barrel the circumferential stop shoulder of the upper barrel engages and rests against the inward projections of the recessed handle means of the lower barrel.
Claim 6
Dependent Claim 12 words
The barrel of claim 1, said barrel being made of FDA-approved polyethylene.
Claim 7
Dependent Claim 11 words
The barrel of claim 1, said barrel being of seamless construction.
Claim 8
Dependent Claim 34 words
The barrel of claim 1, said bottom having a recess so as to form a circumferential bottom grasping ridge for utility in tipping and dumping of the barrel and for engaging a stacking lid.
Claim 9
Dependent Claim 22 words
The barrel of claim 7, having a stacking lid with a circumferential channel for engaging the circumferential bottom ridge of another barrel.
Claim 10
Dependent Claim 40 words
The barrel of claim 8, said stacking lid having securing means to attach the stacking lid to the barrel, the securing means being snaps which depend from the stacking lid and engage the handle lip of the recessed handle means.
Claim 11
Dependent Claim 471 words
A barrel for handling large quantities of bulk material such as meat and other food products, comprising a molded plastic barrel having a bottom wall and a cylindrical side wall extending upwardly from the bottom wall, a rim extending circumferentially around the top of the cylindrical side wall, nesting stop means formed near the top of the side wall and flaring outwardly for facilitating nesting and unnesting of the barrel in a similar barrel by limiting the distance an upper nesting barrel extends into a lower nesting barrel, rim support means integrally formed in the top portion of the barrel side wall and extending from the rim of said barrel to the top of the nesting stop means for strengthening and supporting the rim and the barrel, said rim support means sloping outwardly from the stop means to the rim, recessed handle means integrally formed between the rim support means for providing handles for an operator handling the barrel, and inward projections of the recessed handle means extending inside the barrel adapted to support the nesting stop means of an upper barrel nested in a lower barrel and providing spaces between said inward projections to allow air to pass between nesting barrels so that a vacuum is not formed between nesting barrels to make pulling them apart difficult, said rim support means for supporting the rim being a plurality of gussets integrally formed in the top portion of the barrel and extending from the rim to the top of the nesting stop means and slanting outwardly and upwardly from the side wall, said recessed handle means being a plurality of depressions integrally formed in the barrel that extend from the top of the nesting stop means to behind the rim and above the bottom of the rim to form grooves and handle lips for ease of gripping and handling of the barrel, said nesting means including a circumferential stop shoulder located at a point below the rim support means and recessed handle means, said top shoulder flaring inwardly from top to bottom, whereby with an upper barrel placed in a lower barrel the circumferential stop shoulder of the upper barrel engages and rests against the inward projections of the recessed handle means of the lower barrel, said barrel being made of FDA-approved polyethylene, said barrel being of seamless construction, said bottom having a recess so as to form a circumferential bottom grasping ridge for utility in tipping and dumping of the barrel and for engaging a stacking lid, having a stacking lid with a circumferential channel for engaging the circumferential bottom ridge of another barrel, and said stacking lid having securing means to attach the stacking lid to the barrel, the securing means being snaps which depend from the stacking lid and engage the handle lip of the recessed handle means.
