Abstract
Abstract A blow molded synthetic thermoplastic barrel one end wall of which has an eccentric opening surrounded be a ring-shaped mouth which, in turn, is surrounded by an arcuate groove having two open ends. The opening can be closed by a cover whose outer side is then flush with the outer surface of the major portion of the one end wall. Such outer surface is surrounded by a bead which can surround the other end wall of a second container when the two containers are stacked end-to-end. For the stacking of several containers side-by-side, the circumferential wall of the barrel has two longitudinally extending flats located diametrically opposite each other. The circular end portions of the flats extend into the domed end portions of the circumferential wall and close to the respective end walls.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A container, particularly a blow molded barrel consisting at least in part of synthetic thermoplastic material, comprising a circumferential wall having two stacking flats disposed opposite each other; a first end wall at one end of said circumferential wall; a second end wall at the other end of said circumferential wall, one of said end walls having an outer stacking surface, a circumferential bead having a serrated peripheral surface and extending outwardly beyond said outer surface so that it can surround the other end wall of a similar second container when the two containers are stacked end-to-end, an eccentric opening, a mouth surrounding said opening, and an arcuate groove surrounding at least a portion of said mouth; and a cover detachably secured to said one end wall to close said opening, said cover having an outer substantially planar stacking side which is at least substantially flush with and constitutes an extension of said outer surface of said one end wall so that a similar second container can be supported by said outer stacking surface of said one end wall and also by said outer stacking side of said cover when the two containers are stacked end-to-end.
Claim 2
Dependent Claim
196 words
A container, particularly a blow molded barrel consisting at least in part of synthetic thermoplastic material, comprising a circumferential wall having two stacking flats disposed opposite each other; a first end wall at one end of said circumferential wall; a second end wall at the other end of said circumferential wall, one of said end walls having an outer stacking surface, a circumferential bead having a serrated peripheral surface and extending outwardly beyond said outer surface so that it can surround the other end wall of a similar second container when the two containers are stacked end-to-end, an eccentric opening, a mouth surrounding said opening, and an arcuate groove surrounding at least a portion of said mouth; and a cover detachably secured to said one end wall to close said opening, said cover having an outer substantially planar stacking side which is at least substantially flush with and constitutes an extension of said outer surface of said one end wall so that a similar second container can be supported by said outer stacking surface of said one end wall and also by said outer stacking side of said cover when the two containers are stacked end-to-end.
Claim 3
Dependent Claim
47 words
A container as defined in claim 1, wherein said one end wall has a substantially circular outline and said mouth includes an internal surface surrounding said opening and having a substantially circular outline, the diameter of said internal surface approximating the radius of said one end wall.
Claim 4
Dependent Claim
14 words
A container as defined in claim 1, wherein said groove has two open ends.
Claim 5
Dependent Claim
43 words
A container as defined in claim 1, wherein said one end wall has a circumferential bead extending outwardly beyond said outer surface so that it can surround the other end wall of a similar second container when the two containers are stacked end-to-end.
Claim 6
Dependent Claim
60 words
A container as defined in claim 4, wherein said circumferential wall has domed end portions adjacent to and tapering toward the respective end walls, each of said flats having two substantially rounded end portions extending into the respective domed end portions of said circumferential wall, said bead having portions closely adjacent to the respective rounded end portions of said flats.
Claim 7
Dependent Claim
20 words
A container as defined in claim 4, wherein said circumferential wall has a substantially annular constriction adjacent to said bead.
Claim 8
Dependent Claim
55 words
A container as defined in claim 1, wherein said flats are elongated, as considered in a direction from the one toward the other of said end walls, and said circumferential wall has domed end portions adjacent to the respective end walls, said flats having portions extending into said domed end portions of said circumferential wall.
Claim 9
Dependent Claim
58 words
A container as defined in claim 7, wherein said cover and said mouth have projections which are interlinked with each other in at least one first angular position of said cover with respect to said mouth and are turnably disengaged from each other in at least one second angular position of said cover with respect to said mouth.
Claim 10
Dependent Claim
44 words
A container as defined in claim 1, wherein said end walls are round and said one end wall has a substantially annular bead extending said outer surface thereof and having an inner diameter at least slightly exceeding the diameter of the other end wall.
Claim 11
Dependent Claim
30 words
A container as defined in claim 1, wherein said serrated peripheral surface of said bead is comprised of a plurality of equally-spaced notches for facilitating the transport of the container.
